ELECTRICALLY CONDUCTIVE FINISHING PROFILE

Technical area

The present invention relates to the field of finishing profiles, in particular of baseboards, moldings or picture rails, which are electrically conductive and suitable for receiving and being electrically connected at least with electric dipoles, such as for example electric dipoles comprising one or more lighting elements or one or more light sources, and in particular light-emitting diodes. The invention finds mainly, but not exclusively, its application to the production of luminous decorative finishing profiles.

Prior art

In the field of interior decoration, in order to improve the aesthetics of the junctions between a wall and a floor or floor covering, it is usual to use finishing profiles with plinth function. In the same way, in order to improve the aesthetics of the junctions between a wall and a ceiling, it is usual to use finishing profiles making it possible to produce decorative ceiling moldings. Finally, it is also usual to use finishing profiles to produce decorative wall moldings, of the picture rails, and in particular picture rails called “chair” allowing to protect the wall from friction from the backs of chairs, and decorative picture rails, allowing an aesthetic transition between an upper wall part and a lower wall part, the lower and upper wall parts possibly being covered with different wall coverings.

For purely decorative reasons, the visible face of the finishing profile can be flat or have a more or less complex curved aesthetic profile, and the finishing profile can thus have a more or less simple or complex geometry in cross section.

detailed description

FIG. 1 shows a first alternative embodiment of an electrically conductive finishing profile 1 A, with plinth function, which is in accordance with the invention and which is provided with a plurality of electric dipoles 5A each comprising a light emitting diode 52.

With reference to FIGS. 1 to 3, the electrically conductive finishing profile 1A comprises a base profile 2A, of longitudinal axis A, made of one or more electrically insulating materials, a linear multilayer element 3A electrically conducting, and in this variant a 4A film produced in one or more electrically insulating materials.

The geometry in cross section and the dimensions of the base profile are irrelevant to the invention.

In this variant, the base section 2A is a rigid monobloc linear piece, which can for example be made of wood or the like, or of plastic, in particular PVC or the like. This profile 2A can for example be obtained by machining a bar or by extrusion. .

In the context of the invention, this base section 2A is not necessarily a single piece, but can for example be obtained by assembling, and in particular gluing, two or more pieces. The base profile can also be a breakable profile or separable into several parts.

In this particular alternative embodiment of FIGS. 1 to 3, the base section 2A has on the rear face 21 (FIG. 3) a longitudinal rear recess 21a in the form of L and adapted to serve as housing for the electrically conductive multilayer linear element 3A (figure 4).

More particularly, in this variant, the front vertical wall 20a on the front face 20 of the base profile 2A ends in an upper longitudinal edge 20b comprising on the rear face a longitudinal recess 20c, intended to serve as an upward locking stop for the linear element 3A.

The multilayer linear element 3A consists of a multilayer complex in the form of a bar with a quadrangular cross section, and comprises two electrically conductive layers 30, 31 which are arranged opposite one another, and three layers 32, 33, 34 electrically insulating, namely: an internal layer 32, which is interposed ίο between the two electrically conductive layers 30, 31, an external lower layer 33 which is positioned against and covers the lower face of the lower conductive layer 31 , and an outer upper layer 34 which is positioned against and covers the upper face of the upper conductive layer 30. Thus in this embodiment, each conductive layer 30, 31 is sandwiched between two insulating layers 32/33 or 32/34.

Each insulating layer 32, 33, 34 is made of one or more electrically insulating materials, and preferably has a punching hardness (without removal of material) lower than that of the base profile.

More particularly the punching hardness (without removal of material) of the insulating layers 32, 33, 34 is sufficiently low to allow penetration of penetrating elements by punching without removal of material or by screwing, and preferably by punching or screwing to the hand, such as for example the pins 50, 51 of an electric dipole 5A comprising at least one light-emitting diode 52, the pins 50, 51 respectively fulfilling the cathode and anode functions of the light-emitting diode 52.

By way of nonlimiting and nonexhaustive examples of the invention, the insulating material of the layers 32, 33, 34 can be a foam, and in particular a polyurethane foam. The insulating material of the layers 32, 33, 34 can consist of any type of polymer or mixtures of polymers. For example, the insulating material of the layers 32, 33, 34 can be made of polystyrene. The insulating material of the layers 32, 33, 34 can also be a woven or nonwoven fibrous material.

Each electrically conductive layer 30, 31 preferably has a sufficiently small thickness to be able to be crossed by punching or screwing, and preferably by punching by hand, by penetrating elements, such as for example the pins 50, 51 of an electric dipole. 5A.

