Abstract

Abstract A pallet for supporting materials comprising a pair of end sections of similar construction formed of a vertically disposed end plate, a pair of flanges extending inwardly substantially perpendicularly from the upper end portion of the end plate in vertically spaced apart parallel relation and a slideway in the form of a tubular section on the lower end portion of each of the end plates, a panel dimensioned for its ends to be received between the respective flanged pairs of the end plates and a base plate extending across the pallet with the ends of the base plate received in engagement within the slideways and means for securing the elements in their assembled relationship to form the pallet.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 300 words
A pallet comprising a pair of end sections of similar construction comprising a vertically disposed end plate, a pair of flanges extending inwardly substantially perpendicularly from the upper end portion of the end plate in vertically spaced apart substantially parallel relation and a slideway in the form of a tubular section on the lower end portion of the end plate, a panel portion dimensioned to have a height corresponding to the spaced relationship between the flanges of each pair with the ends of the panels received between the flanges of each end section on opposite ends of the panel, a base plate extending between the lower end of the end plates with an enlarged portion on the ends of the base plate in engagement with the slide-ways, aligned openings through the end plates in the area between the flanges, a tie rod dimensioned to span the end plates with end portions projecting through the openings, abutments on the through-extending portions of the tie rods and means for effecting movement of the abutments in the direction toward and away from each other to increase or decrease respectively the pressure on the end plates, and in which the edge of the panel between the flanges of an end plate outermost of the panel is tapered inwardly from a point below the opening to the upper edge to provide a pivot point about which the end plate rocks in response to increased compression by the tie rod onto the end plates to place the panel under compression and the base plate in tension and which includes an intermediate plate between the end plates with the upper face of the intermediate plate in engagement with the underside of the panel and having a pedestal on the lower end which rests on the base plate.
Claim 2
Dependent Claim 300 words
A pallet comprising a pair of end sections of similar construction comprising a vertically disposed end plate, a pair of flanges extending inwardly substantially perpendicularly from the upper end portion of the end plate in vertically spaced apart substantially parallel relation and a slideway in the form of a tubular section on the lower end portion of the end plate, a panel portion dimensioned to have a height corresponding to the spaced relationship between the flanges of each pair with the ends of the panels received between the flanges of each end section on opposite ends of the panel, a base plate extending between the lower end of the end plates with an enlarged portion on the ends of the base plate in engagement with the slide-ways, aligned openings through the end plates in the area between the flanges, a tie rod dimensioned to span the end plates with end portions projecting through the openings, abutments on the through-extending portions of the tie rods and means for effecting movement of the abutments in the direction toward and away from each other to increase or decrease respectively the pressure on the end plates, and in which the edge of the panel between the flanges of an end plate outermost of the panel is tapered inwardly from a point below the opening to the upper edge to provide a pivot point about which the end plate rocks in response to increased compression by the tie rod onto the end plates to place the panel under compression and the base plate in tension and which includes an intermediate plate between the end plates with the upper face of the intermediate plate in engagement with the underside of the panel and having a pedestal on the lower end which rests on the base plate.
Claim 3
Dependent Claim 94 words
A Pallet as claimed in claim 1 in which the intermediate plate comprises a single plate having a pedestal at its lower end which rests on the base plate and having a pair of vertically spaces flanges extending perpendicularly in one direction from the upper end portion and another pair of spaced flanges extending perpendicularly in the opposite direction from the upper end portion of the intermediate plate and in which the panel section is subdivided into two panels with the adjacent inner ends engaged between the adjacent flanged sections in the intermediate plate.
Claim 4
Dependent Claim 44 words
A pallet as claimed in claim 1 in which the panels are in the form of trapezoidal members having their base portion of larger dimension lowermost whereby the lower edge of the ends of the panel engage the end plates to define pivotal points.
Claim 5
Dependent Claim 22 words
A pallet as claimed in claim 1 in which the lower surface of the upper flanges taper toward the outer free end.
Claim 6
Dependent Claim 52 words
A pallet as claimed in claim 1 in which the tubular sections on the lower ends of each of the end plates are rectangular in cross-section and in which the enlarged portions on the ends of the base plate are of similar shape for engagement within the tubular sections in telescoping arrangement.
Claim 7
Dependent Claim 34 words
A pallet as claimed in claim 1 in which the enlarged end portions on the base plate are integral with the base plate and formed by folding the edge portions of the base plate.
Claim 8
Dependent Claim 37 words
A pallet assembly which includes two pallets, as claimed in claim 1, arranged in end to end relationship to double the surface area of the pallet, and means interconnecting the adjacent end sections into a composite assembly.
Claim 9
Dependent Claim 42 words
A pallet as claimed in claim 1 in which the end plates include passages extending therethrough in the area immediately below the lower flange for passage of the forks of a lift truck into position to engage the underside of the panel.
Claim 10
Dependent Claim 63 words
A pallet as claimed in claim 1 in which the means for securing the elements in their assembled relation comprises aligned openings through the end plates in the area between the flanges, a tie rod dimensioned to span the end plates with threaded end portions projecting through the openings, and nut members threadably engaging the through-extending threaded end portions of the tie rods.
Claim 11
Dependent Claim 26 words
A pallet as claimed in claim 9 in which the aligned openings are spaced a shorter distance from the upper flange than from the lower flange.
Claim 12
Dependent Claim 25 words
A pallet as claimed in claim 1 in which the end plates are tightened onto the panel to stress the panel into a prestressed arch.
Claim 13
Dependent Claim 28 words
A pallet as claimed in claim 1 which includes brackets extending outwardly from the upper end of the end plates for receiving sling means for lifting the pallet.
