Title
(EN) FOLDING HANDLEBAR
(FR) GUIDON PLIANT
Abstract
(EN)
Tapered proximal ends of grip ends fit tightly into tapered sockets of a center portion of a folding handlebar such that, in a locked riding position, the handlebar resists any noticeable play or movement transverse to the length of the handlebar. Such provides unusual strength and rigidity in the folding handlebar that rivals fixed, non folding handlebars. Yet, simultaneously, the tapered fit between the grip ends and the tapered sockets of the center portion of the folding handlebar allows relatively easy extraction along the length of the grip ends from the center portion to expose a hinge about which each grip end folds. A small, internal retention pin and an internal retention spring are all that is needed to prevent inadvertent extraction of the grip ends during riding.
(FR)
Selon l'invention, les extrémités proximales d'éléments de préhension sont introduites avec un ajustement serré dans des douilles effilées d'une partie centrale d'un guidon pliant de sorte que, en position bloquée pour l'utilisation du deux-roues, le guidon résiste à tout jeu ou mouvement transversal notable par rapport à la longueur du guidon. Cette conception confère au guidon pliant une résistance et une rigidité inhabituelles par rapport aux guidons fixes, non pliants. Cependant, l'ajustement entre les extrémités de préhension et les douilles effilées de la partie centrale du guidon pliant permet également de retirer relativement facilement les extrémités de préhension au moyen d'un mouvement exercé le long de ces dernières, à partir de la partie centrale, dans le but de dégager un pivot d'articulation autour duquel chaque extrémité de préhension peut pivoter pour être repliée. Une goupille de retenue interne, de faible dimension, et un ressort de retenue interne suffisent à empêcher un retrait intempestif des extrémités de préhension pendant l'utilisation du deux-roues.
