Description

ACCESORIO PARA RUEDAS NEUMÁTICAS  ACCESSORY FOR PNEUMATIC WHEELS
D E S C R I P C I Ó N OBJETO DE LA INVENCIÓN D E S C R I P C I O N OBJECT OF THE INVENTION
La presente invención se refiere a un accesorio para ruedas neumáticas, en particular para ruedas de bicicletas y similares. El accesorio está destinado a ocupar la cámara o espacio definido entre la llanta y la cubierta de la rueda, siendo el objeto de la invención mejorar las prestaciones de la rueda en su conjunto, en particular disminuyendo drásticamente el riesgo de pinchazo, entre otra serie de ventajas a las que se aludirá mas adelante. The present invention relates to an accessory for pneumatic wheels, in particular for bicycle wheels and the like. The accessory is intended to occupy the defined chamber or space between the rim and the wheel cover, the object of the invention being to improve the performance of the wheel as a whole, in particular drastically reducing the risk of puncture, among other series of advantages that will be mentioned later.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido, las ruedas neumáticas están estructuradas mediante una llanta metálica, convenientemente fijada al eje de la rueda, llanta que requiere perimetral y exteriormente una cubierta de un material elastomérico, generalmente un derivado de caucho, estableciéndose entre llanta y cubierta una cámara estanca, presurizada, que actúa como amortiguador al desplazarse la rueda sobre el suelo, adaptándose a las irregularidades de éste último. As is known, the pneumatic wheels are structured by means of a metal rim, conveniently fixed to the wheel axle, a tire that requires perimeter and externally a cover of an elastomeric material, generally a rubber derivative, establishing a sealed chamber between the rim and cover, pressurized, which acts as a shock absorber when the wheel moves on the ground, adapting to the irregularities of the latter.
Con independencia de la posible existencia sobre el suelo de elementos punzantes o cualquier otro tipo de elementos capaces de dañar la rueda, son relativamente frecuentes los pinchazos ante lo que comúnmente se denomina un "llantazo", es decir un golpe brusco de la llanta contra el suelo, ya que en tales circunstancias se produce un desplazamiento del aire en el seno de la cámara estanca y el pinchazo se produce por pinzado del neumático o cubierta entre la llanta y el suelo. Regardless of the possible existence on the ground of puncturing elements or any other type of elements capable of damaging the wheel, the punctures are relatively frequent before what is commonly called a "tire", that is to say a sharp blow of the tire against the soil, since in such circumstances there is an air displacement inside the waterproof chamber and the puncture is produced by clamping the tire or cover between the tire and the ground.
Este desplazamiento instantáneo del aire en el interior de la cámara y la deformabilidad de la propia cubierta, traen consigo una cierta facilidad de que se produzcan resbalones en curvas y en subidas empinadas, repercutiendo por otro lado negativamente en las frenadas. This instantaneous displacement of the air inside the chamber and the deformability of the roof itself, bring with it a certain ease of slipping in curves and steep climbs, having a negative impact on braking.
DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION
El accesorio para ruedas neumáticas que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados. Para ello y de forma mas concreta, dicho accesorio se materializa en un cuerpo toroidal, de espuma de poliuretano, dimensionalmente adecuado para rellenar la cámara estanca definida entre llanta y cubierta, de manera que aunque el aire con el que se presuriza dicha cámara se siga desplazando en el interior de la misma desde la zona de apoyo al resto de la rueda, el citado cuerpo de espuma de poliuretano mantiene sustancialmente independizadas llanta y cubierta, permitiendo la deformación de ésta última, pero sin llegar ni mucho menos a los límites de una rueda convencional sin tal accesorio. Las ventajas que trae consigo la invención, además de la drástica limitación, prácticamente desaparición del riesgo de pinchazo por llantazo, son, entre otras, las siguientes: The accessory for pneumatic wheels that the invention proposes solves in a completely satisfactory way the problem previously stated, in the different aspects mentioned. For this and more specifically, said accessory is embodied in a toroidal body, made of polyurethane foam, dimensionally suitable for filling the sealed chamber defined between the tire and tire, so that although the air with which said chamber is pressurized is followed moving inside the same from the support area to the rest of the wheel, the aforementioned polyurethane foam body keeps the tire and tire substantially independent, allowing deformation of the latter, but without reaching the limits of a Conventional wheel without such an accessory. The advantages that the invention brings, in addition to the drastic limitation, virtually disappearance of the risk of puncture by tire, are, among others, the following:
Permite la utilización de una menor presión en el neumático. - Mejora la tracción en subidas empinadas con terreno suelto, tanto en lo que se refiere al agarre frontal como al agarre lateral. Allows the use of lower tire pressure. - Improves traction on steep climbs with loose terrain, both in terms of the front grip and the side grip.
