Definitions

  • This invention relates to a pallet and to a method of assembly of a pallet.
  • Pallets in accordance with this invention are particularly, but not exclusively, of the kind used for transportation and storage of bulky objects, for example, transportation using fork-lift truck, trains, hoists or jacks.
  • Pallets in accordance with this invention may also be used to provide support surfaces for displays, for example, signs or posters.
  • Conventional pallets comprise ground or floor engaging bottom deck boards which may extend in a first direction, e.g. laterally, of the pallet; stringers or blocks mounted on the bottom deck boards and extending in a second direction, e.g. longitudinally of the pallet to join the deck boards; and top deck boards mounted on the stringers or blocks and adapted to carry a load in use.
  • the top deck boards usually extend parallel to the bottom deck boards.
  • Apertures between the top and bottom deck boards are adapted to receive the tines of a forklift or other lifting device or ropes which may be attached to a crane or hoist.
  • Conventional pallets are manufactured from timber joists and planks. Wooden pallets are difficult and uneconomical to repair and are usually destroyed if damaged in use. Such pallets are also bulky and difficult to transport. Nails used to fix the boards can be a safety hazard agent to the person handling the pallet or may damage the packaging of the goods being transported.
  • a pallet comprises:
  • each side rail including upper and lower runners
  • each board being adapted to extend between a runner of two of the rails;
  • each spine member including upper and lower spine runners
  • each board including a spine engaging portion adapted for sliding engagement with a spine runner; and locking means adapted when locked to prevent sliding disengagement of the boards from the spine runner;
  • each board having two ends, the ends being formed with an engagement portion; each rail having a plurality of sockets, each socket being adapted to receive and engage an engagement portion of a respective board;
  • the present invention provides a pallet which may be assembled by inserting the ends of each board with respective sockets and sliding each board in a direction parallel to the rails into engagement with the side rails. Then the spine member may be slidably engaged with the boards to form a rigid pallet capable of supporting a load in use.
  • the pallet is further capable of being dismantled for transportation, storage or repair. Reduced volumes are required for transportation of the disassembled pallet components Service inspection of the disassembled products and repair if necessary are facilitated.
  • One or more of the components, preferably the final locking member, may include an identification device, for example a radio frequency identification device (RFID) disc or label so that the pallet has a recorded identity from the production date.
  • RFID radio frequency identification device
  • the physical location may be also recorded and tracked together with the servicing record, using GPRS logistics. Locking or unlocking by movement of the boards parallel to the rails in a longitudinal direction with respect to the rails and spine member has the advantage that the components in the pallet cannot be disengaged by lateral movements, perpendicular to the rails during use.
  • the locking means Furthermore prevention of sliding movement of the boards along the spine member by the locking means provides a simple and reliable procedure for assembly and for dismantling the pallet by placing the rails in position and subsequently adding and removing the remaining components. Use of both longitudinal and transverse movements during assembly is thereby avoided.
  • each board has a tongue at each end, the tongues extending transversely of the pallet towards the sockets in the respective rails; each tongue including a formation defining an abutment extending parallel to the rail and adapted to engage a complementary formation of the rail as the board slides from the unlocked to the locked position.
  • the formation preferably comprises a slot extending parallel to the rail and dimensioned to receive a rib integral with the rail and extending towards the socket.
  • the rib is preferably a parallel sided part of the box section of the rail.
  • the formation may comprise a rib or series of projections arranged to be received in a slot in the rail.
  • Each board may have a projecting tongue or rib adapted to be slidably received and engaged within the channel.
  • Each side rail may include a plurality of inwardly extending projections and sockets located between adjacent projections, each socket being adapted to receive a board inserted between the rails and further adapted so that the board when received in the socket may be moved slidably in a direction parallel to the rail into the channels to engage the rails at each end of the board.
  • the board may have a longitudinal slot extending longitudinally of the pallet, parallel to the rail, and adapted to engage an edge of the respective runner. Such an arrangement conveniently locks the board and rails together, and is resistant to lateral or transverse movement of the rails and boards.
  • the slots or other formations of the boards extend in use parallel to the rails in a direction outwardly from the centre of the rail towards the front or rear ends of the rail.
