Description

CLOSING CHASSIS FOR BUILDINGS, WINDOW OR DOOR TYPE
WINDOW WINDOWS, SLIMMED, OPENING (S) HIDDEN
The present invention relates to a closing frame for a building, type window or French window with striking, and, more particularly, with hidden opening (s).

 These hidden opening frame (s) have the particularity of being, when viewed from the front and from the outside, a fixed frame.

Indeed, the frame of the opening (s) is hidden by the external wall of the frame and by the external wall of the counterbone if necessary, that is to say that this or these opening frames are not visible from the 'outside.

 These chassis are relatively expensive when made entirely of aluminum. The present invention provides a frame with hidden openings which allows, in particular by the choice of materials used, to obtain a relatively inexpensive product.

 This choice of materials and the constructive solutions according to the invention also allow wide aesthetic possibilities, for example the ability to choose different colors and shades for the interior and exterior of the building.

 The constructive solutions adopted also make it possible to accentuate the delicacy of the frames of the opening elements, thus providing a much larger amount of glazing than usual.

 The chassis according to the invention comprises - on the one hand, at least for the part of the frame located outside the building, that is to say the part subjected to weathering, a wall made of aluminum profile and , - on the other hand, at least for the part located inside, one or more opening frames, made of thermoplastic material of the PVC or other type.

 According to a first embodiment, the frame consists of two aluminum profiles, connected together by means of an insulating system which achieves a thermal break between the profile constituting the external wall exposed to the weather and the profile constituting the wall internal building.

According to an alternative embodiment, the frame consists of an outer wall made of aluminum profile, and an inner wall made of thermoplastic material of the PVC or other type, these two wall elements forming said frame being assembled by all suitable means: screwing, gluing, riveting, crimping
Still according to the invention, in the case of a window or window-type window frame with a double-leaf strike, one of the opening frames comprises, fixed on its central upright, a counter-link for which on the one hand , the external part at least, that is to say the part exposed to the weather, is made of a single aluminum profile, this profile improves the resistance by greater inertia and masks the glazing beadings of each amount of the opening elements, which openings are therefore invisible from the front, seen from the outside, and for which, on the other hand, the internal nude is identical to that of the frame, partially masked by the internal face of the peripheral edge of the adjacent sash frame , which internal bare receives the seals arranged on the internal face of said peripheral edges of the two frames, and, moreover, the visible part of which naked between said frames, is located in the middle of the central upright formed by said opening.

 According to another arrangement of the invention, the frames of the opening elements are prepared from elements coming from the same profile, assembled with cut tabs at 45 "or by a corner piece, which profile has a fitted rebate to accommodate and allow the fixing by screw or other of the counterbone, on one of the central uprights of said frames.

 According to a first embodiment of the invention, the double butted consists of two parts made of aluminum profile, assembled together by means of an insulating system forming a thermal break: - an external part exposed to the weather, which hides the glazing beadings of the opening and - an internal part which is fixed in the rebate of one of the uprights of said opening.

According to an alternative embodiment, the double-butted consists of two parts made of different materials: - an external part made of aluminum profile, exposed to the weather, which masks the glazing beads of the opening, and - an internal part made of thermoplastic material, of the kind PVC, of the same nature as the profiles used for the confection of opening frames, which internal part is assembled in the rebate of the central upright of one of said opening elements, said internal and external parts are assembled together by any appropriate means: screwing, gluing, riveting, crimping
According to another arrangement of the invention, the internal profile of the buttress, made of thermoplastic material or aluminum, has a technical groove identical to the groove formed in the frame of the opening elements, to possibly accommodate, in place of the latter, components of the opening mechanism.

 Still according to the invention, the profile constituting the internal part of the buttress, comprises means which make it possible to position it in a precise manner in the rebate of the upright with which it is associated, which means consist, on the one hand, of a part which extends the face of said profile which is in abutment in the bottom of said rebate, which leg is in abutment in the angle of the latter, against its internal side and, on the other hand, at least one perpendicular leg and in projection relative to said face of the profile, which is housed in the technical groove of said upright to wedge said profile constituting the internal part of the buttress before immobilizing it and fixing it on said upright by means of screws.

