Description

TECHNICAL FIELD OF THE INVENTION

[0001] The present invention relates to the field of sliding openings. Its application is particularly advantageous in the field of building construction, and especially for sliding doors or windows. STATE OF THE ART

[0002] Generally, a sliding door comprises a fixed frame, attached to a building wall, and at least two sliding sashes relative to the frame. The fixed frame is arranged in a substantially vertical plane when the door is in the raised position and has profiles forming the upper and lower rails, and two uprights extending vertically from the lower rail to the upper rail. These profiles define an internal space in which the sashes are hinged so as to be positioned on the tracks of the frame.

[0003] Most of these openings are located at the interface between the exterior and interior of a building. Therefore, the profiles of the fixed frame have an interior section facing the interior of the building and an exterior section facing the exterior. Because these profiles are metallic, particularly aluminum, a thermal bridge can exist between their interior and exterior sections. To provide at least some thermal insulation between the interior and exterior sections of the profile, a thermal insulation device is inserted, specifically at the top rail.

[0004] The solution generally used is the insertion of a thermal insulation device comprising two rigid profiles, usually made of extruded polyvinyl chloride (PVC), also known as rigid PVC, aligned with each other and connected at the center of the upper rail by an intermediate joining piece whose function is to contribute to the sealing in the area in which the ends of two leaves are opposite each other when the opening is in the closed position.

[0005] During the installation of the opening, the sashes are generally fitted into the frame by presenting each sash at an angle to the frame and inserting one of the sash's upper profiles into the frame's top rail. The sash is then straightened to align with the frame's uprights and positioned on the track of the frame's bottom rail.

[0006] Because the profiles of the thermal insulation system are rigid, they must be removed from the top rail during the sash installation stage. The intermediate connecting piece is also removed. Once the sashes are inserted into the frame, the installer then repositions the profiles along with the intermediate connecting piece. This solution is relatively time-consuming and complex to implement, and it is costly. Furthermore, this type of solution offers poor thermal and wind insulation performance.

[0007] Furthermore, over time, the sashes sometimes rub against the profiles of the thermal insulation system, hindering their smooth sliding within the opening. This can be caused, for example, by a lack of parallelism created during the installation of the sash, and / or by the aging of the sash, or even the building itself. To limit this friction, professionals often remove the PVC profiles. This significantly degrades the thermal insulation performance.

[0008] Other solutions have been considered, including the integration of foam elements. However, in practice, the lifespan and performance of these solutions have proven very limited. This lack of reliability has prevented them from gaining traction on the market.

[0009] FR3043121 A1, FR2922249A1 and KR101382560B1 disclose sliding openings.

[0010] One object of the present invention is therefore to provide a solution for achieving good, or even improved, thermal insulation, while facilitating the manufacture and installation of a sliding door. A further, non-limiting objective of the invention may be to achieve good, or even improved, thermal insulation with a longer lifespan than existing solutions.

[0011] The other objects, features, and advantages of the present invention will become apparent from an examination of the following description and accompanying drawings. It is understood that other advantages may be incorporated. SUMMARY OF THE INVENTION

[0012] To achieve this objective, according to a first aspect of the invention, a sliding opening according to claim 1 is provided, comprising: a fixed frame, the frame comprising a lower rail, an upper rail, the lower rail and the upper rail each extending in a horizontal direction x, and two uprights arranged opposite each other and each extending in a vertical direction z from the lower rail to the upper rail, at least one sash mounted to slide in the frame in a sliding direction parallel to the horizontal direction x, the at least one sash comprising a lower profile configured to cooperate with the lower rail, preferably, the lower profile is configured to slide on a rail of the lower rail, for example by means of at least one carriage carried by one between the frame and the sash, and an upper profile configured to cooperate with the upper rail, for example by being guided in sliding by the upper rail, an insulation device fixed on the upper rail.

[0013] The insulation system includes a sealing gasket mounted on the upper cross member, the sealing gasket: having an upper face, extending over at least 80% of the length of the upper rail, the length of the upper rail being taken along the horizontal direction x or equivalently, along the sliding direction of at least one leaf, and comprising a body of deformable foam, preferably 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 under face for the sealing gasket.

[0014] The insulation device is further configured so that the upper profile of at least one leaf is, over at least 80% of the length of at least one leaf, in contact with the lower face of the sealing gasket, regardless of the position of the leaf when it slides in the frame.

[0015] When a sash slides into the opening, each upper sash profile comes into contact with the sealing gasket and rubs against the film. Thus, this opening provides a seal along at least each upper sash profile. Furthermore, during the development of the present invention, it was found that this insulation device surprisingly exhibits very good robustness, particularly resistance to pull-out during sash handling, and therefore a longer lifespan compared to existing solutions.

[0016] This window / door offers particularly high thermal insulation performance. It can also provide remarkable air, water, and wind tightness (AEV tightness).

[0017] This opening mechanism features continuous weatherproofing, meaning a continuous seal across at least 80% of the top rail. This solution differs radically from existing solutions that use a central piece to join two profiles of a PVC seal, or an intermediate joining piece whose function is to contribute locally to weatherproofing in the area where the ends of two sashes meet when the opening is closed.

[0018] Furthermore, this opening mechanism allows for significantly easier manufacturing and installation compared to existing solutions. In particular, it minimizes the number of parts required for sealing, thus reducing the complexity and cost of the opening. In addition, this opening allows the sashes to be hinged into the frame without having to remove the insulation, and more specifically the weatherstripping and the intermediate connecting piece.

