Abstract

Dispositif de mesure de longueur selon le brevet français principal, pour mesurer ou régler la position relative de deux objets et dont la graduation et l'unité de lecture sont, pour les protéger contre les influences extérieures, abritées dans un corps creux allongé et rigide à la flexion qui est fixé sur l'un des objets précités au moyen d'éléments articulés. Le corps creux 1 est fixé avec l'intercalation d'articulations 5 à surface courbe, de préférence des joints à rotule.Device for measuring length according to the main French patent, to measure or adjust the relative position of two objects and whose graduation and reading unit are, to protect them against external influences, housed in an elongated hollow body and rigid at the flexion which is fixed on one of the aforementioned objects by means of articulated elements. The hollow body 1 is fixed with the intercalation of joints 5 with a curved surface, preferably ball joints.
