Title of the invention: SLIDING DOOR ASSEMBLY Scope of the invention

[0001] The field of the invention is that of sliding door assemblies.

[0002] These assemblies conventionally comprise rails intended to be mounted on a Embrature defining a rectangular opening to form a frame and sashes intended to be mounted to slide horizontally on these rails.

[0003] The invention applies more particularly to lightweight hinged assemblies with plastic panels, for example vinyl and / or including a mosquito net and configured so that these leaves are suitable for being mounted removably on the rails.

[0004] This allows for the easy closure of an opening delimited by a pergola-type structure in order to protect its occupants from rain, wind, and / or ultraviolet rays and / or insects, as well as for changing the panels according to the seasons. The panels are also easy to remove due to their lightweight plastic or mosquito netting.

[0005] One object of the invention is to offer a sliding door system compatible with access for persons with reduced mobility (PRM) at a lower cost.

[0006] To this end, the invention relates to a sliding door assembly intended to be mounted on an opening comprising flat faces delimiting and surrounding a substantially rectangular opening, each door comprising a panel of a translucent film elastically deformable and / or a mosquito net panel and rollers, the assembly comprising a set of rails suitable for being installed in a tunnel on the flat faces of the opening so as to form a frame comprising a threshold formed by a lower rail of the set of rails and such that the doors are intended to be mounted sliding in a removable manner on the frame, the lower rail having a first height less than or equal to 2.5 cm.

[0007] Advantageously, the assembly comprises at least one elastically deformable translucent film which is a shape memory vinyl film.

[0008] Advantageously, the sleeper comprises an upper cross member formed by an upper rail of the rail assembly, the upper rail having a second height greater than the first height.

[0009] Advantageously, each rail of the rail assembly has a base intended to be opposite a flat face of the support frame when the rail assembly is placed in a tunnel on the embrasure so as to have the function of a fixed frame.

[0010] Advantageously, each rail comprises supports parallel to the bottom, facing the bottom, and by which the rail is intended to rest on the flat face when The rail assembly is laid in a tunnel on the embrasure so as to present the function of a fixed support, the rail comprising transverse edges extending continuously from one of the supports to the bottom.

[0011] Advantageously, each rail in the rail assembly comprises a set of transverse walls extending from one side of the bottom so as to limit adjacent housing along the transverse axis and receiving the leaves when they are mounted sliding in a removable way on the frame.

[0012] Advantageously, each leaf is configured so as to be intended to extend within a single housing of the lower rail when mounted on the frame.

[0013] Advantageously, the set of transverse walls comprises two extreme transverse walls transversely delimiting the bottom and intermediate transverse walls arranged between the extreme transverse walls, only one of the extreme transverse walls of the bottom rail and each of the intermediate transverse walls of the bottom rail being crossed by at least one drainage opening.

[0014] Advantageously, two rails of the rail assembly each have protruding gutters on the bottom of the rail, the gutters being intended to receive screws passing through openings made in the bottoms of the other two rails so as to form a closed frame.

[0015] The invention also relates to a sliding door system comprising a sliding door assembly according to the invention, in which the doors are mounted sliding in a demountable manner on a mounting frame formed from the rail assembly of the sliding door assembly.

[0016] The invention also relates to an installation comprising the embrasure and the sliding leaf system mounted on the embrasure so that the rail assembly is laid in a tunnel on the embrasure so as to present a fixed function.

[0017] The invention also relates to a method of mounting an assembly (S) according to the invention, on a door opening: • Position the entire set of rails in the tunnel on the opening so as to provide a fixed support function, • mount the sliding leaves in a removable manner on the frame.

[0022] [Fig.4]: a schematic representation of a section along a plane perpendicular to [Fig.2] and to the second direction D2, of the lower and upper rails mounted on the embrasure. Description of the invention

[0023] The invention relates to a sliding V-leaf assembly E as represented in [Fig.1],

[0024] The assembly E includes leaves V and a set of rails ER intended to be mounted on an embrasure EMB such that the set of rails ER forms a mounting frame CM having a fixed function and the leaves V are mounted sliding in a removable manner on the mounting frame CM.

