EP3247854B1 - Door comprising a door drive with main- and auxiliary drive and additional function components - Google Patents

Description

There are for example from the DE 3 742 213 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 called Be designed scissors linkage device or sliding arm slide 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 end 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, it can happen that the spring force of the closing spring is not 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 The door leaves only ajar on 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. 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 during the Closing and opening process, as described, automatically disengages and engages in a pivot bearing.

In practice, when door drives are used in certain buildings, the door drive must have additional functions, such as an electrical locking device for locking the door in the open position of the door leaf or a smoke detector function for controlling such an electrical locking device for the door, or that it can be equipped with corresponding functions . When used on double-leaf doors, a closing sequence control of the door leaf, i.e. the active leaf and the passive leaf of the double-leaf door, is often required as an additional function. Door drives are known, preferably with slide arm linkage, i.e. in particular slide arm door closers with closer springs and hydraulic damping, in which such additional functions are integrated into the slide rail by additional functional components. These components are usually arranged in the end section of the respective slide rail remote from the strip and interact with the slide of the force-transmitting slide arm of the door drive that is guided in the slide rail.

The DE 10 2011 087 695 A1 discloses an example of a door with a main drive and an auxiliary drive.

The exemplary embodiment shown in the figures is a door drive device which, in the specific case, is designed as a manual door closer device, that is to say with a closing spring accumulator 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 puller 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 drive device is designated in the figures with the reference number 10 and is shown in FIG Figure 1 mounted on a door 3. The door 3 is how Fig. 1 shows to a pivoting door which comprises a door leaf 3f which is pivotably mounted about a vertical door axis 3a via door hinges 3b in a stationary door frame 3r. In the case shown, the door leaf 3f is designed as a pivoting stop wing. In the case shown, the door drive device is designed as a device that is mounted on the door. It should be expressly pointed out, however, that the door drive device 10 of this construction can also be designed as a door drive device to be installed concealed inside 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 embodied 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. The door closer housing 1g is mounted on the door leaf 3f in the illustrated case. The closer mechanism is accommodated in the door closer housing 1g. It is not shown in 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 set 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 supported 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 connected to the drive unit 1g, ie the end facing the door closer shaft 1w, in a rotationally fixed manner. 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 over a slide 1kag engaging in the guide track of the rail. The slide rail 1ks is mounted horizontally on the upper horizontal spar of the stationary door frame 3r fixed to the door frame. The slide arm door closer 1 is in the illustrated case, as already mentioned, designed as an overlying slide arm door closer, ie the door closer housing 1g and the slide rail 1ks are each mounted on top. In the case shown, the door closer housing 1g is in the upper area of the door leaf resting on the door leaf 3f and the slide 1ks resting on the upper horizontal spar of the door frame 1r.

The auxiliary drive

The auxiliary drive 2 is designed as a door puller with damping in the case shown. It is a drive unit that is designed separately from the slide arm door closer 1 forming the main drive 1. As a drive unit 2g, it comprises a damped closing unit, which is mounted lying on the door leaf 3f, relative to the main drive 1 remote from the door axis, i.e. further away from the door axis than the door closer housing 1g of the main drive 1, at a distance next to the door closer housing 1g in the upper Mounted in the area of the door leaf. The closing unit 2g forms, as mentioned, 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 cooperates with a closing spring device 2gf. Let it be on the Figures 2.3 and 2.4 and on the Figures 3.3 and 3.4 referenced. The illustrated piston-cylinder unit 2gkz can be designed as a hydraulic damping device. Instead of the illustrated piston-cylinder unit 2gkz with closing spring 2gf, a gas pressure spring can also be provided. In the case shown, the cylinder 2gz of the piston-cylinder unit is pivotably mounted 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.

The power transmission device 2k of the auxiliary drive 2 is designed in the illustrated case as a slide rail linkage, which is composed of an angle arm 2ka as a slide arm and a slide rail 2ks as a rod bearing. The angle arm 2ka is designed as a slide arm that can be engaged / disengaged with respect to the slide 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 installation position, i.e. aligned parallel to the pivot axis of the pivot bearing 2gs, via which the drive unit 2g of the auxiliary drive 2 is mounted on the door leaf. The angle lever 2ka is designed as a right angle in the case shown. The connecting joint 2gg to the output end of the piston rod 2gks engages the outer vertex corner of the angle lever 2ka. The angle lever 2ka has a shorter leg and a longer leg. 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 mounted in the same way as the pivot bearing 2gs of the cylinder 2gz so that it is fixed to the wing. Both bearings 2kas and 2gs are mounted in a storage frame in a rigid mutual assignment. The pivot bearing 2kas forms an output bearing that is stationary with the drive unit. The connection of the angle arm 2ka in the area of its corner apex 2kae at the output end of the piston rod 2gks with the formation of 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 of the angle lever 2ka is designed as a slider 2kag and can be automatically engaged and disengaged from the slide rail 2ks of the door puller 2, which is mounted on the frame side. In the 2ks in the slide rail In the coupled position, the angle lever 2ka and the slide rail 2ks form a force-transmitting linkage as a special slide arm linkage with slide rail. The automatic coupling and uncoupling takes place when the door leaf reaches a predetermined door opening angle. This predetermined door opening angle is approximately 30 ° door opening angle in the illustrated embodiment. During the opening process and the 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 slide arm with its slider 2kag engaging in the slide 2ks.

As best seen in the Figures 2.3 and 2.4 as well as the Figures 3.3 and 3.4 recognizable, the pivotably mounted piston-cylinder unit 2gkz forms a toggle lever with its piston rod 2gks together with the likewise pivotably mounted angle lever 2ka in conjunction with the articulated connection in 2gg. The connecting joint 2gg forms the knee joint. Because of this knee joint configuration, the angle lever 2ka can assume two dead center positions. The one dead center position is the coupling / uncoupling position, which is in the Figures 3.3 and 3.4 is shown. In this position, the pivot points of the bearings 2gs, 2kas, 2gg lie in one 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 Fig. 1 assumes right end position in which the door is closed. This dead center position is in the Figures 2.3 and 2.4 shown. In this position, the pivot points of the bearings 2gs, 2gg, 2kag are in one line. The pivot point 2kag is formed by the slider of the sliding arm 2ka engaging in the slide rail 2ks in this position. In both dead center positions, the sliding arm 2ka is constantly locked in the associated angular position and thus the output of the connected drive unit 2g is also determined accordingly.

