Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of sliding doors. It finds a particularly advantageous application in the field of building construction, and in particular sliding doors or windows.

STATE OF THE ART

In general, a sliding leaf comprises a fixed frame, fixed to a wall of a building and at least two leaves sliding relative to the fixed frame. The fixed frame is arranged in a substantially vertical plane in the mounted position of the leaf and has sections forming respectively upper and lower crosspieces, and two uprights each extending vertically from the lower crosspiece to the upper crosspiece. These profiles define an internal space in which the leaves are engondés so as to be positioned on the rails of the frame.

Most of these openings are at the interface between the exterior and the interior of a building. Therefore, the profiles of the fixed frame have an inner part facing the interior of the building and an outer part facing outwards. As these profiles are metallic, and in particular aluminum, there may be a thermal bridge between their interior and exterior parts. In order to allow at least thermal insulation between the inner and outer parts of the profile, a thermal insulation device is inserted therein, and in particular at the level of the upper crosspiece.

The solution generally used is the insertion of a thermal insulation device comprising two rigid sections, usually made of extruded polyvinyl chloride (PVC), also called rigid PVC, aligned with each other and connected to the center of the upper crosspiece by an intermediate junction piece whose function is to contribute to sealing in the area in which the ends of two vents face each other when the sash is in the closed position.

When mounting the leaf, the leaves are generally engondated in the frame by presenting each leaf inclined with respect to the frame, and by inserting an upper profile of the leaf into the upper crosspiece of the frame. Then, the leaf is straightened so as to be aligned with the uprights of the frame, to be positioned on the rail of the lower crosspiece of the frame.

Since the profiles of the thermal insulation device are rigid, they must be removed from the upper crosspiece during the step of engondating the leaves. The intermediate junction piece is also removed. Once the leaves have been inserted into the frame, the installer then repositions the profiles with the intermediate joining piece. This solution is relatively long and complex to implement, and has a significant cost. Furthermore, this type of solution has poor thermal insulation and wind insulation performance.

In addition, over time, the leaves sometimes come to rub against the profiles of the thermal insulation device, which hinders the sliding of the leaves in the opening. This can for example be induced by a lack of parallelism created during the assembly of the opening, and/or during the aging of the opening, or even of the building. To limit this friction, it turns out that, very often, professionals remove the PVC profiles. The thermal insulation performance is then significantly deteriorated.

Other solutions have been considered which include integrating foam elements. In practice, it turns out that the service life and performance of these solutions are very limited. This lack of reliability has not allowed these solutions to emerge on the market.

An object of the present invention is therefore to propose a solution making it possible to obtain good thermal insulation, or even improved insulation, while facilitating the manufacture and assembly of a sliding leaf. A non-limiting objective of the invention may also be to obtain good thermal insulation, or even improved insulation, with a longer lifespan than existing solutions.

The other objects, features and advantages of the present invention will become apparent from a review of the following description and the accompanying drawings. It is understood that other benefits may be incorporated.

SUMMARY OF THE INVENTION

• un cadre dormant, le cadre comprenant une traverse inférieure, une traverse supérieure, la traverse inférieure et la traverse supérieure s'étendant chacune selon une direction horizontale x, et deux montants disposés en vis-à-vis et s'étendant chacun selon une direction verticale z depuis la traverse inférieure jusqu'à la traverse supérieure,
• au moins un vantail monté coulissant dans le cadre selon une direction de coulissement parallèle à la direction horizontale x, l'au moins un vantail comprenant un profilé inférieur configuré pour coopérer avec la traverse inférieure, de préférence, le profilé inférieur est configuré pour coulisser sur un rail de la traverse inférieure, par exemple par l'intermédiaire d'au moins un chariot porté par l'un parmi le cadre et le vantail, et un profilé supérieur configuré pour coopérer avec la traverse supérieure, par exemple en étant guidé en coulissement par la traverse supérieure,
• un dispositif d'isolation fixé sur la traverse supérieure.

To achieve this objective, according to one embodiment, a sliding sash is provided comprising:

• a fixed frame, the frame comprising a lower crosspiece, an upper crosspiece, the lower crosspiece and the upper crosspiece each extending along a horizontal direction x, and two uprights arranged facing each other and each extending along a direction vertical z from the bottom rail to the top rail,
• at least one leaf mounted sliding in the frame in a direction of sliding parallel to the horizontal direction x, the at least one leaf comprising a lower profile configured to cooperate with the lower crosspiece, preferably, the lower profile is configured to slide on a rail of the lower crosspiece, for example via at least one carriage carried by one of the frame and the leaf, and an upper profile configured to cooperate with the upper crosspiece, for example by being guided in sliding by the upper crosspiece,
• an isolation device fixed to the upper crosspiece.

• présentant une face supérieure,
• s'étendant sur au moins 80% de la longueur de la traverse supérieure, la longueur de la traverse supérieure étant prise selon la direction horizontale x ou de façon équivalente, selon la direction de coulissement de l'au moins un vantail, et
• comprenant un corps en mousse, de préférence déformable et à mémoire de forme, et un film recouvrant au moins partiellement le corps, le film présentant un coefficient de friction inférieur à celui de la mousse du corps, le film formant une face inférieure pour le joint d'étanchéité.

The isolation device comprises a seal mounted on the upper crosspiece, the seal:

• having an upper surface,
• extending over at least 80% of the length of the upper crosspiece, the length of the upper crosspiece being taken in the horizontal direction x or equivalently, in the direction of sliding of the at least one leaf, and
• comprising a foam body, preferably deformable and with shape memory, and a film covering at least partially the body, the film having a coefficient of friction lower than that of the foam of the body, the film forming an underside for the joint sealing.

The insulation device is also configured so that the upper profile of the at least one leaf is, over at least 80% of the length of the at least one leaf, in contact with the lower face of the sealing joint , whatever the position of the sash when it slides in the frame.

