In the exemplary embodiments in FIGS. 1 to 6, rails 3 and 103 with a plurality of chambers 7 , 8 of similar construction are used. The rails each have a multi-chamber housing with a plurality of chambers extending in the longitudinal direction of the rail. The locking device is arranged in a chamber 7 . The sliding arm 2 is guided in an adjacent chamber 8 . Between the chambers 7 , 8 , two opposite web edges 28 , 29 are arranged. They delimit an opening which extends in the longitudinal direction and with which the chambers 7 , 8 are connected to one another.

The chamber 13 has a slot 9 which is accessible from below and into which the slide arm 2 engages from below with a slider attached to its free end. The slider can be designed as a roller 10 or as a sliding block 110 .

The embodiment of FIG. 2 also shows a locking device integrated in a corresponding slide rail 107 . It consists of an electric magnet 70 , a stop lever 115 and another lever 106 and egg ner designed as a compression spring 150 and a return spring 160th These components are also arranged in a slide 120 lockable position within the slide rail 107 in a selectable position.

The electromagnet 70 is also fixed in the carriage 120 . The lever 106 is connected between the electromagnet 70 and the spring 150 . The lever 106 is designed as a two-armed lever with the arms 106 a and 106 b, which is articulated in the carriage 120 . Its pivot point 112 is spaced apart from the electromagnet 7, so that the lever 106 b cooperates with the electromagnet 70 via the lever arm 106th

The stop lever 115 is articulated with its end remote from the electromagnet 70 and left in FIG. 2 in the carriage 120 at 113 . The articulation point 113 is arranged at a distance from the articulation point 112 of the lever 106 . The spring 150 is arranged between the free end of the stop lever 115 and the lever arm 106 a. It is supported on the one hand on the stop lever 115 and on the other hand on the lever arm 106 a.

In order to limit the deflection of the stop lever in the path of movement 11 of the slider 110 , a limiting pin 121 is provided within the spring 150 , which is fixed at one end to the stop lever 115 and is guided displaceably at the other end in the lever arm 106 a and has a head 122 cooperating with the lever arm 106 a as a limit stop.

The return spring 160 engages the lever 106 and acts on it for rotation in the counterclockwise direction, so that the lever arm 106 b bears against the electromagnet 7 . In the illustrated embodiment, the return spring 160 is designed as a pressure spring acting on the lever arm 106 a. Alternatively or additionally, it can be configured as a tension spring acting on the lever arm 106 b.

The stop lever 115 is formed in the region of its free end 15 b as a stop which protrudes into the movement path 11 of the slider 110 arranged at the end of the sliding arm 2 . In the illustrated embodiment, the impact lever 115 is cranked in the region of the end 15 b into the movement path 11 . In the position a shown in FIG. 2, the bent portion interacts with the slider 110 as a stop.

In the embodiment shown in FIG. 2, the slider 110 engages in the downward-facing guide slot in the rail housing. The movement path 11 runs in the rail housing below the locking device arranged in the slide 120 . The guide rail 107 is formed symmetrically to the longitudinal center plane in the case shown. This creates the possibility that the rail 107 can be mounted rotated about its vertical axis for left / right use of the closer.

. This device of Figure 2 operates as follows:
When the door 4 is opened, the slider 110 attached to the sliding arm 2 moves in the movement path 11 in the illustration in FIG. 2 from right to left and in a corresponding manner when closing from left to right.

When the electromagnet 70 is energized, the lever arm 106 b adheres to the electromagnet 70 ; ie the locking device is switched on. When the door 4 is rotated in the closing direction under the action of the closing moment applied by the door closer 1 , the slider 110 runs from its position b in the direction of the cranking of the stop lever 115 and finally comes to a stop there on the surface 35 . The closing movement of the door 4 is thus stopped. The door 4 is thereby kept open in the corresponding position.

The door 4 can now be closed by hand overpressure even when the electromagnet 70 is switched on. This overpressing is carried out by applying a greater closing torque to the door 4 than by the door closer 1 . The interacting with the offset of the stop lever 115 in the stop slider 110 now deflects the stop lever 115 against the action of the spring 150 in the counterclockwise direction from the movement path 11 and passes the offset forming the stop. The spring 150 is compressed during the deflection of the stop lever 115 . Here, the Neten with the Elektromag 70 cooperating lever 106 remains stationary stick to the electromagnet. 7

If the electromagnet 70 is not energized, the locking device is switched off. The lever 106 is then no longer attracted to the electromagnet 70. When the door 4 is closed under the action of the closing torque brought up by the door closer 1 , the slider 110 can pass the stop lever 115 or the stop 15 b forming the stop. The stop lever 115 is rotated counterclockwise and the lever 106 clockwise against the action of the return spring 160 , the lever arm 106 b lifting off from the electric magnet 70 and the spring 150 not being compressed.

