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 edge of the door frame and thereby permits closing of the second door leaf. The closure sequence control mechanism changes from its blocking condition to its releasing position by application of a force directed from the first edge of the door frame towards the second edge of the door frame. A coupling mechanism is coupled to the distal end of the first pull arm when the first door leaf attains the partially closed position and converts movement of the distal end of the first pull arm towards the first edge of the door frame to a force directed towards the second edge of the door frame. A connection piece applies force from the coupling mechanism to the closure sequence control mechanism for changing the closure sequence control mechanism from its blocking condition to its releasing condition.
A door closing arrangement for controlling closure sequence of turnable double doors, where the double doors are provided with a first door closer unit (4) for closing a first door leaf (1) and a first pull arm (5), and a second door closer unit (6) for closing a second door leaf (2) and a second pull arm (7), a guide rail (8) or the like for guiding a distal end (5a, 7a), with regard to the door closers, of the pull arms (5, 7), closure sequence control means (9) which, in the end phase of the closing of the door leaves (1, 2), are arranged so as to cooperate with the distal end (5a, 7a) of the pull arms, and a connection piece (10, 11) for transferring the effect of the distal end (5a) of the pull arm of the first door leaf (1) over to the closure sequence control means (9), whereby the closure sequence control means (9) are arranged so as to prevent the movement of the pull arm end (7a) of the second door leaf (2) in the guide rail (8) until the pull arm end (5a) of the first door leaf (1) has affected the closure sequence control means (9) through the connection piece (10, 11) so that they allow closing of the second door leaf (2), characterized by the combination that the door closer units (4, 6) are, in a way known per se, arranged on the opposite side of the door leaves with respect to the door hinges (3a), i.e. on the opposite side with respect to the opening side of the doors, and that the distal end (5a) of the first pull arm (5) and the connection piece (10, 11) are arranged to cooperate so that in the releasing phase of the closure sequence control means (9) the movement of the distal end (5a) of the first pull arm (5) in the direction away from the closure sequence control means is arranged so as to make the connection piece (10, 11) move towards the closure sequence control means (9).
A door closing arrangement for first and second door leaves that are pivotable with respect to a door frame having first and second edges, the first door leaf being attached to the door frame at the first edge by a first hinge means and the second door leaf being attached to the door frame at the second edge by a second hinge means, the door closing arrangement comprising:
A door installation including:
