Abstract

The pneumatic reinforcement system for bicycle frames consists in insufflating air or a gas fluid inside the tubes (3,4) or parts which form the frame (2) of the bicycle, so as to exert a constant pressure on the walls of the frame structure. Two forms of application are defined: 1) using walls (b) or membranes which define one or a plurality of fluid-tight chambers for holding the gas. 2) Introducing the air or gas into one or a plurality of elastic chambers (f) which are, in turn, introduced in the hollow interior of the frame structure so as to transmit the pressure to the walls of the frame.

Description

SISTEMA DE REFUERZO NEUMÁTICO PMHA CUADROS DE BICICLETA PMHA PNEUMATIC REINFORCEMENT SYSTEM
DESCRIPCIÓN La presente invención, se refiere a un sistema de refuerzo neumático para cuadros de bicicletas, y se ha desarrollado con particular atención a su posible aplicación a los cuadros de bici¬ cletas de competición.DESCRIPTION The present invention relates to a pneumatic reinforcement system for bicycle frames, and has been developed with particular attention to its possible application to racing bike frames.
Los cuadros de bicicletas, están formados tradicionalmente por una estructura de tubos de sección circular u ovalada, cuya función principal, ademas de servir de enlace entre las distintas partes de la bicicleta, es la de aportar la rigidez necesaria, para soportar el peso y las fuerzas que el ciclista ejerce indi¬ rectamente sobre este.The bicycle frames, are traditionally formed by a structure of circular or oval section tubes, whose main function, in addition to serving as a link between the different parts of the bicycle, is to provide the necessary rigidity, to support the weight and forces that the cyclist indirectly exerts on it.
Puesto que un cuadro, al flexar por falta de rigidez, absor¬ be parte de la energía que el ciclista deberla transmitir a la rueda, el problema fundamental en la fabricación de cuadros de bicicleta, es el encontrar una solución de compromiso entre la rigidez, que aumenta conforme lo hace el grosor de las paredes y uniones de los tubos, y el peso, que de igual manera aumenta en proporción directa a este grosor, y que de forma idónea, debe ser lo más bajo posible. Asi, los materiales empleados en la fabricación de cuadros, evolucionan bajo la idea de conseguir una relación alta rigidez-bajo peso cada vez mejor. Otra tendencia, es aumentar la sección de los tubos disminuyendo el grosor de su parad; enta procedimiento tiene el inconveniente de que la pared se deforma o rompe más fácilmente ante golpes o presiones localizadas.Since one frame, when flexing due to lack of rigidity, absorbs part of the energy that the cyclist should transmit to the wheel, the fundamental problem in the manufacture of bicycle frames is to find a compromise solution between the stiffness, which increases as the thickness of the walls and joints of the tubes, and the weight, which also increases in direct proportion to this thickness, and that in an ideal way, should be as low as possible. Thus, the materials used in the manufacture of frames, evolve under the idea of getting a high rigidity-low weight ratio better and better. Another trend is to increase the section of the tubes by decreasing the thickness of their stop; This procedure has the disadvantage that the wall deforms or breaks more easily in the face of localized shocks or pressures.
El sistema de refuerzo neumático que se presenta, tiende a aumentar la rigidez y resistencia a la deformación de los cuadras de bicicleta, aportando un peso mini o, que puede verse revσsado por el que se restβria, al eliminar material que con este fin se emplea, engrosando los tubos y sus piezas o puntos de unión.The pneumatic reinforcement system that is presented tends to increase the stiffness and resistance to deformation of the bicycle blocks, providing a mini weight or, which can be checked by the rest, by eliminating material that is used for this purpose , thickening the tubes and their parts or attachment points.
HOJA SUSTITUIDA Consiste en insuflar aire, o un fluido gaseoso, hasta comprimirlo en el interior hueco de los tubos y uniones que conforman la estructura del cuadro. El interior de dicha estruc¬ tura, ha sido previamente dispuesto para formar o contener una O varias cámaras herméticas, que quedaran cerradas, una vez la presión interna alcance un punto determinado. Esta presión inter¬ na constante, determina un incremento en la rigidez del cuadro, o la zona de este donde se aplique el sistema.SUBSTITUTED SHEET It consists of insufflating air, or a gaseous fluid, until compressed into the hollow interior of the tubes and joints that make up the structure of the frame. The interior of said structure has been previously arranged to form or contain one or several sealed chambers, which will be closed, once the internal pressure reaches a certain point. This constant internal pressure determines an increase in the stiffness of the frame, or the area of the frame where the system is applied.
En función al modo en que podemos disponer esta o estas cámaras herméticas se definen dos formas de aplicar el sistema. En la siguiente descripción, y con referencia a los dibujos esquemáticos anexas, se exponen dos ejemplos básicos que descri¬ ben estas dos formas de aplicación.Depending on the way in which we can arrange this or these hermetic chambers, two ways of applying the system are defined. In the following description, and with reference to the attached schematic drawings, two basic examples are described that describe these two forms of application.
La figura 1, representa la sección longitudinal de un tubo, en la que hemos aislado herméticamente una cámara (A), mediante paredes o membranas (b) sólidamente unidas al tubo. El aire o fluido gaseoso se insufla a través de un orificio que puede ser interior (c), o exterior al tubo (d). Una válvula, alojada en dicho orificio (e), se cerrara una vez alcanzada la presión deseada, y se retire el dispositivo de insuflado. Las flechas representan gráficamente las fuerzas constantes que resultan de la presión interna.Figure 1 represents the longitudinal section of a tube, in which we have hermetically isolated a chamber (A), by walls or membranes (b) solidly attached to the tube. The air or gaseous fluid is blown through a hole that can be inside (c), or outside the tube (d). A valve, housed in said hole (e), will close once the desired pressure has been reached, and the insufflation device is removed. The arrows graphically represent the constant forces that result from internal pressure.
En la figura 2 se representa la segunda forma de aplica¬ ción definida para el sistema. Una cámara elástica (f) en el interior del tubo, que una vez hinchada se adaptara a la forma interna de este, servirá a fin de contener el aire o compuesto gaseoso, y transmitir su presión a las paredes con las que con¬ tacta. Al igual que en el ejemplo anterior la válvula (β) de entrada o salida d« gases, puede ser interior o exterior al tubo, Es de resaltar, αue las zonas de la cámara elástica, que como consecuencia de su forma, o el grosor de su pared, tpngnn una mayor O menor tend ncia a hincharse, o a albergar más 6 me-Figure 2 shows the second form of application defined for the system. An elastic chamber (f) inside the tube, which once swollen will adapt to its internal shape, will serve to contain the air or gaseous compound, and transmit its pressure to the walls with which it contacts. As in the previous example, the gas inlet or outlet valve (β) may be inside or outside the tube. It should be noted that it is the areas of the elastic chamber, which as a consequence of its shape, or the thickness its wall, t p NGNN more or less tend to swell nce or more host 6 Me-

