Abstract

A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.

First claim

What is claimed is:

1. A pallet sled comprising:
a lower frame;
an upper frame;
a plurality of pivot arms pivotably connecting the upper frame to the lower frame, wherein the upper frame is movable between a lowered position and a raised position, wherein the upper frame is spaced further from the lower frame in the raised position than in the lowered position, and wherein the upper frame is configured to rotate slightly relative to the lower frame when moved from the lowered position to the raised position.

2. The pallet sled of claim 1 wherein the upper frame and the lower frame each include a pair of spaced-apart arms and each are open outwardly to receive feet of a pallet.

3. The pallet sled of claim 2 further including a lift mechanism for selectively moving the upper frame from the lowered position to the raised position.

4. The pallet sled of claim 3 wherein the plurality of pivot arms includes outer pivot arms connecting the pair of spaced-apart arms of the upper frame to the pair of spaced-apart arms of the lower frame.

5. The pallet sled of claim 4 wherein the plurality of pivot arms further includes inner pivot arms connecting the pair of spaced-apart arms of the upper frame to the pair of spaced-apart arms of the lower frame, wherein the inner pivot arms are inward of the outer pivot arms.

6. The pallet sled of claim 5 wherein the outer pivot arms are longer than the inner pivot arms.

7. The pallet sled of claim 6 wherein the upper frame rotates approximately 1.5 to approximately 2.0 degrees when the upper frame is moved from the lowered position to the raised position.

8. The pallet sled of claim 7 wherein the pair of spaced-apart arms of the upper frame are less than or equal to approximately 38″ long.

9. The pallet sled of claim 5 wherein the outer pivot arms and the inner pivot arms are configured to tilt the upper frame relative to the lower frame when the upper frame is moved from the lowered position to the raised position.

10. The pallet sled of claim 9 further including wheels supporting the lower frame.

11. The pallet sled of claim 10 further including a base and a vertical handle at an inner end of the lower frame.

12. The pallet sled of claim 11 wherein the lift mechanism is manual, hydraulic, electric or electrohydraulic.

13. A pallet sled comprising:
a lower frame;
a plurality of wheels supporting the lower frame;
an upper frame;
wherein the upper frame is movable relative to the lower frame between a lowered position and a raised position, wherein the upper frame is spaced further from the lower frame in the raised position than in the lowered position, and wherein the upper frame is configured such that when the upper frame is in the raised position the upper frame tilts approximately 1.5 to approximately 2.0 degrees relative to a floor on which the plurality of wheels would contact.

14. The pallet sled of claim 13 further including a plurality of pivot arms pivotably connecting the upper frame to the lower frame, wherein the plurality of pivot arms are configured to cause the upper frame to be tilted approximately 1.5 to approximately 2.0 degrees relative to the floor on which the plurality of wheels would rest.

15. The pallet sled of claim 13 further including a generally vertical handle portion extending upward from the lower frame, wherein the upper frame is configured to tilt toward the generally vertical handle portion when the upper frame is in the raised position.

16. A method for lifting a pallet including the steps of:
a) moving upper arms of a pallet sled under a deck of the pallet resting on a floor, while the upper arms are in a lowered position; and
b) after said step a), raising the upper arms from the lowered position to a raised position to lift the pallet off the floor and rotating the upper arms relative to the floor to tilt the pallet relative to the floor.

17. The method of claim 16 wherein the pallet is tilted approximately 1.5 to approximately 2.0 degrees in said step b).

18. A pallet and a pallet sled comprising:
the pallet sled including a lower frame, a plurality of wheels supporting the lower frame, and an upper frame, wherein the upper frame is movable relative to the lower frame between a lowered position and a raised position, wherein the upper frame is spaced further from the lower frame in the raised position than in the lowered position, wherein the upper frame is approximately 29 inches to approximately 38 inches long; and
the pallet including a deck supported by feet, wherein the deck is supported on the upper frame of the pallet sled, wherein the deck of the pallet is approximately 48 inches long.

19. The pallet and pallet sled of claim 18 wherein the upper frame is approximately 29 inches long.

20. The pallet and pallet sled of claim 18 wherein the upper frame is approximately 38 inches long.

21. The pallet and pallet sled of claim 19 wherein the upper frame is tilted approximately 1.5 to approximately 2.0 degrees relative to a floor on which the plurality of wheels are supported when the upper frame is in the raised position.

22. The pallet and pallet sled of claim 18 wherein the upper frame is tilted approximately 1.5 to approximately 2.0 degrees relative to a floor on which the plurality of wheels are supported when the upper frame is in the raised position.

23. The pallet and pallet sled of claim 18 wherein the pallet sled further includes a pair of outer pivot arms and a pair of inner pivot arms connecting the upper frame to the lower frame, wherein the outer pivot arms are longer than the inner pivot arms.

24. The method of claim 13 wherein the plurality of pivot arms includes outer pivot arms and inner pivot arms and wherein the outer pivot arms are longer than the inner pivot arms to rotate the upper frame relative to the floor.

25. The method of claim 14 wherein the plurality of pivot arms includes outer pivot arms and inner pivot arms and wherein the outer pivot arms are longer than the inner pivot arms to rotate the upper frame relative to the floor.

26. The method of claim 16 wherein the upper arms are pivotably connected to outer pivot arms and inner pivot arms, wherein the outer pivot arms are longer than the inner pivot arms to rotate the upper arms relative to the floor.
