Description

The invention relates to an insulating web for a composite profile for window, door or facade elements and a composite profile for window, door or facade elements with insulating web.

Thermally insulated composite profiles for window, door or facade elements are known in the art. Typical composite profiles of this type have two metal profiles, which are connected by one or more plastic insulating bars and thermally separated. Preferably, the metal profiles are made of aluminum or other light metals.

Examples of such composite profiles can be found in the EP 1 997 998 A2 who is the E 42 38 750 A1 , of the DE 195 28 498 C1 , of the EP 2 044 284 B1 and the US 5,469,683 A , Further composite profiles and insulating bars are known from the brochure "Standard Profiles 2012" of TECHNOFORM BAUTEC. From the EP 1 255 019 A2 , of the DE 2007 016 649 U1 and the DE 298 05 607 U1 insulating bars are known with hinges.

The DE 20 2012 006 555 U1 discloses an insulating web for a composite profile with an integrally molded lid. The lid can be opened via a hinge for inserting a foam body and then closed by a clip connection for holding / clamping the foam body.

Fig. 1 shows by way of example a section of such a composite profile in a cross-sectional view XY perpendicular to a longitudinal direction Z. In the composite profile, two aluminum profiles 31, 32 are interconnected by two insulating bars 10 and thermally separated from each other. The insulating bars 10 and the aluminum profile parts 31, 32 are connected to each other by rolling. The known from the prior art process of curling is in Fig. 2 shown in a cross-sectional view XY perpendicular to the longitudinal direction Z of the composite profile or the insulating web.

The insulating webs each have an Isolierstegkörper 20 which has at its transverse in the transverse direction (width direction) X perpendicular to the longitudinal direction Z outer sides formed as Einrollköpfe 25 longitudinal edges. The curling heads 25 have a substantially trapezoidal Cross-sectional shape which is substantially complementary to the shape of a groove formed in the aluminum profile parts 31, 32. The groove is bounded by a web 34, which is also referred to as an anvil, and a web 33, also referred to as a rolling hammer. The web 33 is deformed by plastic deformation by means of rollers, not shown, from the position shown in solid lines in the dashed lines (= rolling in) , As a result, a shear-resistant connection in the longitudinal direction Z is produced, optionally supported by a knurling of contact surfaces. At the same time, the aluminum profile parts 31, 32 in the transverse direction X and Y (width and height direction) are positioned relative to each other and thermally separated.

As in Fig. 1 is good to see is in the connection of the two aluminum profiles 31, 32 through the two insulating bars 10 in the Fig. 1 shown limited a hollow chamber 33 which has a completely closed outer wall in cross section XY perpendicular to the longitudinal direction Z.

From the above documents is known by way of example that there are various approaches to subdivision of the hollow chamber 33 by transverse webs / walls / ribs o.ä. in particular to hinder the heat losses from one aluminum profile part 31 to the other aluminum profile part 32 or vice versa by convection and / or radiation.

Fig. 3 shows by way of example a section of a composite profile in a cross-sectional view XY perpendicular to a longitudinal direction Z, wherein in this composite profile, the two aluminum profiles 31, 32 are interconnected by two insulating webs 10, each having a transverse web 21. The respective transverse web 21 extends from a side of the Isolierstegkörpers 20 facing the cavity 33 along the height direction Y. The overlapping of respective end regions of the transverse webs divides the hollow chamber 33 into two hollow chambers.

The distance between the two insulating webs 10 in the vertical direction Y can take different dimensions depending on the type and size of the composite profile, so that insulating bars are to provide with different lengths transverse webs. The transverse webs can reach lengths that require larger tools (eg injection molding) for the production of Isolierstege. This in turn requires an increased need for material for the tool and a larger footprint. Furthermore, arises due to the dimensions of such insulating bars also an increased demand for packaging material and storage capacities. Furthermore, deformations and damage may occur during packaging, storage and transport of the insulating bars, in particular on the transverse bars.

The object of the invention is to provide a composite profile for window, door or facade elements with an insulating web for such a composite profile, which allows a simple and kostenreduziernde manufacturability and storage and transportability.

This object is achieved by an insulating web according to claim 1, 2, 7 or 8 or a composite profile according to claim 14 or 15.

Further developments of the inventions are specified in the dependent claims.

The hinge clip device for an insulating bar allows the functional element (crosspiece) to be pivoted to a state in which the crosspiece only at a desired time after production (eg following the production or directly before the assembly of the composite profile) projects with predetermined maximum length of the insulating web and is held reliably by means of the clip connection in this position. This ensures a simple, compact and therefore cost-effective design of the production tool and at the same time a reduced need for packaging material and storage capacity. Furthermore, deformations and damage, in particular at the transverse webs are reduced, since they have a pivoted state during storage and transport (can).

The transverse webs / walls / ribs / connecting webs can also be provided for holding foam bodies, wherein the foam body impede the heat conduction between the aluminum profiles in addition to the transverse webs / walls.

Furthermore, the protected side of the transverse web, ie the side which faces the insulating web in the pivoted state, have a coating, for example a metal coating, which is protected due to the pivoted state of the transverse web during transport and storage.
