Description

The invention relates to a sealing profile for sealing a gap to be sealed between two elements of a window, a door or facade, in particular for sealing a gap between two relatively movable elements of the window, the door or the facade.

The state of the art in this respect are the DE 295 12 778 and the DE 298 14 787 called.

From the DE 10 2008 046 753 A1 a seal is known, which has a hose portion, on which on a side facing a sealing web side a portion is formed with two hinge portions, which allow a limited buckling of the hose portion. It is provided a pressure ridge, which is supported on a solid connecting web, so that the pressure ridge keeps the free sealing web under load from the hose area away or pushes.

For windows, doors and facades a variety of different seals with different tasks is known. Fig.1 shows a section through an edge region of a window or a door. Evident are a frame profile 1 of a window frame and a sash profile 2 of a sash. The sash is movable relative to the frame. In a fold region 3 between the casement profile 2 and the frame profile 1, one or more seals are arranged. At least one stop seal 10 belongs to these seals. This stop seal 10 is arranged in an overlapping region between a free end of a web 4 of the casement frame profile 2 and a web 5 of the window frame profile 1. It is set here in an undercut groove 6 of the web 4 of the sash frame profile 2. By movements of the wing relative to the frame in an opening and closing of the rotatable and / or tilting wing this stop seal 10 is mechanically (in a manner to be explained in more detail) particularly stressed. In a further undercut groove 7 on a web 8 of the frame profile 1, a further of these stop seals 10 may alternatively or optionally be arranged (not shown here).

Furthermore, at least one center seal 11 is arranged in the middle region of the fold region 3 in the fold region 3. It is also possible to provide a plurality of central seals 11 which each bridge the folding area 3.

On the casement profile 2, a surface element 12, in particular an insulating glass pane, is furthermore held with a glass retaining strip 9. In a gap between a web 32 of the sash frame profile 2 and the surface element 12, a system seal 13 is arranged. This engages with a foot 14 in a groove 15 of the web 32 a.

In addition, a plug-in seal 17 is arranged in a gap between a free web 16 of the glass retaining strip 9 and the surface element 12. This overlaps with a Fußnut 18 the web 16th

The frame and the sash of the window, the door or the facade element can each be designed as a so-called solid element.

For sealing the fold region / space 3 between the glare and the sash, the center seal (s) 11 and / or the abutment seal (s) 10 are usually used. While a system seal 13 is usually loaded statically, approximately at right angles, so occur in these stop seals 10 different dynamic loads.

These loads can, like the movement arrow B1 in the FIG. 2 also be approximately rectangular or act on the stop seal 10 (handle side), or, as the movement arrow B2 in the FIG. 3 also runs at a relatively acute angle or on the stop seal 10 (on the hinge side of the wing). In particular, the oblique dynamic loading of pivoting movements of the wing relative to the frame requires a corresponding rounded shape of the sealing body 19, as can be found in tubular seals or curved sealing lips.

The disadvantage of this is that the erection forces of such seals with a tubular sealing body 19 are very low, so that the known seals Do not adequately seal under load, for example due to wind forces or gap tolerances. If the geometry is simply increased, on the other hand considerable operating forces occur, which are likewise to be regarded as disadvantageous.

The invention has the object to reduce these problems.

The invention solves this problem by the subject matter of claim 1. What is provided is a sealing profile for sealing a gap to be sealed between two elements of a window, a door or facade, in particular for sealing a gap between two relatively movable elements of the window, the door or the Facade, comprising a foot area and a base wall, a sealing body formed on the side of the base wall remote from the foot region, which is designed as a hose region having a chamber, and with a sealing web laterally of the hose region, wherein in the hose region on the side facing the sealing web a section having at least two or more, in particular three, hinge areas is formed, which allow a limited buckling of the hose area on this side in the gap to be sealed, and that a tensile region, in particular a draw web, between the sealing lip and the section with the Hinge oak is formed, which pulls the sealing lip to the hose area at a squeezing the hose area in the gap to be sealed.

Since the hose portion seals the sealing lip in the gap, i. pulls in the compressed state to itself, the sealing effect is optimized and improved in particular at the end - but also on the hose area itself - in a simple manner.

In this case, the sealing profile may be formed as a center seal or as a stop seal for placing in an overlap region between a web of the sash profile and a web of the frame profile. Alternatively, however, the seal may also be designed as a system seal or as a plug-in seal for arranging in a gap between a planar element and the casement or between a planar element and the window frame.

According to a variant, it is expedient and advantageous if an arc section of the hose region, starting from the base wall, extends over more than 90 °, in particular over more than 110 ° of the hose region, into a region above the foot region.

Then it is advantageous for achieving a good sealing effect, when the arcuate portion and the free end of the sealing lip are designed to bear against an abutment on the opposite side of the foot region to be sealed gap.

