Abstract

A winch assembly includes a base having first and second sides, a first shaft supported by the base and supporting a gear and a reel, and a second shaft supported by the base and supporting a ratchet gear. The ratchet gear meshes with the gear and a pawl, and a handle is attached to the second shaft for rotation thereof. The winch includes a cover having a top movable between first and second positions and first and second sides rotatably supporting the top. The first side may include a first arm extending toward and engaging a second arm extending from the second side. The top may include hooks for engaging a shaft extending between the sides of the cover. The sides of the cover may each include at least one retainer clip and the top includes corresponding lugs for engaging the at least one retainer clips.

7. The winch assembly of claim 3, wherein the arm supports an insert for receiving a bolt extending through the second side of the cover for securing the first and second sides of the cover together.

8. The winch assembly of claim 7, wherein the second side of the cover includes a second arm extending toward the first side of the cover and the arm includes a nib extending toward the second arm and the second arm includes a pocket for receiving the nib.

9. The winch assembly of claim 7, wherein the upper member of the cover includes at least one hook engaging the bolt.

10. The winch assembly of claim 1, wherein the upper member of the cover includes a pair of hooks for engaging a third shaft extending between first and second sides of the cover.

11. The winch assembly of claim 1, wherein the pawl includes a lever and further comprising a cover for the lever, the cover extending at least partially through an aperture formed in the upper member of the cover when the cover is in a closed position.

12. A winch assembly including a base supporting a reel and a gear on a first shaft, a ratchet gear on a second shaft meshing with the gear for rotating the reel, a pawl for engaging the ratchet gear, and a handle attached to the second shaft, comprising:

a cover including first and second sides and a top rotatable between first and second positions relative the first and second sides.

13. The winch assembly of claim 12, wherein the first side includes a first arm extending toward and engaging a second arm extending from the second side.

14. The winch assembly of claim 13, wherein the first arm includes an aligner extending toward the second arm for engaging an aperture formed in the second arm.

15. The winch assembly of claim 12, wherein the top includes at least one hook for engaging a third shaft extending between the first and second sides.

16. The winch assembly of claim 15, wherein the third shaft is supported by the first and second arms.

17. The winch assembly of claim 16, wherein the shaft is a bolt extending through the first side and a channel formed in the first arm and engaging a threaded insert supported by the second arm.

18. The winch assembly of claim 12, wherein the first side includes at least one retainer clip and the top includes at least one lug.

19. The winch assembly of claim 18, wherein the second side includes at least one retainer clip and the top includes at least one additional lug.

20. A winch assembly, comprising:

a base having first and second sides;

a first shaft supported by the base and supporting a gear and a reel;

a second shaft supported by the base and supporting a ratchet gear, the ratchet gear meshing with the gear and a ratchet and pawl supported by a third shaft supported by the base;

a handle attached to the second shaft for rotating the second shaft; and

a cover having a top movable between first and second positions relative first and second cover sides rotatably supporting the top.

21. The winch assembly of claim 20, wherein the first side includes a first arm extending toward and engaging a second arm extending from the second side along an end of the base.

22. The winch assembly of claim 21, wherein the first arm includes a nib for engaging an aperture formed in the second arm.

23. The winch assembly of claim 20, wherein the top includes first and second hooks for engaging a fourth shaft extending between the first and second sides of the cover.

24. The winch assembly of claim 23, wherein the fourth shaft is a bolt extending through a channel formed in the first arm into an insert supported by the second arm.

25. The winch assembly of claim 20, wherein the first and second sides of the cover each include at least one retainer clip and the top includes corresponding lugs for engaging the at least one retainer clips.
