Abstract

A series of wooden bars (1,2) form the side members of a rectangular frame, with reinforcing wedges associated with their joints at the corners of the rectangle. The corner joints are formed by interengaging mortises and tenons on respective ends of each wooden bar. The wooden bars include a lip (4) on the front surface of their outer edge, with a semi-circular cross-section. The internal corners (5) of the lip at each corner location of the frame are rounded in configuration.

Description

La présente invention concerne un châssis expansible destiné à supporter des toiles de peintre, du type de ceux formés au moyen de lattes de bois assemblées, convenablement renforcé et expansible au moyen de cales, doté respectivement de rebords et de tenons qui permettent d'assembler des lattes les unes aux autres, et doté de systèmes de clavetage disposés contre les lattes et les tenons, qui permettent d'introduire les cales triangulaires pour déployer le châssis par percussion. The present invention relates to an expandable frame intended to support painter's canvases, of the type formed by means of assembled wooden slats, suitably reinforced and expandable by means of shims, provided respectively with flanges and tenons which make it possible to assemble slats to each other, and fitted with keying systems arranged against the slats and tenons, which allow the triangular wedges to be introduced to deploy the chassis by percussion.

Le présent modèle d'utilité dont les parties essentielles sont décrites dans ce mémoire, se réfère à un châssis déployable pour supporter des toiles de peintre, dont le dessin d'origine permet de réunir en un seul modèle les avantages jusqu'à maintenant incompatibles des modèles de face en longueur et à onglets , dénommés populairement en Espagne comme espagnol et français , en même temps qu'il élimine leurs défauts. The present utility model, the essential parts of which are described in this memo, refers to a deployable frame for supporting painter's canvases, the original design of which makes it possible to combine in a single model the previously incompatible advantages of long face and tab models, popularly known in Spain as Spanish and French, while eliminating their shortcomings.

Le châssis est conçu et dessiné, pour sa construction, au moyen de lattes de bois assemblées pour adopter une forme quelconque rectangulaire ou carrée, de taille quelconque, convenablement renforcée. The frame is designed and drawn, for its construction, by means of wooden slats assembled to adopt any rectangular or square shape, of any size, suitably reinforced.

Laissant de côté les éléments de renforcement, traverses et croisillons qui sont nécessaires dans un châssis quelconque à partir de dimensions déterminées, la version de base se compose de quatre lattes disposées à angle droit, chacune avec la suivante, et assemblées au moyen d'un ensemble de fourche avec un tenon dépassant muni d'une petite crosse et de rebords, et avec une double queue d'aronde et la fin sur une queue d'aronde semi-circulaire. Leaving aside the reinforcing elements, crosspieces and crosspieces which are necessary in any chassis from predetermined dimensions, the basic version consists of four slats arranged at right angles, each with the next, and assembled by means of a set of forks with a protruding lug fitted with a small stock and edges, and with a double dovetail and the end on a semi-circular dovetail.

Fondamentalement, le modèle qui nous occupe se caractérise en ce que les lattes de forme de base rectangulaire et qui logent les éléments caractéristiques de l'ensemble cité à chaque extrémité, c'est-à-dire dans l'une les rebords et dans l'autre le tenon permettant d'assembler les lattes les unes dans les autres, se caractérisent essentiellement en ce que sur leur face antérieure et le long de leurs bords antéroextérieurs ces lattes disposent d'une saillie en forme de demicanne convexe qui empêche que la toile une fois tendue sur le châssis puisse toucher la face antérieure de celui-ci, les bords extérieurs et antéro-intérieurs étant arrondis. Basically, the model which occupies us is characterized in that the slats of rectangular base shape and which house the characteristic elements of the set cited at each end, that is to say in one the edges and in the '' the other tenon allowing to assemble the slats the ones in the others, are characterized essentially in that on their front face and along their antero-external edges these slats have a projection in the shape of convex demicanne which prevents that the fabric once stretched on the chassis can touch the front side thereof, the outer and antero-inner edges being rounded.

