Silla de ruedas para caminos difícilesWheelchair for difficult roads
SECTOR DE LA TÉCNICATECHNIQUE SECTOR
La presente invención se refiere a una silla de ruedas para recorrido en caminos poco practicables, por ejemplo, en montañismo. Por lo tanto es utilizable por personas con movilidad reducida en el tren inferior, ya sea aquejados de parálisis de las extremidades inferiores, pérdida de miembros o lesiones de cualquier tipo.The present invention refers to a wheelchair for travel on paths that are not very practicable, for example, in mountaineering. Therefore, it can be used by people with reduced mobility in the lower body, whether they suffer from paralysis of the lower extremities, loss of limbs or injuries of any kind.
Es de aplicación en el campo del deporte adaptado, para caminos en los que no puede circular una silla de ruedas tradicional u otro tipo de vehículo adaptado. Para facilitar la movilidad y la práctica deportiva o el disfrute del actividades de ocio en la naturaleza.It is applicable in the field of adapted sports, for roads where a traditional wheelchair or other type of adapted vehicle cannot circulate. To facilitate mobility and sports practice or the enjoyment of leisure activities in nature.
ESTADO DE LA TÉCNICASTATE OF THE ART
Las personas con algún tipo de lesión en el tren inferior, especialmente si su gravedad les obliga a ir en silla de ruedas, están limitadas en su movimiento a los lugares por donde pueda pasar la silla. Sin embargo, el desarrollo de diversos tipos de deporte adaptados para personas con discapacidad ha aumentado exponencialmente sus posibilidades. Se encuentran ya en el mercado sillas de grandes prestaciones para carreras cortas o largas, para grandes recorridos, etc. En terrenos llanos y asfaltados. Sin embargo, en entornos naturales, laderas, montañas, selva o nieve con elevadas pendientes y terrenos rocosos o empedrados no hay una silla que facilite la movilidad y las que existen se siguen encontrando limitadas por la necesidad de un camino con las condiciones de anchura, de firmeza del suelo y de pendiente que les permita el ascenso.People with some type of lower body injury, especially if their severity requires them to use a wheelchair, are limited in their movement to places where the chair can pass. However, the development of various types of sports adapted for people with disabilities has exponentially increased their possibilities. There are already high-performance chairs on the market for short or long races, for long journeys, etc. On flat and paved terrain. However, in natural environments, slopes, mountains, jungle or snow with high slopes and rocky or cobbled terrain, there is no chair that facilitates mobility and those that exist are still limited by the need for a path with the conditions of width, firmness of the ground and slope that allows them to climb.
Si el deportista desea realizar algún tipo de ascenso o de recorrido que no cumple las condiciones, necesita una silla de ruedas que pueda ser utilizada en caminos poco practicables y que posea elementos de ayuda para permitir el desplazamiento por sus propios medios, o si acaso con el mínimo de asistencia en la preparación del camino.If the athlete wishes to carry out some type of ascent or route that does not meet the conditions, he needs a wheelchair that can be used on roads that are not very practicable and that has aid elements to allow movement by his own means, or perhaps with the minimum of assistance in the preparation of the path.
El solicitante no conoce ninguna silla de ruedas similar a la invención, que permita circular por casi cualquier camino (incluido roca y pendiente) adaptado a personas sin problemas de movilidad. Es decir, que se independiza de la pendiente y de las condiciones del firme.The applicant is not aware of any wheelchair similar to the invention, which allows movement on almost any path (including rock and slope) adapted to people without mobility problems. That is, it is independent of the slope and the conditions of the pavement.
El documento US5624128 describe una silla de ruedas para caminos poco transitables con una serie de ruedas.Document US5624128 describes a wheelchair for rough roads with a series of wheels.
BREVE EXPLICACIÓN DE LA INVENCIÓNBRIEF EXPLANATION OF THE INVENTION
La invención consiste en una silla de ruedas utilizable en caminos poco practicables, como en montañismo, según las reivindicaciones. Permite el avance en situación de pendiente y está principalmente destinada a personas con movilidad reducida en el tren inferior.The invention consists of a wheelchair that can be used on difficult paths, such as mountaineering, according to the claims. It allows progress on slopes and is mainly intended for people with reduced mobility in the lower body.
