Description

Drive device for a window or a door

The invention relates to a drive device according to the preamble of claim 1.

A drive device of the generic type, which is designed for the particularly preferred application of the turn / tilt window, which is both about a vertical axis of rotation (hereinafter also a virtual or movable, eg moving axis of rotation to understand) in a rotational position and DE 103 00 654 A1 discloses the same applicant by a horizontal (upper or lower) tilting axis in a tilted position. This document shows a turn / tilt window with an electric motor drive, which has an electric motor, which acts via a gear on a shear-resistant or partially rigid drive chain - hereinafter called push chain - acts, which serves the wing from the closed position automatically to move a tilted position. The chain is designed so that it pushes the wing thrust-rigid in its tilted position during deployment and is wound up again when closing the wing or driven into a chain box. The drives are placed according to this document on the wing or milled at appropriate places in the fold of the sash.

As fittings for the Drehkippfunktion such fittings are provided in DE 103 00 654 whose axis of rotation are outside the window frame and the sash and are determined by a hinge.

The partial-pressure-stable or pressure-stable push chains act either on the Hauptausstelllenker the rotary tilt shears or from the vertical fold on the scissor hinge and thus on the pivot point directly. The push chain acts directly on a fitting in the manner of a display device between the frame and sash or on a hinge on the frame and / or wings.

In practice, the drive devices are either screwed onto the outer surfaces of the window frame or milled into the window frame, since the space required for these drives exceeds the dimensions of the window fold itself. below. The clear dimension of Fensterfalzes in today's common window systems is hardly more than 15 mm.

Here the invention goes a different way.

The invention has the features of claim 1. Advantageous embodiments are specified in the subclaims.

Thereafter, the drive housing has an elongate shape with longitudinal sides and two narrow sides at opposite ends, wherein the chain exit of the push chain directly in or immediately adjacent to one of the narrow sides of the drive housing -. in the end of the drive housing - is arranged.

It is particularly advantageous that the chain outlet is provided directly at the housing end (on one of the narrow sides of the housing) and not (as in the prior art) somewhere in the middle of the longitudinal sides, so that the chain are used optimally attacking in the outermost corner of windows can.

The motor is preferably arranged in the drive housing in the end region of the drive housing opposite the chain outlet.

According to a particularly preferred variant, the drive device for the wing is further completely installed in the window rabbet of a window, without milling on the blind or casement are required, the drive device is set in a fitting receiving groove of the casement or the frame.

The invention makes it possible to completely install the wing driving device (or other movable elements on the window or the door) in the window rabbet of a window, without the need for milling in the sash or sash. The drive device should rather be able to be set in the known fitting receiving grooves of the blind and sash.

Here, it is also particularly advantageous that the gearbox and the chain case are arranged side by side in the direction of the longitudinal extension of the drive housing. This drive device is particularly suitable - but not only - for a tilt-and-turn window with a frame and a relative to the frame tiltable about a horizontal axis of rotation and rotatable about a vertical axis pivoting wing with a sash, with a tilt and turn scissors to open and close the wing, the rotary tilt shears a hinged to the sash frame main link for tilting the wing and an attacking on the main link and on the frame, in particular hinged multi-link transmission for rotating the wing about the vertical axis of rotation. This variant forms the turn / tilt window so on that no decoupling of the drive from Drehkippbeschlag or Drehkippschere is required in the case of a rotation opening of the window, since the drive device - starting from the retracted position in the closed position of the window - the fitting during the Rotary opening of the sash securely locked on the wing in the simplest way and so fixed the main handlebar while turning quasi. Here, the use of the multi-joint transmission for securing the rotational mobility about the vertical axis proves to be surprisingly advantageous. This is made possible in particular by the fact that the push chain exits the elongated drive housing directly in the axial (or on the smallest sides).

A multi-link transmission disclosed in DE 21 13 665 C3. The above-described great advantage of Verriegeins the window by using a multi-link transmission just in combination with an electric motor drive device with a push chain - again preferably combined by arranging the push chain in the end of the main scissors to the frame (preferably at the very end or at least in the area last 20% of its length, so unlocking the chain when turning is not required) - but has not been recognized.

Further advantageous embodiments are given in the remaining dependent claims.

The invention will be described in more detail by means of embodiments with reference to the drawing with reference to embodiments. 1 shows a tilt and turn window with a rotary tilting shear and an electric motor drive; FIG. 2 shows the fitting of FIG. 1 in a viewing direction from the underside of the window; FIG. Fig. 3 is a wing frame corner, on which a drive device and a display device is arranged, which has a multi-link transmission;

4 shows a drive device by way of example on the sash frame in the upper vertical region of the sash frame spar; Fig. 5-7 three mutually perpendicular sections by a drive device.

