Definitions

  • the invention concerns a pallet consisting of a number of parallel stringers and a deck surface formed by deck elements fitted at right angles to the stringers at distances one from the other the stringers being constructed of at least two rectangular parallel plates arranged predominantly vertically and joined to each other and having recesses at their top into which the deck elements fit closely.
  • a pallet of this kind is described in DE-A-2032220.
  • a drawback of this pallet is that the fastening of the deck elements to the stringers is rather difficult due to the small contact surfaces between them.
  • From US-A-3058709 a pallet is known whereby the deck elements lie in the recesses of rather heavy stringers. Due to their heaviness these stringers are not suitable to be made of plastics material.
  • the pallet has to be inexpensive, preferably so inexpensive that it can be used as a one-way or expendable pallet.
  • the pallet has to be light with a view to ease of handling and because of transport costs.
  • it In the third place it must have a loading capacity such that fairly heavy loads of, for example, 1000 kg are possible without causing the deformation of the pallet to increase beyond acceptable limits.
  • a large number of other requirements specified can usually also be met without much difficulty.
  • the dimensions can be altered as desired or measures can be taken to enable the pallet to be used for a particular application.
  • the invention concerns a pallet which satisfies the three main conditions mentioned, while at the same time, on the basis of the original form of the pallet, the use of present- day technical possibilities enables an entirely new and surprising pallet design to be offered.
  • connection between the plates consists of transverse partitions which are vertically arranged immediately beside the recesses.
  • the stringers with the transverse partitions and recesses will preferably be made of plastic in one piece by injection moulding.
  • the thickness of the material and the sizes of the plates and partitions can be adjusted as desired, as also can the plastic to be selected.
  • With regard to the length of the stringers the requirements to be met can be easily satisfied by making use of an adjustable mould.
  • the number of stringers will depend on the size of the pallet but is usually three. Smaller pallets can be made with only two stringers.
  • transverse partitions should extend over the whole height of the plates to ensure that the plates do not buckle under a load.
  • the arrangement of the transverse partitions immediately beside the recesses makes it possible to fasten the deck elements to be inserted in the recesses to the transverse partitions and hence to the stringers with glue or staples or with the aid of snap-in fastenings.
  • the transverse partitions may, with a view to saving material, but also in order to make fastening of the deck elements on two sides possible, be fitted alternately to opposite sides of the recesses in adjacent spaces between the plates. Greater stability of the deck elements is thus obtained.
  • the deck elements may be supported by all the stringers. It is, however, also possible for a deck element to span fewer stringers.
  • the first version is preferable for reasons of stability and production.
  • a stringer consisting of four plates with a number of alternately arranged transverse partitions alongside the recesses is in many cases of sufficient strength to take usual loads.
  • the deck elements are of rectangular cross-section and are arranged so that their narrow sides form the load-bearing surface of the pallet.
  • the pallets with recesses in them can be made of plastic integrally with the transverse partitions by injection moulding.
  • the deck elements will be preferably made of another material possessing greater rigidity.
  • the chief materials in mind are wood and board, of which wood deserves preference because of its deflection properties and the fact that wood is more resistant than board to the effects of moisture.
  • Fig. 1 shows stringers marked 1, 2 and 3 of a pellet and deck elements marked 4. To bring out the recesses more clearly in the drawing some deck elements have been omitted.
  • Every stringer consists of four rectangular plastics plates 6, 7, 8 and 9, arranged predominantly vertically, with recesses 5 made in their upper sides; see Figs. 1 and 4.
  • transverse partitions 10 are fitted over the full height of the plastics plates. The ends of the stringers are fitted with end plate 11.
  • Transverse partitions 10 are fitted in such a way that they are located in gaps 12, 13 and 14, alternately immediately next to one of the sides of the recesses. The deck elements inserted in the recesses are thus better supported on both sides.
  • the wooden deck elements which have a rectangular cross-section are placed so that their narrower sides form the load-bearing surface of the pallet. This means that the fullest possible advantage is taken of the rigidity properties of the material of which the load-bearing (deck) elements consist. These load-bearing elements may be completely recessed into the stringers or project slightly above them.
  • the load-bearing elements are fastened to the stringers by stapling them to the adjacent transverse partitions as shown by 15 in Fig. 5. They can also be fastened by gluing or with the aid of snap-in fastenings.
  • the long sides of the plates have openings 16 and 17 to make entry by the fork of the fork-lift truck possible.
  • the stringers were made of low-density polyethylene.
  • the plates and transverse partitions were 3 mm thick. Wooden deck elements with cross-section dimensions of 32 x 10 mm were placed in the recesses. The dimensions of the pallet were 1200 x 800 mm. The total weight of the pallet was 5.8 kg, of which 1.4 kg was accounted for by the wood.
  • the pallet was tested using a fork-lift truck for lifting and laying, the DIN 32600 as guideline, the width of the truck forks being 100 mm and the centre distance between the forks 575 mm.
  • the load was 600 kg, distributed evenly over the pallet. The deflection in the middle and at the outside of the pallet was found to be 3.5 mm.
