Abstract
Abstract A plastic pallet having a plurality of downwardly extending hollow conical struts, each of which is provided with an asymmetrical concavity, with all concavities facing the same direction, the struts being receivable within corresponding struts of an adjacent pallet whereby, in a first orientation the space between adjacent pallets is decreased for storage purposes, and in a second orientation the space between the stacked pallets is increased for receiving a fork-lift therebetween.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
184 words
A pallet of the type including a support platform and a plurality of hollow, conical-shaped struts extending downwardly from the platform for nesting engagement within corresponding struts of an adjacent pallet to permit stacking of the pallets, the improvement comprising: a) each conical strut including a lower portion provided with an asymmetrical concavity which extends inwardly from one side of the lower portion approximately one-half of the width thereof, each concavity being partially defined by an inner horizontal wall and an outer horizontal wall, and all concavities facing in the same direction to permit nesting of two adjacent pallets in either of first and second nesting orientations; wherein b) in the first nesting orientation, the inner and outer horizontal walls of the adjacent pallets are disposed in corresponding respective engagement with each other for decreasing the spacing between the support platforms of the nested pallets; and c) in the second nesting orientation, the outer horizontal walls of one pallet are disposed in engagement with the inner horizontal walls of the other pallet for increasing the spacing between the support platforms of the nested pallets.
