Description

The invention relates to a connection profile strip, in particular a soffit connection profile strip.

Such moldings are mostly used to produce a transition between a window or door frame or a roller blind rail and the adjoining wall, with known connection profiles are either plastered, or serve the inclusion of cladding panels or the like. On the one hand to ensure a visually clean transition to the door or window frame, and on the other hand to accomplish a tight transition to prevent, especially when using the profile strip in the outdoor area by driving rain or the like conditionally moisture can migrate into the transition region, is off DE 10 2005 022 826 A1 a connection profile strip is known, in which an existing of a hard plastic material profile body which is formed there with one or more Einputzstegen, on the underside of a soft, elastic plastic material existing and thus deformable portion is formed. The section is formed via an inner and outer web on the underside of the hard profile body, these two webs are connected to each other via a transverse web. The outside in the mounting position web runs pointed with the crossbar in the region of the edge, wherein the underside of the tapered edge portion is free of adhesive coating and the edge itself preferably beyond the adhesive plane over which the bar is attached to the component is located. This results in that the profile strip rests in firm adhesion on the adhesive layer on the frame or rail component, while at the same time the soft edge or the soft edge portion rests firmly, flat and tight on the door or window frame or the rail. After the adhesive layer extends approximately to the edge, the sealing edge portion is held with high force in its contact with the frame or the rail. With such a bar can be a visually highly attractive, at the same time high density and in any case age and weather resistant connection to the door or window frame or the roller blind rail can be achieved.

The flexibility of the soft-elastic portion allows both a deformation of this portion in the vertical and in the horizontal direction, about which any wall or component movements can be compensated. In a horizontal movement of the soft-elastic portion is compressed or stretched relative to the profile body, in a horizontal movement, it is moved almost transversely to the profile body laterally to the left or right. Object of the present invention is to improve a connection profile strip to the effect that an even greater mobility of the soft-elastic portion, in particular in the transverse or horizontal direction, is given.

To solve this problem, the invention provides a connection profile strip, in particular a soffit connection profile strip provided with a profiled body with two side bars and a crosspiece connecting them, as well as one made of a soft plastic material, substantially U-shaped portion consisting of two side legs and a transverse leg connecting them consists, wherein the profile body is inserted into the U-shaped portion and the two side legs are attached to the outside of the side webs, wherein between the transverse web and the transverse leg at least one flexible element is provided, and wherein at least the edge portion in which the transverse leg and the side legs of the U-shaped section lying outside in the assembly position converge pointedly, so that the edge lies in or beyond the plane of an adhesive layer located below the transverse leg.

Unlike in the well-known from the prior art bar is in the terminal strip according to the invention of quasi U-shaped because two side bars having profile body inserted into the likewise substantially U-shaped soft-elastic portion, ie, that the side legs of the U-shaped soft-elastic portion drawn into the area laterally of the side webs of the profile body and secured to the outside thereof. That is to say that unlike in the prior art, the side legs are not formed on the underside of the profile body, but on the outer sides of the side webs. They can thus be made longer at the same height, resulting in greater flexibility and greater deformability, in particular if the two side legs extend at an angle to the respective side web, so run obliquely to the side web. In other words, the side legs virtually protrude away from the respective side web, resulting in an even larger, in particular horizontal, displacement possibility.

In order to give the soft elastic U-shaped portion sufficient stability with high flexibility, according to the invention further provided at least one located between the transverse web and the transverse leg flexible element, which also consists of soft-elastic plastic material as well as the section itself, and which is equally easily deformable. Finally, after the outer side leg of the soft-elastic portion in the mounting position with the transverse leg expires pointed and the edge is in or beyond the adhesive layer, care is taken for a very tight connection.

Although it is possible to allow only the edge portion in the area of the strip outside to taper pointedly or to position the edge beyond the adhesive layer plane, this is of course also possible on the opposite strip edge, d. h., That also the edge portion, in which converge the transverse leg and in the assembled position inside leg of the U-shaped portion, runs out sharply, so that the local edge lies in or beyond the plane of an adhesive layer located below the transverse leg. As a result, a very tight seal is achieved at both edges, so that, for example, a foam adhesive tape adhered to the transverse leg and having the adhesive layer is "sealed" from both sides.

The flexible element, which is located between transverse leg and transverse web, is preferably designed as a loop, which has an elliptical shape and is formed on the underside of the transverse web as well as on the upper side of the transverse leg. The loop shape causes lateral curved connecting portions, which extend from the transverse leg to the crosspiece. This embodiment allows a roll-like movement when the transverse leg is displaced horizontally or parallel to the crossbar, which further the increase in horizontal mobility, especially in conjunction with an oblique arrangement of the side legs of the U-shaped soft-elastic portion, is beneficial. It would also be conceivable, for example, instead of a closed loop to provide two separate connecting webs, which are executed bent, and equally allow a roll-like movement. Furthermore, it is of course possible to perform the flexible element as a simple connecting web, which runs from the crosspiece to the transverse leg, as well as two or more such connecting webs may be provided, which may optionally also intersect.

