A winder in the top of the window frame pulls in a flexible chain which passes over a pulley and has an attachment to the diagonal rod.

Description

The invention relates to a window or a door, in particular for a building, with at least a wing which is pivotally mounted on a frame and with a drive device for automatically moving the wing relative to Frame as well as a drive device for such a window or such Door.

The idea of automatic or automatic opening and closing of windows and doors (which also include flaps) of buildings is well known in the art known (DE 41 31 762 or DE 201 20 604). Both writings show a drive for a wing of a door or a ventilation flap or the like, in which a drive housing on the wing to be tilted or a frame in the upper horizontal Holm is arranged. From the drive housing is at least one pressure-stable drive chain taken out, which on the respective complementary element (ie the Frame or the wing) and opens the wing. The closing takes place by retracting the drive chain.

This drive works satisfactorily. But it consumes a lot of space. About that in addition, it is not easy in terms of construction and handleability problem to be solved in that the drive chain are decoupled from a frame parts when a tilt-and-turn window is to be opened in its rotational position and when the drive device nevertheless for the realization of the tilted position (for example a ventilation position) to be used.

It is therefore the object of the invention to provide the generic window and the generic To provide door with a functionally reliable drive device in which the problem of uncoupling is avoided if the window or the door as a turn / tilt window or door is formed. The drive device should not on this Purpose be limited but in principle also for installation on folding or Tilt windows and doors are suitable. It should also be a corresponding drive device be created.

The invention solves this problem with regard to the window or the door through the The subject matter of claim 1 and with respect to the drive device by the Subject of claim 27.

Thereafter, the drive device - or a drive element associated with it acts directly on a movable fitting in the manner of a display device between Frame and sash or a hinge on the frame and / or in the thrust direction driven, rigid drive chain is guided around a Umlenkzahnrad, which has teeth on its outer circumference, which are at such a distance from each other have that the individual links of the thrust-resistant drive chain at the deflection be pushed out of the rigid connection so that the drive chain is deflectable.

Since the drive device or a drive element associated therewith, such as e.g. a Chain, in particular a shear-resistant chain, a rope or a toggle assembly directly on a movable fitting between the frame and sash or on the frame or wing acts, so the problematic effect of the need for Uncoupling the drive chain is avoided when rotating the Drehkippfensters, because the fitting is designed in such a way that it can be used both during rotary opening and during Tilt open on the wing or frame remains attached.

In other words, this means that the uncoupling problem does not occur when the fittings are already designed and / or arranged so that they without an additional manual uncoupling from the complementary element (sash or frame) work. This is generally the case for a number of fittings. Even if they are decoupled when changing from the tilted to the rotary position, it is at least no longer necessary, the drive device or its chain in addition to decouple.

Preferably, the drive device acts between the wing and the fitting or between the frame and the fitting and the introduction of force of a drive element the drive device is directly in the fitting.

That windows or the door are as a tilt-turn or tilt or folding window or door interpretable and the drive device is preferably used to open the wing in a ventilation position and for the corresponding closing of the wing from the ventilation position.

According to a particularly preferred variant, the fitting is a between frame and wing arranged Ausstellvorrichtung, in particular a Ausstellschere, which preferably acts on a hinge on the frame. This has the following Advantage. In general, it is necessary for tilting or folding wing windows anyway, to hold the wings over Ausstellvorrichtungen, in particular Ausstellscheren, which et al also limit the opening angle of the wing relative to the frame. These Ausstellvorrichtungen already make a mechanical connection between the wing and frame ago, so that the drive device only between wings and attack display device or frame and Ausstellvorrichtung, but does not have to establish a direct connection between the sash and the frame. The assembly at the installation site, this ideally corresponds to that of a non-driven window.

Preferably, the window is a tilt and turn window for which the invention is particular Way is suitable and the drive device is arranged on the wing and acts between the wing and the Ausstellschere.

In particular, the Ausstellschere has a main scissor link and an additional scissor link on, wherein the main scissor arm pivotable with its one end on Frame and pivotable with its other end in a scissors housing and slidably disposed on the sash. This solution is particularly suitable but not only for tilt and turn windows.

In this case, it is particularly useful if the shear-resistant drive chain or a comparable drive element acts on the main scissors arm. The force and Lever ratios are again particularly favorable when the shear-resistant Drive chain lying in the frame to the frame or hinge on the frame Half of the main scissors handle attacks on this, in particular to about 2/3 of Distance to the Blendrahmenschamier or band.

According to another preferred variant of the invention, the fitting is a hinge on the frame or on the wing.

According to a further particularly preferred variant, the drive device is on Wing arranged, preferably as a preassembled unit. The already pre-assembled drive device makes it difficult in any way the assembly of the wing on the frame at the installation site, as they are already completely attached to one of the two elements, in particular attached to the wing or in particular a structural unit with the Ausstellschere forms and is mounted together with this.

The drive device may comprise an electromechanical drive which is hydraulically, pneumatically or manually operated (mechanical), the electromechanical Variant is preferred.

