Description

The present invention relates to a device for at least partially automatic actuation of a door leaf. Furthermore, the invention relates to a system for at least partially automatic actuation of a door leaf.
Door operators for automatically operating a door are known in principle. For driving often electrical energy, especially electricity, used to supply drive elements of the door with electricity. The current is usually conducted via connecting means between the door leaf and door frame, said connecting means are normally passed along in the form of a cable outside between the door leaf and door frame. The disadvantage has been found that such fasteners often affect the design of the door and also exposed to the risk of damage.

It is therefore the object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a device for at least partially automatic actuation of a door leaf, which allows a cost-effective and simple installation and is protected from damage.

The above object is achieved by a device having the features of claim 1 and a system having the features of claim 12. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. there apply features and details which are described in connection with the device according to the invention, of course, also in connection with the system according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or can be.

A device according to the invention for at least partially automatic actuation of a door leaf has at least one drive for actuating a door leaf. Furthermore, the device is equipped with a Zargenelement for guiding the door leaf. The drive has at least one drive rotation axis. Wherein a lever kinematics with at least one lever element and at least one first bearing is rotatably mounted about this drive axis of rotation. The drive rotation axis is further arranged on the drive and driven by the drive. The drive may be a motor drive, a hydraulic drive, a pneumatic drive, a gear drive, in particular a gear, or a spring drive. Furthermore, the lever kinematics can be arranged on at least one second bearing in such a way that it can rotate in rotation about a frame pivot axis. The lever kinematics may have a cover or be arranged in a housing. A protection of the lever kinematics especially against environmental influences such as moisture, dust or UV radiation, but also by mechanical influences can be achieved. The Zargen rotation axis is arranged on a Zargenelement and guidable by the Zargenelement.Ferner thereby the door leaf in an open position and / or in a closed position überführbar.In the open position, the door is spaced from a door frame or a door frame arranged such that a Passage is released, wherein closed in the closed position of the door and no Passage through a door is possible. Furthermore, the lever kinematics has at least one connecting element for transmitting electrical energy and / or data between at least one energy source and an energy receiver on the door leaf. In particular, electrical energy can be understood as energy, it being possible for the energy source to be a power source. Furthermore, alternatively or additionally data can be transmitted, in particular via the state of the door leaf. Such data can be used, for example, for detecting the position of the door leaf or for displaying the state of the door leaf. In this case, the open position, the closed position or the performed movement of the door leaf can be displayed on a power receiver, such as a display device. Further, when operating a door leaf, for example, electrical energy can be used to convert it from an open position to a closed position. The door leaf can also be kept in a position, in particular the open position and / or the closed position. Furthermore, the force required to transfer the door leaf from the open position into the closed position can be reduced by the supply of electrical energy. The connection means may advantageously be an electrical cable. Advantageously, the connecting means is thus performed without interruption. A device according to the invention is characterized in that the connection means for rotational compensation on the drive rotation axis and / or the frame rotation axis has at least one twisting portion which is formed twisted.

The connecting means is designed twisted, so that a twisting of the connecting means is formed. As twisting the twisting of the connecting means can be understood. The twist is through acting Tordiermoment brought about, whereby torsions of a body axis can arise. In this case, in particular, a voltage can arise, which can be defined as the ratio of an acting torque to a resisting torque during a twisting (twisting) of a body. A twist is the twisting of a body, which results from the effect of a Tordiermoments. A Tordiermoment can act in particular on a connecting means when it is rotated perpendicular to its longitudinal axis. Due to the resulting torsion, a twisting angle, which results from the twisting moment divided by a Tordiertäägheitsmoment arise.

It is also advantageous if the twisting portion is about 10 mm to about 200 mm, preferably more than 20 mm. It is conceivable that the connecting means has a fixed clamping at least on one side of the Tordierabschnitts. In particular, it is conceivable that the Tordierabschnitt directly has at least one fixed clamping.

A twisting portion has first and second ends. The clamping can preferably take place at the two ends of the Tordierabschnitts. Thus, the Tordierabschnitt is on the one hand connected to the drive and on the other hand with the lever kinematics, which perform relative to each other during the opening movement of the door. If, during a movement of the door leaf, for example from the open position to the closed position or vice versa, a rotation of the lever element takes place about the drive rotation axis, this rotation is therefore transmitted to the twisting section. In the present case, the connecting means can carry out a rotational movement in the form of a stable rotation about a fixed axis, in particular the drive rotation axis and / or the frame rotation axis, by itself being twisted in the twisting section. At least one of the ends of the twisting section can perform a movement, in particular a rotational movement, during a rotation of the lever element about the drive rotation axis. Since the other end of the Tordierabschnitts can also be clamped, in particular fixed, this end of Tordierabschnitts is rotated to the other end. A Tordiermoment can thus be transferred to the Tordierabschnitt. Also a twisting is possible with a rotation of the lever element about the Zargen rotation axis, which can also transmit this rotation on the Tordierabschnitt.