In the first dead center position, i.e. in the coupling / disengaging position of the sliding arm 2ka, the closing spring 2gf of the piston-cylinder unit 2gkz is more strongly tensioned than in the second dead center position, i.e. in the end position assigned to the closed position of the door. As a result of the first dead center position of the slide arm 2ka, the tension of the closer spring, i.e. the charge that the closer spring assumes in the engaged / disengaged position, is held in the disengaged position.

As soon as the slide arm 2ga is coupled into the slide rail 2ks, the first dead center position is automatically released during the closing process and the slide arm 2ka is driven in the closing direction by the action of the closing spring 2gf, relieving the bias of the closing spring 2gf. The sliding arm 2ga rotates in 3.2 clockwise and runs in the slide rail 2ks in Fig. 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 guided coupled in the slide rail 2ks.

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

For coupling and uncoupling the slider 2kag formed at the free end of the sliding arm 2ka, the sliding rail 2ks has an opening 2kö on the front. This opening opens out via an inlet slope into a slideway within the slide rail 2ks, in which the slider 2kag is guided in the opening direction after coupling during the closing movement and the return movement. This slide track in the horizontally mounted slide rail 2ks can be linear or non-linear, depending on the variant of the auxiliary drive 2. The coupling and uncoupling of the sliding arm 2ks takes place, as discussed, automatically during the opening and closing process.

The outer cover of the drive device components mounted on the sash side and the frame side:

A significant advantage in the illustrated embodiment results from the fact that, as shown in FIG Fig. 1 shown that all the components of the drive device mounted on the door leaf side, ie the door closer housing 1g and the drive unit 2g of the auxiliary drive 2, are covered by a common cover housing 3fh and all the components of the drive device mounted on the door frame side, ie the slide rail 1ks of the door closer and the slide rail 2ks of the door closer, are covered by a common cover 3rh. These cover housings 3fh, 3rh can each be designed as U-profiles. It is essentially advantageous that they are designed with a constant cross section over their longitudinal extent. They are preferably designed in such a way that they each extend over the entire width of the wing, have an identical longitudinal extension and can be mounted flush with one another at the ends. The cover housings 3fh, 3rh can each be formed in one piece, but it is also possible to form them from a plurality of partial sections over the longitudinal extent. The common cover 3rh and 3fh is formed continuously over the entire width of the door, which brings visual advantages.

The assembly of the sash-side and frame-side components on a common sash-side or frame-side mounting plate.

In the case shown, it is also advantageous to assemble the components to be mounted fixedly on the door leaf on a common mounting plate 3fm, which is preferably mounted in a standard hole pattern of the door leaf.

The same applies to the assembly of the components that are to be fixed to the door frame on a common mounting plate 3fm, which is mounted on the door frame side (see Fig. 1 ).

The mounting of the mounting plate 3fm to be mounted on the leaf side in a standard hole pattern of the door leaf means that the mounting plate 3fm is attached to the leaf via a mounting hole pattern that is formed in the section of the mounting plate close to the strip. This mounting hole pattern is in Fig. 1 in the left section of the mounting plate 3fm, in which the drive unit of the main drive 1, ie the door closer housing 1g of the sliding arm door closer is mounted. In the section of the mounting plate remote from the strip, in which the drive unit of the auxiliary drive 2, ie the drive unit 2g, is mounted, the mounting plate 3fm is not screwed to the wing, since no standard hole pattern is provided in this area of the wing.

In the case of the version to be mounted concealed inside the door, the components can be mounted separately inside in corresponding separate or continuous recesses in the sash and in the frame. However, assembly designs are also possible in which the sash-side components are mounted on a common mounting plate and the frame-side components are mounted on the inside on a common mounting plate. In this case, the components mounted on the common mounting plate form a preassembled structural unit that can be mounted sunk into a corresponding receiving recess in the sash.

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 in Figure 1 In the illustrated 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 slide arm 1ka rotates with the rotationally fixedly connected door closer shaft 1w about the axis of rotation of the door closer shaft 1w Figure 1 counterclockwise. The slide arm 1ka is guided with its free end designed as a slide in the slide rail 1ks in such a way that the free end of the slide arm 1ka in the illustration in FIG Fig. 1 runs to the left.

During this opening movement, the toggle-like slide arm 2ka of the auxiliary drive 2 also rotates in a corresponding manner in that the free end of the slide arm 2ka runs with its free end in the slide rail 2ks to the left in the illustration in the figures. The toggle-like sliding arm linkage, which is composed 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, which is fixed to the wing. In the illustrated embodiment, however, it is essential that this toggle-like linkage, ie the free end of the angled slide arm 2ka, automatically disengages from the slide rail 2ks as soon as the door opening angle predetermined for this is reached from the closed position. In the illustrated embodiment, this takes place at a door opening angle of approximately 30 °. In this angular position the toggle-like linkage 2k reaches its first dead center position. When uncoupling from the slide rail 2ks, the angle arm 2ka remains in the angular position of this dead center position. The angle arm is in this position is quasi locked against further rotation and in this angular position moves out of the front opening 2kö of the slide rail 2ks when the door is opened further. In the dead center position, the angle arm 2ka remains virtually 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 brought from the open position back into the closed position, the closing movement takes place with the angle arm 2ka disengaged up to the predetermined engagement angle position. The angle arm 2ka is therefore unchanged in the dead center position Figures 3.1 and 3.4 that 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 angle arm 2ka fixed in this engagement / disengagement angle position comes with its free end, ie the slider 2kag, to be coupled again into the slide rail 2ks. The free end of the slide arm 2ka with the slider 2kag moves into the opening of the slide rail 2ks. When the door is closed further, the free end of the angle arm 2ka is coupled into the slide rail 2ks and runs in the illustration in Fig. 1 guided in the slide track of slide rail 2ks to the right through slide rail 2ks. The toggle lever configuration has automatically released the engagement / disengagement latching position under the action of the slide rail guide. As soon as this dead center position is released, the closer spring, which has been kept tensioned until then, now acts as a rotary drive of the angle lever in the closing direction while discharging. In other words, the closing process is then supported by the auxiliary drive 2. The toggle lever finally reaches its in the closed position of the door Fig. 1 second dead center position shown. 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 opened again by manually pulling the door leaf open is pivoted. During this opening movement, the dead center position is automatically canceled by the pivoting of the angle arm 2ka and the closer spring is recharged.

