Description

There are for example 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 pivoting door leaves. The drive unit is mounted on the sash or frame side, depending on the local conditions and application. The power transmission device is supported on the opposite side, ie on the frame side or on the sash side. In this known manual door drive, the drive unit comprises 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 to which the power transmission device is connected is also mounted. In practice, this can be designed as a scissor linkage device or slide arm slide rail device.

An electromechanical door drive, which is formed in a comparable manner 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, the output shaft of which is connected to the power transmission device, which can be designed as a scissor linkage device or slide arm slide rail device in the same way as with the above-mentioned manual door closer. The electromechanical drive is mounted in a comparable way on a door with a 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 move into the locked position in the lock while overcoming the lock latch. In the case of the known manual door closers with hydraulic damping, a so-called hydraulic end stop is generally provided for this purpose, which consists in the hydraulic damping having a bypass in the final phase during the closing process. In practice, this often causes the door to slam with a loud bang when the door slams shut. If the latching action is set weaker, the spring force of the closing spring may not be sufficient to close the door at the end of the closing process, i.e. it can happen that the door does not come into the closed position, the lock latch is not overridden and the door leaf just leans against the frame before reaching the closed position.

In the known electromotive door drives, the motorized opening and / or closing process can be controlled via an electrical control device. However, in order for the drive to function reliably and safely, constant maintenance and control settings are required. A failure of electrical components usually leads to a complete standstill of the drive, so that the maintenance and inspection measures mentioned are permanently required. Furthermore, the electric drive basically requires a power connection. In practice, manual door drives are therefore often preferred.

There are also known door pullers and door dampers that are used on doors in buildings and can only be coupled to the door during the closing and opening process in the vicinity of the closed end position and thus only act on the door in this part of the closing and opening process. These drive devices also have a drive unit to be mounted on the frame side or on the sash side with a power transmission device, but which have a linkage that can be automatically engaged and disengaged. In the EP 2 468 998 A1 such a drive is described with a linkage that can be automatically engaged and disengaged. Similar to a manual hydraulic door closer, the drive unit has a spring accumulator with hydraulic damping device which interacts with a slide arm on the output side which automatically engages and disengages in a slide rail during the closing and opening process.

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

The invention is based on the object of designing a composite drive system comprising a main drive and an auxiliary drive in such a way that the drive has a compact structure and provides advantages in terms of opening and / or closing movement when operating on the door.

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

It is a door drive for a door of a building with a door leaf pivotably mounted in a fixed door frame around a vertical door axis, preferably in door hinges.

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

The main drive is to act on the door leaf to execute a closing movement and / or opening movement and / or Closing damping and / or opening damping, preferably designed as a manual closing spring drive or as an electromotive door drive.

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

The auxiliary drive is designed to act on the door leaf to carry out a 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, reverse assembly is also possible, i.e. 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 main claim 1 that the output of the drive unit of the main drive is designed as an output shaft and that a driver is axially connected to the output shaft in a rotationally fixed manner on the output shaft, the driver as a component formed separately from the slide arm of the main drive is trained. The driver can preferably be designed as a driver lever or as a driver disk or as a driver axle piece. Here, the driver lever can be designed as a one-armed lever or as a multi-armed lever. The drive plate can preferably be an eccentrically mounted round or non-round plate or e.g. can also be designed as a cam disk. The driver axle piece can be designed as an axle piece in the configuration of an axle extension piece. What is essential for the different designs is the non-rotatable mounting of the driver on the output shaft with the bearing in the axial area of the output shaft and the design of the driver as a separate component from the slide arm of the main drive. The driver is preferably connected directly to the output shaft. Due to the above-described arrangement and mounting of the driver on the output shaft, the driver rotates with the output shaft.

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

This means that the auxiliary drive acts on the output shaft of the main drive in the phase of the opening or closing movement, in addition to the action already taking place on the output shaft by the drive unit of the main drive. As a result of the additional loading of the output shaft by the auxiliary drive, the main drive is thus supported by the auxiliary drive in order to obtain the desired door movement in the described phases of the closing process and / or opening process.

