Abstract

The window (10) is mounted inside the open rabbet (3) in metal sections (2) in the frame support (1). The rabbet has a flat bottom (4) onto which the window is applied. The bottom has a reception and immobilising groove (24) for a window support plate (15). The window is stuck on the support plate with an adhesive material (28) previously located on the plate. The plate is made from plastics and has legs (20,21) for anchoring in the groove which enable extraction of the plate out of the groove following an appropriate pulling force exerted perpendicular to the rabbet bottom.

Description

The present invention relates to a device for mounting glazing inside the frame of a frame door, window or facade element of a building, this frame being made up of profiles, generally metallic, forming the sides of this frame and joined to the corners thereof.

Glazing, consisting of a single glass panel or the case two parallel panels braced according to their periphery, delimiting between them a closed space where a insulating air space, is attached to the chassis when coming lodge in the opening of it, inside a open rebate provided in the profiles which form the frame, this glazing coming to be applied against the bottom of this rebate which extends parallel to the plane of the glass panel and which is laterally bordered by a return perpendicular to this bottom. Of shims are advantageously arranged between the return plane bordering the rebate and the peripheral side of the glazing to ensure proper centering of the latter relative to the frame.

To allow the glazing to be held in place, various solutions have already been envisaged in the art, consisting for example stapling or blocking the glazing with clips external engaging on the profile, or to immobilize this glazing by means of a piece called glazing bead, fixed on the frame in front of the glazing and coming to bear on the edge thereof to apply it against the bottom of the rebate.

Another solution implemented more recently, consists in use a link bar, immobilized before the installation of glazing in the bottom of the rebate, in particular in a longitudinal groove formed in this bottom, this metal bar being made of a material compatible with a putty deposited on the bar to ensure the bonding of the glass thereon, this solution being known in the technique under the term of VEC for "exterior glazing glue".

These known solutions, however, have certain disadvantages, resulting either from operations necessary for the installation and fixing of the blocking elements of the panel glazed, or, in the case of VEC, the time required to ensure sufficient polymerization of the adhesive sealant, this also requires additional work by cleaning and weaving after applying this putty against the bar.

In addition, always in the latter case, during a break in the glazing, requiring its replacement, it is essential to also change the metal bars ensuring the connection with the panel, which requires their complete disassembly and is a long and delicate operation.

The present invention relates to a device for mounting of a glass panel in a support frame, which avoids these disadvantages, in particular by allowing replacement simple and rapid deteriorated glazing, this device can be easily installed without requiring a time comparable to that required for the replacement of the strips, in particular in a "VEC" set.

To this end, the device considered, for mounting a glazing inside an open rebate formed in the especially metal profiles of a support frame, in which the rebate has a flat background on which is applied the glazing, this bottom comprising at least one groove of reception and immobilization for a support plate of this glazing, bonded thereto by means of a material adhesive deposited on this plate prior to setting place of the glazing, is characterized in that the plate is made of plastic and has hooking means in the groove, arranged to allow extracting the wafer from it, following an appropriate lifting effort substantially perpendicular to the bottom of the rebate.

Preferably, the plate is made of a material thermoplastic, polyvinyl chloride (PVC), polycarbonate or other. In addition and according to various variants, the adhesive material consists of a hot-melt adhesive, epoxy, polyurethane or others.

According to a particular characteristic, the brochure has a flat base, with two legs projecting under it base, suitable for penetrating by rotation into the groove, the opening thereof by which is inserted the plate being delimited by two lateral edges under which the ends of the legs, which advantageously have a curved profile towards outside.

According to another characteristic, the flat base comprises also two lateral tabs, outside the groove, one of which is in contact with a plane return, perpendicular at the bottom of the rebate receiving the glazing, and the other of which leans against the surface of it, these tabs forming respectively an acoustic barrier and a seal.

Other characteristics of a device for maintaining a glazing in a window support frame or the like, established in accordance with the invention, will further appear through the following description of an exemplary embodiment, given to indicative and non-limiting, with reference to the drawings attached in which Figures 1 to 4 are views schematic, in longitudinal section of part of the chassis intended to receive a glazing held in place therein via a collage plate, these figures successively illustrating the various steps implemented.

In these figures, the reference 1 designates as a whole a window or door frame, made up of profiles metallic 2, extending along each of the sides of this chassis, usually rectangular in shape, and arranged to join each other in the corners of the chassis, preferably by being cut obliquely according to a so-called miter cut.

In the drawings, only one of the four profiles 2 appears, which thus form the chassis.

