Description

The invention relates to a building opening-closing element that can be rotated, tilted and/or slid, such as a window, a door and/or a facade element.

Windows, doors and/or facade elements are known from the prior art, the sliding and/or casement element of which can be moved by means of a motor drive in order to open or close it automatically.

For example, the reference discloses EP 1 836 367 B1 a turn/tilt window with a window frame and a leaf with a casement frame that can be tilted about a horizontal axis of rotation and rotated about a vertical axis of rotation relative to the window frame. The turn/tilt window also has an electromotive drive device for opening the wing into its tilted position and for closing the wing from the tilted position.

The pamphlet EP 1 700 284 B1 discloses a window in which a handle for adjusting the sash into different operating positions is connected via electrical lines or a radio link to an electromechanical drive device for opening and closing the sash into and out of a tilted position in order to detect and monitor locking of the window .

The object of the present invention is to create an automatically rotating, tilting and/or sliding building opening/closing element, such as a window, a door and/or a facade element, which conveniently enables soundproof, high-quality ventilation.

The invention achieves this object by the subject matter of independent claims 1 and 22. Advantageous embodiments can be taken from the dependent claims.

According to claim 1, a building opening-closing element is provided. A building opening-closing element is, for example, a window, an opening element of a facade element or a door. The building opening/closing element has at least the following features:

• a blind frame composed of several frame profiles, a sash and/or sliding frame composed of several frame profiles, which is movable relative to the blind frame, wherein a circumferential frame rebate space is formed at least partially between the frame profiles of the blind frame and the frame profiles of the sash and/or sliding frame , at least one ventilation duct formed in at least one of the frame profiles of the blind frame or in at least one of the frame profiles of the casement and/or sash frame, which has a first ventilation duct opening and a second ventilation duct opening, the casement and/or sash frame and the blind frame being designed for this purpose , to close at least one of the ventilation duct openings in the closed position, and to release both ventilation duct openings of the at least one ventilation duct in the ventilation position, an electromotive drive device for the reversible adjustment of the wing and/or sliding frame from the closed position to the ventilation position and a control device provided in or on the building opening-closing element and/or a control provided externally for this purpose, which is set up to control the electromotive drive device depending on the position of the casement and/or sliding frame.

The building opening/closing element is characterized in that the control device and/or the external control is also set up to control the electromotive drive device as a function of one or more detected environmental conditions.

For this purpose, the control device on the respective element can also be correspondingly controlled or can be controlled by a higher-level controller and/or an operating element outside of the element. The control device in the respective element can then also be limited to a “minimum” and, for example, only be designed to control the motor depending on control commands that are received or received from the higher-level controller, for example to move or move a motor turn the wing on and off.

The detection of the ambient conditions and the activation of the electromotive drive device of the building opening/closing element as a function of these enables a reaction, in particular a quick reaction, to changes in the ambient conditions. Since the closed position differs from the ventilation position in that in the ventilation position both ventilation duct openings are open, so that the building opening-closing element allows ventilation of the interior of the building, while in the closed position at least one of the two ventilation duct openings is closed, and the building opening-closing element therefore does not Permits ventilation, allows the building to open The ventilation closing element enables an automatic changeover, which is very convenient for the operator, between ventilation and no ventilation of the interior of the building. Since the operator himself does not necessarily have to intervene, or not at all, such a change is also possible in his absence.

According to one variant, it is expedient if the building opening/closing element directly has an environmental sensor for detecting environmental conditions. This is then connected to the control device - either directly or possibly also via a higher-level control - e.g. a main control of a residential unit or the building - so that the environmental condition(s) can be recorded.

For this purpose it can be provided that the environment sensor is arranged on the window frame or the casement. It can be arranged, for example, in the frame rebate space on the window frame or the sash or the sash, for example, be arranged covered in the closed state. However, it can also be arranged on the outside of the window frame when installed in a building opening, where environmental conditions such as outside temperature and/or a current sound level and/or other conditions such as wind or rain or the like can be detected particularly well.

Alternatively or optionally, it can also be provided that the control device is directly or indirectly connected to an environmental sensor arranged externally outside the building opening/closing element. In this way, the environmental conditions can be recorded elsewhere and still be used to control the "soundproof ventilation window". The environmental sensor can also initially collect data at another location, for example as a sensor of a weather station or another measuring station, and then this data can be used directly or e.g. via previous processing and retrieval, e.g. via an Internet connection or the like Control device can be supplied.