This additional loading of the output shaft of the main drive takes place in the solution according to main claim 1 by the auxiliary drive in such a way that the output shaft receives an additional application of torque about the axis of the output shaft. An additional torque is thus introduced into the output shaft of the main drive by the auxiliary drive, so that the closing process or opening process is supported by transmitting the rotary movement from the output shaft to the slide arm. Additionally or alternatively, the auxiliary drive can act on the output shaft in the form of a transverse force application with a force direction transverse to the axis of the output shaft. As a result of this application of force, an application of force is applied to the output shaft which has a direction of force which is directed directly into the direction of movement of the door leaf when opening or closing. This results from the geometric relationships of the main drive, which is designed as a sliding arm drive. The output shaft, to which the slide arm linkage consisting of slide arm and slide rail is connected, is in slide arm drives of this structure, namely in the mounted position on the door, in each case parallel to the axis of rotation of the door, so that the transverse force acting on the output shaft on the door leaf with a direction of force the opening or closing movement of the door acts. This means that in the case of transverse force acting on the output shaft by the auxiliary drive, the support of the main drive is supported by additionally pulling the door closed during the closing process and additionally pressing the door open during the opening process.

Now to the solution according to the invention according to main claim 2: It is essential in the drive according to 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 is supported to transmit transverse forces with the direction of force transverse to the axis of the output shaft and / or a driver is supported in a bearing that is stationary to the drive unit of the main drive to transmit forces with the direction of force transverse to the axis of the output shaft.

It is essential in this solution that the driver is always designed so that it transmits transverse forces at least to a certain extent. In designs in which the driver is supported on the output shaft, the design is such that it transfers transverse forces with the direction of force transverse to the axis of the output shaft to the output shaft or the bearing of the output shaft in the drive unit. In designs in which the driver is preferably offset and preferably supported at a distance from the output shaft in a bearing that is stationary to the drive unit of the main drive, the configuration is such that the driver is designed to transmit forces with a force direction transverse to the axis of the output shaft.

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

In the solution according to main claim 2, the output of the auxiliary drive in the coupled position acts on the driver in such a way that in the designs in which the driver is supported on the output shaft to transmit transverse forces, transverse force is applied to the output shaft with a force direction transverse to the axis of the output shaft is obtained and in the case of designs in which the driver is supported on the bearing that is stationary with the drive unit of the main drive, a force is applied to the relevant stationary bearing, also with a force direction the same as the transverse force application of the output shaft, namely with a force direction transverse to the axis the output shaft. This loading of the output shaft mounted in the drive unit of the main drive and / or the bearing that is stationary with the drive unit represents an application of force with a force direction directly in the direction of movement of the door leaf when opening or closing. This results from the geometrical relationships of the main drive, which is designed as a sliding arm drive. The output shaft mounted in the drive unit of the main drive, to which the sliding arm linkage is connected, exists in the state mounted on the door, namely parallel to the axis of rotation of the door, so that the relevant application of force to the output shaft or the stationary bearing acts on the door leaf in the direction of the Opening movement or the closing movement.

In preferred embodiments it can be provided that the driver has an axis of rotation that is axially aligned with the axis of the output shaft of the main drive,
wherein the driver is designed to be rotatable relative to the output shaft about its axis of rotation, or wherein the driver is designed to be non-rotatable with the output shaft.

The one 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. around a vertical axis of rotation in door hinges B. pivotable in a fixed door frame R. is stored.

The door drive 10 consists 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, namely as a sliding arm door closer. It comprises a door closer unit with a door closer housing 1g that is on the door leaf F. is mounted. In the door closer housing 1g is a door closer mechanism with a closer 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 is formed by a door closer shaft rotatably mounted in the door closer housing 1w . As in 1 .2 can be seen on the door closer shaft 1w a force-transmitting linkage connected as a slide arm 1ka and slide rail 1ks is trained. As in 1 .3 can be seen, the slide arm 1ka with a slide 1kag arranged at its free end is in the slide rail 1ks guided. The slide rail 1ks is on the stationary door frame R. assembled. The slide arm 1ka with the slide rail 1ks forms the power transmission device of the main drive 1 .

