Definitions

  • the invention relates to a window with a ventilation duct according to the preamble of claim 1.
  • Such a window which enables sound-insulated ventilation in a tilted or rotated sash position, is known per se, for example from US Pat DE 10 2016 115 422 .
  • the generic construction has a relatively complicated structure and should therefore be further optimized in this regard and, according to variants, also with regard to various other properties.
  • a window is created, in particular a tilt window, turn window or turn-tilt window or parallel opening window, which has at least the following features: a frame composed of several frame profiles, a casement frame composed of several frame profiles, which has at least one surface element and at least between a closed position and a ventilation position is movable relative to the frame, wherein a circumferential frame rebate space is formed between the frame profiles of the frame and the sash, at least one in at least one of the frame profiles of the frame or in at least one of the frame profiles of the sash formed ventilation channel, the first Having a ventilation duct opening and a second ventilation duct opening, and wherein the casement and the frame are designed to close at least one of the ventilation duct openings in the first closed position, and in the two th position to release both ventilation duct openings of the at least one ventilation duct.
  • At least the at least one frame profile of the window frame or the sash, in which the at least one ventilation duct is formed is designed as a multi-chamber hollow profile that consists entirely or essentially entirely of plastic, in particular the adjacent spaces of the window Walls are made of plastic.
  • Plastic frame profiles for example made of hard PVC, are significantly cheaper than aluminum composite structures.
  • PVC profiles in particular have excellent thermal properties and are also suitable for passive houses if they are appropriately designed with enough hollow chambers interpretable.
  • the "multi-chamber structure” can also ensure very good statics in configurations without reinforcement reinforcement and / or without a reinforcement insert.
  • Partition walls can then be formed or arranged much more easily in plastic profiles than in aluminum profiles.
  • Several hollow chambers are advantageous for sound insulation.
  • An advantageous mass-spring-mass system is formed, with the profile walls forming the mass and the air lying between the walls forming the respective spring in the present case.
  • the profile outer walls can have thicker walls, preferably 2-4 mm.
  • the inner profile walls can only be relatively thin, e.g. 1 - 2 mm. This is beneficial as it does a good job of soundproofing and thermal insulation.
  • Another particularly preferred frame profile, in which the ventilation duct can be formed has hollow chambers of different sizes with inclined partition walls - that is, non-parallel partition walls.
  • the walls are preferably constructed asymmetrically.
  • the points of attachment of the partition walls to other walls - e.g. one or more external walls - are then at different distances from one another. As a result, standing sound waves interfere destructively. Vibrations decrease.
  • Frame profiles whose material has a thermal conductivity of less than 1.0 W / mK are preferably used. This is also advantageous as it makes a good contribution to thermal insulation.
  • all of the multi-chamber profiles of the window frame and / or the sash frame 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 have at least one reinforcement insert.
  • the reinforcement insert can be designed as a metal profile, for example as a tube. It is advantageous if steel pipes, e.g. square pipes, are simply pushed into the PVC profiles and screwed as reinforcement inserts.
  • a reinforcement reinforcement e.g. made of metal, is made in coextrusion with the multi-chamber hollow profile made of plastic.
  • a design with a coextruded reinforcement reinforcement is particularly advantageous. No additional assembly steps are required here. Only a recess in the rebate of the profile for the use of a ventilation cassette may be required. The ventilation cassette is simply clipped into the recess and / or fixed with screws.
  • At least two sealing levels are formed between the frame and the casement in the area of the frame rebate space.
  • At least a first of the sealing planes is formed between the frame and the casement in the area of the frame rebate space in the open state. It can also be advantageously and simply provided that two of the sealing planes are formed by stop seals between the frame and the casement.
  • one of the sealing planes of a central seal between the frame and the casement is formed. It is preferred that the central seal is designed to form the sealing plane remaining in the frame rebate space in the ventilation position and to subdivide the frame rebate space into two frame rebate space sections so that air in the ventilation position between the two frame rebate space sections can essentially only be exchanged through the ventilation duct.
  • center seal is attached to the frame and is in particular in the ventilation position in contact with the sash.
  • center seal is attached to the casement and, in particular, is in contact with the frame in the ventilation position.
  • the center seal can be made in one piece with the "sliding seal” or separately from one another.
  • the heat transfer, sound insulation and tightness (air / moisture) are optimized by the three sealing levels.
  • seals are preferably used in each case, which are inserted and held in retaining grooves.
  • Such seals are relatively inexpensive and, above all, easy to assemble. They can be laid all around without having to be cut in the corners. Due to the arrangement in retaining grooves, the seals can be easily replaced.
  • the seals can preferably also be welded to one another.
  • the stop seals (inside / outside) and the center seal are preferably designed circumferentially, i.e. on four sides of the frame, while the sliding seal / sliding sealing lip (separate or integral with the center seal) only on one side (opposite the tilting axis) or preferably on three sides (except on the tilt axis) is arranged.
  • the center seal can preferably be designed as a lip seal with one or more sealing lips, each of which is relatively thin and flexible.
  • a large-volume, multi-chamber central seal is advantageously not necessary in this way.
  • the seals are advantageously made from a weldable TPE or weldable EPDM. In this way, profiles with inserted seals can be welded to form a frame at the same time.
