La presente invention se encuadra en el campo tecnico de los accesorios para sillas de ruedas, asl como en el de los aparatos para lanzamiento de pelotas, y se refiere en particular a un dispositivo mecanico para impulsar un balon simulando tiros horizontales o parabolicos, acoplable en sillas de ruedas para permitir la practica del futbol a personas con movilidad reducida.The present invention falls within the technical field of wheelchair accessories, as well as that of ball launching devices, and refers in particular to a mechanical device for driving a ball simulating horizontal or parabolic shots, attachable in wheelchairs to allow people with reduced mobility to practice soccer.

ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION

Los deportes parallmpicos, es decir, aquellos adaptados para personas con diferentes discapacidades, abarcan un numero cada vez mayor de disciplinas, y entre ellas se encuentra uno de los deportes mas practicados y seguidos en todo el mundo, como es el futbol.Paralympic sports, that is, those adapted for people with different disabilities, cover an increasing number of disciplines, and among them is one of the most practiced and followed sports worldwide, such as football.

El futbol en silla motorizada cuenta con una gran popularidad e incluso tiene su propia federation, conocida como Federacion Internacional de Asociaciones de Futbol en silla electrica (FIPFA, por sus siglas en ingles). Este deporte se practica en canchas de baloncesto de tamano estandar, entre dos equipos con 5 jugadores cada uno. Segun las reglas de la citada FIPFA, los jugadores estan obligados a utilizar una silla electrica con 4 o mas ruedas, y la velocidad maxima permitida durante un partido es de 10 km/h Los jugadores deben llevar un cinturon de seguridad y proteccion para los pies, y la pelota utilizada es similar a un balon de futbol pero con mayor tamano, con un diametro de 33 cm.Motorized chair soccer has great popularity and even has its own federation, known as the International Federation of Electric Chair Soccer Associations (FIPFA). This sport is practiced in basketball courts of standard size, between two teams with 5 players each. According to the rules of the aforementioned FIPFA, players are required to use an electric chair with 4 or more wheels, and the maximum speed allowed during a match is 10 km / h Players must wear a safety belt and foot protection , and the ball used is similar to a soccer ball but with a larger size, with a diameter of 33 cm.

En el actual estado de la tecnica se conocen dispositivos acoplables a sillas de ruedas para simular tiros de una pelota realizados con el pie, aunque no contemplan la posibilidad de realizar distintos tipos de disparos (recto como en un chut directo, parabolico simulando una volea, etc.).In the current state of the art, devices that can be attached to wheelchairs are known to simulate shots of a ball made with the foot, although they do not contemplate the possibility of making different types of shots (straight as in a direct kick, parabolic simulating a volley, etc.).

DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION

El dispositivo impulsor de balon, acoplable en todo tipo de sillas de ruedas, permite la practica del futbol a personas discapacitadas con un mayor nivel de precision, al poder controlarse el tipo de tiro que se realiza, pudiendo ser este horizontal o parabolico. En una realization preferente, el dispositivo comprende una pareja de mecanismos independientes y simetricos entre si respecto a un plano longitudinal pasante por el centro de la silla de ruedas. Los mecanismos de este dispositivo se unen sobre una base acoplable a la parte inferior de la cara frontal de la silla.The ball-driving device, attachable in all types of wheelchairs, allows the practice of soccer to disabled people with a higher level of precision, being able to control the type of shot that is made, being able to be this horizontal or parabolic. In a preferred embodiment, the device comprises a pair of independent and symmetrical mechanisms with respect to a longitudinal plane passing through the center of the wheelchair. The mechanisms of this device are attached on a base that can be attached to the lower part of the front face of the chair.

Cada uno de los mecanismos constituyentes del dispositivo comprende una palanca de accionamiento manual desplazable en un selector de position, para determinar el tipo de tiro que se desea realizar. Dicha palanca comprime o expande, mediante un mecanismo de transmision del movimiento, un elemento elastico, que preferentemente es un muelle o resorte. La contraction o expansion de dicho elemento elastico produce el desplazamiento en un sentido u otro de un elemento impulsor al cual se encuentra vinculado.Each of the constituent mechanisms of the device comprises a manually operated lever that can be moved in a position selector to determine the type of shot to be made. Said lever compresses or expands, by means of a movement transmission mechanism, an elastic element, which is preferably a spring or spring. The contraction or expansion of said elastic element causes the displacement in one direction or another of a driving element to which it is linked.

