Patent

CA 2318841

A generator (3) mounted within the tread portion (2) of a pedal (20) of a bicycle or the like is driven via pulleys (4) and (5) of unequal diameter and a gear box (7) so that the speed of rotation of the rotor of the generator is a multiple of the speed of relative rotation between the spindle (1) of the pedal and the tread portion (2) when the latter is held horizontal by a foot resting on it and the crank (not shown) from which the spindle (1) extends is rotated to propel the bicycle. The gearing up of the generator enables sufficient output voltage to illuminate an array (9) of LEDs and charge a capacitor (8) which will keep then illuminated while the pedal is temporarily stationary.

Un générateur (3) monté à l'intérieur de la partie appui (2) d'une pédale (20) de bicyclette, par exemple, est entraîné par l'intermédiaire de poulies (4) et (5) de diamètre inégal et d'une boîte d'engrenage (7), de sorte que la vitesse de rotation du rotor du générateur est un multiple de la vitesse de rotation relative entre l'axe (1) de la pédale et la partie appui (2), quand cette dernière est maintenue à l'horizontale par un pied en appui, et que la manivelle (non illustrée) depuis laquelle l'axe de la pédale s'étend, est mise en rotation afin de propulser la bicyclette. La mise en service du générateur sous l'effet du pédalage permet à une tension de sortie suffisante d'éclairer un ensemble (9) de diodes électroluminescentes et de charger un condensateur (8) qui en conservera l'éclairage, tandis que la pédale est fixe temporairement.
