ANDADOR-SUBIDOR PARA PERSONAS CON DISCAPACIDAD EN UNA DE  WALKER-SUBIDOR FOR PEOPLE WITH DISABILITIES IN ONE OF

SUS PIERNAS HIS LEGS

DESCRIPCIÓN DESCRIPTION

Objeto de la Invención  Object of the Invention

La presente invención se refiere a un andador-subidor para personas con discapacidad en una de sus piernas, que permite la funcionalidad adicional de subir obstáculos del tipo de bordillos o escaleras. The present invention relates to a walker-climber for people with disabilities on one of its legs, which allows the additional functionality of climbing obstacles of the type of curbs or stairs.

Antecedentes de la invención En la actualidad se conocen andadores para personas con discapacidad, que básicamente comprenden una estructura donde la persona se apoya con sus brazos o manos, y la cual está dotada de medios de rodadura lo que permite deambular con la seguridad que aporta el poder sujetarse a la estructura para mantenerse de pie. Estos andadores tienen el inconveniente de que no son utilizables por personas con discapacidad en una de sus piernas ni tampoco son adecuados para subir bordillos, y mucho menos escaleras. Por esta razón lo habitual en personas con este tipo de discapacidad es utilizar muletas o sillas de ruedas. En el caso de las muletas se requiere una cierta forma física, lo que limita su utilización especialmente en personas de cierta edad. Además, a la hora de subir y bajar escaleras los dos puntos de apoyo de ambas muletas cuando la pierna de apoyo está en el aire no proporcionan muchas veces una estabilidad y seguridad suficiente. BACKGROUND OF THE INVENTION Currently, walkers are known for people with disabilities, who basically comprise a structure where the person rests with their arms or hands, and which is equipped with rolling means which allows to wander around with the security provided by the be able to hold on to the structure to stand up. These walkers have the disadvantage that they are not usable by people with disabilities on one of their legs nor are they suitable for climbing curbs, much less stairs. For this reason the usual thing in people with this type of disability is to use crutches or wheelchairs. In the case of crutches a certain physical form is required, which limits its use especially in people of a certain age. Furthermore, when it comes to going up and down the stairs, the two support points of both crutches when the support leg is in the air do not provide sufficient stability and security.

Por otro lado, una silla de ruedas solo permite deambular por terrenos llanos o con rampas de pendiente poco acusada, y por lo tanto no permiten subir bordillos o escaleras, lo que supone un aumento de las condiciones de dependencia del usuario en comparación con la utilización del andador-subidor de la invención. Descripción de la invención On the other hand, a wheelchair only allows you to wander through flat terrain or with ramps of little steep slope, and therefore do not allow you to climb curbs or stairs, which means an increase in the conditions of dependence of the user compared to the use of the walker-subway of the invention. Description of the invention

El andador-subidor para personas con discapacidad en una de sus piernas de la invención tiene una constitución que subsana los inconvenientes descritos, ya que por un lado permite su utilización por cualquier persona, y por otro lado permite salvar obstáculos tales como escaleras o bordillos, y no tiene la aparatosidad ni el coste de una silla de ruedas. Además proporciona mayores prestaciones que unas muletas o un andador convencional, aumentando considerablemente la autonomía del usuario. The walker-climber for people with disabilities on one of its legs of the invention has a constitution that remedies the described inconveniences, since on the one hand it allows its use by any person, and on the other hand it allows to overcome obstacles such as stairs or curbs, and it does not have the apparatus or the cost of a wheelchair. It also provides greater benefits than some crutches or a conventional walker, greatly increasing user autonomy.

De acuerdo con la invención, el andador-subidor en su configuración esencial comprende una estructura dotada de una bandeja superior con medios de sujeción del muslo y/o pierna, unos medios de rodadura de dicha estructura, y unos medios de anulación de los medios de rodadura. According to the invention, the walker-climber in its essential configuration comprises a structure provided with an upper tray with means for securing the thigh and / or leg, rolling means of said structure, and means for canceling the means of rolling

El muslo y/o la pierna queda apoyado o apeado sobre la bandeja superior, a la que se sujeta mediante los medios de sujeción. Este apoyo permite mantener el muslo y la pierna en la posición más propicia que la discapacidad, comodidad o las indicaciones médicas requieran, mientras que los medios de rodadura permiten deambular a usuario con la ayuda de la otra pierna. The thigh and / or leg is supported or attached to the upper tray, to which it is attached by means of support. This support allows keeping the thigh and leg in the most propitious position that the disability, comfort or medical indications require, while the rolling means allow the user to roam with the help of the other leg.

