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.
  • the known construction requires relatively large actuation forces when closing the sash. It is particularly disadvantageous that the center seal of the window frame slides rather poorly on the insulating web of the sash frame. Another disadvantage to be mentioned is the relatively small opening width in the ventilation position. The opening width is limited, among other things, by the (short) insulating web of the sash as a sliding surface.
  • the invention is therefore intended to take a different approach and create an optimized window with a ventilation duct.
  • the concept of the window is not too narrow. It comprises elements with a frame and a sash frame that is movable relative to it.
  • the window frame can be designed to be circumferential or not to be designed to be circumferential as in the case of a door. In the sense of this document, a door is therefore also a window.
  • the window can be built into a wall opening of a wall or wall of a building. However, it can also be designed as part of a facade or can be built into such a facade.
  • the frame itself can thus also form part of a facade structure.
  • the contact sliding strip provides a component that is adapted to the one or more seals that are in contact with them.
  • the shape, surface and material of the contact sliding strip can be matched to the one or more seals, so that an optimal sliding and / or rolling process is achieved. This reduces the operating forces at the window to a minimum.
  • the contact slide strip is intended exclusively for the contact of the (sliding) seal arranged on the opposite frame and does not take on any other static function of the sash frame. It is therefore not an integral strip of the casement or frame that makes a significant contribution to its statics or influences it, as is the case with an insulating strip that connects two metal shells. It is true that the contact sliding strip influences the closing and opening forces when the sash is closed and opened, since a corresponding sliding seal is preferably in contact with it and, if necessary, can slide during the opening and closing movement. But this is also one of its tasks and one of its advantages to which it can be specially adapted, unlike bars or profiles that primarily serve other purposes.
  • the contact slide strip has an elongated, web-like, in particular elongated arc-like shape with two ends, one of the ends being fixed to the casement or the frame and the other free end protruding into the rebate space.
  • an additional strip is created for the frame profiles actually present on the sash frame (or the blind 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 - blind frame or Sash frame - to serve to close the ventilation duct at least in the opening and ventilation position of the sash frame relative to the frame.
  • the contact slide bar can also have a different shape.
  • the contact slide strip extends in sections at a distance, in particular at a substantially parallel spacing, to the sash frame, in particular in such a way that the contact slide strip extends in sections parallel to an insulating web of the sash frame, which extends two metal shells of the Sash frame connects together and forms a portion of the rebate space.
  • the advantageous contact slide strip can be used to ensure in a simple manner that the contact slide strip does not have to rest on the insulating web, which is usually made of plastic, which causes the window to open due to the relatively high frictional forces between the insulating web and the one or that would disadvantageously complicate the multiple investment webs. It can also be provided that the contact slide strip extends in sections at a distance from an insulating web of the sash, which connects two metal shells of the sash to one another and forms a section of the rebate space.
  • the contour of the arcuate contact slide strip corresponds to the contour or path that the wing moves 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 sash (on the upper sash profile) when the sash can also be pivoted into a tilt position, for which purpose it can preferably have a horizontal tilt axis in its lower area.
  • the seal which comes to rest in the open or ventilation position and possibly also in the closed position of the window, is designed as a central seal.
  • This central seal can in turn be advantageously designed to subdivide the frame rebate space into at least two frame rebate space sections, so that air in the ventilation position between the two frame rebate space sections can essentially only be exchanged through the ventilation duct, the center seal having a seal base and at least one on the seal base pivotably attached sealing section, which is hingedly connected to the sealing base, the sealing section in any case in the area or areas in which a respective ventilation duct is formed, in the ventilation position at its free end with the contact sliding section rests on the contact sliding strip. Two or more such center seals can also be provided.
  • At least two or at least three sealing planes are formed circumferentially between the frame and the casement in the area of the frame rebate space.
  • One or two of the sealing planes can also be formed by one or more stop seals between the frame and the casement.
  • the center seal is attached to the frame and, in particular, is in contact with the casement in the ventilation position.
  • the contact guide strip is attached to the side on and / or in a corner area of the respective corresponding sash profile. It can also be advantageously 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 slide strip and the contact slide section are coordinated with one another and correspond to one another.
  • the center seal is attached to the frame and the contact slide strip is attached to the casement.
  • the contact slide strip is mounted laterally on and / or in a corner area of the respective corresponding sash profile. It can thus be provided that the contact slide strip is fixed with one of its ends to a metal shell of the sash profile on the side of an insulating web of the sash profile. Because in this otherwise usually unused area of the casement, the means to be provided for fixing the contact sealing strip, such as a groove or the like, can be designed and accommodated.
  • the at least one center seal rests on the contact slide 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 on the contact slide bar in the closed position, but is spaced from it in the ventilation position, so that access to the ventilation duct is released.
