Description

[0001] The present invention relates to a profile connection comprising a first profile and a second profile arranged at an angle to the first profile, which second profile has at least one hollow chamber into which a web of a connector is inserted.

[0002] DE 203 16 758 U1 discloses a corner connector with two legs, each of which can be inserted into a hollow chamber of a profile. A thin plastic cover is provided on opposite sides of the corner connector, covering the hollow chambers of the molded body. However, the forces exerted by the profiles are absorbed by the metallic molded body. Although the two profiles are securely connected to each other via the corner connector, a comparatively large heat flow occurs when there are thermal differences between the profiles.

[0003] DE 20 2020 100 287 discloses a T-connection on two frame members, wherein a first connector of a non-angular design and a second connector of an angular second design are provided, which are used to connect the two frame members. The assembly of two separate connectors to create a T-connection on the two frame members is comparatively complex, since the two connectors must be aligned accordingly during assembly.

[0004] DE 10 2017 217 183 B3 discloses a corner and / or butt joint in which two partial profiles are connected to each other via two elastic, thermally insulating webs. The elastic webs compensate for manufacturing tolerances and material stresses. Each partial profile is provided with screws or bolts inserted into bores.

[0005] It is therefore an object of the present invention to provide a profile connection which enables a stable fixation of two profiles to one another and ensures good thermal insulation.

[0006] This object is achieved with a profile connection having the features of claim 1.

[0007] The profile connection comprises a first profile and a second profile arranged at an angle to the first profile, which second profile has at least one hollow chamber into which a web of a connector is inserted. The connector comprises at least one insulating web made of a heat-insulating material, which is firmly connected to the web. As a result, the connector is made of at least two materials and can enable optimized thermal insulation, wherein the insulating web is firmly connected to the web and there is less heat flow along the insulating web than at the web. The web can be used to transfer mechanical loads, while the insulating web is arranged, for example, in the direction from the outside to the inside in order to improve thermal insulation. The connector is formed in one piece and can transfer mechanical loads from the web to the insulating web, which is preferably made of a dimensionally stable plastic.

[0008] The insulating bar is preferably oriented substantially perpendicular to the web. The longitudinal direction of the web and the insulating bar are oriented at right angles.

[0009] The connector preferably has a first web, which is inserted into a first hollow chamber of the second profile, and a second web, which is inserted into a second hollow chamber of the second profile. The first web and the second web can be connected to one another via the insulating web, so that the connector is essentially U-shaped. The first web and the second web can each be made of metal, while the insulating web is made of plastic. The first web and the second web of the connector are preferably aligned essentially parallel, so that stable support of the second profile is enabled. Connecting the two webs via the insulating web ensures easy handling during assembly, since only a single connector needs to be positioned on the first profile.

[0010] For easy installation, the connector is clamped to the first profile. This allows the connector to be pushed or slid onto the first profile and is held in place by a clamp. The elasticity of the insulating strip can be used to deform and clamp during the installation process. Optionally, an elastic element, such as a round cord, can be provided on the connector. This can be clamped between the first profile and the connector for pre-fixing.

[0011] For optimized thermal insulation, the first profile and / or the second profile can have an outer profile and an inner profile, preferably made of metal, which are connected to one another via a heat-insulating central profile. The first and second profiles can preferably have such a multi-layer structure, wherein the connector is then preferably fixed with a first web in the region of the outer profiles and with a second web in the region of the inner profiles, while the insulating web and the heat-insulating central profile each overlap in a direction from outside to inside, so that increased thermal insulation is provided both in the region of the first and second profiles and in the region of the connector.

[0012] For easy assembly, a web of the connector can engage with a first retaining section in a first groove of the first profile, and a second retaining section of the connector can engage with a second groove of the first profile. This allows the connector to be positioned on the first profile via the two retaining sections, increasing the strength of the connection. The connector can then be mounted on the grooves on an outer side of the first profile, for example, by sliding or pivoting the connector in.

[0013] The connector preferably comprises at least one web produced by extrusion. The first web and the second web are preferably produced by extrusion and connected to the insulating web, preferably by forming the metallic webs of the connector, which may have deformable fixing webs that are then pressed against a retaining contour of the insulating web. This allows the webs and the insulating web to be initially produced separately and then connected to one another to form a single unit. The extruded webs may have hollow chambers to produce the connector with a low dead weight. The hollow chambers in the webs preferably extend parallel to the longitudinal direction of the first profile and perpendicular to the longitudinal direction of the second profile.

[0014] The profile connection is preferably designed as a T-connection, in which the first profile is connected to a second profile in a central section, with the second profile being connected to the first profile at one end via the connector. Instead of a T-connection, the profile connection can also be used for a corner connection or at a junction with multiple profiles.

[0015] The profile connection is used in particular in frames for windows, doors or facades, for example in a post-and-beam construction or an element facade.

