Description

Window with ventilating duct

Technical Field

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

Background

Such a window for sound damping and ventilation in a tilted or pivoted sash position is known per se, for example from DE 102016115422. However, this type of construction has a relatively complex design, so that it is also to be optimized in this respect and in accordance with variants in various other special aspects. In this regard, the problem is that the ventilation ducts formed in the frame are very difficult to clean and maintain. Furthermore, this known structure requires a large operating force when closing the sash. Disadvantageously, in particular, the intermediate seal of the jamb frame is liable to disadvantageously slide on the partition plate of the sash frame. Furthermore, as a disadvantage, it should be mentioned that the opening width is small in the ventilation position. Here, the opening width is mainly also limited by the (short) partition plate of the sash frame as a sliding surface.

Disclosure of Invention

The invention should therefore take different approaches and should achieve an optimized window with ventilation ducts.

The invention achieves the object by the subject matter of claim 1 and claim 4 and also achieves an advantageous ventilation box for such a window. The invention also provides an advantageous method.

A window is realized according to claim 1, which has at least the following features: a frame composed of a plurality of frame section bars; a window sash frame, which is composed of a plurality of frame profiles and which preferably has at least one surface element and which can be moved relative to the frame at least between a closed position and a ventilation position, wherein a circumferential frame tongue and groove space is formed between the frame profiles of the frame and the frame profiles of the window sash frame; at the door frame at least one ventilation duct that constitutes in at least one frame section bar in the frame section bar or in at least one frame section bar in the frame section bar of casement frame, ventilation duct has first ventilation duct opening and second ventilation duct opening, and wherein, casement frame and door frame framework cause, in its mutually supporting at least one ventilation duct opening in the closed ventilation duct opening in first closed position to release in the second position, ventilation position promptly two ventilation duct openings of at least one ventilation duct. The window, also referred to below as a ventilation window, according to the characterizing portion of claim 1, further characterized in that the window, one or a plurality of ventilation ducts are respectively formed in at least one ventilation box or a plurality of ventilation boxes, said ventilation boxes being incorporated in a frame or a sash frame profile, or in a corresponding frame or sash frame profile.

This considerably simplifies the construction of the ventilation duct, since it does not have to be formed in a complicated manner directly in the cavity profile. Instead, it is merely necessary to provide or form a recess in this case and then to insert, for example snap-fit or clip, the preassembled ventilation cassette into the recess. This makes it easy to construct the ventilation duct in the ventilation window.

In this case, the respective ventilation box can be inserted in the respective cheek frame profile or the respective window sash frame profile into the recess of the frame tongue space, simply and preferably from the outside, in the closed position.

In this case, it is preferably provided that the ventilation box has an insert which is inserted into a, in particular, basin-shaped base element of the ventilation box. In this case, it is particularly preferred that the insert of the ventilation cassette inserted into the window is exchangeable, which simplifies the maintenance of the ventilation window.

Thus, the invention achieves, according to claim 4, a window which has the features of the ventilation window of claim 1 in the preamble and the following combination of features in the features section: one or a plurality of ventilation ducts constitute in at least one ventilation box or a plurality of ventilation box respectively, the ventilation box loads into door frame or casement frame or loads into corresponding door frame section bar or corresponding casement section bar, wherein, corresponding ventilation box has built-in, during the built-in basic component of the basin form of ventilation box is packed into, the built-in of installing the ventilation box in the window is removable, and needn't demolish basic component. In this way, only the insert has to be replaced in the case of maintenance, which is particularly simple.

The term "window" should not be understood to be too narrow. This term includes elements having a frame and a fan frame that is movable relative to the frame. The frame may or may not be designed to surround, as is the case for doors. Thus, a door is also a window in the sense of this document. The window may be installed in an exterior wall opening of an exterior wall or in a partition of a building. But the window may also be designed as part of the facade or may be built into the facade. Thus, the frame itself may also be constructed as part of the vertical structure.

For particularly simple maintenance, it can be provided that the ventilation box has a cover for covering the base element and, if appropriate, the insert, and that the cover is detachably fastened to the base element by means of a fastening structure that can be released.

It can be advantageously and simply provided that a sealing groove is formed on the venting box, in particular on the cover.

In a particularly simple manner, the insert and the cover form a structurally exchangeable unit.

Here, the respective insert may consist of one or more materials. For example, the insert can have a filter material. It is also possible to provide that the insert has a film, in particular a thick film.

In a further embodiment, the insert element can be designed to divert the air flow once or several times and/or to divide the air flow into a plurality of partial air flows when it is inserted into the base element. This makes it possible to achieve particularly good sound insulation properties.

It is possible to provide that the respective ventilation box is inserted into a respective recess of the respective cheek frame profile or of the respective sash frame profile which faces the frame tongue space. Since here installation and maintenance can be carried out particularly simply.

It is also possible to provide for a plurality of ventilation boxes to be inserted into the respective recesses of the respective cheek frame profile or of the respective sash frame profile which face the frame space. The corresponding ventilation box can thus have a compact size and maintenance remains simple.

Preferably, but not necessarily, it is provided that the ventilation box is provided only in the side of the frame which is upper in the installed state.

The invention also achieves a ventilation box for a window according to any one of the preceding claims, in which ventilation duct or ducts are formed, which ventilation box has an insert which is inserted into a base element of the ventilation box, wherein the insert of the ventilation box inserted into the window is exchangeable without having to remove the base element. With such a ventilation box, maintenance of the ventilation window becomes particularly easy.

It can further advantageously be provided that each ventilation box has a ventilation duct opening, and that the ventilation duct openings are oriented toward the frame tongue-and-groove space. It can be provided particularly advantageously that the ventilation duct opening is situated completely in the frame groove space between the stop seals in the closed state. Thereby not changing the appearance of the window. The preferred design of the appearance is still retained. Furthermore, the ventilation cassette can thereby be replaced very easily. This is required to be done approximately every year to meet the requirements for cleanliness (dust, insects, etc.). No specialist personnel are required for such replacement.

It is advantageous and simple in construction to provide the ventilation box with an intermediate seal, in particular a groove of the ventilation box.

It is further contemplated that the window sash may be movable at least one location between 50mm and 80mm relative to the frame when the window sash is moved from the closed position to the ventilation position.

