Door drive in modular design

0001The present invention is directed to a door drive for driving a rotating sash of a door arrangement, the door drive being designed for mounting on a receiving body such as a door lintel, a wall or the like, having a connection module for connecting at least one connection line.

0002Door drives are known which are designed as electromechanical or electrohydraulic door drives and which require a power supply via at least one external connection line. Furthermore, external connection lines can relate to various signal lines in order to connect the door drive to a central controller that is present outside the door drive, for example in a building. Further connection lines can relate to the connection line to sensors, which are also present outside the door drive on the door arrangement. In order to reduce the number of variants of today's door drives and to qualify standardized door drives for more flexible installation, solutions are necessary to provide door drives that allow a wide variety of installation situations despite a uniform design.

0003In particular, door drives are required which are designed in the delivery state in such a way that a fitter only has to carry out simple modifications during assembly on site in order to implement the most varied of installation situations and possible uses of the standardized door drive. Special requirements relate to the design of the connection module, which represents the interface between the door drive and external devices.

0004It is therefore the object of the present invention to create a door drive which is designed for flexible installation in various installation situations.

0005The object is achieved on the basis of a door drive for driving a rotary leaf of a door arrangement according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous further developments of the invention are given in the dependent claims.

0006The invention includes the technical teaching that the connection module has at least one opening from the direction of the receiving body and from at least one lateral direction, through which connection lines can optionally be fed to the connection module.

0007The design of the connection module according to the invention further increases the flexibility with regard to the assembly of the door drive in various installation situations. In particular in the case of wall mounting or the mounting of the door drive on the door lintel, an electrical connection line can already be installed in preparation in such a way that the connection line is led out of the wall or out of the door lintel at a suitable point. If the connection module has an opening which points in the direction of the receiving body, the connection line can be passed through this opening in order to form the supply or signal connection on the inside in the connection module.

0008If, on the other hand, a connection line is laid on the outside of the receptacle in the direction of the door drive, the opening in the connection module that points in the lateral direction is used. In particular, the door drive can be installed first, so that the connection line is only attached afterwards. The opening can be used to the side. In particular, for example, the power supply can be used through the opening from the direction of the receiving body, whereas the connection lines can be used for signal supply through the opening in the lateral direction. This results in a highly flexible and variable installation of a standardized door drive, whereby it is often only possible to decide on site during installation which type of connection can be used to exclude the door drive.

0009At least one connection terminal part for establishing an electrical connection of the connection line is advantageously received in the connection module. The connection terminal part is used in particular to connect the power supply, wherein the door drive can include a mounting plate, so that the connection terminal part is mechanically received on the mounting plate. The connection terminal part can have latching projections for receiving it on the mounting plate, which snap into insertion recesses that are made in the mounting plate. To further simplify the connection between the connection line and the connection terminal part, the connection terminal part can have release buttons that can be operated manually. If the release lever is actuated, the connection cable can be inserted into the associated connection cable clamps. The release button of the connection terminal part can be designed to be spring-loaded, so that after the activation of the release button, the connection line is firmly received in the connection terminal part.

0010Advantageously, the release lever or the connection terminal part is designed so that the connection lines are simply pushed into the connection terminal part without separate actuation and in the course of this are held by the connection terminal part at least in the pull-out direction, which simplifies the connection.

0011Furthermore, at least one distribution board can be accommodated in the connection module, by means of which a variable distribution of the voltage supply is made possible at least to one power supply unit present in the door drive.

0012A connecting bridge line can be provided between the connection module and the distribution board. This enables an electrical connection to be established between the connection terminal part and the distributor board.

0013The distribution board can have a number of connection sockets into which the associated connection plugs can be inserted. The connection sockets of the distribution board can comprise a first connection socket for connection to the connection terminal part, it being possible for a further connection socket to be provided for connection to the power supply unit within the door drive. Furthermore, a third connection socket for connecting a further door drive can be present on the distribution board, so that, for example, in the case of a double-leaf door, two door drives can be supplied via just one connection line. Furthermore, an on / off switch can be provided on the distribution board in order to switch the door drive on and off manually. For this purpose, the distribution board can be accommodated in the connection module in such a way that at least the on / off switch extends in the direction of the outside of the connection module.

