"Door co-ordinator for double-leaf doors"

The invention relates to a closing sequence controller for double-leaf doors, in particular escape or fire doors that are automatically closed in the event of danger an arm which is held on the door frame so that it can pivot against the action of a spring and detects an abutment on the doors.

Such closing sequence controllers are arranged to ensure that the door leaf, which has a latch bolt, for example, only slams shut when the other door leaf is already in the closed position. For this purpose, the arm of the closing sequence controller is held with the door leaf open under the action of a spring in such a swiveled-out position that when the wing is automatically closed with a latch bolt lock on a mounted abutment ger from the swiveled arm and is held Festge until the other wing continues in the direction is pivoted to the closed position than the held wing and then grips the arm with a mounted abutment, takes it with it and thereby also releases the wing that was previously held, which is now the

sash pivoted ahead to the closed position follows. The disadvantage of known closing sequence controllers is that for each wing width a certain arm length is required and that accordingly for the different ones in question Cases a larger number of different sized door co-ordinators must be manufactured or stored or that with a uniform arm length of the respective leaf width, the installation position must always be determined anew is.

The object of the invention is to determine the area of application of the closing sequence controller to enlarge and improve this so that it can be used with different widths of door leaves can and is to be mounted largely on prepared holes.

This object is achieved in that the arm is part of a is double-armed lever, the other arm has an adjustable stop.

The stop makes it possible to limit the pivoting angle of the arm grasping the door leaf and to adjust it so - That for a given width of the door leaf, the closing sequence of the two door leaves is regulated in the desired manner will. The adjustable stop not only enables the door co-ordinator to be used for different purposes wide doors, it also gives more leeway with regard to the arrangement of the fitting supporting the arm on the door frame, because the swivel angle is always optimally adapted to the given conditions afterwards can be.

The stop should preferably be a screw which is held in a threaded hole in the other arm

and which is supported e.g. on the fitting that supports the arm.

To prevent unintentional turning of the screw and thus unintentional adjustment of the stop, the screw can have a lock nut.

In the following the invention is explained using an embodiment shown in the drawing tion; it show:

1 shows a view of a closing sequence controller mounted on a door frame,

Pig. 2 shows a plan view of the object according to FIG. 1,

3 shows the object according to FIG. 1 in an enlarged view,

4 shows the object according to FIG. 2 in an enlarged view and partially in section.

In a frame, not shown, are two wings 1, a fire door stored, which closes automatically in case of danger, the two leaves 1, 2 so Pivot in the closed position that first the wing 1, which has a stop strip 3 for the wing 2, in Direction of arrow 4 is moved leading in the closed position, while the wing 2 follows, so that it is against the stop bar 3 of the already closed wing 1 places, at the same time a arranged on the wing 2, Closing mechanism not shown in detail, e.g. a latch bolt, which locks the door.

A fitting 6 is fastened to the upper door frame 5 with screws. The fitting 6 has a pivot bearing 8 for a elongated arm 9, which in the illustrated embodiment is a tube in which one does not illustrated spring supported buffer rod 10 is performed.

The arm 9 is under the action of a in the area of Pivot bearing 8 arranged, on the one hand on the fitting 6 and on the other hand on the arm 9 supported spring 11 after outside pivoted into the position shown in the figures.

The arm 9 is part of a double-armed lever, the other angled arm 12 has a threaded hole for a Has stud 13 which can be fixed in the threaded hole with a lock nut 14. That is about the Threaded bore in the direction of the fitting 6 also extending end, the stud screw 13 is immediate supported on the surface of the fitting 6 and forms a stop which limits the pivoting movement of the arm 9 .

The closing sequence controller shown works as follows: When the leaves 1, 2 are open, the arm 9 is activated the spring 11 is held in the position shown in FIGS. If, in the event of danger, the wings 1, close automatically, and e.g. leaf 2 leads, it hits with an abutment 15 attached to the top of the wing 2 and protruding over the upper edge on the buffer rod 10, which brakes the pivoting movement of the wing 2 and holds it in place until the wing 1 reached the position shown in Fig. 2 and with a

also attached to its upper side and the upper edge protruding abutment 16 detects the arm 9 and pivoted this in the direction of arrow 4. The wing 2 is also released, so that it follows the leading wing 1
can follow. When the door is closed (FIG. 1), the arm 9 assumes the position shown in FIG. 4 with dash-dotted lines.