  • the one or at least one of the center seals is designed as a lip seal with one or more sealing lips, which are each designed to be flexible. Because in this way, the flexible sealing lips can be used to rest on the contact slide strip that controls the opening movement or not or hardly hinder the closing movement of the sash.
  • the shape, surface and / or material of the contact slide strip and the contact slide section can or are coordinated with one another and correspond to one another.
  • the materials can be coordinated with one another in such a way that the seal with its contact sliding section can slide easily along the contact sliding strip.
  • the contact sliding strip can also consist of an aluminum alloy in sections and a plastic in sections.
  • the sliding seal can preferably also have a roughened surface structure on the sliding side.
  • the contact sliding strip can correspondingly have a sliding coating.
  • the surface structure can also be designed the other way around. It can therefore be provided that the contact sliding section has a roughened surface structure on the sliding side and / or that the contact sliding bar has a sliding coating or that the contact sliding bar has a roughened surface structure on the sliding side and / or that the contact sliding section has a sliding coating.
  • one of the ends of the contact slide strip extends up to an edge or just up to an edge (ie up to less than 10 mm in front of the edge) of the frame profile of the sash on which it is fixed is.
  • the attachment of the sliding strip to the frame profile can be done in a variety of ways, for example by screwing, riveting, clipping, or gluing.
  • contact sliding strips of the sash frame that adjoin one another at corners are connected to one another via corner connector-contact sliding pieces.
  • a circumferential "sliding frame" can be formed on the casement (or window frame), which also ensures good sealing of the ventilation duct in these corner areas
  • the frame profiles can also have multiple shells. You can, for example, have two metal shells and an insulating strip in between, but also a metal shell and a plastic shell. They can, however, also have a five-shell structure or also as plastic profiles that are not multi-shell or single-shell, and these can optionally have reinforcements or the like.
  • all of the multi-chamber profiles of the window frame and / or of the casement 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.
  • 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 (opposite the tilt axis) side 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 contact 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 from 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.
  • 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 one or more ventilation ducts is / are each formed in a ventilation cassette that is / are inserted into the frame or casement.
  • 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 enough to provide or form a recess there and then to insert the preassembled ventilation cassette into the recess, for example to snap it into place or to 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. Provision can particularly advantageously be made for the ventilation duct openings to lie completely in the frame rebate space between the stop seals in the closed state. 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 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.
  • 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 connected in various ways be fixed to the frame, so clamped 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.

  • metal profiles - also referred to synonymously here as metal shells - and one or more insulating bars.
  • an insulating strip which is usually made of plastic.
  • other, further designs are also conceivable, in particular designs with a metal profile plane and an insulating profile plane made of plastic and designs with three metal profile planes and two insulating profile planes.
  • a preferably circumferential frame rebate space F is formed between the 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 casement 2 and the inner circumference of the window frame 1.
  • the respective window of the Fig. 1 or 3 serves to be able to close and open a room opening of a building (not shown here), whereby a room I (for example an area surrounding a building) is separated from a room II (for example an interior of the building).

They can only be formed on one of the corresponding frame profiles of the casement 2 and the window frame 1 (e.g. on the frame profiles opposite a hinge axis) or on several of the corresponding frame profiles of the casement 2 and the window frame 1.
  • Running sides of the window frame also form corresponding gaps in the ventilation position, but these gaps do not have a constant width when they are pivoted open. Nevertheless, in addition to improving the ventilation effect, especially on these sides, ventilation ducts 8 of the type can also be used Fig. 1a and 1b also be trained.
  • the sash frame 2 can - preferably to one side or to an adjoining room II - have a contact web 4 with which it rests in the closed position on the frame 1 directly or via a stop seal 5 attached to the sash frame 2.

Since the center seal 18 blocks the direct transition between the rooms FI and FII, an exchange of air between these rooms FI and FII and thus also an exchange of air between the rooms I and II can only take place through the ventilation duct. This provides a very advantageous combination of a ventilation and a sound insulation effect.
  • air can flow into interior space I through gap SI, frame rebate space section FI, ventilation duct 8, frame rebate space section FII and gap SII.
  • the sound is advantageously insulated, in particular, by deflecting the direction of the ventilation duct.

  • the ventilation duct 8 runs in an approximately U-shape within the ventilation cassette 14 (or even without a ventilation cassette). It extends from the first ventilation duct opening 9 approximately parallel to the surface element 3 into the ventilation cassette 14, then runs approximately perpendicular to the surface element 3, 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 several times the direction of air flowing through. 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 Fig. 3 be provided (see e.g. Figure 3b ) to e), will be explained in more detail below).

  • the geometry of the sliding seal, in particular the length of the sealing lip, is also advantageous. Overall, such relatively large opening widths can be achieved in the ventilation position. A width of 55 to 65 mm is particularly preferred.
