Description

DESCRIPTION

The present invention relates to a window element for a building, a sliding window installation comprising at least one window element according to the invention, as well as a method for manufacturing a glazing element according to the invention.

The field of the invention is that of window elements for buildings, and more particularly that of window elements for sliding window installations of large dimensions, provided for separating the interior from the exterior of the building having performances of high thermal insulation.

The term “large window element” is understood to mean a window element having a glazed surface area greater than approximately 6 m ² , and a weight generally exceeding approximately 400 kg.

Generally, large window elements have cross members of a length greater than lm50, in particular greater than 2m and uprights of a length greater than lm50, in particular greater than 2m.

As is well known to those skilled in the art, and as shown in FIG. 1, a window element 1 for buildings essentially consists of a frame 2, comprising vertical uprights M and horizontal crosspieces T, and a glazing 3, fixed between the uprights and the cross members of the frame 2.

The chassis 2 is generally rectangular in shape, and usually has two vertical uprights M and two horizontal crosspieces T, parallel to each other. The uprights M and the cross members of the chassis T are made up of carpentry profiles of wood, metal, synthetic material (plastic for example), or a mixture of these materials. The uprights M are fixed perpendicular to the sleepers T by various means, in particular by welding or screwing.

The glazing can be single, double or triple glazing. It thus comprises one or more parallel panes, possibly separated by a strip of insulating gas, in particular air, and optionally covered, on their internal face with a thin layer of insulating treatment.

In the case of a large window element, double or triple glazing will necessarily be used, so as not to degrade the insulation of the building and meet the requirements of the standards in force.

The panes are generally made of monolithic glass, but can also be composed, in part or entirely, in particular in the case of laminated glasses, of other transparent materials, such as certain thermoplastic materials, such as Plexiglas for example.

As can be seen in FIG. 2, the glazing 3 is fixed in the frame 2, in its rebates F, so that the glazing (s) of the glazing are arranged substantially parallel to the median plane Pm of the chassis 2.

Well known to those skilled in the art, and according to the construction standards currently in force, and for example in France according to the French standard NF DTU 39 in its amended version of July 2012, glazing, when made up of a multi - glazing (ie double glazing or triple glazing) must be fixed to the frame by means of shims, distributed on the inner periphery of the frame, in the bottom of the rebates of the joinery profiles.

These shims are dimensioned and positioned on the inner periphery of the frame so as to transmit the weight of the glazing to precise points on the frame, and to ensure the positioning of the glazing according to the desired orientation in the frame, as well as keeping it stationary when setting the door in motion or other external stresses.

As can be seen in FIG. 3, which represents the assembly of a frame 2 and a glazing 3 of a window element 1 according to the state of the art, several types of shims C1, C2, C3 , C4 are provided between the frame 2 and the glazing 3, arranged on the inner periphery of the frame 2.

These wedges Cl, C2, C3, C4 can be made of treated hardwood or plastic

Cl seat blocks are provided on the lower upright of the frame 2 and are dimensioned and positioned so as to transmit the weight of the glazing 3 to the frame 2 and to distribute the forces on the members of rotation or of fixing of the element of window 1. In the case of a sliding frame, the Cl wedges must ensure the transfer of weight at the rolling points.

Peripheral wedges C2 can be provided on the upper cross-member T or on the uprights M of the chassis 2. They are dimensioned and positioned so as to avoid displacement of the glazing 3 in its main plane Pp.

Peripheral safety wedges C3 are provided on the uprights M of the frame 2 and are dimensioned and positioned so as to guard against any possible contact between the glazing 3 and the frame 2.

Securing blocks C4 are provided on the uprights M of the chassis 2 and are dimensioned and positioned so as to limit the stresses on the chassis 2, in particular the stresses in its plane Pp during the operation or handling of the window element E

Side shims (not visible in FIG. 1) are also provided on the uprights M or the cross members T of the chassis 2 and are dimensioned and positioned so as to transmit to the chassis 2 the stressing forces perpendicular to the main plane Pp of the glazing 3. Alternatively, the joint bases or the extruded profiles of rubber or of thermoplastic material, arranged in the rebates of the joinery profiles constituting the frame, making it possible to seal between the glazing 3 and the frame 2, ensure the transmission of forces stress perpendicular to the plane of the glazing 3 and make it possible to dispense with lateral shims.

