The subclaims form advantageous embodiments of the invention.

Electromagnetic detents are often used to keep door leaves of fire doors open with door drives open. As a result, corridors can be freely committed, in case of fire, the locking device can be automatically canceled, whereby the door leaves are closed by the door drives. Often these are double-leaf, with a closing sequence control provided doors, whereby the inactive leaf closes before the provided with an overlap, the fold, active leaf. The stand-wing-side slider actuates a triggering device which cooperates with a locking device which acts on the gangway-side door closer. Through this, the closing of the active leaf is prevented when the inactive leaf is in an at least partially open position.

The device according to the invention is suitable for small to very large holding forces, which are required depending on the door leaf sizes and weights. It is simple and easy to adjust. Due to the overload protection, the door system is protected from damage by pressing the door with a detected locking device, and the door can be closed manually by driving over the locking device.

In the following an embodiment in the drawing with reference to the figures will be explained in more detail.

a view according to Fig. 2 , wherein the locking device is run over by overload.

From the Fig. 1 is a two-leaf door with a moving leaf 1 and a passive leaf 2 can be seen with a above the door leaf 1, 2 arranged in or on the door frame slide 9, in which arranged on the slide arms 5, 6 of the door drives 3, 4 slider 7, the eighth are guided. Furthermore, the closing sequence control a triggering device 10, a locking device 11 and the open position of the door 1, 2, the locking devices 12, which cooperate with the sliders 7, 8, disposed within the slide rail 9. The locking device 12 is constructed identically for both door 1, 2.

In the FIGS. 2 to 4 is a section of the slide 9 with the locking device 12 for the passive leaf 1 shown in a sectional view. The locking device 12 is arranged in accordance with laterally reversed arrangement for the active leaf 2 in the slide rail 9. Fig. 2 shows the basic position in which a stop element 14 projects into the path of movement of the slider 7, 8. The locking device 12 may be activated to keep open the door leaf 1, 2.

The locking device 12 has a receptacle 13, which can be moved in the slide rail 9 to determine the desired hold-open position of the door leaf 1, 2 and fixed with a clamping element, not shown, for example, a clamping screw. In the receptacle 13, an electromagnet 21 is arranged, which cooperates with an armature plate 20 arranged on a rod 19 at one end. The rod 19 has at the other end a locking element 15, which is acted upon by an elastic element, the return spring 22, whereby the armature plate 20 is applied to the electromagnet 21. The blocking element 15 is guided in the receptacle 13, wherein this can be formed in the region of the guide by a material insert or a coating for improved sliding properties. On the receptacle 13 a pivotable about an axis of rotation 18 lever 17 is arranged. For the rotation axis 18 a plurality of positions are provided, whereby the locking device 12 can be set for different door weights on different locking forces.

The lever 17 has a recess 16 which cooperates with the blocking element 15. The recess 16 may also have a coating or be formed as a material insert for improving sliding properties. When energized electromagnet 21, the armature plate 20 is held on this, and the locking element 15 is urged into the recess 16 for fixing the lever 17. The displaceably arranged on the lever 17 stop member 14 is urged into the movement path of the slider 7, 8 and thus sets the wings 1, 2 fixed.

If the determination is released when the electromagnet 21 is switched off, the slider 7, 8 acted upon by the door drive 3, 4 pivots the lever 17 over the bevel on the stop element 14 into the release position, as shown in FIG Fig. 3 is shown. By pivoting the lever 17, the displaceable by switching off the electromagnet 21 locking element 15 is urged out of the recess 16 against the spring 22. The slider 7, 8, the stop member 14 go under, after which the lever 17 through the locking member 15, which pushes through the spring 22 in the recess 16, in the normal position according to Fig. 2 swings back. The armature plate 20 comes into abutment with the electromagnet 21, and the locking device can be activated by energizing the electromagnet.

The locking device 12 has an overload protection, which can be triggered by pivoting the door 1, 2. This prevents damage to the door wings 1, 2 and the door drives 3, 4, and it is also a conscious driving under the locking device 12, bypassing the electrical release possible. Fig. 4 shows the overload release, the electromagnet 21 is energized and the lever 17 is prevented by the blocking element 15 on pivoting.

For overload protection, the stop element 14 cooperates with an overload element 23 acted upon by an elastic element, for example an overload spring 25, which engages in a recess 24 of the stop element 14. The bias of the overload spring 25 can be adjusted by an adjusting screw 26. This makes it possible to set the release force with which the overload element 23 has to be pressed out of the recess 24. The overload protection triggered by an increased force of the slider 7, 8 on the stop member 14, wherein the overload element 23 is urged out of the recess 24 and the stop member 14 slides on the slider 7, 8. If the slider 7, 8 is moved away from the area below the stop element 14, then the overload element 23 engages through the overload spring 25 into the recess 24, whereby the stop element 14 returns to the blocking position.
