Description

The invention relates to a door drive device having the features of the preamble of patent claim 1.

Door drives with disengageable force-transmitting linkage are already known, for example from the documents DE 212 280 A , DE 1 262 533 A , DE 19 01 664 A , EP 2 392 757 A1 , JP 2010 - 112 052 A and JP 2010 - 236 186 A .

The documents DE 1 262 533 A and DE 19 01 664 A describe door drives in which the force-transmitting linkage assumes a dead center position in the disengaged position. The dead center position is switched on or off automatically at a predetermined door opening angle when the clutch is disengaged/engaged, based on the respective angular position of the linkage in the relevant door opening position.

The documents DE 212 280 A , EP 2 392 757 A1 , JP 2010-112 052 A and JP 2010 - 236 186 A describe door drives in which the force-transmitting linkage is held in the disengaged position by a mechanical stop device. The mechanical anchor device is switched on and off automatically when the clutch is disengaged/engaged.

The disadvantage of the known systems is that the force-transmitting linkage is accessible for manipulation in the disengaged position.

The invention is based on the object of creating a door drive device with a linkage that can be engaged and disengaged, which has increased security against manipulation.

This object is achieved with the subject matter of patent claim 1.

The object is a drive device for a door of a building with a door leaf mounted in a stationary door frame so that it can pivot about a vertical door axis. The door drive device includes a main drive and an auxiliary drive.

The main drive is designed to act on the door leaf in terms of closing movement and/or opening movement and/or damping and/or damping, preferably as a manual closing spring drive or as an electromotive door drive. It has a drive unit and a power transmission device. The power transmission device has a linkage and a linkage bearing, preferably a slide rail and a slide arm guided therein.

The auxiliary drive is designed to act on the door leaf in terms of closing movement and/or opening movement and/or damping on closing and/or damping on opening. It has a drive unit and a power transmission device. This power transmission device of the auxiliary drive has a linkage and a linkage bearing and can be automatically engaged and disengaged with the drive unit of the auxiliary drive during the opening and/or closing process. The coupling/decoupling point is formed between the linkage and the linkage bearing or between the linkage and the drive unit of the auxiliary drive.

Furthermore, the drive device has a holding device for the disengaged linkage of the auxiliary drive. Depending on the angular position of the door leaf, the holding device can be positively switched into a blocked position and a release position in such a way that the holding device holds the disengaged linkage in a predetermined linkage position in its blocked position and does not hold the disengaged linkage in its linkage position in its release position.

It is essential that the power transmission device of the main drive and/or a component connected to the output of the main drive and/or an electrical sensor device detecting the position of the door leaf controls the holding device of the disengaged linkage of the auxiliary drive.

The control of the holding device ensures that when the door drive device is operated during the opening process and/or during the closing process, the switching of the holding device takes place reliably and automatically, preferably in the sense of a forced control.

With regard to versions in which the power transmission device of the main drive controls the holding device, it can preferably be provided that the power transmission device of the main drive is designed as a slide arm and slide rail, with the slide arm being drive-connected at one end to the output of the drive unit of the main drive and to its free end is guided in the slide rail and that the sliding arm controls the holding device of the uncoupled linkage, in which the sliding arm interacts with a release device of the holding device.

As far as the holding device is concerned, it can be provided in preferred embodiments that the holding device is designed as a composite holding device which has a first holding device which can be switched into the blocked position and the released position and a second holding device which can be switched into the blocked position and the released position. It can be provided in particular that the first holding device is designed as a dead center position device and/or as a stop device and/or as a latching device and/or as a magnetic device, and/or that the second holding device is designed as a dead center position device and /or is designed as a stop device and/or as a latching device and/or as a magnetic device. Alternatively or additionally, it can be provided that the first holding device is designed as a dead center position device, in that the linkage that can be coupled/disengaged forms, in connection with the output of the drive assembly, a toggle lever device that can be switched automatically depending on the angular position of the coupling/disengageable linkage .

In preferred embodiments it can be provided that the second holding device is designed as a stop device, in that the second holding device has a lever device which has a locking lever acting on the disengaged linkage.

As far as the configuration of the locking lever is concerned, it can be provided in preferred embodiments that the locking lever has a first section which interacts as a locking element with the disengaged linkage and has a second section which has a control link or works together with a control link which is on the wing side and/or or can be supported on the frame side and is forcibly controlled by the opening and closing operation of the door. In a preferred further development it can be provided that the blocking lever is designed as a two-armed lever which has at its one end the first section which interacts with the disengaged linkage and at its other end has the second section which interacts with the control link. In a preferred development, it can also be provided that the control link interacts with the locking lever in that the control link is mounted in a pivot bearing arranged on the locking lever.

Particularly advantageous are embodiments that provide not only one holding device, as is known per se, but two holding devices for fixing the disengaged linkage. This means that manipulation is more difficult. The second holding device represents an additional holding device, so that at least two holding devices act on the uncoupled linkage. Manipulation of the disengaged linkage is made more difficult because not only the effect of a single holding device has to be eliminated for manipulation. An essential aspect is when it is provided that the first holding device and the second holding device are designed to be switchable independently of one another, in that at least one of the two holding devices can be switched independently of the other holding device.

In embodiments with an assembled holding device, it can advantageously be provided that the holding device is switched to the locked position when the first holding device or the second holding device is switched to the locked position or when the first holding device and the second holding device are switched to the locked position at the same time or in a predetermined sequence.

Particularly advantageous are embodiments that provide that the holding device has a first release device and a second release device that can be actuated automatically and/or forcibly during the closing and/or opening process of the door leaf depending on the active position of the door leaf. In this case, the holding device is designed in such a way that the holding device can only be switched into the release position by actuating both release devices. The fact that the holding device has at least two release devices, i.e. a plurality of release devices, which must be actuated in a specific way in order to switch the holding device, increases security against manipulation. The term “release device” is understood to mean an actuating device of the holding device, which can be actuated to switch the holding device from the blocked position to the released position. It is essential that several such actuating devices are provided, which are preferably to be actuated separately and independently of one another in order to obtain the release position of the holding device. During the opening and closing process, the release device is actuated automatically and/or forcibly, preferably by the movement of the door and/or by the door positions passed through during the movement of the door. This automatic and/or compulsory actuation can take place through certain components of the door drive device and/or through the door itself. Appropriate switch and/or sensor devices can interact with moving components. The switching of the holding device then takes place during operation in each case by the corresponding automatic and/or automatic actuation of the respective release devices. The holding device is thus protected against manipulation by arbitrary actuation.

Switching the holding device from the blocking position to the release position can depend on the switching times, ie the times at which the release devices are actuated, namely the actuation time of the first release device and the actuation time of the second release device. The actuation times can be, for example, in a certain order or the actuation times can be at the same time. Additionally or alternatively, a temporal relationship between the actuation states of the release devices can also be important, e.g. the fact that the respective duration of the actuation of the release devices can be of different lengths and/or overlap in time or in a specific order over a specific period of time simultaneously overlapping or take place one after the other.

