Abstract
Embodiments provide a lock including an actuator that is movable between an unlocked position and a locked position, and a bolt that is movable between an extended bolt position and a retracted bolt position independent of the position of the actuator. In the extended bolt position, the bolt extends outside a body of the lock. A coupling element is arranged between the actuator and the bolt and is movable between an extended coupling position and a retracted coupling position in response to movement of the actuator between the locked position and the unlocked position. A first biasing element biases the coupling element toward the retracted coupling position, and a second biasing element couples the coupling element to the bolt and is structured to bias the bolt away from the coupling element and towards the extended bolt position.
