Description

The invention relates to a plug-in sealing profile for forming a plug-in sealing arrangement according to the preamble of claim 1 and to a plug-in sealing arrangement with such a plug-in sealing profile according to the preamble of claim 20.

Generic - and also according to the invention - plug-in sealing profiles are pressed into an existing gap between a frame profile such as a glass retaining bead - and a surface element, in particular an insulating glass pane, whereby a plug-in sealing arrangement is formed which seals the gap. During the assembly process, the plug-in seals are simultaneously (in one assembly step) compressed for positioning and for sealing in the end position. For this purpose, special structural designs of the plug-in sealing profile of the plug-in sealing arrangement are required.

Plug-in sealing profiles are to be distinguished in particular from system sealing profiles. These seals have a strong or large-volume retaining foot in common, which is also referred to as the anchoring foot. Usually, the retaining foot of the system seal profile is inserted into an undercut groove of the frame profile in a first assembly step. The system seal profile is then securely anchored. It is only in a second assembly step that the surface element is placed against the system sealing profile like an insulating glass pane, whereby it is compressed into the final sealing geometry.

The assembly process of plug-in seals and system seals therefore differs significantly, in particular also in the number of assembly steps required when assembling the two types of seal.

A well-known plug-in sealing profile shows the DE 42 28 874 A1 . This typical, tubular plug-in sealing profile has - like all plug-in sealing profiles - no retaining foot, but a groove extending perpendicularly to the plugging or insertion direction for securing the position. The seal after DE 42 28 874 A1 is pressed with a base bar into the gap between the insulating glass pane and the frame profile until a bar of the profile engages in the groove of the seal. The plug-in sealing profile compresses only insignificantly during installation in the front visible head area and therefore has a relatively large visible width after installation, which gives a disadvantageous visual impression. The thermal insulation properties of the seal also do not meet current requirements.

From the post-published WO 2013/186071 A1 the following subject is known: a plug-in sealing profile for forming a plug-in sealing arrangement by subsequently inserting and sealing an already existing gap between a frame profile and a surface element, an insulating glass pane, a window, a door or a facade element, with the following features: a C-shaped cross-section, with two nested C-shaped areas - a base area made of a compact material and a foam area made of a foamed material - which in sections adjoin one another or lie on one another, the two areas being produced jointly in the coextrusion process, and in the border area between the base area and at least one hollow chamber is formed in the foam area, with a “lower” or, in the assembled state, “inner” leg of the C-shaped base area of the plug-in sealing profile having a convex radius that extends into a lower or into a fold turned sealing lip opens out, which forms a plug-in area which is first inserted into the gap S when the plug-in seal is inserted.

Another plug-in sealing profile known from the prior art is shown in FIG EP 2 192 333 A1 . This plug-in sealing profile is produced in a co-extrusion process from a foamed and a compact rubber-elastic material, for example an EPDM. The use of a foamed component results in improved thermal insulation properties of the seal. The disadvantage of this plug-in seal arrangement, however, is still the visual impression of the still quite large visible area of the fitted plug-in seal. In addition, relatively large forces are required for plugging in assembly.

The DE 101 00 456 A1 discloses a plug-in seal with hollow chambers.

A generic plug-in sealing profile is from DE 20 2007 016 186 U1 known.

The invention is therefore based on the object of creating a plug-in sealing profile and a plug-in sealing arrangement with such a plug-in sealing profile which gives a slightly disruptive, harmonious visual appearance. In addition, the plug-in sealing profile should be easier to install and still have good thermal insulation properties.

The invention solves this problem with the subject matter of claims 1 and 20. Advantageous embodiments can be found in the subclaims.

According to the invention, the assembly is simplified because the hollow chamber enables easier bending of the sealing profile. In addition, the thermal insulation is particularly optimized by the hollow chamber in connection with the foam. The good fit of the seal and the advantageous appearance should also be mentioned as advantageous in this context.

The geometrical features of the hollow chamber claimed in the subclaims ensure that assembly is particularly simple and that a good fit is ensured in the assembled state.

1 illustrates the situation before or during the assembly of a plug-in sealing profile 1 . The plug-in sealing profile 1 is under the action of compressive forces that act on the plug-in sealing profile during the assembly process 1 are exercised, in the direction X, a gap S with a defined width between one leg of a frame profile 21st and a flat facade element 22nd , for example an insulating glass pane.

Before this insertion process is explained in more detail, the structure of the plug-in sealing profile should first be considered in more detail.

2 shows the plug-in sealing profile 1 of the 1 in the unassembled state. The basic geometry of the cross-section of the plug-in sealing profile 1 is essentially C-shaped, whereby the C-shaped plug-in sealing profile in turn consists of two "nested" C-shaped areas - a base area 1a and a foam area 1b - Exists, which in sections adjoin one another or lie on one another and between which at least one hollow chamber 8th is trained.

The hollow chamber is preferably 8th as a recess in the foam area 1b formed, the hollow chamber 8th to the basic area 1a adjoins.