This effect can be beneficially exploited by modifying the elastic chamber externally, so that it exerts greater pressure on the areas of the structure that require greater rigidity; and vice versa.
A modo de ejemplo no limitativo, la figura 3 representa gráficamente una forma ds ejecución del sistema, según la pri¬ mera forma de aplicación definida. La caja de pedaliβr (l), ha sido aislada y desplazada de su posición habitual, de manera que el aire puede fluir entre las vainas (2), y los tubos ver¬ tical (3j y oblicuo (4). Dos paredes (bj, sólidamente ins¬ taladas por procedimientos de soldadura o pegado, delimitan una cámara, cerrándola herméticamente. Mediante una bomba O inyector, y a travββ de una válvula (• ), insuflaremos el aire en la cámara. Dicha válvula, esta situada en un punto, en el que no dificulta la acción del ciclista, ni la colocación o función de las piezas o accesorios de la bicicleta. La presión interna, que puede ser medida mediante un manómetro, deberá ser tal, que aumente de forma considerable la rigidez de la zona, sin hacer peligrar Ira integridad de la estructura. En las figuras 4, 5 y 6, se representan otras soluciones, en las que conductos u orificios (5) que permiten el paso del aire, se encargan de conectar las presiones de los tubos. El segundo método de 'aplicación descrito, se representa en un ejemplo de su ejecución no limitativo, en la figura 7. En esta ocasión, se ha modificado un cuadro para contener una cámara elástica que debe hincharse en su interior. Tanto la caja de pedalier (lj, como el espacio que requieren la tija de sillín (.6), y el sistema de dirección (?.), han sido aislados y desplazados de su posición habitual para permitir un aloja¬ miento idóneo para dicha cámara elástica. Las esquinas de las paredes interiores, tienen una forme redondΞada para adaptarse mejor a la cámara elástica sin romperla o deteriorarla. Convie¬ ne que el interior del cuadro este ligeramente lubricado para facilitar el deslizamiento y correcto posicionamiento de laBy way of non-limiting example, Figure 3 graphically depicts a system execution form, according to the first defined application form. The pedaliβr box (l) has been isolated and displaced from its usual position, so that air can flow between the pods (2), and the vertical tubes (3j and oblique (4). Two walls (bj , solidly installed by welding or gluing procedures, delimit a chamber, closing it tightly, by means of a pump or injector, and through ββ of a valve (•), we will blow the air into the chamber. in which it does not hinder the action of the cyclist, or the placement or function of the parts or accessories of the bicycle.The internal pressure, which can be measured by means of a pressure gauge, should be such that the rigidity of the area increases considerably , without endangering the integrity of the structure In figures 4, 5 and 6, other solutions are represented, in which ducts or holes (5) that allow the passage of air, are responsible for connecting the pressures of the tubes. The second method of application described, s and represents in an example of its non-limiting execution, in figure 7. On this occasion, a frame has been modified to contain an elastic chamber that must swell inside. Both the bottom bracket (lj, as the space required seatpost (6), and the steering system (?.), Have been isolated and displaced from their normal position to allow it or lie neo id aloja¬ for said elastic chamber. The corners of the interior walls, have a rounded shape to better adapt to the elastic chamber without breaking or damaging it. It makes the inside of the frame lightly lubricated to facilitate the sliding and correct positioning of the

