Description

The invention relates to a drive arrangement for a sash of a window or a flap, with at least one drive for moving the sash relative to a fixed window frame by means of a flexible pull and push element, the drive having a connecting line connected to the drive for its power supply and/or control includes, and with a fastening structure, in particular a console, for fastening the drive to the wing or the frame.

Such a drive arrangement is known in principle. In previous drive arrangements, it has been provided that a comparatively long connection line is connected to the drive, for example by the connection line being soldered or screwed to the drive. The connection cable is used for power supply and/or control of the drive and is usually up to 2 m long.

For maintenance purposes, it has turned out to be problematic that either the entire connection line has to be replaced to remove the drive, which is particularly difficult if the connection line is installed in the sash or the frame, or the connection line has to be loosened only a housing accommodating the drive has to be opened in order to get to the connection point of the connecting cable on the drive. Both procedures are extremely complex.

One object of the invention is therefore to create a drive arrangement which is easier to maintain and in particular in which a drive can be replaced more easily.

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

The invention is based on the idea of not connecting a drive directly to a power source and/or control unit via its connection line, but using a separate electrical connection means interposed between the connection and the power source and/or control unit, which in turn is connected to the power source and/or is electrically connected to the control unit.

The electrical connection means is arranged on a fastening structure provided for fastening the drive and is therefore located in the vicinity of the drive. Since the drive is not electrically connected directly to the power source and/or control unit, but only to the connecting means, a shorter connection line can be used in comparison to a connecting line directly connecting the drive to the power source and/or the control unit, in order to achieve the short distance to bridge between the electrical connection means and the drive. In order to remove the drive, a connection line connecting the drive to the power source and/or the control unit no longer has to be completely removed at the same time. Instead, it is only necessary to detach the connection line connecting the drive and the connecting means from the connecting means, which makes it easier to replace and/or maintain the drive overall. The connection line connecting the drive and the connecting means can, for example, have a length between 2 and 10 cm and preferably between 3 and 7 cm. The length of the connection line is particularly preferably 5 cm.

Advantageous embodiments of the invention can be found in the dependent claims, the description and the accompanying drawings.

According to a particularly simple configuration of the drive arrangement, the supply connection and/or the drive connection of the electrical connection means can each be designed as a connection socket or connection terminal, in particular the supply connection and the drive connection being electrically connected to one another by means of a cable. However, the electrical connection means can also be formed on a printed circuit board with an integrated line, the integrated line electrically connecting the supply connection and the drive connection.

The pull and push element is preferably designed to be resistant to tension and pressure and flexible in one plane. For example, the pull and push element can be designed in the form of a chain or a belt. As a result, the pull and push element can be accommodated in a housing accommodating the drive in as space-saving a manner as possible, as a result of which the overall structure of the drive arrangement is as compact as possible. The pull and push element for moving the window or flap can be extended out of the housing or retracted into the housing.

The electrical connection means is preferably designed not only separately from the drive, but also separately from the fastening structure. This also allows the electrical connection means to be easily removed for maintenance purposes or replacement.

The electrical connection means, the drive and the fastening structure can be arranged in a space-saving manner relative to one another in such a way that the drive is arranged on one side of the fastening structure and the electrical connection means is arranged on the side of the fastening structure remote from the drive, so that the fastening structure is arranged between the drive and the connection means is.

For a particularly simple construction of the drive, the connection line of the drive can be reversibly detachably connected to the electrical connection means. The connection line is preferably attached to the electrical connection means by means of a plug connection, a clamp connection or a latching connection. The use of a plug, clamp or snap-in connection enables easy assembly.

Likewise, a supply line connecting the connecting means to the power source and/or control unit can be reversibly detachably connected or connectable to the electrical connecting means, e.g. by means of a plug connection, clamp connection or latching connection. In principle, the supply line can also be connected to the electrical connection means in a different way. For example, the supply line can be soldered or screwed to the electrical connection means.

