Definitions
- 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 DE 102016 115422.
- the generic construction has a relatively complicated structure and should therefore in this regard and according to variants also in With regard to various other properties, it can be further optimized.
- the problem is that the ventilation duct formed in the frame can only be cleaned and maintained with great difficulty.
- 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 object by the subject matter of claim 1 and claim 4 and also provides an advantageous ventilation cassette for such a window. It also creates an advantageous process.
- a window is created which has at least the following features: a frame composed of several frame profiles, a sash frame composed of several frame profiles, which preferably has at least one surface element and at least between a closed position and a ventilation position movable Lich relative to the frame is, wherein a circumferential frame rebate space is formed between the frame profiles of the window frame and the frame profiles of the sash, at least one in at least one of the frame profiles of the window frame or in at least one of the frame profiles of the sash formed ventilation duct, which has a first ventilation duct opening and a second ventilation duct opening , wherein the casement and the frame are designed to be in their Interaction in the first closed position to close at least one of the ventilation duct openings, and in the second position - a ventilation position - to release both ventilation duct openings of the at least one ventilation duct characterized in that the one or more ventilation ducts is / are each formed in at least one ventilation cassette or several ventilation cassettes which are / are used in the frame
- the formation of the ventilation duct is significantly simplified because it does not have to be laboriously formed directly in the hollow chamber profiles. Rather, it is sufficient to provide or form a recess there and then insert the preassembled ventilation cassette into the recess, e.g. to snap it into place or clamp it. This makes it simple and straightforward to form a ventilation duct in a ventilation window.
- the respective ventilation cassette can be inserted in a simple manner and preferably outwardly in the closed position, invisibly into a recess of the respective frame profile or of the respective sash profile facing the frame rebate space.
- the ventilation cassette has an insert which is inserted into an in particular trough-like base element of the ventilation cassette.
- the use of the ventilation cassette built into the window is then particularly preferably exchangeable, which simplifies the maintenance of the ventilation window.
- the invention then creates a window according to claim 4 that has the features of the ventilation window of claim 1 in the preamble and the following combination of features in the characteristic: the one or more ventilation ducts is / are each formed in at least one ventilation cassette or several ventilation cassettes / which is / are inserted into the window frame or the casement or in the respective window frame profile or the respective casement profile, the respective ventilation cassette having an insert which is inserted into a trough-like base element of the ventilation cassette, the use of the in the The ventilation cassette built into the window can be changed without having to remove the basic element. In this way, only the insert is changed in the event of maintenance, which is particularly straightforward.
- 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 to be circumferential or not to be configured 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 therefore also form part of a facade construction.
- the ventilation cassette has a cover for covering the base element and, if applicable, the insert, and that the cover is detachably fastened to the base element with a detachable fastening means.
- a sealing groove is formed on the ventilation cassette, in particular on the cover.
- the respective insert can consist of one or more materials.
- the insert can thus have a filter material. It can also be provided that the insert has a film, in particular a heavy film.
- the sound insulation properties can be optimized in this way. It can be provided that the respective ventilation cassette is inserted into a respective recess of the respective frame profile or of the respective sash profile facing the frame rebate space. Because installation and maintenance are particularly easy to carry out here.
- the respective ventilation cassettes are inserted into recesses of the respective frame profile or of the respective sash profile facing the frame rebate space. In this way, the respective ventilation cassette can have compact dimensions and maintenance remains simple.
- the ventilation cassette (s) are only provided in the upper side of the window frame when installed.
- the invention also provides a ventilation cassette for a window according to one of the preceding claims, in which one or more ventilation ducts is / are, the ventilation cassette having an insert which is inserted into a base element of the ventilation cassette, the insert being the The ventilation cassette built into the window can be changed without having to remove the basic element. With this ventilation cassette, the maintenance of a ventilation window is particularly easy.
- the respective ventilation cassette has the ventilation duct openings and that these are aligned with the frame rebate space. It can be particularly advantageously provided that the ventilation duct openings in the closed state lie completely in the frame rebate space between the stop seals. This does not change the external appearance of the window. The preferred design remains.
- the ventilation cassettes can be changed very easily in this way. This is required roughly annually in order to meet the requirements for purity (dust, insects, etc.). No specialist is required to replace them.
- the center seal is arranged on the ventilation cassette, in particular on the groove of the ventilation cassette. It can also be provided that the sash, when it is moved from the closed position into the ventilation position, can be moved at least at one point by 50 to 80 mm relative to the frame.
