Abstract

L'invention concerne des perfectionnements apportés au dispositif d'articulation faisant l'objet du brevet principal. Dans chaque jambe, la tirette est remplacée par une butée 15 montée pivotante à l'extrémité supérieure de la jambe 3 et sollicitée par un ressort 33 en direction des butées latérales 35, 37, 39 du support 1, de façon à s'encliqueter dans l'une d'elles, son dégagement s'obtenant par pression du doigt sur la butée pivotante à l'encontre de la force du ressort. Matériel photographique et cinématographique.
