Definitions

  • the invention relates to a window with a ventilation duct, according to the preamble of claim 1.
  • Such a window which enables soundproof ventilation in a tilted or rotated wing position, is known per se, for example from EN 1 0 2016 115 422 .
  • the generic construction has a relatively complicated structure.
  • the known construction requires relatively large operating forces when closing the wing.
  • a particular disadvantage is that the center seal of the frame slides only poorly on the insulating bar of the casement.
  • the relatively small opening width in the ventilation position should also be mentioned as a disadvantage.
  • the opening width is limited, among other things, by the (short) insulating bar of the sash frame as a sliding surface.
  • the invention should therefore 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.
  • the term window should not be interpreted too narrowly. It includes elements with a window frame and a casement frame that can be moved relative thereto.
  • the window frame can be designed to run all the way round or not to run all the way round, as in the case of a door. A door is therefore also a window in the sense of this document.
  • 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 be built into one. The window frame can thus itself form part of a facade construction.
  • the contact sliding strip provides a component that is adapted 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 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 contacting the (sliding) seal arranged on the opposite frame and does not assume any further static function of the casement. It is therefore not an integral strip of the casement or window frame that contributes significantly to its statics or influences it, as is the case with an insulating strip that connects two metal shells.
  • contact sliding strip influences the closing and opening forces when closing and opening the sash, since a corresponding sliding seal is preferably in contact with it and can possibly slide during the opening and closing movement. But this is also one of its tasks, as well as one of its benefits, to which it can be specifically adapted, unlike bars or profiles, which primarily serve other purposes.
  • the contact sliding strip has an elongated, web-like, in particular elongated arc-like, shape with two ends in cross section, one of the ends being fixed to the sash frame or the window frame and the other free end protruding into the rebate space .
  • an additional strip is created for the frame profiles that are actually present on the casement frame (or the window frame), which can preferably be designed exclusively and thus optimally for the task as a particularly well-suited system for the one or more seals of the corresponding frame - window frame or Casement - to serve to close the ventilation duct at least in the opening and ventilation position of the casement relative to the frame.
  • This system sliding strip is particularly suitable for use on aluminium-plastic frame profiles.
  • the contact sliding strip extends in sections at a distance, in particular essentially parallel, to the sash, in particular in such a way that the contact sliding strip extends in sections at a parallel distance from an insulating bar of the sash, the two metal shells of the Connecting the casement to each other and forming a section of the rebate space.
  • the advantageous system sliding strip can be ensured in such a simple way that the system sliding strip does not have to rest on the insulating bar, which is usually made of plastic, which means that the window can be opened due to the relatively high frictional forces between the insulating bar and the one or would adversely complicate the several investment webs. It can also be provided that the contact slide strip extends in sections at a distance from an insulating bar of the casement, which connects two metal shells of the casement to one another and forms a section of the rebate space.
  • the contour of the curved contact sliding strip corresponds to the contour or path that the sash takes when moving out of the Closed position and vice versa in the area of the system sliding strip.
  • a curved path is swept over in particular at the top of the wing (on the upper wing frame profile) if the wing can also be pivoted into a tilted position, for which purpose it can preferably have a horizontal tilting axis in its lower region.
  • the seal which comes into contact in the open or ventilation position and possibly also in the closed position of the window, is designed as a central seal.
  • This center seal can in turn be advantageously designed to divide the rebate frame space into at least two rebate frame sections, so that air in the ventilation position can essentially only be exchanged between the two rebate frame sections through the ventilation duct, with the center seal having a seal base and at least one on the seal base pivotally fastened sealing section, which is connected in an articulated manner to the sealing base, the sealing section at least in the area or areas in which a respective ventilation duct is formed being in the ventilation position at its free end with the contact slide section on the contact slide strip. Two or more such center seals can also be provided.
  • One or two of the sealing planes can also be formed by one or more stop seals between the frame and the casement.
