Abstract

The angle gauge has long fixed and moving arms (2)and a graduated circle with cut out through which protrudes a pointed guide finger (3) and clamp screw (4).

Description

La présente invention, concerne un dispositif précis de relevé et de report d'angles préalablement à leur exécution, tant en atelier que sur les chantiers. Il permet de plus de régler les pentes jusqu'à 5 Le relevé ainsi que le report d'angles est traditionnellement effectué à l'aide d'une fausse équerre ou d'un rapporteur d'angles. The present invention relates to a precise device for reading and transferring angles prior to their execution, both in the workshop and on construction sites. It also makes it possible to adjust the slopes up to 5 The reading as well as the transfer of angles is traditionally carried out using a false square or a protractor.

La fausse équerre d'une part, ne permet pas de connaître la valeur de l'angle, tandis que la petite taille du rapporteur d'angles restreint les possibilités de son utilisation. The false square on the one hand, does not allow to know the value of the angle, while the small size of the protractor restricts the possibilities of its use.

Ces procédés présentent un manque évident de précision et de fiabilité. Ce problème se trouve amplifié que les chantiers où les dimensions sont à une échelle plus importante qu'en bureau d'études ou en atelier et où des outils précis et de plus grande envergure sont nécessaires. These methods have an obvious lack of precision and reliability. This problem is amplified only on sites where the dimensions are on a larger scale than in a design office or workshop and where precise and larger tools are necessary.

Le dispositif selon l'invention permet de remédier à ces inconvénients ; Il comporte, selon une première caractéristique, une pièce principale pourvue à une extrémité d'un demi-cercle évidé et gradué de 0 à 180 . Les graduations sont en fait des encoches, de façon à permettre un positionnement plus précis au degré souhaité. L'extrémité demie sphérique possède en son centre un axe, autour duquel pivote un bras mobile de même longueur, permettant le réglage de l'angle. De plus, la partie inférieure, située à l'extrême droite de la pièce principale est coupée de biais, afin de permettre le réglage des pentes de 0 à 5 . The device according to the invention overcomes these drawbacks; According to a first characteristic, it comprises a main part provided at one end with a hollowed-out semi-circle graduated from 0 to 180. The graduations are in fact notches, so as to allow more precise positioning at the desired degree. The half spherical end has an axis at its center, around which pivots a movable arm of the same length, allowing the angle to be adjusted. In addition, the lower part, located at the extreme right of the main room is cut at an angle, to allow the adjustment of slopes from 0 to 5.

Un doigt guide pointu, solidaire du bras mobile permet le repérage aisé de l'angle. La partie inférieure du doigt guide est biseautée de façon à s'emboîter exactement dans les encoches pratiquées dans la partie demie sphérique de la pièce principale, dans le but d'obtenir une meilleure précision et un meilleur blocage. A pointed guide finger secured to the movable arm allows easy identification of the angle. The lower part of the guide finger is bevelled so as to fit exactly into the notches made in the semi-spherical part of the main part, in order to obtain better precision and better locking.

Une mollette montée sur le doigt guide permet le blocage du dispositif. Le dessin annexé, illustre l'invention La figure 1 représente l'invention vue de face. A knob mounted on the guide finger allows the device to be blocked. The accompanying drawing illustrates the invention. FIG. 1 represents the invention seen from the front.

En référence au dessin, l'invention possède une pièce principale (1) pourvue à une extrémité d'un demi-cercle évidé et gradué de 0 à l80 à l'aide d'encoches, possédant en son centre un axe (5) autour duquel le bras mobile (2) peut effectuer une rotation de 0 à l80 et possédant une découpe (A) permettant le réglage des pentes. With reference to the drawing, the invention has a main part (1) provided at one end with a hollowed-out semicircle graduated from 0 to 180 by means of notches, having an axis (5) around its center. from which the movable arm (2) can rotate from 0 to 180 and having a cutout (A) allowing the adjustment of the slopes.

Le doigt guide (3) pointu dont la partie inférieure est biseautée, solidaire du bras mobile (2) comporte une mollette de serrage (4) permettant le blocage du dispositif.
