Abstract

The present invention relates to a closing sequence control for a double-leaf door, including a door having an inactive leaf and an active leaf, the door leaves thereof being movable by respectively one overhead door closer being mounted to the push-side of the door leaves at the inactive leaf and at the active leaf, wherein each overhead door closer includes a closer shaft, which is connected to the one end of a pivoting arm, which in turn, with its other end, is longitudinally movable guided in a frame-fixed guiding rail via a sliding member, and the sliding member, associated to the active leaf, is connected to a clamping rod which is supported in the guiding rail, which rod can be charged by a clamping element, which, when the inactive leaf is in the closing condition, is maintained in a releasing position by means of a trigger element, and, during an opening movement of the inactive leaf, it can be transferred into a blocking position by means of the trigger element. With the intention to configure such a closing sequence control in such a way that the door hinges of the door leaves can be disposed on the side facing away from the door closers, the guiding rail and the closing sequence control, wherein a reliable closing sequence control can be guaranteed without electrical, hydraulic or pneumatic control, according to the invention it is provided that the trigger element (8) is in operative connection with a double-armed lever (11), which can be charged by means of the closer shaft (5) of the overhead door closer (3) mounted to the inactive leaf (1) in such a way that the trigger element (8) transfers the blocking element (8) into its releasing position.
