BACKGROUND
Technical Field. The invention relates generally to multi-purpose tools and their methods of use. More particularly, this application relates to apparatus and methods for splitting wood, especially to vehicle mounted apparatuses and methods for splitting wood, and apparatus and methods for material handling.
Splitting wood is a common task performed by people around the world. The split wood is used typically in fires for heating of building structures, saunas, campfires, and for the enjoyment of fire places. Splitting wood, however, can be a difficult task and therefore there has been an abundance of prior art directed to machines of various sizes for this purpose. However, even the simplest of these devices are too large and complex and lead to poor body mechanics. The standard for splitting wood into kindling is the axe, however the axe has proved to be dangerous since the method typically involves swinging an axe blade toward a user's opposing hand stabilizing the log.
The abundance of tools a person may collect to perform various tasks can become overwhelming eventually cluttering the garage and other work areas.
What is needed are log splitting devices and methods that are significantly safer than a hand axe, yet simple, effective, inexpensive, and highly portable. What is also needed are tools that take up less space and if possible, tools that can be utilized for more than one purpose thereby occupying less space.

DETAILED DESCRIPTION OF SELECTED EMBODIMENTS
Select embodiments of the article of invention will now be described with reference to the Figures. Like numerals indicate like or corresponding elements throughout the several views. Various embodiments having like or corresponding elements are distinguished by letters (i.e. 100A, 100B, 100C, 100AA). Embodiments described in the Specification and Drawings are fully supported as will be recognized by those skilled in the art. To avoid redundant explanation in the Specification and redundant labeling of elements in the Drawings, like elements are not re-described and/or relabeled in every instance. Some features described and illustrated for one embodiment, may optionally be utilized within other similar embodiments although not described or illustrated in the feature to again avoid redundant work. The terminology used in the description presented herein is not intended to be interpreted in any limited or restrictive way, simply because it is being utilized in conjunction with detailed description of certain specific embodiments of the invention. Furthermore, embodiments of the invention may include several novel features, no single one of which is solely responsible for its desirable attributes or which is essential to practicing the invention described herein.
FIGS. 1 through 4 illustrate an preferred embodiment of the article of invention. In this embodiment, a wood splitter 100A is illustrated housed within a hitch receiver 126 that is fixed to a vehicle 127 such as for example, a car, a truck, a UTV, and trailer. Although not required, a hitch pin 112 (which may take other forms such as a bolt) is extended through a hole bored through a hitch receiver 126 and passes through a fixation bore 116A on a fixation portion of wood splitter 100A. A hitch pin retainer 114 may be used to secure hitch pin 112 in position. In this embodiment, wood splitter 100A comprises a primary blade 118A and an optional secondary blade 120A extending at an oblique angle from the primary blade. In preferred forms, the oblique angle is generally 90 degrees. As noted in FIG. 2, the blade portion 102A of the wood splitter is spaced sufficiently from the vehicle thereby avoiding damage to the vehicle during splitting actions. In this embodiment and others, the wood splitter 100A is manufactured from metal, preferably steels and their alloys. In some embodiments the steels are stainless steels. However, any material having sufficient strength, ductility, and hardness may be used such as aluminum, and aluminum alloys. In some places, polymers may be used. Individual parts and assemblies of the article of invention may be formed by one or more of a range of manufacturing processes including machining, casting, and forging. In some embodiments, the tools are in the form of a single casted or forged part. All or a portion of the blade portions may be hardened or remain unhardened.
FIG. 3 illustrates a user positioning a log on a blade portion 102A of a wood splitter 100A secured within a hitch receiver 126 of a vehicle such as a truck. The user holds the side of a log 101 or other wood with one hand and impacts the top of the log with an impact tool 105 such as a hammer or mallet. The impact causes the log 101 to be driven down over a primary blade 118A (and secondary blade 120A if so equipped) and also over a deflector portion 130A of the splitter. As a consequence of this, the log 101 is split into smaller pieces. In some embodiments, a collector (such as 258I in FIG. 30) is positioned below a wood splitter to capture the smaller wood pieces (also referred to as kindling 103) as they fall from the wood splitter. A wood splitter according to some embodiments of this invention are configured for being slidingly received in standard size hitch receiver openings such as a 2 inch×2 inch hitch receiver, and in other embodiments for a standard 1.25 inch×1.25 inch hitch receiver, standard 2.5 inch×2.5 inch hitch receiver, and 3 inch×3 inch hitch receivers. However, it is conceived the device could be used in any other custom sized receiver. In addition, the disclosed wood splitter embodiments may be received in parts functionally equivalent to hitch receivers for splitting purposes such as splitter sleeve 388DD (FIG. 88).
Referring back to FIG. 1, it illustrates one embodiment of the article of invention. In this embodiment a wood splitter comprises a fixation portion 104A and a blade portion 102A formed from a body portion 128A. The fixation portion 104A is generally configured to be received in a hitch receiver 126 secured to a vehicle 127. In this embodiment, fixation portion 104A is in the form of a solid bar made of a metal such as steel. The blade portion 102A comprises a primary blade 118A and in this embodiment also comprises an optional secondary blade 120A extending generally perpendicular to primary blade 118A. The primary blade 118A and secondary blade both have a cut edge 132A with a primary edge face 134A and a secondary edge face 136A. One or more of a primary edge face and a secondary edge face may be vertical or sloped. In some embodiments, a primary edge face 134A and secondary edge face 136A seamlessly transition into a primary deflector face 138A and secondary deflector face 140A of a deflector portion 130A whereas in other embodiments there is a distinct transition such as a change in angle between them. In some embodiments, the primary edge faces and secondary edge faces are separated from the primary and secondary deflector faces by respective primary and secondary transition faces.
Edge faces, transition faces, and deflector faces may assume a variety of profiles not limited to generally flat, concave, and convex. In preferred embodiments, the aforementioned primary and secondary blade components face generally upward however in other embodiments the blade portions are vertical or downward. Distances between opposed edge, transition, and deflector faces increase moving inferiorly from the cut edges as illustrated in FIG. 4. Axis A and axis B extend from a cut edge 132A and generally follow the included surfaces below thereby defining a slope angle α. When the optional secondary blade is present, axis C and D extend from a cut edge of the secondary blade along the wedged surfaces defining a slope angle β. In preferred embodiments, these angles (α and β) range between 20 degrees and 80 degrees although they may assume values outside this range.
In some embodiments, a cut edge of a blade portion is generally centered between sloping faces of a blade portion (i.e. FIG. 22). In other embodiments such as illustrated in FIGS. 4 and 5, a cut edge 132A is offset to one side of body portion 128A. This offset tends to create steeper incline faces on one side versus the other. A cut edge offset to the right (FIG. 4) is preferable for right handed users, whereas a cut edge offset to the left (FIG. 5) is preferable for left hand users. Some embodiments include two cut edges so configured such that by rotating a wood splitter 90 degrees within a hitch receiver, a user may use a single wood splitter to perform left handed and right handed splitting.
Embodiments having a secondary blade 120A, it is preferable the second blade also includes one or more opposed primary and secondary edge faces, transition faces, and deflector faces. Distances between opposed edge, transition, and deflector faces increase moving inferiorly from the cut edge of a secondary blade as represented by the angle β (FIG. 4) between axis C and axis D each extending down opposing slopes.
In this and other embodiments, a fixation portion 104A and other aspects of a body portion 128A may be defined by a top face 154A, a bottom face 156A, a first side face 158A, and a second side face 160A. A proximal end face 146A and a distal end face 148A are positioned at the opposing ends. A fixation face 117A defines a fixation bore 116A extending between first side face 158A and second side face 160A. Fixation bore 116A has an elongate axis G and is characterized by a diameter sufficient to house a hitch pin 112. It is preferred that fixation bore 116A is generally aligned with a horizontal mid plane (plane E) and is generally perpendicular to first and second side faces 158A and 160A. Embodiments configured to accommodate both left handed and right handed users may include a secondary fixation bore (not shown) extending between bottom face 156A and top face 154A. An additional mid plane, plane F, is positioned vertically midway between the first and second side faces 158A,160A. A distal blade face 152A may extend between blade portion 102A and fixation portion 104A.
FIG. 4A illustrates a blade portion of the wood splitter of FIG. 4 having a plurality of relief grooves 404A extending into a primary deflector face 138A of a blade portion 102A. The relief grooves 404A may be utilized in a variety of wood splitter embodiments having either primary or secondary deflector faces.
FIGS. 6-8 illustrates yet another embodiment of the article of invention. In this embodiment of a wood splitter 100B, a blade portion 102B comprises a blade extension 162B configured for seating within fixation recess 164B and held by one or more of; fasteners such as screws and pins, and welds. Blade extension 162B is defined by one or more of; a first side extension wall 166B, a second side extension wall 168B, an upper extension wall 170B, and a lower extension wall 172B. Fixation recess 164B comprises one or more of; an upper recess wall 178B, a lower recess wall 180B, a first side recess wall 174B, and a second side recess wall 176B. Fixation portion 104B comprises a proximal tube wall 182B and a distal tube wall 184B terminating the ends. As illustrated in FIG. 8, in some embodiments blade portion 102B does not comprises a four sided blade extension whereas the blade extension is two sided and is instead seated on second side extension wall 168B and lower extension wall 172B against respective second side recess wall 176B and lower recess wall 180B.
FIGS. 9 and 10A illustrate another embodiment of the article of invention equipped with a guide portion. In this embodiment, guide portion 106C comprises a guide wall 186C having a guide surface 188C formed thereon. Extending from guide wall 186C is a first guide leg 190C which is spaced from a second guide leg 192C. Body portion 128C is equipped with one or more guide receivers. The guide receivers may be in the form of a bored hole or may assume other forms capable of securing one or more guide legs and guide feet if present. In this embodiment, wood splitter 100C comprises a first guide receiver 108C disposed in top face 154C and a second guide receiver 110C disposed in proximal end face 146C however the guide receivers may be positioned at other faces such as a second side face. As illustrated here, a guide leg may include a guide foot portion such as the second guide foot 196C which is housed within second guide receiver 110C. Each guide receiver may comprise a radial guide face defining the walls of the bore and an end guide face at the bottom of the bore.
FIG. 10B illustrates a variation of the guide portion 106C illustrated in FIG. 9. The embodiment in FIG. 9 has a generally horizontal guide wall 186C with guide surface 188C formed thereon having a curved or semi-circular shape. In contrast, guide portion 106C in FIG. 10C comprises a generally horizontal guide wall 186C with guide surface 188C that is generally linear along a portion adjacent cut edge 132C.
Guide portion 106C in FIGS. 9, 10A, 10B, and 10C are configured to have a deflectable insertion. Therefore, to attach guide portion 106C to body portion 128C, first guide leg 190C is inserted in first guide receiver 108C, then guide portion 106C is pivoted such that second guide foot 196C is near second guide receiver 110C. The user applies a force to second guide leg 192C to deflect it far enough to clear proximal end face 146C until it can be aligned with second guide receiver 110C. The user then releases second guide leg 192C thereby allowing it to spring into second guide receiver 110C thus securing it in position. A reverse of these steps are used to remove guide portion 106C from body portion 128C.