Fig. 1 shows a tilt and turn window 1 with a frame 2 and a relative to the frame 2 pivotable about a horizontal axis of rotation X and a perpendicular thereto, vertical (here virtual) axis of rotation or tiltable wing 3 with a sash 4, in a Disk 5 is inserted.

A rotary tilt shears 6 is slidably mounted in a scissors housing 7 on the upper sash 8 and 8 pivotally supported by an additional link.

The rotary tilt shears 6 has a main scissors arm 10 for the tilted position between the frame 2 (or arranged on the frame multi-link gear) and the sash 4, which is guided on these two elements pivotally and the sash 4 in addition displaceable.

In this case, the main scissors arm 10 but not as in DE 103 00654 via a rotary fitting but by means of a multi-joint gear 11 with a plurality of mutually twistable and / or sliding further links fixed to the frame 2, which is adapted to the sash 4 relative to the frame 2 in to move a rotational position about the vertical axis of rotation (see also Fig. 2).

Corresponding to the definition of the multi-link transmission 11 in the frame 2 is at the appropriate position of the sash 4, a drive device 12 with a drive housing 13 for an electric motor not shown here and with a receiving space for the push chain 14 in the fold 15 of a - connected to the Mehrgelenkge- transmission vertical Flügelrahmenholms 16 arranged, wherein the shear-resistant push chain 14 is guided by the drive device 12 to the main scissors link 10 and thus also to the multi-link gear 11 of the rotary tilting shear 6 and the Ausstellvorrichtung.

In the figure 2, the main scissors arm 10 of the rotary tilt shears 6 is shown with the multi-link transmission 11, wherein the sash 4 relative to the frame 2 in an opening position of 90 ° - based on the closing position - is turned out.

The turn-tilt shears 11 is arranged in the upper region of the window in FIG. Fig. 2 shows according to the fitting in a viewing direction from the underside of the window forth.

The main scissors arm 10 is located on the upper horizontal sash 8 of the sash 4 with the auxiliary link 9 in an extended position.

At the end of the main scissors arm 10 towards the multi-link mechanism, a fastening lug 17 extending vertically to the plane of the main scissors arm is integrally formed on the main scissors link 10, on which the push chain 14 is fixed in the simplest manner (eg hooked) and within the window fold down into the drive housing 13 of the drive device 12 is guided.

Fig. 2 shows in particular the structure of a preferred multi-link transmission 11 for moving the wing 3 in its rotational position in and out of this out into its closed position.

The multi-link transmission has, according to FIG. 2, two transmission linkages 18, 19, which are connected to each other in a rotatable manner at a joint 20. One of the transmission link 18 is slidably guided at one of its ends with a neck pin 21 in a link 22 of the main scissors arm and guided at its opposite end with a neck pin 23 in a slot 24 of a base plate 25. The base plate 25 is in turn attached to an upper frame member 27 of the frame 2.

The second transmission link 19 is connected on the one hand via the joint 20 articulated to the first transmission link 18 and hinged on the other hand with its opposite end to the main scissors link 10 and the base plate 25 such that the wing 3 can be forced on and turned on.

From Fig. 2 it can be seen that in this multi-link transmission 11, although the two transmission link 18, 19 relative to the sash 4 and thus also the Hauptscherenlen- ker 10 their position during the opening process in rotational position to the sash 4 and thus also change to the main scissors arm 10, but that the main scissors arm 10 maintains its position to the casement 4.

In the illustrated position according to FIG. 2, the push chain 14 secures this position of the main scissors arm 10 on the sash frame 4 via the self-locking drive. This position also does not change after the sash is closed in the closed position of the multi-link transmission.

The arrangement results in a vertical movement during tilting at any point along the main scissors arm 10. This is used by the invention by arranging the push chain 14 on the fitting with Ausstellschere and multi-link gear always on the main scissors arm 10.

Particularly advantageous is the arrangement proves the fastening tab 17 at the free end of the main scissors arm 10, because there the drive device is advantageously housed in the upper vertical region of the wing, as usually in the upper horizontal region of the wing no sufficient space is available, since the actual Fitting or the display device is to be arranged.

It is also advantageous that the drive device 12 is preferably designed in terms of construction dimensions so that it is in the fold (which is a Beschichfalz itself) 15 is arranged between glare and sash without any additional to be machined recesses in the casement.

