Description

Driving device

Technical Field

The invention relates to a drive device for a wing of a window or flap, comprising at least one drive for moving the wing relative to a fixed chamber frame by means of flexible pulling and pushing elements, wherein the drive comprises connecting wires connected to the drive for the supply and/or actuation thereof; and the drive means has a fixing structure, in particular a bracket, for fixing the drive to the wing or the bore frame.

Background

Such drive devices are known in principle. In the drive devices of the prior art, it has been proposed to connect relatively long connecting lines to the drive, for example, by soldering or screwing the connecting lines to the drive. The connection leads are used to power and/or operate the drive and are typically up to 2m long.

For maintenance purposes, it has proven to be problematic that the entire connecting line has to be replaced together in order to disassemble the drive, which has proved difficult, in particular when the connecting line is installed in a wing or a box, or that the housing accommodating the drive has to be opened first in order to reach the connection point of the connecting line on the drive in order to disengage the connecting line. Both modes of operation are very complex.

Disclosure of Invention

The object of the present invention is therefore to provide a drive which can be more easily repaired and in particular in which the drive can be more easily replaced.

This object is achieved by a drive device having the features of claim 1, and in particular by an electrical connection means which is separate from the drive and comprises a supply interface for electrically connecting the connection means to a power supply and/or a control unit being arranged on the fastening structure, and having a drive interface which is electrically connected to the supply interface, by means of which drive interface the drive is electrically connected to the connection means via its connecting lines.

The invention is based on the idea that the drive is not directly connected to the power supply and/or the control unit via its connecting lines, but rather to a separate electrical connection which is connected in-between the interface and the power supply and/or the control unit and which is itself electrically connected to the power supply and/or the control unit.

The electrical connection is arranged on a fixing structure provided for fixing the drive and is thus located in the vicinity of the drive. Since the driver is not directly electrically connected to the power supply and/or the control unit, but only to the connection means, a shorter connection wire can be used than a connection wire directly connecting the driver to the power supply and/or the control unit in order to bridge a short distance between the electrical connection means and the driver. Thus, in order to disassemble the drive, it is no longer necessary to completely disassemble the connection wires connecting the drive with the power supply and/or the control unit together. Instead, only the connecting wires connecting the drive and the connecting means need to be disconnected from the connecting means, thereby simplifying the replacement and/or repair of the drive as a whole. The connecting wires connecting the driver and the connecting structure may for example have a length of between 2 and 10cm, preferably a length of between 3 and 7 cm. Particularly preferably, the length of the connecting wire is 5cm.

Advantageous embodiments of the invention can be inferred from the dependent claims, the description and the drawings.

According to a particularly simple embodiment of the drive, the supply and/or drive interfaces of the electrical connection are each designed as a connection bushing or connection interface, in particular, the supply and drive interfaces are electrically connected to one another by means of a cable. However, the electrical connection can also be formed on a circuit board with integrated conductors, wherein the integrated conductors electrically connect the supply interface and the drive interface.

The pulling and pushing element is preferably tensile and compressive and is constructed flexibly in one plane. For example, the pulling and pushing element can be constructed in the form of a chain or a belt. The pulling and pushing element can thus be accommodated in the housing accommodating the drive as space-saving as possible, as a result of which an as compact as possible construction of the drive device as a whole is obtained. The pulling and pushing element is moved out of the housing or into the housing for moving the window or flap.

Preferably, the electrical connection means is not only configured separately from the driver but also from the fixing structure. Thus, the electrical connection mechanism can also be easily removed for maintenance purposes or replacement.

The electrical connection, the driver and the fastening structure can be arranged with respect to one another in a space-saving manner such that the driver is arranged on a side of the fastening structure and the electrical connection is arranged on a side of the fastening structure facing away from the driver such that the fastening structure is arranged between the driver and the connection.

In order to achieve a particularly simple construction of the drive, the connecting leads of the drive can be connected to the electrical connection in a reversibly releasable manner. Preferably, the connecting line is attached to the electrical connection by means of a plug connection, a clamping connection or a snap connection. Simple assembly can be achieved using plug connectors, clamping connectors or snap-lock connectors.