After an independently viewable as well as advantageous development of the above variants visible solution driven in thrust direction, shear stiff drive chain is guided around a Umlenkzahnrad which has teeth on its outer circumference, which have such a distance from each other that the individual members of the thrust-resistant drive chain be deflected during the deflection of the rigid connection so that the drive chain is deflected. Before the deflection by the Umlenkzahnrad the links, preferably in the region of complementary recesses and projections are pushed together shear stiff. This is advantageous when opening the window, since in this case the shear-resistant function of the drive chain is advantageous, because when closing the window, the drive chain is subjected to train. In this case, the drive chain is preferably in the _" double direction" so viewed in the direction of thrust after _" left and right" out shear stiff, so the deflection of the chain in the thrust represents a particular problem. Nevertheless, a diversion is surprisingly easy here. For this purpose, the _" double" shear stiff drive chain is guided past the deflection in the form of Umlenkzahnrades whose teeth have such a distance (angular distance) from each other or are designed and arranged so that the individual elements connected with connecting elements of the thrust-resistant drive chain during the deflection pushed apart be that the shear stiffness repealed and a deflection of the drive chain by any angle, in particular 90 °, in the direction of the frame or the main scissor arm even when their advance is feasible.

Further advantageous embodiments are specified in the remaining subclaims.

a schematic diagram of the function of the drive device for the window of FIG. 1.

Fig. 1 shows an example of a tilt and turn window, which with a drive device according to the invention for automatic operation or for automatic opening and Close, especially in a ventilation position with a tilt angle α from here less is provided as 30 ° between the wing 1 and frame 2. The tilting opening is z. B. 170 mm, so that the tilt angle varies depending on the height of the wing.

Terms such as _" top" and _" bottom" refer to the mounting position shown in FIG. 1 below and are not intended to be limiting. The tilting window according to this type has its axis of rotation X usually _" down", a folding window, however, _" up" on. In this case, the arrangement of FIG. 1 would be adjusted accordingly. A tilt-and-turn window allows opening about two alternative axes X and Y, usually about a lower axis and about an axis on one of the right and left sides (see Figs. 1 and 2).

The wing 1 is thus at least one or according to Fig. 1 or 2 two of its sides pivotally mounted on the frame 2. The wing 1 has a sash 15 and can be provided with a disk.

At its the pivot axis X opposite side is between the wing 1 and the frame 2, a display device arranged, which in the manner of a Ausstellschere 3 is formed. The Ausstellschere 3 has a main scissors link 4, whose one end is rotatably fixed to the frame 2 - here in the upper corner the frame - and the other end rotatable and movable in a backdrop 13 a rod-like scissors housing 6 is guided, which in turn at the top Side of the wing 1 is fixed.

Between the two ends of the main scissors arm is to the main scissors arm. 4 hinged one end of an additional scissors arm 5, the other end in turn rotatable - but immovable - is articulated on the scissor housing 6. The cone-like The axis of rotation 12 of the additional scissors arm 5 on the wing 1 passes through the scissors housing. 6

In Fig. 1, the one end of the auxiliary scissors arm 5 is approximately at one point of the main scissor arm 4 fixed, which here exemplary - but from the leverage ratios ago favorable - to about 1/3 of the length of the main scissors link between the wing 1 and the frame 2 is located.

If another ratio of the additional scissors arm 5 to the main scissors arm. 4 chosen, the point of application of the drive chain 17 and the additional scissors link. 5 respectively.

When you open the window and when closing the window that is on the sash in the scissors housing 6 mounted end of the main scissors arm 4 under implementation a rotational movement in the slot 13 of the scissors housing displaced because of Additional scissors link 5 the main scissors link 4 from the wing 1 pushes away. Thereby the angle β between the main scissors arm 4 and the frame increases 2, whereas when closing the window a reverse movement takes place.

The Ausstellschere 3 ensures such a controlled movement of the wing 1 at Opening and closing the turn-tilt window and in particular for a unique Positioning of the wing 1 relative to the frame 2 in the closed position.

On rod-like scissors housing 6 - see Fig. 3 - a push rod 8 of the jack set and guided. One end of the push rod 8 is with a Fitting push rod 9 of an otherwise not shown here locking fitting connected. At its end remote from the fitting push rod 9 end is with a plurality of recesses provided push rod 8 - the opening of the tilting window remains on the wing - until the area of the articulation of the main scissors arm 4 am Blend 2 out, the on a hinge-like or hinge-like hinge 31 am Frame 2 is hinged. The push rod 8 includes the frame-like scissors housing 6 and extends to a latch 10, in which a locking bolt 11 of the Main scissors can interlock interlocking, which close to the articulation of the Main scissors arm 4 is positioned to the frame to the release device to fix on the wing for the rotational movement or to stabilize.