FIGS. 11-13 illustrates another embodiment of the article of invention also equipped with a guide portion 106D. In this embodiment, a proximal end of blade portion 102D comprises a guide boss 198D configured with a first guide receiver 108D positioned generally vertical along axis K in this embodiment and disposed in a generally horizontal positioned guide boss face 199D. A second proximal end face 147D transitions between guide boss 198D and cut edge 132D. First pin recess 200D houses first lock pin 206D, and second pin recess 202D houses second lock pin 208D and third pin recess 204D in first guide leg 190D houses third lock pin 210D. When first guide leg 190D is inserted into first guide receiver 108D, motion of guide portion 106D is limited by third lock pin 210D being captured between first lock pin 206D and second lock pin 208D. In addition, third lock pin 210D may be used to set first guide leg 190D vertical position within first guide receiver 108D. In this embodiment, guide portion 106D is an “L” shape. Guide portion 106D may be configured to lift out and be removed by the user, or may be fixed within by a pin, screw, weld or other means. For example, a fourth lock pin 214D can be seated within fourth pin recess 212D at the inferior end of first guide leg 190D to limit travel (FIG. 17-18).
FIG. 14 illustrates a similar wood splitter 100D embodiment however, guide portion 106D is in the shape of a “T”. The shape of guide portion 106D may be fashioned into a wide range of shapes. FIG. 15 illustrates a top view of a “T” shaped guide portion 106D. FIG. 16 illustrates a partial view of a “T” shaped guide portion having a buffer leg 216D to soften contact by a user. FIGS. 17 and 18 illustrate an embodiment wherein a first guide leg 190D comprises a pivot joint 218D thus providing an option to fold a superior portion of a guide portion 106D down over primary blade 118D in a storage mode thereby reducing the profile and shielding a user from accidental harm. During operation, guide portion 106D is lifted upright and lowered into first guide receiver 108D consequently aligning pivot joint 218D along axis K and locking it as illustrated in FIG. 18. Third lock pin 210D holds the vertical position.
FIG. 19-20 illustrates another embodiment of the article of invention equipped with both a primary blade 118E and a secondary blade 120E aligned generally perpendicular to each other. The secondary blade option provides for the creation of an additional wood piece during each wood splitting cycle. In this embodiment, body portion 128E is in the form of a generally square elongate tube although the illustrated embodiment and other embodiments may alternatively use a solid elongate bar, U-channel, L-shape, or other shape configuration. When using non-bar materials, wall thicknesses should be sufficient to prevent plastic deformation upon splitting impact. In this embodiment, body portion 128E serves as both a fixation portion 104E and as a support of blade portion 102E. In this embodiment, primary blade 118E comprises opposed primary deflector face 138E and secondary deflector face 140E to wedge the wood apart during splitting. Superiorly, the deflector faces narrow and transition into primary edge face 134E and secondary edge face 136E until reaching cut edge 132E. Inferiorly, blade bottom blade surface 236E rests over top face 154E of body portion 128E and is secured in place with welds therebetween. An optional secondary blade 120E is joined, preferably by welding, to a proximal end face of body portion 128E and primary blade 118E. In some embodiments as illustrated here, a bottle opener recess 220E defined by an opener face 219E is provided for the user to open and consume bottled drinks when splitting wood. In this embodiment, bottle open recess 220E is positioned for opening to the internal tube cavity 129E of body portion 128E. Although most embodiments illustrate the cut edge of a primary blade or secondary blade to be generally linear, in alternative embodiments, the cut edge may be concave or convex superiorly.
FIG. 21 illustrates another embodiment of the article of invention. In this embodiment, wood splitter 100F comprises a solid body portion 128F. Here primary blade 118F and optional secondary blade 120F are machined or casted. As illustrated in this embodiment, a blunt sided first bumper 222F and a second bumper 224F may be secured to the side edges of blades to reduce blade exposure. The bumper is sometimes referred to as a log boss or side boss.
FIG. 22-23 illustrates another embodiment of a wood splitter 100G comprising a body portion 128G that is solid and having a blade portion 102G that is at least partially removable. Sloped primary deflector face 138G and secondary deflector face 140G are cut in body portion 128G. A blade interlock 238G mechanism is used to secure a removable edge portion 135G of the blade from blade portion 102G. In this embodiment blade interlock 238G is in the form of a pair of spaced tongues namely first tongue 228G and second tongue 230G extending from blade bottom surface 236G. The first tongue 228G and second tongue 230G are received a complementary first recess 232G and second recess 234G in an operational configuration and the removable aspect may be separated from the blade portion in a storage configuration as illustrated in FIG. 23. Alternatively, the recesses and tongues may be reversed such that the tongues extend from body portion 128G.

A tongue coupler 387CC is fixed to a trailer tongue 383CC and is operable to releasably couple to a hitch ball. In this embodiment (FIG. 83), wood splitter 100CC is secured to trailer frame 384CC using a blade restraint 386CC illustrated here in the form of a pin extending through a body portion 128CC of fixation portion 104CC. The pin is restrained on both a top and bottom end (i.e. bolt head, nut) to retain position. In an operational configuration, wood splitter 100CC is rotated outward from trailer frame 384CC to provide access to it as illustrated in FIG. 83. In a storage configuration, wood splitter 100CC is rotated for storage underneath trailer frame 384CC as illustrated in FIG. 84 thereby minimizing contact by those passing by. In an alternative configuration as illustrated in FIG. 85, fixation portion 104CC of wood splitter 100CC is housed within splitter sleeve 388CC having a form reflective of a hitch receiver. In this embodiment, splitter sleeve 388CC is in the form of a section of square tube secured to a top section of trailer frame 384CC. In preferred embodiments, the square tube is welded or bolted to trailer frame 384CC. The internal dimensions of splitter sleeve 388CC are configured for sliding engagement of a fixation portion 104CC of wood splitter 100CC. Splitter sleeve 388CC may include a pin hole 385CC for securing wood splitter 100CC in place in an operational configuration using a hitch pin 112. In a storage configuration, hitch pin is removed and wood splitter 100CC is slid out from splitter sleeve 388CC and preferably stored.
FIG. 86 represents yet another embodiment of a trailer mounted wood splitter 100DD wherein splitter sleeve 388DD is configured as a bracket for mounting to a trailer frame 384DD having a tongue coupler 387DD. In some embodiments the bracket is permanently fixed such as by welding, and in other embodiments is removable in conjunction with fasteners for example. Squarely configured sleeve walls 416DD define sleeve cavity 414DD which again is sized and shaped for housing wood splitter 100DD therein. In an operational configuration (also known as operational mode), blade portion 102DD is exposed as illustrated in FIG. 86. In a storage configuration (also known as storage mode), wood splitter 100DD is reversed wherein blade portion 102DD is shielded within sleeve cavity 414DD as illustrated in FIG. 87. Hitch pin 112DD may be utilized to secure wood splitter 100DD within splitter sleeve 388DD. One or more bracket fasteners 410DD (i.e. bolt, nut, washers) may be used to secure splitter sleeve 388DD to the trailer, in this case spanning between aligned leg apertures 412DD on first bracket leg 406DD and second bracket leg 408DD. A protectant such as a rubber liner may be used at the internal bracket walls 417DD to minimize abrasion between the bracket and trailer. This removable bracket configuration provides retrofitting to existing trailers and mounting to new trailers without disrupting frame metal or paint.
FIG. 89 illustrates another embodiment of a wood splitter 100EL whereby the wood splitter 100EL has a stem 430EL that is threaded extending from a base surface 344EL. In this embodiment, frame hole 418EL serving to secure stem 430EL therein, extends through a portion of one or more of a trailer frame and a trailer tongue and a trailer bumper. Stem 430EL is seated in frame hole 418EL for operational use with base surface 344EL supported by the respective trailer frame, trailer tongue, or tailer bumper. A hitch ball nut 338EL with hitch ball washer 336EL may be utilized to secure wood splitter 100EL to the trailer frame or trailer tongue. However, in an alternative embodiment, it is unnecessary for stem 430EL to be threaded in which case the user simply drops the post through frame hole 418EL for use, and removes wood splitter 100EL as desired by simply lifting wood splitter 100EL off the trailer frame. In an alternate embodiment, stem 430EL may be secured within the hole of a holed plate 419EL extending fixed or removably fixed from a trailer frame or trailer tongue.
FIGS. 90-93A represents various forms of a wood splitting system that includes a base fastener 420FF having an interactive lock head for quick attachment and detachment of parts to it. As illustrated in FIG. 91, (wherein base fastener 420FF is seated in ball mount hole 458FF) base fastener 420FF comprises a central axis T with a broad beveled boss 426FF sloping towards a superiorly protruding center boss 422FF. Head aperture 424FF extends generally perpendicular through center boss 422FF for housing of release pin 444FF. On center boss 422FF and beveled boss 426FF is male surface 428FF. The underside of center boss 422FF is generally flat with base face 432FF thereon. Stem 430FF extends generally centrally and inferiorly from base face 432FF and may be threaded for fixing to a support structure such as a ball mount (FIG. 91), trailer frame (FIG. 90) or trailer tongue, or indirectly through a complementary bracket attached to these structures or holed plate 419EE. Various sized interchangeable trailer balls such as the 1.875″ ball 454FF and 2″ ball 456FF and 2.3125″ ball (not shown) are currently available as interchangeable kits for use with a variety of trailers. Inclusion of an interchangeable wood splitter 100FF offers an expansion creating a novel interchangeable kit that includes wood splitting capabilities when using base fastener 420FF and a complementary support structure such as those mentioned above (i.e. ball mount, trailer frame, holed plate). Alternatively, wood splitter 100FF may be offered as an accessory to swappable hitch kits. In these embodiments, wood splitter fixation portion 104FF comprises a female cavity 445FF generally complementing the size and shape of base fastener 420FF. In this embodiment, female cavity 445FF comprises a female bevel 448FF leading to a superiorly placed female recess 446FF with female surface 452FF thereon both 448FF and 446FF. Pin aperture 450FF extends generally perpendicular to axis ‘T’ through the body of wood splitter fixation portion 104FF. Distracting release pin 444FF provides the user quick removal of an interchangeable head or blade. To attach wood splitter 100FF, female cavity 445F is aligned along axis ‘T’ above center boss 422FF and lowered such that center boss 422FF is fully seated within female recess 446FF. Head aperture 424FF is aligned with pin aperture 450FF. Release pin 444FF can then be inserted in the pin aperture spanning across both apertures thereby locking wood splitter 100FF thereon. Finger recess 442FF may be present as a depression at the pin aperture. It is recognized that wood splitter 100FF may be used for splitting without release pin 444FF. Other quick release mechanisms known in the art such as bayonet may be substituted for the previously described pin method.
FIG. 93B illustrates yet another embodiment of a wood splitter 100AE configured for use on a trailer frame 384AE or trailer tongue 383AE instead of a hitch receiver 126. In this embodiment, wood splitter 100AE comprising deflector saddle 270AE is a form of wood splitter 100J illustrated previously in FIGS. 31-33. Deflector saddle 270AE, having opposed spaced saddle legs 272AE, is sized for seating a portion of trailer frame 384AE or trailer tongue 383AE therein thereby releasably securing wood splitter 100AE for log splitting impact.
