PALLET FOR STORING AND TRANSPORTING GOODS
The present invention relates to a pallet for storing and transporting
goods.
Wooden pallets are known for storing and transporting goods. They
present a series of drawbacks, and in particular:
- they have a large weight (25-26 kg if the wood is dry), often comparable
with the weight of the goods placed on them,
- they require the use of costly equipment for their construction, resulting
in
an added cost to the transported product.
An object of the invention is to eliminate these drawbacks by
providing a pallet for storing and transporting goods which is of simple and
automated construction, using traditional methods and plants.
Another object of the invention is to provide a pallet which presents
characteristics suitable for international transport and conforms to the FAO
Standard, even without accompanying documentation.
Another object of the invention is to provide a pallet which can be
formed in accordance with patterns corresponding to different requirements.
All these and further objects which will be apparent from the ensuing
description are attained according to the invention by the pallet defined in
claim 1. .
The present invention is described in detail. hereinafter with reference
to the accompanying drawings, in which:
Figure 1 is a perspective view of a pallet according to the invention,
Figure 2 is an enlarged partial perspective view thereof,

Figure 3 is an enlarged detailed view of a support portion,
Figure 4 shows a different enlarged detailed view of a support portion, and
Figure 5 is a vertical section through a pallet of the invention taken through
the cut-out holes provided in the supports.
As can be seen from the figures, the pallet of the invention comprises
substantially a load platform 2 of sheet metal supported by three tubular
supports 4 of U cross-section disposed parallel to each other along the
longitudinal edges and along the centre line of the platform 2.
The platform 2 comprises a plurality of continuous parallel grooves 6
substantially of V cross-section with their axis perpendicular to the axis of
the
supports 4.
Those edges 8 of the platform 2 parallel to the grooves 6 are bent
downwards to facilitate the operations involved in loading the pallet and to
create a bevel with an anti-cutting function; alternatively, those edges 8 of
the platform 2 parallel to the grooves 6 can be bent upwards to perform a
containing function.
The upper surface of the platform is made rough or provided with a
plurality of centering ribs or projections 10 disposed in a circular or square
pattern. They can be obtained by drawing the sheet metal forming the
platform or be formed separately and applied thereto.
The platform is formed from a single piece of sheet metal, but could
also be formed in several parts joined together by seam-joining, welding,
adhesive-bonding or crimping.

WO 2006/061183 PCT/EP2005/013045

The side walls 12 of each support 4 comprise continuous parallel
grooves 16 performing a stiffening function. A similar stiffening function is
performed by ribs 18 provided on the base 14 of the support, the lower
surface of which is covered with anti-slip material or is made rough.
The upper edge of the side walls 12 of each support 4 comprises V-
shaped recesses 20, complementary to the grooves 6 of the platform 2, both
ends of the base 14 of each support comprising a bevel 15.
The side walls 12 of the tubular supports 4 comprise cut-out holes 22
for engagement by the prongs of a lifting fork. The cut-out holes 22
generally have a height less than the height of the side wall 12 of the
support
4, i.e. each cut-out hole 22 is bounded lowerly and upperly by a strip of the
side wall 12 of the support. In addition, in order to facilitate fork
insertion,
the lower edge 24 of each cut-out hole lies at a level slightly lower than the
crest of the ribs 18 provided on the base 14 of each support 4. Again to
facilitate fork insertion, the lower edge of each cut-out hole and the crest
of
those ribs closest to it are connected together by an inclined surface 23
preferably obtained by bending a strip of the sheet metal portion
corresponding to the cut-out hole.
As generally each cut-out hole 22 is preferably obtained by cutting
the sheet metal forming the side wall of the support 4, the cut sheet metal
portion, instead of being completely removed, is preferably bent upwards
through 90 and fixed to the lower surface of the platform 2, to form a
reinforcement element for the platform at its most highly stressed parts.

Further reinforcement elements comprise profiled plates 26 inserted
into the tubular supports 4 at those portions not comprising the cut-out
holes.
These reinforcement elements are fixed to the side walls 12 and to the base
14 of the respective supports 4, and to the platform 2.
These reinforcements are made of sheet metal bent several times in
order to involve a certain length of the support and are provided in both
horizontal edges with recesses 28 and 30 complementary to the grooves 6 of
the platform and to the ribs 18 of the base 14 of the respective support 4.
The recesses 30 preferably have larger dimensions than the corresponding
ribs 18 to allow passage of liquids accidentally spilled and/or used to wash
the pallet.
Further reinforcement elements comprise terminal plugs 32 applied to
the ends of each support and preferably consisting of portions of the sheet
metal of the platform and/or support bent towards the interior of the support.
To further stiffen the structure of the pallet of the invention, adjacent
supports 4 can also be connected together at floor level by ties 34
permanently or removably applied between the facing side walls 12 of
adjacent supports 4.
To construct the pallet of the invention, the platform 2 ands the
supports 4 can be formed separately of sheet metal then, after inserting and
fixing the reinforcement elements 26, 32 into the supports 4, be joined
together by seam-joining, welding, riveting, clinching, adhesive-bonding, etc.
The platform itself can be made in one piece or be formed by joining
several parts together by seam-joining or riveting or welding or crimping.

CA 02589728 2007-05-29
WO 2006/061183 PCT/EP2005/013045
The pallet can also be obtained by bending and profiling a sheet
metal web to form the platform and the three supports, or to form the
platform and the outer supports, between which the inner support can then
be fixed to the platform.
5 From the aforegoing it is apparent that the pallet of the invention
presents numerous advantages, namely:
- it is of lower weight (less than 9 kg) for equal performance (static
capacity
and dynamic capacity),
- it can be easily produced by known machines and techniques (drawing
presses, bending machines, profiling machines),
- it has the same dimensions as wooden pallets and can hence be used for
the same purposes,
- it can also be used as a removable floor to be maintained on a previously
erected frame,
- it can be engaged and lifted as required, by forks inserted below the
platform both parallel and perpendicular to the axis of the supports.
- finally, instead of being constructed of sheet metal, the pallet can be
constructed entirely of plastic material.
