Abstract

The panel for a door or piece of furniture etc. is built up from multiple veneer layers so as to give the effect of a thick, solid piece of wood. Parts of the sides of the composite panel are cut away, leaving a pyramid shaped central portion which is a decorative feature of this type of thick panel. A double sided design can also be formed. The veneer layers can be assembled in various combinations, with grain aligned in different directions, and certain layers made from the same wood. Those layers with the grain running at right angles to its main surfaces form up to 25 per cent, e.g. 10 per cent of the total thickness of the panel.

Description

L'invention concerne un panneau à plate-bande. The invention relates to a flower bed panel.

Les panneaux à plate-bande sont couramment utilisés comme panneaux de remplissage pour les portes et les cotés de meubles, les portes d'entrée, les portes de placards, etc... Flowerbed panels are commonly used as filler panels for doors and sides of furniture, entry doors, closet doors, etc.

Il est connu de fabriquer ces panneaux en usinant du bois massif de façon qu'il présente une ou deux parties saillantes (panneau double-face), le plus souvent de forme troncpyramidale, et une plate-bande entourant ces parties et servant au montage du panneau dans un cadre. It is known to manufacture these panels by machining solid wood so that it has one or two projecting parts (double-sided panel), most often of truncpyramidal shape, and a border surrounding these parts and used for mounting the panel in a frame.

Il est connu également de réaliser des panneaux par usinage de blocs de placages à fils parallèles repartis symétriquement par rapport au plan moyen du panneau, ce qui limite l'épaisseur des parties saillantes par rapport à celle de la plate-bande et impose des parties saillantes symétriques dans le cas d'un panneau double-face. It is also known to produce panels by machining veneer blocks with parallel wires distributed symmetrically with respect to the mean plane of the panel, which limits the thickness of the protruding parts relative to that of the bed and imposes protruding parts symmetrical in the case of a double-sided panel.

La présente invention vise à fournir un panneau à plate-bande constitué de plusieurs couches mais imitant le bois massif et affranchi des inconvénients et des limitations des panneaux connus en placages. The present invention aims to provide a flat panel consisting of several layers but imitating solid wood and freed from the drawbacks and limitations of known panels in veneers.

En fait, l'invention permet d'obtenir aussi les avantages suivants
- combinaisons de placages dans des épaisseurs pratiquement illimitées
- présentation possible sous forme de panneaux stables non usinés qui resteront stables et rigides après usinage
- matériau plus stable que le bois massif ;;
- matériau sec (humidité proche de l'humidité d'utilisation)
- utilisation de bois de qualités différentes suivant qu'ils servent de faces ou d'intérieurs (amélioration du prix de revient et des approvisionnements). ~
Le panneau à plate-bande conforme à la présente invention est fondamentalement caractérisé en ce que certaines couches forment ou sont destinées à former par usinage la platcbande du panneau et en ce que d'autres couches forment ou sont destinées à former par usinage la ou les parties saillantes du panneau, en ce que la couche extérieure d'une partie saillante et la couche extérieure correspondante de la plate-bande sont constituées par des placages. semblables et en ce que le panneau comporte des placages à fils croisés ou autres couches d'armature destinées à rigidifier le panneau.
In fact, the invention also provides the following advantages
- combinations of veneers in practically unlimited thicknesses
- possible presentation in the form of stable non-machined panels which will remain stable and rigid after machining
- more stable material than solid wood;
- dry material (humidity close to the humidity of use)
- use of wood of different qualities depending on whether they serve as faces or interiors (improvement of cost price and supplies). ~
The flowerbed panel according to the present invention is basically characterized in that certain layers form or are intended to form by machining the plate of the panel and in that other layers form or are intended to form by machining the projecting parts of the panel, in that the outer layer of a projecting part and the corresponding outer layer of the flower bed are formed by veneers. similar and in that the panel includes cross-wire plating or other reinforcing layers intended to stiffen the panel.

Dans des réalisations avantageuses, le panneau présente-en outre une ou plusieurs des particularités suivantes
- une partie saillante est constituée par ou comprend une couche épaisse, un placage à. fil croisé ou autre couche d'armature et un placage extérieur à fil parallèle, la couche épaisse ayant une couleur voisine de celle du placage extérieur,
- la couche épaisse est en bois massif, en aggloméré, en fibres et analogues ou est constituée de plusieurs placages collés à fils parallèles,
- la plate-bande est constituée de deux placages extérieurs à fils parallèles et d'une couche intermédiaire,
- la plate-bande est constituée de deux placages extérieurs à fils parallèles,. d'une couche intermédiaire et d'un placage à fil croisé ou autre couche d'armature entre la couche intermédiaire et chacun des placages extérieurs,
- l'épaisseur totale des placages à fils croisés est au plus égale à 25%, de préférence au plus égale à 10% de l'épaisseur totale du panneau,
- les couches d'armature comprennent des nappes de tissé ou de non tissé enduites de résine et durcies,
le panneau comporte une seule partie saillante qui est plus. épaisse, de préférence au moins deux fois plus épaisse, que la plate-bande,
- le panneau comporte deux parties saillantes d'épaisseurs différentes situées de part et d'autre de la plate-bande
- le panneau est symétrique par rapport à la plate-bande.
In advantageous embodiments, the panel also has one or more of the following features

On décrira ci-après deux réalisations de panneaux conformes à la présente invention, en référence aux figures du dessin joint qui sont deux coupes verticales des panneaux avant usinage.  Two embodiments of panels in accordance with the present invention will be described below, with reference to the figures in the accompanying drawing which are two vertical sections of the panels before machining.

