Abstract
Abstract A four-way pallet formed in one piece from structural foam plastic material and having features which accommodate rapid molding of the pallet. The pallet is formed in an injection molding process wherein the stringers separating upper and lower decks of the pallet are formed with openings therein which reduce the effective cross-sectional area of the stringers and thus speed up the curing and cooling of the pallet within a mold.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
175 words
A four-way pallet construction formed in one piece by injection molding from structural foam plastic material and comprising upper and lower decks separated by and integrally formed with at least three spaced parallel stringers providing spaces therebetween for the reception of the spaced forks of a fork lift truck, two of said stringers being at two opposite edges of the pallet and at least a third of said stringers being intermediate said two stringers, the end side walls of said pallet at the ends of said stringers having openings therein to receive said spaced forks from two opposite sides of said pallet, aligned notches formed in the bottoms of said stringers for receiving from the other two opposite sides of said pallet the spaced forks of a fork lift truck, and a pair of spaced openings formed in said lower deck, said openings extending between said other two opposite sides of the pallet but having lengths less than the width of the pallet and being positioned beneath the notches in said third of said stringers.
Claim 2
Dependent Claim
175 words
A four-way pallet construction formed in one piece by injection molding from structural foam plastic material and comprising upper and lower decks separated by and integrally formed with at least three spaced parallel stringers providing spaces therebetween for the reception of the spaced forks of a fork lift truck, two of said stringers being at two opposite edges of the pallet and at least a third of said stringers being intermediate said two stringers, the end side walls of said pallet at the ends of said stringers having openings therein to receive said spaced forks from two opposite sides of said pallet, aligned notches formed in the bottoms of said stringers for receiving from the other two opposite sides of said pallet the spaced forks of a fork lift truck, and a pair of spaced openings formed in said lower deck, said openings extending between said other two opposite sides of the pallet but having lengths less than the width of the pallet and being positioned beneath the notches in said third of said stringers.
Claim 3
Dependent Claim
20 words
