Description

There are z. B. 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 designed as a scissor linkage device or a sliding arm slide rail device.

An electromechanical door drive, which is formed comparably from a drive unit and a corresponding power transmission device, is z. B. from the 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 sliding 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 pivot 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 latching action 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, the spring force of the closing spring may not be sufficient to close the door at the end of the closing process. H. it can happen that the door does not come into the closed position, the lock latch is not overpressured and the door leaf just leans against the frame before reaching the closed position.

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

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

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

• Entladung sodann die Tür zum Schließen antreibt. Es sind aber auch Ausführungen möglich, bei denen das Antriebsaggregat als Federspeicher ausgebildet ist, der beim Schließen aufgeladen wird und sodann unter Entladung die Tür zum Öffnen antreibt.

As for the main drive unit:

• The drive unit of the main drive can be designed as a spring accumulator, which is forcibly charged during the opening process and under

• Das Antriebsaggregat des Hilfsantriebs kann als Federspeicher ausgebildet sein, der beim Öffnungsvorgang zwangsweise aufgeladen wird und unter Entladung sodann die Tür zum Schließen antreibt. Es sind aber auch Ausführungen möglich, bei denen der Federspeicher beim Schließen aufgeladen wird und sodann unter Entladung die Tür zum Öffnen antreibt.

As for the drive unit of the auxiliary drive:

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

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

The spring energy store can be charged when the door is operated manually, ie when it is opened or closed. However, an electric motor can also be provided for electromechanical charging of the spring energy store.

Versions are also possible in which a preferably electrically switchable locking device is provided with which the spring accumulator is kept in the charged state in order to be switched on with appropriate switching of the locking device during the closing process and / or during the opening process for closing or opening or as To serve as an emergency closer or emergency opener.

• Jedem Antriebsaggregat ist bei den erfindungsgemäßen Antriebseinrichtung eine Kraftübertragungseinrichtung zugeordnet. Die Kraftübertragungseinrichtung kann sich aus einem Gestänge und einem Gestängelager zusammensetzen. Das Gestänge weist ein Anschlussende zum Anschluss an den Abtrieb des zugeordneten Antriebsaggregats auf. An dem vom Antriebsaggregat abgewandten Ende ist das Gestänge in dem Gestängelager gelagert. Das Gestänge kann als Gleitarm oder als Scherengestänge ausgebildet sein. Das Gestängelager kann als Gleitschiene oder Drehlager ausgebildet sein. Das Gestänge bildet die kraftübertragende Verbindung der Kraftübertragungseinrichtung. Sie verbindet den Abtrieb des Antriebsaggregats mit dem Gestängelager kraftübertragend.

As for the power transmission device:

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

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

The power transmission device is used to transmit the drive forces between the door leaf and the frame. When the drive unit is mounted on the sash, the rod bearing must be mounted on the frame. When the drive unit is mounted on the frame, the rod bearing must be mounted on the sash. The mounting arrangement on the frame and sash can be selected the same for the main drive as for the auxiliary drive. The arrangement can be such that the drive units are both mounted on the sash and the linkage bearings are both mounted on the frame or, conversely, that the drive units are both mounted on the frame and the linkage bearings are both mounted on the sash. The arrangement can, however, also be chosen differently from one another, i. H. the drive unit of the auxiliary drive on the wing and the drive unit of the main drive on the frame and the rod bearing of the auxiliary drive on the frame and the rod bearing of the main drive on the wing or vice versa, namely the drive unit of the auxiliary drive on the frame and the drive unit of the main drive on the wing and the rod bearing of the auxiliary drive on the wing and the main drive rod bearing on the frame.

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

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

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

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 designed as a sliding arm door closer 1 and an auxiliary drive 2 , which can be designed as a door puller and / or closing damper. This division into the main drive is essential 1 and auxiliary drive 2 , ie it is essential that the door closer device consists of a main drive 1 and an auxiliary drive 2 is composed. This composite door drive device is denoted in the figures with the reference number 10 and is in 1 on a door 3 assembled. By the door 3 is it how 1 shows to a swing door that has a door leaf 3f includes that over door hinges 3b in a fixed door frame 3r around a vertical door axis 3a is pivotably mounted. The door leaf 3f is designed as a pivoting stop wing in the case shown. In the case shown, the door drive device is designed as a device which is mounted on the door and rests on it. However, it should be expressly pointed out that the door drive device 10 this structure can also be designed as a door drive device to be installed concealed inside the door.

