Description

The present invention relates to a window assembly.

The pamphlet DE 34 22 151 A1 relates to a soundproof window with a frame made of hollow plastic profile rods. It is provided that the window frame has air passage openings on its outside as well as on its inside, which open into the interior of the window frame. The openings on the outside are offset by a considerable amount relative to the openings on the inside, the cross-section of the cavity of the window frame at least in its area connecting the outer and inner openings being partially filled with sound-absorbing material, for example such a plastic foam.

The pamphlet DE 28 06 574 A1 relates to a window ventilation element for installation on the edge of a window opening. It is provided that there is both a supply air duct running in the longitudinal direction of the window ventilation element, communicating with the outside air and the interior via openings with a fan built into its outer end zone, and one running in the longitudinal direction of the window ventilation element, via openings with the interior and with contains the exhaust air duct communicating with the outside air, and that both supply air and exhaust air ducts have walls clad with sound-absorbing material.

The pamphlet DE 20 2014 100 066 U1 relates to a window construction with a window sash and a window frame. The window construction is characterized by a glazed porch, with a space being present between the sash and / or the window frame and the glazed porch.

The pamphlet DE 41 43 036 A1 relates to a ventilation device for rooms with a duct connecting the room to the outside area and in which a fan is arranged. The channel runs at least partially through a frame of an outer window and is provided with sound-absorbing means preventing the passage of sound vibrations from the outside to the inside. As a result, opening the window can be dispensed with in the event of noise pollution from the outside, while the room is still adequately ventilated. The construction of the ventilation device prevents sound from being transmitted from the outside to the inside via itself.

The pamphlet DE 77 29 730 U relates to a window consisting of a sash frame and a frame and two glass panes arranged parallel to one another at a distance with an air duct for the discharge of room air to the outside. It is provided that the upper horizontal leg of the window frame has a first channel extending from the space between the two glass panes upwards and then in the direction of the room and that the space between the two glass panes communicates with a second channel located below the window sash frame, which extends horizontally essentially from one lateral end to the other end of the window, there at an angle of 180 degrees in the opposite direction, runs horizontally to near the first lateral end of the window and opens out there.

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 soundproof windows.

However, since the trend is emerging to move to residential areas that are subject to very high levels of noise pollution (e.g. in the immediate vicinity of ports 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 by tilting the window is also not possible.

This is where the present invention comes in and has the task of proposing an improved window arrangement, in particular proposing a window arrangement with which ventilation and soundproofing can be made possible at the same time or can be improved over existing systems.

According to the invention, this object is achieved by a window arrangement having the features of claim 1. In particular, it is provided here that the window attachment is equipped with a ventilation duct, the ventilation duct being formed at least in sections, preferably completely, from an acoustic absorber element arrangement. The window attachment can be attached like a window in front of the window to be opened. At When the window is closed, a gap is formed between the window and the window attachment, into which the ventilation duct opens.

If the window is now opened, air from the environment can flow through the ventilation duct into the interior space behind the window and of course vice versa. However, since the sound has to pass through the ventilation duct, there is a reduction in sound transmission, in particular sound absorption. As a result, a window arrangement can be provided with which ventilation and soundproofing can be made equally possible or can be improved over existing systems.

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

In an advantageous embodiment of the invention it can be provided that the window attachment frame is adapted to the window frame with regard to its dimensions, so that it can be attached, preferably screwed, as an attachment in front of the window frame. It is advantageous if the front window frame ends, for example, flush with the inner edge of the window frame, so that an almost seamless transition can result in this area.

In a further advantageous embodiment of the invention, it can be provided that the window is equipped with a parallel parking device, a turn, tilt and / or turn-tilt device. The aforementioned devices are suitable as an advantageous opening and closing mechanism for the window in order to move the window back and forth between a closed position and a ventilation position.

According to the invention it is provided that an intermediate space is formed between the window and the window attachment, the ventilation duct having a first opening facing the ambient air and a second opening facing the intermediate space. The intermediate space that forms when the window or window sash is closed is connected to the ambient air on the outside of the window arrangement via the ventilation duct. As soon as the window or the window sash is opened, air from the environment can flow through the ventilation duct into the interior of the building behind the window and of course vice versa. However, since the sound has to pass through the ventilation duct with the acoustic absorber element arrangement, a reduction in sound transmission, in particular sound absorption, takes place here.

In a further advantageous embodiment of the invention it can be provided that the ventilation duct has at least one deflection, in particular that the ventilation duct has at least two sections which differ in terms of their alignment with respect to the frame plane, in particular that the ventilation duct has a first, third and fifth Has section which are aligned essentially parallel, preferably parallel, to the frame plane and a second and fourth section, which are aligned substantially perpendicular, preferably perpendicular, to the frame plane, the sections being attached between the openings and, the first section opens into the first opening and the fifth section opens into the second opening. The at least one deflection can ensure that the sound is exposed to as many reflections as possible on the way from the outside to the inside. With every reflection, sound energy is converted into heat. Therefore, the largest possible selection of reflections helps to ensure that as much sound energy as possible is absorbed.

In a further advantageous embodiment of the invention it can be provided that the absorber element arrangement is formed from open-pore materials with high flow resistance, such as mineral wool and / or stone wool.

Insofar as the terms “outside” and “inside” 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 arrangement according to the invention essentially comprises a window and a window attachment.