[0019] The sealing gasket can be mounted on the top rail by fixing, preferably by gluing, its upper surface directly to the rail. Alternatively, the sealing gasket can be mounted on the top rail using an additional component, such as an intermediate profile, designed to accommodate the sealing gasket and to be fixed, for example, by clipping it onto the top rail. It is therefore understood that the mounting of the sealing gasket on the top rail can be direct, between the gasket and the top rail, or indirect, via this additional component.

[0020] A second aspect of the invention relates to a method of manufacturing a profile intended to form an upper crossbar of a sliding opening according to claim 11, comprising the fixing of an insulation device on a profile, said fixing comprising the mounting of a sealing gasket on the profile, the sealing gasket comprising a body of deformable foam, preferably 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 a lower face for the sealing gasket.

[0021] Pre-fitting the sealing gasket to the profile, before any cutting of the profile and gasket, allows the assembly formed by the profile and gasket, possibly supplemented by an intermediate profile, to be manufactured in a standard factory format. For example, assemblies of 6.5 linear meters can be produced. The manufacturing process for the profile used to form the top rail is thus simplified, and its cost is reduced.

[0022] A third aspect of the invention relates to a method for mounting a sliding opening according to claim 13, comprising: the supply of a profile intended to form a top rail including an insulation device fixed to the profile, the insulation device including a sealing gasket, the sealing gasket including a body made of deformable foam, preferably 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 sealing gasket, the cutting of the profile to reduce the length of the profile so as to form at least one top rail of the opening, and preferably several top rails, the sealing gasket extending over at least 80% of the length of the top rail, the assembly of a fixed frame by joining the top rail, a bottom rail and two stiles, the fitting of at least one sash into the frame,The hinge installation comprises: the insertion of at least one leaf into the upper rail, presenting the leaf at an angle relative to the frame and compressing the body of the sealing gasket with the leaf; then the insertion of at least one leaf into the lower rail, so as to position the leaf in a sliding position within the frame, the upper profile of the leaf being in contact, in the sliding position, with the lower face of the sealing gasket.

[0023] According to one example, the upper profile of at least one leaf is, over at least 80% of the length of at least one leaf, in contact, in the sliding position, with the lower face of the sealing gasket regardless of the position of the leaf when it slides in the frame.

[0024] This process allows the opening to be mounted according to the previously stated characteristics.

[0025] If the sealing gasket is glued into the upper crossbar, this gluing step is preferably carried out before delivery to the company that performs the assembly and installation of the opening frame.

[0026] If the weatherstripping is bonded to the intermediate profile, the latter can be attached to the top rail before delivery to the company that assembles and installs the window frame. Alternatively, the intermediate profile can be attached to the top rail by the company that assembles and installs the window frame.

[0027] Thanks to the cutting of the profile used to form the top rail, the dimensions of the top rail and its sealing gasket can be determined in the workshop of the team installing the window or door, or even on-site. This dimensioning can therefore be customized by the window or door manufacturer or installer. The process thus results in increased productivity during window and door manufacturing. BRIEF DESCRIPTION OF THE FIGURES

[0028] The aims, objects, characteristics and advantages of the various aspects of the invention will become clearer from the detailed description of one embodiment thereof, illustrated by the following accompanying drawings in which: There figure 1 illustrates an overview of a sliding door according to an embodiment of the invention, with the leaves in a closed position. figure 2illustrates a longitudinal cross-sectional and top view of the sliding door according to one embodiment of the invention. figure 3 illustrates a cross-sectional view of an upper portion of the sliding door according to one embodiment of the invention. figure 4 illustrates a longitudinal and side cross-sectional view of the upper part of the sliding opening, according to section AA shown in figure 3 .

[0029] The drawings are provided by way of example and are not intended to limit the scope of the invention. They are schematic representations of the principle intended to facilitate understanding of the invention and are not necessarily to scale with practical applications. In particular, the number of leaves, as well as the relative dimensions of the sealing device and the top rail, are not necessarily representative of reality. DETAILED DESCRIPTION OF THE INVENTION

[0030] Before beginning a detailed review of embodiments of the first aspect of the invention, optional features that may possibly be used in association or alternatively are stated below.

[0031] In one example, the foam body is elastically deformable. Specifically, the foam can deform to allow the sash to be fitted into the frame during installation, while at least partially returning to its initial position to ensure contact between the weatherstripping and the sash as the latter slides within the frame. In another example, the foam body is deformable and has shape memory. Alternatively, the foam body can be deformable without having shape memory.

[0032] For example, the sealing gasket extends along the entire length of the top rail. This ensures a continuous seal along the entire length of the top rail. The thermal insulation system can also consist solely of the sealing gasket. This allows for improved insulation performance of the sash at a lower cost and with even easier installation.

[0033] In one example, the body of the sealing gasket is configured to have a first compression configuration in which the foam body is compressed, at least vertically above the top profile of at least one sash, regardless of the position of at least one sash when it slides within the frame. In another example, the body of the sealing gasket is configured to have a second compression configuration in which the foam body is compressed, at least vertically above the top profile of at least one sash, when at least one sash is engaged in the opening, the second configuration being more compressed than the first configuration.

