Description

Door drive device with a disengageable linkage

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

Door operators with disengageable force transmitting linkages are already known, e.g. from the documents DE 212280 A; DE 1 262 533 B; DE 1 901 664 A, EP 2 392 757 A1, JP 2010-1 12052 and JP 2010-236186 A.

The documents DE 1 262 533 B and DE 1 901 664 A describe door drives in which the force-transmitting linkage occupies a dead center position in the disengaged position. The dead center is at a predetermined

Door opening angle when engaging / disengaging respectively automatically switched on or off due to the respective angular position of the linkage at the relevant door opening position. The documents DE 212280 A, EP 2 392 757 A1, JP 2010-112052 and JP 2010-236186 A describe door drives in which the force-transmitting linkage is held in the disengaged position by a mechanical stop device. The mechanical stop device is automatically switched on or off during the disengaging / engagement process.

Disadvantage of the known systems is that the force-transmitting linkage is accessible in the disengaged position for manipulation. The invention has for its object to provide a door drive device with on / auskuppelbarem linkage, which has increased security against manipulation.

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

It is a door drive device for a door of a building with a door pivotally mounted in a fixed door frame about a vertical door axis pivotally. The drive device comprises a drive for

Actuation of the door leaf in terms of closing movement and / or

Opening movement and / or closing damping and / or opening damping.

The drive has a drive unit and a power transmission device, which has a linkage and a rod-end bearing. The

Power transmission device is connected to the drive unit during the

Opening and closing process automatically on and disengageable. The coupling and uncoupling point is formed between the linkage and the linkage bearing or between the linkage and the drive unit. The drive further comprises a holding device for the disengaged linkage, which is dependent on the open position of the door forcibly in a blocking position and a release position switchable such that the

Holding device holds in its blocking position the disengaged linkage in a predetermined linkage position and does not hold in its release position the disengaged linkage in this linkage position.

Essential for the solution of the problem is in the subject of

Patent claim 1, that is provided that the holding device is designed as a composite holding device, which is a first in

Has blocking position and release position switchable holding device and a second in the blocking position and release position switchable holding device. The solution thus provides that for the fixation of the disengaged

Linkage not only a holding device, as known per se, but two holding devices are provided. This means that manipulation is difficult. The second holding device thus represents an additional holding device, so at least two on the disengaged linkage

Holding devices act. A manipulation of the disengaged

Linkage is difficult because not only the effect of a single holding device must be eliminated for a manipulation.

An essential aspect of preferred embodiments is when it is provided that the first holding device and the second holding device are formed independently switchable by at least one of the two Holding devices can be switched independently of the other holding device. Due to the independence of the switchability of the two holding devices is made difficult by a manipulation attack the disengaged linkage is adjusted such that the subsequent engagement process is compromised. In preferred embodiments, it may be provided that both holding devices are each independently switchable, ie that in a circuit of a holding device, the other holding device is not in each case dependent on, ie not necessarily thereby also switched. However, it may also be provided in other embodiments, that the first holding device each with a circuit of the second

Holding device is connected, i. so depending on the first

Holding device is also switched, but vice versa not, that is, with the circuit of the first holding means is not dependent on each, i. not necessarily so that the second holding device is switched. The term "switching the holding device" is understood that the holding device is switched from the release position to the blocking position and / or that the holding device from the blocking position in the

Release position is switched. It is in this context

Release is available. However, embodiments are also possible in which the independence of the circuit is present only from the release position in the blocking position. In addition, embodiments are possible in which the independence of the circuit is present both from the release position into the blocking position and from the blocking position to the release position. Preferred embodiments provide that the holding device is switched to the blocking position when the first holding device or the second holding device is switched in blocking position or when the first holding device and the second holding device are switched or switched simultaneously or in a predetermined order in blocking position. Alternatively or additionally, these embodiments may also provide that the

Holding device is switched in the release position or will, if the first holding device and the second holding device are switched or switched simultaneously or in a predetermined order in the release position.

Embodiments are particularly preferred in which it is provided that the first holding device is designed as a dead center position device and / or as a stop device and / or as a latching device and / or as a magnetic device. The dead center position device can be realized in that the disengaged power transmission linkage forms a toggle lever constellation. In such a device, the dead center position device may be formed by a corresponding arrangement of a plurality of joints along a substantially straight line.

Embodiments are also possible in a corresponding manner, which provide that the second holding device is designed as a dead center position device and / or as a mechanical stop device and / or as a latching device and / or as a magnetic device.

Particularly preferred embodiments are those in which the circuit of

Holding device during the opening process and / or during the closing process of the door is done automatically. In that regard, for example, embodiments are preferred which provide in that the first holding device is designed as a dead center position device in that the detachable / detachable linkage, in conjunction with the output of the drive unit, forms a toggle device which can be automatically switched as a function of the angular position of the on / off linkage.

Release devices in the release position is switchable. In that the holding device has at least two release devices, i. several

Release devices, which are used for switching the holding device in must be operated certain way, an increased security against manipulation is obtained. The term "release device" is understood to mean an actuating device of the holding device, by means of which

Actuation of the holding device from the blocking position is switched into the release Steliung. It is essential that a plurality of such actuators are provided, which are preferably operated separately and independently of each other, to obtain the release position of the holding device. In the opening and closing operation, the actuation of the

Release device each automatically and / or forcibly, preferably by the movement of the door and / or by the traversed during the movement of the door door positions. This automatic and / or forced operation can be done by certain components of the door drive device and / or through the door itself. Corresponding switch and / or sensor devices can interact with moving components. The switching of the holding device then takes place during operation in each case by the corresponding automatic and / or automatic operation of the respective

Release devices. The holding device is thus protected from manipulation by arbitrary actuation. For switching the holding device from the blocking position in the

