Description

Bicicleta multitalla.Multi-size bike

El sector de la técnica de esta invención es el de las bicicletas, y particularmente de las que actualmente se dotan de diversas relaciones de dientes en platos y piñones.The technical sector of this invention is the of bicycles, and particularly those currently they endow with diverse relations of teeth in plates and pine nuts.

Indicación del Estado de la Técnica anterior. Es conocida la bicicleta "plegable" ES308029P, consistente en un cuerpo o chasis que dispone una bisagra con un pasador que permite la articulación del chasis por ese punto de modo que reduce su tamaño a efectos de transporte y almacenamiento en viviendas o vehículos. Estas bicicletas disponen una regulación de talla consistente en la posibilidad de alargar el cuerpo soporte del sillín, de modo que el tubo que lo sustenta pueda adoptar distintas alturas. El manillar, por su parte, también puede adaptarse de modo que disponiendo forma de "V", puede inclinarse adelante o atrás, y elevarse, de modo también que permita la adaptación a la medida de los brazos del usuario. Sin embargo, la altura de la bicicleta en estos casos permanece, así como la medida de las ruedas.Indication of the prior art. Is known the "folding" bike ES308029P, consisting of a body or chassis that has a hinge with a pin that allows the articulation of the chassis at that point so that it reduces its size for the purpose of transport and storage in homes or vehicles. These bicycles have a size regulation consisting of the possibility of lengthening the support body of the saddle, so that the tube that supports it can adopt different heights The handlebar, on the other hand, can also be adapted so that having a "V" shape, you can lean forward or back, and rise, so as to allow adaptation to the measure of the user's arms. However, the height of the bike in these cases remains, as well as the extent of wheels.

También la ES 486163 por "bicicleta reducible", se estructura como un vehículo de dos ruedas que dispone un cuadro formado por dos partes acoplables entre sí mediante un mecanismo por el que la parte anterior dispone un tubo enlazable con la posterior, que puede ajustarse en longitud. Las ruedas permanecen invariables sea cual sea la elongación que se lleve a cabo, y no permite variar sino la longitud, no la talla de la bicicleta.Also the ES 486163 for "bicycle reducible ", is structured as a two-wheeled vehicle that It has a frame formed by two parts that can be coupled together by means of a mechanism whereby the front part has a tube linkable with the back, which can be adjusted in length. The wheels remain unchanged regardless of the elongation carry out, and does not allow to vary but the length, not the size of the bike.

No es desconocido que los principales usuarios de las bicicletas como primer medio de transporte, son los niños, que desde que aprenden en un vehículo infantil, van necesitando distintas tallas de bicicleta de modo que entre sus 7 y 12 años necesitan al menos dos o tres bicicletas distintas por el rápido crecimiento de los niños a esas edades.It is not unknown that the main users of bicycles as the first means of transport, are children, that since they learn in a children's vehicle, they need different bike sizes so that between 7 and 12 years old they need at least two or three different bicycles for the quick Children's growth at those ages.

Por otra parte, y como observación general, el tamaño de la rueda condiciona la seguridad de la bicicleta; la rueda grande facilita que los baches queden mejor absorbidos que en el caso de que la rueda sea pequeña, especialmente cuando el peso del usuario es considerable. Esto además de que la sensación del aumento de tamaño con la edad produce una especial satisfacción cuando también se dispone de una bicicleta con rueda de tamaño superior.On the other hand, and as a general observation, the Wheel size conditions the safety of the bicycle; the large wheel makes potholes better absorbed than in the case that the wheel is small, especially when the weight of the user is considerable. This in addition to the feeling of increase in size with age produces a special satisfaction when a bicycle with a wheel size is also available higher.

No se conocen hasta el momento presente, bicicletas que puedan adaptar su medida a la de distintos formatos de rueda, y que puedan además modificar su talla adaptándose a la de la rueda.They don't know each other until now, bicycles that can adapt their size to different formats of wheel, and that they can also modify their size adapting to the of the wheel.

La presente invención tiene por objeto una bicicleta multitalla, que permite instalar distintos diámetros de rueda y distintos ajustes de tamaño de chasis, de modo que un mismo chasis se adapta con una mínima adaptación a un tamaño mayor, permitiendo la instalación de ruedas de mayor diámetro a las que también queda adaptado el sistema de frenos.The present invention aims at a multi-bike, which allows to install different diameters of wheel and different chassis size settings, so that the same chassis adapts with minimal adaptation to a larger size, allowing the installation of larger diameter wheels to which the brake system is also adapted.

Explanation of the invention.

