Abstract

A load-handling pallet includes a load bearing platform, a base member, and a plurality of block elements. The block elements are arranged to interconnect the load bearing platform to the base member. In one embodiment, snap-fit connections are provided between the block elements and both the platform and the base member. The snap-fit connections are arranged to be engaged by a movement perpendicular to the plane of the platform. The snap-fit connection is facilitated by inserting spigots, projecting from opposing sides of the block elements, within apertures formed in the platform and base member.

Claims

1. A load-handling pallet which comprises:

(a) a load-bearing platform having a bottom surface with a plurality of apertures formed thereon and a peripheral groove at least partially encircling each aperture,

(b) means defining a base member, and

(c) at least four block elements arranged to interconnect the platform and the base member, each block element including a collar attached to and at least partially encircling an upward facing spigot, one end of the collar terminating at a top edge, each upward facing spigot being directly received in a snap-fit connection within a corresponding aperture of the load bearing platform such that the top edge of the corresponding collar is received within the peripheral groove encircling the corresponding aperture, the snap-fit connections being arranged to be engaged by a movement perpendicular to the plane of the platform.

2. A pallet as claimed in claim 1, in which the platform comprises a plurality of releasably connected components of plastics material.

3. A pallet as claimed in claim 1, in which the connections between the block elements and both (a) the platform and (b) the base member are provided by snap-fit connections.

5. A pallet as claimed in claim 1, wherein each peripheral groove and each top edge of the collars have complementary polygonal configurations.

6. A pallet as claimed in claim 1, in which each block carries two spigots extending in opposite directions, for engaging the platform and the base member respectively.

7. A pallet as claimed in claim 6, further comprising a plurality of apertures formed on the base member and a peripheral groove at least partially encircling each aperture, each aperture on the base member being configured to snap-fit connect with the spigot of a corresponding block element.

8. A pallet as claimed in claim 1, in which the platform comprises a plurality of decking boards and at least two crossmembers on which the decking boards are supported.

9. A pallet as claimed in claim 8, in which the apertures of the load bearing platform are formed on the crossmembers.

10. A pallet as claimed in claim 9, in which the apertures in the crossmembers are arranged so that the ends of the spigots do not protrude above the upper surfaces of the crossmembers.

11. A pallet as claimed in claim 9, in which the decking boards cover the apertures in the upper surface of the crossmembers.

12. A pallet as claimed in claim 9, in which the decking boards engage the crossmembers by means of mating dove-tail portions, the decking boards and the crossmembers having mating dimple elements and pips at their crossing points.

13. A load-handling pallet as recited in claim 1, wherein the loadbearing platform includes a pair of spaced apart walls projecting from the bottom surface thereof, the pair of spaced apart walls bounding at least a portion of the peripheral groove therebetween.

4. A pallet as claimed in 1, in which the collar of each block element also at least partially encircles a downward facing spigot.

14. A load-handling pallet comprising:

(a) a load bearing platform having a bottom surface with a plurality of apertures formed therein, a peripheral groove at least partially encircles each of the apertures on the bottom surface of the platform;

(b) a base frame integrally molded as a single unit from a material comprised of plastic, the base frame having a plurality of apertures formed therein; and

(c) a plurality of space blocks each having a tubular collar attached to and at least partially encircling an upward facing spigot and a downward facing spigot, one end of the tubular collar terminating at a top edge, each upward facing spigot being configured to be received in a snap-fit connection within a corresponding aperture of the load bearing platform such that the top edge of the corresponding collar is received within the peripheral groove encircling the corresponding aperture, each downward facing spigot being configured to be received within a corresponding aperture of the base frame such that each downward facing spigot directly interlocks with the base frame in a snap-fit connection.

15. A load-handling pallet as recited in claim 14, wherein the load bearing platform comprises:

(a) a plurality of elongated stringers each having a bottom surface with the apertures formed therein and a top surface having a plurality of dove-tail grooves formed thereon; and

(b) a plurality of deck boards, each deck board being configured to slide within a corresponding dove-tail groove.

16. A load-handling pallet as recited in claim 15, wherein each elongated stringer is integrally molded as a single unit from a material comprised of plastic.

17. A load-handling pallet as recited in claim 14, wherein each peripheral groove and each top edge of the tubular collars have complementary polygonal configurations.

18. A load-handling pallet as recited in claim 14, wherein each tubular collar terminates at an opposing bottom edge and each aperture on the base frame is at least partially encircled by a peripheral groove, the bottom edge of the each collar being received within a corresponding peripheral groove on the base frame when a corresponding downward facing spigot is received within the corresponding aperture.

19. A load-handling pallet comprising:

(a) a plurality of elongated stringers each having a bottom surface and an opposing top surface, the top surface having a plurality of dove-tail grooves formed thereon, the bottom surface having a plurality of apertures formed thereon, each aperture being at least partially encircled by a peripheral groove;

(b) a plurality of space blocks mounted to the bottom surface of the elongated stringers, each space block including a collar attached to and at least partially encircling an upward facing spigot, one end of the collar terminating at a top edge, each upward facing spigot being received in a snap-fit connection within a corresponding aperture of the stringer such that the top edge of the corresponding collar is received within the peripheral groove encircling the corresponding aperture; and

(c) a plurality of deck boards, each deck board being configured to be slideably received within corresponding dove-tail grooves on the stringers.
