Description

They are eg from the DE 37 42 213 A1 Manual door drives are known, which have a drive unit with a power transmission device and are designed for mounting on doors with swing door. Depending on local conditions and application, the drive unit is mounted on the wing side or on the frame side. The power transmission device is supported on the opposite side, ie on the frame side or wing side. The drive unit comprises in this known manual door drive a closing spring unit and a hydraulic damping device. The closing spring unit and the hydraulic damping device are accommodated in a housing in which the output shaft is also mounted, to which the power transmission device is connected. This can be carried out in practice as a scissor linkage or Gleitarm slide rail device.

An electromechanical door drive, which is comparably formed from a drive unit and a corresponding power transmission device is, for example, from EP 1 505 239 B1 known. The drive unit comprises an electric motor whose output shaft is connected to the power transmission device, which may be formed in the same manner as in the above-mentioned manual door closer as a scissor linkage or Gleitarm slide rail device. The electromechanical drive is mounted in a comparable manner on a door with swing door leaf, as described above for the manual door closer.

An essential function of the manual and electromechanical door drives is that at the end of the closing process, the door must safely enter the lock position by overcoming the lock catch. In the known manual door closers with hydraulic damping this is usually a so-called. Hydraulic end shock provided, which consists in that the hydraulic damping in the final phase during the closing process has a bypass. In practice, this often causes the door to slam shut with a loud bang when the door locks. If the end stop is set weaker, it may happen that the spring force of the closing spring at the end of the closing operation is not sufficient to close the door, i. It may happen that the door does not get into the closed position, the latch is not suppressed and the door leaves only ajar against the frame before reaching the closed position.

In the known electromotive door drives the motor opening and / or closing operation is controlled by an electrical control device. However, for the drive to function reliably and safely, constant maintenance and control adjustments are required. A failure of electrical components usually leads to the complete stoppage of the drive, so that said maintenance and inspection measures are permanently required. Furthermore, the electric drive basically requires a power connection. In practice, therefore, manual door operators are often preferred.

Furthermore, door pullers and door dampers are also known which are used on doors in buildings and can only be coupled with the door during the closing and opening process in the vicinity of the closing end position and thus act on the door only in this partial area of the closing and opening operation. These drive devices likewise have a drive unit to be mounted on the frame side or wing side with a power transmission device which, however, has a linkage which can be engaged and disengaged automatically. In the EP 2 468 998 A1 Such a drive is described with automatically engageable and disengageable linkage. Similar to a manual hydraulic door closer, the drive unit has a spring accumulator with hydraulic damping device, which interacts with a driven-side sliding arm which automatically engages or disengages in a slide rail during the closing and opening process.

The US 2,190,653 describes a conventional scissor linkage hydraulic door closer in combination with a door puller that automatically engages and disengages in a pivot bearing during the closing and opening operation as described.

The invention has for its object to make a composite drive system of a main drive and an auxiliary drive so that the drive has a compact design and provides benefits in operation on the door in terms of opening and / or closing movement.

The invention solves this problem with the subject of the main claim 1 and with the subject of the main claim. 2

It is a door drive for a door of a building with a door pivotally mounted in a fixed door frame about a vertical door axis, preferably in door hinges.

The door drive has a main drive and an auxiliary drive.

The main drive is for acting on the door leaf in terms of closing movement and / or opening movement and / or closing damping and / or or opening damping, preferably designed as a manual closing spring drive or as an electric motor door drive.

The main drive has a drive unit with an output and a power transmission device with a sliding arm and a slide rail. The sliding arm is drive-connected to the output of the drive unit. He has at its free end a slider with which the sliding arm is guided in the slide rail.

The auxiliary drive is designed to form the door leaf in the sense of closing movement and / or opening movement and / or closing damping and / or opening damping. The auxiliary drive has a drive unit with an output.

The drive unit of the main drive can be mounted on the door leaf and the slide rail on the door frame. However, the reverse mounting is also possible, i. mounted with the drive unit of the main drive on the door frame and the slide rail on the door leaf.

