DETAILED DESCRIPTION OF THE DRAWINGS

(13) Throughout the different Figures, same parts of the device 100 and of the system 110 are always identified by the same reference numerals, and therefore, normally they will be only described once.

(14) The FIGS. 1a and 2a show a door leaf 101 in a closing position I. The FIGS. 1b and 2b show the door leaf 101 in an opening position II. The door leaf 101 is equipped with an inventive device 100 for at least partially automatically actuating the door leaf 101.

(15) The FIGS. 1a and 1b relate to a first exemplary embodiment of the device 100, and the FIGS. 2a and 2b relate to a second exemplary embodiment of the device 100.

(16) In this case, the inventive device 100 includes a drive 10, which has a drive axis of rotation 11. Furthermore, the device 100 includes lever kinematics 30 with one lever arm 31 (refer to FIGS. 2a and 2b) or two lever arms 31, 35 (refer to FIGS. 1a and 1b).

(17) From the side of the drive 10, the lever kinematics 30 is supported with a connection section 1 to be rotationally movable around the drive axis of rotation 11 of the drive 10. From the side of a door casing 102, the lever kinematics 30 is supported with a guiding section 2 to be rotationally movable around a casing axis of rotation 21. The casing axis of rotation 21 is disposed at a door casing-sided guiding device 200, which is able to guide the casing axis of rotation 21 linearly and rotatably in a guiding rail 201 (refer to FIGS. 2a and 2b), or only rotatably at a rotational bearing 202 (refer to FIGS. 1a and 1b). Furthermore, the lever kinematics 30 includes at least one transmission means 33 for transferring electrical energy and/or data between at least one casing-sided energy source 22 and a drive-sided energy recipient 12.

(18) The drive 10 and the lever kinematics 30 allow for transferring the door leaf 101 from the closing position I (refer to FIGS. 1a and 2a) into the opening position II (refer to FIGS. 1b and 2b).

(19) In the exemplary embodiment of the FIGS. 1a and 1b, the casing element 20 is shown as a stationary connecting element to the door casing 102, wherein said connecting element is supported at the rotational bearing 202 to be rotationally movable around the casing axis of rotation 21 as a stationary connection axis of rotation. Furthermore, the first lever arm 31 and the second lever arm 35 are supported to be rotationally movable with regard to each other around a joint 36. During a transfer of the door leaf 101 from the opening position II into the closing position I or vice versa, the two lever arms 31, 35 are rotated with regard to each other around the joint 36, so that said both lever arms 31, 35 in the opening position II of the door leaf 101 form a larger angle with each other than in the closing position I of the door leaf 101.

(20) In the exemplary embodiment of the FIGS. 2a and 2b, the casing element 20 is shown as a sliding element, wherein the latter is supported to be rotationally movable around a casing axis of rotation 21 as a sliding axis of rotation. In this case, the casing element 20, in particular the sliding element, is employed as the transmission element to the guiding rail 201 at the door casing 102. Advantageously, the guiding rail 201 may be configured as a horizontal guide, and assist the movement of the door leaf 101. In this case, the lever kinematics 30 includes only one lever arm 31.

(21) The FIGS. 3a and 3b, as well as the FIGS. 4a and 4b show the device 100 according to different further exemplary embodiments. However, the exemplary embodiments have in common that the connection section 1 has a cranked course, wherein a multi-layered functional compartment F for mechanically connecting the lever arm 31 and for electrically connecting the transmission means 33 to the drive 10 is configured along the cranked course of the connection section 1.

(22) The transmission means 33 is employed for transferring electrical energy and/or data between the casing-sided energy source 22 and the drive-sided energy recipient 12 at the door leaf 101. The data to be transferred may serve for example for detecting the position of the door leaf 101 or for displaying the condition of the door leaf 101. The energy recipient 12 may be embodied for visualizing the data with a display device. The electrical energy to be transferred may be employed for transferring the door leaf 101 from the opening position II into the closing position I. In this case, the closing force required for closing the door leaf 101 may be reduced, increased or adjusted according to a predetermined pattern course by the drive 10. Moreover, the door leaf 101 may be retained in at least one position, for example the opening position II.

(23) At least section-wise the transmission means 33 may be configured as a flat cable, flat ribbon cable, a flexible printed circuit board or as a round cable. Furthermore, the lever arm 31 may include a guiding groove 32 for the transmission means 33, which groove in the FIGS. 3a to 4b is diagrammatically illustrated by dashed lines. Thus, the transmission means 33 may be laid through the lever arm 31 in a countersunk and protected manner. Moreover, the lever arm 31 may include a groove covering 34 for the guiding groove 32, and thus for the transmission means 33. In this case, the groove covering 34 assists in protecting the transmission means 33 against manipulation and/or environmental influences.

(24) According to the disclosure, a multi-layered functional compartment F having multiple layers F1, F2, F3 is formed by the cranked course of the connection section 1, which are identified in the FIGS. 4a and 4b. Thereby, the functional compartment F may be employed for a plurality of different application possibilities.

