Description

Title of the invention: Sliding door system and associated mounting method technical field

[0001] The present invention relates to the field of sliding door systems. Its applications include, in particular, the field of building construction and / or renovation. A particularly advantageous application concerns the installation of sliding door systems on an interface requiring good thermal insulation performance, for example, between the exterior and interior of a building. STATE OF THE ART

[0002] Generally, a pocket door system comprises a frame intended to be fixed to a wall having an opening, the wall delimiting at least part of a room in a building. The frame typically comprises a bottom rail, an top rail, the bottom and top rails each extending in a horizontal direction, and a plurality of stiles each extending in a vertical direction from the bottom rail to the top rail. The frame forms at least two spaces: a jamb opposite the wall opening and at least one pocket. The pocket door system further comprises at least one door leaf mounted to slide within the frame in a sliding direction parallel to the horizontal direction, between the pocket and the jamb. Typically, in the closed position of the pocket door system, the door leaf is arranged so as to conceal the space defined by the jamb.The door leaf can be arranged in a plurality of open positions, in which the door leaf is at least partially positioned within the retraction box.

[0003] A pocket door system can be installed on an interface wall requiring good thermal insulation performance, such as an entrance vestibule or a wall at the interface between the exterior and interior of a building. In such cases, the pocket door system includes one or more insulating panels to maintain good thermal insulation. These insulating panels are positioned within the pocket and fixed to the frame.

[0004] A covering for the pocket door system can be made following its assembly, for example by attaching an interior partition to the pocket door system, on the interior side of the room.

[0005] In order to fix an insulating panel to the frame, a commonly used solution is to fix the panel directly to the profiled frame. For this, the sliding door system is generally assembled on site piece by piece. However, the fixing of the Applying insulation directly to the frame requires multiple steps and is difficult to achieve in order to obtain good thermal insulation. It also requires experienced personnel.

[0006] There is therefore a need to facilitate the assembly of such sliding door systems.

[0007] An object of the present invention is therefore to propose a solution facilitating the assembly of a pocket door with good thermal insulation.

[0008] 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

[0009] To achieve this objective, according to one aspect, a sliding door system is planned comprising: - a frame comprising a lower crossbar, an upper crossbar, the lower and upper crossbars each extending in a horizontal direction, and a plurality of uprights each extending in a vertical direction from the lower crossbar to the upper crossbar, the frame forming a door frame and at least one thrust box, the frame having an inner face intended to be turned towards the interior of a room partially delimited by the system and an outer face intended to be turned towards the exterior of that room, - at least one sliding door leaf mounted in the frame along a sliding direction parallel to the horizontal direction, between the retraction box and the door frame, at least one door leaf comprising a lower profile configured to cooperate with the lower rail and an upper profile configured to cooperate with the upper rail, - at least one insulating panel placed in the discharge chamber, - a system for fixing the insulating panel to the frame.

[0010] Advantageously, at least one insulating panel is disposed on and / or directly above the inner and / or outer face of the frame. The fastening system comprises at least one fastening device including at least one wedge fixed to the frame and a plurality of wedge locks, each wedge lock being configured to cooperate with said wedge so as to clamp the insulating panel between said wedge and the plurality of wedge locks to support the latter, at least one wedge and the plurality of wedge locks being configured to cooperate by clipping.

[0011] Thus, the panel is mounted on the frame via the fastening device, being clamped and supported between at least one wedge and the wedge locks. The interlocking mechanism between the at least one wedge and the wedge locks supports the insulating panel. This facilitates panel mounting compared to Existing solutions that attach the panel directly to the frame offer an alternative. This solution is simpler to implement than on-site assembly, which remains complex and requires experience. Thermal insulation provided by the insulating panel is thus more efficient and consistent. Installation time is also reduced.

[0012] In order to limit the drawbacks associated with on-site assembly of existing solutions, a person skilled in the art would have sought to maximize factory assembly steps by directly attaching the insulation panel to the frame at the factory. However, this assembly method remains complex and poorly suited to industrial manufacturing. The pocket door system, according to the first aspect, therefore facilitates the assembly of the pocket door system, and in particular the mounting of the insulation panel onto the frame, while also offering a reduced manufacturing cost.