High sound insulation values can be advantageously achieved overall. Here, the air exchange capacity may be greater than 12m at 2PA (Pascal air pressure)³H (preferred)>14) And can be more than 25m at 10PA³H (preferred)>28) (air pressure difference between the inside and outside, for example caused by wind pressure or static pressure difference). Preferably, synthetic microfibers are provided in the ventilation box, said microfibers being capable of filtering pollen. This is particularly beneficial for allergy sufferers.

After a set time interval, for example after one or more years, the ventilation box can simply be cleaned and/or replaced after opening the window. The ventilation box can be secured to the frame in a variety of different ways, such as by clamping or preferably by a securing structure, such as at least one screw. It is also conceivable to replace the filter material in the ventilation cassette when the ventilation cassette is provided with said filter material.

In this case, the ventilation box may have the features of one or more of the preceding claims relating to ventilation windows.

Finally, a method for constructing a ventilation duct in a window according to one or more of the preceding claims is also realised, characterized in that a frame profile of a frame is provided; then, a gap facing the frame rabbet space is formed in the corresponding cheek frame section bar, and a ventilation pipeline can be formed in the cheek frame section bar; and the ventilation box is installed in the gap of the corresponding cheek frame section bar or the corresponding window sash frame section bar facing the frame rabbet space, and the ventilation box is provided with a replaceable built-in piece.

According to a further alternative embodiment, it is advantageous if at least one sealing layer is formed between the cheek frame and the sash frame in the region of the frame tongue space in the open state, said sealing layer being formed by at least one sealing element which, at least in the ventilation position, bears with the contact sliding section against the cheek frame or against the sash frame.

In accordance with a further alternative embodiment, it can be provided that in the ventilation position the contact sliding section bears against a contact sliding strip of the sash or jamb frame, which contact sliding strip is formed on, in particular fixed to, the sash or jamb frame and projects with a free end into the tongue and groove space. It is particularly advantageous for this embodiment if the contact slide rail provides a means for adapting to one or more seals which bear against the contact slide rail. The contact sliding strip can be matched in shape, surface and material to the one or more seals, so that an optimum sliding and/or rolling process is achieved. Thereby minimizing operating forces on the window.

It can be provided here that the contact slide rail is intended only for the abutment of the (sliding) seal provided on the opposite frame, without taking on the other static function of the sash frame. Thus, it is not a slat of the window sash or jamb frame as a whole that has a significant effect or influence on the static characteristics of the window sash or jamb frame, as is the case with the partition panel connecting the two metal shells. Although contacting the sliding slats when closing and opening the sash affects the closing and opening forces, it is preferred that the corresponding sliding seals may abut against the contacting sliding slats during the opening and closing movement and slide if necessary. However, this is also a task of contacting the sliding strip and an advantage of contacting the sliding strip, which can be adapted specifically to the stated advantages and tasks, in contrast to strips or profiles which are used mainly for other purposes.

According to one embodiment, it can be provided that the contact sliding slats extend at a distance from the window sash frame, in particular at a substantially parallel distance, in particular such that the contact sliding slats extend at a distance from a separating web of the window sash frame, which connects the two metal shells of the window sash frame to one another and forms a section of the tongue-and-groove space.

In this way, according to a further advantageous embodiment of the invention, it can be advantageously provided that the seal which comes into contact in the open or ventilating position and optionally also in the closed position of the window is configured as an intermediate seal. The intermediate seal can advantageously be designed again to divide the frame groove space into at least two frame groove space sections such that air can be exchanged between the two frame groove space sections substantially only via the ventilation duct in the ventilation position, and has a sealing base and at least one sealing section which is pivotably fastened to the sealing base and is connected to the sealing base in an articulated manner, with the sealing section resting against the contact slide strip at its free end in the ventilation position at least in the region forming the respective ventilation duct. Here, two or more such intermediate seals may also be provided.

In this case, it may be provided that, in the closed state, at least two or at least three sealing layers are formed between the jamb frame and the sash frame in the frame tongue-and-groove space region. In this case, one or both of the sealant layers may also be formed by one or more stopper seals between the frame and the sash frame. These sealing layers are formed only in the closed state of the sash. When the sash is open, the window is placed in its ventilating position, so that air can be exchanged between the spaces formed in the mounted state of the window, i.e. usually between the inside and the outside, through these open sealing layers and the ventilation duct.

According to one variant, it is advantageously provided that the intermediate seal is fastened to the frame and in particular abuts against the sash frame in the ventilation position.

It is preferably provided that the intermediate seal is secured to the frame and the contact sliding slats are secured to the sash frame. It can be provided that the contact sliding slats are mounted laterally on and/or in the corner regions of the respective window frame profile. In this way, it can be provided that the contact sliding strip is fastened with one end on the metal casing of the sash frame profile on the side of the separating sheet of the sash frame profile. Since in this otherwise normally not used area of the sash frame a structure, such as a groove or the like, provided for fixed contact with the sealing strip, may be well formed and arranged.

According to a further alternative, it can advantageously be provided that at least one intermediate seal bears against the contact sliding strip in both the ventilation state and the closed state. If two intermediate seals are provided, one of these is expediently designed such that it only bears against the contact wiper strip in the closed position, but is spaced apart from the contact wiper strip in the ventilation position, so that the passage to the ventilation duct is open.

It can furthermore be advantageously provided that one or at least one of the intermediate seals is designed as a lip seal with one or more sealing lips, which are each designed to be flexible. Since such a flexible sealing lip can be used to bear against the contact sliding strip, which accordingly does not or hardly impede the opening or closing movement of the sash.

According to one variant, it can advantageously be provided that all the multi-chamber profiles of the frame and/or the sash frame are completely or substantially completely made of plastic. However, the multi-chamber profile can also consist of a plurality of materials, such as metal and plastic. The frame and sash frames are thus preferably formed of profiles having one or more metal shells and an insulating slab on or between the metal shells, respectively. Other structural elements, such as a sash frame and/or a frame, having three metal shells and two spacer plate regions between the metal shells, respectively, are also contemplated.

According to a further alternative, it can be provided that one or more multi-chamber hollow profiles of the frame and/or of the sash frame, which are predominantly composed of plastic according to a variant, have at least one reinforcing lining. The reinforcing insert can be designed here as a metal profile, for example as a pipe. Advantageously, steel pipes, for example square pipes, are simply inserted and screwed into the PVC profile as reinforcing linings.

It is also possible to provide, as reinforcing element, a reinforcing lining made of metal, for example, by coextrusion with a multi-chamber hollow profile made of plastic.

