BACKGROUND OF THE INVENTION

1. Field of the Invention

The inventions disclosed and taught herein relate generally to vacuum wand and wand extension storage assemblies on a vacuum appliance, and more specifically are related to vacuum extension wand storage assemblies for use with a vacuum appliance so as to allow for storage of one or more vacuum wands or similar vacuum accessories under a vacuum's debris collection drum in a securable and readily detachable manner.

2. Description of the Related Art

Vacuum appliances capable of picking up both wet and dry material, commonly referred to as wet/dry vacuums or wet/dry vacs, are often used in workshops and other environments where both wet and dry debris can accumulate. Wet/dry vacuum appliances conventionally consist of a collection canister or drum, and a power head fitted to the top of the drum, and within which a motor and impeller assembly is mounted. The motor and impeller assembly creates a suction within the drum, such that solid and/or liquid debris is drawn in to the drum through an air inlet to which a flexible hose can be attached. A filter within the drum prevents incoming debris from escaping from the drum while allowing filtered air to escape. Any liquid drawn into the drum is diffused and accumulates on the bottom of the drum. The drum typically includes a drain opening that is stopped by a plug or threaded cap, so that a user can remove the cap to drain accumulated liquid from the drum. Vacuums may include holders for storing accessories, such as brushes, crevice tools, extension wands, end fitting, etc. In some examples, the holders are permanently secured to the vacuum and cannot be readily removed. In other examples, the holders are portable and detachable members that are independent of the vacuum. Detachable holders are especially desirable, for example, when an operator empties debris from a drum of a wet/dry vacuum.

One of the foremost attributes of vacuum cleaners, particularly wet/dry vacuum cleaners, is the fact that they are both user friendly and versatile. They provide thorough and efficient cleaning of both dry and wet debris, and generally may be easily directed and controlled to clean the work area. In order to add to the versatility of vacuum appliances, such as wet/dry vacuum cleaners, many vacuum appliances are now equipped with various tools and cleaning accessories such as extension hoses, wands, upholstery brushes, squeegee tools, and crevice cleaning tools. These tools and accessories allow the vacuum appliance to be used to complete a variety of special cleaning applications such as the cleaning of furniture and draperies and hard-to-reach areas where the size of the vacuum cleaner would otherwise prevent cleaning due to size and weight concerns.

As indicated above, user convenience considerations require that the tools and accessories, such as the vacuum hose extension wands, be quickly and conveniently available to the vacuum cleaner operator. Accordingly, many vacuum appliances are provided with tool storage compartments that are generally built in to the power head assembly, or in to the caster housings for the wheels of the vacuum. Still others are provided with removable caddies that hold the various tools and cleaning accessories, but with no particular securement means. Such caddies may be mounted and carried on the housing of the upright vacuum cleaner or removed and stored at a remote location as desired by the operator. Many recent versions of such vacuum cleaners have included tool holder accessories mounted to the outer wall of the drum itself. Such tool holders can be provided in a number of forms to enable hoses, nozzles, brushes, and other vacuum cleaner accessories to be stored or mounted thereto when not in use. For example, such tool holders can extend outwardly from the side wall of the collection drum and include a number of outwardly or upwardly extending appendages which are sized to receive each of the tools in a frictional arrangement.

Unfortunately, existing detachable holders for accessories on wet/dry vacuums have some disadvantages. Some existing detachable holders slip fit onto the vacuum and do not positively latch or attach to a feature on the vacuum. With such a slip fit, the detachable holder can work loose and possibly fall off during use or movement of the vacuum. In addition, some existing detachable holders hang on posts or tabs attached to the vacuum. These detachable holders are not fully supported by the posts or tabs and may spill the accessories or catch on stairs when the vacuum is hauled, moved or lifted.

An example of such an accessory tool holder, or caddy as it is sometimes termed, is described in U.S. Pat. No. 5,528,794, which describes a utility vacuum cleaner tool caddy for utility vacuum cleaner drums as well as an axle-less wheel mount. The tool caddy has rear and front wheels with integral rear and front bumpers at least partially overlying the rear and front wheels. This provides a wider/larger wheel base/caddy which increases the stability of the utility vacuum cleaner during movement. The rear bumper is also provided with a plurality of spaced openings for receiving a corresponding number of vacuum tools which are stored in an out-of-the-way location when moving or storing the utility vacuum cleaner. Additionally, the wheel support increases the load capacity while improving the overall look and appearance of the base unit or tool caddy.