[0034] In one example, the body of the sealing gasket has a maximum compression configuration in which the body of the sealing gasket is compressed to at least 40%, and preferably to at least 60%, and preferably to at least 80% of its thickness when the body of the sealing gasket is uncompressed. In this description, the thickness of the sealing gasket is taken in the vertical direction z. In another example, the body of the sealing gasket has compressibility such that, under a manual locking force applied to at least one leaf by two operators, the body of the sealing gasket is compressed to more than 40%, preferably more than 60%, and preferably to 80% of its thickness when the body of the sealing gasket is uncompressed.

[0035] Preferably, the body of the seal is made of a low-density shape-memory foam, and more preferably with a density less than 35 kg / m³, preferably less than 30 kg / m³, and preferably between 25 and 29 kg / m³. As an example, the film has a hardness lower than that of extruded polyvinyl chloride. Typically, this hardness is Shore D. Preferably, the film can be deformed by pressure applied by a user's finger.

[0036] According to one example, the film has a lower coefficient of friction than extruded polyvinyl chloride.

[0037] For example, the film has a tensile strength greater than 20 MPa, preferably greater than 25 MPa. This minimizes, or even eliminates, the risk of tearing the film during the installation of the opening and / or during the sliding of the sash(es).

[0038] According to one example, the film is based on polytetrafluoroethylene or its derivatives, abbreviated PTFE hereafter.

[0039] According to one example, the film is based on polyethylene terephthalate or its derivatives, abbreviated PET hereafter.

[0040] In one example, the sealing gasket is free of extruded polyvinyl chloride. According to the present invention, the body of the sealing gasket has, in its cross-section, two sides separated by a lower face. The lower face is directed towards the ground. The film covers substantially the entire lower face of the body. It does not extend over the two sides, the film thus covering only the lower face of the sealing gasket body.

[0041] According to the present invention, the body of the sealing gasket and the film form a single-piece assembly, preferably the body of the sealing gasket and the film do not have any discontinuity over the extension length of the sealing gasket on the upper cross member.

[0042] In one example, the upper rail has at least two guide rails for at least one leaf, said rails being parallel and extending mainly in the sliding direction of 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.

[0043] As an example, the insulation device may include an intermediate profile forming a groove defined by a bottom and two side walls, the upper face of the sealing gasket being fixed, and preferably bonded, to the bottom of the groove. The intermediate profile may be designed to be fixed, for example by clipping, into the groove of the upper cross member.

[0044] Thus, the intermediate profile forms a stretcher that supports the sealing gasket. Preferably, the intermediate profile has a U-shaped cross-section. The bottom of the U defines the bottom of the groove.

[0045] This embodiment has the advantage of considerably reducing the constraints on fixing the sealing gasket. Indeed, for a bond to be effective, especially in the long term, it must take place in a rigorously controlled environment, particularly in terms of temperature, humidity, and levels of particles such as dust. A frame assembly workshop, which is typically used by companies that install these windows and doors at the end customer's premises, is neither designed nor capable of guaranteeing this rigorous environmental control. During the development of the present invention, it was observed that bonding carried out in this type of workshop leads to premature detachment of the sealing gaskets during handling of the sashes.

[0046] The proposed method, which involves inserting an intermediate piece, preferably made of PVC, into the top rail, preferably by clipping it in place, and to which the weatherstripping is bonded, avoids these problems. Indeed, bonding the weatherstripping to the intermediate piece can be carried out in a perfectly controlled environment, thus guaranteeing the effectiveness of the bond. The intermediate piece, fitted with the weatherstripping, can then be delivered to the company that assembles the frame and installs the sash. Upon delivery, the intermediate piece can already be integrated into the profile that will form the top rail. Alternatively, the intermediate piece can be delivered separately, allowing the company assembling the frame to attach it, preferably by clipping it in place, to the inside of the top rail.

[0047] Furthermore, the intermediate piece, more precisely the bottom of its groove, exhibits continuous material along its entire length. The bonding interface between the intermediate piece and the seal is therefore continuous, contributing to effective bonding. Conversely, if a foam strip is bonded directly to an upper rail, the bonding interface may exhibit discontinuities at the interface between the two profiles, creating a thermal break. During the development of the present invention, it was observed that this discontinuity in the interface often increases the risk of the seal being torn off, thus reducing the lifespan of the opening.

[0048] Furthermore, this design significantly simplifies maintenance and after-sales service for such a window or door. Indeed, if the seal needs replacing, the operator can easily remove the intermediate piece by unclipping it from the upper rail and then replace it with another intermediate piece equipped with a suitable seal.

[0049] According to one example, each side wall of the intermediate profile has an inner face in contact with or facing a flank of the sealing joint and an outer face, opposite the inner face, the outer face having at least one relief configured to cooperate with a relief of the upper cross member so as to allow the intermediate profile to be clipped onto the upper cross member.

[0050] In one example, the top rail has at least two guide rails for at least one door leaf, these rails being parallel and extending in the sliding direction of the door leaf. At least one groove may be located between these rails, this groove being further defined by a bottom and two side walls. The upper surface of the seal may 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 of a rail.

[0051] In one example, the sealing gasket extends transversely from one side wall to the other of the two side walls of at least one groove. The sealing gasket can extend over at least 90%, and preferably at least 95%, of the distance between each side wall, the distance between each side wall being taken along a y-direction perpendicular to the horizontal x-direction. Synergistically, with the relative dimensions of the gasket body and the film, the sealing gasket thus perfectly fills the groove, ensuring optimal sealing of the sash at its upper rail.

