Description

The invention relates to a window with a ventilation duct according to the preamble of claim 1.

Such a window, which enables sound-insulated ventilation in a tilted or rotated sash position, is known per se, for example from US Pat DE 10 2016 115 422 . However, the generic construction has a relatively complicated structure.

In addition, the known construction requires relatively large actuation forces when closing the sash. It is particularly disadvantageous that the center seal of the window frame slides rather poorly on the insulating web of the sash frame. Another disadvantage to be mentioned is the relatively small opening width in the ventilation position. The opening width is limited, among other things, by the (short) insulating web of the sash as a sliding surface.

The invention is therefore intended to take a different approach and create an optimized window with a ventilation duct.

The invention achieves this aim by the subject matter of claim 1.

Such a window is created that has at least the following features:

1. a) a frame composed of several frame profiles,
2. b) a casement composed of several frame profiles, which preferably has at least one surface element and which is movable relative to the frame at least between a closed position and a ventilation position,
3. c) wherein a circumferential frame rebate space is formed between the frame profiles of the window frame and the frame profiles of the casement, which has a first rebate space section which is arranged essentially perpendicularly or perpendicularly to a plane which is formed by the surface element,
4. d) and the casement and the frame - cooperating - are designed to release at least one ventilation duct in a ventilation position and to close the at least one ventilation duct in the closed position,
5. e) with a further rebate section F _III is formed between at least one of the frame profiles and at least one of the sash profiles or - if available - a facing shell of the sash parallel or essentially parallel to the plane of the surface element,
6. f) and wherein in the further rebate section of feature e) an absorber block is attached to the window frame profile or the sash profile or the facing shell and / or is inserted into this and that an absorber element is placed on the sash profile or the facing shell or the window frame profile and / or is inserted into it, the absorber element engaging in the absorber block when the window is closed,
7. g) and wherein the absorber block and the absorber element in the open state of the window in the further rebate space section of the feature e) release the ventilation duct and close in the closed state of the window.

The advantageous absorber element, which engages in the absorber block when the window is closed and closes the ventilation duct, and which engages less in the absorber block when the window is open, so that a gap is created, thereby releasing the ventilation duct, results in an advantageous arrangement that saves space of the ventilation duct with very good ventilation and particularly noteworthy soundproofing properties.

The concept of the window is not too narrow. It comprises elements with a frame and a sash frame that is movable relative to it. The frame can be designed circumferentially or not designed circumferentially as in the case of a door. In the sense of this document, a door is therefore also a window. The window can be built into a wall opening of a wall or wall of a building. However, it can also be designed as part of a facade or can be built into such a facade. The frame itself can thus also form part of a facade structure.

The features e) to g) are preferably implemented at least or only on an upper frame section of the window in the installed position.
It can be provided that the absorber block is inserted into a housing which is inserted into the frame profile. This results in simple assembly of the absorber block in and space-saving accommodation in the frame profile.

It can advantageously be provided that the absorber element has an essentially wedge-shaped cross section and that the absorber block has a cross section that corresponds geometrically to the absorber element Has wedge-shaped incision or a recess. This gives the absorber element a structurally simple geometry that supports a tilting movement of the sash towards the frame without the absorber element having to deform during the movement. In addition, very good sound-absorbing properties are achieved.

According to a further option of the invention it can be provided that the ventilation duct runs in such a way that it causes at least one change in direction of an imaginary flow line between 45 ° and 90 ° and particularly preferably at least two such changes in direction. The one or more changes in direction of the air flowing through the ventilation duct effectively insulate disruptive sound.

It can advantageously be provided that the absorber element and the absorber block are designed in the manner of a ventilation cassette which is inserted into a recess in the frame profile. This results in a simple assembly of the absorber element and the absorber block in the respective frame profile.

According to a further option, it can advantageously be provided that several ventilation cassettes are provided per frame profile or on several sides per frame. This makes it possible to equip the ventilation openings that are perpendicular to the tilt axis of the sash when the sash is tilted to be sound-absorbing as well.

It can further advantageously be provided that the absorber element has a wave-like structure on the flanks of its wedge-shaped cross section and the absorber block has a wave-like structure that corresponds geometrically to this in its incision. The wave-like structures have a sound-absorbing effect and are easy to manufacture.