This in Fig. 4 The second embodiment shown differs from that in FIGS Figures 1 to 3 illustrated embodiment only in that in the embodiment in Fig. 4 In addition, an electrically switchable tumbler 4 is mounted on the door. The electrically switchable tumbler 4 consists of a tumbler component 4r mounted on the frame side and a tumbler component 4f mounted on the sash side. The tumbler component 4r mounted on the frame side is an electrically switchable locking component, in the specific case an electric door opener. The electric door opener is mounted in the section furthest from the belt in the common rail housing, in that the slide rail 1ks of the main drive is formed in a section near the belt and the slide rail 2ks of the auxiliary drive is formed adjacent to it on the side of the slide rail 1ks facing away from the belts . The electric door opener that forms the tumbler component 4r mounted on the frame side is conventionally constructed with a movably mounted door opener latch that interacts with an electrically switchable locking device, preferably with an electromagnet. The door opener latch and the electrically switchable locking device with an activated gear form the electric door opener, which in the illustrated embodiment forms the tumbler component 4r mounted on the frame.

The tumbler component 4f mounted on the sash side is designed as a counter-element that connects to the tumbler component on the frame side cooperates. The counter-element is preferably designed in the manner of a resilient lock latch, which has a latch body with an inlet bevel, which is acted upon by a spring in the extension direction.

A significant advantage results from the specific embodiment in FIG Fig. 4 in that the sash-side tumbler component 4f is mounted on the common sash-fixed mounting plate 3fm. The door closer housing 1g of the main drive 1 is mounted on this mounting plate in the section near the belt and the drive unit 2g of the auxiliary drive 2 is mounted next to it. The mounting plate 3fm only has a screw fastening in the standardization hole pattern of the door leaf 3f in the section near the hinge. It is the section of the mounting plate 1fm close to the belt, in which the door closer housing 1g is attached to the mounting plate. In the sections of the mounting plate 3fm further away from the tape, in which the housing 2g of the auxiliary drive 2 and the leaf-side tumbler component 4f are mounted on the mounting plate, the mounting plate 3fm has no screw connection with the door leaf 3f. This results in advantages in connection with the assembly on standard doors that only have a standard hole pattern in the door leaf in the upper section of the door leaf in the area near the hinge.

Same as the one in the Figs. 1 to 3 illustrated embodiment is also in the embodiment in Fig. 4 a door-leaf-side cover housing 3fh which is continuous over the entire leaf width and is designed as a common cover housing under which all the components mounted on the leaf-side, namely the leaf-side component of the main drive 1, adjacent to it the leaf-side component of the auxiliary drive 2 and adjacent to it in the section furthest from the hinge wing-side component of the electrical tumbler 4 is arranged. Correspondingly, a common cover housing 3rh on the door frame side is also provided, which has the same length as the cover housing 3fh on the door leaf side and is mounted on the upper frame spar with ends aligned with it. All of the components mounted on the frame side are arranged under this frame-side cover housing 3rh, namely the slide rail 1ks of the main drive 1 in the area close to the belt, the slide rail 2ks of the auxiliary drive 2 adjacent to it and the frame-side component of the electrically switchable tumbler 4, which in the specific case is an electrical Door opener is designed.

Modified auxiliary drive

In the Figures 5.1 to 5.3 an auxiliary drive 2 is shown which, as 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 to the exemplary embodiments of the preceding figures is that the drive unit 2g is inserted under pressure, ie the piston rod 2gks is pushed into the housing, ie shortened, when the door is opened while charging the energy storage device. When the door is closed, the piston rod is pushed out, ie lengthened, while the energy store is discharged. For this purpose, the mounting of the drive unit 2g is designed to be modified accordingly compared to the exemplary embodiment of the preceding figures. In case of Figures 5.1 to 5.3 the piston rod 2gks acts on a link device mounted on the storage frame with a connecting link 2kav, which is connected with one end to the piston rod 2gks and with its other end The end engages the angle arm 2ka and is subjected to tension when the door is opened when the piston rod 2gks is extended.

As from the Figures 5.1 to 5.3 It can be seen that the drive unit 2g of the auxiliary drive 2 is mounted on a storage frame 2m, which, as in the previously described embodiment, is to be mounted fixed to the sash when the drive unit 2g is mounted on the sash. The drive unit 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 joint bearing 2gkg for the articulated support of the piston rod 2gks. The sliding arm 2ka is also designed as an angle arm in this exemplary embodiment, in the illustrated case also as a right angle with a first and a second leg. The first leg 2kaa is, as in Fig. 5.1 recognizable, offset in height with respect 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 stands vertically upwards 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 bearing frame 2m. The housing of the drive unit 2g is also mounted in the same pivot bearing 2kas. The connecting link 2kav connects the spherical bearing 2gkg, in which the output-side end of the piston rod 2gks is supported, with the arranged in the apex of the angle arm 2ka bearing 2kas, in which the connecting link 2kav is articulated with one end in the pivot bearing 2gkg and with its other end in the apex bearing 2kas.