When a sash slides in the sash, each upper sash profile is in contact with the seal and rubs on the film. Thus, this opening provides a seal along at least each upper section of the leaf. In addition, in the context of the development of the present invention, it has been found that surprisingly this insulation device has a very good robustness, in particular to tearing, when handling a leaf, and thus longer life compared to existing solutions.

This opening has particularly high performance in terms of thermal insulation. This opening can even have remarkable airtightness, watertightness and windtightness performance, hereinafter referred to as AEV tightness.

This opening provides continuous sealing, that is to say continuous sealing over at least 80% of the upper crosspiece. This solution thus differs radically from the known solutions which provide for a central part serving as a junction between two profiles of a PVC seal, or an intermediate junction part whose function is to contribute locally to sealing in the zone in which the ends two vents are facing each other when the sash is in the closed position.

In addition, this opening allows a manufacturing and a break greatly facilitated compared to existing solutions. In particular, it minimizes the number of parts necessary to achieve sealing and therefore reduces the complexity and cost of the opening. In addition, this opening allows the leaves to be engondée in the frame, without having to remove the insulation device, and more particularly the seal and the intermediate connecting piece.

The seal can be mounted on the upper crosspiece by fixing, and preferably by gluing, its upper face directly on the upper crosspiece. The seal can alternatively be mounted on the upper crosspiece by means of an additional part, such as an intermediate section, suitable for receiving the seal and for being fixed, for example by clipping, on the top rail. It is therefore understood that the mounting of the seal on the upper crosspiece can be direct between the seal and the upper crosspiece, or indirect via this additional part.

A second aspect of the invention relates to a method of manufacturing a profile intended to form an upper crosspiece of a sliding leaf, comprising the fixing of an insulation device on a profile, said fixing comprising the mounting of a seal on the profile, the seal comprising a foam body, preferably deformable and with shape memory, and a film covering at least partially the body, the film having a coefficient of friction lower than that of the body foam, the film forming an underside for the gasket.

The assembly of the sealing joint on the profile, prior to a possible cutting of the profile and the joint, allows the manufacture of the assembly formed by the profile and the joint, possibly supplemented by an intermediate profile, on a format of standard factory. For example, sets of 6.5 linear meters can be produced. The method of manufacturing the profile intended to form the upper crosspiece is thus facilitated, and its cost is reduced. an insulation device is thus an insulation device is thus facilitated, and its cost is reduced.

• le tronçonnage du profilé pour réduire la longueur du profilé de façon à former au moins une traverse supérieure de l'ouvrant, et de préférence plusieurs traverses supérieures, le joint d'étanchéité s'étendant sur au moins 80% de la longueur de la traverse supérieure,

A third aspect of the invention relates to a method for mounting a sliding sash, comprising:

• the provision of a profile intended to form a top rail comprising an insulation device fixed to the profile, the insulation device comprising a sealing joint, the sealing joint comprising a foam body, preferably deformable and with shape memory, and a film covering at least partially the body, the film having a coefficient of friction lower than that of the foam of the body, the film forming an underside for the seal,
• the cutting of the profile to reduce the length of the profile so as to form at least one upper crosspiece of the opening, and preferably several upper crosspieces, the sealing joint extending over at least 80% of the length of the crosspiece superior,
• the assembly of a fixed frame by assembling the upper crosspiece, a lower crosspiece and two uprights,
• the engondage of at least one leaf in the frame, the engonage comprising:
• the introduction of the at least one leaf in the upper crosspiece by presenting the at least one leaf inclined with respect to the frame, and by compressing the body of the seal by the leaf, then
• the introduction of the at least one leaf into the lower crosspiece, so as to arrange the at least one leaf in a sliding position of the leaf in the frame, the upper section of the at least one leaf being in contact, in the sliding position, with the underside of the seal.

According to one example, the upper profile of the at least one leaf is, over at least 80% of the length of the at least one leaf, in contact, in the sliding position, with the lower face of the seal whatever the position of the sash when it slides in the frame.

This method makes it possible to mount the opening according to the characteristics set out above.

If the seal is glued in the upper crosspiece, this gluing step is preferably carried out, before delivery to the company which carries out the assembly and installation of the frame of the opening.

If the seal is glued in the intermediate section, the latter can be fixed to the upper crosspiece before delivery to the company which carries out the assembly and installation of the opening frame. Alternatively, the intermediate profile can be fixed to the upper crosspiece by the company which carries out the assembly and installation of the sash frame.

Thanks to the sectioning of the section intended to form the upper crosspiece, the dimensioning of the upper crosspiece with its sealing joint can be carried out in a workshop of the team which installs the opening, or even on the place of assembly of the opening. . This sizing can therefore be made to measure by the manufacturer or the sash fitter. The method therefore allows a gain in productivity on the manufacture of the leaf.

The drawings are given by way of examples and do not limit the invention. They constitute schematic representations of principle intended to facilitate understanding of the invention and are not necessarily at the scale of practical applications. In particular, the number of leaves, as well as the relative dimensions of the sealing device and of the upper crosspiece are not necessarily representative of reality.

DETAILED DESCRIPTION OF THE INVENTION

Before starting a detailed review of embodiments of the first aspect of the invention, optional characteristics are set out below which may optionally be used in combination or alternatively.

According to one example, the foam body is deformable, and preferably elastically deformable. In particular, the foam can deform to allow the sash to be engondated in the frame during assembly of the sash, while returning at least partly to its initial position to ensure contact between the seal and the leaf during sliding of the latter in the frame. According to one example, the foam body is deformable and has shape memory. Alternatively, provision may be made for the foam body to be deformable without having shape memory.