It is also advantageous that the absorber element has a rectangular envelope geometry in cross section. This results in a structurally particularly simple cross-sectional geometry.

According to a further advantageous option, it can be provided that the absorber element has a wave-like structure arranged symmetrically to an imaginary center plane of the cross section on its flanks. The wave-like structures have a sound-absorbing effect and are easy to manufacture.

It is also advantageous if the absorber element has an opening at the wave troughs of this wave-like structure. The openings ensure good ventilation properties.

According to a further advantageous option, it can be provided that the absorber element has a seal at its free end which, when the window is open, seals the rebate area against the incision so that the air flowing through the ventilation duct must necessarily flow through the respective opening. This ensures in a structurally simple manner that the air flow has to flow through the openings and is thus divided, which in turn has a sound-absorbing effect.

According to a variant, it can advantageously be provided that the absorber element is designed as a bellows, which is fastened with a first end to the foot of the absorber element and a second end is fastened to a base of a housing that is inserted into the incision of the absorber block. The folds have a sound-absorbing effect, and the bellows structure also gives the absorber block a high degree of flexibility and thus reliable functionality when the sash is tilted and back.

It is also advantageous if the absorber element has a support and guide element which supports and guides the bellows during the opening and closing movement of the wing and which engages in an opening in the absorber block provided for this purpose. This prevents the bellows from jamming or even tearing off during the tilting movement of the sash and back into a closed position with a high degree of security.

It can also be provided that the ventilation duct runs through one or more C-shaped duct-like opening (s) in the absorber block which is delimited by the housing towards the frame profile. As a result, the air flow in the ventilation duct is inevitably diverted at least four times, effectively insulating the sound.

According to a further embodiment of the invention, the absorber element is designed as a shut-off element. This results in a structurally simple absorber element.

According to a further option, it can be provided that the shut-off element is fastened with a first end to the foot of the absorber element and also engages in an opening provided for this purpose in the absorber block when the wing is open. As a result, the opening between the sash and the frame, which results in the tilted position of the sash, is blocked off easily and effectively.

The opening preferably has an enlargement which is wedge-shaped in cross section and which serves to guide the shut-off element. This will result in unintentional deformation of the shut-off element when the sash is moved into its closed position, it is simply avoided in terms of design.

In a preferred embodiment of the invention, the absorber element is made from a foamed plastic, an elastomer or a thermoplastic plastic. As a result, the absorber element itself has sound-absorbing properties.

According to one variant, it can advantageously be provided that the frame profile and the sash profile each have a first metal shell and a second metal shell and that these two respective metal shells are connected to one another via an insulating web or several insulating webs. This creates a permanently robust, easy-care composite profile with good thermal insulation properties. It can also be provided that the frame profile and the sash profile each have a metal profile plane and an insulating profile plane or three metal profile planes and two insulating profile planes. As a result, the thermal insulation properties and the required installation space of the profiles can be adapted to the respective requirements with structurally simple means.

It can advantageously be provided that the frame profiles preferably have at least three or more hollow chambers between the room side I and the room II H1 , H2 , ... exhibit. This results in profiles with good thermal insulation properties with simple structural means.

The ventilation duct opens, for example, when the sash is moved into an open position, by tilting the window or the sash frame tilted (lower horizontal axis of rotation, opening inwards), or optionally or alternatively by turning around a vertical axis of rotation (rotary window) Folding (lower horizontal axis of rotation, opening outwards), or pivoting (lower horizontal axis of rotation of the sash) or sliding (e.g. parallel opening)

It can also advantageously be provided that in the frame rebate space F. a central seal is arranged, which is attached to the frame profile and is attached to the insulating web, so that the central seal divides the frame rebate space into a first and a second area. As a result, the tightness and thus the thermal insulation properties of the window are improved by a simple measure. Further advantageous embodiments of the invention can be found in the remaining subclaims.

Between the frame 1 and the casement 2 or their frame profiles 100 , 200 is a preferably circumferential frame rebate in the respective exemplary embodiments F. educated. With the frame rebate F. it is a stepped frame rebate F. , which is explained in more detail below.

The respective window of the 1 until 5 is used to be able to close and open a room opening of a building (not shown here), whereby a room I (for example an area surrounding a building) is separated from a room II (for example an interior of the building).