According to an advantageous embodiment of the drive arrangement, the fastening structure can be designed in the form of a console, which comprises a first holding element and a second holding element. The holding elements serve to accommodate the drive between them. For this purpose, the holding elements are preferably spaced apart from one another in the longitudinal extent of the drive arrangement. The holding elements are preferably designed separately from one another, so that the receiving area of the fastening structure adapts to the dimensions of the drive can be adjusted. Advantageously, the printed circuit board carrying the electrical connection means can also serve to carry the support elements of the console, spaced apart from one another depending on the dimensions of the drive.

The drive connection of the connecting means can be arranged either on the first holding element or on the second holding element. In principle, however, a drive connection can also be provided on each of the holding elements. This makes it possible for the drive to be attached to the attachment structure in a first orientation or in a second orientation rotated by 180°.

Sometimes more than one drive may be required, for example due to an unfavorable lever ratio or to move narrow, elongated or heavy wings or flaps. For the electrical connection of several drives, previous drive arrangements provide for the drives to be connected to a power source and/or control unit via their respective connection lines at a central junction box. Here, too, it has proven to be problematic if the connection lines are permanently connected to the respective drives, since each drive has to be connected to the central junction box via its connection line. In alternative solutions, it is provided that the current is passed on and/or the signal is passed on to further drives within the respective drives. In this case, the lines are routed within the drive, which increases the structural complexity of the drive.

In order to avoid the disadvantages mentioned, it is provided according to an advantageous embodiment of the drive arrangement that the drive arrangement has an extension connection electrically connected to the supply connection for the electrical connection to a further drive. Just like the electrical connection means, the extension connection can be used separately from the Be trained drive. In this case, an electrical line connecting the expansion connection and the supply connection can likewise be designed separately from the drive. This results in the advantage that there is no need for a complex feedthrough for the electrical line inside the drive, as a result of which the drive has a more compact structure.

If necessary, the drive arrangement can be expanded in a modular manner via the expansion connection, with a module comprising a drive and an electrical connection means as described herein and a fastening structure as described herein.

The electrical connection means of two drives are preferably connected to one another via an extension line, in that one end of the extension line is connected to the extension connection of the connection means of one drive and the other end of the extension line is connected to the supply connection of the connection means of the other drive. Provision can also be made to electrically connect two drive arrangements to one another via an extension line in that the extension line connects the extension connection of one drive arrangement to the supply connection of the other drive arrangement.

The extension line can be connected to the extension connection and/or the supply connection in a reversibly detachable manner, e.g. by means of a plug, clamp or snap-in connection. Alternatively, the extension line can be soldered or screwed to at least one of the connections. According to a particularly simple configuration, the extension line can be designed as a cable, in particular as a ribbon cable.

According to an advantageous embodiment of the drive arrangement, the supply connection is on the first holding element and the expansion connection is on arranged on the second holding element. As a result, the drive arrangement can be expanded in one direction. However, it is also possible for an expansion connection to be provided on each of the two holding elements, so that the drive arrangement can be expanded in both directions.

The supply connection and the extension connection are preferably electrically connected to one another via a connecting line. The connecting line can be designed in the form of a cable, in particular a ribbon cable. Such a configuration is particularly advantageous for long drives. In the case of short drives, on the other hand, the connecting line can be in the form of a line integrated into a printed circuit board. This printed circuit board can also have an integrated line that electrically connects the supply connection to the drive connection.

For an assembly-friendly configuration of the drive arrangement, the drive arrangement can comprise a mounting plate which carries the fastening structure and the electrical connection means. As a result, the fastening structure and the electrical connection means can initially be preassembled on the sash or frame via the mounting plate. The drive can then be attached to the attachment structure in a simple manner.

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

The mounting plate can also form part of a housing of the drive assembly. In particular, the mounting plate can serve as a cover for the wiring of the drive arrangement.

According to an advantageous embodiment of the drive arrangement, a power pack for the drive can be arranged on the fastening structure, in particular on one of the two holding elements of the console. In this way, for example, a standardized 24 V drive can be operated with a voltage of 230 V. In addition, the power pack can also be arranged on the mounting plate.

