Description

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

The idea of automatically and automatically opening and closing windows and doors (which also include flaps) of buildings is known from the prior art ( DE 41 31 762 or DE 201 20 604 ). Both documents show a drive for a wing of a door or a ventilation flap or the like., In which a drive housing is arranged on the wing to be tilted or a frame in the upper horizontal bar. From the drive housing at least one pressure-stable drive chain is led out, which is fixed to the respective complementary element (ie the frame or the wing) and opens the wing. Closing is done by retracting the drive chain.

This drive works satisfactorily. But it consumes a lot of space. In addition, there is the not easy to solve problem in terms of construction and handling that the drive chain must be decoupled from a frame parts when a tilt-turn window is open in its rotational position and if the drive device yet to implement the tilted position (eg a ventilation position) for use should come.

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

The invention solves this object with respect to the window or the door by the subject-matter of claim 1 and with respect to the drive device by the subject-matter of claim 26.

Thereafter, the drive device - or a drive element associated with it - acts directly on a movable fitting in the manner of an opening device between the frame and sash.

Since the drive device or a drive element associated therewith, such as e.g. a chain, in particular a shear-resistant chain, acts directly on a movable fitting between the frame and sash or on the frame or sash, the problematic effect of the need to uncouple the drive chain when turning open the tilt and turn window is avoided because the fitting is designed so that it both remains attached to the wing or window frame when turning open as well as tilting.

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

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 of the drive device takes place directly in the fitting.

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

According to a particularly preferred variant, the fitting is an opening device arranged between the frame and the wing, in particular an opening shears, 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 on Ausstellvorrichtungen, especially Ausstellscheren, which u.a. also limit the opening angle of the wing relative to the frame. These display devices already provide a mechanical connection between the sash and the frame, so that the drive device only still attack between the sash and the opening device or frame and display device, but does not have to establish a direct connection between the sash and the frame. The installation at the installation ideally corresponds to that of a non-driven window.

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

In particular, the Ausstellschere a main scissor arm and an additional scissor arms, the main scissors arm is pivotally mounted with its one end on the frame and with its other end in a scissors housing and slidably on the sash. This solution is particularly suitable but not only for tilt and turn windows.

In this case, it is particularly useful when the shear-resistant drive chain or a comparable drive element acts on the main scissors arm. The power and leverage ratios are in turn particularly favorable when the thrust-resistant drive chain engages in the half of the main scissors arm facing towards the frame or the hinge on the frame, in particular to about 2/3 of the distance to the frame hinge 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 arranged on the wing, preferably as a preassembled unit. The already pre-assembled drive device thus complicates in any way the mounting of the wing on the frame at the installation, since it is already fully attached to one of the two elements, in particular on the wing or in particular forms a unit with the Ausstellschere and is mounted together with this.

The drive device may have an electromechanical drive, which operates hydraulically, pneumatically or manually operated (mechanically), wherein 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 having 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 connected with connecting elements members 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 Fig. 1 ,

Fig. 1 shows by way of example a tilt and turn window, which is provided with a drive device according to the invention for automatic operation or automatic opening and closing, in particular in a ventilation position with a tilt angle α of less than 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 those in Fig. 1 shown installation position and are not 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 would be the Fig. 1 adjust accordingly. A tilt and turn window allows opening around two alternative axes X and Y, usually around a lower axis and around an axis on either side of the right or left side (see Fig. 1 and 2 ).

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

On its side opposite the pivot axis X side, there is arranged an opening device between the wing 1 and the window frame 2, which is designed in the manner of an opening shears 3. The Ausstellschere 3 has a main scissor arm 4, whose one end is rotatably fixed to the frame 2 - here in the upper corner of the frame - and the other end is rotatably and slidably guided in a slot 13 of a bar-like scissors housing 6, which in turn is fixed to the upper side of the wing 1.

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

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

If a different ratio of the additional scissors arm 5 is selected to the main scissors arm 4, the point of application of the drive chain 17 can also be done on the additional scissors arm 5.

When opening the window and when closing the window mounted on the wing frame in the scissor housing 6 end of the main scissors arm 4 is moved while performing a rotational movement in the slot 13 of the scissors housing, since the additional scissors arm 5 pushes the main scissors arm 4 from the wing 1 away. As a result, the angle β increases between the main scissors link 4 and the frame 2, whereas when closing the window, a reverse movement takes place.

