Abstract

An actuator assembly for use with a quick coupler. The actuator assembly includes a manual actuator assembly, a control rod coupled to the manual actuator assembly, and a remote actuator assembly coupled to the control rod. The manual actuator assembly is configured to be hand actuated from outside of the quick part coupler, and configured to move the latching assembly from a locked position to an unlocked position via the control rod. The remote actuator assembly is configured to be remotely actuated from outside of the quick coupler, and configured to move the latching assembly from the locked position to the unlocked position via the control rod.

First claim

What is claimed is:

1. An actuator assembly for use with a quick coupler, the actuator assembly comprising:
a manual actuator assembly including a lever, the manual actuator assembly configured to be hand actuated from outside of the quick coupler;
a control rod coupled to the manual actuator assembly;
a remote actuator assembly including an anchored portion and a movable portion, the remote actuator assembly coupled to the control rod, the remote actuator assembly configured to be remotely actuated from outside of the quick coupler; and
a latching assembly including a pivoter pivotably coupled to the control rod;
wherein the manual actuator assembly is configured to move the latching assembly from a locked position to an unlocked position via the control rod;
wherein the remote actuator assembly is configured to move the latching assembly from the locked position to the unlocked position via the control rod;
wherein the control rod includes a first end portion pivotably coupled to the manual actuator assembly, a second end portion pivotably coupled to the latching assembly, and a middle portion positioned therebetween;
wherein the anchored portion is anchored to the quick coupler and the movable portion is movable relative to the anchored portion and is configured to initiate back-and-forth movement of the middle portion at a connection point between the movable portion and the middle portion;
wherein the movable portion includes a first mover and a second mover, the first mover is positioned in a slot of the second mover, the second mover is fixed to the control rod so as to always move therewith; and
wherein the first and second movers slide relative to one another when the manual actuator assembly moves the latching assembly from the locked position to the unlocked position and vice-versa.

2. The actuator assembly of claim 1 , wherein the remote actuator assembly includes an electric actuator.

3. The actuator assembly of claim 1 , wherein the manual actuator assembly is configured to move the latching assembly from the locked position to the unlocked position without assistance from of the remote actuator assembly.

4. The actuator assembly of claim 1 , wherein the remote actuator assembly is configured to move the latching assembly from the locked position to the unlocked position without assistance of the manual actuator assembly.

5. The actuator assembly of claim 1 , wherein the remote actuator assembly is configured to move the latching assembly from the locked position to the unlocked position, such that movement of the manual actuator assembly is visible to an operator of the quick coupler, from a seat of the a work machine, as a result the remote actuator assembly moving the control rod and the control rod moving the manual actuator assembly.

6. The actuator assembly of claim 1 , wherein the control rod includes a first end portion coupled to the manual actuator assembly, a second end portion coupled to the latching assembly, and a middle portion positioned therebetween; and
wherein the remote actuator assembly is coupled to the middle portion, such that movement of the remote actuator assembly is transferred to the first and second end portions via the middle portion.

7. The actuator assembly of claim 6 , wherein when viewed from a rear of the quick coupler, the first and second end portions extend vertically inside of the quick coupler; and
wherein when viewed from the rear of the quick coupler and starting from the second end portion, the middle portion extends upwardly and laterally inwards inside of the quick coupler.

8. The actuator assembly of claim 6 , wherein when viewed from a side of the quick coupler, the first and second end portions extend vertically inside of the quick coupler; and
wherein when viewed from the side of the quick coupler and starting from the second end portion, the middle portion extends forwardly and upwardly inside of the quick coupler.

9. The actuator assembly of claim 1 , wherein the latching assembly includes a roller that is rotatably coupled to the pivoter; and
wherein the remote actuator assembly is configured to move the latching assembly from the locked position to the unlocked position via the control rod, such that the roller rolls relative to the pivoter and also rolls relative to and in contact with an implement.

10. The actuator assembly of claim 9 , wherein the pivoter pivots back-and-forth about a first axis and the roller rolls about a back-and-forth moving second axis positioned below the first axis.

11. The actuator assembly of claim 10 , wherein the pivoter is actuated at a back-and-forth moving third axis that is positioned in front of the first axis and in front of and above the moving second axis.

12. The actuator assembly of claim 1 , wherein the movable portion includes a first mover and a second mover;
wherein the second mover includes a first sidewall, a second sidewall, a third sidewall opposite of and facing the first sidewall, and a fourth sidewall opposite of and facing the second sidewall, the first sidewall has a vertical slot, the fourth sidewall has a matching vertical slot that is opposite of and aligned with the vertical slot; and
wherein the first mover is positioned in the vertical slots, such that the first mover slides relative to the vertical slots when the manual actuator assembly moves the latching assembly from the locked position to the unlocked position and vice-versa.

13. The actuator assembly of claim 1 , wherein the anchored portion includes an anchor aperture and an anchor pin, the anchor pin has a first end segment, a second end segment, and a middle segment positioned therebetween; and
wherein the first and second end segments are positioned in respective apertures of the quick coupler, and the middle segment is positioned inside of the quick coupler and in the anchor aperture.

14. The actuator assembly of claim 13 , wherein the remote actuator assembly includes a stabilizing cylinder;
wherein the middle segment includes a large diameter portion that is larger than a diameter of the anchor aperture and includes a small diameter portion that is smaller than the diameter of the anchor aperture;
wherein the large diameter portion and the stabilizing cylinder are positioned on opposite sides of the anchor aperture, so as to confine the anchor aperture; and
wherein the small diameter portion is positioned in the anchor aperture and in the stabilizing cylinder.

15. The actuator assembly of claim 1 , wherein when the first mover extends:
the first mover is configured to move the second mover via an end of the slot, and
the second mover is configured to move the manual actuator assembly via the control rod and to move the latching assembly from the locked position to the unlocked position via the control rod.

16. An actuator assembly for use with a quick coupler, the actuator assembly comprising:
a manual actuator assembly including a lever, the manual actuator assembly configured to be hand actuated from outside of the quick coupler;
a control rod coupled to the manual actuator assembly;
a remote actuator assembly including an anchored portion and a movable portion, the remote actuator assembly coupled to the control rod, the remote actuator assembly configured to be remotely actuated from outside of the quick coupler; and
a latching assembly including a pivoter pivotably coupled to the control rod;
wherein the manual actuator assembly is configured to move the latching assembly from a locked position to an unlocked position via the control rod;
wherein the remote actuator asse
