Description

FIELD

The field of the invention relates to a furniture system making it possible to arrange private, public or professional environments such as: homes, offices, shops, museums, etc. The field of the invention relates to the field of modular furniture systems making it possible, among other things, to design storage furniture, but also other interior arrangements of very diverse shapes. Finally, the field of the invention relates more particularly to structures making it possible to produce such a system of modular furniture by assembling panels. In addition, the invention also relates to the methods of manufacturing said panels, as well as the methods of mounting this system.

STATE OF THE ART

Standardized furniture cannot meet all the criteria for a layout project. The custom manufacture of furniture, for its part, requires a dedicated study which is often restrictive.

Custom furniture is designed for a specific environment and use, a change of space or changing needs will most of the time lead to its complete replacement.

So-called “modular” furniture systems are made up of simple elements that are assembled together in order to obtain a desired geometry and function. They thus have the advantage of allowing many combinations of shapes, of being easily removable, transportable and upgradeable.

Although these systems are versatile, the furniture will only be able to adapt approximately to the geometric constraints and dimensions of its place of installation. Mass production involves a fairly limited range of shapes and finishes.

For example, the Swiss company USM HALLER offers a very successful modular furniture system. It is a system made up of tubes interconnected by connecting pieces, so as to form a framework. This skeleton is then dressed in panels and other equipment.

Today there is a need and a market for a new type of hybrid furniture, allowing truly tailor-made products and combining the advantages and flexibility of modular systems.

A "channel section" is a section comprising a longitudinal internal channel. The channel can be opened or closed, for example by a finishing profile. According to one example of the invention, the channel forms a groove. A first function of the groove is to accommodate a branch of a connector in each end of the profile. Another function of the channel is to house one or more cables, wires or any other equipment and connectors.

A "finishing profile", or cover profile is a longitudinal profile creating a closing surface of the groove formed in the longitudinal edge. When the groove is produced by a channel profile, the finishing profile comprises a junction element, such as a clip or a hook to join with the channel profile.

A “radial cut” is a cut generating a facet on the lateral edge B _lat of a panel P _i , it is denoted 20. When two cuts 20 are made on a lateral edge B _lat of a panel P _i and the angles of the cuts are less than 90 °, said lateral edge may form a point. On the figure 3 , the radial section is represented by the angle β / 2. The angle is, for example, defined between the longitudinal plane of a panel and a section of the lateral edge B _lat .

According to one embodiment, the two angles may be equal, for example by a value of 45 °. According to another example, an angle of a first radial cut is 45 ° and an angle of a second radial cut of the same edge B _lat is 90 °. Each angle is measured between the radial section considered and the longitudinal plane of the panel. The sum of the angles of each radial section forms the total angle between the two radial sections of the same edge B _lat . This total angle is for example 90 ° if each radial section is 45 °. The total angle is 135 ° if a first radial cut has an angle of 45 ° and a second radial cut has an angle of 90 °.

A radial section is an angular section pivoting about the central axis 15 of the joining nodes. The central axis 15 of the assembly nodes is a straight line defined by the intersection of the median planes of the panels. When assembling three or more panels, the cuts radials generate on each side edge of a panel, two intersecting planes, also called facets.

According to the embodiments, the angle between these planes is, for example, 90 ° during an assembly comprising four orthogonal panels.

In the case of a structure of panels forming regular hexagons, the angle between these planes is 120 °, which makes it possible to assemble three panels together.

A "panel" is a flat surface that can refer to a sandwich panel, a composite panel, or a panel of a single material. It can, for example, act as a shelf or as an upright depending on its orientation. It can be made of wood or aluminum, for example. In the context of the invention, the panel can be machined and / or include elements such as a profile arranged on one or more of its edges. According to one example, the panel can include a coating. It can be made of a single material or it can be made up of different parts. A panel in the invention is denoted by P _i in the general case and P ₁ and P ₂ when a particular structure comprising two panels is mentioned.

A "coating" denotes a finishing material, for example a veneer, a lacquer, a varnish.

A "central web" designates the internal part of the panel which is generally not visible. It can be understood as the constituent part of the body of the panel. It is sandwiched between the face coverings and the panel channel profiles.