FIG. 93C illustrates yet another embodiment of a wood splitter 100AF configured for use on a trailer frame 384AF or trailer tongue 383AF instead of a hitch receiver 126. In this embodiment, wood splitter 100AF which is a form of wood splitter 100I is secured to trailer frame 384AF by one or more welds 304AF extending between trailer frame 384AF and fixation portion 104AF of wood splitter 100AF. A removable protector such as protective sleeve 254AF with sleeve cavity 256AF form therein is operable to slide over or otherwise be affixed on the blade portion 102AF when the splitter is not in use and removed in an operative mode. Collector 258AF may be placed below wood splitter 100AF to catch kindling as it is split from a log and lumber. Elevator 262AF may be used to tilt collector whereby kindling pieces fall to the side thereby not interrupting the splitting process.
FIGS. 93D-93E illustrates another embodiment of a wood splitter operable to use when seated within a receiver cavity 131 of a hitch receiver. In this embodiment, a ball mount 340AG comprises a fixation portion 104AG and a ball mount tongue 341AG extending from fixation portion 104AG. Ball mount tongue 341AG comprises opposing tongue faces 343AG suitable for mounting a base face 344AG of blade portion 102AG thereon. One or more welds 304AG extend between ball mount tongue 341AG and blade portion 102AG to fix it in place. Weld 304AG may also be used to secure guide portion 106AG to blade portion 102AG in a predetermined position. As recognized here and with a wide variety of other embodiments described herein, a fixed or removable log boss may be positioned to elevate over one end, or both ends of the cut edge. A log boss may be used in conjunction with a guide portion or in the absence of a guide portion.
FIG. 93F illustrates an embodiment of a blade portion 102AH removably seated over a hitch ball 334AH which in turn is mounted to a ball mount 340AH. Note that the ball mount tongue 341AH may be extended various lengths when used in this disclosure. In some forms, a base pod 345Y of a ball mount tongue is generally aligned with a fixation portion (FIG. 73) of the ball mount, whereas in other embodiments the base pod is offset by up to 8 inches or more. FIG. 93F illustrates, for example, an extended length ball mount tongue 341AH that thereby raises the height of blade portion 102AH providing more room for a collector (i.e. 258AF) to be placed below as well as reduced back bending by a user during splitting operations. This is particularly useful on vehicles having lower hitch receivers. In addition, as just one example, FIG. 93F illustrates this style of wood splitter (fitting over a hitch ball 334AH/having a ball space) may also comprise a secondary blade 120AH extending generally perpendicular to primary blade 118AH. This is further illustrated in FIG. 93H. Note in this embodiment that secondary blade 120AH comprises a primary deflector face 138AH that is angled away from secondary deflector face 140AH to produce a wedge effect during splitting. Inset from an outside surface of secondary blade 120AH is secondary blade cavity 548AH (shown here at placement site). FIG. 93J illustrates the same embodiment with one or more secondary blade 120AK which has a primary deflector face 138AK and a secondary deflector face 140AK that are substantially parallel in nature. Note that in preferred blade portions only one secondary blade 120AK is present, however as illustrated here, there may be two secondary blades 120AK opposed to each other.
FIG. 93G illustrates an embodiment of a wood splitter 100AJ whereby a blade lock bolt 460AJ extends through a ball mount hole (note 458AG for example) that extends upwards from its base surface and threads into a threaded female cavity (i.e. note 445LL for example) of the wood splitter. The blade lock bolt 460AJ thereby fixes the wood splitter to the ball mount. Blade lock washer 461AJ may be utilized. Ball mount 340AJ in this embodiment also comprises an extended length ball mount tongue 341AJ.
FIG. 93K illustrates another embodiment of a blade portion 102AL again with a convex cut edge 132AL. Note in this embodiment cut edge 132AL is wider than the inferior base of blade portion 102AL.
FIG. 93L illustrates one embodiment of a blade portion 102AM comprising one or more optional features that may be useful on a variety of embodiments of the invention. Blade portion 102AM is a form of blade portion 102Y illustrated earlier. In some embodiments, base surface 344AM is supported directly against a base pod of a ball mount tongue whereas in other embodiments is supported by superior base face 571AM of hitch ball base 570AM illustrated in FIG. 93M-93N. In some embodiments, base face insets 574AM are inset in base surface 344AM for seating a hitch ball base 570AM having a base profile 572AM that is faceted therein similar to a socket over the head of a bolt. This configuration fixes blade portion 102AM from rotating during use if so desired. In some embodiments, one or more base tabs 573AN (FIG. 93P) extend from base surface 344AM for capture on one or more sides of a ball mount tongue (i.e. 341AG). In some embodiments, ball space 354AM is sized for housing two or more trailer ball sizes (i.e. 1⅞″, 2″, 2 5/16″, 3″). In these cases, a user may use an optional ball space reducer 576AM that provides a ball space 354AM of one diameter when ball space reducer 576AM is absent, and a small ball spacer diameter when ball space reducer 576AM is fitted inside ball space 354AM. In most cases, the ball space reducer removes excess play during use when utilizing a smaller hitch ball. In this embodiment, a ball space reducer 576AM comprises a reducer outer face 579AM defining an outer diameter for fit into ball space 354AM, and a reducer inner face 578AM of a smaller diameter defining a reducer cavity 577AM of a smaller diameter operable to house a smaller hitch ball. In some embodiments, the ball space reducer is biased such that it can be stretched over the surface of a hitch ball.
FIG. 93Q illustrates one embodiment of a blade portion 102AP comprising other features that may be integrated into various embodiments. Note that in this embodiment, primary deflector face 138AP and secondary deflector face 140AP comprise one or more spaced and sloped relief grooves 404AP. In other embodiments, primary deflector face 138AP and secondary deflector face 140AP are substantially smooth. Various apertures or cuts through blade housing 342AP, either closed from or open to an edge may be present as further illustrated this Figure.
FIGS. 93R-93T illustrate an embodiment of a blade portion 102AQ with an internal ball space 354AQ extending from base surface 344AQ whereby the ball space is sized and shaped to house a hitch ball therein. At least one side of blade portion 102AQ comprises a lateral inset 490AQ defining a guide boss 470AG spaced from first guide receiver 108AQ. First guide receiver extends generally horizontally through blade portion 102AQ at a height above where a hitch ball would internally occupy. A cammed tooth 682AQ having a cam aperture receives first guide foot 194AQ therein. A weld 304AQ or other fixation means is used to secure cammed tooth 682AQ at a predetermined position on first guide foot 194AQ. Cammed tooth 682AQ is fixed such that guide portion 106AQ can be folded down in a storage configuration, and held upright in an operational configuration. In an operational configuration, cammed tooth 682AQ is rotated until tooth face 684AQ abuts guide boss 470AQ thereby holding guide surface 188AQ in a predetermined position superior, parallel, and spaced from cut edge 132AQ. Clearance window 680AQ is present if required to provide clearance for tooth face 684AQ when rotating guide portion 106AQ between storage and operational configurations. In some embodiments, clearance is provided by sliding the guide portion laterally first then rotating in which there is no need for a clearance window. In some embodiments, a clipped or pinned internal spring encircles first guide foot 194AQ causing cammed tooth 682AQ to be biased to remain medial in position against guide boss 470AQ.
FIG. 94-104 illustrate a variety of embodiments of wood splitters configured for mounting to a structure such as a ball mount, trailer frame, bumper, or intermediate bracket attached to these structures. FIG. 94 illustrates a wood splitter 100GG having a female cavity 445GG that is threaded through base surface 344GG along an Axis P. Female cavity 445GG is sized to accept blade lock bolt 460GG securely holding the fixation portion to a ball mount 340GG.
Illustrated in FIGS. 95-96 is a similar wood splitter 100GG yet with a stem 430GG which in this case is threaded for capture by hitch ball nut 338GG with hitch ball washer 336GG for securing to a ball mount 340GG through a ball mount hole 458GG. In alternative embodiments, stem 430GG may be utilized without hitch ball nut 338GG and therefore may not require threads in which case wood splitter 100GG utilizes gravity to remain seated during splitting. FIG. 97 illustrates the system shown in FIG. 96 with a guide portion 106GG. Guide portion 106GG comprises a guide wall 186GG with guide surface 188GG formed thereon with the guide wall here in the general shape of a ring which may be fully or only partially enclosed. Guide wall 186GG defines a guide aperture 107GG through which logs may be placed for splitting. Guide wall 186GG is supported by first guide leg 190GG and in some case a second guide leg 192GG as illustrated in earlier embodiments. In this embodiment, first guide leg 190GG comprises a first guide foot 194GG portion. A leg stop 191GG is provided to control the vertical position of the guide portion by abutting against an anchor surface such as a surface of a ball mount 340GG as the leg stop is housed in first guide receiver 108GG. In some embodiments, first guide foot 194GG and first guide receiver 108GG have non-circular profiles to keep guide portion 106GG in a predetermined position over blade portion 102GG.
FIGS. 98-99 illustrates an embodiment of a wood splitter 100HH having a guide portion 106HH extending from a first guide receiver 108HH in the wood splitter. The guide portion 106HH is generally U-shaped. First guide receiver 108HH may assume a variety of forms such as a hole, groove, or a recess. In this embodiment, wood splitter 100HH comprises an upper window 462HH extending laterally or otherwise diametrically through sides of the wood splitter. Here first guide receiver 108HH is located at a superior junction between two sub-primary deflector faces 139HH that at least partially define upper window 462HH. Welds may be utilized to secure a first guide foot 194HH to at least one of sub-primary deflector faces 139HH. In this embodiment, guide portion 106HH comprises first guide leg 190HH extending between first guide foot 194HH and first guide wall 186HH wherein first guide leg 190HH elevates first guide wall 186HH above cut edge 132HH. As illustrated previously in FIG. 48C, first guide wall is positioned generally parallel and laterally spaced from cut edge 132HH for producing a predetermined thickness of kindling from a log. In addition, first guide wall 186HH may also serve as a user guard to protect from direct exposure to blade portion 102HH. It is recognized that first guide foot 194HH may be secured at a variety of positions within upper window 462HH and at a variety of angles. In an alternative embodiment, guide portion 106HH may be generally L shaped with first guide foot 194HH secured (welds, fasteners, captured) to an external wood splitter 100HH surface, a surface of a receiver block (i.e. 568ZZ FIG. 146), or within a first guide receiver within the receiver block.
In alternative embodiments such as illustrated in FIGS. 102 and 104, the first guide foot is configured for seating within a first guide receiver 108KK, 108LL in the form of a bore extending through at least a portion of a wood splitter. Again, the first guide wall position may be fixed by welding. Alternatively, as illustrated in FIG. 102, guide portion 106KK may be pivotable within first guide receiver 108KK wherein a portion of first guide leg 190KK abuts against guide boss 470KK extending from blade portion 102KK in an operational mode and wherein the guide portion 106KK is folded down against primary deflector face 138KK in a storage mode. Alternatively, a set screw or locking pin may be extended through lock port 472KK to interfere with or otherwise clamp guide portion 106KK in a predetermined position. FIG. 104 represents another example of a wood splitter 100LL having a cut edge 132LL that is offset from a central plane of the wood splitter. In addition, primary deflector face 138LL comprises a steeper angulation than secondary deflector face 14OLL. The steeper angulation arrangement is preferred for steering kindling pieces into a collector. An offset cut edge may be utilized in any of the embodiments displayed herein especially those where the blade is rigidly or balanced to less likely cause wobble of the blade portion during impact. For example, the embodiments illustrated in FIGS. 93D, 94, and 95 have a fixed blade portion that will not wobble with impact even in an offset blade configuration.