For this purpose or for other reasons, it can be provided that the control device is directly or indirectly connected to a higher-level control system or a main control system arranged externally outside the building opening/closing element. This can have a main control computer, in particular a server, which can also control a number of opening/closing elements or other devices in at least one building or at least one residential unit. The server can then in turn also be capable of making inputs itself and can accept input commands from an input device such as a mobile phone with an app or the like or be controllable itself.

A control routine can be provided in the control software on this server or in the control device on the opening-closing element, which controls the respective opening-closing element and opens or closes it as desired, for example depending on environmental conditions that occur at another neighboring location or be detected on another opening-closing element with an environmental sensor or in some other way.

According to such a variant, it is not necessary, for example, to provide environmental sensors on all opening/closing elements of a building.

Rather, it may be sufficient to provide one or more of the environmental sensors at just a single opening/closing element or at another location in the respective building and to record their measured values in order to then, depending on at least these measured values - e.g. depending on the ambient temperature or the Interior temperature - to control the opening-closing elements.

Limit values at which the opening/closing element is switched over or moved from one position to another can be specified by the user or be pre-stored in a data memory of the control device or at another location.

1. a) des Schallpegels innenraumseitig und/oder außenraumseitig; und/oder
2. b) einer die Lüftungskassette durchströmenden Luftmenge; und/oder
3. c) eines Feinstaubanteils innerhalb der Lüftungskassette; und/oder
4. d) der Beschaffenheit der die Lüftungskassette durchströmenden Luft, insbesondere ihren Kohlendioxidanteil, Feinstaubanteil, Schadstoffanteil, enthaltene Allergene, Luftfeuchtigkeit und/oder Lufttemperatur und/oder weitere Parameter; und/oder
5. e) auf die Lüftungskassette einwirkenden Erschütterungen; und/oder
6. f) Wetterbedingungen, insbesondere Temperatur innenraumseitig und/oder außenraumseitig, Regen und/oder Wind.

For this purpose, the higher-level control system or the control device that may be provided is set up to control the electromotive drive device as a function of one or more environmental conditions. The environment sensor can be provided for detecting:

1. a) the sound level inside and/or outside; and or
2. b) a quantity of air flowing through the ventilation cassette; and or
3. c) a proportion of fine dust within the ventilation cassette; and or
4. d) the quality of the air flowing through the ventilation cassette, in particular its carbon dioxide content, fine dust content, pollutant content, allergens contained, humidity and/or air temperature and/or other parameters; and or
5. e) vibrations acting on the ventilation cassette; and or
6. f) Weather conditions, in particular temperature inside and/or outside, rain and/or wind.

According to an optional development, it can also be provided that a sensor, in particular a frame sensor, is also provided for detecting the position of the casement and/or sash frame, the signal from which the control device can also process.

Provision can also preferably be made for the one or more ventilation ducts to be formed in at least one ventilation cassette or several ventilation cassettes, which is/are inserted in the window frame or the sash and/or sash frame or in the respective window frame profile or the respective sash frame profile /are. The formation of the ventilation ducts in at least one ventilation cassette significantly simplifies the formation of the ventilation duct because it does not have to be formed directly in the hollow chamber profiles in a complicated manner. Rather, it is sufficient to provide or form a recess there and then insert the pre-assembled ventilation cassette into the recess, e.g. latching or clamping. This makes it easy and simple to form a ventilation duct in a ventilation opening-closing element.

The ventilation cassette preferably has an insert or a plurality of inserts arranged next to one another and/or one behind the other. In this context, it is preferred that the insert or inserts comprise sound-reducing means and/or filter means. For example, one or more deflections and/or subdivisions of the air flow and/or an acoustic absorber element arrangement can be provided as sound reduction means. Furthermore, an active sound element can also be provided as a sound reduction means. Filter means are preferably, for example, an exhaust gas filter, carbon dioxide filter, fine dust filter and/or ozone filter. By using several inserts with different noise reduction means and/or filter means, the building opening/closing element can be adapted to the ambient conditions, for example to an urban environment by using different pollutant filters, fine dust filters and/or noise reduction means.

In this case, the environment sensor can be arranged in the or one of the ventilation cassettes, where it is advantageously and easily accommodated. In principle, however, a different positioning of the environment sensor is also possible, for example on or in the window frame or on or in the casement and/or sliding frame, as explained in more detail above by way of example.

In order to be able to react to a large number of environmental conditions, a number of environmental sensors can also be provided.