[0013] Furthermore, since the insulating panel is sandwiched between at least one wedge and the wedge locks, it is not necessary to drill through it, for example by screwing. Thermal bridges are thus reduced, and preferably eliminated, at the level of the insulating panel. The thermal insulation performance of the sliding door system is therefore improved.

[0014] A second aspect relates to a method of mounting the sliding door system according to the first aspect, comprising: - provision of the frame, - the supply of at least one insulating panel and the system for fixing the insulating panel to the frame, comprising at least one fixing device, said device comprising at least one wedge and a plurality of wedge locks, - mounting at least one insulating panel on the frame, including: • a fixing of at least one wedge of the fixing device in a frame's thrust box on at least one of the upper cross member, the lower cross member and a stile, so as to receive an insulating panel placed on and / or directly above the inner and / or outer face of the frame, • the insulating panel being placed in contact with at least one wedge, • the plurality of wedge locks of the fixing device being clipped onto at least one wedge, so as to clamp the insulating panel between said wedge and the plurality of wedge locks to support the latter.

[0015] The mounting method exhibits the effects and advantages discussed for the pocket door system according to the first aspect. The method according to this aspect and the pocket door system according to the first aspect are therefore particularly suitable for mounting on an interface wall requiring good thermal insulation performance, for example between the exterior and interior of a building.

[0032] The drawings are given by way of example and are not limiting of the invention. They constitute schematic representations of principle intended to facilitate understanding of the invention and are not necessarily to scale with practical applications. In particular, the relative dimensions of the wall and the sliding door system are not representative of reality. DETAILED DESCRIPTION

[0033] Before beginning a detailed review of embodiments of the invention, optional features which may possibly be used in association or alternatively are stated below.

[0034] According to one example, the wedge locks and at least one wedge are configured to support the insulating panel by themselves.

[0035] In one example, the insulating panel is held solely by clamping. In another example, the insulating panel is not penetrated, even partially, by a fastening means such as a screw.

[0036] According to one example, the fastening device is suitable for mounting in two orientations such that: - In a first configuration, at least one wedge is designed to be mounted on one face of a cross member and / or upright opposite the discharge box - in a second orientation, at least one wedge is configured to be mounted on a face of a cross member and / or end post not facing the discharge box, and more particularly on a face of a cross member and / or post located on the side of the inner face of the frame.

[0037] The same fixing device thus allows the insulating panel to be mounted in different positions. The installation of the sliding door system is further simplified. Production costs are also reduced. More specifically, depending on the orientation of the fixing device, the insulating panel can be positioned within the recess, flush with the frame, or projecting from the frame.

[0038] According to one example, at least one insulating panel is positioned flush with the outer face of the frame, with the fixing device mounted in the first orientation, and / or at least one insulating panel is positioned on the inner face of the frame, with the fixing device mounted in the second orientation. On the outer face of the frame, facing the outside of the room and therefore towards the wall supporting the pocket door system, the insulating panel can thus be positioned flush with the frame. This avoids creating an additional thickness against the wall, thus improving the thermal insulation provided by the pocket door system. On the inner face of the frame, the insulating panel can therefore be positioned projecting beyond the frame, which offers better thermal insulation and allows for a reduction in the dimensions of the frame profiles, thereby lowering the cost of the pocket door system.

[0039] According to one example, the pocket door system comprises a first insulating panel, called the "outer panel," positioned vertically on the outer face of the frame by at least one first fixing device, the at least one first fixing device being mounted in the first orientation. The pocket door system may comprise a second insulating panel, called the "inner panel," positioned on the inner face of the frame by minus a second fixing device, at least one second fixing device being mounted according to the second orientation. The pocket door system comprises two panels, the thermal insulation performance of the system is improved.

[0040] According to one example, at least one wedge comprises a first and a second support surface for the insulating panel, arranged substantially perpendicular to each other, each wedge lock being configured to: - in the first orientation, slide along the first support surface until the wedge lock is clipped into position on at least one wedge, the fastening device then being configured to clamp the insulating panel between the second support surface and the wedge lock, and - in the second orientation, slide on the second support surface until the wedge lock is clipped into position on at least one wedge, the fastening device then being configured to clamp the insulating panel between the first support surface and the wedge lock.

[0041] A sliding configuration until clipping allows each wedge lock to be guided onto the corresponding wedge during assembly, which is thereby facilitated.

