This object is achieved by the in claim 1 specified features solved.

Advantageous embodiments of the invention are in the Subclaims specified.

The drive moves the actuator. The actuator has via a coupling element, via which a coupling with egg a carrier that can be arranged on the wing is possible. Since the Control for the drive can be operated via a switching element that responds to predeterminable parameters can be a Wing of a window or door, which with an ent speaking driver is equipped with the help of the An drive be moved so that an opening for loading and Ent ventilation takes place, but also if necessary according to the predetermined parameters, a closing is made. There is a gap opening for ventilation enough, the device according to the invention can be advantageous have small dimensions.  

The switching element can, for. B. designed as a timer be a wing of a window at certain times or opens a door and after a certain time interval vall also brings it back into the closed position. One too energetic loss leading ventilation for too long a period can thereby be prevented. The ventilation of rooms can optimal times can be set. Of course you can the switching element can also be a thermostat that correspond to temperature appeals. It is also possible as a switch gate gan provide an acoustic switch that an open, ventilating window or door closes as soon as from outside Sound sources, especially at nighttime, he generated noise pollution in a predetermined limit cross within the room. After removing the noise The window or door can easily become a nuisance again be brought into the ventilation position by the drive.

The switching element can also be a rain guard, which ins especially when equipping roof windows, e.g. B. Drehfen star, with the device according to the invention is advantageous. Control of ventilation depending on one in the Indoor hygrometer is possible.

To accommodate drive and actuator with coupling element a housing is provided in which the control with the Switching element is integrated. The device according to the invention thus forms a compact component that can be fully assembled is and a simple retrofit of existing windows in buildings. There is only the pas on one wing  send carrier to attach, with which the coupling element in Active connection is to be made so that the drive drives the wing can move. The coupling element, as follows described above, the main advantage that it is also un complicated and easy ge again by the driver of the wing can be solved so that the normal window or door function is not affected.

However, it is also possible to control the controller externally to the Ge to arrange houses. For example, a smaller one Control device with one on the above Parameter-responsive sensor also at a suitable location outside the installation area of a window or door to be brought. Of course there is also an alley few external routing of a sensor possible. Such a sen sor can also be used for the actuator with actuator and coupling lungsorgan receiving housing be led out. In particular which is used for rain monitors, thermostats and acoustic switches a telecommunications or similar sensor advantageous. At a Using a timer is the external arrangement in possible within a room at a location that corresponds to appropriate setting is easily accessible.

If every window or door has one  appropriate facility is equipped, can also group operation by one or more controls respectively. The controls can also be ver different sensors are influenced. It is Z. B. also think bar, a timer with an acoustic switch kidneys.

The device according to the invention is particularly advantageous can be trained as a compact device and thus also easy to assemble by DIY enthusiasts. The assembly will still be there by much easier that the housing in a building laterally mountable housing bracket can be used. The Ge housing bracket can be fastened with appropriate fasteners, such as screws or the like, lighter on the building side be instigated as an internal drive, leadership gene for actuators and the like internals Housing, because on a housing bracket in each case optimal and Easily accessible locations provided attachment points such as screw holes or the like. In the egg conventional housing, drive elements and the like However, they are screw holes in less than optimal areas to attach, since the passages of the screws mostly through the corresponding internals in the housing are hindered.

In the housing bracket, which can be installed on the building side, the housing can be used easily. The housing with Drive, actuator and coupling element are seated after insertion zen aligned in the housing bracket provided in the intended Position when the case bracket is attached appropriately  is what is relatively simple, as described above. With advantage have housing bracket and housing mutually engaged bringable locking elements. Snap lugs are used as locking elements or similar projections and recesses particularly suitable net. These can be easily molded if the housing and the Ge housing bracket made of plastic. But also for housings and housing brackets made of metal and mixed construction are locking elements or other connecting means easy to attach.

An electric motor is preferably suitable as the drive. Elec tromotors can be operated with sufficient power produce the smallest possible dimensions and also with corre Combine the corresponding gears. The power supply of an elec tromotors and the control of its operation is with few simple construction means possible.

When using a housing bracket, the arrangement be taken such that the housing bracket and housing in the housing bracket inserted housing together in elec have trical contact contact elements. The con Clock elements can be used when using plastics for housing bracket and housing in injection molding bring in the procedure from the outset so that the homeowner ker who his window with the device according to the invention wants to equip, more difficult connection work for the instal electrical system. A power cord, that is led out of the housing bracket and corresponds chend to a power source, e.g. B. leading an outlet, ver  is the only electrical installation work which the handyman has to carry out. After inserting the housing into the building by simply screwing it on Housing bracket, the device is ready for use as soon as the contact elements are mutually engaged.

Of course, facilities are also conceivable that work with pneumatic or hydraulic drives. For example, gas pressure cylinders can be used if higher closing or opening forces are required. Also a combination with opening or closing forces strengthening springs or gas pressure cylinders is conceivable.

The actuator is particularly advantageous in the housing mounted spindle connected to the drive. Are spindles preferably suitable for linear movements via rotary drives generate and can easily with an electrical Ge drive motor are driven. By reversing the direction of rotation of the electric geared motor, according to its control, which is carried out by the control body, a movement of a Window sash are generated in the open or closed position. In addition, a spindle has the advantage that it is practical is self-locking, d. H. a window sash can also strong pressure on the actuator, e.g. B. by wind or train not to turn the spindle.