Para salvar un obstáculo como un escalón, o subir una escalera, se apoya primero la pierna sana en la parte superior del escalón o bordillo gracias al apoyo estable e inmovilizado que, a través de la otra pierna, proporciona el andador-subidor de la invención cuando están anulados los medios de rodadura. A continuación se sube la pierna discapacitada y con ello también el andador-subidor ya que se encuentra fijado a la misma, y asi sucesivamente. Además las manos del usuario quedan libres, lo que le permite usar las mismas para ayudarse con el pasamanos de la escalera, si dispone del mismo. To overcome an obstacle such as a step, or climb a ladder, the healthy leg is supported first on the top of the step or curb thanks to the stable and immobilized support that, through the other leg, provides the walker-climber of the invention when they are canceled The rolling means. Next the disabled leg is raised and with it also the walker-climber since it is fixed to it, and so on. In addition, the user's hands are free, which allows them to use them to help with the handrail of the ladder, if available.

Sobre esta configuración esencial se pueden añadir otras funcionalidades, tales como la regulación de inclinación o longitudinal de la bandeja respecto de la estructura, que redundarán en una mayor comodidad y ergonomia de uso. Other functionalities can be added to this essential configuration, such as the inclination or longitudinal adjustment of the tray with respect to the structure, which will result in greater comfort and ergonomics of use.

Descripción de la Forma de Realización Preferida Description of the Preferred Embodiment

El andador-subidor para personas con discapacidad en una de sus piernas de la invención comprende una estructura (1) dotada de una bandeja superior (2) con medios de sujeción del muslo (20) y/o pierna, unos medios de rodadura de dicha estructura (1), y unos medios de anulación de los medios de rodadura. El muslo (20) se apoya sobre la bandeja superior (2), a la que se sujeta mediante los medios de sujeción -típicamente unas correas (12) ajustables-, lo que mantiene la pierna en la posición profiláctica adecuada, sin contacto con el suelo, mientras que los medios de rodadura permiten deambular a usuario con la ayuda de la otra pierna (30) . The walker-climber for people with disabilities on one of its legs of the invention comprises a structure (1) provided with an upper tray (2) with means for securing the thigh (20) and / or leg, rolling means of said structure (1), and means for canceling the rolling means. The thigh (20) rests on the upper tray (2), to which it is secured by means of fasteners - typically adjustable straps (12) -, which keeps the leg in the proper prophylactic position, without contact with the ground, while the rolling means allow the user to roam with the help of the other leg (30).

A la hora de salvar un obstáculo como un escalón, o de subir una escalera (40) , se hacen actuar los medios de anulación de los medios de rodadura. Esto proporciona a la estructura (1) un apoyo fijo en el bordillo o escalón, de forma que los impulsos realizados con la extremidad fijada a la misma se transmiten directamente y sin pérdidas y permitir salvar el obstáculo con seguridad. En la Figura 4 puede apreciarse la utilización del andador-subidor subiendo una escalera (40) con un pasamanos (41) . Para bajar es al contrario, se baja primero la pierna discapacitada apoyando la estructura (1) en el peldaño o firme inferior, y a continuación la pierna buena Adicionalmente la invención ha previsto que la bandeja superior (2) implemente medios de ajuste en inclinación y/o de ajuste longitudinal. Los medios de ajuste longitudinal permiten variar la posición del centro de gravedad del usuario respecto a los puntos de rodadura/apoyo de la estructura (1), por ejemplo avanzando el centro de gravedad a la hora de subir un bordillo o escalera para favorecer la transmisión de esfuerzos. Los medios de ajuste en inclinación permiten graduar la inclinación del muslo (20) , según la comodidad del usuario o indicaciones terapéuticas. Con este mismo fin la bandeja superior (2) puede comprender una extensión (3) ajustable en inclinación delantera para acomodo de la pierna (21) (ver figuras 1 y 2) . When removing an obstacle such as a step, or climbing a ladder (40), the means for canceling the rolling means are operated. This provides the structure (1) with a fixed support on the curb or step, so that the impulses made with the limb fixed to it are transmitted directly and without losses and allow the obstacle to be safely saved. Figure 4 shows the use of the walker-climber by climbing a ladder (40) with a handrail (41). To lower it, on the contrary, the disabled leg is lowered first, supporting the structure (1) on the lower step or firm, and then the good leg. Additionally, the invention has provided that the upper tray (2) implements inclination adjustment means and / or longitudinal adjustment. The longitudinal adjustment means allow varying the position of the center of gravity of the user with respect to the rolling / support points of the structure (1), for example advancing the center of gravity when climbing a curb or ladder to favor transmission of efforts. The inclination adjustment means allow to adjust the inclination of the thigh (20), according to the comfort of the user or therapeutic indications. For this same purpose the upper tray (2) may comprise an extension (3) adjustable in front inclination to accommodate the leg (21) (see figures 1 and 2).

