Patent ID: 8403590

Claim:
A coupler for an excavator, the coupler comprising a body having first and second recesses for receiving first and second pins, respectively, of an attachment; a latching member movable into and out of a latching state in which it at least partially closes the second pin-receiving recess; and a blocking member movable into and out of a blocking state in which a portion of the blocking member at least partially or fully closes the first recess, an actuator for moving the latching member into and out of its latching state, the actuator acting indirectly upon the blocking member to move the blocking member into and out of its blocking state as the latching member is moved into and out of its latching state, wherein the actuator acts upon the blocking member via a resiliently deformable member acting between the actuator and the blocking member, wherein the actuator comprises a linear actuator, having a first end directly coupled to the body of the coupler and a second end directly coupled to the latching member, wherein the latching member and/or the blocking member comprises a hook pivotally coupled to the body of the coupler and wherein the blocking member is pivotally coupled to the body of the coupler at a location between the first and second recesses.