After the glazing 3 has been placed in the frame 2 according to the desired position and orientation thanks to the different shims, the final fixing and the sealing of the glazing 3 relative to the frame 2 are carried out.

The frame is designed to receive the glazing in the rebates of the joinery profiles constituting its crosspieces and its uprights. The rebates of these joinery profiles must therefore be dimensioned so as to be able to entirely house the shims, the periphery of the glazing over a sufficient length to allow it to be held in position, and the sealing devices between the frame and the glazing. Generally, the useful height of the rebates is between 12 mm and 30 mm depending on the nature and dimensions of the glazing.

The glazing being in abutment against the bottom wall of the rebate of the chassis by means of shims, the chassis will be stressed punctually because of the forces transmitted by the glazing, due to the external stresses received by the glazing, but also to the weight of the glazing that the frame must support. These punctual forces can be significant, in particular in the case of large window elements, the frame must be able not to deform so as not to deteriorate under the effect of these punctual forces, in particular in shear and bending. . The chassis should therefore be designed to be sufficiently resistant, and as its mechanical resistance, in particular to bending and shearing, is linked to its dimensions, these will be relatively large. Thus, and for frames intended to receive such high-weight glazing such as double glazing or triple glazing of large dimensions, the width of its uprights (resp of the crosspieces) according to the direction of the rebate depth, constituting the part structural of the upright or of the crosspiece (excluding rebates) is typically of the order of several tens of millimeters, and typically much greater than 40 mm.

By adding to it the useful height of the rebates, the width of the uprights and crosspieces can reach a value of 80 mm, in particular in the case where the frame is designed to support double or triple glazing, of large dimensions.

Thus, the glazed area of the window element will be reduced, the frame occupying a relatively large area of the window element. Typically, the clear glass, which is the ratio between the unobstructed glass area and the total area of the window element will generally be around 75%.

Therefore, one of the drawbacks of the window elements of the state of the art, is that their glazing clearness is too low to allow a satisfactory arrival of light in the building.

Another drawback is that their appearance is degraded due to the large dimensions of the chassis and the presence of seals visible from the outside.

The objective of the present invention is to overcome the aforementioned drawbacks by proposing a window element with a large amount of glazing without degrading its qualities of insulation.

Another object of the present invention is to provide a window element with an improved appearance.

Another object of the present invention is to provide a window element with a large amount of glazing that is simple to manufacture.

The window element is intended to be mounted in a window installation, such as for example a large sliding window installation. To this end, the window elements are designed to be mounted in a frame, generally consisting of a frame, provided for example for receiving the guide elements of the window element, and of a pre-frame fixed on the fixed parts of the building, such as the ground or the fixed vertical walls of the building, such as the walls, used to secure it. Thus, the frame, namely the projecting frame of the pre-frame is found inside the opening of the building.

A disadvantage of prior art window installations is that their glazing clearness is too low to allow satisfactory light to enter the building.

Another disadvantage of prior art window installations is that their appearance is degraded due to the large dimensions of the frame frame and the presence of seals visible from the outside, which generally requires planning additional siding elements to hide and protect the frame and seals, which increases the costs of window installation.

Another drawback of prior art window installations is that the lower part of the frame of the frame protrudes from the ground by a length such that it can hinder access to the building by this window installation, in particular for People with Disabilities.

The objective of the present invention is therefore to propose a window installation which overcomes the aforementioned drawbacks by proposing a window installation with a significant amount of glazing without degrading its qualities of insulation.

Another object of the present invention is to provide a window installation of improved appearance, not requiring additional facing elements to hide and protect the frame of the frame and the seals.

Another object of the present invention is to provide a window installation which does not hinder access to the building by this window installation, in particular for the disabled.