Particularly in connection with assembled holding devices, it can advantageously be provided that the first release device and/or the second release device are or is inaccessible for manual operation from the outside through a cover or other components of the door drive device.

As far as the design of the release device is concerned, it can be provided in preferred embodiments that a release device is formed as part of the holding device or is connected to the holding device, and/or that a first release device is formed as part of the first holding device or is connected to the first holding device and/or that a second release device is formed as part of the second holding device or is connected to the second holding device.

In a preferred development, it can be provided that the release device is designed in such a way that the holding device can be released by actuating the release device, and/or that the first release device is designed in such a way that the first holding device can be released by actuating the first release device, and/or that the second release device is designed in such a way that the second holding device can be released by actuating the second release device. Additionally or alternatively, it can be provided that the release device, preferably the first and/or the second release device and/or the holding device, preferably the first and/or the second holding device, can only be actuated at a predetermined door opening angle when the door drive device is in the installed position and/or is releasable. Provision can also be made for the release device, preferably the first and/or the second release device and/or the holding device, preferably the first and/or the second holding device, to prevent and/or impede improper manual operation from the outside by means of a cover panel is covered.

With regard to the release device, it can also be provided in advantageous embodiments that the release device, preferably the first and/or the second release device and/or the holding device, preferably the first and/or the second holding device, is provided by a component of the door drive device and/or by the drive unit and/or is covered by the power transmission device to prevent and/or impede improper manual operation from the outside.

Particular security against manipulation is obtained with designs that provide that the holding device has a first release device and a second release device, which can be actuated automatically and/or forcibly when the door leaf is closed and/or opened, depending on the angular position of the door leaf, and that the holding device is designed in such a way that the holding device can only be switched into the release position by actuating both release devices. In a preferred development, it can be provided that the holding device is designed in such a way that to switch the holding device to the release position, the actuation of the first release device and the actuation of the second release device are required at the same time, or the actuation of the first release device and the actuation of the second release device in one predetermined order one after the other is required.

An essential aspect here is when the preferred embodiments provide that the first release device and the second release device are arranged at different points of the holding device, preferably at a mutual distance.

In particularly preferred exemplary embodiments, the holding device is designed, as already mentioned, as a composite holding device made up of a first holding device and a second holding device. In the specific preferred embodiments, the first holding device is formed by a dead center position device of the preferably provided toggle lever mechanism of the linkage of the auxiliary drive. The dead center position occurs automatically in each case at a predetermined angular position of the linkage in the coupling/disengaging position as a result of the respective angular position of the linkage. It is released by changing the angular position of the Linkage, ie for example as intended when immersing the free end of the decoupled angle arm in the associated slide rail. The free end of the disengaged angle arm thus forms the release device for this first holding device, because when the free end is pivoted out of the angular position by attacking the free end, this first holding device is released.

The second holding device in the specific embodiments can preferably be formed by a blocking arm of a stop device. The locking arm holds the disengaged linkage of the auxiliary drive in the predetermined angular position, which corresponds to the angular position of the linkage during engagement/disengagement. This second holding device is released by pivoting the blocking arm. In a specific embodiment, the blocking arm is designed as a blocking lever which interacts with a control lever which is actuated by the sliding arm of the main drive. The control lever thus represents the release device for the locking arm of the second holding device.

In preferred embodiments, a predetermined order is required for releasing the restraints. In the specific embodiment described, the locking arm of the anchor device must be released first and then or at least simultaneously the dead center position device of the toggle lever configuration of the angle arm must be released by actuating the free end of the disengaged linkage.

Regarding the power unit of the main drive:

The drive unit of the main drive can be designed as a spring accumulator, which is forcibly charged during the opening process and then drives the door to close when it is discharged. However, designs are also possible in which the drive unit is designed as a spring accumulator which is charged when it is closed and then drives the door to open when it is discharged.

The drive unit can have a damping device, preferably a hydraulic damping device, for damping the closing movement and/or the opening movement. The charging of the spring accumulator can be compulsorily carried out both in the case of the closing drive and in the case of the opening drive when the door is manually operated, i.e. in the case of the closing drive compulsorily during the opening process and in the case of the opening drive compulsorily during the closing process. However, an electric motor can also be provided for charging the spring accumulator, and versions are also possible in which a preferably electrically switchable locking device is provided, with which the spring accumulator is kept in the charged state in order to, with appropriate switching of the locking device, during the closing process and/or to be switched on during the opening process for closing or opening or to serve as an emergency closer or emergency opener. The locking device can also be designed to be mechanically switchable, e.g. also forced to switch automatically.

As an alternative or in addition to the spring accumulator, the drive unit of the main drive can also have an electromechanical motor with which the opening process and/or the closing process takes place by an electric motor.

Regarding the power unit of the auxiliary drive:

The drive unit of the auxiliary drive can be designed as a spring accumulator, which is forcibly charged during the opening process and then drives the door to close when it is discharged. However, designs are also possible in which the spring accumulator is charged when it is closed and then drives the door to open when it is discharged.

The drive unit can have a damping device, preferably a hydraulic damping device, for damping the closing movement and/or the opening movement.

The spring accumulator can be charged when the door is operated manually, i.e. when it is opened or closed. However, an electric motor can also be provided for electromechanically charging the spring accumulator.

Designs are also possible in which a preferably electrically switchable locking device is provided, with which the spring accumulator is kept in the charged state in order to be switched on with appropriate switching of the locking device during the closing process and/or during the opening process for closing or opening or as a To serve emergency closer or emergency opener. The locking device can also be designed to be mechanically switchable, e.g. also forced to switch automatically, for example in connection with the coupling/decoupling of the linkage or when a certain door opening angle is reached.

As an alternative or in addition to the spring accumulator, the drive unit can also have an electromechanical motor with which the opening process and/or the closing process takes place by an electric motor.

The auxiliary drive is intended to supplement the main drive. The auxiliary drive and the main drive are advantageously designed as separate drive devices which interact in combination with one another. They are preferably mounted next to each other on the door. The components of the auxiliary drive and main drive are preferably separate structural units, but can be connected to one another, for example by mutual attachment and/or connection points and/or by common bearing devices or covering devices.

The drive device of the auxiliary drive consists of a drive unit and a power transmission device. The drive unit of the main drive is also composed of a drive unit and a power transmission device.

Significant advantages result if the auxiliary drive is designed in such a way that the power transmission device has an on/off coupling point, so that it is possible to switch on the auxiliary drive only in a specific door opening area during the closing process and/or during the opening process, in order to activate the main drive only in this specific area to support.