El elemento impulsor tiene solidariamente vinculado a su vez un soporte de empuje para impulsar el balon, cuyo movimiento esta por tanto determinado por el del elemento impulsor, que a su vez esta gobernado por el posicionamiento de la palanca en el selector de posicion.The driving element has in turn linked to a thrust support to drive the ball, whose movement is therefore determined by that of the driving element, which in turn is governed by the positioning of the lever in the position selector.

El mecanismo comprende adicionalmente un sistema capaz de transformar la direction del movimiento de rectillnea a curva. Para ello, un rodillo vinculado al elemento impulsor se desplaza en el interior de una gula que cuenta con un tramo rectillneo y un tramo curvado, en el que dicho tramo curvado cuenta a su vez con un sector descendente y un sector ascendente, y en el que elThe mechanism additionally comprises a system capable of transforming the direction of the movement from rectilinear to curved. To do this, a roller linked to the driving element travels inside a glutton that has a straight section and a curved section, in which said curved section has in turn a descending sector and an ascending sector, and in the that he

tramo rectillneo esta conectado por sus extremos a los extremos del tramo curvado. El posicionamiento de dicho rodillo en un tramo u otro de la gula esta determinado por la posicion de la palanca de accionamiento en el selector de posicion.straight section is connected by its ends to the ends of the curved section. The positioning of said roller in one section or another of the glutton is determined by the position of the operating lever in the position selector.

Partiendo de una posicion inicial, en la cual la palanca de accionamiento esta en situation de reposo y el elemento elastico, en este caso el resorte, se encuentra expandido, el desplazamiento de dicha palanca hacia la posicion de tiro horizontal o de tiro parabolico pone en comprime dicho resorte acumulandose energla mecanica y pone en funcionamiento el mecanismo.Starting from an initial position, in which the actuation lever is at rest and the elastic element, in this case the spring, is expanded, the displacement of said lever towards the horizontal or parabolic shot position puts It compresses said spring by accumulating mechanical energy and activates the mechanism.

Cuando el usuario desacopla la palanca de la posicion de tiro horizontal o parabolico en el selector de posicion, preferentemente mediante giro de dicha palanca, el mecanismo de transmision libera el resorte del elemento elastico, que recupera instantaneamente su posicion de reposo. En consecuencia, la energla acumulada se libera en forma de movimiento rectillneo al elemento impulsor, que segun el posicionamiento del rodillo en la gula, determinado por la posicion inicial de la palanca de accionamiento en el selector de posicion, mantiene ese movimiento para obtener un tiro rectillneo o lo transforma para efectuar un tiro parabolico.When the user disengages the lever from the horizontal or parabolic shot position in the position selector, preferably by turning said lever, the transmission mechanism releases the spring from the elastic element, which instantly recovers its resting position. Consequently, the accumulated energy is released in the form of a rectilinear movement to the driving element, which according to the positioning of the roller in the glutton, determined by the initial position of the operating lever in the position selector, maintains that movement to obtain a shot. rectilinear or transform it to make a parabolic shot.

De esa manera, en el caso en que la palanca este situada en la posicion de tiro horizontal, el rodillo del elemento impulsor se desplaza en el tramo rectillneo de la gula, por lo que dicho elemento impulsor se mueve mediante un movimiento rectillneo, desplazando a su vez al elemento impulsor, que golpea al balon mediante un impulso rectillneo de manera que se obtiene un tiro horizontal.Thus, in the case where the lever is located in the horizontal shooting position, the roller of the impeller element moves in the rectilinear section of the glutton, whereby said impeller element is moved by a rectilinear movement, displacing in turn to the driving element, which hits the ball by a rectilinear impulse so that a horizontal shot is obtained.