With reference to FIGS. 4 to 6 and 9 and according to the invention, the window element 10 for 20 buildings comprises:

- double or triple glazing 30, hereinafter designated glazing 30

- A frame 20, comprising uprights M and cross members T, comprising a rebate F on its inner perimeter, with a bottom wall PF and two side walls PL projecting from the bottom wall PF, the rebate receiving the peripheral edge of the glazing 30.

Notably, the edges C of the glazing 30 are supported by means of at least one strip of elastomer, in particular a strip of cellular EPDM, which runs along the edges C of the glazing against the bottom wall PF of the rabbet F of the chassis 20, continuous over the entire inner periphery of the chassis 20.

The term continuous support is understood here to mean that the edges of the glazing are in abutment against the bottom wall PF of the rebate of the frame, by means of said at least one elastomer strip, over 90% to 100% of the periphery of the chassis along the two uprights and two cross members on the chassis.

As shown in Figures 5 and 6 for information, and generally, the glazing 30 may be double glazing. In this case, it comprises two parallel panes 3 li and 31e, each pane being, for example, made of monolithic glass or composed of several sheets of transparent materials, in particular glass or a thermoplastic material, such as plexiglass for example.

In the embodiment shown in FIGS. 5 and 6, and in general the panes are made of laminated glass, the pan 3 li lying towards the interior of the building being thicker (therefore comprising a greater number of sheets of transparent materials) than the window 31e located towards the outside of the building (which therefore comprises fewer sheets of transparent materials).

At least one spacer 32, extending over the entire periphery of the panes, maintains the spacing between the inner and outer panes 3 li, 31e, so that a strip of insulating gas, for example air, can be inserted between the interior and exterior windows 3 li, 31e.

As shown in Figure 9, the glazing 30 may alternatively be a triple glazing. It then comprises three parallel panes 3 li, 31e and 31m, each pane being, for example, made of monolithic glass or composed of several sheets of transparent materials, in particular glass or a thermoplastic material, such as plexiglass for example.

In the example shown in FIG. 9, the panes are made of laminated glass, the panes 3li and 31e being located towards the inside and outside of the building being thicker (therefore comprising more sheets of transparent material) than the window 31m located in the middle part of the glazing, between the interior and exterior windows (which therefore comprises fewer sheets of transparent material).

At least one spacer 32, extending over the entire periphery of the panes, maintains the spacing between the inner and outer panes 3 li, 31e and the middle pane 31m, so that a strip of insulating gas, of air, for example, can be inserted between the interior and exterior windows 3 li, 3 le and the central window 3 lm.

In the example of FIG. 4, and in general, the frame 20 is a part of generally rectangular shape, comprising two vertical uprights M parallel to each other and two horizontal crosspieces T parallel to each other.

The frame 20 comprises at least one rebate F, which advantageously extends continuously along its inner periphery.

A rabbet F can be defined as a groove intended to receive the peripheral edge of the glazing 30. As can be seen in FIGS. 5 and 6, each upright

M and each cross member T of the chassis 20 has a rebate F.

The rabbet F of an upright M or of a cross-member T comprises a bottom wall Pf, designed to receive in support the edges C of the glazing 30, the edges C of the glazing 30 being defined as the outer walls of the windows 3 li, 31e and 31m, of smaller dimensions, perpendicular to the main plane Pp of the glazing 30.

The bottom wall Pf of the rabbet F extends over the entire length of the upright M or of the cross-member T in a plane perpendicular to the main plane Pp of the glazing 30.

The rabbet F also comprises two lateral portions 25 which are parallel to each other, symmetrically distributed on both sides of the bottom wall Pf. The two lateral portions 25 project perpendicularly from the bottom wall Pf towards the interior of the frame 20. The lateral portions 25 protrude in such a length that they prevent, through their internal wall PI, the movement of the panes of the glazing 30, perpendicular to their main plane Pp and that they fully house the connecting elements of the glazing 30 to the frame 20.

The lateral portions 25 of the rabbets F of the uprights M and of the crosspieces T can project from the bottom walls Pf of the uprights M and of the crosspieces of the same length or of a different length.

