Abstract

L'invention concerne un dispositif de blocage des cadres avant et arrière d'une bicyclette pliable qui comprend un élément de connexion avant fixé sur le cadre avant, un élément de connexion arrière fixé sur le cadre arrière et un axe pivot assemblant lesdits éléments de connexion avant et arrière, l'élément de connexion arrière étant un tube de blocage présentant une extrémité fermée. Une cheville de blocage est disposée dans ledit tube, un ressort de sollicitation est placé entre ladite cheville de blocage et l'extrémité fermée dudit tube et un orifice de blocage dans lequel peut être insérée la cheville de blocage est ménagé dans ledit élément de connexion avant. Ce dispositif de blocage comprend en outre un tube de direction fixé sur l'essieu central de la bicyclette, un axe placé dans le tube de direction et un levier de pédale fixé sur l'axe. Une fente est pratiquée au niveau de l'extrémité du levier de pédale qui permet de fixer une vis sur la cheville de blocage. La rotation du levier de pédale autour de l'axe entraîne un mouvement de la cheville de blocage par l'intermédiaire de ladite vis afin de bloquer ou débloquer les cadres avant et arrière au moyen des éléments de connexion avant et arrière.