In the following, the terms "frame profile 100" and "frame 1" as well as "sash profile 200" and "sash 2" are also used interchangeably. This is because the means and configurations discussed below can each preferably run around or in sections on the frame 1 or on the casement 2 be trained. You can only use one of the corresponding frame profiles of the casement 2 and the frame 1 be formed (for example on the frame profiles opposite a hinge axis) or on several of the corresponding frame profiles of the sash frame 2 and the frame 1 be trained.

The casement 2 can - preferably to one side or to an adjoining room II - a contact web 4th have, with which it is in the closed position on the frame 1 directly or via one on the casement 2 attached stop seal 5 is applied. Analogously - preferably to the other side or to the other adjoining room I - the window frame 1 a landing stage 6th have, in which it is in the closed position on the frame 1 directly or via one on the landing stage 6th attached stop seal (not shown here) is applied. Such a gap will be in each case S _II and a crack S _I between the frame rebate F. and the room I or II tightly closed.

It is preferably provided that the stop seal 5 is designed circumferentially, so on four sides of the sash 2 runs.

The stop seal 5 can advantageously be made from a weldable TPE or weldable EPDM. So can the sash profile 200 with inserted stop seal 5 at the same time to a casement 2 be welded.

the 1a and the 1b each show a section through a composite profile construction consisting of the frame profile 100 and the sash profile 200 .

The frame profile 100 can - as in 1a and 1b shown - in this variant a first metal shell 102 and a second metal shell 103 exhibit. These two metal bowls 102 and 103 can via an insulating bar 104 (or several insulating bars) must be connected to one another. The sash profile 200 can also have a first metal shell 202 and a second metal shell 203 exhibit. These two metal bowls 202 and 203 are over an insulating bar 204 (or several insulating bars) connected to one another. The first metal bowls 102 , 202 can be oriented to an outside or room I of a building when installed, and the second metal shells 103 , 203 can be oriented to an inside or room II of a building.

The construction method described here is preferred, in which two metal profile levels are connected to one another via an insulating level, which is usually 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 and designs with three metal profile levels and two insulating profile levels.

These composite profiles 100 , 200 preferably have at least three or more hollow chambers H ₁ , H ₂ , .... between the room side I and the room II. on. According to the embodiment of 1 a and 1b three hollow chambers H ₁ to H _{3 are provided} between room I and room II (“from inside to outside”). Also perpendicular to the direction I-II, especially in the area of the contact webs 4th , 6th further hollow chambers can be formed. The hollow chambers H ₁ , H ₂ , ... as well as the insulating bars 104 , 204 between the metal shells 102 , 103 respectively. 202 , 203 each and in combination ensure very good thermal insulation properties.

Depending on the structure of the composite profiles 100 , 200 one or more further hollow chambers can also be provided. One or more of these further hollow chambers can advantageously be in the respective contact web 4th or 6th be provided. These measures improve the soundproofing and the thermal insulation, each or together.

As a material for the metal shells 102 , 103 respectively. 202 , 203 light metals are suitable. The light metal aluminum is particularly preferred. As a material for the insulating bars 104 respectively. 204 plastic is provided.

The composite profiles 100 , 200 then preferably have an essentially continuous light metal outer wall towards a first room side I and preferably also have an essentially continuous light metal outer wall towards a second room side II.

In the frame rebate section F _I , F _II , which is parallel to the x-axis of the coordinate system in 1a or perpendicular to the plane of the surface element 3 between the frame profiles 100 , 200 is a center seal 105 arranged. It can be attached to the frame profile 100 be attached and on the insulating bar 104 be attached. It can be provided that on the insulating web 104 a fastening means, in particular an undercut groove 106, for fastening the center seal 105 is trained. The center seal 105 forms in interaction with a counter sealing surface 205 that is the sash profile here 200 or the insulating bar 204 forms a kind of system seal.

It is preferably provided that the center seal 105 is designed circumferentially, so on four sides of the window frame 1 runs.

The center seal 105 can advantageously be made from a weldable TPE or weldable EPDM. So can the frame profile 200 with inserted center seal 105 at the same time to a frame 2 be welded.

