Closing sequence control for door wings - has top rabbet wing with actuating element blocking its motion fitted in housing of other wing door closer assembly

摘要

The first (2) and second (3) wings are fitted with their own door closers (12,13). For the second wing (3) operated by the second door closer (13) a blocking device is provided which is operated by a Bowden cable in dependence of the closing position of the first wing (2). To eliminate problems hitherto experienced in connection with the routing of the controlling Bowden cable, the control operation of the Bowden cable involves a cam disc rigidly fixed on the door closers of the first wing (2) and both door closers are fitted on the blind frame, while the Bowden cable is routed on the door closer housings. Doors are closed in sequence, allowing edges ADVANTAGE -with top and bottom rabbets to fit together without clashing.
