Abstract:
1. A lockset, comprising: a first actuating mechanism configured to receive an input from a first handle so that when the first handle is actuated, the first actuating mechanism urges a first retractor arm to rotate; a second actuating mechanism configured to receive an input from a second handle so that when the second handle is actuated, the second actuating mechanism urges a second retractor arm to rotate; the first and second retractor arms being disposed on opposite sides of a lockset axis; a retractor constrained so as to be movable in a direction transverse to the lockset axis, the retractor having first and second ends; the first retractor arm extending through the first end of the retractor so that a distal end of the first retractor arm is within the retractor, and when the first retractor arm rotates, the first retractor arm distal end engages a contact surface of the retractor and urges the retractor to move in the direction transverse to the lockset axis; the second retractor arm extending through the second end of the retractor so that a distal end of the second retractor arm is within the retractor, and when the second retractor arm rotates, the second retractor arm distal end engages the contact surface of the retractor and urges the retractor to move in the direction transverse to the lockset axis; and an elongate locking member movable between a locked position and an unlocked position, a control arm extending from and moving with the locking member, the control arm having a lock portion configured so that when the locking member is in the locked position the lock portion blocks the second retractor arm from rotating sufficient to engage the retractor contact surface; wherein the first retractor arm is not blocked from rotation when the locking member is in the locked position; and wherein the control arm is configured so that when the retractor is moved by the first retractor arm when the locking member is in the locked position, the moving retractor engages a control surface that is attached to the locking member so as to urge the locking member from the locked position toward the unlocked position.