Cuando la palanca se encuentra situada en la posicion de tiro parabolico en el selector de posicion, el rodillo se desplaza en el tramo curvo de la gula. El recorrido por el sector descendente de dicho tramo determina un movimiento descendente del elemento impulsor, y por tanto del soporte de empuje, que rodea la superficie inferior del balon, mientras que el recorrido por el tramo ascendente provoca el impulso hacia arriba del balon contenido por el soporte de empuje, de manera que de la combination de ambos movimientos se obtiene un tiro paralelo.When the lever is located in the parabolic pull position in the position selector, the roller moves in the curved section of the glutton. The route along the descending sector of said section determines a downward movement of the driving element, and therefore of the thrust support, which surrounds the lower surface of the ball, while the route along the ascending section causes the upward thrust of the ball contained by the push support, so that a parallel shot is obtained from the combination of both movements.

El dispositivo as! descrito se acopla a una silla de ruedas, preferentemente del tipo de aquellas especlficamente disenadas para la practica deportiva, sin aportar un sobrepeso tal que comprometa su ligereza, y supone un mecanismo sencillo y facilmente manejable que permite realizar unos disparos mas precisos y variados, mejorando la experiencia del usuario en la practica deportiva.The device as! described is coupled to a wheelchair, preferably of the type of those specifically designed for sports, without providing an overweight such that compromises its lightness, and is a simple and easily manageable mechanism that allows more precise and varied shots, improving User experience in sports practice.

REALIZACION PREFERENTE DE LA INVENCIONPREFERRED EMBODIMENT OF THE INVENTION

Seguidamente se proporciona, con ayuda de las figuras anteriormente referidas, una explication detallada de un ejemplo de realization preferente del objeto de la presente invention.Next, a detailed explanation of an example of preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.

El dispositivo impulsor de balon para silla de ruedas que se describe comprende al menos un mecanismo (1), del que se muestra una vista lateral de un corte longitudinal en la figura 3 en su posicion de reposo. Dicho mecanismo (1) comprende a su vez una palanca de accionamiento (2), manejada manualmente por el usuario, cuyo movimiento es transmitido, a traves de un mecanismo de transmision (3), a un elemento elastico (4) al cual se encuentra vinculado. Dicho elemento elastico (4) tiene la capacidad de comprimirse o expandirse en funcion del movimiento ejercido por el usuario sobre la palanca (2), y se encuentra vinculado a un elemento impulsor (5).The wheelchair driving device described above comprises at least one mechanism (1), of which a side view of a longitudinal section is shown in Figure 3 in its resting position. Said mechanism (1) in turn comprises a drive lever (2), manually operated by the user, whose movement is transmitted, through a transmission mechanism (3), to an elastic element (4) to which it is located linked. Said elastic element (4) has the ability to compress or expand depending on the movement exerted by the user on the lever (2), and is linked to a driving element (5).

En la realizacion preferente mostrada en las figuras 1 a 8, el mecanismo de transmision (3) comprende un cable que conecta la palanca de accionamiento (2) con el elemento elastico (4), con unas poleas (6) adicionales situadas a distintas alturas y en torno a las cuales desliza el cable, mientras que el elemento elastico (4) comprende un mecanismo tipo piston, con un resorte (7) desplazable en el interior de un cilindro (8), y el elemento impulsor (5) comprende un eje articulado.In the preferred embodiment shown in Figures 1 to 8, the transmission mechanism (3) comprises a cable that connects the operating lever (2) with the elastic element (4), with additional pulleys (6) located at different heights and around which the cable slides, while the elastic element (4) comprises a piston-like mechanism, with a spring (7) movable inside a cylinder (8), and the driving element (5) comprises a articulated shaft

Dicho elemento impulsor (5) se desplaza en funcion de los movimientos de contraction y expansion del elemento elastico (4), que como se ha indicado estan a su vez gobernados por el movimiento de la palanca de accionamiento (2) por parte del usuario. El elemento impulsor (5) esta vinculado adicionalmente a un soporte de empuje (9), con configuration curvada como se muestra en las figuras 1 y 2, destinado a impulsar un balon (10).Said drive element (5) moves according to the contraction and expansion movements of the elastic element (4), which as indicated are in turn governed by the movement of the operating lever (2) by the user. The driving element (5) is additionally linked to a thrust support (9), with curved configuration as shown in Figures 1 and 2, intended to drive a ball (10).

