DE102012023538A1 - Plastic coupling strips for use in angle variable couplings for bent windows, have blind frame made of plastic, where variability of angle is reached by taper that is formed in middle parts of two different lath profiles - Google Patents

Abstract

The strips have a blind frame made of plastic, where variability of angle is reached by a cross-sectioned taper that is formed in middle parts of two different lath profiles, where the lath profiles are plugged together with a hinge. Variable coupling systems are arranged around a pipe of rotatable arranged junction channels. Coupling parts are arranged around a round blind frame profile, where diameter of the round blind frame profile is about 74 mm. Diameter of the junction channels is about 100 mm. Two coupling lath bodies are inserted in a joint.

Description

For the connection / coupling of window or door frame, which are not in alignment, but form angles to each other, special coupling profiles are used.

On the one hand, these may be profiles which have a rigid angle of 45 ° or 90 ° or, on the other hand, those which are variable in angle. The latter are constructed so that a part of this coupling can be arranged at any angle around a round profile.

The disadvantage of the latter solution is that at such coupling sites an extremely wide frame view of up to 233 mm - consisting of 2 frame with 69 mm and the coupling profile with a width of about 95 mm - arises.

Especially in the redevelopment of old wooden window systems, this is undesirable because you usually narrow frame-view widths of z. T. below 100 mm.

The specified in claim 1 invention is based on minimizing this view width for a certain angle range as far as possible.

This minimization is achieved by the features listed in the claims 2 and 3 for the coupling strips.

The embodiment according to claim 2 is in the drawing sheet 1, 1 and 2 shown.

The angle-variable double coupling strip is clipped into the adjacent frame profiles and can then be varied in angle.

The variability is between 5 ° and 44 °.

The width of the coupling profile is only 12 mm at a 5 ° angle.

The embodiment according to claim 3 is in the drawing sheet 2, 3 and 4 shown.

Here, the two coupling strips are put together in the joint, then clipped into the adjacent frame profiles and then varied in angle.

The variability here is between 2 ° and 44 °.

The width of the coupling profile is at a 2 ° angle here, too, only 12 mm.

To represent a much larger angle than 44 ° with these profiles makes no sense insofar as then the view width of the coupling of the previously used profiles does not differ significantly.

The stabilization / fixation of the connection is made with the usual coupling screws. The insulation and sealing is also done in the technical way appropriate way.

In the drawings sheet 5, 5 and 6 as well as sheet 6, 7 and 8th The connections between the angle-variable coupling strips and the frame (standard frame made of KBE profiles) are shown.

These coupling strips can also be used for all other plastic profiles for windows and doors. Optionally, the "lugs" that prevent lateral displacement of the frame against each other and to ensure a stable and secure connection thereof, slightly to modify the illustrated in the drawings.
