Description

The application relates to a sealing device with a sealing strip for sealing bridging a gap between an insertable into a soffit of a building frame and the soffit, wherein the sealing strip along a first in the longitudinal extent thereof extending edge region is connected to the soffit and along an opposite second edge region Einsteckprofil for connecting to the frame, which Einsteckprofil comprises a plug-in part for latching insertion in a correspondingly formed Einstecknut on the frame.

For reasons of thermal protection, it is necessary to seal a frame used in a soffit of a building, for example a window or door frame, against the soffit. For this purpose, the aforementioned sealing device is used. Such sealing devices are arranged circumferentially around the frame and connected on the one hand with the frame and the other with the reveal, so that the gap formed between the frame and soffit is covered by the sealing device and thus sealed.

Sealing devices for sealing bridging a gap between a usable in a soffit of a building frame and the soffit have long been known. For example, the DE 297 15 660 U1 and DE 296 05 456 U1 Such sealing devices.

A sealing device, which is attached by means of a Einsteckprofils the frame is made of DE 198 01 865 A1 known. Another sealing device describes the DE 201 17 273 U1 ,

A generic sealing device, from which the invention proceeds, is in the EP 1 471 202 A2 described. Again, the determination of the sealing means on the frame by means of a male part by insertion into a designated circumferential groove on the frame and the attachment to the soffit by means of an adhesive strip, wherein both the adhesive strip and the male member are respectively formed at opposite edge regions of the sealing strip.

However, all the sealing devices described above have in common that the male profile is connected to the sealing strip by means of an adhesive. Mostly it is a butyl-based adhesive.

The use of such adhesives is undesirable for various reasons. Firstly, the application of the adhesive is time-consuming and at the same time care must be taken that the parts to be bonded together quickly assembled so that the adhesive can still make the connection. In addition, all such adhesives contain solvents that leak in the processing of the adhesive to a considerable degree and can endanger the people employed in the production of the adhesive bond.

Therefore, the invention is the object of the invention to provide a sealing device of the type mentioned, which always ensures a secure connection between the sealing strip and the male profile with technically simple means and yet free from the problems known in the art.

This object is achieved in a sealing device of the type mentioned in the present invention, that the sealing strip is adhesively free connected to the male profile.

The essence of the invention is in the preparation of the desired connection between the sealing strip and the male profile, exploiting the temperature dependence of the physical states of the parts so that an adhesive-free connection can be made by appropriate heat utilization.

One way of producing a compound according to the invention is that the sealing strip is welded to the male profile.

It is possible that the sealing strip is welded to the plug-in part opposite side of the Einsteckprofils with the male profile.

Another possibility is that the sealing strip is welded to the male profile on the side of the male with the male profile. Of course, the welding operations can be carried out on both sides.

A development of the invention provides that the male profile is an extrusion part and has been connected during or after its extrusion with the sealing strip.

Furthermore, it is provided that the male profile integral with the male and female part of a thermoplastic or rubber-like material.

In order for the introduction of the male part is simplified, it is advantageous if the male part protrudes at right angles from one side of the sealing strip with a flat position of the sealing strip. In this flatness of the sealing strip, the male part is opposite the sealing strip at right angles from one side of the same and can therefore be used usually on the frame of windows or doors existing Außenstecksein and secured there latching.

A development of the invention provides that the first edge region has an adhesive strip for connection to the soffit or can be connected to the soffit via a molding compound applied to the soffit.

In order to also on the opposite edge region of the sealing strip, which is not included in the receiving part of the Einsteckprofils to gain reinforcement and possibly stiffening for ease of laying and also in this edge area to reduce the risk of injury by protruding ends of a mesh fabric of the sealing strip, sees a development of Invention, that the first edge region is formed folded double-folded and the adhesive strip is applied in the region of the double-layer Umfalzung.