[0042] According to one example, the system includes a fastening device on each of the upper crossbar, the lower crossbar and a stud. The support of the insulating panel is thus improved.

[0043] According to one example, at least one fastening device, and preferably each fastening device, comprises a plurality of wedges, each configured to cooperate with at least one wedge lock, preferably each wedge being configured to cooperate with a single wedge lock. A plurality of wedges per fastening device makes it possible to multiply the fastening points of the insulation panel on the frame to improve its reliability, while reducing the dimensions of each wedge. Furthermore, this allows for simplified maintenance when replacing a wedge or a wedge and wedge lock assembly.

[0044] According to one example, each wedge extends in a direction parallel to the main extension direction of the cross member or upright on which it is mounted, over a distance less than or equal to 10 cm, preferably substantially equal to 40 mm.

[0045] According to one example, at least one fastening device, and preferably each fastening device, comprises at least three wedge locks. This number of wedge locks multiplies the clamping points of the insulating panel on at least one wedge to ensure its reliable retention.

[0046] According to one example, the wedge locks, and preferably the wedge and wedge lock assemblies of at least one fastening device, and preferably each fastening device, are separated by a distance substantially less than or equal to 400 mm, preferably the distance is substantially equal to 300 mm, in a direction substantially parallel to the main extension direction of the frame profile on which at least one fixing device is mounted.

[0047] According to one example, at least one wedge comprises at least one positioning lug configured to cooperate with a complementary housing formed in the frame. The cooperation of the positioning lug and the housing allows for the positioning, and preferably the holding in position, of said wedge on the frame. Thus, the positioning of at least one wedge on the frame is facilitated and made more precise. The wedge can, in fact, be placed without having to resort to complex alignment steps. The assembly of the sliding door system is facilitated and made more reproducible.

[0048] According to one example, at least one wedge is configured to be screwed onto the frame. This improves the wedge's attachment, further enhancing the support of the insulation panel. Working synergistically with the positioning lug, the lug allows for precise positioning of the wedge, which can then be easily screwed in. For example, positioning using the lug allows the wedge to be aligned with a pre-existing screw hole in the frame.

[0049] According to one example, at least one wedge and the plurality of wedge locks are further configured to be fastened together by screwing. After being clipped into place, the wedge and the wedge lock can thus be secured to ensure proper retention of the insulation panel. Preferably, at least one wedge and the plurality of wedge locks are configured to be screwed together in an area separate from the area where the insulation panel is clamped, so that the insulation panel is not penetrated by a screw.

[0050] According to one example, at least one fastening device, and preferably each fastening device and even more preferably each wedge lock, comprises a flexible tab configured to deform, preferably elastically, upon contact with the insulation panel clipped between at least one wedge and the wedge lock. Thus, the fastening device can accommodate different thicknesses of insulation panels.

[0051] According to one example, the door frame does not include an insulating panel.

[0052] According to one example, at least one fastening device being suitable for mounting according to two orientations such that according to a first orientation, at least one wedge is configured to be mounted on a face of a cross member and / or upright opposite the discharge box and according to a second orientation, at least one wedge is configured to be mounted on a face of a cross member and / or upright not opposite the discharge box, and more particularly on a face of a cross member and / or upright located on the side of the inner face of the frame, - at least one wedge is mounted on the frame according to the first orientation, and the insulating panel is put in contact with said wedge so as to be positioned vertically above the outer face of the frame.

[0053] As previously mentioned, on the outer face of the frame, which faces the outside of the room and therefore the wall supporting the pocket door system, the insulating panel can be positioned flush with the frame. This avoids creating an additional thickness against the wall, thus improving the thermal insulation provided by the pocket door system.

[0054] According to one example, at least one fastening device being capable of being mounted in two orientations such that in a first orientation, at least one wedge is configured to be mounted on a face of a cross member and / or upright opposite the discharge box and in a second orientation, at least one wedge is configured to be mounted on a face of a cross member and / or upright not opposite the discharge box, and more particularly on a face of a cross member and / or upright located on the side of the inner face of the frame, - at least one wedge is mounted on the frame according to the second orientation, and the insulating panel is brought into contact with said wedge so as to be positioned on the inner face of the frame.