The rabbets F of the uprights M and of the crosspieces T are provided to be in communication over the entire inner periphery of the chassis 20, in particular at the corners of the chassis 20. For this purpose, as shown in FIGS. 7 and 8, the walls of bottom Pf of the rabbets F of the uprights M and of the crosspieces T have an equal width, the width corresponding to the length between the two interior walls PI of the lateral portions 25 of the rabbets F.

Advantageously, when the uprights M and the crosspieces T of the chassis 20 are designed to be separate parts assembled together to form the chassis 20, the lateral portions 25 of the rabbets F of the uprights M and of the crosspieces T can be bevelled at at least one of the ends of the upright M or of the cross member T.

As shown in FIGS. 5, 6 and 9, at least one strip of elastomer B, in particular a strip of cellular ethylene-propylene-diene-monomer (EPDM), is arranged on the periphery of the glazing 30, so as to cover , at least partially the edges C of the glazing 30.

In the case of double glazing, shown for example in Figures 5 and 6, two bands of elastomer B are provided and are arranged on the periphery of the glazing 30 so as to cover, for example, fully the edges C of each of the windows 3 li, 31e of glazing 30.

In the case of triple glazing, shown for example in Figure 9, two bands of elastomer B are provided and are arranged on the periphery of the glazing 30 so as to cover, for example, partially the edges of the inner windows 3 li and outside

3 the triple glazing 30.

The edges C of the glazing 30 are therefore in continuous abutment against the bottom wall Pf of the rabbet F of the chassis 20 by means of the at least one elastomer strip B. The at least one elastomer strip B is provided for be distributed over the entire periphery of the glazing 30, this support being continuous over the entire periphery of the glazing 30 and therefore over the entire inner periphery of the frame 20. As a result, the forces absorbed by the glazing 30 due to the different external stresses that 'it can undergo, will be transmitted to the chassis 20 distributed over its entire inner periphery. The weight of the glazing 30 will also be transmitted distributed over the entire length of the lower cross-member T of the frame 20.

Through the elastomer strip B, the glazing 30 will therefore be immobilized relative to the frame 20 and will not be able to move along its main plane Pp.

The width of each strip of elastomer B can also be such that they find themselves in lateral abutment against the internal wall PI of the lateral portion 25 of the rebate F. This allows the glazing 30 to stop, in the perpendicular direction in its main plane, provided by the lateral portions 25 of the rabbet F, or provided via the elastomer strip B, preventing the glazing 30 from finding itself in direct contact against the inner wall of the lateral portions 25 of the rabbet F, which could weaken or deteriorate it.

The elastomer strip B therefore advantageously replaces the shims used to ensure the precise positioning and the immobilization of the glazing relative to the frame in the window assemblies of the state of the art.

In addition, in the window elements of the state of the art, the cross members and the uprights of the frame are highly stressed, in particular in bending and shearing at certain points, corresponding to the positions of the shims through which the glazing is resting on the chassis. The crossmembers and the uprights of the chassis must have significant mechanical resistance, in particular to bending and shearing, so as not to deform or deteriorate under the effect of these significant point stresses. The mechanical resistance of the chassis being linked to the thickness of its uprights and its crosspieces, this must be significant, for example of the order of 70 to 80 mm, to ensure sufficient mechanical resistance to the chassis, particularly in the large glazing.

However, in the case of the present invention, the edges C of the glazing 30 are in continuous support over the entire inner periphery of the frame 20. The forces collected by the frame 20 are thus advantageously distributed over its entire inner periphery. As a result, the chassis will not be stressed punctually significantly but uniformly, in particular in bending and shearing, over its entire length, which will generate less significant deformations and will require less mechanical resistance of the chassis, therefore a thickness of its uprights and its crosspieces less, typically of the order of 50 mm (excluding rebate) according to the prior art known in the case of large glazing.

Thus, the surface occupied by the glazing with respect to the overall surface of the window element can advantageously be large, and by comparison with the state of the aforementioned technique using shims. The glazing clear of the window element according to the invention can therefore reach a value of the order of 95%, in particular for large glazing, where the window elements of the state of the art generally reach a value of 75%.

Furthermore, according to the tests carried out by the applicant, a window element according to the invention can have a thermal conductance of between 1.1 and 1.3

W / m ² ° C, which corresponds to the recommended values for good thermal insulation of the building.

