Description

[0001] The invention relates to a method for producing a sealing corner for a window, a door or a facade (which may in particular be a unit facade) according to claim 1, to a sealing corner according to claim 10 and to a window, a door or a facade according to claim 11.

[0002] Tubular seals – seals with hollow chambers – are used on windows, doors, and facades to seal a wide variety of gaps, and are also installed in frame corners. To create a sealing corner or even a sealing frame with multiple sealing corners, it is common practice to cut the tubular seal to length, wrap it around one or more corners, and then weld the ends to the frame. A disadvantage is that warping can occur at such sealing corners due to material buildup, which in some cases can even lead to leaks between the seal and the component to be sealed.

[0003] It is also known to cut out the hose seal in sections at the corners of the sealing frame to be manufactured in order to form a sealing corner without unwanted material build-up. The surfaces of the hose seal formed by the cutout are then coated with an adhesive and joined. The adhesive application is not always uniform, thus creating uncertainty regarding the tightness of the resulting sealing frame. A processor who wants to create a sealing frame with sealing corners from a hose seal in this way must exercise great care regarding the adhesive application and precision during the joining process of the respective sealing corners, which can be time-consuming and costly.

[0004] What is therefore desirable is a method for producing a sealing corner for a window or door that is easy to manufacture and yet ensures good sealing even in corner areas where it is to be installed.

[0005] This object is achieved by the method according to claim 1. According to this claim, a method for producing a sealing corner for a window, a door or a facade is provided, which comprises at least the following method steps: a) Providing a hose sealing profile having a hollow chamber, and providing at least one insert or several inserts or providing a foamable agent; b) Making an incision in the hose sealing profile such that the hose sealing profile is not completely penetrated by the incision and at least one web remains between the two profile sections formed by the incision, c) Folding open the incised hose sealing profile in the region of the incision such that, on both sides of the incision, corresponding hollow chamber sections in the two profile sections are accessible with their two cut surfaces; d) At least partially filling the hollow chamber sections; e) Folding together the profile sections at least partially filled in step d) such that the cut surfaces of the hollow chamber sections are placed against one another again on both sides of the incision;f) Making miter cuts, preferably symmetrically to the cut, so that miter cut surfaces are formed, leaving at least one web-like connection between the two miter cut sections of the hose sealing profile formed by the miter cut; and g) joining the two miter cut sections of the hose sealing profile at the miter cut surfaces to form the sealing corner, thereby connecting them to one another.

[0006] In this way, a sealing corner can be produced quickly and easily which does not deviate significantly from the actual cross-sectional contour of the sealing profile in its actual corner area, so that an excellent appearance and very good sealing properties can be guaranteed even in the area of ​​the sealing corner.

[0007] When joining the scrap (g), the two miter cut surfaces can be joined together in a material-to-material bond, particularly by gluing or welding. Both can be implemented easily and simply.

[0008] The process is suitable for hose seals made of a wide variety of materials, particularly for commercially available window, door, and facade hose seals made of EPDM, TPE, or silicone materials, as well as for inserts made of foam materials. The insert(s) can be made of one or more of the following foams: PU foam, PE foam, EPDM foam, sponge rubber, or silicone foam. Alternatively, a corresponding material can be used during the foaming process.

[0009] It is also worth mentioning that the bonding or the adhesive used or the welding process is generally compatible with the foam and / or the seal, with the advantage that the hose seal and foam filling form a good bonding / welding surface and thus a good sealing surface.

[0010] Preferably, the at least partial filling of the hollow chamber sections is carried out simply and uncomplicatedly either by inserting one insert into the hollow chamber of the hose sealing profile, so that the insert engages in the two hollow chambers on both sides of the incision, or by inserting two inserts into the two hollow chambers on both sides of the incision.

[0011] Alternatively, it is also possible that the at least partial filling of the hollow chamber sections takes place by at least partial foaming of the two hollow chamber sections with the foamable agent.

[0012] It is preferred if the insert has a cross-section that completely or substantially corresponds to the cross-section of the hollow chamber. For example, it can be provided that the cross-section of the respective insert is slightly undersized or slightly oversized compared to the cross-section of the hollow chamber.

[0013] The profile sections do not have to be filled with one or more inserts or filled with foam over their entire length - but can be.

[0014] The invention further provides a sealing corner according to claim 10 and a window, a door or a facade with at least one sealing corner according to claim 11.

