Description

Object of the invention

Son bien conocidos las características y ventajas del ejercicio practicado sobre una bicicleta convencional.The characteristics are well known and advantages of exercising on a bicycle conventional.

Es un ejercicio fácil y agradable, que permite mantener las piernas y el corazón fuertes, pero que no ejercita de forma sustancial el resto de los músculos del cuerpo, en particular los de los brazos y/o de las piernas, espalda y abdomen.It is an easy and enjoyable exercise, which allows keep your legs and heart strong, but don't exercise substantially the rest of the body's muscles, in particular those of the arms and / or legs, back and abdomen.

Además la ergonomía de los sillines es bastante poco adecuada al cuerpo, produciendo molestias y dolores al cabo de un periodo de uso mas o menos
largo.In addition, the ergonomics of the saddles are not very adequate for the body, causing discomfort and pain after a period of more or less use
long.

Por tanto, se trata de realizar un vehículo que manteniendo la facilidad y el agrado ó divertimento de uso, permita ejercitar y por lo tanto fortalecer los músculos de los brazos, espalda y abdomen, evitando además los inconvenientes del uso del sillín convencional.Therefore, it is about making a vehicle that maintaining the ease and pleasure or fun of use, allow exercise and therefore strengthen the muscles of the arms, back and abdomen, also avoiding the inconvenience of using conventional saddle

Siendo su objetivo principal el ejercicio de los músculos de la parte superior del cuerpo y teniendo en consideración que el esfuerzo que producen estos es bastante inferior al de las piernas, esta invención tiene además la posibilidad de ser accionada mediante la fuerza de las piernas, siendo esto especialmente útil en terrenos con pendientes en subida pronunciadas.Its main objective being the exercise of upper body muscles and taking in consideration that the effort produced by these is quite lower than the legs, this invention also has the possibility of being operated by the strength of the legs, this being especially useful on terraced slopes pronounced.

Este vehículo se puede configurar con dos o con tres ruedas o para utilizar en aparatos de ejercicio estáticos.This vehicle can be configured with two or with three wheels or for use in static exercise equipment.

En la configuración de tres ruedas, una delantera direccional y dos traseras tractoras, presenta la ventaja de una mayor estabilidad estática y la hace especialmente indicada para personas parapléjicas.In the three-wheel configuration, one directional front and two rear tractors, has the advantage of greater static stability and makes it especially indicated for paraplegic people.

Background of the invention

Existen varias invenciones que tratan de realizar un vehículo propulsado total o al menos en parte por la fuerza de los brazos y/o de las piernas.There are several inventions that try to make a vehicle propelled totally or at least in part by the strength of the arms and / or legs.

Casi todos intentan realizar un vehículo propulsado imitando el movimiento del remo, bien con un sillín deslizante (ES2149648, WO 94/18059, EPO461286) ó impulsando con las piernas unos pedales de forma simultanea (US5280936).Almost everyone tries to make a vehicle propelled imitating the movement of the oar, well with a saddle sliding (ES2149648, WO 94/18059, EPO461286) or by driving with the Legs some pedals simultaneously (US5280936).

La direccionabilidad y la estabilidad de los aparatos con sillín deslizante, es complicada.The addressability and stability of appliances with sliding saddle, it is complicated.

El giro del manillar es en un plano distinto al de las bicicletas convencionales, siendo menos intuitivo y añadiendo otra dificultad a su posibilidad de uso.The rotation of the handlebar is in a different plane than the of conventional bicycles, being less intuitive and adding another difficulty to its possibility of use.

En todos ellos la transmisión de la fuerza se realiza mediante complejos sistemas de cadenas, proporcionando solo empuje de forma alternativa en dos de los tres inventos. Esta discontinuidad en la generación del impulso motriz disminuye el rendimiento, pudiendo llegar a pararse el vehículo desde el final un movimiento impulsor hasta el comienzo del siguiente, como pudiera ocurrir subiendo una pendiente algo pronunciada.In all of them the transmission of force is performs through complex chain systems, providing only alternately push on two of the three inventions. This discontinuity in the generation of the motor impulse decreases the performance, being able to stop the vehicle from the end a driving movement until the beginning of the next one, as I could occur by climbing a steep slope.

Existe otra invención (US5272928) que propone un vehículo de tracción por impulsos alternativos de los pies sobre unas palancas y de forma desacoplada, por impulsos alternativos de los brazos. La posibilidad de usar de forma simultanea ambas extremidades con el sistema propuesto es ficticio, ya que debido a la muy diferente fuerza que normalmente desarrollan los brazos y las piernas, los desarrollos de ambos mecanismos deberían de ser diferentes y continuamente ajustables.There is another invention (US5272928) that proposes a Alternate impulse drive vehicle of the feet on some levers and uncoupled, by alternative impulses of the arms The possibility of using both simultaneously Tips with the proposed system is fictional, because due to the very different force that arms normally develop and the legs, the developments of both mechanisms should be Different and continuously adjustable.

