Abstract

Abstract A rigid foamed plastic pallet comprises a deck and a series of runners which are integral with and depend from the lower surface of the deck. The pallet is strengthened by reinforcing members which are located in the deck and in the runners of the pallet. The pallet is formed by constructing a frame of reinforcing members, placing the assembled frame in a mold, depositing foamed plastic in the mold and allowing the foamed plastic to harden.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 213 words
A rigid foamed plastic pallet comprising: a. a deck, said deck having an upper surface and a lower surface, and said deck having end walls and side walls extending between said upper and lower surfaces, b. runners integral with said deck, said runners projecting downward from the lower surface of said deck and extending generally parallel with respect to said side walls of saId deck, and c. elongate reinforcing members comprising wood and extending along said end walls and being embedded in said deck, with each of said reinforcing members reinforcing at least part of a lower edge of one of said end walls and having a first longitudinal surface adjacent and parallel to the lower surface of said deck and a second longitudinal surface adjacent and parallel to one of the end walls of said deck; d. at least some of said runners having pairs of recesses in their undersides for receiving forks of a forklift truck; and e. at least some of said runners also being provided with elongated reinforcing members, comprising wood, said reinforcing members being embedded in an underside of said runners, said reinforcing members extending longitudinally with respect to said runners, and said reinforcing members each having a longitudinal surface at said underside of one of said runners.
Claim 2
Dependent Claim 213 words
A rigid foamed plastic pallet comprising: a. a deck, said deck having an upper surface and a lower surface, and said deck having end walls and side walls extending between said upper and lower surfaces, b. runners integral with said deck, said runners projecting downward from the lower surface of said deck and extending generally parallel with respect to said side walls of saId deck, and c. elongate reinforcing members comprising wood and extending along said end walls and being embedded in said deck, with each of said reinforcing members reinforcing at least part of a lower edge of one of said end walls and having a first longitudinal surface adjacent and parallel to the lower surface of said deck and a second longitudinal surface adjacent and parallel to one of the end walls of said deck; d. at least some of said runners having pairs of recesses in their undersides for receiving forks of a forklift truck; and e. at least some of said runners also being provided with elongated reinforcing members, comprising wood, said reinforcing members being embedded in an underside of said runners, said reinforcing members extending longitudinally with respect to said runners, and said reinforcing members each having a longitudinal surface at said underside of one of said runners.
Claim 3
Dependent Claim 49 words