According to an advantageous embodiment of the invention, the edges C of the glazing 30 are glued into the rebate F of the frame 20 by a gluing system 26.

As shown in the exemplary embodiments of FIGS. 5, 6 and 9, the bonding system 26 may for example comprise a silicone seal, of the structural type. The bonding system 26 is distributed over the peripheral edges of the glazing 30. The bonding system 26 is provided to be inserted between the inner wall PI of the side wall 25 of the rebate F and the inner 3 li and outer 31e windows of the glazing, and to have a width such that it is fully housed in the rabbet F of the frame 20.

Thus, the bonding element 26 does not cover the part of the glazing 30 located outside the rebate F of the frame 20, and therefore does not reduce the glazing clearness of the window element 10.

The bonding system also makes it possible to ensure the seal between the frame 20 and the glazing 30 of the window element 10.

According to an advantageous embodiment of the invention, each upright M and / or each cross member T of the chassis comprises exterior carpentry profiles 21, 22, and at least one assembly interior profile 23, 27, bracing the exterior profiles 21 , 22, said external profiles 21, 22 and said internal profiles 23, 27 having assembly parts, of complementary shape, mutually engaging, to ensure the assembly between the internal profile (s) and the exterior profiles.

As shown in the exemplary embodiments of FIGS. 5 and 6, the uprights M and the crosspieces T result from an assembly of joinery profiles 21, 23; 22, 27.

The crosspieces T result from the assembly of at least three joinery profiles 21, 23.

Two exterior carpentry profiles 21, made for example of metal, in particular bronze or an alloy mainly based on bronze, constitute the lateral parts of the cross member T. These two exterior carpentry profiles 21 are symmetrical with respect to the median plane Pm of the frame 20 and include the lateral portions 25 of the rabbet F.

At least one interior joinery profile 23, made for example of thermoplastic material, for example polyamide, is provided to be interposed between the two extensible joinery profiles 21. The interior joinery profile 23 has assembly parts intended to come in mutual engagement with correspondingly shaped assembly parts formed on the exterior joinery profiles 22. The interior joinery profile 23 is a bracing element in that it maintains the exterior joinery profiles 22 by fixing the distance which separate them.

The interior joinery profile 23 is designed to be arranged parallel to the edges C of the glazing 30 and to contain the bottom wall Pf of the rebate F and the outer peripheral wall of the frame 20.

The uprights M also result from the assembly of at least three, or even at least four joinery profiles 22, 27. Two exterior joinery profiles 22, made for example of metal, in particular bronze or an alloy mainly based on bronze , constitute the lateral parts of the upright M. These two external carpentry profiles 22 are symmetrical with respect to the median plane of the chassis 20 and include the lateral walls 25 of the rebate F.

At least one interior carpentry profile 27, advantageously at least two interior carpentry profiles 27, made for example of thermoplastic material, in particular polyamide, are provided to be interposed between the two exterior carpentry profiles 22. The interior carpentry profiles 27 have assembly parts intended to come into mutual engagement with correspondingly shaped assembly parts formed on the exterior carpentry profiles 22. The interior carpentry profiles 27 are bracing elements in that they hold the profiles of exterior carpentry 22 by fixing the distance between them.

The first interior carpentry profile 27, located near the glazing 30 is designed to be arranged parallel to the edges C of the glazing 30 and to contain the bottom wall Pf of the rebate F. The second interior carpentry profile 27, located near of the outer peripheral wall of the chassis 20 is provided to be arranged parallel to the first interior carpentry profile 27 and to contain the peripheral external wall of the chassis 20. In the variant where the upright comprises only an interior carpentry profile 27, that this is arranged parallel to the edges C of the glazing 30, and contains the bottom wall Pf of the rabbet F and the outer peripheral wall of the frame 20.

The combination of two exterior carpentry profiles 21, 22 made of metal arranged on either side of one or more interior carpentry profiles 23, 27 made of thermoplastic material makes it possible to provide a thermal break at the level of the chassis 20 , between the interior and exterior of the building, thermoplastic materials having a lower thermal conductivity than metallic materials.