A technical channel is a continuous sheath between the different panels of a structure for the passage of cables, conductors, LED strips and other technical components. The radial section assembly method allows the formation of a technical channel extending along different panels without discontinuity. This channel makes it possible, for example, to pass a power supply cable from the foot of a piece of furniture to an integrated luminaire.

The figure 1 shows an embodiment of a panel P ₁ of the invention. According to one embodiment, a panel P ₁ comprises a central core 2, a finishing coating 3 and two channel profiles 4 extending the ends of the longitudinal edges 9 of the central core 2 and respectively parallel to said longitudinal edges 9. According to one embodiment preferred embodiment, each panel P _i comprises two longitudinal sections arranged at each end of each longitudinal edge of said panel P _i . This configuration makes it possible to produce a panel having a symmetry along the OYZ plane.

The figure 1 shows a sandwich panel P ₁ in which a finishing coating 3 is affixed to the two opposite faces F of the central core 2. According to one embodiment, the finishing coating 3 is applied to the opposite faces F of the core central 2 and extends beyond the longitudinal edges B _lon of said central core 2. According to one embodiment, a channel section 4 extends the longitudinal edge 9 of the central core 2. In this case, the extension forms a longitudinal cavity 40 forming a groove or a housing whose width is substantially that of the longitudinal edge B _lon of the central core. According to another embodiment not shown, the longitudinal cavity 40 can be made of a solid material forming the central core 2. In the latter case, the groove 40 is machined in the mass of the material along the longitudinal edges of soul 2.

According to a preferred embodiment, the cavity between the two coatings projecting from the central core is used according to the invention to hold a channel profile 4 having a groove 40. According to an exemplary embodiment, the top coatings 3 participate in maintaining the profiles channel 4.

According to various embodiments, the groove 40 can be defined by a channel profile 4 or directly formed by an extension of two coatings 3. However, this solution requires sufficiently solid coatings. According to another example, a groove can be made directly in the material of the central core 2, in particular in the thickness of its side edges. In each embodiment, the space 40 is defined by a groove making it possible to embed therein at least one branch 300 of a connector 30.

Opposite faces

A panel P ₁ comprises a central core 2 comprising two opposite main faces F. These surfaces can be useful or simply decorative depending on the use of a panel P ₁ within a structure 100. These surfaces can also support various objects. , a panel P _{1 which} can act as a shelf.

According to one embodiment, a structure of the invention comprises panels of identical width within the same assembly forming a cabinet. On the other hand, the length of the panels can be adapted in order to obtain the desired configuration as shown in the example of figure 7 .

The faces of a central core 2 cooperate with the finishing coating faces 3. The coverings 3 are chosen and sized to cooperate with the central core 2. A bonding process can be used in order to fix the coating 3 on the. core 2, depending on the materials chosen. According to one embodiment, when a channel section 4 is arranged on the longitudinal edge of the central core, the surface of each covering 3 extends over the upper and lower faces of the channel section 4.

Longitudinal edges

A panel P _i of the invention comprises two longitudinal edges B _lon and two lateral edges B _lat . The right side edge B _ilad , the left side edge B _ilag , the right longitudinal edge B _ilod and the left longitudinal edge B _ilog of a panel P _{i are called} . When edges are mentioned in general, the B _lat and B _lon convention is used.

The designation of the side edges B _lat a panel P _i and a core 2 can be confused in the description to the extent that the side edge of the P _i B _lat panel and the edge of the core 2 may be substantially identical up to the coating thickness.

Likewise, the designation of the longitudinal edges B _lon of the panel P _i and of the core 2 can be confused when the longitudinal groove is generated directly in the edge of the material.

The longitudinal edges B _lon ensure the interconnection of the panels P _i by means of connectors 30. In addition, each longitudinal edge B _lon is designed, according to one embodiment, to receive a channel profile 4 and hold it. The longitudinal edge B _lon and the channel profile 4 form a visible part of the panel Pi or of a structure ST _i of the invention which can be covered by a finishing profile 10 or 10 '. The figure 1 shows a sectional view of two longitudinal edges B _lon which integrate two profiles 4.

A panel P _i of the invention is notably characterized by the design symmetry of its two longitudinal edges B _lon according to the plane OYZ shown in figure 1 . Each longitudinal edge B _lon comprises a groove 40 produced, for example, by embedding a channel profile 4 in the edge of a panel P _i . This symmetry, according to the OYZ plane represented on the figure 1 , in particular allows increased modularity and greater flexibility in the use of a structure ST ₁ of the invention.