[0055] As previously mentioned, on the inner face of the frame, the insulating panel can thus be positioned to protrude from the frame, providing improved thermal insulation. This also allows for a reduction in the dimensions of the frame profiles on the inner side, along the transverse Y direction. Indeed, it is not necessary for these profiles to extend in such a way as to contain the inner panel 12 within the recess 104. The cost of the sliding door system is therefore reduced.

[0056] According to one example, the method comprises mounting a first insulating panel, referred to as the "outer panel," using at least one first fastening device. At least one wedge of the first fastening device is mounted on the frame in the first orientation, and the outer panel is brought into contact with the wedge so as to be positioned vertically against the outer face of the frame. The mounting of the inner panel can be followed by the mounting of a second insulating panel, referred to as the "inner panel," using at least one second fastening device. At least one wedge of the second fastening device is mounted on the frame in the second orientation, and the inner panel is brought into contact with the wedge so as to be positioned on the inner face of the frame. This embodiment combines the advantages described above and enhances thermal insulation performance thanks to the use of both inner and outer insulating panels.

[0057] According to one example, the mounting method comprises mounting at least one insulating panel onto the frame, followed by fixing the frame to a wall. The system has The sliding door system can therefore be fully assembled in the workshop before being fixed to the wall. This makes installing the sliding door system even easier and more reliable. Note that the process can be planned to include mounting the exterior insulation panel onto the frame, then fixing the frame to the wall, and finally mounting the interior insulation panel onto the frame.

[0058] In the remainder of this description, terms such as "vertical," "longitudinal," "transverse," "upper," "lower," "front," "rear," "above," "below," "interior," and "exterior" will be used. These terms should be interpreted relatively in relation to the normal operating position of the pocket door system. For example, if the pocket door system is intended to be fixed vertically to a wall, the upper faces of the system 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 system is vertical.

[0059] A reference frame will also be used whose longitudinal or left / right direction corresponds to the X axis, whose transverse or front / back direction corresponds to the Y axis and whose vertical or bottom / up direction corresponds to the Z axis.

[0060] A "monobloc" assembly or set means an assembly or set that is in one piece, or equivalently forms a block, as opposed to an assembly or set made up of separate parts.

[0061] In this patent application, when two parts are described as distinct, this means that these parts are separate. They may be: - positioned at a distance from each other, and / or - mobile relative to each other and / or - joined together, by fixing with or without added elements, this fixing being removable or not.

[0062] The term "on" does not necessarily mean "directly on." Thus, when it is stated that a part or component A is supported "on" a part or component B, this does not mean that parts or components A and B are necessarily in direct contact with each other. These parts or components A and B may be either in direct contact or supported by each other via one or more other parts. The same applies to other expressions such as, for example, the expression "A acts on B," which may mean "A acts directly on B" or "A acts on B via one or more other parts."

[0063] 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, to within 10% or even 5% of that value.

[0064] An element "based" on a material A is understood to be an element comprising that material A and possibly other materials, for example additives.

[0065] The sliding door system 1 is now described according to several particular embodiments, with reference to figures 1 to 9.

[0066] The sliding door system 1, as illustrated in Figures 1 and 8, can be mounted on a wall 2 with an opening. This wall 2 is preferably located at an interface requiring good thermal insulation, for example, a building wall 2 situated at the interface between the interior and exterior, or a wall of an entrance vestibule, the wall 2 being located between the exterior and interior or between two interior spaces. The wall 2 partially delimits a room 3.

[0067] The pocket door system comprises a frame 10. The frame 10 has an inner face 10a intended to face inwards into a room 3 and an outer face 10b intended to face outwards from this room 3, and more specifically towards the wall 2. The frame 10 comprises several profiles, including a bottom rail 100, a top rail 101, and stiles 102. Hereafter, the term "profile" may refer interchangeably to the bottom rail 100, the top rail 101, or a stile 102. Typically, the bottom rail 100 and the top rail 102 each extend along the horizontal direction X. The stiles 102 each extend along the vertical direction Z from the bottom rail 100 to the top rail 101.