The main drive:

As the figures show, it includes the main drive 1 sliding arm door closers forming a drive unit 1g as a door closer unit in a door closer housing 1g is formed received and a power transmission device 1k . The force application device 1k consists of a linkage that acts as a sliding arm 1ka is formed, and a rod bearing that acts as a slide rail 1ks is trained. This power transmission device constructed in this way 1k is also referred to in practice as a force-transmitting slide rail linkage. The door closer housing 1g is in the case shown on the door leaf 3f assembled. In the door closer housing 1g the closer mechanism is included. 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 with a door closer shaft 1w effectively connected. The door closer shaft 1 is in the door closer housing 1g rotatably mounted. At the end of the door closer shaft protruding from the housing 1w is the sliding arm 1ka of the linkage 1k connected. In the case shown, this consists of the sliding arm 1ka and the slide rail 1ks . The sliding arm 1ka is a one-armed lever that connects to the output of the drive unit 1g , ie the door closer shaft 1w facing end is non-rotatably connected to this. This end of the sliding arm 1ka forms the connection end. With its other end is the sliding arm 1ka in the slide rail 1ks via a slider engaging in the guideway of the rail 1kag guided. The slide rail 1 ks is on the top horizontal spar of the fixed door frame 3r horizontally aligned fixed to the door frame. The sliding arm door closer 1 is in the illustrated case, as already mentioned, designed as an overlying sliding 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 is 1g in the upper area of the door leaf resting on the door leaf 3f and the slide rail 1ks mounted on top of the 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 separate from the main drive 1 forming slide arm door closer 1 is trained. It includes as a drive unit 2g a damped closing unit that rests on the door leaf 3f is mounted, relative to the main drive 1 remote from the door axis, ie 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 mounted in the upper area of the door leaf. The closing unit 2g forms, as I said, the drive unit of the auxiliary drive 2 . The aggregate 2g is designed as a spring accumulator with hydraulic damping device. In the case shown, it comprises a piston-cylinder unit 2gkz with a closer spring device 2gf cooperates. Let it be on the 2.3 and 2.4 and on the 3.3 and 3.4 referenced. The piston-cylinder unit shown 2gkz can be designed as a hydraulic damping device. Instead of the piston-cylinder unit shown 2gkz with closer spring 2gf however, a gas pressure spring can also be provided. The cylinder 2gz In the case shown, the piston-cylinder unit is in a pivot bearing that is fixed to the door leaf 2gs with a vertical swivel axis in the installation position that can be swiveled on the door leaf 3f stored. The piston 2gk is linearly displaceable in the cylinder. The piston 2gk is in the area of its free end section as a piston rod 2gks educated. 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 case shown 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 via a connecting joint 2gg with the output end of the piston rod 2gks of the auxiliary drive 2 connected. The joint axis of the connecting joint 2gg is vertical in the installation position, ie parallel to the pivot axis of the pivot bearing 2gs aligned over 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 at the outer vertex of the angle lever 2ka on. The angle lever 2ka has a shorter leg and a longer leg. The angle lever is at the free end of the shorter leg 2ka in a swivel bearing 2kas mounted pivotably with a vertical pivot axis. The swivel bearing 2kas is in the same way as the pivot bearing 2gs of the cylinder 2gz permanently mounted on the sash. Both camps 2kas and 2gs are mounted in a storage rack in rigid mutual assignment. The swivel bearing 2kas forms a stationary output bearing with the drive unit. The connection of the angle arm 2ka in the area of its angled vertex 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 bell crank 2ka is as a glider 2kag and is in the slide rail mounted on the frame side 2ks of the door puller 2 can be engaged and disengaged automatically. In the in the slide rail 2ks The angle lever forms the engaged position 2ka with the slide rail 2ks a power-transmitting rod as a special sliding arm rod 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 °, ie in the partial opening area between a door opening of 30 ° and the closed position of the door, the angle lever is 2ka as a force-transmitting sliding arm with its glider 2kag into the slide rail 2ks intervening led.

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

In the first dead center position, ie in the coupling / uncoupling position of the sliding arm 2ka , is the closing spring 2gf the piston-cylinder unit 2gkz more tensioned than in the second dead center position, ie in the end position which is assigned to the closed position of the door. Through the first dead center position of the sliding arm 2ka the tension of the closer spring, ie the charge that the closer spring assumes in the engaged / disengaged position, is maintained in the disengaged position.

As soon as the slide arm 2ga is in the slide rail 2ks is engaged, the first dead center position is automatically released during the closing process and the sliding arm 2ka by the action of the closing spring 2gf driven in the closing direction, relieving the tension of the closing spring 2gf . The sliding arm 2ga rotates in 3.2 clockwise and runs in the slide rail 2ks in 1 To the right. The sliding arm moves during the opening process 2ka exactly reversed. The closing spring is in a corresponding manner 2gf charged when the door is opened, as long as the slide arm 2ga is in the slide rail 2ks is engaged.

