Definitions

  • the common form of pallet is formulated ofplanks of wood which are nailed together to form an elevated load-carrying platform in which the elevation relative to the ground enables the forks of a lift truck to pass through the openings into the area beneath the platfonn for raising the pallet.
  • This type of pallet is heavy in that a wooden. pallet of l.20 0.80 meters will weigh about 50 kg. lnevitably, some looseness occurs at the joints as the boards or planks tend to rot and/or warp. Finally, such wooden pallets involve a definite fire hazard.
  • Pallets have also been fabricated of steel or of aluminum alloy with the same construction used to manufacture wooden pallets. Although such pallets are lighter and stronger, they are nevertheless heavy and expensive.
  • FIG. 1 is a perspective elevational view of a pallet embodying the features of this invention
  • FIG. 2 is a sectional elevational view taken along the line A-A of FIG. 1;
  • FIG. 3 is a sectional elevational view in greater detail of a portion of the upper comer of the pallet shown in FIG. 1;
  • F IG. 4 is a sectional view of the end of the thin baseplate
  • FIG. 5 is a sectional view through a pallet equipped with sling means
  • FIG. 6 is a sectional view through a modification in a pallet of large surface area having an intermediate support section
  • FIG. 7 is a sectional elevational view of a modification of the pallet illustrated in FIG. 2.
  • the material-handling pallet of this invention comprises two end sections 1 and 2, a thin base or bottom plate 3 and paneling 4 held together in the assembled relationship by a tie rod 5.
  • End sections 1 and 2 are identical and arranged at opposite ends of the pallet in facing relation.
  • End section 1 comprises a vertically disposed plate 10 of rectangular shape dimensioned to have a width corresponding to the width of the pallet and a height corresponding to the height of the top panel 4 from the base sheet 3.
  • the end plate 10 is formed with a tubular section 11 at its lower end with a slot 11 through the inner wall 11' communicating with the interior of the tubular section.
  • the tubular section may be of rectangular or other polygonal shape and dimensioned to extend through the length of the end plate 10.
  • the end plate 10 is formed with a pair of horizontally disposed lower and upper flanges 12 and 13 extending inwardly from the upper portion of the plate in vertically spaced apart relation corresponding to the height of the panel 4.
  • the end section 2 is formed of the same elements including plate 20, tubular section 21 and flanges 22 and 23.
  • the baseplate 3 is a flat plate dimensioned to correspond to the length and width of the pallet with enlarged tubular members 31 and 32 on the ends of the baseplate shaped to correspond to the tubular sections 1 1 and 21 on the end plates 10 and 20 but of lesser cross section for receipt of the tubular members 31 and 32 within the tubular sections 1 l and 21 when in the assembled relationship, with the adjacent portions of the baseplate extending through the slot openings 11.
  • the paneling 4 can be made up of sec ions or planks which are separate one from the other or of a panel formed of sheet metal, wood, or plastics, with or without corrugations.
  • the paneling 4 is dimensioned to have a length corresponding to the length of the pallet and a height corresponding to the distance between the upper and lower flanges 12-13, 22-23 with the ends 41 and 42 preferably, though not essentially, tapered to define a trapezoidal member with the base of larger dimension at the bottom.
  • the paneling can be formed with or without stiffening ribs.
  • the various components described can be fonned of the same material or of difierent materials whereby the combinations possible become numerous.
  • Suitable structural materials of which the elements are formed include metals and their alloys, plastics (with or without reinforcement), wood or wooden laminates, and the like.
  • the end sections 10 and 20 can be formed of plastic extrusions, plastic moldings or the like processes capable of producing endless lengths of such shaped products.
  • the tubular end sections 31 and 32 of the baseplate 3 are introduced into the receiving tubular sections 1 1 and 21 at the lower ends of the end plates 10 and 20. Thereafter the ends of the panel 4 are positioned with the end 41 between the flanges 12 and 13 and the end 42 between the flanges 22'and 23.
  • the components can be secured in this arrangement by suitable fastening means, such as by welding, bonding, screwing, riveting and the like, but it is preferred to effect the assembled relationship by the use of one or more tie rods 5.
  • the tie rods 5 are dimensioned to have a length greater than the distance between the end sections for passage through aligned openings 14" and 24 in the end plates within the area between the flanges but preferably nearer the upper flanges.
  • the ends of the tie rod extending through the aligned openings are threaded for threaded engagement by nut members 51 and 52 which can be tightened onto the through-extending portions of the tie rods to tighten the end plates onto the panel 4 to effect the assembled
  • the end sections When use is made of a panel 4 of trapezoidal shape, the end sections will first engage the panel at its lower edges to define pivot points 411 and 421 whereby further tightening of the nut members 51 and 52 will tend to rock the end sections for rotation about their respective pivot points with corresponding tensioning of the baseplate 3.