According to an advantageous embodiment of the invention, the thickness ePs of the structural part Ps of the sleepers T of the frame 20, excluding the rabbet F, in the vertical direction perpendicular to the bottom wall Pf of rabbet F, is less than 40 mm, preferably less than 20 mm.

As shown in the embodiment of the invention of FIG. 5, the cross-member T of the chassis comprises a rebate F intended to receive the edges C of the glazing 30 and a structural part Ps, intended to ensure the mechanical resistance of the cross-member T, and possibly its guidance in a frame 50, and possibly receiving other functional elements of the frame 20, such as sealing means 63 or guide means 61 of the window element 1 in a frame 50.

The thickness ePs of this structural part Ps is defined as the distance separating the wall of the rebate F parallel to the bottom wall Pf of the rebate F, the most distant from the edges C of the glazing 30 from the wall of the structural part Ps , which can advantageously be a wall of the exterior joinery profiles 21, parallel to the bottom wall Pf of the rebate F, the most distant from the edges C of the glazing 30.

The structural part Ps is designed to provide sufficient mechanical resistance, in particular in bending and shearing, to the cross members T of the chassis 20, so that they do not deform and do not deteriorate due to the forces mentioned above. However, the mechanical resistance of a cross-member T of the chassis will depend on the thickness ePs of this structural part Ps. As we have seen previously, the mechanical resistance of the chassis, and in particular of its cross-members, must be less, because the forces that it will have to collect are distributed over its entire periphery, and not in certain local (or punctual) areas as in the state of the art using shims. Thus, the thickness ePs of the structural part may be minimum, considerably less than that necessary for the frames of the state of the art, when the glazing is fixed in abutment on wedges, and according to the state of the known technique.

Advantageously, this thickness ePS therefore does not exceed 40 mm, and preferably, it does not exceed 20 mm, which allows the glazing 30 to occupy most of the surface of the window element 10, and therefore to maximize the clear glass.

Depending on the clamping force applied between the nuts 29 and the rods 28, the connection between the ends of the uprights M and of the crosspieces T may be more or less stressed, in particular in compression in order to stiffen the chassis 20 and ensure continuous support of the edges C of the glazing 30 against the bottom wall Pf of the rebate F.

A support plate 24 can advantageously be interposed between the nuts 29 and the outer peripheral wall of the frame 20, which is the outer wall of the interior carpentry profile 23 of the cross member T. The support plate 24 allows the force to be distributed. compression on a certain surface of the end of the outer peripheral wall of the cross member T of the chassis 20, so that this compression force does not damage the middle carpentry section 23 of the cross member T.

Two additional screws VT cooperating with holes made in the middle carpentry profile 23 can be provided to fix the support plate 24 to the outer peripheral face of the middle carpentry profile 23.

Thus, according to an exemplary embodiment, eight rods 28, sixteen nuts 29 and four plates 24 will be used to secure the ends of the uprights M to the ends of the cross members T of the chassis 20.

Alternatively, the rods 28 can be housed inside the cross members T of the chassis 20, and in particular in through holes formed along the interior carpentry profile 23, inside of it, cooperating with corresponding through holes. formed in an interior carpentry profile 27 of the M-pillar. The rods 28 will cooperate, at their threaded ends, with nuts 29, in order to achieve the fixing between the M-pillars and the T-beams of the chassis 20.

In this alternative, a support plate 24 may advantageously be interposed between the nuts 29 and the outer peripheral wall of the frame 20, which is the outer wall of the interior carpentry profile 27 of the M-pillar.

a step 104 for fixing the chassis 20 to the glazing 30, so that the edges C of the glazing 30 are found in continuous support over the entire inner periphery of the chassis 20, by means of at least one strip of elastomer of constant thickness, in particular a strip of cellular EPDM, which runs along the edges C of the glazing against the bottom wall PF of the rebate F of the frame 20.

During step 101 of supplying a frame 20, the uprights M and the crosspieces T are advantageously manufactured separately. The different functional parts of the uprights M and of the crosspieces T can then be produced, for example by machining. A dimensional check of the chassis 20 can optionally be carried out during the entire step 101 of supplying the chassis 20 in order to ensure that its dimensions correspond to those provided.