The Ausstellschere 3 ensures such a controlled movement of the wing 1 when opening and closing the tilt and turn window and in particular for a clear positioning of the wing 1 relative to the frame 2 in the closed position.

At the rod-like scissors housing 6 is - see Fig. 3 - Set and guided a push rod 8 of the jack. The 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 facing away from the fitting push rod 9, the push rod 8 provided with a plurality of recesses - which remains on the wing when the tilt window is opened - is guided up to the region of the articulation of the main scissor arm 4 on the frame 2, which is connected to a hinge-like hinge 31 on the hinge 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 scissor arm can interlock locking, which is positioned near the articulation region of the main scissors arm 4 to the frame to fix the release device on the wing for the rotational movement or to stabilize.

The interaction of the elements emerges Fig. 3 , which shows the opening device 3 in its open position, the tilting position of the tilt and turn window Fig. 1 equivalent. The main scissors link 4 has been swung out in this position on the additional scissors link 5, wherein a pin 14 in the gate 13 of the push rod 8 moved - was withdrawn here. The gate 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 here on the wing particularly compact and space-saving accommodated drive device 16. It is theoretically also conceivable to open the window with a corresponding arrangement in its rotational position and to close from this (not shown here) ,

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

The drive housing 7 can be fixed together with the scissors housing 6 by common fastening elements on the wing 1, so for example by locking, screws and / or engagement in a chamber or an open side wall of the actual sash 15 (in Fig. 3 not recognizable).

To Fig.1 and 2 passes through the drive housing 7 a wall recess of the sash 15 and is otherwise largely or completely covered by the scissors housing 6.

Advantageously, the direct engagement of the drive member of the drive device 16 to the opening device, here the Ausstellschere 3. The direct attack on the Ausstellvorrichtung causes the wing 1 including the opening device and the drive device is a self-contained unit, which is pre-assembled. On the frame 2, during the final assembly of the window or the door, only the opening device has to be fastened to the hinge or scissors strap 20. The additional arrangement and connection of fasteners of the drive device on the frame 2 is no longer required during assembly.

In addition to the arrangement on a display and the direct attack on a hinge part of the window is conceivable.

Such an embodiment shows Fig. 2 , Here, the drive chain 17 engages directly on a fitting in the form of a hinge 21 on the frame 2, which lies in the axis of rotation Y, which coincides with that of the hinge 20 for the articulation of the main scissor arm 4.

The drive housing 7 can be arranged here as in the case of the drive chain on one of the two sides of the wing 1 in or on the frame 2. It is again possible to provide a 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 is absolutely necessary for the realization of the Ausstellfunktion, which still has to be considered whether it is guided around the Umlenkzahnrad 18 or directly into the wing 1 inside. At the end of the drive chain 17, which emerges from the Umlenkzahnrad 18, a rack joins 22 (see Fig. 4 ), which meshes, for example, in or on the drive housing 7 with a drive gear 23 of the electric motor or of a downstream transmission.

As shear-resistant drive chains 17 generally require a minimum cross-sectional dimension, for which there is often not enough space in the region of the fitting rebate, a window or door, it is of particular advantage that the rack 22 a compact way is created from the attack area of Drive chain 17 on the wing 1 removes the actual electric motor drive or the drive housing 7 in the wing 1 to accommodate a place where there is enough space for the drive available. In addition, it is an advantage that the relatively expensive - since thrust stiff - drive chain 17 at least partially replaced by a lower cost push rod, in particular the rack 22 and is reduced to the minimum required to ensure the function of opening the window effective length.

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

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

FIG. 4 shows the operating principle of the deployment and drive device 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 guided past the deflection device in the form of Umlenkzahnrades 18 whose drive teeth 24 have such a distance (angular distance) from each other, the individual by connecting elements connected members 25 a, b, ... of the thrust-resistant drive chain 17 during the deflection pushed apart be that the shear stiffness repealed and a deflection of the drive chain 17 - here by 90 ° - in the direction of the frame 2 and the main scissors arm 4 even during their advancement is feasible.

Before deflecting by the Umlenkzahnrad 18, the members 25a, b, ... each in the region of complementary recesses 27 and projections 28 shear-stiffly connected to each other. This is important when opening the window, because only in this case the thrust-resistant function of the drive chain is required, because when closing the window, the drive chain is subjected to train.