[0052] Optional features of the second aspect of the invention are set out below, which may possibly be used in association or alternatively.

[0053] According to one example, the assembly of the sealing joint includes gluing one upper face of the sealing joint onto an intermediate profile, then fixing, for example by clipping, the intermediate profile onto the profile intended to form the upper cross member.

[0054] In one example, the sealing gasket is installed by bonding its upper surface to the profile that will form the upper cross member. In another example, the sealing gasket is installed so that it extends along the entire length of the profile that will form the upper cross member.

[0055] Optional features of the third aspect of the invention are set out below, which may possibly be used in association or alternatively.

[0056] As an example, the sash assembly process eliminates the need to remove the weatherstripping between frame assembly and the hinge placement of at least one sash within the frame. This simplifies sash assembly and reduces the sash's manufacturing cost. Furthermore, the risk of weatherstripping damage is minimized or even eliminated, improving the sash's lifespan. The risk of reduced thermal insulation performance is also limited or eliminated. In another example, during the hinge placement of at least one sash, the compression of the weatherstripping body by the sash is performed manually by an operator. In the following description, terms such as "vertical," "longitudinal," "transverse," "upper," "lower," "front," "rear," "above," and "below" will be used.These terms should be interpreted in relation to the normal operating position of the sliding door. For example, if the door is intended to be fixed vertically to a wall, the upper faces of the door elements correspond to the faces of the elements that are facing upwards. In the following, reference is made to the case where the normal operating position of the door is vertical.

[0057] The term "monobloc assembly" means an assembly that is a single piece, or equivalently forms a block.

[0058] Extruded PVC, or rigid PVC, refers to polyvinyl chloride or one of its derivatives used to manufacture profiles and tubes by extrusion. Rigid PVC is distinct from flexible PVC, also called plasticized PVC, and from expanded PVC. A parameter "approximately equal to / greater than / less than" a given value means that this parameter is equal to / greater than / less than the given value, within a margin of error of ±10%, or even ±5%, of that value.

[0059] An element "based" on a material A is understood to be an element comprising that material A and possibly other materials, for example additives.

[0060] The sliding opening 1 is now described with reference to figures 1 to 4 As illustrated in figure 1The sliding door 1 comprises a fixed frame 10, attached to a wall 2, for example, of a building. The fixed frame 10 is preferably arranged in a substantially vertical plane when the door 1 is in the raised position. The frame 10 comprises profiles forming a lower rail 100 and an upper rail 101, each of the rails 100, 101 extending in a horizontal direction x. The frame 10 further comprises two uprights 202, each extending in a direction

[0061] vertical z, from the lower cross member 100 to the upper cross member 101. The sliding opening 1 includes at least one leaf 11 configured to slide along the horizontal direction x, or equivalently along the main extension direction of the cross members 100, 101. In the following, it is considered, without limitation, that the sliding opening 1 includes two sliding leaves.

[0062] 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 sash 1, passing through a plurality of sash 1 opening positions. For this purpose, each leaf 11 includes a lower profile 110 configured to cooperate with the lower rail 100 of the frame 10. For example, the lower profile 110 can be configured to slide on a rail of the lower rail 110, for instance, via a roller carriage supported by one of the frame and the leaf, the roller carriage comprising at least one roller. Furthermore, each leaf 11 includes an upper profile 111 configured to cooperate with the upper rail 101. For example, the upper profile 111 is guided in its sliding motion by the upper rail 101.

[0063] Each leaf may also include a central mullion 113, as well as a peripheral mullion 114. The closed position of the leaf is now described in the example illustrated in figure 2 When the leaf 11 is in the closed position, the peripheral mullion 114 of each leaf can be brought against a mullion 102 of the frame. Furthermore, the central mullions 113 of the two leaves are positioned at least partially opposite each other along a transverse direction y. The central mullions 113 are configured to cooperate in order to ensure a certain degree of sealing. To this end, the central mullions 113 may be provided with additional ridges that ensure the leaves engage to provide a sliding stop and contact with the sealing gaskets. These ridges are illustrated in figure 2 in the form of a chicane 13.

[0064] Each leaf 11 can slide along the horizontal direction x between the closed position and the fully open position of the opening 1, in which the central mullion 113 of the leaf can come to rest against a mullion 102 of the frame 10.

[0065] In order to position each leaf 11 in a sliding position during the hinged operation of the leaves, described in more detail later, the upper rail 101 includes a groove 1011, as illustrated in figure 3Since this groove 1011 can be the site of heat transfer on either side of the opening 1, the opening 1 also includes a thermal insulation device 12, inserted at the level of the upper rail 101, and more specifically in this groove 1011. This sealing device 12 is configured to provide at least thermal insulation on either side of the opening 1 along the length of the upper rail 101. This length is taken along the horizontal direction x, or equivalently along the sliding direction of the sashes 11. This device 12 can also ensure AEV sealing, and in particular against air and wind.

[0066] To this end, the device 12 includes a sealing gasket 120 extending over at least 80% of the length of the upper cross member 101. The greater the extension length of the sealing gasket 120, the shorter the length of any potential thermal bridge at the upper cross member, along the horizontal direction x. Preferably, the sealing gasket 120 extends substantially over the entire length of the upper cross member 101, as illustrated in figure 2 . Thus, the seal can be continuous over the entire length of the upper cross member 101, and more particularly from one upright 102 to the other upright 102 of the opening 1.

