Description

FIELD OF THE INVENTION

The present invention relates to a carpentry profile for a leaf opening and to a carpentry comprising such a profile. It finds at least one particularly advantageous application in the field of windows with hidden opening, comprising a joinery preferably formed at least in part from aluminum.

TECHNOLOGICAL BACKGROUND

In the field of casement windows, also known as a striking window, the window or opening frame, that is to say the movable part of the joinery, is rotatably mounted on the window frame or window frame.

The use of aluminum joinery makes it possible to design light, solid and aesthetic structures.

In order to reduce the costs associated with the manufacture of an all-aluminum joinery, a particularly advantageous possibility consists in integrating a cheaper core, for example in PVC, within the aluminum joinery.

The core is intended to support glazing. It is made up of several profiles generally assembled with miter cuts by means of brackets.

After assembly of the core sections so as to form a frame, the glazing is positioned in the frame.

The glazing is finally held in the frame by a shuttering. This glazing allows in particular to secure the glazing and the frame, and to ensure the tightness of the assembly. The glazing block is made up of several glazing beads generally cut to miter cut.

For a given frame size, the glazed surface of the glazing can be optimized by at least partially superimposing the opening and frame frames. In particular, the sleeping frame is configured to hide most of the opening frame for an observer located on the outside of the window. Such a carpentry configuration is referred to as a hidden sash carpentry.

Figure 1 shows in cross section an example of carpentry with hidden opening. The opening 1 comprises a PVC core 10 supporting a glazing 2 held integrally with the core 10 by a glazing bead 3. The core 10 and the glazing bead 3 are arranged with the structural profile 4 so as to be mainly masked by the flap 50 of the frame 5 for an observer located outside.

A disadvantage of such a solution is that it requires numerous assembly steps. The costs and production times of such carpentry can therefore be high.

In addition, the finish quality of miter cut corners may be insufficient. An object of the present invention is to at least partially overcome the drawbacks mentioned above.

More particularly, the invention aims to propose a hidden opening core profile making it possible to reduce the costs and / or the production times of a joinery.

The invention also aims to provide a hidden opening core profile making it possible to improve the quality of finish of miter cut angles.

Another object of the present invention relates to a method of mounting a carpentry.

SUMMARY OF THE INVENTION

A first aspect of the invention relates to a hinged carpentry with hidden sash, comprising a frame, a hidden sash sash forming a frame intended to accommodate glazing, the hidden sash comprising a plurality of sash core profiles. Each opening core profile comprises a core and a glazing bead together defining a space intended to accommodate part of the glazing.

Advantageously, the core profile also includes an articulation connecting the glazing bead to the core integrally. This articulation is advantageously configured to allow mobility of the glazing bead in rotation relative to the core, at least between an open position and a closed position, preferably in which the glazing bead is configured to partially maintain at least the glazing.

The joinery is configured so that when the concealed leaf opening is pressed against the frame, that is to say in the closed position, the frame or a beat of the frame masks the whole glazing bead or mask at least partially, and preferably mainly, the glazing beads so as to reveal only a glazing strip width less than or equal to 2 cm (centimeters, 10 ' ² meters) and preferably less than or equal to 1 cm. According to an alternative embodiment or combined with the previous one, the glazing bead preferably comprises a seal configured to seal the glazing. The joinery is configured in such a way that in the closed position, a beat of the frame extends, in a direction parallel to the main plane in which the glazing extends, up to the seal.

Another aspect of the invention relates to a sash core profile configured to be integrated into a casement sash of a carpentry, preferably a concealed sash sash of a carpentry.

Advantageously but not limited to, this profile comprises a glazing bead and an articulation, said articulation integrally connecting the glazing bead to the profile and being configured to allow mobility of the glazing bead in rotation relative to the profile, at least between an open position and a position closed.

Thus, the invention provides a profile with a foldable integrated glazing bead in the closed position. The assembly times of the glazing bead are thus significantly reduced since the glazing bead is directly attached to the profile. The positioning of the glazing can be done in the open position of the glazing bead, and the maintenance of the glazing is done simply and quickly by tilting the glazing bead in the closed position. The production times of a carpentry comprising such a profile are therefore advantageously reduced.

Furthermore, in the closed position, the profile and the glazing bead can advantageously be cut simultaneously so as to form miter-cut angles.