It is essential in the drive according to the invention according to the main claim 1 that the output of the drive unit of the main drive is designed as an output shaft and that a driver with the output shaft rotatably connected axially mounted on the output shaft, wherein the driver as a separate from the sliding arm of the main drive component is trained. The driver may preferably be designed as a driving lever or as a driving plate or Mitnehmerachsstück. Here, the driving lever can be designed as a one-armed lever or as a multi-armed lever. The drive plate may preferably be in the form of an eccentrically mounted round or out-of-round disc or e.g. also be designed as a cam. The Mitnehmerachsstück can be designed as an axle piece in the configuration of a Achsverlängerungsstücks. Essential in the different versions is the respective non-rotatable mounting of the driver on the output shaft to the bearing in the axis region of the output shaft and the configuration of the driver as a separate from the sliding arm of the main drive component. Preferably, the driver is in each case directly connected to the output shaft. Due to the above-described arrangement and mounting of the driver on the output shaft of the driver rotates with the output shaft.

It is essential that the driver cooperates with the auxiliary drive. For this purpose, it is provided that the output of the auxiliary drive with the driver via an intermediate coupling device is coupled or coupled such that the drive shaft connected to the main drive at least in an end phase of the closing operation and / or at least an initial phase of the opening operation with a torque around the Axis of the output shaft is acted upon and / or applied with a transverse force with force direction transverse to the axis of the output shaft.

This means that the auxiliary drive acts in the phase of the opening or closing movement, the output shaft of the main drive, in addition to the already taking place by the drive unit of the main drive already acting on the output shaft. By the additional action on the output shaft by the auxiliary drive thus the main drive is assisted by the auxiliary drive to obtain the desired door movement in the described phases of the closing operation and / or opening operation.

This additional action on the output shaft of the main drive takes place in the solution according to the main claim 1 by the auxiliary drive such that the output shaft receives an additional torque application about the axis of the output shaft. Thus, an additional torque is introduced into the output shaft of the main drive by the auxiliary drive, so that the closing operation or opening operation is supported by transmitting the rotational movement of the output shaft to the sliding arm. Additionally or alternatively, the application of the auxiliary drive to the output shaft can also be effected in the form of a transverse force application with a force direction transverse to the axis of the output shaft. By this application, a force is applied to the output shaft, which has a force direction which is directed directly in the direction of movement of the door leaf when opening or closing. This results from the geometric relationships of the main drive designed as Gleitarmantrieb. The output shaft to which the Gleitarmgestänge consisting of sliding arm and slide is connected, stands in Gleitarmantrieben this structure, namely in the mounted position on the door, respectively parallel to the axis of rotation of the door, so that the transverse force applied to the output shaft to the door with a direction of force in the direction the opening movement or closing movement of the door acts. This means that in the case of the transverse force is applied to the output shaft by the auxiliary drive, the support of the main drive by additional closing of the door during closing and additional pressing of the door during the opening process is supported.

Now to the inventive solution according to the main claim 2: It is essential in the drive according to the main claim 2, that the output of the drive unit of the main drive is designed as an output shaft and that a driver on the output shaft transverse forces with force direction across the Supported axis of the output shaft is supported and / or a carrier in a stationary to the drive unit of the main drive bearing forces with force direction transverse to the axis of the output shaft is supported transmitting.

Essential in this solution is that the driver is necessarily compellingly designed so that it transmits at least to some extent lateral forces. In embodiments in which the driver is supported on the output shaft, the embodiment is such that it transmits lateral forces with force direction transverse to the axis of the output shaft to the output shaft or the bearing of the output shaft in the drive unit. In embodiments in which the driver is preferably offset and preferably supported at a distance from the output shaft in a stationary to the drive unit of the main drive bearing, the configuration is such that the driver forces is formed transversely to the axis of the output shaft with force direction.

The solution according to the main claim 2 provides that the output of the drive assembly of the auxiliary drive with the driver via an intermediate coupling device is coupled or coupled such that the output shaft which supports the driver, and / or stationary with the drive unit of the main drive bearing of the driver is acted upon at least in an end phase of the closing operation and / or at least in an initial phase of the opening operation with a transverse force with force direction transverse to the axis of the output shaft of the main drive.

