Description

The 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 a horizontal (upper or lower) tilting axis is pivotable in a tilted position, discloses the DE 103 00 654 A1 the same applicant. 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 are in the DE 103 00 654 Such fittings provided whose axis of rotation are outside of the frame and the sash and are determined by a hinge.

The Partially stable or pressure-stable thrust chains act either on the main boom of the rotary tilting shear or from the vertical Fold out on the scissor hinge and thus on the fulcrum directly one. The push chain acts directly on a fitting of the type a display device between the frame and the wing or on a hinge on the frame and / or wing.

there In practice, the drive devices are either on the Outside surfaces of the Screwed window frame or milled into the window frame, as the required space for these drives are the dimensions of the window fold itself exceeds. The light measure of Fensterfalzes common today 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 in the subclaims specified.

After that has the drive housing an elongated shape with long sides and two narrow sides at opposite ends, wherein the chain exit of the push chain directly in one or immediately adjacent to one of the narrow sides of the drive housing - i. in the end area of the drive housing - arranged is.

it Is particularly advantageous that the chain outlet directly on housing end (on one of the narrow sides of the case) and not (as in the stand the technique) is provided somewhere in the middle of the long sides, so that the Chain optimally in the extreme Corner of attacking windows can be used.

Preferably is the motor in the drive housing in the opposite to the chain exit End area of the drive housing arranged.

To A particularly preferred variant is also the drive device for the wing Completely built into the window rebate of a window, without milled on the Glare or wing frame are required, wherein the drive device in a fitting receiving groove of the sash or of the frame is fixed.

The Invention allows it, the driving device for the wing (or other movable elements at the window or door) completely in to install the window rebate of a window without milling on the Glare or wing frame be required. The drive device should rather in the Known Beschagsaufnahmenuten the blend and sash can be determined.

Here it also has a particularly advantageous that the gearbox and the chain case in the direction of the longitudinal extent of the drive housing next to each other are arranged.

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 rotary wing with a sash, with a Tilt & 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 further that even in the case of a rotation opening of the window no decoupling of the drive from Drehkippbeschlag or Drehkippschere is required, since the drive device - starting from the retracted position in the closed position of the Window - the fitting during the rotation of the window sash in the simplest way safely locked on the wing 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 discloses the DE 21 13 665 C3 , The above-described great advantage of locking 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 apparent from the remaining dependent claims.

following The invention is based on embodiments with reference to the drawing using exemplary embodiments described in more detail. It shows:

1 a tilt-and-turn window with a turn-tilt shears and an electromotive drive;

2 the fitting of the 1 in a viewing direction from the bottom of the window;

3 a wing frame corner on which a drive device and a Ausstellvorrichtung is arranged, which has a multi-link transmission;

4 a drive device exemplified on the sash in the upper vertical portion of the sash frame spar;

5 - 7 three mutually perpendicular sections through a drive device.

1 shows a tilt and turn window 1 with a frame 2 and one relative to the frame 2 about a horizontal axis of rotation X and pivotable about a perpendicular thereto, vertical (here virtual) axis of rotation rotatable or tiltable wings 3 with a sash 4 into which a disc 5 is used.

A turn-tilt shears 6 is in a scissors housing 7 on the upper wing frame spar 8th slidable and via an additional link 9 held pivotally.

The tilt and turn scissors 6 has a main scissor handlebar 10 for the tilted position between the frame 2 (or arranged on the frame multi-link gearbox) and the sash 4 on, which is pivotable on these two elements and on the sash 4 additionally slidably guided.

Here is the main scissor handlebar 10 but not like that DE 103 00654 via a rotary fitting but by means of a multi-link transmission 11 with several mutually twistable and / or sliding other arms on the frame 2 set, which is designed to the sash 4 relative to the frame 2 to move in a rotational position about the vertical axis of rotation (see also 2 ).

Corresponding to the specification of the multi-link transmission 11 in the frame 2 is at the appropriate place 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 one - connected to the multi-link gearbox vertical wing frame spar 16 arranged, with the Schubstei fe push chain 14 from the drive device 12 to the main scissor handlebar 10 and thus also to the multi-link transmission 11 the turn-tilt shears 6 or the Ausstellvorrichtung is guided.

In the 2 is the main scissor handlebar 10 the turn-tilt shears 6 with the multi-link transmission 11 shown, with the sash 4 relative to the frame 2 in an open position of 90 ° - based on the closure position - is unscrewed.

The tilt and turn scissors 11 is in the 1 arranged at the top of the window. 2 shows accordingly the fitting in a line of sight from the bottom of the window ago.

The main scissor handlebar 10 lies on the upper horizontal wing frame spar 8th of the sash 4 with the additional handlebar 9 in a stretched position.