 According to another arrangement of the invention, the external part of the buttress has a width which is of the order of five times the height of the rebate of the opening frames, which receives the glazing; the total width of the central upright, inside the building, being of the order of six times said height of the glazing rebate, providing a significant amount of glazing at the opening frames. This feature gives the chassis great finesse due to the particularly small size of the central upright and, in general, of the frame.

 The frame according to the invention can be, for example, a window or window with one leaf or two leaves, opening in the French style, that is to say opening on hinges and towards the interior of the building, or alternatively swing or bellows. The windows may optionally be adjacent to each other and in addition, possibly with fixed glazing, to form a frame made up of several windows.

According to the invention, in the case of a window or French window with two leaves and a fixed glazing, the frame comprises a fixed intermediate upright interposed between one of the opening and said fixed glazing, which intermediate upright is constituted as the frame, an external wall formed of a profile made of aluminum and an internal wall formed either of a profile made of aluminum and assembled with the profile of the external wall by an insulating system, or of a profile made in plastic material of the PVC or other type and assembled to said profile of the external wall by any suitable means: screwing, gluing, riveting, crimping
Still according to the invention, the intermediate upright is symmetrical with respect to a vertical plane perpendicular to said chassis and the internal profile of said upright comprises a groove which receives a glazing bead to allow the fixing of the fixed glazing, which groove is identical to that which is arranged. on the frame and in particular on the profile constituting the internal wall of the latter and in which the groove are housed the other glazing beads for fixing said fixed glazing.

 According to an alternative embodiment, the intermediate upright comprises, on the side of the fixed glazing, a groove with a U-section forming a rebate for housing said glazing, the sides of which are materialized by the side or rim of the profile constituting the external wall, and by the profile constituting the internal wall; this profile constituting the internal wall comprises a tubular part which extends from the side of the glazing practically to the level of the end of the flank or rim of the profile constituting the external wall and this internal profile comprises, on the side of the opening, a groove which corresponds to that of the frame, which groove is used on the latter, for the reception of the glazing beads for fixing the fixed glazing.

 In general, the frame and the frame of the window openings are relatively thin. The closing system takes up little space; this system corresponds, for example, to that commonly used for conventional wooden or PVC frames. But in the case of a French window, the closing system can be more voluminous if a lock is used.

 Thus, according to another arrangement of the invention, in the case of a window frame type carpentry comprising a lock, the opening frame is provided at its closing amount, with an additional amount which allows the reception of a lock, which additional amount is provided with a positioning tab on the primary amount and it is fixed by any appropriate means on the internal face of the latter, which additional amount is for example made up on the one hand , for the internal part, of a profile made of thermoplastic material, the section of which is in the form of a tubular L to constitute the rebate for receiving the glazing, and, on the other hand, for the external part, of a profile in aluminum which takes place in the rebate of the primary frame of the opening and seals with the seal of the glazing bead of the latter, which aluminum profile, fixed by any appropriate means on said thermoplastic profile, has a suitable groove folded to accommodate and lock another glazing bead in aluminum profile also which, by means of a seal, keeps the glazing in the rebate of said additional upright.

 Certain types of chassis can be fitted with a ventilation system, that is to say, include air passage openings, protected by one or more air intake vents, possibly respecting an acoustic reduction and which can also be possibly self-adjusting, associated or not with a CMV, i.e. controlled mechanical ventilation.

 This ventilation can be arranged at the level of the frame or the openings, above or below.

 According to the invention, in the case of ventilation arranged at the cross member of the frame, the frame comprises an additional cross member which replaces the primary cross member to accommodate a fixed glazing or an opening, and it comprises for example on the one hand, an external aluminum wall which extends the primary wall leaving a passage relative to the latter for ventilation, which external wall provides sealing with the opening or fixed glazing, and, on the other hand, an internal wall which is made either of aluminum assembled with or without a thermal break system with said external wall, or of thermoplastic material of the PVC or other type, assembled by any appropriate means with said internal wall, which internal wall is present under the shape of a box assembled on the primary cross member and in particular in the technical groove for receiving the internal glazing beads, which internal wall has orifices air passage, protected by one or more vents.

