Abstract
A locking apparatus for a sliding closure slidable within a frame is disclosed. The locking apparatus comprises at least one locking tang movable transversely to the closure plane, between a locking position and a release position wherein, when in the locking position the locking tang extends laterally, in a direction transverse to the closure lane, beyond the closure to be received within a corresponding locking recess in the frame, such that the locking tangs resist opening of the closure, and when in the release position the locking tang is withdrawn within the dimensions of the frame, such that the closure may be opened or closed. The locking mechanism may also comprise a sensor configured to detect when at least one of the locking tangs are in the locked or released position, and, optionally to trigger an alarm if the locking tang is disengaged.
