WIRE-FORMED PALLET
Abstract
A heavy duty wire-formed pallet is provided which is light in
weight, but yet which is rugged in its construction. The pallet of
the invention may be stacked with other like pallets to be stored
in a minimum of space when not in use. The pallet is constructed to
be capable of supporting heavy loads without sagging or damage. The
structure incorporates a pair of side rails formed of metal strips,
and which are supported at the ends of appropriate pedestals, to
constitute a stable, wide-tread supporting base for the pallet when
it is heavily loaded.

Claims
What is claimed is:
1. A load-bearing wire-formed pallet comprising: a peripheral strip
member configured to circumscribe a predetermined rectangular area
and to define end edges and side edges for the pallet; a first
plurality of U-shaped wire rods affixed to said peripheral strip
member and extending in spaced parallel relationship across the
rectangular area from one of the side edges to the other; a second
plurality of U-shaped wire rods affixed to said peripheral strip
member and extending in spaced parallel relationship transversely
across the rectangular area from one of the end edges to the other
in transverse relationship with the rods of the first plurality; a
plurality of pedestals for the pallet mounted at each side thereof,
each of said pedestals being formed of a flat metallic strip
configured to a generally U-shaped configuration having downwardly
converging sides; a pair of flat strips affixed to the pedestals
and extending along each side of the pallet in spaced parallel
relationship with the plane of said rectangular area to constitute
support rails for the pallet; and a plurality of additional wire
rods extending across the rectangular area from one of the side
edges to the other in space and parallel relationship with certain
of the wire rods of the second plurality on opposite sides of the
wire rods of the first plurality with respect thereto to form
trusses, said pedestals being affixed to respective ones of the
additional rods.
2. The load-bearing wire-formed pallet defined in claim 1 in which
said wire rods of said first and second pluralities have a
rectangular section of the height of each of said rods being
greater than the width.
3. The load-bearing wire-formed pallet defined in claim 1 in which
said wire rods of the second plurality are affixed to the wire rods
of the first plurality at the cross-over points thereof.
4. The load-bearing wire-formed pallet defined in claim 1 in which
said strip forming said support rails have openings therein of a
particular configuration and extending along the length thereof.
Description
BACKGROUND OF THE INVENTION
Most prior art pallets are made of wood, and although usually cheap
and inexpensive, they may be easily broken. The prior art wooden
pallets are difficult to clean, and they are relatively heavy. The
wire formed pallet of the present invention, on the other hand, is
light in weight. Moreover, the pallet to be described is of a
sturdy construction, and it is not subject to breakage. The pallet
of the invention is capable of supporting heavy loads without
sagging, and in a stable manner. The pallet is easy to clean, for
example, by a detergent spray.
The pallet of the invention is constructed of metal wire rods and
metallic strips. The wire rods form the load bearing surface for
the pallet, which is displaced up from the supporting floor by
appropriate pedestals. As mentioned above, a pair of strips is
affixed to the lower ends of the pedestals, and extend from one end
of the pallet to the other to form a wide-tread stable load
supporting frame for the pallet.
The pedestals, as will be described, are affixed to the load
bearing surface of the pallet by additional steel rods which extend
across the pallet and form trusses with the other wire rods, so
that the pallet is capable of supporting heavy loads without
sagging.
The resulting pallet frame and the trusses at the load bearing
surface of the pallet, as mentioned, form a sturdy and strong
support for the load. The pallet is constructed so that the force
of a lift truck or pallet truck may extend freely into the sides or
ends of the pallet.
The pallet of the invention is particularly useful in warehouses
for storing or handling goods. In that respect, the particular
pallet of the invention is constructed to handle relatively heavy
loads without any tendancy for the structure to break or sag.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective representation of a wire formed pallet
constructed in accordance with the invention;
FIG. 2 is a detail showing of one corner of the pallet of FIG. 1,
and particularly illustrating the manner in which the pedestal at
that corner is attached to the load bearing surface of the pallet;
and
FIG. 3 shows the manner in which two pallets, such as the pallet
shown in FIG. 1, may be stacked on one another for storage in a
minimum space, when the pallets are not in use.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The pallet illustrated in the drawing includes a peripheral
metallic strip member 10 which is configured to circumscribe a
predetermined rectangular area, and which defines side edges and
end edges for the pallet.
A first plurality of U-shaped wire rods 12 extend from one end of
the pallet to the other in spaced parallel relationship, and these
wire rods are welded, or otherwise attached to the peripheral strip
10 at the end edges of the pallet.
A second plurality of U-shaped wire rods 14 extend transversely
across the rectangular area from one side of the pallet to the
other, and these latter wire rods are welded, or otherwise affixed
to the strip 10 at the side edges of the pallet.
The wire rods 12 are welded to the wire rods 14 at the cross-over
points. As illustrated, the wire rods preferably have a rectangular
cross section, and have a height greater than the width thereof for
maximum load support capabilities.
A plurality of pedestals 18 are mounted at each side of the pallet,
with a pedestal being positioned at each corner, and at the
intermediate point of each side. Each of the pedestals 18 is
formed, for example of a metal strip having a generally U-shaped
configuration, and each having sides converging downwardly toward
the bit portion. The pedestals are welded, or otherwise attached to
additional transverse wire rods 20 which extend transversely across
the pallet in spaced parallel relationship with corresponding rods
14, but on the opposite side of the rods 12 with respect thereto.
The additional rods 20 are also welded, or otherwise affixed to the
rods 12 at the cross-over points. The rods 20 form trusses with the
corresponding rods 14 to increase the load bearing capabilities of
the structure.
A pair of relatively wide strips 30 is welded, or otherwise affixed
to the lower ends of the respective pedestals 18, as shown. The
strips 30 extend along the side of the pallet in spaced parallel
relationship with the load bearing surface formed by the rods 12,
14 and 20. The strips 30 form stable support rails for the pallet.
Apertures may be provided in the individual strips, as shown, as
well as in the pedestals 18, to lighten the weight of the
pallet.
The pallet of FIG. 1 is designated generally as 50 in FIG. 3 and,
as shown, it may be stacked on a similar pallet 50A, so that the
pallet may be stored in a minimum space, when not in use.
The invention provides, therefore, an improved heavy duty wire
formed pallet which is capable of supporting heavy loads in a
stable manner. While a particular embodiment has been shown and
described, modifications may be made. It is intended to cover the
modifications in the following claims.
