CA 2578971

A resistance exercise machine has a frame that includes a base on the floor and upright posts on the base. Resistance packs mounted for adjustment up and down on the posts are equipped with cams that compensate for the increased resistance resulting from increasing deformation of the resistance elements in the packs. The resistance packs are interconnected by teeth on their rims which allow the packs to be arranged in a stack. An adjustable bench and seat are provided. One alternative is a direct drive system having angularly adjustable levers. Another alternative has a fixed number of resistance packs that can be selectively activated to add resistance.

Cette invention concerne un banc de musculation contre résistance comprenant un cadre avec socle reposant sur le sol et des montants verticaux fixés au socle. Des masses résistantes montées pour ajustement vertical sur les montants sont équipées de cames permettant de compenser l'augmentation de résistance accrue provenant de la déformation croissante des rangées d'éléments de résistance. Les rangées de masses résistantes sont interconnectées par des dents à leur périphérie, ce qui permet de les disposer en rangées. L'appareil est doté d'un banc et d'un siège réglables. En variante, l'invention concerne un système à entraînement direct doté de leviers à réglage angulaire. Dans d'autres versions, on trouve un nombre fixe de masses résistantes que l'on sollicite sélectivement pour accroître la résistance.