Release position may arrive at the switching times, ie at the times of actuation of the release devices, namely on the actuation time of the first release device and the actuation time of the second release device. The actuation times may be, for example, in a particular order or the actuation times may be simultaneously. Additionally or alternatively, however, it may also depend on a temporal relation of the actuation states of the release devices, for example, that the respective duration of the actuation of the Release devices may be different in length and / or overlap in time or simultaneously overlapping or successively in a particular order over a particular duration. It can be provided that a release device as part of

Door drive device and / or by the drive unit and / or by the power transmission an improper manual

Operation is prevented from outside and / or obstructively covered. There are particularly advantageous embodiments of door drive devices possible, which have a main drive and an auxiliary drive. Of the

Main drive is permanently coupled during the entire opening process and during the entire closing process, i. he instructs

Power transmission linkage, which does not disengage and engage during operation of the door. Only the auxiliary drive has a on and / or close on and disengageable linkage. The auxiliary drive is preferably designed as a door drive device, as discussed above, in particular with a holding device for the disengaged linkage, wherein the holding device depending on the open position of the door is forcibly switchable in a blocking position and a release position such that the holding device disengaged in its blocking position

Linkage holds in a predetermined linkage position and in her

Release position the disengaged linkage does not hold in this linkage position.

The holding device may be formed as a composite holding device with a first and a second holding device, such as

previously discussed. The holding device can in particular also a

Release device as part of the holding device or connected to the holding device, optionally with a first release device of the first holding device and a second release device of the second holding device, as discussed above.

In the door drive device with main drive and auxiliary drive can be provided with particular advantage that the linkage of the main drive as a sliding arm and the linkage bearing of the main drive as a slide

In particularly preferred embodiments, the holding device, as already mentioned, is formed as a composite holding device from a first holding device and a second holding device. In the concrete preferred embodiments, the first holding device is provided by a dead center position device of the preferably provided

Toggle mechanism of the linkage of the auxiliary drive formed. The

Dead center position is in each case at a predetermined angular position of the Linkage in the on / off position automatically due to the respective angular position of the linkage. The release takes place through

Change in the angular position of the linkage, i. e.g. intended when immersing the free end of the disengaged angle arm in the associated slide rail. The free end of the disengaged angle arm thus forms the release device of this first holding device, because when the free end is pivoted from the angular position by attacking the free end, the release of this first holding device takes place. The second holding device in the concrete versions can

preferably formed by a locking arm of an anchor device. The locking arm holds the disengaged linkage of Hiifsantriebs in the predetermined angular position, which corresponds to the angular position of the linkage during engagement / disengagement. The release of this second holding device is effected by pivoting the locking arm. In a concrete embodiment of the locking arm is designed as a locking lever, with a control lever

cooperates, which is actuated by the sliding arm of the main drive. Thus, the control lever is the release device of the locking arm of the second holding device.

In preferred embodiments, a predetermined order for the

Release of the holding devices required. In the concrete embodiment described, the blocking arm of the stop device must first be released and thereafter, or at least at the same time, the dead center position device of the toggle configuration of the angle arm be released by

Actuation of the free end of the disengaged linkage. As far as the drive unit of the main drive is concerned:

The drive unit of the main drive can be designed as a spring store, which is forcibly charged during the opening process and then drives under discharge the door to close. But they are too

Possible embodiments in which the drive unit is designed as a spring store, which is charged when closing and then under

Discharge drives the door to open.

The drive unit may comprise a damping device for damping the closing movement and / or the opening movement, preferably a hydraulic damping device. The charging of the spring accumulator can be done forcibly in the case of the closing drive as well as in the case of the opening drive when the door is manually operated, i. in the case of

Closing drive forcibly occur during the opening process and in the case of the opening drive forcibly carried out during the closing process. But it can also be provided an electric motor for charging the spring accumulator and it is also possible embodiments in which a preferably electrically switchable locking device is provided with which the spring accumulator is kept in the charged state, with appropriate circuit of the locking device during the closing process and / or to be switched on during the opening process to close or to open or to serve as an emergency or emergency opener. The locking device can also be formed mechanically switchable, for example, forcibly automatically switching. Alternatively or in addition to the spring accumulator, the drive unit of the main drive may also have an electromechanical motor with which the opening operation and / or the closing operation is carried out by an electric motor. As regards the drive unit of the auxiliary drive:

The drive unit of the auxiliary drive can be designed as a spring store, which is forcibly charged during the opening process and then drives the door to close under discharge. But they are too

Versions possible in which the spring accumulator when closing

is charged and then drives under discharge the door to open.

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

The charging of the spring accumulator may occur during manual operation of the door, i. when opening or closing done forcibly. However, it can also be provided an electric motor for electromechanical charging of the spring accumulator.

There are also embodiments in which a preferably electrically switchable locking device is provided with which the spring accumulator is kept in the charged state to be switched on with appropriate circuit of the locking device during closing and / or opening operation for closing or opening or as Emergency Closer or Emergency Opener to serve. The locking device may also be formed mechanically switchable, for example, forcibly automatically switching approximately in Connection with coupling / disengaging the boom or when reaching a certain door opening angle.

Alternatively, or in addition to the spring accumulator, the drive unit may also have an electromechanical motor with which the

Opening process and / or the closing process is carried out by an electric motor.

The auxiliary drive is provided as a supplement to the main drive. Of the

Auxiliary drive and the main drive are advantageously as a separate

Drive devices formed in combination with each other

interact. They are preferably mounted side by side on the door. The components of the auxiliary drive and main drive are preferably separate units, but may be interconnected, e.g. by mutual attachment and / or connection points and / or by common storage facilities or covering facilities.

The drive device of the auxiliary drive is composed of a drive unit and a power transmission device. Likewise, the drive unit of the main drive is composed of a drive unit and a power transmission device.