El aire 6 fluido gaseoso se insufla a una presión, y por unos medios igual¬ mente establecidos en el ejemplo anterior.

The valve (β), which appears outside the structure through a small hole, is placed according to the criteria established in the previous example. The gaseous fluid air 6 is blown at a pressure, and by means equally established in the previous example. A small hole (θ), may be useful in order to evacuate the air that the chamber displaces when it swells.
De todo lo anteriormente descrito, se deduce que el sis¬ tema no se limita al refuerzo de cuadros con tubos de sección circular; siendo también útil para cuadros con tubos 6 vigas huecas de sección ovalada, elíptica, discontinua Ó de cualquier otra forma, asi como a racores O uniones huecas de cualquier tipo, que compongan la estructura dpi cuadro, comprendida tam¬ bién la horquilla. Asi mismo se deduce que cualquier material de los comunmente empleados en la fabricación de cuadros, se adapta a este sistema.From all of the above, it follows that the system is not limited to the reinforcement of frames with circular section tubes; 6 hollow beams of oval, elliptical, discontinuous section OR of any other form are also useful for frames with tubes, as well as fittings or hollow joints of any type, which make up the frame dpi structure, also comprising the fork. It also follows that any material commonly used in the manufacture of frames, adapts to this system.
A las ventajas señaladas de una mayor rigidez, y resis¬ tencia local a la deformación o rotura, que pueden ser aprove¬ chadas para reducir el peso y la cantidad de material a emplear, se unen las siguientes - Las vibraciones que transmite el terreno sobre la marcha, y que se propagan por las paredes de la estructura del cuadro, se ven eliminadas o atenuadas por la presión cons¬ tante que se da sobre dichas paredes. Esto repercute posi¬ tivamente en la integridad de las uniones de los tubos y sujebcioπes de las piezas adosadas a estos. De igual modo, aporta sensaciones positivas al ciclista.To the advantages indicated of a greater rigidity, and local resistance to deformation or breakage, which can be used to reduce the weight and the amount of material to be used, the following are joined - The vibrations transmitted by the ground on the march, and that propagate through the walls of the frame structure, are eliminated or attenuated by the constant pressure that is given on said walls. This positively affects the integrity of the joints of the pipes and clamps of the pieces attached to them. Similarly, it brings positive feelings to the cyclist.
HOJA SUSTITUIDA - El sistema, en sus dos modos de aplicación, protege inte¬ riormente el cuadro, de agentes externos como la humedad, que pueden acelerar los procesos de envejecimiento del material que lo compone. - La naturaleza o composición del fluido gaseoso que se emplee, puede aportar ventajas adicionales al sistema. Por ejemplo, un gas inexplosivo e ininflamable, como el Helio, puede hacer que el peso de la estructura descien¬ da aún más, debido a su poder ascensional.SUBSTITUTED SHEET - The system, in its two application modes, internally protects the panel from external agents such as moisture, which can accelerate the aging processes of the material that composes it. - The nature or composition of the gaseous fluid used can provide additional advantages to the system. For example, an inexplosive and non-flammable gas, such as Helium, can make the structure's weight drop even more, due to its ascending power.
