Title (EN) CRANKSET DEVICE
(FR) DISPOSITIF POUR PEDALIER
Abstract: front page image
(EN)To understand the present invention, it is first necessary to understand thoroughly the following discovery concerning the calf when pressure is applied on the pedal: there are two optical illusions which mislead everyone (figures 21 and 22 represent a lower limb pressing on a pedal, (6) being the thigh, (11) the leg, A+B the foot and (1) the ankle). The first illusion (fig 21) is to believe that the calf (M) increases the pressure on the pedal. The second illusion (fig 22) is not to see the force M' which cancels the force M. The entire pressure on the pedal is derived from the thigh only, the calf contraction being merely loss of energy. The invention consists in replacing the pedal by a mechanism avoiding the use of the calf thereby doubling performance without loss of power.
(FR)Pour comprendre cette invention, il faut commencer par comprendre en profondeur la découverte suivante qui concerne le mollet quand on appuie sur une pédale, deux illusions d'optique trompant le monde entier (les fig 21 et 22 symbolisent un membre inférieur appuyant sur une pédale, (6) étant la cuisse, (11) la jambe, A+B le pied et (1) la cheville). La 1ère illusion (fig 21) est de croire que le mollet (M) augmente la pression sur la pédale. La deuxième illusion (fig 22) est de ne pas voir la force M' qui annule la force M. La totalité de la pression sur la pédale provient de la cuisse seulement, la contraction du mollet étant une perte d'énergie. L'invention consiste à remplacer la pédale par un mécanisme permettant d'éviter l'usage du mollet ce qui multiplie par deux le rendement sans perte de puissance.