0014According to a further advantageous embodiment of the door drive, the connection module can be positioned on the mounting plate via catch pins and preferably held in a self-retaining manner. The self-retaining mount relates to the mounting of the door drive on the mounting plate in an intermediate assembly step. The fitter can attach the modules of the door drive, which in particular include the connection module, to the mounting plate using the catch pins. Subsequently, no manual holding of the door drive on the mounting plate is necessary, so that a fitter can attach the final screw connection between the door drive and the mounting plate in a simplified manner. In particular, the door drive can consist of individual modules, the connection module representing one of the modules forming the door drive.

0015Furthermore, the connection module is advantageously designed in such a way that it projects beyond the mounting plate in the lateral direction. This has the advantage that a free supply of the connection line from the direction of the receiving body, ie from the direction of the mounting plate, to the connection terminal part is created. The mounting plate can be designed as a flat sheet metal component with an elongated extent, the direction of extent of the sheet metal component corresponding to the longitudinal extent of the door drive. If the mounting plate is made correspondingly shorter, it ends within the connection module, and the connection terminal part can be attached to the end of the mounting plate. For example, if the connection line penetrates the receiving body in the area between the end of the mounting plate and the end of the body of the connection module, the connection between the connection line and the connection terminal part is particularly simple. In particular, the connection module has an interior space that offers sufficient storage space for an excess cable length.

0016At least one strain relief means can be provided on the connection module in order to create a mechanical accommodation for the connection line in the door drive. The strain relief means can in particular be formed by a clamping element which is inserted in a clamping element receptacle on the connection module. The clamping element receptacle forms a type of insert through two side rails into which the clamping element can be pushed. If the connection line is passed through the clamping element, this can then be screwed to the connection module, whereby the connection line is clamped at the same time. This creates strain relief so that when there is a mechanical tensile load in the connection line, the force is absorbed via the clamping element and the electrical connection between the connection line and the connection terminal part is not stressed. The strain relief means is attached to the underside of the connection module and is used in particular to relieve strain on a connection line that is fed to the connection module via the lateral direction.

0017Furthermore, a strain relief element can be provided for arrangement on the connection terminal part. The strain relief element can have a U-shaped section for form-fitting use in the connection terminal part, to which a T-shaped or H-shaped section is connected, which is used for the clamping connection of the connection bridge line and / or the connection line. The connecting bridge line and / or the connecting line can be braced with the T- or H-shaped section of the strain relief element using a cable tie.

0018The geometric configuration of the connection module according to the invention forms a shell or a basket which is designed to form a cavity and has thin walls and is produced, for example, by a plastic injection molding process, from thermosetting plastic, by a deep-drawing or metal die-casting process. The formation of plastic has the advantage of the electrical insulation effect of the connection module. In particular, a slide-in or clip-in frame for holding the distribution board can be provided on the connection module. The shell-like or basket-like shape of the connection module forms, in abstract form, a cube that represents an end-side section of the cuboid door drive. The door drive comprises a signal connection board, which is used in particular to connect the connection lines that are necessary between the door drive and external sensors or, for example, an external controller. The signal connection board is clipped onto the top of the connection module by means of associated latching means for holding reception. The signal connection board is advantageously U-shaped or horseshoe-shaped. The central cutout formed by the U-shape or by the horseshoe shape corresponds to an opening on the top side within the basket-like connection module. If the signal lines are routed through the opening from the direction of the receiving body or through the opening from the lateral direction into the interior of the connection module, then the corresponding connection lines can be connected to the associated connection terminals attached to the signal connection board. As a result, the connection lines can be fed to the connection terminals in a simple manner through the opening at the top. The connection terminals can comprise screw connections that are easily accessible by a fitter, since these are directed upwards, ie in the direction from the mounting plate to the connection module, and can consequently be easily operated when the connection module is already installed.

0019Furthermore, it is provided that the connection module has a support area for supporting the signal connection board, with a partial surface of the support area being formed on a support part which is foldably arranged on the connection module. Before the signal connection board is clipped onto the connection module, the support part can be opened in order, for example, to produce the connections to the connection terminal part that are present on the underside. Furthermore, the distribution board can be pushed into the slide-in or clip-in frame below the support part. If the support part is then folded over and latched so that the partial surface forms a plane with the rest of the support surface of the signal connection board, the slide-in or clip-in frame is closed in such a way that the distribution board is firmly inserted in the connection module.