The sealing strip which lies twice at this edge region as a result of the fold-over is substantially stiffer and can therefore be permanently pressed against the course of the reveal by plastic deformation and adhesively bonded here by means of the adhesive strip or the molding compound.

Depending on the application of erfindungsmäßen sealing device, for example on the inside or outside of a window frame, the sealing strip may consist of a multilayer composite web, which is always waterproof and windproof, but optionally vapor diffusion open or vapor diffusion tight.

Furthermore, it is advantageous if the composite web has a middle layer of a compact film which is arranged between two layers of nonwovens based on thermoplastic materials and adheres firmly to them. Depending on the application of the composite web formed in this way, this middle layer gives the optionally vapor-diffusion-open or vapor-diffusion-proof property with simultaneous water and windproofness.

Furthermore, it is advantageous if the composite web is at least partially equipped with a plastically deformable layer. This makes it particularly easy to adapt to the respective course of the soffit and / or the frame and remains in the once given form permanently.

For this purpose, it is possible that the plastically deformable layer is formed from a plastically deformable metal in the form of a film, a fabric, Geleges, knitted fabric, wires or the like

It is particularly advantageous if the plastically deformable layer consists of a subsequently smooth-rolled expanded metal. This makes it possible to follow even better unevenness on the soffit, without having to spend large pressure forces for it. Furthermore, due to the "fixed" crossing points, large mesh sizes are possible. This leads to a large weight reduction and also to a reduction in material costs. Finally, it is ensured by the subsequent smoothing, that the metal surfaces of the grid no longer have sharp edges that could lead to destruction of the composite web layers. Another special feature of the expanded metal is that the plastically deformable expanded metal adapts almost 100% of the masonry when it is pressed.

According to one embodiment of the invention, it is provided that the plastically deformable layer is formed from a plastically deformable plastic in the form of a film, a sheet or plastic wires. It is also possible that the plastically deformable layer is applied over the entire surface of a middle layer covering layer of a non-woven.

In order to assist assembling personnel in installing the frame with the sealing device, which side should face outwards to the surroundings and which side should face inwards, it is advantageous if it is dyed blue or red. It is intended to have the blue color facing outward to the environment, while the red color should be directed inward towards the warm area.

Since the sealing device often has a plastically deformable layer of a metallic wire mesh, the ends of which may protrude sharp edge in the edge region of the sealing strip, it is advantageous for reducing the risk of injury of the assembly personnel when the male part has a U-shaped receiving part viewed in cross section, in which the edge region of the sealing strip is received under edge-side enclosure, or in cross-section L-shaped, wherein the shorter leg rests against the second edge.

Furthermore, the plastically deformable layer of the composite web can be covered on the outside with a cover layer made of a nonwoven based on thermoplastic materials and adhesively bonded thereto.

In the latter case, the sealing strip according to the invention consequently comprises a composite web of a total of five layers, namely a layer arranged between two nonwoven layers of a compact film, a plastic deformable layer which is applied on one of the nonwoven layers on the side facing away from the compact film , as well as on the outside a further covering layer of a non-woven, which covers the plastically deformable layer on the outside.

Insofar as the layers of the composite web contain thermoplastic materials, they are preferably built on the basis of the same, similar or compatible plastics with each other for the purpose of easier receivability, which are also adhesively bonded together under the action of air and heat by the known methods by laminating or laminating.

Furthermore, the invention also relates to the use of above-mentioned sealing devices prior to their attachment to the soffit as a protective cover of fitting parts of the frame and sash existing and to be used unit, wherein the male part is inserted in the insertion of the frame.

This makes it possible to protect the fittings in the transport of frame and sash unit. Furthermore, the workload when inserting so thus provided frame is substantially reduced by this pre-assembly of the sealing device.

For this purpose, it is advantageous if the first edge region is detachably fastened to the casement frame.

On the one hand, this can be achieved by inserting the first edge region in the glazing rebate of the sash frame, or by releasably adhering the first edge region to the sash frame, or by fixing the first edge region to the sash frame via an adhesive tape.

