Title
(EN) PARALLELISM ADJUSTMENT MECHANISM FOR LOAD BALANCING ARM
(FR) MÉCANISME DE RÉGLAGE DE PARALLÉLISME POUR BRAS D'ÉQUILIBRAGE DE CHARGE
Abstract
(EN) A load balancing arm (20) for a medical device support system includes a proximal hub (22, 120, 114), a support arm (50), a link (90), and a distal end vertical block (112). The components together form a four bar linkage. The proximal hub is configured for pivotable movement about an axis P-P. A distal hub (122) is configured to support a medical device load for pivotable movement about an axis D-D. The distal hub (122) is mounted to the distal end vertical block(112) for pivotable movement between a first position in which the axis D-D is at a first angle relative to the axis P-P and a second position in which the axis D-D is at a second angle relative to the axis P-P, wherein the first angle is different than the second angle. A parallelism adjustment mechanism enables the axis D-D to be adjusted so as to be substantially parallel to the axis P-P.
(FR) Un bras d'équilibrage de charge (20) pour un système de support de dispositif médical comprend un moyeu proximal (22, 120, 114), un bras de support (50), une liaison (90) et un bloc vertical d'extrémité distale (112). Les éléments peuvent former conjointement une liaison à quatre barres. Le moyeu proximal est conçu pour effectuer un mouvement pivotant autour d'un axe P-P. Un moyeu distal (122) est conçu pour supporter une charge de dispositif médical pour un mouvement pivotant autour d'un axe D-D. Le moyeu distal (122) est monté sur le bloc vertical d'extrémité distale (112) pour effectuer un mouvement pivotant entre une première position dans laquelle l'axe D-D est à un premier angle par rapport à l'axe P-P et une seconde position dans laquelle l'axe D-D est à un second angle par rapport à l'axe P-P, le premier angle étant différent du second angle. Un mécanisme de réglage de parallélisme permet de régler l'axe D-D de manière à être sensiblement parallèle à l'axe P-P.