0020In order to create a continuation of the signal connections, which are led into the door drive via the connection terminals on the signal connection board through the external connection lines, a ribbon cable can be provided which leads the signal connections in the direction of a control unit within the door drive. The ribbon cable can be laid above the individual modules forming the door drive. According to an advantageous further development of the connection module, at least one cable guide means is located on the upper side in order to ensure a fixed route of the ribbon cable within the door drive.

0021In addition to the connection module, the door drive can have a drive module or a main module that includes a drive unit. This can be mechanically self-retaining connected to the connection module via at least one slide-on projection on the drive unit, with at least one slide-on recess which is complementary to the slide-on projection and into which the slide-on projection can be inserted. Furthermore, the connection module can be connected to the drive unit in a self-retaining manner by a latching means comprising at least one latching projection. Consequently, at least the connection module can form a mechanical unit with the main module or drive module, which can be handled individually by the fitter and placed on the mounting plate.

0022Furthermore, it can be provided that the drive unit has a shaft passage for a door drive output shaft to pass through. The door drive output shaft can be led out of the drive unit on a first and / or on a second side of the door drive. The connection module can protrude beyond the drive unit over the area of ​​the shaft passage, wherein a pocket-like design can be incorporated in the connection module, through which the door drive output shaft runs through the wall of the connection module.

0023Advantageously, a first closure element is optionally provided, which can be inserted into the recess, so that a shaft lead-through for the door drive output shaft is formed in the connection module. If the door drive output shaft is led out of the door drive on the opposite side, a second closure element can be provided which can be inserted into the recess in the connection module and which completely closes it. The second closure element consequently forms a type of blind plug, whereas the first closure element forms a circular passage together with the pocket-like recess.

0026<figref idref="f0001">Figure 1</figref> shows an embodiment of the connection module 1 according to the invention from an underside direction. From this underside direction, the connection module 1 can be connected to the mounting plate 8 via catch pins 9. A connection terminal part 5 for establishing an electrical connection connection of the connection line 2 is received within the connection module 1. According to the invention, the connection line 2 can be fed to the connection module 1 either from the direction of a receiving body, represented by an arrow 3, or from a lateral direction 4. By way of example, the connection line 2 is shown as a network connection, wherein the connection line 2 can also include signal lines, for example to sensors or to a central controller. The illustration shows a supply of the connecting line 2 from direction 3 of the receiving body. The lateral direction 4 shown in dashed lines represents an alternative feed direction of the connecting line 2.

0027The connection terminal part 5 shown has latching projections 34 via which the connection terminal part 5 is connected to the mounting plate 8 and is thereby at least arranged in a manner that is secure against rotation, in that the latching projections 34 engage in latching recesses 35 that are present in the mounting plate 8. Furthermore, the mounting plate 8 has an electrical connection point 36, which is used to make electrical contact with a grounding contact within the connecting line 2.

0028Additionally or alternatively, the connection terminal part 5 is preferably fastened to the mounting plate 8 in the delivery state in a detachable manner, for example by means of screwing, or non-detachably, for example by means of riveting.

0029<figref idref="f0002">Figure 2</figref> shows a perspective view of the connection module 1 from a direction below, both the direction 3 to the receiving body and the side direction 4 being indicated. According to this illustration, the connection line - not shown for the sake of simplicity - can be fed to the connection module 1 through the lateral direction 4. For this purpose, a strain relief means 10 is provided, which can be used for mechanical strain relief of the connection line and is present on the body of the connection module 1. The strain relief means 10 comprises a clamping element 11 which is fastened to the connection module 1 by means of a screw 47 shown as an example. The connection line can extend through the clamping element 11, so that a mechanical tensile load in the connection line is absorbed by the clamping element 11 and is not transmitted to the connection terminal part 5. A connection bridge line 7 is provided between the connection terminal part 5 and a distribution board 6 present in the connection module 1 in order to continue the electrical supply through the external connection line from the connection terminal part 5 to the distribution board 6.

