FIG. 1 shows a schematic front view of a drive device 1 with swing door. The door has a rotary wing 2, which is pivotally mounted on a vertical edge in bands 22 on the frame 21 about a vertical Türachse. The rotary wing 2 is equipped with a drive device 3 mounted on the overhead.

The drive device 3 has a door drive housing 4, in which an output shaft 41 is rotatably mounted on. With the output shaft 41, a sliding arm 42 is non-rotatably connected, which has at its free end a slider 43 which is slidably guided in a slide rail 44 and rotatably connected thereto for this purpose with a slider. In the door drive housing 4 are in FIG. 3 illustrated coil spring 34 as energy storage, an electromechanical drive motor 31 and a hydraulic damping device 32a, 32b arranged with an electrically switchable valve 33 as a holding device, which cooperate with the output shaft 41, respectively.

An electric door opener 37 is arranged opposite the main closing edge on the stationary frame at the level of the door lock 23. In the closed position of the rotary wing 2 of the electric door opener 37 acts to lock and unlock the wing 2 with the latch of the door lock 23 together.

In the area of the door, a control device 5 is arranged stationarily in the hand area. The control device 5 has a housing with an entitlement switching device 52 and emergency release device 51 arranged therein. Authorized switching device 52 is designed as a code keyboard, but may also be designed as a key switch or code card terminal. The emergency release device has an emergency button 51, which with a destructible seal eg a transparent plastic hood, can be secured against misuse. Via a cable 53, the control device 5 is connected to the drive device 3. To compensate for the rotational movement of the door leaf 2, a flexible cable transition 53 a is provided, which, as in FIG. 1 shown, resting in the region of the secondary closing edge, the door leaf 2 and the frame 21 is mounted connecting. In one opposite FIG. 1 modified embodiment, the flexible cable transition 53a may also be optically hidden in the minor closing edge, for example, in a groove of the frame 21, sunk.

The drive device 3 may be a device constructed similarly to a conventional revolving door drive, e.g. around a hydraulic swing door drive. The drive device 3 functions in such a way that the door leaf 2 is blocked in a closed position by the holding device 33. Upon manual actuation of the entitlement switching device 52, the control device 5 releases the holding device, whereupon the stored energy in the energy storage 34 acts on the door 2 in the opening direction by the energy storage 34 acts on the output shaft 41 in the opening direction. The closing of the wing 2 takes place with the supply of external energy by the hydraulic pump 31, at the same time the energy storage 34 is charged.

With the holding device, the door leaf 2 can be blocked during or after opening in any position by the electrically switchable valve 33 of the holding device, the hydraulic damping device 32a, 32b blocks. In addition to the electrically switchable valve 33 is arranged as a further holding device in the frame 21 at the main closing edge of the electric door opener 37 as a locking device. The door opener 37 cooperates in the closed position for locking the rotary vane 2 with the door lock 23 arranged on the main closing edge of the vane 2. For locking and unlocking, the control device 5 controls the door opener 37. The holding device can in opposite FIG. 1 modified versions can be designed as a holding device with door opener 37 or as a holding device with valve as a holding element.

In order to spend the door 2 in the closed position, the control device 5 controls the drive motor 31. The drive motor 31 acts in the closing direction on the closer shaft 41, wherein the door 2 is closed by the resulting forced movement of the sliding arm 42. At the same time, the energy accumulator 34 is charged by tensioning the shutter spring.

In the in FIG. 1 shown mounting method, the so-called blade assembly, the door drive housing 4 is mounted on the door 2. Here, the slide rail 42 is mounted on the frame 21. The assembly can be done both on the hinge side and on the opposite side of the tape.

In alternative embodiments, instead of a Gleitarmgestänges 42 also a Scherenarmgestänge be used. An application of the invention is also possible on double-leaf doors, which may additionally be equipped with a closing sequence control.

FIG. 2 shows the schematic view of a drive device 1 with the so-called head mounting of the drive device 3 at one of the representation in FIG. 1 analogously designed swing door. Here, the door drive housing 4 is mounted on the frame 21 and the slide rail 44 resting on the door 2. The control device 5 is at least partially integrated into the door drive housing 4. It has a movement detector 54 attached to the door drive housing 4, for example infrared detector or radar detector, and a fire detector 56 mounted in the vicinity of the door for controlling the drive device. For bidding the door on both sides, a motion detector 54 can be arranged on the inside and on the outside. It is also possible to arrange a motion detector 52 on one side of the door, eg the outside, and a motion detector 54 on the other side, eg the inside.