When the door 4 is opened by hand, the slider 110 can easily pass the stop 15 b during its movement in FIG. 2 from right to left, both when the electromagnet 70 is switched on and when it is not switched on, in which case the stop 15 b is in each case from the Path of movement 11 is deflected. With the magnet 70 turned on when passing the slider 110 to the impact lever 115 with compression of the spring 150 rotates counterclockwise ge, the lever 106 remains stationary on the electromagnet 70 . When the electromagnet 70 is switched off, the stop lever 115 is rotated counterclockwise and the lever 106 clockwise against the action of the return spring 160 when passing the slider 110 , the spring 150 not being further compressed.

The electromagnet can be coupled to a smoke detector (not shown) or an external switch. In an emergency, the electromagnet is switched off automatically or by operating the switch by hand, thus releasing the position of door 4 . However, as stated above, the determination can also be suppressed by hand.

The carriage 120 can be adjusted within the rail housing 108 along the movement path 11 and fixed in a selectable position. The carriage 120 is fixed by means of a fastening screw 180 . The fastening screw can be designed as a clamping screw, in the exemplary embodiment shown, the screw 180 is accessible through the movement path 11 through the guide slot in the rail housing. With the Klemmverbin extension, it is possible to adjust the carriage 120 or the opening angle of the door 4 continuously.

In the embodiment of FIG. 3, a locking device integrated in the slide rail 103 is also provided. It consists of an electric Magne th 70, a stop lever 215 and a compression spring 250 and a rear-spring 260th These components are likewise arranged in a carriage 220 which can be fixed in the rail 103 , the electromagnet 70 being fixed in the carriage 220 .

In contrast to the previous embodiment in Fig. 2, the impact lever 215 is articulated with its end 216 on the anchor plate 272 . The compression spring 250 overlapped with one end 253 in a statio nary in the slide 220 bearing the 254th At its other end 251 it is supported on a bewegli chen bearing plate 265, which has on its side facing away from a knife-edge bearing 266 for the stop lever 215th The cutting edge bearing 266 engages in a corresponding bearing recess 267 on the stop lever 215 . The stationary spring bearing 254 has a guide into which an extension of the bearing plate 265 engages, so that the bearing plate 265 is guided coaxially with the compression spring 250 . The bearing recess 267 is arranged in the lever 215 in an area between the articulation point 216 and the stop cam 215 a.

Under the action of the spring 250 , the stop cam 215 a protrudes into the movement path 11 of the slider 110 . The free end 217 of the lever 215 stands against a catch 218 in the carriage 220 .

The device works as follows:
When the power is on, the lever 215 adheres to the electromagnet 70 . If, when the door 4 is closed, the slider 110 comes into the stop position a with the stop cam 215 a, the door 4 can no longer be closed under the action of the door closer 1 .

The door 4 remains locked until the energization of the electromagnet is switched off or the door 4 is pressed shut by hand.

When the electromagnet 70 is switched off , the armature plate 272 lifts off when the slider 110 is passed . The stop lever 215 is rotated counterclockwise. The cutting edge bearing 266 forms the fulcrum.

When overpressing by hand with the electromagnet 70 switched on , the anchor plate 272 does not lift off when it passes the slider 110 . Lever 215 rotates counterclockwise with compression of spring 250 . The pivot point forms the pivot point 216 .

In the embodiment of FIG. 4, an electromagnet 70 and a stop lever 415 is also provided, which is mounted in the articulation point 416 stationary to the electromagnet. The components are also arranged in a locking screw 480 lockable carriage.

The stop lever 415 is designed as a one-armed lever. It is angled essentially S-shaped in the middle and encompasses the electromagnet 70 . At its free end, the lever 415 is designed as an anchor plate 472 , which interacts with the side of the electromagnet 70 facing away from the guideway 11 .

The stop cam is formed as a molded on the lever 415 nose 415 a. It is arranged in the area between the articulation point 416 and the S-shaped bend.