[0067] Furthermore, according to a preferred embodiment, the seal 120 has no discontinuities along the horizontal x direction. The insulation device 12 may, in particular, comprise a single sealing gasket 120. The sash 1 is thus free of a central piece serving as a junction between a plurality of sealing gaskets 120. The insulation device 12 therefore comprises a reduced number of parts required to achieve insulation, or even only one part. The complexity and cost of the sash 1 are thus reduced, while maintaining good thermal insulation performance.

[0068] The 120 sealing gasket is now described in more detail with reference to figures 3 , 8 And 9A According to one example, the sealing gasket 120 has an upper face 1201 fixed to the upper cross member 101, as illustrated for example in figure 3Preferably, the upper face 1201 of the sealing gasket 120 is glued to the upper cross member 101, ensuring a more robust fixing of the gasket 120 than a simple clipping of the gasket 120 into the cross member 101.

[0069] Preferably, according to another example illustrated by the figures 8 And 9AThe sealing device 12 may include an intermediate profile 121, configured to accommodate at least part of the sealing gasket 120, and to be fixed, for example by clipping, to the upper rail 101. The intermediate profile allows good control of the interface between the upper rail 101 and the profile 101. In addition, this makes it possible to avoid gluing the sealing gasket 120 on the manufacturing or installation site of the joinery, as described in more detail later. For this purpose, the intermediate profile 121 is preferably a U-shaped piece. It thus forms a stretcher for the sealing gasket 12. Preferably, the sealing gasket 120 is bonded to the profile 121. Securing the sealing gasket 120 to the intermediate profile 121, the latter being mounted on the upper cross member 101, allows for more reliable fastening and greater robustness of the sealing device 12.

[0070] Furthermore, the sealing gasket 120 is configured so that the upper profile 111 of each leaf 11 is in contact with the lower face 1200 of the sealing gasket 120 for at least 80% of its length, and preferably for substantially its entire length, this length being measured in the horizontal direction x. Thus, this configuration ensures optimal thermal insulation by leaving no gap between the upper rail 101 and the upper profile 111 of each leaf 11. Since the sealing gasket 120 extends over at least 80% of the length of the upper rail 101, this insulation can be achieved regardless of the position of each leaf 11 as it slides within the frame 10.

[0071] To allow the sashes 11 to be fitted into the groove 1011 while ensuring optimal and continuous insulation along the upper rail 101, the seal 120 includes a body 1202 made of deformable foam. The body 1202 is made of deformable foam so as to allow the sash 11 to be fitted into the frame 10 during the installation of the opening sash 1, while also ensuring contact between the sealing gasket 120 and the sash 11 as the latter slides within the frame 10. Preferably, the foam of the body 1202 has shape memory, so that once the foam body 1202 is deformed, the body 1202 of the sealing gasket 120 tends to redeploy either to a maximum permissible deployment configuration or to its initial configuration.

[0072] Preferably, the opening 1 is configured so that the body 1202 of the sealing gasket 120 has a first and a second compression configuration. In the first compression configuration, the foam body 1202 can be compressed at least vertically to the upper profile 111 of each sash 11, when the sash 11 is in a sliding position within the opening 1. This configuration can be illustrated by the figure 3Indeed, since the body 1202 of the seal 120 is made of foam, the seal 120 can be compressed against the upper profile 111 of each leaf 11, even in the event of slight variations in the distance between the upper rail 101 and the upper profile 111 of each leaf. Thus, thermal insulation can be maintained despite manufacturing tolerances and despite the aging of the sash 1, or even the building, which may cause slight deflection or sagging. Furthermore, these variations allow for maintaining a good seal of the sash after adjusting its height, an adjustment often necessary to correct any unevenness in the frame.

[0073] In the first compression configuration, the foam body 1202 can be compressed vertically against the upper profile 111 of each leaf 11, across a range of leaf positions, 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 sealing gasket 120, and thus ensuring a good seal of the opening.

[0074] THE Figures 9A , 9B And 9C The diagram illustrates, as an example, a leaf 11 in its nominal, low, and high positions. The compression of the sealing gasket can be adjusted according to the position of the leaf 11, allowing for adjustment of the parallelism of the leaves within the frame. This adjustment is made, for example, using adjusting screws on the leaf support rollers on the frame rails.

[0075] According to an example in which the sealing gasket has a height along the z-direction of approximately 17 mm, in the nominal position of the leaf 11 figure 9A The seal 120 is compressed by the leaf 11 over a distance D4 of approximately 2 to 2.5 mm. In the lowered position of the leaf 11... figure 9B The seal 120 can be compressed by the leaf 11 over a distance D5 of approximately 0.5 to 1 mm. In the upper position of the leaf 11... figure 9B , the seal 120 can be compressed by the leaf 11 over a distance D6 of approximately 5 to 5.5 mm.

[0076] During the development of the present invention, it was observed that in each of these positions, the sealing is particularly effective and the seal 120 remains particularly effective even after numerous opening and closing cycles of the leaves. In particular, even in the most compressed position, the seal 12 does not detach from the upper cross member 101 thanks to the means used to reduce friction, which will be detailed below.

[0077] In the second compression configuration, the foam body 1202 can be compressed, at least vertically above the upper profile 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 7The second compression configuration allows each leaf 11 to be fitted into the opening 1, as described later. Thus, when each leaf 11 is fitted, the foam body 1202 of the seal can be compressed with a limited, or even zero, risk of breakage or rupture.

