Abstract

A manual marine winch includes a safety loading handle and integrated locking dog release. The winch includes a handle for selectively tensioning and selectively releasing tension on winch; a tensioning ratchet gear coupled to the drum assembly for selectively tensioning the winch; a tensioning ratchet pawl mounted on the handle and selectively engaged with the tensioning ratchet gear for tensioning of the winch; at least one tension holding ratchet gear coupled to the drum assembly for holding tension on the winch; at least one locking dog pawl selectively engaged with each tension holding ratchet gear to hold tension on the winch; and a knockout member carried on the handle and configured to selectively disengage the locking dog pawls from the tension holding ratchet gears to allow for release of tension on the winch.

Claims

1. A manual marine winch comprising:

a winch housing;

a rotating drum assembly supported on the winch housing; and

a manually actuated control assembly engaged with the drum assembly for spooling and un-spooling a winch line on the drum assembly, wherein the manually actuated control includes

i) a handle for selectively tensioning the drum assembly and moveable between a position engaged with the drum assembly through the control assembly for tensioning of the winch line on the drum assembly and at least one stowed position wherein the handle is not engaged with the drum assembly for tensioning the drum assembly;

ii) a tension holding mechanism on the winch comprising at least one tension holding ratchet gear coupled to the drum assembly and at least one locking dog pawl selectively engaged with said at least one tension holding ratchet gear to hold tension on the winch line on the drum assembly, and

iii) a knockout member carried on the handle and configured to selectively disengage each of said at least one locking dog pawl from the tension ratchet gears to allow for release of tension on the winch, wherein the knockout member is positioned on the handle to disengage each of said at least one locking dog pawl from the tension holding ratchet gears only when the handle is disengaged from the drum assembly.

2. The marine winch of claim 1 wherein the handle is pivoted between respective positions.

3. The marine winch of claim 2 wherein the handle includes a tensioning ratchet pawl mounted on a pivot on the handle and selectively engaged with a tensioning ratchet gear that is coupled to the drum assembly.

4. The marine winch of claim 3 wherein the ratchet pawl is configured to engage the tensioning ratchet gear when tensioning the winch line on the drum assembly with the handle.

5. The marine winch of claim 4 wherein the tensioning ratchet pawl is configured to pivot out of engagement with the tensioning ratchet gear as the handle is moved to a first stored position.

6. The marine winch of claim 5 wherein the knockout member carried on the handle is configured to selectively disengage each of said at least one locking dog pawl from the tension holding ratchet gears after the handle is moved past the first stored position away from the engaged position in which the handle may selectively tension the winch line on the drum assembly.

7. The marine winch of claim 6 further including at least two of the locking dog pawls selectively engaged with at least two of the tension holding ratchet gears.

8. The marine winch of claim 7 wherein the tension holding ratchet gears engaged by the locking dog pawls are circumferentially offset from each other.

9. The marine winch of claim 7 wherein the locking dog pawls are on opposed sides of the handle.

10. The marine winch of claim 9 wherein the tensioning ratchet gear engaged by the tensioning ratchet pawl for selective tensioning is distinct from the tension holding ratchet gears engaged by the locking dog pawls.

11. A manual marine winch comprising:

a winch housing;

a rotating drum assembly supported on the winch housing; and

a handle for selectively tensioning a winch line on the drum assembly and selectively releasing tension on the winch line on the drum assembly;

a tensioning ratchet gear coupled to the drum assembly and configured for selectively tensioning the winch line on the drum assembly;

a tensioning ratchet pawl mounted on the handle and selectively engaged with the tensioning ratchet gear for tensioning of the winch line on the drum assembly;

at least one tension holding ratchet gear coupled to the drum assembly for holding tension on the winch line on the drum assembly;

at least one locking dog pawl selectively engaged with said at least one tension holding ratchet gear to hold tension on the winch line on the drum assembly; and

a knockout member carried on the handle and configured to selectively disengage each of said at least one locking dog pawl from the tension holding ratchet gears to allow for release of tension on the winch.

12. The marine winch of claim 11 wherein the handle is pivoted between respective positions.

13. The marine winch of claim 12 wherein the tensioning ratchet pawl is mounted on a pivot on the handle.

14. The marine winch of claim 13 wherein the tensioning ratchet pawl is configured to engage the tensioning ratchet gear when tensioning the winch line on the drum assembly with the handle.

15. The marine winch of claim 14 wherein the tensioning ratchet pawl is configured to pivot out of engagement with the associated ratchet gear as the handle is moved to a first stored position.

16. The marine winch of claim 15 wherein the knockout member carried on the handle is configured to selectively disengage each of said at least one locking dog pawl from the ratchet gears after the handle is moved past the first stored position away from the engaged position in which the handle may selectively tension the winch line on the drum assembly.

17. The marine winch of claim 16 further including at least two of the locking dog pawls which are coaxially mounted and selectively engaged with at least two of the ratchet gears which are coaxially mounted.

18. The marine winch of claim 17 wherein the ratchet gears engaged by the locking dog pawls are circumferentially offset from each other.

19. The marine winch of claim 18 wherein the locking dog pawls are on opposed sides of the handle.

20. The marine winch of claim 19 wherein the ratchet gear engaged by the tensioning ratchet pawl for selective tensioning is distinct from the ratchet gears engaged by the locking dog pawls and is coaxially mounted there with.