En cualquier caso el sistema de transmisión de la fuerza y de dirección del vehículo son totalmente distintos e inferiores en rendimiento, facilidad de uso y diseño de la realización, a los propuestos en mi invención.In any case the transmission system of the strength and direction of the vehicle are totally different and inferior in performance, ease of use and design of the embodiment, to those proposed in my invention.

Description of the invention

Se trata de un vehículo biciclo o triciclo propulsado con la fuerza ejercida por los brazos, sobre una palanca que mediante unos tirantes o bielas mueven la rueda o ruedas traseras produciendo una propulsión continuada, ejercida en los dos sentidos del movimiento de la palanca y que está dirigido mediante un manillar que acciona la rueda delantera.It is a bicycle or tricycle vehicle propelled with the force exerted by the arms, on a lever that by means of braces or connecting rods move the wheel or wheels rear producing continuous propulsion, exerted on both senses of lever movement and that is directed by a handlebar that drives the front wheel.

Esta misma palanca tiene la posibilidad de ser accionada por las piernas, mediante un cable o por tirantes rígidos fijados a esta palanca por un extremo y al reposapiés por el otro. Este sistema es desconectable a voluntad, pudiéndose utilizar en los tramos mas duros o para alcanzar mayor velocidad.This same lever has the possibility of being operated by the legs, by a cable or by rigid braces fixed to this lever at one end and the footrest at the other. This system is disconnectable at will, and can be used in the hardest sections or to reach greater speed.

Además tiene un sistema de freno de bicicletas convencionales, así como la posibilidad de instalar un sistema de cambio de marchas de bicicletas convencionales.It also has a bicycle brake system conventional, as well as the possibility of installing a system of Conversion of conventional bicycle gears.

El sistema de propulsión se basa en el movimiento de vaivén longitudinal, hacía adelante y hacía atrás, de una palanca vertical articulada en el chasis y de la que articulan a sus dos lados sendas bielas o palancas.The propulsion system is based on the longitudinal reciprocating movement, forward and backward, of a vertical lever articulated in the chassis and from which they articulate a Its two sides are connecting rods or levers.

Cada uno de estos bielas acciona un cojinete unidireccional, situados y fijados en un mismo eje.Each of these connecting rods drives a bearing unidirectional, located and fixed on the same axis.

Por cojinete unidireccional quiero significar cualquiera sistema de los que permiten el giro libre de una de las partes del mismo sobre la que esta solidaria al eje o al eje mismo, en un sentido de giro y sea solidario sobre la que esta solidaria al eje o al eje mismo, en el otro sentido de giro, mediante un sistema de tipo trinquete, como por ejemplo los piñones convencionales de bicicleta, o cualquier otro sistema, acuñamiento de bolas o cilindros entre las dos parte etc..By unidirectional bearing I mean any system that allows free rotation of one of the parts of it on which it is attached to the axis or to the axis itself, in a sense of rotation and be supportive about which you are in solidarity to the axis or to the axis itself, in the other direction of rotation, by means of a ratchet type system, such as pinions conventional bicycle, or any other system, coining of balls or cylinders between the two parts etc.

Dichos cojinetes tienen un enganche o pivote para fijar de forma articulada cada uno el correspondiente extremo de su biela.These bearings have a hitch or pivot to articulate each one of them the corresponding end of his crank.

Una de las bielas ataca al cojinete por su parte superior y la otra al otro por la inferior, de esta forma al accionar la palanca en su movimiento de vaivén, se obtiene un movimiento circular continuo en el eje de los cojinetes.One of the connecting rods attacks the bearing on its part superior and the other to the other by the inferior, in this way to actuate the lever in its reciprocating motion, you get a Continuous circular motion in the bearing shaft.

Solidario a este eje se sitúa una polea o engranaje, que permite transmitir el movimiento a la rueda o ruedas.Solidarity to this axis is a pulley or gear, which allows the movement to be transmitted to the wheel or wheels.

Cuando la palanca es accionada por las piernas, el funcionamiento general es el mismo, la fuerza se transmite a la palanca mediante el cable o los tirantes accionados por las mismas y se añade a la proporcionada por los brazos. Cuando no se usa esté sistema se desconecta el cable y se bloquea el reposapiés para un mayor control del vehículo.When the lever is operated by the legs, the general operation is the same, the force is transmitted to the lever by means of the cable or the braces actuated by them and It is added to the one provided by the arms. When not in use, be system disconnects the cable and the footrest is locked for a Greater control of the vehicle.