The height offset of the angle arm 2ka, ie the height offset of the lever arms 2kaa and 2kab to one another, is in the case of the in Figure 6.1 and 6.2 illustrated embodiment adjustable. This embodiment corresponds in structure and function to the embodiment of FIG Figures 5.1 to 5.3 . The adjustability of the height offset takes place, as from the Figures 6.1 and 6.2 emerges via an elongated screw connection 2kj of the two arms 2kaa and 2kab. In the embodiment shown, two elongated holes are formed in the vertical offset piece 2kah of the first arm 2kaa, into which fastening screws engage, which are fixed in fastening holes of the second arm 2kab, for example by means of a screw connection with nuts. They form a height-adjustable clamping connection of the two arms 2kaa and 2kab in order to adjust the height offset to match the height position of the drive unit 2g with respect to the slide rail 2ks.

Modified drive with assembly space M

The embodiment of Figures 7.1 to 7.4 shows a modification of the embodiment of the drive of the preceding figures. The modification is also a composite drive consisting of 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, ie the slide the slider 2kag of the auxiliary drive 2 is in one plane, the front is in front of the slideway of the slider 1kag of the main drive 1. As in the Figures 7.1 to 7.3 As can be seen, the sliding path of the slider 2kag of the auxiliary drive 2 can more or less overlap the sliding path of the slider 1kag of the main drive 1. However, it is essential that the two slideways are offset parallel to one another towards the front and thus do not interfere with 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 in a conventional manner Mounting space can be arranged that lies in the slide 1ks or in an extension line of the slide of the slider 1kag of this slide, since the slide 2ks of the auxiliary drive 2 is arranged outside this assembly space, ie leaves this assembly space free.

The structure of the drive device of the Figures 7.1 to 7.3 is in the exploded view in Fig. 7.4 recognizable in detail.

Bottom left in Fig. 7.4 the drive device 10, which is composed of the main drive 1 and the auxiliary drive 2, is shown in the assembled state. The drive device 10 comprises components to be mounted on the frame side, which are covered with a uniform U-shaped cover 3rh, and components to be mounted on the wing side, which are covered with the uniform U-shaped cover 3fh.

In the Figures 8a-8c and 9 The illustrated exemplary embodiments are each a door drive which is composed of a main drive 1 and an auxiliary drive 2.

The main drive of the second embodiment:

The main drive 1 is in the illustrated case a sliding 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 rotationally fixed manner to an output shaft 1w mounted in a housing of the drive unit 1g and is guided on the slide rail 1ks which is mounted fixed to the frame. In the exemplary embodiment shown, the main drive should be designed as 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:

The auxiliary drive 2 is formed in the illustrated case from a drive unit 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 slide rail 1ks of 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 energy store 2f or the electric motor interacts with the slider 2kag guided in the slide rail 2ks. This is a slider at the free end of the sliding arm 2ka. The sliding arm 2ka is pivotably mounted with its bearing end in a pivot bearing 2kd mounted on the wing side and is guided with its free end over 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 so as to be linearly movable in the slide rail 2ss along the guide track of the rail. The 2kag glider is taken along. The slide rail 2ss forms an output bearing that is stationary with the drive unit 2g.

The output 2aa is guided in the guide track of the slide rail and is thus a linear output. In the illustrated embodiment, the guide track of the slide rail is linear and extends horizontally. It should be noted that the output 2aa is also understood as a linear output if, in a modified embodiment, the guide track of the slide rail is designed as a non-linear cam track. It should also be pointed out that other 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 guide track 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 one Threaded nut runs, which is linearly guided in the guideway and drives the slide arm 2ka, for example by taking along the slider 2kag.

As from the Figures 8b and 8c It can be seen that the slide arm 2ka of the auxiliary drive 2 can be engaged and disengaged from the drive unit 2g in the slide rail 2ks.

The coupling / uncoupling point is in the exemplary embodiment Figures 8b , 8c formed between the free end of the slide arm 2ka and the driven member 2aa of the drive unit 2g mounted in the slide rail 2ss, ie between the connection end of the slide arm 2ka and the output of the drive unit 2g.

The coupling and uncoupling takes place automatically during the opening and closing process at a certain door opening angle. The Figure 8b shows the door position in the door opening angle at which the coupling takes place during the closing process and disengaging during the opening process. If the door opening angle is smaller than this disengagement and engagement angle position, the sliding arm 2ka is engaged (see Figures 8b and 8a ). If the door opening angle is greater than the engagement / disengagement angle position, the slide arm is disengaged (see Figure 8c ).

In the disengaged position, the slide arm 2ka remains on the rod bearing in this exemplary embodiment, ie in the case shown in FIG Figure 8c on the wing-side pivot bearing 2d, projecting from the wing F in a locked angular position. The angular position can be locked by a latching device that 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 / uncoupling, ie the angular position in Figure 8b . While the sliding arm 2ka is disengaged, the spring energy store 2f of the drive unit 2g remains in the charged position in which the disengagement has taken place. It is the charged position that the spring accumulator 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 disengaged and switched off with the release of the spring accumulator when the sliding arm 2ka is engaged.

The coupling process between the free end of the slide arm 2ka and the slider 2kg guided in the slide rail 2ks takes place automatically when the door is closed at the predetermined door opening angle, which in Figure 8b is shown. The free end of the sliding arm 2ka protruding in this angular position moves with its slider 2kag into the slide rail 2ks in this door open position, namely via an inlet slope, not shown, through a front opening of the slide rail 2ks and couples with the slider that is in waiting position therein Output member 2aa. With the coupling, the spring energy store 2f arranged in the slide rail and charged during the previous opening process is forcibly released. As a result of the discharge of the spring accumulator 2f which takes place in this way, the slider 2aa together with the slider 2kag and slide arm 2ka coupled thereto is driven in the closing direction. The coupled sliders 2kag and 2aa are moved to the right in the illustration in the figures and the sliding 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, which is in Figure 8a is shown. In the closed position, the sliding arm again reaches a latching position in which it remains until the door is then opened again for passage. This is done manually by pivoting the door leaf F in the opening direction.