(25) On the one hand, with the connection section 1, at least one mounting layer F3 is formed in the functional compartment F, in which the connection section 1 may be mounted with a lower terminal part to be rotationally movable around the drive axis of rotation 11 by means of an attachment means 4, for example in the shape of a screw. In this case, the attachment means 4 may be connected torque-proof to a rotatable bolt 5, in order to allow for a rotation of the lever 31 around the drive axis of rotation 11.

(26) On the other hand, in a further reception layer F2, the functional compartment F is employed as an additional compartment, in order to be able to readily place the attachment means 4 when mounting of the device 100 within the functional compartment F.

(27) Furthermore, in a guiding layer F1, the functional compartment F is used as a cable compartment for the passage of the transmission means 33. Moreover, the functional compartment F is configured such that a plug-in unit 50 may be disposed in the guiding layer F1, in order to electrically connect the transmission means 33 to the drive 10 by simply plugging it in into the plug-in unit 50. In the following different configurations of the plug-in unit 50 will be explained in detail. Moreover, the functional compartment F, in particular the guiding layer F1 may be embodied with a traction relief unit 40 for the transmission means 33. Likewise in the following, different configurations of the traction relief unit 40 will be explained in detail.

(28) Advantageously, the functional compartment F, at least in the guiding layer F1, may be employed for twisting and/or for deflecting the transmission means 33, in order to provide for an improved length and/or rotation compensation for the transmission means 33 within the functional compartment F.

(29) As shown in the FIGS. 3a and 3b, as well as in the FIGS. 4a and 4b, the functional compartment F, in particular in the guiding layer F1, includes an entry area E1 into the functional compartment F, and an exit area E2 from the functional compartment F for the transmission means 33, which are embodied such that the transmission means 33 is guided transversely to, respectively through the drive axis of rotation 11 through the functional compartment F. The traction relief unit 40 may be disposed at the entry area E1, and the plug-in unit 50 may be disposed at the exit area E2. A vertex is formed at the transmission means 33 by means of the passage of the transmission means 33 through the drive axis of rotation 11. Thereby, the advantage may be achieved that a length compensation of the transmission means 33 may be obtained during a relative rotation between the lever kinematics 30 and the drive 10. As the transmission means 33 extends through the drive axis of rotation 11, the length thereof, which is accommodated in the functional compartment F, corresponds to a diameter of the functional compartment F, and will not be modified during the relative rotation of the lever kinematics 30 and the drive 10.

(30) As shown in the FIGS. 3a and 3b, the connection section 1 includes a cover element 3, in order to at least partially delimit, mechanically protect or seal the functional compartment F. For this purpose, a closing element 6 and/or a seal 6 or a combined closing and sealing element may be employed. Thereby, the inside of the device 100 with sensitive electrical connections, potentially sensor technology and mechanical attachment means 4 may be closed off and/or sealed.

(31) In the different exemplary embodiments in FIG. 3a (without torsion), and in the FIGS. 3b as well as 4a and 4b (with torsion), the traction relief unit 40 is diagrammatically illustrated. Basically, the traction relief unit 40 is embodied with a first connecting element 41 and a second connecting element 42, in order to positively and/or non-positively immobilize the transmission means 33 between the first connecting element 41 and the second connecting element 42. In this case, it should be noted that a non-positive connection is not established by pressing onto the transmission means 33, but by means of a light, preferably repeated bending of the transmission means 33, whereby a kink-free friction connection is realized. The traction relief unit 40 serves for inhibiting the transmission of a mechanical traction at the electrical connection locations to the drive 10, and for preventing a release of the transmission means 33 from the drive 10. In particular in one exemplary embodiment of the guiding device 200 according to the FIGS. 2a and 2b in the shape of a guiding rail 201, the transmission means 33 may be guided under tension at the casing element 20. However, also in a pure rotational bearing 202 of the casing element 20 according to the FIGS. 1a and 1b, a tension may be present in the transmission means 33. Said tension may be eliminated from the transmission means 33 at the drive side by means of the traction relief unit 40.

(32) For this purpose, the traction relief unit 40 may include a labyrinth guide 43 between the first connecting element 41 and the second connecting element 42, as shown in the FIGS. 3a to 4b in an enlarged view of the traction relief unit 40. By means of the labyrinth guide 43, the tensile stress from the transmission means 33 may be deviated to the traction relief unit 40. The labyrinth guide 43 may deflect the traction force several times, and enhance the distribution of the traction force at the traction relief unit 40. However, the labyrinth guide 43 allows for retaining the transmission means 33 in a kink-free manner in that a certain friction connection is established.

(33) As shown in the FIGS. 3b, 4a, and 4b, the labyrinth guide 43 may be configured such that the transmission means 33 is passed in a twisted manner around a first angle of torsion β1 through the labyrinth guide 43. Thereby, the transmission means 33 may be rotated around the longitudinal axis L thereof around the first angle of torsion β1, as shown in the enlarged view of the traction relief unit in the FIGS. 3b to 4b, and in the diagrammatical view of the transmission means 33 in FIG. 5a. Such a twisted immobilization of the transmission means 33 at the traction relief unit 40 assists in achieving a rotation compensation at the transmission means 33, if the lever kinematics 30 and the drive axis of rotation 11 rotate in relation to each other. A rotation compensation by means of a torsion is in particular advantageous with a flat ribbon cable as a transmission means 33.