The seals inserted and held in the holding grooves are preferably used as a stop seal and/or an intermediate seal, respectively. Such a seal is advantageous and mainly easy to install. The seal may be laid around without cutting at the corners. By being arranged in the retaining groove, the seal can be easily replaced. The seals can preferably also be welded to one another.

A small, thin-walled seal causes only a small resistance against the seal stop. In addition to this, such a seal is also less susceptible to errors. Thereby advantageously minimizing the operating forces of the element.

The previously described prior art, which is realized by means of a closure device, i.e. a separating sheet, results in a smaller opening width (hardly perceptible in operation). The opening width has only a limited length. In the structure according to the invention, the sliding sealing lip closes the gap between the jamb frame and the sash frame, except for the outer profile edge of the sash profile. Thereby achieving a larger opening width ("W"). Preferably, 50 to 80mm is achieved, depending on the profile width ("B"). The geometry of the sliding seal, in particular the length of the sealing lip, is also decisive. Overall, that is to say, a greater width can also be achieved. Widths of 55 to 65mm are particularly preferred. As an equation for the maximum opening width for soundproof ventilation, Wmax may be set to B-25 mm.

Advantageously, the intermediate seal has a seal base and a seal portion pivotably fastened to the seal base. The sealing section is preferably designed as a pivotable sealing lip. Here, the sealing section, in particular the sealing lip, can be hingedly connected to the sealing base.

Advantageous embodiments of the invention can be derived from the other dependent claims.

Detailed Description

Various embodiments are illustrated in the following figures. Various features of the embodiments may be advantageously employed in combination with corresponding other features of the embodiments. These features can also be combined with other exemplary embodiments, which are shown or not, and are also suitable as advantageous embodiments of the subject matter recited in the independent claims and the dependent claims, respectively.

Fig. 1 shows a section of a window. This window has a surrounding frame 1. The frame is composed of a plurality of frame profiles 1', thereby forming a frame shape, in particular a rectangular shape.

And a window sash which can move relative to the frame 1 is arranged on the frame 1. The sash preferably has a sash frame 2 closed at the periphery and an surface element 3, such as a window pane, which is inserted into the sash frame 2 and is received by the sash frame. The sash frame 2 is composed of a plurality of sash frame profiles 2' forming a frame shape, in particular a rectangular shape.

The frame profile 1 'and/or the sash frame profile 2' may be configured as a multi-cavity hollow profile.

The frame profiles can be constructed as plastic profiles. However, the frame profiles may also be designed as so-called composite profiles (fig. 3). In this case, the frame profiles are generally composed of one or more metal profiles, also referred to herein synonymously as metal shell, and one or more spacer plates. A construction form is preferred in which the two metal profile layers are connected to one another via a separating sheet layer, which is usually made of plastic. However, various other embodiments are also conceivable, such as, in particular, embodiments having one metal profile layer and one isolating profile layer made of plastic, and also embodiments having three metal profile layers and two isolating profile layers.

In a corresponding embodiment, a preferably circumferential frame groove space F is formed between the frame 1 and the sash frame 2 or its frame profiles 1', 2'. This frame tongue and groove space F extends substantially between the outer periphery of the sash frame 2 and the inner periphery of the frame 1.

The respective window of fig. 1 or 3 is used for a space opening (not shown here) capable of closing and opening a building, where a space I (e.g., a surrounding space of the building) is separated from a space II (e.g., an inner space of the building).

In this connection, in the following, the terms "cheek frame profile 1 '" and "cheek frame 1" and "sash frame profile 2'" and "sash frame 2", respectively, are also used interchangeably. This is because the structures and designs discussed below may preferably be formed around or partially on the frame 1 or sash frame 2, respectively. Here, the structure and design may be formed on only one of the corresponding frame profiles of the sash frame 2 and the frame 1 (for example, on the frame profile opposite the hinge axis), or alternatively on a plurality of corresponding frame profiles of the sash frame 2 and the frame 1. On the side of the window frame extending perpendicular to fig. 1b, a corresponding gap is also formed in the ventilation position, but the gap does not have a constant width when the window is swung open. In order to increase the ventilation effect, it is also possible to additionally form ventilation ducts 8 of the type according to fig. 1a and 1b, respectively, even on these sides.

The sash frame 2 may preferably have contact strips 4 towards one side or towards the adjacent space II, which in the closed position abut the frame 1 directly or via a stop seal 5 mounted on the sash frame 2. Similarly, the cheek frame 1 may preferably have a contact strip 6 towards the other side or towards the other adjacent space I, in which it rests directly or via a stop seal 7 mounted on the contact strip 6 on the cheek frame 1 (sash frame) in the closed position. In this way, the gap SII and the gap Sl between the frame bezel space F and the space I or II are hermetically closed, respectively.

It is provided here that the ventilation duct 8 (formed along the dashed lines) is formed at least in the frame 1 or in the sash frame 2, here in the frame, and has a first ventilation duct opening 9 and a second ventilation duct opening 10. Preferably, the ventilation duct openings 9 and 10 open into the frame groove space F. The ventilation duct 8 may have a U-shape.

It is also provided according to fig. 1 that at least one or more of the hollow profiles of the frame 1 or the sash frame 2, in which the ventilation duct 8 is formed, is/are designed as multi-chamber hollow profiles made of plastic.

These multi-chamber hollow profiles made of plastic preferably have three or more cavities H1, H2, between the space side I and the space II. According to the embodiment of fig. 1, seven cavities H1 to H7 ("from inside to outside") are provided between space I and space II. Other cavities can also be formed perpendicular to the direction I-II, in particular in the region of the contact strips. These measures ensure, separately and in combination, that very good insulation properties are achieved. The intermediate walls between the cavities in the interior of the profile are preferably thinner than the outer walls, in particular towards the space I and towards the space II.

One or more further cavities H8, H9, H10, H11 may also be provided. One or more of the further cavities H8, H9 may advantageously be provided in the

respective contact strip

4 or 6. These measures, separately or together, further improve the sound and heat insulation.

It can be provided that all hollow profiles of the frame 1 or of the sash frame 2 are designed as multi-chamber hollow profiles made of plastic.

Furthermore, various plastics are suitable as materials. It is particularly preferred that the plastic is PVC. It is furthermore possible for one or more of the multi-chamber hollow profiles of the frame 1 and/or one or more of the multi-chamber hollow profiles of the sash frame 2 to have at least one reinforcing

lining

11, 12.

