Description

The present invention relates to a window according to the preamble of claim 1.

The aforementioned windows generally have a rotating device and / or tilting device. They are then referred to as a turn window, tilt window or turn-tilt window. Particularly large windows, in particular turn-tilt windows, are also used as balcony doors, for example.

Life in the city today is accompanied by sometimes very loud noises in everyday life. Ports, airports, road transport and industry are just some of the causes of constant noise, which can sometimes cause health and psychological damage to local residents.

For this reason, large cities and metropolitan areas make certain noise protection requirements for premises requiring protection. Adequate noise protection can usually be realized by appropriate soundproof windows.

However, as the trend is drawing in residential areas that are subject to very high noise immission (for example, in close proximity to harbors or the like), the conventional soundproof windows are reaching their limits.

The soundproofing could easily be accomplished by an infallible soundproof window with appropriate sound insulation properties. However, the acoustic contact with the outside world is prevented, which in turn is necessary for the comfort of the user. Also, no ventilation can be done through the window.

This is where the present invention sets and proposes to propose an improved window, in particular to propose a tilting window, hinged window or turn-tilt window, with which ventilation and soundproofing can be simultaneously made possible. In other words: The user should have the opportunity to open a window in the classic sense by tilting and / or turning to air and to perceive something more of the environment. Nevertheless, high sound insulation values should be achieved.

According to the invention the object is achieved by a window with the characterizing features of claim 1, characterized in that the frame is equipped with at least one ventilation duct having a first ventilation duct opening and a second ventilation duct opening, wherein the frame at least partially, preferably completely, equipped with a seal wherein the wing frame is provided with a closure means which in the first position is adapted to close at least one, preferably both, ventilation duct openings, wherein the wing frame in the second position is adapted to release the ventilation duct openings and abut the seal. The resulting gap between the sash and frame is formed by tilting or turning the opening of the wing by means of a seal and it is an effective reduction of sound transmission, in particular insulation of the incoming noise possible. For ventilation, a diversion takes place via a ventilation channel embedded in the window frame, which is preferably lined with sound-absorbing material. The ventilation duct is designed in such a way that it is exposed only when the window is tilted or turned and when closed it allows neither sound transmission nor ventilation.

Accordingly, the user does not have to forego contact with the outside world, such as ventilation, and is furthermore protected against excessive noise immission.

Insofar as the terms "outside" (A) and "inside" (I) are used, this refers to the orientation of the component, in particular in the interior of a building or in the direction outside the building, that is to say the ambient air.

A window according to the invention essentially comprises a window frame 1, a sash frame 2 with a surface element 22, for example an insulating glass pane, and preferably a tilting device or a rotating device or a tilting / turning device. In this respect, the casement 2 is either tilted and / or rotatably received in the frame 1.

In a conventional installation position of the window of the sash 2 relative to the frame 1 on the tilting device or the Tilting or tilt-rotating device between a closed and an open state tilted or rotated. The tilting axis 3 is usually horizontal, the axis of rotation corresponding vertical. However, the opening of the window by means of the rotating device is much larger than the opening of the window with the tilting device. Neither the tilting device, nor the rotating device or the tilt-turn device as such are shown explicitly in the figures. However, the individual devices are sufficiently well known to the person skilled in the art, so that they need not be discussed further here.

The frame 1 usually comprises four frame elements, which are joined together to form a rectangular frame. As such, each frame element as a rule comprises a first profile 111, a second profile 112 and one or more insulating webs 113 connecting the profiles. The frame is generally inserted into an opening in a masonry. The first profile 111 can be addressed as an outer profile and the second profile 112 as an inner profile due to the intended orientation of the window.

Also, the sash usually includes four
Sash members joined together to form a rectangular frame. As a rule, each wing frame element as a rule comprises a first profile 211, a second profile 212 and one or more insulating ribs 213 connecting the profiles. The planar element 22 is inserted in the wing frame, as a rule an insulating glass pane. The first profile 211 can be addressed as an outer profile and the second profile 212 as an inner profile due to the intended orientation of the window.

