Description

The present invention relates generally to a window.

The pamphlet DE 10 2013 114 250 A1 relates to a rebate ventilator for a window or a door, the rebate ventilator being designed to be attached to a frame or to a sash of the window or the door and defining an air duct for an air flow running through a rebate of the window or the door. At least one flow-limiting valve is arranged in the air duct, which comprises a closing element which is movable between an open position and a closed position and which can be moved in the direction of the closed position by a strong air flow. The closing element is arranged in the area of a narrow point of the air duct in such a way that it is moved in the direction of the closed position when a strong air flow occurs due to the Venturi effect.

The pamphlet DE 10 2006 050 572 A1 relates to a profile frame composed of several mitered hollow profiles with an outer profile chamber on the outside of the frame, with an antechamber adjacent to the outer profile chamber, separated from it only by a separating web, and with one in each case into the outer profile chamber and the antechamber of two mitred hollow profiles inserted corner connector. The profile frame furthermore comprises at least one hole penetrating the outer profile chamber in the area of the corner connector and the miter joint for the supply of adhesive, and a recess breaking through the separating web as a connection opening between the outer profile chamber and the antechamber for gluing both corner connectors in one operation.

The pamphlet DE 198 21 649 A1 relates to a device for ventilating rooms, preferably kitchens, on a tilt and turn sash window. The kitchen fumes and smells reach the area of the tilt and turn sash via an extractor hood and a fan using a duct system. In the device for ventilating rooms, an exhaust air pipe connects to the duct system at the upper edge of the casement on the lintel. This exhaust air pipe has an opening at the level of the window frame, on which a pivotable air control part is provided in the direction of the tilting gap of the sash. By means of this device attached to the available space on a tilt and turn sash window, kitchen fumes and odors can be transported away from the corresponding space above the tilted window sash without breaking through the wall.

The pamphlet DE 198 20 434 A1 relates to a parallel vent window arrangement which has a double-shell window and a frame. Furthermore, a plurality of seals attached to the frame and / or a plurality of seals attached to the window are provided. At least one of the seals extends, at least in sections, largely perpendicular to the pane surface and / or at different distances with respect to other seals in the direction of the window or the frame, and when the window is closed, the seals act at least partially with seals and / or sections for sealing on the window or the frame together and, when the window is open, form a labyrinth seal, the opening properties of which can be influenced by the opening state of the window. Furthermore, at least one seal of the frame and / or the window is designed as a water-repellent barrier.

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

Nowadays life in the big city is accompanied by very loud noises in everyday life. Ports, airports, road traffic and industry are just a few of the causes of constant noise emissions that can sometimes cause health and psychological damage to residents.

For this reason, large cities and metropolitan areas have certain noise protection requirements for premises in need of protection. Appropriate noise protection can usually be achieved through appropriate soundproof windows.

However, since there is a trend towards residential areas that are subject to very high levels of noise pollution (e.g. in the immediate vicinity of harbors or similar), conventional soundproof windows are reaching their limits.

The soundproofing could easily be achieved by a soundproof window that cannot be opened with appropriate soundproofing properties. However, acoustic contact with the outside world is prevented, which in turn is necessary for the comfort of the user. Ventilation through the window is also not possible.

This is where the present invention comes in and makes it its task to propose an improved window, in particular to propose a tilt window, turn window or turn-tilt window ventilation and soundproofing can be made possible at the same time.

In other words: The user should be able to open a window in the classic sense by tilting and / or rotating it in order to ventilate and to perceive a little 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 features of claim 1. It is provided, inter alia, that the window frame is equipped with at least one ventilation duct which has a first ventilation duct opening and a second ventilation duct opening, the window frame being at least partially, preferably completely, equipped with a seal, the casement frame being equipped with a closure means, which is set up in the first position to close at least one, preferably both, ventilation duct openings, the casement being set up in the second position to release the ventilation duct openings and to rest against the seal. The gap between the sash frame and the window frame that occurs when the sash is opened by tilting or rotating it is closed by means of a seal and an effective reduction in sound transmission, in particular insulation of the incoming noise, is made possible. For ventilation, a diversion takes place via a ventilation duct embedded in the frame, which is lined at least in sections with sound-absorbing material. The ventilation duct is designed in such a way that it is only exposed when the window is tilted or rotated and does not allow sound transmission or ventilation when the window is closed. The user does not have to forego contact with the outside world, such as ventilation, and is also protected from excessive noise pollution.

Further advantageous configurations of the proposed invention emerge in particular from the features of the subclaims.

In an advantageous embodiment of the proposed invention, it can be provided that the window frame comprises several, preferably four, window frame elements which are combined to form a rectangular window frame, the sash frame comprising several, preferably four, wing frame elements which are combined to form a rectangular wing frame.