- Mejora la seguridad del paso por curvas, evitando resbalones.  - Improves the safety of passing through curves, avoiding slips.
- Se adapta al terreno con independencia de la naturaleza de éste último, ya que permite una deformación instantánea que copia las irregularidades del mismo.  - It adapts to the terrain regardless of the nature of the latter, since it allows an instantaneous deformation that copies its irregularities.
- Mejora la frenada debido a que la cubierta neumática no rebota por la presencia del cuerpo de poliuretano.  - Improves braking because the pneumatic tire does not bounce due to the presence of the polyurethane body.
- Gracias a una menor vibración debida al contacto del neumático con el suelo, minimiza en un alto porcentaje la fatiga muscular. DESCRIPCIÓN DE LOS DIBUJOS  - Thanks to less vibration due to the tire's contact with the ground, it minimizes muscle fatigue by a high percentage. DESCRIPTION OF THE DRAWINGS
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente: To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. In an illustrative and non-limiting manner, the following has been represented:
La figura 1.- Muestra, según una vista en perspectiva, un accesorio para ruedas neumáticas realizado de acuerdo con el objeto de la presente invención. Figure 1 shows, according to a perspective view, an accessory for pneumatic wheels made in accordance with the object of the present invention.
La figura 2.- Muestra, también según una vista en perspectiva, el citado accesorio en situación inicial de montaje sobre la correspondiente rueda, en este caso una rueda de bicicleta. La figura 3.- Muestra un detalle en sección transversal del conjunto de la figura anterior, debidamente montado. REALIZACIÓN PREFERENTE DE LA INVENCIÓN Figure 2.- Shows, also according to a perspective view, the said accessory in initial mounting situation on the corresponding wheel, in this case a bicycle wheel. Figure 3.- Shows a detail in cross section of the assembly of the previous figure, properly assembled. PREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas puede observarse como el accesorio que la invención propone consiste en un cuerpo toroidal (1), es decir un cuerpo anular de sección circular, obtenido a base de espuma de poliuretano, cuerpo toroidal cuyo diámetro es acorde con el diámetro de la rueda (2) a que se destina, teniendo en cuenta que está destinado a ocupar la cámara estanca definida entre la llanta (3) y la cubierta (4) de dicha rueda (2). Aunque preferentemente la sección de dicho cuerpo toroidal (1) será circular, como anteriormente se ha dicho, es factible que la sección adopte otra configuración, como por ejemplo copiando con exactitud el perfil de la cámara definida entre la llanta (3) y la cubierta (4). La naturaleza esponjosa del poliuretano constitutivo del accesorio, permite el acceso del aire a su interior, de manera que la rueda en su conjunto puede ser presurizada, como cualquier rueda convencional carente del accesorio, a través de la clásica válvula de inflado (5). En cualquier caso, el cuerpo toroidal (1) actuará como elemento elástico amortiguador, trabajando en paralelo con el aire presurizado de la cámara de la rueda, en la absorción de esfuerzos generados por las irregularidades del suelo durante su recorrido y por el propio peso que las ruedas deben soportar. In view of the aforementioned figures, it can be seen how the accessory proposed by the invention consists of a toroidal body (1), that is to say an annular body of circular section, obtained based on polyurethane foam, toroidal body whose diameter is in accordance with the diameter of the wheel (2) to which it is intended, taking into account that it is intended to occupy the sealed chamber defined between the rim (3) and the cover (4) of said wheel (2). Although preferably the section of said toroidal body (1) will be circular, as previously stated, it is feasible that the section adopts another configuration, such as by accurately copying the profile of the defined chamber between the rim (3) and the cover (4). The spongy nature of the accessory polyurethane, allows access to the air inside, so that the wheel as a whole can be pressurized, like any conventional wheel lacking the accessory, through the classic inflation valve (5). In any case, the toroidal body (1) will act as an elastic damping element, working in parallel with the pressurized air of the wheel chamber, in the absorption of stresses generated by the irregularities of the ground during its travel and by the weight itself The wheels must support.