  • the middle seal is fastened to the window frame and is located in contact with the casement frame, in particular in the ventilation position.
  • the contact sliding strip is attached to the side of and/or in a corner area of the respective corresponding casement profile. It can also advantageously be provided that the center seal is designed as a lip seal with one or more sealing lips, each of which is designed to be flexible.
  • the shape, surface and/or material of the contact sliding strip and the contact sliding section are matched to one another and correspond to one another.
  • the center seal is fastened to the window frame and the contact sliding strip to the casement frame.
  • the contact sliding strip is mounted on the side and/or in a corner area of the respective corresponding casement profile. Provision can thus be made for the contact sliding strip to be fixed with one of its ends to a metal shell of the casement profile on the side of an insulating strip of the casement profile. Because in this otherwise usually unused area of the casement, the means to be provided for fixing the contact sealing strip, such as a groove or the like, can easily be designed and accommodated.
  • the at least one middle seal is in contact with the contact sliding strip both in the ventilation state and in the closed state. If two center seals are provided, one of the two center seals is expediently designed in such a way and the other in such a way that it only rests against the contact slide strip in the closed position, but is spaced from it in the ventilation position, so that access to the ventilation duct is released.
  • one or at least one of the central seals is designed as a lip seal with one or more sealing lips, each of which is designed to be flexible. Because in this way the flexible sealing lips can be used to rest on the system sliding strip, which the opening movement or the closing movement of the sash accordingly not or hardly impede.
  • the shape, surface and/or material of the contact sliding strip and the contact sliding section can be or are matched to one another and correspond to one another.
  • the materials can be matched to one another in such a way that the seal can easily slide along the contact sliding strip with its contact sliding section. This is achieved, for example, when the contact slide strip consists entirely or in sections of metal, in particular an aluminum alloy, and the contact slide section consists of an elastomer. Sections of the contact sliding strip can also consist of an aluminum alloy and sections of a plastic.
  • the sliding seal can preferably also have a roughened surface structure on the sliding side.
  • the contact sliding strip can have a corresponding anti-friction coating.
  • the surface structure can also be designed the other way around. Provision can therefore be made for the sliding contact section to have a roughened surface structure on the sliding side and/or for the sliding contact strip to have a sliding coating or for the sliding contact strip to have a roughened surface structure on the sliding side and/or for the sliding contact section to have a sliding coating.
  • one of the ends of the contact sliding strip extends to an edge or just in front of an edge (i.e. to less than 10 mm in front of the edge) of the frame profile of the casement to which it is fixed is.
  • the fixing of the contact sliding strip on the frame profile can be done in a variety of ways, such as by screwing, riveting, clipping, gluing.
  • contact sliding strips of the casement frame which adjoin one another at a corner are connected to one another via corner connector contact sliding pieces.
  • an all-round “sliding frame” can be formed on the casement frame (or window frame), which also ensures good sealing of the ventilation duct in these corner areas
  • the frame profiles can also have multiple layers. They can have, for example, two metal shells and an insulating strip level between them, but they can also have a metal shell and a plastic shell. However, they can also be constructed with five shells or as non-multiple shell or single shell plastic profiles, in which case these can optionally have reinforcements or the like.
  • all of the multi-chamber profiles of the window frame and/or the casement consist entirely or essentially entirely of plastic.
  • one or more of the multi-chamber hollow profiles made of plastic of the window frame and/or the casement, which essentially consist of plastic have at least one reinforcement insert.
  • the reinforcing insert can be designed as a metal profile, for example as a tube. It is advantageous if steel tubes, e.g. square tubes, are simply inserted and screwed into the PVC profiles as reinforcement inserts.
  • a reinforcement reinforcement e.g. made of metal in coextrusion with the multi-chamber hollow profile made of plastic, is produced.
  • seals are used that are inserted into and held in retaining grooves.
  • Such seals are relatively inexpensive and, above all, easy to assemble. They can be laid all around without being cut in the corners. The seals can be easily replaced due to the arrangement in retaining grooves.