Each electrically conductive layer 30, 31 can be made of any material having sufficient electrical conductivity to transmit electrical signals from one end of the conductive layer to the other. Each layer 30, 31 is for example a metal layer, produced for example in the form of a metal film or a thin metal plate. Each layer 30, 31 can also be produced in the form of a sheet of conductive fibers, of a conductive grid, of a conductive mesh, of a conductive mesh or of a sheet of expanded metal.

The electrically conductive multilayer linear elements 3A can for example be obtained by cutting out a multilayer complex of larger surface area.

With reference to FIG. 4, the base profile 2A and the multilayer linear element 3A are assembled together, for example by gluing, by positioning the linear element in the L-shaped rear recess 21a of the base profile 2A, so that the electrically conductive layers 30, 31 of the multilayer linear element 3A extend longitudinally in the direction of the length of the base profile 2A.

With reference to FIG. 2, the rear face 21 of the base profile 2A of the finishing profile 1A as a function of the plinth defines a laying plane P, and the base profile 2A is fixed on the rear face in this laying plane P against a wall M, such as a wall so as to allow an aesthetic connection between this wall M and the ground S. In this variant, the electrically conductive layers 30 and 31 are substantially perpendicular to said rear laying plane P of the base profile 2A .

In this variant of FIG. 4, the multilayer linear element 3A is positioned behind the front face 20 of the base profile 2A, and more particularly the front face 20 of the base profile partially overlaps (flange 20b with rear offset 20c) l linear multilayer element 3A over its entire length.

In this variant of FIG. 4, the electrically conductive layers 30, 31 of the multilayer linear element 3A are visible only on the rear face 21 of the base profile 2A, only the rear longitudinal edge of these conductive layers 30, 31 being visible in back side.

Preferably in this variant, the electrically conductive layers 30, 31 of the multilayer linear element 3A extend longitudinally from one end to the other of the finishing profile 1A, that is to say over the entire length of this finishing profile. In another variant, the electrically conductive layers 30, 31 of the multilayer linear element 3A could extend longitudinally over only a portion of the length of the finishing profile 1A.

The decorative film 4A covers the front face 20 of the base profile 2A, the upper edge 20b of this base profile and the upper face 3a of the multilayer linear element 3A. The front face 20 of the base section 2A which is covered with the film 4A forms the front face of the plinth 1 A, that is to say the visible face of the plinth 1A when the plinth 1A is mounted between a wall M and a ground S (figure 2).

The film 4A is usually fixed to the base profile 2A and to the multilayer linear element 3A by any known means, and in particular by gluing and / or heat-bonding. This film 4A forms a coating which can be decorative and / or protective and / or anti-wear. It can for example be made of paper, melamine or wood veneer. It can be transparent, translucent or opaque. This film 4A can be of the monolayer or multilayer type. The film 4A can make it possible, for example, to match the plinth 1A to the decorations of a floor covering and / or a wall covering.

With reference to FIGS. 1 and 2, the finishing profile 1A is further provided with electric dipoles 5A which each comprise a light-emitting diode 52, and which have been fixed to the multilayer linear element 3A, being distributed in the direction of the length of the finishing profile 1 A.

Each light-emitting diode 52 comprises a first pointed electrically conductive pin 50 of short length, forming the cathode of diode 52 and a second electrically conductive pointed pin 51, of greater length and forming the anode of diode 52. The pin 51 forming the anode is also covered with an insulator 54 with the exception only of the tip 51a of the pin 51.

Each electric dipole 5A further comprises a depression 53, in the form in this example of a transverse wall with pins 50 and 51.

Each electric dipole 5A is fixed to the multilayer linear element 3A, so that in this variant, the diodes 52 are visible on the upper edge of the finishing profile 1 A.

The fixing to the multilayer linear element 3A of each electric dipole 5A is carried out by piercing the film 4A and the multilayer linear element 3A, by means of the anode 51 and the cathode 50 of the light-emitting diode 52, up to that the abutment stop 53 is applied against the multilayer linear element 3A and blocks in position the dipole 5A relative to the multilayer linear element 3A.

The length of pins 50 and 51 is adapted relative to the position in depth of the two conductive layers 30, 31 in the multilayer linear element 3A, so that once an electronic dipole 5A is inserted in the multilayer linear element 3A , until its abutment abutment 53 comes into abutment against the multilayer linear element 3A,

the tip 51a of the anode 51, devoid of insulation, is in electrical contact with the deepest conductive layer 30, and is insulated by the insulating coating 54 of the other conductive layer 31,

- the cathode 50 is in electrical contact with the shallow conductive layer 31 and is not in contact with the other conductive layer 30.

In the variant of FIG. 2, the anode 51 passes through the lower conductive layer 30 and enters the lower insulating layer 33 of the multilayer linear element 3A. In another variant, the anode 51 could be in contact with the conductive layer 30 without passing through it.