U.S. Pat. No. 5,943,731 describes an accessory holder for a vacuum cleaner having a base member for supporting a plurality of vacuum accessories. The base member has a pair of arms for attaching the holder to a support structure on the vacuum cleaner. The arms include a tapered wedge projecting from the base member for intermeshing with a tapered channel in the support structure to provide a frictional retaining attachment of the base member to the support structure. The holder further includes a cradle portion extending from the base member for selectively engaging a portion of the vacuum cleaner wand to detachably secure the holder to the wand.

U.S. Pat. No. 7,159,272 provides a holder for storing accessories on a wet/dry vacuum. The holder securely attaches to the vacuum and readily detaches therefrom. The detachable holder may be detached with the accessories. While an operator dumps debris out of the drum of the vacuum, detaching the holder prevents the accessories from being inadvertently spilled out of or discarded from the holder. The detachable accessory holder fully secures to a bracket attached to the vacuum. The secure attachment prevents the holder from falling off or tipping on the vacuum. To attach the holder to the bracket and vacuum, grooves on the holder are set on to an axle of the vacuum. As the holder is pivoted about the axle, tabs and a latch on the holder engage slots and a step on the bracket. To remove the holder, the operator presses on the latch and lifts the holder from the bracket and the appliance.

Other vacuum tool accessory holders use the wheel casters of the vacuum cleaner as the means by which the vacuum tools and accessories are stored when not in use. Examples of this approach include those disclosed in U.S. Pat. No. 4,827,564 and U.S. Pat. No. 5,924,165, which describe caster foot assemblies for use with an appliance such as a wet/dry vacuum. The caster foot assembly include a body, at least one vacuum accessory securing post in the body, and a caster receptacle in the body, wherein the securing post and the caster receptacle vertically overlap within the body to lower the center of gravity of the appliance.

All of these approaches to tool accessory storage, however, can have issues with the storage of the vacuum hose extension wands, which due to their length and rigidity can be cumbersome to secure in an upright manner in a caddy or on a caster, particularly when the user wishes to transport, lift or store the vacuum in a confined space.

The inventions disclosed and taught herein are directed to improved storage assemblies for use with wet/dry vacuum appliances so as to more efficiently store and secure vacuum wand extensions under the vacuum debris collection drum, thereby providing unwanted dislodgment of the wands when they are stored but not in use, and/or to prevent accidental loss of the wands when they are not in use.

Applicants have created improved storage assemblies for use with wet/dry vacuum appliances so as to more efficiently store and secure vacuum wand extensions under the vacuum debris collection drum, thereby providing unwanted dislodgment of the wands when they are stored but not in use, and/or to prevent accidental loss of the wands when they are not in use. In particular, the described wand storage assembly combines a channeled, shaped surface in the bottom face of the vacuum debris collection drum and a pass-through opening within the accessory storage assembly that is attached to the collection drum. In order to further improve the storage system, a drum-attached wand stop is included in an orientation opposite the accessory storage assembly in order to secure the wand's positions in the event of transportation, lifting, and product storage, thereby preventing the wands from being lost or misplaced.

Referring now to the drawings, FIG. 1 illustrates a front perspective view of a vacuum appliance in accordance with aspects of the present disclosure. FIG. 2 illustrates a rear perspective view of the vacuum appliance of FIG. 1. FIG. 3 illustrates a bottom view of the vacuum appliance of FIG. 1. These figures will now be discussed in conjunction with each other. With specific reference to FIG. 1, a vacuum cleaner constructed in accordance with the teachings of the disclosure is generally referred to by reference numeral 20. While the disclosure and the drawings depict a wet-dry vacuum cleaner of the type adapted to pick up both dry and/or liquid debris, it is to be understood that the teachings of the disclosure can be used in conjunction with other types of vacuum cleaners as well as other types of appliances and tools wherein it is desirable to mount one accessory onto another in a stable and secure fashion. Vacuum 20 as shown in the figures accompanying this disclosure is of a relatively small capacity, having a collection drum volume of approximately 2.5 gallons (although it is understood that a vacuum in accordance with the present disclosure may be larger or smaller than 2.5 gallons in drum capacity). Additionally, while the vacuum cleaner 20 illustrated herein has a generally oblong, non-cylindrical shape, it will be appreciated that the assemblies for extension wand storage described herein may be used in conjunction with vacuum cleaners and wet/dry vacuum appliances having a cylindrical collection drum with a generally circular cross-section, as appropriate.