It is also advantageous if the hose region, on its side facing the sealing lip, has two or more, preferably three, of the joint regions following the arc section.

According to a preferred variant, this is simple to implement in that the joint regions are designed as fold regions in the hose region on its side facing the sealing lip, a first hinge web being formed between the first and second joint region, which forms an acute angle α 1 with the arc segment 80 °. Then, it is easy and expedient if between the second and the third hinge portion, a second hinge web is formed, wherein between the first and the second hinge web an acute angle α2 <80 ° is included and when the second hinge web extends to the base wall and he with the base wall forms an angle α3 <70 °.

In these geometries, it is also advantageous for implementing the invention, when attaching the one end of the pull bar to the second hinge web. This is done preferably and advantageous - but not mandatory - in the middle. Then sets the other end of the pull bar in a central region of the sealing lip between 25% and 85% of the length of the sealing lip. Preferably, the pull bar is dimensioned and arranged such that forms a hollow chamber with a triangular cross-section between the sealing lip, the second wall portion and the pull bar, preferably such that the pull bar in the unloaded state of the seal with the base wall an angle of less than 60 ° includes. This is advantageous because so a good, defined pulling action is given to the sealing lip in the compressed state of the seal. If necessary, the triangle may also be filled with a different material than that from which the seal is made (eg, a softer material or a foam). Alternatively, it is also conceivable that no hollow chamber is provided. In this case, the pull bar is integrated into a train area or designed as such.

In the context of the present invention, a sealing profile is provided, which can be used and used in particular as an abutment seal in the rebate area between the frame and the sash frame. However, it can also be designed as a center seal, plug-in seal or system seal and is therefore multifunctional interpretable. It is dimensioned depending on the gap to be sealed and provided with a suitable foot (Rastfuß or groove).

Advantageous embodiments of the invention can be found in the dependent claims.

FIG. 4 shows a seal 20 which can be interpreted in various ways and therefore can be referred to as a multi-functional seal. Preferably, all contours of the Fig. 4 extend perpendicular to the plane of the Fig. 4 , The seal can therefore be formed as a sealing profile, are cut from the desired seals.
The seal 20 has a foot region 21. This foot region 21 is designed here as a plug-in foot, which can be designed for insertion into an undercut groove in the manner of the grooves 6, 7. The foot region 21 could alternatively also be formed as a groove to form a plug-in seal.

The seal 20 further has on its side facing away from the foot region on a sealing body 19, which is designed as a hose portion 22 and laterally of the hose portion 22 has a sealing lip 23 having a free end.

The hose portion 22 has a chamber 33 inside. This can be designed as a hollow chamber or be filled with a medium, for example with a foam.

The hose region 22 has at the end of or above the foot region 21 a base wall 24 which extends perpendicular to the foot region 21. Starting from a corner and edge region of the base wall 24, the hose region 22 furthermore has an arc section 25 on the side facing away from the foot region 21. The arc section 25 extends over more than 90 °, in particular over more than 110 ° of the hose region 22 into an area above the foot region 21. The arc section 25 serves to bear against an abutment W (FIG. Fig. 5a and b ) on the side opposite the foot region 21 of the gap to be sealed. As already discussed, the seal 20 can be designed and used as a stop seal, center seal, system seal and / or plug-in seal. Essentially, only either the foot region (groove or protruding snap foot) and / or the dimensions of the seal 20 are changed.

The hose region 22 further has, on its side facing the sealing lip 23, two or more, here three, joint regions 26, 27, 28 following the arc section 25. These hinge regions 26, 27, 28 are preferably formed by folding or fold regions in the hose region 22 at its side facing the sealing lip 23. Between the first and the second hinge region 26, 27, a planar first hinge web 29 is formed, which forms an acute angle α1 <90 ° with the arc segment 25 (see FIG Fig. 7 ). Between the second and the third hinge region 27, 28, a second planar (straight) hinge web 30 is formed, wherein between the first and the second hinge web 29, 30 an acute angle α2 <80 ° is included. The second hinge web 30 extends to the base wall 24 and closes with the base wall 24 again an angle α3 <90 °.

The angles α1, α2 and α3 (angles α1, α2, α3: see the sake of clarity Fig. 7 ) are variable or can be reduced in size on the job by, in dependence on the force exerted on the sheet portion 24 in the gap by the abutment (element) W pressure. The joint regions 26, 27, 28 each have joint axes or points G1, G2, G3 (FIG. Fig. 7 ) on. When inserted into the gap to be sealed, the points of articulation G1 and G2 in the tube area 22 move closer to the point of articulation G3 or to the foot area 21 by a distance I1. The seal 20 or its tube area 22 is thus readily compressible.

