Title (EN) DEVICE FOR DISPLACING AND POSITIONING AN ELEMENT IN SPACE
(FR) DISPOSITIF POUR LE DEPLACEMENT ET LE POSITIONNEMENT D'UN ELEMENT DANS L'ESPACE
Abstract:
(EN) The device comprises a base element (1) and a movable element (8). Three control arms (4) are rigidly mounted at their first extremity (15) on three shafts (2) which may be rotated. The three assemblies each formed by a shaft (2) and an arm (4) are the movable parts of three actuators (13) of which the fixed parts (3) are integral with the base element. The other extremity (16) of each control arm is made integral with the movable element through two linking bars (5a, 5b) hingedly mounted on the one hand to the second extremity (16) of the control arm and, on the other hand, to the movable element. The inclination and the orientation in the space of the movable element remain unchanged, whatever the motions of the three control arms may be. The movable element supports a working element (9) of which the rotation is controlled by a fixed motor (11) situated on the base element. A telescopic arm (14) connects the motor to the working element.
(FR) Le dispositif comporte un élément de base (1) et un élément mobile (8). Trois bras de commande (4) sont montés de façon rigide à leur première extrémité (15) sur trois axes (2) qui peuvent être mis en rotation. Les trois ensembles axe (2) - bras (4) constituent les parties mobiles de trois actionneurs (13) dont les parties fixes (3) sont solidaires de l'élément de base. L'autre extrémité (16) de chaque bras de commande est rendue solidaire de l'élément mobile par l'intermédiaire de deux barres de liaison (5a, 5b) montées en articulation, d'une part, sur la seconde extrémité (16) du bras de commande et, d'autre part, sur l'élément mobile. L'inclinaison et l'orientation dans l'espace de l'élément mobile restent inchangés, quels que soient les mouvements des trois bras de commande. L'élément mobile supporte un élément de travail (9) dont la rotation est commandée par un moteur fixe (11) situé sur l'élément de base. Un bras télescopique (14) relie le moteur à l'élément de travail.