[0015] Further advantageous embodiments of the invention can be found in the remaining subclaims.

[0016] The invention is described in more detail below using exemplary embodiments with reference to the drawings. The invention is not limited to these exemplary embodiments, but can also be implemented in other ways, literally or in other equivalent ways. It shows: Figure 1a-c: in a) a spatial view of a window or a door; in b) a sectional view of the window or door from Fig. 1a in c) a spatial view of a corner of the sash frame from Fig. 1a or Fig. 1b with a sealing frame and a sealing corner; Figure 2a, b: in a) a sectional view of a section of a facade with hose seals; in b) two sealing corners according to the invention; Figure 3a-h: in a) a hose seal with a drawn-in profile section, in b) the hose seal from a), with a cut-out, in c) the hose seal from b), in whose hollow chamber an insert is inserted, in d) the hose seal from b), in whose hollow chamber two inserts are inserted, in e) the hose seal from c), in whose hollow chamber one or more inserts is / are inserted, in f) the hose seal from c) or d), in the folded-up state with insert or inserts, in g) the hose seal from f) with a miter cut-out, and in h) the hose seal from g) with glued cut-out surfaces, so that a sealing corner is created.

[0017] Several exemplary embodiments are described in the following description of the figures. Individual features of these exemplary embodiments can also be combined with exemplary embodiments not shown and are also suitable as advantageous embodiments of the subject matter described in one or more of the main and subclaims.

[0018] Fig. 1a shows a window. The window has a surrounding frame 1. This is composed of several frame profile members 10 to form a frame shape, in this case a rectangular shape. Preferably, each of the frame profile members 10 is mitered at its respective ends. In the following, the term "window" can be replaced by "door." On a door, the lower of the frame profile members 10 can be replaced by other means (sill) or can be omitted.

[0019] A sash that is movable relative to the frame 1 is arranged on the frame 1. The sash can have a preferably circumferentially closed sash frame 2 and can further have a surface element 3, such as glazing, inserted into the sash frame 2 and received thereby.

[0020] The surface element 3 extends parallel or in a plane extending from the X and Y axes of the coordinate system in Fig. 1a The sash frame 2 is composed of several sash frame profile members 20 to form a frame shape, here also a rectangular shape. Preferably, each of the sash frame profile members 20 is mitered at its respective ends, as shown in Fig. 1c is shown.

[0021] The frame profile members 10 and / or the sash frame profile members 20 can be made of a variety of materials, for example of a plastic or a metal or of wood or of a composite of such materials.

[0022] The sash can be moved relative to the frame 1 from a closed position manually using a handle or motor-driven via a drive into an open position and from there back to a closed position. For this purpose, it is movably mounted on the frame 1 by means of one or more pivot fittings.

[0023] When the sash is closed, a rebate space 4 is formed between the frame 1 and the sash 2, as shown in Fig. 1b The rebate space 4 can be connected to a building exterior I and / or to a building interior II (see Fig. 1a ) must be sealed with a sealing frame 50, as is also the case in Fig. 1c The sealing frame 50 is formed here from a hose sealing profile 51 with a hollow chamber 52. The sealing frame 50 has a sealing corner 100 at each of its four corners, as shown in Fig. 1c is shown.

[0024] In Fig. 2a A section of an exemplary facade is shown in section. The facade here has a support framework 6, onto which a surface element 3 is placed. Here, too, hose sealing profiles 51 are provided, which, as shown in Fig. 2b shown, sealing corners 100 can form.

[0025] For the production of a sealing corner 100 - for example (but not only) for applications of the type Fig. 1 and 2 - the following procedure is specified, which is described in the Figuren 3a bis 3h is shown: In a first method step, the hose sealing profile 51 is provided as a roll or by the meter and one or more inserts 101, 101a, 101b made of a foamed material, such as foamed plastic, as well as a suitable tool for making a cut, such as a knife, are provided ( Fig. 3a Optionally, a cutting template for making a miter cut 54 can also be provided for later process steps. Alternatively, a foamable agent can also be provided.

[0026] In a further process step, the hose sealing profile 51 can be laid out in the form of rolls or by the meter and corner dimensions of the respective frame 1, 2, 6 or the corner are transferred to the hose sealing profile 51 ( Fig. 3b ).

