Abstract

A carrier for an implement that can be operably coupled to a power machine. In one example, an implement carrier can be mountable to a power machine for securing an implement for use with the power machine. The implement carrier can include an implement carrier frame, a locking feature for securing an implement, and a coupler block that is pivotally mounted to the implement carrier frame for engaging couplers on the implement.

First claim

What is claimed is:

1. An implement carrier configured to be mounted to a power machine, the implement carrier being configured to receive and secure an implement for use with the power machine, comprising:
an implement carrier frame;
a locking feature for securing the implement to the implement carrier frame; and
a coupler block having a first plurality of couplers mounted therein for engagement with a second plurality of couplers on the implement to provide a power source for the implement,
wherein the coupler block is pivotally mounted to the implement carrier frame such that the coupler block freely rotates around an axis.

2. The implement carrier of claim 1 , wherein the coupler block freely rotates around the axis in either of two directions without restraint.

3. The implement carrier of claim 1 , wherein the frame includes an engagement feature for engaging the implement such that when the implement is being received, the implement is intended to be engaged by the engagement feature and subsequently secured by the locking feature.

4. The implement carrier of claim 1 wherein the coupler block has a housing and a moveable member located within the housing, the first plurality of couplers being fixed to the moveable member such that movement of the moveable member causes the first plurality of couplers to move relative to the housing.

5. The implement carrier of claim 1 , wherein at least one of the first plurality of couplers is configured to provide pressurized hydraulic fluid to the implement after the implement has been received and secured.

6. The implement carrier of claim 1 , wherein the implement carrier frame has a front side and an opposing rear side and wherein the coupler block is pivotally mounted to the rear side of the implement carrier frame and the first plurality of couplers is accessible from the front side of the implement carrier frame.

7. The implement carrier of claim 6 , wherein the implement carrier frame has an aperture through which access to the first plurality of couplers is provided.

8. The implement carrier of claim 1 , wherein the implement carrier frame has a generally flat surface against which the implement is positionable and wherein the coupler block has a front face on which the first plurality of couplers is accessible, the front face being configured to be positioned generally parallel with the flat surface of the implement frame when the implement is locked to the implement carrier frame.

9. The implement carrier of claim 1 , wherein the coupler block pivots freely until locked from an actuator.

10. The implement carrier of claim 1 , further comprising a plate with a planar surface, wherein the pivotal mounting of the coupler block is behind the plate with the first plurality of couplers accessible through the plate.

11. The implement carrier of claim 10 wherein the implement carrier frame includes an alignment feature that includes an aperture for alignment of the implement with the implement carrier, and wherein the alignment feature is on the plate.

12. A power machine, comprising:
a frame;
a power source supported by the frame;
a lift arm pivotally mounted to the frame; and
an implement carrier pivotally mounted to the lift arm, the implement carrier being configured to receive and secure an implement for use with the power machine, the implement carrier including a locking mechanism for securing the implement and a plurality of couplers configured to be engaged with the implement to provide a power signal from the power source to the implement;
wherein the implement carrier is further configured so that receiving and securing the implement also causes the plurality of couplers on the implement carrier to be aligned and engaged with the implement; and
wherein the plurality of couplers freely rotates around an axis.

13. The power machine of claim 12 , wherein the implement carrier comprises:
an implement carrier frame; and
a coupler assembly that houses the plurality of couplers, the coupler assembly being pivotally mounted to the implement carrier frame such that the coupler assembly is configured to rotate to align the plurality of couplers with corresponding couplers on the implement carrier.

14. An implement in combination with the power machine of claim 13 , the implement comprising:
an implement carrier interface having a locking feature engaged by the locking mechanism and a plurality of implement couplers mounted thereon in engagement with the plurality of couplers on the implement carrier.

15. The power machine of claim 12 , wherein at least one of the plurality of couplers is a hydraulic coupler.

16. The power machine of claim 13 , wherein the coupler assembly has a moveable element configured to move the plurality of couplers within the coupler assembly.

17. The implement carrier of claim 12 , wherein the first plurality couplers freely rotate around the axis in either of two directions without restraint.

18. The combination of claim 14 , wherein the weight of the implement urges the plurality of implement couplers on the implement carrier interface into engagement with the plurality of couplers on the implement carrier.

19. A method of interfacing an implement with a power machine, comprising:
providing an implement carrier on the power machine capable of engaging and securing the implement to the power machine, the implement carrier having:
a frame with a generally flat surface for engaging the implement;
a coupler assembly housing a first plurality of couplers that provide a power source to the implement, the coupler assembly being positioned on a back side of the frame and the first plurality of couplers being accessible from a front side of the frame,
wherein the coupler assembly is pivotally mounted to the frame such that the coupler assembly freely rotates around an axis; and
a locking mechanism for securing the implement to the implement carrier;

aligning the implement carrier with and engaging the implement;
aligning the coupler assembly with a second plurality of couplers on the implement; and
actuating the locking mechanism to secure the implement to the implement carrier.

20. The method of claim 19 , wherein the coupler assembly is pivotally mounted to the frame of the implement carrier and aligning the coupler assembly with the second plurality of couplers on the implement includes providing a first locating member on the implement configured to engage a second locating member on the coupler assembly.

21. The method of claim 20 , wherein engaging the second locating member on the coupler assembly causes the coupler assembly to rotate with respect to the frame.

22. The method of claim 19 , wherein aligning the implement carrier with and engaging the implement includes moving an engagement feature on the implement carrier into engagement with an engagement feature on the implement and causing the implement to rotate into an aligned position with the implement carrier.

23. The method of claim 19 and further comprising:
moving the first plurality of couplers on the coupler assembly to cause the first plurality of couplers to move closer to the second plurality of couplers on the implement.

24. The method of claim 19 and further comprising:
lifting the implement to allow the weight of the implement to urge the second plurality of couplers on the implement into engagement with the first plurality of couplers on the coupler assembly.