La silla está prevista para utilizarse en caminos muy estrechos, con mucha pendiente (hasta 60%) o con muchas piedras. Este tipo de caminos no es accesible o practicable para otro tipo de sillas de ruedas o para "handbikes”. Por lo tanto, la silla de la invención aumenta la autonomía a las personas con movilidad reducida.The chair is designed to be used on very narrow paths, with a steep slope (up to 60%) or with many stones. This type of path is not accessible or practicable for other types of wheelchairs or for "handbikes". Therefore, the chair of the invention increases the autonomy of people with reduced mobility.
La silla posee un asiento portado por una serie de ruedas, como es habitual, pero estas ruedas están dispuestas de forma diferente. Dispone de dos ruedas posteriores inclinadas, dispuestas por detrás del asiento, y que convergen en su parte superior trasera. Es decir, no son paralelas y su punto más próximo está en la zona posterior y superior de las ruedas. De forma que pueda adentrarse en caminos muy estrechos y como punto de apoyo en el ascenso entre rocas y piedras. Además, delante del asiento se dispone una extensión longitudinal frontal que soporta una rueda frontal, con giro loco. De esta forma se forma un apoyo en tres puntos, que es muy estable. Dado que la rueda frontal gira loca, su tamaño será preferiblemente reducido para que no deforme demasiado la zona de apoyo del conjunto.The chair has a seat carried by a series of wheels, as usual, but these wheels are arranged differently. It has two inclined rear wheels, arranged behind the seat, and which converge at its upper rear part. That is, they are not parallel and their closest point is in the rear and upper area of the wheels. So that it can enter very narrow paths and as a point of support in the ascent between rocks and stones. In addition, a front longitudinal extension is arranged in front of the seat which supports a front wheel, with idle turning. In this way, a three-point support is formed, which is very stable. Since the front wheel rotates wildly, its size will preferably be reduced so that it does not deform the support area of the assembly too much.
La extensión también dispone de un manillar fijo en una posición enfrentada al asiento. Que puede ser utilizado para incluir complementos opcionales, como focos, sensores de inclinación (longitudinal y/o transversal), botellas de agua, pulsadores de frenos para la rueda frontal, etc. The extension also features a fixed handlebar in a position facing the seat. That can be used to include optional accessories, such as spotlights, inclination sensors (longitudinal and/or transversal), water bottles, brake buttons for the front wheel, etc.
La silla también posee una rueda de empuje a cada lado del asiento, generalmente paralelas, para autopropulsarse, y preferiblemente desmontables. Más preferiblemente, su parte inferior estará en un plano inferior a las ruedas posteriores.The chair also has a push wheel on each side of the seat, generally parallel, for self-propulsion, and preferably removable. More preferably, its lower part will be in a lower plane than the rear wheels.
Preferiblemente, la extensión soporta unos estribos de fijación de los pies del usuario.Preferably, the extension supports brackets for fixing the user's feet.
En una realización más preferida, la extensión soporta un acople para un cable, cuerda o similar, que permite que el usuario avance en terrenos difíciles con técnicas similares a la escalada sin necesidad de las ruedas de empuje tradicionales. El cable puede ser recogido en un tambor o aspirador.In a more preferred embodiment, the extension supports an attachment for a cable, rope, or the like, which allows the user to progress over difficult terrain with climbing-like techniques without the need for traditional push wheels. The cable can be collected in a drum or vacuum.
Otras variantes serán comentadas en otros puntos de la memoria.Other variants will be discussed at other points in memory.
DESCRIPCIÓN DE LOS DIBUJOSDESCRIPTION OF THE DRAWINGS
Se presenta una serie de figuras para facilitar la comprensión de la invención:A series of figures is presented to facilitate the understanding of the invention:
Figura 1: vista lateral esquemática de un ejemplo de realización.Figure 1: schematic side view of an exemplary embodiment.
Figura 2: vista superior del esquema de un segundo ejemplo de realización.Figure 2: Top view of the schematic of a second embodiment.
MODOS DE REALIZACIÓN DE LA INVENCIÓNMODES OF CARRYING OUT THE INVENTION
A continuación se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta.An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.