The layers of the composite web formed from the nonwoven are preferably formed from nonwovens of endless filaments and / or meltblown microfibers based on polyolefins, such as polyethylene or polypropylene or polyesters, for example polyethylene terephthalate or a polyamide. These layers preferably have a basis weight of 10 to 50 g / m ² , preferably 20 to 60 g / m ² .

The middle layer of the composite web of a compact film is formed, for example, based on polyolefins, such as polyethylene or polypropylene or a copolyester in a thickness of 10 to 50 .mu.m, preferably about 25 .mu.m, wherein the sealing strip has a water vapor diffusion density WDD according to DIN EN ISO 572 of 500 to 2000 g / m ² 24h, preferably about 1200 g / m ² 24h, which gives the composite web used the desired water vapor permeability.

Alternatively, the middle layer of the composite web can also be formed from a compact film based on polyolefins or an aluminum thin film in a thickness of 10 to 250 .mu.m, preferably 20 to 100 .mu.m, and the air layer thickness of the sealing strip equivalent to water vapor diffusion is then at least 2 m, preferably at least 5m, and more preferably at least 50m, such that such a composite web is vapor diffusion tight for the inventive sealing strip.

Next measures to facilitate processing provide that the adhesive strip applied along the edge region is covered with a peelable masking tape, which is only removed immediately before the gluing of the sealing strip on the soffit.

A further laying ability can also be achieved by the fact that the sealing strip is wavy deformed at least partially, preferably the wave crests and wave troughs extend transversely to the longitudinal extent of the sealing strip and this give therefore increased longitudinal strain, which makes it easier to lay in corners ,

Advantageous embodiments of the present invention will become apparent from the subclaims 6 to 14.

A sealing strip according to the invention is preferred in which the plastically deformable layer of the composite web is covered on the outside with a cover layer made of a nonwoven based on thermoplastic materials and adhesively bonded thereto.

All layers of the composite web, insofar as they contain thermoplastic materials, are preferably formed on the basis of identical, identical or compatible with one another and adhesively bonded to one another by laminating or laminating under the action of pressure and heat.

The nonwoven layers of the composite web are preferably formed from nonwoven filaments of continuous filaments and / or meltblown microfibers based on polyolefins such as polyethylene or polypropylene or a polyester such as polyethylene terephthalate or a polyamide.

In particular, the nonwoven layers of the composite web have a weight per unit area of 10 to 150 g / m ² , preferably 20 to 60 g / m ² .

The middle layer of the composite web is preferably formed of a compact film based on polyolefins such as polyethylene or polypropylene or a copolyester in a thickness of 10 to 50 microns, preferably about 25 microns, wherein the sealing strip has a water vapor diffusion current density of 500 to 2000 g / m ² 24 h, preferably about 1200 g / m ² 24 h.

The middle layer of the composite web is formed of a compact film based on polyolefins or an aluminum thin film in a thickness of 10 to 250 microns, and the equivalent to water vapor diffusion air layer thickness of the sealing strip is at least 2 m, preferably at least 50 m.

The adhesive strip applied along the edge region of the sealing strip is preferably covered with a peelable masking tape.

Further advantages and features of the invention will become apparent from the following description of several embodiments and from the drawings, to which reference is made.

Various embodiments of the sealing devices will now be described with reference to FIGS. 1 to 7. In this case, the same reference numerals refer to the same features, unless stated otherwise.

FIGS. 1 and 2 show a frame of a window inserted in a soffit 4 of a building, FIG. 2 showing the plan view and FIG. 1 showing the section according to arrows Z-Z in FIG.

The frame of the window consists of a frame 2 and in a conventional manner movable hinged thereto sash 3.

