A closure sequence controller for a pair of first and second door leaves pivotable with respect to a door frame includes an elongate guide rail for mounting to the door frame, a first elongate sliding bar positioned in the guide rail and functionally connected to the first door leaf in a manner such that the first sliding bar moves in response to pivotal movement of the first door leaf relative to the door frame, and a sequence control unit installed in the guide rail and functionally connected to the first sliding bar. The sequence control unit includes a lock body structure defining a chamber through which the first sliding bar extends and having a guiding surface that is inclined with respect to the first sliding bar. A blocking member is located in the chamber and movable therein longitudinally of the first sliding bar. A biasing element urges the blocking member in a direction towards a position in which the blocking member is clamped tightly against the first sliding bar and prevents closing of the first door leaf.

Closure sequence control arrangement for double doors

A closure sequence controller for a double door arrangement in which the double door arrangement is provided with a first door closer and a first pull arm for closing a first door leaf and with a second door closer and a second pull arm for closing a second door leaf. A guide rail guides the distal ends of the pull arms relative to the door closers. The closure sequence controller includes a connection piece for transmitting a pulling force from the distal end of the first pull arm to the closure sequence controller. The closure sequence controller prevents movement of the distal end of the second pull arm in the guide rail past the closure sequence controller until the distal end of the first pull arm has exerted the pulling force on the closure sequence controller through the connection piece.
