Description

Device for fixing a flat surface, in particular made of glass, to a support frame.

The invention relates in particular to the fixing of a glazing or the like on an opening or fixed frame prepared in the workshop, independently of the means of framing of said glazing.

It is known, in the prior art, the so-called "glued" glazing which consists of gluing said glazing against a metallic support frame generally made of aluminum, surrounding the latter, in which it is centered by interposition of seat wedges arranged between the edge of the glazing and the return of the support frame. To ensure the seal between the inner face of the glazing and the frame, at least one seal is used which is glued on the one hand to a face opposite said frame and on the other hand to the corresponding face of the glazing.

This seal provides the double sealing and securing function of the glazing against said frame, the external part of said glazing being free from any fixing except for a security profile.

It is also known a French patent No. 2,617,229 claiming a bonding profile made of aluminum or other material compatible with the seal or the sealant, of a section comprising either two grooves or a dovetail; intended to be slid into a corresponding hollow housing of the support frame, said profile being lower than the seal, the latter projecting on each side of the profile on the support frame.

A double glazing frame is known, in which the inner glass is embedded in a seal. As with the types of glazing previously mentioned, the assembly must be carried out in the workshop, and in the event of subsequent breakage on the site or breakage during installation, complete removal of the entire frame is necessary to remove the broken glazing and replace it with a new one. The assembly of these glazings is long, delicate and expensive, plus the delay in bonding and drying the joints. For all these methods of fixing and installing glazing on site, it is often reported externally a safety profile to hold the external glass, which affects the aesthetics of the facades.

The mechanical strength of these glazing fixing means is ensured by bonding to fluent joints.

The object of the present invention is to propose means capable of remedying these drawbacks and considerably simplifying the installation of the glazing, both in the workshop and on site.

The invention is described in the following text, with reference to the single accompanying drawing plate given by way of nonlimiting example of the invention.

 As presented on the drawing board, the device for fixing glazing frames, shows in the upper part an example of mounting double glazing and in the lower part, an example of mounting simple glazing.

 The double glazing 1 is fixed to a frame 2 arranged so as to allow the glazing 1 to be put in place from outside the frame 2 in the direction of the arrow 3. The frame 2 is articulated on a structural section 4 on which it seals with a seal 5, 6. The frame 2 comprises a tubular body, preferably made of light alloy like all the other profiles, having an outer wing 7 whose outer face 8 is arranged parallel opposite with the inner glass 9 pushed against said face 8 by means of a seal 10 with multiple lips embedded in an open frame profile 11.

This profile is U-shaped with asymmetrical wings; a large wing 12, face side 8 of the chassis, and a small wing 13 parallel to the wing 12, comprising a slot 14 receiving the screws 15 for fixing said profile 11 on the fixed or opening chassis 2.

The wing 13 also includes a honeycomb 16 in the bottom of the slot 14 for the assembly of the profile 11 in the frame of the double glazing 1. The seal 10 with multiple lips is embedded in the profile 11, it has a complementary lip 17 which rests on the one hand on a square return 18 comprising a small wing extending parallel downward to serve as the bearing face of the lip 18 of the seal 10 which is simultaneously supported on the vertical face 8 of the chassis opposite, to avoid water rising. The profile 11 is supported, by its lower wing 19, on a shim 20 placed on an extension 21 of the frame 2 perpendicular to the face 8.The passage of the screws 15 is pre-drilled in an extra thickness 22 of the extension 21; the profile 11 is clamped against the wedge 20 placed on said extension by means of a set of self-tapping screws 15, engaged in the slot 14 into which they are screwed.

The seal between the wing 13 of the profile 11 and the outer glass 23 is ensured by means of a seal 24 injected at the pump. The end of the extension 21 of the chassis 2 comprises a slide 25 intended to receive a seal 26 ensuring the seal between the simple external window 27 arranged in the low position. This seal bears on the one hand against the internal face of the window 27 and at right angles against the edge of said window. The external window 23 of the double glazing is also supported on small flanges 29 after interposition of an elastomer plate or the like 30, glued to said flange. These flanges 29 are fixed by means of screws 15 with a flat head, or with the same countersunk head screws, but after interposition of a milled washer 31.

This flange has the function, in the lower part, of retaining the single pane or the outer pane of double glazing, in the event of any loosening or sliding.

 The front part of the fixed lower chassis 40 is identical to that of the chassis 2, but is mounted symmetrically with respect to the axis AA. The fixing of the section 41 of the single glazing frame is identical to that of the section 11 for double glazing. This section 41 is in the form of a square. It has a vertical face 42 extending at 43 by a very thick wing identical to the wing 13 of the profile 11. This wing has the same slot 14 opening into a socket 16, this wing can be extended by a thin wing 44 parallel to wing 45 of the square. The wing 45 ends with a small portion of wing at 900 46 which abuts against the face 8 of the fixed frame 40. The glass 27 is assembled on the framing profile 41 by means of a glued joint 47 bonded. both on the internal face of the window 27 and on the face 42 of the framing profile. A spacer seal 48 is arranged above the seal 47. The seal between the glass 27 and the profile 21 is ensured by a seal 26. The profile 41 is locked on the extension 21 of the frame 40 by means of the screw 15 after interposition of a wedge 20. A safety piece 51 is arranged at the angles of the double glazing and of the single glazing, which is mounted by means of a bonding joint 47.

 This part is formed by a small portion of a square profile, the vertical outer wing 52 of which is short and has a little play with the window 27.

It is fixed to the extension 21 by means of one of the screws 15 after interposing a shim 53 of thickness. A panel 54 is placed between the seals 55, 56.

The fixed frame 40 is fixed to the structural section 4 by means of small sections 57 and self-tapping screws 58 screwed into a slot 59 of said section 4.
