<p>PCT No. PCT/CH96/00183 Sec. 371 Date Sep. 15, 1997 Sec. 102(e) Date Sep. 15, 1997 PCT Filed May 13, 1996 PCT Pub. No. WO97/11246 PCT Pub. Date Mar. 27, 1997The invention concerns a lock for doors or operationally similar structures, the lock mechanism being manually actuated with the aid of pneumatic means, without the need for external energy. Means for manually producing overpressure are rigidly connected to a door. Further means are provided for converting the overpressure into a mechanical movement of parts of the closure mechanism, such that there is no longer any force-locking connection between the door and a counterpart in the door frame whereby the door can be opened.</p> |