Between the second planar wall portion 30 between the second and the third hinge portion 27, 28 and the sealing lip 23, a connecting wall is provided, which is designed as a tensile region, here as a draw bar 31. This draw bar 31 is dimensioned and arranged such that a hollow chamber 34 with a triangular cross-section is formed between the sealing lip 23, the second wall section 30 and the draw web 31.

It is particularly advantageous that the sealing lip 23 is connected in a preferably central region (between 25% and 85% of the length of the lip) via this draw bar 31 with the hose portion 22. The pull bar 31 sets at its end facing away from the sealing lip 23 between the hinge portions 27, 28 on the hinge web 30 of the hose portion 22 at.

Fig. 5a shows a cross-sectional view of the seal Fig. 4 in which force acting on the seal forces P1, P2 are shown, which are exerted by an abutment element W. The foot region 21 engages in a groove, for example in the groove 6 of the web 4 on the sash profile 2. In this case, the base wall 24 rests on areas of the web 4 (for example on both sides of the groove 6) and is supported there.

As a result of the forces P1, P2, the hinge angles α1, α2 and α3 decrease. As a result, the pull bar 31 is pivoted in the direction of the base wall 24 and pulls on or over the draw bar 31, the sealing lip 23 with. Fig. 5b shows the seal 20 from Fig. 4 and 5a in a deformed state, as reflected in a gap in the manner of Fig. 1 at a window, door or wing.

Due to the compression of the seal 20, i. at a compression of the hose portion 22 and a depression of the sealing lip 23, the angles α1, α2 and α3 of the hinge webs 29, 30 such that a tensile force is applied to the draw bar 31 and this the sealing lip 23 in the direction of the abutment W and to the hose portion 22 pulls out. The abutment W can be a filling element, a glass pane or a frame part of a corresponding frame (casement frame or frame - wing frame) depending on the location and design.

The seal 20 according to the invention has in the compressed state of Fig. 5b two sealing contact surfaces in the areas A1, A2, so that sets a particularly good sealing effect, without developing too large opposing forces that would complicate the usability of the elements. One sealing region A1 is formed on the abutment W on the outside of the hose region 22 and the other sealing region A2 on the free end of the sealing lip 23.

FIG. 5a, b show the seal 20 according to the invention in the unloaded and loaded condition. Unloaded, the seal initially has two attachment points P1, P2 to the abutment W down, which form with increasing load (surface pressure) more and more than the surfaces A1, A2. In this case, the hose region 22 forms a particularly large stop or contact surface A 1. But also the sealing lip 23 settles slightly flat in the area A2 with additional compression pressure to the abutment W.

The FIGS. 6 to 9 clarify well again the sealing mechanism and function. The tube portion 22 of the seal has the hinge portions / hinge portions 26, 26, 28 whose hinge points (G1 and G2) move towards the base wall 24 with increasing compression ( FIG. 6 ). Overall, the seal on three hinge points G1 to G3, wherein the pivot point G3 is fixed locally / statically on the base wall 24 and thus on the web 4 with the groove 6. The three pivot points G1 to G3 form the three opening angles α1, α2, α3, which decrease bellows-like in the gap to be sealed. As in FIG. 8 and 9 shown here, the pull bar 31 is loaded to train and moves in the direction of movement L1, the sealing lip 23 in the direction of the gap to the abutment W. The sealing lip 23 is pulled by the abutment itself in the direction L3 or rotated in the direction of the angle α3. By the described mechanism with the pull bar or a tensile region, however, the sealing lip 23 is pulled in addition to the initiated by the abutment movement L3 in the direction L2 against the abutment W and rotated (α4) and pulled against the tube portion 22 and rotated (α4), thereby sets a particularly high sealing effect.

The seal of the invention can be made of a variety of materials, provided that they are elastic or at least limited elastic. Preferably, EPDM is used. It is also possible to use "weldable" EPDM (preferably for profiles made of plastic) which has regions made of plastic from a second material. The preferred embodiment consists of EPDM with particularly thin-walled webs.

The cavities / chambers can also be filled with a foamed material according to a variant of the invention. For stabilization or for better thermal insulation, outside areas or further cavities and intermediate spaces can also be foamed or filled with third materials, for example with a foam material. The seal can be used in windows, doors and façade elements made of different materials (wood, aluminum, KS, ..). <B> reference numerals </ b> Frame profile 1 Casement profile 2 folding area 3 Stege 4, 5 groove 6, 7 web 8th Glazing bead 9 stop seal 10 Center seal 11 surface element 12 conditioning seal 13 foot 14 groove 15 web 16 plug seal 17 groove 18 seal body 19 poetry 20 footer 21 hose range 22 sealing lip 23 base wall 24 arc section 25 joint areas 26, 27, 28 hinge webs 29, 30 Zugsteg 31 web 32 chamber 33 hollow 34 joint areas G1, G2, G3 span I1, I2 angle α1, α2, α3 force P1, P2, B1, B2 Abutment (element) W
