Description

TECHNICAL FIELD The present invention relates to an improvement to

  glazing supported, without putty, by profiles, ensuring the str str hook of the immobilizing member of the glasses which rest on wings on either side of the soul of the profiles which, themselves, each present two longitudinal grooves with narrower entry than the bottom, namely on the top, so that anchors a bead of an elastic profile having two support wings on the outer glazing, - on the bottom, so that there anchor the fastening bolts to the frame, said profiles optionally having, in addition, the support grooves of elastic strips for holding an underlying glazing, the glazing covering, like any flat roof element, to the way of fish scales in

revealing pureaux.

  Problem posed This is to ensure the best seal

  possible to glaze the category that has just been described-

  whether it be double or simple. In fact, a large part of the insulation provided by the double glazing is lost, for example, if the airtightness is not ensured and the calories are evacuated by a simple ventilation which does not is not planned, scheduled or desirable. In greenhouses, in particular, it is, of course, necessary to provide ventilation but gold, prefers to be able to effectively control it through openings or artificial ventilation. or natural. Furthermore, it is interesting to give a clearer appearance below the profiles of existing glazing to avoid protrusions that may cause

accidental hooks.

  State of the art and disadvantages The current state of the art is clearly established by the French patents 1,097,877 of April 8, 1954 and 1,367,717 of June 15, 1964. These patents describe the glazings which have the great advantages of eliminating the putty but which have a complicated section and must hang on the frame by bolts that project and that sometimes present a danger and which, in any case, are unsightly. In addition, these profiles provide a thermal bridge on which condensation occurs preferentially. This is particularly important in the case of double glazing. Current improvements in the insulation technique have particularly highlighted the disadvantages of the thermal bridges that the present invention proposes to eliminate, which is important not only in greenhouses but also in constructions such as verandas. . In addition, the improvement of the insulation has highlighted a well-known phenomenon of previous glazing which is the natural ventilation caused by the space or the gaps which necessarily exist between the windows and the wings of the profiles since said windows overlap each other in the manner of tiles or scales of fish or, if one prefers, overlap. It has been known for a long time that tiles, slates or partially overlapping glazing show a pureau which also indicates the height of this apparent part. More specifically, such a flat covering element has on the top, from the top to the bottom, - a part covered by the upper element, - a purse which ends freely up to the part o the flat element considered rests on the upper part of

the lower flat element.

  The flat element considered, on the underside, can be broken down into two parts namely: - an upper edge which rests on the rafters or profiled wings and which extends, for the greater part, which is spread in contact with said chevron or said profile wing - and since the lower portion rests on the lower flat member. Each flat element thus rests on two supports at each end and, in theory, it rests nothing on a height which corresponds to that of the pureau. Obviously, the mechanical flexions correct a little this geometrical state of fact and each flat element rests on a certain surface at its upper part and on another surface at its lower part. Between the two, it flexes and it reduces the space left free between itself and the element on which it

is supposed to rest.

  However, there is still a void that has

  a mechanical disadvantage (mechanical work with flexion-

  exaggerated of said flat element) and a thermal inconvenience since a space and a natural ventilation is established

automatically in the cover.

  The present invention is intended to remedy these

disadvantages.

  U0U4. DESCRIPTION OF THE INVENTION The invention is characterized principally by the fact that the combination of a set of means improving the insulation, namely a) furring of the glazing against the wings filling the voids between these, that is to say, between the upper edge of a flat element and the top of the flat element which covers the first b) section covers section U stapling under the profiles and relying, in a sealed manner, below the furs provided for in a) and reserving, under the profiles, sufficient space to accommodate the fixing bolts' the frame, said furs and said cover-profiles being made of

insulating material.

  It is preferable to give the furs an inverted U-section shape, thus having, on the underside, a lower groove matching the edge of the profile wing and capping the latter while their upper part, flat, is -prévue for support and support, as tightly as possible,

to the glazing.

  According to a first embodiment, the furs are in several sections, each of which has a constant section but which is chosen less and less thick for each section as one rises under the glazing, along the profile-, said furs being made

made of elastic material.

  According to another embodiment, the furs are in sections with decreasing sections in the direction of the height to fit the wedge shape of the void

  between the glazing and wing of the profile.

  In general, it will be advantageous to make furs in a relatively rigid but elastic material, at least in the vertical direction. We can also double them either on the top or in the groove $ with a particularly elastic foam and

improving the seal.

  Another detail of the invention consists in providing that the upper edges of the profile covers have adjustment means at the lower edge of the furs. This adjustment can be made, for example, flat seal, groove and tongue. It is easily understood that with the device of the invention the spaces between the windows and the profiles are properly filled and that any undesirable ventilation is avoided. At the same time, it improves the contact between the glazing or flat element and the support profile. The phenomena of rupture by expansion or mechanical stress

  outside are greatly diminished.

