Embodiments of the present invention relate generally to hand tools and more particularly, to hand tools having both rotatable and slideable implements as well as hand tools that are adapted to carry a sharpening tool.
A variety of hand tools have been developed. These hand tools can have a number of different implements depending upon the purpose and desired functionality of the hand tool. The hand tools can include implements that are fixed as well as implements that are actuable or moveable in some manner. With respect to hand tools having implements that are actuable or moveable, the implements can be configured to move in different manners relative to the handle, such as by rotating or folding relative to the handle or by sliding inwardly and outwardly relative to the handle.
Hand tools that include implements that move relative to the handle may be advantageous in that such hand tools can include a number of different implements in a relatively compact package. For example, a pocket knife may include two or more blades that are carried inside a handle for storage and are capable of being selectively opened. In addition to knife blades, folding hand tools can include a variety of other implements, such as a screw driver, an awl, a bottle opener, a can opener, saw, file, etc., in order to add to the versatility and utility of the tools. In addition to implements that fold or rotate relative to the handle, any one or all of the foregoing implements can be designed to slide inwardly and outwardly relative to the handle if so desired.
While hand tools having implements that are adapted to move relative to handle are relatively compact in relation to at least some comparable hand tools in which the implements are fixed, hand tools having implements that fold or slide can still sometimes be bulkier than desired. In this regard, each implement is generally positioned in a side-by-side configuration such that the thickness or width of the hand tool increases with each additional implement. For example, a pocket knife may include a first folding implement adjacent a first side of the handle, a second folding implement adjacent an opposed second side of the handle, and a number of other folding implements positioned side-by-side between the first and second implements. If a hand tool includes implements that slide instead of fold relative to the handle, these sliding implements are also typically positioned in a side-by-side or laterally offset arrangement so as to similarly add to the thickness or width of the hand tool. Thus, it would be desirable to reduce the thickness or width of hand tools while still including the same number and type of implements in order not to unduly limit the versatility of the hand tool.
Hand tools commonly include implements that have cutting edges. For example, knife blades and cutting hooks both have cutting edges. In order to maintain the desired performance of these implements over time, the cutting edges must be sharpened following repeated use of the respective implements. As such, a sharpening tool, such as a honing rod or stone is commonly carried in addition to the hand tool. Thus, when it is believed that a cutting edge is duller than is desired, the sharpening tool is located and the cutting edge is sharpened. Unfortunately, a user of a hand tool is therefore required to carry not only the hand tool, but also a separate sharpening tool, thereby adding to the number of different items with which the user must keep track. In this regard, as the sharpening tool is used only intermittently, the sharpening tool can be misplaced between uses such that the user is forced to expend an inordinate amount of time attempting to locate the sharpening tool. In instances in which the user is in a remote location, such as in the woods or on a lake, the user may be unable to sharpen a dull cutting edge when desired if the user cannot locate the sharpening tool. Thus, it would be desirable to ensure that sharpening tools were more readily accessible to the user of a hand tool.
According to one embodiment, hand tools are provided that include a first, rotatable implement and a second, slideable implement in which a predefined axis along which the second, slideable implement moves and lies within a predetermined plane through which the first rotatable implement rotates. As a result, the hand tool of this embodiment can include first and second implements that need not be positioned in a side-by-side manner, but can, instead, be positioned more compactly so as to move within a common plane. In another embodiment, a hand tool is provided having a handle, at least one implement having a cutting edge, and a sharpening tool carried by the handle and configured to sharpen the cutting edge of the implement. As a result, a user of the hand tool of this embodiment need not carry a separate sharpening tool, since the sharpening tool is already carried by the handle of the hand tool so as to be available upon demand.
In one embodiment, a hand tool includes the handle, a first implement, such as a knife blade, rotatably connected to the handle and a second implement, such as a cutting hook, slideably connected to the handle. The first implement is configured to move through and define a predetermined plane during rotation of the first implement relative to the handle. Similarly, the second implement is configured to move along a predefined axis during the slideable extension of the second implement relative to the handle. As noted above, the first and second implements are further configured such that the predefined axis along which the second implement moves lies within the predetermined plane through which the first implement moves.
The second implement may be configured to slide between first and second positions with the second implement being at least partially disposed within the handle in the first position, but extending outwardly from the handle in the second position. Additionally, the first implement may be configured to rotate between first and second positions with the first implement being at least partially disposed within the handle in the first position, but extending outwardly from the handle in the second position. In one embodiment, the first and second implements are configured to extend outwardly from the handle in opposite directions in their respective second positions.
