  • the scope of the present invention is part of the industry sector dedicated to the manufacture of bicycle accessories, particularly focusing on the field of front wheel fixing hubs.
  • a type of fork for the wheel of some vehicles for example for the front wheel of a motorcycle or a bicycle, is known in the current state of the art, instead of two U-arms between whose arms the wheel is attached by fixing with a bushing that crosses respective holes of its ends, they are formed by a single lateral arm whose end derives, perpendicularly, a rod in which the bushing that acts as the axis of rotation is inserted and holds the wheel.
  • said hub is shaped so that, for its removal or placement and the corresponding removal or placement of the wheel, it is necessary to loosen and tighten a screw, to which is necessary to use a specific tool, usually an Alien® wrench or a screwdriver, depending on the type of screw.
  • the aim of the present invention is, therefore, to provide the market with a new type of hub to fix the front bicycle wheels with said type of side forks with which it is not necessary to need any tools and can simply be placed and removed. through the force exerted with a user's hand.

Abstract

L'invention concerne un moyeu de fixation manuelle spécifiquement adapté comme axe de rotation et de fixation d'une roue avant de bicyclette en fourche latérale à un seul bras à travers la jante intérieure (2) de ladite roue équipée d'ailettes (21, 22) au niveau de ses bords respectifs, et comprenant un corps tubulaire (3) réglable à l'intérieur de la jante interne (2), une couronne (31) ménagée d'orifices (32) pour supporter le disque de frein de la roue faisant saillie de chaque extrémité, et ledit corps tubulaire (3) étant caractérisé en ce que son extrémité opposée à celle comportant la couronne (31), présente, au moins, une section filetée (33) dans laquelle se visse un écrou de fixation (4) à serrage manuel qui comprend une partie externe (41) ou distale avec des fentes, lequel reste orienté vers l'extérieur lorsqu'il est vissé dans le corps tubulaire (3), avec un diamètre (d) supérieur au diamètre de l'ailette (21) de la jante interne (2). Le corps tubulaire (3) présente une seconde section filetée (34) mise en place au niveau de la partie intérieure, dans la même extrémité que la première section filetée (33), susceptible de comprendre un boulon de fixation par serrage. L'ailette (21) de la jante intérieure (2) présente une surface externe (23) légèrement inclinée vers l'arrière et comprend un joint torique.