In another alternative embodiment, the multilayer linear element 3A could also be devoid of an upper insulating layer 34 and / or be devoid of a lower insulating layer 33.

When the layers 30 to 34 of the linear multilayer element 3A have a sufficiently low punch hardness to be able to be pierced by hand, the positioning of each dipole 5A can advantageously be carried out by manually exerting vertical pressure on the dipole 5A so as to manually pierce the different layers of the multilayer linear element 3A with the cathode 50 and the anode 51 of the diode 52. The establishment of the dipoles 5A can thus be carried out easily and very quickly, before or after putting into operation plinth place 1A against wall M.

In another variant, the electrical dipole could be adapted to be fixed by screwing through the multilayer linear element 3A.

In a variant, when the layers of the multilayer linear element 3A are too hard, it is possible in this case to make drilling holes for the passage of the cathode 50 and the anode by means of a drill or equivalent. 51 of the light-emitting diode 52.

By electrically supplying each conductive layer 30, 31 with current by means of an electric voltage applied between the two conductive layers 30, 31, all the light-emitting diodes 52 of the electrical dipoles 5A are electrically supplied with low current.

The invention is however not limited to a finishing profile 1A forming, by means of the conductive layers of its multilayer linear element, a low current network, but also extends to the production of a definition profile suitable for forming a strong current network by means of the conductive layers of its multilayer linear element.

Thanks to the invention, the positioning of each dipole 5A along the finishing profile 1A is very flexible, the dipoles 5A can be easily installed at any position along the multilayer linear element 3A; the spacings between 5A dipoles can also be equal or not, and can be chosen by the end user.

The installation of the dipoles 5A on the finishing profile 1A can also advantageously be carried out at the place of installation of the finishing profile 1A, and it is not necessary to carry out this installation in the factory.

Furthermore, thanks to the invention, it is very easy to replace a defective dipole with a new dipole or to replace a dipole 5A with diode 52 of a given color by a dipole 5A with diode 52 of another color, or still add 5A dipoles to diode 52 on the 1 A finishing profile.

Advantageously, the finishing profile 1A can also be used without a dipole, so that in a room or a corridor, one can select the finishing profiles 1A which will be bright by being equipped with 5A dipoles with diode 52.

In the variant of FIGS. 1 and 2, the upper face 3a of the multilayer linear element 3A is positioned at a lower level than the upper edge 20b of the front face 20 of the base profile 2A, so that the diodes 52 are hidden by the front face 20 of the base profile 2A, and are visible only on top of the finishing profile 1A, which improves the aesthetics of the limineuselA plinth.

In another variant, such as that illustrated for example in FIGS. 5 and 6, the front face 20 of the base section 2B may not mask the diodes 52.

In another variant, the multilayer linear element 3A may comprise more than two electrically conductive layers and insulated from one another by insulating layers, and in particular three or four electrically conductive layers making it possible respectively to equip a finishing profile with electrical tripoles or electrical quadrupoles, each pole of which is in electrical contact with one of the conductive layers of the multilayer linear element.

With reference to FIG. 7, another example of an electric dipole 5B has been shown allowing the electrical supply of the conductive layers 30 and 31 of a finishing profile of the invention. This electric dipole 5B constitutes an electrical supply connector and comprises a support 53, on which two supply pins 50 and 51 are fixed and which also serves as a stop for the insertion of the connector. The pins 50 and 51 of this connector 5B can be supplied electrically with direct current by means of a transformer 55 which can be inserted into a conventional electrical outlet, so for example that the pin 51 is supplied with a positive polarity (respectively negative) and pin 50 with reverse polarity. The two pins 50 and 51 allowing the fixing, on a finishing profile of the invention, and the electrical connection of this electrical dipole 5B with the conductive layers 30 and 31 of a multilayer linear element, in the same manner as previously described for dipole 5A of the variants of FIGS. 1 to 6.

FIG. 8 shows the finishing profile 1B on which the above-mentioned electric supply dipole 5B is fixed and a plurality of light electric dipoles 5A previously described.

FIG. 9 shows another example of a luminous electric dipole 5C which can be used with a finishing profile of the invention. This luminous electric dipole 5C comprises a strip 53 serving as a stop for the sinking and comprising several light-emitting diodes 52 connected in series. This luminous electric dipole 5C further comprises at each end two pins 50 and 51, which function respectively as cathode and anode and which allow the fixing, on a finishing profile of the invention, and the electrical connection of this electric dipole 5C luminous with the conductive layers 30 and 31 of a multilayer linear element, in the same manner as previously described for the dipole 5A of the variants of FIGS. 1 to 6.