At the end of the main scissor handlebar 10 towards the multi-link gearbox is on the main scissor link 10 a fastening tab extending vertically to the plane of the main scissor arm 17 molded, at the push chain 14 in the simplest way fixed end (eg hooked) and within the Fensterfalzes down into the drive housing 13 the drive device 12 is guided.

2 in particular also shows the construction of a preferred multi-link transmission 11 to move the grand piano 3 in his rotary position in and out of this out into its closed position.

The multi-link transmission shows 2 two transmission handlebars 18 . 19 on that at a joint 20 are rotatably connected to each other. One of the transmission handlebars 18 is at one of its ends with a neck pin 21 in a backdrop 22 slidably guided by the main scissors arm and with its opposite end with a neck pin 23 in a backdrop 24 a base plate 25 guided. The base plate 25 is in turn on an upper frame spar 27 of the frame 2 attached.

The second transmission link 19 is on the one hand about the joint 20 articulated with the first geared handlebar 18 connected and on the other hand with its opposite En de to the main scissor arm 10 and on the base plate 25 so articulated that the wing 3 forcibly opened and closed.

Out 2 can be seen that in this multi-link transmission 11 Although the two Getriebelenker 18 . 19 relative to the sash 4 and thus also to the main scissor handlebar 10 their position during the opening process in rotational position to the sash 4 and thus also to the main scissor handlebar 10 change that but the main scissorhandler 10 his position to the sash 4 maintains.

In the position shown in accordance with 2 secures the push chain 14 via the self-locking drive this position of the main scissors arm 10 on the sash frame 4 , This situation does not change after closing the wing in the closed position of the multi-joint transmission.

The arrangement results in a vertical movement during the tilting at any point along the main scissor arm 10 , This uses the invention by the push chain 14 on the fitting with cut-out scissors and multi-link gearbox always on the main scissors link 10 arranges.

Particularly advantageous is the arrangement of the fastening lug proves 17 at the free end of the main scissor handlebar 10 , because there the drive device is advantageously accommodated in the upper vertical region of the wing, since 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 here.

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

The 3 again shows a sash corner, on which the tilt and turn scissors 6 is arranged, via the multi-link transmission 11 has, which in turn is fixed to a sash, not shown.

The chain 14 engages here in a suitable manner to the Ausstellvorrichtung 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.

This can be the chain 14 also take over additional hardware 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 in turn from the drive device 12 to the main scissor handlebar 10 and thus also to the multi-link transmission 11 the turn-tilt shears 6 or the Ausstellvorrichtung out.

At the fastening strap 17 at the free end of the main scissor handlebar 10 is the drive device 12 accommodated in the upper vertical area of the wing advantageous. 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 with regard to the construction dimensions is preferably designed so that it is arranged in the fold between glare and sash without any additional to be machined recesses in the sash.

In 1 . 2 . 3 and 4 is the drive device z. B. on the sash 3 in the upper vertical area of the sash frame spar 16 arranged.

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

Between the frame 2 and the sash frame 4 is the fold 15 passing through the fitting socket groove on the sash 28 is limited. At the bottom of this groove is a cable groove 40 arranged in which a ribbon cable 41 angeord net is drawn (sash hatched), which serves for power supply and / or control, with a plug 42 the connection between the drive device 12 and the ribbon cable.

In the sectional view is shown how the drive device 12 in the fitting fold 15 is arranged.

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

The largest component that determines the installation space of the drive is the motor 29 that's the sprocket 30 for the chain 14 drives.

As for engine 29 and chain 14 There is no room next to each other, according to the invention was the engine 29 at the opposite end of the chain exit 38 arranged in the drive housing.

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

A worm drive or screw drive 33 to reduce the engine speed and other gear stages, eg with other gears 43 be from the output shaft 32 driven. At the end in the area of the chain outlet from the drive housing 13 is the wave 34 for the sprocket 30 stored.

The 5 clearly shows the separation of the drive housing 13 in the lower gearbox 35 and the upper chain case 36 ,

The wave 34 is in the chain case 36 led, where this with the sprocket 30 rotatably connected and the chain 14 can drive.

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

7 shows a section through the upper chain case 36 that has enough room to the chain 14 in the retracted state almost completely (except for their end) to be able to record. At the end of the chain box facing the engine 36 is an arcuate Kettenumlenkvorrichtung 37 provided to the chain storage compartment of the chain box 36 to use optimally. A compact arrangement results from the fact that the chain is deflected only once by 180 °. The chain storage space with respect to its longitudinal extent determines the maximum stroke of the drive. About the wave 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 engine 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 picks up the chain easily. The chain case 36 and the gearbox 35 are preferably through a wall 46 with openings for each of the transmission elements separated from each other.

By suitable (eg the illustrated) gear is the drive housing 13 divided into the lower gear box and the upper chain case.

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

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

Because chain exit 38 formed directly on the housing end (or close to, for example, 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.
