Abstract

Inventia se refra la un mecanism de actionarea fara motor, cu miscare de rotatie a picioarelor, avînd raport de tramnsmitere variabil, destinat actionarii bicicletelor, pedicarelor, hidrobicicletelor etc. Mecanismul de actionare fara motor, cu miscare de rotatie a picioarelor, este alcatuit dintr-o roata de lant eliptica, articulata prin intermediul unor lagare capsulate de niste biele oscilante în jurul unor lagare capsulare amplasate în spatele bratelor de pedala, decalat cu un unghi determinant de 10 degree si niste arcuri care intra în functiune numai atunci cînd forta pe piciorul ciclistului depaseste forta obisnuita corespunzatoare unui rulaj de regim.The invention relies on a non-motorized motion mechanism with a rotational movement of the legs, having a variable transmission ratio, for driving bicycles, pedicures, hydrocycles, etc. The non-motorized rotational movement mechanism of the legs is made up of an elliptical chain wheel, articulated by means of some cams with some oscillating beads around capsular bearings located behind the pedal arms, offset with a determining angle 10th degree and some springs that come into operation only when the force on the cyclist's leg exceeds the usual force corresponding to a regime run.
