Abstract

A window (8) frame or a door frame has a profile with a void (22) incorporating a heat insulation strip (10) that fits in the void. The interface between the heat insulation strip and the surrounding profile (2, 3) is closed by ridge profiles (13, 14).

Description

The The invention relates to a heat-insulating strip for a Glasfalz on a frame profile of a window, a door or a Facade according to the preamble of claim 1.

Such a heat-insulating strip is of the generic type EP 0 636 760 B1 known. This document shows a window with a disc and a frame whose individual frame profiles are formed as thermally insulated aluminum composite profiles, each consisting of an outer shell and an inner shell made of light metal, to reduce the thermal conductivity of the outer shell of light metal and the inner shell made of light metal Insulating strips made of plastic shear-resistant connected to each other, which engage in grooves of the outer shell and the inner shell and connect them firmly together.

Of the to the disc facing area between the outer shell, the inner shell and the Isolierprofil is also referred to as Glasfalz, the whole the disc rotates. In the Glasfalz grab the edges of the Surface elements - here the Glass pane - one which by at the outside and inner shell of the composite profile adjacent seals and / or glass slats are held in a sealed manner on the frame.

In the glazing rebate are in the area of the inner and in the area of the outer shell each separate thermal insulation strips used. By this measure is between the heat insulation strips a space formed for venting and draining the Glasfalzes is useful.

At This construction is problematic that can be through the use of two separate heat insulation strips the assembly costs increased.

Also the CH 678 747 A5 discloses generic thermal insulation strips, in addition to the insulating profiles are used in the Glasfalz. These heat insulation strips are in one piece trained so they nearly fill the entire glass fold, wherein these heat insulation strips with a bridge on one of the disc sides abut.

At this solution is disadvantageous that between the insulating glass pane edge and the heat insulation strip no space for necessary ventilation more given is. Another disadvantage is that the heat-insulating strip designed only for a thickness of insulating glass is, because with disks of other strength, which correspond with seals adapted sealing height are held on the frame, the thermal insulation strips are not usable. This requires the use of different thermal insulation strips, if different thick or thick insulating glass panes are used.

To is in the known versions of : Infill-insulating strips the assembly solved unsatisfactory.

It is therefore the object of the invention, the heat-insulating strip of the prior art to develop so that at furthermore good heat effect simplifies assembly and ensures a secure hold in the glazing rebate becomes.

The Invention solves this object by the subject of claim 1.

According to the invention the thermal insulation strip at least one or more holding webs, with the composite profile cooperate or behind undercuts on the composite profile so behind, that on at least one place a form and / or adhesion of the thermal insulation strip realized on the profile.

To In contrast, the prior art, the thermal insulation strips were many times only loosely inserted in the glass rebate, which increases the risk of slippage or of getting lost.

It is according to the invention possible, the thermal insulation strip still easy to assemble. On the other hand, it ensures that she can not be lost accidentally. In particular, it is possible at suitable embodiment of the or the holding webs and the corresponding Hollow profiles to realize a pre-assembly already in the workshop.

In order to becomes the assembly reliability increased at the construction site and reduces the installation effort during installation at the site. Unlike the insulating strips for connecting the outer shell with the inner shell must additional thermal insulation strip in the glazing rebate do not contribute statically to the framework, i.e., it enough, if the stop of the thermal insulation strip on the frame profile is ensured such that she does not fall out of the frame.

advantageous versions The invention are given in the dependent claims.

following The invention is based on embodiments with reference closer to the figures explained.

It shows:

1 a section through the frame of a window, wherein in the figure wing and frame and a disc edge are shown; and

2 a thermal insulation strip according to the invention.

1 shows a window 1 with a frame 2 and a sash 3 , in the surface element as an insulating glass pane 8th is used. Alternatively, in the case of fixed glazing, the pane could also be in the frame 2 be held. The frame 2 is firmly mounted on the building. The sash frame 3 is on the frame 2 movably arranged.

The frame, here the sash 3 , or each of the sash profiles consists of an inner shell 4 and an outer shell 5 that have at least one or more - here two - insulating strips 6 connected to each other.

The insulating strips 6 are made of plastic and form a thermal insulation zone between the inner shell 4 and outer shell 5 , which are preferably made of a light metal, but which may also be made of a different metal or other material, such as plastic or wood.

The insulating glass pane is in the casement 3 in seals 9 and 9 ' held.