With continued reference to FIGS. 1-3, the vacuum cleaner 20 is shown to comprise a collection drum 22 having a bottom 24 from which sides 26 extend up, defining an open top (not shown). Drum 22 may be made of blow-molded or extruded plastic, such as polyethylene, polypropylene, or the like. A lid, or power head 28 is removably secured over the top of the collection drum 22 via latches 30 to the side wall 26, so as to close off the open top when desired. Power head 28 houses a motor and impeller assembly for generating the necessary pressure differential within the tank 22 to create the vacuum (the vacuum pressure), and is connected to a filter cage and float assembly (not shown) as appropriate for wet debris pickup, such filter cage being fastened to the power head 28 and extending downwardly into the interior 21 of the drum, or upwardly into the power head, as appropriate. An air inlet 32 is formed in the front portion of the collection drum 22, and is shaped so as to allow the attachment of a flexible vacuum hose 18 via a locking, friction-fit, or other suitable securement means, such as the attachment used with the TUG-A-LONG® locking hose assembly (available from Emerson Professional Tools, St. Louis, Mo.). Optionally, and depending upon the configuration and size of the vacuum appliance 20, the air inlet 32 may be formed in the front portion of the power head 28. As shown in the Figures, power head 28 also includes a handle 29 having power actuating switch 25, and a power cord 27 for powering the vacuum appliance via a typical electrical outlet. The power actuating switch 25 is preferably located towards the front of the handle 29, so that the switch 25 may be conveniently reached with a users thumb or finger while holding the vacuum 20 by the handle 29. The tank 22 may further include a plurality of wheels 34 and casters 36, in any appropriate combination (e.g., two rear wheels and one front caster is illustrated in the present figures), to facilitate movement of the vacuum cleaner 20.

FIGS. 1-3 also illustrate optional notched spaces 31 and 31′ formed in handle 29, so that power cord 27 can be wrapped around handle 29 during transport. The figures also illustrate grooves 23 formed in the sides of power head 28, generally in the region of the interface of the collection drum 22 and the power head 28 and parallel to the longitudinal axis of the vacuum 20 (e.g., parallel to the orientation of the handle 29), so that the vacuum hose 18 can be wrapped around vacuum 20 during storage and transport.

FIGS. 1-3 further illustrate the wand accessory storage assembly 40 in accordance with the present disclosure, for use in conveniently storing vacuum hose extension wands 38 when they are not in use. Extension wands 38 are illustrated to be generally cylindrical in shape so as to be generally tubular, and having a front end 37 and a rear end 39 spaced apart longitudinally along a central longitudinal axis of the wand. While the wands 38 are shown to be cylindrical, it will be appreciated that the wands, and the associated receptacles described herein, may be of any shape that is appropriate. The wand accessory storage assembly 40 is secured to the bottom face 24 of the collection drum 22, and includes a front wand securing assembly 50, and a rear wand securing assembly 70, the latter of which includes a rear vacuum accessory caddy, or receptacle having an open side toward the rear peripheral wall of drum 22, and the remaining peripheral walls 72 of the receptacle 70 completing the enclosure of the sides of the receptacle when the receptacle and rear wand securing assembly 70 are installed on the vacuum 20. A plurality of vacuum tools and accessories, such as nozzles, squeegees, and brushes, can be stored in the rear receptacle 70 when they are not in use.

Turning now to FIGS. 4-10, details of the wand storage assembly 40 are provided. As described above, the wand storage assembly 40 comprises two sections, a front wand securing assembly 50, and a rear wand securing assembly 70, the latter of which is tied to a tool storage receptacle 48. As can be seen most clearly in FIG. 4 and FIG. 10, the rear vacuum extension wand securement assembly 70 is spaced longitudinally apart, and opposite from, the front wand securement assembly 50. Both the front and rear wand securing assemblies are attached directly, via screws or other securement means, to the bottom face 24 of the collection drum 22. As seen in the detail of FIG. 4 and FIG. 5, two integral, shaped (in this case, arched) channels 41, 43 are formed within the bottom face of drum 22, to allow for a more direct pass-through for the wands 38 when they are inserted from the rear assembly 70 towards front securing assembly 50.

