<p>A closure sequence control arrangement for a door comprising first and second door leaves (1,2) hinged to opposite sides of a door frame (3), the door having a first closer unit (4) and a first pivot arm (5) for closing the first door leaf (1) and a second door closer unit (6) and a second pivot arm (7) for closing the second door leaf (2). The arrangement includes guide rail means (8) or the like supported on the door frame (3) for guiding ends (5a,7a) of the pivot arms (5,7) remote from the door closers, and closure sequence control means (9) cooperating with the guide rail means (8). The closure sequence control means (9) include a connection piece (10,11,12) arranged in the guide rail means (8) between the ends (5a,7a) of the pivot arms and movable against the force of a spring (15), a support element (13) stationarily supported to the guide rail means (8), and a movable blocking member (14). The closure sequence control means (9) are arranged in cooperation with the opposite ends (5a,7a) of the pivot arms at the end phase of the closing movement of the door leaves so that the blocking member (14) prevents movement of the end (7a) of the second pivot arm (7) in the guide rail means (8) until the end (5a) of the first pivot arm (5) affects the blocking member (14) through the connection piece (10,11,12) so that the blocking member (14) allows closing of the second door leaf (2). The blocking member (14) is received in a guide aperture (13b) in the support element (13) so that, in its blocking position, the blocking member (14) projects partly from the guide aperture (13b) into the path of movement of the end (7a) of the second pivot arm (7). <IMAGE></p> |