As best in the 1 .1a, 1.1 b and 1.1 c can be seen, is the auxiliary drive 2 including its coupling device 20k on 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 driver arm 3m together, the non-rotating on the door closer shaft 1w is stored. The driver arm 3m is like the sliding arm 1ka with the door closer shaft 1w non-rotatably connected. The driver arm 3m is designed as a separate component, ie the driver arm 3m and the sliding arm 1ka are two separately designed components. The driver arm 3m is in the illustrated embodiment, as can be seen from the figures, designed as a one-armed lever. At one end it is non-rotatable on the door closer shaft 1w connected. The driver arm carries at its free end 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 drives is described in more detail below.

How 1 .1a shows all frame-side components of the main drive 1 and the auxiliary drive 2 including the coupling device 20k covered by a common cover panel. In the 1 .1b and 1.1c this cover is removed. In 1 .1c, the housing 2gg is also removed. The case 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, which in the illustrated embodiment as a gas pressure spring 2gd is formed with a piston rod 2gks. 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 driver arm 3m the door closer shaft 1w is the said coupling device 20k switched. It couples the drive unit during the closing process and during the opening process 2g of the auxiliary drive 2 from the driver arm 3m automatically off and on when the door reaches a predetermined opening angle, so that the auxiliary drive is engaged during the closing process and the opening process in a door angle range between the closed position and a predetermined opening angle, namely in the illustrated embodiment between the closed position and 10 ° door opening angle. As long as the auxiliary drive 2 is engaged, it supports the main drive 1 by having the closer shaft 1w applied with an additional torque. In the specific case shown, the auxiliary drive is 2 designed as a closer drive. The drive unit 2g includes a gas pressure spring as an energy store, which is charged during the opening process and discharged during the closing process. In addition to the energy store, a damping device is included with which the opening and closing speed can be influenced, preferably variably adjustable. The energy store 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 on the closer shaft in the coupled position 1w during the closing process - by discharging the gas pressure spring - with an additional closing force and closing delay. During the opening process - by charging the gas pressure spring - the loading is reversed, ie in terms of opening resistance and opening damping. In the disengaged position, the energy store is locked, ie it is neither charged nor discharged, it remains in the charged state.

As best in the 1 .3.1 to 1.3.5, the 1 .4.1 to 1.4.5, the 1 .5.1 to 1.5.5, the 1 .6.1 to 1.6.5 and the 1 .7.1 to 1.7.5 can be seen, includes the coupling device 20k a coupling body driven by the piston rod 20kk with a link slot and a clutch lever 20ke that in one in the case 2gg fixed pivot bearing is pivotably mounted and a link pin 20kks has, which is in the link slot of the coupling body 20kk is led. The coupling body 20kk is motion-proof with the output end of the piston rod 2gks connected and is in the housing 2gg slot-guided. In the specific case, there is a guide slot in the housing for this 2gg , in which one in the coupling body 20kk fixed pin is guided.

In addition is in the housing 2gg another guide rail device 20kf arranged on which the coupling body 20kk is longitudinally guided (see 1 .2). When moving the piston rod 2gks becomes the coupling body 20kk in the case 2gg Moved in this way guided. This is done over the link pin 20kks in the link slot of the coupling body 20kk guided clutch lever 20ke forcibly moved. The clutch lever 20ke is designed as a coupling claw and has a catch recess at its free end, with which it can be connected to the driver arm 3m arranged driver 3mm cooperates. The clutch lever 20ke is designed in the case shown as a coupling claw with a catch recess. The driver is in the coupled position 3mm in engagement in the catch recess of the clutch lever 20ke . The driver is in the disengaged position 3mm out of engagement. In the 1 .5 to 1.7 is shown how the clutch lever 20ke during the closing process near the closed position of the door with the driver 3mm comes into engagement. The clutch lever 20ke becomes by progressive movement of the coupling body 20kk driven by the piston rod on the output side 2gks , so swiveled with forced control. About the engagement of the clutch lever 20ke with the driver 3mm the auxiliary drive works 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 unit 1g generated torque and to that 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 process under the effect of the gas pressure spring discharging 2gd . In the engaged phase of the opening process, the gas pressure spring is activated 2gd charged.

