Abstract

The device is formed by two spirit-levels (2,4) placed, one horizontally, the other vertically, on the drill casing (1). The spirit-levels (2,4) can be fixed or removable. They can have graduations (3,5). When the drill (1) is used in a horizontal plane, the horizontal spirit-level (2) permits the bit (6) either to be perpendicular to the vertical surface (7) or to be kept at a constant angle, by keeping the bubble (8) at a fixed graduation (3). The vertical spirit-level (4) is used in a similar manner when the drill is used in a vertical plane.

Description

L'objet de l'invention concerne un dispositif de contrôle d'orientation de perceuse. The object of the invention relates to a drill orientation control device.

I1 est destiné à etre monté ou incorporé sur les perceuses à main, afin que l'opérateur puisse en cours d'usage maintenir ou corriger le positionnement du foret. I1 is intended to be mounted or incorporated on hand drills, so that the operator can in use maintain or correct the positioning of the drill.

Dans les perceuses courantes l'opérateur pour réaliser des percements quelques soient les traçages, se fiait uniquement sur sa destérité, de sorte que très souvent les forages n ' étaient pas orientés d'une façon exacte, ce qui occasonnait des dégradations sur les surfaces utilisées, car il fallait reprendre le percement et une perte de temps ainsi qu'une usure anormale des forets. In the current drills the operator to carry out bores some are the tracings, relied only on its desterity, so that very often the drillings were not oriented in an exact way, which caused degradations on the surfaces used , because it was necessary to resume drilling and a loss of time as well as abnormal wear of the drills.

Le dispositif suivant l'invention supprime ces inconvénients et permet de réaliser en toutes positions des forages avec une orientation contrôlée et rectifiable en cours d'usage. The device according to the invention eliminates these drawbacks and makes it possible to carry out drilling in any position with a controlled and rectifiable orientation during use.

Il est constitué par la fixation sur le carter extérieur de la foreuse d'un jeu de niveaux gradués, l'un parallèle et l'autre perpendiculaire à ce meme axe, sur une ou deux faces de la perceuse. It is constituted by fixing on the outer casing of the drill a set of graduated levels, one parallel and the other perpendicular to this same axis, on one or two faces of the drill.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'inven- tion:
La figure 1 représente vu en élévation, le positionnement des niveaux gradués.In the appended drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention:
Figure 1 shows in elevation, the positioning of the graduated levels.

Les figures 2 et 3 montrent les applications du dispositif. Figures 2 and 3 show the applications of the device.

La foreuse 1 comporte sur la face externe de son carter un niveau horizontal 2, avec graduations 3, et un niveau vertical 4 également gradué 5. The drilling machine 1 has on the external face of its casing a horizontal level 2, with graduations 3, and a vertical level 4 also graduated 5.

L 'opérateur peut ainsi maintenir l'orientation du foret 6. The operator can thus maintain the orientation of the drill 6.

Lorsque la perceuse est utilisée dans un plan horizontal, le niveau 2, Fig 2 permet de maintenir le foret soit perpendiculaire à la surface 7, soit avec une inclinaison déterminée en maintenant la bulle 8 au degré 3 voulu. When the drill is used in a horizontal plane, level 2, Fig 2 makes it possible to maintain the drill either perpendicular to the surface 7, or with a determined inclination while maintaining the bubble 8 at the desired degree.

Par contre, lorsque la perceuse fig 3 est utilisée dans un plan vertical, le niveau 5 permet le contrôle permanent de la rectitude du forage. Par contre, la bulle 9 donne la possibilité de maintenir une inclinaison déterminée sans possibilité de variation.  On the other hand, when the drill fig 3 is used in a vertical plane, the level 5 allows the permanent control of the straightness of the drilling. On the other hand, the bubble 9 gives the possibility of maintaining a determined inclination without the possibility of variation.

Par cette application nouvelle de deux niveaux combinés, on assure à donner aux perceuses à main, ainsi qu'à tous appareils du meme genre, telles les perceuses, les scies,une précision qu' elles n'auraient jamais eu et dont l'usage régulier dépendant uniquement de l'habileté de l'opérateur. Ces niveaux peuvent être, soit intégrés, soit amovibles. By this new application of two combined levels, we assure to give to hand drills, as well as to all devices of the same kind, such as drills, saws, a precision that they would never have had and whose use regular depending only on the skill of the operator. These levels can be either integrated or removable.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents, comme d ' ailleurs les types de niveaux utilisés sans changer pour cela la conception générale de l'invention qui vient d'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as indeed the types of levels used without changing the general conception of the invention which has just been described.
