Suitable fasteners or pins 44 laterally extend through openings in the upper flanges 42 and the tubes to secure the tubes to the upper flanges 42 and the tray 12. The illustrated upper flanges 42 are molded in the back wall 22 of the tray 12 but can alternatively be formed separately and attached thereto. It is noted that the connecting portion 40 of the handle 16 can alternatively be secured to the tray 12 in other suitable manners apparent to those skilled in the art.
The illustrated grasping portion 38 is a generally U-shaped tube wherein the ends extend from the upper ends of the connecting portion tubes. The illustrated grasping portion 38 of the handle 16 extends at angle relative to the back wall 22 such that it angles rearwardly when the bottom wall 20 is resting the ground (FIGS. 1 and 2) and is generally horizontal when the stand 18 is resting on the ground (FIG. 3). Preferably, the grasping portion 38 is shaped and sized with a transverse width suitable to fit between the side walls of another yard cart when yard carts 10 are stacked one on top of another as described in more detail hereinafter. The grasping portion 38 is also preferably sized and shaped such that the wheels 14 of another yard cart at least partially extend within the grasping portion 38 of the handle 16 when yard carts 10 are stacked one on top of another as described in more detail herein after. In this regard, the illustrated grasping portion 38 has side members which outwardly extend in a lateral direction from the tubes of the connecting portion 40 to a base member which extends a transverse distance greater than the transverse spacing of the tubes of the connecting portion 40.
The connecting and grasping portions 38, 40 of the illustrated handle are formed by a singled rigid tube bent into the desired shape. The tube can be formed of metal, plastic, or other suitable material. It is noted that the handle 16 can have other desired shapes such as, for example, straight or ergonomic shapes. The handle 16 may also include a grip (not shown) for forming a slip-resistant surface to more easily grasping the handle 16. The grip can be formed by a plurality of spaced apart protrusions and/or recesses molded or formed therein and/or can formed by an additional material such as, for example, rubber or other suitable materials.
The stand 18 is adapted to support the tray 12 in at least one orientation other than the generally vertical orientation wherein the bottom wall 20 is resting on the ground. As best shown in FIG. 3, the illustrated stand 18 is adapted to support the tray 12 in a generally horizontal orientation wherein the periphery of the cavity is generally horizontal. When in the position shown in FIG. 3, the tray 12 opens substantially upward, permitting use of the yard cart 10 as a Wheel barrow or a cart. Of course, the yard cart 10 can easily transition between positions The illustrated stand 18 is a retractable stand 18 in that it is movable between a stowed or “up” position (FIG. 1) and at least one extended or “down” position (FIG. 2). The stand 18 may be moved between the positions in any manner known in the art, including manually moving the stand 18. The illustrated stand 18 is in the form of a U-shaped bent tube wherein the free ends of the tube are pivotably connected to the back wall 22 of the tray 12. The tube can be metal, plastic, or any other suitable material. It is noted that the stand 18 can alternatively have other forms and shapes within the scope of the present invention. The illustrated stand 18 is pivotably connected by the transversely extending pins 44 connecting the handle 16 and extending through openings in the stand 18. The illustrated stand 18 extends between the upper flanges 42 along with the handle 16 and inward of the handle 16. Mounted in this manner, the stand 18 is pivotable about a transversely extending pivot axis 46 formed by the pins 44.
The stand 18 preferably includes a releasable lock device or retainer 48 which restricts movement of the kick stand, at least resisting movement of the stand out of the stowed position. In the illustrated embodiment, resilient members or fingers releasably hold the stand 18 in the stowed position. The resilient fingers are adapted to partially block path of the stand 18 to resist movement of the stand 18 out of the stowed position. When a suitable force is applied to the stand 18 to pivot the stand out of the stowed position, the fingers resiliently deform out of the path of the stand 18 to permit the kick stand to move out of the stowed position. When the stand 18 is moved back to the stowed position with a suitable force, the fingers resiliently deform out of the path to permit the stand 18 to be stowed and resiliently snap back into the path to again resist movement of the stand 18 out of the stowed position. The illustrated fingers are molded in the back wall 22 of the try 12 but can alternatively be formed separately and attached thereto. It is noted that the releasable retainer 48 can take other forms to restrict the free movement of the stand 18 such as, for example, it can restrict movement out of the stored position and the extended position and/or restrict movement from other positions.
As best shown in FIGS. 4 and 5, a plurality of the yard carts 10 can be stacked one upon another in a stacked configuration. The yard carts 10 are stacked in an alternating opposed fashion such that the yard carts 10 nest together in a compact manner resulting in a reduction in the amount of space required to store the plurality of yard carts 10. As described hereinabove, the trays 12 are preferably sized to accommodate the wheels 14 and the handles 16 from other yard carts 10 so that several yard carts 110 may be stored in a nested manner. For ease of explanation, six of the yard carts 10 are shown in the figures and it should be recognized that these yard carts 10a to 10f may be substantially identical to each other and that a greater or fewer number of the yard carts 10a to 10f may be stacked.