El mecanismo (1) comprende adicionalmente una gula (11) con un tramo rectillneo (12) y un tramo curvado (13), en cuyo interior se desplaza un rodillo (14) vinculado al elemento impulsor (5). De esta manera, cuando el rodillo (14) se desplaza en el tramo rectillneo (12) de la gula (11), el elemento impulsor (5) se desplaza de manera rectillnea, mientras que si dicho rodillo (14) se desplaza en el tramo curvado (13), el elemento impulsor (5) se desplaza en direction curva.The mechanism (1) additionally comprises a glutton (11) with a straight section (12) and a curved section (13), inside which a roller (14) linked to the driving element (5) moves. In this way, when the roller (14) moves in the straight section (12) of the glutton (11), the driving element (5) moves in a straight way, while if said roller (14) moves in the curved section (13), the driving element (5) moves in a curved direction.

Dicho tramo curvado (13) consta a su vez de un primer sector con curvatura descendente y un segundo sector con curvatura ascendente, y el tramo rectillneo (12) esta conectado por sus extremos a los extremos del tramo curvado (13).Said curved section (13) consists in turn of a first sector with descending curvature and a second sector with ascending curvature, and the straight section (12) is connected at its ends to the ends of the curved section (13).

Se contempla que la palanca de accionamiento (2) se desplace entre las distintas posiciones de un selector de posicion (15), y que al menos el elemento elastico (4) y la gula (11) del mecanismo (1) esten sustentados en un bastidor (16), formado por la union de sendos paneles (17, 17’) paralelos, en el que el bastidor (16) dispone de una base de acoplamiento (18) conIt is contemplated that the operating lever (2) moves between the different positions of a position selector (15), and that at least the elastic element (4) and the glutton (11) of the mechanism (1) are supported by a frame (16), formed by the union of two parallel panels (17, 17 '), in which the frame (16) has a coupling base (18) with

medios de fijacion para acoplarse a una silla de ruedas. Con esta configuration, el dispositivo incorpora sendas guias (11, 11'), una por cada panel (17, 17'), y sendos rodillos (14,14') vinculados al elemento impulsor (5), que se desplazan por dichas guias (11, 11').fixing means for coupling to a wheelchair. With this configuration, the device incorporates two guides (11, 11 '), one for each panel (17, 17'), and two rollers (14,14 ') linked to the drive element (5), which move through said guides (11, 11 ').

Para el caso en que el usuario desee obtener un tiro horizontal, en primer lugar debe desplazar la palanca de accionamiento (2) hasta fijarla en una ranura correspondiente con una primera position de reposo del selector de position (15), tal y como se muestra en la figura 4. Dicho posicionamiento de la palanca de accionamiento (2) provoca un desplazamiento del cable del mecanismo de transmision (3) lo que a su vez comprime al resorte (7) dentro del cilindro (8) del elemento elastico (4).In the case where the user wishes to obtain a horizontal shot, he must first move the operating lever (2) to fix it in a corresponding slot with a first rest position of the position selector (15), as shown in figure 4. Said positioning of the actuation lever (2) causes a shift of the transmission mechanism cable (3) which in turn compresses the spring (7) into the cylinder (8) of the elastic element (4) .

El desplazamiento del resorte (7) hacia un estado de compresion produce a su vez el desplazamiento del elemento impulsor (5), cuyo rodillo (14) desplaza en el tramo rectilmeo (12) de la guia (11).The displacement of the spring (7) towards a compression state in turn causes the displacement of the driving element (5), whose roller (14) displaces in the straight section (12) of the guide (11).

En el instante en que se desea realizar el tiro, el usuario extrae la palanca de accionamiento (2) de la ranura del selector de position (15), que en ese momento se desplaza hasta recuperar su position de reposo inicial, mostrada en la figura 3. Dicho desplazamiento de la palanca de accionamiento (2), mostrado en la figura 5, se debe a la recuperation de la position del resorte (7), al cual esta unida mediante el mecanismo de transmision (3).At the moment in which the shot is desired, the user removes the operating lever (2) from the slot of the position selector (15), which at that time moves until it recovers its initial rest position, shown in the figure 3. Said movement of the actuating lever (2), shown in Figure 5, is due to the recovery of the position of the spring (7), to which it is connected by the transmission mechanism (3).

