Abstract
A pallet having a substantially inelastic flexible load-supporting platform and a plurality of support blocks for maintaining the platform above a ground support. To transport the pallet and its load from place to place, a lifting assembly has a pair of forks for fitting in channels between the support blocks. The forks are laterally extendable with respect to each other, so that a side of each fork can engage a facing side of a support block to maintain the support block and a load thereon in a substantially upright position.
Claims2
A foldable and reusable soft pallet intended for supporting a load and moving the load by means of a lifting mechanism having a pair of laterally-separated forks, each fork having a top member and a side member extending downwardly from the top member, and the lateral separation between the forks being selectably variable between a proximal separation and a distal separation, the pallet comprising:
- a flexible platform formed of flexible textile material and having an upper surface operative to receive the load;
- first and second support blocks affixed in laterally spaced apart relation on a lower surface of the flexible platform to support the flexible platform and a load received thereon in elevated relation to a ground surface when the support blocks rest on the ground surface;
- at least one other support block affixed on the lower surface of the flexible platform, the other support block extending between and parallel to the first and second support blocks so as to further support the flexible platform and the load in elevated relation to the ground surface, with the other support block laterally spaced apart from the first and second support blocks to define elongated regions for receiving the forks in proximal separation beneath the lower surface of the flexible platform without interference with the support blocks;
- the first and second support blocks each having a side face depending from the lower surface of the flexible platform and facing the respective fork-receiving regions so that distal separation of the forks in said regions engages the side faces by the confronting side members of the forks and urges apart the first and second support blocks, thereby applying lateral tension to the flexible platform sufficient to support the load thereon when the forks lift the pallet above the ground surface and applying a force moment to the first and second support blocks sufficient to maintain said support blocks substantially level when the pallet is lifted;
- the flexible platform having tensile strength sufficient to withstand the lateral tension applied thereto by the first and second support blocks while supporting a predetermined load;
- the flexible platform being sufficiently flexible to permit nondestructive folding intermediate the support blocks without weakening the flexible platform for subsequent unfolding and reuse, so that the support blocks rest approximately one alongside the other, thereby substantially reducing the overall size of the folded pallet for shipping or storing;
- and
- the textile material of the flexible platform having sufficient tensile strength to withstand said lateral tension.
