Description

Art furniture with three-dimensional elements and integrated lighting

  The invention relates to decorative furniture with integrated lighting, and more particularly to a decorative table with a transparent tray carried by a box in which is visible a decorative pattern the box comprising a system of proximity lighting for a value of the visual perception of this decorative pattern.

  In the application considered above, the decorative table must have a box high enough to delimit a closed and accessible space in which a decorative object can be placed at its convenience in the vicinity of which is an additional radiation effect lighting Proximity. This complementary illumination power supply battery or low voltage sector is evenly distributed around the perimeter of the decor to highlight and can be in the form of different light sources point or not such as neon-type lamps, bulb or light-emitting diode LED.

  On the other hand, the lighting system is confined so that it is not directly visible from the outside.

  The problem of highlighting a two-dimensional image or signage in a table has already been considered in the past, in particular in advertising promotion as illustrated in particular in the patent FR 2 276 649. for rectangular or circular tables in hotels or breweries. This document describes a piece of furniture with a mobile transparent tray to permanently leave in public view in the rooms or terraces a simple poster advertising presentation that can be easily exchanged for a new advertising campaign.

  Similarly, WO 96/37127 discloses a transparent tray table under which is disposed a sheet-shaped advertising medium.

  Many other documents such as WO 97/32503 or US 6 739 271 describe a table with a transparent panel having a space for carrying a visible advertising element and whose accessibility is greatly facilitated by a removable portion. It is essentially interchangeable means to easily replace a decorative panel in two dimensions.

  US 4 120 248 discloses a transparent circular table under which a star-shaped volume is arranged. In the volume are provided illumination lamps and a lighting control system.

  Another document FR 2,200,796 describes luminous decorative panels which, perforated and rotated, make it possible to diffuse various light effects in the environment.

  Similarly, WO 86/04493 describes a lighting source in the center of a table to promote the vision of an ornamental element.

  In these different embodiments, the lighting system is located below an element to be visualized and the desired decorative effect is none other than the appearance of a colored light beam or the underlining of the particular outline of a light. two-dimensional motif represented on a transparent or translucent support on the top of

Table.

  Moreover, WO 02/077953 discloses a retractable transparent circular or rectangular tray table in which is placed a flat luminous screen forming light signaling for any type of advertising or promotional information.

  In this case, the traffic sign consists of a particular illumination system which emits its own light in order to perceive the graphic information itself to be communicated.

  If this embodiment has a certain originality by its emission of artificial light, it provides only better visibility by backlighting a two-dimensional element. The sign better captures the attention of the observer on the message to be transmitted.

  US 5,536,558 discloses an interaction between the light emitted by a source with a light guide material to form decorative signage by light refraction effects that grooves on the material accentuate.

  An object of the invention is to provide a table of this type having an interaction between the lighting system and the decorative pattern placed in the box, for a pronounced aesthetic effect that contributes to generating a particularly lively atmosphere.

  The invention relates to a decorative table with integrated lighting, comprising a box whose top is formed by a transparent plate, the bottom of the box carrying a decorative pattern, a lighting system being disposed internally and laterally along the sides of the box, characterized in that the decorative pattern is in three dimensions, the side illumination system highlighting the relief of the pattern.

  Advantageously, the decorative pattern carries on its surface optically active elements, reflecting or capturing and diffusing the light received from the lateral illumination system.

  These optically active elements can be obtained very differently on a three-dimensional surface.

  Special coatings such as so-called special effect paints used for automobile bodywork may be mentioned. Metal, aluminum or mother-of-pearl particles are included in the substrate and cause colored optical phenomena that vary according to the position of the observer in space.

  This principle can therefore be transposed onto an artistic work in three dimensions and make it possible to enhance the decor by the effects of light on optically active components.

  The three-dimensional surface can be obtained by any type of industrial or artisanal processes in combination with complementary operations of machine machining or manual shaping. For example, the decor may be formed by thermoforming a sheet of transparent plastic PMMA type on which a decorative pattern is machined by numerical control before or after deformation of the support in three dimensions.

  Also, the optically active elements can be glued to the surface of the three-dimensional decorative pattern.

  Advantageously, the optically active elements consist of silica grains, blades or cylinders of transparent or translucent plastic material or any other type of elementary component having properties favorable to the desired optical reactions of the light from any geometrical shapes multifaceted simple or complex.

  Preferably, the illumination system is constituted by an array of light-emitting diodes near the three-dimensional decor, preferably grazing.

  Other features are apparent from the following description made with reference to the accompanying drawings in which: Figure 1 shows a decorative table according to a first embodiment of the invention, Figure 2 shows a perspective view of a decorative pattern in three dimensions whose surface is provided with grains of sand, FIG. 3 represents a perspective view of another three-dimensional decorative pattern whose surface is made by the random association of translucent plastic lamellae and optionally tinted in the mass.

  In FIG. 1, the table according to the invention comprises a box 1 of generally circular, square or rectangular shape, having a flat bottom 2 and side walls 3, 4, 5, 6, so as to delimit a volume capable of receiving a decorative pattern in three dimensions. The box 1 is covered by a cover 7 consisting of a frame 8 at least partially covering the lateral faces 3-6 of the box 1, and a transparent top plate 9.

  In the vicinity of the plate, the lateral faces 3-6 of the box carry a network of illumination lamps of the interior volume of the box. These lamps are for example light-emitting diodes 10 advantageously supplied by a battery or a transformer on the low-voltage sector.

  Alternatively, the lamps can be mounted inside the frame 7, under the transparent plate 9.

  On the bottom 2 of the box 1, is arranged a decorative pattern in three dimensions such as those shown in Figures 2 and 3.

  In Figure 2, the decorative pattern represents a landscape of dunes machined in an extruded foam block, thermoformed in a plastic sheet or cast with resin, whose surface is advantageously covered with grains of silica or flakes that capture the light emitted from electroluminescent diodes and diffuse it in all directions of space by refractions and / or successive reflections.

  In Figure 3, the three-dimensional decorative pattern carries, glued to its surface, or taken by their base in the mass of the pattern, lamellae of translucent or transparent plastic possibly colored.

  These lamellae have a certain thickness, are preferably of tapered shape from the base to the end, and have a truncated rather than pointed end. The aim is to create as many light-collecting facets as possible, through optical refraction phenomena of the light in the material due to the refractive index change between the air and the material. vision of the relief.

  The cross section of the slats is substantially rectangular in shape. The slats have planar lateral and end faces. The slats are not all in the same position relative to the three-dimensional decorative pattern, but have different inclinations, which accentuates the decorative effect in three dimensions.

  The invention is not limited to the examples described but covers the technical equivalents.

  Art furniture means all types of interior and exterior furniture products and all applications derived from decoration such as wall-mounted paintings, as well as any personal or professional equipment that contributes to creating a special atmosphere in a closed or open space.

  In domestic or urban areas, applications may cover, for example, a bar, a door, a floor or a ceiling, a billboard or a luminous sign.

  The applications are not limited to this furniture and decorating business and may be expanded from the use of this invention.
