Abstract

The profile rail for attaching an inner facing panel for a door or window opening has a U-shaped profile with one side flange (4) having a glue layer (6) for connection of the rail to the main member. The flange has an abutment lip (7) to engage the main member and its inner face has a seal (8) to engage the panel.

Description

The invention relates to a profile strip for connecting a cladding panel, in particular a soffit panel, to a component, in particular a window or door frame or a roller blind rail, having a U-profile with two side legs and a base leg.

Such a profile strip is for example from the German Utility Model 20 2004 001 172.7 known. This profile strip has a U-shaped clamping profile, consisting of two side legs and a base leg connecting them. Between the two side legs, the cladding plate is inserted, which is clamped by the side legs. For attachment of the profile strip, an adhesive layer is provided on the outside of the base leg, with which the profile strip is glued to the front or visible side of a component such as a window or door frame. To assemble the profile strip is first glued to the frame, after which the appropriately cut trim panel is inserted into the U-profile and is suitably connected to the masonry or a corresponding support structure. The cladding panel can be kept safe due to the two-sided enclosure of its edge portion by the U-profile, on the other hand, after in the known from the said utility model profile strip on the inner sides of the side legs are provided corresponding sealing elements, a seal in the area between the inner side of the leg and the Cladding panel can be achieved, which makes it possible to use such a profile strip in the outdoor area, as a rain-proof and windproof connection is possible.

As described, the known profile strip is placed with the adhesive layer located on the outside of the base leg on the viewing or front side of the frame, resulting in that one side legs, which overlaps the visible side of the cladding panel, is visible in the installed state. This is sometimes not least for optical reasons, not always desired, since this results in no quasi-immediate transition panel plate - component. On the other hand, sometimes also color differences, after such a profile of white plastic is usually extruded, while for example the door or window frame and / or the cladding panel have a different color. In order to enable a color coating, appropriate precautions must sometimes be taken on the lateral side of the side leg, which allows adhesion of the wall paint with which, for example, the soffit lining panel is painted.

The invention is therefore based on the problem to provide a profile strip, which eliminates the resulting from the lateral encroachment of the cladding panel optical disadvantages, and can be used at the same time indoors and outdoors.

To solve this problem is provided according to the invention in a profile strip of the type mentioned that on the outside of a side leg an adhesive layer for lateral attachment of the profile strip on the component and on this side at or near the free leg end projecting stop is provided for application to the component , and that on the inside of this side leg at least one sealing element is provided for sealing engagement with the trim panel.

The profile strip according to the invention is not like almost all known connection profile strips visible or front set up on the component, but to install a provided on the side leg outside adhesive layer on the side of the window or door frame or roller blind rail. About the provided at or very near the free leg end, to the side of the adhesive layer projecting stop the profile strip can be accurately positioned. To attach, the stop must be applied to the visible or front side of the component and then glued to the profile strip. The profile strip thus disappears laterally next to the component, so it is no longer visible after the onset of the cladding panel, except for the very narrow dimensionable positioning stop. About one on the inside of the adhesive layer on the outside Furthermore, a tight contact with the cladding panel is realized, so that in this transition region, in particular when used outdoors by driving rain or wind, a good seal is realized. The strip can therefore be used both indoors and outdoors.

The profiled strip according to the invention thus offers the possibility of being able to arrange it virtually "hidden" and allows it to create an optically outstanding transition between the component and the cladding panel, while ensuring a very good seal between the profiled strip and the cladding panel.

The provided on the inside of the mounting leg sealing element is preferably a sealing tape, in particular a foam or Kompriband, which is optionally slightly compressed when inserting the trim panel, in the mounting position of the trim panel rests and so realizes the desired high seal. The sealing tape, in particular the foam or Kompriband, may have an adhesive coating on its free, the profile inside facing side over which in addition to the non-positive or positive composite and an adhesive bond to the cladding panel can be realized.

Alternatively - or additionally - to a band-shaped sealing element can be provided as a sealing element and a projecting flexible sealing lip, loop or bead, which preferably consists of a relation to the leg material softer, deformable plastic material. This flexible sealing element can readily be produced together with the other profile body in a coextrusion process. When inserting the cladding panel, the sealing lip or the like is deformed accordingly, it applies force or form-fitting and firmly against the cladding panel, thus sealing in a safe way from this transition.

A further alternative embodiment of such a sealing element provides this as a deformable, elastic hollow chamber, which on the inside of the side leg is designed to realize. This hollow chamber can be deformed by the lining panel used, wherein it applies close to the plate. Such a hollow chamber can be formed by means of a molded on the inside of the leg, coextruded material portion of a soft plastic material which limits the chamber volume in conjunction with the leg inside. The section should preferably extend over the entire leg height in order to form the highest possible hollow chamber with a large contact or sealing surface.