While in the known solutions, the connecting means went outside the device, the connecting means in the range of Hebelkinemtik is now much better protected against damage. This is already the case in that the connecting means is less easily recognizable than is the case with known solutions. Also recesses or images in the range of lever kinematics for the connecting means are conceivable, which further increase this protection.

Another advantage is the small footprint of Tordierabschnitts. Thus, even with a low height of Tordierabschnitt provide the desired rotation compensation. This is particularly the case when the Tordierabschnitt is at least partially deflected, as will be explained later. Accordingly, the device according to the invention does not require any additional installation space, since the twisted connection means can be guided in the lever kinematics or in the drive and / or frame element. In a twisting the connecting means is advantageously twisted up to a certain twisting angle, so that the structure of the connecting means is not damaged.

The lever kinematics according to the invention can advantageously have at least one lever element in a first exemplary embodiment. Furthermore, it is conceivable that the lever kinematics in a further embodiment has two lever elements. In the first embodiment with a lever kinematics with a lever element this is arranged rotatably on a frame pivot axis in a Zargenelement. The frame pivot axis is advantageously arranged in the form of a sliding axis of rotation in a Zargenelement in the form of a sliding element and can be guided by the slider. In this case, the sliding element, in particular a sliding block, used as a transmission element. Furthermore, the door leaf can thereby be converted into an open position and / or into a closed position. A sliding element can advantageously slide on a particular horizontal guide, in particular a slide, almost frictionless. During a transfer of the door leaf from the open position to the closed position, the sliding element slides along in the slide rail. In a transfer of the door from the open position to the closed position or vice versa, the slider can change its position in the slide rail. At the same time, the lever element performs at least the second bearing a rotational movement about the sliding axis of rotation in the sliding member. It is conceivable that the sliding element designed spring-loaded and can be guided by a spring. Furthermore, the lever element is rotatably connected to the drive about the drive axis of rotation.

In the exemplary embodiment with two lever elements, these are likewise arranged on a frame pivot axis in a frame element. In this case, the door leaf can be converted by the Zargenelement in an open position and / or in a closed position. A Zargenelement can advantageously be arranged stationary Tärztargen side. The frame pivot axis is advantageously arranged in the form of a stationary connection axis of rotation in a Zargenelement in the form of a connecting element. During a transfer of the door leaf from the open position to the closed position, a lever element of the lever kinematics rotates about the Zargen rotation axis in which the lever element is rotatably mounted around the second bearing. The second lever element of the lever kinematics is further rotatably connected to the first lever element of the lever kinematics and rotates in the transfer of the door leaf from the open position to the closed position to a third camp. In a transfer of the door leaf from the open position to the closed position or vice versa, the two lever elements are rotated about the third bearing to each other, so that these two lever elements in the open position of the door form a larger angle to each other than in the closed position of the door leaf. Furthermore, the second lever element is rotatably connected to the drive about the drive axis of rotation.

In a device according to the invention, the twisting section may preferably have at least one first twisting section and one second twisting section. It is particularly advantageous if the first Tordierteilabschnitt has a greater length than the second Tordierteilabschnitt. The Tordierabschnitt preferably runs in the lever kinematics. In addition, the lever kinematics in particular comprises a lever element in which the connecting means can be guided with the Tordierabschnitt. The connecting means is preferably guided by the frame pivot axis through the lever kinematics, in particular the lever element, to the drive axis of rotation. At least one Tordierabschnitt can advantageously be located at the transition from lever kinematics to drive and / or Zargenelement. The first Tordierteilabschnitt can preferably in the lever kinematics, be guided in particular in the lever element and the second Tordierteilabschnitt in the transition between lever kinematics and drive or Zargenelement. The first and the second Tordierteilabschnitt together form an entire Tordierlänge. The twist length is advantageously about 10 mm to about 200 mm, preferably more than 20 mm. The twist length is defined as the area of the lanyard over which the twist can propagate. The longer the Tordierlänge, the less mechanical impairment takes place on the connecting means at the same Tordierwinkel. Preferably, the two Tordierteilabschnitte a different orientation. In other words, so the twist can be redirected to another orientation. This makes it possible to divide a large Tordierlänge to different orientations, so that in particular a small overall height of the device with a large Tordierlänge can be combined.

