Abstract

The invention relates to a miniaturised and self-contained laser apparatus for location and tracing in space. It consists of a cylinder 11 comprising a laser tube 1 excited by a high-voltage power supply 2 and its rechargeable battery 3. A splitter 4 driven by a hollow-rotor motor 5 makes it possible to trace planes perpendicular to the laser beam emitted by the beam 1. Adjustment levels 6 and 7 and a pivot 8 make it possible to adjust precisely along the vertical or the horizontal of the site. Accessories 9 and 10 allow the battery 3 to be recharged. The device according to the invention represented in Figure 1 is in particular intended for tracing in the building trades.

Description

La présente invention concerne un appareil comportant un laser et destiné à des applications d'alignement,de planimétrie,de treçage,de nivellement chaque fois qu'il est nécessaire de définir evec précision et simplicité l'ho rizontalité,la verticalité,la perpendicularité de deux axes ou d'on axe et d'un plan.The present invention relates to an apparatus comprising a laser and intended for applications of alignment, planimetry, tracing, leveling whenever it is necessary to define with precision and simplicity the horizontality, the verticality, the perpendicularity of two axes or one axis and one plane.

De tels dispositifs existent déjà,mais sont constitués par des appareils coûteux et encombrants ,généralement peu maniables.Le dispositif,selon l'invention,permet de remédier à ces trois inconvénients.Such devices already exist, but are constituted by expensive and bulky devices, generally not very manageable. The device according to the invention makes it possible to remedy these three drawbacks.

Il comporte dans un tube métallique (11)cylindrique comme représenté sur la figure j.Un tube laser Héltum-Néon (1) excité par une alimentation (2) à haute tension elle-même alimentée par une batterie rechargeable (3) sont situés dans le tube (11).Le faisceau laser est séparé en deux faisceaux rectilignes perpendiculaires entre eux au moyen d'une séparatrice semi-réfléchissante placée à 45 d'incidence.Cette séparatrice est mise en rotation au moyen d'un moteur (5) qui porte la séparatrice (4).Ce moteur est réalisé de telle façon qu'il n'empêche pas la propagation du faisceau direct,c'est à dire qu'il comporte un rotor crewx.L'appareil peut ainsi émettre un faisceau dans l'axe du cylindre et un faisceau perpendiculaire,qui au cours de la rotation du moteur et de la séparatrice décrit un plan perpendiculaire à l'axe.It comprises in a cylindrical metal tube (11) as shown in FIG. J. A Heltum-Neon laser tube (1) excited by a high voltage power supply (2) itself supplied by a rechargeable battery (3) are located in the tube (11). The laser beam is separated into two rectilinear beams perpendicular to each other by means of a semi-reflecting separator placed at 45 incidence. This separator is rotated by means of a motor (5) which carries the separator (4) .This motor is designed in such a way that it does not prevent the propagation of the direct beam, i.e. it includes a crewx rotor. The device can thus emit a beam into the 'axis of the cylinder and a perpendicular beam, which during the rotation of the engine and the separator describes a plane perpendicular to the axis.

L'appareil comporte en outre un niveau à bulle dit "hori zonal (6) et un niveau à bulle dit "vertical" (7) qui eont inclus dans le tube cylindrique.Il est fixé sur un support d'accrochage (8) qui comporte un système de rotule ou équivalent qui permet de régler l'appareil en situation horizontale ou en situation verticale selon les indications des niveaux (6) ou (7).The apparatus further comprises a so-called "horizontal" spirit level (6) and a so-called "vertical" spirit level (7) which are included in the cylindrical tube. It is fixed on a hanging support (8) which has a ball joint system or equivalent which allows the device to be adjusted horizontally or vertically as indicated in levels (6) or (7).

Un accessoire de recharge (soit par batterie solaire,soit par secteur (9) et (10) ),permet la recharge de la batterie et rend l'appareil autonome.L'appareil objet de l'invention présente ainsi des avantages de compacité,de simplicité d'emploi,d'autonomie et sa réalisation peut être d'un prix avantageux. A recharging accessory (either by solar battery, or by sector (9) and (10)), allows the recharging of the battery and makes the device autonomous. The device object of the invention thus presents advantages of compactness, simplicity of use, autonomy and its realization can be of an advantageous price.