The supply lines connecting the connection to the power supply and/or control unit are likewise connected or connectable to the electrical connection in a reversibly releasable manner, for example by means of a plug connection, a clamping connection or a snap connection. In principle, the supply line can also be connected to the electrical connection in other ways. For example, the supply line can be soldered or screwed to the electrical connection.

According to an advantageous embodiment of the drive device, the fastening structure can be embodied in the form of a bracket, which comprises a first holding element and a second holding element. The retaining elements are used to house the driver between itself. For this purpose, the holding elements are preferably spaced apart from one another in the longitudinal extension of the drive. Preferably, the holding elements are designed separately from one another, so that the receiving area of the fastening structure can be matched to the dimensions of the drive. The circuit board supporting the electrical connection can also be used to support the holding elements of the carrier, in particular, spaced apart from one another according to the dimensions of the drive.

The drive interface of the connection mechanism may be arranged on the first holding element or on the second holding element. In principle, however, a drive interface can also be provided on each holding element. In this way, the drive can be fastened to the fastening structure in a first orientation or in a second orientation rotated by 180 °.

Sometimes more than one actuator may be required, for example, due to an unfavorable leverage ratio or for moving a narrow, elongated or heavy wing or flap. In order to electrically connect a plurality of drives, it has been proposed in the drive arrangements to date to connect the drives to a power supply and/or a control unit via their respective connecting lines at the central junction box. In this case, this also proves to be problematic when the connecting lines are fixedly connected to the respective drive, since each drive must be connected to the central terminal box via its connecting line. In an alternative solution, it is provided that the current forwarding and/or signal forwarding takes place in the respective driver to the further driver. The conductors are routed within the drive, thereby increasing the structural effort of the drive.

In order to avoid the disadvantages, according to one advantageous embodiment of the drive, it is provided that the drive has an expansion interface which is electrically connected to the supply interface for the purpose of electrically connecting to the other drive. As with the electrical connection, the expansion interface may be configured separately from the driver. The electrical lines connecting the expansion interface and the supply interface can also be formed separately from the drive. The advantage obtained thereby is that a costly feed-through of electrical lines inside the drive can be dispensed with, whereby the drive has a compact construction.

The drive can be expanded modularly if necessary by means of the expansion interface, wherein the module comprises a drive and the electrical connection as described herein and the fastening as described herein.

Preferably, the electrical connection mechanisms of the two drivers are connected to each other via an extension wire in such a way that: one end of the extension wire is connected to an extension interface of the connection of one of the drives and the other end of the extension wire is connected to a supply interface of the connection of the other drive. It can furthermore be provided that the two drives are electrically connected to one another by means of an extension line, which connects the extension interface of one drive to the supply interface of the other drive.

The extension cord can be connected to the extension interface and/or the supply interface in a reversibly releasable manner, for example by means of a plug connection, a clamping connection or a snap connection. Alternatively, the extension wire may be fixedly soldered or screwed to at least one of the interfaces. According to a particularly simple embodiment, the extension conductor can be designed as a cable, in particular as a ribbon cable.

According to an advantageous embodiment of the drive device, the supply interface is arranged on the first holding element and the expansion interface is arranged on the second holding element. This makes it possible to expand the drive device in one direction. However, it is also possible to provide an expansion interface on each of the two holding elements, so that the drive can be expanded in both directions.

Preferably, the supply interface and the expansion interface are electrically connected to each other via a connection wire. The connecting line can be embodied in the form of a cable, in particular a ribbon cable. This embodiment is advantageous in particular in the case of long drives. In the case of short drivers, the connecting conductors can be configured as conductors integrated into the circuit board. The circuit board may additionally also have integrated conductors which electrically connect the supply interface with the drive interface.

For an easy-to-assemble design of the drive device, the drive device may comprise a mounting plate, which supports the fastening structure and the electrical connection. The fastening structure and the electrical connection can thus be first preassembled on the wing or the bezel by means of the mounting plate. The driver can then be fixed to the fixed structure in a simple manner.

A particularly advantageous embodiment of the drive provides that the fastening means and the electrical connection means of the two drives are arranged on a common mounting plate.

The mounting plate may also form part of the housing of the drive device. In particular, the mounting plate can be used as a cover for the wiring of the drive device.

