LU83438A1 - PROFILE IN PLASTIC MATERIAL FOR FIXING DOUBLE GLAZING IN RENOVATION - Google Patents

Description

". * - 1 -

Plastic profile, intended for fixing a1 double glazing under renovation 5 The invention relates to the installation of insulating panels with double glazing on window frames not having rebates of sufficient width to receive such panels. It is therefore, in practice, single glazed windows that one wishes to renovate.

10

We know that double-glazed panels are composed of two panes separated by an air gap and joined along their edges by an intermediate metal profile (generally aluminum) covered on its outer edge-15 with a gasket. insulating elastomer.

These insulating panels are installed after having demasticized and completely removed the old glass, by putting the panel in place by means of a profile which is fixed to the window frame by means of screws.

Various shapes of profiles have been imagined comprising a gutter wider than the rebate of the chassis and intended to receive the insulating panel and a fixing strip by 25 screws on the upright of the chassis. The most common profile has a Y shape * the gutter, formed by the fork eupé ~, lower of the Y, rests on one side of the upright and has /

~ T

- 2 - that the fixing strip, constituted by the leg of the y, placed at the bottom of the rebate is covered with sealant to ensure sealing, which affects the aesthetics as soon as the sealant has taken the dust.

5 The invention relates to a plastic profile of the general type mentioned above, of particularly simple installation and adapting to different forms of molding of the upright, while having a satisfactory aesthetic appearance and offering good weather protection.

The profile according to the invention comprises a U-shaped gutter made of relatively rigid plastic, a first lateral branch and the bottom of which bear on the bottom of the rebate of the upright, while the second lateral branch projects from the outer face of the upright and is characterized by a relatively rigid plastic blade, perpendicular to the bottom of the gutter and starting from the face of said bottom opposite the branches, said blade being placed to bear on the outer face of the upright and by a strip of plastic material articulated on the first lateral branch and relatively flexible, so as to come to marry the molding of the upright situated on the inside of the window, said strip serving for fixing the profile by means of screws cooperating with a cover -screw.

The various features, as well as the advantages of the invention, will become clear in the light of the description below.

The single figure of the appended drawing represents, seen in section through a plane perpendicular to a frame upright, a profile conforming to the preferred embodiment of the invention.

It can be seen that this profile has a relatively rigid plastic D-shaped gutter, the side / side 11 and the bottom 12 of which bear at the bottom of / 35 * * 3 "* rebate. This gutter is intended to receive a panel with double glazing P, t * other lateral branch 13 of the gutter is offset with respect to the external face E of the upright M of the frame, the width of the bottom 12 being greater than that of the rebate. Perpendicular to the bottom 12 and integral with the face of the latter, opposite the branches 11 - 13, a plastic blade 2, of the same rigidity as that of the gutter, comes to rest on the face E.

A strip of relatively flexible plastic 3 is articulated at 31 (for example by means of a narrow strip of even more flexible plastic hinged) to the lateral branch 11, the region 31 being located at the location 15 where the branch 11 protrudes from the rebate base s the strip 3 can thus match the face I of the upright, more or less inclined according to the frames and possibly including a molding. It receives screws for fixing to said face and a screw cover 4, itself made of plastic, 20 is articulated in the region 31 or in the vicinity thereof and comes to hang on the outer edge of the strip 3 .

Between the rebate bottom and the supporting parts of the gutter, there will usually be a gasket 25. Note that the path that water (or dust) should follow to penetrate towards the inside of the chassis between it and the profile having a first angle at the connection of parts 2 and 12, a second angle at the connection of parts 12 and 11 and a third angle to the connection of parts 11 and 3, excellent protection is ensured *

The profile being at the bottom of the gutter, it does not substantially mask the light. Its installation is particularly simple 35 and its aesthetic appearance satisfactory.

It goes without saying that modifications of detail may be / made to the profile described and shown, without departing from the spirit of the invention, (/