The interaction of the elements results from Fig. 3, which shows the Ausstellvorrichtung 3 in its open position, the tilting position of the tilt and turn window off Fig. 1 corresponds. The main scissors link 4 is in this position on the additional scissors arm 5 has been swung out, with a pin 14 in the gate 13 of the Push rod 8 shifted - here was withdrawn. The backdrop 13 limits the Movement of the main scissors arm 4 and thus the opening angle of the tilt and turn window.

To open and close the window 1 in the tilted position serves here on the wing particularly compact and space-saving accommodated drive device 16. It is theoretical also conceivable, the window with a corresponding arrangement in its rotational position to open and close from this (not shown here).

The drive device 16 has to open and close the window as a drive member a rigid drive chain 17, here in the middle or near the middle of the main scissors arm 4 is fixed to this (pivot point 26) and from the Main scissors link 4 from approximately parallel to the opening direction of the window vertically extends to the sash 15 and there by 90 ° to a deflection in the form a Umlenkzahnrads 18 is guided to a drive housing 7, which for receiving a here not to be recognized electric motor, possibly together with gearbox serves. Of the Linkage point 26 can also be arranged on the additional scissors link 5.

The drive housing 7, together with the scissor housing 6 by common Fixing elements are fixed to the wing 1, so for example by locking, Screws and / or an engagement in a chamber or an open side wall the actual sash 15 (not visible in FIG. 3).

According to Fig. And 2, the drive housing 7 passes through a wall recess of the sash 15 and is otherwise largely or completely covered by the scissor housing 6.

The direct attack of the drive member of the drive device 16 is advantageous the Ausstellvorrichtung, here the Ausstellschere 3. The direct attack on the Ausstellvorrichtung causes the wing 1 including the jack and the drive device is a self-contained unit, which preassembled is. At the frame 2 must be during final assembly of the window or door only nor the opening device are attached to the hinge or scissor belt 20. The additional arrangement and connection of fasteners of the drive device on the frame 2 is no longer required during installation.

In addition to the arrangement on a Ausstellvorrichtung is also the direct attack on a Hinge part of the window conceivable.

Such an embodiment is shown in FIG. 2. Here, the drive chain 17 engages directly a fitting in the form of a hinge 21 on the frame 2, in the axis of rotation Y lies with that of the hinge 20 for hinging the main scissor arm. 4 matches.

The drive housing 7 can here as in the drive chain on one side the wing 1 may be arranged in or on the frame 2. It is possible, in turn Provide Umlenkzahnrad 18.

Fig. 3 shows the display device together with drive device 16 in a separate representation.

The drive chain 17 has only the length which for the realization of the Ausstellfunktion is essential, while still taking into account whether they are around the Umlenkzahnrad 18 is guided or directly into the wing 1 inside. At the end of the drive chain 17, which emerges from the Umlenkzahnrad 18, a rack 22 connects (see Fig. 4), which, for example, in or on the drive housing 7 with a drive gear 23 of the electric motor or a downstream transmission combs.

As shear-resistant drive chains 17 generally require a minimum cross-sectional dimension, for which in the area of the fitting fold a window or a door often not enough Space is available, it is of particular advantage that with the rack 22nd a compact way is created from the attack area of the drive chain 17 on the wing 1 removes the actual electric motor drive or the drive housing 7 in the wing 1 in a place to accommodate enough for the drive Space is available. In addition, it is an advantage that the relatively expensive - As shear stiff - drive chain 17 at least partially by a cheaper Push rod, especially the rack 22, replaced and to the minimum to ensure the function of opening the window necessary Wirklength is reduced.

Preferably, the push rod 22 is positively connected to the shear-resistant drive chain 17 connected, so that the flexible drive chain 17 at a greater distance or in a can be arranged almost any distance to the drive.

To drive the push rod 22 a variety of mechanisms are conceivable, such a drive by the drive gear 23 or a spindle or any other stroke-generating motor or manual drive mechanism (latter variants not shown here).

Figure 4 shows the operating principle of the raising and driving device of FIG. 1 in an enlarged and simplified representation.

It should also be emphasized that the drive chain 17 here in the _" double direction" so viewed in the direction of thrust to the left and right is shear stiff, so that therefore the deflection of the chain in the thrust direction is a particular problem. Nevertheless, a diversion is possible. This will be explained in more detail below.

The shear-resistant drive chain 17 is on the deflection device in the form of Umlenkzahnrades 18 passed, the drive teeth 24 such a distance (angular distance) have each other, the individual connected by fasteners Links 25a, b, ... of the thrust-resistant drive chain 17 during the deflection so pressed apart be repealed that the shear stiffness and a deflection of the Drive chain 17 - here by 90 ° - in the direction of the frame 2 or the main scissors arm 4 is also feasible in their advancement.

Before being deflected by the Umlenkzahnrad 18, the members 25 a, b, ... in each case Area of complementary recesses 27 and protrusions 28 shear stiff with each other connected. This is important when opening the window, because only here the shear-resistant Function of the drive chain is required, because when closing the window is the Drive chain stressed to train.