The drive arrangements shown in the drawings are each used to move a sash, not shown, of a window or flap by means of one drive or two drives relative to a fixed window frame, also not shown. For this purpose, each of the drives has a flexible pull and push element, not shown in any more detail, which can be designed in the form of a chain or a belt.

To convert a movement of the drive into a movement of the sash, an outer end of the pull and push element is connected to a transmission means 4, which in turn is fastened to the sash when the drive arrangement is mounted on the frame or to the frame when the drive arrangement is mounted on the sash is attached.

Each of the Fig. 1a and 3a The drive assemblies illustrated comprises a drive 6 with a cover panel and two end caps 8 which, seen in the longitudinal direction of the drive assembly, each form a termination of the drive assembly at opposite ends of the drive 6. For better illustration, the drive 6 or the drives and the cover panel are shown in the detailed illustrations in Figures 1b, 1c , 2 B and 3b not reproduced.

Referring now to Figures 1a to 1c the construction of the drive arrangement according to the first embodiment will be explained in more detail.

For mechanical attachment to the casement or the window frame, the drive arrangement includes a fastening structure 10. The fastening structure 10 also serves to accommodate the drive and is designed for this purpose in the form of a console. The console 10 comprises a first holding element 12a and a second holding element 12b which is separate from the first holding element 12a. In 1c the first holding element 12a is shown schematically by dashed lines.

The holding elements 12a, 12b are each L-shaped and have two legs 14, 16 each. Specifically, each holding element 12a, 12b has a fastening leg 14 and a holding leg 16 . The attachment legs 14 are used to attach the drive assembly to the wing or frame. The holding legs 16 are spaced apart from one another in the longitudinal extent of the drive arrangement and are used to fasten the drive 6 . The end caps 8 can also be slipped onto the retaining legs 16, so that the drive arrangement has an attractive appearance in the assembled state.

In order to fasten the drive arrangement to the sash or the window frame, a pair of first bores 18 are provided in the fastening legs 14, each of which serves to receive a fastening element, such as a screw. The holding legs 16 have a pair of second bores 20 through which a fastening element, such as a screw, for connecting the drive 6 to the holding elements 12a, 12b can be inserted or screwed. Depending on the application, the holding elements 12a, 12b can also have a smaller number of bores or additional bores for fastening the drive 6 or the drive arrangement.

An electrical connection means 22 embodied separately therefrom and separately from the drive 6 is arranged on the console 10 . Like a synopsis of Figures 1a and 1b can be seen, the electrical connection means 22 is arranged on a side of the holding elements 12a, 12b, which faces away from the side which serves to accommodate the drive 6. In other words, when the drive arrangement is in the installed state, the drive 6 is on one side of the fastening structure 10 and the electrical connection means 22 is on the side of the drive 6 opposite side of the fastening structure 10 arranged. Specifically, the electrical connection means 22 is formed on a printed circuit board 24 which is attached to a side of the first holding element 12a facing away from the drive 6 .

The electrical connection means 22 has a supply connection 26 ( 1c ), to which a supply line 28 for electrically connecting the connecting means 22 to a power source and/or control unit is connected. The supply line 28 can be soldered or screwed to the supply connection 26 or attached via a plug, clamp or latch connection.

The electrical connection means 22 also has a drive connection 30 electrically connected to the supply connection 26 . In the present exemplary embodiment, the drive connection 30 and the supply connection 26 are electrically connected to one another by means of a line integrated in the printed circuit board 24 .

The drive connection 30 serves to connect the drive 6 to the electrical connection means 22 via its connection line. The connection line of the drive can be reversibly and detachably connected to the drive connection 30 of the electrical connection means 22, e.g. by means of a plug, clamp or snap-in connection. As a result, the connection line of the drive 6 can be detached from the electrical connection means 22 in a simple manner, so that the drive 6 can be easily removed.