The control device is preferably set up to activate the electromotive drive device when a measured value of the ambient conditions detected or an ambient value calculated from the measured value of the ambient conditions detected reaches, exceeds or falls below a preset value, e.g. adjustable by the user, in particular a limit value. The sash and/or sliding frame is preferably adjusted from the closed position to the ventilation position or vice versa. However, the control device can also be provided and designed accordingly by a higher-level main control, for example a building server for controlling this and possibly other further control devices on further building opening/closing elements or the like on one or more buildings.

Increased comfort is achieved in that the casement and/or sash frame can also be adjusted into at least one further intermediate ventilation position, which is arranged between the closed position and the ventilation position. It is preferred that the building opening-closing element is closed in the closed position, partially open in the intermediate ventilation position, and open in the ventilation position. When sound reduction means are arranged in the ventilation cassette or cassettes, high sound insulation can be achieved in the closed position and low sound insulation can still be achieved in the intermediate ventilation position. Furthermore, no sound insulation can take place in the ventilation position, but a high level of air exchange can be achieved.

It is preferred that the adjustment of the casement and/or sliding frame takes place directly from the closed position into the ventilation intermediate position or ventilation position, or back again. However, another adjustment may also be possible, in which the casement and/or sash frame, depending on its current position, is not adjusted to the next position but directly to a subsequent position, for example starting from the closed position directly to the ventilation position without to remain in the intermediate ventilation position.

In order to adjust the control device, it is preferred that it includes an input and/or output interface for inputting and/or outputting, and/or a data memory for storing operationally relevant data. Such operational Relevant data can be, for example, the environmental conditions to be recorded, the measured values recorded, the calculated environmental values, data from external information sources and/or limit values. Such operationally relevant data is preferably stored in the data memory so that it can be called up at any time. With the help of the stored data, the control device can be set up to be self-learning, so that, for example, after frequent intervention by the operator when a noise level is exceeded, the control device automatically activates the electromagnetic drive device.

The use of external information sources and/or limit values makes it possible, for example, to set the control device on the basis of predictions, for example with regard to noise development, pollution, weather changes and/or air quality. Measuring stations, in particular weather stations, or internet-based data can be used as external sources of information.

Furthermore, periods of time in which ventilation is explicitly intended or is not intended to be provided can be configurable. With such time periods, venting or closing of the building opening-closing element can be achieved without the operator being present.

The input and/or output interface can be designed for wired or wireless communication with an operator unit. Conventional transmission technologies such as serial, parallel, LAN, USB or other technologies can be used for wired communication. Wireless communication is possible, for example, via mobile communications, WLAN, Lora Wan, NB-IOT, IRdA, Bluetooth or others.

The operator unit can be arranged on the building opening-closing element, in particular integrated into the building opening-closing element.

However, it is preferred that the operator unit is a device independent of the building opening/closing element. As such, it is preferably located remotely from the building opening-closing element. It can have an independent control unit and/or user interface. In a preferred embodiment, the operator unit is a personal computer, a tablet PC, a notebook, an application-specific terminal or a smartphone. The operator unit is particularly preferably set up to input control commands for the control device. As a result, the electromotive drive device can be controlled directly by the operator unit.

According to a further advantageous variant of the invention, it can be provided that the electromotive drive device for reversibly adjusting the casement and/or sash frame from the closed position to the ventilation position is housed in the frame rebate space in a completely or partially concealed manner, which is particularly advantageous from a visual point of view. In addition, it is well protected there when closed.

According to the invention, according to a further variant, a system with several or a large number of building opening-closing elements according to the invention can also be implemented, which has a main control with a control computer for several of these building opening-closing elements, the main control being designed to control the individual control devices of the individual building Control opening-closing elements depending on the environmental conditions and/or control inputs. The superordinate main control and the control devices can then be connected to one another by wire or wirelessly, for example via radio or another wireless connection.

The object is also achieved with a method for controlling a position of a casement and/or sliding frame relative to a window frame of a building opening-closing element according to one or more of the preceding claims, in which at least one environmental sensor arranged on the building opening-closing element or externally thereto has one or several environmental conditions are detected and a control device on the building opening/closing element - or a control, in particular a main control, external thereto - adjusts the sash and/or sash depending on its current position relative to the window frame if the recorded measured value or a measured value based on the recorded value calculated environmental value reaches, exceeds or falls below a preset limit value.

The process enables a quick response to spontaneously changing environmental conditions. As a result, the building opening-closing element can be automatically and quickly partially opened, opened, partially closed or closed in response to the changed environmental conditions.