Regarding the power transmission:

In the preferred embodiments of the drive device according to the invention, each drive unit is assigned a power transmission device. The power transmission device can be composed of a linkage and a linkage bearing. The linkage has a connection end for connection to the output of the associated drive unit. At the end facing away from the drive assembly, the linkage is mounted in the linkage bearing. The linkage can be designed as a sliding arm or as a scissor linkage. The linkage bearing can be designed as a slide rail or pivot bearing. The linkage forms the power-transmitting connection of the power transmission device. It connects the output of the drive unit with the linkage bearing in a force-transmitting manner.

It should be pointed out that the linkage can also have a further support in addition to the connecting end of the linkage that can be connected to the output of the drive unit. This further support can be the support in a bearing which is designed to be stationary with the support of the drive unit. For example, such designs are possible with a sliding arm, which engages with its connection end on a linear output of the drive unit and has a further connection end protruding at an angle in order to be supported in a bearing which is stationary with a bearing in which the drive unit is supported.

The power transmission device serves to transmit the driving forces between the door leaf and the frame. If the drive unit is mounted on the wing, the linkage bearing is to be mounted on the frame. If the drive unit is mounted on the frame, the linkage bearing must be mounted on the wing. The mounting arrangement on the frame and sash can be selected for the main drive in the same way as for the auxiliary drive. The arrangement may be such that the power packs are both wing mounted and the linkage bearings are both frame mounted, or conversely, the power packs are both frame mounted and the linkage bearings are both wing mounted. However, the arrangement can also be selected differently from one another, i.e. the drive unit of the auxiliary drive on the wing and the drive unit of the main drive on the frame and the linkage bearing of the auxiliary drive on the frame and the linkage bearing of the main drive on the wing or vice versa, namely the drive unit of the auxiliary drive on the frame and the drive unit of the main drive on the wing and the linkage bearing of the auxiliary drive on the wing and the linkage bearing of the main drive on the frame.

As far as the terms sliding arm and sliding rail are concerned, it should be pointed out that the free end of the sliding arm is guided in the sliding rail and does not necessarily have to slide in the physical sense. In any case, however, the slide rail has a guide track in which the free end of the slide arm is guided. The free end can be designed as a sliding block, which is actually slidingly guided in the guideway in the physical sense. However, the slider can also be a roller that is guided in a rolling manner in the guideway of the slide rail. The slider can also be a pinion, which is guided in the guideway of the slide rail so that it meshes with teeth or the like. A slider is therefore not necessarily understood to mean a sliding element that slides in the physical sense.

However, the slide arm is always a force-transmitting guide arm and the slide rail is a guide rail, the free end of the guide arm being guided in the guide track of the guide rail.

The guideway of the guide rail can be a linear guideway. However, designs are also possible in which the guide track is designed as a non-linear curved track.

The exemplary embodiment illustrated in the figures is a door drive device which, in the specific case, is designed as a manual door closer device, ie with a closing spring store without a motor drive that can be operated with external energy. The door closer device shown is composed of a main drive 1 designed as a sliding arm door closer and an auxiliary drive 2 which can be designed as a door pull and/or closing damper. This division into main drive 1 and auxiliary drive 2 is essential, ie it is essential that the door closer device is composed of a main drive 1 and an auxiliary drive 2 . This composite door operator is denoted by the reference numeral 10 in the figures and is shown in FIG 1 mounted on a door 3. The door 3 is how 1 shows a pivoting door, which comprises a door leaf 3f, which is mounted via door hinges 3b in a stationary door frame 3r so that it can pivot about a vertical door axis 3a. In the case shown, the door leaf 3f is designed as a pivoting stop leaf. In the case shown, the door drive device is designed as a device mounted resting on the door. However, it should be expressly pointed out that the door drive device 10 of this construction can also be designed as a door drive device to be installed concealed on the inside of the door.

The main drive:

As the figures show, the sliding arm door closer forming the main drive 1 comprises a drive unit 1g, which is designed as a door closer unit accommodated in a door closer housing 1g, and a power transmission device 1k. The force introduction device 1k consists of a linkage, which is designed as a slide arm 1ka, and a linkage bearing, which is designed as a slide rail 1ks. This force transmission device 1k constructed in this way is also referred to in practice as a force-transmitting slide rail linkage. In the case shown, the door closer housing 1g is mounted on the door leaf 3f. The closer mechanism is accommodated in the door closer housing 1g. It is not shown in more detail in the figures. As is conventional, it can comprise a closing spring device and a damping device. The damping device is preferably designed as a hydraulic damping device. The closing speed and the opening speed of the door can be adjusted via the damping device, preferably via flow valves. The closer spring device and the damping device are operatively connected to a door closer shaft 1w. The door closer shaft 1 is rotatably mounted in the door closer housing 1g. The sliding arm 1ka of the linkage 1k is connected to the end of the door closer shaft 1w protruding from the housing. In the case shown, this consists of the slide arm 1ka and the slide rail 1ks. The sliding arm 1ka is a one-armed lever which is non-rotatably connected to the door closer shaft 1w with its end facing the output of the drive unit 1g. This end of the sliding arm 1ka forms the connection end. With its other end, the slide arm 1ka is guided in the slide rail 1ks via a slide 1kag engaging in the guideway of the rail. The slide rail 1ks is mounted horizontally aligned on the upper horizontal beam of the stationary door frame 3r fixed to the door frame. In the case shown, the sliding arm door closer 1 is designed, as already mentioned, as an overlying sliding arm door closer, i.e. the door closer housing 1g and the slide rail 1ks are each mounted overlying. In the case shown, the door closer housing 1g is mounted in the upper area of the door leaf resting on the door leaf 3f and the slide rail 1ks resting on the upper horizontal beam of the door frame 1r.

The auxiliary drive

In the case shown, the auxiliary drive 2 is designed as a door pull with damping. It is a drive unit that is designed separately from the sliding arm door closer 1 that forms the main drive 1 . As a drive unit 2g, it comprises a damped closing unit that is mounted on the door leaf 3f, and that is remote from the door axis relative to the main drive 1, i.e. further away from the door axis than the door closer housing 1g of the main drive 1, namely at a distance next to the door closer housing 1g in the upper Mounted area of the door leaf. As stated, the closing unit 2g forms the drive unit of the auxiliary drive 2. The unit 2g is designed as a spring accumulator with a hydraulic damping device. In the case shown, it comprises a piston-cylinder unit 2gkz, which interacts with a closer spring device 2gf. Let it be 2.3 and 2.4 and on the 3.3 and 3.4 referred. The piston-cylinder unit 2gkz shown can be designed as a hydraulic damping device. Instead of the illustrated piston-cylinder unit 2gkz with closing spring 2gf, however, a gas pressure spring can also be provided. In the case shown, the cylinder 2gz of the piston-cylinder unit is mounted pivotably on the door leaf 3f in a pivot bearing 2gs which is fixedly mounted on the door leaf and has a vertical pivot axis in the installed position. The piston 2gk is linearly displaceable in the cylinder. The piston 2gk is designed as a piston rod 2gks in the area of its free end section. The free end of the piston rod 2gks forms the output end of the piston rod and thus the output end of the drive unit 2g of the auxiliary drive 2.