As already mentioned, the electrical connection means 22 having the supply connection 26 and the drive connection 30 is arranged on the first holding element 12a. Next to the drive connection arranged on the first holding element 12a 30, a further drive connection 30 can also be provided on the second holding element 12b in order to enable the installation of the drive 6 in a first orientation or in a second orientation rotated by 180°.

The drive assembly also includes an extension port 32 . The expansion connection 32 is used to expand the drive arrangement with an additional drive. For this purpose, the drives 6 are connected to one another via an extension line 38, as described below in connection with FIG Figures 3a and 3b will be explained in more detail. The extension port 32 can also be used to electrically connect the drive assembly to another drive assembly. The extension line 38 connects the extension connection 32 of one drive arrangement to the supply connection 26 of the other drive arrangement.

The expansion connection 32 is provided on a circuit board 24 ′ which is separate from the circuit board 24 of the connecting means 22 . The circuit board 24' having the expansion connection 32 is arranged on a side of the console 10 facing away from the drive 6, specifically on the second holding element 12b.

The extension connection 32 is electrically connected to the supply connection 26 via a connection line 34 . In the case of the drive arrangement according to the first embodiment, the connecting line 34 is in the form of a cable 34, more precisely in the form of a ribbon cable 34. The ribbon cable 34 connects the printed circuit board 24 of the connecting means 22 to the printed circuit board 24 ′ having the expansion connection 32 . At least one end of the cable 34 can be reversibly detachably connected to one of the printed circuit boards 24, 24', for example via a plug, clamp or snap-in connection. In addition, it is possible for at least one end of the cable 34 to be firmly connected, for example soldered, to one of the printed circuit boards 24, 24'.

Regarding Figures 2a and 2b the drive arrangement according to the second embodiment will now be described, which differs from the drive arrangement according to the first embodiment in that the electrical connecting means 22 and the extension connection 32 are arranged on a common printed circuit board 24". This is the supply connection 26 and the extension connection 32 connecting connecting line 34 designed as a circuit board 24 "integrated line. The common printed circuit board 24" also carries the retaining elements 12a, 12b of the console 10, which Figure 2b are shown schematically by dashed lines.

In the Figures 3a and 3b shown third embodiment of the drive assembly is based on in the Figures 1b and 1c shown first embodiment of the drive assembly. The drive arrangement according to the third embodiment has two drives, as can be seen from the two transmission means 4 . However, the number of drives 6 is not limited to two. A drive arrangement can also have more than two drives.

A console 10 is provided for fastening the drives, as has already been explained above in connection with the first embodiment of the drive arrangement. Next to the brackets 10 there is provided for each drive 6 an electrical connection means 22 which is respectively connected to an extension connection 32 in such a way as described above in connection with the first embodiment of the drive arrangement. In principle, the electrical connection means 22 and the expansion connection 32 can also be connected to one another in the manner described in connection with the second embodiment of the drive arrangement.

How based on Figure 3b As can be seen, the drives 6 are electrically connected to one another via the extension line 38 already mentioned. An end of Extension line 38 is connected to the extension connection 32 arranged on the second holding element 12b of the first bracket 10 . The other end of the extension line 38 is connected to the supply connection 26 of the second electrical connection means 22 which is arranged on the first holding element 12a of the second bracket 10 . At least one end of the extension line 38 can be connected to one of the connections 26, 32 in a reversibly detachable manner, for example via a plug, clamp or snap-in connection. Alternatively or additionally, at least one end of the extension line 38 can be permanently connected to one of the connections 26, 32, for example soldered.

Both the consoles 10 and the electrical connection means 22 are carried by a common mounting plate 36 . The mounting plate 36 forms, together with the cover panel and the end caps 8, a housing of the drive assembly.

Finally, it should be noted that the drive arrangements described above can each have a power pack that is not shown in the drawings. The power pack is intended to adapt a mains voltage to an operating voltage of the drive 6 or the drives. The power pack is preferably arranged on the attachment structure 10 and in particular on one of the holding elements 12a, 12b of the console 10. However, the power pack can also be arranged on the mounting plate 36 . In addition, the power pack can also be arranged on a printed circuit board 24 .
