Description

The present invention relates to a method for producing a window profile, in particular wing profile or frame profile for wood-aluminum windows, for wood-plastic windows, as well as for wood windows and a window profile produced by the method.

In conventional methods for producing a window profile, in particular a wing profile or a frame profile, each leg of a window profile is cut from a wooden profile, then profiled in particular for the insertion of the glass of the seals and the corresponding window gear.

After joining the individual cut profiles, these are joined together and, for example, subsequently painted.

Each individual part, in particular each individual profile is profiled separately and then joined together with the other parts or profiles for complete sash profile or sash.

The disadvantage is that such operations are very complicated and expensive. This has proven to be disadvantageous, especially in wood-aluminum windows, since, for example, outside on the wooden frame an aluminum coating or panel is costly applied. Inside, especially on the visible surfaces of the wing or frame profiles, they must be painted accordingly or provided with a coating.

As a result, a very high production cost in the conventional production of wood-aluminum windows or wood-plastic windows is operated to produce them.

DE 16 84 125 A discloses a system for the formation of closure devices, in particular for windows, wherein a wood core is completely and integrally surrounded by a sheath. In the casing corresponding recesses for disc mounts and sealing profiles are provided.

DE 816 011 C discloses a method for splitting of components, in which twin pins are pressed into two adjacent adjacent bores of two components for connecting these.

From US 4,566,234 a window frame profile is described, which is provided with a coating. there The coatings are made inside and out of different materials.

The present invention has for its object a method and a window profile to create, which are facilitated in a very simple and cost-effective manner, in particular the manufacture and production of such window profiles, especially for wood-aluminum windows,
in particular, the production costs should be reduced. Furthermore, a high degree of production with very high precision and higher stability should be guaranteed.

To achieve this object, the features of claims 1 and 10 lead.

In the present invention, window profiles are preferably profiled as wing or frame profiles of one-piece wood elements or wood profiles in, for example. A length of about up to 6 meters. Ie. the individual grooves, gear grooves, Glasfalze, radii and the like are milled over the full length.

Subsequently, the elongated window profile, in particular wing or frame profile is provided with a coating or sheathing, in particular in the visible surfaces. It can be used as a coating or sheathing a wood veneer and glued to the window profile.

The coating or cladding over the entire length of, for example. 6-meter long window profile is glued. In this case, the coating or casing protrudes into the corresponding gear grooves or glass folds and completely encases the window profile in the visible surfaces.

As a coating or sheathing and plastic films, plastic laminates, metal layers, metal foils od. Like. Can be used. As a result, an individual design of an inner visible surface of the window profile can be customized.

Possibly. If the coating is also designed as a wood veneer, that entire profile is painted over the full length.

Subsequently, if necessary, this should be necessary, the visible surface with a protective layer, in particular protective film are provided to protect the visible surfaces from damage.

Then the elongated window profile, in particular wing profile or frame profile is cut to the desired length, sawed on Gährung to assemble the individual profiles to the window. In this case, the end side corresponding connecting elements in grooves, dowel pins, fitting holes od. Like. Used and the window profiles frontally connected to each other.

The grooves for the connecting elements are milled only close to the visible surfaces frontally, so that the connecting elements are not visible from the outside.

The end-side dovetail connection is so accurate and firm and is possibly additionally centered on dowel pins, so that after gluing an additional processing of the visible surface, in particular the coating can be omitted. The window is finished assembled from the individual profiles and is only equipped with the appropriate fittings and gaskets as well as with the glass.

In this way, in particular, a manufacturing process is created which creates an individual viewing surface, with a connection between two frontal window profiles, especially cut to length and beveled sash or frame profiles is created, which ensures a high and accurate fit stability, which are to assemble precisely. In addition, there is no subsequent painting of the window or window profile after assembly. This ensures significant time savings.

Further advantages, features and details of preferred embodiments of the invention will become apparent from the following description and the drawings, which shows in
Figure 1 shows a section schematically represented by a window profile, consisting of a plurality of wing and frame profiles with intermediate widening profile;
Figure 2 is a schematically illustrated cross section through a wing profile of a window profile;
3 shows a cross section through a frame profile of a window profile;
Figure 4 shows a longitudinal section schematically represented by a combination of two window profiles with connecting elements;
Figure 5 shows a schematic longitudinal section through a junction of two window profiles with at least one inserted connecting element.