 According to another arrangement of the invention, in the case of ventilation provided at the cross member of the opening frame, the frame comprises a complementary cross member which replaces this cross member of the frame for fixing the glazing, which complementary cross member comprises, on the one hand, for example, an internal part with an L-shaped section, tubular, forming the new rebate for receiving the glazing, which internal part is positioned by means of a tab against the lateral wall of the rebate of the primary cross member, and it is fixed to the internal face of the latter by any suitable means, and, on the other hand, an external part made of aluminum profile fixed to the internal part by all appropriate means, which rests on the battée seal of the glazing bead of the primary cross member, which external part has a groove to accommodate another glazing bead also in aluminum profile, which is used to maintain the glazing in said new rebate, which internal and external parts comprising air passage openings covered and protected by one or more mouths.

 Still in the case of a French window, the lower part may consist of an opaque filling panel made for example of composite material.

 The separation between the panel and the glazing is carried out by means of a horizontal crosspiece consisting on the one hand, of an internal profile in thermoplastic material with T-section forming two rebates, one for accommodating said lower panel, L 'other to accommodate said glazing, and secondly, at least one external profile made of aluminum which forms glazing bead and is fixed on said internal profile by interlocking, clipping, screwing or other.

 Still according to the invention, the system for joining the profiles made of aluminum, as well for making the frame, the counter-beam, or the intermediate upright, is formed of a pair of straight bars whose ends, in the shape of a tail. -d'ondonde, are crimped in grooves of the same shape, arranged on the opposite faces of said profiles, which bars are made of any suitable material and in particular PVC because of the relatively attractive cost of this material and also because of its great ease of implementation. These bars themselves ensure the behavior between the two aluminum profiles and participate in the rigidity and resistance of this assembly of profiles. These bars can also be interconnected by at least one wall which forms an insulation screen between the profiles.

The profiles and bars are assembled by crimping. It can also be preceded by a bonding operation.

 According to another arrangement of the invention, one of the bars, in particular the bar which is normally visible, on the chassis when it is placed, further comprises a mask formed by a veil whose cross section is such that it occupies the visible cavity left between the assembled profiles, in particular allowing protection of the corresponding bar against all types of aggression and / or damage.

 According to the invention, the web can receive, at the outlet of the die, a deposit which forms a coating, the color of which may be different from that of the extruded material.

 According to a variant of the invention, the veil is obtained by coextrusion with a material, the color of which may be different from that of the bars, in order to adapt the color of said veil to that of the profiles to be assembled, for example.

 According to another arrangement of the invention, the assembly of the profiles made of aluminum and of thermoplastic material of the PVC or other type, can be carried out according to a mode which is similar to the mode of assembly of the thermal break bars. on aluminum profiles. The profile in thermoplastic material may include at least one dovetail-shaped stud, which stud cooperates with a groove of equivalent shape arranged on the internal face of the profile made of aluminum. The two are assembled by crimping, possibly with a prior bonding operation.

 According to another arrangement of the invention, the connection between the aluminum profiles and the plastic profiles of the PVC or other kind, is effected by means of at least two studs, which studs, in the shape of a tail dovetail, undergo, during the manufacture of said thermoplastic profiles, at the outlet of the die and conforming, a calibration and machining operation by means of a train of cutters so as to obtain a rigorous geometry of said tenons with a setting to the coast , to facilitate threading of said thermoplastic profiles into said aluminum profiles and to obtain good positioning and good assembly with respect to each other during the crimping operation.

 According to another arrangement of the invention, the internal and external walls of the double butted of a window or French window with two leaves, include snap-fastening and fixing means of plugs forming seals, of variable shade, which ensure, at each end, the continuity of the seal between said counterbone and the upper and lower cross members of the frame.

 Still according to the invention, the openings made of thermoplastic material of the PVC or other type, have on their periphery, facing outwards, a groove which makes it possible to accommodate the glazing beads, which glazing beads are hidden when said opening windows are closed, according to the case by the rim of the outer wall of the frame, by the rim of the buttress, by one of the sides or rims of the outer wall of the intermediate upright, which glazing beadings consist of a rigid piece of variable shade with L-shaped section made of thermoplastic material of the PVC or other type, and of a coextruded part of variable color also but uniform to form both the glazing seal and the battée seal.

 The invention will be further detailed with the aid of the following description and the appended drawings, given for information only, and in which - FIG.

 The closures shown in FIGS. 1 and 2 generally comprise a frame 1, openings 2 and 3, the opening 3 being partially shown, on the side of its central upright.

 The frame shown in Figure 1 consists of two sections made of aluminum: a section 4 forming the outer wall which is subjected to the weather and a section 5 forming the inner wall, on which the leaf 2 is articulated.