Side edges

The final shape of a lateral edge B _lat of a panel P ₁ can be produced by machining the lateral edge of the central core 2. The geometry of the cuts of each lateral edge B _lat is called “radial”. It makes it possible to make different side edges of a plurality of panels P _i coincide according to the configuration envisaged in order to produce a structure ST ₁ of the invention. The lateral edges B _lat panels are thus destined to meet to form the junctions 50, such as that shown in figure 3 .

The figures 8A to 8D represent different structures ST ₁ of the invention in which the lateral edges B _lat, at certain junctions 50 have complementary radial sections whose angles may vary depending on the number of panels involved and their orientation. The angle defines the inclination of the plane of a radial section relative to the longitudinal plane of a panel. It is generally between 30 ° and 120 °. When there is only one radial cut, the range of angles of the radial cuts is preferably between 30 ° and 85 ° and / or 95 ° and 120 °.

According to a very conventional configuration, the lateral edges B _lat at certain junctions 50 comprise two radial sections, the first angle of the first section is 45 ° and the second angle of the second section is 90 ° to form junctions at right angles between the panels of a classic-shaped piece of furniture, such as the one shown in figure 8A or the figure 9 .

• ▪ un premier panneau P₁ comportant sur un de ses bords B_lat une première coupe radiale formant un premier angle β₁ = 45° et une seconde coupe radiale formant un angle β₂ = 90°,
• ▪ un second panneau P₂ comportant, sur un de ses bords B_lat, une première coupe radiale formant un angle β₁ = 45° et une seconde coupe radiale formant un angle β₂ = 90°, la seconde coupe radiale du second panneau P₂ coopérant en formant un contact plan avec la seconde coupe radiale du premier panneau P₁ ;
• ▪ un troisième panneau P₃ comportant, sur un de ses bords B_lat, une première coupe radiale formant un angle β₁ = 45° et une seconde coupe radiale formant un angle β₂ = 45°, chacune des première et seconde coupe radiale du troisième panneau P₃ coopérant en formant des contacts plans avec respectivement la première coupe radiale du premier panneau P₁ et la première coupe radiale du second panneau P₂.

The figure 9 represents, in fact, an example of an embodiment with:

• ▪ a first panel P ₁ comprising on one of its edges B _lat a first radial section forming a first angle β ₁ = 45 ° and a second radial section forming an angle β ₂ = 90 °,
• ▪ a second panel P ₂ comprising, on one of its edges B _lat , a first radial section forming an angle β ₁ = 45 ° and a second radial section forming an angle β ₂ = 90 °, the second radial section of the second panel P ₂ cooperating by forming a plane contact with the second radial section of the first panel P ₁ ;
• ▪ a third panel P ₃ comprising, on one of its edges B _lat , a first radial section forming an angle β ₁ = 45 ° and a second radial section forming an angle β ₂ = 45 °, each of the first and second radial section of the third panel P ₃ cooperating by forming plane contacts with respectively the first radial section of the first panel P ₁ and the first radial section of the second panel P ₂ .

According to an embodiment, the ST structures ₁ of the invention are especially characterized by a symmetry of the two lateral edges B _lat a panel P _i which are shaped by a similar machining method. This design symmetry notably allows increased modularity and greater flexibility in the use of the structures ST ₁ of the invention.

Channel profile

The channel profile 4 embedded in a longitudinal edge B _lon preferably forms a groove 40 open towards the outside in order to accommodate a branch of a connector 30. According to one embodiment of the channel profile 4, the geometry of the edge opposite the groove is provided to cooperate with the longitudinal edge B _lon of the central core 2.

In addition, it includes a lower extension and an opposing upper extension, forming the walls of the groove. According to various embodiments, the channel profile 4 forms a cavity allowing the passage of technical equipment such as cables.

When it is covered for example by a finishing profile 10, the groove 40 can also be considered as a longitudinal gallery. The width of the groove 40 is substantially equal to the distance between the two coatings 3, minus the thickness of the walls of the profile. The channel profile 4 is therefore held between the overhangs of the finishing coatings 3.

The cavity 40 designates the space obtained and usable at the level of the longitudinal edges B _lon of a panel P ₁ of the invention.