[0078] Preferably, the foam body 1202 has a maximum compression configuration, in which the body 1202 is compressed to at least 40%, preferably at least 60% and preferably at least 80% of its thickness when the sealing gasket is uncompressed, this thickness being taken along 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<.

[0079] In the sliding position of each leaf 11, the sealing gasket 120 includes a film 1203 configured to minimize friction between the sealing gasket and the upper profile 111. The film 1203 also has a lower coefficient of friction than the foam of the body 1202. For this reason, the film 1203 forms the lower face 1200 of the sealing gasket 120. The film can extend substantially over the entire contact surface between the gasket 120 and the upper profile 111, and preferably over the entire lower face 1202b of the foam body 1202. When each leaf 11 slides along 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 insulation device 12. Preferably, the film 1203 also has a lower coefficient of friction than extruded PVC.More preferably, the 1203 film 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.

[0080] The 1203 film may also have tear-resistant properties to minimize, or even prevent, snagging and / or tearing of the 1203 film when each sash slides in the horizontal direction x within the opening 1. More specifically, the 1203 film may have a tensile strength significantly greater than 20 MPa, and preferably significantly greater than 25 MPa. The 1203 film thus exhibits tensile strength properties superior to those of extruded PVC, which has a tensile strength of approximately 8 MPa.

[0081] 1203 film may have a lower hardness than extruded PVC. Typically, 1203 film is made from a material with a Shore D hardness lower than that of extruded PVC. For example, 1203 film may be made from a material with a Shore D hardness significantly lower than 70, such as PTFE.

[0082] Even more preferably, the film is deformable by pressure exerted by an operator's finger. Synergistically, with the compression capacity of the body 1202 of the sealing gasket 120, the previously stated characteristics of the film 1203 allow for effortless compression of the sealing gasket 120, while limiting the risk of damage to the gasket 120 during the installation of the opening sash 1 and during the sliding of the sashes. In another example, the film is rigid; preferably, the film is non-deformable by pressure exerted by an operator's finger. In this example, the film is a PET film.

[0083] The 1203 film can be, more specifically, a PTFE film, as this type of film offers excellent tear resistance, low deformation, and a low coefficient of friction. Alternatively, the 1203 film can be a PET film, as this offers a good compromise between tear resistance and a low coefficient of friction, is more rigid than PTFE, and is less expensive. Preferably, the 1203 film has a thickness of approximately 300 µm.

[0084] According to the present invention, the body 1202 of the seal 120 and the film 1203 form a single-piece assembly. Preferably, the body 1202 and the film 1203 are continuous along the entire extension length of the sealing gasket 120 on the upper cross member 101. This limits the risk of separation of the body 1202 and the film 1203. Furthermore, the film 1203 may not extend beyond the flanks 1202a of the body 1202 of the seal 120, along the transverse direction y. These characteristics further limit the creation of potential snag points that could lead to deterioration of the sealing gasket 120 during the installation of the opening and during the sliding of the sashes 11. According to the present invention, the film 1203 does not extend onto the sides 1202a of the body 1202 of the gasket 120. As an example, the body 1202 and the film 1203 can be formed as a multilayer assembly in an extruder.

[0085] By way of illustration, a more detailed example of the upper part of opening 1 is now described with reference to Figures 1 And 3 .

[0086] According to this example, the top rail 101 may include an inner sub-profile 101a extending along the horizontal x-direction between the two jambs 102 of the sash 1. The inner sub-profile 101a can be attached, for example by clipping, to one or more outer sub-profiles 101b to form the top rail 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 sandwiched between the outer sub-profiles 101b. The inner sub-profile 101a thus acts as a thermal break profile, and the outer sub-profiles 101b define the outer and inner profiles of the top rail 111.

[0087] The upper cross member 101 may further comprise two parallel rails 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 figure 3 The assembly of the inner sub-profile 101a with the outer sub-profile 101b presents a projection along 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.

[0088] According to this example, the opening 1 comprises two leaves 11 whose upper profiles 111 are configured to slide along the rails 1010 in a horizontal direction x. This sliding is ensured by rollers mounted for rotation on the upper profile 111 and which roll on the rails 1010. For clarity, the rollers are not shown in the figures.

[0089] Each upper profile 111 includes a glazing bead 1110. The glazing bead 1110 can be fixed to a support profile 1111, for example by clipping it into place. It rests on the glazing 112, preferably via a gasket 1112a mounted on the glazing 112. The gasket 1112a can, in particular, be configured to enclose the glazing 112 around a spacer 1120.

[0090] The support profile 1111 can also carry seals 1111a, one end 1111b of each of these seals 1111a coming into contact with the upper cross member 101, in order to ensure a seal during sliding.

[0091] The distance D1 between the rails 1010 and the dimensions of the upper profile 111 of each leaf 11 can be chosen so that the upper profiles 111 are separated by a distance D2 along the transverse direction y.

[0092] According to this example, the two rails 1010 are further separated by a distance D1 along a direction parallel to the transverse direction y. The upper sleeper 101 thus comprises a groove 1011 having a bottom 1011a and side walls 1011b, the side walls being formed by the two rails 1010.