The

respective stiffening webs

11, 12 can be produced from a different material than the multi-chamber hollow profiles made of plastic, for example from metal, in particular from steel, and can be configured as metal profiles, for example as metal strips or metal plates or the like. The reinforcing lining can also be designed as a reinforcing lining made of another plastic, for example a glass fiber reinforced plastic.

In this case, the multi-chamber profile preferably has a continuous plastic outer wall toward the first space side I and preferably also toward the second space side II.

Furthermore, it is preferred that the ventilation duct 8 is formed in the recess 13, in particular in a milled groove which is formed in the frame 1 or in the sash frame 2, starting from the frame groove space.

In this case, it can also be provided that the ventilation duct 8 is formed in a ventilation box 14 which is inserted into the recess 13, in particular into a milled groove, in the frame 1 or in the sash frame 2. It is also possible to provide a plurality of such ventilation boxes 14 (not shown) for each frame profile or on a plurality of sides of the frame. In this way, the ventilation duct 8 can be simply formed in only one profile or in several profiles of the surrounding frame 1 or sash frame 2.

Preferably, it can be provided that each ventilation box 14 has a trough-like or basin-like base element 15. It is also possible for each ventilation box 14 to have a cover 16.

The cover 16 is preferably oriented here towards the frame tongue and groove space F.

Intermediate seals 18 are preferably formed on the frame profiles, which extend into the frame tongue spaces F. The intermediate seal 18 can be fastened to the ventilation box 14, in particular to the cover 16. For this purpose, a fastening structure, in particular an undercut groove 17, for the intermediate seal 18 can be formed on the venting box 14, in particular on the cover 16.

The intermediate seal 18 can have a sealing base 20 with sealing feet 21 which are inserted into the groove. The seal 18 can furthermore have a sealing section 22 which is pivotably fastened to the sealing base 20. The sealing section 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 itself designed to be curved and/or also has a hinge section, so that it is divided into two lip regions which can be moved relative to one another and which are connected to form a longer sealing lip.

Advantageously, the sealing section 22 can be pivotable relative to the sealing base 21 and has such a length that it can be brought into contact with the sash frame 2. The sealing section preferably adjoins the end section. This end section may be arcuate.

The sealing section 22 may have as end sections a contact-sliding section 23 which, during the relative movement between the frame 1 and the sash frame 2, can be applied to the corresponding frame profile, here to the sash frame profile, and can slide well. This results in a coordinated, easy opening movement which is not significantly impeded by the abutting sealing surfaces.

The contact-sliding section 23 is preferably arranged on the intermediate seal at the location where the ventilation duct 8 is also provided in the respective frame profile. This may be on one side of the frame 1 or sash frame 2 or on multiple sides, preferably on three sides. If the window is an inverted window, the ventilation duct is preferably not formed on the side on which the tilting axis is located. The contact sliding section 23 can now be omitted.

Advantageously, the sealing section 22 is preferably of such a length that it initially rests against the sash frame 2 at a defined opening angle when the sash is open, or at least in the ventilation position described below, rests against the sash frame 2 or comes into contact therewith, so that in the ventilation position it divides the frame groove space F into two regions, between which air exchange takes place substantially exclusively via the ventilation duct 8.

The intermediate seal 18 thus divides the frame-tongue space F into a first and a second region FI, FII (corresponding to the orientation of the spaces I and II), between which air exchange can only take place via the ventilation duct 8 formed in the frame 1.

Alternatively, when the ventilation duct 8 is provided in the frame 1, it may be provided that the intermediate seal is fixed to the sash frame 2 and extends to the frame 1. In this case, the sealing section 22 should preferably also have such a length that, when the window is open, it initially rests against the frame 1 at a defined opening angle, or at least in a ventilation position, which will be described below, rests against or comes into contact with the frame 1, so that in the ventilation position it divides the frame groove space F into two regions, between which air exchange takes place substantially exclusively via the ventilation duct 8.

It should again be pointed out here that this arrangement may also be "completely" reversed, in which case the ventilation duct is located in the sash frame 2. In this case, the intermediate sealing member 18 may be provided from the window sash frame 2 to the frame 1, or vice versa.

In the ventilation position L of fig. 1b, the sash has moved, in particular swung and/or translated, into an open position relative to the frame 1. The open position is a vent position. This open position may, but is not necessarily, correspond to the maximum position that can be reached when tilting or turning or the like.

The gaps SI and SII are open in this position, since the stop seals 5 and 7 no longer abut the frame 1 or the sash frame 2. Said intermediate seal 18 is still in abutment with the sash frame 2. The sash is still partly within the range defined by the sash frame 2. Since the intermediate seal 18 blocks the direct transition between the spaces FI and FII, the air exchange between these spaces FI and FII and thus also between the spaces I and II can only take place via the ventilation ducts. This ensures a very advantageous combination of ventilation and sound insulation.

If the space I is, for example, the surrounding space of a building and the space II is the interior space II of a building, then air can flow into the interior space I through the gaps SI, the frame tongue-and-groove space sections FI, the ventilation ducts 8, the frame tongue-and-groove space sections FII and the gaps SII. In this case, the sound is advantageously blocked, in particular by the deflection of the ventilation duct.

The air which is preferably to flow through the ventilation duct must therefore preferably change direction one or more times. This has a favourable effect on the sound insulation.

The ventilation duct 8 has a first ventilation duct opening 9 and a second ventilation duct opening 10. The two ventilation duct openings 9, 10 can be formed in a ventilation box 14. The two ventilation duct openings 9, 10 are preferably formed in the cover 16.

Furthermore, it can be provided that one or particularly preferably both ventilation duct openings 9, 10 are oriented towards the frame groove space F.

At least one wall 19 can be formed within the aeration tank 14, which wall divides the aeration tank interior into a plurality of sections. The wall 19 may have at least one passage 19 a. In this case, one ventilation duct opening 9, 10 is provided in each of the sections.

In a preferred embodiment, the ventilation duct 8 extends substantially U-shaped within the ventilation box 14 or also without the ventilation box. From the first ventilation duct opening 9, said ventilation duct extends substantially parallel to the surface element 3 into the ventilation box 14 and then substantially perpendicular to the surface element 3, wherein said ventilation duct extends through the passage 19a of the wall 19 and again substantially parallel to the surface element as far as the ventilation duct opening 10. Thus, the direction of the air flowing therethrough is changed many times. This obstructs or prevents the passage of sound from space I to space II and vice versa. But the air flow can still pass from space I to space II for ventilation.