In the solution according to the main claim 2 is carried out by the output of the auxiliary drive in the coupled position an application of the driver such that in the embodiments in which the driver is supported on the output shaft transversely transmitted, a transverse force of the output shaft with force direction transverse to the axis of the output shaft is obtained and in Ausfürhungen in which the driver is supported on the stationary with the drive unit of the main drive bearing, a force is applied to the respective stationary bearing, even with a force direction equal to the transverse force of the output shaft, namely with a direction of force transverse to the axis the output shaft. This action on the output shaft mounted in the drive unit of the main drive and / or the bearing stationary with the drive unit constitutes a force application with a force direction directly in the direction of movement of the door leaf during opening or closing. This results from the geometric relationships of the main drive designed as Gleitarmantrieb. The mounted in the drive unit of the main drive output shaft to which the Gleitarmgestänge is connected, is in the mounted state on the door, namely parallel to the axis of rotation of the door, so that the respective application of force to the output shaft or the stationary bearing acts on the door in the direction of Opening movement or the closing movement.

In the in the 1.1 to 1.7 shown first embodiment is a door drive 10 mounted on a door. The door has a door leaf F, which is mounted about a vertical axis of rotation in door hinges B pivotally mounted in a stationary door frame R.

The door drive 10 is made up of a main drive 1 and an auxiliary drive 2 together.

The main drive 1 is designed in this specific case as a door closer, as Gleitarmtürschließer. It comprises a door closer unit with a door closer housing 1g which is mounted on the door leaf F. In the door closer housing 1g is a Türschließermechanik with closing spring and a damping device, preferably designed as a hydraulic piston-cylinder device. This door closer device in the door closer housing 1g forms the drive unit of the main drive. The output of this drive unit forms a rotatably mounted in the door closer housing door closer shaft 1w , Like in 1.2 can be seen, is at the door closer shaft 1w connected a power transmitting linkage, as a sliding arm 1ka and slide rail 1ks is trained. Like in 1.3 can be seen, is the sliding arm 1ka with a slider arranged at its free end 1kag in the slide rail 1ks guided. The slide rail 1ks is on the stationary Door frame R mounted. The sliding arm 1ka with the slide rail 1ks forms the power transmission device of the main drive 1 ,

How best in the 1.1a . 1.1b and 1.1c can be seen, is the auxiliary drive 2 including its coupling device 20k at the front of the slide rail 1ks of the main drive 1 assembled. The auxiliary drive 2 acts in the illustrated embodiment via the coupling device 20k with a driving arm 3m together, rotatably on the door closer shaft 1w is stored. The driving arm 3m is like the sliding arm 1ka with the door closer shaft 1w rotatably connected. The driving arm 3m is formed as a separate component, ie the driving arm 3m and the sliding arm 1ka are two separately formed components. The driving arm 3m is in the illustrated embodiment, as seen from the figures, designed as a one-armed lever. With its one end, it is rotationally fixed to the door closer shaft 1w connected. At its free end carries the Mitnehmerarm 3m a driving pin 3mm for engagement with the coupling device 20k , The structure and function of the coupling device 20k and the auxiliary drive 2 that the coupling device 20k will be described in more detail below.

As 1.1a shows are all the frame-side components of the main drive 1 and the auxiliary drive 2 including the coupling device 20k covered by a common filler panel. In the 1.1b and 1.1c this cover is removed. In 1.1c is also the case 2gg away. The housing 2gg forms the bearing housing of the drive unit 2g of the auxiliary drive 2 and additionally the bearing and guide housing of the coupling device 20k ,

