Composite profile for windows, doors or the like.

The invention relates to a composite profile for windows, doors or the like. In which two partial profiles made of metal, in particular Light metal, are connected to one another at a distance by at least one connection profile made of plastic, the Connection profile on both sides with one engaging in a groove of the partial profile and one behind internal projections of the groove Has anchoring part which is elastically deformable for snapping into place behind the inner projections.

- 4th

In such composite profiles, what is known as an interrupted cold bridge is required, which is the outer partial profile of insulated from the inner partial profile in order to reduce the heat losses as j: to be kept as low as possible. Since the insulating materials generally have a lower strength than the Profile parts, the problem exists, on the one hand good insulation and on the other hand sufficient strength of the frame.

It is known to meet these requirements, the profile parts to be provided with elaborate profiles in order to adhere to the highest possible strength with satisfactory insulating properties to achieve.

It is also known (DT-OS 25 59 336) to provide a connection profile made of plastic to connect the partial profiles, which, on both sides, has one that engages in a groove of the cable profiles and that engages behind internal projections of the groove Has anchoring part which is elastically deformable for snapping into place behind the inner projections in the transverse direction of the groove is, wherein each anchoring part of the connecting profile is designed as a hollow profile.

With the first construction, considerable difficulties arise during assembly due to the complex profiles.

In the embodiment according to the DT-OS 25 59 336 is

a simple assembly is guaranteed, but the production is i

of the connection profile of the type described with relative \

associated with great difficulties, since I

is composed of four hollow profiles. In addition, 5

ί is the well-known composite profile of low strength, | because there is a possibility that due to the tolerances of §

individual parts whose engagement elements do not engage properly. Also, the profile can be simpler when it occurs Tensile forces are pulled apart.

The object of the invention is to provide a composite profile of the initially to create mentioned type, in which a simple mounting option is given and the connection profile itself is a simple profile.

This object is achieved according to one embodiment of the invention in that the connecting part is designed as a Η profile is that at the end parts of the legs of the H-profile as anchoring part lugs for engagement with the projections the partial profiles are arranged and the web of the Η-profile over the legs on both sides of the Η-profile is designed as a V- or U-profile that extends between the profile parts.

In a further embodiment of the invention it is provided that the connecting part as a substantially rectangular Hollow profile is formed, the lugs at its corners for engagement with the projections of the partial profiles are arranged and formed on two opposing webs V- or U-shaped projections, which extend resiliently between the metal profile parts.

The advantages achieved by the invention are in particular that the connecting profile on its V-shaped profile during assembly by the two partial profiles is resiliently compressed so far that the lugs of the connecting profile can safely snap into place behind the projections of the partial profiles. After the relaxation, the V-profile brings the protrusions of the Partial profiles firmly engaged with the noses.

7737202 I6.ea78

Without this V-shaped training and the associated The dimension "X" (Fig. 1) would have to be designed so that the manufacturing tolerances of the connecting element and the metal profile can be caught. This inevitably leads to it after the parts have been joined there is no firm contact between the noses and the projections. The result is a shift in the partial profiles to each other, which leads to a non-parallelism and instability of the connection profile.

The connecting profile itself has a simple profile cross-section so that it can be manufactured cheaply. The training according to the second embodiment of the invention also gives good thermal insulation properties through the cavity of the connecting profile.

Embodiments of the invention are shown in the drawing and are described in more detail below.

It shows:

Fig. 1 is a sectional view of an embodiment of the invention with an H-profile;

Fig. 2 is a sectional view of a further embodiment of the invention with a substantially rectangular Hollow profile.

In Fig. 1, two partial profiles 38, 40 made of metal, in particular made of light metal, shown, between which a? binding profile 10 with a substantially H-shaped profile cross-section is arranged. The H-shaped profile has legs 12, 14, at the ends of which lugs 16, 18, 20,

7737202 I6.oa78

22 are formed. In the anchored state, the noses come into engagement with projections 24, 26, 28, 30 of the partial profiles. The legs 12, 14 of the Η-profile are connected to one another by means of a web 32 , which gives the anchoring part the necessary strength. The web 32 extends over the legs of the Η-profile and assumes a V-profile-shaped shape 34, 36 on the outer sides of the legs 12, 14.

The connecting profile 210 shown in Fig. 2 consists essentially of a rectangular hollow profile with slightly arched wall surfaces. Lugs 216, 218, 220, 222 are formed with projections in each case at the corners of the profile the partial profiles 38, 40 come into engagement. On the shorter wall surfaces 212, 214 are each arranged in a V- or U-shape Projections 234, 236 are provided, which engage resiliently between the partial profiles 38, 40.

With the composite profile according to the invention, good dimensional accuracy is achieved of the composite profile reached. The connection profile can be easily installed by pushing it in and grants a secure connection of the same by locking the lugs with the projections on the partial profiles.

By lengthening or shortening the individual dimensions of noses, legs, webs and protrusions accordingly can the shapes of the composite profiles according to the invention in can be varied widely.