  • the boards may be inserted into sockets and slidably moved in outward directions into their locked positions.
  • Each tongue is preferably received by sliding movement within a channel of the rail.
  • a pallet in accordance with this invention has an advantage that the rails and spine member may be formed from hollow box or tubular sections so that the rails and spine members have apertures which extend lengthwise of the pallet
  • Adjacent pallets may be fastened together end-to-end, using iope or chains to form an elongate structure
  • Such a structure may be used as a bridge in the event of flooding or to allow passage over muddy or unstable terrain
  • the pallets are composed of reinforced composite material, for example a wood reinforced polymeric composite
  • Such pallets are buoyant and may serve as safety floats or may be connected together to form a floating bridge or pontoon in the event of flooding or heavy rains
  • Pallets in accordance with this invention find applications as support surfaces for displays, for example, signs or posters, display light boxes, flooring, partitions, bed frames, table tops and benches
  • a pallet in accordance with this invention has the further advantage that it may be assembled without use of nails, screws, clips or other fixings, avoiding the need to maintain and transport a supply of the necessary number of such fixings
  • the pallet may be manufactured from extruded polymeric materials, e g polypropylene or other engineering thermoplastics, or from aluminium or other extrudable metals Use of wood-plastics composite materials is especially preferred Such materials can incorporate scrap timber and wood products Use of recycled waste wood products is particularly preferred in order to minimise environmental damage

  • Figure 24 shows the first stage of assembly of an embodiment in which lower boards
  • spine members (201 ,202, 203) provide continuous spine runners (205) comprising upwardly and downwardly pairs of ribs (206,207).
  • Protective spacers (208, 209) are inserted onto the lower spine runners between the boards (200).
  • the protective spacers provide a load bearing, smooth surface which is generally co-planer with the lower ground engaging surfaces of the boards (200). In this way damage to the spine runners and occlusion of dirt are avoided.
  • Figure 25 the above boards (210) have been inserted onto the upper spine runners (206,207) the upper boards (210) have tongues (214) with outwardly opening slots (213) extending parallel to the spine members as described with reference to the previous embodiments. Spacer boards (212) not having the slots (213) are located between pairs of boards (210). The end boards (219) may have a blind slot (213) as shown in Figure 22 to receive and engage the end of the spine member.
  • Figure 26 is a view from below the assembled pallet. In Figure 26 rails (215,216), lower end boards (218) and protective spacers (208,209,217) form a continuous planar ground engaging surface for the pallet.
  • Figure 27 illustrates an alternative segmented board in which two half portions
  • the segmented boards are advantageous in facilitating a final step of assembly of the pallet.
  • the half board portion may be inserted into a central space remaining between the two H-shaped upper board arrays after the boards have been slid outwardly into their locked positions on the rails. In alternative embodiments and modes of assembly the use of segmented boards is not necessary.
  • FIG. 28 shows an alternative locking member in accordance with this invention.
  • a central portion of the spine (300) includes a rotatable locking portion (301).
  • the locking portion may be mounted on a shaft or bearing to facilitate rotation axially of the shaft while maintaining a continuous axial cavity (302) through which a rope or other fixing may be passed in use.
  • the spine member (300) carries an upwardly extending pair of parallel ribs
  • the locking member (301) has a single upwardly extending rib or projection (306) and a single diametrically opposed downwardly facing projection (307). These may be twisted from a first position in which they are aligned parallel to the upper and lower ribs (303,304) to form a continuous surface upon which a board may slide during assembly or dismantling of the pallet, or a second locked position in which the ribs (306,307) are perpendicular so that movement of the board along the spine is prevented. Rotation of locking member may be achieved by inserting a screwdriver or other elongate tool into an aperture (308) to allow twisting of the locking member between the locked and unlocked positions.
  • Figure 29 illustrates an alternative locking arrangement wherein a spring clip is used to secure the end board to the spine member.
  • a spring clip is used to secure the board to the spine member.
  • Any convenient arrangement of spring clip may be employed to secure the board to the spine but permitting release of the board if the pallet is to be dismantled.
  • the clip has flanges extending in opposite directions on the ends to co-operate with complementary formulations on the end of the spine and underside of the board.