During the opening movement of the door leaf, the sliding arm 2ka is rotated in the illustration in the figures about the pivot bearing 1kd in the counterclockwise direction. The slider 2kag with the output slider 2aa is 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 opening and closing angle of the door, which is in Figure 8b is shown, reached, the disengagement of the sliding arm 2ka takes place automatically. The decoupled sliding arm 2ka then remains fixed in the predetermined angular position that it assumes when it is decoupled, protruding from the wing-side pivot bearing 1kd.

After the sliding arm 2ka has been disengaged, the output slider 2aa also remains in its position which it assumed when it was disengaged, fixed by the already mentioned locking device. Due to this automatically occurring detection, the storage spring 2f connected to the output slider 2aa also remains in the charged state as long as the slide arm 2ka is disengaged, which the storage spring 2f has reached through the preceding opening process with the slide arm 2ka engaged.

The auxiliary drive 2 is thus charged during the opening process as long as the sliding arm 2ka is coupled, ie 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, ie at the end of the closing process until the door has reached the closed position.

Fig. 9 shows a modified embodiment which differs from the embodiment of FIG Figures 8a-8b The difference is that the coupling / uncoupling 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, which is 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, as long as it is uncoupled, in the angular position which it assumed when it was uncoupled. Here, too, a locking device for the angular position of the disengaged sliding arm and a locking device for charging the storage spring 2f are 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 manner similar to the embodiment of FIG Figures 1 to 4 . This means that in this exemplary embodiment too, the accumulator spring 2f remains in the charged position that it had when the sliding arm 2ka was disengaged.

What is essential for the Figures 8 and 9 illustrated embodiments that the frame-side mounted components of the main drive 1 and the auxiliary drive 2, ie the slide 1ks of the main drive 1 and the slide 2ss with the storage spring 2f stored 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 bearings 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 sash-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 mounting plate 3 rm on the frame side can also be provided for the assembly of the frame-side components.

Even with these in the Fig. 8 and 9 In the illustrated embodiments, 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 rotary bearing 2kd, preferably on the common wing-side mounting plate on which the rotary bearing 2kd and the drive unit 1g of the main drive are also installed.

In a modification of the embodiment in Figure 9 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 rack arranged in the slide rail 2ks.

Versions of the drive device are also provided in which the main drive 1 is designed as a sliding arm drive, preferably a sliding door arm closer with a closer spring and hydraulic damping device, and a slide rail with an electrical locking device is used as the sliding arm 1ks in order to be able to keep the door leaf open via the electrically switchable locking device. The electrically switchable locking device can be designed as a unit which is mounted on the inside of the slide rail 1ks and which interacts with the slider of the slide arm 1ka. The electrical locking device can be designed as a retrofittable unit for use in the slide rail 1ks. But it can also be designed as a component of an electric locking rail. The electrical locking rail can be designed as a functional rail of a sliding arm door closer program and contain the electrical locking device.

Other functional rails of a sliding arm door closer program can also be used as slide rails 1ks, e.g. slide rails, preferably designed as electrical locking rails with smoke detectors.

The drive device can also be designed for double-leaf doors, for example for a door with active leaf and passive leaf. The drive device on the active wing side and the drive device on the passive wing side can be designed identically, that is, each with an identical main drive 1 and an identical auxiliary drive 2. In this case, the components to be mounted on the frame side and the components to be mounted on the wing side can each be mounted on a common mounting plate that extends over the entire width the double-leaf door is designed as a one-piece or multi-piece mounting plate. The frame-side components of the Both door leaves can also be covered by a common continuous cover.

The frame-side slide rail of the active wing drive device and the frame-side slide rail of the passive wing drive device can also be designed as a continuous unit, e.g. continuous slide rail.

In the case of versions for double-leaf doors, components of a closing sequence control, preferably mechanical closing sequence control, can also be used as frame-side components in the slide rail and are preferably installed in the frame-side slide rail of the active wing and in the frame-side slide rail of the passive wing, preferably in a continuous slide rail that is extends over the entire width of the double-leaf door. In the case of closing sequence control, it is provided that the passive leaf blocks the closing movement of the active leaf via its sliding arm or an element connected to the sliding arm. For this purpose, mechanical components, for example push rods or Bowden cables, are provided in the slide rail, which extend along the slide rail from the passive wing side to the active wing side. In particular, it is provided that these mechanical components are guided past the components of the auxiliary drive. The slide rail can preferably be constructed in two or more stages, with the components of the auxiliary drive or the sliding elements of the auxiliary drive being guided in the first compartment of the slide rail and the mechanical components such as push rods or Bowden cables being guided in the second compartment of the slide rail. The two compartments of the slide rail can be arranged vertically one above the other or horizontally next to one another.

The one in the Figures 10.1 to 10.7 The first embodiment shown is a door drive 10 mounted on a door. The door has a door leaf F which is mounted in door hinges B in a stationary door frame R such that it can pivot about a vertical axis of rotation.

The door drive 10 is composed of a main drive 1 and an auxiliary drive 2.

The main drive 1 is designed in this specific case as a door closer, specifically as a sliding arm door closer. 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 there is a door closer mechanism with a closer spring and a damping device, preferably 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 assembly is formed by a door closer shaft 1w rotatably mounted in the door closer housing. As in Fig. 10.2 can be seen, a force-transmitting linkage is connected to the door closer shaft 1w, which is designed as a slide arm 1ka and slide rail 1ks. As in Fig. 10.3 It can be seen that the slide arm 1ka is guided in the slide rail 1ks with a slide 1kag arranged at its free end. The slide rail 1ks is mounted on the stationary door frame R. The slide arm 1ka with the slide rail 1ks forms the power transmission device of the main drive 1.