Le panneau de la figure 1 comprend la succession des plis suivants qui sont collés sous pression i 1 : placage de 0,6 mm à fil parallèle
2 : placage de 1,1 mm à fil croisé
3, 4, 5, 6 : placages de 2 mm à fils parallèles
7 : placage de 2 mm à fil parallèle
8 : placage de 1,1 mm à fil croisé
9 : placage de 2 mm à fil parallèle
10 : placage de 1,1 mm à fil croisé
11 : placage de 0,6 mm à fil parallèle.
The panel of FIG. 1 comprises the succession of the following folds which are glued under pressure i 1: 0.6 mm plating with parallel wire
2: 1.1 mm cross wire plating
3, 4, 5, 6: 2 mm veneers with parallel wires
7: 2 mm plating with parallel wire
8: 1.1 mm cross wire plating
9: 2 mm plating with parallel wire
10: 1.1 mm cross-wire plating
11: 0.6 mm plating with parallel wire.

Le placage de parement 1 et le placage 7 sont de même essence et les placages 3 à 6 ont une couleur aussi voisine que possible de celle de ces placages. The facing veneer 1 and the veneer 7 are of the same essence and the veneers 3 to 6 have a color as close as possible to that of these veneers.

Après découpe selon les traits pointillés 15, le panneau présentera une plate-bande constituée par les parties visibles des plis 7 à 11 et un relief pyramidal constitué par les plis 1 à 6. Vu dans le sens de.la flèche 14, il présentera une façade 16, des chants 15 et des plates-bandes 12, 13 qui auront des aspects identiques en sorte que le panneau donnera l'impression du bois massif. After cutting along the dotted lines 15, the panel will have a border formed by the visible parts of the folds 7 to 11 and a pyramid relief formed by the folds 1 to 6. Seen in the direction of the arrow 14, it will have a facade 16, edges 15 and flowerbeds 12, 13 which will have identical aspects so that the panel will give the impression of solid wood.

La couche épaisse de la partie saillante, constituée ici des quatre plis 3 à 6, peut sans difficulté comporter un nombre supérieur de plis et, par exemple, huit plis, soit une épaisseur de 16 mm, donc beaucoup plus importante que celle de la portion plate-bande. The thick layer of the protruding part, consisting here of the four plies 3 to 6, can without difficulty comprise a greater number of plies and, for example, eight plies, that is to say a thickness of 16 mm, therefore much greater than that of the portion flower bed.

On notera que le panneau est raidi par seulement trois plis croisés 2, 8, 10 dont l'épaisseur totale (3,3 mm) est faible par rapport à l'épaisseur totale du panneau (16,5mm) alors que dans un contreplaquél'épaisseur des plis croisés représente généralement 40 à 602 de l'épaisseur du panneau. Note that the panel is stiffened by only three crossed folds 2, 8, 10 whose total thickness (3.3 mm) is small compared to the total thickness of the panel (16.5 mm) while in a plywood thickness of the folds generally represents 40 to 602 of the thickness of the panel.

Le panneau de la figure 2 est un panneau double face qui comprend la succession des plis suivants collés sous pression
17 : placage de 0,6 mm à fil parallèle
18 : placage de 1,1 mm à fil croisé
19, 20, 21, 22 : placages de 2 mm à. fils parallèles
23, 24, 25 : placages de 2 mm à fils parallèles
26, 27 : placages de.2'mm à fils parallèles
28 : placage de 1,1 sm à fil croisé
29 : placage de 0,6 mm à fil parallèle
Après découpage selon les traits pointillés 30, le panneau présentera une plate-bande constituée par les parties visibles des plis 23 à 25 et deux reliefs pyramidaux constitués respectivement par les plis 17 à 22 et 26 à 29.
The panel of Figure 2 is a double-sided panel which includes the succession of the following folds glued under pressure
17: 0.6 mm parallel wire plating
18: 1.1 mm cross-wire plating
19, 20, 21, 22: veneers from 2 mm to. parallel wires
23, 24, 25: 2 mm veneers with parallel wires
26, 27: 2'mm veneers with parallel wires
28: 1.1 sm cross-wire plating
29: 0.6 mm plating with parallel wire
After cutting along the dotted lines 30, the panel will have a border formed by the visible parts of the folds 23 to 25 and two pyramidal reliefs formed respectively by the folds 17 to 22 and 26 to 29.

Les placages 17 et 23 sont dans une même essence et la couleur des placages 19 à 22 est choisie aussi voisine que possible de celle de ces placages. The veneers 17 and 23 are of the same species and the color of the veneers 19 to 22 is chosen to be as close as possible to that of these veneers.

Les placages 29 et 25 sont dans une même essence et la couleur des placages 26 et 27 est choisie aussi proche que possible de celle des placages 29 et 25. The veneers 29 and 25 are of the same species and the color of the veneers 26 and 27 is chosen as close as possible to that of the veneers 29 and 25.

On notera que les deux reliefs pyramidaux ont des épaisseurs. différentes. It will be noted that the two pyramidal reliefs have thicknesses. different.

Ces exemples ne sont pas limitatifs de la portée de l'invention. These examples are not limitative of the scope of the invention.

Ainsi, dans une variante, le pli 24 est un placage à fil croisé. Thus, in a variant, the fold 24 is a cross-wire plating.

Dans d'autres variantes, la couche extérieure d'une partie saillante et la couche extérieure correspondante de la plate bande sont constitudes par des placages d'essences différentes mais susceptibles d'offrir le même aspect, ou des aspects peu différents, après un traitement de finition approprié, par exemple une teinture ou similaire.  In other variants, the outer layer of a protruding part and the corresponding outer layer of the flower bed are formed by veneers of different species but capable of offering the same appearance, or slightly different aspects, after treatment. suitable finish, for example a stain or the like.