The profiles are usually made of aluminum, whereas the insulating bars are usually made of plastic. But other suitable materials, such as wood, are conceivable.

Below will be discussed first on the execution of the window with a tilting device.

Of particular interest in the following is the upper horizontal frame element which is to be designated in the figures by the reference numeral 11 in a conventional mounting position of the window, and also the upper horizontal sash element which shall be designated by the reference numeral 21 in the figures.

As already shown above, the casement 2 is tiltably received in the frame 1 via the tilting device. In a conventional installation position of the window, the tilting axis 3 is parallel to the lower horizontal frame or wing frame element of the window. In this respect, the upper horizontal sash element 21 represents that sash element which is arranged on the side of the sash frame 2 opposite the tilt axis 3. Accordingly, the upper horizontal frame member is parallel to the sash member 21 and closest frame member 11 is.

With the tilting device provided for tilting the sash frame 2 in the frame 1, the sash frame 2 can be tilted about a tilting axis 3 between a first position and a second position. The first position should correspond to the closed window.

In a tilted state of the sash 2 results in conventional windows according to a gap between the upper horizontal frame member 11 and the upper horizontal sash member 21. This gap is the largest part of the ventilation.

However, the ventilation in this area is solved differently in the window according to the invention. It is provided that the frame 1, in particular the frame member 11, is equipped with at least one ventilation duct 12 having a first ventilation duct opening 121 and a second ventilation duct opening 122, wherein the frame 1, in particular the frame member 11, with a wing frame 2, the sash frame element 21, in particular the sash frame element 21, is equipped with a closure means 214, which in the first position is arranged to close at least one, preferably both, ventilation channel openings 121, 122, wherein the sash frame 2, in particular the sash member 21, in the second position is adapted to open the ventilation duct openings 121, 122 and to abut the gasket 114.

The closure means 214 can be designed differently. It can be formed for example by the insulating web 213 of the sash member 21, a stop seal 4 and / or in cooperation with the seal 114 or parts of the seal 114. Ultimately, it is about the ventilation through the ventilation duct with the window closed, ie the wing frame in its first position to prevent and release in the second position.

By means of this embodiment of the window according to the invention, the following effect can be achieved. With the window closed, which corresponds to the first position of the sash 2, the soundproofing is essentially guaranteed as in a non-openable window, but there is no ventilation. When the wing frame 2 is tilted to the second position, the closure means 214 releases the vent channel openings 121, 122, but the seal 114 of the upper horizontal frame member 11 is directly or indirectly in contact with the upper horizontal wing frame member 21, so that ultimately no gap exists between the uppermost horizontal frame member 11 and the top horizontal sash member 21 is formed by the air, as in a conventional window which is tilting, can be replaced. Rather, this gap is closed by the seal 114, so that a sound insulation takes place, however, a ventilation via the ventilation duct 12 can equally take place. The ventilation channel 12 acts as a bypass on the closed by the seal 114 gap, so to speak. Correspondingly, the seal 114 is arranged between the first ventilation channel opening 121 and the second ventilation channel opening 122 relative to a viewing angle from the outside to the inside of the window. In other words, the first ventilation channel opening 121 is provided on the side facing the outside in the Fensterfalz the window frame 1 and the window frame member 11, while the second ventilation channel opening 122 on the inner side facing the Fensterfalz the window frame 1 and the window frame member 11 is arranged ,

It has initially been assumed above that the opened tilting position corresponds to the second (tilting) position of the casement in which the ventilation duct openings 121, 122 are released and the sash at least partially abuts the seal 114. This does not necessarily have to be this way. It can be provided, for example, that the tilt angle, that is, the angle occupied by the casement 2 in the second position, is less than in a conventional tilting window or a further open tilting exists, in which the tilt angle is even greater than in the second Position is configured, but the seal 114 is no longer applied to the sash, in particular the upper sash member. This can be realized for example by a switchable limiter, not shown, in the tilting mechanism. If, for example, the limiter is activated, the sash frame can only be tilted into the second position. The ventilation takes place via the ventilation duct 12. If the limiter is deactivated, the sash can be tilted further into the open position. The window according to the invention ventilates like a conventional window.