In the mounting position as described by the profile strip on the one hand only the attack visible, on the other sometimes provided on the inside of the mounting leg, from the cladding panel usually slightly compressed and deformed sealing element of any kind. To the optics in this, albeit very narrow To further improve the area and in addition to protect the sealing element from contamination, excessive exposure to rain, wind or light radiation, provides an advantageous development of the invention that the sealing element of a arranged at the free end of the leg, overlapped towards the inside of the side leg out web is. This web, which preferably rests itself in the mounting position on the cladding panel, may be flexible and be formed of a soft, deformable material, wherein this soft web can be molded together with the other profile body profile in a co-extrusion process. As an alternative to using a flexible web, it is conceivable that the web is rigid and is formed from the material of the side leg, that is, in this case, no two different plastic materials would be used.

The flexible web may be formed in the form of a sealing lip or preferably a material loop, which preferably rests as stated in the mounting position on the cladding panel and provides an additional sealing effect.

To further improve the seal in the interior of the U-profile, it is expedient, in addition to the inside of the opposite leg and / or to provide at least one further sealing element on the inside of the base leg. As a further sealing element, a sealing tape, in particular a foam or Kompriband, or a projecting flexible sealing lip, loop or bead or a deformable elastic hollow chamber, formed by means of the wall portion of soft material, may be provided. Theoretically, therefore, corresponding sealing elements, for example sealing strips, can be provided on all three inner sides of the legs, which lead to a virtually all-round seal.

The stop is inventively very short, he should have a projecting length ≤ 3 mm, in particular of 1.5 mm. After the stop primarily plays the positioning function, such a short dimension is sufficient, it also offers little visible surface.

Finally, it can be provided that a provided by the adhesive layer with the outside of the side leg, in particular the stop extending Folienanklebesteg is provided, which is connected to the side legs, in particular the stop on a material weakening, a predetermined breaking point or perforation. On this Folienanklebesteg can be stretched after attaching the profile strip on the frame or the rail a protective film, for example, over the window or door, so that it is protected in subsequent work in the Leibbereich. After completion of the work of Folienanklebesteg on the intended separation option in the form of material weakening, the predetermined breaking point or the perforation is separated together with the film. In the assembly position, therefore, even in this embodiment, only the stop as well as possibly the overlap rib is visible.

Fig. 1 shows a profiled strip 1 according to the invention, comprising a profile body 2, which shows a U-profile and two side legs 3, 4 and a base leg 5 has. The side leg 3 is to enable a terminal receiving a cladding panel, which will be discussed below, inclined from the vertical to the base leg 5 out by a few degrees, the angle between the two legs is preferably about 83 °.

On the outside of the opposite side of the leg 3 shorter sized side legs 4 a via a peel strip (not shown in detail) covered adhesive layer 6 is provided with the side leg 4, which is the mounting leg for securing the profile strip 1, to a component can be stuck. At the upper end of the side leg 4, a stop 7, which projects to the adhesive layer 6 having side, provided over which the profile strip 1 can be accurately positioned when mounting on the component.

On the inside of the side leg 4, a sealing element 8 is provided in the form of a foam or Kompribandes 9, which may have on its side facing the profile interior preferably covered by a peel strip not shown adhesive layer 10, but not mandatory.

On the upper side, the sealing element 8 is overlapped by a web 11, which is designed as a flexible material loop 12 in the example shown. The material loop 12 is made of a respect to the other profile body softer plastic material. However, it is possible, the profile strip 1 in a single extrusion step in the context of a coextrusion process in which different plastic materials can be extruded and joined together, produced.

Fig. 2 shows a schematic diagram of a mounting situation. The profile strip 1 off Fig. 1 is attached to a component 13, here by way of example a roller blind rail, on the side surface 14 thereof. For this purpose, the cover strip not shown in detail is first removed from the adhesive layer 6 and then the profile strip 1 on the stop 7, which rests against the front or visible side 15 of the component 13, applied to this. Subsequently, the profile strip 1 is glued to the mounting side legs 4 on the adhesive layer 6 on the side surface 14. If the profile strip 1 is fixed, a cladding panel 16, here a soffit lining panel consisting of a visible plaster layer 17, which is applied to a polystyrene support 18, inserted into the U-profile and fixed there by clamping. The foam or Compriband 9 is optionally slightly compressed, but in any case lies flat against the Leibungsauskleidungsplatte 16 and seals towards this point. The flexible material loop 12 also abuts against the trim panel 16 and realizes a clean, flush transition. The Leibungsauskleidungsplatte 16 itself is, for example, foamed to the masonry 19 through a suitable foaming agent 20 or otherwise secured there. As a cladding panel can be used any plate element, for. As a wooden plate, a plastic plate, a metal plate, a fiber composite plate, etc. and any material combinations.

As can be seen, the profile strip 1 disappears completely laterally between the component 13 and the masonry 19, only the very short-dimensioned stop, which has a length of ≦ 3 mm, preferably of about 2-1.5 mm, being visible, and likewise only 2 - 3 mm wide material loop 12, which overlaps and covers the foam or Kompriband 9, so that it is not visible and additionally protected from environmental impact.