The center seal 105 can be a gasket base 1051 with one or more sealing feet 1052 have, which is / are inserted into the groove 106 / are. The center seal 105 can also have one on the seal base 1051 attached sealing section 1053 exhibit. This can be designed as a single sealing lip or as a combination of two or more sealing lips. The sealing section 1053 can in particular have a sealing lip which is designed to be curved in itself and / or again has a joint section, so that it is divided into two lip areas that are movable relative to one another and that connect to form a longer lip.

The sealing section 1053 is in the closed state of the window (see 1a) on a mating sealing surface 205 at. The counter sealing surface can be from an insulating bar 204 of the sash profile 200 be shaped.

The center seal 105 thus divides the frame rebate space F. into a first and a second area F _I , F _II (according to the orientation to rooms I and II), both parallel to the x-axis of the coordinate system or perpendicular to the plane of the surface element 3 are arranged. These areas also jointly form a first rebate space section F _I , F _II , which is perpendicular or substantially perpendicular to the surface element.

On the sash profile 200 is a cladding here 201 attached. The facing shell 201 is preferably designed as a further metal shell. The facing shell can be screwed to the sash profile 200 be attached. The facing shell 201 has another stop seal 7th on that in a corresponding groove 8th is used.

It is preferably provided that the stop seal 7th is designed circumferentially, so on four sides of the sash 2 runs.

The stop seal 7th can advantageously be made from a weldable TPE or weldable EPDM. So can the sash profile 200 with attached cladding 201 and with inserted stop seal 7th at the same time to a casement 2 be welded.

It's another rebate section F _III between the frame profile 100 and the sash profile 200 or the offset shell 201 parallel to the y-axis in relation to the coordinate system in 1a or parallel to the plane of the surface element 3 is formed. The seam space sections F _I , F _II on the one hand and F _III on the other hand together form the rebate space. The stop seal 7th seals the rebate section F _III away. The rebate section F _III is also through the stop seal 5 from the frame rebate F. respectively. F _II between the Frame 1 or frame profile 100 and the casement 2 or the sash profile 200 is formed in the closed state of the window, separately. Instead of the metal shell facing room II 203 attached cladding 201 the metal shell directed towards room II can also be designed with an integrally molded long stop leg.

In the facing shell 201 of the sash 2 is a foot 9 an absorber element 10 used. The absorber element 10 has in the embodiment of 1a and 1b a substantially wedge-shaped cross-section. The foot 9 of the absorber element 10 can be designed as a separate component, the absorber element 10 however, it can also be designed in such a way that the foot 9 in one piece on the absorber element 10 is molded.

The absorber element 10 engages in an absorber block when the window is closed 11th on the frame 1 a. The absorber block 11th can one to the absorber element 10 geometrically corresponding incision, here wedge-shaped in cross section 12th exhibit. The absorber block 11th can in a housing 11a be used, the side-so in the room II facing side of the frame profile 100 in the frame 1 or in the frame profile 100 is used. The frame profile 100 or the metal shell facing room II 103 shows a geometrically corresponding section 101 on.

The absorber element 10 and the absorber block 11th can be made from a sound wave absorbing material, particularly preferably from a foamed plastic such as polyurethane foam.

It is provided that at least in the open state of the window a ventilation duct 13th (formed in dashed lines) is formed, which has a first ventilation duct opening 14th and a second ventilation duct opening 15th having. It is preferably provided that the ventilation duct openings 14th and 15th open into (surrounding) room I and (interior) room II.

The ventilation duct 13th has at least one change in direction of an imaginary flow line (see reference symbols 13th ) between 45 ° and 90 ° - in the example of the 1b two such changes of direction, so an S-shape. The ventilation duct 13th is also designed to allow air to pass through the ventilation duct 13th flows through, due to the geometric design and the dimensions of the absorber element 10 and the absorber block 11th to which at least one change of direction is forced.

It can further advantageously be provided that the absorber element 10 and the absorber block 11th is designed in the manner of a ventilation cassette, which is inserted into the cutout 101 of the frame profile 100 is used. There can also be several of these ventilation cassettes per frame profile 100 or be provided on several sides of the frame (not shown).