Ventilation boxes 15 (see e.g. fig. 3b) to d) may also be provided in the embodiment of fig. 3), as will be explained in more detail below). In this case, in fig. 3, the ventilation box can be inserted, in a similar manner to fig. 1, into a cavity, in particular a milled groove, of the frame, and/or the ventilation box can completely replace one or more otherwise provided partition panels in its area. The ventilation duct may be formed directly as a channel-like milled groove in the frame of the door frame, or it may be defined by a channel-like element which is inserted into the milled groove.

Furthermore, it is also possible to provide a contact slide strip 24 on the sash frame 2 or on the sash frame profile 2' thereof. The intermediate seal 18 can now rest against the contact slide rail in the ventilation position L. Alternatively, the contact slide rail 24 can also be designed such that the intermediate seal 18 also bears against it in the closed position.

It can advantageously be provided that the contact sliding strip 24 is arranged laterally further away and/or in a corner region of the respective sash frame profile 2'. This corner region is preferably the corner region closest to the respective frame profile 1' in the open and ventilated position. In this way, the contact sliding slats can be located, for example, laterally outside the region defined by the outer edge planes of the inner and outer portions of the insulating glass pane. This is the case, for example, in fig. 1. This is also the case in fig. 3, except that here the contact sliding strip is preferably fixed to one of the metal profiles, in particular to one of the aluminium profiles of the structure.

However, the contact wiper strip 24 can also extend in the groove space to such an extent that the intermediate seal 18 also bears against the contact wiper strip in the closed state.

In this way, a large opening width can always be achieved particularly advantageously, in which air is exchanged between the spaces I and II substantially only via the ventilation duct 8.

The contact slide slats 24 may be made of metal or other materials, such as plastic. Furthermore, the contact sliding strip itself also has at least one cavity.

Furthermore, the contact sliding strip 24 can also be advantageously designed as an attachment strip which is fixed to the respective sash frame profile 2' by means of a fixing structure, for example a groove/key connection.

According to the embodiment of fig. 1, the frame profile, in particular the outer wall with respect to the spaces I and II, is made of a plastic material, preferably PVC. The frame profile is preferably composed entirely of plastic, optionally with the exception of an internal reinforcing profile or reinforcing lining. The frame profile can be designed in one piece, in particular if it is made of plastic.

The outer wall of the cavity profile made of plastic preferably has a thickness of 2-4mm, while the thickness of the partition walls forming the cavities H1-H7 may be 1-2 mm.

In a preferred embodiment,

additional reinforcement plates

10, 11 made of metal are optionally provided in the cavity in order to achieve a static reinforcement, and said reinforcement plates further separate the cavity.

Particularly preferably, as frame profiles 1', 2', use is made of frame profiles with embedded reinforcing profiles, which are produced by coextrusion, the reinforcing liners here being made of aluminum or fiber-reinforced plastic.

Preferably, the stop seals (inner/outer) 5, 7 and the intermediate seal 18 are designed in a circumferential manner, i.e. extend on four sides of the frame, while the sealing sections are not arranged on all sides of the frame.

In the structure according to the invention, the contact sliding section 23 closes the frame tongue-and-groove space or gap between the jamb frame and the sash frame, except for the outer profile edges of the sash frame 2. A larger opening width ("W") is thereby achieved compared to the prior art. Depending on the profile width ("B" between space I and space II), the opening width is preferably up to 50 to 80 mm. The geometry of the sliding seal, in particular the length of the sealing lip, is likewise advantageous. A larger opening width can be achieved overall in the ventilation position. Widths of 55 to 65mm are particularly preferred. As a formula for the maximum opening width for soundproof ventilation, there can be set: wmax is B-25 mm.

A significantly larger number of cavities has a favourable effect on sound insulation compared to aluminium composite structures.

By using a contact slide strip 24, the friction of the sliding seal on the sash frame can be minimized. That is, the material and the surface structure are adapted to each other. Preferably, the sliding seal has a roughened surface structure on the sliding side. The contact sliding strip is preferably characterized by a sliding coating. Of course, the surface structure can also be formed in a different manner.

The interior H7 is preferably not used directly as a ventilation duct, since this is disadvantageous for reasons of sound insulation technology. Instead, two chambers can be formed between the ventilation box wall and the outside, which chambers are particularly preferably separated from one another by an aluminum wall section.

In accordance with fig. 2a and b, in addition to the design shown in fig. 1a and b, a further sealing lip 25 is formed on the sealing base 20 on the intermediate seal 18, which sealing lip rests against the window sash frame 2 in the closed state, so that advantageously four sealing layers are formed between the frame cheek and the window sash frame, even in regions in the frame groove space.

It is particularly advantageous for the contact sliding strip 24 to provide a component adapted to one or more corresponding seals against which the contact sliding strip bears. The contact slide strip 24 can be adapted in shape, surface and material to the seal in order to achieve an optimum sliding and/or rolling process. Thereby minimizing operating forces on the window. That is, the seal "slides/rolls" on the contact sliding strip 24 until it is no longer in contact with the frame profile.

The optimum coefficient of friction is achieved with a slightly roughened surface. The separator plate is typically very smooth, so that the seal is prone to sticking on the separator plate. In contrast, metal, in particular aluminum, is preferably used as the material for the contact sliding strip 24. According to an advantageous variant, the rough surface can be realized by deep-hole anodic plating. A special coating which after drying forms a slightly rough surface can also be used to produce a slightly rough surface. Finally, it is also possible to coat or surround injection-mold a plastic that obtains a surface that is well suited for contacting the sliding strip.

The overmolding can be achieved, for example, by extrusion. It is important that the contact sliding strip can be optimally adjusted for the seal. This is not possible with system isolation panels.

The function of the ventilation window is present until the seal is lifted from the insulating panel. This limits the opening width. The contact sliding strip according to the invention remains in contact with the seal for a considerably longer time than in the prior art, whereby a larger opening width can be achieved. It is particularly advantageous if the contact sliding strip extends up to the edge of the frame profile, and thus a greater opening width is achieved.