The hand tool may also include a catch disposed within the handle and configured to engage the second implement in the first and second positions. In this regard, the second implement may define first and second recesses with the catch engaging the first and second recesses in the first and second positions, respectively.
In another embodiment, the hand tool includes a handle and at least one implement connected to and configured to extend outwardly from the handle. The implement includes a cutting edge. The hand tool of this embodiment also includes a sharpening tool carried by the handle and configured to sharpen the cutting edge of the implement.
In respect to the manner in which the sharpening tool is carried by the handle, the handle can define a recess for receiving the sharpening tool. In this regard, the recess defined by the handle may be configured to frictionally engage the sharpening tool. In one embodiment, the sharpening tool includes a honing rod with the recess defined by the handle including a groove for receiving the honing rod. The groove may open toward one end of the handle to permit the honing rod to be slideably inserted and removed from the groove.
In addition to the honing rod, the sharpening tool can include a sleeve for covering the honing rod. Additionally, the sharpening tool can include a handle at one end of the honing rod. The handle, in turn, may include an engagement feature extending outwardly therefrom for frictionally engaging the recess defined by the handle.

The present invention now will be described more fully hereinafter with reference to the accompanying drawings in which some but not all embodiments of the invention are shown. Indeed, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Embodiments of the present invention provide a hand tool that includes a handle and one or more implements. An implement, as used herein, may include a wide variety of tools or blades, including, but not limited to straight or curved knife blades, serrated blades, cutting hooks, screw drivers, awls, bottle openers, can openers, saws, files, or razors. For example purposes only and as shown in
In general, the handle 16 is sized and shaped so as to be readily grasped by a user. The handle 16 may include a first scale, referred to herein for descriptive purposes only as the front scale 18, and a second scale, referred to herein for descriptive purposes only as the back scale 20. As best seen in
The outer facing sides of the scales may define a number of aesthetic or functional features. In the illustrated embodiment, for example, the scales 18, 20 define a notch 32 positioned to receive the index finger of the user as well as a smoothly curved portion 33 extending generally rearwardly from the notch 32 for permitting the other fingers of the user to wrap thereabout. The outer facing sides 26, 28 may also include one or more raised and/or angled surfaces for aesthetics or functional purposes. In yet another example, the outer facing sides may also include textured or non-stick coated surfaces to help strengthen a user's grip of the handle.
The area between the inner facing sides 22, 24 of the scales generally define an interior cavity 30 of the handle 16. The interior cavity 30 may be shaped and dimensioned for receiving at least a portion of one or more of the implements 12, 14. For example, as shown in the illustrated embodiment, the first implement 12 may be rotatably connected between the front and back scales 18, 20 proximate to a first end 34 of the handle. The first implement 12 may rotate in a predetermined plane from a first position, referred to herein for descriptive purposes only as the extended position, to a second position, referred to herein for descriptive purposes only as the retracted position. As shown in
Also, as shown in the illustrated embodiment, the second implement 14 may be slidably connected between the front and back scales 18, 20. The second implement 14 may slide along a predetermined axis between a first position, referred to herein for descriptive purposes only as the extended position, and a second position, referred to herein for descriptive purposes only as the retracted position. As shown in
The implements may be connected to and supported by the handle by a variety of mechanisms or configurations. For example, according to the illustrated embodiment and as best seen in
As best seen in
The back plate 40 is adjacent the inner facing side 24 of the back scale. More specifically, the inner facing side 24 of the back scale may define a recessed area for receiving the back plate 40. The back plate 40 defines a number of apertures for receiving pins extending from other components and fasteners used to hold the front and back scales together. The back plate also defines an opening through which a second spring arm 50 extends. The second spring arm 50 extends from a supported end 51 to a distal and unsupported end 52.
The plates may be made from a variety of materials and methods. For example, the plates may be made from metal through a stamping process. In the illustrated embodiment, the plates are held in place by the recessed areas, fasteners, and the other components. The plates may also be attached to the scales by an adhesive or by other means.
The first implement 12 may be rotatably supported between the plates 38, 40 near the first end 34 of the handle. For example, the hand tool 10 may include a first spacer 54, a first fastener 56, a second fastener 58, first washer 64, and a second washer 65. The first spacer 54 may define a threaded interior surface and an outer cylindrical surface. The first spacer supports the first implement 12, such that the first implement 12 is rotatable about the first spacer 54 between the retracted and extended positions within a predetermined plane. More specifically, the first spacer 54 extends through the front scale 18 and the front plate 38 and through an aperture 60 defined in the first implement 12 to the back plate 40. The first fastener 56 extends through the first washer 64 and engages the threaded interior surface of the first spacer 54. The second fastener 58 extends through the second washer 65, the back scale 20 and the back plate 40 and engages the threaded interior surface of the first spacer 54.