As best in the Figures 10.1a , 10.1b and 10.1c As can be seen, the auxiliary drive 2 including its coupling device 20k is mounted on the front side of the slide 1ks of the main drive 1. In the exemplary embodiment shown, the auxiliary drive 2 interacts with the sliding arm 1ka of the main drive 1 via the coupling device 20k, as will be described in more detail below. How Fig. 10.1a shows, all frame-side components of the main drive 1 and the auxiliary drive 2 including the coupling device 20k are covered by a common cover panel. In the Figures 10.1b and 10.1c this cover is removed. In Fig. 10.1c the housing 2gg is also removed. The housing 2gg forms the bearing housing of the drive unit 2g of the auxiliary drive 2 and also the bearing and guide housing of the coupling device 20k.

The auxiliary drive 2 has a drive unit 2g, which in the illustrated embodiment is designed as a gas pressure spring 2gd with a piston rod 2gks. The piston rod 2gks forms the output of the drive unit 2g of the auxiliary drive 2. The aforementioned coupling device 20k is connected between this output of the auxiliary drive 2 and the sliding arm 1ka of the main drive. During the closing process and during the opening process, it automatically disengages and engages the drive unit 2g of the auxiliary drive 2 and the sliding arm 1ka of the main drive 1 when the door reaches a predetermined opening angle, so that during the closing process and the opening process in a door angle range between the closed position and a predetermined one Opening angle, namely in the illustrated embodiment between the closed position and 10 ° door opening angle, the auxiliary drive is coupled. As long as the auxiliary drive 2 is coupled, it supports the main drive 1. In the specifically illustrated case, the auxiliary drive 2 is designed as a closer drive. The Drive unit 2g comprises 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 storage device, a damping device is included with which the opening and closing speed can be adjusted. The energy store is charged during the opening process, in the phase of the opening movement in which the auxiliary drive 2 is engaged, and discharged during the closing process in the phase in which the auxiliary drive is engaged. 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 Figures 10.3.1 to 10.3.5 , the Figures 10.4.1 to 10.4.5 , the Figures 10.5.1 to 10.5.5 , the Figures 10.6.1 to 10.6.5 as well as the Figures 10.7.1 to 10.7.5 As can be seen, the coupling device 20k comprises a coupling body 20kk driven by the piston rod with a link slot and a coupling lever 20ke which is pivotably mounted in a pivot bearing fixed in the housing 2gg and has a link pin 20kks which is guided in the link slot of the coupling body 20kk. The coupling body 20kk is connected to the output end of the piston rod 2gks in a fixed manner and is guided in a slot in the housing 2gg. In the specific case, there is a guide slot in the housing 2gg, in which a pin fixed in the coupling body 20kk is guided.

In addition, a guide rail device 20kf is arranged in the housing 2gg, on which the coupling body 20kk is guided longitudinally (see Fig. Fig. 10.2 ). When the piston rod 2gks is moved, the coupling body 20kk is moved in the housing on 2gg, guided in this way. In this case, the via the link pin 20kks in the link slot of the coupling body 20kk guided clutch lever 20ke forcibly moved. The coupling lever 20ke has a catch recess at its free end, with which it interacts with a driver 1km arranged on the sliding arm 1ka. In the coupled position, the driver is 1km in engagement in the catch recess of the coupling lever 20ke. In the disengaged position, the driver is 1km out of engagement. In the Figures 10.5 to 10.7 shows how the coupling lever 20ke comes into engagement with the driver 1km during the closing process in the vicinity of the closed position of the door. The coupling lever 20ke is driven by the progressive movement of the coupling body 20kk by the piston rod 2gks on the output side, that is, it is pivoted in a positively controlled manner. Via the engagement of the clutch lever 20ke with the driver 1km, the auxiliary drive 2 acts on the sliding arm 1ka of the main drive 1 and thus supports the main drive 1 in the engaged phase of the closing process under the effect of the gas pressure spring 2gd which is discharged. In the engaged phase of the opening process, the gas pressure spring 2gd is charged.

In the second embodiment, shown in FIG Figures 11.1 to 11.3 , it is a modified version compared to the embodiment of Figures 10.1 to 10.7 . The only modification is that the coupling device 20k with the coupling lever 20ke interacts directly with the slider 1kag of the sliding arm 1ka of the main drive 1 and not directly with the sliding arm 1ka. Immediately, however, means in each case with the interposition of the driver 1 km fixed on the slider 1kag or on the sliding arm 1ka. The driver 1km is in the case of the exemplary embodiment Figures 11.1 to 11.3 arranged in or on the slider 1kag and the clutch lever 20ke interacts with this. In the coupled position, the driver is 1km in engagement with the catch recess of the clutch lever 20ke and in the disengaged position he is out of this engagement. The mode of operation is otherwise the same as in the embodiment of FIG Figures 10.1 to 10.7 .

For mounting opposite the hinge side, the exemplary embodiment in FIG Figures 10.1 to 10.7 however, advantages compared to the embodiment of FIG Figures 11.1 to 11.3 . The reason for this is as follows: As is known, when the hinge is mounted on the opposite side of the hinge, the glider 1kag runs in the glide rail 1ks with a small door opening angle with a direction reversal, while the direction of rotation of the sliding arm 1ka remains in the same direction over the entire closing process as well as over the entire opening process, ie there is no reversal of the direction of rotation of the sliding arm. The execution of the Figures 10.1 to 10.7 , in which the coupling device engages not on the slider 2kag but on the slide arm 2ka, can therefore be used in the same way as with the normal assembly on the hinge side, without any device modifications having to be made.