[0027] In a further process step, the hose sealing profile 51 is cut at the respective marked corner - as shown in Fig. 3b shown - an incision 53 is made with a suitable tool - preferably a knife - whereby cutting surfaces 53a and 53b are formed on both sides of the incision. The hose sealing profile 51 is then folded open at the incision 53 ( Fig. 3c ), so that two profile sections 51a, 51b are formed, connected only by a material web, which are only integrally connected to one another in the area of ​​a material web 51c. The incision 53 is preferably made transversely to the longitudinal extent of the hose sealing profile 51.

[0028] The incision 53 is made in such a way that cutting surfaces 53a, 53b are formed on both sides of the incision and in such a way that the hollow chamber 52 or the corresponding hollow chamber sections 52a, 52b created by the incision 53 in the two profile sections 51a, 51b that are formed are accessible from these cutting surfaces 53a and 53b.

[0029] In a subsequent process step, an insert 101 is first inserted at one end into the hollow chamber sections 52a, 51b of the hose sealing profile s51 exposed by the opened incision 53, then bent over a corner and inserted with its other end into the other hollow chamber section 51b (see Fig. 3c , Fig. 3e ).

[0030] Then, in a subsequent process step 500, the hose sealing profile 51 is folded together again with the insert 101 in the hollow chamber 52 ( Fig. 3f ), whereby the insert slips in the two hollow chambers 52a, b until the cut surfaces 53a, 53b of the hose sealing profile 51 are again placed directly against one another.

[0031] An alternative to the step of Fig. 3c is in Fig. 3d shown. After Fig. 3d Not a single insert is bent over a corner so that it engages with its two ends into the two hollow chamber sections 52a, 52b, but rather individual or separate inserts 101a, 101b are inserted into the two hollow chamber sections 52a, 52b until their ends are approximately aligned with the cut surfaces 53a, b. A slight outward projection may remain. Then, in a fifth process step, the hose sealing profile 51 is folded together again with the respective inserts 101 inserted in its hollow chamber 51 (analogous to Fig. 3f ), whereby the inserts can slip slightly until they lie against each other and until the cut surfaces 53a, 53b are again placed directly against each other.

[0032] It should also be mentioned that it is also conceivable that the inserts 101, 101a, 101b are not as in Fig. 3c or 3d shown, are provided as preformed molded bodies or molded profiles made of foam, but that the hollow chamber sections are at least filled with the foamable agent in sections (i.e. over part of their length).

[0033] Then, two mitre cuts are made, preferably at an angle of 85° to 95°, in particular 90°, which therefore preferably each run at an angle of 45° to the longitudinal extent of the hose sealing profile 51 - preferably symmetrically to the previously formed incision 53, so that mitre cut surfaces 54a, 54b ( Fig. 3g ), whereby at least one web-like connection 51f remains between the two mitered sections 51d, 51e of the hose sealing profile 51 formed by the miter cut. One or both of the mitered cut surfaces 54a, 54b are then coated with adhesive, and the section(s) 51d, e of the hose sealing profile 51 coated with adhesive are joined at the mitered cut surfaces 54a, 54b to form the sealing corner. Alternatively, it is also conceivable to weld the coated section(s) 51d, e at the mitered cut surfaces 54a, 54b to form the sealing corner.

[0034] The outer contour of the insert(s) 101 or the foam preferably corresponds exactly or at least substantially to the inner contour of the hose sealing profile 51. The outer contour of the insert(s) 101 or the foam can be provided with an oversize or undersize with respect to the inner contour of the hose sealing profile 50.

[0035] The respective insert(s) 101 or the foam can be designed in different ways. They can be optimized for one or more requirements, such as thermal insulation, sound insulation, fire protection, etc. Depending on the application, a foam with suitable properties is selected. Figuren 3a bis 3h shown - as well as external corners can be produced.

[0036] Overall, the respective sealing corner 100 is simpler and at the same time can be manufactured with high precision and thus process reliability and usually without further rework.

[0037] The process makes it possible to produce sealing frames 50 with sealing corners 100 with inserts 101 or foam in the corners or over the entire length or even individual sealing corners 100.

[0038] When a sealing frame 50 with sealing corners 100 manufactured according to the presented process is used, the geometry of the sealing corner 100 can be slightly squeezed or deformed by contact with a counter sealing surface, thus compensating for unevenness. This also applies to a possible offset of the contours between the respective insert 101 or the respective foam and the hose sealing profile 51.

[0039] The process makes it possible to produce a sealing corner 100 in a simpler, faster, more precise and with better sealing properties than the state of the art. Bezugszeichenliste