On the door 2 is in FIG. 2 a cooperating with the control device 5 safety sensor 55 is arranged. The safety sensor 55 may be single-sided or double-sided on the door leaf 2 in the region of the upper horizontal edge be arranged and is designed for edge protection during the opening and / or closing movement. If the safety sensor 55 detects an obstacle in the swiveling range of the door leaf 2, it generates a signal for switching the holding device and / or for switching the drive motor, so that the swiveling movement of the door leaf 2 is stopped by the holding device and / or reversed by the drive motor 31 ,

In the illustrated closed position, the holding device blocks the door leaf 2. A user is detected by the motion detector 54 when approaching the door. Thereafter, the control device 5 releases the holding device, and the door 2 is opened by implementing the energy stored in the energy storage 34. After the expiry of a presettable time of the door 2 is closed under the action of the drive motor 31 and the energy storage 34 is recharged.

The emergency opening of the door is done by the fire detector 56, which generates a signal to release the holding device in case of fire, whereupon the door 2 opens automatically under the action of the energy storage 34. The signal for releasing the holding device may also be provided by a safety device connectable to the triggering device, such as e.g. a safety device of a smoke-heat extraction device or rescue-route safety device, are generated. As a result, the emergency route in case of fire and / or emergency can be opened from a central point. In case of power failure, the holding device is designed so that it automatically releases the door.

In a modified embodiment, the holding device can be arranged at least partially outside the door drive housing 4 or be connected to a holding element arranged outside the door drive housing 4, eg the electric door opener 37, or be designed as a door opener 37. It is provided that the holding device cooperates with a holding magnet and / or the door opener 37, preferably quiescent door openers, for blocking and releasing the door leaf 2 in the closed position of the door leaf 2.

FIG. 3 shows the schematic structure of the drive device 3. The drive device 3 has a preferably cylindrical housing 35 with axially guided axially displaceable piston 36 therein. The piston 36 divides the housing 35 into two hydraulic chambers 39a, 39b corresponding to hydraulic lines 32a, 32b and filled with suitable hydraulic medium. In the in FIG. 3 right hydraulic chamber 39b is arranged a coil spring 34 as energy storage. The coil spring 34 is supported at one end on the housing wall and at the other end on the piston 36. On an inner wall of the piston 36, a gear meshing with a gear 45 is formed. An output shaft 41 mounted in the housing 35 engages in the interior of the piston 36 and is rotatably connected to the gear 45, so that the axial movement of the piston 36 is converted by the transmission in a rotational movement of the output shaft 41.

In the in FIG. 3 Upper hydraulic line 32a is a driven by the electromechanical drive motor pump 31 is arranged. To close the door 2, the pump 31 of the in FIG. 1 controlled control device 5, whereupon it promotes the hydraulic medium from the hydraulic chamber 39b in the hydraulic chamber 39a. This increases the static pressure in space 39a, and piston 36 is moved axially against the force of spring 34. The spring 34 is elastically deformed while storing mechanical energy and the volume of the hydraulic chamber 39b is reduced. Through the transmission of the piston 36, the output shaft 41 is rotated in the closing direction due to the axial piston movement. By the rotatably connected to the closer shaft 41 sliding arm 42 while a force in the closing direction is transmitted to the door 2. Is the door 2 in the closed position, the piston 36 is in his in FIG. 3 right end position, and the energy storage 34 is loaded.

The discharge of the energy storage 34 is hydraulically damped by the hydraulic medium via the in FIG. 3 lower hydraulic line 32b flows from the hydraulic space 39a into the hydraulic space 39b. In this case, the output shaft 41 of the moving under the action of the spring 34 piston 36 in the opening direction rotated and thus the door 2 opened. If the electrically switchable valve 33 of the holding device arranged in the lower hydraulic line 32b is closed, the replacement of the hydraulic medium is prevented. The piston 36 can not move axially now due to the bilateral static pressure of the pressure chambers 39a, 39b, and the door 2 is held. The blocking of the piston 36 and thus the door leaf 2 can be done in any axial position.

In opposite FIG. 3 modified versions, the movement of the piston 36 can also be blocked by an interacting with the piston 36 electromechanical locking device. In this case, for example, a piezoelectric actuator or a magnetostrictive element can be used as a latching element.

In further embodiments may be provided to close the door leaf 2 instead of the pump 31, a directly or via a transmission with the piston 36 cooperating electromechanical drive, wherein the drive is not designed to be self-locking. The energy storage 34 may also have another storage element, such as coil spring or gas spring.