La saillie mentionnée, en forme de demi-canne convexe, augmente la surface de contact avec la toile et facilite la répartition homogène des tensions produites par les éléments de fixation clous ou agrafes qui l'assujettissent, en même temps qu'ils facilitent le clouage de la toile aussi bien sur le bord que par derrière. En utilisant les bords extérieurs et antéro-intérieurs arrondis, on évite que le bord puisse marquer la toile quand on applique la peinture avec une force spéciale. The protrusion mentioned, in the shape of a convex half-cane, increases the contact surface with the fabric and facilitates the homogeneous distribution of the tensions produced by the fastening elements nails or staples which subject it, at the same time that they facilitate nailing canvas both on the edge and behind. By using the rounded outer and anterior-inner edges, we avoid that the edge can mark the canvas when we apply the paint with a special force.

La conception originale de l'ensemble réunit une série d'avantages. Le fait qu'il s'agit d'un ensemble du type fourche assure une meilleure résistance dans les coins du châssis qui sont précisément parmi ses points les plus fragiles. La crosse assure que les lattes restent à angle droit et empêche que le châssis se désencadre sous l'effet de coups. La queue d'aronde sur la longueur de tout le périmètre des bords empêche que ceux-ci s'ouvrent vers l'extérieur avec le temps, et contribue à donner de la solidité à l'ensemble.Sa longueur est plus courte que la largeur du tenon dépassant, grâce à quoi on évite que des arêtes et des coins irréguliers puissent se former sur le bord du châssis quand on met en tension au moyen de cales, ou au cours du temps, et cela permet de répartir le long du bord antéro-extérieur du châssis la saillie semi-circulaire qui écarte la toile, en empêchant ainsi le contact du châssis avec elle. The original design of the set brings together a series of advantages. The fact that it is an assembly of the fork type ensures better resistance in the corners of the chassis which are precisely among its most fragile points. The stock ensures that the slats remain at a right angle and prevents the chassis from falling out under the effect of knocks. The dovetail along the entire perimeter of the edges prevents them from opening outwards over time, and contributes to giving solidity to the whole. Its length is shorter than the width. protruding tenon, which prevents irregular edges and corners from forming on the edge of the frame when tensioning by means of shims, or over time, and this allows distribution along the antero edge -exterior of the chassis the semi-circular projection which spreads the canvas, thus preventing contact of the chassis with it.

Pour une meilleure compréhension de ce qui précède, et sans que cela corresponde à une limitation quelconque de la généralité des applications possibles du modèle qui nous occupe, nous allons expliquer un mode concret de réalisation pratique à l'aide des figures jointes dans lesquelles
- la figure 1 représente une vue schématique de l'ensemble du cadre avec ses lattes et cales
- la figure 2 représente une vue en coupe des lattes qui forment le cadre ; et
- la figure 3 représente une vue de côté de ces lattes.
For a better understanding of the above, and without this corresponding to any limitation of the generality of the possible applications of the model in question, we will explain a concrete practical embodiment using the attached figures in which
- Figure 1 shows a schematic view of the entire frame with its slats and shims
- Figure 2 shows a sectional view of the slats which form the frame; and
- Figure 3 shows a side view of these slats.

Comme on peut l'observer dans ces figures, le cadre est fondamentalement composé de lattes longues 1 et de lattes courtes 2 assemblées au moyen des cales 3. Les lattes longues ou courtes 1 ou 2 présentent sur leur face antérieure et le long de leurs bords antéro-extérieurs une saillie 4 en forme de demi-canne allant jusqu'à l'extérieur, selon la représentation de la figure 2. D'autre part, ses coins antéro-intérieurs 5 sont arrondis selon l'illustration de la figure 3. As can be seen in these figures, the frame is basically composed of long slats 1 and short slats 2 assembled by means of shims 3. Long or short slats 1 or 2 have on their anterior face and along their edges antero-exterior a projection 4 in the form of a half-rod going up to the exterior, as shown in FIG. 2. On the other hand, its anterior-interior corners 5 are rounded according to the illustration in FIG. 3.

On n'altérera pas la partie essentielle du présent modèle d'utilité par toutes les modifications possibles de caractère secondaire telles que les formes et dimensions générales, les détails accessoires et construction ou de finissage, ni en général tout ce qui ne présuppose pas une variation profonde et importante de l'objet principal de l'invention tel que défini dans la revendication qui suit.  The essential part of this utility model will not be altered by all the possible modifications of a secondary character such as general shapes and dimensions, accessory details and construction or finishing, nor in general all that does not presuppose a variation. deep and important the main object of the invention as defined in the claim which follows.