According to one example, the seal extends over the entire length of the upper crosspiece. Thus, the seal is continuous over the entire length of the upper crosspiece. The thermal insulation device may also consist only of the seal. The insulation performance of the opening can thus be improved at a lower cost and with even easier assembly.

According to one example, the body of the seal is configured so as to present a first compression configuration in which the foam body is compressed, at least vertically to the upper profile of the at least one leaf, whatever the position of the at least one leaf during its sliding in the frame. According to one example, the body of the seal is configured so as to present a second compression configuration, in which the foam body is compressed, at least vertically to the upper profile of the at least one leaf, during a engondage of at least one leaf in the opening, the second configuration being more compressed than the first configuration.

According to one example, the body of the seal has a configuration of maximum compression, in which the body of the seal is compressed by at least 40% and preferably by at least 60% and preferably by at least 80% of its thickness when the seal body is uncompressed. In the present description, the thickness of the seal is taken in the vertical direction z. According to one example, the body of the seal has a compressibility such that, under a force to engonge the at least one leaf exerted manually by two operators, the body of the seal is compressed by more than 40% , preferably more than 60% and preferably 80% of its thickness when the body of the seal is uncompressed.

Preferably, the body of the seal is formed of a low density shape memory foam, and more preferably of a density of less than 35 kg.m ^-3 , preferably less than 30 kg.m ^-3 , and preferably between 25 and 29 kg.m ^-3 . According to one example, the film has a lower hardness than the hardness of the extruded polyvinyl chloride. Typically this hardness is a Shore D hardness. Preferably, the film can be deformed by pressure exerted by a user's finger.

According to one example, the film has a coefficient of friction lower than that of extruded polyvinyl chloride.

According to one example, the film has a breaking strength greater than 20 MPa, preferably greater than 25 MPa. Thus, the risk of the film tearing is minimized, or even avoided, when mounting the opening and/or when sliding the leaf or leaves.

According to one example, the film is based on polytetrafluoroethylene or its derivatives, abbreviated PTFE in the following.

According to one example, the film is based on polyethylene terephthalate or its derivatives, abbreviated PET in the following.

According to one example, the seal is free of extruded polyvinyl chloride. According to one example, the body of the seal has in its cross section two flanks separated by a lower face. The lower face is turned towards the ground. The film covering substantially the entire underside of the body. Preferably it does not extend over the two sides of the body. Preferably, the film covers only the underside of the body of the seal.

According to one example, the body of the seal and the film form a one-piece assembly, preferably the body of the seal and the film do not have any discontinuity over the length of extension of the seal on the crosspiece superior.

According to one example, the upper crosspiece has at least two guide rails for the at least one leaf, said rails being parallel and extending mainly in the direction of sliding of the at least one leaf, and at least one groove located between said rails. The at least one groove may further be delimited by a bottom and two side walls.

According to one example, the insulation device may comprise an intermediate profile forming a groove delimited by a bottom and two side walls, the upper face of the seal being fixed, and preferably glued, to the bottom of the groove. The intermediate profile can be adapted to be fixed, for example by clipping, in the groove of the upper crosspiece.

Thus, the intermediate profile forms a stretcher carrying the seal. Preferably, the intermediate profile has a "U" shape in section. The bottom of the "U" defines the bottom of the groove.

This embodiment has the advantage of considerably relaxing the constraints of fixing the seal. In fact, for bonding to be effective, particularly over time, it must take place in a rigorously controlled environment, particularly in terms of temperature, humidity and humidity. rate of particles such as dust. A sash frame assembly workshop, usually available to companies that fit these sashes to the end customer, is neither designed nor capable of guaranteeing this rigorous environmental control. In the context of the development of the present invention, it has been observed that the bonding carried out in this type of workshop leads to premature tearing off of the seals when handling the leaves.

The proposed embodiment, consisting in adding to the upper crosspiece, preferably by clipping, an intermediate piece, preferably made of PVC, and in which the seal is glued, makes it possible to avoid these problems. Indeed, the bonding of the seal in the intermediate part can be carried out in a perfectly controlled environment, thus guaranteeing the performance of the bonding. The intermediate piece provided with the seal can then be delivered to the company which assembles the frame and installs the sash. During this delivery, the intermediate piece may already be integrated into the profile intended to form the upper crosspiece. Alternatively, the intermediate piece can be delivered separately, the company which carries out the assembly of the frame then being able to carry out the fixing, preferably by clipping, of the intermediate piece inside the upper crosspiece.

In addition, the intermediate part, more precisely the bottom of its groove, has a continuity of material over its entire length. The bonding interface between the intermediate piece and the seal is therefore continuous, which contributes to effective bonding. Conversely, if a strip of foam is bonded directly in contact with an upper crosspiece, the bonding interface may have discontinuities at the interface between the two sections forming a thermal break. In the context of the development of the present invention, it has been observed that this discontinuity of the interface often leads to an increase in the risk of tearing off a seal and therefore to a reduction in the service life of the opening.

Furthermore, this embodiment makes it possible to considerably simplify the maintenance and after-sales service of such an opening. Indeed, if the seal needs to be replaced, the operator can easily remove the intermediate part by unclipping it from the upper crosspiece and then replace it with another intermediate part fitted with an appropriate seal.

According to one example, each side wall of the intermediate section has an internal face in contact with or facing a side of the seal and an external face, opposite the internal face, the external face carrying at least one relief configured to cooperate with a relief of the upper crosspiece so as to allow the clipping of the intermediate profile on the upper crosspiece.

According to one example, the upper crosspiece has at least two guide rails for the at least one leaf, said rails being parallel and extending in the direction of sliding of the at least one leaf. At least one groove can be located between said rails, the at least one groove further being delimited by a bottom and two side walls. The upper face of the seal can be fixed, preferably glued, to the bottom of the groove. The bottom of the groove thus serves as a rigid support for the seal. Each side wall is preferably formed by a rail.