FIGS. 100-103 illustrates a novel wood splitter 100KK capable of securing to an anchor such as a ball mount tongue by fastener or post in a posted configuration, and alternatively by positioning over a hitch ball in a captured ball configuration. For example, in a posted configuration, FIGS. 100 and 101 illustrates a wood splitter 100JJ having a lower window 464JJ extending through at least one side of blade housing 342JJ forming an inset blade floor 476JJ bounded by a floor stop 478JJ illustrated here in the form of a ridge. In this embodiment, a blade nut 474JJ having a centralized threaded hole is slid into lower window 464JJ and seated against blade floor 476JJ and guided by one or more floor stops 478JJ illustrated here in the form of a ridge. Inset blade floor 476JJ is sized to receive blade nut 474JJ. A threaded blade lock bolt 460JJ engages the threaded hole in blade nut 474JJ securing the assembly to an anchor such as within a ball mount hole of a ball mount. In a captured ball configuration, blade nut 474JJ is removed/absent along with blade lock bolt 460JJ to expose ball space 354JJ. Ball space 354JJ has a diameter sufficient for sliding over a hitch ball thereby utilizing the hitch ball to stabilize wood splitter 100JJ during splitting operations. Removal of captured ball style wood splitters involves the user simply lifting the wood splitter up and off the trailer ball and ball mount (note FIG. 73). FIG. 102 illustrates a second example of a wood splitter 100KK offering both a posted configuration and a captured ball configuration. In a posted configuration, extending into the superior end of ball space 354KK is superior lock recess 482KK having threads complementing extended blade lock bolt 484KK. Extended blade lock bolt 484KK extends through ball space 354KK to engage superior lock recess 482KK to lock wood splitter 100KK to an anchor such as a ball mount or trailer frame. Optional floor plate 480KK comprises a periphery of sufficient size for fit within ball space 354KK and may be positioned in the inferior portion of ball space 354KK to assist positional support of wood splitter 100KK. In a captured ball configuration, extended blade lock bolt 484KK is removed/absent along with floor plate 480KK. Wood splitter 100KK is then set over a ball mount secured hitch ball wherein the hitch ball is captured within ball space 354KK and base surface 344KK rests upon a ball mount surface similar to the embodiment illustrated in FIG. 71. The captured ball configuration is well suited for quick and portable wood splitting due to the simplicity of simply placing the device over a hitch ball of a vehicle.
FIGS. 105-111 illustrate additional forms of wood splitters well suited for a captured ball configuration many of which may be formed by machining or metal casting. These embodiments like all others may include a secondary blade (i.e. FIG. 4). FIGS. 105 and 106 illustrates a wood splitter having a capture face 352MM defining an internal ball space 354MM that is sized and shaped for sliding over and capturing a hitch ball therein. Although the ball space may assume many forms, the ball space 354MM is preferably cylindrical and preferably hemi-spherical at a superior end. At an inferior end, the ball space may broaden in diameter at 486MM to accommodate the flared base often seen with a hitch ball. In some embodiments the ball space may not broaden inferiorly. In this event and depending on the hitch ball style, base surface 344MM will be supported by the ball mount base pod (see 345Y, FIG. 73) or the top surface of the flared base of the hitch ball. One or more flutes 488MM may extend through base surface 344MM and capture face 352MM as a means to reduce weight and material. FIG. 107-108 illustrates yet another embodiment of a wood splitter 100NN again comprising an upper window 462NN that intersects with the superior end of ball space 354NN. At one or more ends of cut edge 132NN, a log boss 492NN may be positioned for quick positioning of a log. The log boss is an enlarged mass extending above the cut edge that a user may use to quickly position a log for splitting while also reducing exposure to the blade. In some embodiments, a log boss is positioned on each end of cut edge 132NN. One or more lateral insets 490NN may be used in the blade housing 342NN to reduce weight and material.
FIG. 109-111 illustrates yet another example of a wood splitter for a captured ball configuration configured to minimize material. In this embodiment, wood splitter 100PP comprises an upper window 462PP, and a lower window 464PP extending through blade housing 342PP. Defined internally in ball space 354PP between upper window 462PP and lower window 464PP is upper chamber 466PP which is preferably positioned such that capture face 352PP is generally aligned with the widest spherical diameter of a hitch ball that would reside therein thereby offering undiminished support. Defined between lower window 464PP and base surface 344PP is lower chamber 468PP preferably sized to capturing a hitch ball base 570AA therein. In some embodiments the lower chamber diameter is sized the same as the upper chamber diameter. In other embodiments, the lower chamber 468PP diameter is larger than the upper chamber 466PP diameter to accommodate hitch balls that have a hitch ball base 570AA of a larger diameter than the hitch ball.
FIGS. 178-183 illustrate yet another example embodiment of a blade portion for a captured ball configuration. Blade portion 102AX comprises a blade housing 342AX extending along Axis Q from a substantially flat base surface 344AX that is aligned in a first plane, Plane V. Primary blade 118AX comprises cut edge 132AX superiorly with opposed primary deflector face 138AX and secondary deflector face 140AX diverging as they extend below thereby creating a wedge. The cut edge may be centered thus intersecting Axis Q or offset from Axis Q. Primary edge face 134AX and secondary edge face 136AX may also be present adjacent the cut edge as well as a secondary blade 120AX if so desired as illustrated previously in FIGS. 93H, 93J, and others. At one or more ends (first end 728AX, second end 730AX) of cut edge 132AX, a log boss 492AX may be positioned for quick positioning of a log and for use as a blade buffer. The log boss is an enlarged mass extending above the cut edge 132AX that a user may use to quickly position a log for splitting while also reducing exposure to the cut edge. As illustrated in FIG. 180, blade portion 102AX is preferably orientated over the hitch ball such that the log boss 492AX is adjacent the user thereby also providing a level of protection between the user and the cut edge 132 AX. Log boss face 495AX is formed thereon the log boss and faces the cut edge. In other embodiments, such as illustrated in FIG. 92, blade portion 102FF has a log boss 492FF orientated opposite the user. In some embodiments, a log boss is positioned on each end of cut edge 132AX. One or more lateral insets 490AX extending towards Axis Q from outer surface 842AX may be positioned in the blade housing 342AX thus reducing weight and material. This embodiment also comprises a circumferential inset 491AX encircling the base of blade portion 102AX. Blade housing 342AX comprises an upper window 462AX defined by sub-primary deflector face 139AX on wedge wall 463AX. The upper window intersects with the superior end of ball space 354AX. Upper window 462AX extends above ball space 354AX and traverses diametrically between outer faces 842AX under primary deflector face 138AX and secondary deflector face 140AX of wedge wall 463AX to lateral sides of the blade housing. The ball space 354AX, substantially defined by capture face 352AX, is generally cylindrical in this embodiment with a substantially vertical elongate axis, but may comprise other profiles such as hexagonal while still functioning to utilize the hitch ball 334AX as a structure for immobilizing the blade portion during use. Ends of cut edge 132AX absent of a log boss may include a sloped relief 836AX. As with all captured ball configurations, preferred embodiments are sized to house within the ball space hitch ball diameters of about 1.875 inch, 2 inch, 2.3125 inch, and 3.0 inch. Most splitting tools disclosed herein including that shown in of FIG. 178 comprise ball spaces having a lateral diameter between 1.875 inches and 3.5 inches and wherein the ball space extends superiorly more than 2.2 inches from base surface 344AX along axis Q.
Some embodiments are sized to work for more than one hitch size. For example, a ball space configured for receiving a 2.3125 inch ball may still work adequately on a 2 inch or 1.875 inch hitch ball without excessive play however a reducer may be used. Note also that the blade housing 342Y in some embodiment is assembled by welds 304Y as illustrated in FIG. 72 from tubing and metal plate, whereas in other embodiments such as blade housing 342AX of FIG. 178 is free of welds and is of a single piece construction except where an optional guide portion is attached to the blade housing. For a single piece blade housing construction, metal casting or forging process may be utilized.
FIGS. 112 through 123 illustrate a select number of embodiments of guide portions. FIGS. 113-115 illustrate a guide portion 106QQ in the form of a plate. In preferred embodiment, guide portion 106QQ is manufactured from sheet metal although other materials such as polymers may be substituted.

First guide receiver 108VV may include a bore for receiving the guide portion therein.
FIG. 127 illustrates a variation of a wood splitter having a guide portion 106VV in the form of a generally straight bar secured at one portion in first guide receiver 108VV. First guide receiver 108VV resides superiorly on receiver block 568VV which extends superiorly above cut edge 132VV from a lateral portion of secondary blade 120VV. In this embodiment, guide wall 186VV with guide surface 188VV thereon is in the form of a bar welded, screwed into, clamped or otherwise fixed to first guide receiver 108VV. First guide receiver 108VV may include a hole or channel for receiving the guide portion therein. In some embodiments, receiver block 568VV may further comprise a sharpened vertical edge whereby wood impacted against the receiver block will be split as it moves down across blade portion 102VV. Likewise, front guide leg 190WW (FIG. 129) may also be sharpened to also assist wood splitting.
FIGS. 128-136 illustrate various forms of wood splitters having a guide portion 106WW switchable between an operational mode (providing guidance through a guide surface to blade cut edge), storage mode (limiting blade exposure by partially shielding cut edge) and an open mode (no guidance with open exposure to blade) in accordance with the disclosed invention. In an open mode as illustrated in FIG. 128, guide wall 186WW is positioned generally perpendicular to cut edge 132WW at a distal end of blade portion 102WW thereby exposing cut edge 132WW. By moving the guide portion 106WW out of the way, the user may use blade portion 102WW for splitting not only smaller kindling pieces, but also to split larger logs into chunks. In a storage mode, guide portion 106WW is rotated such that guide wall 186WW is above and generally parallel with cut edge 132WW thereby minimizing exposure to the cut edge. Second guide foot 196WW may be seated in second guide receiver 110WW which here is in the form of a depression that the foot can elastically snap into and out of Guide portion 106WW rotates about first guide leg 190WW which terminates in first guide foot 194WW which is housed within first guide receiver 108WW bore. First guide receiver 108WW bore is housed in receiver block 568WW which extends behind secondary blade 120WW. A third guide receiver may be located at a position intermediate blade portion 102WW and fixation portion 104WW for receiving second guide foot 196WW when in open mode. Also illustrated in FIG. 128 is logo face 524WW also located intermediate the blade portion 102WW and fixation portion 104WW. Logo face 524WW faces at least partially proximally and is a face comprising no other features aside from trademark information related the product.
FIGS. 131, 134, 137, and 145-147 illustrate further embodiments of wood splitters in accordance with the disclosed invention with guide portions set in an operational mode or configuration. FIGS. 132, 135 and 138, illustrate further embodiments of wood splitters in accordance with the disclosed invention with guide portions set in an open mode or configuration.