In the case shown, the power transmission device 2k of the auxiliary drive 2 is designed as a slide rail linkage, which is composed of an angle arm 2ka as the slide arm and a slide rail 2ks as the linkage bearing. The angle arm 2ka is designed as a sliding arm that can be coupled/disengaged relative to the sliding rail. The angle lever 2ka is connected to the output end of the piston rod 2gks of the auxiliary drive 2 via a connecting joint 2gg. The joint axis of the connecting joint 2gg is vertical in the installed position, ie aligned parallel to the pivot axis of the pivot bearing 2gs, via which the drive assembly 2g of the auxiliary drive 2 is mounted on the door leaf. In the case shown, the angle lever 2ka is designed as a right angle. The connecting joint 2gg to the driven end of the piston rod 2gks acts on the outer vertex of the angle lever 2ka. The angle lever 2ka has a shorter leg 2kab and a longer leg 2kaa. At the free end of the shorter leg, the angle lever 2ka is pivotably mounted in a pivot bearing 2kas with a vertical pivot axis. The pivot bearing 2kas is fixed to the wing in the same way as the pivot bearing 2gs of the cylinder 2gz. Both camps 2kas and 2gs are mounted in a rigid mutual association in a bearing frame 2m fixed to the wing. The swivel bearing 2kas forms a stationary output bearing with the drive unit. The connection of the angle arm 2ka in the area of its corner apex corner 2kae at the output end of the piston rod 2gks, forming the connecting joint 2gg, forms the connection of the angle lever 2ka at the output end of the drive unit 2g.

The free end of the long leg 2kaa of the angle lever 2ka is designed as a slider 2kag and can be automatically engaged and disengaged in the slide rail 2ks of the door puller 2 mounted on the frame side. In the coupled position in the slide rail 2ks, the angle lever 2ka forms a force-transmitting linkage with the slide rail 2ks as a special sliding arm linkage with slide rail. The automatic coupling and decoupling takes place when the door leaf reaches a predetermined door opening angle. In the exemplary embodiment shown, this predetermined door opening angle is approximately 30° door opening angle. During the opening and closing process in the area of the door opening angle between 30° and 0°, i.e. in the partial opening area between a door opening of 30° and the closed position of the door, the angle lever 2ka is guided as a force-transmitting sliding arm with its slider 2kag engaging in the sliding rail 2ks.

As best illustrated in the 2.3 and 2.4 as well as the 3.3 and 3.4 recognizable, the pivoted piston-cylinder unit 2gkz with its piston rod 2gks forms a toggle lever together with the likewise pivoted angle lever 2ka in connection with the articulated connection in 2gg. The connecting joint 2gg forms the knee joint. Due to this knee joint configuration, the angle lever 2ka can assume two dead center positions. One dead center position is the on / off clutch position in the 3.3 and 3.4 is shown. In this position, the pivot points of the bearings 2gs, 2kas, 2gg are in a line. The other dead center position of the angle lever 2ka is the closed end position, in which the angle lever is coupled in the slide rail 2ks and its in the 1 right end position, in which the door is closed. This dead center is in the 2.3 and 2.4 shown. In this position, the pivot points of the bearings 2gs, 2gg, 2kag are in a line. The hinge point 2kag is formed by the slider of the sliding arm 2ka, which engages in the slide rail 2ks in this position. In both dead center positions, the slide arm 2ka is constantly locked in the associated angular position and the output of the connected drive unit 2g is thus also correspondingly fixed.

In the first dead center position, i.e. in the engaged/disengaged position of the slide arm 2ka, the closing spring 2gf of the piston-cylinder unit 2gkz is more tensioned than in the second dead center position, i.e. in the end position associated with the closed position of the door. Due to the first dead center position of the sliding arm 2ka, the tension of the closer spring, i.e. the charging that the closer spring assumes in the engaged/disengaged position, is maintained in the disengaged position.

As soon as the slide arm 2ka is engaged in the slide rail 2ks, the first dead center position is automatically released during the closing process, specifically by changing the angular position of the slide arm. The sliding arm 2ka is driven in the closing direction by the action of the closing spring 2gf, with the prestressing of the closing spring 2gf being relieved. The slide arm 2ga rotates in 3.2 clockwise and runs in the slide rail 2ks in 1 To the right. During the opening process, the movement of the sliding arm 2ka is exactly the opposite. In a corresponding manner, the closing spring 2gf is charged during the opening movement of the door as long as the slide arm 2ga is coupled in the slide rail 2ks.

What is essential in the illustrated embodiment is that the sliding arm door closer 1 is arranged closer to the door axis, i.e. closer to the door hinges, than the auxiliary drive 2. The sliding arm 1ka of the sliding arm door closer 1 remains permanently coupled to the slide rail 1ks and guided therein during the entire opening and closing process . The slide at the free end of the slide arm 1ka runs in the slide rail 1ks when closing 1 to the right and when opening in 1 to the left. In contrast to this, the force-transmitting linkage 2k of the auxiliary drive 2 is, as already explained above, designed such that the slide arm 2ka with the slide rail 2ks can be automatically engaged and disengaged at a predetermined door opening angle during the closing and opening process. The engagement and disengagement takes place in such a way that the free end of the angle lever acting as a slide arm 2ka is coupled to the slide rail 2ks exclusively at door opening angles in the range between this predetermined door opening angle and the closed position, i.e. it engages in the slide rail in this door opening angle range and during the closing process and is guided in the slide rail 1ks only in this angular range during the opening process. In the area of larger door opening angles, ie from the predetermined door opening angle, the free end of the sliding arm 2ka is disengaged from the sliding rail 2ks, ie not connected to the sliding rail and not guided in the sliding rail.

For coupling and decoupling of the slider 2kag formed at the free end of the sliding arm 2ka, the sliding rail 2ks has an opening 2kö at the front. This opening opens out via a run-in slope into a slideway within the slide rail 2ks, in which the slide 2kag after the coupling during the closing movement and the reverse movement movement is guided in the opening direction. Depending on the design variant of the auxiliary drive 2, this slideway in the horizontally mounted slide rail 2ks can be linear or non-linear. As discussed, the sliding arm 2ks is engaged and disengaged automatically during the opening and closing process.

How the drive mechanism works:

The operation of the door closer device 10 composed of the sliding arm door closer 1 and the auxiliary drive 2 is as follows:

from the inside 1 shown closed position of the door, the door 3 can be opened by manually pivoting the door leaf 3f in the opening direction. Here, the door closer sliding arm 1ka rotates with the door closer shaft 1w, which is connected in a rotationally fixed manner, about the axis of rotation of the door closer shaft 1wim 1 counterclockwise. The sliding arm 1ka is guided with its free end designed as a slider in the sliding rail 1ks in such a way that the free end of the sliding arm 1ka is shown in FIG 1 runs to the left.