According to one example, the seal extends transversely from one side wall to the other of the two side walls of the at least one groove. The seal may extend over at least 90%, and preferably over at least 95%, of a distance between each side wall, the distance between each side wall being taken along a direction y perpendicular to the horizontal direction x. Synergistically with the relative dimensions of the body of the seal and of the film, the seal thus perfectly fills the groove, ensuring optimum sealing of the opening at the level of its upper crosspiece.

Optional features of the second aspect of the invention are set out below, which may optionally be used in combination or alternatively.

According to one example, the mounting of the seal comprises the bonding of an upper face of the seal to an intermediate profile, then the fixing, for example by clipping, of the intermediate profile on the profile intended to form the upper crosspiece .

According to one example, the assembly of the seal is carried out by gluing the upper face of the seal on the profile intended to form the upper crosspiece. According to one example, the assembly of the seal is configured so that the seal extends over the entire length of the profile intended to form the upper crosspiece.

Optional features of the third aspect of the invention are set out below, which may optionally be used in combination or alternatively.

According to one example, the method of mounting the opening is free of a step of removing the seal between the mounting of the frame and the engondage of at least one leaf in the frame. The assembly of the opening is thus facilitated and the manufacturing cost of the opening is reduced. Furthermore, the risk of damage to the seal sealing is minimized, or even avoided, improving the life of the sash. The risk of deterioration of thermal insulation performance is also limited, or even avoided. According to one example, during the engondage of at least one leaf, the compression of the body of the seal by the leaf is carried out manually by an operator. In the rest of the description, use will be made of terms such as "vertical", "longitudinal", "transverse", "upper", "lower", "front", "rear", "above", "below". . These terms should be interpreted relatively in relation to the normal position of use of the sliding sash. For example, in the case where the opening is intended to be fixed vertically on a wall, the upper faces of the elements of the opening correspond to the faces of the elements which face upwards. In the following, we refer to the case where the normal position of use of the sash is vertical

The term “one-piece assembly” is understood to mean an assembly in one piece, of or in an equivalent manner forming a block.

By extruded PVC or rigid PVC is meant polyvinyl chloride or one of its derivatives used for the manufacture of profiles and tubes by extrusion. Rigid PVC is differentiated from flexible PVC, also called plasticized PVC, and differentiated from expanded PVC. A parameter “substantially equal to/greater than/less than” a given value means that this parameter is equal to/greater than/less than the given value, to within plus or minus 10%, or even within plus or minus 5%, of this value.

An element “based” on a material A is understood to mean an element comprising this material A and possibly other materials, for example additives.

The sliding sash 1 is now described with reference to the figures 1 to 4 . As illustrated in figure 1 , the sliding leaf 1 comprises a fixed frame 10, fixed to a wall 2, for example of a building. The fixed frame 10 is preferably arranged in a substantially vertical plane in the mounted position of the opening 1. The frame 10 comprises sections forming a lower crosspiece 100 and an upper crosspiece 101, each of the crosspieces 100, 101 extending along a horizontal direction x. The frame 10 further comprises two uprights 202 each extending in a vertical direction z, from the lower crosspiece 100 to the upper crosspiece 101. The sliding leaf 1 comprises at least one leaf 11 configured to slide in the horizontal direction x, or equivalently in the direction of main extension of the crosspieces 100, 101. In the following, it is considered in a non-limiting manner that the sliding leaf 1 comprises two sliding leaves.

In a sliding position, each leaf 11 can slide in the horizontal direction x between a closed position and a fully open position of the leaf 1, passing through a plurality of opening positions of the leaf 1. For this, each leaf 11 comprises a lower profile 110 configured to cooperate with the lower crosspiece 100 of the frame 10. According to one example, the lower profile 110 can be configured to slide on a rail of the lower crosspiece 110, for example by the intermediary of a running carriage carried by one of the frame and the leaf, the running carriage comprising at least one roller. In addition, each leaf 11 comprises an upper section 111 configured to cooperate with the upper crosspiece 101. According to one example, the upper section 111 is slidably guided by the upper crosspiece 101.

Each leaf can further comprise a central upright 113, as well as a peripheral upright 114. The closing position of the opening is now described in the example illustrated in figure 2 . When the leaf 11 is in the closing position of the leaf, the peripheral upright 114 of each leaf can be brought into abutment against an upright 102 of the frame. In addition, the central uprights 113 of the two leaves are positioned at least partially opposite in a transverse direction y. The central amounts 113 are configured to cooperate in order to ensure a certain sealing. To this end, provision may be made for the central uprights 113 to carry complementary reliefs which ensure engagement of the leaves to ensure sliding abutment and contacting of the seals. These reliefs are illustrated in figure 2 in the form of a baffle 13.

Each leaf 11 can slide in the horizontal direction x between the closed position and the fully open position of the leaf 1, in which the central upright 113 of the leaf can come into abutment on an upright 102 of the frame 10.

In order to place each leaf 11 in a sliding position during engondage of the leaves, described in more detail later, the upper crosspiece 101 comprises a groove 1011, as illustrated in picture 3 . This groove 1011 being able to be the place of a thermal transfer on either side of the opening 1, the opening 1 further comprises a thermal insulation device 12, inserted at the level of the upper crosspiece 101, and more particularly in this groove 1011. This sealing device 12 is configured to allow at least thermal insulation on either side of the opening 1 over the length of the upper crosspiece 101. This length is taken in the horizontal direction x , or equivalently according to the direction of sliding of the leaves 11. This device 12 can also provide AEV sealing, and in particular against air and wind.

