Each section comprises a groove (18) provided with sealing (22) for receiving the glazing. An Independent claim is included for a method of manufacture and assembly of the window.

Description

Thermoplastic material swing, assembly procedure of said swing and opening of two Hinged like a window.

The invention relates to windows, windows, doors, or similar elements, of thermoplastic material.

It deals more particularly with a swing than belongs to the openings of this type, of a procedure of assembly of such a swing, as well as an opening of this type which has two hinges intended to support the one in the other.

Material leaflets are already known thermoplastic, such as PVC especially, intended for windows, door-windows, doors or elements analogues

Reference is made to Figure 1, which represents a horizontal section view of the central part of a window with two sheets of the prior art.

The hinges 100 of this type are intended to lean on another swing 101, or a sleeper, and include a panel 102, especially a sheet of glass, carried by a frame and within it.

The frame also includes two uprights 103 and two crossbars associated perpendicularly two to two towards their ends, being attached a stud and a crossbar to each other according to a plane that forms an angle close to 45º with said upright and said crossbar, passing said plane substantially through A corner of the frame.

In the prior art, the assembly of the Swing 100 is performed as follows:

-

in a first time, the crossbars are associated two to two in order to form a frame, this assembly being made by welding, due to the thermoplastic properties of the constituent material of the uprights and crossbars;

-

in a second time, panel 102, especially the glass sheet, is placed in the frame, against supporting surfaces 104 arranged in the uprights and crossbars;

-

finally, some are associated with the framework moldings 105 in each upright and each crossbar, in order to form, with  the aforementioned support surfaces, a throat 106 which allows to block, the panel in the frame.

In addition, gaskets 107, 108, placed on the one hand on the support surfaces 104 arranged in the uprights and crossbars, and on the other hand, on moldings 105, ensure a good tightness between the frame and the panel 102.

The existence of moldings 105 thus responds to a double objective, secure the panel block 102 within the framework of the swing 100, and participate in the tightness between the frame and the panel 102.

In this assembly method, moldings 105 They are therefore indispensable. Therefore, a swing according to The prior art comprises at least two profiles, at least one P1 profile constituting the uprights and crossbars, and a profile P2 in which moldings 105 are trimmed.

On the other hand, an opening 109 according to the prior art that includes two hinges 100, 101, as illustrated in figure 1, generally comprises more profiles, being different the profiles used for the realization of the two swinging

Thus, the realization of an opening, especially from a prior art window, it needs several  profiles, for example, four profiles in the case of realization of Figure 1 (P1, P2, P3, P4).

However, the cost of tooling and machines in extrusion rows is extremely high. In addition, the greater the number of profiles to be manufactured, the shorter the extrusion campaigns, and therefore more
expensive.

The invention aims to solve these problems, especially providing a swing of material thermoplastic as well as an opening that has two hinges, which does not It includes more than a single profile.

As just explained, the realization of a opening of this type with a single profile needs in combination:

-

not there is a need for moldings, therefore the tightness between the panel and the frame so different;

       \ newpage
    

-

that he assembly is not done by welding since this must be done imperatively before placement of the panel, which induces the presence of moldings. The invention thus provides another assembly method

According to a first aspect, the invention relates to to a swing of the type described above, whose amounts and crossbars are each constituted by a single and same profile hollow thermoplastic material. The uprights are associated transversely two to two towards its ends, being assembled an upright and crossbar adjacent to each other according to a plane that passes sensibly through a corner of the frame and forms a angle, especially close to 45 °, with said amount and said crossbar.

The profile presents on one of its sides a throat that receives an edge of the panel, and on the opposite side, a protruding part that extends substantially parallel to the median plane of said throat and out of phase with respect to said medium plane, bearing the protruding part, with respect to said medium plane, a seal designed to cooperate with a support surface made on another swing or in a sleeping.

According to the invention, the throat includes some sealing means that cooperate with the edge of the embedded panel in that throat, so that the uprights and crossbars of the swing are devoid of moldings to perform the tightness with said panel.

In addition, the assembly between an upright and a adjacent crossbar is performed with the help of a rigid organ in square shape whose branches fit the one in the stile and the another on the crossbar.

The throat sealing means they comprise two lips each located towards the extreme part of a side wall of the throat and directed inwards from said throat, said manufacturing lips having come with the profile.

The squad includes an outstanding part linear that forms an angle close to 45º with each of its branches, said outstanding part being destined, once they have been assembled an adjacent upright and crossbar by said squad, to fill the game between said amount and said crossbar, especially for sealing purposes.

According to other characteristics, the profiles are fixed to each other by some screws that pass through of holes in the corresponding square.

