ABSTRACT:
An arrangement for controlling the closing sequence of two wings of windows, doors, and the like, especially smoke or fire protection doors, which are closable by means of a door-closing device each. The two wings are a moving wing to be opened first and a resting wing to be opened subsequently, so that projecting edges of the doors which face each other come into contact with each other in the correct sequence. A control device is actuated primarily by the slide rollers of the door-closing device of the resting wing when the resting wing is opened. With the use of a control lever and a sliding member displaced by the control lever toward the axis of rotation of the resting lever, a locking member is pivoted into the return end region of the guide roller of the door-closing device of the moving wing. This locking member locks the final closing movement of the moving wing until the resting wing has been closed. The sliding member is maintained with the aid of a locking device in a swung-out position until the resting wing has again been closed. The guide roller of the door-closing device of the resting wing releases the locking device.
