Abstract
A coupler for a construction attachment includes a frame including: (i) an upper portion adapted to be secured to an associated excavator; and, (ii) a lower portion adapted to be releasably coupled to a construction attachment. The lower portion of the frame includes a first hook and a second hook. A lock member is movably connected relative to the frame and is movable between an extended position and a retracted position. The first and second hooks include respective open mouths and the lock member obstructs the open mouth of the second hook when the lock member is in the extended position. An actuator is operably connected to the lock member and is adapted to move the lock member between its extended and retracted positions. The lock member slides and pivots sequentially relative to the frame when moved by the actuator from the extended position to the retracted position, and the lock member pivots and slides sequentially relative to the frame when moved by the actuator from the retracted position to the extended position.