Fig. 3 shows a profile strip 1 ', the profile strip 1 off Fig. 1 equivalent. However, here in extension of the stop 7 'a Folienanklebesteg 21 is formed, which in the example shown on a material weakening 22 (alternatively, a predetermined breaking point or perforation may be provided) with the stopper 7' is connected. At the top there is an adhesive layer 22a, which is also covered here by a peel strip not shown in detail, and on to the protection of the component - be it a roller blind rail 13 as in Fig. 2 or a door or window stick - and other part located in the work area, such as a window or a door, a foil can be glued. To remove after completion of the work, the Folienanklebesteg 21 along the material weakening 22, for example, using a knife or the like cut off.

Fig. 4 shows a further inventive profile strip 23, which also has a profile body with a U-profile shape. The structure largely corresponds to the profile strip 1 Fig. 1 However, instead of the flexible web 11 shown there, formed by the material loop 12, a rigid web 24 is provided, which is formed of the same material as the entire profile body. The rigid web 24 with a length ≤ 3 mm also overlaps the foam or Kompriband 25 and is in the mounting position, as shown in dashed lines, also on the cladding panel 26 at. Otherwise, the execution of the profile strip 23 as well as the attachment process, etc. as described above.

Fig. 5 shows a further inventive profile strip 27, also comprising a profile body with U-shape, which profile strip 27 of the profile strip 1 Fig. 1 equivalent. In addition, however, here another foam or Compriband 29 is provided on the base leg 28, which provides additional sealing of the lining panel not shown in detail to the profile bottom out.

Another embodiment of a profile strip 30 according to the invention shows Fig. 6 , On the side leg 31, in addition to the outside adhesive layer 32, the stop 33 and also here flexible web 34 in the form of material loop 35 two sealing elements 36 provided in the form of sealing lips 37, which - again formed by coextrusion - from a softer material than the side legs 31st consist. The two sealing lips 37 - it may of course be more than two or even only one provided - lie in the mounting position sealingly on the trim panel, but are also overlapped by the flexible web 34. As in Fig. 6 dashed lines, 39 more sealing elements in the form of sealing lips 38 may be formed on the opposite inner side of the leg, which also provide a seal in this area.

Finally shows Fig. 7 a profiled strip 40 according to the invention, in which on the side leg 41, which has the outer adhesive layer 42, the stopper 43 and here again the flexible material loop 44, two sealing elements 45 in the form of sealing beads 46 of compressible, soft material. As shown in dashed lines, corresponding sealing beads 48 may also be provided on the opposite leg 47. At the base leg 49, a foam or Kompriband 50 is provided in this embodiment, which accomplishes the seal towards the bottom.

Further shows Fig. 8 a profile strip 51 according to the invention, which essentially the profile strip 23 from Fig. 4 also corresponds to a U-shaped profile and one on the outside of the in Fig. 8 left side leg 59 provided adhesive layer 58 for lateral mounting. In addition, here at the stop 52 via a material weakening 53 a Folienanklebesteg 54 with an adhesive layer 55, which has a not shown in detail peel, molded, ie the Folienanklebesteg 54 and the stop 52, which merges into the rigid web 56, and the other profile body are made of the same plastic. The rigid web 56 is, as already with respect Fig. 4 described, in the mounting position on the cladding panel, not shown here and overlaps the foam or Kompriband 57th

Fig. 9 shows a further embodiment of a profile strip according to the invention 58. This also has a U-shaped profile body 59, on whose side legs 60, the adhesive layer 61 and the stop 62 is provided. As an alternative to the previously described embodiments, this profiled body does not have a web, but of course this does not necessarily have to be provided in the other embodiments as well. On the inside of the side leg 60, a sealing element 63 in the form of a deformable, elastic hollow chamber 64 is provided, which seals in the assembly position to the trim panel. This hollow chamber 64 is formed by means of an integrally formed on the inside of the leg by coextrusion, a chamber wall forming portion 65 of a softer relative to the leg material, flexible plastic material. The portion 65 extends substantially over the entire leg height, so that a relatively large chamber volume and a large sealing surface, formed from the outside of the flexible portion 65 results.

The finally in Fig. 10 Profile strip 66 shown corresponds to the profile strip 58 Fig. 9 , So it also has a hollow chamber 67, formed by means of a flexible portion 68. In addition, at the upper end of the adhesive layer 69 having side leg 70 in addition to the stop 71, a hollow chamber 67 cross web 72 is provided in the form of a material loop 73.

It should be noted at this point that, of course, all the described embodiments - although not shown - via a Folienanklebesteg, as shown in Fig. 3 and 8 is shown, which can be detachably formed on the stop. Of course it is also possible, instead of in the FIGS. 1 . 3, 5, 6 . 7 and 10 each described a flexible material loop rigid jetty, as he in 4 and 8 is shown to provide, or the rigid web in 4 and 8 to exchange for a flexible loop of material. Furthermore, the local arrangement and the nature of the other sealing elements on the base leg or the second side leg (on the mounting leg is imperative to provide a sealing element) may be chosen as interchangeable and based on the embodiments. Also, each foam or Kompriband be provided with a profile inside towards directed adhesive layer.