The contact sliding strips 24 are connected to the tongue-and-groove-oriented side of the frame profile to which they are to be fastened. Known connection means, such as screwing, riveting, clamping, gluing, etc., can be used for this purpose. It is preferred to mount the contact-sliding slats on the tongue-and-groove side of the sash frame profile 102 near one edge, in particular the edge facing the interior or exterior space, since this makes it possible to achieve a larger opening width in the ventilation position in a simple manner.

Fig. 3 shows in a) and b) to e) sectional views of two different aluminum composite profile structures consisting of a cheek frame profile 101 and a sash frame profile 102. As is shown by way of example in fig. 3a and 3b) to e), the outer edge of the sash frame profile which is to be fixedly contacted with the sliding strip can thereby be formed by an outer aluminum profile shell. Advantageously, the contact sliding slats can be used in different frame profile systems as desired. These slats can also be easily replaced in case of repair or wear.

As shown in fig. 3a) to e), the frame profile 101 in this variant can have a first metal shell 101a and a second metal shell 101 b. The two

metal cases

101a and 101b may be connected to each other through a partition plate 101c (or partition plates). Furthermore, the sash frame profile 102 may have a first metal shell 102a and a second metal shell 102 b. The two

metal cases

102a and 102b are connected to each other by a partition plate 102c (or partition plates). In the installed state, the

first metal shells

101a, 102a may be oriented towards the outside I of the building and the second metal shells may be oriented towards the inside II of the building. The insulating glass sheet 103 is fitted into the window sash frame.

In the tongue-and-groove F between these frame profiles are provided an intermediate seal 104 and a sliding seal 105. The intermediate seal and sliding seal may be assembled to the cheek frame. Furthermore, the sliding seal 105 additionally functionally forms an intermediate seal and the intermediate seal 104 forms a contact seal which is raised when the window sash is opened, which is not the case for the intermediate and contact seals and also the sliding seal 105.

A variation of the contact sliding strip 124 is provided in the tongue F, opposite the

seals

104 and 105. The contact slide rail 124 is fixed to the sash frame profile 102 in the region of the outer side I. In this regard, the contact sliding strip has a fastening end 124a (this fastening end can also be referred to as fastening base 124a or fastening foot). The securing feet may be configured as protrusions that fit into the slots 102 d. The projection may alternatively or additionally also be clamped and/or latched here.

Thus, the fixing seat 124a may be embedded in the groove 102d of the sash frame profile, in particular in the first metal shell 102a (preferably towards the outer side I). Additionally and/or alternatively, the fixed end 124a may be secured thereto using a securing structure, such as by screwing.

Starting from the fastening end 124a, the contact sliding strip 124 projects slightly into the tongue F in the direction of the jamb frame profile 101 and then extends, at a distance from the partition 102c of the sash frame profile, next to the partition in the direction of the second metal shell 102b of the jamb frame 102, without contacting the latter.

Here, the contact sliding strip of fig. 3b) to e) has a cable receiving groove 134 on its end, into which a cable 135, for example a cable 135 having one or more electrical and/or optical conductors, can be fixed, for example by latching.

The cable receiving groove can be formed on the insulating plate 102c) of the sash frame profile 102. In this way, cables 135 are well retained in cable receiving slots 134 and protected from damage by contact with sliding slats 124 toward the tongue and groove. The contact slide rail thus also forms a cable retaining rail here, which considerably simplifies the routing of the cable on the sash frame. In the reversed configuration of the contact slide batten on the cheek frame, the cable routing (not shown) is correspondingly simplified.

In the closed position shown in fig. 3a, both

seals

104 and 105, i.e. here the intermediate seal 104 and the sliding seal 105, bear against the contact sliding strip 124.

In this connection, the contact sliding strip 124 protrudes in the groove beyond the insulating panel of the sash frame, but is advantageously not thermally bonded to the insulating panel, so that preferably even a partial gap X can be formed toward the insulating panel.

By means of this advantageous design, the contact sliding strip 24 can be elastically deformed to avoid forces which act in particular when opening and closing the window sash. This advantageously reduces the operating force when opening and closing the window sash. For composite structures, in a preferred embodiment, the contact sliding slats 124 may extend completely approximately to the center of the insulation panel 102 c. The contact slide can also be designed to be longer. The contact slide bar is preferably designed such that in the open position of the sash one of the at least two

seals

104, 105, in particular the sliding seal 105, still bears against the contact slide bar (similar or comparable to fig. 1 b).

Further ventilation openings are described below, in each of which one or more ventilation boxes 14 are arranged. The window itself may be constructed in the form of figures 1, 2 or 3a or 3b) to e). But these windows may also have a structure different from them in detail.

In this respect, the following description relates in particular to preferred features and variants in relation to the ventilation box 14 or to the structure of the window, as far as this relates to the integration of the ventilation box 14 in the respective ventilation window structure. The features of the ventilation box 14 described below can be implemented as advantageous options on a window constructed as shown in fig. 1 to 3 or on a differently constructed window. Furthermore, these features may also be advantageous individually and in combination, that is to say they may also form part of the protective scope or be used to form the protective scope individually or jointly. In the window shown in fig. 3, the ventilation box is preferably able to replace the ventilation duct which is only partially enclosed directly in the frame profile of the cheek.

Fig. 4 thus shows a side view and a perspective view of a further louver in a) and b), which is provided for mounting one (or more) louver boxes, such as, for example, the louver box shown in fig. 3.

The corresponding ventilation box 14 also has a trough-like or basin-like base element 15. Furthermore, the base element 15 is configured here as a cassette. The base element 15 can be closed on the bottom side and on four sides, respectively, and open on the side facing the tongue and groove in the installed state.

Furthermore, it can be provided that the respective ventilation box 14 has a cover 16, in particular on the open side. One or more through openings 16a may be provided in the cover 16. The base element 14 together with the cover 16 forms a box which is closed here with the exception of the opening 16. Preferably, at least two through

openings

16a, 16b are provided. At this time, it is more preferable that the first through port 16a constitutes the first ventilation duct opening 9, and the other second through port 9b constitutes the second ventilation duct opening 10.

However, the first ventilation duct opening 9 may be formed by the plurality of first ports 16a in common, and the second ventilation duct opening 10 may be formed by the plurality of second ports 9 b. In this case, the first and second ventilation duct openings may be interrupted by the first and

second slats

16c, 16d, respectively.

