Abstract (en)
A lock has a runner (17) whose movement under turning of a correct key in the lock, is at right angles to that of the bolt (1). The runner (17) is coupled to the bolt (1) by a bell-crank (23) that engages via a peg (29) with a dogleg slot (31) of the bolt (1). A shoulder (37) of the runner (17) bears on the casing rear-wall (38) and lies immediately behind the bolt (1) for deadlocking it. Upward movement of the runner (17) under clockwise turning of the key is lost to the bolt (1) initially as the peg (29) traverses a first portion (32) of the slot (31), allowing the shoulder (37) to move clear before withdrawal of the bolt (1). Anti-clockwise turning of the key returns the runner (17), the peg (29) entering the lost-motion slot-portion (32) again after the bolt (1) is re-extended, to allow reintroduction of the shoulder (37) behind the bolt (1). The lower end of the slot (31) is enlarged to ensure that forcing of the bolt (1) is borne by the shoulder (37) alone.
