Abstract

A door closing arrangement includes a first door closer for closing a first door leaf, the first door closer being positioned on the opposite side of the first door leaf from the its hinge, and a second door closer for closing a second door leaf. The distal end of the pull arm of the first door closer moves along a guide member in a direction towards the second edge of the door frame during movement of the first door leaf from a fully open position to a partially closed position and moves along the guide member in a direction towards the first edge of the door frame during movement of the first door leaf from the partially closed position to a fully closed position. The distal end of the second pull arm move along the guide member during closing of the second door leaf at least initially in a direction towards the first edge of the door frame. A closure sequence control mechanism has a blocking condition in which it prevents movement of the distal end of the second pull arm towards the first edge of the door frame and thereby prevents closing of the second door leaf and has a releasing condition in which it permits movement of the distal end of the second pull arm towards the first…