The screws act by themselves as a tap and the profile comprises alveoli that extend along the axis of the profile and of substantially triangular straight section, receiving the alveoli said screws, the dimensions of the section being of the alveoli slightly smaller than the diameter of the screws, so that, during the assembly of the swing, you can perform at the same time screwing on the wall of the alveoli and their guided by these alveoli.

The square comprises at least one flat wall which extends approximately perpendicular to one of its branches, sensibly from the common extreme part of the two branches, and in a direction opposite to the other branch, being destined said flat wall to seal at least one cavity of an upright or of a crossbar, towards the end of the constitutive profile of said amount or said crossbar.

Each branch of the squad comprises a plurality of wings that fit into cavities of an upright or  a crossbar, towards the end of the constitutive profile of said amount or said crossbar.

According to a second aspect, the invention is refers to a manufacturing and assembly procedure of a swing as just described.

The manufacturing and assembly procedure It comprises the following stages:

to)

be cut the uprights and the crossbars in a hollow profile according to planes that form an angle close to 45º with the axis of said profile;

b)

C)

be fit the panel into the throats of the uprights, or respectively of the crossbars;

d)

be fit the free branches of the squares linked to the crossbars, or respectively to the uprights, in the extreme parts of the uprights, or respectively of the crossbars, that carry the panel, so that the frame is closed.

According to a possible embodiment, some means of maintaining the branches of the squads in the crossbars, or respectively in the uprights, such as especially the gluing or click fixing system.

After step d), each amount is fixed to the adjacent crossbar by some screws that pass through some holes of the square embedded in said upright and said crossbar.

Finally, according to a third aspect, the invention refers to an opening, such as especially a window, door-window, door, or element analog, which comprises a first and a second leaflet such as described above, said leaflets being intended for lean on each other, the first swing being constituted for a first profile and the second swing for a second profile.

According to the invention, the first and second profiles are identical, and the profile that constitutes the amount inside of the second swing is placed in such a way that confuse, when the opening is closed, with the image of the profile that constitutes the inside post of the first swing by a 180º rotation with respect to an axis located, with with respect to said first swing, substantially in the medium plane of the throat, approximately parallel to the interior stile, of the side of the protruding part, at a distance from the bottom of the throat, outside the profile.

According to one embodiment, the profile comprises also an extension that extends substantially parallel to the median plane of the throat, said location being extension of the same side of the profile as the protruding part, and being out of phase with respect to said median plane in the semiplane that does not contain said outstanding part, being a face of the extension substantially parallel to the median plane but  not facing said median plane, so that said face of the constitutive profile of the inside post of the first swing forms a support surface that cooperates with the board of tightness of the protruding part of the constitutive profile of the interior amount of the second swing.

Reference is made first to Figure 2 which represents a window 1 comprising a sleeping frame 2, fixed to the masonry, and two hinges 3, 4 that open towards the interior I of the building that receives the window. Good understood, the invention also relates to the case of a window that opens outwards E of the construction.

Hinges 3, 4 are carried by the sleeper 2 by means of hardware pieces such as hinges and hinges, not represented.

The first sheet 3, named below "swing", carries other pieces of hardware, such as a grip, etc. It is the double swing, that is, the blade, what is Open first to open the window.

The second sheet 4, named as soon as the "semi-fixed swing" is the leaf that opens last when the window is opened.

Throughout the description, it is designated by "swing" at the same time in general each of the two sheets 3, 4, and particularly the swing 3.

Each swing 3, 4 comprises a frame and, cover in the frame and by the latter, a sheet of glass 5. According to a embodiment, illustrated especially in Figure 3, the sheet of glass 5 is a double insulating glass comprising an element of inner glass 6, an outer glass element 7, a space 8 which separates the two glass elements, and a peripheral brace 9. The glass sheet 5 defines a medium plane P.

In the continuation of the description, and for For greater comfort, window 1 is considered closed. He plane P is then that one, in which is the frame of each one of the hinges 3, 4 and the sleeper 2, or the one in whose neighborhood is located.

The frame of the swing 3 comprises:

-

two vertical uprights: an outer upright 10, articulated to the sleeper 2, and an inner stud 11 intended to rest on the semi-fixed swing 4;

-

a upper crossbar 12 and an inner crossbar 13.

Similarly, the swing frame Semi-fixed 4 comprises an outer stud 14, articulated to the sleeper 2, and an inner stud 15, intended to rest on the swing 3, as well as an upper crossbar 16 and a crossbar bottom 17.

In a first time, the swing 3 is described as well as its assembly procedure.

