Abstract

The invention relates to a device which allows on the one hand any angle in a vertical plane to be measured, and on the other hand the bulk of the instrument to be reduced to a minimum. The device includes two graduated tubes 1 and 2 of circular shape and cross-section, filled with a liquid 6 and 7 and each containing a gas bubble 8 and 9. The support has a flat carrying face 11 and a reading flap 13. During use, when the instrument makes an angle with the horizontal plane, the bubble becomes offset by the same angle with respect to the graduation 0 DEG and gives, by reading, the value of this angle. The device also allows the same angle to be plotted indefinitely. The device according to the invention is in particular intended for masonry work.

Description

La Présente invention concerne un dispositif pour la mesure des ongles par rapport à l'horizontale et leur report. The present invention relates to a device for measuring the nails relative to the horizontal and their transfer.

les Appareils traditionnels ne donnent que lthorizontalité t la verticalité; Seuls, des anDareils de haute précision, mesurent tous les angles, mais sont troo précis et trop fragiles pour hêtre utilisés en maçonnerie. D'autres appareils à aiguille ont, pour des raisons d'emcombrement, des graduations beaucoup trop petites, ce qui les rend illisibles et imprécis. traditional devices only give horizontality and verticality; Only high precision devices measure all angles, but are too precise and too fragile to be used in masonry. Other needle devices have, for reasons of congestion, much too small graduations, which makes them illegible and imprecise.

Le dispositif, selon l'invention, permet de remédier à ces inconvénients. The device according to the invention overcomes these drawbacks.

Selon une réalisation préférentielle, il décompose, par une translation rectangulaire, le quart de cercle (de 0 à 900) en deux narties, permettant ainsi, une échelle de graduation tris lisible, nour un encombrement deux fois moindre. According to a preferred embodiment, it decomposes, by a rectangular translation, the quarter circle (from 0 to 900) into two narties, thus allowing, a tris graduation scale readable, nour a congestion twice less.

Le dispositif, représenté par la figure I, comporte deux tubes (l) et (2) de forme et de section circulaires, de même rayon et gradués des deux côtés en degrés, l'un de 0 à 700 (4), l'autre de 600 à 900 (5), remplis d'un liquide trbs fluide (6) et (78 et renfermant chacun une bulle de gaz (8) et (9) dont la dimension, dans la réalisation présente, équivaut à I00 de graduation. The device, represented by FIG. I, comprises two tubes (l) and (2) of circular shape and section, of the same radius and graduated on both sides in degrees, one from 0 to 700 (4), l ' other from 600 to 900 (5), filled with a very fluid liquid (6) and (78 and each containing a gas bubble (8) and (9) whose dimension, in the present embodiment, is equivalent to I00 of graduation .

Le support (42) de l'ensemble (4) et (2), en matériau rigide et résistant, comporte une face portante plane (|1) et une trappe de lecture (83) de l'horizontale, sur la face supérieure. The support (42) of the assembly (4) and (2), made of rigid and resistant material, has a flat bearing face (| 1) and a reading hatch (83) from the horizontal, on the upper face.

Le dispositif est placé, dans le support, de telle façon aue le rayon de la courbure du tube (4), passant par la graduation 50, est perpendiculaire à la face portante (11)
Ls orotection (40) des deux tubes en verre (4) et (2), de forme comcentrioue à ces tubes, de section carrée ou rectangulaire,est réalisée en matière plastique résistante et transparente, par procédé de moulage ou autres.The device is placed in the support so that the radius of the curvature of the tube (4), passing through the scale 50, is perpendicular to the bearing face (11)
The orotection (40) of the two glass tubes (4) and (2), of form concentrious to these tubes, of square or rectangular section, is made of resistant and transparent plastic, by molding process or others.

La mise en place du systbme,(40) dans le support (42), selon une réalisation préférentielle, se fera par la face inférieure (41), nar glissement, dans une cavité de même forme (44), munie de guides (15).Les deux parties du systhme sueront maintenues immobiles par un procédé de blocage ne dépassant pas du talon de l'appareil (11). The establishment of the system (40) in the support (42), according to a preferred embodiment, will be done by the lower face (41), nar sliding, in a cavity of the same shape (44), provided with guides (15 The two parts of the system will be kept immobile by a blocking process not exceeding the heel of the device (11).

La figure I représente le dispositif selon l'invention. Figure I shows the device according to the invention.

La figure 2 représente en coupe l'ensemble tube et protection. Figure 2 shows in section the tube and protection assembly.

La figure 5 représente,en coupe,une variante de ce dispositif. Figure 5 shows, in section, a variant of this device.

La figure 3 représente la face plane portante de l'instrument. FIG. 3 represents the plane bearing face of the instrument.

La lecture de l'angle se fait sur le bord gauche de la bulle (8) et (9) quelle oue soit sa position.The angle is read on the left edge of the bubble (8) and (9) whatever its position.

Lorsque l'horizontalité de l'instrument est atteinte, la bulle (8) se trouve entre les graduations 0 et I00.When the horizontality of the instrument is reached, the bubble (8) is between the graduations 0 and I00.

Lorsque la bulle (8) du tube (4) arrive sur la position 600, la bulle (9) du tube (2), se trouvant sur le même axe que la premibre (8), (rayon passant par les deux graduations 650), prend le relais à la graduation 600 et permet la mesure jusqu'à 900, donnant ainsi la verticalité.When the bubble (8) of the tube (4) arrives at position 600, the bubble (9) of the tube (2), being on the same axis as the first (8), (radius passing through the two graduations 650) , takes over at the 600 scale and allows measurement up to 900, thus giving verticality.

Selon une variante,la lecture des angles peut se faire sur le bord droit de la bulle.La graduation commence alors sur ce même bord drcit (dans la Dosition horizontale de l'instrument).Le tube (4) alors,eaX gra- dué de 0 à 600 et le tube (2) de 500 à 900. ( fig 5 )
Dans ce cas, l'horizontalité de l'instrument est atteinte lorsque le bord droit de la bulle (8) du tube (4) est sur la graduation 00.According to a variant, the angles can be read on the right edge of the bubble. The graduation then begins on this same drcit edge (in the horizontal position of the instrument). The tube (4) then, eaX graded from 0 to 600 and the tube (2) from 500 to 900. (fig 5)
In this case, the horizontality of the instrument is reached when the right edge of the bubble (8) of the tube (4) is on the 00 scale.

La verticalité est obtenue, lorsque la bulle (9) du tube (2) es entre les graduations 800 et 30 . Verticality is obtained when the bubble (9) of the tube (2) is between the graduations 800 and 30.

Le dispositif, selon l'invention. est particulièrement destin h la maçonnerie. The device according to the invention. is particularly intended for masonry.

Accouplé à un système simple de visée, il permet de dterminer l'angle de dssnivellation entre deux Doints éloignés. Coupled with a simple sighting system, it makes it possible to determine the angle of descent between two distant Doints.

Par reports successifs du même angle, il permet le maintien d'une pente r4 ulière dans la construction d'ouvrages de maçonnerie de grande longueur ( murs ...etc ) en terrain accidenté et en pente By successive transfers of the same angle, it allows the maintenance of a steep slope in the construction of masonry works of great length (walls ... etc) in uneven and sloping ground