The absorber block 11th and the absorber element 10 can in this way only once in one or in several of the profiles 100 of the surrounding window frame 1 be trained. Alternatively, the absorber block 11th and the absorber element 10 preferably in the form of ventilation cassettes, also in one or more profiles 100 of the frame 1 be trained several times.

It should be noted at this point that the arrangement can also be “completely” reversed, in which case the absorber element is then 10 or the ventilation cassette in the casement 2 lies. The arrangement of the center seal 105 can then from the sash 2 to the frame 1 or vice versa.

In the ventilation position of the 1b the sash became relative to the frame 1 moved into an open position, in particular pivoted and / or displaced. This open position is a ventilation position. It can - but this is not mandatory - correspond to the maximum attainable position when tilting or rotating or the like. But it can also be a kind of intermediate position. This is preferably chosen so that a labyrinth-like deflection of the air flow parallel to the surface element 3 aligned rebate section F _III is retained, so that the absorber element 10 something else in the incision 12th of the absorber block 11th intervenes.

The gap S _I , S _II and S _III are open in this position because the stop seals 5 and 7th as well as the center seal 105 no longer in contact with the frame 1 or casement 2 are located. This creates the frame rebate spaces F _I and F _II that is perpendicular to the plane of the surface element 3 are arranged, as well as the rebate section F _III , which is parallel to the plane of the surface element 3 is arranged, no longer sealed and form at least part of the ventilation duct 13th the end.

At the perpendicular to the 1a running sides of the window frame also form corresponding gaps in the ventilation position S _I , S _II and S _III which, however, do not have a constant width when swiveled open. Nevertheless, in addition to improving the ventilation effect, ventilation ducts can also be found on these sides 13th according to the type of 1a until 5b also be trained.

For example, if room I is the surrounding area of a building and room II is an interior II of the building, air can pass through the opened gap S _I , the open ventilation duct 13th , the first frame rebate section F _I , F _II and the second rebate space section substantially perpendicular thereto F _III as well as the gap S _II and S _III flow into the (interior) room I. Sound is generated in particular through directional deflection (s) in the ventilation duct 13th advantageously insulated.

It should therefore preferably be inside the ventilation duct 13th the air flowing through preferably have to change direction once or several times. This has a beneficial effect on sound insulation.

The ventilation duct 13th opens, for example, it can also open if the sash is moved to an open position in another way, eg with a tilted window or a tilted sash frame 2 like this in 1b is shown, or alternatively by rotating around a vertical axis of rotation (rotating window), by folding or pivoting (upper or lower horizontal axis of rotation of the sash) or sliding (e.g. parallel opening).

In order to avoid repetition, only deviations, changes and / or additions to the exemplary embodiment are described below 1a and 1b described.

Deviating from the variant according to 1a and 1b has the absorber element 10 according to the variant 2a and 2 B a wave-like structure on the flanks of its wedge-shaped cross-section 16 on. The absorber block has accordingly 11th in his cut 12th a wave-like structure that corresponds geometrically to this 17th on (see 2a and 2 B) . When the window is open (see 2 B) results in a ventilation duct 13th , which has two changes of direction -also an S-shape. This advantageously has a sound wave-absorbing effect. Because of the wave-like structures 16 , 17th Another advantageous sound-wave-absorbing effect results from the absorber element 10 and the absorber block 11th .

The variant according to 3a and 3b has an absorber element 10 on, which has a rectangular envelope geometry in cross section. The absorber element can on its flanks 10 a wave-like structure arranged symmetrically to an imaginary center plane of the cross section 18th exhibit. The absorber element 10 can then in each case at wave troughs of this wave-like structure 18th one breakthrough each 19th exhibit.

The absorber element 10 can optionally also at its free end 20th optionally a seal 21 exhibit. The seal 21 seals when the window is open (see 3b) the rebate section F _III against the incision 12th off so that the the ventilation duct 13th air flowing through the respective breakthrough 19th must flow. The wave-like structure 18th of the absorber element 10 has an advantageous sound-absorbing effect. The absorber block 11th points in its incision 12th a wave-like structure that corresponds geometrically to this 22nd on (see 3a and 3b) . When the window is open (see 3b) results in a ventilation duct 13th , which here has a change of direction -also an L-shape. This also has the advantageous effect of absorbing sound waves.