 The frame 1 is shown mounted on a wall. Depending on the type of wall, that is to say with or without lining, the shape of the sections 4 and 5 constituting the outer wall and the inner wall respectively, may change.

 These two profiles 4 and 5 are for example joined and assembled by means of a junction system 6 detailed below, which is made of thermoplastic insulating material of PVC type or other, to effect a thermal break between said aluminum profiles .

 The closures shown in Figures 1 and 2 are of the hidden opening type, that is to say that the structure of the opening is not visible from the outside, seen from the front. The structure of the openings 2 and 3 is in fact hidden by the peripheral rim 7 of the profile 4 constituting the outer wall of the frame 1, and also by the profile detailed below, constituting the external part of the counter-beam 8.

 The opening 2 consists of a frame 9 made from elements of the same profile, that is to say that these elements have an identical section for the four sides of said frame. These profiles are made of thermoplastic material of the PVC or other type.

 This frame 9 is fixed by means of hinges 10 to the profile 5 of the frame 1.

 The glazing unit It is housed in a rebate 12 of the frame 9, which rebate is closed by means of a glazing bead 13 with an L-shaped section, which is snapped into a cavity 14 arranged on the external periphery of said frame 9.

 This glazing bead 13 is made up of an L-shaped section profile, made of rigid thermoplastic material of the PVC type with variable tint; it comprises a seal 15 obtained by coextrusion and also of variable, but uniform shade, forming both a glazing seal and a battée seal, the latter being in contact with the end of the rim 7 of the profile 4 constituting the external wall of the frame 1.

 The seals of the openings are sealed on the outside with the seal 15 of the glazing bead 13, and on the inside with a seal 16 mounted on the internal face 17 of the peripheral rim 18 of the frames 9. This seal 16 is in contact with on the one hand, with the internal face of the profile 5 constituting the internal wall of the frame 1 and, on the other hand, with the internal bare part of the buttress 8.

 The opening 3 is made as the opening 2 with a frame completely identical to the frame 9, that is to say a frame made up of elements of the same profile. The elements forming the frames 9 are assembled by cutting tabs at 45C or by means of corner pieces.

 The two frames 9 are produced by means of the same profiles in thermoplastic material of the PVC type. The frames of the openings 2 and 3 are therefore perfectly identical at the start, except that one of them includes the machining operations to accommodate the operating handle; this design allows for significant production gains.

 The assembly of the glazing 11 housed in the rebate 12 of the frame 9 of the opening 3, is carried out in the same way as for the opening 2, by means of the same glazing beads 13.

 The central upright of the opening 3 is equipped with the counter-beat 8. This counter-beat 8 is fixed by screws 19 on the central upright of the opening 3 and in particular in the rebate 20. The rebate 20 is arranged around the entire periphery of each frame 9. It is delimited by the face 17 situated in a plane parallel to that of the frame, and by the face 21 which is perpendicular to said face 17. The face 21 is divided by a groove 22 which receives the elements of the mechanism closure not shown in this figure.

 The counter-beat 8 consists, in FIG. 1, of the section 24 which forms the external wall subjected to the weather, and of the section 25 which forms the internal wall.

These two profiles are made of aluminum and they are joined by the structure 6 forming a thermal break.

 The profile 24 has a symmetry with respect to the median vertical plane of the openings 2 and 3. This profile 24 consists of a tubular central part 26 whose section is similar to a trapezoid, and of the sides or flanges 27 arranged on one side and on the other of said median plane; the ends of said flanges 27 are in contact with the seals 15 of the glazing bead 13, like the flange 7 of the profile 4.

 The profiles 24 and 25 of the buttress 8 also include means which make it possible to snap on and fix plugs, not shown, forming seals, at each of their ends, which plugs ensure continuity of the seal; they are in contact with the lower and upper crossmembers of the frame 1. The color of these plugs is chosen as required.

 The profile 24 of the double-leaf conceals the openings 2 and 3 by hiding the structure of the latter.

 The internal profile 25 is in the form of a tubular profile whose central section is rectangular. This profile has a face 28 which acts as a sealing face since it is in contact with the seals 16 of the frames 9 of the openings. This face 28 constitutes the internal bare of the buttress 8. This bare 28 is identical to that of the frame 1 but it receives, at the level of the central upright formed by the two openings, the two seals 16 which are each arranged on the internal face 17 said openings. The visible part of the bar 28, between the edges 18 of the two opening frames, is located in the middle of the central upright formed by said opening elements.

