Abstract
Description
L'invention est du domaine des matériaux, et plus particulièrement de la fabrication de panneaux en bois<B>à</B> partir de chutes de lattes, de plancher ou de volets notamment, et elle a pour objet un panneau obtenu<B>à</B> partir d'une telle fabrication. The invention is in the field of materials, and more particularly the manufacture of wooden panels <B> to </ B> from falls slats, floor or shutters in particular, and it relates to a panel obtained <B > to </ B> from such manufacture.
On connaît une technique consistant<B>à</B> récupérer des chutes de lattes de bois de même épaisseur et de même largeur, mais de longueur quelconque, pour les assembler entre elles en vue de former un panneau, dit "demi- produit", destiné<B>à</B> être utilisé en menuiserie pour constituer des plans de travail ou des tablettes d'étagère. Les lattes sont assemblées entre elles par emboîtement<B>.</B> et collage, par l'intermédiaire notamment d'un rainurage longitudinal dont elles sont<B>déjà</B> pourvues pour leur assemblage latéral, et par l'intermédiaire de profils d'emboîtement ménagés en bout de latte pour leur aboutement par exemple. It is known a technique consisting in recovering falls of wood slats of the same thickness and the same width, but of any length, to assemble them to form a panel, said "semi-product" ", intended <B> to </ B> be used in carpentry to constitute worktops or shelf shelves. The slats are assembled together by interlocking <B>. </ B> and bonding, in particular by means of a longitudinal grooving of which they are <B> already </ B> provided for their lateral assembly, and by the intermediate interlocking profiles formed at the end of batten for their abutment for example.
L'avantage évident de cette technique réside dans l'obtention<B>à</B> faible coût d'un panneau en bois<B>à</B> partir de matériaux de récupération. Toutefois, le panneau ainsi obtenu présente une fragilité au regard de sa résistance au fléchissement, dans le sens longitudinal plus particulièrement en raison de l'aboutement des chutes. The obvious advantage of this technique is the low-cost obtaining of a wooden panel from recycled materials. However, the panel thus obtained has a fragility with regard to its resistance to sagging, in the longitudinal direction more particularly because of the abutment falls.
Le but de la présente invention est de proposer un panneau en bois formé<B>à</B> partir de lattes de bois récupérées et assemblées entre elles, pour son obtention <B>à</B> moindre coût, qui présente néanmoins une résistance satisfaisante au fléchissement dans ses deux dimensions. The object of the present invention is to provide a wooden panel formed from recovered wooden slats and assembled together, for obtaining it at lower cost, which nonetheless presents satisfactory resistance to sagging in both dimensions.
La démarche inventive de la présente invention a consisté<B>à</B> proposer un panneau de bois du genre dit "demi-produit" formé<B>à</B> partir d'une pluralité de lattes de bois de récupération assemblées entre elles par emboîtement et collage, qui présente la caractéristique d'être composé de deux longerons massifs, c'est<B>à</B> dire chacun naturellement monobloc, qui sont entretoisés par des traverses, adjacentes entre elles pour former un panneau plein, les dites traverses occupant l'espace délimité entre les longerons. Grâce<B>à</B> ces dispositions, le panneau de l'invention est compétitif par rapport<B>à</B> un panneau fabriqué<B>à</B> partir de bois brut, c'est<B>à</B> dire de bois qui ne provient pas de matériaux de récupération, et présente néanmoins une résistance<B>à</B> la flexion satisfaisante. The inventive step of the present invention has been to provide a so-called "semi-finished" wood panel formed from a plurality of recovery wood slats. assembled together by interlocking and gluing, which has the characteristic of being composed of two massive spars, it is <B> to </ B> say each one naturally monobloc, which are bridged by sleepers, adjacent to each other to form a solid panel, the said sleepers occupying the space delimited between the longitudinal members. Thanks to these provisions, the panel of the invention is competitive with respect to a panel manufactured from raw wood, it is <B> to </ B> a panel manufactured <B> to </ B> from raw wood, it is < B> to </ B> of wood that does not come from recovery materials, and nevertheless has a resistance <B> to </ B> satisfactory bending.
De plus, quoique plus coûteux que les panneaux de l'art antérieur fabriqués<B>à</B> partir de lattes de récupération, le panneau de l'invention présente les avantages par rapport<B>à</B> ceux-ci d'être rabotable, la matière étant toujours enlevée du panneau, tant longitudinalement que transversalement, dans le sens de la fibre du bois, et --d'optimiser la récupération des matériaux dans la mesure<B>où</B> même les lattes de courte longueur sont récupérables pour former les traverses. In addition, although more expensive than the prior art panels manufactured from recovery slats, the panel of the invention has the advantages over those of it is planing, the material is always removed from the panel, both longitudinally and transversely, in the direction of the wood fiber, and --optimize the recovery of materials in the measurement <B> where </ B> even the slats of short length are recoverable to form the sleepers.
On notera aussi qu'une application privilégiée d'un panneau de l'invention étant une tablette d'étagère, la tranche de cette dernière présente avantageusement un aspect continu et massif valorisant pour un demi-produit. Note also that a preferred application of a panel of the invention being a shelf shelf, the edge of the latter advantageously has a solid and solid aspect for a semi-product.
Enfin, la résistance globale<B>à</B> la flexion du panneau dans le sens longitudinal ne se trouve pas modifiée, que les longerons et les traverses soient de même épaisseur ou alternativement que les traverses soient d'une épaisseur plus faible que celle des longerons, ce qui dans ce dernier cas permet de réduire la masse globale de bois nécessaire<B>à</B> la fabrication d'un panneau, et donc de réduire son coût de revient afin d'accroître sa compétitivité au regard des panneaux du même genre de l'art antérieur. Finally, the overall resistance <B> to </ B> the bending of the panel in the longitudinal direction is not modified, that the longitudinal members and the cross members are of the same thickness or alternatively that the sleepers are of a lower thickness than that of the side members, which in the latter case reduces the overall mass of wood needed for the manufacture of a panel, and therefore reduces its cost price in order to increase its competitiveness with regard to panels of the same kind of the prior art.
La présente invention sera mieux comprise et des détails en relevant apparaîtront,<B>à</B> la description qui va en être faite d'une forme préférée de réalisation, en relation avec les figures de la planche annexée, dans lesquelles: la fig.1 illustre un panneau de l'art antérieur formé<B>à</B> partir de lattes en bois de récupération, la fig.2 illustre un panneau en bois selon une forme préférée de réalisation. la fig.3 est une vue de bout d'un jeu de panneaux superposés de l'invention, tels que représentés sur la fig.2, illustrant un autre aspect de l'invention. The present invention will be better understood and details will arise, <B> to </ B> the description that will be made of a preferred embodiment, in connection with the figures of the attached plate, in which: the Fig. 1 illustrates a prior art panel formed from wooden laths, Fig. 2 illustrates a wooden panel according to a preferred embodiment.