The device works as follows:
When the power is on, the lever 415 adheres to the electromagnet 70 . When the slider 110 comes into abutment position a when the door 4, the door 4 can not close under the action of the door closer 1 and is determined in the respective open position.

The door 4 can then only be closed by switching off the current of the electromagnet 70 or by pushing the door 4 over by hand. In both cases, the lever 415 is deflected counterclockwise by 416 when passing the slider and is thereby torn off by the electromagnet 70 .

The device functions in a corresponding manner when the door 4 is opened. Even then, when passing the slider 110, the lever 415 rotates counterclockwise while lifting off the electromagnet 70 .

In the embodiment of FIG. 5, the locking device is also integrated in the slide rail 103 and interacts with the slider 110 . The Vorrich device has a movable electromagnet 670 , which is guided in the chamber 7 pa rallel to the path of movement of the slider 110 . The magnet 670 cooperates with an anchor plate 672 rigidly connected to the slider 110 via a pin 111 , which is guided in the same chamber 7 as the magnet 670, so that it can slide. Of course, when using a different rail, the electromagnet 670 and the armature plate 672 can also be guided in the same chamber as the slider 110 .

In contrast to the preceding exemplary embodiments, the electromagnet 670 is moved together with the slider 110 at least in a limited opening area of the door 4 . An adjustable in the chamber 7 stop device 680 limits the movement of the electromagnet 670 in the closing direction. A return spring 660 urges the electromagnet 670 against the device 680 .

When opening the door 4 , the slider 110 moves to the right in the illustration in FIG. 5 and takes the electromagnet 670 which is in the stop from a certain opening angle of the door 4 .

When door 4 is closed, slider 110 moves to the left. If the current is switched on, the armature plate 672 adheres to the electromagnet 670 , so that the electromagnet 670 is also moved.

When the magnet 670 comes to a stop with the stop device 680 during the closing movement, the movement of the unit consisting of magnet 670 and slider 110 is stopped. The slider then remains in the stop position a until the energization of the electromagnet is switched off or the door 4 is pressed shut by hand. In both cases, the armature plate 672 detaches from the electromagnet 670 .

The hold-open angle is adjusted by appropriate adjustment of the stop device 680 . The device 680 is fixed in the illustrated embodiment with a screw 681 .

In the exemplary embodiment in FIG. 6, an anchor plate 672 rigidly connected to the slider 110 is also provided, which is guided in the chamber 7 in which the electromagnet 670 is arranged. This can also be moved at least in a partial area together with the slider 110 or the anchor plate 672 . In contrast to the previous example, the electromagnet 670 is mounted in a carriage 620 . The carriage 620 can be locked in the chamber 7 in a selectable position. The electromagnet 670 is supported on a damper 655 , which is attached to the end of the carriage 620 . A spring 650 is interposed. A microswitch 671 is attached to the other end of the carriage and is connected to the electromagnet 670 .

The device works as follows:
When the door 4 is opened, the slider moves from left to right in the illustration in FIG. 6.

The anchor plate 672 comes into contact with the electromagnet 670 . The common movement is braked by the spring 650 and the damper 655 . With corresponding dimensions of the spring 650 and the damper 655 , the door 4 can be opened more or less beyond the locking angle.

When the electromagnet 670 is turned on, the anchor plate 672 adheres to the magnet 670 , so that the slider 110 is held in the position shown a and the door 4 is fixed in the relevant open position. The door 4 can now be closed in that the energization of the electromagnet ex tern, for. B. switched off via a smoke detector or a switch or the door 4 is pushed over by hand. When the current is switched off, the armature plate 672 lifts off the magnet 670 and the door 4 closes. When pressing over by hand, the unit consisting of slider 110 , anchor plate 672 and magnet 670 is moved to the left against the effect of the spring 650 in FIG. 6. The microswitch 671 is run over. The result of this is that the microswitch 671 switches off the flow of the electromagnet 670 and thereby lifts the armature plate 672 from the electromagnet 670 . Then the door 4 can close under the effect of the door closer 1 .

A microswitch 671 can also be provided in the exemplary embodiment in FIG. 5. For example, the stop device 680 can be mounted with the interposition of a spring, so that when the door 4 is pushed over, the stop can be displaced by hand so far that the microswitch 671 is triggered.

In the embodiment of FIG. 7, the locking device is integrated in a rail 703 . The rail can have a main chamber in which the fixed adjusting device is arranged and the slider is guided. The locking device consists of an electromagnet 770 , a two-armed lever 740 with an anchor plate 772 , a return spring 760 and two slides 715 , 716 with locking cams 715 a and 716 a.