 This profile 25 is off-center with respect to the median plane of the profile 24; it is housed in the rebate 20 of the central upright of the opening 3. The wall 30 of the profile 25, which is perpendicular and contiguous to the face 28, is supported on the face 21 of the central upright of the opening 3. This wall 30 extends beyond the face 28 by a first tab 32 which bears on the internal face 17 of the rim 18 of the central upright of the opening 3, which internal face 17 is perpendicular to the face 21 and forms the rebate 20. The tab 32 adjusts the space between the internal face 28 and the face 17, that is to say that it regulates the crushing of the seal 16 of the frame 9 of the opening 3 on the section 25 of the double-butted.

 The wall 30 has a second tab 34, projecting, perpendicular to said wall 30. This tab 34 is supported on the internal surface of the technical groove 22 arranged set back from the face 21, so as to wedge the profile 25 in the rebate 20. The profile 25 is assembled on the central upright by means of screws 19.

 A groove 35 is provided on the profile 25 of the counter-foothold, facing the groove 22 arranged in the central upright of the opening 2.

 Note, in Figure 1, the particularly compact aspect of the central upright formed by the openings and the lateral upright of the chassis.

 Starting from a rebate height Hf for the rebate 12 in which the glazing 11 is housed, the central upright has a total width Lm which is of the order of six times said height Hf.

 The width Lc of the external wall of the buttress 8, is slightly greater than five times the height Hf.

 It results from these constructive provisions and this arrangement, a particularly important glazing clear.

 FIG. 2 represents an alternative embodiment in which the frame 1 consists of a section 4 'made of aluminum forming the external wall and of a section 45 made of thermoplastic material of the PVC type, like the material used for the openings 2 and 3, forming the internal wall.

 The assembly of the sections 4 'and 45 is carried out by all types of means and in particular screwing, gluing, riveting or crimping as detailed below.

Crimping for example can make it possible to have a profile 4 'strictly identical to profile 4 of the embodiment of FIG. 1.

 The section 45 has a square section with a tubular part 46 linked to the section 4 ′ and also a tubular part 47, which is located inside the building and which receives the hinges 10.

 The frames 9 of the openings 2 and 3 shown in FIG. 2 are identical to those of the openings 2 and 3 in FIG. 1.

 The counterattack 8 can be

 The lug 32 ′ allows the part 60 to be wedged in the rebate 20 and to adjust the crushing of the seal 16 in cooperation with the lug 34 ′ which locks said part relative to the edge of the groove 22.

 The profile 55 includes, on the tubular part 60, a groove 35 'which is the replica of the technical groove 22 arranged in the central upright of the opening 3. The bottom of this groove 35', like that of the groove 35, Figure 1, is drilled to allow the passage of the assembly screws.

 FIG. 3 represents a glazed fixed part which completes the chassis partially represented in FIG. 1.

 The complementary glazing 71 is arranged in a rebate 72, between the frame 1 and a fixed complementary upright 73 on which the frame 9 of the opening 3 is articulated.

 The complementary upright 73 comprises an external wall made up of an aluminum profile 74 and an internal wall made up of another aluminum profile 75 on which is fixed the hinge 10 of the frame 9 of the opening 3. The two profiles 74 and 75 are for example interconnected by means of the junction system 6 detailed below, which serves as thermal break.

 The profile 74 may have an external shape identical to that of the shape adopted for the profile 24 constituting the external wall of the buttress 8.

 The flanks or flanges 77 of the profile 74 have, at each of their ends, a groove 78. On one side, this groove 78 is open, towards the glazing bead 13, so as to be in contact with the battue joint 15 and, from the on the other hand, said groove 78 has a seal 79 which is in contact with the glazing 71.

 The profile 75 has a groove 80 arranged to receive a glazing bead 83 which holds the glazing 71 by means of a seal 82. The glazing bead 83 consists of a profile made of aluminum with U-shaped section, which is clipped into the groove 80. This groove 80 corresponds to the groove 80 arranged over the entire periphery of the internal wall 5 of the frame 1.

 The groove 80 of the profile 5 of the frame 1 also accommodates glazing beads 83 which hold the glazing 71 in abutment against the edge 7 of the profile 4 which forms the external wall of said frame.