This makes it possible to reduce the number of cutting-off steps compared with a conventional production process of a joinery comprising at least one cutting-off step of the glazing bead independent of another cutting-off step of the profile. The profile according to the invention therefore makes it possible to reduce the costs and the production times of a joinery, in particular of an aluminum joinery.

This also makes it possible to guarantee substantially identical cutting conditions for the profile and the glazing bead, which ultimately improves the quality of finish of the cutting angles of the profile.

According to an advantageous possibility, the profile is made of PVC and the joint and the glazing bead are coextruded with the profile.

This makes it possible to produce a glazing bead and a joint directly attached to the profile. The connection between the glazing bead and the joint on the one hand, and the connection between the joint and the profile on the other hand can thus be optimized.

This also makes it possible to reduce the cost and / or the time of production of the glazing bead and of the profile. Simultaneous production of a glazing bead and a profile independent of each other requires two separate production lines, which increases the cost. A production on the same production line of a glazing bead and a profile independent of each other implies an alternative production of one and the other, which increases the time.

A profile according to the invention coextruded with the joint and the glazing bead is therefore particularly advantageous for the production of aluminum joinery comprising a PVC core.

A second aspect of the invention relates to an aluminum joinery comprising a glazing and a hidden sash frame formed by a plurality of sash core profiles according to the first aspect of the invention, each of said plurality of profiles being assembled with at least one structural profile, preferably made of aluminum.

A third aspect of the invention relates to a process for producing a joinery according to the first aspect of the invention, comprising at least the following steps:

Provide at least one opening core profile according to the second aspect of the invention,

- Assemble the at least one opening core profile with at least one structural profile, preferably in aluminum,

- Cut the assembled profiles, the glazing bead being in the closed position, so as to obtain a plurality of assembled profiles,

Form a sash frame from said plurality of assembled profiles, Open the glazing bead of each of the sash core profiles of the sash frame formed,

Put the glazing in the window frame,

Fold the glazing bead of each of the sash core sections of the sash frame into the closed position.

Another aspect of the invention relates to a sash core profile configured to be integrated into a hidden leaf sash of a carpentry. The profile comprises a core configured to receive glazing, a glazing bead and a hinge, said hinge integrally connecting the glazing bead to the core and being configured to allow mobility of the glazing bead in rotation relative to the core, at least between an open position and a preferably closed position in which the glazing bead is configured to partially maintain the glazing.

In the following description and claims, by:

carpentry: a structure, such as a window or a door, comprising a frame made at least in part from parts preferably of small cross section, for example aluminum and / or PVC profiles, assembled together to support the minus glazing. The chassis comprises at least one opening chassis, and preferably a dormant chassis.

dormant: a frame or fixed frame of carpentry linked to the structural work. The frame can include, for example, metal structural profiles, polyamide thermal break profiles, a gasket in EPDM (Ethylene Propylene Diene Monomer) polymer.

opening: a frame or movable frame of the joinery linked to the frame by fittings. The opening may include core sections, structural sections, cover sections. It supports and maintains glazing also called glazed rebate.

The opening notably comprises a lower cross member, an upper cross member and lateral uprights assembled so as to form a frame. The upper and lower cross members extend horizontally, and the side uprights extend vertically.

In the case of a swing opening, the opening can also be called a swing.

hidden opening: an opening, most of which is hidden by the frame in the closed configuration, i.e. when the door is pressed against the frame.

A hidden window carpentry provides better insulation and a larger glazing area than a traditional visible window carpentry. Such joinery can advantageously be made from aluminum.

glazing: the glazing has an interior side and an exterior side. It can include single glazing, double glazing or triple glazing; the interior side, referenced int in the figures, is turned towards an interior area of a building or a room in a dwelling for example. The outer side, referenced ext in the figures, is in contact with outside air and rain in particular.

fittings: fittings depend on the type of opening. They can be hinges in the case of a swinging opening of the opening, hinges in the case of a so-called "French-style" opening, and can include locking strikes and / or rods actuating points of locking on a circumference of the sash frame. These fittings can be controlled by a handle integral with the opening.

glazing beads: glazing beads are profiles which hold glazing in an opening, mobile or fixed frame.

core profiles: the core profiles are structural profiles allowing to support, directly or indirectly, the glazing. They provide mechanical strength and rigidity of the chassis. They can be accessorized by closing accessories such as fittings or linkages for example.

In the following, the height is taken along the z axis, the length is taken along the x axis, and the width is taken along the y axis.