0030<figref idref="f0002">Figure 2a</figref> FIG. 2 shows a detailed view of the strain relief means 10 according to FIG. 2. The clamping element 11 and the screw 47 are not shown here, whereby it can be seen that a clamping element receptacle 12 is provided in the body of the connection module 1. The clamping element receptacle 12 is designed like a slide-in unit, so that the clamping element 11 can be pushed between two slide-in strips and is screwed in the middle. As a result, the mechanical load that is transmitted from the connection line to the clamping element 11 can be passed on to the connection module 1.

0031<figref idref="f0002">Figure 3</figref> shows an enlarged perspective individual view of the arrangement of the connection bridge line 7 between the connection terminal part 5 and the distributor board 6. The connection terminal part 5 is shown in a mounted arrangement on the mounting plate 8. The connecting bridge line 7 can be manually released from the connecting terminal part 5 by means of the unlocking lever 28 or can be inserted into it in a fixed manner. The connection terminal part 5 is advantageously designed in such a way that the release lever 28 only has to be actuated in order to be able to pull the respective line out of the connection terminal part 5. I. E. when connecting the connecting line 7, the respective line only needs to be pushed into the connecting terminal part 5; it is locked automatically by the connection terminal part 5. At the end, the connection bridge line 7 has a connection plug 30 which can be plugged into a complementary connection socket 29 on the distribution board 6. The connection sockets 29 are provided in triplicate on the distribution board 6, so that a further connection socket 29 is used to connect the power supply to a power supply unit within the door drive, the third connection socket 29 being provided for supplying power to, for example, a further door drive, which can be part of a closing sequence control device, for example . There is also an on-off switch on the distribution board 6, by means of which the door drive can be switched on and off.

0032Power supply conductors of the connecting line 2, not shown here, are, as in FIG <figref idref="f0002">Figure 3</figref> shown, plugged into connecting line terminals 37, which are preferably arranged in the connecting terminal part 5 next to the respective conductor of the connecting bridge line 7, with an electrical coupling between the respective adjacent conductors of the connecting lines 2, 7 through the connecting terminal part 5.

0033<figref idref="f0003">Figure 4</figref> shows a further perspective view of the arrangement of the connection terminal part 5 on the mounting plate 8, which is shown with the catch pins 9 mounted thereon. Furthermore, the release buttons 28 in the connection terminal part 5 are shown again, so that when the release buttons 28 are operated manually, the connection bridge line 7 and / or the connection line 2 can be removed from the connection terminal part 5. In order to also provide mechanical strain relief between the connecting bridge line 7 and the connecting terminal part 5, a strain relief element 13 is shown, which is inserted into the connecting terminal part 5 in a form-fitting manner. The connecting bridge line 7 is braced to the strain relief element 13 via a cable tie 38, shown as an example, so that a mechanical tensile load on the connecting bridge line 7 with the connector 30 is diverted into the strain relief element 13. Possible embodiments of the strain relief element 13 are shown in FIG<figref idref="f0003">Figure 5</figref> shown in more detail.

0034Also shows <figref idref="f0003">Figure 4</figref> the connection of a neutral conductor or a grounding line 2a of the connection line 2 to the mounting plate 8.

0035As <figref idref="f0003">Figure 4</figref> shows, the edges of the strain relief element 13 can be beveled or rounded.

0036<figref idref="f0003">Figure 5</figref> shows a first and a second embodiment of the strain relief element 13. The strain relief element 13 has a U-shaped section 14 for form-fitting insertion into the connection terminal part 5 and a T- or H-shaped section for the clamping connection of the connection bridge line 7 and / or the connection line 2, for example by means of a cable tie 38. The strain relief element 13 is made in one piece and can be produced as a stamped component from a sheet metal material. In order to avoid any electrical short circuits, for example between the conductors of the connecting bridge line 7, the strain relief element 13 is preferably made of plastic. The connection terminal part 5 can have a central web in the manner of a luster terminal, which separates the two poles of the connection line or the connection bridge line 7 from one another. The central web can be gripped around by the U-shaped section 14, preferably in a clamping manner. The T- or H-shaped section 15 has two indentations into which the cable tie 38 can be inserted. In order to create a better latching of the strain relief element 13 in the connection terminal part 5, latching lugs 39 pointing into the U-shaped section 14 can be provided so that the clamping effect can be dispensed with or the holding force resulting therefrom can be increased or supported.