Illustrated in FIG. 130 is another embodiment of a wood splitter comprising an L-shaped guide portion 106XX having guide wall 186XX illustrated here in the form of a round rod. Here at least a portion of first guide foot 194XX and in some cases first guide leg 190XX is threaded, however in alternative embodiments the threads are absent. First guide foot 194XX is housed in first guide receiver 108XX of receiver block 568XX extending between an upper prop floor 538XX and a lower prop floor 540XX. First guide receiver 108XX is in the form of a bore along generally vertical axis H. A faceted collar 530XX extends at least partially around first guide foot 194XX and is illustrated here in the form of a square nut. Faceted collar 530XX is supported vertically by upper prop floor 538XX. Faceted collar 530XX comprises at least a first facet 532XX and a second facet 534XX which interface with block face 528XX on block wall 526XX. In this embodiment, first facet 532XX and second facet 534XX are distanced at approximately 90 degrees. Thus open and operational modes are dependent on whether first facet 532XX or second facet 534XX abuts block face 528XX. Faceted collar 530XX which may be threaded, is fixed on first guide foot 194XX at a predetermined position to provide a desired vertical GAP between guide surface 188XX and blade edge 132XX. Welds, adhesives, pins, or other fixation methods may be used to secure the facet collar in place. In this embodiment, faceted collar 530XX is fixed such that the first facet 532XX is parallel to an axis defining guide surface 188XX and second facet 534XX is perpendicular to an axis defining guide surface 188XX. To switch between open and operational modes, the user simply lifts the guide portion enough to unblock faceted collar 530XX and rotate 90 degrees then re-lower into a blocked position. An inferior restraint such as a nut, pin, or clip may be used to releasably retain guide portion 106XX which may be by abutment against lower prop floor 540XX.
Guide portion 106XX illustrated in FIGS. 133-136 operate using a similar function. In this embodiment, guide portion 106XX is in a turret form as noted in FIG. 136. Faceted collar 530XX is a generally circular block with a central turret aperture 542XX extending therethrough. A facet recess 544XX on a radial surface is bounded by a first facet 532XX and a second facet 534XX. Guide wall 186XX with guide surface 188XX thereon is tangent and radially extends from the faceted collar 530XX. A bottom surface of the faceted collar is supported by upper prop floor 538XX. Guide fastener 494XX extends through turret aperture 542XX and is received in a threaded portion of first guide receiver 108XX. Block wall 526XX with block face 528XX thereon extends upward from upper prop floor 538XX and is positioned to travel within facet recess 544XX when guide portion 106XX is moved between modes. Contact between each facet and the block face limits movement of guide portion 106XX.
FIGS. 137-147 illustrate additional examples of embodiments of guide portions within wood splitters in accordance with the disclosed invention. FIG. 137 illustrates an example of a wood splitter 100YY that is monolithic between a fixation portion 104YY and a blade portion 102YY as might be achieved by machining from a single block of metal or casting processes. In this embodiment, a bottle opener is integrated into a proximal end of blade portion 102YY comprising a downwardly extended bottle flange 221YY defining a bottle opener recess 220YY extending upward. The bottle open recess is sufficiently wide to engage a bottle cap therein to wedge it off a bottle for the convenience of the user.
FIG. 140 illustrates an embodiment including optional cavities. A fixation cavity 550YY extends upward from an inferior portion of a wood splitter 100YY into the fixation portion 104YY. Embodiments may also include a primary blade cavity 546YY also extending upward from an inferior portion of wood splitter 100YY but into the primary blade. Some embodiments include a secondary blade cavity 548ZZ extending upward from lower prop floor 540ZZ at an inferior portion of a wood splitter 100ZZ into a secondary blade 120ZZ as illustrated in FIG. 143. One or more cavity dividers 562ZZ may be present to reinforce the cavities.
First guide receiver 108YY, 108ZZ (within receiver block 568YY, 568ZZ) in these embodiments is in the form of a generally vertical bore. Receiver block 568YY, 568ZZ are located intermediately between a fixation portion 104YY, 104ZZ and a blade portion 102YY, 102ZZ. First guide receiver 108YY, 108ZZ is configured to house a first guide foot 194YY, 194ZZ therein. Formed in an upper prop floor 538YY, 538ZZ is block wall 526YY, 526ZZ which is in the form of a channel for cradling various parts of guide portion 106YY, 106ZZ. Offset approximately 90 degrees from the block wall is secondary block wall 527YY, 527ZZ with secondary block face 529YY, 529ZZ thereon which is also in the form of a channel for cradling various parts of guide portion 106YY, 106ZZ as illustrated in the Figures. As illustrated in FIG. 139, the channels formed by the block wall and the secondary block wall intersect at generally 90 degrees in this embodiment but may vary in other embodiments.
Illustrated in FIG. 141 is an alternative embodiment of a guide portion 106YY having a generally circular guide wall 186YY with guide surface 188YY formed thereon. A generally vertical first guide leg 190YY extends substantially perpendicular from generally horizontal guide wall 186YY terminating in a first guide foot 194YY. A prong 558YY, here L-shaped, extends between the first guide leg 190YY and another portion of guide wall 186YY at a distance. First guide foot 194YY is sized to be received and secured in first guide receiver 108YY. Prong 558YY is positioned to reside in the channel formed by secondary block wall 527YY thereby maintaining the height of the guide wall 186YY and its position generally centered over cut edge 132YY. Guide portion 106YY may be formed from a variety of manufacturing techniques including casting and welding of formed rods. As illustrated in previous figures such as FIG. 10A, guide wall 186YY may not be fully enclosed. In alternative embodiments, a second guide leg 192YY may be extended for extra support as illustrated and received in a second guide receiver 110WW such as shown in FIG. 128. The guide illustrated may be inserted or removed by aligning the guide feet to the respective guide receivers and applying an upward or downward force.
FIGS. 144-147 illustrate yet another guide portion 106ZZ also formed in an L shape. In this embodiment, a prong 558ZZ extends from a side of first guide leg 190ZZ. Prong 558ZZ in this embodiment is generally cylindrical and positioned generally perpendicular first guide leg 190ZZ while also being generally parallel with guide wall 186ZZ although distanced inferiorly from it. Welds or fasteners may be used to fix prong 558ZZ to first guide leg 190ZZ. An optional inferior restraint 536ZZ may be utilized at first guide foot 194ZZ to prevent unintended release of the guide portion from first guide receiver 108ZZ.
FIG. 144 also illustrates an alternative form of construction of a wood splitter 100ZZ. In this embodiment, a tubular fixation portion 104ZZ is fixed to a casted or machined blade portion 102ZZ. Tubular fixation portion 104ZZ may be cut from a length of tubular metal stock. Alternatively, bar stock may be used. In preferred forms, the fixation portion has a square profile with a nominal dimension of 1.25 inch×1.25 inch, 2 inch×2 inch, 2.5 inch×2.5 inch, or 3 inch×3 inch for sliding fit into standard hitch receivers. Intermediate cavity 552ZZ is optional, however when present may be sized for the tube or bar stock of fixation portion 104ZZ to slide in and reside partially inside the intermediate cavity 552ZZ. Alternatively, intermediate cavity 552ZZ may be sized small enough such that an end of fixation portion 104ZZ will not fit within intermediate cavity 552ZZ and sits flush with terminal face 554ZZ. One or more positioning pods 556ZZ extending from terminal face 554ZZ may be used to rapidly align blade portion 102ZZ and fixation portion 104ZZ during manufacturing.
Due to variability of wood grains encountered during splitting, kindling pieces may become wedged between secondary blade 120ZZ and receiver block 568ZZ which define wood chute 566ZZ. To minimize wedging, combinations of the following features may be implemented. First, step back 560ZZ is utilized to further distance receiver block 568ZZ from log boss 492ZZ. Secondly, wood chute 566ZZ is wider inferiorly by beveling back the face of receiver block 568ZZ. Third, secondary blade 120ZZ is generally vertical or negatively sloped on the side facing wood chute 566ZZ. In preferred embodiments, wood chute 566ZZ also widens with increasing lateral distance from cut edge 132ZZ. In alternative embodiments, secondary blade 120ZZ is absent.
FIG. 147 illustrates a wood splitter variation having a solid fixation portion which may be in the form of a bar welded to the blade portion or casted as a monolithic part. In this Figure, the bar has a nominal diameter of 1.25″×1.25″. Other embodiments are nominally 2″×2″. Custom diameters and cross-sectional profiles may be utilized.
FIG. 148 illustrates an alternative embodiment of a wood splitter with optional guide portion removed. Note that the body of blade portion 102II as illustrated is curved as is cut edge 132II. In some embodiments this curvature is concave whereas in others the curvature is convex.
FIG. 151-152 illustrates a form of a jack stand having a jack stand base 700AB and a jack stand lift arm 702AB captured within base cavity 701AB of jack stand base 700AB along axis W. A variety of locking mechanisms are utilized in the prior art for locking the overall height of jack stands including but not limited to pinned aligned bores, and toothed jack stand lift arms. The locking mechanisms are immaterial to the wood splitting functions described albeit some are more convenient than others. The embodiment illustrated in the Figures such as FIGS. 151-152 and 154-161 utilizes pinned aligned bores as noted by first jack pin receiver 707AB which extends through base cavity 701AB of jack stand base 700AB. The pinned aligned bores facilitate adjustment and fixation of a jack stand lift arm 702AB or blade arm 704AB within a base cavity 701AB of a jack stand base 700AB. In some embodiments, jack stand base 700AB comprises a broad pod 732AB that is sloped inward superiorly toward a central jack stand base axis (i.e. axis W) at jack neck 734AB. The broad pod 732AB has an inferior base surface 726AB for seating on a ground surface. Base cavity 701AB extends generally vertically through jack neck 734AB and is sized and shaped to slidingly house jack stand lift arm 702AB or jack stand blade arm 704AB therein. First jack pin receiver 707AB is aligned with one of the second jack pin receivers 709AB on the elongate lift trunk 713AB of jack stand lift arm 702AB for a predetermined height then pinned for locking with jack pin 706AB.
Similarly, FIGS. 162-166 illustrate a toothed style jack stand base 700AT configured to adjustably support a toothed jack stand blade arm 704AT or toothed jack stand lift arm 702BI (FIG. 153C). In alternative embodiments, a toothed style jack stand base 700AT is configured to adjustably support a jack stand lift arm 702AT (i.e. 702AT for use with a cover blade such as cover blade 708BW depicted in FIG. 153D, 708BW depicted in 153A and 708BI depicted in FIG. 153C), and in other embodiments the toothed jack stand base supports a modified jack stand lift arm having a blade insert such as 702AU or 702AV as depicted in FIGS. 171-173.
As illustrated in FIG. 153A, a novel cover blade 708AB comprises a blade housing 342AB having a cover blade cavity 710AB extending in from an inferior surface. Cover blade cavity 710AB is sized and shaped to house lift pod 711AB therein. This creates a novel form of jack stand wood splitter 715AB. Cover blade cavity 710AB is defined by capture faces 352AB positioned radially and terminates in base surface 344AB superiorly. Cut edge 132AB is positioned at a superior end with an opposed primary deflector face 138AB and secondary deflector face 140AB angled with respect to each other to create a wedge. Further as illustrated in FIG. 159A, cover blade 708AR may comprise a guide portion 106AR providing a guide wall 186AR with guide surface 188AR thereon spaced superiorly and offset laterally yet generally parallel to cut edge 132AR. In this embodiment, guide portion 106AR is in the form of a U-shaped rod having a first guide foot 194AR housed within a first guide receiver 108AR that extends at least partially through cover blade 708AR and welded, screwed, or otherwise fixed into position. In some embodiments, guide portion 106AR is L-shaped whereas one leg of the L is welded 304AR or otherwise fixed directly to one of first end 728AR and second end 730AR of blade portion 102AR. In some embodiments, one or more ends of cut edge 132AR may terminate in a log boss 492AR (or otherwise known as an enlarged portion 324 in other embodiments) that is elevated above the cut edge. Some embodiments of log splitter 100AR include any one or more of guide portions and log bosses whereas some embodiments include neither. In some embodiments, first guide leg 190AR is resilient such that guide wall 186AR can deflect if necessary when driving a log, in other embodiments first guide leg 190AR is rigid.