[0068] As illustrated, for example, in [Fig. 2], the profiles of the frame 10 form a jamb 103 and at least one recess 104. The jamb 103 defines the opening space of the pocket door system 1, for example, a passageway. The jamb 103 can therefore be positioned opposite an opening in the wall 3. For example, the frame 10 comprises two end posts 102 and one or more intermediate posts 102'. The jamb 103 can, for example, be defined by the bottom rail 100, the top rail 101, an end post 102, and an intermediate post 102'.

[0069] As illustrated in [Fig. 1], the pocket door system 1 further comprises a leaf 11, for example a door, mounted to slide within the frame 10. The leaf 11 is configured to slide along a sliding direction parallel to the horizontal direction X between the frame 103 and the pocket box 104. For this purpose, and in a conventional manner, the leaf 11 may comprise a lower profile configured to cooperate with the lower rail 100 and an upper profile configured to cooperate with the upper rail 101.

[0070] In the closed position of the pocket door system 1, the door leaf 11 occupies the space delimited by the frame 103. The door leaf 11 can occupy a plurality of open positions in which it occupies at least part of the pocket housing 104. Preferably, in the fully open position of the pocket door system 1, the door leaf 11 is concealed within the pocket housing 104. In the following description, The pocket door system 1 is considered to include a sliding door 11 and a retraction box 104.

[0071] The pocket door system 1 may be provided for comprising a plurality of leaves configured to slide within a sliding housing 104; for example, system 1 may comprise two leaves 11 and a sliding housing 104, each leaf 11 being able to slide between the frame 103 and the sliding housing 104. A single sliding housing 104 can therefore accommodate several leaves 11. Alternatively or in addition, the pocket door system 11 may be provided for comprising a plurality of leaves configured to slide within several sliding housings 104; for example, system 1 may comprise two leaves 11 and two sliding housings 104, each leaf 11 being able to slide between the frame 103 and a sliding housing 104, separate for each leaf 11. The sliding housings 104 can be arranged on either side of the frame 103. It is therefore understood that the dimensions of the sliding door system 1 can vary.For example, the sliding door system has a height of approximately 2500 mm, along the z-direction. The sliding door system can have a length along the x-direction of approximately between 2500 mm and 6500 mm (including the discharge box(es) 104).

[0072] Pocket door systems 1 are generally surface-mounted against a wall 3, and more specifically onto the masonry of the wall 3. To achieve thermal insulation, the pocket door system 1 includes at least one insulating panel 12 arranged in the recess 104. The insulating panel 12 may, for example, be an extruded polystyrene sheet, such as Styrodur®. Other types of insulating panels 12 are known to those skilled in the art and may be used within the scope of the invention. The insulating panel 12 may be made of a single element. Alternatively, particularly if the pocket door system 1 is large, the insulating panel 12 may be made of two or more elements. In this case, the elements are arranged so that their faces lie in the same plane. For example, they are placed end to end.

[0073] In order to fix the insulating panel 12 in the pocket door system 1, and more particularly on the frame 10, the pocket door system 1 includes a fixing system 13. The fixing system 13 includes at least one fixing device 13', and preferably a plurality of fixing devices 13', fixed on the frame 10.

[0074] At least one, and preferably each, fastening device 13' comprises at least one wedge 130 and a plurality of wedge locks 131. The wedge 130 is fixed to the frame 10, and more particularly to one of the frame profiles 10. Each wedge lock 131 is configured to cooperate by clipping with a wedge 130 so as to clamp the insulating panel 12 between the wedge 130 and the wedge lock 131. The clamping of the Insulating panel 12 allows for its retention. Preferably, panel 12 is held solely by clipping it into place using one or more fixing devices 13'. The pocket door system 1 is thus installed without drilling the insulating panel 12.

[0075] According to an example not shown, a fastening device 13', and preferably each fastening device 13', may include a wedge 130 cooperating by clipping with several wedge locks 131. For example, the wedge 130 forms a profile fixed to a profile of the frame 10. According to another example shown in [Fig. 1], a fastening device 13', and preferably each fastening device 13', may include several wedges 130, and for example at least two and preferably three wedges 130. Each wedge 130 can cooperate with a wedge lock 131. This thus forms a plurality of point fixing points, preferably distributed around the panel 12. In addition, maintenance of the sliding door system 1 is facilitated since a defective fixing point can be more easily replaced.