Between the frame 2 and the surrounding soffit 4 of the building a circumferential gap 40 is formed in installation position of the window, which must be sealed. To seal the formed between the frame 2 and the soffit 4 circumferential gap 40, a sealing strip 1 is used, which is arranged circumferentially around the frame 2 and on the one hand with frame 2 and on the other hand connected to the reveal 4, so that the gap 40 covers and is sealed.

As can be seen from the enlarged sectional view according to Figure 1, this is the sealing strip 1 by means of a along an edge region arranged Einsteckprofils 14 anchored and secured in a correspondingly formed circumferential groove 20 of the frame 2 by inserting, while the opposite edge region of the sealing strip 1 mittelts a Adhesive strip 13 is attached to the soffit 4.

The further Ausgesaltung the sealing strip 1 is shown in Fig.4a with reference to a first embodiment.

The sealing strip 1 shown in Figure 4a is formed by a composite web 10, the more detailed structure is illustrated by the enlarged view according to detail X in Figure 3.

3, the base of the composite web 10 initially forms a three-layer composite comprising, for example, an outer layer 100 of a spunbonded nonwoven polypropylene filament having a basis weight of preferably 40 to 60 g / m ² , on which a membrane 101 is arranged as a middle layer of a polypropylene film and in turn a layer designated as inner layer 102 of a protective fleece based on polypropylene fibers with a basis weight of preferably only 10 to 20 g / m ^{2 is} applied.

This three-layered basic composite of the layers 100, 101, 102 already ensures the desired waterproofness and windproofness of the composite web 10, whereby, depending on the desired property of the composite web 10, the layer 101 serving as a membrane made of a polypropylene film is optionally vapor-diffusion-open or vapor-diffusion-tight is what ultimately gives the composite web 10 the corresponding property.

As shown in FIG. 3, a plastically deformable layer 103, for example made of a wire mesh made of soft annealed copper or aluminum, is applied on top of the inner layer 102 made of a polypropylene nonwoven serving as a protective layer. The inner layer 102 serving as a protective layer protects the sensitive membrane 101 from direct contact with the plastically deformable layer 103, so as to prevent possible damage by friction or puncturing of the membrane.

On the other, the upper side in FIG. 3, the composite web 10 has a further nonwoven layer 104, which covers the palely deformable layer 103 on the outside and is formed, for example, from polypropylene fibers having a basis weight of preferably 20 to 40 g / m ² .

All five aforementioned layers 100,101,102,103,104 are adherent to each other, for example, connected by a laminating process.

As a result of the embedded plastically deformable layer 103 of, for example, a wire mesh formed from a thus formed composite web 10 sealing strip 1 can be easily adapted to the course of the frame 2 and / or the soffit 4 and remains permanently in the once predetermined shape.

Particularly suitable is an expanded metal, which has subsequently been smoothed, so that no sharp edges can protrude more.

For connecting the sealing strip 1 produced from a composite web 10 formed in this way with the reveal 4 is at a first edge portion 10a of the sealing strip 1, an adhesive strip 13, for example based on a butyl rubber arranged, which is covered when not in use until just before mounting the sealing strip by means of a removable cover strip 13a, for example based on a plastic film or a siliconized paper. By means of this adhesive strip 13, the sealing strip 1, as shown in Figure 1, permanently adhered to the soffit 4. For this purpose, the sealing strip 1 is applied along the longitudinal axis of the sealing strip 1 extending into the plane of the drawing in FIG. 4a over the entire edge region 10a of the sealing strip 1 extending in this longitudinal extent. This longitudinal extent can be seen from FIG. 2 on the basis of the exemplary axis L.

At the opposite edge region 10b of the sealing strip 1, however, the already mentioned insertion profile 14 is arranged, which serves the attachment of the sealing strip 1 on the frame 2.

For this purpose, the insertion part 14 comprises an insertion part 140 of, for example, a mushroom-like cross-section, which can be latched into the correspondingly formed groove 20 on the blind frame 2 and, moreover, comprises an integrally formed on the insertion part 140 receiving part 141, which in the representation of FIG. Viewed 4a seen cross section has an approximately U-shaped configuration, wherein the opening of the U-shaped cross-section is formed approximately at right angles to the male member 140.