FIG. 153B depicts a similar cover blade 708BI with cover blade cavity 710BI defined by capture faces 352BI radially and terminating in base surface 344BI superiorly. As previous for the embodiment of FIG. 151-152, cover blade cavity 710B1 is sized and shaped for housing a lift pod 711 of a jack stand lift arm 702. Opposed primary deflector face 138BI and secondary deflector face 140BI are angled with respect to each other as before for splitting. Some embodiments include an extended collar 729BI which is a portion of cover blade 708BI that extends inferiorly to provide more support as it rests lower on the lift trunk 713BI of a jack stand lift arm 702BI. Extending into the cover blade cavity 710BI are one or more cover restraints 731BI in the form of pins or fasteners such as set screws or thumb screws that are centrally or laterally placed. In the case of set screws for example, they are advanced sufficiently into lift trunk 713BI to prevent removal, limit wobble, or both. In the case of pins, the pins block removal of cover blade 708BI. One or more log boss 492BI may be integrated into the cover blade (one or both lateral ends of the blade), or as illustrated in FIG. 153C, the log boss 492BI is removable by removal of log boss fasteners 493BI. Also depicted in FIG. 153C, is a toothed jack stand lift arm 702BI having lift pod 711BI housed within cover blade cavity 710BI of cover blade 708BI. The embodiment in FIG. 153D depicts a cover blade 708BW much like cover blade 708AB, but having a cover blade cavity 710BW defined by a pair of opposing substantially vertical capture faces whereas the cavity is open at opposing ends. The cavity is bounded superiorly by base surface 344BW. This configuration provides for a cover blade that fits over support surface 765AT of jack stand lift arm 702AT like a saddle and is captured between pod posts 770AT.
In an alternative embodiment, a jack stand lift arm of a jack stand is substituted with a jack stand blade arm as illustrated in FIG. 154-158 to form a novel jack stand wood splitter. In one embodiment, jack stand blade arm 704AB replicates jack stand lift arm 702AB except lift pod 711AB is replaced with blade portion 102AB. Jack stand blade arm 704AB comprises a lift trunk 713AB extending from blade portion 102AB whereas the lift trunk is sized and shaped for being received in base cavity 701AB and fixed using jack pin 706AB. Blade portion 102AB comprises an upward facing cut edge 132AB with opposed primary deflector face 138AB and secondary deflector face 140AB forming a splitting wedge. As illustrated elsewhere, one or more of a; log boss (i.e. 492Q), first bumper (i.e. 222V), and guide portion may be used to guide the log splitting and also minimize cut edge exposure. For example, and as illustrated in FIGS. 156-158, a guide portion may be in the form of a U-shaped rod having a first guide foot 194AQ operable for housing within first guide receiver 108AQ extending through blade portion 102AQ just below cut edge 132AQ. Weld 304Q holds guide portion 106AQ in a designated position. Alternatively, first guide leg 190AQ may be fixed or welded directly to a side of blade portion 102AQ in the absence of first guide foot 194AQ. In some embodiments, a guide boss such as illustrated in FIG. 102 may be present to provide a rotating guide portion as previously described.
In an alternative embodiment, a jack stand blade arm 704AT of a jack stand wood splitter 715AT may be converted for use as a jack stand lift arm by addition of an adaptable lift pod 838BP. As depicted in FIG. 159B, an inferior surface of the adaptable lift pod 838BP has an inferior profile complementary to reside on the blade of jack stand blade arm 704AT. In this embodiment, a substantially V-shaped capture cavity 840BP is defined by inclined V-faces 841BP. The superior facing support surface 765BP of adaptable lift pod 838BP may comprise a variety of profiles but is illustrated here with pod posts 770BP, concave mid-section 766BP, and opposing lift pod flats 768BP. Outer faces 842BP encircle the block body of the adaptable lift pod.
FIGS. 160 and 161 illustrate one embodiment of a guide portion 106AS extending upwards from a jack stand base 700AS. The guide portion 106AS comprises a guide wall 186AS with guide surface 188AS thereon encircling above cut edge 132AS. The guide wall 186AS is supported by a first guide leg 190AS and an opposed second guide leg 192AS that are fixed or releasably fixed to the outer base wall 703AS of jack stand base 700AS. As noted here, outer base wall 703AS of jack stand base 700AS is inwardly sloped on 4 sides from inferior base surface 726AS. First guide leg 190AS and second guide leg 192AS extend upward from respective first guide foot 194AS and second guide foot 196AS to intersect guide wall 186AS thereby supporting it in position. In this embodiment, first guide leg 190AS and second guide leg 192AS diverge as they move superiorly from jack stand base 700AS. Each guide foot may be fixed to outer base wall 703AS using a common fixation such as welding or fasteners. In alternative embodiments, first guide receiver 108AS and second guide receiver 110AS are provided on the outer base wall 703AS to removably house the first guide foot 194AS in the first guide receiver 108AS, and removably fix first the second guide foot 196AS in the second guide receiver 110AS.
FIGS. 162-173 illustrate various forms of jack stand splitters having a toothed jack stand lift arm or toothed jack stand blade arm. For example, the embodiments illustrated in FIGS. 162-166 depict a jack stand base 700AT having a jack neck 734AT extending upward at the jack stand base. A centralized generally vertical elongate base cavity 701AT extends through the jack neck. The base cavity is typically square, rectangular or round to complement the profile of a corresponding lift trunk such as 713AT of a jack stand lift arm 702AT (with lift pod 711AT as illustrated in FIG. 169A), or to complement the profile of a corresponding lift trunk 713AT of a jack stand blade arm 704AT (with blade portion 102AT at a superior end, FIG. 168) for seating of the lift trunk therein. The toothed arms comprise a plurality of trunk teeth 748AT that may be described as pointing downward and separated by tooth gaps 750AT. The tooth gaps are sufficiently wide for cam 738AT interference. The lift trunk may include one or more elongate trunk recesses such as first trunk recess 752AT, and second trunk recess 754AT extending into the trunk from one or more outer trunk surfaces 756AT. The outer base wall 703AT may be interrupted by one or more base windows 758AT extending through the sides (generally rectangular) or bottom (generally square) of the jack stand base 700AT. A U-shaped cam arm 736AT with circular cross sectional profile comprises a cam leg 742AT, a handle leg 744AT, and a stop leg 746AT. A cam 738AT with cam surface 740AT thereon, extends generally perpendicular from the cam leg 742AT. The cam leg pivots through the jack neck 734AT whereby the cam 738AT is positionable for interference mode (FIG. 165) where the cam interferes with a trunk tooth 748AT consequently securing the blade arm or lift pod at a desired height, or positionable for a clearance mode (FIG. 166), where the cam does not interfere with a trunk tooth 748AT allowing consequent adjustment of the lift trunk position. Adjustment of the lift trunk is completed by the user grasping the cam arm 736AT such that the stop leg 746AT is elevated (FIG. 166) thereby moving the cam to the clearance mode, adjusting the height to a desired level, and releasing the cam arm 736AT (FIG. 165) such that cam 738AT moves to an interference mode wherein cam surface 740AT aligns in a tooth gap 750AT and interferes with one trunk tooth 748AT locking the lift trunk in a desired position. In preferred embodiments, the weight of the cam arm 736AT biases the cam 738AT towards the interference mode. In this case, stop leg 746AT abuts outer base wall 703AT or base tab 760AT to hold in interference mode position whereby cam 738AT remains engaged with a desired trunk tooth 748AT. The jack stand blade arm 704AT may absent of a log boss 492AT at either end of the blade, or may include one log boss at first end 728AT, and may also include a second log boss 492AT at a second end 730AT. The first and second log bosses may be manufactured integral to the blade portion or removable such as by the use of fasteners as previously discussed.
FIG. 167-168 illustrate various views of a jack stand blade arm 704AT separated from a jack stand base 700AT. Note lift trunk 713AT may comprise one or more of a first trunk recess 752AT and a second trunk recess 754AT inset from an outer trunk surface 756AT. In some embodiments a hole may extend through the lift trunk of sufficient size to hang the jack stand blade arm 704AT from a hook on a wall.
FIG. 169A illustrates one embodiment of a modified jack stand lift arm 702AT depicted here in the form of having a toothed lift trunk 713AT but may alternatively be in the form of a pinned hole lift trunk (FIG. 152). Integrated into a superior end of jack stand lift arm 702AT is lift pod 711AT having an upward facing support surface 765AT extending between opposed first arm face 772AT and second arm face 774AT. Typically there is a concave shaped mid-section 766AT separating two spaced generally horizontal flats 768AT. In some embodiments, a pair of laterally spaced pod posts 770AT reside adjacent or nearly adjacent first end 728AT and second end 730AT of lift pod 711AT. Extending inferiorly through support surface 765AT is multi-purpose hole 776AT which may take the form of a blind hole extending into lift pod 711AT and in some embodiments into the lift trunk 713AT, or may take the form of a through hole extending all the way through the lift trunk as illustrated in FIG. 169D. Multi-purpose hole 776AT may be unthreaded, partially threaded (FIG. 169D), or fully threaded. If threaded, it is preferable that the threads are at a superior end of the hole. Some embodiments include an interference hole 780AT extending through at least a portion of multi-purpose hole 776AT. Interference hole 780AT is configured to receive a removeable interference key 784 AT that may be threaded into or pushed into interference hole 780AT thereby causing consequent blocking of multi-purpose hole 776AT. Therefore, the interference hole may also include interference threads 782AT. With this configuration, a rod (i.e. sign post, material support stand) may be extended entirely through multi-purpose hole 776AT for resting on a ground surface, or extend partially through multi-purpose hole 776AT until blocked by interference key 784AT, or extend through multi-purpose hole 776AT and locked in place by an interference key 784AT threaded against it. Interference key 784AT may be in the form of, but not limited to, a locking pin or a screw which may include a knobbed end. In some embodiments, the interference key 784AT is removable, thus allowing complete removal of jack stand lift arm 702AT from jack stand base 700AT if so desired.
FIG. 169B-169C depicts a blade portion 102AT configured as a removable blade insert for mating with a modified jack stand lift arm 702AT. In this embodiment, the upward facing side of blade portion 102AT has features described previously in other disclosed blades. The downward facing blade portion 102AT is configured for mating with support surface 765AT. As one skilled in the art would recognize, this downward facing blade portion may assume a variety profiles yet still be supported by support surface 765AT. In a preferred embodiment, downward facing blade portion comprises a convex mid-section 767AT, separating a pair of generally horizontal blade portion flats 769AT. At each end of the downward facing blade portion are pod post seats 786AT shaped to house pod posts 770AT in a mounted configuration. Extending inferiorly from downward facing blade portion is blade anchor 771 AT which in this embodiment is in the form of cylindrical boss sized for sliding fit along axis-WW into multi-purpose hole 776AT for transition from an unmounted to a mounted configuration whereby blade portion 102AT is securely mated with support surface 765AT of lift pod 711AT. In the mounted configuration, wood such as a log placed upright on top of cut edge 132AT and impacted from the top will split as previously illustrated in FIG. 3.