For this, the device 12 comprises a seal 120 extending over at least 80% of the length of the upper crosspiece 101. The greater the length of extension of the seal 120, the greater the length of the a possible thermal bridge at the level of the upper crosspiece, in the horizontal direction x, is reduced. Preferably, the seal 120 extends substantially over the entire length of the top rail 101, as illustrated in figure 2 . Thus, the sealing can be continuous over the entire length of the upper crosspiece 101, and more particularly from one upright 102 to the other upright 102 of the opening 1.

Furthermore, according to a preferred embodiment, the seal 120 has no discontinuity along the horizontal direction x. The insulation device 12 may in particular comprise a single seal 120. The opening 1 is thus free of a central part serving as a junction between a plurality of seals 120. The insulation device 12 thus comprises a reduced number of parts necessary to achieve the insulation, or even comprises only one part. The complexity and the cost of the opening 1 are therefore reduced, while maintaining good thermal insulation performance.

The seal 120 is now described in more detail with reference to the figure 3 , 8 and 9A . According to one example, the seal 120 has an upper face 1201 fixed to the upper crosspiece 101, as for example illustrated in picture 3 . Preferably, the upper face 1201 of the seal 120 is glued to the upper crosspiece 101, ensuring a more robust fixing of the seal 120 than simply clipping the seal 120 into the crosspiece 101.

Preferably, according to another example illustrated by the figure 8 and 9A , the sealing device 12 may comprise an intermediate profile 121, configured to at least partially accommodate the seal 120, and to be fixed, for example by clipping, to the upper crosspiece 101. The intermediate profile allows good mastery of the interface between the upper crosspiece 101 and the profile 101. In addition, this makes it possible to avoid sticking the seal 120 on the site of manufacture or installation of the carpentry, as described more in detail later. For this, the intermediate profile 121 is preferably a U-shaped part. It thus forms a stretcher for the seal 12. Preferably, the seal 120 is glued to the profile 121. The fixing of the seal sealing 120 on the intermediate section 121, the latter being mounted on the upper crosspiece 101, allows a better reliability of fixing and a better robustness of the sealing device 12.

In addition, the seal 120 is configured so that the upper profile 111 of each leaf 11 is in contact with the lower face 1200 of the seal 120, over at least 80% of its length, and preferably over substantially its entire length, this length being taken in the horizontal direction x. Thus, this configuration makes it possible to ensure at least optimal thermal insulation, leaving no free space between the upper crosspiece 101 and the upper section 111 of each leaf 11. The sealing gasket 120 further extends over at least 80% of the length of the upper crosspiece 101, it is understood that this insulation can be obtained whatever the position of each leaf 11 during its sliding in the frame 10.

In order to allow the slings 11 to be engondage in the groove 1011 while ensuring this optimum and running insulation along the upper crosspiece 101, the seal 120 comprises a body 1202 made of deformable foam. The body 1202 is made of deformable foam so as to allow the engondage of the leaf 11 in the frame 10 during the assembly of the leaf 1, while making it possible to ensure contact between the seal 120 and the leaf 11 during the sliding of the latter in the frame 10. Preferably, the foam of the body 1202 is shape memory, so that once the foam body 1202 is deformed, the body 1202 of the seal 120 tends to redeploy either in a configuration of maximum authorized deployment, or in its initial configuration.

Preferably, the opening 1 is configured so that the body 1202 of the seal 120 has a first configuration and a second configuration in compression. In the first compression configuration, the foam body 1202 can be compressed at least vertically to the upper section 111 of each leaf 11, when the leaf 11 is in a sliding position in the opening 1. This configuration can be illustrated over there picture 3 . Indeed, the body 1202 of the gasket 120 being made of foam, the gasket 120 can be compressed against the upper profile 111 of each leaf 11, including in the event of slight variations in the distance between the upper crosspiece 101 and the upper profile 111 of each leaf. Thus, the thermal insulation can be maintained despite the manufacturing tolerances, and despite aging of the opening 1, or even of the building, causing a slight deflection or subsidence of the latter. In addition, these variations make it possible to maintain good sealing of the sash after adjustment of the height position of the sash, which adjustment is often necessary to correct a lack of flatness of the fixed frame.

In the first compression configuration, the foam body 1202 can be compressed vertically from the upper section 111 of each leaf 11, over a range of positions of the leaf, when the leaf 11 is in a sliding position. The position of the leaf 11 can be adjusted between a plurality of positions while maintaining compression of the seal 120, and thus good sealing of the leaf.

The figure 9A , 9B and 9C illustrate by way of example a leaf 11 in a respectively nominal, low and high position. The compression of the seal can be modulated according to the position of the leaf 11, temple to adjust the parallelism of the leaves inside the fixed frame. This adjustment is carried out for example by means of adjustment screws at the level of support rollers of the leaves on the rails of the fixed frame.

According to an example in which the seal has a height in the direction z of substantially 17 mm, in the nominal position of the leaf 11 in figure 9A , the seal 120 is compressed by the leaf 11 over a distance D4 of substantially 2 to 2.5 mm. In the lower position of leaf 11 in Figure 9B , the seal 120 can be compressed by the leaf 11 over a distance D5 of substantially 0.5 to 1 mm. In the high position of the leaf 11 in Figure 9B , the seal 120 can be compressed by the leaf 11 over a distance D6 of substantially 5 to 5.5 mm.

In the context of the development of the present invention, it has been found that for each of these positions, the sealing is particularly efficient and the behavior of the seal 120 remains particularly efficient even after very many opening and closing cycles. leaves. In particular, even in the most compressed position, the seal 12 does not tear off from the upper crosspiece 101 thanks to the means which make it possible to reduce fiction and which will be detailed below.

In the second compression configuration, the foam body 1202 can be compressed, at least vertically to the upper section 111 of each leaf 11, the seal 120 being more compressed in the second configuration than in the first configuration, as illustrated in the figure 7 . The second configuration in compression can in particular allow the engondage of each leaf 11 in the opening 1, as described later. Thus, when engondage of each leaf 11, the foam body 1202 of the gasket can be compressed with little or no risk of breakage or rupture.