 The profiles 74 and 75 can advantageously be symmetrical with respect to a vertical median plane perpendicular to the chassis.

 FIG. 4 shows, like FIG. 3, a glazed fixed part associated with the chassis which is represented in FIG. 2.

 As previously, in FIG. 3, the fixed part consists of a glazing 71 housed in the rebate 72 of the frame 1 and of the fixed intermediate upright 73 '.

 The frame 1, as in the case of FIG. 2, is mixed, that is to say made up of a profile 4 ′ in aluminum and a profile 45 made of thermoplastic material.

 The fixed upright 73 ′ is of the same type, that is to say mixed, consisting of a profile 84 made of aluminum for the external part and a profile 85 made of thermoplastic material of the PVC or other type, for the part internal. The two sections 84 and 85 advantageously have a vertical plane of symmetry, perpendicular to the chassis. These two sections are also assembled by any appropriate means as detailed above.

 The profile 84 is arranged as previously in Figure 3, with grooves 78 at the ends of its flanges 77. One of the grooves is open on the battue joint 15; The other groove is provided with a seal 79 which seals with the glazing 71.

 Profile 84 improves the resistance of the intermediate upright, due to its inertia.

 This peculiarity is also found at the level of the buttress where the profile 24 ′ is associated with a profile 55 made of thermoplastic material. The resistance to bending of the central upright formed by the openings 2 and 3 is thereby significantly increased.

 The profile 85 has a groove 86 arranged to receive and fix an internal glazing bead 87 tubular, also made of thermoplastic material of the PVC or other type, with, preferably, a glazing seal 88 obtained directly by coextrusion.

 The groove 86 arranged on each side of the profile 85 is found identically on the frame 1 and in particular on the profile 45 where there is in the same way an internal glazing bead 87.

 FIG. 5 represents an alternative embodiment of the intermediate upright 73 which corresponds to the embodiment of FIG. 3.

 The internal part of the intermediate upright 73, that is to say the section 75 ′, makes it possible to produce, with the external section 74, a groove 92 with a U-shaped section acting as a rebate in which the fixed glazing 71 is inserted.

 The internal profile 75 ', of tubular shape, has a rectangular section which extends, on the side of the fixed glazing 71, substantially up to the level of the end of the sidewall or rim 77 of the external profile 74. This profile 75' and the flank 77 materialize the sides of the groove 92.

 A seal 93 is interposed between the profile 75 'and the glazing. This seal is positioned after the glazing 71 has been placed in the groove 92.

 The fixed glazing 71 is also fixed, as shown in FIG. 3, on its three other sides, by means of glazing beads 83 which are fixed on the frame and in particular on the groove 80 of the profile 5 of said frame.

 The internal profile 75 'also has, on the side of the opening, a groove 80 which corresponds to the groove provided on the frame and in particular on the profile 5 of the latter.

 FIG. 6 represents an alternative embodiment of FIG. 5 which corresponds to the embodiment of FIG. 4.

 The internal profile 85 ′ of the intermediate upright 73 ′, made of a thermoplastic material of the PVC or other type, forms, with the flank or rim 77 of the external profile 84, a groove 92 with a U section, forming a rebate in which the glazing is inserted. fixed 71. Likewise, a seal 93 ′ is interposed between the profile 85 ′ and the internal face of the fixed glazing 71.

 The profile 85 ′, has an L-shape, tubular, and its branch which is substantially parallel to the glazing 71, extends practically to the same level as the end of the flank or rim 77 of the profile 84. The other branch L is fixed to the profile 84 by all appropriate means.

 On the side of the opening, the profile 85 ′ has a groove 86 which corresponds to the groove 86 provided on the frame 1 and in particular on the internal wall 45.

 The junction system 6 that is encountered in the frame 1, in the counterbone 8, and in the intermediate upright 73 is shown in FIG. 7 on a large scale. This joining system can be used for all types of chassis, that is to say even for chassis made entirely of aluminum.

 It consists of a profile obtained by extrusion, formed of two bars 61, 62 made for example of thermoplastic material of the PVC type. These bars 61 and 62 are interconnected by a wall 63 arranged in the middle part for example. This wall 63 constitutes a sort of screen which reinforces the insulation between the profiles to be assembled.

