Abstract

L'invention concerne un instrument de fixation de carénage avec lequel il est facile de fixer/détacher un carénage avant qui recouvre l'avant d'une carrosserie à un cadre d'une bicyclette disponible dans le commerce (ou d'une bicyclette à assistance électrique, d'une bicyclette électrique ou d'un tricycle). Cet instrument de fixation de carénage comprend : une base (1) qui est fixée à un tube de tête ; un moyen de réglage de fixation de base (9) interposé entre la base (1) et un tube supérieur (6) ; un moyen de fixation de base (4) pour fixer la base (1) à un tube de direction (2) d'une bicyclette (16) ; une partie saillante (8) pour fixer un carénage avant (3) à la base (1) ; un moyen de réglage avant-arrière (11) pour régler la position du carénage avant (3) ; une butée de rotation (5) qui prend en sandwich le tube supérieur (6) des deux côtés pour contraindre la direction de fixation de la base (1) ; et un moyen de fixation d'arrêt de rotation (12) pour fixer la butée de rotation (5) et le tube supérieur (6).
