Description

The present invention relates to a door, a window or a facade element with a sealing system for the rebate according to the preamble of claim 1.

Doors, windows or facade elements of the above type have long been known. An important constructive feature of such doors, windows or facade elements are (usually mitred) profile beams from which the frame and / or the casement is mounted. The profile spars are usually cut to length from composite profiles. From the glare and wing frame beams then a thermally separated profile system for door and window construction with a sealing system in the rebate between the glare and the sash is created.

According to the prior art (and the invention), the composite profiles of the glare and / or casement spars consist of at least one metallic outer profile, additionally preferably a metallic center profile and a metallic inner profile, which are each provided with at least one insulating region reducing the heat transfer, for example one or more plastic insulating bars are connected together.

The gap of the rebate space between the glare and the wing frame (spar) is usually sealed with a center seal (center seal system). Here, for example, voluminous center seals with hollow chambers made of coextruded material are known. Another common type of seal, referred to as a stop seal system, utilizes two relatively small seals on the outer surfaces of the profiles. The thermal insulation of these solutions should be further improved or it should be reduced heat transfer.

Against this background, it is the object of the invention to provide a door or a window or a facade element with a sealing system in the rebate, which ensures a particularly good thermal insulation between the separated by the door or window rooms in the rebate.

The invention solves this problem by the subject matter of claim 1. Thereafter, the sealing system at least one or - and this is particularly advantageous - two pairs of seals, each consisting of a first seal on the frame and a seal on the sash, which together at least one central seal form, which of the rebate sealingly bridges in the closed state of the wing. Each of the two seals is fastened separately with a tongue and groove connection to the respective profile. The two pairs of seals are preferably attached to the blind and / or wing frame spars in each case in grooves of insulating bars.

As a further advantageous feature, at least one of the two seals also has a stopper sealing area. Preferably, this stopper sealing region is provided with a fastening means such as a tongue and groove connection on a web of the wing frame spar (or the frame spar).

Overall, the use of one or two pairs of seals results in a sealing system that may be referred to as a combined single or double center seal and stop seal system. This system realizes a very high density and excellent thermal insulation.

Most preferably, the composite profile system is designed as a "three-shell system", consisting of two insulating zones with double seal pair arrangement. As a preferred material for producing the seals, an EPDM or TPE or a comparable plastic (in different Shore hardness) is used, foamed or unfoamed, with or without a hollow chamber. Multi-purpose seals are also conceivable in which combinations of the materials (foamed or unfoamed) are produced simply or by coextrusion.

All metallic profiles are preferably made as extruded aluminum profiles. Alternatively, the production is also possible from a different material such as steel and / or another manufacturing method.

All insulating webs are preferably made of a plastic material, such as e.g. Polyamide (PA66, PA6, PPA), polyester (PET, PBT), polyolefins (PP) or polyvinyl chloride (PVC), so that each one of a substantial thermal separation between the adjacent metal profiles is achieved.

All insulating bars can - but need not necessarily - have at least one hollow chamber. They can also be summarized in a Isolierstegebene by transverse webs to a kind of parent insulating web.

The insulating webs of Isolierstegzonen can advantageously each lie in a plane. This is advantageous because it ensures a clear structure, but not mandatory.

One, several or all seals of the pairs of seals are used according to a preferred embodiment with a sealing foot in a sealing groove of the insulating bars. This is advantageous because so no protrusion of the insulating bars results in the rebate. But it would also be possible to provide the seals in each case with grooves in a less preferred embodiment, in which then would engage the above pins of the insulating bars.

At least one of the seals of each seal pair has one or more hollow chambers, whereby the heat insulation is additionally improved.

Further advantageous embodiments of the invention can be found in the dependent claims.

The invention also provides a pair of seals of a door, a window or a facade element according to one of claims 1 to 33.