(34) As shown in FIG. 4a, the transmission means 33 may include only one torsion around a first angle of torsion β1, preferably of 90°, at an entry area E1 into the functional compartment F, which for example may be realized by means of the traction relief unit 40.

(35) As shown in the FIGS. 3b and 4b, the transmission means 33 may include a first torsion around a first angle of torsion β1, preferably of 90°, at the entry area E1 into the functional compartment F, and a second torsion around a second angle of torsion β2, preferably of 90°, at the exit area E2 from the functional compartment F. Advantageously, tensions may be intercepted and equalized by the first torsion, which tensions develop in the axis of rotation x, z of the lever arm 31, as indicated in the enlarged view of the traction relief unit 40 in the FIGS. 3b and 4b or the FIG. 5a. Moreover, the second torsion is able to intercept and equalize tensions, which develop in the plane x, y, which is determined by the longitudinal axis L of the lever arm and the drive axis of rotation 11, as indicated in the FIG. 5b. Thereby, in a simple and advantageous manner, a reliable three-dimensional rotation compensation may be established at the transmission means 33 having even the shape of a flat ribbon cable.

(36) Furthermore, as shown in the FIGS. 3b and 4b, the transmission means 33 may include at least one deflection having a deflection angle α, preferably of 45°, at an exit area E2 from the functional compartment F, in order to deflect the transmission means 33 from an orientation transversely to the drive axis of rotation 11 of the drive 10 into an orientation parallel to the drive axis of rotation 11. The deflection of the transmission means 33 may be understood as a kinking of the transmission means 33 under a change of direction of 90°. By deflecting the transmission means 33 into the direction parallel to the drive axis of rotation 11, the transmission means 33 may be guided underneath the connection section 1 directly to the drive 10.

(37) Furthermore, as shown in the FIGS. 3a and 3b, as well as 4a and 4b, the connection section 1 at the exit area E2 from the functional compartment F may include a plug-in unit 50 for the transmission means 33, in order to electrically connect the transmission means 33 to the drive 10. Thus, a simple contacting of the transmission means 33 to the drive 10 may be realized.

(38) As shown in the FIGS. 3b and 4b, the plug-in unit 50 may be embodied such that the transmission means 33 is guided through the plug-in unit 50 deflected around a deflection angle α, preferably of 45°, and/or twisted around a second angle of torsion β2. Thereby, at the exit area E2 from the functional compartment F, the transmission means 33 may be accommodated by the plug-in unit 50, preferably with a rotation compensation and/or traction relief.

(39) In the exemplary embodiment of the FIGS. 3b and 4b, the plug-in unit 50 may include a plug-in guide 51, which is configured at least partially cylinder-envelope shaped with regard to the drive axis of rotation 11 of the drive 10, in order to deflect the transmission means 33 from an orientation transversely to the drive axis of rotation 11 into an orientation parallel to the drive axis of rotation 11, wherein in addition the plug-in guide 51 includes a slot 52, which is oriented parallel to the drive axis of rotation 11 of the drive 10, in order to introduce the transmission means 33 into the plug-in guide 51 in a twisted manner.

(40) On the left side in FIG. 4b, the plug-in unit 50 is illustrated enlarged, in order to illustrate the plug-in guide 51, configured cylinder-envelope shaped, and the slot 52 at the entry into the plug-in guide 51, which slot extends parallel to the drive axis of rotation 11. Thus, a flat ribbon cable as the transmission means 33 may be accommodated kink-free and break-free in the plug-in unit 50, wherein the flat ribbon cable may be accommodated in a deflected manner in the cylinder-envelope shaped configured plug-in guide 51 of the plug-in unit 50 and/or accommodated in a twisted manner by means of the slot 52, which is oriented parallel to the drive axis of rotation 11. In other words, the cylinder-envelope shaped configured plug-in guide 51 with a slot 52 extending parallel to the drive axis of rotation 11 may guide the flat ribbon cable to the drive 10 with traction relief and with a rotation compensation.

(41) Finally, FIG. 6 shows an inventive system 110 for at least partially automatically actuating a door leaf 101, including: a guiding device 200 in the shape of a guiding rail 201 or a rotational bearing 202 for a guiding reception of a casing element 20 at a door casing 102, and a device 100, which may be embodied as described above.

(42) The inventive device 100 and the inventive system 110 include many advantages, such as simple structure with few structural components, an inexpensive, simple and comfortable mounting, an expanded and enhanced functionality, and a high-quality appearance of the device, as well as a high protection against manipulation.

(43) The preceding description of the FIGS. 1 to 6 describes the present disclosure exclusively on the basis of examples. Obviously, individual features of the embodiments, as long as they are technically reasonable, may be freely combined with each other without departing from the scope of the present disclosure.