The limit value, based on which the adjustment of the casement and/or sash frame takes place relative to the window frame, is preferably preset, or based on an operator input and/or adjusted or calculated based on an external source of information. In addition, an adaptive algorithm can be provided, which detects a limit value, for example, based on manual intervention by the operator.

Various exemplary embodiments are described in the following description of the figures.

However, they can also be combined with other exemplary embodiments, shown or not shown, and are also suitable in each case as advantageous configurations of the objects described in one or more of the main and subclaims.

1 shows a section of a building opening-closing element, which is designed here as a window. However, the invention is not limited to building opening/closing elements designed as windows, but also includes doors and facade elements.

The window has a peripheral frame 1 . This is composed of several window frame profiles 1' to form a frame shape, in particular a rectangular shape.

On the frame 1 relative to the frame 1 movable wing is arranged. The wing preferably has a peripherally closed wing frame 2 and a surface element 3 inserted into the wing frame 2 and accommodated by it, such as a disc. The wing frame 2 is composed of several wing frame profiles 2' to form a frame shape, in particular a rectangular shape.

The frame profiles 1' and/or the casement profiles 2' can be designed as multi-chamber hollow profiles.

The window frame profiles can be designed as plastic profiles. However, they can also be designed as so-called composite profiles. Then they usually consist of one or more metal profiles - here also synonymously called metal shells - and one or more insulating bars. A design is preferred in which two metal profile levels are connected to one another via an insulating strip level, which is generally made of plastic. However, other, further designs are also conceivable, in particular designs with a metal profile level and an insulating profile level made of plastic, as well as designs with three metal profile levels and two insulating profile levels.

In the respective exemplary embodiments, a preferably circumferential frame rebate space F is formed between the outer frame 1 and the sash frame 2 or their frame profiles 1′, 2′. This frame rebate space F essentially extends between the outer circumference of the sash frame 2 and the inner circumference of the window frame 1.

The window is used to be able to close and open a room opening in a building (not shown here), with room I (e.g. a room surrounding a building) being separated from room II (e.g. an interior of the building).

In the following, the terms “frame profile 1′” and “frame 1” as well as “sash frame profile 2′” and “sash frame 2” are also used interchangeably in this respect. Because the means and configurations discussed below can each preferably be formed circumferentially or in sections on the window frame 1 or on the casement 2 . They can only be formed on one of the corresponding frame profiles of the casement 2 and the window frame 1 (e.g. on the frame profiles opposite a joint axis) or on several of the corresponding frame profiles of the casement 2 and the window frame 1. At the perpendicular to the 1b Corresponding gaps also form on the sides of the window frame running in the ventilation position, but they do not have a constant width when the window is pivoted open. Nevertheless, in addition to improving the ventilation effect can also be used these pages each ventilation ducts 8 in the manner of 1a and 1b also be trained.

The casement 2 can - preferably on one side or towards an adjacent room II - have a contact bar 4 with which it rests in the closed position on the window frame 1 directly or via a stop seal 5 attached to the casement 2 . Similarly, the window frame 1 can have a contact web 6, preferably on the other side or towards the other adjacent room I, in which it rests in the closed position on the window frame 1 directly or via a stop seal 7 attached to the contact web 6. In this way, a gap SII and a gap SI between the frame rebate space F and the space I or II are tightly sealed.

It is provided that at least in the window frame 1 or in the casement 2 - here in the window frame 1 - a ventilation duct 8 (dashed line) is formed, which has a first ventilation duct opening 9 and a second ventilation duct opening 10 . Provision is preferably made for ventilation duct openings 9 and 10 to open into frame rebate space F. The ventilation duct 8 can have a U-shape.

To 1 it is further provided that at least the one or more hollow profiles of the window frame 1 or the casement 2, in which the ventilation duct 8 is formed, are designed as multi-chamber hollow profiles made of plastic.

These multi-chamber hollow profiles made of plastic preferably have three or more hollow chambers H1, H2, . . . between room side I and room II. According to the embodiment of 1 seven hollow chambers H1 to H7 are provided between room I and room II (“from inside to outside”). Further hollow chambers can also be formed perpendicularly to the direction I-II, in particular in the area of the contact webs. Each of these measures and in combination ensure very good thermal insulation properties. The intermediate walls between the hollow chambers inside the profiles are preferably thinner than the outer walls, in particular towards room I and towards room II.

One or more further hollow chambers H8, H9, H10, H11 can also be provided. One or more of these further hollow chambers H8, H9 can advantageously be provided in the respective contact web 4 or 6. These measures improve the soundproofing and thermal insulation, either individually or together.