During this opening movement, the toggle-lever-like sliding arm 2ka of the auxiliary drive 2 also rotates in a corresponding manner, in that the free end of the sliding arm 2ka runs to the left with its free end in the slide rail 2ks in the illustration in the figures. The toggle-lever-like sliding arm linkage, which consists of the angle arm 2ka and the piston rod 2gks of the piston-cylinder unit 2gkz, rotates in a corresponding manner around the axis of the pivot bearing 2gs fixed to the wing. What is essential in the illustrated embodiment, however, is that this toggle-lever-like linkage, i.e. the free end of the angle sliding arm 2ka, automatically disengages from the slide rail 2ks as soon as the door opening angle predetermined for this purpose is reached from the closed position. In the exemplary embodiment shown, this takes place at a door opening angle of approximately 30°. In this angular position, the toggle-lever-like linkage 2k reaches its first dead center position. When decoupling from the slide rail 2ks, the angle arm 2ka remains in the angular position of this dead center position. In this position, the angle arm is virtually locked against further rotation and, in this angle position, moves out of the front opening 2kö of the slide rail 2ks as the door is opened further. In the dead center position, the angle arm 2ka remains more or less locked. The piston rod of the piston-cylinder device with the closing spring also remains locked in this position.

When the door is to be moved from the open position to the closed position again, the closing movement takes place with the angle arm 2ka disengaged up to the predetermined angle of engagement. The angle arm 2ka is therefore unchanged in the dead center position 3.1 and 3.4 , which she took when disengaging. As soon as the door leaf has reached the predetermined door opening angle of approx. 30° during the closing process, the free end, ie the slider 2kag, of the angled arm 2ka fixed in this coupling/decoupling angular position is again coupled into the slide rail 2ks. The free end of the slide arm 2ka with the slide 2kag moves into the opening of the slide rail 2ks. When the door is closed further, the angle arm 2ka is coupled with its free end in the slide rail 2ks and runs in the illustration 1 in the slideway of the slide rail 2ks to the right through the slide rail 2ks. In this case, the toggle lever configuration has automatically released the engaged/disengaged locking position under the action of the slide rail guide by changing the angular position of the free end of the angle arm 2ka. As soon as this dead center position is released, the closer spring, which has been held under tension until then, now acts under discharge as a rotary drive of the angle lever in the closing direction. This means that the closing process is then supported by the auxiliary drive 2. The toggle lever finally reaches its in position when the door is in the closed position 1 illustrated second dead center position. In this second dead center position, the toggle lever configuration locks in the relevant angular position. This dead center position then remains upright until the door is pivoted back into the open position by manually opening the door leaf. During this opening movement, the pivoting of the angle arm 2ka automatically cancels the dead center position and the closing spring is recharged.

Modified auxiliary drive

In the 4.1 until 4.3 an auxiliary drive 2 is shown, which, like in the exemplary embodiment of the preceding figures, has a drive unit 2g with a piston rod 2gks, for example designed as a gas pressure spring. The difference from the exemplary embodiments of the preceding figures is that the drive unit 2g is used when pressure is applied, ie the piston rod 2gks is pushed into the housing, ie into the piston, ie shortened, when the door is opened while charging the energy store. When the door is closed, the piston rod is pushed out, ie lengthened, while discharging the energy store. For this purpose, the mounting of the drive unit 2g is modified accordingly compared to the exemplary embodiment in the preceding figures. In case of 4.1 until 4.3 acts the piston rod 2gks on a bearing frame mounted link device with a connecting link 2kav, which is connected at one end to the piston rod 2gks and engages at its other end on the angle arm 2ka and the Publ The door is subjected to tension when the piston rod is extended 2gks.

How from the 4.1 until 4.3 recognizable, the drive unit 2g of the auxiliary drive 2 is mounted on a bearing frame 2m, which is to be mounted fixed to the wing in the same way as in the previously described exemplary embodiment when the drive unit 2g is mounted on the wing side. The drive assembly 2g is articulated with its cylinder-like housing in a pivot bearing 2kas arranged on the bearing frame 2m. The output end of the piston rod 2gks is articulated on a bearing link 2gkv. The bearing link 2gkv is supported at its bearing end in a pivot bearing 2gs arranged on the bearing frame 2m. At its free end, the bearing link 2gkv has a spherical bearing 2gkg for the articulated support of the piston rod 2gks. The slide arm 2ka is also designed as an angle arm in this exemplary embodiment, in the case shown also as a right angle with a first and a second leg. The first leg 2kaa is, as in 4.1 recognizable, offset in height compared to the second leg 2kab. For this purpose, the first leg 2kaa has a height offset piece 2kah at the apex end, so that the first leg 2kaa is essentially L-shaped and protrudes vertically from the apex end of the second leg 2kab.

The slider 2kag is arranged at the free end of the first leg 2kaa. The second leg 2kab is designed as a bearing leg, which is mounted with its free end in the pivot bearing 2kas arranged on the storage frame 2m. The housing of the drive unit 2g is also mounted in the same rotary bearing 2kas. The connecting link 2kav connects the joint bearing 2gkg, in which the output-side end of the piston rod 2gks is supported, with the bearing 2kas arranged in the apex of the angle arm 2ka, in which the connecting link 2kav has one end in the joint bearing 2gkg and the other end in the Crown bearing 2kas is articulated.

The height offset of the angle arm 2ka, ie the height offset of the lever arms 2kaa and 2kab to each other is in the in 5.1 and 5.2 illustrated embodiment adjustable. This embodiment corresponds in structure and function to the embodiment of FIG 4.1 until 4.3 . The adjustability of the height offset takes place, as from the 5.1 and 5.2 shows, via a slotted screw connection 2kj of the two arms 2kaa and 2kab. In the embodiment shown, two oblong holes are formed in the vertical offset piece 2kah of the first arm 2kaa, in which are engaged fastening screws fixed in fastening holes of the second arm 2kab, for example by means of a screwing with nuts. They form a clamping connection of the two arms 2kaa and 2kab, which can be adjusted in terms of height, in order to adjust the height offset to match the height position of the drive unit 2g relative to the slide rail 2ks.

Modified drive with assembly space M

The embodiment of 6.1 until 6.3 shows a modification of the embodiment of the drive of the previous figures. The modification is also a compound drive from a main drive 1 and an auxiliary drive 2. The modification consists in that the slide rail 2ks of the auxiliary drive 2 is arranged in a plane on the front side of the slide rail 1ks of the main drive 1, i.e. the slideway of the slider 2kag of the auxiliary drive 2 is in a plane which lies at the front in front of the slideway of the slider 1kag of the main drive 1. As in the 6.1 until 6.3 can be seen, the slideway of the slider 2kag of the auxiliary drive 2 can overlap with the slideway of the slider 1kag of the main drive 1 to a greater or lesser extent. However, it is essential that the two slideways are offset parallel to one another towards the front side and thus do not impede one another. This offset to one another has the advantage that any additional components of the main drive 1, which are arranged in the slide rail of the drive in conventional sliding arm drives, such as a locking device in the open position of the door, a smoke detector or, in the case of double-leaf doors, closing sequence control components, continue to be accommodated in a conventional manner in one Mounting space can be arranged, which is in the slide rail 1ks or in an extension line of the slideway of the slider 1kag this slide rail, since the slide rail 2ks of the auxiliary drive 2 is arranged outside of this mounting space, ie leaves this mounting space free.