0037<figref idref="f0004">Figure 6</figref> shows the connection module 1 in a perspective view from the direction of the top. A signal connection board 16 is attached to the top of the connection module 1, which is designed in the manner of a basket, which is locked to the connection module 1 via latching means 17. The signal connection board 16 is U-shaped or horseshoe-shaped and has a plurality of connection terminals 33 on the top. Corresponding to the U-shaped recess within the signal connection board 16, there is an opening 32 on the upper side in the connection module 1 through which the signal lines can be fed to the connection terminals 33.

0038The connection module 1 also has a support part 19, which forms a partial surface 18 for supporting the signal connection board 16 on the connection module 1 and is shown in an unfolded form by way of example only. When assembling the connection module 1 and when establishing the electrical connections, in particular the power supply, the support part 19 can remain in the open position in order to allow access to the inside of the connection module 1. Once the internal connections have been established and, in particular, the distributor board is inserted into the connection module 1, the support part 19 is folded over so that its partial surface 18 is part of a total support surface of the signal connection board 16. During the following work on the signal connections via the connection terminals 33, the high-voltage components within the connection module 1 are consequently covered by the support part 19. Furthermore, the connection module 1 has a cable guide means 20, which is designed as a support surface and is used to guide a ribbon cable that extends between a ribbon cable connector 40 in the form of a plug or socket and a control unit present in the door drive, the ribbon cable not in the figure is shown.

0039The signal connection board 16 is preferably designed with display elements 48, for example in the form of LEDs and / or LCD displays, which display, for example, operating and / or malfunction states of the door drive 1, the pending maintenance and the like. The display elements 48 are preferably visible from the outside when the cladding is on.

0040<figref idref="f0005">Figure 7</figref> shows a further perspective view of the top of the connection module 1, it being made clear that the connection module 1 is designed like a basket or a bowl and is produced, for example, by a plastic injection molding process or a metal die casting process. All components are clipped in and on the connection module 1 or pushed in or locked into place by mechanical joints. In particular, the support part 19 is preferably connected in one piece to the connection module 1 via a film hinge. It is also clear that when the support part 19 is folded down, the partial surface 18 with the support surface 45, which is present on the side of the latching means 17, forms the total support surface for the in<figref idref="f0005">Figure 7</figref> Forms signal connection board 16, not shown. If the support part 19 is folded over in order to latch onto the base body of the connection module 1, latching recesses 41 are provided on this, into which latching lugs 42, which are integrally formed on the support part 19, can engage.

0041<figref idref="f0006">Figure 8a</figref> shows a side view of the connection module 1 with a pocket-like recess 26. The pocket-like recess 26 is located in a body portion of the connection module 1, which is an existing in the door drive, in <figref idref="f0006">Figure 8</figref> drive unit 21, not shown, can protrude. A door drive output shaft, which has to pierce the wall of the connection module 1, can be led out of the drive unit 21. Door drives often have drive units from which the door drive output shaft is optionally led out on a first and / or a second side of the door drive. Consequently, the need arises to provide a closure element 27a and / or 27b which either enables the shaft to pass through or constitutes a blind plug in order to completely close the pocket-like recess 26. Consequently, the closure element 27a has a contour which, when used in the pocket-like recess 26, forms a preferably circular hole within the wall of the connection module 1. If the door drive output shaft is not led out on the side of the connection module 1 shown, the closure element 27b is inserted into the pocket-like recess 26 without the shaft lead-through and latched into it via latching recesses 43.

0042If the output shaft emerges from the drive unit 21 on both sides, a closure element 27a is preferably attached to the side of the connection module 1 to which the door leaf is connected, for example via a linkage. Accordingly, a closure element 27b, which covers the shaft passage in the connection module 1, is preferably attached to the opposite side of the connection module 1.

0043As a result, the output shaft can be accessed by simply pulling off the closure element 27 without having to pull off an entire cover panel, which is tedious.