 The bar 62 that is to say the bar which is normally visible when the chassis is installed, is masked by a veil 64 whose section is similar for example to a trapezoid. This veil makes it possible to close the cavity which remains between the sections 4 and 5 of the frame 1, for example, as shown in FIG. 11. This veil 64 also has the effect of protecting the bar 62 against damage and "or attacks of all kinds This veil 64 can be extruded at the same time as the bars 61, 62 and, at the outlet of the die, receive a coating which allows, for example, to adapt its color to that of the aluminum profiles.

 This veil 64 can also be produced at the same time as the bars 61, 62 by a coextrusion technique. In this case, the veil 64 can be produced with a material whose color is different from that of the bars to correspond to that of the aluminum profiles to be assembled.

 Each bar 61, 62 is rectilinear and comprises at each of its ends, tenons 65 in the form of a dovetail. These studs cooperate, as shown in FIG. 9, with grooves 66 arranged in particular on the aluminum profile or profiles of the frame 1, of the counter-link 8, of the intermediate upright 73 ...

 The geometry and quality of the assembly between the aluminum profile and the bars, as well as the correct positioning of one with respect to the other, depend above all on the geometry of the bars.

 The geometry of the aluminum profile is more regular and rigorous than that of the bars made of thermoplastic material. Also, to achieve a high degree of precision in the assembly, it is preferable to carry out before this assembly, a calibration and machining operation of the bars, and at least of the pins 65. This operation can be carried out at the exit from the die and from the shaping of these profiles.

 FIG. 8 represents the machining of the profile by means of a pair of milling cutter trains 67. This machining operation in fact concerns the pins 65 situated at the ends of the bars 61 and 62.

 The milling cutter trains 67 make it possible to establish precise ribs for the tenons 65, their spacing, and the parallelism of their end faces 68.

 Each set of cutters consists of stacked disc cutters comprising three large diameter cutters to calibrate the width A of the studs, and two cutters of slightly smaller diameter interposed between the others to straighten the ends of said studs 65, in order to obtain a dimension D precise.

 The calibration operation also makes it possible to establish the same distance B between the studs on each side, by putting them at the same dimension A, that is to say at the same thickness. The end faces 68 of the studs are erected simultaneously so as to be merged in the same plane on one side, and on the other the two planes being parallel to each other, separated by a distance D.

 Before the crimping operation, the pins 65 are introduced into the grooves 66 of the aluminum profile by threading from one of the ends of said profile. To facilitate this threading, it is important to have profiles with perfect geometry, whose ribs correspond to those of aluminum profiles. The ribs of the latter being slightly greater than those of the profiles.

 It is therefore necessary that the dimension B between the pins 65 located on the same side may vary slightly at the time of crimping. This rib B is initially slightly higher than the rib after crimping.

 In addition to crimping, the bars can be glued in the grooves 66. The adhesive is, for example, introduced into the grooves 66, before the tenons 65 are threaded.

 The actual crimping operation, FIG. 10, consists in closing the flanges 69 arranged outside the grooves 66. This crimping operation is carried out on an appropriate machine.

 Figure 12 shows the assembly of an aluminum profile 4 'constituting the outer wall of the frame and a profile 45 constituting the inner wall, made of thermoplastic material of the PVC type. The PVC profile comprises, to allow assembly according to a mode identical to that of the assembly used for the junction system 6, a pair of pins 65 which can be erected and calibrated by means of a train of suitable cutters, as previously described.

 FIG. 13 represents an alternative embodiment in which, for example, the section 45 made of thermoplastic material of the PVC or other type, comprises a single stud 65 ′, of large width which is inserted into an appropriate groove arranged in the aluminum section 4 ′ constituting the outer wall of the frame 1. This assembly is suitable in the same way for the profiles of the buttress 8 or for the production of the intermediate upright 73 '.

 FIG. 14 represents the assembly of an aluminum profile 4 ′ and a PVC profile 45, the assembly constituting a profile for the production of the frame 1.

 FIG. 15 represents a window door frame with two openings 2 and 3 and a fixed part 94.

 Note the external profile 4, 4 'of the frame 1, made of aluminum according to the embodiment of Figures 1 or 2. We also note the counter-beat 8 and the fixed intermediate amount 73, 73'.