[0076] In the following, it is considered, for the sake of completeness, that the sliding door system 1 comprises three fixing devices 13', each fixed respectively to the lower rail 100, an end post 102, and the upper rail 101, these profiles at least partially defining the recessed housing 104. It is further considered that each fixing device 13' comprises several wedges 130, each cooperating with a wedge lock 131. The features and assembly steps described below are nevertheless compatible with the variants mentioned above. It can also be envisaged that fixing devices 13' may have distinct configurations for the same system 1. For example, one device 13' may comprise a wedge 130 cooperating with several wedge locks 131, and another device 13' may comprise a plurality of wedges 130, each cooperating with a wedge lock 131.

[0077] The sliding door system 1 and its assembly method are now described in general terms with reference to figures 1 to 7. Specific examples and embodiment variants will then be detailed.

[0078] The shims 130 can be mounted on the corresponding profile of the frame 10. For this purpose, and as illustrated in Figures 2 and 3, each shim can include a positioning lug 1300 cooperating with an additional housing 105 located in the corresponding profile of the frame 10. The positioning lug 1300 can be configured to snap into the additional housing 105. Thus, the shim 130 can be positioned precisely and reproducibly by a simplified assembly step. According to an alternative or complementary example, each shim 130 can be screwed onto the frame 10 using a screw 132. Preferably, this screwing step takes place after the shim 130 has been positioned on the frame by means of its positioning lug 1300.

[0079] The insulating panel 12 is then brought into contact with each wedge 130 to position it in the discharge chamber 104, as illustrated, for example, in Figures 4 and 5. The wedge 130 thus partially surrounds the panel 12 on a portion of one face and its edge 120. In order to clamp and hold the panel 12, the wedge locks 131 are inserted until they click onto each wedge 130, as illustrated, for example, in [Fig. 6]. Each wedge lock 131 thus partially surrounds the panel 12 on a portion of a face opposite the face in contact with the wedge 130 and on its edge 120. The assembly of the wedge 130 and the wedge lock 131 therefore forms a jaw that clamps the panel 12.

[0080] In addition to clipping, the wedge 130 and the wedge lock 131 can be joined by another means of fastening, for example by screwing by means of a screw 132. This is illustrated for example in [Fig.7].

[0081] The insulating panel 12, once mounted on the frame 10, obscures at least part, and preferably totally, the discharge box 104. Preferably, the frame 103 does not have any insulating panel.

[0082] To simplify the figures, Figures 2 to 7 illustrate the mounting of only one insulating panel 12 on the inner face 10a of the frame 10, referred to as the "inner panel." An insulating panel 12 may, alternatively or in addition, be mounted vertically on the outer face 10b of the frame 10, as illustrated in [Fig. 8]. Equivalently, the insulating panel 12 "vertically" is at least partially contained within the space defined by the frame 10 between its profiles. With respect to the upper crossbar, the insulating panel 12 may be at least partially positioned below the lower crossbar in projection onto a horizontal plane. With respect to the lower crossbar, the insulating panel 12 may be at least partially positioned on the lower crossbar in projection onto a horizontal plane.It is therefore understood that when it is specified that panel 12 is mounted vertically above the outer face of the frame, the outer face of the insulating panel 12 may be slightly recessed from the outer face of the corresponding frame profile 10.

[0083] The sliding door system 1 is now described in more detail with reference to Figures 8 and 9.

[0084] According to the illustrated example, the lower 100 and upper 101 crossbars comprise several profiles, for example, an inner profile 1000, 1010, and an outer profile 1001, 1011. Each inner profile can be joined to the outer profile by means of a thermal break profile 1002, 1012. The inner profile 1000 may include a portion 1013 on which a rail can be mounted, the leaf 11 sliding in cooperation with the rail. The inner profile 1010 may include a portion 1014 on which the leaf 11 cooperates by complementary shape, preferably with a sealing gasket (not shown). The upright 102 may comprise several profiles, for example, an inner profile 1020, a profile exterior 1021. The interior profile 1020 can be joined to the exterior profile 1021 by means of a thermal break profile 1022.

[0085] The system 1 may preferably include two insulating panels 12. A first insulating panel 12, called the "outer panel", may be placed vertically on the outer face 10b of the frame 10. A second insulating panel 12, called the "inner panel", may be placed on the inner face 10a of the frame 10. Better thermal insulation is thus obtained.