It can advantageously be provided that all the hollow profiles of the window frame 1 or the casement 2 are designed as multi-chamber hollow profiles made of plastic.

A wide variety of plastics, among others, are suitable as the material. The plastic is particularly preferably a PVC. Provision can also be made for one or more of the multi-chamber hollow profiles made of plastic of the frame 1 and/or one or more of the multi-chamber hollow profiles made of plastic of the casement 2 to have at least one reinforcing reinforcement 11, 12.

The respective reinforcing reinforcement 11, 12 can consist of a different material than the multi-chamber hollow profile made of plastic, for example a metal, in particular steel, and can be designed as a metal profile, for example a metal strip or metal plate or the like. However, it can also be designed as a reinforcing reinforcement made of a different plastic, for example a glass fiber reinforced plastic.

The multi-chamber profiles then preferably have a continuous plastic outer wall on a first side I of the room and preferably have a continuous plastic outer wall on a second side II of the room.

It is further preferred that the ventilation duct 8 is formed in a recess 13, in particular in a milled-out section, which is formed in the window frame 1 or the casement frame 2, starting from the frame rebate space.

It can further advantageously be provided that the ventilation duct 8 is formed in a ventilation cassette 14, which is inserted into the recess 13, in particular into the cutout, in the frame 1 or the casement 2. It is also possible for several of these ventilation cassettes 14 to be provided per frame profile or on several sides of the frame (not shown). The ventilation duct 8 can be formed in just one or in several of the profiles of the surrounding window frame 1 or the casement 2 in a simple manner.

Provision can preferably be made for the respective ventilation cassette 14 to have a channel or trough-like base element 15 . Provision can also be made for the respective ventilation cassette 14 to have a cover 16 .

The cover 16 is preferably aligned with the frame rebate space F.

A center seal 18 which extends into the frame rebate space F is preferably formed on the window frame profile. The center seal 18 can be attached to the ventilation cassette 14, in particular to the cover 16. Provision can be made for a fastening means, in particular an undercut groove 17, for the central seal 18 to be formed on the ventilation cassette 14, in particular on the cover 16.

The center seal 18 may include a seal base 20 with a seal foot 21 inserted into the groove. The seal 18 may further include a seal portion 22 pivotally attached to the seal base 20 . This can be designed as a single sealing lip ( 1a and 1b) or as a combination of two or more sealing lips. The sealing section 22 can in particular have a sealing lip that is curved in itself and/or has another joint section, so that it is divided into two lip areas that are movable relative to one another and connect to form a longer lip.

It is particularly advantageous if the sealing section 22 can be pivoted relative to the sealing base 21 and if it is so long that it can be in contact with the casement 2 . There he is preferably on with an end section. This end section can be arcuate.

The sealing section 22 can have a contact sliding section 23 as an end section, which can rest on the corresponding frame profile, here the casement profile, during relative movements between the frame 1 and the casement 2 and can slide well. This results in a harmonious, easy opening movement that is not significantly impeded by the adjacent sealing surface.

The contact sliding section 23 is preferably provided on the center seal where a ventilation channel 8 is also provided in the respective frame profile. This can be on one side of the window frame 1 or sash 2 or on several sides, preferably on three sides. If it is a tilting window, no ventilation duct is preferably formed on the side on which the tilting axis lies. Here, the abutment slide portion 23 can be omitted.

It is particularly advantageous that the sealing section 22 is preferably so long that when the sash is opened it initially remains in contact with the sash frame 2 over a certain opening angle or at least is or comes into contact with the sash frame 2 in a ventilation position to be explained , so that it divides the frame rebate space F into two areas in the ventilation position, between which air is exchanged essentially only via the ventilation duct 8 .

The center seal 18 thus divides the rebate space F into a first and a second region FI, FII (corresponding to the orientation to spaces I and II), between which an exchange of air is only possible via the ventilation duct 8 formed in the window frame 1.

Alternatively, when the ventilation duct 8 is arranged in the window frame 1 , the center seal can be attached to the casement frame 2 and extends to the window frame 1 . Even then, the sealing section 22 should preferably be so long that when the sash is opened, it initially remains in contact with the window frame 1 over a certain opening angle or at least is or comes into contact with the window frame 1 in a ventilation position that is yet to be explained, so that it divides the frame rebate space F into two areas in the ventilation position, between which air is exchanged essentially only via the ventilation duct 8 .

It should be noted again at this point that the arrangement can also be “completely” reversed, in which case the ventilation duct is located in the casement frame 2 . The center seal 18 can then be arranged from the casement frame 2 to the frame 1 or vice versa.