Drive with manipulation protection for the disengaged sliding arm of the auxiliary drive

In the 7.1 until 7.7 an embodiment of a manipulation protection device 5 is shown, which is used to fix the predetermined position of the disengaged force transmission arm of an auxiliary drive in an open position of the door leaf and thus to protect against manipulation. In the embodiment of 7.1 until 7.7 such a manipulation protection device for the angle arm 2ka of the auxiliary drive 2 is provided. The structure of the overall drive is the same as in the 6.1 until 6.3 shown. The anti-tamper device 5 in the 7.1 until 7.7 comprises a lever device with a control arm 5ka designed as a pressure arm and a blocking arm 5ks. The two arms are movably mounted on a guide and bearing plate 5f in the manner of swivel arms. The plate 5f is arranged on the bearing frame 2m of the auxiliary drive 2 on the wing side. The bearing frame 2m is connected on one side to the underside of the guide and bearing plate 5f. The guide and bearing plate 5f is perpendicular to the front of the storage rack 2m. In the upper free area of the guide and bearing plate 5f opposite to the direction of the door opening there is a fixed pivot bearing 5kal. The control arm 5ka is pivotably mounted in this bearing 5kal. The control arm 5ka is connected to the pivot bearing 5kal in a region between the two ends of the control arm 5ka relatively close to the end of the control arm 5ka facing away from the door leaf 1 . This end of the control arm 5ka facing away from the door leaf 1 has a pivot bearing 5ks1, via which this end of the control arm 5ka is pivotally connected to one end of the blocking arm 5ks, which is guided in the direction of the door opening, by means of a further axis. The blocking arm 5ks is guided between a lower guide 5fu and an upper guide 5fo, which are located on the front side in the direction of the door opening on the guide and bearing plate 5f. The upper guide 5fo is located at the upper edge of the guide plate 5f, which points away from the door leaf 1. The blocking arm 5ks is guided between the lower guide 5fu on the guide and bearing plate 5f and the upper guide 5fo in such a way that when the door leaf 1 is in the open position, the free end of the blocking arm 5ks pointing in the direction of the door opening comes into contact with the disengaged angle arm 2ka . In the illustrated embodiment, the stop position of the free end of the locking arm 5ks occurs with the vertical offset piece 2kah of the arm 2kaa of the guide arm 2ka, ie in the region of the axis of the apex of the arms 2kaa and 2kab. For this purpose, the free end of the blocking arm 5ks has a locking recess 5snr on the face side, which is designed in such a way that it is approximately complementary to the stop edge of the offset piece 2kah of the guide arm 2ka. This effectively prevents the position of the guide arm 2ka from changing when the door leaf 1 is in the open position.

So that the blocking arm 5ks remains in this position to secure the predetermined position of the angle arm 2ka when the door leaf 1 is in an open position, the control arm 5ka of the anti-tamper device is connected to one end of a return spring 5r between its free end pointing towards the door leaf 1 and the pivot bearing 5kal. The other end of the return spring 5r is connected to the guide and bearing plate 5f opposite to the door opening direction. The restoring spring 5r holds the control arm 5ka against a stop 5fa located on the guide and bearing plate 5f in the opposite direction to the door opening. The free end of the control arm 5ka is connected to a slider 5kag designed as a roller.

A vertical offset piece 5kav is located in the joint bearing 5ksl between the control arm 5ka and the blocking arm 5ks, standing perpendicularly on both arms. The offset piece 5kav is used to position the control arm 5ka with the slider 5kag at the level of the slider arm 1ka of the main drive 1, so that the slider 5kag can be caught by the slider arm 1ka of the main drive 1 during a closing process of the door leaf 1 in order to actuate the control arm 5ka.

During a closing process of the door leaf 1, the sliding arm 1ka of the main drive 1 exerts pressure on the slider 5kag of the anti-tamper device 5 when the slider 5kag is placed on the sliding arm 1ka, and the control arm 5ka is thus moved in the direction of the door opening. The control arm 5ka then pulls the locking arm 5ks via the joint bearing 5ksl in the opposite direction to the door opening and thus releases the guide arm 2ka of the auxiliary drive 2, so that the guide arm 2ka couples with the slider 2kag in the slide rail 2ks and the auxiliary drive 2 can become effective. The angle between the scissor-like control arm 5ka and blocking arm 5ks connected in the joint bearing 5ksl is always less than 90° when the door leaf 1 is in the open position and closed position, in order to ensure smooth actuation of the blocking arm 5ks.

During the opening process of the door leaf 1, the control arm 5ka is reset by the return spring 5r pulling the control arm 5ka back to the stop 5fa, so that the blocking arm 5ks moves in the direction of the door opening and finally the locking recess 5snr on the free end of the blocking arm 5ks on the complementary Stop edge on the set piece 2kav of the guide arm 2ka of the auxiliary drive 2 comes into contact again. The anti-tamper device 5 is thus effective again after the door leaf 1 has been opened and the disengaged angle arm 2ka is held in its angular position.

The dead center device T of the toggle lever configuration K of the guide arm 2ka forms a first holding device for the disengaged guide arm 2ka. The tamper protection device 5 with the lever device consisting of the locking lever 5ks and the control lever 5ka forms a second holding device for the disengaged guide arm 2ka of the auxiliary drive 2. The two retaining devices form a combined overall holding device which holds the disengaged guide arm in the ready position. Only when both holding devices are released in the sense of switching off the respective holding device is the disengaged one in the ready position released Guide arm 2ka for guiding in the slide rail 2ks. The second holding device, ie the locking lever 5ks, is released by actuating the control lever 5ka by striking the sliding arm 1ka of the main drive 1 when the predetermined door angle position is reached. The first holding device is released by actuating the free end of the guide arm 2ka, ie by pivoting the free end out of its angular position. This takes place as intended when the slide 2kag enters the opening 2kö of the slide rail 2ks. Only when both holding devices are actuated simultaneously or within a predetermined period of time in the sense of release is the entire holding device released and thus the disengaged guide arm 2ka released.

In the illustrated embodiment, the required switching sequence is such that the locking lever 5ks must first be released and then or at least simultaneously the dead center position device T of the toggle lever configuration K must be released by actuating the free end of the disengaged angle arm 2ka. The release devices of the assembled holding device are arranged in such a way that they are not easily accessible from the outside for improper manipulation. This is done on the one hand by a cover panel and on the other hand by the fact that the various components of the drive are arranged in a nested manner, making improper access more difficult. The cover panel can be designed in such a way that it covers the respective release device separately, but in the case shown the cover panel is designed as a common cover panel which covers at least all components of the auxiliary drive 2 mounted on the wing side or in particular as a common cover panel for the components of the auxiliary drive 2 on the wing side and the main drive 1, as preferably hood-shaped cover 3fh to the embodiment of 1 until 4 is described in more detail.