Preferably, the foam body 1202 has a maximum compression configuration, wherein the body 1202 is compressed at least 40%, preferably at least 60%, and preferably at least 80% of its thickness when the gasket is not compressed, this thickness being taken in the vertical direction z. For this, the body 1202 can be formed of a low density foam, and more preferably of a density substantially less than 30 kg.m ^-3 , and preferably between 25 and 29 kg.m ^-3 .

In the sliding position of each leaf 11, the seal 120 comprises a film 1203 configured to minimize the friction of the seal with the upper section 111. The film 1203 also has a coefficient of friction lower than that of the foam of the body 1202. For this, the film 1203 forms the lower face 1200 of the seal 120. The film can extend substantially over the entire contact surface between the seal 120 and the upper section 111, and preferably over the entire underside 1202b of the foam body 1202. When each leaf 11 slides in the horizontal direction x in the opening 1, it is understood that the risk of snagging, or even tearing, of the foam body 1202 is limited, which improves the resistance and the life of the device. insulation 12. Preferably, the film 1203 also has a coefficient of friction lower than that of extruded PVC. More preferably, the film 1203 has a coefficient of friction substantially less than 0.2, and preferably substantially less than 0.15, more preferably still substantially equal to 0.13.

The film 1203 may also have tear-resistant properties in order to minimize, or even avoid, snagging and/or tearing of the film 1203 when each leaf slides in the horizontal direction x in the opening 1. More particularly, the film 1203 may have a breaking strength substantially greater than 20 MPa, and preferably substantially greater than 25 MPa. The film 1203 thus has breaking strength properties greater than that of extruded PVC, the breaking strength of which is approximately 8 MPa.

The 1203 film may have a lower hardness than the hardness of extruded PVC. Typically, the 1203 film is based on a material whose Shore D hardness is lower than that of extruded PVC. According to one example, the film 1203 is based on a material whose Shore D hardness is substantially less than 70, for example PTFE.

More preferably still, the film is then deformable by pressure exerted by the finger of an operator. Synergistically with the compression capacity of the body 1202 of the seal 120, the previously stated characteristics of the film 1203 allow effortless compression of the seal 120, while limiting the risk of degradation of the seal 120 during assembly. of the opening 1 and during the sliding of the leaves. According to another example, the film is rigid, preferably the film cannot be deformed by pressure exerted by the finger of an operator. According to this example, the film is a PET film.

The film 1203 can more particularly be a film of PTFE, this film 1203 having very good tear-resistant properties, deformation properties and a low coefficient of friction. According to another example, the film 1203 can more particularly be a PET film, this film 1203 having a good compromise between good anti-tear properties, as well as coefficient of friction, more rigid than PTFE but having a lower cost compared to cost of PTFE. Preferably, the film 1203 has a thickness substantially equal to 300 μm.

According to a particular embodiment, the body 1202 of the gasket 120 and the film 1203 form a one-piece assembly. Preferably, the body 1202 and the film 1203 do not have any discontinuity over the entire extension length of the seal 120 on the upper crosspiece 101. Thus, the risk of separation of the body 1202 and the film 1203 is limited. The film 1203 may also not extend beyond the sides 1202a of the body 1202 of the seal 120, in the transverse direction y. These characteristics make it possible to further limit the creation of possible snagging points which may induce deterioration of the seal 120 during the assembly of the opening and during the sliding of the leaves 11. In addition, the film 1203 may not s 'extend on the sides 1202a of the body 1202 of the gasket 120. According to one example, the body 1202 and the film 1203 can be formed as a multilayer assembly in an extruder.

By way of illustration, a more detailed example of the upper part of the opening 1 is now described with reference to the figure 1 and 3 .

According to this example, the upper crosspiece 101 can comprise an inner sub-profile 101a extending along the horizontal direction x between the two uprights 102 of the opening 1. The inner sub-profile 101a can be fixed, for example by clipping , to one or even several outer sub-profiles 101b to form the upper crosspiece 101. Typically, the inner sub-profile 101a is made of plastic such as PVC and the outer sub-profiles 101b are made of aluminum. The inner sub-profile 101a is clamped between the outer sub-profiles 101b. The inner sub-profile 101a thus acts as a thermal bridge break profile and the outer sub-profiles 101b define the outer and inner profiles of the upper crosspiece 111.

The upper crosspiece 101 may further comprise two parallel rails between them and extending in a direction parallel to the horizontal direction x between the two uprights 102 of the opening 1. According to the example illustrated in picture 3 , the assembly of the inner sub-profile 101a with the outer sub-profile 101b has a projection in the vertical direction z. This projection can extend along the horizontal direction x between the two uprights 102 of the opening 1, forming the rail 1010.

According to this example, the opening 1 comprises two leaves 11 whose upper sections 111 are configured to slide along the rails 1010 in a horizontal direction x. This sliding is ensured by rollers mounted in rotation on the upper profile 111 and which roll on the rails 1010. For reasons of clarity, the rollers are not shown in the figures.

Each upper profile 111 comprises a bead 1110. The bead 1110 can be fixed on a support profile 1111, for example by clipping. It rests on the glazing 112, preferably via a gasket 1112a mounted on the glazing 112. The sealing gasket 1112a can in particular be configured to enclose the glazing 112, around an insert 1120.

The support profile 1111 can also carry seals 1111a, one end 1111b of each of these seals 1111a coming into contact with the upper crosspiece 101, in order to provide a seal during sliding.

The distance D1 between the rails 1010 as well as the dimensions of the upper section 111 of each leaf 11 can be chosen so that the upper sections 111 are separated by a distance D2 in the transverse direction y.

