Abstract
The present invention is a structurally stable utility cart having a collapsible kneeling board to cushion the knees of the user and a collapsible hand support that the user can grab hold of when shifting to and from kneeling or crouching positions to upright standing positions. The kneeling board and hand support are independently collapsible without one affecting the movement of the other. Further, the device is readily collapsible for compact storage without substantially affecting the overall structural stability. The present invention also provides a utilitarian container, generally for storing various gardening tools.
Claims20
A utility cart comprising:
- a main frame comprising:
- a pair of generally parallel "J"-shaped members each including a top portion, a straight portion, and a hook portion;
- a handle fixedly joined between each top portion of said "J"-shaped members;
- an axle housing fixedly joined between each said hook portion of said "J"-shaped members;
- an axle housed in said axle housing;
- a pair of wheels attached to said axle;
- a pair of extensions each attached to, and extending linearly downward from, said straight portions of each of said "J"-shaped members whereby each associated said hook portion and said extension diverge and said extension having a ground contacting portion;
- a kneeling board having an upper surface and a lower surface and including a board hinging portion;
- a first hinge means for rotatably attaching said board hinging portion onto each said extension;
- a hand rest having an upper and lower surface including a rest hinging portion;
- a second hinge means for rotatably attaching the rest hinging portion onto the straight portions of said "J"-shaped members;
- a first counter-rotative means for preventing over rotation of said kneeling board beyond the desired amount of rotation when said board is fully folded;
- a second counter-rotative means for preventing over rotation of said hand rest, beyond the desired amount of rotation when said hand rest is fully folded or unfolded;
- securing means for securing said hand rest in a substantially horizontal position;
- a container;
- and
- attaching means for detachably attaching said container onto said main frame;
- wherein said kneeling board and said hand rest are coplanar with said pair of extensions in the folded position.

A utility cart comprising:
- a main frame structure comprising:
- a handle portion having opposite ends,
- a pair of upper extensions extending vertically downward at an acute angle, from the opposite ends of the handle portion,
- a pair of lower extensions each having a first and second end, further extending downwards from their respective upper extensions,
- a pair of curved extensions arching downwardly from their respective lower extensions to complete a structure that is a substantially "J"-shaped configuration which has been slightly pivoted,
- an axle housing that interconnects the ends of said curved extensions,
- an axle housed in said axle housing,
- a pair of wheels rotatably attached to said axle,
- a lower brace member connecting said lower extensions, and
- an upper brace member connecting said upper extensions of said main support structure;
- a main leg structure comprising:
- a rest extension having opposite ends,
- a pair of inclined portions extending in a substantially downward direction from said opposite ends of said rest extension toward a point between said upper extensions and said lower extensions,
- a pair of upper elongations extending downward from said inclined portions, adjacent said lower extensions,
- a pair of lower elongations further extending parallel to said upper elongations, and
- a pair of end caps coupled with the second end of each of said lower elongations;
- a lower rest frame having a top surface and a bottom surface;
- a foot bar, having a first end and a second end, attached to said lower rest frame adjacent said bottom surface of said lower rest frame;
- a first hinge means for rotatably attaching said lower rest frame to said lower elongations of said main support structure, enabling said lower rest frame to be folded in and out of said main leg structure, with first end and said second end of said foot bar engaging said upper elongations in the folded position to prevent further movement of said lower rest frame;
- an upper rest frame having a top surface and a bottom surface;
- a support bar having left and right lip extensions, each fixedly attached to said upper rest frame adjacent said bottom surface of said upper rest frame;
- a second hinge means for rotatably attaching said upper rest frame to said upper extensions of said main frame structure, enabling said upper rest frame to be folded in and out of said main frame structure, with said left and right lip extensions of said support bar catching said upper extensions of said main frame structure in the folded position to prevent further movement of said upper rest frame;
- upper and lower securing means, for attaching said main frame structure and said main leg structure together;
- and
- a container, having attaching means, for detachably securing said container onto said lower brace member and said upper brace member.