In the ventilation position L of 1b the wing was moved relative to the frame 1 in an open position, in particular pivoted and / or moved. This open position is a ventilation position. You can - but this is not mandatory - the maximum achievable position when tilting or rotating or the like. Correspond.

The gaps SI and SII are open in this position, since the stop seals 5 and 7 are no longer in contact with the frame 1 or sash 2. The center seal 18 is still in contact with the sash frame 2. The sash is still partially within the scope defined by the frame 2. Since the central seal 18 blocks the direct transition between the spaces FI and FII, an exchange of air between these spaces FI and FII and thus also an exchange of air between spaces I and II can only take place through the ventilation duct. This provides a very advantageous combination of a ventilation and a soundproofing effect.

If the room I is, for example, the surrounding area of a building and the room II is an interior II of the building, air can flow through the gap SI, the frame rebate section FI, the Ventilation duct 8, the frame rebate section FII and the gap SII flow into the interior I. The sound is advantageously dampened in particular by deflecting the direction of the ventilation duct.

The air flowing through should therefore preferably have to change direction once or several times within the ventilation duct. This has a beneficial effect on sound insulation.

The ventilation duct 8 has the first ventilation duct opening 9 and the second ventilation duct opening 10. These two ventilation duct openings 9, 10 can be formed in the ventilation cassette 14. The two ventilation duct openings 9, 10 are preferably formed in the cover 16.

Provision can also advantageously be made for one or particularly preferably both ventilation duct openings 9, 10 to be aligned towards the frame rebate space F.

At least one wall 19 can be formed within the ventilation cassette 14, which divides the interior of the ventilation cassette into sections. This wall 19 can have at least one passage 19a. One of the ventilation duct openings 9, 10 is then located in one of the sections.

In a preferred embodiment, the ventilation duct 8 runs within the ventilation cassette 14 (or also without a ventilation cassette) in an approximately U-shape. It extends from the first ventilation duct opening 9 approximately parallel to the surface element 3 into the ventilation cassette 14, then runs approximately perpendicular to the surface element 3, extends there through the passage 19a of the wall 19 and again runs approximately parallel to the surface element up to the ventilation duct opening 10 the direction of the air flowing through changes several times. This insulates or prevents the passage of sound from room I to room II and vice versa. Nevertheless, an air flow for ventilation can pass from room I to room II.

The frame profiles, in particular the outer walls of rooms I and II are according to the embodiment of 1 formed from a plastics material, preferably PVC. Preferably, they are made entirely of plastic - possibly except for inner reinforcement profiles or reinforcement reinforcements. You can be made in one piece, especially if they are made of plastic.

The outer walls of the plastic hollow chamber profiles preferably have a thickness of 2-4 mm, while the thickness of the partition walls forming hollow chambers H1-H7 can be 1-2 mm.

In a preferred embodiment, additional metal reinforcements 10, 11 are optionally arranged in the hollow chambers for static reinforcement and further subdivide them.

The frame profiles 1′, 2′ used are particularly preferably those with embedded reinforcement profiles that are produced by a coextrusion process, the reinforcement reinforcements being made of aluminum or fiber-reinforced plastic.

It is preferably provided that the stop seals (inside/outside) 5, 7 and the middle seal 18 are formed circumferentially, ie run on four sides of the frame, while the sealing section is not provided on all sides of the frame.

In the construction according to the invention, the contact sliding section 23 closes the frame rebate space or gap between the blind frame and the sash frame up to the outer profile edge of the sash frame 2 . As a result, a larger opening width ("W") is achieved compared to the prior art. Depending on the profile width (“B” between room I and room II), 50 to 80 mm are preferred. The geometry of the sliding seal, in particular the length of the sealing lip, is also advantageous. Overall, such relatively large opening widths can be realized in the ventilation position. A width of 55 to 65 mm is particularly preferred. The formula for a maximum opening width for soundproof ventilation can be assumed: Wmax. = B - 25mm.

A significantly larger number of hollow chambers compared to an aluminum composite construction has an advantageous effect with regard to sound insulation. By using the contact sliding strip 24, the friction of the sliding seal on the sash frame can be reduced to a minimum. This means that the material and surface structure are adapted to each other. The sliding seal preferably has a roughened surface structure on the sliding side. The system sliding strip is preferably characterized by a sliding coating. Of course, the surface structure can also be designed the other way around.

The inner chamber H7 is preferably not used directly as a ventilation duct, since this is not advantageous for soundproofing reasons. Rather, two chambers can form between the ventilation cassette wall and the outside, which are particularly preferably separated from one another by an aluminum wall.