According to an advantageous embodiment of the drive device, a power supply element for the drive is arranged on the fastening structure, in particular on one of the two holding elements of the carrier. Thus, for example, a standardized 24V drive can be operated at a voltage of 230V. Furthermore, the power supply member may be disposed on the mounting plate.

Detailed Description

The drive device shown in the figures is used to move a window or a flap, not shown, with respect to a fixed chamber frame, also not shown, by means of one drive or two drives, respectively. For this purpose, each of the drives has a flexible pulling and pushing element, not shown further, which may be designed in the form of a chain or a belt.

In order to convert the movement of the drive into a movement of the wing, the outer ends of the pulling and pushing elements are connected to a transmission mechanism 4 which is in turn fixed to the wing when the drive is mounted on the chamber frame or which is fixed to the chamber frame when the drive is mounted on the wing.

Each of the drives shown in fig. 1a and 3a comprises a drive 6 with a cover plate and two end caps 8, which, viewed in the longitudinal direction of the drive, each form a closure of the drive 6 at its ends facing away from one another. For better illustration, the actuator 6 or actuators and the cover plate are not shown in the detail views of fig. 1b, 1c, 2b and 3 b.

The construction of the drive device according to the first embodiment will now be described in more detail with reference to fig. 1a to 1 c.

For mechanical fastening to the wing or sash, the driving device comprises a fastening structure 10. The fastening structure 10 is also used to accommodate the drive and is configured for this purpose in the form of a bracket. The carrier 10 includes a first holding element 12a and a second holding element 12b separate from the first holding element 12 a. In fig. 1c, the first holding element 12a is schematically shown by a dashed line.

The holding elements 12a, 12b are each L-shaped and each have two legs 14, 16. Specifically, each retaining element 12a, 12b has one fixed leg 14 and one retaining leg 16. The fixing legs 14 are used to fix the drive device to the wing or the chamber frame. The retaining legs 16 are spaced apart from each other in the longitudinal extension of the drive device and serve to fix the drive 6. The distance between the holding legs 16 is oriented according to the dimensions of the driver 6 and dimensioned such that the assembled driver 6 is accommodated between the holding legs 16. Furthermore, the end cap 8 can be inserted onto the holding leg 16, so that the drive device has the mentioned appearance in the assembled state.

For fastening the drive device to the wing or the chamber frame, a pair of first bores 18 are provided in the fastening leg 14, respectively, which are each intended to receive a fastening element, for example a screw. The retaining leg 16 has a pair of second holes 20 through which fixing elements, such as screws, can be inserted or screwed for connecting the driver 6 with the retaining elements 12a, 12b. Depending on the application, the holding elements 12a, 12b may also have a smaller number of holes or further holes for fixing the driver 6 or the drive device.

An electrical connection 22, which is formed separately from the carrier 10 and from the drive 6, is arranged on the carrier 10. As can be seen from an overview of fig. 1a and 1b, the electrical connection 22 is arranged on the side of the holding elements 12a, 12b facing away from the side for accommodating the drive 6. In other words, in the assembled state of the drive device, the drive 6 is arranged on the side of the fastening structure 10, and the electrical connection 22 is arranged on the side of the fastening structure 10 facing away from the drive 6. Specifically, the electrical connection 22 is formed on a circuit board 24 which is mounted on the side of the first holding element 12a facing away from the driver 6.

The electrical connection 22 has a supply interface 26 (fig. 1 c) to which supply lines 28 for electrically connecting the connection 22 to a power supply and/or a control unit are connected. The supply line 28 can be soldered, screwed or mounted on the supply connection 26 via a plug connection, a clamping connection or a snap connection.

In addition, the electrical connection 22 has a drive interface 30 that is electrically connected to the supply interface 26. In the present exemplary embodiment, the drive interface 30 and the supply interface 26 are electrically connected to one another by means of wires integrated in the circuit board 24.

The drive interface 30 is used to connect the driver 6 via its connection leads to the electrical connection 22. The connecting lines of the drive can be connected to the drive interface 30 of the electrical connection 22 in a reversibly releasable manner, for example by means of a plug connection, a clamping connection or a latching connection. Thereby, the connecting wires of the driver 6 can be disconnected from the electrical connection 22 in a simple manner, so that the driver 6 can be easily detached.