FIG. 4 illustrates a side view of an exemplary vacuum appliance 20, showing a partial cut-away cross section of the drum 22 so as to illustrate added details of the drum and extension wand securement assembly 40. As can be seen therein, the bottom face 24 of the collection drum 22 can include at least one front indented receptacle 92 and spaced apart rear indented receptacles 96 formed or molded into the bottom of the drum itself and extending upwardly into the interior 21 of the drum. Caster mounting shank 94 associated with a front caster 36 is installed in the opening 92 in bottom of the drum 22, thus enabling the attachment of the caster(s) 36 beneath the collection drum. Securement prongs 53 on rear securement assembly 70 may be inserted within the indented receptacles 96 in the bottom face of the drum 22 so as to engage the rear securement assembly 70 with the drum 22, at least in part. Other indented receptacles and securement prongs on these components may be included within the overall drum design, as appropriate, depending upon the size and attachment requirements of the assembly 70 (e.g., additional receptacles may be formed high up the interior 21 of the drum). Other suitable receptacles and engaging means may be substituted for either holding the casters or securing at least a part of the rear securement assembly 70 in the receptacles beneath the drum 22. As also shown in FIG. 4, the bottom of the drum 22 may further include one or more raised regions 90 extending upwardly into the interior of the drum, shaped to coincide with the shaped channels 41, 43 formed into the bottom of the collection drum.

As further shown in the cut-away section of FIG. 4, the vacuum air inlet 32 includes an aperture extending from the exterior to the interior 21 of the collection drum. A cylinder 98 circumscribes the aperture and extends substantially orthogonally to the front wall of the drum 22. The cylinder 98 extends from the exterior of the drum inward in a substantially orthogonal direction before curving radially inwardly and terminating in a deflector 100. An outlet 102 is provided in a side wall of the cylinder 98 as shown in FIG. 4. As a result of the curvilinear or angled shape of the deflector 100, a fluid stream directed in through the aperture 96 via inlet 32 is deflected in the direction of the deflector 100 toward the outlet 102. Therefore, depending upon the position of the deflector 100, the direction of the exiting fluid stream will be affected.

More specifically, as depicted in FIG. 4, the deflector 100 may be directed downwardly such that the outlet 102 opens downwardly into the collection drum 22. Such a position for the deflector 100 would be appropriate when the vacuum cleaner 20 is used in conjunction with a vacuum bag, and/or when dry materials are being vacuumed. Conversely, while not specifically shown in the figures, the deflector 100 may be positioned upwardly such that the outlet 102 opens upwardly within the interior 21 of drum 22 and proximate a downwardly depending shroud (not shown) of the bottom face of the power head 28. Such would be the position for vacuuming wet materials. In so doing, the liquid entering through the vacuum air inlet 32 would be directed by the deflector 100 toward the shroud and against which the liquid would be imparted to thereby slow the liquid before dropping into the drum 22. As a result, splashing of the liquid is lessened and the likelihood of splashing liquid being drawn into the motor/impeller unit and expelled through the blow outlet, or any other outlet provided within the vacuum cleaner 20, is abated.

As illustrated in FIGS. 5-7, the front wand securement stop assembly 50 is located on the bottom 24 or lower wall region of the collection drum 22 generally opposite the rear securement assembly 70, preferably below the section of the drum having the inlet 32. The stop assembly 50 preferably includes a wand positioning and retaining stop, such as a pinch finger 46 as shown in FIG. 7, so as to securely retain the extension wand 38 in place once it has been inserted into the securement assembly 40. Details of the front wand securement stop assembly 50 are illustrated in FIG. 5, FIG. 6. and FIG. 7. Stop assembly 50 includes a front end 52, a spaced apart back edge 54, and side regions substantially perpendicular thereto comprising shaped slots 60, 62 forming the bottom of the side regions, retaining ledges 64, 66 in front of and slightly above the shaped slots, and wand stops 59 at the front edge of the ledges, the wand stops 59 being substantially perpendicular to ledges 64, 66, and substantially parallel with the front end 52 of the assembly 50, as well as the wall 26 of the collection drum 22. Extending inward (toward the back edge 54) from the wand stops 59 are pinch fingers 56, 58 which serve to securely retain the front ends 37 of the wands 38 in place. Pinch fingers 56, 58 extend generally parallel with the bottom 21 of the collection drum, and generally parallel to the slots 60, 62 and retaining ledges 64, 66. Securement prongs 53 on the back edge 54 of the front wand securement stop assembly 50 extend upward and during installation of the assembly 50 extend upward into receptacles formed into the base of the collection drum.