In the 8.1 until 8.3 a second exemplary embodiment of a manipulation protection device 5 is shown. In this case, the anti-tamper device also serves to fix the disengaged power transmission arm 2ka of the auxiliary drive 2. In the exemplary embodiment shown, the auxiliary drive is an auxiliary drive of the structure, as is shown in FIGS 4.1 until 4.3 is shown and therefore also in the drive 7.1 until 7.7 is provided. In order to fix the predetermined position of the disengaged angle arm 2ka in the open position of the door leaf 1, the manipulation protection device 5 is in the 8.1 until 8.3 a first permanent magnet 81 is fastened to the bearing frame 2m of the auxiliary drive 2, which is to be fixed to the wing, on the end face on the right in the figures, facing in the direction of the door opening. Furthermore, a second permanent magnet 82 is attached to the surface of the vertical displacement piece 2kah of the angle arm 2ka, which faces the end face of the storage frame 2m. The first permanent magnet 81 and the second permanent magnet 82 are positioned relative to one another in such a way that the first permanent magnet 81 is arranged in the plane of movement of the permanent magnet 82 . The magnetic poles of the two permanent magnets 81 and 82 are formed so as to attract each other when the angle arm 2ka with its permanent magnet 82 is placed at a predetermined position close to the permanent magnet 81 mounted on the bearing frame 2m. In 8.2 the relevant position is shown in which the attractive effect exists.

When the door leaf 1 is in the open position, the disengaged angle arm 2ka is positioned with the slider 2kag such that when the door leaf 1 is closed, the slider 2kag always engages in the opening of the guideway of the guide rail 2ks. In this position, the angle arm 2ka is in its disengaged dead center position due to its toggle lever configuration. The angle arm 2ka is additionally fixed by the magnetic force of attraction of the two permanent magnets 81 and 82 . The dead center device T of the toggle lever configuration K of the guide arm 2ka forms a first holding device. The magnetically acting device with the magnets 81 and 82 forms a second holding device of the guide arm 2ka in its uncoupled position.

The angle arm 2ka is released automatically during the closing process as follows: During the closing process of the door leaf at a predetermined door opening angle shortly before the door closes, the slider 2kag of the angle arm 2ka engages in the opening 2kö of the guide track of the guide rail 2ks. The angle arm 2ka overcomes the dead center of the angle arm designed as a toggle lever and at the same time separates the first permanent magnet 81 from the second permanent magnet 82 and continues to move over the slider 2kag in the guideway of the slide rail 2ks. The magnetic lock of the angle arm is switched on automatically when the coupling is disengaged, as follows: During the opening process of the door leaf from the closed position of the door, the pivoting movement of the angle arm 2ka causes the permanent magnet 82 arranged on the angle arm to approach the permanent magnet 81 fixed to the bearing frame. Immediately after disengagement of the angle arm 2ka from the slide rail 2ks, the contact of the permanent magnets 81 and 82 then takes place and due to the knees Lever configuration of the guide arm 2ka takes place through the formation of its dead center position.

Exemplary embodiments are possible in which the sliding arm 2ka of the auxiliary drive 2 is not designed as an arm that forms a toggle lever configuration with a dead center, but is held exclusively by a magnetic device in the predetermined angular position when the sliding arm is disengaged, or by the magnetic device and, in addition, another holding device , For example, a lever device with control lever 5ka and locking lever 5ks, as in the 7.7 until 7.7 is shown.

There are also compared to the embodiment in the 8.1 until 8.3 modified magnetic devices possible, in contrast to the magnetic device 8.1 until 8.3 have an electromagnet as a magnetic element 81 or 82, which interacts with a ferromagnetic or permanent-magnetic counter-element 82 or 81, respectively.

Versions with electromagnets are particularly suitable for applications in which the electromagnetic element is to be mounted on the frame side, i.e. preferably in versions in which the decoupled guide arm to be fixed with the holding device is mounted on the frame side.

At the in the 9a-9c and 10 The second exemplary embodiment shown is in each case a door drive composed of a main drive 1 and an auxiliary drive 2.

The main drive of the second embodiment:

In the case shown, the main drive 1 is a slide arm door closer with a drive unit 1a mounted on the leaf F and a power transmission device 1k as a slide rail linkage with a slide arm 1ka and a slide rail 1ks. The slide arm 1ka is coupled in a torque-proof manner to an output shaft 1w mounted in a housing of the drive unit 1g and guided on the slide rail 1ks fixed to the frame. In the exemplary embodiment shown, the main drive should be in the form of a sliding arm door closer with a drive unit 1g with a closer spring and hydraulic damping device.

The auxiliary drive of the second embodiment:

In the case shown, the auxiliary drive 2 is formed from a drive assembly 2g and a force-transmitting linkage 2k. The drive unit 2g is integrated in a slide rail 2ss and fixed in a fixed position. The slide rail 2ss connects to the slide rail 1ks of the main drive 1. In the case shown, the two rails 1ks and 2ss are designed as sections of a common, continuous slide rail. The drive unit 2g of the auxiliary drive integrated in the section 2ks of the slide rail comprises a spring accumulator 2f or, alternatively or additionally, an electric motor. The output 2aa of the spring-loaded motor 2f or the electric motor interacts with the slider 2kag guided in the slide rail 2ks. This is a slide at the free end of the slide arm 2ka. The sliding arm 2ka is pivoted with its bearing end in a pivot bearing 2kd mounted on the wing side and guided with its free end via the slider 2kag in the slide rail 2ss. The slider 2kag is connected to the free end of the output 2aa of the drive unit 2g integrated in the slide rail 2ss. The output 2aa is guided in the slide rail 2ss so that it can be moved linearly along the guideway of the rail. The glider 2kag is taken along. The slide rail 2ss forms a stationary output bearing with the drive unit 2g.

The output 2aa is guided in the guideway of the slide rail and is therefore a linear output. In the illustrated embodiment, the track of the slide rail is linear and extends horizontally. It should be pointed out that the output 2aa is also understood as a linear output if, in a modified embodiment, the guideway of the slide rail is designed as a non-linear cam track. It should also be pointed out that further modified versions are also understood as linear output, namely in which a gear is connected between the primary output of the drive unit and the output 2aa guided in the guideway of the slide rail. The primary output can be designed as a rotary output, for example. It can be designed as a rotating threaded spindle on which a threaded nut runs, which is linearly guided in the guideway and drives the slide arm 2ka, e.g. by driving the slide 2kag.

How from the 9b and 9c recognizable, the slide arm 2ka of the auxiliary drive 2 can be engaged and disengaged with the drive assembly 2g in the slide rail 2ks.