The U-shape of the receiving part 141 of the Einsteckprofils 14 serves to receive the edge portion 10b of the sealing strip 1 under randseitiger enclosure, ie the edge region of the sealing strip 10b is in the receiving part 141 of the Einsteckprofils 14 along the longitudinal axis of the Sealing strip 1 is inserted and secured in this position.

By the peripheral embracing of the edge portion 10b of the sealing strip 1 by means of the receiving part 141 different effects are achieved.

On the one hand causes the edge-side enclosure of the edge portion 10b a relation to the prior art significantly enlarged contact surface between the male profile 14 and the composite web 10 of the sealing strip 1, so that the effected here along the contact surfaces connection between the two parts considerably firmer and thus more durable can be performed ,

In addition, in particular when constructing a sealing strip 1 from a composite web 10 with a plastically deformable layer 103 of a wire mesh there is the danger that sharp-edged cut edges of the wire mesh 103 project from the composite web 10 at the edge. 1, the male profile 14 is pressed with an insert 140, for example, by finger pressure of a mechanic in the intended groove 20 of the frame 2, there is an increased risk of injury to the fitter in this area. Here, the male profile 14 with its viewed in cross-section U-shaped receiving part 141 by the edge-side enclosure of the edge portion 10b of the sealing strip 1 a much higher security, as if necessary. Edge side protruding from the composite web 10 ends of the wire mesh of the plastically deformable layer 103 of the receiving part 141 are reliably covered, so that the risk of cuts and the like is banned in this area.

Finally, the male profile 14 with its U-shaped receiving part 141, viewed in cross-section, offers which the edge portion 10b of the sealing strip 1 is added, also a higher security against damage during assembly of the frame 2.

The usual assembly sequence for mounting a window within a soffit 4 provides that the frame 2 is first arranged in the soffit 4, wherein already at this time the sealing strip 1 on one side, namely by means of its Einsteckprofils 14 on the frame 2 in the in FIG. 1 apparent manner is attached, however, the adhesive connection to the soffit 4 is not yet made. Then, the frame 2 is prefixed within the reveal 4 by setting a desired gap dimension of the circumferential gap 40 by means of wedges, such a wedge is schematically indicated by dashed lines in Figure 1 with reference numeral K. If such wedges K are driven into the gap between reveal 4 and frame 2 to wedge the frame 2 accordingly protects the peripheral edge portion 10b of the sealing strip 1 samtnede receiving part 141 of the Einsteckprofils 14, the composite web 10 of the sealing strip 1 in this area in front of a Damage by the wedge K, so that the sealing effect of the sealing strip 1 is not lost here.

Once the assembly of the frame 2 is completed, then the sealing strip 1 is finally attached by gluing by means of the adhesive strip 13 to the soffit 4 to complete the sealing of the gap 40.

In adaptation to the installation conditions, as can be seen for example in FIG. 1, the insertion part 140 of the insertion profile 14 extends at approximately right angles from one side of the composite web 10 of the sealing strip 1 in the flat position of the sealing strip 1 shown in FIG. Depending on the application, along the opposite edge region 10 a of the sealing strip. 1 the adhesive strip 13 may be arranged on the surface of the composite web 10 facing the insertion part 140, as shown in FIG. 4a, or else on the same surface as the insertion part 140.

An embodiment modified from the exemplary embodiment in FIG. 4 a can be seen from FIG. 4 b, in which the same parts have the same reference numerals and will not be explained again below.