- the air exchange at 2 PA can be more than 12 m 3 / h (preferably> 14), at 10 PA> 25 m 3 / h (preferably> 28) (air pressure difference between inside and outside, e.g. caused by Wind pressure or static pressure difference).
- PA Paddle air pressure
- PA> 25 m 3 / h preferably> 28
- air pressure difference between inside and outside e.g. caused by Wind pressure or static pressure difference.
- whoever arranged in the ventilation cassette synthetic microfibers that are able to filter pollen. This is of particular benefit to allergy sufferers.
- this cassette can simply be cleaned and / or changed after opening the window, for example after one or more years.
- the ventilation cassette can be fixed in the most varied of ways on the frame, so clamped or preferably with a loading fastening means such as at least one screw. It is also conceivable to change a filter material in the ventilation cassette if the ventilation cassette is provided with such a material.
- the ventilation cassette can have a further or more of the further features directed to the ventilation cassette in the preceding claims relating to the ventilation window.
- a window frame profile is provided, that a recess facing the frame rebate is then formed in the respective window frame profile, in which a ventilation duct is to be formed is and that a ventilation cassette is inserted into this recess facing the frame rebate space of the respective frame profile or the respective sash profile, which has a changeable insert.
- At least one sealing plane is formed between the frame and the casement in the region of the frame rebate space in the open state, which is at least a seal is formed which rests at least in the ventilation position with a position sliding section on the frame or on the casement.
- the contact sliding section in the ventilation position rests against a contact sliding strip of the sash frame or the window frame, which is formed on the wing frame or the window frame, in particular attached and with a free end into the rebate space protrudes.
- the contact slide strip provides a component that is fitted to the one or more seals that are in contact with it.
- the shape, surface and material of the contact sliding strip can be matched to the one or more seals, so that an optimal sliding and / or rolling process is achieved. This reduces the operating forces at the window to a minimum.
- the contact sliding strip is intended exclusively for contact with the (sliding) seal arranged on the opposite frame and does not take on any other static function of the sash frame. It is therefore not an integral strip of the casement or frame that makes a significant contribution to its statics or influences it, as is the case with an insulating strip that connects two metal shells. It is true that the system sliding strip influences the closing and opening forces when the sash is closed and opened, since a corresponding sliding seal preferably rests against it and can slide if necessary during the opening and closing movement. But this is also one of its tasks and one of its advantages, to which it can be specially adapted, unlike strips or profiles, which primarily serve other purposes.
- the contact slide strip extends in sections, in particular spaced essentially parallel, to the sash frame, in particular in such a way that the contact slide strip extends in sections parallel to an insulating web of the sash frame, which stretches two metal shells of the sash connects together and forms a portion of the rebate space.
- the seal which comes to rest in the open or ventilation position and possibly also in the closed position of the window, is used as a seal Center seal is formed.
- This central seal can in turn be advantageously designed to divide the frame rebate space into at least two frame rebate space sections so that air in the ventilation position between the two frame rebate space sections can essentially only be exchanged through the ventilation duct, the center seal having a seal base and at least one on the sealing base pivotally attached sealing section, which is articulated to the sealing base, the sealing section in any case in the area or areas in which a respective ventilation duct is formed in the ventilation position at its free end with the contact sliding section on the contact sliding bar is applied. It can also be seen in front of two or more such center seals.
- At least two or at least three sealing levels are formed between the frame and the sash in the area of the frame rebate space all around in the closed state.
- One or two of the sealing planes can also be formed by one or more stop seals between the frame and the casement. These sealing levels only exist when the sash is closed. When the sash is opened, the window is set to its ventilation position so that air can be exchanged through these open sealing levels and the ventilation duct between the rooms that the window is in when it is installed, i.e. usually between inside and outside.
- the center seal is attached to the frame and is in particular in the ventilation position in contact with the sash.
- the center seal is attached to the frame and the contact slide strip is attached to the casement. It can be expediently provided that the contact sliding strip is mounted laterally on and / or in a corner area of the respective corresponding sash profile. It can be provided that the contact sliding strip is fixed with one of its ends on a metal shell of the sash profile on the side of an insulating web of the sash profile. Because in this otherwise usually unused area of the wing frame, the means such as a groove or the like to be provided for fixing the system sealing strip can be formed and accommodated. According to a further option, it can advantageously be provided that the at least one center seal rests on the contact slide strip both in the ventilation state and in the closed state.
- one of the two center seals is expediently designed in such a way and the other in such a way that it only rests on the contact slide bar in the closed position, but is spaced from it in the ventilation position, so that access to the ventilation duct is released .