In the third embodiment, shown in FIG Figures 12.1 to 12.4 , it is a modified version of the Figures 11.1 to 11.2 . The modification is that the coupling device 20k is configured differently. In the embodiment of Figures 12.1 to 12.3 the coupling device 20k has a coupling lever 20ke which is articulated on the piston rod 20gks of the auxiliary drive 2. In addition, the clutch lever 20ke is the same in its central portion as in the embodiment of FIG Figures 11.1 to 11.3 in one with the housing 2gg of the drive unit 2g of the auxiliary drive 2 and with the slide rail 2ks of the Main drive 1 fixed pivot bearing 20kea pivotally mounted and cooperates with its free end with catch recess in principle in the same way with a driver 1km, which is arranged in the slider 1kag of the main drive 1, as in the embodiment of Figures 11.1 to 11.3 is explained. The housing 2gg accommodates the drive unit 2g of the auxiliary drive 2 including the piston rod 2gks and the coupling device 20k. In the embodiment of Figures 12.1 to 12.4 the driver 1km is designed as a driver pin 1km, which is arranged in the slider 1kag in the horizontal plane of movement of the slide arm 2ka but transversely to the direction of movement of the slider 1kag.

To control the clutch lever 2ke is instead of the clutch body 20kk in the execution of the Figures 12.1 to 12.4 a control lever 20ks is provided. In the case shown, the control lever 20ks is designed as a two-armed lever, the two lever arms of which form an apex angle of approximately 90 °. The control lever 20ks is rotatably mounted in its apex area in a pivot bearing fixed in the slide rail 1ks and / or in the housing 2gg. One lever arm interacts with its end with a control cam on the facing edge of the coupling lever 20ke. The other lever arm of the control lever 20ks interacts with its free end with a stop edge on the slider 1kag, in that the free end of this lever arm comes into contact with the stop edge formed on the slider 1kag at a predetermined small door opening angle during the closing process. At the same time, the coupling lever 20ke comes into engagement with its catch recess with the driver 1km. Due to the drive connection with the piston rod 2gks of the auxiliary drive 2, the control lever 20ks, which is in stop at the stop edge of the slider 1kag, is rotated counterclockwise in the illustration in the figures. The dem The lever arm associated with the clutch lever 20ke is at its free end with the cam of the clutch lever 20ke in stop and rotates the clutch lever 20ke in the counterclockwise direction forcibly with it. The slider 1kag of the sliding arm 1ka of the main drive 1, which is in engagement with the clutch lever 20ke via the driver 1km, is taken along in the closing direction.

Fig. 12.1 shows the situation during the closing process before the clutch is engaged, ie with a correspondingly large door opening angle.

The Fig. 12.2 shows the coupling as soon as the door leaf F reaches the predetermined small door opening angle.

The Fig. 12.3 shows the beginning of the rotary movement of the two levers, i.e. the rotary movement of the control lever 20ks through the stop position with the slider 1kag and the entrainment of the clutch lever 20ke through the actuation of the clutch lever 20ke by the control lever 20ks, by the lever arm of the control lever assigned to the control curve of the clutch lever 20ke 20ks acts on the control cam and rotates the clutch lever 20ke counterclockwise.

In Fig. 12.4 the closed position is shown. Both levers 20ks and 20ke are rotated counterclockwise in their end position. The control lever 20ks is still on the stop edge of the slider and the coupling lever 20ke is still in engagement with the driver 1km of the slider 1kag.

The one in the Figures 13.1 to 13.3 The illustrated embodiment, the door drive 10 is also composed of a main drive 1 and an auxiliary drive 2. The main drive 1 is designed as a sliding arm door closer, specifically designed the same as the main drive 1 of the Figures 10 to 12 . The auxiliary drive 2 is in the embodiment Figures 13.1 to 13.3 but different than in the Figures 10 to 12 designed. The auxiliary drive 2 in the Figures 13.1 to 13.3 namely has a drive unit 2g, which, however, is mounted on the door leaf. The output 2aa of the auxiliary drive 2 is coupled to a force-transmitting linkage which, in the case shown, is designed as a slide arm 2ka with slide rail 2ks. The linkage forms the power transmission device of the auxiliary drive 2. The slide rail 2ks is mounted on the door frame side. The free end of the slide arm 2ka can be engaged and disengaged with respect to the slide rail 2ks. The coupling and uncoupling takes place automatically at a predetermined door opening angle. The auxiliary drive 2 is coupled with its slide arm 2ka into the slide 2ks in an area of small door opening angles, namely during the closing process in the area between the predetermined door opening angle in which the automatic coupling takes place up to the closed position of the door and during the opening process also in this door opening angle range between the closed position of the door and the predetermined door opening angle at which the automatic disengagement takes place. The automatic engagement and disengagement takes place at the identical, predetermined door opening angle. The drive unit 2g of the auxiliary drive 2 is in the exemplary embodiment Figures 13.1 to 13.3 designed as a gas pressure spring 2gd, the output 2aa of which is designed as a piston rod which is drive-connected to the sliding arm linkage of the power transmission device, ie to the sliding arm 2ka. The gas pressure spring 2gd is loaded in the coupled position of the power transmission device during the opening process and during the Unload closing process. The auxiliary drive 2 acts as a support for the main drive 1 in the coupled position of the power transmission device.

In all the exemplary embodiments shown in the figures, the drive unit 1g of the main drive 1 is mounted on the sash side and the slide 1ks of the power transmission device of the main drive 1 is mounted on the frame side, in each case in the area of the upper horizontal frame spar of the door frame R. An essential aspect here is that the frame side mounted Components of the auxiliary drive 2 are each mounted in such a way that a frame-side assembly space M remains free for the assembly of the additional functional components of the main drive 1 to be mounted on the frame side.

