Abstract

Un système à bras oscillants comprend au moins deux bras oscillants (6, 10; 51, 52) orientables au moins sur un plan situé au-dessus d'une articulation (1, 50) agencée entre les deux et susceptibles d'être bloqués au-dessus d'un dispositif d'arrêt (20, 90). Afin d'obtenir un blocage complètement rigide dans pratiquement n'importe quel angle et agencement, il est prévu de former le dispositif d'arrêt (20, 90) entre les deux bras oscillants (6, 10; 51, 52) comme une fermeture géométrique déverrouillable et de pourvoir une des deux moitiés de l'articulation (9a, 9b; 58, 59) d'une pluralité de subdivisions de précision coopérant avec la fermeture géométrique afin de former une pluralité d'angles d'orientation entre les deux bras oscillants (6, 10; 51, 52).