- the one or at least one of the center seals is designed as a lip seal with one or more sealing lips, which are each designed to be flexible. Because in this way the flexible sealing lips can be used to rest on the contact slide strip, which accordingly does not or hardly hinder the opening movement or closing movement of the wing.
- the frame and casement are each formed from profiles that have one or more metal shells and an insulating layer on one metal shell or between two metal shells.
- Other structures such as casement frames and / or blind frames with three metal shells and two insulating web zones between the metal shells are also conceivable.
- the reinforcement insert can be designed as a metal profile, for example as a tube. It is advantageous if steel pipes, for example square pipes, are simply inserted and screwed into the PVC profiles as reinforcement inserts. It can also be provided that a reinforcement reinforcement, for example made of metal in coextrusion with the multi-chamber hollow profile, is made of plastic.
- seals are used as the stop seals and / or the center seal, which are inserted into retaining grooves and held in them.
- Such seals are relatively inexpensive and, above all, easy to assemble. They can be laid all around without having to be cut in the corners. Due to the arrangement in retaining grooves, the seals can be easily replaced.
- the seals can also be welded together.
- the relatively small opening width results in the prior art mentioned at the beginning by the closure means, the insulating web. This has only a limited length.
- the sliding sealing lip closes the gap between the frame and the sash up to the outer profile edge of the sash profile. This results in a larger opening width ("W").
- W opening width
- B profile width
- 50 to 80 mm are preferred.
- the geometry of the sliding seal, in particular the length of the sealing lip, is also decisive. Overall, therefore, even greater widths are possible. A width of 55 to 65 mm is particularly preferred.
- the central seal has a seal base and a sealing section that is pivotably attached to the seal base.
- This is preferably designed as a pivotable sealing lip.
- the sealing section - in particular the sealing lip - can be connected to the seal base in an articulated manner.

- the frame profiles can be designed as plastic profiles. But they can also be designed as so-called composite profiles (Fig. 3). Then they usually consist of one or more metal profiles - also referred to synonymously here as metal shells - and one or more insulating bars.
- a construction is preferred in which two metal profile levels are connected to one another via an insulating level, which is usually made of plastic. But there are also other, further designs conceivable, so in particular designs with a metal profile level and egg ner insulating profile level made of plastic and designs with three metal profile levels and two insulating profile levels.
- This frame rebate space F essentially extends between the outer circumference of the casement 2 and the inner circumference of the window frame 1.
- the respective window of Fig. 1 or 3 is used to be able to close and open a room opening of a building (not shown here), with a room I (e.g. an area surrounding a building) from a room II (e.g. an interior of the building) is separated.
- a room I e.g. an area surrounding a building

- the means and configurations discussed below can each preferably be configured circumferentially or in sections on the 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 hinge axis) or on several of the corresponding frame profiles of the casement 2 and the window frame 1.
- Fig. 1 b running Be th of the window frame in the ventilation position also corresponding gaps are formed, but which do not have a constant width when opening a pivot.
- ventilation ducts 8 can also be formed on these sides.
- the sash frame 2 can - preferably to one side or to an adjoining the room II - have a contact web 4 with which it rests in the closed position on the frame 1 directly or via a stop seal 5 attached to the sash frame 2.

- the center seal 18 may have a seal base 20 with a sealing foot 21 which is inserted into the groove.
- the seal 18 can also have a sealing section 22 pivotally attached to the seal base 20. This can be designed as a single sealing lip (Fig. 1a and 1b) or as a combination of two or more sealing lips (Fig. 2a and b).
- the sealing section 22 can in particular have a sealing lip which is designed to be curved in itself and / or again has a hinge 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.
- sealing section 22 can be pivoted relative to the sealing base 21 and that it is so long that it can be in contact with the sash frame 2. There it is preferably on with an end section. This end section can be arcuate.
- the sealing portion 22 can alswei sen as an end portion of a plant sliding portion 23, which can slide well on the corresponding frame profile, here the sash profile, with relative movements between the frame 1 and the sash frame 2. This results in a harmonious, slight opening movement that is not significantly hindered by the adjacent sealing surface.
- the contact sliding section 23 is preferably provided on the center seal where a ventilation duct 8 is also provided in the respective frame profile. This can be on one side of the window frame 1 or sash frame 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 is located.
- the contact sliding section 23 can be dispensed with here.