[0093] The sealing gasket 120 can be positioned in the groove 1011. The upper face 1201 of the gasket 120 can be fixed, and preferably glued, to the bottom 1011a of the groove 1011. The upper face 1201 of the sealing gasket 120 is thus in contact with the bottom 1011a of the groove 1011 along the entire length of the upper cross member 101, this length being taken in the horizontal direction x, as illustrated in figure 4Advantageously, the bottom 1011a of the groove 1011 is continuous. Preferably, it is flat and without discontinuities, preferably along the entire length of the upper cross member 101. The interface between the sealing gasket 120 and the upper cross member 101 is thus continuous, promoting effective bonding. The sealing gasket 120 can also extend in the transverse direction y, from one side wall 1011a to the other of the groove 1011. In particular, the sealing gasket 120 can extend over at least 90%, and preferably at least 95%, of the distance D1 between the two side walls 1011a. Thus, the upper cross member 101 facilitates the positioning of the sealing gasket 120 and helps to hold it in place, and the gasket 120 ensures sufficient sealing.With the sealing gasket 120 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 gasket 120 are protected by the upper cross member 101 during the installation of the opening 1 and during its use. Furthermore, the width of the sealing gasket 120, measured along the transverse direction y, can be substantially equal to the width of the groove 1011 along its cross-section, within the installation tolerances.

[0094] As illustrated by the figures 8 And 9AThe sealing gasket 120 can be positioned in the intermediate profile 121, which forms a groove 1210. The upper face 1201 of the gasket 120 can be fixed, and preferably bonded, to the bottom 1210a of the groove 1210a. Since the sealing gasket 120 is housed in the groove 1210 between the bottom 1210a and the two side walls 1210b, the sides 1202a and the upper face 1201 of the gasket 120 are protected by the intermediate profile 121 during the installation of the opening 1 and during its use. Furthermore, the width of the sealing gasket 120, measured along the transverse direction y, can be substantially equal to the width of the groove 1210 along its cross-section, within the installation tolerances. In one embodiment, the sides 1202a and the upper face 1201 of the seal 120 are bonded to the side walls 1210b of the intermediate profile. In one example, the intermediate profile 121 is an extruded PVC profile.

[0095] The insulation device 12, i.e., the assembly formed by the sealing gasket 120 and the intermediate profile 121, can be positioned in the groove 1011 of the upper cross member 101. For example, the intermediate profile 121 is clipped into the groove 1011. This ensures a simple, quick, and controlled fixing of the intermediate profile in the cross member 101. To achieve this, the intermediate profile 121 can have ridges 1210ba that complement the ridges of the upper cross member 101. Preferably, the ridges 1210ba are supported and formed by an outer face of each of the walls 1210b, with the inner face of each of the walls 1210b facing the sealing gasket 120.

[0096] In one example, each internal wall is in contact with a flank 1202a of the sealing joint 120. In another example, each internal wall is bonded to the flank 1202a of the sealing joint 120. Alternatively, the internal wall is not bonded to the flank 1202a of the sealing joint 120.

[0097] The sealing gasket 120, the intermediate profile 121 and the upper cross member 101 can be configured so that the sealing gasket 120 extends over at least 90%, and preferably over at least 95%, of the distance between the two side walls 1011a of the groove 1011 of the upper cross member 101, to ensure sufficient sealing.

[0098] In the sliding position of the leaves 11, the sealing gasket 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 3For each upper profile 111, the sliding guide 111a, bearing against the side wall of the rail 1010, corresponding to the side wall 1011b of the groove 1011, may also bear against the lower face 1200 formed by the film 1203, so as to compress the sealing gasket 120. A portion of the glazing bead 1110 positioned opposite the groove 1011 may also bear against the lower face 1200 formed by the film 1203, so as to compress the sealing gasket 120. The lower face 1200 of the sealing gasket 120 may be in contact with the glazing bead 1110 along the entire length of the upper profile 111, this length being taken in the horizontal direction x, as illustrated in figure 4 .

[0099] Furthermore, the relative dimensions of the upper profile 111 of each leaf and of the upper rail 101 can be chosen so that a portion of the lower face 1200 of the sealing gasket 120 is not in contact with the upper profiles 111. As illustrated in figure 3 The lower face 1200 of the seal 120 is not in contact with the upper profiles 111 over a distance D3, taken along the transverse direction y, inducing the formation of a protrusion of the seal 120 between the two upper profiles 111. Thus, the sealing of the device 12 is further improved. A particular embodiment of the manufacturing process for a profile 101' intended to form at least one upper rail 101 of a sliding door 1, for example after cutting by an installer for fitting the door, and comprising an insulation device 12, is now described with reference to figures 5 and 6The profile 101' intended to form at least one upper cross member 101, is hereinafter referred to as profile 101'.

[0100] This process, typically carried out in the factory by the manufacturer of profile 101', involves supplying a first profile. This profile can typically be of a standard factory length, for example 6.5 linear meters, along its principal extension direction x. As illustrated in the figure 5This profile can be the inner sub-profile 101a, having a groove 1011 delimited by a bottom 1011a and side walls 1011b. This method further includes mounting a sealing gasket 120, according to the characteristics described above, on this profile. The profile 101' can also include an outer sub-profile 101b fixed to the inner sub-profile 101a, for example by snap-fitting. Alternatively, the sealing gasket can be mounted on the assembly formed by the inner sub-profile 101a and the outer sub-profile 101b. Preferably, the sealing gasket 120 is mounted along the entire length of the profile 101'.