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

For engaging and disengaging the at the free end of the sliding arm 2ka trained glider 2kag points the slide rail 2ks an opening on the front 2kö on. This opening opens into a slideway within the slide rail via an inlet slope 2ks in which the glider 2kag is guided in the opening direction after coupling during the closing movement and the return movement. This slideway in the horizontally mounted slide rail 2ks can depending on the variant of the auxiliary drive 2 be linear or non-linear. The one and Disengaging 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 1 shown, all of 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 , through a common cover housing 3fh are covered and all components of the drive device mounted on the door frame side, ie the slide rail 1ks the door closer and the slide rail 2ks of the door puller, through a common cover housing 3rh are covered. This cover housing 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 housing 3fh , 3rh can each be formed in one piece, but it is also possible to form them from several subsections over the longitudinal extent. The common cover 3rh and 3fh is designed 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 mount the components to be mounted fixedly on the door leaf on a common mounting plate 3fm , which is preferably installed in a standard hole pattern on 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 1 ).

The assembly of the mounting plate to be mounted on the wing side 3fm in a standard hole pattern of the door leaf means that the fastening of the mounting plate 3fm takes place on the wing via a mounting hole pattern that is formed in the portion of the mounting plate near the strip. This mounting hole pattern is in 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 belt, in which the drive unit of the auxiliary drive 2 , ie the drive unit 2g , is mounted, is the mounting plate 3fm not screwed to the sash, as there is no standard hole pattern in this area of the sash.

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

The mode of operation of the drive device:

• Aus der in 1 dargestellten Schließlage der Tür lässt sich die Tür 3 öffnen, indem der Türflügel 3f manuell in Öffnungsrichtung geschwenkt wird. Hierbei dreht der Türschließergleitarm 1 ka mit der drehfest verbundenen Türschließerwelle 1w um die Drehachse der Türschließerwelle 1w im 1 im Gegenuhrzeigersinn. Der Gleitarm 1ka wird dabei mit seinem als Gleiter ausgebildeten freien Ende in der Gleitschiene 1ks derart geführt, dass das freie Ende des Gleitarms 1ka in der Darstellung in 1 nach links läuft.

How the sliding arm door closer works 1 and the auxiliary drive 2 composite door closer device 10 is as follows:

• From the in 1 The door can be closed in the illustrated closed position of the door 3 open by the door leaf 3f is swiveled manually in the opening direction. The door closer slide arm rotates 1 ka with the rotatably connected door closer shaft 1w around the axis of rotation of the door closer shaft 1w in the 1 counterclockwise. The sliding arm 1ka is in the slide rail with its free end designed as a slider 1ks guided in such a way that the free end of the sliding arm 1ka in the representation in 1 runs to the left.

During this opening movement, the toggle-like sliding arm also rotates 2ka of the auxiliary drive 2 , in a corresponding manner by the free end of the sliding arm 2ka with its free end in the slide rail 2ks runs to the left in the illustration in the figures. The toggle-like sliding arm linkage that results from the angle arm 2ka and the piston rod 2gks the piston-cylinder unit 2gkz composed, rotates here in a corresponding manner around the axis of the wing-mounted pivot bearing 2gs . However, it is essential in the illustrated embodiment that this toggle-like linkage, ie the free end of the angled sliding arm 2ka , automatically from the slide rail 2ks disengages as soon as the door opening angle predetermined for this is reached from the closed position. In the exemplary embodiment shown, this takes place at a door opening angle of approx. 30 °. The toggle-like linkage reaches this angular position 2k its first dead center position. When uncoupling from the slide rail 2ks the angle arm remains 2ka in the angular position of this dead center position. In this position, the angled arm is quasi locked against further rotation and moves out of the in this angular position when the door is opened further front opening 2kö the slide rail 2ks out. The angle arm remains in the dead center position 2ka quasi locked. The piston rod of the piston-cylinder device with the closing spring also remains locked in this position.