Moreover, it may be provided in the device according to the invention that the first Tordierteilabschnitt transverse to the drive axis of rotation and / or to the Zargen rotation axis and the second Tordierteilabschnitt along the drive axis of rotation and / or Zargen-axis of rotation. In this case, the first Tordierteilabschnitt transverse to the drive axis of rotation and thus at least partially parallel to the course of the lever kinematics or the lever element. The second Tordierteilabschnitt may further along the drive axis of rotation and / or Zargen-axis of rotation and thus in the direction of the axis, by which the drive or the Zargenelement moves, run. It can further be provided that the first Tordierteilabschnitt is arranged in particular with one end at the transition between the drive axis of rotation and / or Zargen-axis of rotation and lever kinematics. In the further course, the first Tordierteilabschnitt in the second Go over the twisting section, which continues in the lever kinematics and ends there. Advantageously, can be achieved by a plurality of Tordierteilabschnitte that the lever kinematics together with the drive and / or the Zargenelement only comprises a flat height, since the Tordierteilabschnitte are installed in the lever kinematics and no further space must be claimed by the twisting of the connecting means. This is therefore the already mentioned reversal of the goal length.

It can also be provided in a device according to the invention that the Tordierteilabschnitte to each other have a deflection angle. In particular, the deflection angle corresponds to about 50 ° to about 110 °, preferably about 80 ° to about 100 °, and more preferably about 90 °. The first Tordierteilabschnitt can thus extend from the transition of the lever kinematics to the drive axis of rotation and / or Zargen-axis of rotation in the direction of the lever kinematics, in particular along the orientation of the axis. The first Tordierteilabschnitt can also go into the second Tordierteilabschnitt, which runs along the lever kinematics, ie transverse to the drive axis of rotation and / or Zargen-axis of rotation. This transition designates the deflection angle in which the Tordierteilabschnitte to each other. By such a deflection angle of a Tordierteilabschnittes a particular extending by about 90 ° turn of the connecting means can be completed. Advantageously, the connecting means is not loaded by such a turn by about 90 °. Furthermore, the course of the connecting means does not form a right angle in the sense of two mutually perpendicular lines, but rather can take a rounded course. The connecting means is thus Protected and a longer life of the lanyard can be guaranteed.

It can also be provided in a device according to the invention that the twisting portion is guided at least in sections in at least one recess in the lever kinematics. Through a recess in the lever kinematics a Tordierteilabschnitt can be protected in particular against adverse effects, eg by environmental influences such as dust, moisture, UV radiation, but also by mechanical influences such as excessive, in particular plastic bending, stretching or upsetting. A recess may be, for example, a groove, a depression or a guide, which may be arranged in the lever element. Preferably, the recess is arranged within the lever element. In this case, the first Tordierteilabschnitt be guided in particular in a first part of the recess and the second Tordierteilabschnitt in a second part of the recess. Since the first to the second Tordierteilabschnitt preferably extends around a deflection angle and this deflection angle is continuously variable, it may be advantageous to provide two different recesses for the two Tordierteilabschnitte in order to keep the deflection flexible design and not to specify by a single recess the course. Alternatively, it is of course conceivable to choose a single recess for both Tordierteilabschnitte, in which the deflection still remains variably modifiable, for example, by creating a cavity or a movement space in the recess. Advantageously, can be increased by the leadership of the connecting means, in particular the Tordierabschnitts in a recess Tordierlänge. The recess preferably has a free cross-section which is larger than the circumference of the lanyard so as not to impose a geometric obstacle in the path of the twisting.

Furthermore, it is conceivable within the scope of the present invention for the device to have a twisting section which is designed to be twisted along a longitudinal axis of the drive and / or of the frame element. The twisting takes place along the longitudinal axis of the drive and / or the Zargenelementes, so that the Tordierung, in particular the rotation of the connecting means, is formed around a longitudinal axis. The longitudinal axis can advantageously be the drive rotation axis and / or the frame rotation axis. Furthermore, it is conceivable that the longitudinal axis is also a longitudinal axis parallel to the longitudinal axis of the output and / or Zargenelementes. During a rotation of the lever element about the drive rotation axis and / or the frame rotation axis, this rotation can be transmitted to the twisting section. This rotation is carried out in particular in a transfer of the door leaf in the open position or the closed position. By clamping the first end of the twisting section, in particular in the lever kinematics and clamping the second end of the twisting section in the drive and / or the frame element, a twisting of the twisting section thus takes place about the existing longitudinal axis of the drive and / or frame element. Thus, a particularly space-saving design can be achieved because the Tordierabschnitt can be particularly easily integrated into the device according to the invention.

