Abstract
1369320 Time-controlled locks OTTO SELLIN GmbH 19 Oct 1972 [20 Oct 1971] 48111/ 72 Heading E2A A time-controlled lock 1 comprises at least one mechanical or electric clockwork mechanism 3 for withdrawing a blocking member 8 or for unblocking the path of a locking member 10 at a preselectable time and separate therefrom an optical and/or acoustic indicating device associated with the clockwork mechanism(s) or directly or indirectly driven thereby for disclosing the presence of and the blocking of the lock and for indicating at least the final part of the time remaining to the unblocking of the lock. The indicating device may comprise a ammeter which is in circuit with a variable potentiometer, the potentiometer having a setting pinion which is driven by a rack of the blocking member 8 (Fig. 4, not shown). Alternatively the blocking member 8 may be provided with a contact which cooperates with a series of fixed contacts each of which is in the circuit of a signalling lamp (Figs. 5 to 8, not shown). The contact of the member 8 may be of sufficient area to bridge two contacts as it moves from one contact to the next. The contact of the member may be a rotary multi-position contact. A gear wheel on the output shaft of at least one of the clockwork mechanisms may be connected to a potentiometer. The blocking member 8 may be moved more quickly during the final part of the unblocking movement then during the remainder thereof, the scales of the visual indicator being correspondingly "stretched". The two stage movement is achieved, as shown, by providing a shift bar 7 actuated by a pin 5 of a clockwork mechanism 3. The shift bar 7 is mounted on swing arms 25, 26 and a transmission arm 28 is connected to swing arm 26 at its pivot 27. The arm 28 has a slot 30 in which works a pin 31 of a pivoted lever arm 29 which co-operates with the blocking member 8 to withdraw the same. The slot 30 is provided with a "kink" 33 which provides for the increased rate of withdrawal of the blocking member 8.