La silla de la realización mostrada en las figuras comprende un asiento (1), preferiblemente estrecho y con un arnés o cinturón de seguridad, portado por una serie de ruedas (2,3,4) que se clasifican en varios tipos:The chair of the embodiment shown in the figures comprises a seat (1), preferably narrow and with a harness or safety belt, carried by a series of wheels (2,3,4) that are classified into several types:
- Dos ruedas de empuje (2) generalmente paralelas y aproximadamente verticales, dispuestas a ambos lados del asiento (1). Corresponden a las ruedas de sillas de ruedas tradicionales para autopropulsión. Idealmente serán desmontables para poder reducir el ancho efectivo de la silla.- Two thrust wheels (2) generally parallel and approximately vertical, arranged on both sides of the seat (1). They correspond to the wheels of traditional self-propelled wheelchairs. Ideally they will be removable in order to reduce the effective width of the chair.
- Una rueda frontal (3), dispuesta por delante del asiento (1), en una extensión (5) frontal. Esta rueda frontal (3) girará preferiblemente loca sobre un eje vertical para poder orientarse en cualquier dirección. Se podrá incluir un limitador de ángulo de orientación que bloquee la rueda frontal (5) en posición o que limite las orientaciones posibles a un ángulo preciso.- A front wheel (3), arranged in front of the seat (1), in a frontal extension (5). This front wheel (3) will preferably rotate loosely on a vertical axis to be able to orient itself in any direction. A speed limiter may be included. orientation angle that locks the front wheel (5) in position or that limits the possible orientations to a precise angle.
- Dos ruedas posteriores (4) inclinadas, dispuestas por detrás del asiento (1). Las ruedas posteriores (4) poseen una doble inclinación para converger a su parte superior trasera. Es decir, por un lado, convergen en su parte superior (la zona superior de ambas ruedas posteriores (4) está más próxima al eje longitudinal de la silla que la zona inferior), y por otro lado, convergen en su parte posterior (el extremo posterior del diámetro horizontal de las ruedas posteriores (4) está más próximo al eje longitudinal de la silla que el extremo anterior).- Two inclined rear wheels (4), arranged behind the seat (1). The rear wheels (4) have a double inclination to converge to their upper rear part. That is to say, on the one hand, they converge at the top (the upper area of both rear wheels (4) is closer to the longitudinal axis of the chair than the lower area), and on the other hand, they converge at the rear (the rear end of the horizontal diameter of the rear wheels (4) is closer to the longitudinal axis of the chair than the front end).
Las ruedas posteriores (4) estarán más elevadas que las ruedas de empuje (2), para que sólo toquen el suelo si la silla está inclinada hacia atrás o si se han desmontado las ruedas de empuje (2). Así, en la segunda situación, bajarán el centro de gravedad del conjunto para aumentar la estabilidad. Si se desea, las ruedas posteriores (4), o cualquier otra rueda (2,3,4) o eje, contarán con un equipo de suspensión o amortiguación.The rear wheels (4) will be higher than the push wheels (2), so that they only touch the ground if the chair is tilted backwards or if the push wheels (2) have been removed. Thus, in the second situation, they will lower the center of gravity of the assembly to increase stability. If desired, the rear wheels (4), or any other wheel (2,3,4) or axle, will have suspension or damping equipment.
La extensión (5) de esta realización se aprecia especialmente en la figura 1. Consiste en un perfil horizontal unido a la parte inferior del asiento (1) y rematado en la rueda frontal (3). Del perfil surge un manillar (6) fijo que estará dispuesto en un punto fácil de alcanzar para el usuario de la silla. Sirve para que la persona de movilidad reducida apoye los brazos y tenga una postura cómoda.The extension (5) of this embodiment can be seen especially in figure 1. It consists of a horizontal profile attached to the lower part of the seat (1) and finished off at the front wheel (3). A fixed handlebar (6) emerges from the profile, which will be arranged at a point that is easy to reach for the user of the chair. It is used for the person with reduced mobility to support their arms and have a comfortable posture.
