WIRE-FORMED PALLET
Abstract
An improved wire-formed pallet is provided as a load carrying
platform for storing or handling goods in a warehouse or other
facility and for shipment of unit loads via rail and truck. The
wire-formed platform of the invention is constructed to be
nestable, so that many such platforms may be stored in a minimum
space when not in use.

Description
BACKGROUND OF THE INVENTION
Most of the prior art pallets are made from wood, and although
relatively cheap, they may be easily damaged and broken. In
addition, the prior art wooden pallets are subject to contamination
and provide numerous incubation areas for the rapid growth of
bacteria. It is very difficult and costly to clean wooden pallets
because they must be handled one at a time. Wood splinters and
loose nails add to the hazards of wood pallets. Because they are
made of resinous or hardwoods, they are extremely flammable. They
are also heavy and hard to handle. Moreover, such prior art pallets
are not constructed to be nestable, so that when not in use, they
require a relatively large amount of storage space.
The wire-formed pallet of the present invention, on the other hand,
is light in weight, and also is extremely resistant to wear and
breakage. The pallet of the invention is a sturdy construction, and
is not subject to breakage. Moreover, the pallet of the invention
being made of steel wire will not absorb or retain liquids or other
contaminants and it is devoid of cracks, crevices and depressions
which serve as host areas for the breeding of various strains of
bacteria.
Unlike the prior art pallets of wood, plastic and other materials,
the pallet of this invention has no cups, pockets, steel runners or
indentations of a similar nature which tend to form collection
areas for various and sundry dirt and debris and for the retention
of water and other liquids, all of which make it practically
impossible to wash or sanitize the prior art pallets.
On the other hand, the pallet of the present invention is easily
kept in a clean and sanitary condition because it can be cleaned
and sanitized easily, quickly, and when nested. The cleansing
action of liquid or foam detergents is very efficient on the open
wire construction creating a "trickle action" and flowing by
gravity throughout all wires of the nested pallets. After a simple
water rinse, the pallets dry rapidly and are ready for use. The
pallet of the invention also provides optimum air circulation which
is of considerable value in the handling and storage of commodities
requiring refrigeration.
In accordance with the invention, a pallet is formed entirely of
wires, the wires being configured to provide a load bearing surface
displaced up from the supporting floor. The support frame for the
pallet of the invention is constituted by trusses made, in the
embodiment to be described, of steel rods, or the like which are
rigidly welded together. The particular pallet to be described is a
four-way type, and is subject to a two-way pallet truck entry, for
example, and to a four-way fork lift truck entry. The pallet frame
forms the aforesaid trusses at its top surface to form a sturdy and
strong support for the load. Also, the pallet is constructed so
that all entries for the pallet truck or fork lift truck are free
and clear of the supporting floor.
The pallet of the invention, as indicated above, is particularly
useful in warehouses, for storing or handling goods, and for
transportation of unit loads via rail and truck. The particular
pallet of the invention is also appropriate in supporting
knock-down bins, which comprise side walls formed of wires or other
material, and which may be readily mounted on the supporting pallet
to provide bins for the goods to be supported thereby.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a perspective representation of a wire-formed pallet
constructed in accordance with the invention; and
FIG. 2 is an end elevation of the pallet of FIG. 1, and it also
represents additional like pallets nested on top of one
another.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
The pallet shown in the drawing is formed of a pair of peripheral
rods 10 and 12 which, as illustrated, are shaped to define the
sides and ends of a rectangular area circumscribed by the
peripheral rods. The peripheral rods 10 and 12 are spaced from one
another, the rod 10 being disposed above the rod 12 when the pallet
is supported in a horizontal plane.
The pallet includes a plurality of transverse rods 14 which extend
from one side of the pallet to the other, and which are affixed to
the peripheral rods 10 and 12, for example, by welding. The rods 14
are supported between the peripheral rods 10 and 12, as
illustrated.
A second plurality of rods 16 extend from one end of the pallet to
the other, and these latter rods likewise are affixed, for example,
by welding to the peripheral rods 10 and 12, and are interposed
between the peripheral rods as shown in FIG. 1.
Certain of the rods 16 are configured to extend in loops out of the
plane of the peripheral rods 10 and 12 and to form supports 20 at
each corner of the pallet, and to form further supports 22 at the
center of the sides of the pallet, as well as somewhat longer
supports 24 at the center of each end of the pallet, as well as in
the center of the pallet itself.
The supports 20, 22 and 24 are shaped so that the spaces between
the supports are free and clear from the supporting surface, such
as the floor, so as to permit a two-way entry, for example, for
pallet trucks, as mentioned previously, and also to provide a
four-way entry for the usual type of fork lift truck.
Rods 16 are welded, or otherwise affixed to the rods 14, so as to
provide a rigid and stable structure. Additional straight rods 30
extend from one end of the pallet to the other, and are affixed to
the rods 10 and 12 at each end of the pallet by welding or other
appropriate means. It will be observed that the rods 16 in the
illustrated embodiment extend over the transverse rods 14, whereas
the rods 30 extend under the transverse rods 14 and are attached by
welding, or the like, to the transverse rods 14 as well as to the
respectively adjacent rods 16. The rods 30 form trusses with the
rods 14 and 16, so as to provide a sturdy and strong load
supporting surface.
Additional transverse rods 32 extend from one side of the pallet to
the other, and are configured to pass under the supports formed by
the rods 16 for reinforcing purposes. The rods 32 are attached to
the rods 16 by welding, or other appropriate means.
The invention provides, therefore, a relatively inexpensive
wire-formed pallet which is strong and sturdy, and which is not
subject to breakage. The pallet of the invention has the advantage
in that it may be easily cleaned. Also, the pallet is constructed
to permit nesting when not in use, so as to minimize the storage
requirements. The nesting of the pallet is shown in FIG. 2, in
which several pallets are represented as being nested down into one
another so as to form a compact tier.
The particular construction of the pallet is one which has
universal applicability, since the individual supports formed by
the wires is such, as described, to permit a two-way pallet truck
entry from the ends of the pallet, and a four-way fork lift entry
from the sides or ends of the pallet.
While a particular embodiment has been shown and described,
modifications may be made. It is intended in the following claims
to cover the embodiments which come within the spirit and scope of
the invention.