In this respect, the following description relates in particular to preferred features and variants th, which relate to the ventilation cassette 14 or to the structure of the window, insofar as this relates to the integration of the ventilation cassette 14 in the structure of the respective ventilation window. The features of the ventilation cassettes 14 described below can be used as advantageous options on the 1 trained window can be realized or on differently structured windows. These features can also be advantageous individually and in combination, ie they can also form part of the scope of protection individually or together or be used to form it.

So shows 2 in a) and b) a side view and a perspective view of a further ventilation window, which is provided for the installation of one (or more) ventilation cassettes. A ventilation cassette 14 is in the 3 a) and b) shown.

The ventilation cassette 14 has a channel or trough-like base element 15 . This basic element 15 is designed like a box here. The base element 15 can be designed to be closed on one base side and on four sides in each case and be designed to be open on a side facing the fold in the installed state.

Provision can also be made for the respective ventilation cassette 14 to have a cover 16--in particular on this open side. One or more openings 16a can be provided in this cover 16 . With the cover 16, the base element 14 forms a box that is closed all around except for the openings 16. At least two of the openings 16a, 16b are preferably provided. Then, more preferably, the first opening 16a forms the first ventilation duct opening 9 and the other, second opening 9b forms the second ventilation duct opening 10 .

However, it is also possible for a plurality of first openings 16a to jointly form the first ventilation duct opening 9 and for a plurality of second openings 9b to form the second ventilation duct opening 10 . In this case, the first and each of the second ventilation duct openings can be interrupted by first and second webs 16c, 16d, respectively.

The base element 15 can then have a flange 151 that runs around partially or completely. The cover 16 preferably has at least one web 161 or an angled portion or a corresponding flange, with which the cover 16 rests on the edge or the flange 151 of the base element 15 in the assembled position. In this way, a defined position of the cover 16 on the base element 15 is created in a simple manner. In addition, the flange 151 of the base element 15 can serve as an advantageous insertion limitation when the base element 15 is inserted into the recess 13 of the frame - here the outer frame - so that it is easily and correctly fitted into the recess 14 during assembly (see Fig 3 ).

The interior of the ventilation cassette 14 can be adapted to these first and second openings 16a, b or not. In the latter case, the interior of the ventilation cassette is not filled but empty. This achieves a good ventilation effect.

But it can also be provided that - as already 1a explained by way of example - the interior of the ventilation cassette 14 is partially filled. In this way, the noise protection in particular can be further optimized. In addition, optional measures can be taken to clean the air flow.

An insert 141 can be inserted into the ventilation cassette with which this subdivision is achieved. The insert 141 is particularly--but not absolutely necessary--advantageous as an interchangeable insert. The insert can consist entirely or partially of a filter material 142 . Particles from the air flowing through settle on and in this as it flows through the ventilation cassette 14 . In this way, the air flow is advantageously cleaned by filtering as it flows through the ventilation cassette 14 .

The ventilation duct 8, insofar as it extends within the ventilation cassette 14, can only form a single duct there or it can in turn be subdivided into a plurality of sub-ducts 8a, 8b, 8c . . . In this way, the filter effect can be increased and the ventilation effect can be well controlled. In addition, the soundproofing can be varied in many ways in this way, in particular depending on the local conditions at the installation site, can be adapted to the external environment. For example, a ventilation window that is to be installed in a building opening that is on a busy street can have more value for good sound insulation than a window that is oriented to a quiet side of the building.

In order to optimize the soundproofing, it can be provided that the insert 141 consists not only of a single material—for example the already mentioned filter material 142—but of two or more materials. The further material can then be designed in such a way that it further optimizes the soundproofing in particular. It can thus advantageously be provided that the filter material 141 is coated on one side with a film, for example with a so-called heavy film foil. The cover 16 is preferably aligned with the frame rebate space F.

It is advantageous if the cover is releasably attached to the ventilation cassette 14, in particular if an exchangeable insert 141 is inserted into the ventilation cassette. You can also form a structural unit with the insert 141 .

It can then optionally be advantageously provided that the cover 16 is attached to the ventilation cassette 14 in such a way that it can be detached and attached again completely or almost without tools. For this purpose, for example, a type of quick-release fastener with a fastening lever can be provided, which can be rotated and latched and/or clamped under an edge of a projection of the base element 15 or the like. In this way, the insert 141 can be changed quickly and easily. However, it is also conceivable that a tool is used to change the insert, for example to loosen a screw which the cover holds on the ventilation cassette 14 .

