verriegelungsvorrichtung for zweiflügelige doors, in particular fire and rauchschutztüren

摘要

A locking device (2) for double-wing doors (1) has a fixing device (3) for locking one of the two door wings (1a) relative to the door jamb (4) or the like and a pusher-actuable latch lock (5) for the interlocking of the two door wings (1a,1b). To reduce the outlay in terms of construction and to simplify the conditions for construction and installation, the fixing device (3) and the latch lock (5) are arranged on the same door wing (1a), the fixing device (3) consisting of an edge catch (6) which is located in the region of the upper door-wing edge and which is connected operatively to the latch lock (5) via a tension member (7) and, as a result of the actuation of the latch-lock pusher (5b), can be pulled back counter to spring force out of the closing position into an open position simultaneously with the latch (5a) of the latch lock.