According to one embodiment, the channel profile 4 has an outer surface in contact with the coverings 3, provided to allow their connection by gluing.

According to a preferred embodiment, each longitudinal edge B _lon of the central core 2 is machined so as to generate a longitudinal tenon 9 forming a protrusion and making it possible to embed the side opposite the groove 40 of the channel profile 4. According to one method of embodiment, the channel section 4 comprises a longitudinal mortise 8 making it possible to receive the longitudinal tenon 9 of the central core 2. An advantage of this assembly is to strengthen the retention of the channel section 4 at the ends of the longitudinal edges of the central core 2 particularly in demand. Thus, the connection {tenon 9 - mortise 8} ensures precise centering and prevents the displacement of the channel section of the channel section 4 relative to the central web 2 along the axis OZ. According to one embodiment, the finishing coatings 3 help to ensure the centering and maintenance of the channel profile 4 along the axis OZ.

Preferably, each channel section 4 is made of a metallic material. The central core 2 is preferably made of wood. The connection {tenon 9 - mortise 8} ensures a lasting bond between two different materials.

According to an exemplary embodiment, the section of the channel profile 4 is substantially "U" or "H" shaped. According to other exemplary embodiments, the section of the channel section 4 can be slightly optimized and include grooves or projections to provide various additional functions.

According to one embodiment, the channel profile 4 comprises means for holding 41 a finishing profile 10, 10 '. These retaining means 41 can be produced, for example by a groove in the internal faces of the walls of the groove 40 making it possible to retain a notch formed in a tab of the finishing profile 10, 10 '.

According to one embodiment, the channel section 4 comprises a longitudinal internal groove 42, visible in particular on the figure 2 , extending at least over a portion of the length of the channel section 4. The longitudinal internal groove 42 may be designed to receive a portion of a connector 30 as shown in FIG. figure 5 . The longitudinal internal groove 42 operates as a guide in which an arm of a connector is held. During assembly or disassembly of an assembly, the connectors 30 are inserted or withdrawn following the direction of the internal longitudinal grooves 42.

According to an exemplary embodiment, the portion of the connector 30 inserted in a groove 40 is a branch 300. A connector 30 comprises a plurality of branches 300. Each longitudinal edge B _lon of panel P _i concurrently at a junction 50, receives a branch 300 of a connector 30 so as to position and connect the radial sections of the lateral edges B of the P _lat panels about the central axis 15 of the junction 50.

The figure 4 represents a three-dimensional view of a junction 50 of four panels P _i . The assembly of the panels P _i is noted 100 on the figure 4 . More generally in the description, any assembly of panels is noted ST ₁ . It is understood that the radial sections 20 cooperate by plane contacts between adjacent panels P ₁ , P ₂ . Moreover, on this figure 4 are shown two finishing profiles 10 clipped onto the longitudinal edges B _lon of two panels P ₁ , P ₂ . The positioning and maintenance of the finishing profiles 10 are possible thanks to the channel profiles 4 embedded in the panels.

• ▪ La consolidation des tranches de panneaux, pouvant être soumises aux chocs. Le profilé canal 4, lorsqu'il est réalisé par exemple en métal renforce les bords d'un panneau P₁.
• ▪ L'amélioration de la résistance à la flexion des panneaux. Les profilés 4 sont placés le long des bords longitudinaux d'une âme centrale 2, augmentant la résistance mécanique de la structure, particulièrement en flexion.
• ▪ Servir de logement solide aux pièces mécaniques de liaison. Comme cela est décrit ci-après, les rainures 40 formées par les profilés 4 permettent de recevoir des éléments de liaisons, appelés connecteurs, permettant d'assembler une pluralité de panneau P₁ entre eux.
• ▪ Servir de canal technique pour un éventuel passage de gaines, câbles, fibres, etc. Les rainures 40 peuvent être conçues pour permettre le passage masqué d'éléments techniques. Cette fonctionnalité est particulièrement avantageuse en ce qui concerne l'apparence esthétique des meubles. D'autre part, en limitant l'accès au câblage, cela présente un intérêt pour la sécurité et la durabilité de l'installation.
• ▪ Permettre le maintien d'un profilé de finition 10, 10' comme représenté sur la figure 2.

