Abstract

The invention relates to a device offering all the facilities of a drawing apparatus employing articulated parallelograms, up to A2 format. It is more basic and robust in design. It may be placed either on a support adjustable for height, or in the manner of a console on a vertical wall. In the latter case, it can be folded away, in which position it has the appearance of a picture with a moulded frame. It consists of a laterally movable parallel rule 3 and a turntable 4 supported on a board 1. The rule is suspended from a counterweight 2. The device according to the invention is designed for teaching purposes in classes of vocational or other apprenticeship training, or for people having to work at home.

Description

La présente invention consiste en un dispositif destiné rendre tous les services d'un appareil à dessiner classique a' parallélogrammes ou à bras coulissant, muni d'une tête à dessiner et équipé de deux règles graduées disposées à angle droit. The present invention consists of a device intended to render all the services of a conventional drawing apparatus with parallelograms or with sliding arm, provided with a drawing head and equipped with two graduated rulers arranged at right angles.

Le dispositif selon l'invention est utilisé normalement
Pour les dessins techniques Jusqutau format A2 (594X420). Il permet une construction plus rustique, un encombrement plus réduit. Il contient moins de pièces fragiles et d'exécution précise.
The device according to the invention is used normally
For technical drawings Up to A2 format (594X420). It allows a more rustic construction, a smaller footprint. It contains fewer fragile parts and precise execution.

Le dispositif selon l'invention comporte deux versions. The device according to the invention has two versions.

Une première version d'après les figures 1 et 2. Dans cette version le dispositif est vissé sur une console (t) figure 2,coulissant dans ut support (.2) figures i et 2,per- mettant de régler la hauteur par rapport au sol grace à une crémaillère et un cliquet. A first version according to Figures 1 and 2. In this version the device is screwed onto a console (t) Figure 2, sliding in a support (.2) Figures i and 2, allowing to adjust the height relative on the ground thanks to a rack and a ratchet.

Une deuxième version dans laquelle le dispositif est fixé sur une paroi verticale. Le dipositif peut alors prendre deux positions
Une position dépliée, figures 3, 4 et 5.
A second version in which the device is fixed on a vertical wall. The device can then take two positions
An unfolded position, Figures 3, 4 and 5.

Une position repliée, figures 6, 7 et 8. Dans cette dernière position, il se présente tout à fait comme un tableau et a de ce fait un aspect décoratif. A folded position, Figures 6, 7 and 8. In this last position, it looks quite like a painting and therefore has a decorative appearance.

La première version comporte essentielement, figures et 2, une règle parallèle (3Y et un plateau (4), tournant sur un axe et supportant le dessin. The first version essentially comprises, figures and 2, a parallel ruler (3Y and a plate (4), rotating on an axis and supporting the drawing.

La règle parallèle possède, en plus du mouvement de translation habituel, un mouvement de translation latéral, selon l'axe de la règle. The parallel rule has, in addition to the usual translational movement, a lateral translational movement, along the axis of the rule.

De ce fait la règle est graduée puisque ce glissement latéral permet l'utilisation d'une graduation. Therefore the rule is graduated since this lateral sliding allows the use of a graduation.

La regle est suspendue par deux brins de cable (5) figure lbet (6) figures 1 et 2 à chacunes de ses extémité.Ces brins sur les poulies s'enroulent symétriquement/(7) et (8) figure 1,et (9) et (10) figures let 2. L'autre extrémité de chacun des brins (5) et (6 .st fixée à un même contre-poids t12) figure 2. The rule is suspended by two strands of cable (5) figure lbet (6) figures 1 and 2 at each of its ends. These strands on the pulleys are wound symmetrically / (7) and (8) figure 1, and (9 ) and (10) figures let 2. The other end of each of the strands (5) and (6 .st fixed to the same counterweight t12) figure 2.

il y a équilibre, dans toutes es positions de la règle (3), le long des glissières (13) et (14) figure 1, du panneau support (11) figures 1 et 2, entre l'action du contre-poids et le poids propre de la règle.  there is balance, in all positions of the rule (3), along the slides (13) and (14) in Figure 1, of the support panel (11) in Figures 1 and 2, between the action of the counterweight the dead weight of the rule.

Pour le déplacement vertical , la règle se comporte comme une règle parallèle classique. Pour le déplacement latéral, les brins de cables traversent deux orifices (15) et (16) figures 1 et 2, qui s1opposent à l'enroulement du cable d'un coté et à son déroulement de l'autre, sur les poulies (7) et (9).  For vertical displacement, the ruler behaves like a classic parallel ruler. For lateral movement, the strands of cables pass through two orifices (15) and (16) Figures 1 and 2, which oppose the winding of the cable on one side and its unwinding on the other, on the pulleys (7 ) and (9).