La presente bicicleta tiene un chasis dividido en dos partes. Una primera, sustenta el sillín, en cuya base dispone los pedales. Cruza esta estructura una pieza curvada que por una parte desciende hasta constituir el eje de la rueda trasera, y se alza terminando en una pieza macho. A esta pieza macho se le inserta la parte anterior de la bicicleta. Esta parte anterior sustenta el manillar y con éste la horquilla delantera. La parte anterior permite que sea insertada a diversas profundidades en el macho, de modo que la longitud entre manillar y sillín se varía de este modo.This bike has a split chassis in two parts. A first, supports the saddle, at whose base arrange the pedals. A curved piece crosses this structure that on the one hand it descends until it constitutes the axis of the wheel rear, and rises ending in a male piece. To this piece male the front part of the bicycle is inserted. This part previous supports the handlebar and with it the front fork. The anterior part allows it to be inserted at various depths in the male, so that the length between handlebars and saddles is It varies in this way.

La horquilla delantera dispone unos distintos puntos de fijación de los frenos. Como es sabido, los frenos delanteros de una bicicleta se hallan unidos a la horquilla. Si se varía el tamaño de la rueda, las zapatas de los frenos no coinciden con la llanta sobre la que deben actuar. Por ello se ha previsto además de las correderas comunes para ajuste de los frenos de todas las bicicletas, un conjunto de varios orificios de fijación, de modo que extrayendo la fijación de una posición, puede fijarse nuevamente en una posición adaptada a la nueva rueda.The front fork has different fixing points of the brakes. As is known, the brakes Front of a bicycle are attached to the fork. Whether wheel size varies, brake shoes do not match with the tire on which they must act. That is why it is planned in addition to the common sliders for adjusting the brakes of all bicycles, a set of several fixing holes, of so that by removing the fixation of a position, it can be fixed again in a position adapted to the new wheel.

La horquilla posterior, está formada por un doble cuerpo, interno y exterior, de modo que produce un refuerzo y una rigidez estructural suficiente. Su extremo aloja el eje de la rueda y sustenta el desviador de piñones. La parte alta posee también un dispositivo de regulación de la posición donde se disponen los frenos, con idéntico efecto que el comentado con respecto a la horquilla delantera.The rear fork, is formed by a double body, internal and external, so that it produces a reinforcement and sufficient structural rigidity. Its end houses the axis of the wheel and support the pinion derailleur. The upper part has also a position regulation device where they have the brakes, with the same effect as the one commented with with respect to the front fork.

La estructura del chasis que desciende hasta el eje de pedales dispone también la fijación para el mecanismo desviador selector de platos. Este cuerpo puede también estar formado en dos partes macho y hembra, de modo en una realización posible, pueda alargarse para distanciar el sillín de los pedales sin que la disposición de una rueda grande suponga la elevación excesiva de los pedales con respecto al suelo.The chassis structure that descends to the pedal axle also has the fixation for the mechanism plate selector diverter. This body can also be formed in two male and female parts, so in one embodiment possible, it can be extended to distance the saddle from the pedals without the arrangement of a large wheel assuming elevation excessive pedals with respect to the ground.

La bicicleta, tal y como se ha explicado, puede dotarse de suspensión manteniendo sus características mediante la adición en el eje delantero, y también trasero, de un mecanismo elástico, telescópico o basculante, que absorba las irregularidades del firme. En este caso, se dota a la bicicleta de freno de tambor o de disco, de modo que hace independiente el tamaño de la rueda y su eventual movimiento a lo largo de las horquillas con la posibilidad de que disponga de un medio de frenado eficaz.The bicycle, as explained, can provide suspension while maintaining its characteristics through addition on the front and also rear axle of a mechanism elastic, telescopic or tilting, which absorbs irregularities of the firm. In this case, the drum brake bicycle is provided or disk, so that it makes the wheel size independent and its eventual movement along the forks with the possibility of having an effective braking means.

Explicadas las características elementales básicas de la bicicleta, pasamos a dar explicación de un modo de realización.Explained the elementary characteristics basic of the bicycle, we will give an explanation of a way of realization.

