DESCRIPTION:
BRIEF SUMMARY
This invention concerns a pallet, and more particularly a pallet of the kind comprising a pallet base providing a supporting surface with an entry space therebelow to receive the fork of a fork lift truck, and side members that are attachable to the base to enclose goods supported thereon and to allow loaded pallets to be stacked one above the other.
It is an object of the invention to provide a pallet system comprising base and sides that are of modular construction enabling simplified assembly of the pallet from few standard parts.
Further preferred objects of the invention, not necessarily in order of importance, are as follows: required. assembled and loaded, either singly or when coupled in pairs. with more than two pallet bases linked together. both sides and ends, of a single or double pallet base. namely the pallet base and a standard side member.
According to one aspect of the invention, a pallet system comprises a pallet base providing a horizontal supporting surface of generally rectangular, preferably square, outline and having an array of vertically aligned connecting means at each corner, and a plurality of side members each including a pair of uprights arranged to mate with corresponding connecting means of said arrays at two corners of the base, one upright of each pair including locating means for embracing the other upright of another side member in order to maintain relative alignment of the uprights in a horizontal direction.
According to another aspect of the invention, there is provided a pallet system including a modular base element providing a horizontal supporting surface and arranged to mate with a similar element at one horizontal edge, by interengagement along a horizontal axis, and a modular side element arranged to mate with the base element in order to stand vertically at a horizontal edge thereof, the side element being capable of being assembled with the base in either of two relatively horizontally displaced positions in one of which a vertical edge thereof can engage and locate a corresponding vertical edge of a similar element assembled to an adjacent horizontal edge of the same base element, to form a corner, and in the other of which a vertical edge thereof can engage and locate a corresponding vertical edge of a similar element assembled to an adjacent horizontal edge of another base element mating with the first, to form an extended coplanar vertical wall.
Further preferred features of the invention relevant to the preferred objects will become apparent from the following description and the drawings, in which:
FIG. 1 is a plan view of the base of a pallet in accordance with the invention, shown with the top surface removed to expose the frame work,
FIG. 2 is a side elevation of the pallet of FIG. 1, taken from the bottom of the drawing as viewed in FIG. 1, shown with lower supporting cross members omitted for clarity,
FIG. 3 is a sectional elevation on the line III--III of FIG. 1 showing the lower cross members omitted from FIG. 2,
FIG. 4 is a side elevation of the pallet base of FIG. 1 viewed from the right hand side of the drawing as shown in FIG. 1,
FIG. 5 is a side elevation of a side member for use with the base of FIG. 1,
FIG. 5A is a fragmentary plan view of the side member of FIG. 4,
FIG. 6 is a diagram illustrating the assembly of base and side units to form a single enclosed pallet, and
FIG. 7 is a diagram illustrating the assembly of bases and side members as shown in FIGS. 1 to 5, to form an enclosed double pallet.
Referring to FIGS. 1 to 4 of the drawings, a pallet base comprises a generally square frame formed by side members 1 to 4 of steel section, typically tube, the ends of which are welded to corner angle pieces 5 each of which comprises three sections 6, 7, and 8 of steel tube of square cross-section, welded together and extending vertically.
Two opposite side members 1 and 4 are interconnected by cross-members 9 and 10 also of steel section, and two further cross-members 11 and 12 of steel section are in turn welded below the side members 2 and