Each channel section 40 is embedded in a longitudinal edge of a panel P ₁ thus providing several functions. Among these functions, we find:

• ▪ Consolidation of panel slices, which may be subjected to shocks. The channel profile 4, when it is made for example of metal, reinforces the edges of a panel P ₁ .
• ▪ Improving the bending resistance of the panels. The profiles 4 are placed along the longitudinal edges of a central core 2, increasing the mechanical strength of the structure, particularly in bending.
• ▪ Serve as a solid housing for the mechanical connecting parts. As described below, the grooves 40 formed by the profiles 4 make it possible to receive connecting elements, called connectors, making it possible to assemble a plurality of panels P ₁ together.
• ▪ Serve as a technical channel for a possible passage of sheaths, cables, fibers, etc. The grooves 40 can be designed to allow the hidden passage of technical elements. This feature is particularly advantageous when it comes to the aesthetic appearance of furniture. On the other hand, by limiting access to the wiring, this is of interest for the safety and durability of the installation.
• ▪ Allow the maintenance of a finishing profile 10, 10 'as shown in the figure 2 .

According to one embodiment, when sheaths and / or cables 20, 21 are inserted into a channel profile 4, a clamping element using a groove 42 can be integrated into the channel profile 4 to hold them in place. square.

In addition, a retaining element 11 can be used in order to facilitate the assembly of the connectors and the positioning of the finishing profile without hindrance by preventing accidental pinching of the cables.

Finishing profile

According to one embodiment, a finishing profile 10, 10 'as shown in figure 2 provides a decorative function, closing the channel and protecting against impacts. It helps to improve the aesthetics of the visible parts of the structure produced. It can be declined in different forms.

According to one embodiment, the finishing profile 10, 10 'comprises a rounded external shape extending the curvature formed by the external surface of the finishing coatings 3.

According to one embodiment, the finishing profile 10, 10 'receives a surface treatment. The finishing profile 10, 10 'can be made of metal, for example aluminum, plastic, elastomer or wood depending on the criteria of style and finish of the furniture produced.

According to different configurations, the finishing profile 10, 10 'has the dimension adapted to the thickness of the central core 2 of the panel P ₁ , that is to say the distance separating the two finishing coatings 3 on the side on the other side of the central core 2. Its thickness may be between a few millimeters and several centimeters.

Structures, radial section

The structures ST _{1 are} obtained by making several panels P _i cooperate at the level of the junctions 50. The structures ST ₁ obtained are generally, from a geometric point of view, a set of right prisms. interconnected. A structure ST ₁ is an assembly of panels {P _l } _{iε [1; N]} . We can then speak indifferently of structure or assembly. The invention allows, in addition to the production of conventional structures composed of orthogonal panels, the creation of structures of more or less complex irregular shape.

The figure 3 50 shows a junction of the lateral edges B _lat four orthogonal panels exploded view. The central axis 15 of the junction 50 is the meeting line of the radial sections of each panel which will be assembled. It will be recalled that a lateral edge of panel B _lat is perpendicular to an edge of longitudinal panel B _lon . In a panel junction 50, each side edge B _lat of the panel is machined so as to generate a flat surface allowing the contacting of contiguous panels at their bisecting plane. In the example of figure 3 , four plane contacts provide the junction between four panels P _i which will then be joined together by connectors 30. In a two-dimensional representation of a junction 50, the central axes 15 of the panels P _i are concurrent at a point defining the geometric center of l 'assembly, around which radiate the cutting lines, which are the bisectors between adjacent panels.

According to one embodiment, each panel P _i has two radial sections of a certain angle depending on the assembly that is to be produced. According to one example, the radial section 20 is extended beyond the coverings 3 so that the panels cooperate over the entire surface of their lateral edge B _lat . This makes it possible in particular to offer a good finish to the corners of the assembly.

In this embodiment with two radial sections per panel, it is understood that the angles of the two radial sections cannot both be equal to 90 °. Indeed, this case amounts to considering a case where the two radial sections are merged.

The radial cuts 20 make it possible to form a plane contact between the panels P _i of an assembly over the entire length of their lateral edge B _lat . According to one embodiment, the sum of the angles formed by the lateral ends of the panels assembled together in a junction 50 is substantially equal to 360 °. According to an exemplary embodiment, the contacting surfaces of two adjacent panels can be glued to fix the connection of the junction 50. In the latter case, the assembly would no longer be removable.