In a further advantageous embodiment of the proposed invention it can be provided that the seal of the frame element facing the sash element is a seal arranged in the window rebate, in particular a central seal, which can be formed in one piece or in several pieces. Such a seal is advantageously suitable for resting on a casement in a second position.

In a further advantageous embodiment of the proposed invention it can be provided that the first ventilation duct opening and the second ventilation duct opening are opened in the window rebate. In this way, the ventilation duct openings are generally not visible, so that the window does not visually differ from a window according to the prior art when viewed in a conventional manner.

In a further advantageous embodiment of the proposed invention, it can be provided that the path between the first position and the second position of the sash relative to the frame, measured over the track section from the top or side edge of the sash when tilting or rotating is covered, 40 to 50 mm, preferably 45 mm. By limiting the angle of rotation or tilting, it can be ensured that a seal does not have to be designed to be excessively protruding in order to be able to rest against the casement.

In a further advantageous embodiment of the proposed invention it can be provided that the seal is arranged between the first ventilation duct opening and the second ventilation duct opening.

Closure means

To the extent that the terms “outside” (A) and “inside” (I) are used here, this refers to the orientation of the component in particular in the interior of a building or in the direction outside the building, i.e. towards the ambient air.

A window according to the invention essentially comprises a frame 1 , a casement 2 with a surface element 22nd , for example an insulating glass pane, and preferably a tilting device or a rotating device or a tilting-rotating device. In this respect, the casement is 2 optionally tiltable and / or rotatable in the frame 1 recorded.

In a normal installation position of the window, the casement 2 opposite the frame 1 be tilted or rotated between a closed and an open state via the tilting device or the turning device or tilting-turning device. The tilt axis 3 Usually runs horizontally, the axis of rotation accordingly vertically. The opening of the window by means of the rotating device is, however, significantly larger than the opening of the window with the tilting device. Neither the tilting device nor the turning device or the tilting-turning device as such are explicitly shown in the figures.

However, the person skilled in the art is sufficiently familiar with the individual devices so that they do not have to be discussed in more detail at this point.

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

The sash frame also usually comprises four sash frame elements which are joined together to form a rectangular frame. Each sash element as such generally comprises a first profile 211 , a second profile 212 and one or more insulating webs connecting the profiles 213 . The surface element is in the casement 22nd used, usually an insulating glass pane. The first profile 211 can be used as the outer profile and the second profile due to the intended orientation of the window 212 can be addressed as an inner profile.

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

In the following, the design of the window with a tilting device will first be discussed.

Of particular interest in the following is the upper horizontal frame element in a customary installation position of the window, which is shown in the figures with the reference number 11 is to be designated, furthermore the upper horizontal sash element, which in the figures with the reference number 21st should be designated.

As shown above, the casement is 2 Tiltable in the frame via the tilting device 1 recorded. The tilt axis runs in a normal installation position of the window 3 parallel to the lower horizontal frame or sash element of the window. In this respect, the upper horizontal sash element represents 21st that sash element which is on the tilt axis 3 opposite side of the sash 2 is arranged. Accordingly, the upper horizontal frame element represents that of the sash element 21st parallel and closest frame element 11 represent.

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

In a tilted state of the sash 2 With conventional windows, a gap is created between the upper horizontal frame element 11 and the upper horizontal sash element 21st . Most of the ventilation takes place through this gap.

The ventilation in this area is, however, solved differently in the window according to the invention. It is provided that the frame 1 , especially the frame element 11 , with at least one ventilation duct 12 is equipped, which has a first ventilation duct opening 121 and a second ventilation duct opening 122 having, wherein the frame 1 , especially the frame element 11 , with one of the casement frames 2 , especially the sash element 21st , facing seal 114 is equipped, the casement 2 , especially the sash element 21st , with a closure means 214 is equipped, which is set up in the first position, at least one, preferably both, ventilation duct openings 121 , 122 to close, with the casement 2 , especially the sash element 21st , is set up in the second position, the ventilation duct openings 121 , 122 to release or open and on the seal 114 to lie on.

The closure means 214 can be designed differently. It can, for example, through the insulating bar 213 of the sash element 21st , a stop seal 4th and / or in conjunction with the seal 114 or parts of the seal 114 are formed. Ultimately, it is a matter of preventing ventilation through the ventilation duct with the window closed, i.e. the casement in its first position, and releasing it in the second position.