  • the seals can preferably also be welded to one another.
  • the stop seals (inside/outside) and the middle seal are preferably formed all around, i.e. on four sides of the frame, while the sliding seal/sliding sealing lip (separate or integral with the middle seal) is only on one (opposite the tilting axis) side or preferably on three sides (except for the tilting axis).
  • the center seal may be formed as a lip seal having one or more sealing lips, each relatively thin and flexible.
  • a large-volume multi-chamber central seal is advantageously not necessary in this way.
  • the seals are advantageously made of a weldable TPE or weldable EPDM. In this way, profiles with inserted seals can be welded to frames at the same time.
  • the sliding seal is designed with multiple joints and has a curved sliding surface which, together with the contact sliding strip attached to the frame, forms a particularly favorable friction pairing.
  • the surface structures and the combination of materials are important here in order to achieve an optimal result.
  • the relatively small opening width results from the prior art mentioned at the outset due to the sealing means, the insulating bar.
  • This has only a limited length.
  • the sliding sealing lip closes the gap between the frame and the casement up to the outer profile edge of the casement profile. This achieves a larger opening width ("W").
  • W opening width
  • B profile width
  • 50 to 80 mm are preferred.
  • the center seal has a seal base and a seal section pivotally attached to the seal base.
  • This is preferably designed as a pivotable sealing lip.
  • the one or more ventilation ducts is/are each formed in a ventilation cassette, which is/are inserted in the window frame or the casement.
  • the formation of the ventilation duct is significantly simplified because it does not have to be formed directly in the hollow chamber profiles, which is laborious. Rather, it is sufficient to provide or form a recess there and then to insert the pre-assembled ventilation cassette into the recess, for example to engage or clamp it.
  • the respective ventilation cassette can be inserted in a simple manner and preferably not visible from the outside in the closed position in a recess of the respective window frame profile or the respective casement profile facing the frame rebate space.
  • the ventilation cassettes can be changed very easily in this way. This is required approximately once a year in order to meet cleanliness requirements (dust, insects, etc.). No specialist is required for the replacement.
  • the air exchange can be more than 12 m 3 /h (preferably >14) at 2 Pa (Pascal air pressure) and >25 m 3 /h (preferably >28) at 10 Pa.
  • Synthetic microfibers that are able to filter pollen are preferably arranged in the ventilation cassettes. This is particularly beneficial for allergy sufferers.
  • this cassette can be cleaned and/or changed simply after opening the window, for example after one or more years.
  • the ventilation cassette can be connected in a variety of ways be fixed to the frame, so clamping or preferably with a fastener 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.

  • This is composed of several window frame profiles 1' to form a frame shape, in particular a rectangular shape.
  • the wing On the frame 1 relative to the frame 1 movable wing is arranged.
  • the wing preferably has a peripherally closed wing frame 2 and a surface element 3 inserted into the wing frame 2 and accommodated by it, such as a disk.
  • the wing frame 2 is composed of several wing frame profiles 2' to form a frame shape, in particular a rectangular shape.
  • the frame profiles 1' and/or the casement profiles 2' can be designed as multi-chamber hollow profiles.
  • the window frame profiles can be designed as plastic profiles. However, they can also be designed as so-called composite profiles ( Fig. 3a - e )). Then they usually consist of one or more metal profiles - also synonymous here called metal shells - and one or more insulating bars. Preferred is one Construction in which two metal profile levels are connected to one another via an insulating strip level, which is usually made of plastic. However, other, further designs are also conceivable, in particular designs with a metal profile level and an insulating profile level made of plastic, as well as designs with three metal profile levels and two insulating profile levels.
  • a preferably circumferential frame rebate space F is formed between the outer frame 1 and the sash frame 2 or their frame profiles 1′, 2′.
  • This frame rebate space F essentially extends between the outer circumference of the sash frame 2 and the inner circumference of the window frame 1.

  • the center seal 18 is still in contact with the casement frame 2.