The hand tool 10 may include another pair of washers 62 between the first implement 12 and the plates 38, 40 to increase the bearing surfaces of the first implement and help protect the surfaces of the first implement and the plates as the first implement rotates. For example, the washers may be formed of a plastic with low surface resistance.
As best seen in
The first implement 12 may also be lockable in one or both positions. For example, in the illustrated embodiment and as shown in
The locking lever 42 may be moved between the locked and released positions by engaging the second end 73 of the lever. The lever 42 may be accessible to a user through another notch 82 defined by the top outer edges of the front and back scales 18, 20, as best seen in
The second implement 14 may be slideably supported between the plates 38, 40 and/or scales 18, 20 opposite the first implement 12 along a predetermined axis. For example according to the illustrated embodiment of
The stem 90 defines a second slot 91 that extends along the length of the stem 90 and the length handle 16. The hand tool 10 may further include a third fastener 94 and fourth fastener 96. The third fastener 94 may include head and a spacer end that defines an outer cylindrical surface and an interior threaded surface. The fourth fastener 96 may include a head and a threaded portion. The third fastener 94 may extend through the front scale 18, front plate 38, and the second slot 91 defined by the stem to the back plate 40. The fourth fastener 96 may extend through the back scale 20, back plate 40, and engage the interior threaded surface of the third fastener 94. The stem 90 may also include a pin that corresponds with the first slot 48 defined by the front plate 38 such that the pin slides along the first slot 48 when the second implement 14 is sliding. The scales 18, 20, plates 38, 40, the pin and first slot 48, and the second slot 91 and the spacer end of the third fastener 94 facilitate the sliding of the second implement 14 along the length of the handle 16. The hand tool 10 may also include another spacer 100 that extends between the plates 38, 40 and is contained within the second slot 91 to further facilitate the sliding of the second implement 14. For example, the third and fourth fasteners 94, 96 may extend through the spacer 100 such that the spacer remains substantially stationary as the second implement 14 slides The second implement 14 may also include a serrated portion 102 on an outer edge 104 to help urge the second implement 14 outward or inward during movement. The outer edge 104 extends beyond the handle 16 to allow the outer edge 104 including the serrated portion 102 to be accessible to the operator when the second implement 14 is in the retracted position, as seen in
The hand tool 10 may further have one or more catches to encourage the second implement to remain in one or more of the extracted or retracted positions. For example, according to the illustrated embodiment, the hand tool includes the first spring arm 44 and the spring support 46. The spring support 46 is connected between the two plates 38, 40 by one or more pins on both ends, such that the spring support 46 is inhibited from moving relative to the plates 38, 40. As shown in
The front and back scales of the handle may further be connected to each other by a third set of fasteners near the second end 36 of the handle. For example, the hand tool 10 may further include a fifth fastener 130, a sixth fastener 132, and a third spacer 134. The third spacer 134 generally extends from the front scale 18 to the back scale 20. The third spacer defines an interior threaded surface and a cylindrical outer surface. The fifth fastener 130 extends through the front scale 18 and engages the interior threaded surface of the third spacer 134. Similarly, the sixth fastener 132 extends through the back scale 20 and engages the interior threaded surface of the third spacer 134.
In the illustrated embodiment, the third spacer 134 may function as a stop for the first implement 12 when the first implement is rotated into the retracted position. The cylindrical outer surface of the third spacer 134 may be lined or coated with a shock absorbing material, such as rubber, in order to help protect the edge of first implement 12 when it contacts the third spacer 134.
As stated above the hand tool may include additional implements that are fixed, rotatable, or slideable relative to the handle. Furthermore, the hand tool may include one or more instruments. In general as used herein an implement is a tool or blade that is configured to remain attached to the handle during operations, while an instrument is a tool or blade that is configured to be removed from the handle of the hand tool during operations. For example and not as a limitation, the instrument or instruments may be a sharpening tool, a screwdriver, a wrench, or tweezers.
According to the illustrated embodiment and as best seen in
The location and size of the groove may vary. For example, it may be defined between the plates or by both plates. The groove may also be shaped to only hold a portion of the sharpening tool. Also, instead of sliding the sharpening tool in and out of the groove, the groove and sharpening tool may be adapted for a snap-fit configuration, where the sharpening tool is snapped into the groove from the side of the groove instead of from sliding in from an end of the groove. Also, although described as a groove, the tool handle may have any shaped recessed area for holding or containing the sharpening tool or other instrument.