Uprights 10, 11 and crossbars 12, 13 they are constituted by a single and same hollow profile, made of thermoplastic material, such as PVC, obtained, for example, by extrusion.

The profile, especially represented in the Figures 3 and 4, initially includes, on one of its sides, a throat 18 noticeably parallelepiped that extends following The axis of the profile. The throat 18 comprises a bottom 19 substantially flat and two side walls 20, 21, substantially perpendicular to the bottom 19. The throat 18 is intended for receive the edge of the glass sheet 5, then confusing substantially the median plane of the throat 18 perpendicular to the bottom 19 with the median plane 15 of the glass sheet 5. A then, the median plane will also be designated "P" of throat 18 of the profile.

The extreme parts 20a, 21a of the walls laterals 20, 21 each include a sealing lip extruded together with the profile, which extends substantially parallel to the axis of the profile. The lips of tightness 22 are directed towards the inside of the throat 18 and are flexible enough to be deformed at proceed to insert the glass sheet 5 into said throat 18. As illustrated in Figure 3, once the glass sheet 5 it is placed in its place in throat 18, each lip 22 is supported in the corresponding glass element 6, 7, and is slightly curved, directing the concavity of lip 22 towards the inside of the throat 18.

The sealing lips 22 are made in a PVC more flexible than the PVC used for the rest of the profile. They can thus ensure a perfect seal, which prevents notably the penetration of water by capillarity inside of the throat 18.

The profile also includes, on its opposite side next to the throat 18, an outstanding part 23 that extends substantially parallel to the median plane P of throat 18, and a certain distance is offset with respect to to said medium plane P.

The projecting part 23 comprises a wall exterior 24 substantially parallel to the median plane P, a wall interior 25, substantially parallel to the exterior wall 24, a link wall 26 and an extreme wall 27, the latter being substantially perpendicular to the outer and inner walls 24 25. These four walls 24, 25, 26, 27 are noticeably flat, including the outer wall 24 furthermore a step 28 towards the inside the profile.

In addition, the projecting part 23 includes a internal cavity 29 defined between the four walls 24, 25, 26, 27. The inner face 25 has a linear cavity 3 'which is extends substantially parallel to the axis of the profile, and intended to receive a seal 31.

On the other hand, the profile includes an alveolus 32 of triangular straight section, which extends substantially from parallel to the axis of the profile, said socket being located in the inside of the profile, between the protruding part 23 and the throat 18. As will be described later, socket 32 is intended to receive some screws during the assembly of the swing 3.

The projecting part 23 is attached to the part end 21a of the side wall 21 of the throat 18 by a wall curve 33, whose concavity is directed towards the interior of the profile. A cavity 34 is defined between the curved wall 33, the wall of link 26 of the projecting part 23, the side wall 21 of the throat 18 and socket 32.

The profile also includes a 32 'socket, a cavity 34 'and a curved wall 33' symmetrical of the alveoli 32, cavity 34 and curved wall 33 with respect to the median plane P of the throat 18.

Finally, the profile includes a cavity 35 in U-shaped whose bottom 36 is parallel and adjacent to bottom 19 of the throat 18, said cavity 35 being symmetrical with respect to the medium plane P. The alveoli 32, 32 'are located to one another part of the bottom 36 of said cavity in U 35.

       \ newpage
    

A first branch 37 of the U-35 cavity is adjacent to the protruding part 23, while a second branch forms an extension 38 of the profile, extension 38 is therefore extends substantially parallel to the plane medium P and is located on the same side of the profile as the part outstanding 23. Extension 38 is out of date with respect to medium plane P in the semiplane that does not contain the part protruding 23. The extension 38 comprises a face 39 noticeably flat and directed outward from the profile that form a support surface, as will be described later.

Between the branches 37, 38 of a cavity in U 35, and outside the profile, there is a space 40, while inside the cavity in U 35 a piece 41 is present intended to stiffen the profile.

As depicted in Figures 4 and 5, the uprights 10, 11 and the crossbars 12, 13 of the swing 3 are parts of the profile just described, having made the cuts along a 45 ° inclined plane with respect to the axis of said profile.

For each of the uprights 10, 11 and each of the crossbars 12, 13, the projecting part 23 of the profile is located on the same side of the frame, in this case inward I of the construction that window 1 receives.

Uprights 10, 11 and crossbars 12, 13 they are associated perpendicularly two to two towards their ends, of way they form the frame of the swing 3. An upright and a adjacent crossbars are assembled to each other according to a plane that it forms an angle close to 45º, with said amount and said crossbar, and going through a corner 42 of the framework.

The assembly is not done by welding, as it is the case in the prior art, but mechanically, with the help of four rigid schemes 43.