According to this example, the two rails 1010 are also separated by a distance D1 along a direction parallel to the transverse direction y. The upper crosspiece 101 thus comprises a groove 1011 having a bottom 1011a and side walls 1011b, the side walls being formed by the two rails 1010.

The seal 120 can be placed in the groove 1011. The upper face 1201 of the seal 120 can be fixed, and preferably glued, to the bottom 1011a of the groove 1011. The upper face 1201 of the seal 120 is thus in contact with the bottom 1011a of the groove 1011 over the entire length of the upper crosspiece 101, this length being taken in the horizontal direction x, as illustrated in figure 4 . Advantageously, the bottom 1011a of the groove 1011 is continuous. Preferably it is flat and has no discontinuity, preferably over the entire length of the upper crosspiece 101. The interface between the seal 120 and the upper crosspiece 101 is thus continuous, promoting efficient bonding. The seal 120 may also extend in the transverse direction y, from one side wall 1011a to the other of the groove 1011. The seal 120 may in particular extend over at least 90%, and preferably over at least 95% of the distance D1 between the two side walls 1011a. Thus, the upper crosspiece 101 facilitates the positioning of the seal 120 and contributes to its maintenance, and the seal 120 guarantees sufficient sealing. The seal 120 being housed in the groove 1011 between the bottom 1011a and the two side walls 1011b, the sides 1202a and the upper face 1201 of the seal 120 are protected by the upper crosspiece 101 during the assembly of the opening 1 and during its use. The width of the seal 120, taken along the transverse direction y, can also be substantially equal to the dimension of the width of the groove 1011 according to its cross section, within assembly tolerances.

As illustrated by the figure 8 and 9A , the seal 120 can be arranged in the intermediate profile 121 forming a groove 1210. The upper face 1201 of the seal 120 can be fixed, and preferably glued, to the bottom 1210a of the groove 1210a. The seal 120 being housed in the groove 1210 between the bottom 1210a and the two side walls 1210b, the flanks 1202a and the upper face 1201 of the seal 120 are protected by the intermediate profile 121 during the assembly of the opening 1 and during its use. The width of the seal 120, taken along the transverse direction y, can also be substantially equal to the dimension of the width of the groove 1210 according to its cross section, within assembly tolerances. According to one embodiment, the sides 1202a and the upper face 1201 of the seal 120 are glued to the side walls 1210b of the intermediate profile. According to one example, the intermediate profile 121 is an extruded PVC profile.

The insulation device 12, that is to say the assembly formed by the seal 120 and the intermediate profile 121, can be placed in the groove 1011 of the upper crosspiece 101. According to one example, the profile intermediate 121 is clipped into the groove 1011. Thus, a simple, fast and controlled fixing of the intermediate profile in the crosspiece 101 is ensured. For this, the intermediate profile 121 may have reliefs 1210ba complementary to reliefs of the upper crosspiece 101. Preferably the reliefs 1210ba are carried and preferably are formed by an outer face of each of the walls 1210b, the inner face of each of the walls 1210b being turned facing the seal 120.

According to one example, each internal wall is in contact with a side 1202a of the seal 120. According to one example, each internal wall is glued to the side 1202a of the seal 120. Alternatively the internal wall is not glued to the side 1202a of the seal 120.

Gasket 120, intermediate channel 121, and top rail 101 may be configured such that gasket 120 extends for at least 90%, and preferably for at least 95%, of the distance between the two side walls 1011a of the groove 1011 of the upper crosspiece 101, to guarantee sufficient sealing.

In the sliding position of the leaves 11, the seal 120 can be at least partially compressed in a first configuration by each upper profile 111. For this, as illustrated for example by the figures 1 to 3 and for each upper profile 111, the sliding guide 111a resting on the side wall of the rail 1010, corresponding to the side wall 1011b of the groove 1011, can also be resting on the lower face 1200 formed by the film 1203, so as to compress the seal 120. A portion of the glazing bead 1110 arranged facing the groove 1011 can also rest on the lower face 1200 formed by the film 1203, so as to compress the seal 120. The lower face 1200 of the seal 120 can be in contact with the glazing bead 1110 over the entire length of the upper profile 111, this length being taken in the horizontal direction x, as illustrated in figure 4 .

Furthermore, the relative dimensions of the upper section 111 of each leaf as well as of the upper crosspiece 101 can be chosen so that a portion of the lower face 1200 of the seal 120 is not in contact with the upper sections. 111. According to the example illustrated in picture 3 , the lower face 1200 of the seal 120 is not in contact with the upper sections 111 over a distance D3, taken in the transverse direction y, inducing the formation of a protrusion of the seal 120 between the two upper sections 111. Thus, the tightness of device 12 is further improved. A particular embodiment of the method of manufacturing a section 101' intended to form at least one upper crosspiece 101 of a sliding leaf 1, for example after cutting by a fitter for the fitting of the leaf, and comprising a device insulation 12, is now described with reference to the figures 5 and 6 . The section 101' intended to form at least one upper crosspiece 101, is referred to below as section 101'.

This method, typically carried out in the factory by the manufacturer of the section 101', comprises supplying a first section. This profile can typically be of a standard factory length, for example 6.5 linear meters, in its main direction of extension x. As illustrated in the figure 5 , this profile can be the inner sub-profile 101a, having a groove 1011 delimited by a bottom 1011a and side walls 1011b. This method further comprises the mounting of a seal 120, according to the characteristics described above, on this profile. The profile 101' can further comprise an outer sub-profile 101b fixed to the inner sub-profile 101a, for example by clipping. Alternatively, provision may be made for the seal to be mounted on the assembly formed by the inner sub-profile 101a and the outer sub-profile 101b. Preferably, the assembly of the seal 120 is carried out over the entire length of the profile 101'.