- the sealing section 22 is preferably so long that it initially remains in contact with the sash frame 2 over a certain opening angle when the sash is opened or is in contact with the sash frame 2 in a ventilation position to be explained below, or comes, so that it divides the frame rebate space F in the ventilation position into two areas, between which an exchange of air takes place essentially only via the ventilation duct 8.
- the center seal 18 thus divides the frame rebate space F into a first and a second area Fl, Fll (corresponding to the orientation to the spaces I and II), between which an exchange of air is only possible via the ventilation duct 8 formed in the frame 1.
- the center seal is attached to the sash frame 2 and extends as far as the frame 1.
- the sealing section 22 should preferably be so long that it then remains in contact with the frame 1 when the sash is opened, initially over a certain opening angle, or is in contact with the frame 1 in a ventilation position to be explained comes, so that it divides the frame rebate space F in the ventilation position into two areas, between which an exchange of air takes place essentially only via the ventilation duct 8.

- the order of the center seal 18 can then be done from the casement 2 to the frame 1 or vice versa.
- the ventilation position L in FIG. 1b the sash has been moved into an open position relative to the frame 1, in particular pivoted and / or displaced.
- This open position is a ventilation position. You can - but this is not compulsory - the maximum achievable position when tilting or turning or the like. Ent speak.
- the column Sl and Sil are open in this position, since the limit seals 5 and 7 are no longer in contact with the frame 1 or sash 2 are the.
- the center seal 18 is still in contact with the sash frame 2.
- the wing gel is still partially within the scope defined by the frame 2. Since the center seal 18 blocks the direct transition between the spaces Fl and Fll, an exchange of air between these spaces Fl and Fll and thus also an exchange of air between the spaces I and II can only take place through the ventilation duct. This makes for a very advantageous combination from a ventilation and a sound insulation effect.
- air can flow into interior space I through gap S1, the frame rebate space section Fl, ventilation duct 8, frame rebate space section Fll and gap Sil.
- the sound is advantageously insulated, 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 the 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.
- both ventilation duct openings 9, 10 are oriented towards the frame rebate space F.
- At least one wall 19 can be formed inside the ventilation cassette 14 which divides the ventilation cassette interior into sections. This wall 19 may have at least one passage 19a. One of the ventilation duct openings 9, 10 is then located in one of the sections.
- the ventilation duct 8 runs in an approximately U-shape within the ventilation cassette 14 (or even without a ventilation cassette). 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, there it extends through the passage 19a of the wall 19 and again runs approximately parallel to the surface element up to the ventilation duct opening 10 In this way, the direction of 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 ventilation cassette 15 can also be provided in the exemplary embodiment in FIG. 3 (see, for example, FIGS. 3b) to d), will be explained in more detail below).
- it can then be inserted into a chamber, in particular a milled cutout in the blind frame, in a manner analogous to FIG. 1, and / or it can completely replace one or more otherwise provided insulating webs in its area.
- the ventilation duct can, however, also be formed directly as a duct-like milled recess in the frame or it can be delimited by duct-like elements which are used in these milled-out conditions.
- a contact slide strip 24 is arranged on the casement 2 or on its casement profile 2 ''.
- the center seal 18 can then rest against this in the ventilation position L.
- the contact slide strip 24 can alternatively also be designed in such a way that the center seal 18 also rests against the contact slide strip in the closed position.
- the contact slide strip 24 is provided relatively far from Lich and / or in a corner area of the respective casement profile 2 '.
- This corner area is preferably that corner area which is closest to the corresponding frame profile V in the opening and ventilation position.
- the contact slide strip can lie laterally outside an area that is defined by the inner and outer edge planes of the insulating glass pane. This is the case with FIG. 1, for example. In Fig. 3 this is also the case, only is here the contact slide strip is preferably attached to one of the metal profiles, in particular to one of the aluminum profiles of this construction.
- the contact slide strip 24 can also extend in the rebate space to such an extent that the center seal 18 also rests against it in the closed state.
- the system slide bar 24 can be made of metal or some other material such as plastic. They also have at least one hollow chamber themselves.
- the contact slide strip 24 can also advantageously be designed as an extension strip which is fixed with a fastening, for example a tongue and groove connection, on the respective wing frame profile 2.
- the frame profiles in particular the outer walls to the rooms I and II are formed according to the embodiment of FIG. 1 from a plastic material, preferably PVC. They are preferably made entirely of plastic - possibly with the exception of internal reinforcement profiles or reinforcement reinforcements. They can be made in one piece, especially if they are made of plastic.
- the outer walls of the hollow chamber profiles made of plastic 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.