In the edge area of the insulating glass pane 8th is to the sash profile 3 towards a glazing around the glass preferably circumferential 22 formed, which is virtually the entire space in the edge region of the engagement of the insulating glass in the sash 2 equivalent.

To reduce thermally induced heat losses is in the Glasfalz 22 in addition to the insulating strips 6 a thermal insulation strip 10 used.

This heat insulation strip 10 points at their end sections 11 and 12 Stege 13 and 14 on, the form-fitting undercuts on angle bars 26 and 27 of the sash 3 to intervene or correspond with it.

According to the invention, at least one of the webs 13 and 14 form on the heat-insulating strip.

Preferably, however, are two or more of the webs 13 . 14 provided to ensure a particularly secure hold of the thermal insulation strip 10 to ensure the frame. It is also advantageous if the webs 13 . 14 are formed at an angle to each other.

It is also conceivable, the heat-insulating strip 10 to use in a window frame profile, if in this example for a fixed glazing directly an insulating glass pane or a panel is used (not shown here).

The bridges 13 and 14 , which engage here purely positively in grooves of the sash profile, the corresponding angle webs 26 . 27 for the engagement of the bars 13 . 14 has, ensure a secure hold of the thermal insulation strip 10 In profile. As a result, the heat-insulating strip can already be mounted in the workshop, since there is no danger that it will be lost during transport (before the insulating glass pane is used).

The thermal insulation strip 10 lies here with a substantially flat base 15 mostly directly on the glass fold limiting flat insulating strip 6 flush up. In addition, in this area an adhesive bond, the durability or the position of securing the thermal insulation strip 10 continue to increase.

At her from the insulating strip 6 facing away, projecting into the glass rebate side has the heat-insulating strip 10 here substantially parallel to the disc extending webs 17 on, between which grooves or channels 16 are formed. The bridges 17 preferably extend close to the peripheral disc edge and are formed so that they do not cover the edge of the disc completely circumferential. They also do not contribute to the maintenance of the thermal insulation strip, as they do not rest on the sides of the disc.

The webs designed in this way 17 make it possible, in each case for a given frame construction heat insulation strips 6 use the same dimensions with different thicknesses of glass.

In addition, the thermals in Glasfalz by the webs 17 and the grooves or chambers 16 optimized.

This is due to the arrangement of the channels 16 and footbridges 17 ensures sufficient ventilation of the insulating glass pane edge in a simple manner, which makes it possible to comply in a simple manner, for example, the installation instructions of the glass industry, which require adequate ventilation of the glass rebate.

Further significant advantages of the invention provides thermal insulation strip 10 with regard to the solution of the discharge of moisture from the region of the glass rebate.

Preferably, the heat-insulating strip 10 in the direction of the longitudinal extent of the window profile 23 interrupted in sections (lengthwise) so that occurring in the glazing (condensation) water in a drainage canal 20 between the sash profile 3 and the thermal insulation strip 10 can be derived, the water from the drainage channel in turn at specific points of the frame (not visible here) is derived.

This drainage canal 20 is achieved by a clever shaping of the thermal insulation strip 10 realized.

For this purpose, the heat-insulating strip 10 next to the on the insulating strip 6 resting base leg 24 one at an acute angle, especially at an angle 21 from 20 ° to 70 ° to the base leg 24 extending angle leg 25 on. As a result, in the space between the angle leg 25 and the outer shell 5 a chamber 19 designed as a drainage channel 20 serves to ensure drainage and ventilation.

The drainage area 18 or the angle leg 25 are located above the lowest point of the glassfold drainage. The drainage area 18 is located above the bottom of the drainage channel 20 ,

2 shows the thermal insulation strip according to the invention 10 individually in a sectional view.

Clearly recognizable are the base leg 24 , the angular angle leg 25 as well as the two end sections 11 and 12 each on the base leg 24 and at the angle leg 25 , The bridges 13 . 14 serve for positive engagement behind corresponding profile grooves or the angle webs 26 . 27 ( 1 ) on the inner and outer shell 4 . 5 the frame profile of the sash 3 , This ensures a particularly secure grip, wherein the heat-insulating strip can already be mounted or fastened in the workshop before the installation of the insulating glass panes.

As a material for the production of the thermal insulation strip 10 Preferably, an elastic plastic is used, in particular of a foam with closed pores. The use of other elastic, heat-insulating materials is also conceivable.

The base 15 of the base leg 24 the thermal insulation strip 10 is well-formed and is well suited to apply adhesive tapes or adhesives, which cause additional retention of the thermal insulation strip.