As already described, the two side legs of the soft-elastic U-shaped section preferably run at an angle to the respective side web, but it is already sufficient according to the invention if only the side leg lying outside in the assembly position runs obliquely.

In a further development of the invention may finally be provided that the profiled body between the side bars or between a side bar and provided on the profile body central web a projecting from the profile body fabric strip and this is fixed to the profile body, preferably soft elastic plastic material is introduced. Such a fabric strip is used for solid embedding and connection to the applied after mounting the bar plaster layer. It is fixed from the hard plastic material existing profile body, including a plastic mass, which is preferably also made of soft-elastic material, so that it can be easily injected in the ingot production in this open profile body chamber serves. Depending on the configuration of the profile body, the plastic compound can either fill the entire area between the two side webs, wherein the fabric strip would then preferably be provided on the side web which is located in the assembly position. It is also conceivable, however, to additionally provide a central web on the profile body, the plastic mass preferably being introduced into the rear open chamber between the rear side web and the middle web in the assembly position, and the fabric web is positioned to extend at the rear side of the middle web.

The elasticity of the plastic compound allows a certain flexibility, if a force acts on the connection region of the tissue and the strip due to component movements, so that the tissue can not be torn off or torn off. The open, the plastic mass-receiving chamber may preferably be undercut via at least one laterally projecting nose, which is integrally formed on a side web or the central web. As an alternative to this mounting option, the fabric strip may be e.g. also be glued by means of a suitable adhesive to a web or other strip section. Alternatively, a fixation by sewing the fabric strip is conceivable as the fabric strip can be firmly connected by welding to the bar.

The adhesive layer, which serves to fix the connection profile strip, can either be applied directly to the transverse limb, but it is also conceivable to use a double-sided foam adhesive tape which is glued to the transverse limb with an adhesive layer, the other adhesive layer serves to fix the strips. As an alternative to applying the adhesive layer or gluing the foam adhesive tape directly to the transverse limb, it is also conceivable to provide a thin strip, preferably made of hard plastic material, to which the adhesive layer or the foam adhesive tape is applied to the transverse limb.

The profile body and optionally the stiffening strip is preferably made of rigid PVC, while the flexible portion and optionally the plastic mass of soft PVC, a thermoplastic elastomer (TPE) or other sufficiently soft or flexible plastic. The profile body and optionally the strip and the U-shaped section and optionally the plastic compound are preferably molded together in a co-extrusion process. For example, it is conceivable in a first coextrusion step to spray the profile body and the U-shaped section together, after which the fabric strip is positioned and the plastic compound is injected, it being possible for all process operations to be carried out in a single coextrusion process step.

Finally, it can be provided that on the outside of the side web lying in the mounting position above the attachment point of the side leg, a Folienanklebesteg is formed. This rupture over a predetermined breaking point web is used to fix a window or the door during the Einputzvorgangs protective film. The Folienanklebesteg is preferably formed slightly below the end edge of the side bar, so that the plaster during plastering of the bar along this side bar can be removed clean and the Folienanklebesteg does not bother.

Fig. 1 shows a component in the form of a window or door frame 1, and a window or door 2 in a conventional manner. On the window or door frame 1, a connection profile strip 3 according to the invention is glued on which a Folienanklebesteg 4 projects to the soffit inside, on which a film 5 for protection glued to the window or door. The profile strip 3 according to the invention further comprises three Einputzstege 6, wherein two are located as side bars outside and one is arranged as a middle web between them. In the example shown here, the Einputzstege 6 are plastered in a plaster layer 7. The basic use of such a soffit connection profile is known in the art and need not be explained in detail.

Fig. 2 shows a first embodiment of a connection profile strip 8 according to the invention, which in the context of a in Fig. 1 shown assembly can be used. It consists of a profile body 9 made of hard plastic material, such as rigid PVC, comprising two side webs, namely a side web 10 lying in the mounting position and a side web 11 lying in the mounting position, both of which are connected to one another via a transverse web 12. Furthermore, a central web 13 is provided. The profiled body 9 is open at the top so that there are virtually two parallel chambers extending into the plane of the drawing. In the in Fig. 2 Chamber shown left between the side bar 11, at the upper end of an inwardly projecting nose 14 is formed, and the central web 13, a fabric strip 15 is arranged, which is plastered into the plaster layer 7. It runs on the inside of the web 13 and is fixed by means of a plastic compound 16, which may be a soft, elastic plastic, for example soft PVC, which is injected as part of a coextrusion process. The chamber is almost completely filled. Fig. 2 further shows an integrally formed on the central web 13, transversely projecting Einputznase 17, which of course other anchoring serving Einputzhilfen can be provided, although not shown in detail.

Furthermore, a Folienanklebesteg 18 is formed on the outside of the side web 10, which can be canceled via a material weakening 19 after completion of the Einputzvorgangs. The Folienanklebesteg 18 has an adhesive layer 20, for example, formed by a foam adhesive tape to which the film can be adhered.