By the window 1 it can be a commercially available window, essentially comprising a frame 11 and a casement 12 . The casement takes on a surface element, usually an insulating glass pane. But single glazing is also conceivable. The sash elements or frame elements usually comprise aluminum or plastic profiles which are connected to one another by means of insulating profiles, usually made of plastic. But other, basically arbitrary, structures of the individual window profiles are also conceivable. Other suitable materials, such as wood, are also conceivable.

The casement 12 can opposite the frame 11 tilted, rotated, parked and / or moved in parallel, so ultimately the window can be opened. For this purpose, the window is equipped with what is known as a parallel parking device, turn, tilt and / or turn-tilt device (not shown). Ultimately, the window or the window sash can be transferred from a closed position to an open position and vice versa. Other types of movement between the casement and the frame are also conceivable, which ultimately allow the window to be opened for ventilation purposes.

The structure of the window is sufficiently known to the person skilled in the art and does not need to be further elaborated here.

The window attachment 2 essentially comprises a window cladding frame 21st and a surface element 22, usually also an insulating glazing.

The window cladding frame 21st usually comprises four frame elements that are joined together to form a rectangular frame. The frame element as such can also be made in several parts, that is to say made up of several profiles, preferably hollow profiles. The surface element 22 is from the window attachment frame 21st recorded. Aluminum is preferably used as the material for the frame elements. However, other suitable materials, such as plastic, are also conceivable.

The window cladding frame 21st as such is in terms of its dimensions on the frame 11 adapted so that it can be attached, preferably screwed, in front of the frame as an attachment. In the ideal case is the window attachment frame 21st flush with the inner edge of the window frame 11 .

The window cladding frame 21st is according to the invention with a ventilation duct 24 equipped, which at least in sections, preferably completely, from an acoustic absorber element arrangement 23 is formed. Further details on this result from a closer examination of the window arrangement according to the invention.

As shown in the figures, the window attachment is 2 in front of the window 1 installed, in particular the window attachment frame 21st as an attachment in front of the frame 11 assembled. With the window closed 1 or casement 12 it can be seen that there is a space 3 between the window attachment 2 , in particular the surface element 22 of the window attachment, and the window 1 , especially the casement 12 or its surface element 121 results.

The window attachment is in a common mounting position 2 on the outside of the window 1 mounted or forms the window attachment 2 the outside of the window assembly.

The ventilation duct 24 has a first opening which is accessible from the outside for ambient air 241 and a second opening facing the intermediate space 3 242 on. The ventilation duct 24 accordingly opens into the space 3. In other words, the ventilation duct 24 establishes a connection between the environment and the space 3.

As can be seen in the pictures, the ventilation duct 24 over long distances through the acoustic absorber element arrangement 23 , in particular formed by individual acoustic absorber elements.

The acoustic absorber elements can, for example, be used as insert elements in the window attachment frame 21st be designed and preferably by means of screws with the window attachment frame 21st or be connected to the frame element. The absorber element arrangement can, however, also be designed as a single monolithic element.

In the acoustic absorber elements or the acoustic absorber element arrangement, preferably open-pore materials with high flow resistance, such as mineral wool and / or rock wool, are used.

The absorber elements do not have to consist entirely of these materials. Support materials can also be used. However, the areas facing the ventilation duct should be made of acoustically effective absorber materials.

The ventilation duct preferably has 24 at least one diversion. The ventilation duct can do this 24 have at least two sections that differ in terms of their alignment with respect to the frame plane B. distinguish. The ventilation duct essentially has a first, third and fifth section 243 , 245 , 247 which is essentially parallel, preferably parallel, to the frame plane B. are aligned and have a second and fourth section 244 , 246 which are aligned essentially perpendicular, preferably perpendicular, to the frame plane. The sections are between the openings 241 and 242 attached, the first section 243 into the first opening 241 and the fifth section 247 into the second opening 242 flows out. The sections as such are arranged one behind the other in the order in which they are counted. The result is a ventilation duct 24 with several diversions. The ventilation duct could also be addressed as a ventilation duct in the manner of a labyrinth.

The result is a window arrangement that combines positive properties in terms of ventilation and noise protection. With the window open 1 or casement 12 finds ventilation via the ventilation duct 24 instead of. The casement 12 is, as it were, opened to the space 3 existing when the window is closed. Air can be drawn from the environment through the ventilation duct 24 in the interior behind the window 1 stream and of course vice versa. Since the sound, however, the ventilation duct 24 has to happen, there is a reduction in sound transmission.

The surface element 22 of the window attachment 2 and also the frame 21st of the window attachment also have a sound-absorbing effect, so that even due to the aforementioned components, ambient noise cannot or only significantly reduced into the interior.

A ventilation grille can be used to protect against insects or larger dust particles 25th be provided. The ventilation grille 25th can in the window attachment 2 , preferably in front of the ventilation duct 24 installed.

It is also conceivable that means are provided which are set up for the ventilation cross section of the ventilation duct 24 to be reduced in sections, for example by using a ventilation duct 24 partially closing element, for example an absorber element, as for example in 4th is shown. It can be seen that an absorber element is used in a region of the third section of the ventilation duct, which is identified by the reference symbol 245 ' is marked. The third section, however 245 free in the lower area. This measure essentially serves to further improve the sound insulation.

It can also be provided that the ventilation duct 24 has different cross-sections in the direction of flow. This measure can also contribute to the reduction of sound transmission.