Turning now to the rear wand securement assembly 70, which is spaced apart and opposite from the front securement assembly 50, the rear assembly 70 includes a tool caddy receptacle 48 (alternatively referred to as an accessory storage bin) that is formed with and is a part of the rear wand securement assembly 70, and which aligns with an outward wall of the collection drum 22, wherein the caddy region 48 further includes a bottom wall, or floor, 74 from which a continuous side wall 72 upwardly extends. Referring to FIGS. 8-10, the rear securement assembly 70 includes a caddy region 48 having an open side toward the peripheral wall of the drum 22, and wheel axle sleeves 78 extending outwardly from the assembly 70. The remaining peripheral walls 72 of the caddy complete the enclosure of the sides of the caddy region of the rear assembly 70 when the caddy is installed around the drum. The caddy may have an additional wall enclosing the tank facing side. However, such a wall is not necessary. Like the drum 22, the rear securement assembly 70 and associated caddy region 48 may be of a one piece plastic molding. The floor 74 of the caddy region typically has a concavely curved internal periphery 76 which mates with the periphery of the drum 22 so that the caddy region 48 of the rear securement assembly 70 can be pressed against the drum 22 without leaving a space between them.

Molded under the floor 74 of the assembly 70, as well as extending from hubs 77 in the body of the assembly 70, there are caddy mounting fixtures 73 and 75 which are spaced apart from each other and correspond to the locations of the indented receiving receptacles 96 beneath the drum 22. On each fixture 73, 75 an opening extends substantially therethrough, which is placed and shaped to receive the respective securement means (such as a threaded screw) inside the respective receptacle 96 beneath the drum 22. By inserting a securement means into the opening 96, the fixture 73, 75 is installed in the receptacle 96 beneath the tank which secures the caddy to and beneath the drum.

As illustrated in FIG. 8 and FIG. 9, the rear wand securement assembly 70 further includes openings 80 extending through the walls 72, located near the intersection of the walls 72 and the floor 74, and spaced apart from each other. A section of the floor 74 of assembly 70 extends inward toward the drum 22, and is shaped to support the wands 38, the shape being similar to the exterior shape of the wands themselves. A cylinder, or retaining ring 86 extends from the exterior of the rear securement assembly 70 inward in a substantially orthogonal manner, relative to the back wall 72′ of the assembly 70 defining the caddy region 48. A plurality of wand centering ribs 82 are formed in the inside wall, preferably the upper inside wall, of retaining ring/cylinder 86 proximate the back wall of the accessory storage bin 48. These centering ribs 82 can align with grooves formed on the exterior of the wands 38 to prevent wand rotation and/or to act as further retaining means in securing the wands in position beneath the drum. Additionally, one or more springing means, such as spring fingers 84, can be located on the bottom inside wall of cylinder 86, substantially opposite wand centering ribs 82, so as to elevate the extension wands 38 into the arched channel 41, 43 formed in the bottom face of the vacuum drum 22 and guide them towards the front securement assembly 50, or both.

In typical use, when a user has completed a vacuuming operation and wants to store the hose extension wands 38, the user inserts the front end 37 through an opening 80 in the rear assembly 70. As the wand 38 is inserted, spring finger 84 elevates and directs the wand into a shaped channel 41 in the bottom face of the collection drum 22. Further insertion by the user directs the front end 37 of the wand to abut with stop 59, and simultaneous retainment in position by a pinch finger 56 entering the interior of the wand 38 as it abuts stop 59. In this manner, extension wand 38 is stored below the collection drum 22, extending only minimally, if at all, at the back end 39 of the wand from the rear face of the rear securement assembly 70.

Other and further embodiments utilizing one or more aspects of the inventions described above can be devised without departing from the spirit of Applicant's invention. For example, the shape of the debris collection drum may be round, square, rectangular, or any other appropriate shape, or the latching mechanisms for attaching the motor and lid to the collection drum may be offset, or on the same side if desired. Further, the various methods and embodiments of the use and assembly of the vacuum cleaners described herein can be included in combination with each other to produce variations of the disclosed methods and embodiments. Discussion of singular elements can include plural elements and vice-versa.

The order of steps can occur in a variety of sequences unless otherwise specifically limited. The various steps described herein can be combined with other steps, interlineated with the stated steps, and/or split into multiple steps. Similarly, elements have been described functionally and can be embodied as separate components or can be combined into components having multiple functions.

The inventions have been described in the context of preferred and other embodiments and not every embodiment of the invention has been described. Obvious modifications and alterations to the described embodiments are available to those of ordinary skill in the art. The disclosed and undisclosed embodiments are not intended to limit or restrict the scope or applicability of the invention conceived of by the Applicants, but rather, in conformity with the patent laws, Applicants intend to fully protect all such modifications and improvements that come within the scope or range of equivalent of the following claims.
