Description

PAROI TRANSLUCIDE A COUCHE DE BOIS
La présente invention concerne une nouvelle structure de paroi translucide.
WOOD-LAYERED TRANSLUCENT WALL
The present invention relates to a new translucent wall structure.

De telles parois sont utilisées notamment dans le domaine de l'éclairage et de la décoration, pour produire par exemple des effets d'éclairage diffus, lorsqu'ils sont associés à des sources lumineuses. Such walls are used in particular in the field of lighting and decoration, to produce, for example, diffuse lighting effects, when they are associated with light sources.

La présente invention a plus précisément pour objet une nouvelle structure de paroi qui, en l'absence d'une source lumineuse, présente l'aspect d'un panneau de bois, et qui, éclairée par une source lumineuse disposée à l'arrière de la paroli, laisse apparaitre par transparence les dessins de la structure du bois et produit un éclairage de ton chaud. The present invention more specifically relates to a new wall structure which, in the absence of a light source, has the appearance of a wooden panel, and which, lit by a light source disposed at the rear of the paroli, lets appear through the drawings of the structure of the wood and produces a warm tone of lighting.

La difficulté résidait dans le fait que le bois n'est pas une matière particulièrement translucide, à moins de le découper en lamelles très fines ; et dans le cas d'une lamelle très fine, sa fragilite rend très difficile son utilisation industrielle et conduit à produire des objets dont la solidité est nettement insuffisante. The difficulty lay in the fact that wood is not a particularly translucent material, unless it is cut into very fine strips; and in the case of a very thin strip, its fragility makes it very difficult to use industrially and leads to the production of objects whose solidity is clearly insufficient.

Un objet de la présente invention est notamment d'éviter ces inconvénients en proposant une structure de paroi qui présente à la fois une translucidité suffisante pour les effets d'éclairage recherchés et une solidité suffisante pour les applications telles que l'éclairage et la décoration. An object of the present invention is in particular to avoid these drawbacks by proposing a wall structure which has both sufficient translucency for the desired lighting effects and sufficient solidity for applications such as lighting and decoration.

Un autre objet de l'invention est de proposer une telle structure dont la réalisation soit particulièrement simple et rapide, afin d'en permettre la production industrielle. Another object of the invention is to provide such a structure, the production of which is particularly simple and rapid, in order to allow industrial production.

Un autre objet de l'invention est de produire une telle structure qui soit suffisamment stable dans le temps, sans déformation, changement de teinte ou autre modification sensible des propriétés. Another object of the invention is to produce such a structure which is sufficiently stable over time, without deformation, change in color or other significant modification of the properties.

En outre, la présente invention permet de réaliser cette structure pour un coût faible, avec des composants peu onéreux, leur assemblage étant réalisé dans les conditions les plus faciles et automatisables. In addition, the present invention makes it possible to produce this structure at low cost, with inexpensive components, their assembly being carried out under the easiest and automatable conditions.

Pour atteindre ces objets ainsi que d'autres, la paroi translucide selon la présente invention comprend une fine feuille de bois de placage collée sur un support en une matière transparente ou translucide à l'aide d'une colle transparente. La qualité de collage est suffisante pour que le support en matière transparente assure la
résistance mécanique de l'ensemble, la feuille de bois étant maintenue
en forme par son support.
To achieve these and other objects, the translucent wall according to the present invention comprises a thin sheet of veneer wood glued to a support made of a transparent or translucent material using a transparent adhesive. The bonding quality is sufficient for the transparent material support to ensure the
mechanical resistance of the assembly, the wood sheet being maintained
shaped by its support.

Pour certaines applications, la feuille de bois est recouverte
d'un vernis transparent qui l'isole de l'atmosphère ambiante, et réduit
les risques de déformation dans le temps.
For some applications, the wood sheet is covered
a transparent varnish which isolates it from the ambient atmosphere, and reduces
the risks of deformation over time.

Pour les applications industrielles, il est nécessaire d'uti
liser un support transparent bon marché et d'emploi commode. Une matière
telle que le polymétacrylate de méthyle permet de réaliser un tel
support. Toutefois, la difficulté réside dans le collage de la feuille
de bois, collage qui doit être suffisamment stable dans le temps. Ce
collage doit en outre être facile d'emploi, ce qui exclut les colles
polymérisables. Malheureusement, il est bien connu que les colles
solvants présentent une résistance mécanique qui diminue sensiblement
dans le temps selon un facteur de un à dix. Cette faible résistance dans
le temps conduit à penser que ces colles ne sont pas utilisables pour
coller du bois, matière qui tend à présenter des propriétés variables
dans le temps.
For industrial applications it is necessary to use
read a transparent support inexpensive and convenient to use. Material
such as polymethyl methacrylate allows such a
support. However, the difficulty lies in gluing the sheet
of wood, bonding which must be sufficiently stable over time. This
bonding must also be easy to use, which excludes glues
polymerizable. Unfortunately, it is well known that glues
solvents have a mechanical resistance which decreases appreciably
over time by a factor of one to ten. This low resistance in
time leads us to think that these adhesives cannot be used for
sticking wood, a material that tends to have variable properties
in time.