Embodiments of the subject invention are illustrated in the drawings and will be described in more detail below. It shows:

1 a door made up of a sash and a frame;

2 a sectional view of a wing and a frame profile in the closed state of the wing;

3 : a section enlargement of the seam of the arrangement 2 ;

4 : a first seal of a seal pair 2 and 3 ; and

5 : a second seal of the seal pair 2 and 3 ,

1 shows a door 1 containing a pivoting and / or rotating wing with a sash 2 and a frame 3 has, where the wing is hinged with one or more fittings. As an alternative to doors, the present invention can also be used in windows or facade elements or the like.

The frame 3 this door 1 has frame frame spars 4 . 5 and 6 on. The sash frame 2 the wing has a vertical wing frame spar 7 on the handle side and another vertical sash frame spar 8th on the band side. In addition, the sash frame points 2 an upper horizontal sash spar 9 and a lower horizontal sash spar 10 on. The wing frame spars 6 . 7 . 8th are each - here by corner connectors (not shown here) - to the sash 2 put together so that in the sash 2 a filling, such as a glazing can be used (not shown here).

In 2 are a frame spar 4 and a wing frame spar 5 the door 1 shown in section. Between the frame spar 4 and the sash frame spar 5 is a rebate F formed in the manner of a gap. This gap should be bridged sealing.

The frame spar 4 has a first metal profile 11 - A first outer profile - on, with a metallic center profile 12 over at least one or more first insulating bars (aligned parallel here) 13a . 13b connected is. These insulating bars 13a , b between the first metallic outer profile and the metallic center profile 12 form a first Isolierstegzone I or plane in the frame spar 10 out. A second metal profile 14 , another external profile - is with the metallic center profile 12 also via at least one or more second (parallel here) insulating bars 15a , b connected. The insulating bars 15a , b between the second metal profile 14 and the center profile 12 form a second insulating land zone II or plane in the frame spar 10 out. The metal profiles of the frame spar 4 have hollow chambers, which is advantageous for the thermal insulation

In 2 show - as an example - both Isolierstegzonen I . II on the frame spar such Isolierstege 13a , b; 15a , b, whose respective end portions are positively and non-positively connected to an associated groove of the metal profiles.

The other frame beams 5 . 6 the door or the window are preferably exactly like the frame frame spar described 4 built up.

The sash spar 7 has a first metal profile 17 as outer profile. This is at least one hollow chamber here 18 is trained. He also has a second metallic outer profile 19 in which also preferably at least one hollow chamber 20 is trained. Between the two metal profiles 17 and 19 is a third metal profile, a center profile 21 , in which also preferably at least one hollow chamber 22 is trained. Also these metal profiles 17 . 19 . 21 may alternatively be designed without hollow chambers or in each case have a plurality of hollow chambers. The hollow chambers may reduce the heat transfer between the spaces adjacent to the door or the window or the facade element and simply allow the placement of corner joints or the like.

The first metal profile 17 is again with the metallic center profile 21 at least one or more first insulating bars (aligned parallel here) 23a , b connected. These insulating bars 23a , b between the first metallic outer profile 17 and the metallic center profile 21 form a first Isolierstegzone III or plane in the wing frame spar 7 , The second metallic outer profile 19 is with the metallic center profile 21 also via at least one or more second (parallel here) insulating bars 24a , b connected. The insulating bars 24a , b between the second metallic outer profile 19 and the metallic center profile 21 form a second insulating land zone IV or plane in the wing frame spar 7 out.

In 2 has the insulating land zone III of sash profile rail 7 the insulating bars 23a , b on, their respective end sections 25 positive and non-positive each with a groove 26 of the adjacent metal profile (outer profile or center profile) are connected, so that in each case one in particular in the z-direction (see. Coordinate system in Fig.) or in a direction orthogonal to the cross-sectional plane of the composite profile 4 shear-resistant connection between the insulating bars and the adjacent metal profile results. This connection is also referred to below as a shear-resistant connection. It offers a shear strength against the forces occurring as a result of dilatation on a window or door or the like.