FIG. 10 shows another example of an electrical dipole 5D forming an electrical connection jumper, which can be installed at the junction between two finishing profiles 1B positioned end to end in the extension of one another ( Figure 11), so as to electrically connect in series the lower conductive layer 30 of a profile 1B with the lower conductive layer 30 of the adjacent profile 1B, and to electrically connect in series the upper conductive layer 31 of a profile 1B with the upper conductive layer 31 of the adjacent profile 1B. This electrical connection jumper 5D comprises two pins 50 electrically connected to each other by an electrical conductor 56 and two pins 51 electrically connected by an electrical conductor 57.

There is shown in Figure 12, another example of electrical connection jumper 5E L-shaped and in Figure 13 another example of electrical connection jumper 5F L-shaped and further provided with light emitting diodes 52 in series. These electrical connection jumpers 5E or 5F can be used as an electrical connection between two finishing profiles 1B (FIG. 14) positioned end to end at an angle.

FIG. 15 shows another variant of finishing profile 1C according to the invention, in which the linear multilayer conductive element 3A is positioned and for example glued to the upper edge of a base profile 2C, and which has a 4C coating.

There is shown in FIG. 16, another variant of finishing profile 1D in accordance with the invention, in which the linear multilayer conductive element 3A is inserted in an upper longitudinal groove or groove 22 (FIG. 17) in the form of U d '' a basic 2D profile. This finishing profile 1D also includes a coating 4D which covers the conductive multilayer linear element 3A and closes the groove or groove in the upper longitudinal U-shape.

FIGS. 18 and 19 show another variant of finishing profile 1E according to the invention formed from a linear multilayer conductive element 3A and a base profile 2A, and without coating 4A unlike finishing profile 1A previously described.

There is shown in Figures 20 and 21, another variant of finishing profile 1F according to the invention. This finishing profile 1F is formed from a conductive multilayer linear element 3A and from a base profile 2F in two parts 23 and 24. The external part 23 of the base profile 2F is adapted to be fitted onto the internal part 24 of the base section 2F, which has been previously fixed to a wall M, for example by means of screws V.

There is shown in Figures 22 and 23, another variant of finishing profile 1G according to the invention. This finishing profile 1G is formed of a conductive multilayer linear element 3A and of a base profile 2G in two parts 25 and 26. The external part 25 of the base profile 2G is adapted to be fitted onto the internal part 26 of the 2G base profile, which has been previously fixed to an M wall.

FIGS. 25 and 26 show another alternative embodiment of a multilayer linear element 3B, which consists of a linear element 3 ′ of electrically insulating material and of two electrically conductive plates or strips 3 ”, for example metal.

The insulating linear element 3 ’comprising two longitudinal grooves or grooves 35 which are substantially parallel and which extend over the entire length of the linear element 3’. With reference to FIG. 25, the two 3 "conductive plates or strips are assembled with the insulating linear element 3’ by being fitted respectively into the grooves or longitudinal grooves 35 of the insulating linear element 3 ’. The two conductive plates or strips 3 ”form the two conductive layers 30 and 31 of the multilayer linear element 3B and the insulating layers 32, 33 and 34 of the multilayer linear element 3B are formed by the linear insulating element 3’.

FIG. 27 shows a finishing profile 11 with plinth function, in FIG. 29 a finishing profile 1J with plinth function, and in FIG. 31 a finishing profile 1K with plinth function, in which the electrically conductive layers 30 and 31 of the multilayer linear elements 3C or 3D are substantially parallel to the rear laying plane P of the base profile 2C or 2E. In these three variants, and unlike the previous variants, the light dipoles 5 are not fixed to the upper edge of the finishing profile, but are fixed to the front face of the finishing profile.

FIG. 32 shows a finishing profile 1L with the function of a light plinth on which dipoles 5A and 5C with light-emitting diodes 52 have been installed in this variant.

The finishing profile 1L comprises a base profile 2H of electrically insulating material in which two parallel longitudinal grooves R1 and R2 have been formed which extend in the direction of the length of the base profile 2H. In this variant, these two grooves R1, R2 open out into the front face of the base section 2H. This 2H base profile can be obtained by extrusion or machining.

The two grooves R1 and R2 respectively contain the two electrically conductive layers 30 and 31, and the base profile 2H is covered on the front face and on its edge with a coating 4C.

The two conductive layers 30 and 31 can for example be produced in the form of conductive strips or the like, for example of metal, inserted in the grooves, or in the form of a deposit of conductive material, for example of metal, produced in the two grooves R1 or R2. The base profile 2H integrating the two conductive layers 30 and 31 can also be produced by co-extrusion.
