The invention relates to a locking/unlocking device for a double- wing door, the door comprising a semi-fixed wing (15) carrying a keeper (3) and a movable wing (14) carrying a lock (1), at least one bolt (1a, 1b) of which is capable of being engaged in the keeper (3). It is characterised in that it comprises an essentially vertical rod (13) which is mounted slidably on the semi-fixed wing (15) and of which one end is capable of engaging into a fixed hole (17) and the other end carries an actuating element (5), in that the keeper (3) is capable of sliding substantially horizontally on the semi-fixed wing (15) and has an essentially oblique slot (4) in which the said actuating element (5) is received, and in that there is a means (10; 11) for the vertical operation of the rod (13) in order selectively to engage the keeper (3) on the bolt or bolts (1a, 1b) of the lock or to disengage it and at the same time engage the said first end of the rod (13) into the hole (17) and disengage it from this. <IMAGE> |