In 2 is shown that the insulating bars 24a , b of the second insulating land zone IV of the sash frame spar 7 between the second metallic outer profile and the metallic center profile 21 a separation zone between the insulating bars and the second 19 Form external profile in which a sliding slide allows a relative movement. Alternatively, the separation zone between the insulating bars 23a , b and the other Metzallprofil or external profile and the center profile 21 be educated. The insulating bars 24a , b are in y- and x-direction (relative to the coordinate system in 2 ) positively by a Kederverbindung 27 connected to the second metal outer profile. In this way, a sliding guide is formed. The shear strength in the sliding guide orthogonal to the cross-sectional plane of the composite profile may, but need not go to zero. Such a sliding guide is colloquially referred to as a "non-detachable connection".

The arrangement of the unobstructed connection - here in the Isolierstegebene IV - is to be understood as an example. Alternatively, the unobstructed connection in the Isolierstegebene III or in both Isolierstegebene III . IV be arranged or formed in any other way. It can also be dispensed with a connection without joints, if the problem of Dilatationsausgleichs is solved in another way or not.

The sash profile also has a retaining strip 28 through which the filling, such as a glazing is held.

The Isolierstegebenen I and II of the frame profile and the Isolierstegebenen III and IV of the sash profile correspond to each other.

In the gap or in the rebate F between the Blendrahmenholm and the casement spar further an advantageous sealing system is arranged to seal the gap of the rebate F.

3 shows an enlarged view of the rebate F and the adjacent to the rebate isolation zones of the composite profile system 2 ,

The sealing system in the rebate F between the casement spar 7 and the frame spar 4 has two pairs of seals, each consisting of two seals 29a . 30a respectively. 29b . 30b consist of each one of the two seals on the frame spar 4 and the other seal on the wing frame spar 7 is arranged. In each of the two isolation zones I and II respectively. III and IV in each case one of the pairs of seals, each with two different seals 29a . 30a and 29b . 30b ,

The two pairs of seals are the same, but each have two different seals 29a respectively. 29b and 30a respectively. 30b on. Although the seal pairs are each formed the same in each case. Their arrangement in the rebate space is different.

At the first pair of seals in the first and third insulating zone I . III is the first seal 29a - Which is hereinafter referred to as a seal stop - on the frame spar 4 - and the second seal 30a - Which is hereinafter referred to as lip seal - on the casement spar 7 arranged. In contrast, the first seal - the seal stopper - on the second pair of seals - 29b on the wing frame spar 7 arranged and referred to as lip seal second seal 30b on the frame spar 4 ,

This is advantageous since only two different types of seals are required to form two pairs of seals with two different seals, which simplifies the manufacture and handling.

Each pair of seals forms together between them in the closed state of the wing with a web 59 the wing frame spar or the frame spar almost completely closed sealing chamber 34a , b off. In addition, further advantageous also hiss the seal pairs another sealing chamber 35 educated. Such are in the Falzraum three perpendicular to the door or window (main) level adjoining sealing chambers 34a . 35 . 34b educated.

With the help of the pairs of seals four stop areas A1, A2, A3, A4 are formed in the rebate, which interrupt the gap, which would otherwise form the rebate between the blind and the Flügelrahmenholm in the closed state of the wing.

The two outer stop areas A1, A4 are each between a metal profile of the frame spar 4 or the wing frame spar 7 and one each of the seals 30a . 30b educated. The two other (middle) stop area A2, A3, however, are directly between the two seals 29a . 30a respectively. 29b . 30b formed each seal pair. These four stop areas A1-A4 ensure an excellent reduction of the heat transfer over known solutions.

Such will be advantageous in the closed state of the wing in the rebate F between the two rooms, which separates the door or the window from each other, at least four times prevents direct flow of air. The heat transfer in the rebate space can thus be largely minimized. In addition, the sound transmission through the rebate F is reduced.

