Definitions

  • This invention relates to a pallet comprising a planar load bearing surface and to an assembly of pallets.
  • the invention also relates to a method for assembling pallets.
  • Pallets for supporting and moving various types of articles are well known in the art. Pallets may be made from different materials, including wood, metal, fibreglass, composite materials or plastic, depending on the intended use and operating environment. Pallets are generally provided with a planar load bearing surface and are adapted for use with several types of loading equipment such as cranes, forklifts or other specialised equipment. When not loaded, pallets take up a lot of floor space and may be stored in a stacked configuration, as shown for example in US5606921. These stacks are however often unstable and/or damage of the stacks during transportation may occur.
  • WO92/01607 describes a pallet having a load bearing surface comprising two sections with interlocking protrusions which mate to receive a releasable locking member, wherein the protrusions are small with respect to the total load bearing surface in order to obtain a larger pallet when the two sections are assembled to receive for example a bulky load.
  • the pallets according to the state of the art therefore have a configuration giving considerable storage and transportation problems when the pallet is not loaded.
  • the pallet is being provided to receive second elements of a second such pallet in the recesses such that the load bearing surfaces of the first and second pallet lie in substantially the same plane.
  • a pallet having such a configuration allows for a simple space-saving storage when the pallet is not loaded.
  • the pallets are placed such that the second elements and the recesses of a first complementary pallet can engage with complementary recesses and second elements of a second complementary pallet, creating a pallet assembly taking up much less floor space than the pallets taken separately.
  • the second elements are of a shape and size so that the second elements can be inserted in the recesses of a second pallet and will be for example secured by the frictional forces created from the contact of the outer surface of the second elements and the inner surface of the recesses.
  • the pallet is delimited by a first side and a second side.
  • the first side is a longitudinal side and the second side is a lateral side.
  • Pallets having a longitudinal side and a lateral side are most commonly used in logistics, since the longitudinal side and the lateral side define a versatile planar load bearing surface which allows for a convenient placement and transport of goods. More preferably, the load bearing surface has a rectangular shape, since pallets having this shape are most commonly used in transportation and shipping worldwide and are therefore compatible with existing storage facilities, transportation equipment and the standards in use.
  • the first element extends in a direction along the first side.
  • At least one of the second elements extends in a direction along the second side.
  • the second elements are tapered.

  • the second elements 4 and recesses are shown as being generally tapered, other shapes such as rectangles, trapezoids, such as right and/or isosceles or triangles may also be used.
  • second elements 4 Although six second elements 4 are shown in Figure 1 , it can be appreciated that fewer or more elements may be utilized. Many different combinations and permutations of the number, shape and position of the second elements 4 are contemplated by the present invention.
  • perforations 13 are preferably present in the second elements 4. Such perforations 13 are an advantageous feature and render the pallet for example lighter without seriously compromising the strength of the pallet 1 and avoid the accumulation on the pallet 1 of for example liquids, which may leak from the load bearing surface 2 or even increase the load.
  • the perforations 13 may also be used for anchoring the upwardly extending storing means 1 1 on the pallet 1. Perforations may for example also be present for anchoring purposes on side panels which may be mounted on the pallet 1.
  • the pallets are delimited by a first side 6 and a second side 7, in particular a substantially straight lateral and longitudinal side.
  • Such delimited pallets when placed side by side, allow for a space saving arrangement on the floor.
  • two forklift passages 8 are present in the first element 3 and extending along the second elements 4 (see Figures 1 and 2) and/or in the second elements 4 and extending along the first element 3 (see Figures 3-8).
  • Such a configuration allows for the insertion of the arms of a forklift, pallet jack or other lifting device commonly used in the art.
  • Most forklifts or pallet jacks commonly used in the art use two arms to properly balance a pallet.
  • the pallets configured as shown comprise forklift passages 8 extending all the way through a side of the pallet, allowing for the forklift arms to be inserted from 2 opposite sides of the pallet, although such a feature is not a necessary element of the invention.

  • Suitable connection means include but is not limited to nuts and bolts, a click system, hooks, snap-fit connection etc. Because different loads are stored on the pallets during different shipments, it is advantageous to be able to shift the position of or detach or fold the upwardly extending load storing means 1 1. Different combinations of shapes, positions and sizes of the upwardly extending load storing means 1 1 are within the scope of the present invention. In preferred embodiments illustrated in Figures 3 and 5-8, certain upwardly extending load storing means 1 1 form a framework construction.
  • This framework construction is of particular interest for the storing and keeping intact of valuable and/or vulnerable uniform pieces of equipment such as automotive parts, such as car parts in a space saving manner. Illustrated in the figures is a framework construction with in the four corners of the pallet vertical support members and in between horizontal connecting members. Additional accessories may be attached to the framework construction to contribute to this aim, as illustrated in Figures 5-8. These accessories may include for example cushioned mounting supports for supporting fragile pieces of equipment.
  • the upwardly extending load storing means do not hinder the assembly of the pallet when unloaded and when engaging the second elements and the recesses of a first complementary pallet with complementary recesses and second elements of a second complementary pallet.
  • the configuration of the upwardly extending load storing means could for example be such that when sliding two pallets together, the upwardly extending load storing means are too bulky /andor get entangled and hinder second elements to be inserted into the recesses. Possible solutions to this problem are for example folding away, dismounting or removing the upwardly extending load when the pallets are unloaded and ready for assembling.
  • the pallets 1 are stackable, as illustrated in Figures 7 and 8.
  • the upper sections of the framework construction in this particular example the upper section of the vertical support member engages with the underside of the pallet 1 , for example with a recess, groove or receptacle present on the underside of the pallet for keeping the pallets securely stacked and preventing the sliding or any other undesired movement of the pallet.
  • the stacking of the pallets sets more stringent requirements for the selection of the materials of the framework construction, depending on the weight of the loads and the number of pallets that is to be stacked.
  • several pallets 1 may be securely stacked together, optionally using for example ties or ropes, so that the stack may be transported or moved without the individual pallets separating or falling apart and taking up less floor space.
  • Two or more unloaded pallets 1 can be assembled into a pallet assembly 12, wherein the second elements 4 of the first pallet 1 mate with complementary recesses 5 in the second pallet 1.
  • Illustrative embodiments of such assemblies 12 are shown in Figures 2, 6 and 8.
  • the second elements 4 and recesses 5 are all of the same shape and size for each pallet assembly 12.
  • not all second elements/recess 4,5 combinations need to be identical, and the shape and size may differ for one combination to another both in the same pallet 1 and in different embodiments of the pallets 1.
  • the method for assembling an assembly 12 of pallets 1 is illustrated in Figure 3. To assemble such pallets 1 when unloaded the pallets may be placed such that the second elements 4 of the first pallet 1 engage with the recesses 5 of the second pallet.
  • the two pallets can for instance slide together until the assembly is formed and this sliding together can be facilitated by the tapered shape of the second elements 4, since it offers a wider opening at the onset of the recess 5 to mate with a second element 4 which is smaller at the extremity.
  • the pallets 1 may be separated by applying a separating force between them.
  • the component pallets 1 are then pried, pulled or otherwise taken apart. This may be done by holding one portion in place while applying a force to the other portion.
  • Simple tools such as a hammer, a crowbar or other similar devices may be used to assist in the separation of the pallets from each other.
