Plastic pallet
First Claim
1. A plastic pallet comprising:
- a generally planar platform structure comprising an upper plastic sheet, defining a platform surface for the pallet, and a lower plastic sheet positioned in spaced relation beneath the upper sheet, selectively fused to the upper sheet, and defining a plurality of spaced downwardly opening pockets with each pocket including a base surface portion and sidewall surface portions in surrounding relation to the base surface portion; and
a plurality of plastic legs positioned beneath the platform structure in respective proximity to the pockets, each leg having a hollow closed box configuration and including an upper wall structure having a base surface portion having a size and shape corresponding to the size and shape of the base surface portion of a respective pocket and sidewall surface portions having a size and shape corresponding to the size and shape of the sidewall surface portions of the respective pocket, each upper wall structure being seated in a respective pocket and being fused to the plastic material of the lower sheet defining that pocket at the interfaces of the base surface portions and the sidewall surface portions, the base and sidewall surface portions of the respective pockets coacting with the base and sidewall surface portions of the respective leg upper wall structures to rigidly secure the legs to the underface of the platform structure to preclude sliding displacement of the legs relative to the platform structure in response to shearing stress forces.

Abstract
A plastic pallet comprising a generally planar platform structure defining an upper face, providing an article support surface, and an underface; a generally planar base structure defining a lower pallet support face and an upper face; and a plurality of hollow legs of closed box configuration positioned between the platform and base structures and each including an upper wall structure fused to the underface of the platform structure and a lower wall structure fused to the upper face of the base structure. The platform structure and base structure are each of twin sheet configuration and each includes an upper sheet and a lower sheet selectively fused together to form the respective structure. Pockets are provided in the lower sheet of the platform structure to receive the upper ends of the box legs and pockets are provided in the upper sheet of the base structure to receive the lower ends of the box legs. Each leg is formed from first and second thermoformed plastic parts fused together along a generally vertical seam line. The upper end of each leg is recessed in an inboard direction to allow access to a downwardly opening groove defined around the perimeter of the platform structure by a downwardly extending peripheral lip.

7. A plastic pallet comprising:
-
a planar platform structure; and a plurality of downwardly extending legs of closed box configuration spaced about the periphery of the platform structure and each including an outboard wall structure having a lower portion and an upper portion recessed inboard with respect to the lower portion; the platform structure defining a perimeter and a peripheral downwardly extending lip defining a downwardly opening groove extending around the perimeter of the platform structure; the upper portion of the wall structure of each leg being spaced inboard from the lip so as not to encroach upon the groove; and the groove being defined at least in part between the lip and the upper portion of the wall structure. - View Dependent Claims (8, 9)

10. A plastic pallet comprising:
-
a planar platform structure; and a plurality of downwardly extending legs of closed box configuration spaced about the periphery of the platform structure and each including an outboard wall structure having a lower portion and an upper portion recessed inboard with respect to the lower portion; the platform structure defining an outer perimeter and the lower portion of the wall structure of each leg being positioned approximately flush with the outer perimeter of the platform structure.
