Abstract
Abstract A warehouse pallet for the handling and storage of goods comprises two spaced, horizontal grids made of steel tubing and separated by a pair of spaced vertical runners and a plurality of peripheral stanchions. The runners are judiciously located to provide a convenient guide for the prongs of a fork-lift. Removable lateral extensions increase the load-carrying surface of the pallet. The pallets include sockets welded to the four corners which engage four upright posts whose upper ends are stabilized by spacing connectors and which fit into the sockets of an overlapping pallet, enabling the stacking of an indefinite number of pallets to optimize space utilization.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
297 words
A warehouse pallet comprising: first tubular steel members comprising an upper grid platform including: a tubular steel perimeter of generally rectangular cross section and including a first pair of straight sections defining sides of a rectangular outline and a second pair of straight sections defining ends of the rectangular outline, and tubular steel stringers of generally rectangular cross section extending parallel to the first pair of straight sections of the perimeter and each welded to each of the second pair of straight sections, one surface of the perimeter and one surface of each of the stringers defining an upwardly facing upper plane; a lower grid platform comprising a plurality of second tubular steel members of generally rectangular cross section and defining a downwardly facing lower plane parallel to the upper plane, at least spaced-apart areas of the second tubular members of the lower grid platform being aligned with and directly below areas of the first tubular members; and a plurality of support members located between juxtaposed surfaces of the steel members of both of the platforms to hold the platforms in rigidly spaced relation, the support members including: tubular steel spacer stanchions of generally rectangular cross section extending perpendicularly to the planes of the platforms in line between and welded to the spaced-apart areas of the second tubular steel members and the areas of the first tubular steel aligned therewith, and additional tubular steel members of rectangular cross section welded to interior regions of the upper platform and to interior regions of the lower platform directly therebelow, the additional steel members and at least predetermined ones of the stanchions defining passageways below the upper grid platform to receive the prongs of a fork-lift to engage the upper grid platform transversely to the longitudinal direction of the stringers.
Claim 2
Dependent Claim
297 words
A warehouse pallet comprising: first tubular steel members comprising an upper grid platform including: a tubular steel perimeter of generally rectangular cross section and including a first pair of straight sections defining sides of a rectangular outline and a second pair of straight sections defining ends of the rectangular outline, and tubular steel stringers of generally rectangular cross section extending parallel to the first pair of straight sections of the perimeter and each welded to each of the second pair of straight sections, one surface of the perimeter and one surface of each of the stringers defining an upwardly facing upper plane; a lower grid platform comprising a plurality of second tubular steel members of generally rectangular cross section and defining a downwardly facing lower plane parallel to the upper plane, at least spaced-apart areas of the second tubular members of the lower grid platform being aligned with and directly below areas of the first tubular members; and a plurality of support members located between juxtaposed surfaces of the steel members of both of the platforms to hold the platforms in rigidly spaced relation, the support members including: tubular steel spacer stanchions of generally rectangular cross section extending perpendicularly to the planes of the platforms in line between and welded to the spaced-apart areas of the second tubular steel members and the areas of the first tubular steel aligned therewith, and additional tubular steel members of rectangular cross section welded to interior regions of the upper platform and to interior regions of the lower platform directly therebelow, the additional steel members and at least predetermined ones of the stanchions defining passageways below the upper grid platform to receive the prongs of a fork-lift to engage the upper grid platform transversely to the longitudinal direction of the stringers.
Claim 3
Dependent Claim
21 words
The invention as defined in claim 1 in which the lower grid platform is substantially identical to the upper grid platform.
Claim 4
Dependent Claim
43 words
The invention as defined in claim 1 in which the additional tubular steel members welded to interior regions of the upper and lower platforms comprise runners extending parallel to the other pair of the sections of the perimeter of the upper grid platform.
Claim 5
Dependent Claim
34 words
The invention as defined in claim 3 in which there are two such runners spaced apart parallel to each other less than the distance between the prongs of a fork-lift to guide the prongs.
Claim 6
Dependent Claim
25 words
The invention as defined in claim 1 in which the perimeter has four curved corners joined together into the rectangular outline by the straight sections.
Claim 7
Dependent Claim
37 words
The invention as defined in claim 1 comprising an upwardly directed side member comprising a respective socket mounted at each corner to engage and support a respective one of the four upright posts of a pallet-stacking frame.
Claim 8
Dependent Claim
32 words
The invention as defined in claim 6 wherein the sockets are flared and the bottoms of said posts are tapered to facilitate mating each post to its respective socket when stacking pallets.
Claim 9
Dependent Claim
53 words
The invention as defined in claim 6 comprising a pallet-stacking frame comprising two identical pairs of upright posts, each pair of posts engageable in a pair of the sockets and having an upper connector extending from the respective post pair with means for positively embracing the upper connector of the other post pair.
Claim 10
Dependent Claim
46 words
The invention according to claim 8 wherein each of the sockets defines upwardly and downwardly directed socket elements and the stacking frame posts each defines an upright upper end to engage the downwardly directed socket of an overlying pallet for positive stacking engagement of successive pallets.
Claim 11
Dependent Claim
40 words
The invention according to claim 9 wherein each of said upper connectors comprises a generally V-shaped brace linking the respective posts and an arcuate hook extending from generally centrally of the respective brace to engage over the other the braces.
Claim 12
Dependent Claim
27 words
The invention according to claim 8 wherein the means for positively embracing each upper connector comprises a pin engageable in a socket defined in the embraced connector.
Claim 13
Dependent Claim
34 words
The invention according to claim 1 including a pallet extension having means to engage the upper and lower platforms to define, when engaged, a projected continuation of the upper surface of the upper platform.
Claim 14
Dependent Claim
47 words
The invention according to claim 12 wherein the upper and lower platforms each have a continuous peripheral header beam and said means to engage comprise a pair of beams to lie substantially flush against the header beams and a plurality of hooks to hook over the latter.
