Abstract

The invention relates to a device for drawing parallel or inclined lines on a portable drawing board. It consists of a cursor 1 through which a tube 2 passes. On its rear face, two holes 3 leading to the tube 2 are internally provided with two steel balls 4, a spring 5 and an adjusting screw 6. A nylon screw 7 enables the cursor 1 to be locked to the tube 2. The top face of the cursor 1 possesses a centring stud 8 and a joining screw 9 for holding a rule 10 having a slot 11 and able to be inclined and locked at any chosen angle by means of the protractor 12 and able to rotate through 180 DEG relative to the drawing board. The device according to the invention is particularly intended for all types of portable drawing boards.

Description

DISPObIBIF DE GUIDAGE D'UNE RDGLE AU2Q-PERAILELE POUR
PLANCHE A DESSIN PORmADIV. GUIDING AVAILABILITY OF AN AU2Q-PERAILELE RDGLE FOR
PORmADIV DRAWING BOARD.

La présente invention concerne un dispositif pour entrainer une règle auto-parallèle sur une planche à dessin portative. The present invention relates to a device for driving a self-parallel rule on a portable drawing board.

Le dessin sur les planches de petites dimensions se fait ge-nera- lement à l'aide d'un té en bois ou en matières synthétiques r ce qui oblige l'utilisateur à avoir une main constanment prise pour maintenir toujours en contact la tête du té au bord de la planche ce qui n'assure pas souvent un guidage et un équérrage parfait. The drawing on the boards of small dimensions is generally done using a wooden or synthetic tee r which obliges the user to have a hand constantly taken to always keep in contact the head of the tee at the edge of the board which does not often ensure perfect guidance and squaring.

Ce dispositif selon l'invention permet de remédier à ces inconvénients. Il se compose d'un tube solaire par ses deux extrémités à un seul côté de la planche à dessin. This device according to the invention overcomes these drawbacks. It consists of a solar tube by its two ends to one side of the drawing board.

Ce tube possède un curseur qui coulisse librement. Celui-ci est relié à sa partie supérieure à une règle plate ce qui parmet à cette dernière d'avoir un déplacement toujours parallèle sur la surface de la planche à dessin
La liaison règle-curseur se fait par un pion de centrage et d'une vis de liaison permettant d'incliner la règle puis de la bloquer dans la position choisie et ,ainsi tracer des traits inclinés mais toujours parallèles entre eux.This tube has a slider that slides freely. This is connected at its upper part to a flat rule which allows the latter to have a displacement always parallel on the surface of the drawing board
The ruler-cursor connection is made by a centering pin and a connecting screw making it possible to tilt the ruler then to block it in the chosen position and, thus, draw inclined lines but always parallel to each other.

Une vis nylon, située sur la face arrière du curseur permet de le bloquer, empêchant éventuellement. toute mobilité de la règle. A nylon screw, located on the back side of the slider allows to block it, possibly preventing. any mobility of the rule.

Le curseur étant mobile autour du tabes la règle peut avoir une rotation de 1800, dégageant ainsi totalement la planche à dessin mais tout en restant solidaire de celle-ci ou bien être rapidement enlevée en défaisant la vis de liaison règle-curseur. The cursor being movable around the tabs the ruler can have a rotation of 1800, thus completely freeing the drawing board but while remaining integral with it or else be quickly removed by undoing the ruler-cursor connecting screw.

Selon une forme de réalisation préférencielle, le curseur peut être constitué en aluminium usiné ou moulé, soit en matières synthétiques rigides moulé par injection. According to a preferred embodiment, the cursor can be made of machined or molded aluminum, or of rigid synthetic materials injection molded.

Selon la variante, le curseur, sil est moulé, pourra être pourvu à l'intérieur de deux bagues ou coussinets rapportés. According to the variant, the cursor, if it is molded, may be provided inside two added rings or bearings.

La figure I représente en perspective le dispositif selon l'invention et les particularités du curseur. Figure I shows in perspective the device according to the invention and the features of the cursor.

La figure 2 représente én perspective une variante à ce dispcsitif. Figure 2 shows in perspective a variant to this dispcsitif.

Le dispositif représenté sur la figure I , se compose d'un curseur (I) coulissant le long d'un tube (2) et ayant des dimensions de l'ordre de 5 cm de long, 4,5 cm de large, 3 cm d'épais seur Sur la face arrière, sont percés trois trous débouchant sur le tube (2): deux trous (3) contenant chacun deux billes d'acier (b), un ressort (5) de rattrapage de jeu, une vis de réglage (6), le troisième possédant une vis nylon (7) servant au bloquage du curseur (I) immobilisant ainsi la règle (po).  The device shown in Figure I, consists of a cursor (I) sliding along a tube (2) and having dimensions of the order of 5 cm long, 4.5 cm wide, 3 cm thick On the rear side, three holes are drilled opening onto the tube (2): two holes (3) each containing two steel balls (b), a spring (5) for taking up play, a screw adjustment (6), the third having a nylon screw (7) used to lock the slider (I) thus immobilizing the rule (in).

La règle (IO) étant reliée sur la face du curseur (I) par un pion de centrage (8) et d'une vis de liaison (9) peut être inclinée précisément grace à une lumière (II) et rapporteur d'angle (I2
Dans la forme de réalisation selon la figure 2, le curseur (I) est muni à l'intérieur de deux bagues rapportées aux coussinets (I3) de type fltéflont ou similaire.The rule (IO) being connected on the face of the cursor (I) by a centering pin (8) and a connecting screw (9) can be tilted precisely thanks to a light (II) and protractor ( I2
In the embodiment according to FIG. 2, the cursor (I) is provided inside two rings attached to the bearings (I3) of fltéflont type or the like.

Ce dispositif selon l'invention est particulièrement destiné à tous les modèles de planches à dessin portatives.  This device according to the invention is particularly intended for all models of portable drawing boards.