 This chassis comprises at the lower part of the openings 2 and 3 and of the fixed part 94, filling panels 95, made of suitable material of the composite material type. These panels are separated from the glazing of each of the openings and from the glazing of the fixed part, by means of a horizontal cross member 96. This horizontal cross member 96 is shown in section in FIG. 16. It is constituted, for the external facade, of at least one section 97 made of aluminum and, for the internal face, of a section 99 made of thermoplastic material of the PVC type.

 The profile 99 has a T-shaped section so as to form two rebates: a rebate 101 for the lower part of the glazing and a rebate 102 to receive the upper part of the panel 95.

 The section 97 also has a T-shaped section for example, and it fits into a groove 103 provided in the section 99 with locking by clipping or the like.

 This arrangement makes it possible to maintain homogeneity between the materials used outside which are exclusively made of aluminum and the materials used inside which are, depending on the case, aluminum or thermoplastic material for the most part.

 FIG. 15 also shows, as a variant, a French window which comprises a lock 104. The size of this lock 104 is such that it is necessary to add to the central upright of the opening which normally comprises the system of closure, an additional amount 105 which provides sufficient thickness to accommodate said lock.

FIG. 17 shows, in section at the stand 106, the installation of the complementary upright 105 on the internal part of the primary central upright of the frame 9 of the opening 2
The upright 105 consists of a tubular section 107 made of thermoplastic material of the PVC or other type, preferably identical to the material used for the production of the frames of the opening elements.

 This profile 107 has a flat face 108 which bears on the internal face 109 of the central upright of the frame 9 of the opening 2. A tab 110, projecting from the face 108 of the profile 107 makes it possible to position and wedge the latter by relative to the side wall of the rebate 12 arranged in the central frame of the frame 9. The assembly of the upright 105 on the central upright of the opening is carried out by any appropriate means, screwing, gluing, riveting ...

 The amount 105 has a rebate 111 which accommodates the glazing 11 '. This upright 105 has an L-shaped section formed by several tubular beams of square and / or rectangular section. The angle of the upright 105, the section of which is square, allows the housing of the lock 104. It comprises, in a contiguous manner, tubular parts of rectangular section forming the sides of the rebate 111.

 The external part of the upright 105 consists of a profile 112 made of aluminum, the cross section of which is U-shaped for fitting onto the profile 107.

 It is fixed by any appropriate means to this thermoplastic profile 107. This profile 112 has a lip 116 which extends in the rebate 12 of the central upright of the frame 9 so as to be in contact with the glazing seal 15 which is arranged directly on the glazing bead 13. The seal 15 is also in contact, as the case may be, with the counterbutt 8 or, if the opening is single, with the frame 1 and in particular its profile 4, or also with the external profile of the intermediate upright 73 , 73 '.

The profile 112 has an external groove 113 which accommodates a glazing bead 114 made of aluminum, which glazing bead 114 with cross section
L, is clipped into said groove 113 of the profile 112 to hold the glazing 11 'by means of a seal 115.

 Note, Figure 17, part of the closing mechanism 117 housed in the groove 22 of the amount of the door. This mechanism allows the opening of the doors and it is possibly associated with the lock 104 housed in the thickness of the uprights 9 and 105.

 Figures 18 to 20 show chassis equipped with ventilation associated for example with an installation of the VMC (mechanical controlled ventilation) type.

 Figures 18 and 19, this ventilation is arranged at the upper cross member of the frame. It is in fact arranged in a complementary cross member 120 which is fixed to the upper cross member of the frame 1.

 In the case of Figure 18, the complementary cross member 120 consists of an outer wall formed of an aluminum profile 124 and an inner wall formed of a tubular profile 125 also of aluminum. The two sections 124 and 125 are assembled by means of a junction system 6 'which forms a thermal break, consisting for example of two strips of thermoplastic material of the PVC or other type.

 The profile 124 forms a sort of doubling of the profile 4 constituting the external wall of the frame 1. It is separated from the profile 4 so as to allow air circulation in the space left between the two.

 Profile 125 has orifices 126 allowing the passage of air, which passage is completed by means of one or more vents 127 positioned on the internal face of said profile 125. These air intake vents optionally respect an acoustic weakening ; they can also possibly be self-adjusting, associated or not with a CMV.

 The profile 125 is fixed by any appropriate means, to the upright I and in particular to the profile 5 constituting the internal wall, at the level of the groove 80 which corresponds to the receiving groove for the glazing beads 83 as shown in FIG. 3.
