Abstract

A platform structure of the pallet type having on one side thereof a load bearing sheet structure and on the opposite side leg formations defining entry ways for a lifting fork prong and wherein the leg formation is made of at least partly corrugated sheet material. The leg formation comprises a pair of spaced apart coplanar flat strip portions attached to the sheet structure and between the flat strip portions and integral therewith two contiguous V-profiles extending lengthwise and parallel to each other. The two profiles define a valley of triangular shape into which a triangular reinforcement is inserted.

Claims

1. A platform structure of the pallet type having a lengthwise and a widthwise extension and on one side thereof a load bearing sheet structure with a load bearing face and a back face and on the opposite side thereof at least two leg formations defining therebetween entry ways for a lifting fork prong and wherein each leg formation is made of at least partly corrugated sheet material, wherein, according to the improvement, each said leg formation comprises a pair of spaced apart coplanar flat strip portions attached to said back face of said sheet structure, and between said flat strip portions and integral therewith two contiguous V-profiles extending lengthwise and parallel to each other, each V-profile having a free vertex edge at a distance from said back face, said two profiles defining a valley of triangular shape therebetween and opening away from said back face, the aperture of said valley being defined by the distance between the free vertex edges of said contiguous V-profiles and within said valley a triangular reinforcement inserted therein, said triangular reinforcement having its base side closing said aperture and cooperating with said free edges of said V-profile to define together therewith an increased resting surface for said platform structure, and to prevent deformation of said V-profile.

2. A structure according to claim 1, wherein more than one of said leg formations are arranged in aligned relationship to each other and at a distance from each other allowing insertion therebetween of a lifting fork prong.

3. A structure according to claim 1, wherein more than one of said leg formations are arranged in side by side relationship at a distance from each other and with a length of the V-profiles shorter than the lengthwise extension of said platform thereby to define with said strip portions and said V-profiles integral to each other a band of spaced apart leg formations extending widthwise to said platform, the distance between the successive leg formations allowing insertion therebetween of a lifting fork prong.

4. A structure according to claim 3, wherein more than one of said bands are arranged at a distance from and parallel to each other widthwise to said platform and with said leg formations in alignment relationship with each other and wherein said distance between said bands and said distance between said leg formations allowing insertion therebetween of a lifting fork prong, thereby allowing insertion of a prong from four sides of the platform.