Para facilitar la orientación y manejo de la estructura (1) se ha previsto la disposición opcional de unas asas (5) en la misma como se ve en la figura 1. Además, la estructura (1) comprende medios de ajuste en altura para adaptarse a la talla del usuario. Dichos medios de ajuste en altura comprenden, en este ejemplo no limitativo de la invención, tramos telescópicos (6) con pasadores (6a) de enclavamiento de su extensión, interpuestos entre la bandeja superior (2) y el resto de la estructura (1) . Por su parte, los medios de rodadura comprenden ruedas giratorias direccionalmente (7) y/o ruedas fijas (8) . En el ejemplo mostrado en las figuras las ruedas giratorias direccionalmente se ubican en la zona anterior de la estructura, y las fijas detrás, aunque se pueden colocar indistintamente, e incluso que todas las ruedas sean fijas o giratorias, o incluso giratorias bloqueables en giro. In order to facilitate the orientation and handling of the structure (1), the optional arrangement of handles (5) is provided therein as seen in Figure 1. In addition, the structure (1) comprises height adjustment means to adapt to the size of the user. Said height adjustment means comprise, in this non-limiting example of the invention, telescopic sections (6) with interlocking pins (6a) interposed between the upper tray (2) and the rest of the structure (1) . On the other hand, the rolling means comprise directionally rotating wheels (7) and / or fixed wheels (8). In the example shown in the figures, the directionally rotating wheels are located in the anterior area of the structure, and the fixed ones behind, although they can be placed interchangeably, and even that all the wheels are fixed or rotating, or even swivel lockable.

Para la materialización de la estructura (1) en este ejemplo de realización preferente se ha elegido una configuración que comprende una tijera plegable. Además de la facilidad de plegado, esta configuración permite implementar los medios de anulación de los medios de rodadura implementando un mecanismo de regulación de la apertura de la tijera en dos posiciones: una primera posición de rodadura donde sus partes o mitades (la, Ib) forman un ángulo mayor tal que las ruedas (7, 8) se encuentran en contacto con el suelo, y una segunda posición de bloqueo donde ambas mitades (la, Ib) forman un ángulo menor tal que las ruedas (7, 8) se encuentran elevadas respecto al suelo y los extremos de ambas mitades (la, Ib) de la tijera se encuentran en contacto con el suelo a través de conteras (9) antideslizantes. La figura 2 muestra en su primera vista la posición de rodadura, en su cuarta vista la posición de bloqueo, y en las vistas segunda y tercera etapas intermedias de transición entre las dos posiciones anteriores. Concretamente, en la posición de bloqueo la amplitud de la parte inferior de la tijera se encuentra preferentemente comprendida entre 22 y 28 cm, para caber en las dimensiones de la huella de una escalera típica. For the materialization of the structure (1) in this preferred embodiment, a configuration comprising a folding scissor has been chosen. In addition to the ease of folding, this configuration allows the means of cancellation of the rolling means to be implemented by implementing a mechanism for regulating the opening of the scissors in two positions: a first rolling position where its parts or halves (la, Ib) they form a greater angle such that the wheels (7, 8) are in contact with the ground, and a second locking position where both halves (la, Ib) form a smaller angle such that the wheels (7, 8) meet high relative to the ground and the ends of both halves (la, Ib) of the scissors are in contact with the ground through non-slip tips (9). Figure 2 shows in its first view the rolling position, in its fourth view the locking position, and in the second and third intermediate transition stages views between the two previous positions. Specifically, in the locked position the amplitude of the lower part of the scissors is preferably between 22 and 28 cm, to fit in the dimensions of the footprint of a typical ladder.

