Abstract

L'invention concerne un mécanisme à pédale à levier articulé, utilisé en tant que mécanisme délivrant une puissance utile élevée dans les presses manuelles et dans les cisailles à métaux, pouvant développer une force élevée d'entraînement à partir d'une pédale par élimination du problème rencontré avec un dispositif d'entraînement classique, à savoir qu'une puissance utile délivrée par une force de dépression exercée sur une pédale est physiquement moins importante. L'invention concerne donc un dispositif de pédale permettant d'obtenir une puissance utile élevée grâce à un dispositif différentiel à engrenages logé dans la partie fixe du mécanisme à levier articulé, connectant un dispositif de liaison à une partie coulissante. Elle concerne aussi un dispositif de pédale permettant de développer une puissance utile élevée à l'extrémité coulissante de ce dispositif par fixation d'une partie coudée de renvoi à un corps en installant la partie différentielle d'engrenages dessus, et par établissement d'une traction entre un élément court du renvoi et un levier articulé, ce qui permet de d'obtenir une puissance utile et une capacité élevées dans un concept de développement de bicyclette ainsi qu'un déplacement grâce à l'énergie humaine inenvisageables avant cette invention. L'invention concerne enfin un dispositif de déplacement sur l'eau formé par connexion d'un mécanisme extensible à liaison articulée, possédant une structure d'amplification potentielle, par exemple un pantographe, au mécanisme de pédale et mise en place d'une liaison mécanique d'entraînement avec un dispositif de pagaies.
