Abstract

L'invention concerne un scooter pliable pourvu d'une articulation de pliage et une articulation de pliage correspondante. L'articulation de pliage comprend deux logements d'articulation (11, 12) qui peuvent pivoter l'un par rapport à l'autre sur un axe de pivotement (13), un verrou (14) qui est mobile entre une position de verrouillage et une position de déverrouillage étant prévu qui peut éventuellement coopérer dans une position relative prédéterminée des deux logements d'articulation (11, 12) l'un par rapport à l'autre avec une pièce de verrou homologue au niveau de l'autre logement d'articulation (12) afin de fixer l'articulation pliable. En outre, un levier de serrage (24) est prévu qui est relié par le biais d'une barre à ressort (26) à une barre de traction (27) et par le biais d'un ressort de compression (28) au verrou (14) et qui peut pivoter autour d'un axe de levier de serrage (25) entre une position de verrouillage et une position d'ouverture en via une position de déverrouillage. La barre à ressort (27) s'engage de façon excentrique avec le levier de serrage (24).