Square 43, as depicted in Figures 4 to 7, includes two branches 44, 45 that form a angle close to 90º. Each branch includes a plurality of wings, respectively 44a, 45a, linear straight section or U especially.

Each of these wings 44a, 45a is intended for be fitted, during assembly of uprights 10, 11 and of the crossbars 12, 13, especially in the cavities 29, 34, 34 ', 35 of the constitutive profile of the stud or crossbar corresponding, as shown in figure 7 representing a cutting of a profile constituting a stud or a crossbar, towards the end of said stile or said crossbar, having a branch of square 43 was fitted in said profile.

Thus, the assembly of an upright 10 with a adjacent crossbar 12 is made with the help of a square 43 whose branches 44, 45 are embedded the one in the pillar 10 and the another on the crossbar 12.

Square 43 also includes a wall substantially flat 46 that forms an angle close to 45º with each of the branches 44, 45 of the square 43 and passing to the common extreme part of the two branches 44, 45.

The wall 46 is intended to contact with the ends at 45º of the uprights and crossbars of the swing 3. In addition, an edge 47 of the wall 46 forms an protruding part Linear intended, once the stud 10 and the adjacent crossbar 12 have been assembled by squad 43, to fill the game J between said upright 10 and said crossbar 12, for the purpose of tightness and aesthetics among others (see figure 5).

The following describes the procedure of swing assembly 3.

At first, a branch 44 of a square 43 in each of the end portions of the crossbar upper 12. Proceed analogously with the lower crossbar 13.

Preferably, the squares 43 are maintained on the crossbars 12, 13, for example by gluing, with the help of some fixing means by click, or with mastics.

In a second time, the sheet of glass 5 in the throat 18 of the constituent profiles of the uprights 10, 11.

Then, the set of uprights 10, 11 - glass element 5 and the crossbar assembly 12, 13- four squads 43, are associated so that they form the framework of the swing 3, fitting the branches 45 of the squares 43 until then not embedded in profiles currently in the extreme parts of the amounts 10, 11.

Finally, the squares 43 are fixed to the uprights 10, 11 and crossbars 12, 13 by screwing. To this In effect, the brackets 43 include holes 48 (see figure 6) intended for the passage of fixing screws 49.

As Figures 5 and 7 show, the holes 48 are positioned such that when branch 44 of the square 43 fits into the crossbar's constituent profile upper 12, and the branch 45 of the square 43 fits into the profile constituting the lower upright 11, the holes 48 of the branch 44 are aligned with the alveoli 32, 32 'of the constitutive profile of the interior stud 11.

In addition, the dimensions of the straight section of the alveoli 32, 32 'of the profile are slightly lower than diameter of the fixing screws 49, said screws acting fixing 49 as dies by themselves. So screw 49 passes through hole 48 of square 43, and then cooperates with the socket 32, for example, screwing in the wall of socket 32 and being guided by said socket 32.

Well understood, you can also use a assembly procedure similar to the one just described which associates the glass sheet 5 to the crossbars 12, 13 and the brackets 43 to the studs 10, 11.

Figure 5 schematically represents the frame of swing 3 once assembled as well as the position of the brackets 43 and fixing screws 49 and the section down of the constitutive profiles of the amounts 10, 11 and crossbars 12, 13.

The mechanical assembly procedure according to the invention has the advantage, with respect to the prior art, of not needing moldings, being secured to tightness between the glass sheet 5 and frame 3 and glass sheet assembly 5 in the throat 18 of the profile by the lip 22. On the contrary, the prior art necessarily involves the placement of the sheet glass 5 after assembly by welding the frame, and by both the further addition of moldings.

The semi-fixed swing is described below. 4 and window 1.

The uprights 14, 15 and the crossbars 16, 17 of the semi-fixed swing 4 are constituted by the same hollow profile than the uprights 10, 11 and the crossbars 12, 13 of the swing 3.

As depicted in figures 8 and 9, the uprights 14, 15 and the crossbars 16, 17 of the semi-fixed swing 4 are portions of the profile just described, having made the cuts according to a 45º inclined plane with respect to the axis of said profile.

For each of the crossbars 16, 17, as well as for the outer post 14, the projecting part 23 of the profile it is located on the same side of the frame, in this case inwards I of the construction that receives window 1, while for the lower upright 15, the projecting part 23 of the profile is located on the opposite side of the frame, in this case outwards E of the construction that receives window 1. This feature It is remarkably illustrated in Figure 9, where you can see thanks to the representation of the dejected sections of the profiles that the inner stud 15 of the semi-fixed swing 4 is inverted in relation to the crossbars 16, 17 and the amount exterior 14.