En ese manillar (6) se puede situar un sensor de inclinación (giroscopio, acelerómetro, nivel de burbuja, ...) que permita al usuario saber la inclinación de la silla en los ejes longitudinal y transversal y por lo tanto el riesgo de vuelco. También se podrá colocar un freno, con cable Bowden, para la rueda frontal (3) o para las ruedas de empuje (2). La silla puede llevar incorporada una cámara 360° para grabar y estudiar el terreno, un GPS y brújula pivotante, así como sombrillas, motores eléctricos de apoyo (en las ruedas de empuje (2) preferiblemente), baterías y un panel solar de recarga de éstas.An inclination sensor (gyroscope, accelerometer, spirit level,...) can be placed on this handlebar (6) which allows the user to know the inclination of the chair in the longitudinal and transversal axes and therefore the risk of tipping. . A brake can also be fitted, with a Bowden cable, for the front wheel (3) or for the push wheels (2). The chair can incorporate a 360° camera to record and study the terrain, a GPS and a pivoting compass, as well as umbrellas, electric support motors (preferably on the push wheels (2)), batteries and a solar panel to recharge are.
La silla lleva, por ejemplo en el manillar (6) o delante de éste, un acople (7) para un cable (8) o similar que permite anclar la silla a un punto fijo. De esta forma se puede instalar una vía de seguridad o línea de vida, similar a las utilizadas en escalada. Más aún, este cable (8) permite al usuario de la silla subir a pulso, tirando o recogiéndolo. La recogida puede ser en un tambor con sendas manivelas para giro manual, motorizado, a pulso, o mediante la técnica de escalada de "cuerda y puño”. Si el cable (8) no queda recogido en ese punto, se puede realizar un sistema de recogida por detrás del asiento, o a su altura. Ese sistema de recogida puede ser un tambor con un resorte de poca potencia, que recoja el cable (8) destensado o un aspirador.The chair has, for example on the handlebar (6) or in front of it, a coupling (7) for a cable (8) or the like that allows the chair to be anchored to a fixed point. In this way, a safety route or lifeline can be installed, similar to those used in climbing. Furthermore, this cable (8) allows the user of the chair to climb freehand, pulling or picking it up. The collection can be in a drum with separate cranks for manual, motorized, pulse, or by means of the "rope and fist" climbing technique. If the cable (8) is not collected at that point, a collection system can be made behind the seat, or at its height. This collection system can be a drum with a light spring, which collects the slack cable (8), or a vacuum cleaner.
Una solución más complicada de realizar es definir un garfio en un extremo del cable (8) que permita anclar la silla, o incluso un sistema de lanzamiento de ese cable (8).A more complicated solution to implement is to define a hook at one end of the cable (8) that allows the chair to be anchored, or even a launching system for that cable (8).
Se aprecia en las figuras que la extensión (5) comprende unos estribos (9) de fijación de los pies del usuario, e igualmente puede tener una fijación para las rodillas. De esta forma se asegura que no hay movimientos descontrolados del tren inferior.It can be seen in the figures that the extension (5) includes stirrups (9) for fixing the feet of the user, and it can also have a fixation for the knees. In this way it is ensured that there are no uncontrolled movements of the lower body.
La silla de las figuras comprende un asidero (10) en la parte posterior que permite que un acompañante del usuario le asista en momentos puntuales. Por un lado permite ayudar a colocar la silla en la posición de inicio y por otro lado permitirá compensar o frenar el volcado de la silla. Esta función también es satisfecha por el manillar (6), en el extremo opuesto de la silla. Un asa (11) en la parte anterior, ayuda a mover y orientar la silla hasta la posición inicial.The chair in the figures includes a handle (10) on the back that allows a companion of the user to assist him at specific times. On the one hand, it helps to place the chair in the starting position and, on the other hand, it allows to compensate or stop the tipping of the chair. This function is also fulfilled by the handlebar (6), at the opposite end of the chair. A handle (11) in the front part helps to move and guide the chair to the initial position.
Es conveniente reducir al máximo el peso de la silla, por lo que las piezas se reducirán al máximo y se escogerán materiales ligeros.It is convenient to minimize the weight of the chair, so the pieces will be reduced to the maximum and light materials will be chosen.
La silla podrá ser montable por el usuario o sus compañeros, pudiendo suministrarse como un kit de construcción tipo mecano, con las piezas en una maleta, y con piezas de recambio y sustitución. The chair may be assembled by the user or his colleagues, and may be supplied as a mechanical-type construction kit, with the parts in a suitcase, and with spare and replacement parts.