Assembly of structures, connector

An advantage of the channel profiles 4 embedded in the panels P _i is to provide a housing for inserting the branches of a connector 30 at least partially. The connectors 30 make it possible to maintain a structure comprising several panels Pi assembled together.

According to one embodiment, each connector 30 comprises a set of “branches” of identical geometry. The branches 300 radiate around the central point of the connector 30. According to other specific variants, the shape and the dimensions of the branches 300 of the same connector 30 may differ from one another to meet particular constraints. In what follows, we consider the usual case in which the branches 300 are all identical for the same connector 30.

The shape of the connector 30 is designed to allow it to be housed precisely in the grooves of the panels P _i , by insertion. According to one example, this insertion can be done inside the metal profiles 4.

The figure 5 shows examples of connectors 30 for different panel junctions. A connector 30 comprises a plurality of branches 300 and possibly openings 35 for the passage of screws 36 to fix and position the connectors 30 to the panel.

On the figure 5 , an example of a connector 30 comprising 3 branches and denoted 31. This connector 31 can be used for junctions 50 between three panels P _i . A structure comprising junctions with three panels P _i is shown in the figure 8B .

The example of figure 8B shows a honeycomb structure comprising, among others, junctions 50 making three panels P ₁ cooperate angularly offset by 120 °. In this example, a connector 30 comprising 3 branches can be used, the angle between two adjacent branches being in this case 120 °.

A second example of a connector 30 comprising 4 branches is shown on figure 5 . This embodiment is denoted 32. In this case, the angles between two adjacent branches 300 are equal and make 90 °. Thus, in the example of connector 32, two adjacent branches 300 form an angle of 90 °. The assembly of the figure 8C comprises junctions 50 of orthogonal panels in which connectors of this type are used.
The figure 7 shows an alternative embodiment of a structure comprising a junction 50 provided by a connector 30 with four branches. In this particular design case, the connector 30 comprises four branches, the angular offset of which is not regular. The side edges of the four concurrent panels are shaped by radial cuts oriented along the bisecting plane between adjacent panels. In other words, the angle of a radial section 20 with respect to the plane of the panel is equivalent to half the angle between two adjacent panels, or between two branches of the corresponding connector.

A third example of a connector 30 comprising two branches 300 is shown on figure 5 . This embodiment is denoted 33. Such a connector 33 can be used to make junctions 51 between two panels P ₁ , P ₂ , representing the corners of a piece of furniture for example. This is the minimum assembly of panels P _i constituting a structure of the invention. They may be particular interior assemblies or assemblies of panels located on the periphery of a structure such as in the upper part of the cabinet 8D, having a junction 51 forming an elbow. Different angles between the two branches can define the orientation of two panels P ₁ , P ₂ assembled together. In the example of figure 5 , the connector 33 has a "V" shape. According to another example, it can define a right angle. In the latter case, when a connector 30 has an angle straight and two branches 300, it can join together two orthogonal panels whose lateral edges have a radial cut 20 to 45 °.

The example of figure 8D represents a piece of furniture of which the junctions 50 are of different natures. There are junctions 50 with three panels P ₁ , P ₂ , P ₃ , assembled using a connector 30 with three branches, for example of type 31, and other junctions 50 requiring connectors 30 with two or even four branches 300 Thus, the invention allows different types of panel junctions 50 in order to produce modular structures. This possibility grants the user of the invention great freedom of geometry in order to respond to the most varied projects.

The connectors 30 of a panel structure 1 ensure a solid and reversible assembly allowing the assembly and disassembly of said structure ST ₁ . The strength of an assembly is notably ensured by connectors 30 arranged symmetrically on either side of each longitudinal edge B _lon of a panel. Thus, by construction, a structure ST ₁ of the invention has fixing elements, such as connectors 30, arranged symmetrically along the Oyz plane. This arrangement improves the resistance to the stresses applied to the structure of the invention. Another advantage of the arrangement of the connectors on either side of each longitudinal edge is that of reducing the amount of material used to connect two panels. Consequently, this solution makes it possible to reduce the mass of the structure while guaranteeing the mechanical strength of said structure.