"Vertical" means an orientation along the z axis. "Horizontal" means an orientation along the y axis and / or along the x axis. The terms "interior", "internal" define faces or sides facing the interior of the building. The terms "exterior", "exterior" define faces or sides facing the exterior of the building. The terms "upper" and "lower" define relative positions carried by the z-axis.

A profile means a carpentry "based" on a material M, a profile, a carpentry comprising this material M only or this material M and possibly other materials. Thus, a PVC-based profile may for example be made entirely of PVC or may comprise other polymers, for example an EPDM polymer or a TPE thermoplastic elastomer (acronym for "thermoplastic elastomer"). Aluminum-based carpentry can include only aluminum-based profiles or aluminum-based profiles and PVC-based profiles.

In the following, the expressions "joinery or aluminum profile" and "joinery or aluminum profile" are used in synonyms, for the sake of brevity. Similarly, the expressions "PVC-based profile" and "PVC profile" are used in synonyms, for the sake of brevity.

We will now describe the present invention through a preferred but non-limiting embodiment.

The following description is illustrated by cross sections of the profiles of the lower cross member of the sash frame. This description applies mutatis mutandis to the profiles of the upper crossmember and the side uprights of the opening frame.

With reference to FIG. 1, a core profile 10 according to the invention comprises a structural support part 11, called a core, to which a glazing bead 3 is attached by means of a hinge 31.

This profile 10 preferably comprises a wedging part 12 configured to wedge a glazing and / or receive glazing support elements.

This profile 10 can also include an assembly part 13 configured to receive a cover profile and / or another structural profile for example.

This profile 10 also preferably comprises at least one groove 14 configured to receive accessories, such as linkage and / or closure elements for example.

This profile 10 is preferably based on PVC.

The core 11 preferably has a height dimension less than its width dimension. For example, the height of the core 11 can be between 20 mm and 50 mm and the width of the core 11 can be between 50 mm and 100 mm. According to a sectional view perpendicular to the plane yz in which the glazing 2 mainly extends, the core 11 therefore extends mainly in width and in length along a basal plane defined by the directions x and y. This reduced height dimension of the core 11 allows the profile 10 to be integrated into a hidden opening. The largest dimension of the core 11 extends in the direction x contained in the plane zx of the glazing

2.

The core 11 is preferably tubular and hollow. This helps to lighten the structure. This also makes it possible to form housings at the longitudinal ends of the core 11. These housings can in particular receive assembly brackets making it possible to assemble several profiles 10 in order to form the opening frame.

The core 11 is preferably made of PVC.

The core 11 includes an upper face 110 intended to receive the glazing directly or indirectly, a lower face 111, a first lateral face 112 called the outer face facing the outside outer side, and a second lateral face 113 called the inner side facing the side outside int.

The upper face 110 can be flat. It may alternatively include grooves and / or retaining lugs configured to maintain, directly or indirectly, the glazing.

The lower face 111 can be flat. It can alternatively include grooves and / or retaining pins configured to hold, directly or indirectly, structural elements and / or accessories.

The inner face 113 is preferably connected to the wedging part 12 and to the assembly part 13.

It also preferably forms one side of the groove 14.

The wedging part 12 preferably forms a projecting overhang from the upper face 110. It may include one or more seals 121 intended to come against the glazing.

These seals 121 may be in the form of flexible lips. In the following description, reference will be made to sealing lips as shown in the figures. However, the invention is not limiting on this type of seals and applies to any other type of seal such as tubular seals. Thus, in the examples which follow, the expression "sealing lips" or "flexible sealing lips" may be replaced by the expression "sealing joints".

The wedging part 12 may also include a groove 122 configured to partially hold and accommodate a shim or a glazing support.

It is preferably made of PVC or based on PVC. The flexible sealing lips 121, or more generally the sealing joints are preferably made of flexible PVC coextruded with the wedging part 12. Alternatively, they may be made of post-extruded EPDM or TPE. This advantageously makes it possible to replace these lips 121 if they deteriorate over time, so as to preserve a perfect seal.

The assembly part 13 preferably comprises lugs configured to cooperate by crimping with a profile, preferably made of aluminum, for example an aluminum structural profile or aluminum stiffener.

Such an aluminum structural profile makes it possible to reinforce the opening frame. It stiffens the opening comprising PVC-based profiles.

The assembly part 13 is preferably made of PVC.

It can be hollow tubular, for example reinforced by an internal central partition as illustrated in FIG. 2.