[0101] As an example, the sealing gasket 120 can be fixed, and preferably bonded, by its upper face 1201 to the bottom 1011a of the groove 1011 to form the profile 101'. For example, the sealing gasket 120 can be bonded to the inner sub-profile 101a at the factory after powder coating or at the factory using an extruder. For example, the sealing gasket 120 can be supplied in roll form, unrolled, and bonded to the inner sub-profile 101a.

[0102] According to another example, the sealing gasket 120 can be fixed, and preferably glued to the intermediate profile 121 previously described, then the assembly formed by the sealing gasket 120 and the intermediate profile 121 can be fixed on the upper cross member 101, and more particularly in the groove 1011 of the upper cross member 101, to form the profile 101'.

[0103] The bonding of the sealing gasket 120 can thus be carried out independently of the manufacturing of the profile 101' or the installation of the opening. The gasket 120 can, in particular, be bonded to the intermediate profile 121 under specific humidity and temperature conditions to ensure proper bonding. The gasket 120 can, for example, be pressed into the intermediate profile 121, which has a standard factory length, for example, 6.5 linear meters, using a press. During the development of the invention, it was demonstrated that the strength of the sealing gasket 120 and the robustness of the sealing device 12 were thereby increased.

[0104] In the example illustrated in figures 9A to 9CThe upper cross member 101 comprises two profiles 101b separated by an inner profile 101a, the latter being formed by at least one, and preferably two, polyamide strips 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 the 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 the groove 1011 is not continuous. However, this does not pose a problem for the retention of the sealing gasket 120 since the latter is fixed to the upper cross member 101 via the intermediate profile 121, within which it is housed. The intermediate profile 121 is preferably clipped onto the walls 1011b supported by the external profiles 101b.

[0105] A particular embodiment of the method for mounting a sliding opening 1 comprising an insulation device 12 is now described with reference to figures 5 to 7 This process can typically be carried out by an installer for the installation of the opening at a customer's premises.

[0106] The process involves supplying a profile 101' comprising the insulation device 12, and more specifically the sealing gasket according to the characteristics described above. The profile 101' is then cut to reduce its length along its principal extension direction x and form the upper rail 101 of the sash 1. Thus, the length of the upper rail 101 and that of the sealing device 12 can be adapted to the required dimensions at the installation site of the sash 1. The profile 101' may only include the inner sub-profile 101a and not the outer sub-profile 101b, as illustrated in the example shown in the figure 5During cutting, the outer sub-profile 101b can then be attached by snapping it into place. Alternatively, and as a much preferred method, the profile 101' comprises the inner sub-profile 101a and the outer sub-profiles 101b, as illustrated in the example shown in figure 6 are assembled before being cut. Once the profile intended to form the upper cross member 101 has been cut, the sealing joint 120 extends over at least 80% of the length of the upper cross member 101, and preferably over substantially the entire length of the upper cross member 101.

[0107] Following the cutting of the profile 101' to form the upper cross member 101, the process includes the assembly of the fixed frame 10 by assembling the upper cross member 101 including the sealing joint 120, a lower cross member 100 and two uprights 102.

[0108] Each leaf 11 is then hinged into the opening 1 as follows. Each leaf 11 can be presented at an angle relative to the frame 10. The upper profile 111 of each leaf 11 can then be inserted into the upper rail 101 of the frame 10, applying pressure with each leaf 11 to compress the body 1202 of the sealing gasket 120. For this, according to the example illustrated in the figure 7The upper profile 111 of each leaf can bear against the lower face 1200 of the sealing strip 120, via the glazing bead 1110 and the sealing strip 1111a. The body 1202 of the sealing strip 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 stiles 102 of the frame 10 in a vertical direction z. The lower profile 110 of each leaf 11 can then be inserted into the lower rail 100 of the frame 10, so as to position each leaf 11 in its sliding position within the frame 10. The insertion of the lower profile 110 into the lower rail 100 can, in particular, be accomplished by lowering the leaf 11. The sealing strip 120 is thus less compressed than in its second configuration.The sealing joint 120 can therefore redeploy itself so as to be in its first compression configuration, as previously described.

[0109] Thanks to the compression of the sealing gasket 120, it is understood that the opening 1 allows the sashes 11 to be hinged without requiring the removal of the insulation device 12. The installation of the sashes is thus simplified compared to solutions using a rigid PVC profile, which require removing the PVC gasket before hinged installation and reinstalling it afterward. The process can therefore be done without this step of removing the insulation device 12, and more specifically the sealing gasket 120.

[0110] In light of the preceding description, it is clear that the invention offers a solution for achieving good, or even improved, thermal insulation, while simultaneously simplifying the manufacture and installation of a sliding door. Furthermore, the invention provides a solution for achieving good, or even improved, thermal insulation with a longer lifespan than existing solutions.

[0111] The invention is not limited to the embodiments described above and extends to all embodiments covered by the claims.

[0112] It is possible to foresee that the sliding opening 1 comprises two leaves 11, only one of the leaves 11 being able to slide and the other being fixed in relation to the opening 1. Alternatively, the opening 1 may comprise a single sliding leaf 11, the opening being configured for example so that the leaf disappears into the wall 2 on which the opening 1 is mounted. This is the case in pocket door systems in particular.

[0113] The sealing device is preferably mounted only on the upper rail 101 of the opening. Since the lower rail 100 receives water, for example from rainwater, a sealing gasket 120 with a foam body 1202 would not be optimal for drainage and therefore for the evacuation of water from the opening 1.