Significant advantages arise when the auxiliary drive is designed so that the power transmission device has a coupling / uncoupling point, so that it is possible the auxiliary drive only in a certain

Door opening area during closing and / or the opening process zuzuschalten only to assist in this particular area the main drive. As far as the power transmission equipment is concerned:

Each drive unit is in the preferred embodiments of

Drive device according to the invention assigned to a power transmission device. The power transmission device may be composed of a linkage and a rod stock. The linkage has a

Connection end for connection to the output of the assigned

Drive unit on. At the end remote from the drive unit, the linkage is mounted in the rod stock. The linkage can be designed as a sliding arm or as a scissors linkage. The rod bearing can be designed as a slide rail or pivot bearing. The linkage forms the force-transmitting connection of the power transmission device. It connects the output of the drive unit with the rod end bearing in a force-transmitting manner.

It should be noted that the linkage in addition to the connectable to the output of the drive unit terminal end of the linkage can still have a further support. In this further support may be the support in a bearing which is formed stationary with the support of the drive unit. For example, such embodiments are possible with a sliding arm which engages with its connecting end to a linear output of the drive unit and having an angularly protruding further connection end to support itself in a bearing which is stationary with a bearing in which the

Drive unit supported. The power transmission device serves to transmit the driving forces between the door leaf and the frame. If the drive unit is mounted on the wing, the linkage bearing is to be mounted on the frame. If the drive unit is mounted on the frame, the rod assembly is to be mounted on the wing. The mounting arrangement on the frame and wings can be used for the

Main drive can be selected the same as for the auxiliary drive. The arrangement may be such that the drive units both on the wing and the

Linkage bearings are both mounted on the frame or vice versa, that the drive units are both mounted on the frame and the rod bearings both on the wing. However, the arrangement can also be chosen differently from one another, i. the drive unit of the auxiliary drive on the wing and the

Drive unit of the main drive on the frame and the rod assembly of the auxiliary drive on the frame and the rod end main drive on the wing or vice versa, namely the drive unit of the auxiliary drive on the frame and the drive unit of the main drive on the wing and the rod assembly of the auxiliary drive on the wing and the linkage main drive on the frame.

As far as the terms sliding arm and slide rail are concerned, it should be noted that the free end of the sliding arm is guided in the slide rail and does not necessarily have to slide in the physical sense. In any case, the

Slide rail but a guideway, in which the free end of the sliding arm is guided. The free end may be formed as a sliding block, which is actually slidably guided in the guideway in the physical sense. However, the slider may also be a roller which is guided in a rolling manner in the guide track of the slide rail. The slider may also be a pinion, which is guided in a meshing manner in the guideway of the slide rail on a toothing or the like. Sliders are therefore not necessarily understood as a sliding element that slides in the physical sense. In the sliding arm but it is always a force-transmitting guide arm and the guide rail to a guide rail, wherein the guide arm with its free end in the guideway of

Guide rail is guided.

The guideway of the guide rail may be a linear guideway. However, embodiments are also possible in which the guideway is formed as a non-linear curved path.

Drive unit stationary output bearing. The connection of the angle arm 2ka in the region of its angle vertex corner 2kae at the output end of the piston rod 2gks to form the connection joint 2gg forms the connection of the angle lever 2ka at the output end of the drive unit 2g. The free end of the long leg 2kaa of the angle lever 2ka is designed as a slider 2kag and is in the frame side mounted slide 2ks of the door puller 2 automatically switched on and disengaged. In the engaged position in the slide rail 2ks, the angle lever 2ka forms a force-transmitting linkage with the slide rail 2ks as a special Gleitarmgestänge with slide rail. The automatic engagement and disengagement takes place when the door leaf reaches a predetermined door opening angle. This predetermined

Door opening angle is in the illustrated embodiment at about 30 ° door opening angle. When opening and closing in the

Range of door opening angles between 30 ° and 0 °, i. by doing

Partial opening area between a door opening of 30 ° and the closed position of the door, the angle lever 2ka is guided as a force-transmitting sliding arm with its slider 2kag engaging in the slide rail 2ks. As best seen in the illustration in Figures 2.3 and 2.4 and Figures 3.3 and 3.4, forms the pivotally mounted piston-cylinder unit 2gkz with its piston rod 2gks together with the also pivotally mounted angle lever 2ka in conjunction with the

Articulated in 2gg a toggle. The connecting joint 2gg forms the knee joint. Because of this knee joint configuration, the

Angle lever 2ka take two dead center positions. The one dead center position is the on / off position shown in Figures 3.3 and 3.4. In this position, the Geienkpunkte the camps 2gs, 2kas, 2gg are in a line. The other dead center position of the angle lever 2ka is the closing end position in which the angle lever engages in the slide rail 2ks and assumes its right in Fig. 1 end position in which the door is closed. This dead center position is shown in Figures 2.3 and 2.4. In this position, the hinge points of the bearings are 2gs, 2gg, 2kag in a line. The hinge point 2kag is formed by the sliding in this position in the slide 2ks engaging slider of the sliding arm 2ka. In both dead center positions is the

Sliding arm 2ka constantly locked in the associated angular position and thus also determined the output of the connected drive unit 2g accordingly.

In the first dead center position, i. in the on / off position of the slide arm 2ka, the closing spring 2gf of the piston-and-cylinder unit 2gkz is more cocked than in the second dead center position, i.e., in the second position. in the end position, which is associated with the closed position of the door. By the first dead center of the sliding arm 2ka is in the disengaged position, the voltage of

Closing spring, i. the charge that the shutter spring in the input /

Disengaged position held. As soon as the sliding arm 2ka is engaged in the slide rail 2ks, the first dead center position is automatically released during the closing operation, by changing the angular position of the sliding arm. In this case, the sliding arm 2ka is driven by the action of the closing spring 2gf in the closing direction while reducing the bias of the closing spring 2gf. The sliding arm 2ga rotates in Fig. 3.2 in a clockwise direction 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 at the

Opening movement of the door charged as long as the sliding arm 2ga is guided in the slide rail 2ks engaged.