The components are mounted in a carriage 720 in the rail 703 . The Schlit ten 720 can be determined in a selectable position along the rail by a locking pin 780 is provided which engages in a holder 781 in the carriage 720 and in corresponding locking holes 782 in the rail wall.

Of course, the fixation can also be done using a clamping screw.

The slider is designed as a locking slider 710 with two spring-loaded locking cams 711 , 712 , which cooperate with the locking cams 715 a and 716 a of the slider 715 , 716 . The slider 710 moves when opening the door 4 in the Dar position in Fig. 7 to the left, when closing to the right.

The two slides 715 , 716 are arranged in side chambers 704 and 705 in the rail housing 703 . The locking cams 715 a, 716 b protrude into the movement path 711 of the slider 710 .

The slider 716 is designed as an immovable slider by being rigidly attached to the carriage 720 . The other slide 715 is designed as a movable slide. It is slidably arranged on the carriage 720 and can be ascertained via the electromagnet 770 .

When the power is on, the armature plate 772 adheres to the electromagnet 720 . The lever 740 engages with its free end in a locking recess 719 in the movable slide 715 and holds it in the locked position shown in FIG. 7.

In this position, the locking cams 715 a, 716 a are in alignment with one another.

Fig. 7 shows the slider 710 with the locking cams 711 , 712 in abutment with the locking cams 715 a, 716 a.

The locking cams 711 , 712 are arranged at one end of the slider 710 outside the center, so that a further adjustment range is obtained by rotating the slider 710 through 180 °. The trigger torque can be adjusted by different beveling of the cams 711 , 712 . When the current is switched on and the slide 715 is thus blocked, the locking cams 715 a, 715 b block the slider 710 from passing to the right. The door 4 is thereby determined in the open position.

The determination can be solved by switching off the power or by pushing the door 4 over by hand.

When the current is switched off, the blocking of the slide 715 is released by the slide 715 being moved to the right in the illustration in FIG. 9 under the action of the latching slide 710 . The armature plate 772 lifts off the electromagnet 770 and the lever 740 pivots counterclockwise. With the displacement of the slide 715 , the locking cam 715 a comes into an offset arrangement relative to the locking cam 716 a. The slider 710 can rotate a bit counterclockwise about its axis 710 a. In a corresponding manner, the locking cams 711 and / or 712 can also be rotatably supported and deflected. The locking cams 711 , 712 are released from the engagement of the locking cams 715 a, 716 a.

If the door 4 is pushed over by hand when the electromagnet is switched on, the slide 715 remains in the locked position shown in the figure. The lever 740 with the armature plate 772 remains attached to the electromagnet 770 . The locking slider 710 can pass through the fact that the locking cams 711 , 712 are mounted elastically or be movable and can be moved towards one another when overpressed and thus free from the engagement of the locking cams 715 a, 716 a.

In the latching slider 710 shown in FIG. 7, the latching cams 711 , 712 are formed on two arms 713 , 714 articulated on the body of the slider 710 . Between the arms 713, 714 to a transverse pressure spring is supported 750, the arms 713, 714 presses apart the locking cam 711, 712th When the slider 710 passes the locking cams 715 a, 716 a when overpressing, the spring 750 is compressed.

In other versions (see FIG. 8) of the locking slide 710 , the locking cams 711 , 712 can also be connected to one another via elastic connecting webs 715 .

In other versions (see FIG. 10), the locking cams 711 , 712 can also be designed as two opposing slides 717 , 718 , which are acted upon by a compression spring 751 . The spring 751 or the slide 717 , 718 are preferably rotatably mounted on the body of the slider 710 .

In another embodiment of the locking slide (see FIG. 5), the two locking cams 711 , 712 are mounted on arms which are pressed apart by a spring-loaded wedge 719 .

Also in the last-described embodiment in Fig. 7, the door can be opened over the locking angle addition. 4 This is made possible by the fact that the electromagnet 770 is arranged at the end of the movement path of the slider 710 and the slides 715 , 716 are designed to be correspondingly long.

In alternative designs, however, the carriage 720 with the electromagnet 770 can also be arranged in an adjacent chamber outside the slideway 711 .

Of course, versions are also possible in which the door 4 can only be displaced beyond the locking angle to a limited extent. In these cases, the carriage 720 may be located within the slideway 711 , and short sliders 715 , 716 may also be used.