Le contre-poids (12) est plat et se déplace près d'une surface plane verticale. Il ne peut donc pas tourner sous 1 'effet de la torsion préexistante dans les brins de cables; ce qui provoquerait le croisement des brins et gènerait l'enroulement du cable sur les poulies. The counterweight (12) is flat and moves near a flat vertical surface. It cannot therefore rotate under the effect of the pre-existing torsion in the strands of cables; which would cause the strands to cross and cause the cable to wind up on the pulleys.

Le plateau tournant t4) est muni d'un pivot (17) figure 2, et pivote de 180 sur le panneau support (11). Ce panneau a une inclinaison fixe de 45 à 50 par rapport à la verticale
Une butée parallèlépipédique (18) figure 1, déplaçable manuellement à droite ou à gauche,peut Imiter la rotation de (4) à 900 avec précision, vers la droite ou vers la gauche.
The turntable t4) is provided with a pivot (17) in Figure 2, and pivots 180 on the support panel (11). This panel has a fixed inclination of 45 to 50 relative to the vertical
A parallelepipedal stop (18) figure 1, manually movable to the right or to the left, can precisely imitate the rotation from (4) to 900, to the right or to the left.

La butée (18) étant écartée, le reliage angulaire de (4) peut se faire sur tout angle grace à un index (19) et à une graduation (20) figure 1. te freinage sur un angle donné se fait par le poids propre des pieces en contact. The stop (18) being spread, the angular connection of (4) can be done on any angle thanks to an index (19) and a graduation (20) figure 1. braking on a given angle is done by the dead weight parts in contact.

La rotation de la table (4) se commande d'un doigt placé dans l'orifice (21) figure 1, de l'index 19. Le mou vement est particulièrement rapide et aisé dans le cas de la rotation à 900, grace à la butée (18)
La combinaison des translations de (3) et de la rotation de (4) permet le tracé de tout trait rectiligne, de position et de longueur déterminées.
The rotation of the table (4) is controlled by a finger placed in the orifice (21) in Figure 1, with the index 19. The movement is particularly rapid and easy in the case of rotation at 900, thanks to the stop (18)
The combination of the translations of (3) and the rotation of (4) allows the drawing of any rectilinear line, of determined position and length.

La deuxième version comporte Ies modifications swi- vantes, d'après les figures 3 à 8. The second version includes the following modifications, as shown in Figures 3 to 8.

Les poulies (7) à (10) sont fixées sur une traverse (1) figures 3, 4 et 7, scellée par deux tampons sur une paroi verticale, mur ou cloison. Le panneau support ) figures 3à 8, est articulé sur Ia traverse (1). Il est entouré d'un cadre mouluré (2) articulé sur ce même panneau (11). Dans la position dépliée, le panneau est maintenu en position incliné par le cadre (2) dbnt la rotation est limitée par un compas (22) figure 4. L'ensemble forme console. The pulleys (7) to (10) are fixed on a crosspiece (1) Figures 3, 4 and 7, sealed by two buffers on a vertical wall, wall or partition. The support panel) Figures 3 to 8, is articulated on Ia cross (1). It is surrounded by a molded frame (2) articulated on this same panel (11). In the unfolded position, the panel is held in an inclined position by the frame (2) dbnt the rotation is limited by a compass (22) in figure 4. The assembly forms a console.

An position repliée, la règle t3) est logée, figure 8, entre les charnières (23) et Bes glissières (13) et (44), figures 3 > 4 et 8, tandisque le panneau (11) est maintenu en position par la irmeture magnétique (24) figure 8. Le contre-poids (12) figures 4 et 7 se loge derrière la traverse (1). Deux pinces cable (25) figure 5 évitent la descente du contre-poids sous le cadre (?), car pendant l'opération de repliage, les cables prennent du mou. In the folded position, the rule t3) is housed, Figure 8, between the hinges (23) and Bes slides (13) and (44), Figures 3> 4 and 8, while the panel (11) is held in position by the magnetic closure (24) Figure 8. The counterweight (12) Figures 4 and 7 is housed behind the crosspiece (1). Two cable clamps (25) in Figure 5 prevent the counterweight from lowering under the frame (?), Because during the folding operation, the cables take up slack.

Le dispositif selon l'invention est particulièrement destiné, pour la première version, à l'enseignement du dessin industriel dans les classes préparant à ui C.A.P. ou à un
B.E.P., ou les classes de seconde techniques ou dans les bureaux d'études utilisant les formats 9e dépassant pas le A2.
The device according to the invention is particularly intended, for the first version, for teaching industrial design in the classes preparing for a CAP or a
BEP, or the second technical classes or in design offices using 9th formats not exceeding A2.

Pour Ia deuxième version, le dispositif à cause de son aspect décoratif, est destin particulièrement aux personnes ayant à travailler à leur domicile, étudiant ou professeur par exemple. La deuxième version permet de plus le rangement et la reprise du travail de dessin, après un temps quelconque très rapidement.  For the second version, the device because of its decorative aspect, is intended particularly for people having to work at their home, student or professor for example. The second version allows more storage and resumption of the drawing work, after any time very quickly.