The additional functional components of the main drive 1 to be mounted on the frame side can be an electrical locking device which interacts with the slide 1kag of the main drive, which is guided in the slide 1ks, in order to fix the door leaf in an electrically switched open position or to release it to close, as is known per se . The additional functional component can also be a smoke alarm, for example a smoke alarm, which interacts with the electrical locking device in order to trigger it in the event of a fire. The smoke detector can also be installed alone as an additional component in the installation space. A closing sequence control device, ie preferably a transmission device for the closing sequence control, can also be used as an additional component. The latter applies to designs of the door drive 10 according to the invention mounted on double-leaf doors. The transmission device of the closing sequence control can be controlled by the slider 1kag and / or the slide arm 1ka of the power transmission device of the main drive 1. It can be a transmission device designed as a lifting or pull rod or flexible train, which interacts with its end on the stationary leaf side with the slider 1kag of the main drive 1 and with its end on the active leaf side cooperates with a blocking device of the active leaf in order to control the active leaf in such a way that the active leaf can only get into the closed position when the passive leaf is closed. Such closing sequence control devices with such transmission devices are known as such.

The assembly space M for the arrangement and assembly and accommodation of the additional components is formed in the above-described exemplary embodiments of the figures in that in the extension line that is aligned with the movement path of the slide 1kag of the main drive 1 guided in the slide rail 1ks or at least directly adjoins this and directly extended, the components of the auxiliary drive 2 mounted on the frame side do not intervene. The frame-side components of the auxiliary drive are preferably mounted in a plane that lies outside the named extension line. In the specific embodiments shown, the frame-side components of the auxiliary drive are arranged in a plane on the front side of the slide rail 2ks, i.e. in a plane which lies on the front side in front of the movement path of the slider 1kag.

In the embodiment of Figures 10.1 to 10.7 These frame-side components of the auxiliary drive, which are located outside the assembly space M, are the drive unit 2g of the auxiliary drive 2 and the coupling device 20k including the coupling lever 20ke. The The pivot bearing of the coupling lever 20ke is on the underside of the cover in a position which is at the front in front of the movement path of the slider 1kag. The pivot plane of the coupling lever 20ke lies between the movement path of the slider 1kag and between the pivot plane of the slide arm 1ka. In the coupling position, the coupling lever 20ke rotates counterclockwise and comes into engagement with the driver 1km arranged on the underside of the sliding arm 1ka. The assembly space M for the entire additional functional components is in the extension of the movement path of the slider 1kag, which extends in the direction away from the door hinges and away from the movement path of the slider 1kag. No frame-side component of the auxiliary drive 2 engages in this area, so that this space is available as an assembly space M for the additional functional components mentioned. The delimitation of the slide rail 1ks at its end remote from the door hinge is designed so that it can be broken through or removed to form the assembly space M so that it does not obstruct the assembly space M. In addition, a mounting space M is also designed in a corresponding manner at the end of the slide rail 1ks near the door hinge, e.g. to accommodate an electrical or mechanical locking device with which the door can be locked in the open position by interacting with the slider 1kag of the main drive 1.

In the embodiment of Figures 11.1 to 11.3 is the assembly space M in a corresponding manner as in the embodiment of FIG Figures 10.1 to 10.7 available, since the frame-side components of the auxiliary drive 2, ie the drive unit 2g of the auxiliary drive 2 and the coupling device 20k including the coupling lever 20ke are arranged and mounted in the same way. In this embodiment, the acts The only difference is that the clutch lever 20ke is directly related to the slider 1kag of the main drive 1. The driver 1km, on which the coupling lever 20ke comes into engagement with the slider 1kag with its catch recess in the coupling position, is designed as the bearing shaft of the slider 1kag, with which the slider 1kag is rotatably connected to the connection end of the sliding arm 1ka. The swivel plane of the clutch lever 20ke is also here between the swivel plane of the slide arm 1ka and the path of movement of the slider 1kag, so that engagement in the clutch position on the driver 1km is possible without the clutch lever 20ke colliding with the slide arm 1ka or the slider 1kag. The assembly space M for the additional functional components in this embodiment is designed in the same way as in the previously explained embodiment, since in the same way no frame-side components of the auxiliary drive engage in the extension space in the movement path of the slider 1kag at the end of the slide rail 1ks remote from the door hinges B. In addition, in this exemplary embodiment, too, a mounting space M can be formed at the end of the slide rail 1ks near the belt, for example likewise for receiving a mechanical or electrical locking device in order to lock the door in the open position.

In the embodiment of Figures 12.1 to 12.4 the drive unit 2g of the auxiliary drive 2 with the coupling device with coupling lever 20ke and control lever 20ks is also mounted in a plane which is offset parallel to the movement path of the slider 1kag. In this case, both the control lever 20ks and the clutch lever 20ke then interact with the slider 1kag. With their end of action they each engage in the movement path of the slider 1kag in order to interact with the slider 1kag of the coupling position. However, it remains the same as those described above Embodiments of an assembly space M, which extends away from the hinges B in the horizontal direction on the door frame R in alignment with the line of movement of the slider 1kag. No components of the auxiliary drive 2 mounted on the frame protrude in this assembly space M. The clutch lever 20ke and the control lever 20ks also do not intervene in this space, but instead they interact with the slider 1kag in a plane offset parallel to the front. As in the previous exemplary embodiments, a mounting space M can also be formed in this exemplary embodiment at the end of the slide rail 1ks near the door hinge to accommodate corresponding additional components.

The one in the Figures 13.1 to 13.3 The illustrated embodiment likewise does not engage the components of the auxiliary drive 2 mounted on the frame side in the extension of the line of movement of the slider 1kag of the main drive 1 guided in the slide rail 1ks. In this case, the auxiliary drive 2 is formed by a drive unit 2g mounted on the wing side with a slide arm slide rail linkage as a power transmission device. The slide rail 2ks of this power transmission device of the auxiliary drive 2 is mounted horizontally aligned with the frame R and forms the component of the auxiliary drive mounted on the frame side. This is outside of the aforementioned assembly space M for the assembly of the additional functional components, since the slide rail 2ks of the auxiliary drive 2 is mounted in a plane that is on the front side of the slide rail 1ks of the main drive 1 and thus the front side towards the front relative to the movement path of the slider 1kag of the Main drive 1 is offset. In this exemplary embodiment, too, a mounting space M can be formed at the end of the slide rail 1ks near the belt.