According to an exemplary embodiment, a connector 30 is made in one piece, preferably in a metal alloy or in another material of sufficient mechanical strength. In one embodiment, each connector 30 is made in one piece, preferably in a metal alloy or in another material of sufficient mechanical strength.

According to one embodiment, on the axis of each branch 300, a drilling of a hole 35 allows the passage of a screw 36 to secure and positioning said connector 30 in the groove 40 of the longitudinal edge B _lon of the panel Pi.

The connectors 30 can be manufactured by molding, milling, punching, electroerosion, water jet cutting or even by other usual manufacturing methods. According to another mode of manufacture, the connectors 30 can be cut with a laser from a sheet. The laser beam cuts the contours of the part from a plane.

This process allows production on demand, by project, of lots of connectors of various shapes. This mode of production has the advantage of being particularly suited to the production of parts to form structures of the invention.

Assembly method, connector

The figure 6 represents a step in the assembly of a junction of four panels P ₁ , P ₂ , P ₃ , P ₄ . Each branch 300 of a connector 30, 32 is inserted into a groove 40 of a channel section 4 fixed to a longitudinal edge of a central core 2.

According to one assembly mode, the installation of a connector 30 can be achieved by inserting said element into the groove 40.

The assembly may include a step aimed at precisely positioning and maintaining each branch 300 of each connector 30 in the groove 40 of a panel P _i . To this end, according to one embodiment, the connector 30 may comprise openings 35 for the passage of screws 36. The screws 36 are then inserted, for example, in the base of the groove 40 of a channel profile 4 then in the edge of the central core 2 which can be made of wood.

Applications, improvements

The assemblies 100 obtained forming structures of the invention can be associated with various possible improvements.

In particular, it is possible to insert a bottom panel into the compartments of a structure ST ₁ , for example to partition, but also to increase the rigidity of the assembly.

A structure ST ₁ of the invention is also compatible with a door for partitioning, for example, a compartment of a piece of furniture. By way of example, the channel profile 4 or the finishing profile 10, 10 ′ may comprise means allowing the opening and closing of a door.

• des éléments d'organisation et de présentation pour objets entreposés ;
• des systèmes d'éclairage intégré;
• des systèmes électroniques par exemple pour créer du mobilier connecté.
• etc.

In addition, the structures of the invention which form compartments can be equipped with intermediate shelves, drawers, storage accessories and other very diverse equipment, such as:

• organization and presentation elements for stored objects;
• integrated lighting systems;
• electronic systems for example to create connected furniture.
• etc.

Manufacturing process of a panel

Finally, the invention relates to a method of manufacturing a panel P _i . The manufacturing process comprises shaping a central core 2. The central core 2 can be made, for example, of wood, plastic, metal, or some other material. Shaping comprises a first machining of the lateral edges B _lat to form radial cuts 20.

The shaping comprises an optional second machining of the longitudinal edges B _lon to form a longitudinal tenon 9 to hold a channel profile 4. Other systems for fixing a channel profile 4 can be envisaged, an alternative consisting of machining a groove rather than 'a tenon.

The manufacturing process comprises the installation, for example by embedding and / or by gluing, of a longitudinal channel profile 4 along the longitudinal edge of the central core 2. This step is carried out on each longitudinal edge of the central core. 2.

The manufacturing process comprises the application of two coatings 3 on each of the opposite faces F of the central core 2. A bonding of the coatings 3 on the central core and the channel profiles 4 can be carried out in order to secure the assembly and get a sandwich structure. The sandwich structure defining a panel P _i comprising the two coverings 3 and the central core 2. The coverings 3 are designed to protrude beyond the two longitudinal edges B _lon of the central core 2. The process comprises bonding the coverings 3 on the channel profiles 4 on each side of the Pi panel.

• la pose du profilé canal 4 par encastrement dans la cavité formée par les revêtements de finition 3 ou ;
• la pose des revêtements 3 sur chaque face F de l'âme centrale 2 et sur les faces extérieures du profilé canal 4 préalablement mis en position.

The manufacturing process may alternatively include:

• the installation of the channel profile 4 by embedding in the cavity formed by the finishing coatings 3 or;
• the laying of coverings 3 on each face F of the central core 2 and on the outer faces of the channel profile 4 previously placed in position.

Finally, the manufacturing process may include a step of pressing the coatings 3 onto the central core 2.