The coupling / decoupling point is in the embodiment 9b , 9c formed between the free end of the slide arm 2ka and the guided in the slide rail 2ss output member 2aa of the mounted in the slide rail 2ss drive unit 2g, ie between the connection end of the slide arm 2ka and the output of the drive unit 2g.

The coupling and decoupling takes place automatically during the opening and closing process at a specific door opening angle. the 9b shows the door position in the door opening angle in which the clutch is engaged during the closing process and the clutch is disengaged during the opening process. With door opening angles smaller than this decoupling and coupling angle position, the sliding arm 2ka is coupled (see 9b and 9a ). If the door opening angle is greater than the engagement/disengagement angle position, the slide arm is disengaged (see 9c ).

In the disengaged position, the sliding arm 2ka remains on the linkage bearing in this exemplary embodiment, ie in the illustrated case 9c on the wing-side pivot bearing 2d, in a locked angular position projecting from the wing F. The angular position can be locked by a latching device which interacts with the sliding arm. The locking device is formed in the pivot bearing 2kd. The locked angular position corresponds to the angular position that the sliding arm 2ka assumes when coupling/disengaging, ie the angular position in 9b . While the sliding arm 2ka is disengaged, the spring accumulator 2f of the drive assembly 2g remains in the charged position in which it was disengaged. This is the charged position that the spring accumulator has reached during the opening process with the sliding arm coupled. A locking device is provided in the area of the drive unit 2g for this locking of the spring accumulator. It is switched on when the sliding arm 2ka is uncoupled and switched off by releasing the spring accumulator when the sliding arm 2ka is engaged.

The coupling process between the free end of the slide arm 2ka and the slide 2kg guided in the slide rail 2ks takes place automatically when the door is closed at the predetermined door opening angle, which is 9b is shown. The free end of the sliding arm 2ka protruding in this angular position moves with its slider 2kag in this door opening position into the sliding rail 2ks, namely via an inlet slope, not shown in detail, through a front opening of the sliding rail 2ks and couples with the waiting position therein designed as a slider Output member 2aa. With the coupling, the spring accumulator 2f, which is arranged in the slide rail and was charged during the previous opening process, is forcibly released. By discharging the spring accumulator 2f in this way, the slide 2aa together with the slide 2kag and slide arm 2ka coupled thereto are driven in the closing direction. The coupled sliders 2kag and 2aa are moved to the right as viewed in the figures, and the slider arm 2ka is rotated clockwise about the pivot bearing 1kd. This means that the door leaf F is moved in the closing direction. It finally reaches the closed position that 1a is shown. In the closed position, the sliding arm again reaches a detent position in which it remains until the door is then opened again to allow access. This is done manually by pivoting the door leaf F in the opening direction.

During the opening movement of the door leaf, the slide arm 2ka is rotated counterclockwise about the pivot bearing 1kd in the representation in the figures. The slider 2kag with the output slider 2aa is thereby moved in the opening direction, ie moved to the left in the slide rail in the illustration in the figures. As soon as the door leaf has reached the predetermined door opening angle of coupling and decoupling, which is 9b is reached, the decoupling of the sliding arm 2ka takes place automatically. The decoupled sliding arm 2ka then remains fixed in the predetermined angular position which it assumes when decoupling, protruding from the pivot bearing 1kd on the wing side.

After the sliding arm 2ka has been disengaged, the driven slider 2aa also remains in the position it assumed when it was disengaged, fixed by the already mentioned locking device. Because of this automatic determination, the storage spring 2f connected to the driven slider 2aa also remains in the charged state as long as the sliding arm 2ka is disengaged, which the storage spring 2f has achieved through the previous opening process with the sliding arm 2ka engaged.

The auxiliary drive 2 is thus charged during the opening process as long as the slide arm 2ka is engaged, i.e. when the door is opened in the first opening angle range. During the closing process, the auxiliary drive 2 supports the closing process by discharging the spring accumulator as soon as the sliding arm of the auxiliary drive 2 is engaged. The support takes place in the last closing phase, i.e. at the end of the closing process until the door has reached the closed position.

10 shows a modified embodiment that differs from the embodiment of FIG 9a-9b differs in that the coupling/decoupling point of the sliding arm 2ka is not formed between the output of the drive unit 2g and the connection end of the sliding arm 2ka, but in the area between the pivot bearing 1kd fixed to the wing and the sliding arm 2ka in the area of the bearing end of the sliding arm. In this modified embodiment, too, the sliding arm 2ka remains in the angular position it assumed when it was uncoupled, as long as it is uncoupled. Here, too, there is a locking device for the angular position of the disengaged sliding arm and a locking device for the rest tion of the storage spring 2f provided. This determination can be made by locking the sliding arm 2ka in the predetermined angular position in the manner of a dead center position, ie in a similar manner to the exemplary embodiment in FIG 1 until 4 . This means that in this exemplary embodiment too, the storage spring 2f remains in the charged position which it had when the slide arm 2ka was disengaged.

It is essential in the in the 9 and 10 illustrated embodiments that the frame-side mounted components of the main drive 1 and the auxiliary drive 2, ie the slide rail 1ks of the main drive 1 and the slide rail 2ss with the storage spring 2f mounted therein are covered by a common continuous frame-side cover 3rh. The same applies to the wing-side components, ie the drive housing 1g of the main drive 1 and the pivot bearing 2kd of the force-transmitting linkage of the auxiliary drive 2. They are covered by a common, continuous cover 3fk (not shown in the figures).

The common continuous wing-side mounting plate 3fm, on which the drive unit 1g of the main drive 1 and the pivot bearing 2kd of the auxiliary drive 2 are mounted, is particularly advantageous. This mounting plate 3fm is only screwed to the door leaf in its section near the hinge in a standard hole pattern of the door leaf.

A common continuous frame-side mounting plate 3rm can also be provided for the assembly of the frame-side components.

Also with these in the 9 and 10 In the exemplary embodiments illustrated, an electrically switchable tumbler 4 with a frame-side component 4r and a sash-side component 4f can be provided. The frame-side component can be mounted in the common frame-side continuous slide rail. The wing-side component 4f can be mounted on the wing adjacent to the pivot bearing 2kd, preferably on the common wing-side mounting plate on which the pivot bearing 2kd and the drive unit 1g of the main drive are also mounted.

In a modification of the embodiment in 10 the drive unit can also be arranged on the sliding arm 2ka or integrated therein. At the free end of the slide arm 2ka, a pinion driven by the drive unit 2g can be arranged, which is guided in the slide rail 2ss, for example meshing with a toothed rack arranged in the slide rail 2ks.

Also in the embodiments of 9 and 10 and the modifications discussed, the use of manipulation protection devices with a corresponding holding device is possible. It can be used here, the tamper protection device and the holding device, the above in connection with the 7.1 until 7.7 and 8.1 until 8.3 are described.
