Abstract

A wheeled hand cart for use with a wet/dry utility vacuum cleaner drum is disclosed. A pair of wheel frames are mounted to the drum in spaced relationship to each other along a lower outer periphery of the drum. Each wheel frame has a horizontally extending passageway and a vertically extending channel that intersects and extends across each horizontally extending passageway. An upright handle section is positioned within the vertically extending channel of each wheel frame and has a transverse opening which is in alignment with the horizontally extending passageway of each wheel frame. Horizontally extending passageways of the spaced wheel frames are in alignment with one another to receive a wheel axle extending therethrough and also through the transverse openings of the upright handle sections. The wheels are mounted on the wheel axle for wheeled movement of the hand cart. A handle interconnects the upright handle sections to facilitate movement of the drum by the wheeled hand cart. The interconnecting handle and upright handle sections are also associated relative to the drum and an overlying drum cover in order to provide a stable and secure mounting of the wheeled hand cart relative to the drum.

Claims

1. A wheeled hand cart for use with an appliance such as a drum or the like, comprising:

a pair of wheel frames mounted to said drum in spaced relationship to each other along a lower outer periphery of the drum, each wheel frame having a horizontally extending passageway which is in corresponding aligned relationship the other, said wheel frames further each having a vertically extending channel that intersects and extends across the respective associated horizontally extending passageway in each wheel frame;

an upright handle section positioned within the vertically extending channel of each wheel frame and having a transverse opening therein for alignment with the horizontally extending passageway of each wheel frame;

a wheel axle extending through the horizontally extending passageways of both wheel frames including through the transverse openings in said upright handle sections;

wheels ;

mounted on opposite ends of said wheel axle for wheeled movement of said hand cart; and

a handle interconnecting said upright handle sections to facilitate movement of said drum by said wheeled hand cart.

2. The hand cart as defined in claim 1 wherein each wheel frame includes an upwardly extending male post for complementary association relative to a corresponding bottom opening in said drum for mounting said wheel frames to said drum.

3. The hand cart as defined in claim 2 wherein the horizontally extending passageway and intersecting vertically extending channel are provided adjacent one end of each wheel frame, and said upwardly extending male post is provided at the other end of said wheel frame.

4. The hand cart as defined in claim 3 wherein each wheel frame includes a first radially inwardly extending portion, when attached to said drum, including said upwardly extending male post, and an integral second portion angularly offset relative to said first portion and in mirror image relationship with the second portion of said other wheel frame for corresponding aligned relationship of the horizontally extending passageways of said pair of wheel frames.

5. The hand cart as defined in claim 4 wherein each wheel frame includes a hollow interior with intersecting integral fins for structural rigidity.

6. The hand cart as defined in claim 5 wherein each upwardly extending male post contains peripherally spaced upstanding ribs for deformable and interfering engagement with the corresponding associated bottom opening in said drum.

7. The hand cart as defined in claim 1 wherein said upright handle sections include a generally vertically directed flange that is positioned to fit between the drum and a depending overhanging lip of an associated drum and drum cover at an upper end of the drum.

8. The hand cart as defined in claim 7 and further including a handle bracket complementary shaped relative to said drum and extending between said upright handle sections, said complementary shaped bracket receiving and mounting said upright handle sections with respect to each other and said interconnecting handle.

9. The hand cart as defined in claim 8 wherein said complementary shaped bracket is generally horizontally aligned and configured relative to the generally vertically directed flanges of said upright handle sections in order to trap the depending overhanging lip of said drum and drum cover therebetween.

10. The hand cart as defined in claim 9 wherein said interconnecting handle and said upright handle sections comprise interfitting tubular sections for telescopic association relative to one another, said handle bracket having corresponding openings for receiving one of said interconnecting handle, or upright handle tubular sections of said upright handle sections and interconnecting handle.

11. The hand cart as defined in claim 10 wherein said interconnecting handle comprises a one-piece tubular unit which extends both upwardly from said upright handle sections and outwardly away from said drum.

12. The hand cart as defined in claim 11 and further including a pair of caster wheels mounted to said drum in spaced relationship to one another about the periphery of said drum and on an opposite side of said drum from said wheeled hand cart.

13. The hand cart as defined in claim 12 and further including integral outwardly facing hook portions for engaging and mounting a removable container relative to said drum.

14. In a wet/dry utility vacuum cleaner having a hollow drum for collecting debris, the improvement comprising a wheeled hand cart mounted to said hollow drum for moving and re-positioning same, said wheeled hand cart including:

a pair of spaced wheel frames mounted to said drum about a lower outer periphery thereof, said wheel frames further each having a horizontally extending passageway and a vertically extending channel that intersects and extends across each horizontally extending passageway, said wheel frames being mounted to said drum to permit the horizontally extending passageways of each wheel frame to be in alignment with one another;

an upright handle section positioned within the vertically extending channel of each wheel frame and having a transverse opening therein for alignment with the horizontally extending passageway of each wheel frame, said upright handle sections being interconnected to one another;

a wheel axle extending through the horizontally extending passageways of both caster wheel frames including through the transverse openings in said upright handle sections; and

wheels mounted on opposite ends of said wheel axle for wheeled movement of said hand cart.

15. The improvement as defined in claim 14 and further including a handle bracket complementary shaped relative to said drum which extends between said upright handle sections, and an interconnecting handle extending through openings provided in said handle bracket and being telescopically associated relative to upright handle sections.

16. The improvement as defined in claim 15 wherein said upright handle sections each have a generally vertically extending flange which is generally horizontally aligned relative to complementary shaped handle bracket and suitably dimensioned to engage the drum adjacent an overhanging depending lip of a drum and associated drum cover which overlies an upper end of said drum, while the overhanging depending lip of the drum cover is trapped between each generally vertically extending flange and handle bracket.

17. The improvement as defined in claim 16 wherein said wheel frames, when attached to said drum, include a first radially inwardly extending portion containing said wheel and a second portion angularly offset from said first portion and generally in mirror image relationship with the second portion of said other wheel frame, said second portion of said wheel frames containing said horizontal extending passageway and intersecting vertically extending channel.
