La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un buje de fijación manual que aporta, a la función a que se destina, ventajas y características de novedad que se describirán en detalle más adelante. The invention, as expressed in the present specification, refers to a manual fixing bushing that provides, to the function to which it is intended, advantages and novelty features that will be described in detail below.
El objeto de la presente invención recae, en un buje destinado a constituir el eje de giro desmontable de la rueda delantera de una bicicleta cuya extracción permite desmontar dicha rueda de la horquilla en que se sustenta, el cual, aplicable concretamente a horquillas laterales de un único brazo, se distingue por presentar una configuración estructural que permite el montaje y desmontaje del mismo mediante fijación manual, es decir, sin necesidad de utilizar ningún tipo de herramienta, lo cual supone una gran ventaja para el usuario, ya que permite hacerlo en cualquier momento y lugar de una manera rápida y sencilla. The object of the present invention lies in a hub intended to constitute the removable axis of rotation of the front wheel of a bicycle whose removal allows the said wheel to be removed from the fork on which it is supported, which, specifically applicable to lateral forks of a single arm, it is distinguished by presenting a structural configuration that allows the assembly and disassembly of the same by manual fixation, that is, without the need to use any type of tool, which is a great advantage for the user, since it allows it to be done in any Time and place quickly and easily.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación accesorios para bicicletas, centrándose particularmente en el ámbito de los bujes de fijación de las ruedas delanteras. 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.
ANTECEDENTES DE LA INVENCIÓN Son conocidos en el estado actual de la técnica un tipo de horquillas para la rueda de algunos vehículos, por ejemplo para la rueda delantera de una motocicleta o de una bicicleta que, en lugar de dos brazos en U entre cuyos brazos se incorpora la rueda fijándose con un buje que atraviesa respectivos orificios de sus extremos, están conformadas por un único brazo lateral de cuyo extremo dimana, perpendicularmente, un vástago en el que se inserta el buje que hace de eje de giro y sujeta la rueda. BACKGROUND OF THE INVENTION 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.
El caso es que, hasta ahora, concretamente en el caso de las bicicletas, dicho buje está conformado de manera que, para su extracción o colocación y la correspondiente extracción o colocación de la rueda, es necesario el afloje y apriete de un tornillo, para lo cual es necesario el uso de una herramienta específica, normalmente una llave Alien® o un destornillador, según sea el tipo de tornillo. The case is that, so far, specifically in the case of bicycles, 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.
Ello hace que, en caso de no disponer de dicha herramienta, por las circunstancias que sea, el usuario de la bicicleta no puede extraer o colocar la rueda, lo cual puede suceder muy a menudo, por ejemplo en caso de pinchazo. This means that if the tool is not available, due to the circumstances, the bicycle user cannot remove or place the wheel, which can happen very often, for example in case of a puncture.
El objetivo de la presente invención es, pues, dotar al mercado de un nuevo tipo de buje para fijar las ruedas delanteras de bicicleta con dicho tipo de horquillas laterales con el que no sea necesario precisar de ninguna herramienta y se pueda colocar y extraer simplemente a través de la fuerza ejercida con una mano del usuario. 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.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, al menos por parte del solicitante, se desconoce la existencia de ningún buje de fijación manual o invención de aplicación similar que presente unas características técnicas, estructurales y constitutivas iguales o semejantes a las que presenta el que aquí se reivindica. On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, the existence of no manual fixing bushing or invention of similar application that has the same technical, structural and constitutive characteristics is unknown. or similar to those presented by the one claimed here.
EXPLICACIÓN DE LA INVENCIÓN El buje de fijación manual que la invención propone se configura pues como una novedad dentro de su campo de aplicación, ya que a tenor de su implementación se alcanzan satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible convenientemente recogidos en las reivindicaciones finales que acompañan la presente descripción.