[0025] The EMB embrasure delimits and surrounds a rectangular opening OUV referenced on [Fig.2] delimiting an interior space from an exterior space.

[0026] The EMB embrasure has a certain predetermined thickness along an axis perpendicular to the plane of the opening OUV, which we will call the transverse axis T in this patent application. This axis is perpendicular to the plane of [Fig.2].

[0027] The EMB embrasure comprises a top crossbar TS, two uprights MT1, MT2 and a threshold of the SEMB embrasure.

[0028] By upper cross member TS, we mean a cross member extending above the threshold of the SEMB embrasure.

[0029] By horizontal direction is meant a direction perpendicular to the gravitational force defined at the level of assembly E. By vertical axis is meant an axis perpendicular to the horizontal direction and extending from the center of the Earth outwards. The terms above, below, and over are defined with respect to the vertical direction. An element is above another element if it is located at a higher elevation than the other element along the vertical axis.

[0030] The EMB embrasure comprises flat faces facing the OUV opening so as to delimit the OUV opening. In other words, each of the jambs MT1, MT2, upper rail TS and threshold of the SEMB embrasure has a flat face delimiting the OUV opening as seen in Figures 3 and 4. Doors

[0031] The assembly E includes leaves V.

[0032] In the non-limiting example of Figures 1 and 2, each leaf V comprises two rectangular or substantially rectangular translucent panels P.

[0033] In an embodiment, at least one panel is a film.

[0034] The film is advantageously elastically deformable.

[0035] Advantageously, the film is elastically deformable so as to be able to go through an elastic deformation from a planar rest configuration in which it presents a planar face to a deformed configuration in which it presents a three-dimensional face, under the effect of a force exerted on the film having a component perpendicular to the planar face.

[0036] Advantageously, the film has shape memory so as to return to its planar rest configuration from its deformed configuration when the force ceases.

[0037] The film is, for example, made of plastic.

[0038] The film is, for example, a vinyl, for example a shape memory vinyl.

[0039] Advantageously, the film has undergone an anti-ultraviolet treatment.

[0040] Advantageously the panels are coplanar.

[0041] Advantageously at least one translucent panel is transparent.

[0042] According to a particular embodiment, at least one leaf V includes a mosquito net panel.

[0043] Generally, the assembly E includes at least one leaf V comprising at least one panel, for example one or more panels, in the form of a mosquito net and / or at least one shape memory vinyl panel and / or at least one plastic panel.

[0044] Each leaf V includes a structural frame CS with a rectangular or substantially rectangular cross-section surrounding the panel P and ensuring the mechanical support of the leaf V.

[0045] The structural frame CS comprises two first opposing bars Bl, B2 extended along the same first direction DI and two second bars B3, B4 extended along the same second direction D2 perpendicular to the first direction.

[0046] In the embodiment of [Fig. 1], each leaf V includes at least one reinforcing bar BR extending from the third bar B3 to the fourth bar B4. This reinforcing bar BR ensures better wind resistance of the leaf panel V as well as good support of the panels P.

[0047] Each panel is delimited by the reinforcement bar BR and the structural frame bars CS.

[0048] Advantageously, the first two bars Bl, B2 are intended to be extended in a horizontal direction when the leaf V is mounted sliding on the set of rails ER forming a mounting frame CM having the function of a fixed frame.

[0049] Advantageously, the reinforcement bar BR is parallel or substantially parallel to the first two bars.

[0050] Advantageously, the structural CS frame includes tensioning means configured to keep each panel taut.

[0051] Each leaf V includes rollers R mounted on the structural frame CS and more particularly on the lower RI rail of the structural frame, which will be described later. This ensures easy mounting of the casters.