The - in relation to the C-contour - in the assembled state to the frame profile 21st facing C-shaped base area 1a of the plug-in sealing profile 1 consists preferably of a compact, in particular rubber-like elastic material such as EPDM or another thermoplastic elastomer, whereas the foam area 1b consists of a foamed material such as foam rubber. With regard to the materials, please also refer to the EP 2 192 333 A referenced.

The basic area 1a has a retaining groove on the frame profile side 2 for positioning the plug-in sealing profile 1 in a defined final assembly position on the frame profile 21st on. This holding groove 2 is on the outside of the area facing away from the surface element 1a and is perpendicular to the direction of assembly or perpendicular to the plane of the surface element 22nd open to.

The retaining groove 2 is on one side of a positioning bar 3 limited and on its other side by a locking bar 4th .

The positioning bar 3 is visible after assembly, because it is located on the visible side I on the frame profile web after assembly of the plug-in sealing profile 18th and thus serves, as it were, as a stop for reaching a defined final assembly position.

The locking bar 4th serves in addition on the rebate side II to position the seal in the defined final assembly position of the 3 .

The retaining groove 2 forms the middle area of the frame profile side of the plug-in sealing profile 1 out. "Above" or "towards the outside" is connected to this central area as a visible surface 12 an outer leg 19th of the C-shaped plug-in sealing profile 1 on.

The outer leg 19th , which in the unmounted state of the plug-in sealing profile 1 forms a slightly convex radius, opens into an upper sealing lip 6th which, in the assembled state, extend to the insulating glass pane 22nd extends.

A "lower" or, in the assembled state, "inner" leg 17th the C-shaped basic geometry the plug-in sealing profile 1 has a convex radius that extends into a lower sealing lip or one facing a fold 7th opens out, which forms a plug-in area, which is first inserted into the gap S when the plug-in seal is inserted.

The basic area described so far 1a of the plug-in sealing profile 1 is preferably made of a compact, in particular rubber-like elastic material - such as EPDM.

Inside the C-shaped base 1a of the plug-in sealing profile 1 is the foam area 1b of the plug-in sealing profile 1 arranged, which also has a C-shaped geometry.

In the area of the upper sealing lip 6th arises from the interaction of the upper sealing lip 6th with the one below the upper sealing lip 6th adjoining foamed area a sealing bead 5 . Below the upper leg 19th indicates the foam area 1b a hollow chamber 8th on that in their upper section right on the upper thigh 19th the C-shaped basic geometry made of compact material. The hollow chamber 8th preferably has a triangular cross section, which can also be referred to as V-shaped.

The hollow chamber 8th has three corner areas, two of which are corners at the interface between the base and the foam area 1a and 1b and a corner inside in the foam area 1b .

The in the assembled state to the window or facade profile 21st oriented corner between the areas 1a and 1b preferably has an obtuse angle α> 90 °. Those in the assembled state for the surface element 22nd oriented corner between the areas 1a and 1b preferably has an acute angle β <60 ° and the inside in the foam area in the assembled state 1b The lying corner preferably also has an acute angle β <60 °, wherein a radius can also be formed in this area or is formed here.

This preferred geometry of the hollow chamber 8th has a particularly advantageous effect on the assembly behavior, the seat in the assembled state and on the thermal insulation behavior.

The hollow chamber 8th is through the upper thigh 19th Made of compact material, an expansion web resting against the surface element in the assembled state 10 made of foamed material and a connecting web 25th between the thigh 19th and the expansion bridge 10 limited.

One in the assembled state to the window or facade profile 21st facing connecting web 25th (here on the left) next to the hollow chamber 8th has a holding surface 16 on that with the thigh 19th is connected, which is little deformable in this area. This has the advantage that the leg 19th also with the deformation of the plug-in sealing profile 1 Due to the forces acting during their assembly, even in the compressed state, not toward the visible side I or only slightly / insignificantly in this direction “in the 1 and 2 up "evades.

The connecting web (here on the right) next to the hollow chamber, which is oriented towards the surface element in the assembled state 8th has a connection surface 13 on that of the connection of the connecting web - an expansion web 10 - serves, which is designed so that the sealing lip 6th can move upwards in the event of deformation due to assembly forces.

The expansion web forms 10 a particularly large contact surface in the assembled state 11 to the flat facade element 22nd out.

This geometric and material design of the sealing lip 6th , namely on the frame profile side with a high degree of rigidity and on the side of the flat facade element 22nd (not shown) with a low rigidity or high flexibility, there is a defined deformation of the sealing lip 6th .

The sealing lip 6th is used when assembling the plug-in sealing profile 1 in the compression area 15th - see comparative 1 and 3 - initially compressed, and with further deformation finally down into the hollow chamber 8th in over the kink 14th buckle. This changes the length of the sealing lip in a particularly advantageous manner 6th what from the defined shape and positioning of the hollow chamber in the plug-in sealing profile 1 results.

