Abstract

L'invention concerne un dispositif de blocage et de rotation des tubes du cadre d'une bicyclette pliable qui comprend un tube de cadre avant et un tube cadre arrière, deux organes de blocage avant et arrière sont assemblés sur le tube de cadre avant et le tube cadre arrière au moyen de vis, un bras de connexion avant et un bras de connexion arrière sont fixés à demeure sur lesdits organes de blocage avant et arrière et sont assemblés par rotation à l'aide d'une tige d'articulation, une plaque de blocage est fixée sur l'extrémité arrière dudit tube de cadre avant et une plaque de montage est fixée sur l'extrémité avant dudit organe de blocage arrière, sur la plaque de blocage est ménagé un orifice allongé, sur la plaque de montage est fixé à demeure un élément de blocage en forme de T qui s'étend le long du sens axial dudit tube de cadre arrière et qui peut être inséré dans ledit orifice. Lorsque le tube de cadre avant et le tube cadre arrière sont assemblés par rotation autour de la tige d'articulation, ils peuvent être bloqués ou libérés par rotation dudit élément de blocage en forme de T inséré dans ledit orifice en raison de la rotation des bras de connexion avant et arrière autour de l'axe du tube de cadre.
