Abstract

Abstract Translated from French L'INVENTION CONCERNE UN DISPOSITIF DE CHANGEMENT DE VITESSE POUR UNE BICYCLETTE POURVU D'UN ORGANE DE BASE FIXE AU CADRE DE LA BICYCLETTE ET DE PREMIER ET SECOND LEVIERS DE MANOEUVRE SUPPORTES ROTATIFS DES DEUX COTES DE L'ORGANE DE BASE. SELON L'INVENTION, L'ORGANE DE BASE EST POURVU D'UN CORPS ET DE DEUX TIGES2, 3 QUI S'ETENDENT VERS L'EXTERIEUR DES DEUX COTES DU CORPS, LES LEVIERS4, 5 AYANT DES PROTUBERANCES4A, 5A SUPPORTEES ROTATIVES SUR LES TIGES ET DES PARTIES DE MANOEUVRE4B, 5B QUI S'ETENDENT RADIALEMENT VERS L'EXTERIEUR DES PROTUBERANCES RESPECTIVEMENT, LES PARTIES DE MANOEUVRE AYANT A L'INTERIEUR DE LEURS PARTIES OPPOSEES, DES PARTIES RENFLEES41, 51, GONFLEES VERS L'INTERIEUR AU-DELA DES COTES LATERAUX DE L'ORGANE DE BASE RESPECTIVEMENT. L'INVENTION S'APPLIQUE NOTAMMENT A L'INDUSTRIE DU CYCLE. THE INVENTION CONCERNS A GEAR CHANGE DEVICE FOR A BICYCLE PROVIDED WITH A BASE ORGAN FIXED TO THE FRAME OF THE BICYCLE AND FIRST AND SECOND ROTARY SUPPORTED MANEUVER LEVERS ON BOTH SIDES OF THE BASE ORGAN. ACCORDING TO THE INVENTION, THE BASE ORGAN IS PROVIDED WITH A BODY AND TWO RODS2, 3 WHICH EXTEND OUTWARD ON BOTH SIDES OF THE BODY, THE LEVERS4, 5 WITH PROTUBERANCES4A, 5A ROTATING SUPPORTS ON THE RODS AND OPERATING PARTS4B, 5B WHICH EXTEND RADIALLY OUTSIDE OF THE PROTUBERANCES RESPECTIVELY, THE OPERATING PARTS HAVING INSIDE THEIR OPPOSED PARTS, BULLED PARTS41, 51, INFLATED INTO THE INSIDE BEYOND LATERALS OF THE BASE BODY RESPECTIVELY. THE INVENTION APPLIES IN PARTICULAR TO THE CYCLE INDUSTRY.