[0016] The invention is explained in more detail below with reference to several drawings. They show: Figure 1 shows a schematic view of a profile construction for a window; Figure 2 shows a sectional view through a first profile and a second profile for a profile connection; Figure 3 shows a perspective view of a connector for a profile connection; Figure 4 shows a view of the connector of the Figure 3 after assembly on a first profile, and Figure 5 a view of the connector of the Figure 4 when installing the second profile.

[0017] A facade construction 1 comprises a frame with two vertical mullions 2, which are connected to each other via horizontal transoms 3. A central mullion 4 is mounted in a central region of the transoms 3. A dividing transom 5 is fixed between the right mullion 2 and the central mullion 4, above which a window 6 is arranged. In such a facade construction 1, the mullions 2 and the transoms 3 can be formed by profiles that are connected to each other in the corner region via a profile connection according to the invention. Furthermore, the central mullion 4 is connected to the transoms 3 via a T-connection, and the dividing transom 5 is butt-connected to the mullion 2 and the central mullion 4. The profile connection according to the invention can also be used with such a T-connection.

[0018] In Figure 2A cross-section through a first profile 10 or a second profile 30 is shown, which can be used in a later window construction as mullions 2, transoms 3, central mullions 4, or dividing transoms 5. The profile 10 comprises a metallic outer profile 11 and a metallic inner profile 12, which are designed, for example, as extruded aluminum profiles. Between the outer profile 11 and the inner profile 12, one or more heat-insulating central profiles 13, preferably made of plastic, are provided. A heat-insulating strip 14 made of foamed material is arranged between the two central profiles 13.

[0019] A groove 16 is formed on the outer profile 11, with a groove wall extending on an outer side and being significantly longer in the form of a web 17, on which an angular retaining web 18 is formed on the inner side. An undercut groove 15 formed by angular webs is formed on the inner profile 12. In the sectional view, the groove 15 is formed on both an upper side and a lower side, similar to the groove 16 and the web 17, so that the first profile 10 is mirror-symmetrical to a central plane.

[0020] The second profile 30 preferably has the same cross-section as the first profile 10, but can also be configured differently. The second profile 30 has a hollow chamber 35 on the outer profile 31 and a hollow chamber 34 on the inner profile 32.

[0021] In Figure 3a connector 20 for a profile connection according to the invention is shown. The connector 20 has a first web 21 or leg and a second web 22 or leg, which are aligned essentially parallel and are connected to one another via an insulating web 23. A holding section 24 is formed on the second web 22 and can be inserted into an undercut groove. Furthermore, at least one hollow chamber 27 is formed on the second web 22, which, in the assembled position, extends parallel to the first profile 10, into whose groove the holding section 24 is inserted. At the tapered transition between the holding section 24 and the web 22, a round cord 37 is inserted, preferably made of an elastic material, in order to enable a clamping fixation of the connector 20 to the groove 15. This allows the connector 20 to be pre-fixed during assembly and is secured against slipping.

[0022] The first web 21 also comprises at least one hollow chamber 28 and has an angular retaining web 26 on an outer side. The two webs 21 and 22 are preferably produced by extrusion, for example in the form of extruded metal profiles, which are then connected to an end section of the insulating web 23 via fixing webs 29. The fixing webs 29 can be bent for fixing to the insulating web 23, for example by roll forming.

[0023] In Figure 4The connector 20 is shown in a pre-assembled position on the first profile 10. The holding section 24 is inserted into the undercut groove 15 of the inner profile 12, and the holding section 25 is inserted into the groove 16 on the outer profile 11. The distance between the grooves 15 and 16 can be dimensioned such that the connector 20 is inserted into the grooves 15 and 16 by a slight deformation with the holding sections 24 and 25, wherein the deformation is achieved, for example, via the insulating web 23 by bending, so that the connector 20 is held clamped to the first profile 10, which facilitates assembly and prevents displacement. In the pre-assembled position, the angular holding web 26 on the first web 21 engages the angular holding web 18 on the web 17.

[0024] Optionally, further profiles or projections can be provided on the webs 21 and 22, which engage with a corresponding contour on the outer profile 11 or inner profile 12. For example, a support web 36 is formed on the web 21, which, in the assembled position, rests against an inner wall of the hollow chamber 35. In the pre-assembled position, the webs 21 and 22 protrude essentially parallel from the first profile 10.

[0025] In Figure 5The assembly of the second profile 30 onto the connector 20 is shown. The second profile 30 is plugged with the outer profile 31 onto the web 21 and with the inner profile onto the web 22, so that the first web 21 is inserted into the hollow chamber 35 and the second web 22 into the hollow chamber 34. The webs 21 and 22 can be clamped in the respective hollow chambers 34 and 35. The second profile 30 has a flat cut-off end and is plugged onto the first profile 10 with the connector 20. Optionally, recesses or steps can also be introduced into the second profile 30 to enable deeper plugging. List of reference symbols