Esa recuperacion de la posicion del resorte (7) del elemento elastico (4) impulsa a su vez al elemento impulsor (5), con un movimiento rectilmeo que es conservado por el desplazamiento del rodillo (14) dentro del tramo rectilmeo (12) de la guia (11), transmitiendose al soporte de empuje (9), que impulsa al balon (10) con un tiro horizontal.This recovery of the position of the spring (7) of the elastic element (4) in turn drives the impeller element (5), with a straight movement that is conserved by the movement of the roller (14) inside the straight section (12) of the guide (11), being transmitted to the thrust support (9), which drives the ball (10) with a horizontal shot.

Cuando el usuario desee realizar un tiro parabolico, en primer lugar debe desplazar la palanca de accionamiento (2) hasta fijarla en una ranura correspondiente con una segunda position de reposo del selector de position (15), tal y como se muestra en la figura 6. Como se ha indicado para el caso del tiro horizontal, el posicionamiento de la palanca de accionamiento (2) desplaza al cable del mecanismo de transmision (3) y comprime al resorte (7) dentro del cilindro (8).When the user wishes to make a parabolic shot, he must first move the actuation lever (2) to fix it in a corresponding slot with a second rest position of the position selector (15), as shown in Figure 6 As indicated in the case of horizontal shooting, the positioning of the operating lever (2) displaces the transmission mechanism cable (3) and compresses the spring (7) into the cylinder (8).

Por su parte, el elemento impulsor (5) se desplaza hasta una position en la cual su rodillo (14) desplaza dentro del tramo curvado (13) de la guia (11).On the other hand, the driving element (5) moves to a position in which its roller (14) moves within the curved section (13) of the guide (11).

Para efectuar el disparo, el usuario extrae la palanca de accionamiento (2) de la ranura correspondiente con la segunda position, momento en el que el resorte (7) recupera su position de reposo inicial como se ha indicado para el caso del disparo recto. En este caso, el recorrido de recuperation del resorte (7) empuja al elemento impulsor (5), y en consecuencia al soporte de empuje (9) en un primer recorrido descendente, correspondiente con el recorrido del rodillo (14) en el sector de curvatura descendente del tramo curvado (13) de la guia (11), como se muestra en la figura 7. En este primer recorrido, por tanto, el soporte de empuje (9) desciende para acoger al balon (10).To carry out the trip, the user removes the operating lever (2) from the corresponding slot with the second position, at which time the spring (7) recovers its initial rest position as indicated in the case of the straight shot. In this case, the recovery path of the spring (7) pushes the driving element (5), and consequently the thrust support (9) in a first downward travel, corresponding to the roller travel (14) in the sector of descending curvature of the curved section (13) of the guide (11), as shown in figure 7. In this first path, therefore, the thrust support (9) descends to accommodate the ball (10).

El tramo final del recorrido de recuperation del resorte (7) hasta volver a su position de reposo coincide con el que recorre el rodillo (14) en el sector de curvatura ascendente del tramo curvado (13) de la guia (11), como se muestra en la figura 8. En este segundo recorrido, el soporte de empuje (9) impulsa al balon (10), que estaba sustentado en su estructura, mediante un tiro parabolico.The final section of the spring recovery path (7) until it returns to its resting position coincides with the one that runs the roller (14) in the sector of ascending curvature of the curved section (13) of the guide (11), as shown in figure 8. On this second path, the thrust support (9) drives the ball (10), which was supported in its structure, by a parabolic shot.

En la realization preferente, el dispositivo impulsor de balon en silla de ruedas comprende dos mecanismos (1, 1') acoplados a una silla de ruedas mediante la base de acoplamiento (18), siendo ambos mecanismos (1, 1') simetricos entre si respecto a un plano longitudinal pasante por el centro de la silla de ruedas tal y como se muestra en la figura 1.In the preferred embodiment, the wheelchair ball drive device comprises two mechanisms (1, 1 ') coupled to a wheelchair by the coupling base (18), both mechanisms (1, 1') being symmetrical with each other. with respect to a longitudinal plane passing through the center of the wheelchair as shown in figure 1.