  • a significantly larger number of hollow chambers compared to an aluminum composite structure has an advantageous effect in terms of sound insulation.
  • the friction of the sliding seal on the sash frame can be reduced to a minimum.
  • the sliding seal preferably has a roughened surface structure on the sliding side.
  • the system sliding strip is preferably characterized by a sliding coating.
  • the surface structure can of course also be designed the other way around.
  • the inner chamber H7 is preferably not used directly as a ventilation duct, since this is not advantageous for reasons of sound insulation. Rather, two chambers can form between the ventilation cassette wall and the outside, which 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.
  • the contact slide strip 24 can be placed on the seals in terms of 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" so long on the contact sliding strip 24 until they no longer have any contact with the frame profile.
  • Isolation bars are usually very smooth, so that seals tend to adhere to them.
  • a metal in particular aluminum, is preferably used as the material for the contact slide strips 24.
  • the rough surface can be achieved by deep-pore anodizing. Special lacquers that form a slightly rough surface after drying can also be used to create a slightly rough surface.
  • plastics can also be applied or overmolded, which are given surfaces that are well suited for the contact strip,
  • Overmoulding can be implemented, for example, in an extrusion process. It is important that the system sliding strip can be optimally adjusted to the seals. This is not possible with system insulating bars.
  • the function of the ventilation window is given until the seal lifts off the insulating bar. This point limits the opening width.
  • the contact slide strip according to the invention maintains contact with the seal for a significantly longer period of time than was the case in the prior art, whereby a larger opening width can be achieved. Particularly advantageous hold, the contact slide strip extends to the edge of the frame profile and thus enables a larger opening width.
  • the contact slide strip 24 is connected to a side of the frame profile facing the rebate to which it is to be attached.
  • Known connection options such as screws, rivets, clips, gluing, etc. are available for this purpose. It is preferred to attach the contact slide strip to the rebate side of the sash profile 102 close to an edge, in particular to the edge that faces the interior or exterior in this way, a relatively large opening width in the ventilation position can be achieved in a simple manner.
  • Figure 3 shows in a) and in b) to e) in each case a section through two different aluminum composite profile constructions consisting of a frame profile 101 and a sash profile 102.
  • the outer edge of the sash profile, to which the contact sliding strip is to be attached can thus be formed by an outer aluminum profile shell. It is advantageous that the system slide strips can be split into different ones as required Frame profile systems can be used. The strips can also be easily replaced in the event of repairs or wear.
  • the frame profile 101 can - as in Fig.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 web 101c (or several insulating webs) ( Fig. 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 (for example by rolling on 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 sash profile 102 can also each 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 web 102c (or several insulating webs).
  • the first metal shells 101a, 102a can be oriented towards an outside I of a building and the second metal shells can be oriented towards an inside II of a building.
  • An insulating glass pane 103 is inserted into the casement.
  • a center seal 104 and a sliding seal 105 are arranged in the fold F between the frame profiles. They can be attached to the frame.
  • the sliding seal 105 functionally also forms a type of central seal and the central seal 103 a type of contact seal, the latter lifting off the sash when it is opened, which is not the case with the central and contact seal and also with the sliding seal 105.
  • This contact sliding strip 124 is fastened to the sash profile 102 in the area of the outside I. To this extent, it has a fastening end 124 a (which can also be called fastening base 124a or fastening foot).
  • the fastening foot can be designed as a projection which engages in the groove 102d. As an alternative or in addition, it can also be clamped and / or latched there.
  • the fastening base 124a can thus be inserted into the groove 102d of the sash 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 tightly with a screw.
  • the contact slide strip 124 protrudes slightly into the fold F in the direction of the frame profile 101 and then extends at a distance from the insulating web 102c of the sash profile next to it in the direction of the second metal shell 102b of the sash frame 102, but does not touch it.
  • the system sliding strip has the Figure 3b ) to e) at its end a cable receiving groove 134 in which a cable 135, for example a cable 135 with one or more electrical and / or optical conductor (s), can be held, for example by latching.
  • a cable 135, for example a cable 135 with one or more electrical and / or optical conductor (s) can be held, for example by latching.
  • the cable receiving groove can be formed on the insulating web 102 c) of the sash profile 102.
  • the cable 135 is held well in the cable receiving groove 134 and is protected from damage towards the fold by the contact slide strip 124.
  • the contact slide strip also forms a cable retaining strip here, which significantly simplifies the laying of a cable on the sash frame. In the case of a reverse construction with a contact slide strip on the frame, the laying of a cable on the frame is simplified accordingly (not shown).
  • the contact slide strip 124 protrudes in the rebate over the insulating web of the sash, but advantageously does not rest on the insulating web in thermal terms, so that a gap X can preferably even form in sections towards the insulating web.