In contrast to the exemplary embodiment according to FIG. 4a, in the exemplary embodiment according to FIG. 4b the edge region 10a of the sealing strip 1, which is equipped with the adhesive strip 13 for connection to the reveal 4, is folded over and therefore the edge region 10a is double-layered, ie. the composite web 10 is arranged here twice over each other. This Umfalzung the edge portion 10a of the sealing strip causes a stiffening thereof, so that a thus formed sealing strip 1 has a higher dimensional stability and can be processed even better. In addition, due to the Umfalzung of the edge portion 10 a, the cutting edge S of the edge region is no longer along the outer edge of the composite web 10, so that if necessary. From the cut edge S protruding ends of the wire mesh of the plastically deformable layer 103 when pressing the sealing strip 1 to the soffit. 4 no longer sharp-edged to produce the adhesive bond by means of the adhesive strip 13 and can lead to injuries, for example, on the fingers of a fitter performing this work.

Finally, according to the illustration in FIG. 4a or 4b, the sealing strip 1 can also be deformed wave-shaped at least in regions in order to give it greater deformability in the direction of its longitudinal extent, which is the laying of the sealing strip 1 in the corner region of the window frame 2 and the reveal 4 relieved.

Of course, the sealing strip 1 described above may also be formed of composite webs 10 having a different layer number and composition, but in any case the male profile 14 with its U-shaped receiving portion 141 and integrally molded male portion 140 provides a substantially improved connection to the composite web 10 and greater protection against injury to a mechanic on the one hand as well as the composite web during assembly on the other.

The male profile 14 is made to provide a preferably integral formation of male member 140 and female member 141 made of a suitable thermoplastic or rubber-like material, for example, this is called the training of PM-MA.

The sealing devices illustrated in FIGS. 5a and 5b differ from those described above primarily by the shape of the insertion part 140. However, the simplest embodiment of a seal is also shown in FIG. 5a. In this case, the receiving part 141 consists only of a rectangular in cross section strips whose one edge terminates with the first edge portion 10b. But it is also possible, which is not shown here, the receiving part 141 seen in cross-section L-shaped design. In this case, the shorter leg serves to cover the second edge 10b in order to achieve an effect at least similar to the insertion profile 14 described above.

In FIGS. 6a and 6b, a possibility for producing the connection between the insertion profile 14 and the sealing strip 1 is shown.

While only a first welding device, which is indicated by the arrow A, is used in FIG. 6a in order to establish a connection, for example by means of ultrasonic welding, according to FIG. 6b, in addition to the first welding device A, a second welding device B is also used the first welding device A opposite side is arranged. Also in Fig.6b, preferably the ultrasonic welding can be applied.

One production method is shown in FIG. Here, the insertion profile 14 is produced by means of an extruder and a tool and fed directly to the plug-in profile via a feed device Z in the vicinity of the tool of the sealing strip 1. The distance from leaving the Einsteckprofils 14 from the tool to the merging of Einsteckprofil 14 and sealing strip 1 depends on the necessary for a sufficiently strong connection temperature of the freshly extruded Einsteckprofils 14 from. This temperature should then have approximately the softening temperature of the sealing strip 1, so that this compound can also be produced. Of course, in order to increase the connection force, the entire sealing device can also be guided by appropriate pressurization devices, such as a pair of rollers.

Furthermore, a sealing device of the above type before its attachment to the soffit 4 also serve as a protective cover of fitting parts of a frame 2 to be used. In this case, the plug-in part 140 is then inserted into the insertion groove 20 of the frame 2. So that then the fitting parts can be protected for example, the transport, the edge portion 10a is releasably attached to the sash frame 3.

One possibility of attachment is then that the first edge portion 10a in the glazing rebate of the sash 3 is plugged in. However, this first edge region 10a can also be detachably adhered to the casement 3. Whereby one possibility can consist of an adhesion band.

These uses are not shown in the drawing.

Also not shown in the figures is another assembly aid, which is to color the sealing device, in particular the sealing strip 1 blue or red. A blue-colored sealing strip 1 should then be directed outwards to the environment, while the red-colored then should be directed inward to the warmer inside.