It is essential in the illustrated embodiment that the

Sliding arm door closer 1 closer to the door axis, i. arranged closer to the door hinges than the auxiliary drive 2. The sliding arm 1 ka des

Gleitarmtürschließers 1 remains permanently during the entire opening and closing process with the slide rail 1 ks coupled and guided therein. The slider at the free end of the sliding arm 1 ka runs in the slide rail 1 ks when closing in Fig. 1 to the right and when opening in Fig. 1 to the left. In contrast, as already explained above, the force-transmitting linkage 2k of the auxiliary drive 2 is designed so that the sliding arm 2ka with the slide rail 2ks at a predetermined door opening angle during the closing and

Opening process is automatically switched on and disengaged. The inputs and

Disengaging takes place such that the angle lever acting as sliding arm 2ka is coupled with its free end exclusively at door opening angles in the range between this predetermined door opening angle and the closed position with the slide rail 2ks, i. in the slide rail in this

Door opening angle range engages and during closing and the

Opening process performed only in this angular range in the guide rail 1 ks is. In the area larger door opening angle, ie from the predetermined

Door opening angle is the sliding arm 2ka with its free end from the

Slide rail 2ks disengaged, i. not connected to the slide rail and not guided in the slide rail.

For engagement and disengagement of the slider 2kag formed at the free end of the slide arm 2ka, the slide rail 2ks has an opening 2k0 on the front side. This opening opens via an inlet slope into a slide within the slide rail 2ks, in which the slider 2kag after engaging in the

Closing movement and the return movement is guided in the opening direction. This slideway in the horizontally mounted slide 2ks may be formed linear or non-linear depending on the embodiment of the auxiliary drive 2. The engagement and disengagement of the slide arm 2ks is, as discussed, automatic in the opening and closing operation.

The operation of the drive device:

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

From the closed position of the door shown in Figure 1, the door 3 can be opened by the door 3f is manually pivoted in the opening direction. Here, the Türschließergleitarm 1ka rotates with the rotatably connected

Door closer shaft 1w about the axis of rotation of the door closer shaft 1w in Figure 1 in the counterclockwise direction. The sliding arm 1 ka is thereby guided with its designed as a slider free end in the slide rail 1 ks such that the free end of the slide arm 1ka runs in the illustration in Fig. 1 to the left. During this opening movement also the toggle-like trained sliding arm 2ka of the auxiliary drive 2 rotates, in a corresponding manner, by the free end of the sliding arm 2ka runs with its free end in the slide rail 2ks in the illustration in the figures to the left. The toggle-like

Gleitarmgestänge, which is composed of the Winkelarm 2ka and the piston rod 2gks the piston-cylinder unit 2gkz, in this case rotates in a corresponding manner about the axis of the wing-mounted pivot bearing 2gs. Essential in the illustrated embodiment, however, is that this toggle type linkage, i. the free end of the Winkelgleitarms 2ka, automatically disengages from the slide rail 2ks, as soon as from the closed position of this predetermined door opening angle is reached. In the illustrated

Embodiment, this is done at a door opening angle of about 30 °. In this angular position, the knee-lever-like linkage 2k reaches its first dead center position. When disengaging from the slide 2ks, the angle arm 2ka remains in the angular position of this Totpunktsteliung. The angle arm is quasi locked in this position against further rotation and moves in this angular position in the further opening of the door from the front opening 2kö of the slide 2ks. In the dead center position, the angle arm 2ka remains quasi locked. The piston rod of the piston-cylinder device with the closing spring remains locked in this position as well.

If the door is to be moved from the open position back into the closed position, the closing movement takes place with disengaged angle 2ka arm up to the predetermined Einkupplungswinkelstellung. The angle arm 2ka is therefore unchanged in the dead center of Figures 3.1 and 3.4, they at

Disengaging has taken. As soon as the door leaf has now reached the predetermined door opening angle of approximately 30 ° during the closing operation, the angle arm 2ka fixed in this coupling / disengaging angular position comes with it free end, ie the slider 2kag, again for engaging in the slide 2ks. The free end of the sliding arm 2ka with the slider 2kag moves into the opening of the slide rail 2ks. Upon further closing of the door, the angle arm 2ka is engaged with its free end in the slide rail 2ks and runs in the illustration in Fig. 1 in the slide of the slide 2ks to the right through the slide 2ks out. The toggle lever configuration has in this case automatically released the engagement / disengagement detent position under the action of the slide rail guide by changing the angular position of the free end of the angle arm 2ka. As soon as this dead center position is released, the closing spring held tight as it now acts under discharge as a rotary drive of the angle lever in the closing direction. That is, the closing process is then supported by the auxiliary drive 2. The toggle finally reaches in the

Closed position of the door shown in Fig. 1 second dead center. In this second dead center position, the toggle lever configuration locks in the relevant angular position. This dead center then remains up until the door is pivoted by manually pulling the door back into the open position. During this opening movement, the dead center position is automatically canceled by the pivoting of the angle arm 2ka and the closing spring is recharged.

Modified auxiliary drive

In the figures 4.1 to 4.3, an auxiliary drive 2 is shown, which, as in the embodiment of the preceding figures, a drive unit 2g having a piston rod 2gks, for example formed as a gas spring. The difference from the embodiments of the preceding figures is that the drive unit 2g is used for pressurization, ie the piston rod 2gks is when the door is opened by charging the Energy storage in the housing, ie inserted into the piston, so shortened. When closing the door, the piston rod is pushed out with discharge of the energy storage, ie extended. For this is the

Storage of the drive unit 2g compared to the embodiment of the preceding figures designed modified accordingly. In the case of Figures 4.1 to 4.3, the piston rod 2gks acts on a mounted on the bearing rack arm device with a connecting link 2kav, which is connected at one end to the piston rod 2gks and attacks with its other end to the angle arm 2ka and when opening the door to train is claimed when the piston rod 2gks is extended.