In this way, the base element 15 can have a partially or completely circumferential flange 151. The cover 16 preferably has at least one web 161 or angled structure or corresponding flange, with which the cover 16 rests in the assembled position on the edge or flange 151 of the base element 15. In this way, a defined position of the cover 16 on the base element 15 is simply achieved. Furthermore, the flange 151 of the base element 15 can serve as an advantageous insertion limiting piece when the base element 15 is inserted into the recess 13 of a frame, here a cheek frame, so that the flange fits correctly into the recess 14 in a simple manner when assembled (see also mainly fig. 6 and 13).

Here, the inner space of the venting box 14 may or may not be adapted to the first and second vents 16a, b.

In the latter case, the inner space of the venting box is not filled, but is empty. Thereby achieving a good ventilation effect.

However, as already explained by way of example with regard to fig. 1a, it can also be provided that the interior of the ventilation box 14 is partially filled. In this way, in particular, the noise protection can be further optimized. Furthermore, measures for cleaning the air flow can optionally also be taken.

The ventilation box can be filled with inserts 141, by means of which the ventilation box is divided. The insert 141 is particularly, but not necessarily, advantageous as a replaceable insert. In this way, the insert may be composed entirely or partially of filter material 142. As it flows through the ventilation box 14, particles from the air flowing therethrough may be deposited on or in the filter material. In this way, the air flow is advantageously purified in a filtered manner when flowing through the ventilation box 14 (see fig. 14).

Here, if the ventilation duct extends in the ventilation box 14, the ventilation duct 8 may here only constitute a single duct or it may again be divided into a plurality of sub-ducts 8a, 8b, 8 c. This can improve the filtering effect and control the ventilation effect well. In addition, such sound insulation can be varied in many ways, in particular it can be adapted to the external environment depending on the local conditions at the installation site. Thus, for example, for a ventilation window mounted in a building opening located in a busy street, good noise protection is more important than on a window oriented towards the quiet side of the building.

In order to optimize the noise protection, it can be provided that the insert 141 is made not only of a single material, for example the already mentioned filter material 142, but of two or more materials. In this case, the additional material can be designed such that it further optimizes the noise protection, in particular. In this way, it can advantageously be provided that the filter material 141 is coated on one side with a film 143, for example a so-called thick film.

Here, the cover 16 is preferably oriented toward the frame bezel space F.

Advantageously, the cover part is detachably fastened to the ventilation cassette 14, in particular by inserting a replaceable insert 141 into the ventilation cassette. The ventilation box and the cover can also form a structural unit with the insert 141.

In this case, it can further optionally be advantageously provided that the cover 16 is fixed to the ventilation box 14 in such a way that it can be completely or almost tool-free released and fixed again. For this purpose, a quick closure 143 can be provided, for example, with a fastening lever 144 which is rotatable and can be snapped and/or clamped under the edge of the projection 144 of the base element 15 or a similar structure. In this way, the built-in member 141 can be replaced easily and quickly. However, it is also conceivable to use tools for replacing the insert, for example, in order to release screws which hold the cover on the ventilation cassette 14.

In addition, the intermediate seal 18 can also be fixed to the cover 16. For this purpose, the cover part in particular has grooves 17 on its side facing the tongue and groove, in which grooves sealing feet 21 of corresponding (here: intermediate) seals 18 can be anchored. The slots may be aligned with corresponding slots in the rebates of the cheek frames. In this way, the groove of the frame is advantageously not interrupted on the frame side, and the corresponding seal can also be reliably installed in the region of the ventilation box 14.

For ventilation boxes 14 with replaceable inserts 141, it is particularly advantageous if the inserts 141 of the cover 14 can be easily replaced during operation and thus by the end user himself. The insert exchange is simple, similar to the filter insert exchange of a vacuum cleaner. In general, the vent box 14 itself is also easy to install. The venting box 14 is preferably positioned invisibly in a bezel, which is shown in particular in fig. 4a and b.

Here, fig. 4a also shows that an additional profile 110 (fig. 4, 11) can be added to the upper cheek frame profile 1. The additional profile 110 may be configured to increase the height of the frame 1 (corresponding to the directional references in fig. 10, see below). This is advantageous because it allows the integration of a correspondingly taller ventilation box 14 into the frame 1. This is illustrated, in particular, by way of example in fig. 9 to 13, in particular fig. 10. In this case, the frame profiles 101 and the additional profiles attached here to the frame profiles 101 in the upper middle of the installation site have corresponding recesses 13 for receiving corresponding ventilation boxes.

The ventilation box 4 is preferably installed in the frame of the cheek and preferably only in the partition area, which is formed by the partition, i.e. in particular a plate made of plastic (see fig. 3a for the partition, where the ventilation box 14 is not shown, is arranged in the area of the partition 101c, when these (and preferably only these) have a recess 13).

According to fig. 3b) to e), the ventilation duct 8 is also formed in one or more ventilation boxes 14, which are each inserted into a recess 13, in particular a milled groove, which is formed in the frame 1 (or sash frame 2), for example continuously or starting from the frame groove, into which the ventilation box 14 is preferably also inserted.

The recess 13 is preferably formed in this region of the ventilation box 14 in such a way that the insulating plate 101c is completely removed in this region, if appropriate, except for the foot region in the receiving groove 101d of the metal shell. If necessary, some parts of the receiving groove 101d are milled away without destroying the cavity layer formed by the one or more cavities 101 e.

Thus, the milling groove 13 can be processed easily. The ventilation box 14 takes over the task of insulation instead of the insulation panels.

On the respective frame side on which the ventilation ducts 8 are constructed, said ventilation ducts also do not have to extend over the entire length of the respective frame section/frame beam according to fig. 3b) to e). Thus, for example, one, two or more ventilation boxes can be arranged on one frame side, which ventilation boxes are arranged at a distance from one another, so that the sectional views of fig. 3b) and c) and the sectional views of fig. 3d) and e) are formed alternately. A plurality of voids 103c are provided at this time.

In this way, although it is necessary to provide the ventilation box 14, the production of the frame profile is not further complicated, since the one or more necessary recesses 13 for accommodating the ventilation box 14 (which recesses can also be through openings according to fig. 3b) to e)) can be formed simply in the metal shell and/or in particular in the insulating profile 101c made of plastic. The ventilation box 14 is preferably fixed there by clamping and/or snap-locking or force-fixing structures, such as one or more screws or adhesives.