Due to the deformation of the sealing lip 6th and thus the upper leg 19th the plug-in sealing profile 1 results - see 3 - In the assembled state of the plug-in sealing profile a small visible width 20th (please refer 3 ) of the plug-in sealing profile 1 . The expansion bar 10 provides a permanent sealing effect of the sealing lip 6th safe, as it causes the sealing lip to move upwards and thus a possible sliding of the sealing lip from the surface of the flat facade element to be sealed 22nd (not shown) by the geometric design and positioning of the hollow chamber 8th prevented.

When assembling according to the type of 1 becomes the plug-in sealing profile 1 with the wedge-shaped, as a sealing lip 7th trained plug-in section ahead, in the gap S between the frame profile 21st and flat facade element 22nd pushed in until a Defined final assembly position of the plug-in sealing profile 1 is reached. The plug-in sealing profile is thereby 1 deformed accordingly. The plug-in sealing profile 1 Slides on the frame profile side over a frame profile extending perpendicular to the insertion direction X or perpendicular to the pane surface 21st in protruding frame profile web 18th until this is achieved by the compensating movement of the deformed locking bar 4th the plug-in sealing profile 1 under the frame profile web 18th in the holding groove 2 the plug-in sealing profile 1 clicks into place. The latching of the plug-in sealing profile 1 on the frame profile 21st prevents the plug-in sealing profile from sliding out 1 out of the gap and thus ensures a defined final assembly position of the plug-in sealing profile 1 .

On the side of the flat facade element 22nd strives for the sealing lip 6th the plug-in sealing profile 1 due to the deformation of the sealing lip 6th causing assembly forces upwards, but is due to the expansion web 10 held in position and therefore for defined deformation on the kink surface 14th forced. As a result, the sealing lip hugs itself 6th and the contact surface 11 to the flat facade element 22nd and seals the gap between the two-dimensional facade element 22nd and frame profile 21st from, the sealing force required for this from the defined deformation of the plug-in sealing profile 1 results.

There is therefore a considerable difference in the assembly sequence and in the actual assembly process between a plug-in sealing profile and a system seal:

A system seal is first mounted in a corresponding frame profile over the retaining foot. Then the sealing lip of the system seal is brought into operation by adjusting and positioning a flat facade element in the rebate opening provided for this purpose in the frame profile. The flat facade element is then finally sealed with a corresponding retaining strip, which is usually also provided with a system seal.

By 1 is shown and has been explained above that when using a plug-in sealing profile 1 results in a different assembly sequence than with a system seal. When using a plug-in sealing profile, the flat facade element is first 22nd into the rebate opening provided for this purpose in the frame profile 21st adjusted and positioned. The rebate opening of the frame profile 21st is then closed to the outside with a retaining strip, for example. Between the two-dimensional facade element 22nd and frame profile 21st or retaining bar resulting column are then each with a plug-in sealing profile in a final assembly step 1 locked.

3 shows the plug-in sealing profile according to the invention 1 in the assembled state. Here the visible width has increased 20th significantly reduced compared to the unmounted state of the plug-in sealing profile, so that a harmonious visual impression of the plug-in sealing profile 1 adjusts.

The plug-in sealing profile according to the invention 1 has not only optical advantages compared to the prior art, but is also characterized by a particularly advantageous, simple and process-reliable assembly.

It has surprisingly been found that the thermal insulation properties are better than those of the plug-in seals according to the prior art. The reason for this is the combination of the geometry and materials of the plug-in sealing profile 1 in the inserted or assembled state.

This is in 4th illustrated. The plug-in sealing profile 1 points in the heat flow direction, that is from the frame-side end of the plug-in sealing profile 1 Viewed up to the end of the plug-in sealing profile 1 on the surface element side, four areas A. to D. different texture.

So is one to the profile 21st skillful area A. of the plug-in sealing profile 1 made of a compact rubber-elastic material of relatively high strength for safe assembly. Area B. forms a second foam area, which is made of a foamed rubber-elastic material. Area C. consists of air, which is in a hollow chamber 8th located and area D. forms a fourth foam area, which is preferably also made from a closed-cell, foamed rubber-elastic material.

These four areas are located at the level of the critical area of the profile connection in terms of thermal insulation, which results in the particularly good thermal insulation properties.

The lower leg 19th the plug-in sealing profile 1 is preferably made slotted so that the plug-in sealing profile 1 simply in the corners of a frame profile 21st can be relocated. The defined deformability of the plug-in sealing profile 1 is also an advantage.

5 shows a variant embodiment of a plug-in sealing profile according to the invention 1 . In the 5 The embodiment variant shown has in the lower extension of the frame-side web 17th the C-shaped basic geometry of the plug-in sealing profile 1 another sealing lip 24 on. This results in further improved thermal insulation properties of such an embodiment variant of the plug-in sealing profile 1 because of the additional sealing lip 24 Convection effects are reduced.