[0086] Positioning the outer panel 12 directly above the frame 10 prevents the outer panel from protruding beyond the frame 10. This allows the frame 10 to be flush against the wall 2, minimizing the gap between them. It is understood that the outer panel 12 can be contained within the discharge box 104. The gap between the frame 10 and the wall 2 can be sealed with a gasket 20, for example, a sealing foam or a silicone sealant.

[0087] The inner panel 12 is preferably mounted projecting from the frame 10, along the transverse direction Y. Preferably, the inner panel 12 at least partially covers the frame 10. Alternatively, the inner panel 12 can also be mounted flush with the inner face 10a of the frame 10. However, this requires additional material in the frame 10 profiles, which would result in an additional cost. Furthermore, the fact that the inner panel 12 at least partially covers the frame 10 provides better thermal insulation through the sliding door system 1.

[0088] Due to the different arrangement of the insulating panels 12 between the inner face 10a and the outer face 10b of the frame 10, the fixing device 13' can have two orientations configured to allow these different mountings. More specifically, the wedge 130 can be configured to be fixed to the frame 10 and allow cooperation with the edge 120 of the panel 12 in two different orientations. Thus, the same fixing device 13' can be used, which simplifies the assembly of the sliding door system 1 and reduces its manufacturing cost. This is now described in more detail for one fixing device 13', it being understood that this can be applied to a plurality of fixing devices 13'.

[0089] As illustrated for example in [Fig. 8], a fixing device 13' can be mounted, in a first orientation, on an upper face 100c of the lower cross member 100. A fixing device 13' can be mounted, in the first orientation, on a lower face 101c of the upper cross member 101. Similarly, as illustrated for example in [Fig. 9], a fixing device 13' can be mounted, in the first orientation, on a transverse face 102c of a post 102, opposite the discharge box 104. Thus, the outer faces 100b, 101b, 102b of the lower cross member 100 and the upper cross member 101 and of the post 102 can be directly opposite the wall 2.

[0090] For the second orientation, as illustrated for example in [Fig. 8], a fastening device 13' can be mounted on an inner face 100a of the lower cross member 100. A fastening device 13' can be mounted on an inner face 101a of the upper cross member 101. Similarly, as illustrated for example in [Fig. 9], a fastening device 13' can be mounted on an inner face 102a of a post 102.

[0091] The wedge 130 can be mounted on the corresponding profile by means of the same face 130c of the wedge 130, regardless of the orientation of the fastening device 13'. One, and preferably two, positioning lugs 1300 can in particular be arranged on this face 130c opposite the corresponding face of the profile. The additional recesses 105 can be arranged on the corresponding face of the profile.

[0092] The wedge 130 and the wedge lock 131, and their cooperation with the insulating panel 12, are now described in more detail with reference to figures 10 to 15.

[0093] The wedge is described with reference to Figures 10A to 10C. The wedge 130 is configured to allow the wedge lock 131 to be clipped in either of these two orientations. To this end, the wedge 130 comprises a first 130a and a second 130b support surfaces, arranged substantially perpendicular to each other. As illustrated by [Fig. 14], each wedge lock 131 is then configured to: - in the first orientation, slide along the first support surface 130a until it reaches a clip-in position, - in the second orientation, slide on the second support surface 130b until it reaches a clip-in position.

[0094] In the first orientation, the fastening device 13' is configured to clamp the insulating panel 12 between the second support surface 130b and the wedge lock 131, as illustrated, for example, in Figures 8 and 9. The fastening device 13' thus defines a jaw delimited by the second support surface 130b and the wedge lock 131, into which the insulating panel 12 is inserted. In the second orientation, the fastening device 13' is configured to clamp the insulating panel 12 between the first support surface 130a and the wedge lock 131, as illustrated, for example, in Figures 8 and 9. The fastening device 13' also defines, in this orientation, a jaw delimited by the first support surface 130a and the wedge lock 131, into which the insulating panel 12 is inserted.

[0095] The wedge 130 can more specifically have a right-angled shape, with two portions extending along principal directions of extension perpendicular to each other. Those skilled in the art can design other configurations to achieve the two desired orientations. The wedge 130 is of monobloc preference. Face 130c of wedge 130 may have the positioning lug(s) 1300. This face 130c may also have an opening 1301 for the passage of a screw 132 for screwing it onto the frame 10 as illustrated in figures 12A and 13A.