These profiles are generally obtained by extrusion and have a particular profile that does not directly matter to the invention and therefore it is not necessary to describe in detail here, except to specify that each of them is designed to present a rebate open towards the inside of the chassis, this rebate comprising a bottom 4 and a flat edge 5 perpendicular to this background. Advantageously, the profile 2 can have an external extension 6, constituting what it is agreed to call a beat, this being provided with a nipple attachment 7 for a joint 8 suitable for bearing on the framing or masonry 9 of the facade or wall in which fits chassis 1 (see Figure 4).

This chassis is also intended to receive inside of the rebate 3 a glazing 10, which is preferably constituted by two glass panels 11 and 12, parallel between them and maintained with a spacing given by a spacer 13, which extends along the periphery of the panels, the whole delimiting between these a space 14 where reigns an insulating air space (Figure 3).

It should be noted that the production of glazing 10 at two parallel panels is not necessary for placing implementation of the invention, this glazing may be formed of a only one panel in particular.

According to the invention, the glazing 10 is provided for be placed inside the rebate 3 of the profiles 2 of the chassis 1, in particular by coming to dispose of it parallel to the bottom 4 of this rebate and therefore, perpendicular to edge 5, as also shown by Figures 3 and 4, this glazing being held in position by means a bonding plate 15, including Figures 1 and 2 more directly illustrate the structure and installation.

The plate 15, made of thermoplastic material, especially polyvinyl chloride or polycarbonate, but without these examples being limiting, include a base plane 16, provided at its ends with two legs, respectively 17 and 18, whose own ends opposite the base, 20 and 21, are directed outward relative to the base, these legs having come from manufacturing with the latter.

Advantageously, the plate 15 also comprises at right legs 17 and 18, thin tabs 22 and 23, which are located substantially, on each side, in the extension of on either side of the base 16.

Each profile 2 also has, in its flat bottom 4, parallel to the glazing 10, a groove 24, the opening of which is bounded above this bottom by two inside edges 25 and 26 respectively, facing each other of each side of the groove, these edges being provided so that, when the plate 15 is placed in this groove, as illustrated in Figures 1 and 2, the ends 20 and 21, due to the relative flexibility of the plastic material which constitutes this plate, come to engage under these edges thus immobilizing the latter against the bottom 4 of the rebate 3, the base 16 extending substantially parallel to this background.

The mounting of the glazing 10 in the profiles 2 of the frame 1, can easily be deduced from the attached drawings.

In Figure 1, prior to the installation of the glazing, each profile 2 is associated with a plate 15 place in the groove 24, preferably by engaging one ends 21 for example, of lug 18 of this plate under the corresponding rim 26, subjecting it to a slight rotation around the latter, until the other leg 17 come to bend slightly to the right of the opposite ledge 25, then engages its end 20 under the latter, the plate 15 being then immobilized in the rebate 3.

In Figure 2, reference 27 schematically illustrates a device for depositing on the surface of the base 16 opposite the groove 24, an appropriate amount of glue or of suitable adhesive material 28 over the entire length of the brochure. This glue can be of any kind suitable for make a quick connection between the plastic material of the plate 15 and the glass of the glazing; in particular, we can advantageously use a hot-melt adhesive, epoxy, polyurethane or others.

In the next phase, shown in Figure 3, the glazing 10 is brought into the rebate 3 of the frame 1, such so that one of its panels, for example panel 12 directed towards the bottom 4 of this rebate, come and press against the base 16 at the place where the glue was previously deposited, in thus joining, after polymerization, the profile and the glazing.

During the assembly thus obtained, it is observed that the tabs 22 and 23 which extend the base 16, extends beyond the groove 24 to outside of it and come respectively to wear, for the tongue 22 against the surface of the glass panel 12, and for the tongue 23 against the return 5 perpendicular to the bottom 4 of the profile 2.

The glazing 10 can therefore no longer pivot and is detach from the chassis, it can then be easily straightened to be placed upright, as shown in Figure 4, the tightness during assembly being advantageously performed by placing, between the peripheral edge of this glazing and the end of the return 5 of the profile 2, a seal seal 30 of suitable profile, of which Figure 4 illustrates a particular example.

This produces a device for mounting a glazing in a support frame, very simple and inexpensive in design, very easy to install in the chassis.

The plastic insert has the advantage essential, in case of glass breakage, to be able to be easily replaced with it, without the need to perform no particular intervention on the chassis itself, the insert which can be extracted from the groove in which it is maintained, by exerting a traction force sufficient, perpendicular to the direction of the bottom to make drop the legs of the support to the edges of the groove, the deteriorated plate, remaining stuck on the glazing, be immediately replaced by another new plate.

The invention also has the advantage of providing the mounting a double barrier, respectively sealing and acoustic, thanks to the tabs 22 and 23, which rest, for one against the glass panel applied to the plate, and for the other against the vertical return of the rebate.

Of course, it goes without saying that the invention is not limited to the example of embodiment more especially described above in reference to the accompanying drawings; on the contrary, she embraces all variants.