The auxiliary drive 2 has a drive unit 2g on, in the illustrated embodiment as a gas spring 2GD with a piston rod 2gks is trained. The piston rod 2gks forms the output of the drive unit 2g of the auxiliary drive 2 , Between this output of the auxiliary drive 2 and the driving arm 3m the door closer shaft 1w is the aforementioned coupling device 20k connected. It engages the drive unit during the closing process and during the opening process 2g of the auxiliary drive 2 from the driving arm 3m automatically off and on, when the door reaches a predetermined opening angle, so that during the closing operation and the opening operation in a door angle range between the closed position and a predetermined opening angle, in the illustrated embodiment between the closed position and 10 ° door opening angle, the auxiliary drive is engaged. As long as the auxiliary drive 2 is engaged, it supports the main drive 1 by taking the closer shaft 1w subjected to an additional torque. In concrete case, the auxiliary drive 2 designed as a closer actuator. The drive unit 2g comprises a gas spring as energy storage, which is charged during the opening process and discharged during the closing process. In addition to the energy storage, a damping device is included, with which the opening and closing speed can be influenced, preferably is variably adjustable. The energy storage is during the opening process, in the phase of the opening movement in which the auxiliary drive 2 is engaged, charged and discharged during the closing process in the phase in which the auxiliary drive is engaged. The auxiliary drive acts in the engaged position, the closer shaft 1w during the closing process - by discharging the gas spring - with an additional closing force and closing delay. During the opening process - by charging the gas spring - the admission is reversed, ie in terms of opening resistance and opening loss. In disengaged position, the energy storage is locked, ie it is neither charged nor discharged, it remains in the state of charge.

About the engagement of the clutch lever 20ke with the driver 3mm acts the auxiliary drive 2 on the closer shaft 1w of the main drive 1 , The auxiliary drive 2 acts on the closer shaft 1w with an additional torque and an additional closing delay, ie in addition to that of the door closer aggregate 1g generated torque and the in the door closer unit 1g generated closing damping. The auxiliary drive 2 thus supports the main drive 1 in the engaged phase of the closing operation under the action of the unloading gas spring 2GD , In the engaged phase of the opening process, the gas spring 2GD charged.

There are compared to the embodiments in the 1 modified versions possible in which instead of Mitnehmerarms 3m differently designed drivers are used. In the 2a . 2 B and 3a . 3b Examples of such drivers are shown.

2a shows a driver 3m which is designed as a driving cam disc. The Mitnehmerockenscheibe is rotatably in the illustrated case in eccentric position with the output shaft 1w coupled. The cam cam is out of round and has an outer edge 3MF on, with a corresponding not shown coupling element of a coupling device 20k interacts. The preferably designed as a clutch lever coupling element for this purpose preferably has a role in the engaged position on the outer edge 3MF rolls off the cam cam. The outer edge 3MF can be designed as a friction surface and / or as a sliding surface.

At opposite 2a modified versions may be the modification in preferred embodiments, for example, to the effect that the outer edge of the Mitnehmerkupplungsscheibe instead of the friction and sliding surface 3MF having a correspondingly extending toothing, which in the engaged position with a counter toothing on a coupling element, not shown, of a coupling device 20k is formed, engaged and meshes with this.

2 B shows a driver 3m , which is designed as a drive plate, which has a catch recess 3mfa having. The drive plate is the same as the drive plate in 2a in eccentric position against rotation with the output shaft 1w connected. The catch recess 3mfa acts in the engaged position with a coupling element, not shown, of a coupling device 20k together, which for this purpose preferably has a driving pin or a driving roller, in the engaged position in engagement with the catching recess 3mfa stands and rolls in this, when the coupling element executes the corresponding controlled pivoting or rotating movement.