[0096] The wedge lock is described with reference to Figures 11A and 11B. For its clipping onto the wedge 130, the wedge lock 131 may include a first surface 131a intended to be slidably mounted on the corresponding surface of the wedge 130. The wedge lock 130 may further include clipping tabs 1311 configured to cooperate by clipping with additional housings 1302 of the wedge 130. These additional housings 1302 are more particularly located at the end of the sliding movement of the wedge lock 131 on the wedge 130, for each of the orientations of the fastening device 13', as illustrated in [Fig. 14].

[0097] Furthermore, the wedge lock 131 may include stops 1312 configured to grip the wedge 130 when the wedge lock 131 is in its clipped position on the wedge 130. Thus, once the wedge lock 131 is clipped, movement of the wedge lock 131 on the wedge 130 is prevented. To achieve this, the stops 1312 may come into contact with complementary surfaces 1303 of the wedge 130, these surfaces being more specifically opposite to the sliding surface 130, 130b of the wedge 130, depending on the orientation of the fastening device 13'.

[0098] In addition to clipping the wedge lock 131 onto the wedge 130, the latter can be secured by an additional fastening element. For example, as illustrated in Figures 12A to 13B, for each orientation the wedge lock 131 can be screwed onto the wedge 130 by means of a screw 133. For this purpose, the wedge lock 131 may include an opening 1313, the opening 1313 extending opposite a complementary opening 1304 in the wedge 130 for each orientation. Thus, the retention of the insulating panel 12 is further improved. This can also serve to clamp the fastening device 13', for example, for its transport.

[0099] The wedge lock 131 may include a surface 131b intended to be in contact with the edge 120 of the insulating panel 12, as illustrated for example in [Fig. 15]. Alternatively, a surface of the wedge 130 may be provided to be in contact with the edge 120 of the insulating panel 12.

[0100] To hold the insulating panel 12, the wedge lock may further include a flexible tab 1310. As illustrated in [Fig. 15], the flexible tab 1310 can be configured to deform, preferably elastically, upon contact with the insulating panel 12 held in place by the clip of the wedge 130 and the wedge lock 131. Thus, the fastening device 13 can accommodate a variation in thickness Ad of the insulating panel 12. The flexible tab 1310 can, in particular, partially define laterally the jaw into which the insulating panel 12 is inserted, as discussed previously. According to an example, the thickness of the insulating panel 12 can vary between a length dl and d2, typically between 25 and 35 millimeters, preferably between 28 and 30 millimeters, depending on the transverse direction Y. The fixing device 13' is thus compatible with the manufacturing tolerances between the insulating panels 12, or even different types of insulating panels 12 not having the same thickness.

[0101] According to one example, the flexible tab is deformable under the mechanical action of the insulating panel 12. According to another example, the flexible tab is deformable under the finger of a user with manual pressure, without tools. This facilitates assembly by an operator. The flexible tab may have a Shore hardness of substantially between 80 and 100 Shore D, preferably substantially equal to 90 Shore D.

[0102] According to one example, the wedge and the wedge lock are made of polyamide, for example polyamide 6-6, preferably with a glass fiber filler of approximately 30% by mass. Preferably, the wedge and the wedge lock can each be one-piece, for example, these elements are injection-molded. In view of the foregoing description, it is clear that the invention provides a solution facilitating the installation of a pocket door with good thermal insulation.

[0103] The invention is not limited to the embodiments described above and extends to all embodiments covered by the invention. The present invention is not limited to the examples described above. Many other embodiments are possible, for example by combining features described above, without departing from the scope of the invention. In particular, the pocket door system 1 may comprise only an interior insulating panel 12, or only an exterior insulating panel 12, or both. Furthermore, as mentioned above, the pocket door system 1 may comprise two recessed housings 104 arranged on either side of the frame 103, each configured to receive one or two insulating panels 12.

[0104] Furthermore, the features described with respect to one aspect of the invention can be combined with another aspect of the invention. In particular, the assembly method can include any step resulting from or enabling the obtaining of a feature of the sliding door system 1, and conversely the sliding door system 1 can exhibit any feature resulting from the implementation of the method.
