FR2691500A1 - Window section - has cut back in upper part of rebate bottom forming space between double glazing and rebate - Google Patents

Abstract

The bottom of the rebate has its upper part (21) cut back parallel to its lower part (22) with its lower edge (23) chamfered. The double glazing (3) is formed from two sheets of glass (30,31) resting on the horizontal face of the rebate, and between which is inserted, a short distance from their periphery, a support (32). There is a groove (25) in the rebate. The cut back (21) allows an injection nozzle to be placed near to the right of the gap formed between the upper part (22) of the rebate bottom, the groove (25) and the double glazing (3), to be filled to form a sealing joint (4). A mastic type joint (5) is inserted between the glass (30) and the internal face (12) of the filler (11). ADVANTAGE - Enables a liquid sealing joint nozzle to be placed in the gap between the rebate and window.

Description

 The present invention relates to a window profile, or other leaf, French window or bay window, allowing in particular the optimal implementation of the method of fixing double glazing described by the applicant in its French patent 2,650,855.

 This patent describes a process allowing the external sealing of the double glazing to be produced in situ, at the same time as its assembly to the carpentry frame, by pouring or injection of a liquid mixture giving rise to a polymerization reaction at room temperature. .

In accordance with this process, the two glass sheets joined by a spacer placed at a short distance from their periphery, are arranged in the rebate of the frame laid flat before the injection or the pouring of the liquid mixture which fills all or part of the space available between the rebate base and the spacer, the glazing bead then being laid or fixed either by conventional means, screws or nails, or by gluing.

 This process, which makes it possible to produce double-glazed panels which are technically superior to existing panels, in particular in terms of sealing, and allows the automation of the production line, is however difficult to implement with the profiles of conventional type. .

 Indeed, because of the height and verticality of the rebate bottom and the narrowness of the void to be filled by the seal, it is not possible to approach the injection device close enough to be able to introduce the head d injection into the available space, which affects the good diffusion of the mixture in the chassis.

 The present invention aims to remedy this drawback by proposing a profile allowing easier and more efficient implementation of said method.

 Like the profile described in the aforementioned patent, the rebate of the window profile object of the present invention may have a groove in its horizontal face, on which rests the outer glass sheet.

 In accordance with the invention, in order to allow the approach of an injection device in line with the space to be filled and the introduction of the injection nozzle into said space, a recess is provided in the upper part of the rabbet bottom, this recess being parallel to said rabbet bottom, to which it is connected by an inclined plane allowing the guidance of the injection nozzle during its introduction into the space to be filled.

 After injection, drying and hardening of the seal, the glazing bead is conventionally secured to the recess and to the inner sheet of the double glazing, which does not modify the external appearance of the glazed panel.

 The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

In the attached drawing
- Figure 1 shows a cross-sectional view of a profile according to the invention, before the installation of the seal.

 - Figure 2 shows a cross-sectional view of the same profile after installation of the seal.

 If we refer to Figure 1 we can see that a profile 1 according to the invention has a rebate bottom 2 in the upper part of which is a recess 20 parallel to the lower part 22 of the rebate bottom 2, and whose the lower edge 23 is chamfered.

 The double glazing 3 consisting of two sheets of glass 30 and 31 between which is interposed, a short distance from their periphery, a spacer 32, rests on the horizontal face 24 of the rebate, in which a groove 25 is formed.

 The recess 20 makes it possible to approach as closely as possible an injection nozzle in line with the space 10 to be filled, and even to introduce it into this space 10, which is delimited by the lower part 22 of the rebate base 2, the groove 25 and the double glazing 3, the chamfered edge 23 authorizing a non-tubular flow of the product.

 If we now refer to Figure 2 we can see that after making a seal 4, by injecting a liquid mixture into the space 10, a glazing bead 11 is assembled to the profile 1, at the bottom 21 of the step 20, and covers the seal 4 and the periphery of the double glazing 3, a seal 5 of the mastic type having been previously inserted between the glass sheet 30 and the internal face 12 of the glazing bead 11.

 It goes without saying that the present invention cannot be limited to the preceding description of one of its embodiments, capable of undergoing a certain number of modifications without departing from the scope of the invention.

Claims (1)

 CLAIM  Window profile, or other leaf, for the optimal implementation of a process allowing the installation of the external seal at the same time as its assembly to the carpentry frame, characterized in that the rebate bottom (2 } has in its upper part a recess (20) parallel to its lower part (22), to which it is connected by an inclined plane (23), making it possible to approach as closely as possible to the right of the space (10) to be delimited delimited by said lower part (22) and the double glazing (3), a nozzle for injecting the liquid mixture intended to constitute said seal.