Como se aprecia en la figura 3 que muestra un despiece del chasis de la bicicleta, la estructura del chasis comprende dos partes. Un chasis externo, que es la estructura base del cuadro, y un refuerzo interno constituido por la parte interior 23 de la horquilla 23 que dispone una prolongación anterior que abraza con el soporte 24 para el tubo 38, el tubo que constituye la hembra donde se inserta el tubo del sillín. Este refuerzo interno dispone unas aletas 39 que son coincidentes con las aletas 22 de la parte externa 1 y favorecen la rigidez estructural. En dicho refuerzo interno se disponen también unos alojamientos 27 para las piezas de soporte 26 del freno posterior, de modo que coadyuvan a la rigidez del conjunto. El tubo 38, tiene un extremo inferior 25 que acoge los rodamientos del eje del pedalier que se señala en la parte externa con 3. Externamente la estructura base del cuadro 1 posee una forma dividida longitudinalmente en dos mitades que se insertan y fijan entre sí, y que se corresponden superponiéndose a la estructura de refuerzo interno 23. Estas dos mitades, simétricas, acogen además la fijación 31 del desviador de platos 19, y su porción anterior posee un estrechamiento que forma un macho 33 susceptible de insertarse a distintas profundidades en la estructura anterior del cuadro 7, según las distintas regulaciones con identificador de talla 34. La porción extrema macho puede variar de longitud hasta ocupar incluso la totalidad de la parte 7 en aras de asegurar la rigidez de la inserción.As seen in Figure 3 which shows a Exploded view of the bicycle chassis, the chassis structure It comprises two parts. An external chassis, which is the base structure of the frame, and an internal reinforcement constituted by the inner part 23 of the fork 23 which has an anterior extension which hugs with the support 24 for the tube 38, the tube that constitutes the female where the saddle tube is inserted. This internal reinforcement it has fins 39 that are coincident with fins 22 of the external part 1 and favor structural rigidity. In said internal reinforcement there are also some 27 housings for support parts 26 of the rear brake, so that they contribute to the set stiffness. The tube 38 has a lower end 25 which welcomes the bottom bracket shaft bearings indicated on the part external with 3. Externally the base structure of table 1 has a form divided longitudinally into two halves that are inserted and fix each other, and that correspond overlapping the internal reinforcement structure 23. These two halves, symmetrical, they also include fixing 31 of the plate diverter 19, and its anterior portion has a narrowing that forms a male 33 liable to be inserted at different depths in the previous structure of table 7, according to the different regulations with size identifier 34. The male end portion can vary in length until it occupies even the entire part 7 in order to ensure the rigidity of the insertion.

La fijación entre las partes 1 y 7 tiene lugar mediante el dispositivo de fijación 12 que puede estar formado por una pieza independiente, o disponerse en el extremo de la pieza 7 y unido a esta parte.The fixing between parts 1 and 7 takes place by means of the fixing device 12 which can be formed by an independent piece, or arranged at the end of part 7 and attached to this part.

Es posible que la unión entre el chasis 1 y la parte anterior 7 tenga una doble fijación, ya que además de la fijación 12 situada en el exterior, que oprime la parte exterior de la fijación con respecto a la interior, en el tramo extremo de la inserción puede disponer un dispositivo de expansión mediante el que se afirma e inmoviliza esta parte extrema interior con respecto a la externa. De este modo evita el eventual campaneo que la tolerancia que permite la inserción de una pieza con otra pudiera producir, especialmente si se produce desgaste en la zona de contacto de ambas partes.It is possible that the joint between chassis 1 and the previous part 7 has a double fixation, since in addition to the fixation 12 located on the outside, which presses the outer part of the fixation with respect to the interior, in the extreme section of the insertion can arrange an expansion device using the that this extreme inner part is affirmed and immobilized with respect to the external This avoids the eventual campaign that the tolerance that allows the insertion of a piece with another could produce, especially if wear occurs in the area of contact of both parties.

Es posible proporcionar a la bicicleta resultante una mayor rigidez estructural a base de vincular los extremos entre sí. De este modo, teniendo el chasis forma de "T" cuya parte superior se inclina hasta alcanzar el eje trasero de la rueda, se dispone un tirante 29 entre el eje del pedalier y el eje trasero de la rueda. También se dispone un tirante 32 dotado de regulación longitudinal 37, entre la parte inferior extrema de la estructura 7 y el eje del pedalier 3, que en su extremo vinculado a dicho eje 3, dispone una forma a modo de estribo 41, simétrica que une ambas partes del eje 3.It is possible to provide the bicycle resulting in greater structural rigidity based on linking the ends with each other. Thus, having the chassis in the form of "T" whose upper part tilts until it reaches the axis rear of the wheel, a brace 29 is arranged between the axle of the bottom bracket and rear wheel axle. There is also a strap 32 provided with longitudinal adjustment 37, between the part extreme bottom of the structure 7 and the bottom bracket 3, which in its end linked to said axis 3, has a form by way of stirrup 41, symmetrical that joins both parts of axis 3.

La parte interior de la estructura base 1 posee unas bridas 28 que posibilitan la fijación intermedia del tubo de inserción del tubo 13 del sillín, y así su estabilización de modo que impide vibraciones o movimientos de flexión.The inner part of the base structure 1 has flanges 28 that allow intermediate fixation of the tube insertion of the seat tube 13, and thus its stabilization so which prevents vibrations or bending movements.

La estructura base del cuadro posee un paso 36 para los cables de los cambios de plato, para los cambios de piñón y para el freno posterior. También posee un casquillo 42 unido a una base de casquillo 43 susceptible de ser insertada en el orificio 44 de la estructura 7 de modo que la unión de la estructura 1 con respecto a la 7 se estabilicen por su unión perimetral así como por la unión central, evitando vibraciones o movimientos indeseados que afecten a la rigidez de la unión.The base structure of the frame has a step 36 for plate change cables, for pinion changes and for the rear brake. It also has a socket 42 attached to a socket base 43 capable of being inserted in the hole 44 of structure 7 so that the union of the structure 1 with respect to 7 stabilize by joining perimeter as well as by the central union, avoiding vibrations or unwanted movements that affect the stiffness of the joint.