As can be seen from Figures 4.1 to 4.3, the drive unit 2g of the auxiliary drive 2 is mounted on a storage rack 2m, which is the same as in the embodiment described above with a wing-side mounting of the drive unit 2g to mount wing-mounted. The

Drive unit 2g is articulated with its cylinder-like housing in a arranged on the storage rack 2m pivot bearing 2kas. The

Output end of the piston rod 2gks is hinged to 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 to the articulated

Support the piston rod 2gks on. The sliding arm 2ka is also formed in this embodiment as an angle, in the illustrated case also as a right angle with a first and a second leg. As can be seen in FIG. 4.1, the first leg 2kaa is offset in height from the second leg 2kab. The first leg 2kaa points for this purpose

Crowning a height offset 2kah on, so that the first leg 2kaa is formed substantially L-shaped and from the apex end of the second leg 2kab is perpendicular to the top.

At the free end of the first leg 2kaa the slider 2kag is arranged. The second leg 2kab is formed as a bearing leg, which is mounted with its free end in the arranged on the bearing frame 2m pivot bearing 2kas. In the same pivot bearing 2kas is also the case of the

Drive unit 2g stored. The connecting link 2kav connects the pivot bearing 2gkg, in which the driven-side end of the piston rod 2gks is supported, to the bearing 2kas disposed at the apex of the angle arm 2ka, in which the connecting link 2kav has its one end in the

Spherical bearing 2gkg and with its other end in the crown bearing 2kas articulated. The height offset of the angle arm 2ka, i. the height offset of the lever arms 2kaa and 2kab to each other in the illustrated in Figures 5.1 and 5.2

Adjustable embodiment. This embodiment corresponds structurally and functionally to the exemplary embodiment of FIGS. 4.1 to 4.3. The adjustability of the height offset takes place, as can be seen from FIGS. 5.1 and 5.2, via a slot-type screw connection 2kj of the two arms 2kaa and 2kab. In the illustrated embodiment, two elongated holes are formed in the vertical set piece 2kah of the first arm 2kaa, into which

Engage fastening screws which are fixed in mounting holes of the second arm 2kab, for example by means of a screw with nuts. They form a height-adjustable adjustable clamping connection of the two arms 2kaa and 2kab to adjust the height offset fit to the height position of the drive unit 2g to the slide rail 2ks. Modified drive with mounting space M

The embodiment of Figures 6.1 to 6.3 shows a modification of the embodiment of the drive of the preceding figures. In the

Modification is also a composite drive 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 at the front side of the slide rail 1ks of the main drive 1, i. the slide of the slider 2 kag of the auxiliary drive 2 is in a plane which is front of the slide of the slider 1 kag of the main drive 1. As can be seen in FIGS. 6.1 to 6.3, the sliding track of the slider 2kag of the auxiliary drive 2 can overlap more or less with the sliding track of the slider 1kag of the main drive 1. It is essential, however, that the two slideways are offset from each other in parallel to the front side and thus do not interfere with each other. This offset from each other has the advantage that any additional components of the main drive 1, the conventional

Gleitarmantrieben are arranged in the slide rail of the drive, such. a locking device in the open position of the door, a smoke detector or double-leaf door closing sequence control components can continue to be arranged in a conventional manner in a mounting space in the slide 1ks or in an extension line of the slide of the slider 1kag this slide, since the slide 2ks of Auxiliary drive 2 is arranged outside this mounting space, ie leaves this mounting room empty.

Drive with tamper protection for the disengaged sliding arm of the

auxiliary drive In the figures 7.1 to 7.7 is an embodiment of a

Tamper protection device 5 is shown, which serves to fix the predetermined position of the disengaged power transmission of an auxiliary drive in an open position of the door leaf and thus against a

To protect manipulation. In the embodiment of Figures 7.1 to 7.7, such a manipulation protection device for the angle 2ka of the auxiliary drive 2 is provided. The structure of the overall drive is the same as shown in Figures 6.1 to 6.3. The manipulation protection device 5 in FIGS. 7.1 to 7.7 comprises a lever device with a control arm 5ka designed as a pressure arm and a blocking arm 5ks. The two arms are movably mounted on a guide and bearing plate 5f in the manner of pivoting arms. The plate 5f is on the hinge-side storage frame 2m of

Auxiliary drive 2 arranged. The storage rack 2m is connected on one side to the underside of the guide and bearing plate 5f. The guide and bearing plate 5f is perpendicular to the front side of the storage rack 2m. In the upper free area of the guide and bearing plate 5f opposite to the direction of the door opening is a fixed pivot 5kal. In this camp 5kal the control arm 5ka is pivotally mounted. The connection of the control arm 5ka with the pivot bearing 5kal is effected in a region between the two ends of the control arm 5ka relatively close to the end remote from the door leaf 1 of the control arm 5ka. This facing away from the door leaf 1 end of the control arm 5ka has a pivot bearing 5ksl, via which by means of a further axis of this end of the control arm 5ka with one end of the locking arm 5ks, which is guided in the direction of the door opening, is pivotally connected. In this case, the guide of the locking arm 5ks between a lower guide 5fu and an upper guide 5fo, which takes place in the direction

Door opening are on the front side on the guide and bearing plate 5f. The upper guide 5fo is located at the top of the guide plate 5f, the from the door leaf 1 shows away. The blocking arm 5ks will be between on the

