<p>A closure sequence control arrangement for turnable double doors, in which the double doors are provided with a first door closer unit (4) and with a first pull arm (5) for closing a first door leaf (1) and with a second door closer unit (6) and with a second pull arm (7) for closing a second door leaf (2), with a guide rail (8) or the like for guiding the distal end (5a,7a) of the pull arms (5,7) with regard to the door closers, and with closure sequence control means (9) which include connection means (10-12) for transferring the effect of the distal end (5a) of the first pull arm (5) to the closure sequence control means (9). The closure sequence control means (9) are arranged to prevent movement of the end (7a) of the second pull arm (7) in the guide rail (8) until the end (5a) of the first pull arm (5) has affected the closure sequence control means (9) through the connection piece (10-12) so that they allow closing of the second door leaf (2). The distal end (5a) of the first pull arm (5) and the connection means (10-12) include members for transmitting pulling force therebetween, whereby the effect is accomplished by pulling force which the distal end (5a) of the first pull arm (5) transmits by means of the connection means (10-12) into the closure sequence control means (9). <IMAGE></p> |