3a shows a trained as Mitnehmerachsstück driver 3m , The Mitnehmerachsstück is formed in principle in the manner of a Achsverlängerungsstücks. In the case shown, the Mitnehmerachsstück is rotationally fixed to the output shaft 1w coupled. The coupling is made by complementary spur gear teeth on the output shaft 1w and catch axle 3m , The Mitnehmerachsstück is on the spur toothing axially on the output shaft 1w mounted, ie the axis 3x the Mitnehmerachsstücks is aligned with the axis of the output shaft 1w arranged. For cooperation with a coupling element, not shown, of a coupling device 20k has the Mitnehmerachsstück at its upper free end driving surfaces 3mff on, which cooperate with complementary engagement surfaces of the preferably pivotally or rotatably controlled coupling element. The coupling element can for this purpose to the driver surfaces 3mff Have complementary engagement surfaces, preferably formed in a catching recess of the coupling element, in such a way that when engaged position, the mutually associated surfaces are in positive engagement, for example: in the type of Schraubschlüsselflächen. With appropriately controlled rotary or pivotal movement of the coupling element is a Drehbeaufschlagung the Mitnehmerachsstücks about its axis 3x and thus the introduction of a torque in the output shaft 1w ,

3b shows a driver also designed as Mitnehmerachsstück 3m , The Mitnehmerachsstück is designed according to how the Mitnehmerachsstück in 3a , but instead of the driving surfaces 3MF is a rotatably mounted drive roller 3mfr rotatably mounted on the free end of Mitnehmerachsstücks. The axis of rotation of the roll 3mfr Aligns with the axis of the output shaft 1w , The corresponding coupling element of a coupling device 20k has a mating surface which engages the roller in the engaged position 3mfr is under the introduction of shear forces on the output shaft 1w , Which are directed in the direction of the closing movement or the opening movement of the door and thus act on the door in the closing direction or opening direction. The main difference to the Mitnehmerachsstück in 3a is that in the Embodiment in 3b the door closer shaft 1w through the auxiliary drive 2 exclusively or at least primarily by transverse forces is applied, which act directly in the closing direction or opening direction of the door movement.

In the embodiment of the 3a and also in the embodiments of the remaining figures, a transverse force acting on the output shaft 1w through the auxiliary drive 2 Although also be done to a greater or lesser extent. Primary is the application in these embodiments with drivers rotatably connected to the output shaft 1w connected, at least in preferred embodiments, however, a torque application about the axis of the output shaft 1w ,

3c shows an embodiment of a door drive according to the invention with the use of a trained as Mitnehmerachsstück driver 3m on the output shaft 1w of the drive unit 1g of the main drive 1 non-rotating and transposing shear forces. The driver role 3mfr is rotatably mounted on the free end of Mitnehmerachsstücks and for cooperation with the coupling jaw 20ke intended. The pivot bearing of the drive roller 3mfr is also transferring lateral forces. If the door leaves from the in 3c shown open position a closing movement under the action of the drive unit 1g of the main drive 1 performs, comes the clutch claw 20ke the clutch 20k with its catch recess in engagement with the drive roller 3mfr , The coupling claw 20ke is the output of the auxiliary drive 2 driven and motion-controlled. It is pivoted controlled in the further closing operation, as in the previous embodiment of 1 explained in more detail. In this case, the embodiment of the 3c an admission of the driving role 3mfr with transverse forces with force direction transverse to the axis of rotation of the drive roller 3mfr , which are aligned with the axis of the output shaft 1w is trained. By the transverse forces transmitting connection of the drive roller 3mfr with the output shaft 1w in their also to some extent lateral forces transmitting output shaft bearing in the drive unit 1g thus takes place a corresponding action on the entire drive unit 1g and thus the door leaf with a force direction in the direction of the closing movement of the door leaf. Under the effect of the auxiliary drive 2 Thus, the door is closed under closing delay. This action of the auxiliary drive supports the action of the main drive, which drives the output shaft 1w applied with a torque applied by the drive mechanism of the drive unit 1g of the main drive 1 , A corresponding action by the auxiliary drive 2 in the opposite direction takes place during the opening process up to the predetermined angular position at which the coupling claw 20ke from the engagement of the driver role 3mfr disengages.