[0052] Advantageously, the rollers R are mounted on the rail RI so that a distance between the rollers and the rail RI is adjustable.

[0053] Each leaf V also includes one or more RS springs, for example two springs in the example of [Fig. 1] as we will see later. Rail assembly

[0054] The ER rail assembly comprises several rails and is intended to be mounted on the EMB embrasure, within the OUV opening, to form a frame.

[0055] Each rail R is advantageously a metal profile, for example aluminium.

[0056] Thus each rail R is advantageously monobloc.

[0057] Advantageously, the rails are mounted on the EMB embrasure so as to form a closed CM mounting frame having a fixed function.

[0058] The closed mounting frame CM advantageously has a rectangular section in the opening plane OUV.

[0059] Advantageously, the R rails of the ER rail assembly are intended to be assembled by a nut-and-screw system and optionally via sealing strips or pads PL referenced on [Fig.1], so as to form the mounting frame CM before being mounted on the EMB opening.

[0060] PL sealing strips or pads are intended to be interposed between two adjacent rails so as to ensure the sealing of the connection between these two adjacent rails.

[0061] The sealing strips advantageously have predetermined dimensions and predetermined elasticity characteristics so as to be compressed to ensure the sealing of the connections between the rails when they are assembled to form the CM mounting frame.

[0062] The sealing strips are, for example, made of foam.

[0063] Alternatively, the CM mounting frame is formed by mounting on the EMB embrasure.

[0064] As seen in [Fig.1], the ER rail assembly comprises an upper rail RS, a lower rail RI, and two side rails RL1, RL2 of the CM or fixed mounting frame.

[0065] As seen in [Fig.2], the upper rail RS is intended to be mounted on the upper cross member TS of the EMB embrasure, the lower rail RI is intended to be mounted on the threshold of the SEMB embrasure and the side rails RL1, RL2, are intended to be mounted on uprights MT1, MT2 of the EMB embrasure so as to form the frame.

[0066] The lower rail RI then forms the threshold of the frame and the upper rail forms the upper crossbar of the frame.

[0067] Each of the uprights MT1, MT2 extends longitudinally from the lower rail RI to the upper rail RS when the set of rails RS forms the mounting frame CM.

[0068] The lower rail RI and the upper rail RS are advantageously elongated and extend straight along respective longitudinal axes parallel to a horizontal direction when the mounting frame CM is mounted on the embrasure.

[0069] The side rails RL1, RL2 are advantageously elongated and extend straight along respective longitudinal axes parallel to a vertical direction when the mounting frame CM is mounted on the embrasure.

[0070] According to the invention, the ER rail assembly is configured so as to be able to be installed in a tunnel on the flat faces of the embrasure EMB so as to form the mounting frame CM having the function of a fixed frame on which the leaves V are intended to be mounted sliding in a removable manner.

[0071] Tunnel installation is advantageously carried out solely by drilling and screwing.

[0072] In other words, in order to form the CM mounting frame having the function of a sleeper, the ER rail assembly is configured so as to be able to be placed on the EMB opening so that the resultant of the forces exerted by the EMB opening on each of the rails of the ER rail assembly is in the plane of the OUV opening, i.e. in a vertical plane.

[0073] In other words, in order to form the CM mounting frame having the function of a sleeper, the ER rail assembly is configured so as to be able to be placed on the EMB recess so that each of the rails of the ER rail assembly is supported on a single flat face Fl, F2, F3, F4 of the EMB recess facing the EMB recess.

[0074] Thus, each rail RI, RS, RL1, RL2 of the CM mounting frame is able to protrude on one side of a plane formed by a flat face Fl, F2, F3, F4 of the EMB embrasure facing the OUV opening and delimiting the OUV opening on which it is intended to rest so as to form the frame.

