Abstract

Provided is a pick-up hitch assembly for connection to a vehicle. The pick-up hitch assembly includes a swing frame having a first end configured to be coupled to the vehicle and a second end, a slide frame movable relative to the swing frame between a retracted position and an extended position, and an electrically powered actuator assembly configured to be coupled to the vehicle and being coupled to the swing frame at the second end of the swing frame. The actuator assembly is configured to move the swing frame between a raised position and a lowered position independent of movement of the slide frame and of a three-point hitch.

First claim

What is claimed is:

1. A pick-up hitch assembly for connection to a vehicle, the pick-up hitch assembly comprising:
a swing frame having a first end configured to be coupled to the vehicle and a second end;
a slide frame movable relative to the swing frame between a retracted position and an extended position; and
an electrically powered actuator assembly configured to be coupled to the vehicle and being coupled to the swing frame at the second end of the swing frame, the actuator assembly configured to move the swing frame between a raised position and a lowered position independent of movement of the slide frame, the actuator assembly including first and second electric motors.

2. The pick-up hitch assembly according to claim 1 , wherein the electrically powered actuator assembly includes first and second rail assemblies, each rail assembly including a rail configured to be coupled to the vehicle, a lead screw disposed in the rail and configured to be rotated by a respective one of the first and second electric motors, a block movable vertically by rotation of the lead screw, and a link pivotally coupled to the block and the second end of swing frame to effect raising and lowering of the swing frame.

3. The pick-up hitch assembly according to claim 2 , wherein each rail includes a chamber extending along a length of the rail in which the lead screw and a first portion of the block are disposed, and a slot extending along the length of the rail into the chamber through which a second portion of the block extends to pivotally couple to the link.

4. The pick-up hitch assembly according to claim 3 , further including a pin coupled to each of the second portions of the blocks, wherein each link includes an opening through which one of the pins extends to pivotally couple the link to the respective second portion of the block.

5. The pick-up hitch assembly according to claim 2 , further including pins coupled to the swing frame at opposite sides of the second end, wherein each link includes an opening through which one of the pins extends to pivotally couple the link to the second end of the swing frame.

6. The pick-up hitch assembly according to claim 1 , further including a cylinder having a first end coupled to the swing frame and a second end coupled to the slide frame to movably couple the slide frame to the swing frame and move the slide frame between the retracted position and the extended position.

7. The pick-up hitch assembly according to claim 1 , wherein the slide frame has a first end configured to be proximate the first end of the swing frame in the retracted position and a second end, and wherein the slide frame is configured to be locked at the first end in the retracted position.

8. The pick-up hitch assembly according to claim 7 , further including a pair of hooks pivotally coupled to the swing frame and movable by an actuator between a locked position where the hooks engage the slide frame at the first end to prevent movement of the slide frame from the retracted position, and an unlocked position where the hooks disengage the slide frame to allow movement of the slide frame to the extended position.

9. The pick-up hitch assembly according to claim 8 , further comprising the actuator, wherein the actuator is a linear actuator coupled to the swing frame and includes a movable rod coupled to a pin that is coupled to each of the hooks, wherein when the linear actuator is in a retracted position the hooks are in the locked position, and when the linear actuator is in an extended position the hooks are in the unlocked position.

10. The pick-up hitch assembly according to claim 1 , further comprising an implement coupled to the slide frame to move with the slide frame between the retracted position and the extended position.

11. The pick-up hitch assembly according to claim 1 , further including a pair of front supports pivotally coupled to the first end of the swing frame and configured to be coupled to the vehicle such that the swing frame can pivot relative to the vehicle between the raised position and the lowered position.

12. The pick-up hitch assembly according to claim 1 , further comprising wear plates disposed in the swing frame and secured to the swing frame above and below the slide frame for the slide frame to move along.

13. A vehicle comprising:
a frame having a rear vehicle housing; and
a pick-up hitch assembly attached to the rear vehicle housing, the pick-up hitch assembly including:
a swing frame having a first end pivotally coupled to the vehicle and a second end;
a cylinder having a first end coupled to the swing frame and a second end;
a slide frame coupled to the second end of the cylinder and movable relative to the swing frame between a retracted position and an extended position; and
an electrically powered actuator assembly configured to be coupled to the vehicle and being coupled to the swing frame at the second end of the swing frame, the actuator assembly configured to move the swing frame between a raised position and a lowered position independent of a three-point hitch assembly,

wherein a horizontal load applied by an implement passes through the pick-up hitch assembly to the rear vehicle housing and a vertical load applied by the implement passes through the pick-up hitch assembly to a pick-up hitch fix frame.

14. The vehicle according to claim 13 , wherein the electrically powered actuator assembly includes first and second rail assemblies, each rail assembly including a rail configured to be coupled to the vehicle, an electric motor, a lead screw disposed in the rail and configured to be rotated by the electric motor, a block movable vertically by rotation of the lead screw, and a link pivotally coupled to the block and the second end of swing frame to effect raising and lowering of the swing frame.

15. The vehicle according to claim 14 , wherein each rail includes a chamber extending along a length of the rail in which the lead screw and a first portion of the block are disposed, and a slot extending along the length of the rail into the chamber through which a second portion of the block extends to pivotally couple to the link.

16. A pick-up hitch assembly for connection to a vehicle, the pick-up hitch assembly comprising:
a swing frame having a first end configured to be coupled to the vehicle and a second end;
a slide frame coupled to the swing frame and movable relative to the swing frame between a retracted position and an extended position; and
an actuator assembly configured to be coupled to the vehicle and being coupled to the swing frame at the second end, the actuator assembly including first and second rail assemblies each having:
a rail with a chamber extending along a length of the rail and a slot extending along the length of the rail into the chamber,
an electric motor,
a lead screw disposed in the chamber and configured to be rotated by the electric motor,
a block movable vertically by rotation of the lead screw, and
a link pivotally coupled to the block and the second end of swing frame to effect movement of the swing frame between a raised position and a lowered position.

17. The pick-up hitch assembly according to claim 16 , further including a pair of hooks pivotally coupled to the swing frame and movable by a linear actuator between a locked position where the hooks engage the slide frame at a first end of the slide frame to prevent movement of the slide frame from the retracted position, and an unlocked position where the hooks disengage the slide frame to allow movement of the slide frame to the ext