The embodiment in the 4.1 to 4.5 (in the following briefly 4 called) is a modification of the embodiment of 1.1 to 1.7 (in the following briefly 1 called). The embodiment of 4 differs from the embodiment of 1 , as follows. As far as the design of the components and their assignment is concerned, let us start by focusing primarily on the 4.4 and 4.5 directed. In the embodiment in 4 is in contrast to the embodiments described above the 1 the gas spring 2GD not pivotable on the slide rail 1ks of the main drive, but in one on the slide rail 1ks arranged fixed camp. That is the gas spring 2GD is with its housing firmly on the slide rail 1ks stored. The piston rods 2gks is in one with the slide rail 1ks fixed guide housing 20kh linear in the extension direction of the slide rail 1ks slidably guided. Between the free end of the piston rod 2gks and the clutch lever 20ke is a connecting link 20vl switched when the extension and retraction of the piston rod 2gks the pivoting movement of the clutch lever 20ke controls. The connecting link 20vl is this with its one end to the end of the piston rod 2gks and with its other end with the clutch lever 20ke each connected via a jointed bearing.

The clutch lever 20ke is in one with the slide rail 1ks stored in fixed bearing and is in the embodiment in 4 through the from the piston rod 2gks controlled connecting link 20vl controlled. The guide of the connecting link 20vl is formed such that the pivot, with which the connecting link 20vl with the end of the piston rod 2gks is connected, in a guide slot 20khs in the guide housing 20kh is guided. In the illustrated embodiment in 4 is the guide slot 20khs linear in the extension direction of the guide housing 20kh , ie also parallel to the extension direction of the slide rail 1ks , educated.

The one of the gas spring 2GD driven clutch levers 20ke has the same as in the embodiment of 1 a catch recess, with which he in the engaged position with the driver 3mm of the driving arm 3m interacts. The driving arm 3m is the same as in the embodiment of 1 directly with the closer shaft 1w rotatably connected. The closer shaft 1w is thus the same as in the embodiment in 1 from the driving arm 3m directly by the action of the auxiliary drive 2 acted upon, primarily by introducing a torque about the axis of the closer shaft 1w , The driving arm 3m is the same as in the embodiment of 1 as a one-armed lever with driver 3mm educated. However, the Mitnehmerarm at its extended free end a control pin 3aa whose function will be described in more detail below.

The determination of the angular position of the clutch lever 20ke in his from the driving arm 3m disengaged position, ie when the clutch lever 20ke in the door opening angle range greater from about 15 ° of that on the Mitnehmerarm 3m arranged driver 3mm is disengaged takes place in the embodiment in 4 by a locking arm 20aa , Reference is made to the following 4.1 . 4.1a and 4.2 . 4.2a and 4.3 . 4.3a , The locking arm 20aa is on the guide housing 20kh pivotally mounted and is in the disengaged position of the clutch lever 20ke in its locked position (see 4.5 as well as the 4.1 . 4.1a and 4.2 . 4.2a ). In the locking position is the locking lever 20aa in alignment with the longitudinal extent of the guide housing 20kh and the guide slot 20khs , The locking arm 20aa is in this position with its free end in engagement with the free end of the piston rod 20gks that is, with the arranged at the free end of the piston rod guide pin, in the guide slot 20khs in the case 20kh is guided. In this locking position of the Arretierarms 20aa is the Arretierarm 20aa also aligned with the movement and power transmission direction of the piston rod 20gks , So that in this position a dead center position is obtained, in which the piston rod 2gks over the locking arm 20aa the clutch lever 20ke holds in its disengaged angular position in abutment and thus a dead center position is realized. The locking arm 20aa forms in its locking position a manipulation protection device. He prevents the clutch lever 20ke is pivoted in its disengaged position, ie in the open position of the door by hand from its locked angular position.