It may also be particularly preferred in a device according to the invention that the connecting means is formed at least in sections as a flat cable. Alternatively or additionally, the connecting means can also be partially used as a ribbon cable, in particular as a flexible printed circuit board, be configured. Alternatively or additionally, the connecting means may also be at least partially configured as a round cable. A flat cable or a ribbon cable is a multi-core cable, in which the individual wires are parallel to each other. Multi-core ribbon cables have the advantage that they connect several wires at once, rather than soldering them separately. Flat cable or ribbon cable can have a variety of different wires. It is also conceivable that the flat or ribbon cables are designed with a shield, which may consist in particular of aluminum or copper foil. In particular, it is conceivable that the connecting means is designed as a flexible printed circuit board. These may be in particular printed circuits, which may be constructed in particular on flexible plastic carriers. In particular, copper is used as a conductor material. In addition, round cables are also conceivable as connecting means, which have a circular cross-section and in which the individual wires are arranged around the center. Round cables can have the same function as flat or ribbon cables. Advantageously, ribbon cables can be twisted simply because the individual wires are little bent when twisting a flat cable.

The list above is a non-exhaustive list. Electric motors are electromechanical converters with a high degree of efficiency and, in addition, small dimensions, which are therefore simple and space-saving to install. Furthermore, a hydraulic actuator is conceivable, which performs an energy transfer using a liquid. Advantageously, hydraulic actuators also require only a small space, so that a flexible adaptation to room specifications is given. Likewise, hydraulic actuators can be infinitely variable in their speed, have a high positioning accuracy and are quiet. In addition, pneumatic actuators are also conceivable that perform mechanical work by the use of compressed air. Pneumatic actuators are also infinitely adjustable, insensitive to temperature fluctuations and allow high working speeds. Furthermore, pneumatic actuators are also quiet. In addition, a cylinder is also conceivable that can be configured as a hollow cylinder. It can also be a tubular chamber around which a piston can be operated, which can thus act as a lifting column or telescopic drive. In addition, also pneumatic and hydraulic cylinders are conceivable, which are infinitely adjustable and operate quietly. Also conceivable are electrochemical actuators that combine a chemical reaction with electrical energy. In this case, a particularly low-noise use is also guaranteed. Further, a piezoelectric element is conceivable, wherein piezoelectric elements can perform a mechanical movement by applying an electrical voltage. Piezo elements may be designed in particular with certain crystals or piezoelectric ceramics. Advantageously, in a piezoelectric element by a relatively high voltage in high frequency, a small amplitude of movement can be carried out. Furthermore, a magnetic element is conceivable which applies a magnetic field, by which a body can be moved in this field. A magnetic element operates in particular low energy and low noise and is therefore particularly cost effective and user-friendly. In addition, a shape memory alloy can also be used, which is a metal that can be put into different structures. By applying a pulse, in particular an energy, the shape memory element is restored to its original form. In this case, a shape memory element can be used for a particularly long time with a low energy consumption. In addition, a shape memory element works very quiet. Also optical, acoustic or other display elements are conceivable that indicate the current state of the door leaf. This can be done in particular via optical elements, in particular an LED or OELD, which visualizes a state, in particular in a specific color code, such as green or red for the opening or closing state. Furthermore, lighting by means of a lighting unit of the door is conceivable that can illuminate the door and the passage space. Furthermore, acoustic signals, for example during the opening or closing operation of the door, conceivable that can indicate in particular a change of state. In addition, display elements, such as in the form of a display, such as a lettering or symbols, in particular different door states can also be displayed. Furthermore, control units are conceivable, which can transfer the door in various positions, in particular the open position or the closed position. Furthermore, it is possible that the door leaf can be held by a control unit in a position, in particular in the open position and / or the closed position. Furthermore, a control unit can also generate a force which reduces the force required to transfer the door leaf from the open position to the closed position. Furthermore, transmitting and / or receiving unit and sensor units are also conceivable which can generate data, in particular on the current state of the door leaf. Such data may, for example, be data for detecting the position of the door leaf, in particular whether it is in the open position or closed position. Furthermore, sensor units are conceivable which can detect the position of the door leaf, in particular the degree of opening of the door leaf. Such data may also be transmitted to an additional interface that may be in communication with a data network. Furthermore, such a data network can establish a connection to, for example, a control center remote from the door, for example a central control center, in which a remote diagnosis, in particular about the state of the door leaf and also a monitoring of the positions of the door can take place. Furthermore, it is conceivable that the door leaf is connected to a monitoring system, in particular a building monitoring system, by means of such an interface. This not only monitors the functions and positions of the door leaf In addition, the other energy receivers such as acoustic and optical elements or display elements can also be controlled. Advantageously, by using a plurality of energy receiver these can be used as a personal guidance system and in particular in an emergency or dangerous situation identify escape routes and release. The transmission of the data can be done via a connecting means, in particular a cable or also wirelessly, wherein the data can be transmitted for example by radio. Furthermore, the sensor unit may be a monitoring unit. In this case, an authorized passage through the door or the distance of a user to the door can be monitored. In addition, a camera unit is also conceivable which monitors or records the passage through the door. In particular, a coupling of a camera unit with a sensor unit is conceivable, so that a recording function of the camera unit is activated by the sensor unit. Furthermore, sensor units for monitoring security functions are conceivable, such as a closing edge protection. Furthermore, a locking system is conceivable which can convert the door leaf into a locking state and an unlocking state. In a locked state, the door leaf is in the closed position and can not be transferred to the open position.