There are compared to the embodiments in 1 Modified versions possible, where instead of the driver arm 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 disk. In the case shown, the driver cam disk is rotationally fixed to the output shaft in an eccentric position 1w coupled. The driver cam disk is out of round and has an outer edge 3mf which is connected to a corresponding coupling element, not shown, of a coupling device 20k cooperates. The coupling element, which is preferably designed as a coupling lever, preferably has a roller for this purpose, which in the coupled position on the outer edge 3mf the drive cam rolls off. The outer edge 3mf can be designed as a friction surface and / or as a sliding surface.

At opposite 2a In modified versions, the modification in preferred versions can be such that the outer edge of the driver clutch disc is used instead of the friction and sliding surface 3mf a correspondingly extending toothing, which in the coupled position with a counter-toothing, which is on a coupling element, not shown, of a coupling device 20k is formed, engages and meshes with this.

2 B shows a driver 3m , which is designed as a drive plate that has a catch recess 3mfa having. The drive plate is the same as the drive plate in 2a in an eccentric position non-rotatably with the output shaft 1w connected. The catch recess 3mfa acts in the coupled position with a coupling element, not shown, of a coupling device 20k together, which for this purpose preferably has a driver pin or a driver roller which, in the coupled position, engages with the catch recess 3mfa stands and rolls in this when the coupling element executes the appropriately controlled pivoting or rotary movement.

3a shows a driver designed as a driver axle piece 3m . The driver axle piece is designed in principle in the manner of an axle extension piece. In the case shown, the driver axle piece is rotationally fixed to the output shaft 1w coupled. The coupling takes place through complementary spur teeth on the output shaft 1w and driving axle piece 3m . The drive axle piece is axially on the output shaft via the spur teeth 1w arranged attached, ie the axis 3x of the driver axle piece is aligned with the axis of the output shaft 1w arranged. For interaction with a coupling element, not shown, of a coupling device 20k the driver axle piece has, at its upper free end, driver surfaces 3mff, which interact with complementary engagement surfaces of the coupling element, which is preferably pivotably or rotatably controlled. For this purpose, the coupling element can have engagement surfaces complementary to the driver surfaces 3mff, preferably formed in a catch recess of the coupling element in such a way that the surfaces assigned to one another are in positive engagement in the coupled position, e.g. in the form of wrench surfaces. With a correspondingly controlled rotary or swivel movement of the coupling element, the driver axle piece is acted upon by rotation about its axis 3x and thus the introduction of a torque into the output shaft 1w .

3b shows a driver also designed as a driver axle piece 3m . The driver axle piece is designed in the same way as the driver axle piece in FIG 3a , but instead of the driving surfaces 3mf is a rotatably mounted carrier roller 3mfr rotatably mounted on the free end of the driver axle piece. The axis of rotation of the role 3mfr aligns with the axis of the output shaft 1w . The corresponding coupling element of a coupling device 20k has a mating surface which, in the coupled position, engages the roller 3mfr stands under the introduction of transverse 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 driver axle piece in 3a is that in the embodiment in 3b the door closer shaft 1w by the auxiliary drive 2 is acted upon exclusively or at least primarily by transverse forces that act directly in the closing direction or opening direction of the door movement.

