Abstract

A plastic pallet (10) includes two identical decks (12, 120) that are interconnected by identical connectors (14). Each connector includes a central core (20) and a surrounding sleeve (44) interconnected by spokes (46). The core has flexible tangs (28) that extend beyond opposite ends of the sleeve and lock onto the deck. Each deck includes a plurality of respective segments (130) consisting of a pair of open shells (132, 134) and the periphery of each deck is reinforced by respective segments (182) that are internally reinforced by gussets (192, 194).

Claims

1. A plastic pallet comprising a pair of substantially identical decks interconnected by a plurality of connectors with aperture means at at least each corner of said decks receiving said connectors, each said deck including a one-piece molded, generally rectangular structure having spaced, generally parallel surfaces surrounded by peripheral reinforcing means, said peripheral reinforcing means including a plurality of substantially identical hollow rectangular segments defined by opposed end walls and opposed side walls with a connecting wall joining one edge of each of said end and side walls, said connecting wall being inclined with respect to said deck surfaces, having a slope from one said end wall to said other end wall and having drainage means therein, and reinforcing gussets integral with said connecting wall and respective ones of said opposed side walls.

2. A plastic pallet as defined in claim 1, in which each of said decks includes a plurality of substantially identical hollow segments, each said hollow segment including a pair of hollow, rectangular shells respectively open adjacent respective parallel surfaces.

3. A plastic pallet as defined in claim 2, in which each said segment includes three substantially parallel spaced walls integral with a pair of side walls, a first pair of spaced walls and said side walls having an end wall adjacent a first of said surfaces and a second pair of spaced walls and said side walls having an end wall adjacent a second of said surfaces.

4. A load-bearing pallet as defined in claim 1, in combination with a separator tool for separating said connectors from said decks, said tool comprising a main body that is tapered from substantially a point at one end with a slot extending from said one end, said slot having a width that is greater than the diameter of said core so that said tool can be forced between said plane and an adjacent surface of said deck to apply sufficient force to flex said tangs and release said connector from said deck.

5. A plastic pallet comprising a pair of substantially identical decks interconnected by a plurality of connectors with aperture means at at least each corner of said decks receiving said connectors, each said deck including a one-piece molded, generally rectangular structure having spaced, generally parallel surfaces surrounded by peripheral reinforcing means, said peripheral reinforcing means including a plurality of substantially identical hollow rectangular segments, defined by opposed ends walls and opposed side walls with a connecting wall joining one edge of each of said end and side walls, and reinforcing gussets integral with said connecting wall and respective ones of said opposed side walls, and each said deck including a plurality of substantially identical hollow segments, each said hollow segment including a pair of hollow shells respectively open adjacent respective parallel surfaces and having three spaced walls integral with a pair of said walls, a first pair of spaced walls and said side walls having an end wall adjacent a first of said surfaces and a second pair of spaced walls and said side walls having an end wall adjacent a second of said surfaces, said aperture means including a generally U-shaped annular segment defining an abutment surrounding an opening which receives said connector and connecting means connecting said annular segment along one of said surfaces.

6. A load-bearing pallet comprising a pair of substantially identical decks having a plurality of spaced openings therein which are positioned to be vertically aligned and connector members received into said openings for interconnecting said decks, each said connector member including a substantially circular hollow central core having a plurality of flexible tangs extending from opposite ends thereof and received into said openings of respective decks to releasably interconnected said decks and an inwardly-directed force-absorbing flange intermediate opposite ends of said core.

7. A load-bearing pallet as define din claim 6, in which each said connector member includes a plurality of integral spokes extending from said central core between said flexible tangs with a sleeve integral with the free ends of said spokes, said spokes and sleeve defining planes that engage adjacent surfaces of respective frame members.

8. A load-bearing pallet as defined in claim 6, in which said core includes inner longitudinal ribs extending from said flange to a free end of each of said tangs.

9. A load-bearing pallet as defined in claim 6, in which said tangs on respective ends of said core are circumferentially offset from each other and each tang has a tapered barb on an outer surface aligned with an inner rib.

10. A load-bearing pallet as defined in claim 6, in which each of said decks includes a plurality of substantially identical hollow segments.

11. A load-bearing pallet as defined in claim 10, further comprising reinforcing means around the periphery of each deck.

12. A load-bearing pallet as defined in claim 11, in which said reinforcing means includes a plurality of substantially identical hollow shells.

13. A load-bearing pallet as defined in claim 10, in which each of said segments has spaced opposed parallel surfaces, each of said segments including a pair of open hollow shells respectively opening toward respective surfaces.

15. A load-bearing pallet as defined in claim 6, in combination with a separator tool for separating said connectors from said decks, said tool comprising a main body that is tapered from substantially a point at one end with a slot extending from said one end, said slot having a width that is greater than the diameter of said core so that said tool can be forced between said plane and an adjacent surface of said deck to apply sufficient force to flex said tangs and release said connector from said deck.

14. A load-bearing pallet comprising a pair of substantially identical decks having a plurality of spaced openings therein which are positioned to be vertically aligned and connector members received into said openings for interconnecting said decks, each said connector member including a substantially circular hollow central core having a plurality of flexible tangs extending from opposite ends thereof and received into said openings of respectively decks to releasably interconnect said deck, each said connector member further including a plurality of integral spokes extending from said central core between said flexible tangs with a sleeve integral with the free ends of said spokes, said spokes and sleeve defining planes that engage adjacent surfaces of respective decks, said sleeve including tapered portions between adjacent pairs of spokes and in which alternating tapered portions are reversely tapered.