  • the casement is still partially within the scope defined by the frame 2. Since the central seal 18 blocks the direct transition between the spaces FI and FII, an exchange of air between these spaces FI and FII and thus also an exchange of air between spaces I and II can only take place through the ventilation duct. This provides a very advantageous combination of a ventilation and a soundproofing effect.

  • the ventilation duct 8 runs within the ventilation cassette 14 (or also without a ventilation cassette) in an approximately U-shape. 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, extends there through the passage 19a of the wall 19 and again runs approximately parallel to the surface element up to the ventilation duct opening 10 changes multiple times the direction of airflow. 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 in the embodiment of Fig.3 be provided (see e.g Figure 3b ) to e), will be explained in more detail below). You can then analogous to 1 be used in a chamber, in particular a cutout of the window frame and/or it can completely replace one or more insulating bars that are otherwise provided in its area.
  • the ventilation duct can also be formed directly as a channel-like cutout in the window frame or it can be delimited by channel-like elements which are inserted into these cutouts.
  • the middle seal 18 can then lie against this in the ventilation position L.

  • Figures 2a and b is complementary to the construction of the Fig. 1a and b intended to form a further sealing lip 25 on the central seal 18 on the sealing base 20, which rests against the casement 2 in the closed state, so that four sealing planes are advantageously formed in the frame rebate space between the frame and the casement.
  • What is particularly advantageous about the contact sliding strip 24 is that a component adapted to the one or more corresponding seal(s) against which it rests is provided.
  • the system sliding strip 24 can be placed on the seals in shape, surface and material, so that an optimal sliding and / or unrolling is achieved. This reduces the operating forces at the window to a minimum.
  • the seals "slide/roll" on the contact sliding strip 24 until they no longer have any contact with the frame profile.
  • the best friction values are achieved with a slightly rough surface.
  • Insulating bars are usually very smooth, so seals tend to stick to them.
  • a metal in particular aluminum, is preferably used as the material for the contact sliding strips 24 .
  • the rough surface can be achieved by deep-pored anodizing. Special paints that form a slightly rough surface after drying can also be used to create a slightly rough surface.
  • plastics can also be applied or overmoulded, which gives them well-suited surfaces for the system slide rail,
  • Overmoulding can be realized, for example, in an extrusion process. It is important that the system slide rail 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 contact slide strip stays in contact with the seal much longer than was the case in the prior art, which means that a larger opening width can be achieved.
  • the contact sliding strip extends to the edge of the frame profile and thus enables a larger opening width.
  • the contact sliding strip 24 is connected to a side of the frame profile, which is directed towards the fold, to which it is to be fastened.
  • Known connection options such as screws, rivets, clips, adhesives, etc. are available for this purpose.
  • figure 3 shows in a) and in b) to e) a section through two different aluminum composite profile constructions consisting of a frame profile 101 and a casement profile 102.
  • the outer edge of the casement profile, to which the sliding strip system is to be attached can thus be formed by an outer aluminum profile shell. It is advantageous that the system slide rails can be divided into different Frame profile systems can be used. The strips can also be easily replaced in the event of repairs or wear.
  • the window frame profile 101 can - as in Figure 3a ) to e) - have a first metal shell 101a and a second metal shell 101b in these variants.
  • These two metal shells 101a and 101b can be connected to one another via an insulating bar 101c (or several insulating bars) ( Figure 3a ) to e). These insulating webs 101c can engage at their ends in receiving grooves 101d of the two metal shells 101a, 101b and be fixed there (eg by rolling a wall of the respective receiving grooves).
  • the two metal shells 101a and 101b preferably each have at least one hollow chamber plane made up of one or more hollow chambers 101e.
  • the casement profile 102 can also have at least one first metal shell 102a and one second metal shell 102b. These two metal shells 102a and 102b are connected to one another via an insulating bar 102c (or a plurality of insulating bars).