In order to be able to mount the ventilation box 14 in a very narrow frame profile, the frame, in this case the frame 1, is designed to be higher in the region of the ventilation box 14. But the protruding (through-profiled) ventilation boxes can also project into the recesses of the surrounding wall (not shown here).

In fig. 9, there are illustratively three of the ventilation boxes 14 formed in or incorporated into the upper spar of the frame 1 or the upper frame profile 101. In this case, the number of the cavities 13, here three, may be correspondingly configured in this frame profile 101. The left and right ventilation boxes have been installed. The central ventilation box 14 is shown in its pre-assembled position, i.e., adjacent to the cavity 13 in which the cheek frame 1 is received.

These ventilation boxes are preferably mounted on the side of the upper part in the mounted position of the vertically oriented window. The preferred installation direction is the direction from the inside to the outside or from the bottom to the top in the groove into the recess. In this direction, the ventilation box can be latched behind a corresponding latching edge of the recess 13, for example with a latching edge (not shown here).

However, it has also proven possible to carry out the assembly from the outside, i.e. from the side opposite the tongue-and-groove side. If a replaceable insert 141 is provided, this assembly of the ventilation cassette 14 can be done once at the first assembly. Alternatively, however, the entire ventilation cassette can also be designed to be replaceable. Other possibilities for incorporating the ventilation box are also conceivable. For example, the ventilation cassette may also have laterally accessible replaceable inserts 141 or may be mounted from the side as a whole, which is not particularly preferred for visual reasons.

The number and position of the ventilation boxes 14 are particularly advantageous in the manner shown in the figures, but in addition thereto they can be freely selected or adjusted according to the conditions and requirements.

The individual ventilation cassette preferably consists of the base element 14, the cover 16 and the insert 141, the latter two elements also forming a replaceable unit.

Preferably, but not obligatorily, the width b (fig. 10) of the ventilation box 14 is between 30 and 70 mm. Advantageously, since the ventilation box can be integrated well into a conventional insulation panel having a corresponding width. Especially for plastic windows, the ventilation box may also be wider. The length of the ventilation box itself can be chosen arbitrarily. It is advantageous to design the ventilation box to be between 150mm and 250mm (length l), as a result of which the installation of the ventilation box and in particular the replacement of the insert 141 can be carried out easily. In particular, a length l of 200mm is particularly preferred.

The depth or height h (see fig. 10) of the aeration cartridge 14 may itself be arbitrarily selected. Preferably, the depth or height is between 50 and 150mm, especially between 60 and 120 mm. A height h of 90mm is particularly preferred.

The ventilation box 14 may be flush mounted in the profile rebate. Known fastening structures and fastening methods, such as, for example, screwing, clamping, snapping or the like, are suitable for this. Sliders may also be used. Preferably, a fastening device for the cover can also be provided on the cassette. In fig. 8, this is a quarter-round rod. Snap rods may also be used.

Here, the cover 16 has a groove 17 or a corresponding groove profile for accommodating an intermediate seal. Other grooves or contours that mimic the grooved surfaces of the profile may also be provided.

The ventilation box 141 is preferably made of plastic, in particular by injection molding. Other known manufacturing methods, such as gluing or welding of the various wall parts, may also be used. Other materials, such as aluminum, may also be used. But plastic is preferred due to poor thermal conductivity.

As illustrated, the cover 16 preferably has two or more through openings 16a, b. The through openings are preferably about 20mm long and 10mm wide and are preferably separated by 20mm wide strips 16c, d. Thus, here, a comb-like configuration is formed, for example, on both sides of the central longitudinal strip, which here has a groove 17.

The cover 16 preferably simulates a tongue-and-groove profile, in particular with a receiving groove 17 for the intermediate seal 18, which here also forms a "brush seal" that seals the gap between the frame of the door and the frame of the window when the window is partially open. Alternatively, the seal can already be an integral part of the lid.

The groove or seal is located between the inlet and outlet or through openings 16a, b of the ventilation duct 8. It is also advantageous to provide each ventilation box with one opening, but it is also possible to provide a plurality of openings and separate ventilation ducts for sound insulation and for achieving a large air volume (for sound insulation and a large air volume, as required). On the other hand, these openings cannot be too small, since otherwise a sufficient air quantity/air throughput cannot be achieved. It has proved to be optimal to have one opening for each of the inlet and outlet. A single U-shaped ventilation duct has proved to be particularly advantageous.

The conduits 8a, b, c. By varying the pipe cross-section, different frequency ranges can be attenuated to different degrees. Thus, to block street noise, rather than "wind turbine noise" or "fairground noise", different covers with sound insulation may be used. That is, the system of ventilation boxes can be easily adjusted to customer needs. The system can also be easily changed afterwards.

The cover 16 is preferably mounted or dismounted on the box with a screw mechanism, a snap mechanism or a lever mechanism for simple handling. This simplifies and facilitates maintenance work.

For practical operation, the covering part 16 and the insert part 14 can together form a structural unit. In this case, for example, the cover and the insert can be replaced together during maintenance, for example after a replacement interval, after which the filter material 141 or the entire insert 141 is replaced.

Here, the insert 141 may be glued, welded or otherwise mechanically interconnected with the cover 16.

Known foam materials can be used as the sound insulating material 142. Alternatively or additionally, the already mentioned thick film 143 can also be used. Materials such as EVA and asphalt may also be used.

The main parameters of performance are the sound insulation value (dB), the air Pressure (PA) and the air throughput (m)³H). Because these parameters are directly related, improving one quantity can corrupt the other. However, by structural measures and the selection of the best materials, the performance data can be improved overall. With a ventilation box according to the invention, such as the ventilation boxes exemplarily shown in fig. 9 to 14, the following values can be achieved, for example: at a pressure difference of 2PA between the inside and the outside, the air throughput was 12.7m³H and at 10PA 28.7m³And for tilt windows, sound insulation is 32dB (off 47 dB).

Fig. 14 shows by way of example various inserts 141 which are inserted into an otherwise identically designed ventilation box having a base element 15 and a cover 16. The cover 16 can be adapted to the insert 141, which relates to the position of the openings 16a, b.

Here, a U-shaped extended ventilation duct and an insert with a filter material 142 and optionally a thick film 143, respectively, are shown.

The ventilation ducts 8 of fig. 14e) to h) have a smaller depth than fig. 14a) to d). The ventilation duct 8 may be formed by the cooperation between the wall of the insert 141 and of the base element 15 and the cover 16.