Articulado al extremo superior de la palanca, se sitúa un manillar, que además de tener unas empuñaduras adecuadas para ejercer el movimiento de vaivén, permite accionar el sistema de dirección de forma similar al de las bicicletas convencionales.Articulated to the upper end of the lever, it place a handlebar, which in addition to having suitable handles to exercise the reciprocating movement, it allows to activate the system of address similar to conventional bicycles.

Este sistema tiene la particularidad de que la distancia entre el manillar y la rueda, debido al movimiento de vaivén, es variable.This system has the peculiarity that the distance between the handlebars and the wheel, due to the movement of reciprocating, it is variable.

Consta, por tanto, de unos cables accionados por el manillar y fijados a cada lado del eje de giro del mismo y que transforman el movimiento circular de este, en un desplazamiento de los cables dentro de unas camisas flexibles. Estas camisas flexibles tienen uno de sus extremos alojados en una pieza fija a la palanca vertical y el otro en una pieza fija al chasis del vehículo.It consists, therefore, of cables powered by the handlebar and fixed to each side of the axis of rotation of the same and that they transform the circular movement of this into a displacement of the cables inside flexible shirts. These shirts flexible have one of its ends housed in a piece fixed to the vertical lever and the other in a piece fixed to the chassis of the vehicle.

El otro extremo de los cables se fija a una pieza solidaria con la horquilla de la rueda direccional, transformando de nuevo el movimiento longitudinal en circular, produciendo el correspondiente giro de la rueda.The other end of the cables is fixed to a solidarity piece with the fork of the steering wheel, transforming the longitudinal movement into circular again, producing the corresponding wheel rotation.

El reposapiés desliza por su tubo soporte mediante las muescas adecuadas.The footrest slides through its support tube by the appropriate notches.

Debido a la forma de erogación, el usuario irá sentado en un asiento con respaldo y los pies apoyados en una barra transversal al vehículo o reposapiés. Estos dos puntos de apoyo permiten a los brazos realizar la fuerza necesaria para la propulsión.Due to the form of dispensation, the user will go sitting in a seat with backrest and feet resting on a bar transverse to the vehicle or footrest. These two points of support allow the arms to perform the necessary force for the propulsion.

Description of a preferred embodiment

Sin que tengan carácter limitativo, se expone a continuación un modo concreto de realización de la presente invención.Without being limiting, it is exposed to below a specific embodiment of the present invention.

Se trata de un vehículo de dos ruedas, con su chasis correspondiente (1) que soporta un asiento (2) con su respaldo (3) y un soporte para apoyar los pies (4 y 5).It is a two-wheeled vehicle, with its corresponding chassis (1) that supports a seat (2) with its backrest (3) and a support to support the feet (4 and 5).

Sujeto a este chasis mediante una articulación (6), hay una palanca en forma de horquilla (7) que soporta el manillar (8a) y dos palancas (10a y 10b).Subject to this chassis through a joint (6), there is a fork-shaped lever (7) that supports the handlebar (8a) and two levers (10a and 10b).

La articulación (6) permite un movimiento de vaivén de la palanca (7) en sentido longitudinal al vehículo.The joint (6) allows a movement of swing of the lever (7) longitudinally to the vehicle.

Las dos palancas (10a y 10b), están articuladas en (11a y 11b) una a cada lado de la horquilla (7) y accionan sendos piñones o cojinetes de un único sentido de giro (12a y 12b), que son atacados por las palancas (10a y 10b) mediante las articulaciones (13a y 13b).The two levers (10a and 10b), are articulated in (11a and 11b) one on each side of the fork (7) and actuate single sprockets or bearings with a single direction of rotation (12a and 12b), that are attacked by the levers (10a and 10b) by joints (13a and 13b).

Estos piñones (12a y 12b) están situados a ambos lados del cigüeñal (14) del vehículo y son solidarios a él, y al ser accionados en su sentido de trabajo, alternativamente por las palancas (10a y 10b), transmiten el movimiento de vaivén de la horquilla (7) al cigüeñal, proporcionando un giro continuo al mismo, que produce el avance del vehículo mediante un sistema convencional de plato (15) (solidario al cigüeñal (14)), cadena (16) y piñones (17).These pinions (12a and 12b) are located at both sides of the crankshaft (14) of the vehicle and are integral to it, and to the be driven in their sense of work, alternatively by levers (10a and 10b), transmit the reciprocating movement of the fork (7) to the crankshaft, providing a continuous rotation to it, which produces the advance of the vehicle through a conventional system of plate (15) (crankshaft joint (14)), chain (16) and pinions (17).