Para materializar el mecanismo de regulación de la apertura de la tijera se ha previsto preferentemente la disposición de una bieleta (10) extrema articulada por un lado a la parte superior de una de las mitades (la) de la tijera y por el otro a la bandeja superior (2), mientras que la otra mitad de la tijera (Ib) se articula superiormente a la bandeja superior. Provocando el giro de la bieleta (10) mediante un movimiento semicircular, se consigue acortar o ampliar la apertura de la tijera, y esta variación de geometría consigue el contacto con el suelo de ruedas (7, 8) o alternativamente de las conteras (9) . En el caso mostrado en las figuras, el giro de la bieleta (10) se realiza mediante una palanca (11), y también se ha previsto la fijación de las posiciones extremas de la misma mediante medios tales como enclavamientos mecánicos y/o atracción por imanes (14a) . Concretamente en la figura 3 se aprecian unos imanes (14a). En cuanto a la palanca (11), se ha previsto que sea intercambiable para poder manejar el mecanismo con la mano más favorable, en función de la pierna afectada. Igualmente el accionamiento mediante palanca puede incluir una multiplicación por engranajes, no representados, de forma que, por ejemplo, accionando la palanca (11) en un cuarto de vuelta se produzca el movimiento semicircular completo, correspondiente a media vuelta, de la bieleta (10) . In order to realize the mechanism for regulating the opening of the scissors, the provision of an end link (10) articulated on one side to the top of one of the halves (the) of the scissors and on the other to the other is preferably provided. upper tray (2), while the other half of the scissors (Ib) articulates superiorly to the upper tray. By provoking the rotation of the connecting rod (10) by means of a semicircular movement, it is possible to shorten or expand the opening of the scissors, and this variation of geometry achieves contact with the wheel ground (7, 8) or alternatively of the beams (9 ). In the case shown in the figures, the rotation of the connecting rod (10) is carried out by means of a lever (11), and the fixing of the extreme positions thereof by means such as mechanical interlocks and / or attraction by magnets (14a). Specifically in figure 3 magnets (14a) can be seen. As for the lever (11), it is intended to be interchangeable in order to handle the mechanism with the most favorable hand, depending on the affected leg. Likewise, the lever operation can include multiplication by gears, not shown, so that, for example, by operating the lever (11) in a quarter turn, the complete semicircular movement, corresponding to half turn of the connecting rod (10).

Otra forma de implementar los medios de anulación de la rodadura seria la disposición de ruedas bloqueables de cualquier tipo de las existentes en el mercado (con frenos o enclavamientos) . Another way to implement the means of cancellation of the rolling would be the provision of lockable wheels of any type existing in the market (with brakes or interlocks).

Los medios de ajuste longitudinal de la bandeja superior (2) pueden materializarse de cualquier forma existente en el estado de la técnica, por ejemplo como se muestra en la figura 3, mediante la disposición de patines (16) solidarios a un sector extremo (2a) de la bandeja superior (2) que discurran por guias (17) que sean las que se articulen a las mitades superiores (la, Ib) de la tijera que conforma la estructura (1) . The longitudinal adjustment means of the upper tray (2) can be realized in any way existing in the state of the art, for example as shown in Figure 3, by means of the arrangement of skates (16) integral with an end sector (2a ) of the upper tray (2) that run by guides (17) that are those that are articulated to the upper halves (la, Ib) of the scissors that make up the structure (1).

Igualmente los medios de ajuste de la inclinación de la bandeja superior pueden configurarse de múltiples formas, si bien se puede aprovechar la interposición de los tramos telescópicos (6) de ajuste de la altura de la bandeja superior (2) y regularlos a distintas alturas en la parte anterior y posterior. Likewise, the means for adjusting the inclination of the upper tray can be configured in multiple ways, although it is possible to take advantage of the interposition of the telescopic sections (6) for adjusting the height of the upper tray (2) and adjust them to different heights in the front and back.

Por último la invención ha previsto que se puedan incorporar en la zona más favorable, y típicamente en la parte inferior de la estructura (1), unos sensores, no representados, que monitoricen el correcto apoyo de la estructura (1) en el bordillo o peldaño, asociados a indicadores sonoros o visuales, lo que permitirá al usuario conocer si la estructura está correctamente apoyada antes de impulsarse. Por ejemplo, en la estructura mostrada en las figuras, dichos sensores pueden comprender un sensor de presión en cada una de las conteras de apoyo en el peldaño. No obstante lo anterior, y puesto que la descripción realizada corresponde únicamente a un ejemplo de realización preferida de la invención, se comprenderá que dentro de su esencialidad podrán introducirse múltiples variaciones de detalle, asimismo protegidas, que podrán afectar a la forma, el tamaño o los materiales de fabricación del conjunto o de sus partes, sin que ello suponga alteración alguna de la invención en su conjunto, delimitada únicamente por las reivindicaciones que se proporcionan en lo que sigue. Finally, the invention has provided that sensors, not shown, that monitor the correct support of the structure (1) on the curb or can be incorporated in the lower part of the structure (and typically in the lower part of the structure). step, associated with sound or visual indicators, which will allow the user to know if the structure is correctly supported before being driven. For example, in the structure shown in the figures, said sensors may comprise a pressure sensor in each of the support beams on the step. Notwithstanding the foregoing, and since the description made only corresponds to a preferred embodiment of the invention, it will be understood that within its essentiality multiple variations of detail may be introduced, also protected, which may affect the shape, size or manufacturing materials of the assembly or its parts , without implying any alteration of the invention as a whole, delimited only by the claims provided in the following.