4 shows the first seal 29a or b of a pair of seals. This seal is also referred to as a seal stop. The seal stop has a base bar 38 , preferably a retaining foot formed thereon 36 and angled at an angle greater than 60 °, in particular at an angle of 90 ° to the base web 35 extending stop bar 37 on. The base bridge 38 here has two areas of different thickness on both sides of the stop bar 37 on. The holding foot 36 is for latching engagement in a groove F directed to the groove 39 in the respective associated insulating web 13a . 24a educated.

5 shows the second seal 30a , b of the two pairs of seals forming a lip seal. The seal formed as a lip seal 30a , b has a base portion 40 and preferably two mutually perpendicular substantially extending sealing lips 41 and 42 on. The sealing lip 41 forms (in conjunction with the stop bridge 37 the other seal 29a , b) a part of a central seal area 50 off while the more sealing lip 42 at its end as a right angle aligned stop seal area 51 (here with a small hollow chamber 52 ) is trained.

The seal formed as a lip seal 30a , b also has one or preferably in its base portion 40 one or (here) two or more hollow chambers 43 . 44 on. These improve the thermal insulation. The base section has a base bar 45 on, with a fastening means (preferably a sealing foot 46 for locking in a corresponding groove 47 an insulating web) for attachment to one of the insulating webs 22 . 23 is trained. Right-angled to the base bar 45 two side bars extend 48a . 48b , which at their ends in the sealing lips 41 . 42 pass. Between the ends of the side bars 48a . 48b also extends a support bar 48c at an acute angle α to the base bar 45 , This will make the side bar 48a or in the extension of the sealing lip 41 securely supported, preferably at a profile stop web 55 . 56 ,

The stopper sealing area 51 is over a connecting bridge section 49 with the base section 40 (spaced) connected. This facilitates the assembly. The stopper sealing area 51 has here advantageously has a fastening means, with which he on the associated profile stop web either the sash 7 or the frame spar 4 is locked. Preferably, the attachment means is a foot 53 with which he is in a groove 54 of the profile stop bar 55 . 56 is attached

The stopper sealing area 51 one of the two pairs of seals sealingly bridges the gap between the free end of the profile stop web 55 of the frame-spar 4 and the opposite corner of the wing frame spar 7 while the other stopper sealing area the gap between the fine end of the Profilanschlagsstegs 56 of the sash frame spar 7 and the opposite corner of the frame spar 4 closes tightly.

In each case at the level of Isolierzonenmitten the insulating zones I . II respectively. II . IV form the two seals 29a . 30a respectively. 29b . 30b each seal pair together from a center seal. Each of these two center seals consists of one of the stopper sealing lips 41 the second seal 30a , b (the lip seal) and one of the stop bars 37 the first seal 29a , b (the stop seal). In the outer region of the rebate space on the profile spars, one seal zone is sealingly located per seal pair 51 , Finally, there are some more advantageous details of the arrangement of the seal pair or here the pairs of seals on Blend- or wing frame spar 4 . 7 considered.

As in 3 to recognize, is the Basissteg 38 preferably the stop seal each dimensioned such that it in the installed state exactly in a non-undercut groove 57 . 58 fits on the trim or sash profile. That is how this seal sits 29a , b each good and safe on the glare or sash profile.

A correspondingly good fit at the lip seal secure each of the two fasteners, here the support feet 46 and 53 as well as the grooves 47 in the insulating bridge 15a . 23a and the feet 53 in the grooves 54 the profile stop webs 55 . 56 in interaction with the obliquely intervening support bridge. That's the way the poetry sits 30a , b each good and safe on the glare or sash profile.

The other blind and wing frame spars 5 . 6 respectively. 8th . 9 . 10 are preferred - but not mandatory - as described Blend and wing frame spars 4 . 7 of the 2 and 3 along with sealing system, with the seals of the 4 , built up.