In the embodiment of 3a and also in the exemplary embodiments of the other figures, a transverse force can be applied to the output shaft 1w by the auxiliary drive 2 also take place to a greater or lesser extent. In these exemplary embodiments, it is primarily the application of drivers that are rotationally fixed to the output shaft 1w are connected, at least in preferred embodiments, however, an application of torque 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 driver designed as a driver axle piece 3m on the output shaft 1w of the drive unit 1g of the main drive 1 non-rotating and transferring transverse forces. The carrier roller 3mfr is rotatably mounted on the free end of the driver axle piece and for interaction with the coupling claw 20ke intended. The pivot bearing of the driver roller 3mfr is also transmitting transverse forces. If the door leaf from the in 3c open position shown a closing movement under the action of the drive unit 1g of the main drive 1 carries out, the coupling claw comes 20ke the clutch 20k with their catch recess in engagement with the driver roller 3mfr . The coupling claw 20ke is from the output of the auxiliary drive 2 driven and motion controlled. It is pivoted in a controlled manner during the further closing process, as in the previous embodiment of FIG 1 explained in more detail. It now takes place in the embodiment of 3c a loading of the driver roller 3mfr with transverse forces with the direction of force transverse to the axis of rotation of the driver roller 3mfr that are aligned with the axis of the output shaft 1w is trained. The connection of the carrier roller that transfers the transverse forces 3mfr with the output shaft 1w in their output shaft bearings in the drive unit, which also transmit transverse forces to a certain extent 1g this results in a corresponding loading of the entire drive unit 1g and thus the door leaf with a direction of force in the direction of the closing movement of the door leaf. Under the action of the auxiliary drive 2 the door leaf is pulled closed with a delayed closing action. This action of the auxiliary drive supports the action of the main drive, which is 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 loading by the auxiliary drive 2 takes place in the opposite direction during the opening process up to the specified angular position at which the coupling claw 20ke from the engagement of the driver roller 3mfr disengages.

The embodiment in the 4th .1 to 4.5 (hereinafter briefly 4th called) is a modification of the embodiment of 1 .1 to 1.7 (hereinafter briefly 1 called). The embodiment of 4th differs from the embodiment of FIG 1 , as follows. As far as the design of the components and their assignment is concerned, first of all focus on the 4th .4 and 4.5 referenced. In the embodiment in 4th is in contrast to the embodiments described above 1 the gas spring 2gd not pivotable on the slide rail 1ks of the main drive arranged, but in one on the slide rail 1ks arranged fixed bearing. Ie the gas pressure spring 2gd is fixed with its housing 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 direction of extent 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 piston rod extends and retracts 2gks the pivoting movement of the clutch lever 20ke controls. The connecting link 20vl is for this with its one end at the end of the piston rod 2gks and at its other end with the clutch lever 20ke each connected via a spherical bearing.

The clutch lever 20ke is in one with the slide rail 1ks fixed pivot bearing and is in the embodiment in 4th by the one from the piston rod 2gks controlled connecting link 20vl controlled. The leadership of the connecting link 20vl is designed in such a way that the swivel joint 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 led. In the illustrated embodiment in 4th is the guide slot 20khs linear in the direction of extension of the guide housing 20kh , ie also parallel to the direction of extent of the slide rail 1ks , educated.