The center seal 18 can also be fixed to the cover 16 . In particular, it has the groove 17 on its side facing the fold, in which the gasket base 21 of the corresponding (here: central) gasket 18 can be anchored. This groove can be aligned with a corresponding groove in the rebate of the frame. In this way, this groove of the window frame is advantageously not interrupted on this side of the frame and the corresponding seal can also be securely installed in the area of the ventilation cassette 14 .

What is particularly advantageous about the ventilation cassette 14 with the exchangeable insert 141 is that the insert 141 of the cassette 14 can be easily exchanged during operation and thus by the end user himself. Changing the insert is as easy as changing the filter in a vacuum cleaner. Overall, the ventilation cassette 14 itself is also easy to assemble. The ventilation cassette 14 can preferably not be positioned visibly in the fold, which in particular 2a and show b.

while showing 2a also that an additional profile 110 can be placed on the upper frame profile 1 here. This additional profile 110 can be provided in order to increase the height of the frame 1. This is advantageous because correspondingly higher ventilation cassettes 14 can be integrated into the window frame 1 in this way. Then both the window frame profile 101 and the additional profile, which is placed here outside on the upper window frame profile 101 in the installed position, have the corresponding recesses 13 for inserting the respective ventilation cassette.

The ventilation cassettes 4 are preferably mounted in the window frame and preferably only in an insulating strip zone, which is formed from insulating strips - that is to say in particular from strips made of plastic.

In order to optimize the operating comfort for a user/operator of the window, this has an electric motor drive device 30 which acts on the sash and/or sash frame and is set up to move this relative to the window frame by motor. The electromotive drive device 30 shows 2 only schematically (letter M). Such an electromotive drive device 30 is preferably integrated into the window frame profile or the casement profile or is provided on such a profile and preferably acts on a corresponding element such as the casement or the window frame via one or more transmission elements such as a rigid chain or a deployment mechanism such as a stay-opening scissor or the like a. The electromotive drive device 30 can in this respect also preferably be arranged in the rebate space in such a way that it is not visible from the outside in the closed state.

The electromotive drive device 30 is intended to reversibly adjust the casement and/or sliding frame 2 from the closed position to the ventilation position. 2 B) shows the window of 2 a) , Tilting of the casement and/or sliding frame 2 in a tilting direction 37 about a tilting axis 36 is shown schematically using dashed lines. The position of the sash and/or sliding frame 2 can be adjusted by means of a (schematically in 2 B) ) shown frame sensor 31 can be detected. This is only shown here using a sash frame 2.

The window also has a control device 32 which is set up to control the electromotive drive device 30 depending on the position of the casement and/or sliding frame 2 detected by the frame sensor 31 . As a result, the casement and/or sliding frame 2 can be automatically adjusted from the closed position to the ventilation position and back. In addition, intermediate ventilation positions, which provide for an opening of the sash and/or sliding frame 2 in intermediate positions between the closed position and the ventilation position, can be provided, into which the sash and/or sliding frame 2 can be automatically adjusted by means of the electric motor drive device 30.

The ease of use is increased even further by the fact that the window also has an environmental sensor 33 for detecting environmental conditions. The environmental sensor 33 can be arranged in the ventilation cassette 14, for example (p. 3 a) ). With the one or possibly more environmental sensor(s), environmental conditions such as a sound level inside and/or outside, the amount of air flowing through the ventilation cassette 14, the proportion of fine dust within the ventilation cassette 14, the quality of the air flowing through the ventilation cassette 14, in particular its carbon dioxide content, Fine dust content, pollutant content, allergens contained, humidity, air temperature and other vibrations acting on the ventilation cassette 14 and/or weather conditions, in particular temperature inside and/or outside, rain and/or wind can be detected. The control device 32 is set up to control the electromotive drive device 30 depending on the detected environmental conditions.

The detection of the ambient conditions and the activation of the electromotive drive device 30 of the window as a function of these enable a rapid reaction to spontaneous changes in the ambient conditions. This allows the window to automatically switch between ventilation and no ventilation of the interior of the building. The operator does not have to intervene himself, so that the change between the positions of the window is possible even when the operator is absent.

In order to be able to configure the control unit 32, it has an input and/or output interface 34 that enables wired communication, for example via a LAN, and/or wireless communication, for example via mobile radio or WLAN, with an operator unit 35. Such an operator unit 35 can be a smartphone or a tablet PC. The settings can then be made using a computer program product such as an app.
