Abstract

The surface of the board (1) is inclined at an angle of between 10 and 15 deg. to the table top (2) etc. on which it is supported, with a wedge or support portion (3) attached to its lower face. The support is removable and has a V-shaped cross-section. The support is defined by a rectangular sheet of rigid material, e.g. strong cardboard, folded to define a channel (22) with edge flanges (6,7). The edge flanges engage in slots defined by a series of projections (8,10) on the rear face of the board to allow attachment in one of a number of different positions. ADVANTAGE - Simple low-cost support structure, allowing adjustment to different working angles.

Description

L'invention concerne les planche à dessin que l'on utilise en les posant sur une table et en se servant d'un té tenu à la main. The invention relates to drawing boards which are used by placing them on a table and using a hand-held tee.

Actuellement ces planches sont posées à plat sur une table, ce qui présente le grave inconvénient de fatiguer la vue, le regard du dessinateur étant trop oblique par rapport à son dessin; le traçage des traits contre le té devant être précis, oblige le dessinateur à se pencher en avant pour mieux voir. Currently these boards are placed flat on a table, which has the serious drawback of tiring the view, the eyes of the designer being too oblique to his drawing; the tracing of the lines against the tee having to be precise, obliges the designer to lean forward to see better.

Ces ennuis fatiguent le dessinateur et dissipe son attention. These troubles tire the designer and dissipate his attention.

Au préalable les feuilles de papier ont du être fixées sans repères, ce qui rend leur positionnement exact délicat. Beforehand, the sheets of paper had to be fixed without marks, which makes their exact positioning difficult.

La présente invention remédie à ces inconvénients
La planche n'est pas posée à plat, mais forme avec la table un angle de 10 à 15 degrés environ, ce qui permet de reposer la vue et rend le travail plus agréable.The present invention remedies these drawbacks
The board is not laid flat, but forms an angle of about 10 to 15 degrees with the table, which allows you to rest your view and makes work more pleasant.

Cette inclinaison qui permet de mieux voir Le tracé horizontal contre le té,est obtenue à l'aide d'une cale ou d'un chevalet formant béquille, fixée de façon amovible sous la partie haute de la planche par des plots à gorge, des taquets ou autres petites pièces appropriées. This inclination which allows a better view The horizontal line against the tee, is obtained using a wedge or an easel forming a crutch, fixed in a removable manner under the upper part of the board by throat studs, cleats or other suitable small parts.

Ce chevalet, par exemple, pourra être ainsi fixé soit paral lélement à l'un des grands côtés, soit à l'un des petits côtés, afin de permettre d'incliner la planche dans l'un ou L'autre sens
Cete planche concerne surtout les dessinateurs qui, n'étant pas des professionnels, ut Lisent généraLement le papier de format commercial normalisé ou deux de ces feuilles placèes côte à côte par L'un de leurs grands côtés.This easel, for example, can thus be fixed either parallel to one of the long sides, or to one of the short sides, in order to allow the board to be tilted in one or the other direction.
This sheet mainly concerns designers who, not being professionals, generally read standard commercial size paper or two of these sheets placed side by side by one of their long sides.

Pour favoriser la mise en place précise de ces feuilles, La planche comporte des cadres imprimés à leurs dimensions. To favor the precise placement of these sheets, the board has frames printed to their dimensions.

Les dessins 1/1 et 1/2 représentent une réalisation préférentielle de l'invention. La fig. 1 du dessin 1/1, représente ta planche (1) posée sur la table (2), et qui est maintenue oblique par le chevalet (3) . Elle montre également les cadres (4) et (5) facilitant le positionnement de ces formats standards. The drawings 1/1 and 1/2 represent a preferred embodiment of the invention. Fig. 1 of the drawing 1/1, represents your board (1) placed on the table (2), and which is held oblique by the easel (3). It also shows the frames (4) and (5) facilitating the positioning of these standard formats.

La figure 1 du dessin 1/2 représente la même planche retournée, vue de dessous; elle montre le chevalet (3) maintenu en sa forme en V, par ses bords (6) et (7), coincés p-r sous les plots (8) (9) (10) et (11). Figure 1 of drawing 1/2 shows the same inverted board, seen from below; it shows the easel (3) maintained in its V shape, by its edges (6) and (7), wedged p-r under the studs (8) (9) (10) and (11).

Le chevalet est avantageusement constitué par un rectangle de carton fort, recouvert ou non, comportant des rainures, ou des refoulures (21) (22) (23) à l'emplacement des pliures permettant La forme en V. The easel is advantageously constituted by a rectangle of strong cardboard, covered or not, comprising grooves, or grooves (21) (22) (23) at the location of the folds allowing the V shape.

La Fig. 2 montre, en coupe AA', la planche (1) posée sur la table (2) avec son chevalet amovible en V (3), formant une béquille solide, avec un certain ressort maintenant ses bords (6) et (7) coincés sous les plots (8) et (10). Fig. 2 shows, in section AA ′, the board (1) placed on the table (2) with its removable V-shaped easel (3), forming a solid stand, with a certain spring keeping its edges (6) and (7) wedged under the studs (8) and (10).

La FIG. 3 montre Le té (20) avec à son extrémité, la butée (24) l'empêchant de glisser en bas de La planche (1) lorsqu'il est lâché et se met alors Légèrement de biais. FIG. 3 shows the tee (20) with at its end, the stop (24) preventing it from sliding down the board (1) when it is released and is then placed slightly at an angle.

Enfin des plots, ou des taquets par ex., placés judicieusement pour ne pas géner la mise en place du chevalet monté, permettront, pour le rangement, de maintenir celui-ci à plat contre le verso de la planche (1),ainsi que les autres accessoirs, té, règle, équerres, etc... Finally, studs, or cleats for example, placed judiciously so as not to interfere with the installation of the mounted easel, will allow, for storage, to keep it flat against the back of the board (1), as well as other accessories, tee, ruler, brackets, etc ...

La présente invention concerne aussi bien les écoliers que Les particuliers ou les professionnels mêmes. The present invention relates to schoolchildren as well as individuals or professionals themselves.

Elle sera susceptible, son prix de revient étant faible, d'être vendue en grandes surfaces notamment, ce qui nécessitera des fabications importantes. It will be likely, its cost price being low, to be sold in supermarkets in particular, which will require significant fabrication.