Guide and bearing plate 5f located lower guide 5fu and the upper guide 5fo guided so that in an open position of the door 1, the free pointing in the direction of the door opening end of the locking arm 5ks with the

disengaged angle arm 2ka comes into contact. In the illustrated

Embodiment, the abutment position of the free end of the lock arm 5ks with the vertical offset piece 2kah of the arm 2kaa of the guide arm 2ka, i. in the area of the axis of the apex of arms 2kaa and 2kab. The free end of the locking arm 5ks has for this end one

Lock recess 5snr, which is formed so that it approximately complementary to the abutment edge of the set piece 2kah des

Guide arm 2ka is. This will change the position of the

Guide arm 2ka effectively prevented in an open position of the door leaf 1. So that in an open position of the door leaf 1 of the locking arm 5ks remains in this position to secure the predetermined position of the angle 2ka, the control arm is connected 5ka tamper protection device between its facing the door 1 free end and the pivot 5kal with one end of a return spring 5r. The other end of the

Return spring 5r is opposite to the direction of door opening with the

Guide and bearing plate 5f connected. The return spring 5r holds the control arm 5ka against a stop 5fa located on the guide and bearing plate 5f opposite to the direction of the door opening. The free end of the

Control arm 5ka is connected to a slider 5kag formed as a roller.

In the joint bearing 5ksl is located between the control arm 5ka and the blocking arm 5ks perpendicular to both arms standing vertically a vertical set piece 5kav. The set 5kav serves to the control arm 5ka with the slider 5kag to the level of Gieitarms 1 ka of the main drive 1 to position so that the slider 5kag can be detected during a closing operation of the door leaf 1 from the sliding arm 1 ka of the main drive 1 for actuating the control arm 5ka.

During a closing operation of the door leaf 1 ka of the main drive 1 on the slider 5kag the tamper protection device 5 with the placement of the slider 5kag on the sliding arm 1 ka exerted a pressure and so the control arm moves 5ka toward the door opening. The control arm 5ka then pulls over the pivot bearing 5ksl the locking arm 5ks opposite to the door opening direction and thus gives the guide arm 2ka of the auxiliary drive 2 free, so that the guide arm 2ka engages with the slider 2kag in the slide 2ks and the auxiliary drive 2 can be effective. The angle between the control arm 5ka and scissor-type connected in the joint bearing 5ksl

Locking arm 5ks is always less than 90 ° in the open position and closed position of the door leaf 1, in order to ensure a smooth operation of the locking arm 5ks.

During the opening operation of the door leaf 1, the return of the control arm 5ka takes place by the return spring 5r retracts the control arm 5ka up to the stop 5fa, so that the locking arm 5ks moves towards the door opening and finally the locking recess 5snr at the free end of

Locking arm 5ks at the complementary abutment edge on the set piece 2kav of the guide arm 2ka of the auxiliary drive 2 comes back into abutment. Thus, the manipulation protection device 5 is effective again after opening the door leaf 1 and the disengaged angle arm 2ka held in its angular position. The dead center device T of the toggle configuration K of the guide arm 2ka forms a first holding device of the disengaged guide arm 2ka. The anti-tamper device 5 with the lever device of locking lever 5ks and control lever 5ka forms a second holding device of the disengaged guide arm 2ka of the auxiliary drive 2. The two holding devices form a composite total holding device which hold the disengaged guide arm in the ready position. Only if both

Holding devices are released in the sense of elimination of the respective holding device, the release of standing in the standby position disengaged guide arm 2ka for guidance in the slide 2ks takes place. The release of the second holding device, i. of the locking lever 5ks is effected by actuation of the control lever 5ka by abutment of the sliding arm 1 ka of the main drive 1 upon reaching the predetermined door angle position. The release of the first holding device is accomplished by the operation of the free end of the guide arm 2ka, i. by pivoting the free end of its angular position. This is done as intended when immersing the slider 2kag in the opening 2kö the slide rail 2ks. Only when both holding devices are operated simultaneously or in a predetermined period of time in the sense release, the release of the total holding device and thus the release of disengaged takes place

Guide arm 2ka.

In the illustrated embodiment, the required switching sequence is such that first the release of the locking lever must be 5ks and then or at least simultaneously the dead center position device T of

Toggle configuration K by pressing the free end of the

disengaged Winkelarms 2ka must be released. The

Release means of the composite holding device are so arranged that they are not readily accessible from the outside for improper manipulation. This is done by a

Cover panel and on the other hand, that the various components of the drive are arranged nested, so that improper access is difficult. The cover panel may be formed so that it covers the respective release device separately, in the case shown, however, the Abdeckblende is formed as a common Abdeckblende covering at least all wing side mounted components of the auxiliary drive 2 or in particular as a common Abdeckblende the

wing-side components of the auxiliary drive 2 and the main drive 1, as they as a preferably hood-shaped cover 3fh to the

Embodiment of Figures 1 to 4 is described in more detail.

In the figures 8.1 to 8.3 is a second embodiment of a

Tamper protection device 5 shown. The

In the illustrated embodiment, it is an auxiliary drive of the structure, as shown in Figures 4.1 to 4.3 and therefore also in the drive of the figures in the auxiliary drive 7.1 to 7.7 is provided. To the predetermined position of the disengaged angle arm 2ka in the

Open position of the door leaf 1 to fix, is at the

Tamper protection device 5 in Figures 8.1 to 8.3 attached to the wing fixed to be mounted storage rack 2m of the auxiliary drive 2 on the right in the figures on the front side facing the door opening, a first permanent magnet 81. Furthermore, a second permanent magnet 82 is mounted on the surface of the vertical set piece 2kah of the angle arm 2ka, which faces the end face of the storage rack 2m. Here are the first Permanent magnet 81 and the second permanent magnet 82 to each other so positioned that the first permanent magnet 81 is disposed in the plane of movement of the permanent magnet 82. The magnetic poles of the two permanent magnets 81 and 82 are mutually formed so as to exert an attracting effect on each other when the angle arm 2ka is disposed with its permanent magnet 82 in a predetermined position near the permanent magnet 81 mounted on the support frame 2m. In Figure 8.2 the relevant position is shown in which the attractive effect exists. With an open position of the door leaf 1, the disengaged angle arm 2ka with the slider 2kag is positioned so that during a closing operation of the door leaf 1 the slider 2kag engages in any case in the opening of the guideway of the guide rail 2ks. In this position, the angle arm 2ka is in its disengaged due to its toggle configuration