En el movimiento de avance de la horquilla (7), la palanca (10a) acciona el piñón (12a), que es atacado por el extremo (13a) en su sentido de trabajo, produciendo un giro a derechas de menos de 180 grados, mientras que la palanca (10b) del otro lado efectúa un movimiento de retroceso en vacío de su piñón (12b) correspondiente.In the forward movement of the fork (7), the lever (10a) drives the pinion (12a), which is attacked by the extreme (13a) in its sense of work, producing a turn to rights of less than 180 degrees, while the lever (10b) of the on the other hand it performs a backward movement of its pinion (12b) corresponding.

En el movimiento de retroceso de la horquilla (7), la palanca (10b) acciona el piñón (12b), que es atacado por el extremo (13b) en su sentido de trabajo, produciendo un giro a derechas de menos de 180 grados, mientras que la palanca (10a) del otro lado efectúa un movimiento de retroceso en vacío de su piñón (12a) correspondiente.In the reverse movement of the fork (7), the lever (10b) drives the pinion (12b), which is attacked by the extreme (13b) in its sense of work, producing a turn to rights of less than 180 degrees, while the lever (10a) of the on the other hand it performs a backward movement of its pinion (12a) corresponding.

La palanca (10a) que ataca al cojinete por la parte superior lleva un muelle (30) cuyo otro extremo va fijado al chasis. El objetivo de este muelle es evitar que la palanca caiga por efecto de la fuerza de gravedad.The lever (10a) that attacks the bearing by the upper part has a spring (30) whose other end is fixed to the chassis. The objective of this spring is to prevent the lever from falling due to the effect of the force of gravity.

Cuando la horquilla (7) es accionada también por las piernas, el funcionamiento general es el mismo, la fuerza se transmite a la horquilla (7) mediante el cable (25) fijado a la horquilla (7) en la fijación (26) y al reposapiés (5) mediante la fijación (27). El reposapiés desliza por la acanaladura (28) de la pieza (4). Dicha acanaladura está protegida por una pieza de teflón o material similar que facilita el deslizamiento.When the fork (7) is also driven by the legs, the general functioning is the same, the strength is transmitted to the fork (7) by means of the cable (25) fixed to the fork (7) in the fixing (26) and the footrest (5) by means of the fixing (27). The footrest slides along the groove (28) of the piece (4). This groove is protected by a piece of Teflon or similar material that facilitates sliding.

Para desconectar este sistema se soltará el cable (25) de su fijación en (26), sacando el eje pasante que atraviesa la fijación (26) y soltando el extremo del cable. También se fijará el reposapiés a la pieza (4) para un mejor control del vehículo.To disconnect this system, the cable (25) of its fixation in (26), taking out the through shaft that through the fixing (26) and releasing the end of the cable. Too the footrest will be fixed to the piece (4) for better control of the vehicle.

Otra posible sistema de accionamiento de la palanca (7) por las piernas es el de la Figura 4, aquí el reposapiés es solidario a una pieza perpendicular (31) que está articulada a la pieza (32).Another possible drive system of the lever (7) by the legs is that of Figure 4, here the footrest is integral to a perpendicular piece (31) that is articulated to the piece (32).

Se selecciona el cable flexible en lugar de las palancas rígidas porque el cable es mas sencillo de escamotear cuando no se esta usando este sistema.The flexible cable is selected instead of the rigid levers because the cable is easier to skip when this system is not being used.

El movimiento de retroceso del reposapiés (5) se producirá con el movimiento de retroceso de la horquilla (7).The kickback movement of the footrest (5) is will produce with the reverse movement of the fork (7).

El sistema de dirección consta de un manillar (8a) con un eje perpendicular a él (8b), que se articula en el extremo superior de la horquilla (7), permitiendo el giro del manillar.The steering system consists of a handlebar (8a) with an axis perpendicular to it (8b), which is articulated in the upper end of the fork (7), allowing the rotation of the handlebar.

El eje (8b) puede ser fijado a una altura variable dentro de la horquilla (7), lográndose una variación del brazo del brazo de palanca.The shaft (8b) can be fixed at a height variable inside the fork (7), achieving a variation of the lever arm arm.

Acoplados al manillar (8a) hay unas asas perpendiculares (9a y 9b), que permiten una mas cómoda posición de trabajo de las manos.Attached to the handlebar (8a) there are some handles perpendicular (9a and 9b), which allow a more comfortable position of hand work.