During step 102 of determining the dimensions of the glazing 30, the dimensions, and more particularly the width and the height of the glazing 30, are determined which will allow the turn to be fully received in the frame 20 and to be in continuous support over the entire inner periphery of the frame 20, by means of at least one elastomer strip B. It is thus possible, for example, to determine the dimensions, in particular the width and the height of the frame 20 along its inner peripheral wall, in possibly relying on the dimensional control carried out during step 101 of supplying the frame 20. It is advantageous to determine the width and the height of the glazing 30 as having to be equal to the width and the height of the frame 20 along its inner peripheral wall, also taking into account the thickness of the elastomer strip B, this thickness having to be subtracted from the width eur and the height of the glazing 30.

During step 103 of supplying the glazing 30, the glazing 30, which may be double or triple glazing, is produced by any technique for manufacturing double or triple glazing known to those skilled in the art. The edges C of the glazing 30 are then rectified, for example by means of a diamond disk, so that its dimensions, and in particular its width and its height correspond to those determined during step 102 of determining the dimensions. glazing. The dimensional manufacturing tolerances during the rectification of the edges C of the glazing 30 are advantageously +/- 1 mm, and preferably +/- 0.5 mm. An elastomer strip B, in particular a cellular EPDM strip, is then placed on the edges C of the glazing 30, so as to extend over the entire periphery of the glazing 30. The elastomer strip B, having a thickness of a few millimeters, which can be reduced when the strip of elastomer B is compressed, the dimensional differences between the glazing 30 and the frame 20, will be compensated by this strip of elastomer B, so that the glazing 30 will be in continuous support against the bottom wall Pf of the rabbet F of the chassis 20, by means of the elastomer strip B.

During step 104 of fixing the frame 20 to the glazing 30, the glazing 30 can for example be placed flat, for example on trestles. A device for controlling the flatness of the glazing 30, a level for example, can optionally be used to ensure that the flatness of the glazing is maintained during the step 104 of fixing the frame 20 to the glazing 30. The frame 20 can then be fixed on the glazing, so that the edges C of the glazing 30 are found in continuous support, over the entire inner periphery of the frame 20, against the bottom wall Pf of the rabbet F.

According to an advantageous embodiment of the invention, during step 104 of fixing the frame 20 to the glazing 30, a bonding system 26 is used to secure the edges C of the glazing 30 in the rebate F of the chassis 20.

During the step 104 of fixing the chassis 20 to the glazing 30, when the chassis 20 has been positioned on the glazing 30, so that the edges C of the glazing 30 are found in continuous support, over the entire inner periphery of the chassis 20 , against the bottom wall Pf of the rabbet F, a bonding system 26, which may for example comprise a structural silicone gasket, is distributed over the entire periphery of the glazing 30, using for example a spray gun injection, so as to be inserted between the inner wall PI of the side wall 25 of the rebate F and the inner panes 3 li and outer 31e of the glazing. So that the bonding system 26 is fully housed in the rebate F of the frame 20, the excess which would be on the part of the glazing 30 outside of the rebate F is removed, before drying of the bonding system 26 for its setting. The frame 20 and the glazing 30 are thus secured.

According to an advantageous embodiment of the window element manufacturing method according to the invention, each upright M and / or each cross member T of the chassis 20 comprises external carpentry profiles 21, 22, and at least one internal profile 23, 27 assembly, bracing the outer profiles, said outer profiles 21, 22 and said inner profiles 23, 27 having assembly parts, of complementary shape, mutually engaging, to ensure the assembly between the profile (s) ) interior (s) 23, 27 and exterior (s) 21, 22.

The different joinery profiles 22, 24; 23, 27 are therefore produced separately, by any manufacturing technique known to a person skilled in the art, then assembled to form the uprights M and the cross members T of the chassis 20.

Thus, the crosspieces T and the uprights M of the frame 20 can be assembled only just before the step 104 of fixing the frame 20 on the glazing, which will facilitate their handling at the place of manufacture of the window element.