Dead center. In this case, the angle arm 2ka by the magnetic

Attraction of the two permanent magnets 81 and 82 additionally fixed. The dead center device T of the toggle configuration K of the guide arm 2ka forms a first holding device. The magnetically acting device with the magnets 81 and 82 forms a second holding means of the guide arm 2ka in its disengaged position.

During the closing operation of the door leaf at a predetermined door opening angle just before the closing position of the door, the slider 2kag of the angle arm 2ka engages in the opening 2kö of the guide rail of the guide rail 2ks. In this case, the angle arm 2ka overcomes the dead center of the angle arm designed as a toggle lever and at the same time separates the first Permanent magnet 81 of the second permanent magnet 82 and continues running on the slider 2kag in the guideway of the slide rail 2ks. The activation of the magnetic lock of the angle arm takes place during

Disengaging automatically, as follows: During the opening process of the

Door leaf from the closed position of the door is effected by the pivoting movement of the Winkelarms 2KA an approximation of the Winkelarm arranged permanent magnet 82 to the rack-permanent magnet 81. Immediately after disengaging the Winkelarms 2ka from the slide 2ks then takes place the contact of the permanent magnets 81 and 82 and due to Toggle configuration of the guide arm 2ka is carried out by the formation of its dead center.

Embodiments are possible in which the sliding arm 2ka of the

Auxiliary drive 2 is not designed as an arm which forms a toggle configuration with dead center, but is held exclusively by a magnet device in the predetermined angular position with disengaged sliding arm or by the magnet device and additionally another

Holding device, e.g. a lever device with control lever 5ka and

Lock lever 5ks, as shown in Figures 7.1 to 7.7.

It is also possible with respect to the embodiment in Figures 8.1 to 8.3 modified magnetic devices which, in contrast to the magnetic device of Figures 8.1 to 8.3 an electromagnet as a magnetic element 81 or 82, which cooperates with a ferromagnetic or permanent magnetic counter-element 82 and 81, respectively ,

Embodiments with electromagnets are particularly suitable for applications in which the electromagnetic element is to be mounted on the frame side, ie preferably in embodiments in which the with the Holding device to be fixed disengaged guide arm is mounted frame side.

In the second shown in Figures 9a-9c and 10th

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 Gleitarmtürschließer with a mounted on the wing F drive unit 1a and a

Power transmission device 1k as a slide rail linkage with a sliding arm 1 ka and a slide rail 1 ks. The sliding arm 1ka is rotatably coupled with a mounted in a housing of the drive unit 1g output shaft 1w and guided the frame fixed mounted slide ks. The main drive is intended in the illustrated embodiment as Gleitarmtürschließer with a drive unit 1g with closer spring and hydraulic

Damping device may be formed. The auxiliary drive of the second embodiment:

The auxiliary drive 2 is formed in the case shown from a drive unit 2g and a force-transmitting linkage 2k. The drive unit 2g is integrated in a slide 2ss and fixed in a fixed position. The

Slide rail 2ss connects to the slide rail 1 ks of the main drive 1. In the illustrated case, the two rails 1ks and 2ss are formed as sections of a common continuous slide rail. The drive unit 2g of the auxiliary drive integrated into the section 2ks of the slide rail includes a spring accumulator 2f or alternatively or additionally one

Electric motor. The output 2aa of the spring accumulator 2f or of the electric motor interacts with the slider 2kag guided in the slide rail 2ks. It is a slider at the free end of the sliding arm 2ka. The sliding arm 2ka is mounted with its bearing end in a wing side

Swivel bearing 2kd pivotally mounted and guided with its free end on the slider 2kag in the slide 2ss. The slider 2kag is integrated with the free end of the output 2aa of the slide 2ss

Drive unit 2g connected. The output 2aa is guided linearly movable in the slide 2ss along the guide rail of the rail. The glider 2kag is taken here. The slide 2ss forms with the

Drive unit 2g stationary output bearing.

The output 2aa is guided in the guideway of the slide rail and thus a linear output. In the illustrated embodiment, the guideway of the slide rail is linear and extends horizontally. It should be noted that the output 2a is also understood as a linear output, if the guide rail of the slide rail is designed as a non-linear curved path in a modified embodiment. It should also be noted that other modified versions are also understood as a linear drive, namely in which a transmission is connected between the primary output of the drive unit and the output 2aa guided in the guide rail of the slide rail. The primary output may be e.g. be designed as a rotary drive. It can be designed as a rotating threaded spindle, on the one

Threaded nut runs, which is linearly guided in the guideway and the

Slide arm 2ka eg by driving the slider 2kag drives. As can be seen from FIGS. 9b and 9c, the sliding arm 2ka of the

Auxiliary drive 2 with the drive unit 2g in the slide 2ks on and disengageable. The coupling / disengaging point is in the embodiment of Figures 9b, 9c between the free end of the sliding arm 2ka and guided in the slide rail 2ss output member 2aa of the mounted in the slide 2ss

Drive unit 2g, i. formed between the terminal end of the sliding arm 2ka and the output of the drive unit 2g.

