Abstract

L'invention concerne un mécanisme électromécanique pour le contrôle de poids fractionnaires dans une station de musculation, à installer dans une tour de poids de la station de musculation, du type comprenant deux colonnes verticales jointes au sommet par une traverse et, au niveau de la partie inférieure, par une base, et sur laquelle repose une pile de poids unitaires déplaçables verticalement par traction d'un câble d'acier coulissant dans des guides verticaux montés entre la traverse et la base. La tour présente, en son sommet, une poulie qui dévie le câble d'acier provenant de la partie inférieure de la tour vers le centre de cette dernière, où il est fixé aux poids unitaires. La poulie (8), qui dévie le câble d'acier, est montée au centre d'un axe (11). Ledit axe (11) est maintenu en suspension parallèlement à la traverse (2) par une paire de supports (13) fixés à la traverse (2) de la tour. Des poulies (15) montées sur l'axe de chaque côté de la poulie (8) sont pourvues d'un organe d'accouplement (17) latéral pouvant entrer en prise avec un organe d'accouplement (18) d'un disque (19) adjacent monté sur l'axe (11) de manière à pouvoir coulisser longitudinalement et guidé par une tige (20) entraînée axialement par le curseur (23) d'un actionneur linéaire (24). Un câble d'acier (16) est assujetti à chaque poulie (15) et, derrière la tour, passe par une poulie (29) de déviation et descend verticalement à l'intérieur d'un tube (30) fixé à la traverse (2) et à la base (3) de la tour, un poids (31 ou 32) fractionnaire cylindrique étant fixé à l'extrémité dudit câble.