  With the joint cover, which combines with the fur, it eliminates the effects of the thermal bridge of the profile and the insulation is further improved. In addition, the condensations that used to occur and flow along the profiles are recovered inside the cover and can be collected at the desired location for disposal. It is obvious that this joint cover will benefit from being made of a synthetic material, such as a plastic material obtained by extrusion and which has an excellent coefficient of thermal insulation. This profile cover also has the added benefit of removing any fastening bolts and avoid accidents they can cause. We obtain an aesthetic aspect

  considerably improved compared to the previous profile.

  The invention will be better understood by means of

  description below which gives some examples not

  practical limitations and which are illustrated in

the attached drawings.

  Description of some embodiments

  The type of glazing of the invention consists essentially of windows (1, 2, 3) resting, without mastic, on profiles such as (4) or (5). These are set at

  rafters (6) of the frame by bolts (7).

  The profiles (4) and (5) have a core (8, 9) and wings (15, 16, 17, 18) which are perpendicular to said core. Ailerons (19, 20, 21, 22) are supported at the ends of the wings (15, 16, 17, 18). It is on these that rest

the windows (1, 2, 3).

  3n In the case of double glazing (Figure 2), the lower part of its fins (21, 22) has a

  burying (23, 24) which supports the double glazing (25, 26).

  The struts (23, 24) produce grooves (12, 27) where

  the condensation water can flow, for example.

  Similarly, in the profile for single glazing shown in Figures 1 and 3, there is provided at the bottom of each fin (19, 20) a small gutter (28, 29) of

  recovery of condensation water.

  To immobilize the windows (1, 2, 3), there is provided a plastic profile (30) which covers the profiles (4) and (5) and presses the windows (1, 2, 3). This profile (30) has a bead (31) which fits into a groove (32) longitudinal inlet narrower than the bottom and which ends

  the upper part of the web (8, 9) of the profiles (3, 4).

  The lower part of the webs (8) and (9) - profiles has another longitudinal groove (33) with a narrower entrance than the bottom and which is intended to receive the head of bolts (7) intended to fix the assembly on the rafters (6). In the case of double glazing (FIG. 2), curved edges (34, 35) are provided at the top of each of the fins (21, 22) which serve to retain elastic rods (36, 37).

  which support obliquely against double glazing (25, 26).

  Everything that has just been described is part of the state of the art. We will now specify what makes

part of the invention.

  According to the invention, furring (38, 39) is provided for supporting the glazings (1, 2, 3) and (40, 41) for supporting double glazing (25, 26). The furs (38, 39) have a

  section which is clearly shown in Figures 8, 9, 10 and.

  1i and which has the shape of a U returned with a groove (42) which fits on the upper part of the fins (19) and (20) to interpose between the glazing (1, 2, 3) and the resilient plastic profile (30). In the case shown in Figure 2, that is to say that of a double glazing (25, 26), the furs (40) and (41) have grooves similar to the grooves (42) but which are here oblique, as clearly seen in Figure 2, and which are provided to fit furs (40) and (41) on the upper part of the straps (23, 24). Windows (25, 26) are supported on furs (40, 41). The furs (38, 39, 40, 41, 381, 302 and 383) are made of insulating material, for example extruded plastic such as polyethylene or the like. They can be obtained by molding or profiling or any other process. In any case, they will be made of a thermally insulating material and it will be advantageous for them to be at least slightly elastic. In the case, represented on the left of FIG. 5 and in FIG. 6, the sections producing the furs have a constant section; but two different sections are chosen for the furs (381, 382), the section of the fur (382) being smaller than the section of FIG. 381 to be able to adapt to the vacuum (43) (FIG. corner, existing between the glazing (1, 2, 3) and the profile (4). To achieve a better adaptation to this vacuum, it is expected (Figure 12) to fill the bottom of the groove (42) with an elastic fur (44). It is obvious that one can realize the whole of the

fur made of elastic material. -

  Another way of producing this fur is shown in FIG. 7 where a section with a decreasing section in the height direction is used to fit precisely the shape of the empty wedge (43). This form is more difficult to achieve since we must exclude spinning; the molding can be used. In this case, too, it will be advantageous to use an elastic profile. The other part of the device of the invention is constituted by the work-profiled section U (45) which closes. The upper edges rest, tightly below the furs (38, 39, 40, 41, 381, 382, 383). These upper edges generally have a simple curved flange (46) (Figures 1, 2, 3). However, the adjustment and sealing can be improved by providing, in addition, a tongue (47) which fits into an additional groove

  corresponding fur (38) (Figure 12).

  For stapling the profile cover (45), moldings (48, 49) are provided which are arranged longitudinally inside the lateral branches of the U-section of the profile cover (45) and which hang on either the gutters (28, 29) or the end of the lower fork (23, 24). The elasticity of the material of the profile covers (45, 451) enables efficient stapling.