- further reinforcement reinforcements 10, 11 made of metal are optionally arranged in the hollow chambers for static reinforcement and further subdivide them.
- stop seals (inside / outside) 5, 7 and the center seal 18 are formed circumferentially, that is to say on four sides of the Frame run, while the sealing portion is not provided on all sides of the frame mens.
- the contact sliding section 23 closes the frame rebate space or gap between the frame and the sash up to the outer profile edge of the sash frame 2.
- a larger opening width (,, W ‘) is achieved compared to the prior art.
- W the profile width
- 50 to 80 mm are preferably achieved.
- 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 achieved in the ventilation position. A width of 55 to 65 mm is particularly preferred.
- the formula for a maximum opening width for sound-insulated ventilation can be assumed: Wmax.
- a significantly larger number of hollow chambers compared to an aluminum composite structure has an advantageous effect in terms of sound insulation.
- the friction of the sliding seal on the sash frame can be reduced to a minimum.
- the sliding seal preferably has a roughened surface structure on the sliding side.
- the system sliding strip is preferably characterized by a sliding coating.
- the surface structure can of course 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 reasons of sound insulation. 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.
- a further sealing lip 25 is to be formed on the center seal 18 on the sealing base 20, which in the closed state rests on the sash frame 2, so that between the Blendrah men and the sash frame even in sections four sealing levels in the frame rebate space are advantageously formed.
- a particularly advantageous feature of the contact slide strip 24 is that a component is provided which is adapted to the one or more corresponding seal (s) on which it rests.
- the contact sliding strip 24 can be placed on the seals in terms of shape, surface and material run, so that an optimal sliding and / or Unrolling is achieved. As a result, the operating forces at the window are reduced to a minimum.
- the seals “slide / roll” on the contact slide bar 24 until they no longer have any contact with the frame profile.
- Isolation bars are usually very smooth, so that seals tend to adhere to them.
- a metal in particular aluminum, is preferably used as the material for the contact slide strips 24.
- the rough surface can be achieved by deep-pore anodizing. Special lacquers that form a slightly rough surface after drying can also be used to create a slightly rough surface.
- plastics can also be applied or overmolded, which are given surfaces that are well suited for the contact strip,
- Overmoulding can be implemented, for example, in an extrusion process. It is important that the system sliding strip can be optimally adjusted to the seals. This is not possible with system insulating bars.
- the function of the ventilation window is given until the seal lifts off the insulating bar. This point limits the opening width.
- the abutment sliding strip according to the invention maintains contact with the seal significantly longer than was the case in the prior art, as a result of which a larger opening width can be achieved.
- the contact slide strip extends to the edge of the frame profile and thus enables a larger opening width.
- the system-slide bar 24 is connected to a fold-facing side of the frame profile to which it is to be attached.
- connection options such as screws, rivets, clips, gluing, etc ..
- Preference is given to attaching the contact slide strip to the rebate side of the sash profile 102 close to an edge, in particular to the edge facing the interior or exterior is because in this way a relatively large opening in the ventilation position can be achieved in a simple manner.
- FIG. 3 shows in a) and in b) to e) in each case a section through two different aluminum composite profile constructions consisting of a frame profile 101 and a sash profile 102.
- the The outer edge of the sash profile, to which the contact sliding strip is to be attached is thus formed by an outer aluminum profile shell.
- the frame profile 101 can - as shown in Figure 3a) to e) - have a first metal shell 101a and a second metal shell 101b in this variant. These two metal shells 101a and 101b can be connected to one another via an insulating web 101c (or several insulating webs).
- the sash profile 102 can also have a first metal shell 102a and a second metal shell 102b. These two metal shells 102a and 102b are connected to one another via an insulating web 102c (or several insulating webs).
- the first metal shells 101a, 102a can be oriented toward an outside I of a building and the second metal shells can be oriented toward an inside II of a building.
- An insulating glass pane 103 is inserted into the casement.
- a center seal 104 and a sliding seal 105 are arranged. They can be attached to the frame.
- the sliding seal 105 functionally also forms a kind of center seal and the center seal 104 a kind of system seal, the latter lifting off the sash when it is opened, which is not the case with the center and system seal and also with the sliding seal 105.
- a variant of a contact slide strip 124 is provided in the fold F.
- This system sliding strip 124 is attached to the sash profile 102 in the area of the outside I.
- it has a fastening end 124 a (which can also be called a fastening base 124 a or fastening foot).
- the fastening foot can be designed as a projection which engages in the groove 102d. As an alternative or in addition, it can also be clamped and / or latched there.