  • the end plates are provided with openings 15 of rectangular shape immediately below the flange 12 to enable the forks of the lift truck to be displaced therethrough in position to engage the underside of the plank 4 for lifting the pallet.
  • the lower face 131 and 231 of the upper flange 13 and 23 can be formed with a slight taper, as efi'ected by a decrease in cross section towards the free end, for camming engagement with the panel portion displaced therebetween responsive to the tightening of the nut members 51 and 52.
  • the reinforcing tubular end sections 31 and 32 on the ends of the baseplate can be formed in various ways. They can be fabricated during rolling of the sheet by the use of a roll mill having cylinders provided with corresponding grooves. Instead, they may be joined to the ends of the baseplate by welding or they may be formed integrally with the baseplate by suitable metal folding or shaping operations with the interior filled, as with a plastic material which can be foamed or cast in situ.
  • a platform plate 43 can be laid on the upper surface of the panel 4 and secured at its ends between the panel and the upper flanges 13 and 23.
  • the platform plate when used, can be a smooth continuous flat panel dimensioned to correspond to the length and width of the pallet and the platform can be grooved, corrugated and the like for strengthening purposes.
  • the pallet can be formed with a device to enable the platform to be carried by a sling.
  • the end plates 1 and 2 are fonned with outwardly extending tubular sections 14 at their upper ends with a slot 14 through the upper wall to enable a gripping member 61 of corresponding shape, on the end of a sling 6, to be displaced into the tubular section positively to engage the pallet.
  • the sling 6 may constitute wire rope and the like connected to suitable pulleys or other actuating means.
  • the lower baseplate 3 can be a single plate or panel of metal, wooden laminate or of plastic material, or it can be formed of connected parallel sections.
  • the tie rod 5 can be a single rod, as illustrated in FIGS. 1 to 4, or it can be formed of two or more lengths of rod 53 and 54, as shown in FIGS. and 6, with the rod sections connected at their adjacent threaded ends by means of an internally threaded sleeve 55.
  • the portions of the rods extending through the openings 14' in the end plates 1' and 2 can be formed with enlarged heads 56 and 57 whereby the desired tightening action is achieved by turning the sleeve 55.
  • FIG. 6 illustrates one example of a double pallet.
  • This pallet comprises two end sections 1 and 2 of the type previously described, an intermediate section 7, two panels 43 and 44, of the same construction as previously described, and one or more baseplates 3 of substantially the same construction as previously described.
  • the intermediate section 7 is formed with a flange or pedestal 71 arranged to rest on an intermediate surface of the baseplate 3.
  • the intermediate section is formed with two vertically spaced lefthand flanges 731 and 721 adapted to receive the right-hand end of panel 43 and two vertically spaced right-hand flanges 732 and 722 adapted to receive the left-hand end portion of panel 44. Assembly and tightening are carried out by conventional means, but preferably with the aid of a tie rod which may be either of the construction described with reference to element 5 in FIG. 2 or as shown in FIG. 6.
  • the enlarged tubular end sections 31 and 32 of the baseplate 3 are engaged in their respective slideways 11 and 23 of the end sections 1 and 2. Thereafter, the intermediate section 7 is positioned with its flange 71 resting on the baseplate 3. Finally the ends of the panel 43 are positioned with the left-hand end between flanges 12 and 13 of section 1 and the right-hand end between the flanges 721 and 731 of section 7. The same arrangements are made with the panel 44 in which the left-hand end is positioned between flanges722 and 732 of section 7 while the right-hand end is positioned between the flanges 22 and 23 of section 2. All that remains is to position and tighten the tie rods 53, 54 until the whole assembly is interlocked.
  • the intermediate section 7 isformed to employ the action of web against web confined by the two flanged sections, with the two slideways such as 11 being replaced by a flange 71 which rests on the baseplate. It is also possible to provide the intermediate section with two slideways, one to the right and the other to the left, for use with two baseplates corresponding in construction to the baseplate 3. In this way, it is possible similarly to obtain a pallet formed by the arrangement of two pallets of the type shown in FIG. 2 in side by side relationship, the intermediate sections merely being combined into a single intermediate symmetrical section. It is obvious that pallets of large surface area may be obtained by similar arrangement of more than two single pallets.
  • the panel 4 is in the form of a prestressed arch which is obtained by placing the assembly and interlocking means 5 under high tension, either by tightening the nut members 51 and 52 in FIGS. 1 to 3, or by tightening the threaded sleeve 55 in the modification shown in FIGS. 5 and 6.
