Abstract

Ce dispositif de commande de mécanisme (100) est pourvu d'un boîtier interne (104) dans lequel a été ménagée une fente (108). Une poignée de commande (102) renferme une glissière cunéiforme (106) et entoure une partie du boîtier interne autour duquel elle peut tourner. Un piston (110) est positionné coulissant dans le boîtier interne (104), ce piston étant pourvu d'une cheville (112) sur l'une de ses extrémités. Cette cheville (112) vient se placer dans la fente (108) du boîtier interne (104) ainsi que dans la glissière (106) de la poignée de commande (102). Un câble de commande (114) destiné à agir sur le mécanisme est relié au piston (110). Celui-ci et, par conséquent, le câble de commande (114) se déplacent à l'intérieur du boîtier interne (104) lorsque la poignée de commande (102) tourne autour du boîtier interne (104). Il est possible d'installer plus d'une commande dans le dispositif (100). Ce mécanisme peut commander un frein ou un changement de vitesses d'une bicyclette.