0044In the case of a so-called tandem solution, in which two door drives are operatively coupled to one another, only locking elements 27a are attached to the door drive to which both the door leaf and the other door drive are directly connected.

0045<figref idref="f0006">Figure 8b</figref> shows another variant of closure elements 27a, 27b. The closure element 27a is similar to the closure element 27a of FIG<figref idref="f0006">Figure 8a</figref> educated. In the case of the cover of the output shaft of the door drive 1, on the other hand, two cover parts are used in this embodiment, on the one hand the closure element 27a and on the other hand a closure element 27b, which is preferably circular in cross-section such that it forms an output shaft cover together with the closure element 27a results, which is similar to the closure element 27b of<figref idref="f0006">Figure 8a</figref> is shaped. The closure elements 27a, 27b can be designed in such a way that they are plugged together to form an entire cover part before being placed on the connection module 1. Alternatively, the closure elements 27b and 27a are pushed onto the connection module 1 one after the other in the sequence. As on the right in<figref idref="f0006">Figure 8b</figref> As shown, the locking elements 27a, 27b preferably form an output shaft cover with a shape similar to the locking element 27b in FIG <figref idref="f0006">Figure 8a</figref>.

0046In order to form a respective output shaft cover, the closure elements 27a, 27b are moved in direction 49, that is to say in <figref idref="f0006">Figure 8a</figref> in the direction of the sheet, placed on the connection module 1.

0047The closure element 27b is preferably designed in accordance with the previously described ones and placed on the output shaft of the door drive 1 itself. In this case, only fastening means for the closure element 27a are required on the connection module 1.

0048The closure element 27b can advantageously be removed from the connection module 1, for example levered off, when the closure element 27a is attached. The advantage is that the closure element 27b can be (dis) installed at any time when the door drive 1 is installed and provided with a cladding, in order to expose or cover the respective end of the output shaft of the door drive 1. As a result, a fitter does not have to pay attention from the outset which closure element 27a, 27b he has to put on or remove where before installing the door drive 1, which increases the ease of installation.

0049This embodiment has the advantage that more identical parts can be used and simpler shapes can be selected for special parts, that is to say the closure element 27b, and less material is required.

0050In both versions, the first closure element 27a exposes the respective end of the output shaft of the door drive 1, thus creating a shaft lead-through for the output shaft. The second closure element 27b, on the other hand, covers the output shaft from the outside.

0051Finally shows <figref idref="f0007 f0008">Figure 9</figref> the arrangement of the connection module relative to the drive unit 21 of the door drive in two perspective views. On the drive unit 21 there are push-on projections 22 which can be pushed into push-on recesses 23 within the connection module 1. The arrangement of the push-on projections 22 corresponds to the push-on recesses 23, so that the connection module 1 can be pushed onto the drive unit 21, preferably by clamping, from a joining direction, represented by the arrow 44. In order to preferably latch the connection module 1 to the drive unit 21, latching means are provided which are implemented, for example, by latching projections 24. The one latching projection 24 shown as an example latches behind a latching surface 46 formed on the drive part 21, that is to say it engages behind in the assembled state. If the connection module 1 is locked to the drive unit 21, both parts 1 and 21 form an object that can be handled individually by the fitter. In addition, the drive unit 21 shows the shaft passage 25 for leading out the door drive output shaft, not shown, which can extend out of the connection module 1 through the pocket-like recess 26 within the connection module 1 and is used for the mechanical connection of the rotating sash of the door arrangement via a corresponding linkage.

0052The embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details, spatial arrangements and method steps, can be essential to the invention both individually and in the most varied of combinations. In particular, the individual components of the connection module 1 and related components are latched to the connection module 1. No connecting elements are required to make the individual connections. The latching relates in particular to the distribution board 6, the signal connection board 16 and the locking elements 27a and 27b, which can be attached to the connection module 1 essentially without any further tools. Furthermore, the latching relates to the connection module 1 with every further component of the door drive, which can relate to the drive unit 21, for example.

0053Instead of or in addition to the latching connections described, with the exception of the latching connections provided on the signal connection board 16, other holding mechanisms such as clamps, screwing and the like are possible.

0054The connection sockets and connection plugs described can be replaced, for example, by continuous lines or cables.