Furthermore, it is conceivable within the scope of the present invention that the twisting section is predosed. The predorting can be done by a twisting angle. In this case, the Tordierabschnitt has a first end and a first end opposite the second end, which in the closed position of the door wing to each other have a twisting angle of not equal to 0 °, preferably between + - 10 ° and + - 110 °. The angle in which the two ends of the Tordierabschnittes each other stand forms the Tordierwinkel, wherein the apex of the Tordierwinkels is geradlinger extent in the longitudinal axis of the Tordierabschnitts. The predilection is twisted against an opening ordination, so that this predorting is reduced when the door leaf moves from the closed position in the direction of the open position. Advantageously, when the door leaf is transferred from the closed position to the open position, the twisting angle can be reduced. In a predilection of about 180 °, the ends of the twisting portion are twisted by about 180 ° to each other. The twisting advantageously runs uniformly over the entire twisting section, so that the connecting means is designed to be twisted uniformly. The connection medium can already be installed pre-ordered. By a predilection only a slight load of the bonding agent can be maintained. The predorting makes it possible, in particular, to make the twisting angle smaller than the total necessary opening angle at the corresponding longitudinal axis for the entire movement between the open position and the closed position.

Furthermore, it is conceivable in the context of the invention that the twisting angle is formed in the open position not equal to 0 °, preferably complementary or substantially complementary to the twisting angle in the closed position. This is understood to mean that the unthreaded state of the twisting section is between the open position and the closed position. In other words, the twisting angle in the open position has a different mathematical sign than in the closed position. Preferably, the amount of Tordierwinkels in the closed position corresponds to the amount of Tordierwinkels in the open position. In other words, the twisting in the two end positions, ie the open position and the closed position, is symmetrical. The neutral state without twisting the Tordierabschnitts is thus centered between the open position and the closed position. If, for example, a relative rotation of 180 ° must be compensated, the twisting angle can be predestined in the closed position 90 °, so that when the door is half open the neutral state is passed through with 0 ° twisting angle. As soon as the door leaf has reached the open position, the twisting angle is then -90 °. The amount of twisting and thus the degree of loading of the connecting means can thus be halved compared to the amount of rotation compensation. Thus, the durability of the connecting means can be further extended and / or the Tordierlänge be further shortened.

Furthermore, it is provided in the context of the present invention that the lever kinematics has a cranked course at least in sections. In particular, it is provided that the cranked course extends in the region of a connection section between the lever kinematics and the drive and / or in the region of the connection section between the lever kinematics and the frame element. By cranked lever kinematics, a better installation of the lever kinematics can be achieved. Furthermore, the cranked section of the lever kinematics may be an additional lever element, which is arranged in addition to the further lever element of the lever kinematics. By a cranked portion of the lever kinematics a clearance above the cranked part is created, which serves to simplify the assembly.

Likewise provided by the present invention is a system for at least partially automatic actuation of a door leaf. The system comprises a device according to the present invention and a guided Zargenelement in the Zargen-axis of rotation Lever kinematics is rotatably mounted. Accordingly, a system according to the invention brings the same advantages as have been explained in detail with respect to the device according to the invention.