  • 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 central seal 104 and a sliding seal 105 are arranged in the fold F between the frame profiles. You can be attached to the frame. Functionally, the sliding seal 105 also forms a type of center seal and the center seal 103 a type of contact seal, with the latter being lifted off the sash when it is opened, which is not the case with the center and contact seal and also the sliding seal 105 .
  • This contact sliding strip 124 is fastened to the casement profile 102 in the area of the outside I.
  • This contact sliding strip 124 has a fastening end 124a (which can also be called fastening base 124a or fastening foot).
  • the mounting foot can be formed as a projection that engages in the groove 102d. Alternatively or additionally, it can also be clamped and/or latched there.
  • the fastening base 124a can thus be inserted into the groove 102d of the casement profile, in particular in the first metal shell 102a (preferably towards the outside I), intervention. Additionally and/or alternatively, the fastening end 124a can be fastened there with a fastening means, for example screwed tight with a screw.
  • the contact sliding strip 124 protrudes slightly into the fold F in the direction of the window frame profile 101 and then extends at a distance from the insulating web 102c of the casement profile next to this in the direction of the second metal shell 102b of the casement frame 102, but does not touch it.
  • the plant-slide bar Figure 3b ) to e) at its end has a cable receiving groove 134, in which a cable 135, for example a cable 135 with one or more electrical and/or optical conductors, can be held, for example by latching.
  • the cable receiving groove can be formed on the insulating strip 102c) of the casement profile 102.
  • the cable 135 is held securely in the cable receiving groove 134 and is protected from damage towards the fold by the contact sliding strip 124 .
  • the contact sliding strip also forms a cable holding strip here, which significantly simplifies the laying of a cable on the sash frame. In the case of an inverted construction with a contact sliding strip on the frame, laying a cable on the frame is simplified accordingly (not shown).
  • the contact sliding strip 124 protrudes in the rebate over the insulating bar of the sash, but it is thermally advantageous not to rest on the insulating bar, so that a gap X can preferably even form in sections towards the insulating bar.
  • the contact sliding strip 124 can be resiliently deformed in order to avoid forces acting in particular when the sash is opened and closed. This advantageously reduces the operating forces when opening and closing the wing.
  • the contact sliding strip 124 can certainly protrude up to approximately the middle of the insulating web 102c in preferred configurations. However, it can also be made longer. It is preferably designed in such a way that at least one of the two seals 104, 105, in particular the sliding seal 105, rests against it when the sash is in the open position (similar or analogous to Fig. 1b ).
  • the ventilation duct 8 is in turn formed in one or more ventilation cassettes 14, each of which is inserted in a recess 13, in particular in a milled recess, which is in the window frame 1 (or the casement frame 2), e.g. continuously or starting from the Frame rebate space is formed, in turn, a ventilation cartridge 14 is preferably used in this cutout.
  • the recesses 13 are preferably formed in such a way that the insulating webs 101c in this area--possibly except for the foot areas in the receiving grooves 101d of the metal shells--are completely removed. If necessary, parts of the receiving grooves 101d are also milled away without damaging the hollow chamber plane of the hollow chamber(s) 101e.
  • the ventilation cassette 14 takes over the thermal insulation instead of the insulating bars.
  • a ventilation duct 8 On the respective side of the frame on which a ventilation duct 8 is formed, this does not have to extend over the entire length of the respective frame section/frame beam.
  • one, two or more ventilation cassettes can be provided on one side of the frame, which are each provided spaced apart from one another, so that the sections of the alternately Figure 3b ) and c) on the one hand and 3d) and e) on the other hand.
  • a plurality of recesses 103c are then to be provided.
  • the individual ventilation cassettes can be completely exchanged for new ones. However, it is also conceivable to open it by removing the cover 16, so that its interior—formed, for example, by sound- and/or heat-absorbing material such as foam strips or the like—can be exchanged with it or afterwards.
  • Figure 4a shows a first variant of a contact sliding strip 124 in section.