FIG. 3 again shows a wing frame corner on which the rotary tilt shears 6 are arranged, which has the multi-link mechanism 11, which in turn is fixed to a sash frame (not shown).

The chain 14 engages in a suitable manner on the opening device of a tilt-and-turn window, but it can attack in the same way on the frame or any other locations of a window to open, among other things, turn, tilt or flip window.

Here, the chain 14 can also take over additional fitting functions that otherwise - such. As in tilt or folding windows - are taken over by special fittings, such as display arms, etc .. The shear-resistant push chain 14 is again guided by the drive device 12 to the main scissors link 10 and thus also to the multi-link gear 11 of the rotary tilting shear 6 and the Ausstellvorrichtung.

At the attachment tab 17 at the free end of the main scissors arm 10, the drive device 12 is advantageously accommodated in the upper vertical region of the wing. This is particularly advantageous, since there is generally no sufficient installation space in the upper horizontal region of the wing, since the actual fitting or the opening device is to be arranged here.

In this case, the drive device 12 is preferably designed with respect to the construction dimensions that it is arranged in the fold between glare and sash without any additional to be machined recesses in the casement.

In Fig. 1, 2, 3 and 4, the drive device z. B. on the sash 3 in the upper vertical region of the sash 16.

Fig. 4 shows a section of a Fensterfalzes an aluminum window construction.

Between the frame 2 and the casement 4 is the fold 15, which is limited by the fitting receiving groove 28 on the casement. At the bottom of this groove, a cable groove 40 is arranged, in which a ribbon cable 41 is arranged (wing frame hatched drawn), which serves for power and / or control, with a plug 42 ensures the connection between the drive device 12 and the ribbon cable.

The sectional view shows how the drive device 12 is arranged in the fitting rebate 15.

Fig. 5 shows the drive device 12 in the side view, which results when the projection is perpendicular to the window plane.

The largest component that determines the installation space of the drive is the motor 29, which drives the chain wheel 30 for the chain 14. Since there is no space for motor 29 and chain 14 side by side, the motor 29 was arranged according to the invention at the opposite end of the chain outlet 38 in the drive housing.

Via a gear drive 31 or an alternative solution by means of articulated or flexible shaft or spatial oblique position of the motor so the output shaft 32 is laid in the lower part of the drive housing.

A worm drive or screw drive 33 for the reduction of the engine speed and other gear stages, e.g. with further gears 43 are driven by the output shaft 32. At the end in the region of the chain outlet from the drive housing 13, the shaft 34 is mounted for the sprocket 30.

Fig. 5 clearly shows the separation of the drive housing 13 in the lower gearbox 35 and the upper chain case 36th

The shaft 34 is guided in the chain case 36, where it is rotatably connected to the sprocket 30 and the chain 14 can drive.

6 shows a section through the plane of the lower gearbox 35.

Fig. 7 shows a section through the upper chain case 36, which has enough space to accommodate the chain 14 in the retracted state almost completely (to its end). At the end of the chain case 36 facing the motor, a circular-arc chain deflection device 37 is provided in order to optimally utilize the chain storage space of the chain case 36. A compact arrangement results from the fact that the chain is deflected only once by 180 °. The chain stowage space with respect to its longitudinal extent determines the maximum stroke of the drive. About the shaft 32, it is possible to create identical drives with identical components for different strokes.

It is particularly advantageous that the chain drive or the sprocket 30 and the motor 29 are each arranged at the remote positions or at the opposite ends of the elongated or elongated drive housing. In this way - advantageously supplemented by the longitudinal division of the drive housing in the mutually parallel subareas chain case and gear box - it is possible in a simple manner to provide a sufficient storage space for the chain on the cramped space available. The chain case 36 easily picks up the chain. The chain case 36 and the gear box 35 are preferably separated from each other by a wall 46 with openings for individual ones of the gear elements.

By suitable (e.g., the illustrated) transmissions, the drive housing 13 is divided into the lower gear box and the upper chain box.

On the drive housing (not shown here) mounting arm can be formed or arranged, which allow the drive device 12 in the fitting receiving groove 28 force and form-fitting set.

In summary, it should again be emphasized that the selected arrangement leads to a particularly space-optimized size of the drive housing 13.

Since chain outlet 38 is formed directly at the housing end (or close to it, eg, not more than 20% of the length of the drive housing from the end), the chain can be used optimally attacking in the outermost corner of windows.