- the fastening base 124a can thus engage in the groove 102d of the sash profile, in particular in the first metal shell 102a (preferably towards the outside I). Additionally and / or alternatively, the fastening end 124a can be fastened there with a fastening means, for example screwed tightly with a screw.
- the contact slide strip 124 protrudes somewhat into the fold F in the direction of the frame profile 101 and then extends at a distance from the insulating web 102c of the sash profile next to it in the direction of the second metal shell 102b of the sash profile, but does not touch it.
- the cable receiving groove can be formed on the insulating web 102 c) of the sash profile 102.
- the cable 135 is held well in the cable receiving groove 134 and protected against damage to the fold by the contact slide strip 124.
- the contact slide strip also forms a folded cable strip here, which significantly simplifies the laying of a cable on the sash frame. In the case of an upside-down construction with a contact sliding strip on the frame, the laying of a cable on the frame is simplified accordingly (not shown).
- the two seals 104 and 105 - i.e. here the center seal 104 and the sliding seal 105 - both lie against the contact sliding strip 124.
- the contact slide bar 124 protrudes in the fold over the insulating web of the wing frame, but is not thermally advantageous on the insulating web, so that a gap X can even form in sections towards the insulating web.
- the contact slide strip 24 can be resiliently deformed in order to evade the forces acting, in particular when the sash is opened and closed. This advantageously reduces the operating forces when opening and closing the sash.
- the contact slide strip 124 can, in preferred configurations, protrude up to approximately the middle of the insulating web 102c. But it can also be designed longer. It is preferably designed in such a way that in the open position of the wing at least one of the two seals 104, 105, in particular the sliding seal 105, is in contact with it (similar or analogous to FIG. 1b).
- Ventilation windows are described below, in each of which one or more ventilation cassettes 14 are provided.
- the windows can per se be constructed in the manner of FIGS. 1, 2 or 3a or 3b) to e). However, they can also have a structure that differs from this in terms of details.
- the following description relates in particular to preferred features and variants that relate to the ventilation cassettes 14 or the structure of the windows, insofar as this relates to the integration of the ventilation cassettes 14 into the structure of the respective ventilation window.
- the features of the ventilation cassettes 14 described below can be implemented as advantageous options on the windows formed in FIGS. 1 to 3 or on differently constructed windows. These features can also be advantageous individually and in combination, ie they can individually or together also form part of the scope of protection or can be used to create it.
- the cassette would preferably replace the ventilation duct which is only partially inserted here directly into the frame profile.
- FIG. 4 in a) and b) shows a side view and a perspective view of a further ventilation window which is provided for the installation of one (or more) ventilation cassettes, as is shown, for example, in FIG. 3.
- the respective ventilation cassette 14 in turn has a channel-like or trough-like base element 15.
- This basic element 15 is also configured like a box here.
- the base element 15 can be designed closed on a base side and on four sides and be designed to be open on a side facing the fold in the installed state.
- the respective ventilation cassette 14 - in particular on this open side - has the cover 16.
- One or more openings 16a can be provided in this cover 16. With the cover 16, the base element 14 forms a box here all around except for the openings 16 closed. Preferably, at least two of the openings 16a, 16b are seen before.
- the first opening 16a then preferably forms the first ventilation duct opening 9 and the other, second opening 9b forms the second ventilation duct opening 10.
- first openings 16a can also jointly form the first ventilation duct opening 9 and a plurality of second openings 9b can respectively form the second ventilation duct opening 10.
- first and the second ventilation duct openings can each be interrupted by first and second webs 16c, 16d.
- the base element 15 can then have a partially or completely circumferential flange 151.
- the cover 16 preferably has at least one web 161 or a bend 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 is created on the base element 15 in a simple manner.
- the flange 151 of the base element 15 can serve as an advantageous push-in limiter when the base element 15 is pushed into the recess 13 of the frame - here the window frame - so that it is easily and correctly fitted into the recess 14 during assembly (see, inter alia, Fig . 6 and 13).
- the interior of the ventilation cassette 14 may or may not be adapted to these first and second openings 16a, b.
- the interior of the ventilation cassette is not filled, but rather empty. This achieves a good ventilation effect.
- the interior of the ventilation cassette 14 is partially filled.
- the sound insulation can be further optimized in this way.
- optional measures can be taken to clean the air flow.
- An insert 141 can be used in the ventilation cassette, with which this subdivision is achieved.
- the insert 141 is particularly - but not mandatory - advantageous as an exchangeable insert.