  • the sliding strip 24 is designed as an elongated web-like element. It extends perpendicularly to the picture plane like a profile bar.
  • One of its ends - attachment end 124a - is designed for attachment to the wing frame. From there it is in front of the fold between the casement 2 and the frame 1.
  • the upper side of the system sliding strip 124 - that is, here the side facing the frame 1 - serves as a contact and sliding surface for the seal 105 - which has therefore already been synonymously referred to as a sliding seal.
  • the contact sliding strip 124 can have an arc shape at least towards this side.
  • This page the contact sliding strip 124, on which at least the central and contact seal as well as the sliding seal 105 rests or slides during the opening or closing process of the sash, is also referred to as the sliding surface 126.
  • This sliding surface 126 can advantageously be adapted to the pivoting radius of the wing, ie it can form a curved surface (large radius). It can also be coated.
  • the fastening area B1 of the contact sliding strip 124 is located on the left side directed towards the outside I.
  • This area B1 can be configured differently.
  • An embodiment as a clip connection for connecting to a corresponding clip element on the casement profile is particularly advantageous. is shown in Figure 4a but again a fastening area B1, which is designed for a screw connection.
  • the contact sliding strip 124 is placed on the casement profile 102 and screwed there.
  • this fastening area B1 is preferably about 1/3 of the total width of the contact sliding strip 124. This means that the area B2 standing freely above the insulating web 102b makes up about 2/3 of the total width. This area B2 should not be more than 3 ⁇ 4 of the total width so that a springy effect is achieved but the area B2 does not become too unstable.
  • Figure 4b shows an alternatively designed contact sliding strip 124. This has a first sliding surface 126 and a second, somewhat offset sliding surface 126'. The shoulder creates a particularly suitable contact surface for a center seal 104 . This variant is also characterized by a hollow chamber 129 .
  • Figure 4c shows a further embodiment of the sliding strip 124 according to the invention.
  • the sliding surfaces are not designed in the form of curves but rather as flat surfaces or slopes.
  • the plant sliding strip 124 of Figure 4c as well as 5a, 5b, 6a and 6b particularly preferably have one, two or more undercut groove(s) 127 which can be provided as connecting grooves for corner connector abutment slides 130.
  • the corner connector attachment sliders 130 are used to connect the attachment slide rails 124 of the various frame members of a sash frame across a corner.
  • corner connector contact slides 130 can have two legs 130a, 130b aligned at an angle to one another, which in terms of their nature each adjoining system slide rails 124 can correspond.
  • the contact sliding strips 124 of the respective frame profiles extend between the corner connector contact sliding pieces 130 of respectively adjacent corners and are preferably flush with them.
  • corner connector abutment sliding pieces 130 and the abutment sliding strips 124 are provided with corresponding latching means and/or form-fitting means - e.g. designed as grooves 127 and lugs 131 - which the corner connector abutting elements in the axial direction -Connect slide pieces and contact slide rail 12 in the direction of the longitudinal extension of the frame bars. Thereby, the corner connector abutment sliders 130 are securely held.
  • corner connector abutment slides 130 By using corner connector abutment slides 130, the corners can be rounded. This is advantageous for the contact of the sliding seals on the contact slide rails. The advantage is that the compressive forces of the seals are balanced in this area, as described above.
  • the contact sliding strips 124 can advantageously extend beyond the corner area.
  • the sliding seal or sliding seal 105 must undergo major changes in shape here, but must only cause the lowest possible forces. Especially in combination with z. B. rounded corner pieces 130, the expansion and thus the operating forces of the sliding seal 105 in corners are significantly reduced and a largely optimal contact situation is produced.
  • the respective contact sliding strip 124 consists of two areas 124' and 124" or sections made of different material.
  • One area 124' can be made of plastic, for example, and the other area 124" can be made of a metal such as aluminum.
  • This sliding contact strip 124 which consists of two material areas, can be manufactured in one piece, for example using a coextrusion process, or it can be composed of two pieces that preferably run parallel to one another.