It can be filled with expanded PVC. This will provide more rigidity and resistance to the core section 10. In this case, the tubing may comprise two parts separated by the internal central partition as illustrated in FIG. 2. Alternatively, the internal central partition can be removed.

The groove 14 is preferably adjacent to the inner face 113 of the core 11. This makes it possible to limit the height under glazing of the profile 10, so as to form a hidden opening in particular.

The groove 14 is preferably made of PVC.

The outer face 112 preferably carries the hinged glazing bead 3. The articulation 31 can for example be connected to the external face 112 by a lower horizontal strip 310 projecting from said external face 112.

The junction between the lower bar 310 and the articulation 31 preferably forms a first profile in a drop of water.

The articulation 31 is preferably made of elastomer, for example EPDM or TPE, having a flexibility of between 60 and 75 Shore A. This articulation 31 is connected to the glazing bead 3, preferably at a first end of said glazing bead 3.

The junction between the glazing bead 3 and the joint 31 preferably forms a second profile in a drop of water.

The articulation 31 is configured so as to allow rotation of the glazing bead 3 between an open position and a closed position.

The open position illustrated in Figure 2 allows in particular to set up the glazing in the opening frame, or to remove it from this opening frame.

The closed position illustrated in Figure 3 keeps the glazing in place in the opening frame.

The joint 31 preferably has a thinner central region in cross section. This central region makes it possible to define a singular axis of rotation directed longitudinally and called the pivot axis, allowing the movement of the glazing bead 3 relative to the core 11.

This central region can result, for example, from a longitudinal V-shaped groove on an inner inner side of the joint 31, as illustrated in the enlargement of FIG. 3. The joint 31 thus forms a hinge between the core 11 and glazing bead 3.

According to an advantageous possibility, this longitudinal groove may include bearing portions 311, for example bulges on each of its edges. These bulges illustrated by dotted lines on the enlargement of FIG. 3 advantageously make it possible to form a blocking point in the closed position of the glazing bead.

3. Such a blocking point makes it possible to avoid deformation or displacement of the articulation 31 during cutting-off of the latter in the closed position. The level of finish of the core profile 10 after cutting is therefore improved.

The glazing bead 3 can be locked against the core 11 in the closed position by a closure system, for example with a clip.

The glazing bead 3 preferably comprises on an internal face a curved longitudinal tubular part 32 advantageously configured to guide the rotational movement of the glazing bead 3 between the open position and the closed position.

This tubular part 32 can advantageously form a first element of the closure system. It can for example fit into a housing formed on the outer face 112 of the core 11.

In particular, this housing can be defined by the external face 112, the lower bar 310 and an upper bar 320 preferably carried by the external face 112, in the extension of the upper face 110.

The upper bar 320 can advantageously form a second element of the closure system. It may in particular comprise on a free end a lug 321 configured to maintain the glazing bead 3 in the closed position, for example by cooperating with a recess 322 of the tubular part 32.

The free end of the upper bar 320 can also be extended so as to form a fulcrum 324 for the glazing bead 3 in the closed position, as illustrated by the dotted lines in FIG. 3. This extension can be in one hard plastic material or one having low flexibility, so as to accommodate small relative deformations of the assembly glazing bead 3, articulation 31, and closure system.

The tubular part 32 may include one or more stops 323 configured to bear within the housing so as to block and stabilize the glazing bead 3 in the closed position.

For example, a first stop 323 can be located at the end of the nose formed by the tubular part 32, so as to bear on the external face 112. The first stop 323 and the recess 322 therefore make it possible to block a translational movement. horizontal along the axis y of the tubular part 32, in the closed position.

A second stop 323 can be located on a lower part of the nose formed by the tubular part 32, so as to bear on the lower bar 310. The second stop 323 and the recess 322 therefore make it possible to block a movement of vertical translation of the tubular part 32, in the closed position.

The stops 323 preferably form punctual supports respectively in cross section. Consequently, a slight elastic deformation can advantageously occur at the level of these point supports in the closed position, thus optimizing the blocking and the stability of the glazing bead 3.

The glazing bead 3 is preferably made of PVC or based on PVC.

The glazing bead 3 may include a seal or a flexible lip 123 configured to seal between the glazing bead 3 and the glazing in the closed position.

The flexible sealing lip 123 can also be configured to ensure sealing between the glazing bead 3 and a flap 50 of the frame 5, in particular in the case of an opening 1 hidden by the frame 5, as illustrated in Figure 4.