  • the contact slide strip 24 can be resiliently deformed in order to evade the forces acting, in particular when opening and closing the sash. This advantageously reduces the operating forces when opening and closing the sash.
  • the contact slide strip 124 can, in preferred configurations, protrude up to approximately the center of the insulating web 102c. But it can also be designed longer. It is preferably designed in such a way that in the open position of the sash at least one of the two seals 104, 105, in particular the sliding seal 105, is in contact with it (similar or analogous to FIG Figure 1b ).
  • the ventilation duct 8 is again formed in one or more ventilation cassettes 14, which are each inserted into a recess 13, in particular into a cutout that is in the frame 1 (or the casement 2), for example, continuously or starting from Frame rebate space is formed, with a ventilation cassette 14 preferably being used in this milled recess.
  • the recesses 13 are preferably formed in such a way that the insulating webs 101c are completely removed in this area - possibly except for the foot areas in the receiving grooves 101d of the metal shells. If necessary, parts of the receiving grooves 101d are also milled away without damaging the hollow chamber plane from the hollow chamber or chambers 101e.
  • the ventilation cassette 14 takes over the thermal insulation instead of the insulating bars.
  • a ventilation duct 8 On the respective frame side on which a ventilation duct 8 is formed, it does not have to extend over the entire length of the respective frame section / frame spar.
  • one, two or more ventilation cassettes can be provided on one side of the frame, each of which is provided at a distance from one another, so that the cuts of the Figure 3b ) and c) on the one hand and 3d) and e) on the other hand.
  • Several 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 e.g. 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 system sliding strip 124 in section.
  • the sliding strip 24 is designed as an elongated web-like element. It extends perpendicular to the image plane like a profile strip. One of its ends - the attachment end 124a - is designed to be fixed to the sash. From there it protrudes into the fold between the sash frame 2 and the frame 1.
  • the upper side of the contact sliding strip 124 - that is to say here the side facing the frame 1 - serves as a contact and sliding surface for the seal 105 - which has therefore already been referred to synonymously as the sliding seal.
  • the contact slide 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 and sliding seal 105 rests or slides during the opening or closing process of the sash, is also referred to as sliding surface 126.
  • This sliding surface 126 can advantageously be adapted to the pivoting radius of the wing, so it can form a curved surface (large radius). It can also be coated.
  • the fastening area B1 of the contact slide strip 124 is located on the left-hand side facing the outside I.
  • This area B1 can be designed in different ways.
  • a configuration as a clip connection for connecting to a corresponding clip element on the sash profile is particularly advantageous. Is shown in Figure 4a but again a fastening area B1, which is designed for a screw connection. To connect, the contact slide strip 124 is placed on the sash profile 102 and screwed there.
  • this fastening area B1 is preferably about 1/3 of the total width of the contact slide strip 124. That is, 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 resilient effect is achieved, but the area B2 does not become too unstable.
  • Figure 4b shows an alternatively designed contact slide strip 124. This has a first slide surface 126 and a second, somewhat offset slide surface 126 '. The shoulder creates a particularly suitable contact surface for a center seal 104. In addition, this variant is characterized by a hollow chamber 129.
  • Figure 4c shows a further embodiment of the contact slide strip 124 according to the invention.
  • the slide surfaces are not designed in an arc shape but rather as flat surfaces or bevels.
  • the plant sliding strip 124 of the 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-contact-sliding pieces 130.
  • the corner connector system sliding pieces 130 are used to connect the system sliding strips 124 of the various frame spars of a casement across corners.
  • the corner connector-contact-sliding pieces 130 can have two legs 130a, 130b which are aligned at an angle to one another and which, in terms of their nature can correspond to adjacent contact slide strips 124 in each case.
  • 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 system sliding pieces 130 and the system sliding strips 124 are provided with corresponding latching means and / or positive locking means - for example designed as grooves 127 and lugs 131 - which support the corner connector system elements abutting one another in the axial direction Connect sliding pieces and system sliding strip 12 in the direction of the longitudinal extension of the frame spars. In this way, the corner connector system sliders 130 are held securely.
  • the corners can be made rounded by the use of corner connector-contact-slide pieces 130. This is advantageous for the installation of the sliding seals on the installation sliding strips. The advantage is that the compressive forces of the seals are balanced in this area, as described above.
  • the sliding seal or sliding seal 105 must here perform strong changes in shape, but may 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 considerably reduced and a largely optimal contact situation is established.
  • the respective contact sliding strip 124 consists of two areas 124 'and 124 "or sections made of different material.
  • One area 124' can consist of plastic and the other area 124" of a metal such as aluminum.
  • This contact sliding strip 124 which consists of two material areas, can be manufactured in one piece, for example using the coextrusion process, or it can be composed of two pieces that preferably run parallel to one another.