This embodiment of the window according to the invention can achieve the following effect. With the window closed, what the first position of the sash 2 corresponds, the sound insulation is essentially guaranteed as with a window that cannot be opened, but there is no ventilation. Will the casement 2 tilted into the second position, gives the locking means 214 the ventilation duct openings 121 , 122 free, but the seal lies 114 of the upper horizontal frame element 11 on the upper horizontal sash element 21st directly or indirectly, so that ultimately there is no gap between the uppermost horizontal frame element 11 and the top horizontal sash element 21st arises through which air can be exchanged, as in a conventional tilted window. Rather, this gap is through the poetry 114 closed so that sound insulation takes place, but also ventilation via the ventilation duct 12 can take place. The ventilation duct 12 acts like a bypass to the one through the seal 114 closed gap over. The seal is accordingly 114 , based on a viewing angle from the outside to the inside of the window, between the first ventilation duct opening 121 and the second ventilation duct opening 122 arranged. In other words, the first air duct opening is 121 on the side facing the outside in the window rebate of the window frame 1 or the frame element 11 provided while the second ventilation duct opening 122 on the side facing the inside of the window rebate of the window frame 1 or the frame element 11 is arranged.

It was initially assumed above that the opened tilt position corresponds to the second (tilt) position of the sash in which the ventilation duct openings 121 , 122 are released and the sash frame at least in sections on the seal 114 is applied. This does not necessarily have to be the case. It can be provided, for example, that the tilt angle, i.e. the angle that the sash frame 2 occupies in the second position, is designed less than in a conventional tilt window or there is a further open tilt position in which the tilt angle is designed even greater than in the second position, the seal 114 but no longer rests against the casement, in particular the upper casement element. This can be implemented, for example, by a switchable limiter (not shown) in the tilting mechanism. If, for example, the limiter is activated, the casement can only be tilted into the second position. The ventilation takes place via the ventilation duct 12 instead of. If the limiter is deactivated, the casement can be tilted further into the open position. The window according to the invention ventilates like a conventional window.

A section of the sash element should preferably be in the second position 21st under the frame element 11 remain so the seal 114 on the sash 2 can rest. A preferred distance between the casement element and the frame element is 40 to 50mm, in particular 45mm. The distance is with the measure S. in the 2 drawn. It could also be said that the railway section S. , which should be covered from the upper 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 tilt window can also be transferred to a turn window and, accordingly, of course to a turn-tilt window. An application in a window with a parallel storage device for the casement is also conceivable.

Essentially, it is preferably provided here that the window is used for rotating the sash 2 in the frame 1 established rotating device with a rotation axis 3a has about which the sash can be rotated between the first position and the second position, the sash 2 a sash element 21a having which on the axis of rotation 3a opposite side of the sash 2 is arranged, the frame 1 one to the sash element 21a parallel and closest outer frame element 11 a with the seal 114 having. Here, too, the casement can be moved from the first position, which is the one in which the ventilation duct openings 121 , 122 are released and the sash frame at least in sections, preferably the sash element 21a , on the seal 114 is applied.

Here, too, provision can be made for a switchable limiter to be provided in the rotating device, with which the angle of rotation can be optionally limited to the path between the first position and the second position, in particular to the extent already mentioned S. . In this case, ventilation takes place accordingly via the ventilation duct 12 . With the limiter deactivated, the window sash can be pivoted further, as is known from a conventional window. In this case the seal lies 114 of course no longer on the casement 2 on. The ventilation takes place quite normally, but of course no longer soundproofed, through the open window.

The ventilation duct 12 as such, it does not necessarily have to be designed as a continuous, jacketed pipe. Rather, a number of openings in the frame element 11 , especially in the insulating bars 113 and profiles 111 , 112 , the ventilation duct 12 form.

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

The seal 114 is preferably on the first frame element 11 or. 11 a attached and preferably runs over the entire length of the frame element 11 or. 11a . It can also be provided that the seal 114 on the entire frame 1 , that is to say is attached to all four frame elements or only to individual or one. After all, there is a seal there 114 useful where in a second position of the sash 2 an otherwise forming gap can be closed. It is the poetry 114 preferably a very elastic seal made of an elastic material, preferably a hollow chamber seal.

It can also 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 to prevent or reduce condensation, such as synthetic rubber (EPDM - ethylene-propylene-diene rubber), is glued. This measure can reduce or avoid the formation of condensation in this area.

It can 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. Mineral fiber, for example, can be considered as the material for the acoustic absorber element arrangement. In this way it can be avoided or at least reduced that sound is transmitted via the ventilation duct when the window is tilted or rotated. The ventilation duct can also have different cross-sections and / or deflections in the direction of flow.

These measures can also contribute to a reduction in the transmission of sound via the ventilation duct.

The ventilation duct openings 121 , 122 are usually provided in the window rebate. However, other locations are also conceivable, but it should be ensured that these are in a first position of the sash 2 locked and in a second position of the sash 2 are open.

The arrangement of seal 114 and ventilation duct 12 can basically also be designed vice versa or even crosswise, i.e. the seal 114 and the ventilation duct 12 on or in the casement 2 or the seal 114 on the casement 2 or the frame 1 or the ventilation duct 12 in the casement 2 or the frame 1 .

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