According to one example, the seal 120 can be fixed, and preferably glued, by its upper face 1201 on the bottom 1011a of the groove 1011 to form the profile 101'. For example, the seal 120 can be bonded to the inner sub-profile 101a at the factory after lacquering or at the factory using an extruder. For example, the seal 120 can be in the form of a roll, unrolled and glued to the inner sub-profile 101a.

According to another example, the seal 120 can be fixed, and preferably glued to the intermediate section 121 previously described, then the assembly formed by the seal 120 and the intermediate section 121 can be fixed on the upper crosspiece 101, and more particularly in the groove 1011 of the upper crosspiece 101, to form the profile 101'.

The bonding of the seal 120 can thus be carried out independently of the manufacture of the profile 101' or of the installation of the opening. The seal 120 can in particular be bonded to the intermediate section 121, under conditions of hygrometry and temperature determined to ensure good bonding. The seal 120 can for example be pressed into the intermediate section 121 of a standard factory length, for example 6.5 linear meters, by a press. During the development of the invention, it was demonstrated that the strength of the seal 120 and the robustness of the sealing device 12 were thus increased.

In the example shown in figures 9A to 9C , the upper crosspiece 101 comprises two profiles 101b separated by an inner profile 101a, the latter being formed by at least one and preferably two strips of polyamide 101ab. The groove 1011 is defined by the profiles 101b and one of the polyamide strips 101ab of the inner profile 101a. The walls 1011b of groove 1011 are defined by the profiles 101b. The bottom 1011a of the groove 1011 is defined partly by the profiles 101b and partly by the inner profile 101a. Thus the bottom 1011a of groove 1011 is not continuous. However, this poses no difficulty for the holding of the seal 120 since the latter is fixed to the upper crosspiece 101 by means of the intermediate profile 121 inside which it is housed. The intermediate profile 121 is preferably clipped onto the walls 1011b carried by the outer profiles 101b.

A particular embodiment of the method for mounting a sliding leaf 1 comprising an insulation device 12 is now described with reference to the figures 5 to 7 . This process can typically be carried out by an installer for installation of the opening at a customer's.

The method includes the supply of a profile 101' comprising the insulation device 12, and more particularly the seal according to the characteristics described above. The profile 101' is then sectioned to reduce its length along its main direction of extension x and form the upper crosspiece 101 of the opening 1. Thus, the length of the upper crosspiece 101 and that of the sealing device 12 can be adapted to the desired dimension at the place of assembly of the opening 1. The profile 101' can only include the inner sub-profile 101a and not the outer sub-profile 101b, according to the example illustrated by the figure 5 , during cutting and the outer sub-profile 101b can then be fixed by clipping. Alternatively and widely preferred, the profile 101' comprising the inner sub-profile 101a and the outer sub-profiles 101b, according to the example illustrated in figure 6 , are assembled before being cut. Once the section intended to form the upper crosspiece 101 has been sectioned, the seal 120 extends over at least 80% of the length of the upper crosspiece 101, and preferably over substantially the entire length of the upper crosspiece 101.

Following the sectioning of the profile 101' to form the upper crosspiece 101, the method comprises the assembly of the fixed frame 10 by assembling the upper crosspiece 101 comprising the seal 120, a lower crosspiece 100 and two uprights 102.

Each leaf 11 is then engondé in the opening 1 in the following way. Each leaf 11 can be presented in an inclined manner relative to the frame 10. The upper section 111 of each leaf 11 can then be inserted into the upper crosspiece 101 of the frame 10, applying pressure with each leaf 11 so as to compress the body 1202 of the seal 120. For this, according to the example illustrated in the figure 7 , the upper profile 111 of each leaf can bear against the lower face 1200 of the seal 120, via the bead 1110 and the seal 1111a. The body 1202 of the seal 120 can then be in its second compression configuration, as previously described. Each leaf can then be straightened so as to align the leaf 11 with the uprights 102 of the frame 10 in a vertical direction z. The lower profile 110 of each leaf 11 can then be introduced into the lower crosspiece 100 of the frame 10, so as to arrange each leaf 11 in its sliding position in the frame 10. The introduction of the lower profile 110 into the lower crosspiece 100 can more particularly be achieved by lowering the leaf 11. The seal 120 is thus less compressed than in its second configuration. The seal 120 can therefore be redeployed so as to be in its first compression configuration, as previously described.

Thanks to the compression of the seal 120, it is understood that the opening 1 allows the engondage of the leaves 11 without requiring the removal of the insulation device 12. The assembly of the leaves is thus facilitated compared to the solutions implementing a rigid PVC profile, these solutions requiring removal of the PVC joint before engondage and refitting of this PVC joint after engondage. The method can therefore be free of such a step of removing the insulation device 12, and more particularly the seal 120.

In view of the preceding description, it clearly appears that the invention proposes a solution making it possible to obtain good thermal insulation, or even improved insulation, while facilitating the manufacture and assembly of a sliding leaf. The invention also proposes a solution making it possible to obtain good thermal insulation, or even improved insulation, with a longer lifespan than the existing solutions.

The invention is not limited to the embodiments previously described and extends to all the embodiments covered by the claims.

In particular, provision may be made for the sliding leaf 1 to comprise two leaves 11, only one of the leaves 11 being able to slide and the other then being fixed with respect to the leaf 1. Alternatively, the leaf 1 may comprise a single leaf 11 sliding, the opening being for example configured so that the leaf disappears into the wall 2 on which the opening 1 is mounted. This is the case in the joinery with brick partition in particular.

The sealing device is preferably only mounted on the upper crosspiece 101 of the opening. The lower crosspiece 100 receiving water, for example from rainwater, a seal 120 comprising a foam body 1202 would not be optimal for the drainage and therefore the evacuation of the opening 1.