If the door is to be brought from the open position back into the closed position, the closing movement takes place with the angle arm disengaged 2ka up to the predetermined engagement angle position. The angle arm 2ka is therefore unchanged in the dead center position of the 3.1 and 3.4 that she took when disengaging the clutch. As soon as the door leaf has reached the predetermined door opening angle of approx. 30 ° during the closing process, the angle arm fixed in this engagement / disengagement angle position comes into play 2ka with its free end, ie the glider 2kag , again for coupling into the slide rail 2ks . The free end of the sliding arm 2ka with the glider 2kag moves into the opening of the slide rail 2ks one. When the door is closed further, the angle arm is 2ka with its free end in the slide rail 2ks is engaged and runs in the representation in 1 in the slideway of the slide rail 2ks to the right through the slide rail 2ks guided. 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. I. E. the closing process is then carried out by the auxiliary drive 2 supports. The toggle lever finally reaches its in when the door is in the closed position 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 swiveled back into the open position by manually pulling the door leaf open. During this opening movement, the angle arm is pivoted 2ka the dead center position is automatically canceled and the closer spring is recharged.

This in 4th The second embodiment shown differs from that in the 1 until 3 illustrated embodiment only in that in the embodiment in 4th 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 away from the belt in the common rail housing, by the slide rail in a section near the belt 1ks of the main drive is formed and adjacent to it on the side of the slide rail facing away from the belts 1ks the slide rail 2ks of the auxiliary drive is formed. The electric door opener which forms the tumbler component 4r mounted on the frame side is conventionally constructed with a movably mounted door opener latch which 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 exemplary embodiment shown, forms the tumbler component 4r mounted on the frame side.

The tumbler component 4f mounted on the sash side is designed as a counter-element which interacts with the tumbler component on the frame side. 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 exemplary embodiment in FIG 4th in that the wing-side tumbler component 4f on the common wing-mounted mounting plate 3fm is mounted. The door closer housing is located on this mounting plate in the section close to the belt 1g of the main drive 1 and next to it the drive unit 2g of the auxiliary drive 2 assembled. The mounting plate 3fm only has a screw fastening in the standardization hole pattern of the door leaf in the section near the hinge 3f on. 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 further away from the tape 3fm in which the housing 2g of the auxiliary drive 2 as well as the wing-side tumbler component 4f are mounted on the mounting plate, the mounting plate 3fm no screw connection with the door leaf 3f on. This results in advantages in connection with the installation 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 close to the hinge.

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

In the 5a - 5c and 6th The illustrated second exemplary embodiment is in each case 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 one on the sash F. mounted drive unit 1a and a power transmission device 1k as a slide rail linkage with a slide arm 1ka and a slide rail 1ks . The sliding arm 1ka is non-rotatably with one in a housing of the drive unit 1g mounted output shaft 1w coupled and the slide rail mounted fixed to the frame 1ks guided. In the exemplary embodiment shown, the main drive is intended as a sliding arm door closer with a drive unit 1g be designed with a closer spring and hydraulic damping device.

The auxiliary drive of the second embodiment:

The auxiliary drive 2 is in the illustrated case from a drive unit 2g and a power transmission linkage 2k educated. The drive unit 2g is integrated in a 2ss slide rail and fixed in a fixed position. The slide rail 2ss closes on the slide rail 1ks of the main drive 1 on. In the case shown, the two rails are 1ks and 2ss formed as sections of a common, continuous slide rail. That in the section 2ks Drive unit integrated in the slide rail 2g the auxiliary drive comprises a spring accumulator 2f or alternatively or additionally an electric motor. The downforce 2aa of the spring accumulator 2f or the electric motor works with the one in the slide rail 2ks guided glider 2kag together. It is a slider at the free end of the sliding arm 2ka . The sliding arm 2ka is with its bearing end in a pivot bearing mounted on the wing side 2kd pivoted and with its free end over the slider 2kag guided in the slide rail 2ss. The glider 2kag is with the free end of the output 2aa of the drive unit integrated in the slide rail 2ss 2g connected. The downforce 2aa is guided in the slide rail 2ss along the guide track of the rail so as to be linearly movable. The glider 2kag is taken along here. The slide rail 2ss forms one with the drive unit 2g stationary output bearing.

The downforce 2aa is guided in the guideway of the slide rail and 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 downforce 2aa but is also understood as a linear output if, in a modified version, 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 the case of those between the primary output of the drive unit and the output guided in the guide track of the slide rail 2aa a transmission is switched. The primary output can here, for. B. be designed as a rotary output. It can be designed as a rotating threaded spindle on which a threaded nut runs, which is linearly guided in the guide track, and the slide arm 2ka z. B. by taking the slider with you 2kag drives.

As from the 5b and 5c recognizable is the sliding arm 2ka of the auxiliary drive 2 with the drive unit 2g in the slide rail 2ks can be engaged and disengaged.