According to FIG. 1, window profiles 1 consist essentially of a sash profile 2 and a correspondingly matching frame profile 3. can connect to frame profiles 3 via corresponding X-cheeks connecting elements 4, which engage in corresponding grooves 5, a connection to, for example, a widening element 6. Instead of the widening element 6, corresponding connections, such as blind boxes, frame elements or the like, can also form the corresponding connection or receptacles of the frame.

Essentially, an outside of the wing profile 2 and an outside of the frame profile 3 is provided with an aluminum casing 7.1, 7.2 in wood-aluminum windows.

In particular, these areas of the sash profile 2 and the frame profile 3 are covered externally by means of the aluminum shuttering 7.1, 7.2. Remaining visible surfaces 8.1, 8.2 are exposed. The visible surface 8.1 of the wing profile 2 in this case has a glass rebate 9 and at least one gear groove 10 for fittings.

It has proved to be particularly advantageous in the present invention, the window profile 1, in particular wing profile 2 and frame profile 3, which are made of wood, for example. Produce in 6-meter sections. The grooves 5, 9 glass rebate and gear groove 10 and the entsprechnden not shown radii and folds are milled into the one-piece material, in particular in the wood profile by means of, for example. Profiling over the full length.

After the corresponding profilings such as glazing rebate 9, gear groove 10 and grooves 5 and corresponding radii have been produced, the surface may be finely ground and then, as shown in particular in FIGS. 2 and 3, provided with a coating 11 or sheathing. In this case, the coating 11, in particular sheathing in the region of the visible surfaces 8.1, 8.2 is connected to the sash profile 2, in particular the frame profile 3. The coating 11 or sheathing is preferably wood veneer, but also plastic film, metal foil, plastic o. The like ..

The visible surfaces 8.1, 8.2 are preferably provided with the coating 11, in particular sheathing. In this case, the coating 11 protrudes into corresponding grooves 5 of the glazing rebate 9 or into the gear groove 10 and completely encases the sash profile 2 or the frame profile 3 in the region of the visible surfaces 8.1, 8.2.

In this case, over the full length of the elongated profile, which was pre-profiled accordingly, the coating 11 is applied. Preferably, the coating 11 is glued, in particular firmly glued to the sash profile 2 or frame profile 3. These are preferably made of wood.

If, for example, the coating 11 or sheathing is a veneer, then the elongated profile provided with the coating 11 is subsequently painted or surface-treated accordingly.

Only after the complete coating of the window profile 1 over the complete profile length, preferably 6 meters, the individual profile lengths for the corresponding window are sawed off from the window profile 1, in particular from the sash profiles 2 or frame profiles 3, or mitred.

Subsequently, the mitred individual window profiles 1 are frontally provided with corresponding connecting elements 12, preferably by means of a dovetail connections, wherein the dovetail-like connecting elements engage in correspondingly formed grooves.

Furthermore, dowel pins 13 can engage one another at the end in order to precisely produce a centering of the frontal connection of the window profiles.

Another advantage of the present invention is that by producing a very long profile, by the subsequent production of the corresponding profiling and the subsequent application of a coating, the desired lengths of wing or frame profiles 2, 3 for producing a window only by Cutting to length can be made. These need only be connected to each other at the front, a subsequent painting or subsequent coating of the window made of the sash profiles 2 and 3 profiles omitted.

Due to the fact that the corresponding grooves for the connecting elements 12 are milled in frontally only close to the visible surfaces 8.1, 8.2, the corresponding connecting elements 12 can not be seen from the outside.

In the frame profile 3, two dovetail-like connecting elements 12 are preferably used spaced next to one another and preferably three in the wing profile 2. However, the invention is not limited here. In this case, a plurality of corresponding connecting elements 12, as indicated in particular in Figure 5, frontally rotated by 90 ° relative to the embodiment according to Figure 4, the corresponding window profiles 1 together.