In the second position, a portion of the sash element 21 is preferably left under the frame member 11 so that the seal 114 may rest on the sash 2. A preferred distance between the sash element and the frame member is 40 to 50mm, in particular 45mm. The distance is the dimension S in the Fig. 2 located. It could also be said that the track section S, which is to be covered by the top edge of the sash when tilting between the first and the second position, should be a maximum of 40 to 50mm, preferably 45mm. This could be achieved by the delimiter already outlined above.

The ventilation principle outlined above for a tilting window can also be applied to a rotating window and, of course, to a turn-tilt window transfer. An application in a window with a parallel-setting device for the sash is conceivable.

In essence, it is preferably provided here that the window has the turning means arranged to rotate the sash frame 2 in the frame 1 with a rotation axis 3a about which the sash frame can be rotated between the first position and the second position, the sash frame 2 being a sash member 21a, which is arranged on the side opposite the axis of rotation 3a side of the sash 2, wherein the frame 1 has a to the sash member 21a parallel and closest lying frame member 11a with the seal 114. Again, the sash frame from the first position, which corresponds to the closed window, are rotated to a second position in which the ventilation duct openings 121, 122 are released and the sash at least partially, preferably the sash member 21 a, rests against the seal 114.

Again, it can be provided that a switchable limiter is provided in the rotating device, with which the rotation angle can be selectively limited to the path between the first position and the second position, in particular to the already mentioned measure S. In this case, the ventilation is done via the ventilation channel 12. With the limiter deactivated, the sash can be swung further as known from a conventional window. In this case, of course, the seal 114 is no longer on the sash 2. The ventilation is quite ordinary, but of course no longer soundproofed, over the open window.

As such, the ventilation duct 12 does not necessarily have to be designed as a continuous, sheathed pipe. Rather, a number of openings in the frame member 11, in particular in the insulating webs 113 and profiles 111, 112, the ventilation duct 12 form.

It can also be provided that numerous, over the length of the frame 1 or the frame members 11 and 11a distributed first and second ventilation duct openings 121, 122 are provided, which can ultimately be closed or released together by the one or more closure means (s) ,

The seal 114 is preferably attached to the first frame member 11 or 11 a and preferably extends over the entire length of the frame member 11 or 11 a. It can also be provided that the seal 114 is attached to the entire window frame 1, that is to say on all four frame elements, or even only to one or one. Finally, there is a seal 114 makes sense where in a second position of the sash 2, an otherwise forming gap can be closed. The seal 114 is preferably a very extensible seal made of an elastic material, preferably a hollow chamber seal.

It may further preferably be provided that the ventilation duct 12 at least in sections, preferably the outwardly directed side of the ventilation duct 12, with a means 5 for preventing or reducing condensation, such as synthetic rubber (EPDM - ethylene-propylene-diene rubber ), is pasted. By this measure, the formation of condensation in this area can be reduced or avoided.

It may further be provided that the ventilation duct is formed at least in sections by an acoustic absorber element arrangement comprising one or more acoustic absorber elements. As a material for the acoustic absorber element arrangement is for example mineral fiber in question. This can be avoided or at least reduced that sound is transmitted with tilted or rotated window on the ventilation duct. Also, the ventilation duct in the flow direction may have different cross sections and / or deflections. These measures can also contribute to a reduction of sound transmission through the ventilation duct.

The ventilation duct openings 121, 122 are usually provided in the Fensterfalz. However, other locations are also conceivable, but it should be ensured that these are closed in a first position of the casement 2 and opened in a second position of the casement 2.

The arrangement of the seal 114 and the ventilation channel 12 can basically also be configured vice versa or even crosswise, ie the seal 114 and the ventilation channel 12 on or in the sash 2 or the seal 114 on the sash 2 or the frame 1 or the ventilation duct 12 in the casement 2 or the frame 1.

It may further be provided that the ventilation channel 12 has different cross sections in the flow direction. This measure can also contribute to the reduction of sound transmission.