[0075] Furthermore, according to the invention, the ER rail assembly is configured such that, when the CM mounting frame is tunnel-mounted on the EMB opening, the lower rail RI is able to protrude from the flat face Fl of the SEMB opening threshold to a first height H1 less than or equal to 2.5 cm. This is the case when the lower rail RI is in direct physical contact with the flat face Fl of the SEMB opening threshold. The first height H1 is taken perpendicular to the flat face FL.

[0076] In other words, the lower rail RI has a first height H1 less than or equal to 2.5 cm.

[0077] This allows easy mounting of the E assembly on the EMB embrasure and is compatible with the installation of a ramp allowing a person with reduced mobility to pass through the opening delimited by the CM mounting frame.

[0078] In one example, the first height is equal to 2.23 cm.

[0079] Advantageously, the lower rail RI has a first height H1 included between 2 cm and 2.5 cm. This helps to limit water entry from the outside.

[0080] Advantageously, the first height H1 is less than a second height H2 over which the upper rail RS extends transversely to the flat face F2 of the upper cross member TS on which the upper rail RS rests. This is the case when the upper rail RS is in direct physical contact with the flat face F2 of the upper cross member TS of the opening EMB. The second height H2 is taken perpendicular to the flat face F2.

[0081] In other words, the lower rail RI has a first height H1 less than or equal to a second height H2 of the upper rail RS.

[0082] This large height of the upper rail RS ensures that the leaves are held securely in the CM mounting frame and thus provide good wind resistance.

[0083] Advantageously, the second height H2 is between 3 and 5 cm.

[0084] In one example, the second height is equal to 4.42 cm.

[0085] Advantageously, each of the rails of the ER assembly includes a base FD intended to be opposite the embrasure EMB when the ER assembly is mounted on the embrasure EMB so as to have the function of a fixed frame.

[0086] The bottom FD is substantially flat and elongated and extends straight along a longitudinal axis of the lower rail RI along which the lower rail RI is elongated.

[0087] It should be noted that the heights of each of the lower and upper rails H1 and H2 are taken perpendicular to the bottom FD of the corresponding rail.

[0088] Each of the rails also includes transverse walls marked PT1, PT2, PT3, PT4 for the lower rail RI; PT1', PT2', PT3', PT4' for the upper rail RS; PTL1, PTL2, PTL3, PTL4 for the side rails, adjacent along a transverse axis of the bottom FD perpendicular to the longitudinal axis of the rail and intended to extend along the transverse axis T when the rail assembly ER has the function of a sleeper.

[0089] The longitudinal axis of each rail is perpendicular to the plane of [Fig. 3], respect 4. The transverse axis of the rail is included in the plane of the bottom and that of the [Fig.3], respectively. 4. The transverse axis of each rail R is parallel to the transverse axis T when the set of rails ER is mounted on the embrasure EMB so as to present the function of a fixed frame.

[0090] Each of the transverse walls marked PT1, PT2, PT3, PT4; PT1', PT2', PT3', PT4'; PTL1, PTL2, PTL3, PTL4 protrudes from the bottom FD on one side of the plane formed by the bottom FD of the corresponding rail.

[0091] The transverse walls PT1, PT2, PT3, PT4, ; PT1', PT2', PT3', PT4' ; PTL1, PTL2, PTL3, PTL4 ; delimit elongated housings L extending straight along axes parallel to the longitudinal axis of the corresponding rail and adjacent along the transverse axis of the rail. Each housing is delimited by two transverse walls adjacent along the transverse axis of the corresponding rail.

[0092] Housings L are intended to receive leaves V.

[0093] In the non-limiting example of the figures, each rail comprises four transverse walls delimiting three housings L.

[0094] This number of dwellings is in no way limiting.

[0095] Alternatively, each R rail has five transverse walls to delimit four compartments. This allows for a greater number of door leaves, thus providing greater flexibility in their arrangement.

[0096] A larger or smaller number of transverse walls and therefore of dwellings can of course be envisaged.