The connection profile strip 8 further comprises a U-shaped section 21, consisting of two side legs 22 (the side leg lying in the assembled position) and 23 (the inner side leg) and a transverse limb 24 connecting the same. The U-shaped soft-elastic section 21 For example, it is made of soft PVC. As Fig. 2 shows the profile body 9 is inserted into the U-shaped portion 21 respectively between the side legs 22, 23 was added. These are molded onto the two outer sides 25, 26 of the side webs 10, 11 and fastened there. Visible are the side legs 22, 23 obliquely to the respective side bars 10, 11, ie, they run obliquely to this point up to the respective attachment points. In the respective areas in which the side legs 22 and 23 converge with the transverse leg 24, ie in the respective edge sections 27, 28, the legs are pointed, so that the respective edge 29, 30 preferably beyond the adhesive plane of an adhesive layer 31, the on a foam adhesive tape 32 which is adhered to the underside of the transverse leg 24, provided and is usually covered with a peelable protective paper lie. This results in that the edges 29, 30 and the adjoining thereto, adhesive layer-free surfaces of the underside of the transverse leg 24 are brought into firm contact with the door or window frame or the like.

Furthermore, a flexible element 33 is provided between the underside of the transverse web 12 and the top of the transverse leg 24, which is part of the section 21 or is integrally connected thereto and designed as a loop 34. It is firmly connected on one side with the slightly inwardly curved transverse web 12 and on the other side in one piece with the transverse leg 24. The loop is hollow and elliptical in shape, so that curved connecting webs form on both sides.

The inventive shape of the elastic portion 21 with its sloping side legs 22, 23 in conjunction with the loop-shaped elastic member 33 allows a very flexible and in both the vertical and in the horizontal direction a large freedom of movement enabling construction, with the relatively large component movements without detachment the bonding or plaster connection can be compensated. Because the relatively long because to just in the middle or over the middle of the respective side surfaces 25, 26 of the side bars 10, 11 tightened mounting position of the side legs 22, 23 and the resulting length and their oblique course allow a considerable horizontal movement, too the bent connecting portions of the loop 34 readily follow roll-off.

Fig. 3 shows a further embodiment of a connection profile strip 8 according to the invention, wherein in this and the following figures as far as possible the same reference numerals for the same parts are used. The structure of the profile body 9 corresponds to the profile body 9 Fig. 2 , the corresponding description is referenced. The flexible U-shaped portion 21 has here two flexible elements 33 in the form of two curved connecting webs 35 which are bent outwardly and equally allow a roll-like movement, as the self-contained loop 34 from Fig. 2 , To stiffen the transverse leg 24 of the section 21 here is a bar 36 preferably made of hard plastic material such as rigid PVC, which is very thin, arranged on the underside of the transverse leg 24, to which the double-sided adhesive tape 32 is glued with its adhesive layer 31. The edges 29 and 30 of the tapered edge portions 27, 28 in the respective connecting regions between the side legs 22, 23 and the transverse leg 24 are here again beyond the adhesive layer plane, so that a firm, tight contact of the respective edge portion 27, 28 is ensured.

Fig. 4 shows a further embodiment of the connection profile strip 8 according to the invention, in which case the structure of the profile body 9 of the Fig. 2 and 3 equivalent. The elastic U-shaped section 21 here also has the two side legs 22, 23 and the transverse limb 24 and the respective edge sections 27, 28, in which the respective limbs converge, with the edges 29, 30. Unlike the previous embodiments, an adhesive layer 31 is applied directly to the underside of the transverse limb 24, ie, the adhesive is applied directly to the transverse limb 24, without the interposition of a foam adhesive tape. It would be equally possible, for example to arrange a hard bar 36 on the transverse leg 24 and apply directly to this adhesive.

Between transverse leg 24 and transverse web 12 extend here two flexible elements 33 in the form of straight connecting webs 37, which are as well as the curved connecting webs 35 integral with the transverse leg 24 and consequently also made of soft-elastic material such as soft PVC. These webs are sufficiently flexible to allow a vertical as well as horizontal movement.

Finally shows Fig. 5 a further embodiment of a profile strip 8 according to the invention, in which case the profile body 9 has only the two side webs 10, 11, wherein on both side webs inwardly projecting lugs 14 are provided. It thus forms only a chamber which is completely filled with the plastic compound 16, which serves to fix the fabric strip 15. The fabric strip 15 extends here in the region of the inner side web 11. The elastic portion 21 is also designed here U-shaped, it has two side legs 22, 23 and the transverse leg 24. However, only the edge portion 27 is made tapered so that its edge 29 beyond the plane of the adhesive layer 31, again provided by a foam adhesive tape 32, is located. The edge portion 28 is ultimately not tapered running, in the mounting position, the edge 30 is not on the component. That is, the foam adhesive tape 32 is "sealed" from one side only.

Between the transverse web 12 and the transverse leg 24 extend here two intersecting connecting webs 38, which form the elastic, flexible elements 33, which allow the component movement.

It should be noted at this point that the described different embodiments are of course not exhaustive. Thus, the various profile body 9 shown as well as the geometry of the possible connecting webs between the transverse web 12 and the transverse leg 24 may also be different. Also, further anchoring options can be found on the professional body or Einputzhilfen be provided. Furthermore, other plastics than PVC can be used.