The mating relationship between the blade portion and the lift pod may assume a variety of forms including those illustrated here. For example, FIGS. 170-173 depict various embodiments of modified jack stand lift arms 702AU and 702AV that comprise a blade portion 102AU, 102AV in the form of a removable blade insert 762AU, 762AV. Although illustrated here as toothed jack stand arms, the jack stand arms may alternatively be of an aligned pin hole type. At least a portion of inferior face 764AU and 764AV are configured to complement at least a portion of respective support surfaces 765AU and 765AV on the jack stand arms. In the embodiment of FIG. 170-171, blade portion 1202AU comprises a blade anchor 771AU configured in the shape of a tongue for sliding receipt in boss receiver 788AU which in this embodiment is in the form of a planar recess. The embodiment illustrated in FIGS. 172-173 utilizes a blade anchor 771AV in the form of bulbous shaped tongue for receipt into a bulbous shaped boss receiver 788AV. Note in the FIG. 170 embodiment, the mounted and unmounted configurations are obtained by translation along a generally vertical axis, whereas in the FIG. 172 embodiment, movement between mounted and unmounted configurations are obtained by translation along a generally horizontal axis.
The modified jack stand lift arm with multi-purpose hole is adaptable to perform a wide variety of functions in addition to the log splitting capabilities as will be recognized by those skilled in the art. For example, jack stand base 700AT with jack stand lift arm 702AT equipped with multi-purpose hole 776AT may be used as a pole support such as may be used for portable upright support of signs (FIG. 169G). Here, an inferior end of the sign pole is slid into, or threaded into, multi-purpose hole 776AT. In some embodiments, interference key 784AT is used to stop translation of sign pole 790AT or to clamp against the sign pole to secure it in a predetermined position.
In yet another example, the modified jack stand lift arm with multi-purpose hole is adaptable for use as a material support stand. Cutting boards, pipes, or other material with extended length can be very difficult to balance by one person especially while they simultaneously attempt to perform a mechanical operation such as cutting the material. A material support stand can be very useful to support one end of the elongate material while sawing at an opposing end of the material. A modified jack stand with multi-purpose hole, is utilized to support a material support pole and material support pod thereby eliminating the duplication of material support stand base supports. FIGS. 169E, 169F, and 169H depict examples of various forms of material support stands supportable in the multi-purpose hole of the modified jack stand. For example, FIG. 169E depicts an exploded view of a jack stand base 700AT, jack stand lift arm 702AT, and material support assembly 800BJ. The material support assembly 800BJ comprises an elongate support member 802BJ which may be of a fixed length or of an adjustable length as illustrated in FIG. 169E. Here (although useable in a variety of embodiments), the elongate support member 802BJ comprises an inner rod 804BJ in telescoping relationship with an outer rod 806BJ and a member lock 808BJ for releasably fixing the length relationship between the inner and outer rod. Although an inner rod and outer rod are used here as examples, those skilled in the art will recognize that other profiles of inter-translating elongate support members may be substituted for the rods such as elongate rails. The inferior end of elongate support member 802BJ is threaded 81OBJ in some embodiments for threaded coupling with multi-purpose hole threads 778AT of jack stand lift arm 702AT. In other embodiments, a portion of the material support assembly may be configured for sliding engagement within the multi-purpose hole. At the superior end of elongate support member 802BJ is material support pod 812BJ. The material support pod may be fixedly attached (FIG. 169F), pivotably attached (i.e. hinge), or releasably attached (FIG. 169H, lower left) to a material support assembly 800BJ/BK/BL/BM/BN. The material support pod may be configured for a variety of different uses. For example, in FIGS. 169E and 169F, material support pod 812BJ is configured for rolling support of elongate flat materials such as lumber. It utilizes an elongate roller 814BJ pivoting about a pivot pin 816BJ that is supported by a cradle 818BJ. While supported in the air, a piece of lumber will easily translate as it is moved towards a saw for example. Member lock 808BJ may be used in some configuration to adjust the height of the material support pod, however, in other embodiments the interference key 784AT may be utilized for this. Where height of the support pod is less imperative, the inferior end of the elongate support member 802BJ may be unlocked for resting against a ground surface. FIG. 169H depicts four additional examples of material support assemblies 800BJ/BL/BM/BN. In the BK embodiment, cradle 818BK is configured to hold a pair of roller wheels 815BK in a spaced relationship for cupping the outer surface of an elongate round member such as a pipe therebetween. Due to the rollers, the pipe may be easily rotated during machining operations. Similarly, in the BM embodiment, cradle 818BM is elevated at the end to again cup a round object such as a pipe on a V-shaped platform 823BM. In the BL embodiment, the material support pod 812BL is in the form of a work platform 820BL which in preferred embodiments is generally flat and horizontal although in other embodiments may be angled from horizontal. The platform may serve as an elevated work surface. In some embodiments the work platform is generally round with a raised circumferential fence for securing a paint can to provide an elevated painting experience. In alterative embodiments, a group of 2-4 material support assemblies 800BL, with supporting modified jack stand lift arm 702AT and jack stand base 700AT, are utilized to support a board, a sheet (i.e. plywood), or other support surface (flat or contoured) to create a quickly assembled table surface. Such an arrangement may be useful for a garage sale without the need to purchase a folding table. The BN embodiment illustrates that the material support assembly may be configured for releasable fixation to a material support pod 812BN. In this example, the releasable fixation is by threaded engagement.
FIGS. 169P and 169Q depict yet another embodiment of the use of a modified jack stand, in this case as a portable ski wax station. In this embodiment, a pair of jack stand bases 700AT are spaced on a support surface such as a basement floor. An elongate support member 802BX is supported substantially vertically when housed in the multi-purpose hole 776AT (FIG. 169D) of jack stand lift arm 702AT. Alternatively, elongate support member may use a variety of other support methods to fix to the jack stand lift arm, some of which are illustrated in FIGS. 169I-169N. A ski wax strut 850BX is mounted to the elongate support members. The ski wax strut has a superior facing contoured ski surface 858BX for supporting a ski 852BX to be waxed with bottom side of the ski up, and an inferiorly facing strut bottom 867BX. A binding recess 864BX dips into the ski wax strut 850BX to provide clearance for the ski's binding. A pair of spaced and opposed ski guides 854BX are fixed to each strut side 866BX to maintain ski position therebetween. Extending into the strut bottom 867BX of ski wax strut 850BX are a pair of spaced strut receivers 856BX (one at a tip end 860BX and one at a tail end 862BX) which here are in the form of blind holes of complementary size and shape to receive the superior end of an elongate support member 802BX. This arrangement provides for a quickly assembled/disassembled ski wax station using multi-purpose jack stands.
The elongate support member may use a variety of other support configurations to fix to a jack stand lift arm. Some examples, not all, are illustrated in FIGS. 169I-169N. The embodiments in FIG. 169I-169N illustrates a jack stand base 700AT as described previously in FIGS. 162-164, however the modifications to the jack stand lift arm described here apply also to pinned jack stands like those illustrated in FIG. 152. As illustrated in FIG. 169I, the base of U-shaped support bracket 796BR is fixed to the inferior end of elongate support member 802BR preferably by threaded engagement, welding, or other method known in the art such that when assembled the elongate support member stands substantially vertical. Support bracket 796BR comprises a plurality of fastener holes 792BR extending through the legs of the U-shaped support bracket 796BR and/or horizontal base of the U-shaped support bracket. The legs of the U-shaped support bracket are spaced for sliding fit over the first arm face 772BR and second arm face 774BR of lift pod 711BR. Support fasteners 794BR extend through fastener holes 792BR to clamp the legs of the U-shaped support bracket together or for threading into fastener holes 792BR of lift pod 711BR. As illustrated, the fastener hole 792BR may extend through the base of the U and/or legs of the U. Alternatively, the fastener holes 792BR in the support bracket may be positioned so as to extend across and below the inferior surface of the lift pod thereby clamping the U-shaped support bracket about the lift pod. Alternatively, as illustrated in FIG. 169K, support bracket 796BS is in the form of a substantially horizontal rectangular plate comprising vertical fastener holes 792BS. One or more support fastener 794BS is advanced through fastener holes 792BS of the bracket and threaded into vertical fastener holes 792BS of lift pod 711BS. Again, this may be a threaded engagement with the lift pod or nuts may be utilized on an opposing end of the support fasteners.
FIG. 169L illustrates yet another form of fixation between an elongate support member 802BT and lift pod 711 BT. Here the elongate support member 802BT is fixed to a generally flat and vertically positioned support bracket 796BT preferably by welding 304BT. The support bracket 796BT comprises a plurality of fastener holes extending horizontally through the support bracket and are aligned with complementing fastener holes 792BT in the lift pod for fixation using support fasteners 794BT. Fixation may be by threaded fixation or by use of nuts on opposing ends of the support fasteners. FIG. 169M illustrates use of a support bracket 796BT in the form of a compressive clamping plate. The clamping plate is substantially flat with a vertically arched portion 797BU for housing elongate support member 802BU therein for compressive clamping by advancing support fasteners 794BU within fastener holes 792BU. In yet another example in FIG. 169N, fastener holes 792BV extend through elongate support member 802BV and into lift pod 711BV with clamping by support fasteners 794BV which extend therein using threaded engagement or by use of a nut.
FIG. 169R illustrates perspective views of a size coupler 828BO that may be utilized to couple various sized elongate members such as sign pole 790AT or a material support assembly 800BJ/BL/BM/BN with multi-purpose hole 776AT in the event they are not of compatible sizes. Size coupler 828BO comprises a first coupler end 830BO of a predetermined size and a second coupler end 832BO of different predetermined size. At least one of the first coupler end 830B0 and the second coupler end 832BO are sized for sliding fit into the multi-purpose hole of a jack stand lift arm. One or more of the outer and/or inner surfaces of size coupler 828BO may be threaded for threaded engagement with the multi-purpose hole or with the elongate support member of the material support assembly. In some embodiments, this engagement may occur on an outside surface of the size coupler or on an inside surface of the size coupler.