  • the sliding seal is multi-articulated and has a curved sliding surface which, together with the sliding strip attached to the frame, forms a particularly favorable friction pairing.
  • the surface structures and the material combination are important to achieve an optimal result.
  • the relatively small opening width results in the aforementioned prior art through the closure means, the insulating web.
  • This has only a limited length.
  • the sliding sealing lip closes the gap between the frame and the sash up to the outer profile edge of the sash profile. This results in a larger opening width ("W").
  • W opening width
  • B profile width
  • 50 to 80 mm are preferably achieved.
  • the geometry of the sliding seal, in particular the length of the sealing lip, is also decisive. Overall, therefore, even greater widths are possible.
  • a width of 55 to 65 mm is particularly preferred.
  • a significantly larger number of hollow chambers has a beneficial effect on sound insulation.
  • the central seal has a seal base and a sealing section that is pivotably attached to the seal base.
  • This is preferably designed as a pivotable sealing lip.
  • the sealing section - in particular the sealing lip - can be connected to the sealing base in an articulated manner.
  • the sealing section rests at its free end with a contact sliding section on the frame or on the casement in any case in the area or areas in which a respective ventilation duct is formed. It can then be further provided that the contact sliding section rests against a sliding strip in the ventilation position and thus subdivides the frame rebate space in a sealing manner.
  • a contact sliding section and / or a sliding strip By using a contact sliding section and / or a sliding strip, the friction of the sliding seal on the casement can be reduced.
  • This means material and Surface structures are adapted to each other.
  • the sliding seal preferably has a roughened surface structure on the sliding side.
  • the sliding strip is preferably characterized by a sliding coating.
  • the surface structure can of course also be designed the other way around.
  • the contact sliding section has a roughened surface structure on the sliding side and / or that the sliding strip has a sliding coating or that the sliding strip has a roughened surface structure on the sliding side and / or that the contact sliding section has a sliding coating.
  • the one or more ventilation ducts is / are each formed in a ventilation cassette, which is / are in the frame or sash or . is / are inserted into the respective frame profile or the respective sash profile.
  • the formation of the ventilation duct is significantly simplified because it does not have to be laboriously formed directly in the hollow chamber profiles. Rather, it is sufficient to provide or form a recess there and then insert the preassembled ventilation cassette into the recess, e.g. to snap it into place or clamp it.
  • the respective ventilation cassette can be inserted in a simple manner and preferably not visible to the outside in the closed position into a recess of the respective frame profile or of the respective sash profile facing the frame rebate space.
  • the respective ventilation cassette has the ventilation duct openings and that these are aligned with the frame rebate space. It can particularly advantageously be provided that the ventilation duct openings in the closed state lie completely in the frame rebate space between the stop seals. This does not change the external appearance of the window. The preferred design remains.
  • the ventilation cassettes can be changed very easily in this way. This is required approximately annually in order to meet the requirements for purity (dust, insects, etc.). No specialist is required to replace them.
  • the frame profiles, apart from the reinforcement reinforcements, can be formed from a plastic that has a thermal conductivity of less than 1.0 W / mK.
  • the sash when it is moved from the closed position into the ventilation position, can be moved at least at one point by 50 to 80 mm relative to the frame.
  • the air exchange at 2 PA can be more than 12 m 3 / h (preferably> 14), at 10 PA> 25 m 3 / h (preferably> 28).
  • Synthetic microfibers that are able to filter pollen are preferably arranged in the ventilation cassettes. This is of particular benefit to allergy sufferers.
  • the invention also creates an advantageous method for forming a ventilation duct in a window according to one or more of the claims related thereto, a window frame profile being provided, with a recess facing the frame rebate then being formed in the respective window frame profile in which a ventilation duct is to be formed and that a ventilation cassette is inserted exchangeably in the respective recess of the respective frame profile or of the respective sash profile facing the frame rebate space.
  • a corresponding, corresponding sash can then be inserted into the mounted frame at the place of use after installation in a building opening.
  • the center seal can after the assembly of the ventilation cassette on this and on the rest Frame can be mounted. When changing, it is simply removed again. It is particularly advantageous in each case that the assembly can generally be carried out by an insertion movement parallel to the plane of the pane, which is simple and convenient.
  • this cassette can simply be cleaned and / or changed after opening the window, for example after one or more years.
  • the ventilation cassette can be fixed to the frame in the most varied of ways, in a clamping manner or preferably with a fastening means such as at least one screw. It is also conceivable to change a filter material in the ventilation cassette if the ventilation cassette is provided with such a material.
  • the center seal and the ventilation cassette can also be viewed as separate inventions.
  • the central seal for a window according to one of the related claims then has one or more of the features directed to the central seal in the preceding claims and / or the ventilation cassette for a window according to one of the preceding claims has one or more of the claims features directed towards the ventilation cassette.

Rather, two chambers can form between the ventilation cassette wall and the outside, which chambers are particularly preferably separated from one another by an aluminum wall.
  • FIG. 2a and b is complementary to the construction of the Fig. 1a and b provided to form a further sealing lip 25 on the center seal 18 on the sealing base 20, which in the closed state rests on the sash frame 2, so that even sections of four sealing planes are advantageously formed in the frame rebate space between the frame and the sash frame.