On the spindle there is a parallel to the spindle axis mobile lock nut. When the spindle rotates, the Lock nut, the movement of which can be exploited to a wing of appropriate transmission elements  Window or door to move. In the case of the invention The arrangement is such that the lock nut has a protruding projection, an end region of the Extension carries the coupling member, or as a coupling member is trained. Forces can act on the coupling element, which leads to tilting and thus to stiff movement can lead, which corresponds with higher drive power chender, negatively affects the dimensions of the device sender dimensioning increase would have to be compensated. Ver edging can, however, be done by guiding as precisely as possible during the Movement can be avoided. Precise guidance can be done with the device according to the invention z. B. achieve that an opening in the housing through which an extension to the outside protrudes as a longitudinal guide.

In another advantageous embodiment, the one enables particularly precise guidance, it is provided that as A guide rod is provided for the longitudinal guide for the extension is parallel to the spindle, with its ends in Housing are held and that the extension, preferably with by means of a sliding bush, along the guide rod is cash.

The guide rod has a round cross-section, can but also has a cross-section deviating from a circular shape sen, e.g. B. be hexagonal to an additional Verdrehsi to ensure safety.

The extension has a hole through which the Guide rod extends. Hole and guide rod are there  manufactured in such a way that they are customary for sliding fits Match each other. There is preferably one in the bore slide bushing suitable for the guide rod.

In a manner essential to the invention, one is in the housing Displacement of the extension deflected spring arranged.

When pivoting a wing, for. B. in the open position, the between swivel bearings of the Wing with which he is hinged to the frame and his Ge the entire focus of the existing lever arm on which the weight of the Wing attacks, the further the wing into the open position is tilted. The corresponding moment affects the same direction as that of the drive of the device, e.g. B. the gear motor, generated force that the wing in the Of has to tilt. The sum of the forces resulting from the Sash weight and engine power results, the spring acts due to the deflected spring. Is the feather so out? placed that a balance of forces can be established a drive motor corresponding to lower power is sufficient, which advantageously also has small dimensions, in particular, however, with very low power consumption, that is small energy consumption.

When the window sash is closed, it is removed from the Spring tension of the deflected spring can be obtained from the spring force Support the drive motor accordingly. Particularly advantageous is the use of a spring that has a progressive characteristic having. The use of a spiral compression spring enables easy attachment by placing the spring over the guide  rod is inserted, with the spring ends to one is supported on the housing and the other on the extension.

Means can be provided, e.g. B. adjustable Screw stops with which there is a spring preload allows to adapt to different wings to reach. An adjustment can also be made by exchanging a Spring against appropriate springs.

For the adjustment of the spring to be actuated it is particularly advantageous that the window on the Guide rod guided part of the extension of the on the Spindle seated lock nut can be separated. Is the Window sash with the guided on the guide rod connected from the lock nut part, can with the wing open or tilted by adjusting the Spring stop or by changing the springs Set the spring preload at a state of suspension, that is a balance between wing weight and spring force, he is enough. In this position the spring stop, the front is partially adjustable, a re-coupling to the lock nut.

A decoupling from the lock nut for adjustment The spring can also be removed by removing the guide rod. This is due to the in claims 20, 21 and 37 specified external measures possible without the Ge to open the housing of the facility. Also moving the spring to Arrangement on the left or right side of a window this is simply possible. A spring can be used to adjust the spring  plastic ring that can be coupled to the wing on the guide be pushed. After adjustment, the Removed the ring or a plastic disk and the guide rod is inserted again so that it the extension the lock nut under the deflection of the now adjusted Spring leads again.

The housing can be made of plastic. With special The advantage is a housing composed of two flat shells puts. Molded receptacles can be present in the shells be in the bearings, brackets and the like for the Spindle, the motor and especially the guide rod, as well insert the spring stop assigned to the guide rod leave so that their tight fit after assembling the Shells to the housing is guaranteed. Accordingly, in inventive way provided that bearings and brackets for the spindle, the drive and the guide rod as in the Ge interchangeably held inserts are formed.

In addition to facilitating the demon, this measure enables days and assembly for the purpose of adjusting a spring easy implementation z. B. the guide rod, which the Einrich easily move left or right to a window or a Door can be placed.

Since the coupling member with one arranged on the wing Driver must be coupled to the wing the desired To grant movement, it is provided that the driver on Wing is aligned with the plane of movement of the extension, so that mutual coupling is possible. Since the inventions  The device according to the invention also serves doors and windows To retrofit with it is to facilitate the ge mutual coupling provided that the length of the extension, or, conversely, the one engaging in the extension, e.g. B. from Wing protruding connecting part is adjustable. The Extension or the connecting part can, for. B. from two sections ten exist, one of which is fixed while the second is longitudinally displaceable relative to the fixed section, by conforming to the fixed section in one the recording is done. To set the set Sliding position can e.g. B. a clamping screw or the like be provided.

The device according to the invention must be installed also be adjustable if the desired universal Opportunity to use against any doors and windows ben should be. This is achieved by having a window opposite end of the spindle protrudes from the housing and with is provided with a handwheel. This means that the lock nut can also if necessary, by turning the spindle by hand the. Thus is a wing of a window or a door, the usual locking elements brought into the open position are adjustable by turning the spindle so that the wing the desired end positions at which he closed or is open. Can inside the case corresponding limit switches acting on the drive are arranged through which the positions reached can be determined. For this purpose, the limit switches z. B. from the outside to corresponding  Longitudinal guides can be moved and adjusted. It is ever but it is also possible to have the entire housing within the housing bracket to move and lock to the desired one To enable adjustment by which the end positions of the Moved wing of a window or a door approached can be.

An adjustment can also be achieved in that the coupling member is adjustable by a against an adjacent area of a frame part of a wing gel protruding rod is provided, the free end of a can be connected to the connector on the wing manure part.
