发明名称 Mortise lockset with internal clutch having override feature
摘要 <p>A lock mechanism has a housing and a latch extending from the housing. The latch has an extended position and a retracted position. The mechanism includes apparatus for biasing the latch to the extended position, apparatus for defining a locked mode and an unlocked mode, and apparatus including a clutch for transferring an operator input motion to move the latch to the retracted position in the unlocked mode. The clutch includes a cam surface and a cam follower. A spring biases the cam follower toward the cam surface and a second override spring which biases the cam follower to compensate for any off-center relationship due to wear, excessive force and/or assembly misalignment and to prevent jamming.</p>