The dead center position is automatically canceled when the door reaches the specified door opening angle in the closing direction when closing, in the case shown this is a door opening angle of approx. 15 ° (see 4.5 and 4.6 ). In this door opening angle comes the locking arm 20aa in abutment with the control pin 3aa , at the free end of the driver arm 3m is arranged. But there are also modified versions possible, in which the control pin 3aa on the sliding arm 1ka of the main drive 1 is stored. The locking arm 20aa will on further closing by the control pin 3aa taken along, ie in the illustration in 4 turned counterclockwise. The locking position of the Arretierarms 20aa is thus repealed, ie the free end of Arretierarms 20aa comes out of engagement of the guide pin on free end of the piston rod 20gks , At the free end of the Arretierarms 20aa a locking recess is formed in the in the locking position at the free end of the piston rod 20gks arranged guide pin engages. The piston rod 20gks becomes during the locking arm 20aa pressed out of engagement is first retracted a piece. Once the engagement of the Arretierarms 20aa but is canceled, there is an extension of the piston rod 2gks under the effect of the gas spring 2GD , In this extension of the piston rod is the connecting link 20vl emotional. The at the end of the connecting link 20vl arranged guide pin runs in the guide slot 20khs , The connecting link leads with his on the clutch lever 20ke hinged end pivotal movement from the guide housing 20kh out and thereby pivots the clutch lever 20ke in this door opening area due to the geometric arrangement in engagement with the driver 3mm arrives. The clutch lever 20ke is the same as in the embodiment of 1 designed as a coupling claw with Fangausnehmung. The pivoting movement of the clutch lever 20ke driven by the gas spring 2GD acts on the driver 3mm such that the further closing operation in the sense of a closing delay and simultaneous closing of the door under the action of the gas spring 2GD as an auxiliary drive. 4.3 shows the closed position of the door. The locking lever 20aa is swung out, ie not in the locked position. The locking lever 20aa is under the action of the driver arm 3m arranged tax pencil 3aa held in this swung position.

During the opening process, a reverse action of the gas spring takes place as an auxiliary drive in comparison to the closing process. The gas spring 2GD will when opening, as long as the clutch lever 20ke with the driver 3mm engaged, loaded. It is done by an opening loss. The locking arm 20aa is by a return spring in its aligned alignment with the guide housing 20kh reset while the door is opened. The clutch lever 20ke is under the action of the driver arm 3m arranged driver 3mm during the opening process, as long as he is with the driver 3mm is coupled, swung back. The connecting link 20vl is doing while retracting the piston rod 2gks back into the guide housing 20kh into it swung. As soon as the predetermined door opening angle is reached, when the door is opened further, the clutch lever is disengaged 20ke from the driver 3mm , The locking arm 20aa passes under the action of its return spring with its free end in abutment on a guide housing 20kh trained stop 20kha and finally in abutment with the guide pin at the free end of the piston rod 20gks , so that the dead center is set again (see 4.1 . 4.1a and 4.2 . 4.2a ).

There are also compared to the embodiments of the figures, in which the driver rotatably connected to the output shaft 1w is connected and a torque about the axis of the output shaft 1w through the auxiliary drive 2 introduced, modified versions possible. The modifications may be designed, for example, to the effect that the drive unit 2GD of the auxiliary drive 2 not on the slide rail 1ks of the main drive 1 but on the drive unit 1g of the main drive 1 is stored, preferably in, on or on a housing of the drive unit 1g , In this modified embodiment, the auxiliary drive 2 same as in the embodiments of the figures via a clutch lever 20ke on the driving arm 3m act. It can do this on the driver arm 3m same as in the embodiment of 1 a cooperating with the coupling device driver 3mm be arranged, which cooperates with the coupling device. The drive mechanism of the auxiliary drive 2 with the gas spring 2GD and the piston rod 2gks may act on the coupling device, preferably on a comparably mounted coupling element in the same manner as in the embodiments of the figures and be constructed in principle in the same way as provided there. The coupling element can be designed in the same way as a pivotally mounted clutch lever, preferably as a clutch claw with a pivot bearing, in the modified embodiment preferably on the drive unit 1g , in particular on a housing of the drive unit 1g supported.

Furthermore, modifications of the embodiments shown in the figures are possible in which the catching recess, which is formed in the embodiments shown in the figures in the coupling element, in the modified embodiments, based on the embodiments of 1 and 4 based, the catching recess on the driver, in particular in the Mitnehmerarm 3m is trained. The respective associated coupling element has in these modifications to a driver which cooperates with the catching recesses in a corresponding manner as in the embodiments of the figures.