[0097] Advantageously, each housing L has a width, that is to say a dimension along the transverse axis of the corresponding rail, of between 15 mm and 25 mm.

[0098] Advantageously, in order to allow the assembly of the mounting frame CM prior to their placement on the embrasure EMB, the transverse walls PTL1, PTL2, PTL3, PTL4 of the side rails RL1, RL2 extend along the longitudinal axis of the rail, as seen in [Fig.1], only on a central part of these rails so as to leave free the two longitudinal ends of the bottom FD of each of these rails which are pierced with holes TR spaced along the transverse axis of the corresponding rail.

[0099] Advantageously, each of the lower and upper rails RI, RS includes gutters Gl, G2 projecting on the bottom of the second side of the bottom, spaced along the transverse axis of the rail and intended to receive and guide screws passing through respective holes TR piercing the bottoms of the side rails RL1, RL2, optionally through respective sealing pads PL, so as to form the mounting frame CM.

[0100] Advantageously, each gutter Gl, G2 is elongated and extends straight along an axis parallel to the longitudinal axis of the corresponding rail.

[0101] Advantageously, each gutter Gl, G2 has a substantially circular section in a plane perpendicular to the longitudinal axis of the corresponding rail.

[0102] The Gl, G2 gutters also have a rail reinforcement function which helps to limit the risks of rail deformation.

[0103] The bottom FD is delimited transversely by two of the extreme transverse walls PT1, PT2; PT1', PT2'; PTL1, PTL2 between which are arranged the other transverse walls, called intermediate transverse walls PT3, PT4; PT3', PT4'; PTL3, PTL4.

[0104] Advantageously, each of the rails is delimited along its transverse axis by two bases BAI, BA2 each comprising a support SI, S2 substantially planar, parallel to the bottom FD and facing the bottom FD and a transverse edge PI, P2 each extending from one of the supports SI, S2 to the bottom FD.

[0105] The support SI, S2 and the wall PI, P2 of each base BAI, BA2 are elongated according the longitudinal axis of the corresponding rail.

[0106] The two bases BAI, BA2 protrude on the other side of the plane formed by the bottom FD of the rail with respect to the transverse walls PT1, PT2, PT3, PT4 of the same rail.

[0107] Advantageously, as in the non-limiting example in the figures, the wall PI, P2 is substantially perpendicular to the bottom FD.

[0108] Advantageously, as in the non-limiting example in the figures, each of the transverse edges PI, P2 extends one of the transverse walls PT1, PT2; PT1', PT2'; PTL1, PTL2 extreme.

[0109] Advantageously, the transverse walls PT1, PT2, PT3, PT4 of the transverse rail RI have a height less than the height of the transverse walls of the upper rail RS and the bases BAI, BA2 of these rails have the same height.

[0110] The height of each of the walls and base is taken perpendicular to the bottom FD of the corresponding rail.

[0111] Advantageously, each of the rails is intended to be supported on one of the flat faces Fl, F2, F3, F4 by means of its supports SI, S2 when it is mounted so that the set of rails ER forms the mounting frame CM having the function of a sleeper.

[0112] Advantageously, the rails are laid in a tunnel on the embrasure only by screwing and possibly prior drilling.

[0113] The rails are for example pre-drilled and milled before being screwed onto the EMB embrasure.

[0114] Alternatively, the rails include holes for receiving the screws for screwing them onto the EMB embrasure.

[0115] Advantageously, only one of the extreme transverse walls, the first extreme transverse wall PT1 of the lower rail RI, and each intermediate transverse wall PT3, PT4, are traversed by at least one drainage opening or several drainage openings spaced along the longitudinal axis of the rail. The drainage openings allow water to be evacuated from the housings to the exterior space delimited by the extreme transverse wall PT1 without the water flowing into the interior space delimited by the second extreme transverse wall PT2. Furthermore, these openings are easy to construct.

