ABSTRACT:
A lock mechanism comprises a housing and a rotor mounted within a bore of the housing having a skirt, the rotor and skirt being rotatable by a knob. A lock opening and closing lever is rotatable between locking and unlocking positions and a rod is drivably connected to the lock opening and closing lever and serves for connection to a latching device.
A securing and release lever drivably connected with the rotor through a drive tang and a slot permitting lost motion is movable by an actuator independently of the rotor.
A slider is movable in a groove in the opening and closing lever by the securing and release lever between a first position on release to effect a driving connection between the rotor and the lock opening and closing lever by engagement of the slider with an aperture in the skirt and a second position on securing to disconnect the drive between the rotor and the lock opening and closing lever by withdrawal of the slider from the aperture in the skirt and to permit the rotor and knob to rotate freely.
