发明名称 SERRATURA DI SICUREZZA A TEMPO A DOPPIO MOVIMENTO
摘要 <p>A two movement time lock for bank vault doors and the like including a lock case for enclosing the timer units and a cover having transparent portions through which the dials of the timer units can be viewed. A pivoted integral locking lever of generally inverted distorted "T" shaped configuration has a pair of oppositely extending foot formations to be engaged and moved by trip formations of the timer units and a spring biased lever is interlinked with the locking lever above the pivot for normally positioning the locking lever at a cocked position when timer unit dials are displaced from the zero position. A pivoted snubber-bar blocking lever in the lock case is normally spring biased to a release position freeing a snubber bar to move to an unlocking position and a spring biased plunger has a first plunger position for forcing the blocking lever to snubber-bar blocking position and has a portion engagable by the locking lever for releasably restraining the plunger in such position when the locking lever is in cocked position.</p>