For example, in cross section as illustrated in FIG. 4, the glazing bead 3 extends along z and the flexible sealing lip 123 extends mainly along y to seal between the glazing bead 3 and the glazing d on the one hand, and the seal between the glazing bead 3 and the flap 50 on the other hand.

This flexible sealing lip 123 is preferably located at a second end of the glazing bead 3, opposite the first end.

This flexible sealing lip is for example made of flexible PVC coextruded with the glazing bead 3. Alternatively, it can be made of EPDM or post extruded TPE and attached to the glazing bead 3, so that it can be replaced over time in the event of deterioration. .

More precisely, the joinery is configured so that when the leaf 1 is pressed against the frame 5, the frame 5 masks the whole glazing strip 3, or, at least covers the glazing strip 3 enough to leave only a width of glazing strip visible less than or equal to 2 centimeters (cm, 10 ′ ² meters) and preferably less than or equal to 1 cm and preferably less than or equal to 0.5 cm. The width of the glazing bead is measured in a plane zx parallel to the glazing 2 and in a direction perpendicular to the direction in which the glazing bead 3 mainly extends.

In FIG. 4, the width of glazing bead 3 is therefore measured in the direction z of the orthogonal coordinate system xyz.

Preferably, and as illustrated in FIG. 4, the frame 5 covers the entire glazing bead 3 and rests on the flexible sealing lip 123 carried by the glazing bead 3. Thus, the flap 50 extends up to the flexible lip d 123.

According to another embodiment, not shown, the flexible sealing lip 123 is carried by the frame 5, for example the flap 50. The flexible sealing lip 123 is then applied against the glazing 2 when the leaf 1 is closed on the frame 5.

The core 11, the wedging part 12, the assembly part 13, the groove 14, the joint 31, the glazing bead 3 and the flexible sealing lips 121, 123 are preferably based on coextrudable thermoplastic materials.

The core profile 10 as illustrated in FIG. 2 can therefore advantageously be produced at the end of a single coextrusion step.

This makes it possible to reduce production times and / or reduce production costs by reducing the number of steps necessary for the production of a sash frame comprising a core 11 and a glazing bead 3.

This also makes it possible to optimize the connections between the glazing bead 3, the articulation 31 and the core 11.

Such a profile 10 can then be cut, covered and assembled by means of brackets 131, 132 for example. To this end, the core 11 forms a housing inside which the branch of a bracket 132 can be inserted.

In particular, an aluminum structural profile 130 can be crimped and / or ultrasonically welded to the assembly part 13, so as to cover at least one inner side of the sash frame 1.

The structural profile 130 preferably comprises at a lower part a tubular seal 133 configured to seal between the opening frame 1 and the standing frame 5 (Figures 3 and 4).

As illustrated in FIG. 4, a wedge 210 of semi-rigid glazing or an intermediate expansion joint can be put in place on the upper face 110 of the core 11, so as to support the glazing 2 and to tolerate differences in thermal expansion between the glazing 2 and the opening frame 1.

This wedge 210 preferably has a deformable hook or clip configured to cooperate by interlocking with the groove 122 of the wedging part 12, so as to hold the wedge 210 in place.

The invention also relates to a method for producing and assembling the sash frame 1, illustrated by FIGS. 5A to 5E, and preferably comprising the following steps:

- Coextrude the profile 10 based on PVC, so as to obtain a glazing bead 3 secured to the core 11 in PVC by means of a joint 31 in TPE (FIG. 5A); at the outlet of the extruder, the glazing bead 3 can be in an open position illustrated in FIG. 5B where the nose of the tubular part 32 bears against the upper bar 320, due to the relaxation of the articulation 31 for example ,

- Assemble the profile 10 based on PVC and the structural profile 130 in aluminum, preferably by crimping; glazing bead 3 can be in the open position,

Fold down the glazing bead 3 to the closed position (Figure 5C),

- Cutting and / or machining the assembled profiles 10, 130, in the closed position of the glazing bead,

- Assemble the sash frame 1, using brackets 131, 132 and / or by welding,

Optionally, mount the accessories in the groove 14 of the sash frame 1,

Open glazing bead 3,

Optionally, install the glazing shims 210,

Fit the glazing 2 (Figure 5D),

Fold down the glazing bead 3 in the closed position, so as to hold the glazing 2 in place in the sash frame 1 (FIG. 5E).

The invention is not limited to the embodiments described above but extends to all embodiments falling within the scope of the claims.