[0116] In the non-limiting example in the figures, the lower rail RI includes two drainage openings O spaced along the longitudinal axis of the rail and the drainage openings of the intermediate transverse walls are not visible.

[0117] This rail configuration ensures good sealing. Reinforcement

[0118] Advantageously, at least of the R rails have an RF reinforcement projecting onto the FD bottom on the same side of the bottom as the BAI, BA2 bases.

[0119] Advantageously, the RF reinforcement and the BAI, BA2 bases are configured so that the R rail is intended to be supported, solely by supports SI, S2 and the optional RF reinforcement, on the corresponding flat face of the EMB opening to form the frame. This helps to limit the risk of rail deformation.

[0120] Advantageously, the rail R is intended to be in direct physical contact, solely via supports SI, S2 and the optional RF reinforcement, with the corresponding flat face of the EMB opening to form the frame. This helps to limit the risk of rail deformation. Door assembly

[0121] The V leaves are intended to be mounted sliding in a removable manner on the CM mounting frame forming the fixed part.

[0122] The leaves V together with the mounting frame CM on which they are mounted form an S system of sliding leaves.

[0123] This system separates the interior space from the exterior space.

[0124] Advantageously, the rails of the ER rail assembly are intended to be mounted on the EMB embrasure so that the leaves V can be mounted in a demountable manner on the CM mounting frame forming the frame.

[0125] To this end, when the rails are assembled and / or mounted on the EMB embrasure to form the CM mounting frame, the rails are arranged so that the transverse walls of the mounting rails facing each other face each other, so that the recesses they define are aligned along their entire length. This allows the leaves to be slid into the recesses.

[0126] Advantageously, the leaves V are intended to be mounted sliding so as to be able to slide along the longitudinal axis of the lower rail RI and the upper rail RS.

[0127] Thus, the V leaves slide horizontally.

[0128] Advantageously, when the V leaves are mounted on the CM mounting frame, each V leaf extends transversely only between two adjacent transverse walls of each of the lower and upper rails.

[0129] In other words, each of the leaves V is received within a single housing of each of the lower and upper rails.

[0130] Moreover, each leaf is able to extend transversely only between two adjacent transverse walls of one of the two lateral rails.

[0131] For this purpose, each leaf V has a thickness less than or equal to the width of each housing.

[0132] Each leaf advantageously has a thickness between 12 mm and 24 mm.

[0133] The thickness is, for example, 18 mm.

[0134] Advantageously, the V leaves and the CM mounting frame are configured so that the V leaves are able to close the opening delimited by the CM mounting frame as seen in [Fig.2] when mounted on the CM mounting frame.

[0135] As seen previously, each leaf V advantageously includes at least one spring RE (two springs in the non-limiting example of [Fig.1]) intended to bear against the upper rail RS when the leaf V is mounted sliding on the mounting frame CM.

[0136] Advantageously, the leaf V is configured so that the spring(s) RE allows an operator to mount the leaf V onto the mounting frame CM when the latter is mounted on the embrasure EMB, by implementing the following steps: - placing the spring(s) RE against a part of the bottom FD delimiting a first so-called upper housing of the rail RS, - then lift the leaf V so as to compress the spring(s) to allow the rollers R to slide on a part of the bottom FD of the lower rail RI, defining a second housing of the lower rail RI opposite the first housing of the upper rail RS, - to rest the V leaf.

[0137] Such a configuration allows for easy and secure mounting and dismounting of the V-leaf on the CM mounting frame.

[0138] Each spring RE is, for example, a leaf spring extending from a first end of the leaf spring to a second end of the leaf spring. The first end and the second end are fixed to the structural frame CS.

[0139] Advantageously, the dimensions of the mounting frame CM are defined such that the spring(s) RE are under tension when the leaf V is mounted on the mounting frame CM, so that the spring RE exerts a force F on the mounting frame CM via the rollers. This ensures that the leaf V is held securely in the first and second housings.
