摘要:
La présente invention a pour objet un plateau non circulaire pour pédalier. Il est constitué par un plateau (1) de pédalier permettant de faire augmenter progressivement le couple de pédalage depuis le point mort jusqu'au point où l'extension de la jambe permet de fournir l'effort maximum, grâce à une variation progressive du rayon primitif de la denture entre ces deux points, suivie d'une décroissance rapide jusqu'au point mort suivant. Le principe étant tel que la force à fournir est proportionnelle à la force musculaire que l'utilisateur peut fournir. Elle concerne principalement l'industrie du cycle mais peut trouver des applications dans d'autres domaines, par exemple celui des appareils d'exercices physiques pour la musculation ou la rééducation, et en général pour tous les appareils utilisant le pédalage et un système de transmission par chaîne ou courroie entre le ou les plateaux du pédalier et un ou plusieurs pignons actionnant le dispositif à entraîner.

The invention concerns a device in particular for use in the field of sport practice and body-building, for a person's muscular exercise. Said device enables the development of quadriceps and of the gluteal muscles and comprises a support surface for the feet and means for applying a force of resistance to the movements of the person's legs to shift from a bent position to an extending position by unfolding the knees. The invention is characterised in that the force applying means comprise a harness pressing on the upper side of the thighs. The invention is applicable to the manufacture of body-building machine.

摘要:
The non-circular front chain wheel for crank gear is comprised of a crank gear wheel (1) allowing to increase progressively the cycling torque from the dead point up to the point where the extension of the leg allows to create the maximum effort, due to a progressive variation of the primitive radius of the toothing between these two points, followed by a rapid decrease to the next dead point. The principle is that the force to be provided is proportional to the muscular force that the user may provide. It essentially concerns the cycle industry but may also find applications in other fields, for example physical exercisers for body-building or reeducation, and in general all apparatuses utilizing the cycling motion and a chain or belt transmission system between the front wheel or wheels of the crank gear and one or a plurality of pinions actuating the device to be driven.