- the insert can consist entirely or partially of a filter material 142. When the air flows through the ventilation cassette 14, particles are deposited on and in this area. In this way, the air stream is advantageously cleaned by filtering as it flows through the ventilation cassette 14 (see FIG. 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 divided into several sub-ducts 8a, 8b, 8c. In this way, the filter effect can be increased and the ventilation effect can be well controlled.
- the sound insulation can be varied in many ways in this way, in particular adapted to the external environment depending on the local conditions at the installation site. For example, on a ventilation window that is to be installed in a building opening that is on a busy street, more emphasis should be placed on good sound insulation than on a window that is oriented to a quiet side of the building.
- the insert 141 consists not only of a single material - for example the filter material 142 already mentioned - but of two or more materials.
- the further material can then be designed in such a way that it further optimizes the sound insulation in particular.
- the filter material 141 is coated on one side with a film 143, for example with a so-called heavy film.
- the cover 16 is preferably aligned with the frame rebate area F.
- the cover is detachably fastened to the ventilation cassette 14, in particular if a replaceable insert 141 is inserted into the ventilation cassette. It can also form a structural unit with the insert 141.
- the cover 16 is fastened to the ventilation cassette 14 in such a way that it can be loosened completely or almost without tools and fastened again.
- a type of quick-release lock 143 with a fastening lever 144 can be provided which is rotatable and can be latched and / or clamped under an edge of a projection 144 of the base element 15 or the like.
- the insert 141 can be changed quickly and easily.
- 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 on the cover 16.
- it has the groove 17 on its side facing the fold, in which the sealing foot 21 of the corresponding (here: central) seal 18 can be anchored.
- This groove can be aligned with a corresponding groove in the fold of the window frame. In this way, this groove in the frame is advantageously not interrupted on this side of the frame and the corresponding seal can also be securely mounted in the area of the ventilation cassette 14.
- a particularly advantageous feature of the ventilation cassette 14 with the exchangeable insert 141 is that the insert 141 of the cassette 14 is in operation and therefore used by the end user can be easily changed yourself. This change of insert is as simple as changing the filter of a vacuum cleaner. Overall, the ventilation cassette 14 itself is also easy to assemble.
- the ventilation cassette 14 can preferably be positioned invisibly in the fold, which is shown in particular in FIGS. 4a and b.
- FIG. 4a also shows that an additional profile 110 (FIG. 4, FIG. 11) 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 (corresponding to the designations of the directions in FIG. 10, see below).
- This is advantageous because, in this way, correspondingly higher ventilation cassettes 14 can be integrated into the frame 1.
- FIGS. 9 to 13, in particular FIG. 10. both the outer frame profile 101 and the additional profile, which is placed on the outside of the upper 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 frame and preferably, exclusively in an insulating web zone, which is formed from insulating webs - that is, in particular from webs made of plastic (see Fig. 3a for the insulating webs, a cassette 14 is not shown here, it would be in Area of the insulating webs 101c provided, which (and preferably only these) would then have the recess 13.).
- the ventilation duct 8 is also formed in one or more ventilation cassettes 14, each of which is inserted into a recess 13, in particular in a milled recess in the frame 1 (or the casement 2) For example, continuous or starting from the frame rebate space, a ventilation cassette 14 preferably being used in this milled recess.
- the recesses 13 are preferably formed in such a way that the insulating webs 101c in this area - possibly up to foot areas in the receiving grooves 101d of the metal shells - are completely removed. If necessary, parts of the receiving grooves 101 d are also milled away without damaging the hollow chamber plane from the hollow chamber or chambers 101 e. In this way, machining the cutouts 13 is easy.
- the ventilation cassette 14 takes over the thermal insulation instead of the insulating bars.
- a ventilation duct 8 On the respective frame side on which a ventilation duct 8 is formed, this does not have to extend over the entire length of the respective frame section / frame spar, even according to FIGS. 3b) to e).
- one, two or more ventilation cassettes can be provided on one side of the frame, each spaced apart from one another, so that the sections of Figs. 3b) and c) on the one hand and 3d) and e) on the other hand alternate.
- Several recesses 103c are then to be provided.
- the ventilation cassette 14 is preferably clamped and / or latched there or fastened with fastening means such as one or more screws or adhesive.
- the frame - here the frame 1 - can be made higher in the area of the ventilation cassette 14.
- protruding (through the profile) cassettes can also extend into recesses in the surrounding masonry (not shown here).