Contrairement à cette attente, des essais de longue durée
effectués sur les essences de bois les plus courantes ont montré que le
collage d'une feuille suffisamment mince de bois, d'épaisseur inférieure
à un millimètre, sur un support en polymétacrylate de méthyle, par une
colle constituée d'un polymère de métacrylate de méthyle en solution
dans un solvant, présente une résistance suffisante pour les applica
tions visées. On constate en particulier que le bois ne tend pas à se
décoller ou à cloquer.
Contrary to this expectation, long-term trials
the most common types of wood have shown that the
sticking a sufficiently thin sheet of wood, of lesser thickness
to a millimeter, on a polymethyl methacrylate support, by a
glue made of a polymer of methyl methacrylate in solution
in a solvent, has sufficient resistance for applica
aimed at. We note in particular that the wood does not tend to
take off or blister.

D'autres objets, caractéristiques et avantages de la présente
invention, ressortiront de la description suivante d'un mode de
réalisation particulier, faite en relation avec la figure jointe
représentant une paroi selon l'invention associée à une source lumineu
se.
Other objects, features and advantages of this
invention will emerge from the following description of a mode of
particular realization, made in relation to the attached figure
representing a wall according to the invention associated with a light source
se.

Comme le représente la figure, la paroi translucide 1 comprend
une fine feuille de bois de placage 2 collée sur un support 3 en matière
transparente ou translucide.
As shown in the figure, the translucent wall 1 comprises
a thin sheet of veneer 2 glued to a support 3 of material
transparent or translucent.

Le support 3 est réalisé en polymetacrylate de méthyle, coulé
ou extrudé.
Support 3 is made of polymethyl methacrylate, cast
or extruded.

La feuille-de bois 2 est collée sur le support 3 au moyen wd'une colle solvant constituée d'un polymère de métacrylate de méthyle en solution dansun solvant. The sheet of wood 2 is glued to the support 3 by means of a solvent adhesive made up of a polymer of methyl methacrylate dissolved in a solvent.

I1 convient de choisir une feuille de bois en un bois relativement translucide, par exemple le sapin, le mélèze, le pin, le koto, le sycomore, le cerisier, le merisier. It is advisable to choose a sheet of wood in a relatively translucent wood, for example fir, larch, pine, koto, sycamore, cherry, cherry.

Le collage s'effectue en appliquant une couche de colle sur la face supérieure du support 3, puis en posant et en pressant sur la colle la feuille de bois 2. Une ou plusieurs couches de vernis 4 peuvent être appliquées sur la face extérieure de la feuille de bois 2. Le vernis peut être un vernis protecteur, par exemple vitrificateur ou autre. Bonding is carried out by applying a layer of glue on the upper face of the support 3, then by placing and pressing on the glue the sheet of wood 2. One or more layers of varnish 4 can be applied to the external face of the sheet of wood 2. The varnish can be a protective varnish, for example a glazing or other.

A l'utilisation, la paroi 1 peut constituer un panneau lumineux, disposé devant une source lumineuse 5. La source lumineuse 5 est disposée de préférence du côté du support 3, et la feuille de bois 2 ou le vernis 4 constitue la surface extérieure visible du panneau. In use, the wall 1 can constitute a light panel, placed in front of a light source 5. The light source 5 is preferably placed on the side of the support 3, and the sheet of wood 2 or the varnish 4 constitutes the visible external surface. of the panel.

La paroi 1 peut être plane, comme représenté sur la figure, ou courbe, permettant de réaliser des luminaires, des abats-gours.  The wall 1 can be flat, as shown in the figure, or curved, making it possible to produce luminaires, lampshades.

Les formes en paroi plane permettent de réaliser par exemple des planchers, plafonds, murs, bandeaux, plinthes, ou tous autres éléments utilisés en décoration de bâtiment. The flat wall shapes make it possible for example to produce floors, ceilings, walls, strips, plinths, or any other element used in building decoration.

ta présente invention n'est pas limitée aux modes de réalisa- tion qui ont eté explicitement décrits, mais elle en inclut les diverses variantes et généralisations contenues dans le domaine des revendications ci-après.  The present invention is not limited to the embodiments which have been explicitly described, but it includes the various variants and generalizations thereof contained in the field of claims below.