Fig. 2b shows the door leaf 2 with the device 1 in an open position I according to a second embodiment. The sliding element 4 performs in such a change of the closed position II to the open position I, a sliding movement on the horizontal slide rail 4.2, so that the lever element moves 5.1.

Fig. 3a shows a schematic cross section through the lever kinematics 5, in particular a lever element 5.1. In the present case, the connection between the lever element 5.1 and Zargenelement 4 is shown. Alternatively, such a connection is also formed between lever element 5.1 and drive 3. By the lever element 5.1 in the Zargenelement 4 extends a connecting means 7 for transmitting electrical energy between at least one power source 8.1 and a power receiver 8.2. In the region of the transition between lever element 5.1 and frame element 4, the connecting element 7 has a twisting section 9, in which the connecting element 7 is guided by the lever element 5.1 into the frame element 4. Fig. 3b also shows an enlarged detail of the transition between lever element 5.1 and Zargenelement 4, in particular the Tordierabschnitts 9. The Tordierabschnitt 9 is divided into two Tordierteilabschnitte 9.1 and 9.2, wherein the first Tordierteilabschnitt 9.1 transverse to the drive axis of rotation and / or Zargen-axis of rotation 3.1, 4.1 runs and the second Tordierteilabschnitt 9.2 along a longitudinal axis of the drive 3 and / or Zargenelementes 4 runs. Between the two Tordierteilabschnitten 9.1, 9.2 a deflection angle α is shown. In particular, the deflection angle α is about 50 ° to about 110 °, preferably 80 ° to about 100 °, and more preferably about 90 °. In this way, a large part of the Tordierlänge is deflected in the horizontal, so that a flat design is possible.

Fig. 4 shows a cross section through the lever kinematics 5, in particular a lever element 5.1. In the present case, the connection between the lever element 5.1 and Zargenelement 4 is shown. Alternatively, such a connection is also formed between lever element 5.1 and drive 3. Furthermore, a recess 10 for guiding the connecting means 7 in particular of the Tordierabschnittes 9 is shown.

In this case, the recess 10 can be configured as a single recess (not shown) or as at least two different partial recesses 10.1, 10.2, wherein the first partial recess 10.1 receives the first Tordierteilabschnitt 9.1 and the second partial recess 10.2 the second Tordierteilabschnitt 9.2.

Fig. 5a and 5b show the Tordierabschnitt 9 of the connecting means 7 by a Tordierwinkel ß. The Tordierabschnitt 9 is formed around a longitudinal axis 11 of the drive 3 and / or Zargenelementes 4 twisted. The longitudinal axis 11 may correspond to the drive rotation axis 3.1 and / or the frame rotation axis 4.1 or be formed parallel thereto. The Tordierabschnitt 9 is preferably vorortiert, so that a first end of the 9.3 Tordierabschnittes 9 and this opposite second end of the Tordierabschnittes 9 9 are formed twisted to each other. In Fig. 5a is the first end of the 9.3 Tordierabschnitts 9 by + 90 ° with respect to a neutral position 0 in which no twisting of the connecting means 7 takes place twisted formed. In Fig. 5b is the second end of the 9.4 Tordierabschnitts 9 by -90 ° with respect to a neutral position 0 in which no twisting of the connecting means 7 takes place twisted formed. The ends of the Tordierabschnittes 9 can thus be formed twisted in different Tordierrichtungen. Advantageously, a twist takes place symmetrically, so that the amount of Tordierwinkels ß for the closed position II and the open position I is equal.

Fig. 6 shows a cranked course of the lever kinematics 5, wherein this cranked course takes place in particular in the region of a connection section 12 between the lever kinematics 5 and the drive 3 and / or the frame element 4. By a cranked course of the lever kinematics 5, a better installation of the lever kinematics 5 can be achieved in particular to a door 2. An improved one Space savings can be guaranteed. Furthermore, the cranked section of the lever kinematics 5 may be an additional lever element, which is arranged in addition to the lever element 5.1 in the lever kinematics 5. By a cranked portion of the lever kinematics 5, a clearance above the cranked part is created, which serves to simplify the assembly and can be used to save space.

Fig. 7 shows an inventive system 100 for at least partially automatic actuation of a door leaf 2. The door 2 is presently shown together with an entire door assembly, which consists of at least one door 2 and a door frame 13. Furthermore, a device 1 according to the invention is arranged at the upper end of the door leaf 2. The one part of the device 1, in particular the frame element 4 may preferably be arranged on the door frame 13.