- FIG. 9 for example, three of the ventilation cassettes 14 are formed in the upper spar or the upper window frame profile 101 of the window frame 1 or inserted into it. A corresponding number of cutouts 13, here three of the cutouts 13, can then be formed in this frame profile 101.
- the left and right ventilation cassette have already been installed.
- the middle of the Lüftungskas set 14 is shown in a position before assembly, close to the recess 13 of the frame 1, in which it is used.
- the cassettes are preferably mounted on an upper side in the installation position of a vertically aligned window.
- the preferred assembly direction is the direction from the inside to the outside or here from the bottom to the top in the fold in the Recess into it. In this they could be locked, for example, with a locking edge behind egg ner corresponding locking edge of the recess 13 (not shown here).
- the number and the position of the ventilation cassettes 14 are particularly advantageous in the manner shown in the figures, but otherwise also freely selectable or adaptable to the circumstances and requirements.
- the individual cassettes preferably consist of the base element 14, the cover 16 and the insert 141, the latter two elements also being able to form an exchangeable unit.
- the width b of the ventilation cassette 14 is between 30 and 70 mm.
- the depth or height h of the ventilation cassette 14 can be selected as desired. It is preferably between 50 and 150 mm, in particular 60 and 120 mm. A height h of 90 mm is particularly preferred.
- the ventilation cassettes 14 can be mounted flush in the profile fold.
- Known fastening means and fastening methods are suitable for this, such as screwing, jamming, clipping or the like, for example.
- T-nuts can also be used.
- the box can preferably have one more Fastening device for the cover be arranged. In FIG. 8, this is a quarter-circle lever. Clip levers are also possible.
- the cover 16 here has the groove 17 or a corresponding groove contour for receiving a central seal. Further grooves or contours that simulate the folded surface of the profiles are possible.
- the box 141 can preferably consist of a plastic, in particular manufactured in an injection molding process. Other known manufacturing processes are also possible, e.g. gluing or welding several wall parts. Other materials are also possible, e.g. aluminum. Plastic is preferred because of its poor heat conduction.
- the cover 16 preferably has two or more openings 16a, b. They are preferably about 20 mm long, 10 mm wide and are preferably divided by 20 mm wide webs 16c, d. In this way, for example, a comb-like configuration is obtained on both sides of a central longitudinal web, which here has the groove 17.
- the cover 16 preferably simulates the rebate contour, in particular with the receiving groove 17 for the center seal 18, which here also forms a “sliding seal” that seals the gap between the window frame and the sash frame when the sash is partially open.
- the seal can already be an integral part of the cover.
- the groove or the seal is located between the inlet and outlet opening or openings 16a, b of the channel 8.
- One opening can advantageously be provided, but there is a large number of openings and separate ventilation ducts per cassette for sound insulation and a large amount of air (for sound insulation and large amounts of air - depending on requirements) also possible. On the other hand, the openings must not be too small, otherwise sufficient air volumes / air throughput will not be achieved.
- One opening each for inlet and outlet has been found to be the optimum.
- a single U-shaped ventilation duct has proven to be particularly advantageous.
- the channels 8a, b, c, ... are preferably separated from one another.
- different frequency ranges can be more or less well insulated. So others can reduce street noise "Lids with sound-absorbing material can be used to dampen” wind turbine noise "or” playground noise ".
- the system of the cassette can therefore be easily adapted to customer requirements. The system can also be easily changed later.
- the cover 16 is preferably mounted or removed from the box with a screw, clip or lever mechanism for easy operation. This simplifies and facilitates maintenance work.
- cover 16 and insert 14 can jointly form a structural unit. They can then be exchanged together during maintenance, for example when a change interval has elapsed after which it is recommended to change the filter material 141 or then the entire insert 141.
- the insert 141 can be glued, welded or otherwise mechanically connected to the cover 16.
- Known foam materials can be used as sound insulation material 142.
- the already mentioned heavy foils 143 can also be used as an alternative or in addition. Materials like EVA and bitumen can also be used.
- FIG. 14 shows, by way of example, various inserts 141 which are inserted in otherwise identically constructed ventilation cassettes with base element 15 and cover 16.
- the cover 16 can be adapted to the insert 141 with regard to the position of the openings 16a, b.
- Each U-shaped ventilation ducts and inserts with filter material 142 and optional heavy foil 143 are shown.
- the ventilation channels 8 of FIGS. 14 e) to h) have a smaller depth than those of FIGS. 14 a) to d).
- the ventilation ducts 8 can be formed from the interaction between the walls of the insert 141 and the base element 15 and the cover 16.