As already mentioned, the electrical connection 22 with the supply interface 26 and the drive interface 30 is arranged on the first holding element 12 a. In addition to the drive interface 30 arranged on the first holding element 12a, a further drive interface 30 may also be provided on the second holding element 12b in order to enable the mounting of the driver 6 in a first orientation or in a second orientation rotated 180 °.

Furthermore, the drive has an expansion interface 32. The expansion interface 32 is used to expand the drive device with an additional drive. For this purpose, the drivers 6 are interconnected via extension wires 38, as will be explained in more detail below in connection with fig. 3a and 3 b. Expansion interface 32 may also be used to electrically connect the drive device with another drive device. The extension line 38 connects the extension interface 32 of one drive to the supply interface 26 of the other drive.

The expansion interface 32 is provided on a circuit board 24' separate from the circuit board 24 of the connection structure 22. The printed circuit board 24' with the expansion interface 32 is arranged on the side of the carrier 10 facing away from the drive 6, to be precise on the second holding element 12b.

The expansion interface 32 is electrically connected to the supply interface 26 via a connection line 34. In the drive according to the first embodiment, the connecting line 34 is embodied in the form of a cable 34, more precisely in the form of a flat cable 34. A ribbon cable 34 connects the circuit board 24 of the connection mechanism 22 with the circuit board 24' having the expansion interface 32. At least one end of the cable 34 is connected to one of the circuit boards 24, 24' in a reversibly releasable manner, for example via a plug connection, a clamping connection or a snap connection. Furthermore, at least one end of the cable 34 may be fixedly connected, e.g., fixedly soldered, to one of the circuit boards 24, 24'.

With reference to fig. 2a and 2b, a drive device according to a second embodiment will now be described, which differs from the drive device according to the first embodiment in that the electrical connection 22 and the expansion interface 32 are arranged on a common circuit board 24 ". The connection lines 34 connecting the supply interface 26 with the expansion interface 32 are designed here as lines integrated into the circuit board 24 ". The common printed circuit board 24″ also supports the holding elements 12a, 12b of the carrier 10, which are shown schematically in fig. 2b by dashed lines.

The third embodiment of the drive device shown in fig. 3a and 3b is based on the first embodiment of the drive device shown in fig. 1b and 1 c. The drive according to the third embodiment has two drives, as can be seen by means of the two transmission mechanisms 4. However, the number of drivers 6 is not limited to two. Thus, the drive device may also have more than two drives.

For fixing the drive, a carrier 10 is provided, as already described above in connection with the first embodiment of the drive. In addition to the carrier 10, an electrical connection 22 is provided for each drive 6, which is connected to the expansion interface 32 in each case in such a way as described hereinabove in connection with the first embodiment of the drive. In principle, the electrical connection 22 and the expansion interface 32 can also be connected to one another in the manner described above in connection with the second embodiment of the drive device.

As can be seen by means of fig. 3b, the drivers 6 are electrically connected to each other via the already mentioned extension wires 38. One end of the extension wire 38 is connected to the extension interface 32 arranged on the second holding element 12b of the first bracket 10. The other end of the extension wire 38 is connected to the supply interface 26 of the second electrical connection 22, which is arranged on the first holding element 12a of the second bracket 10. At least one end of the extension cord 38 can be connected to one of the interfaces 26, 32 in a reversibly releasable manner, for example via a plug connection, a clamping connection or a snap connection. Alternatively or additionally, at least one end of the extension wire 38 may be fixedly connected, e.g. fixedly soldered, to one of the interfaces 26, 32.

Both the carrier 10 and the electrical connection 22 are supported by a common mounting plate 36. The mounting plate 36 together with the cover plate and the end cap 8 form the housing of the drive.

Finally, it should be noted that the above-described drive devices may each have a power supply element, which is not shown in the figures. The power supply element is provided for matching the supply voltage to the operating voltage of the driver 6 or drivers. The power supply element is preferably arranged on the fastening structure 10 and in particular on one of the holding elements 12a, 12b of the bracket 10. The power supply member may be disposed on the mounting plate 36. Furthermore, the power supply element may also be arranged on the circuit board 24.