According to an advantageous embodiment of the method for manufacturing a window element according to the invention, the thickness of the structural part, excluding the rebate in the vertical direction perpendicular to the rebate bottom wall, of the cross members of the frame, is less than 40 mm, preferably less than 20 mm.

The cross members T of the frame 20 will therefore have smaller dimensions and weight than those of the frames 2 of the prior art, in particular in the case of large glazing. Their handling up to the place of manufacture of the glazing element will therefore be easier.

According to an advantageous embodiment of the invention, the frame 20 results from an assembly of joinery profiles, forming the uprights M and the cross members T of said frame, the frame 20 results from an assembly of joinery profiles 21, 23 ; 22, 27, forming the uprights M and the cross members T of said chassis, the chassis 20 comprising at least one compression device 24, 28, 29 comprising at least one mechanical connection 28, 29 extending internally along a sleepers T according to a first alternative, or one of the uprights M according to a second alternative, said at least one mechanical connection 28, 29 connecting by its ends supports 24 of said compression device, said supports 24 being respectively secured to said M uprights, according to said first alternative, or T cross members according to the second alternative, at the ends of said M uprights, according to said first alternative, or T cross members according to the second alternative, and during step 104 of fixing the chassis 20 on the glazing 30 of the process, the joinery profiles of the uprights M and the joinery profiles of the crosspieces T are assembled at their ends, and during the pr process of manufacturing a window element, said at least one mechanical connection 28, 29 is stressed in tension to ensure that the ends of the joinery profiles of said intermediate part of the frame 20 are held under stress against the corresponding ends of the joinery profiles , arranged on either side of said intermediate part, belonging to said uprights M, according to said first alternative, or to cross members T according to the second alternative.

During the step 104 of fixing the frame 20 to the glazing 30, after the possible flat arrangement of the glazing 30, the uprights M and the cross members T of the chassis 20, are arranged around the glazing 30, in a position which corresponds substantially at their final position. Rods 28, for example metal rods, for example at least two in number, in particular four in number, are then introduced into holes passing through T27, for example at least two in number, in particular four in number, uprights M and in holes through T23 of the crosspieces T, nuts 29, for example at least two, in particular four in number, being screwed onto the ends of each rod 28, which can be threaded for this purpose.

Depending on the clamping force applied between the nuts 29 and the rods 28, the connection between the ends of the uprights and the crosspieces can be more or less stressed, in particular in compression in order to stiffen the chassis 20 and ensure the continuous support of the edges C of the glazing 30 against the bottom wall Pf of the rebate F.

A support plate 24 can advantageously be interposed between the nuts 29 and the outer peripheral wall of the frame 20, which is the outer wall of the interior carpentry profile 23 of the cross member T.

According to an exemplary embodiment, eight rods 28, sixteen nuts 29 and four plates 24 will be used to secure the ends of the uprights M to the ends of the cross members T of the chassis 20.

Alternatively, the rods 28, for example at least two in number, in particular four in number, can be housed inside the cross members T of the chassis 20, and in particular in through holes T27, for example at least the number of two, in particular four in number, formed along the interior carpentry profile 23, inside thereof, cooperating with corresponding through holes formed in an interior carpentry profile 27 of the M-pillar. The rods 28 will cooperate , at their threaded ends, with nuts 29, for example at least two in number, in particular four in number, in order to achieve the fixing between the uprights M and the cross members T of the chassis 20.

The method of manufacturing the window element 10 according to the invention therefore does not require tedious operations for handling the glazing 30, which is generally the heaviest part of the window element 10, in particular in the context of 'a glazing 30 of large dimensions. Indeed, to manufacture a window element 1 of the prior art, it is necessary to use several manipulations of the frame 3 to position it in the appropriate position in the rebate F of the frame 2, by means of shims.

Likewise, the uprights M and the crosspieces T being assembled once positioned around the glazing, manipulation of the already assembled chassis 20, which can prove to be tedious, the chassis 20 may have a significant weight, in particular in the case of glazing of large dimensions, will not be necessary.

Naturally, other embodiments could have been envisaged by the skilled person without departing from the scope of the invention as defined by the claims below.