The engagement and disengagement takes place automatically during the opening and closing process at a certain door opening angle. Fig. 9b shows the door position in the door opening angle, in which the closing operation, the coupling and the opening process, the disengaging. at

Door opening angles smaller than this off and Einkupplungswinkelstellung the sliding arm 2ka is engaged (see Fig. 9b and 9a). For door opening angles greater than the on / off angle position, the slide arm is disengaged (see Figure 9c). In disengaged position, the sliding arm 2ka remains in this

Embodiment of the linkage bearing, i. in the case shown in Fig. 9c on the wing-side pivot bearing 2d, in a locked angular position of the wing F projecting. The locking of the angular position can be done by a cooperating with the sliding latch. The

Locking device is formed in the pivot bearing 2kd. The locked

Angular position corresponds to the angular position of the sliding arm takes 2ka when engaging / disengaging, ie the angular position in Fig. 9b. While the sliding arm 2ka is disengaged, the spring accumulator 2f of the power plant 2g remains in the charged position, in which the decoupling is done. It is the charged position that the spring accumulator has acquired during the opening process with the sliding arm coupled in. For this finding of the

Spring accumulator is in the range of the drive unit 2g a

Locking device provided. It is turned on with the decoupling of the sliding arm 2ka and turned off releasing the spring accumulator with the Einkuppein the sliding arm 2ka.

The Einkupplungsvorgang between the free end of the sliding arm 2ka and guided in the slide 2ks slider 2kg takes place automatically when

Closing operation of the door in the predetermined door opening angle shown in Fig. 9b. The free end of the projecting in this Winkeistellung sliding arm 2ka moves with its slider 2kag in this door opening position in the

Slide rail 2ks, via an unspecified

Entry slope through a front opening of the slide rail 2ks and couples with the standing in waiting position as a slider

Output member 2aa on. With the coupling of the arranged in the slide rail is charged during the previous opening operation

Spring 2f forced unlocked. By discharging the spring accumulator 2f thus made, the slider 2aa is driven in the closing direction together with the slider 2kag and the slide arm 2ka coupled thereto. The coupled slider 2kag and 2aa are moved in the illustration in the figures to the right and the sliding arm 2ka to the pivot bearing 1kd in

Turned clockwise. This means that the door F is doing in

Closing direction is moved. He finally reaches the closed position, which is shown in Fig. 1a. In the closed position, the sliding arm again reaches a locking position in which he remains until the door to commit then is opened again. This is done manually by pivoting movement of the door leaf F in the opening direction.

At the opening movement of the door of the sliding arm 2ka in the

Representation in the figures around the pivot bearing 1 kd turned counterclockwise. The slider 2kag with the output slider 2aa is doing in

Opening direction moves, i. moved in the slide in the illustration in the figures to the left. Once the door is the predetermined

Door opening angle of the input and Auskoppeins, which is shown in Fig. 9b, achieved, takes place automatically disengaging the sliding arm 2ka. The disengaged

Sliding arm 2ka remains then determined in the predetermined angular position, which he occupies when decoupling protruding from the wing-side

Swivel bearing 1 kd. The output slider 2aa remains after disengaging the sliding arm 2ka in its position, which it has assumed when disengaging, determined by the aforementioned locking device. Due to this automatically occurring determination also remains connected to the output slider 2aa memory spring 2f, as long as the slide arm 2 is disengaged, in the charged state, the memory spring 2f by the

preceding opening operation has reached with engaged sliding arm 2ka.

The auxiliary drive 2 is thus charged in the opening operation, as long as the sliding arm 2ka is engaged, i. when opening the door 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 is in the last one Closing phase, ie at the end of the closing process until the door has reached the closed position.

10 shows a modified embodiment, which differs from the embodiment of FIGS. 9a-9b in that the input / output

Disengagement point of the sliding arm 2ka not between the output of the

Drive unit 2g and the terminal end of the sliding arm 2ka is formed, but in the area between the wing-mounted pivot bearing 1kd and the sliding arm 2ka in the region of the bearing end of the sliding arm. Also in this modified embodiment of the sliding arm remains 2ka, as long as it is decoupled, in the angular position which he had taken when disengaging. Again, a Feststeileinrichtung for the angular position of the disengaged sliding arm and a locking device for the charging of the accumulator spring 2f is provided. This determination can be made via the locking of the sliding arm 2ka in the predetermined angular position in the manner of a dead center position, i. In a similar manner as in the embodiment of Figures 1 to 4. This means that also in this embodiment, the accumulator spring 2f remains in the charged position, which they when disengaging the

Sliding arm 2ka had.

It is essential in those shown in Figures 9 and 10

Embodiments that the frame-mounted components of the main drive 1 and the auxiliary drive 2, i. the slide 1 ks of

Main drive 1 and the slide 2ss with the stored therein

Memory spring 2f by a common continuous frame-side

Cover 3rh are covered. The same applies to the wing-side components, ie the Antiebsgehäuse 1g of the main drive 1 and the pivot bearing 2kd of the force-transmitting linkage of the auxiliary drive 2nd Sie are covered by a common continuous cover 3fk (not shown in the figures).

Particularly advantageous is the common continuous wing-side

Mounting plate 3fm on which the drive unit 1 g of the main drive 1 and the rotary bearing 2kd of the auxiliary drive 2 are mounted. This mounting plate 3fm is bolted only in its band-near section in a standard hole pattern of the door leaf with the door leaf. Also for the assembly of the frame-side components can

common continuous frame-side mounting plate 3rm be provided.

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

In a modification of the embodiment in Figure 10, the

Drive unit also be arranged on the sliding arm 2ka or be integrated therein. At the free end of the sliding arm 2ka can over the

Drive unit 2g driven pinion to be arranged in the

Slide rail 2ss is guided, for example, meshing on a arranged in the slide rail 2ks rack. Also in the embodiments of Figures 9 and 10 and the modifications discussed the use of anti-tamper means with corresponding holding device is possible. It can here the
