Abstract

Methods and systems are provided for a winch including a rotatable tie structure. In one example, a winch may include a tie structure coupled to a top side of a winch. Notches formed in main cross rails of the tie structure enable rotation of the tie structure relative to a housing of the winch.

First claim

The invention claimed is:

1. A winch, comprising:
a housing including a first drum support and a second drum support;
a drum rotatable about a central axis, a first end of the drum supported by the first drum support and a second end of the drum supported by the second drum support; and
a tie structure positioned directly above and extending across the drum, between the first and second drum supports and from a first to second end of each of the first and second drum supports, where the tie structure is rotatable about a rotational axis arranged at a first side of the tie structure that extends across the drum from the first drum support to the second drum support.

2. The winch of claim 1 , wherein the rotational axis is parallel to and positioned vertically above and offset from the central axis and wherein the tie structure is coupled to only the first and second drum supports and no other winch components.

3. The winch of any of claim 1 , wherein the tie structure extends across the drum, from the first drum support to the second drum support, in a direction parallel to the central axis, and wherein the tie structure extends across the drum, along a length of each of the first drum support and second drum support, in a direction perpendicular to the central axis, where the width length is defined between the first side and second side of each of the first and second drum supports, and where the first and second sides are arranged opposite one another across the central axis.

4. The winch of claim 1 , wherein the tie structure includes two main side rails and two main cross rails, where the two main side rails are each coupled to and between the first and second drum supports and separated from one another across a width of the winch and where the two main cross rails are each coupled to and between each of the two main side rails and extend along the width of the winch.

5. The winch of claim 4 , wherein a first main cross rail of the two main cross rails is coupled directly to and extends across an inner surface of the first drum support and wherein a second main cross rail of the two main cross rails is coupled directly to and extends across an inner surf ace of the second drum support.

6. The winch of claim 4 , wherein a first main side rail of the two main side rails forms the first side of the tie structure and the tie structure is rotatable about the first main side rail and wherein each of the two main cross rails, at an end of each of the two main cross rails that is coupled to the first main side rail, includes a notch.

7. The winch of claim 4 , wherein a first main side rail of the two main side rails forms the first side of the tie structure, wherein a second main side rail of the two main side rails forms a second side of the tie structure, wherein the tie structure is rotatable about the first main side rail and the second main side rail, and wherein each of the two main cross rails include a notch at a first end that is coupled to the first main side rail and at a second end that is coupled to the second main side rail.

8. The winch of claim 4 , wherein the tie structure further includes a first additional cross rail and a second additional cross rail separated from one another and coupled between the two main side rails, wherein the tie structure includes a central opening formed by the first and second additional cross rails and the two main side rails, and wherein the tie structure includes two secondary openings, smaller than the central opening, each of the two secondary openings formed between one of the first and second additional cross rails and one of the two main cross rails.

9. The winch of claim 4 , wherein the tie structure includes a plurality of mounting apertures arranged in the two main side rails and further comprising a control unit removably coupled to a top, outer surface of the tie structure via the plurality of mounting apertures.

10. The winch of claim 6 , further comprising a fairlead fastened to a front of the winch and wherein the first main side rail is positioned at the front of the winch.

11. The winch of claim 6 , further comprising a fairlead fastened to a front of the winch and wherein a second main side rail of the two main side rails is positioned at the front of the winch.

12. The winch of claim 6 , wherein the drum includes a cylindrical portion disposed between a first drum flange and a second drum flange, the first drum flange disposed within and supported by the first drum support and the second drum flange disposed within and supported by the second drum support and wherein each notch is positioned directly above one of the first and second drum flanges.

13. The winch of claim 12 , wherein when a second main side rail of the two main side rails is rotated away from the first and second drum supports, each notch is positioned around, without contacting, one of the first and second drum flanges.

14. A winch, comprising:
a rotatable drum including a central rotational axis and supported within a housing of the winch, between a first drum support and a second drum support;
a tie structure directly coupled to and between only the first drum support and the second drum support, the tie structure positioned vertically above the rotatable drum and hinged at a first side of the tie structure that extends between the first and second drum supports and is adapted to rotate about a second rotational axis arranged in parallel with the central rotational axis, the tie structure including a notch at each end of the first side of the tie structure where the tie structure couples to the first and second drum supports.

15. The winch of claim 14 , wherein the drum includes a cylindrical portion disposed between a first drum flange and a second drum flange, the first drum flange disposed within and supported by the first drum support and the second drum flange disposed within and supported by the second drum support and wherein the notch at each of the first side of the tie structure is positioned directly, vertically above one of the first drum flange and the second drum flange.

16. A winch, comprising:
a housing including a first drum support and a second drum support;
a rotatable drum including a cylindrical portion positioned between first and second drum flanges, the first drum flange supported by the first drum support and the second drum flange supported by the second drum support; and
a rotatable tie structure positioned directly above and extending across the drum, between the first and second drum supports and from a first end to a second end of each of the first and second drum supports, the tie structure including notches that traverse a path adjacent to the first and second drum flanges when moving from a closed, first position to an open, second position.

17. The winch of claim 16 , wherein in the open, second position, the tie structure rotates about a first side of the tie structure that extends between the first end of the first drum support and the first end of the second drum support and a second side of the tie structure that extends between the second end of the first drum support and the second end of the second drum support, when the tie structure is in the closed, first position, is rotated upward and away from the rotatable drum.

18. The winch of claim 16 , wherein the tie structure includes two main side rails and two main cross rails, where the two main side rails are each coupled to and between the first and second drum supports and separated from one another across a width of the winch and wherein the t