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

Establishing the angular position of the clutch lever 20ke in his from the driver arm 3m disengaged position, ie when the clutch lever 20ke in the door opening angle range greater than approx. 15 ° from that on the driver arm 3m arranged driver 3mm is disengaged, takes place in the embodiment in 4th by a locking arm 20aa . Reference is made below to the 4th .1, 4.1a and 4.2, 4.2a and 4.3, 4.3a. The locking arm 20aa is on the guide housing 20kh pivoted and is in the disengaged position of the clutch lever 20ke in its locked position (see 4th .5 as well as the 4th .1, 4.1a and 4.2, 4.2a) . The locking lever is in the locked position 20aa aligned 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 , ie with the guide pin arranged at the free end of the piston rod, which is in the guide slot 20khs in the housing 20kh is led. In this locking position of the locking arm 20aa is the locking arm 20aa also aligned with the direction of movement and force transmission of the piston rod 20gks , so that in this position a dead center position is obtained in which the piston rod 2gks via the locking arm 20aa the clutch lever 20ke holds in its disengaged angular position in the stop and thus a dead center position is realized. The locking arm 20aa forms a tamper protection device in its locked position. It prevents the clutch lever 20ke in its disengaged position, ie in the open position of the door, is pivoted 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 4th .5 and 4.6). The locking arm comes in this door opening angle 20aa in the stop position with the control pin 3aa , the one at the free end of the driver arm 3m is arranged. However, modified versions are also possible in which the control pin 3aa on the sliding arm 1ka of the main drive 1 is stored. The locking arm 20aa is activated by the control pin when closing further 3aa taken along, ie in the representation in 4th rotated counterclockwise. The locked position of the locking arm 20aa is thus canceled, ie the free end of the locking arm 20aa comes out of engagement of the guide pin at the free end of the piston rod 20gks . At the free end of the locking arm 20aa a locking recess is formed into which in the locking position of the at the free end of the piston rod 20gks arranged guide pin engages. The piston rod 20gks becomes the locking arm 20aa pressed out of engagement is first retracted a little. As soon as the locking arm engages 20aa is canceled, however, the piston rod extends 2gks under the action of the gas pressure spring 2gd . When the piston rod is extended, the connecting link becomes 20vl emotional. The one 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 a pivoting movement from the guide housing 20kh out and swings the clutch lever 20ke , which in this door opening area due to the geometric arrangement in engagement with the driver 3mm got. The clutch lever 20ke is the same as in the embodiment of 1 designed as a coupling claw with a catch recess. The pivoting movement of the clutch lever 20ke driven by the gas pressure spring 2gd acts on the driver 3mm in such a way that the further closing process in the sense of a closing delay and simultaneous closing of the door under the action of the gas pressure spring 2gd takes place as an auxiliary drive. 4th .3 shows the closed position of the door. The locking lever 20aa is swiveled out, ie not in the locked position. The locking lever 20aa is under the action of on the driver arm 3m arranged control pin 3aa held in this pivoted position.

During the opening process, the gas pressure spring acts as an auxiliary drive, which is the opposite of the closing process. The gas spring 2gd is during the opening process as long as the clutch lever 20ke with the driver 3mm is engaged, charged. This results in an opening attenuation. The locking arm 20aa is brought into alignment with the guide housing by a return spring 20kh reset while the door is being opened. The clutch lever 20ke is acting on the driver arm 3m arranged driver 3mm during the opening process as long as it is with the driver 3mm is coupled, pivoted back. The connecting link 20vl is thereby retracting the piston rod 2gks back into the guide housing 20kh swiveled in. As soon as the predetermined door opening angle is reached, the coupling lever is disengaged when the door is opened further 20ke from the driver 3mm . The locking arm 20aa comes under the action of its return spring with its free end in the stop position on one of the guide housing 20kh trained stop 20kha and finally in the stop position with the guide pin at the free end of the piston rod 20gks so that the dead center position is set again (see 4th .1, 4.1a and 4.2, 4.2a).

There are also compared to the exemplary embodiments of the figures in which the driver is rotationally fixed to the output shaft 1w is connected and a torque about the axis of the output shaft 1w by the auxiliary drive 2 is introduced, modified versions are possible. The modifications can, for example, be designed 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 the same as in the embodiments of the figures via a clutch lever 20ke on the driver arm 3m act. It can do this on the driver arm 3m same as in the embodiment of 1 a driver cooperating with the coupling device 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 can act on the coupling device, preferably on a comparably mounted coupling element, in the same way as in the exemplary embodiments of the figures and, in principle, be constructed in the same way as provided there. The coupling element can be designed in the same way as a pivotably mounted coupling lever, preferably as a coupling 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 catch recess, which is formed in the coupling element in the embodiments shown in the figures, in the modified versions based on the versions of 1 and 4th based, the catch recess on the driver, in particular in the driver arm 3m is trained. In these modifications, the respectively assigned coupling element has a driver which interacts with the catch recesses in a manner corresponding to that in the exemplary embodiments in the figures.
