Abstract

An assist device for lifting and facilitating the coupling of an implement's driveline to a power take-off on a vehicle is disclosed. The assist device is configured with a handle enabling a user to rotate the device from a storage position to an upright position where the device engages the driveline and hits it into a position suitable for coupling the driveline to the power take-off. The assist device is equipped with a roller to allow the driveline to slide along its longitudinal axis to facilitate coupling. The assist device may be equipped with one or more springs to further accept at least some of the weight of the driveline and enable easier maneuvering of the driveline during the coupling process.

Claims (32)

1. An assist device for an implement, comprising: a pivot attached to

a frame;

a cradle attached to the pivot, the cradle configured to receive a driveline of the implement, the driveline including a longitudinal axis, the cradle comprised of a first side and a second side, each of the first side and second side attached to the pivot, where the driveline is disposed between the first side and second side when the assist device is engaged with the driveline; and

a handle attached to one of the first side or second side, and extending past the cradle and the other of the first side or second side, distally from the pivot, configured to allow a user to rotate the cradle about the pivot,

wherein the cradle is disposed apart from the pivot so that rotating the cradle about the pivot causes the cradle to change height relative to the frame, enabling the cradle to selectively engage with the driveline and raise the driveline into a position for coupling the driveline to a power take-off.

2. The assist device of claim 1 , wherein the cradle is configured to allow the driveline to extend and/or contract along the driveline's longitudinal axis.

3. The assist device of claim 2 , wherein the cradle further comprises a roller.

4. The assist device of claim 3 , wherein the cradle can rotate about the pivot between a storage position and a position where the roller is engaged with the driveline and accepts at least part of the weight of the driveline.

5. The assist device of claim 3 , wherein the roller is attached to the cradle using at least one spring, the at least one spring being configured to accept at least part of the weight of the driveline during coupling of the driveline to the power take-off.

6. The assist device of claim 2 , wherein the cradle is further configured to allow the driveline to move perpendicular to the driveline's longitudinal axis.

7. The assist device of claim 1 , wherein the frame is part of an implement frame.

8. The assist device of claim 1 , wherein the frame is part of a tractor frame.

9. The assist device of claim 1 , wherein the cradle can be selectively detached from the pivot.

10. An implement, comprising:

a frame;

an implement with a driveline, the driveline having a longitudinal axis; and an assist device secured to the frame, the assist device further comprising:

a cradle sized to receive the driveline, the cradle comprised of a first side and a second side, where the driveline is disposed between the first side and second side when the assist device is engaged with the driveline; and

a handle attached to one of the first side or second side and extending past the cradle and the other of the first side or second side, the cradle configured to allow a user to rotate the cradle with respect to the frame and in line with the longitudinal axis;

wherein rotating the cradle causes the cradle to change height relative to the frame, and cause the cradle to selectively engage with the driveline and raise the driveline into a position that facilitates coupling the driveline to a power take-off.

11. The implement of claim 10 , wherein the cradle is configured to allow the driveline to extend and/or contract along the driveline's longitudinal axis.

12. The implement of claim 11 , wherein the cradle further comprises a roller.

13. The implement of claim 12 , wherein the cradle can rotate between a storage position and a position where the roller is engaged with the driveline and accepts at least part of the weight of the driveline.

14. The implement of claim 12 , wherein the roller is attached to the cradle using at least one spring, the at least one spring being configured to accept at least part of the weight of the driveline during coupling of the driveline to the power take-off.

15. The implement of claim 10 , wherein the cradle is further configured to allow the driveline to move perpendicular to the driveline's longitudinal axis.

16. The implement of claim 10 , wherein the power take-off is part of a tractor configured to tow the implement.

17. A method for coupling a driveline of an implement with a power take-off, comprising:

rotating a cradle about a pivot, the cradle comprised of a first side and a second side, each of the first side and second side attached to the pivot, where the driveline is disposed between the first side and second side when the cradle is engaged with the driveline;

using a handle attached to one of the first side or second side, and extending past the cradle and the other of the first side or second side, distally from the pivot, so as to cause the cradle to engage the driveline; and

coupling the driveline with the power take-off by further rotating the cradle about the pivot, so as to cause the driveline to raise vertically away from a frame of the implement into an engagement position.

18. The method of claim 17 , wherein the cradle is configured to allow the driveline to extend and/or contract along the driveline's longitudinal axis, and coupling the driveline with the power take-off further comprises extending and/or contracting the driveline along the driveline's longitudinal axis, when the driveline is in the engagement position, until the driveline engages the power take-off.

19. The method of claim 18 , wherein the cradle is further configured to allow the driveline to move perpendicularly with respect to its longitudinal axis, and coupling the driveline with the power take-off further comprises moving the driveline perpendicularly when the driveline is in the engagement position.

20. The method of claim 19 , wherein cradle engages the driveline using a roller attached to the cradle using at least one spring, the at least one spring being configured to accept at least part of the weight of the driveline during coupling of the driveline to the power take-off.