The coupling / uncoupling point is in the exemplary embodiment 5b , 5c between the free end of the slide arm 2ka and the output member guided in the slide rail 2ss 2aa of the drive unit mounted in the slide rail 2ss 2g , ie between the connecting end of the sliding arm 2ka and the output of the drive unit 2g educated.

The coupling and uncoupling takes place automatically during the opening and closing process at a certain door opening angle. the 5b shows the door position at the door opening angle at which the clutch is engaged during the closing process and disengaged during the opening process. If the door opening angle is smaller than this disengagement and engagement angle position, the sliding arm is 2ka engaged (see 5b and 5a ). If the door opening angle is greater than the engagement / disengagement angle position, the slide arm is disengaged (see 5c ).

The sliding arm remains in the disengaged position 2ka in this exemplary embodiment on the rod bearing, ie in the case shown in FIG 5c on the wing-side pivot bearing 2d, in a locked angular position of the wing F. protruding. The locking of the angular position can by a take place with the sliding arm interacting locking device. The locking device is in the pivot bearing 2kd educated. The locked angular position corresponds to the angular position that the sliding arm 2ka assumes when engaging / disengaging, ie the angular position in 5b . During the sliding arm 2ka is disengaged, the spring accumulator remains 2f of the drive unit 2g in the charged position in which the decoupling took place. It is the charged position that the spring accumulator reached during the opening process with the sliding arm coupled. For this determination of the spring accumulator is in the area of the drive unit 2g a locking device is provided. It is switched on when the sliding arm is disengaged 2ka and switched off by releasing the spring accumulator with the coupling of the sliding arm 2ka .

The coupling process between the free end of the sliding arm 2ka and the one in the slide rail 2ks guided glider 2kg takes place automatically when the door is closed at the predetermined door opening angle, which is shown in 5b is shown. The free end of the sliding arm protruding in this angular position 2ka drives with his glider 2kag in this door open position in the slide rail 2ks one, namely via a run-in bevel, not shown, through a front opening in the slide rail 2ks and couples with the output member which is in the waiting position and is designed as a slider 2aa on. With the coupling, the spring energy store arranged in the slide rail is charged during the previous opening process 2f forcibly enabled. Due to the discharge of the spring accumulator that takes place in this way 2f becomes the glider 2aa including the glider coupled to it 2kag and sliding arm 2ka driven in the closing direction. The coupled gliders 2kag and 2aa are moved to the right in the illustration in the figures and the slide arm 2ka 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 1a 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 swiveling the door leaf F. in opening direction.

When the door is opened, the sliding arm 2ka in the representation in the figures around the pivot bearing 1 kd rotated counterclockwise. The glider 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 door opening angle for coupling in and out, which is specified in 5b shown is reached, the disengagement of the sliding arm takes place automatically 2ka . The disengaged sliding arm 2ka then remains fixed in the predetermined angular position which it assumes when uncoupling, protruding from the wing-side pivot bearing 1kd.

Also the output glider 2aa remains after disengaging the sliding arm 2ka in its position, which it assumed when uncoupling, determined by the already mentioned locking device. Because of this automatically occurring determination, the one with the output slider also remains 2aa connected storage spring 2f as long as the sliding arm 2ka is disengaged in the charged state that the accumulator spring 2f by the previous opening process with the sliding arm engaged 2ka has reached.

The auxiliary drive 2 is thus during the opening process as long as the sliding arm 2ka is engaged, charged, ie when the door is opened in the first opening angle range. The auxiliary drive supports the closing process 2 by discharging the spring accumulator the closing process 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.

6th shows a modified embodiment which differs from the embodiment of FIG 5a - 5b differs in that the coupling / decoupling point of the sliding arm 2ka not between the output of the drive unit 2g and the connection end of the slide arm 2ka is formed, but in the area between the wing-mounted pivot bearing 1 kd and the sliding arm 2ka in the area of the bearing end of the sliding arm. The sliding arm also remains in this modified version 2ka as long as it is disengaged, in the angular position it was in when it was disengaged. Here, too, there is a locking device for the angular position of the disengaged sliding arm and a locking device for charging the storage spring 2f intended. This can be done by locking the sliding arm 2ka take place in the predetermined angular position in the manner of a dead center position, ie in a manner similar to the embodiment of FIG 1 until 4th . This means that the accumulator spring is also used in this exemplary embodiment 2f remains in the charged position that it was when the sliding arm was disengaged 2ka had.

What is essential for the 5 and 6th illustrated embodiments that the frame-mounted components of the main drive 1 and the auxiliary drive 2 , ie the slide rail 1ks of the main drive 1 and the slide rail 2ss with the storage spring stored therein 2f through a common, continuous cover on the frame side 3rh are covered.