FIGS. 174-175 depicts an alternative form of jack stand splitter with removable coverblade. In one form, the jack stand base supports cover blade 708AW (a type of blade portion) when used as a wood splitter, and in another form, the coverblade is removed to be used as a jack stand such as to support an RV once parked. In this embodiment, a jack stand base 700AW is substantially pyramid shaped extending upward from inferior base surface 726AW of broad pod 732AW. At each side of the pyramid is an outer base wall 703AW terminating superiorly at a post seat 834AW with a central base cavity 701AW that extends vertically therethrough. Threaded post and nut 725AW (with lever arm 727AW) are removably seated within post seat 834AW when used as a jack stand, however the threaded post and nut 725AW are removed for seating of cover blade 708AW over the superior end of jack stand base 700AW when used as a jack stand splitter. Cover blade 708AW comprises an upward facing cut edge 132AW situated superiorly between a primary deflector face 138AW that diverges inferiorly from a secondary deflector face 140AW to form a wedge for splitting. Blade portions of this disclosure optionally include an opposing primary edge face and secondary edge face extending from the cut edge and between the respective deflector faces such as illustrated in FIG. 175. The edge faces are typically a narrow band of material adjacent the cut edge optimized for cutting into a material and can be the result of blade sharpening. Extending superiorly from one or more ends of cut edge 132AW is an optional log boss 492AW which provides the user a safety buffer from the cut edge. Extending superiorly from an inferior end of cover blade 708AW is a cover blade cavity 710AW which in preferred embodiments comprises a profile complementing the superior end of jack stand base 700AW for fit therein. The cover blade cavity 710AW comprises an inferiorly facing base surface with two pairs of opposed sloped and opposing capture faces 352AW (FIG. 176-177). In preferred embodiments, when cover blade 708AW is seated over the superior end of jack stand base 700AW, the opposing capture faces 352AW are seated against outer base wall 703AW. Similarly, base surface 344AW may be seated against a superior surface of jack stand base 700AW to form a stable and strong wood splitting apparatus.
FIGS. 184-187 illustrate various views of a wood splitter 100AY comprising an ‘I’ shaped fixation portion 104AY for fixation within a hitch receiver 126 of a vehicle (i.e. car, truck, trailer, RV). Extending proximally from the fixation portion 104AY is a blade portion 102AY. The fixation portion comprises; a distal tube wall 184AY at a distal end, a substantially flat top face 154AY opposed to a substantially flat bottom face 156AY, a substantially flat first side face 158AY opposed to a substantially flat second side face 160AY. Together the opposed side faces and opposed top/bottom faces have a width that substantially occupies a trailer hitch receiver when slid into it. As illustrated in various embodiments, a receiver block may be present intermediate the fixation portion and blade portion (i.e. overlapping or extending between). Here, note receiver block 568AY. When present, the receiver block is a mass of material (typically an enlarged mass) that may be used as one or more of: an attachment point for the blade portion, an attachment point for the fixation portion, attachment/housing of a guide portion, as a log boss, and to direct movement of split material. In this embodiment, situated in the receiver block is a first guide receiver 108AY that is positioned upwards (but assumes other positions in other embodiments) for housing a portion of guide portion 106AY. Here, guide portion 106AY is substantially L shaped and in a rod form. One leg of the guide portion is positioned parallel above and spaced laterally from cut edge 132AY. A primary blade 118AY of blade portion 102AY extends proximally parallel to axis M, and an optional secondary blade 120AY extends substantially perpendicular from the primary blade. Extending inferiorly from cut edge 132AY of each blade is a primary deflector face 138AY and a secondary deflector face 140AY as described previously. In this embodiment, the secondary deflector faces are substantially vertical but may assume other inclines, and the primary deflector faces are sloped. If the secondary blade is present, a wood chute 566AY is formed between the secondary blade and the receiver block 568AY. In preferred embodiments, wood chute 566AY widens inferiorly and/or laterally thereby providing low friction escape of wood pieces as they are split and move through the wood chute. Distally adjacent the primary deflector face of primary blade 118AY is an enlarged portion of receiver block 568AY which serves to quickly position wood pieces to be split. In some forms this may be considered a log boss as described earlier. Note in this embodiment that the receiver block 568AY is stepped back distally on the side of the secondary deflector face compared to primary deflector face side thereby providing additional depth to the chute to again provide for easy escape of split wood pieces. A fixation bore 116AY extends across the midsection of the ‘I’ beam and is sized to pass a locking pin to lock the splitter in a hitch receiver.
In this embodiment, one or more primary blade cavities 546AY may extend upwards from a bottom face 156AY of the primary blade 118AY of the blade portion 102AY, and may also extend a second blade cavity 548AY from a bottom face of the secondary blade 120AY. Here a bottle opener recess 220AY with bottle flange 221AY for opening a bottle is formed at a proximal end of the blade portion extending between the adjacent primary blade cavity 546AY and secondary deflector face 140AY of the primary blade 118AY.
FIG. 188 illustrates a wood splitter similar to that described previously but having a log boss 492AZ elevated above the cut edge at a proximal end of the blade portion 102AZ. In some embodiments, a log boss may be used in the absence of a guide rod or vice versa. In some embodiments, both a log boss and a guide rod are used whereas in other embodiments neither is used.
FIG. 189 illustrates a wood splitter similar to the embodiment in FIG. 184 whereas the fixation portion 104BA has a ‘X’ profile instead of an ‘I’ profile.
FIG. 190 illustrates a wood splitter 100EK similar to the embodiment illustrated in FIG. 144 whereas the fixation portion 104EK is in the form of a tube and welded to a blade portion 102EK.
FIG. 191-194 depict a variety of styles of blade plates that can used to form the cut edge of a blade portion. These options may provide more flexibility to utilize sharper or more durable materials than can formed through the casting process without incurring unnecessary expense. FIG. 191 for example, comprises a blade plate 302BC having a superior positioned cut edge 132BC with an opposing primary edge face 134BC and secondary edge face 136BC extending in a wedged configuration from it. A blade plate undercut 303BC extends across the back of the blade plate 302BC with blade clamp holes 145BC extending therethrough for fastening the blade plate 302BC to the body of the blade portion. Integrated with the blade plate and extending perpendicular is secondary blade 120BC. FIG. 193 is a blade plate 302BD sized for capping a secondary blade. It too comprises a blade plate undercut 303BD. FIG. 194 illustrates yet another embodiment of a secondary blade 120BE configured for fastening to a primary blade. It comprises a primary deflector face 138BE and a second deflector face 140BE. One or more fixation pods 305BE are utilized for fixation to a primary blade using welds or fasteners through blade clamp holes 145BE.
FIGS. 195 and 196 illustrate various sized envelope volumes in which selected embodiments of the article of invention may fit. Preferred embodiments of the invention are attractive due at least to their small size, portability and reduced material/weight when compared to wood splitters of the prior art. FIG. 195 for example, illustrates an envelope size in which selected wood splitter embodiments comprising a ball space for fitting over a hitch ball would fit. In this case, an (X, Y, Z) envelope may be (4″×4″×7″), and alternatively (6″×6″×8″), and alternatively (8″×8″×10″). FIG. 196 for example, illustrates an envelope in which selected wood splitter embodiments disclosed herein comprising a fixation portion operable to fit in a receiver cavity of a hitch receiver would fit. In this case, an (X, Y, Z) envelope may be (13″×3.5″×6″), and alternatively (14″×5″×7″), and alternatively (16″×7″×12″). In some cases, removal of the guide portion significantly reduces the size of the envelope needed to house the remaining portions of the wood splitter.
FIGS. 197-201 illustrate yet another embodiment of a wood splitter 100BX. In this embodiment, fixation portion 104BX is equipped for mounting on a common hitch ball such as found on a European style ball mount 340BX. This European style of ball mount is suited for sliding into a hitch receiver of a vehicle and pinned if so desired with hitch pin 112BX. Here the European ball mount is in the form of a substantially square bar but could also be a tube and can assume other profiles besides square as previously discussed. The European ball mount may alternatively use other known fixation mechanisms for attachment to a vehicle known to those skilled in the art.
In this embodiment, European style ball mount 340BX comprises a torso 874BX extending outward and upward from a proximal end. A neck 872BX extends substantially vertical from a proximal end of torso 874BX effectively elevating the wood splitter 100BX above the hitch receiver (i.e. 2-6 inches for example). The neck and bar may be a bar or tube and assume a variety of cross-sectional profiles beside the round profile shown here. At the superior end of neck 872BX is hitch ball 334BX of substantially spherical shape and replicating one of the hitch ball sizes discussed earlier. At a superior end of hitch ball 334BX is first ball flat 870BX, a substantially flattened area.
As illustrated, wood splitter 100BX comprises a blade housing 342BX having an upward facing cut edge 132BX. Extending below the cut edge are opposed primary deflector face 138BX and secondary deflector face 140BX that inferiorly diverge. A respective primary edge face 134BX and secondary edge face 136BX may also be present between the cut edge and deflector faces. Cut edge 132BX is illustrated here as centered over blade housing 342BX but may be offset to one side as previously illustrated in FIG. 104 (also see FIG. 203).
Providing access into ball space 354BX for housing the hitch ball is ball window 884BX. The ball window is defined by ball window face 886BX and is sized and shaped, typically round, for passing through outer face 842BX a hitch ball along the mount-unmount path illustrated in FIG. 200. In addition, generally U-shaped neck collar 880BX defined by collar face 882BX extends into blade housing 342BX. Neck collar 880BX is sized and shaped (vertical channel) to receive neck 872BX therein. Therefore, during mounting of the blade portion 102BX on the hitch ball 334BX, hitch ball 334BX and neck 872BX pass through the ball window and collar until substantially centered in blade housing 342BX. The blade housing is then lowered until the hitch ball 334BX is seated in ball space 354BX against capture face 352BX which defines the substantially spherical ball space. In addition, first ball flat 870BX and a complementing second ball flat 871BX at the superior end of the ball space are seated against each other to provide further stability during splitting operations. Blade portion 102BX in this embodiment comprises a blade portion locking mechanism illustrated here in the form of a neck pin 876BX for removable placement in neck pin hole 878BX. The neck pin hole extends across neck collar 880BX from an outer face 842BX. The neck pin and neck pin hole include cooperating threads in some embodiments. The neck pin hole is positioned such that an inserted neck pin will capture neck 872BX within neck collar 880BX thereby fixing blade portion 102BX upright for splitting purposes. Removing neck pin 876BX provides for removal by lifting the blade portion 102BX such that the hitch ball and neck can escape through the ball window and neck collar. Like other embodiments, a log boss 492BX may be positioned on one end of the cut edge 132BX.
FIGS. 202 and 203 illustrate yet another embodiment of a wood splitter 100BY. The fixation portion 104BY, torso 874BY, and neck 872BY replicate the embodiment of FIG. 197. Fixed (i.e. welded, threaded, pinned, pressed) or removably fixed (i.e. FIG. 92) to the superior end of neck 872BY is blade portion 102BY. At the superior end of blade portion 102BY is upwardly facing cut edge 132BY with one or more pairs of diverging deflector faces and edge faces.
One example of a method of use of a jack stand wood splitter 715AB using a cover blade comprises the following steps. The user obtains a jack stand assembly 716AB and places it on a ground surface. The user then obtains a cover blade 708AB and aligns cover blade cavity 710AB with the top of lift pod 711AB of jack stand lift arm 702AB and lowers the cover blade 708AB until base surface 344AB rests on the superior end of lift pod 711AB. The user then places one end of a log on top of cut edge 132AB and impacts the other end of the log causing it to split with pieces falling to the ground. In a second method in accordance with the FIG. 155 embodiment, the user again obtains a jack stand assembly 716AB and places it on a ground surface. The user removes jack stand lift arm 702AB and substitutes it with jack stand blade arm 704AB and locks into position with jack pin 706AB. The user then places one end of a log on top of cut edge 132AB of jack stand blade arm 704AB and impacts the other end of the log causing it to split with pieces falling to the ground.
