Couplers

摘要

A coupler for coupling implements having a first connecting pin and a second connecting pin, to a vehicle, for example, to the arm of an excavator. The coupler has a body component that is connectable to the vehicle, and which includes a forward recess for receiving the first connecting pin. The coupler also includes a movable component which is supported by the body component and which has an aft jaw or recess for receiving the second connecting pin and is movable through a range of travel relative to the body component. The movable component includes a rear locking member which is movable between an extended position in which the rear locking member can prevent the second connecting pin from exiting the aft recess and a retracted position in which the rear locking member can allow the second connecting pin to exit the aft recess.

主权项

1. A coupler assembly for coupling implements having a first connecting pin and a second connecting pin, to a vehicle, the coupler assembly comprising;
a body component that is connectable to the vehicle, the body component comprising a forward recess for receiving the first connecting pin, a movable component that is supported by the body component and which is movable through a range of travel relative to the body component, the movable component comprising or forming a part of an aft recess for receiving the second connecting pin, an actuator configured to selectively move the movable component relative to the body component, and an aft locking member configured to move between a first position in which the aft locking member prevents movement of the second connecting pin out of the aft recess and a second position in which the aft locking member allows movement of the second connecting pin out of the aft recess; and the actuator is also configured to move the aft locking member to and from the said first and second positions of the aft locking member.