Thus, as illustrated in Figure 3, the amount inside 11 of the swing 3 and the inner amount 15 of the swing Semifix 4 are symmetrical, when window1 is closed, with with respect to an X axis such that:

-

the axis X is located, when the window is closed, substantially in the median plane P of throat 18;

-

the axis X is substantially parallel to the window studs one;

-

the axis X is located on the side of the projecting part 23 of the upright interior 11 of the swing 3;

-

the axis X is located at a distance from the bottom 19 of the throat 18 of the interior post 11 of the swing 3, outside the profile, in space 40.

When window 1 is closed, the face exterior 39 of extension 38 of the interior pillar 11 of the swing 3 forms a support surface for the gasket tightness 31 placed in the linear cavity 30 of the upright interior 15 of the semi-fixed swing 4. Reciprocally, the face exterior 39 of extension 38 of the interior amount 15 of the semi-fixed swing 4 forms a support surface for the gasket tightness 31 placed in the linear cavity 30 of the upright interior 11 of the swing 3.

This double swing window structure 1 using a reversible profile allows you to reduce the number of profiles used for the manufacture of said window 1, and by consequently reduce costs considerably.

As in case of swing 3, the uprights 14, 15 and crossbars 16, 17 are perpendicularly associated two by two towards its ends, according to a 45º inclined plane that passes through a corner 42 of the frame, so that they form the frame of the semi-fixed swing 4.

The assembly is done mechanically with help of rigid squads.

The assembly of the outer stud 14 to the crossbars 16, 17 is made with the help of two identical 43 squares  to those used for swing assembly 3.

On the contrary, the fact that the amount inside 15 of the semi-fixed leaf 4 is inverted with respect to the crossbars 16, 17 need a supplementary operation of machining for the assembly of the semi-fixed frame and the use of another type of square, called "semi-angle angle square" fifty.

The extreme part of the crossbars 16, 17 intended to be assembled to the interior post 15 of the swing semi-fixed 4, as well as the end parts of said inner stud 15 are machined, as shown in Figures 8 and 9, to in order to allow the assembly of these different elements of the semi-fixed swing 4.

This machining induces the appearance of cavities at the ends of the corresponding profiles, cavities placed differently from those that appear during a simple cut at 45º, and therefore cannot be sealed by the 43rd squad during assembly.

The invention therefore provides a square of half-angle 50, illustrated in Figure 10.

The semi-fixed angle square 50 comprises two branches 51, 52, including a plurality of wings 51a, 52a each intended to be embedded in the cavities of the constitutive profile of a crossbar 16, 17 or of the inner pillar 15 of the swing semifix 4.

The semi-fixed angle square 50 comprises furthermore a substantially flat wall 53 forming a close angle at 45º with each of the branches 51, 52 of said square 50, and which passes into the common extreme part of the two branches 51, 52. As in the case of swing 3, this wall 53 allows to fill the game existing between the pillar 15 and the crossbars 16, 17 in the mounting.

Finally, the semi-fixed angle square it comprises two substantially flat walls 54, 55 that extend from the common extreme part of the two branches 51, 52, each parallel to one of the branches 51, 52 and in opposition to said branch 51, 52. Walls 54, 55 are intended to seal the Profile cavities appeared following machining before aforementioned.

The swing assembly procedure semifix 4 is similar to that of swing 3, except for the replacement of "normal" brackets 43 by a semi-fixed angle brackets 50 on the end parts of the inner stud 15 of the swing semifix 4.

Figure 9 schematically represents the frame of semi-fixed swing 4 once assembled, as well as the position of the brackets 43, 50 and of the fixing screws 48 and the section depleted of the constitutive profiles of the uprights 14, 15 and of the crossbars 16, 17.

The invention that has just been described in the particular case of a window can be applied, well understood, to other types of openings, such as especially a door-window, in which the profile used is similar, however, the most prominent part in the side of the profile, or a door, the panel can be inserted in the throat of the profile, for example, a solid panel and not a glass element.

On the other hand, the specialist in the trade will understand that in the case where you want to obtain a centering of the opening handle, it may be necessary to add to the swing 3 an element consisting of another type of profile. This Supplementary profile is only optional, and the structure even of the opening is still made as for itself from A single profile

Finally, although the invention has been described in the case of a particular embodiment of a rectangular leaflet,  it can also be applied to other forms of hinges, in particular of the trapezoidal hinges. In the latter case, the angles between the uprights and crossbars, and therefore the angles of the squares used, are different from 45º, but the principle Assembly remains the same.
