Description

Reposapiés para una silla de ruedas. Footrest for a wheelchair.

Campo de la invención. Field of the invention.

La presente invención se refiere a un reposapiés para una silla de ruedas, cuyo reposapiés está configurado con el fin de prevenir las lesiones del usuario cuando éste se caiga accidentalmente e impacte violentamente contra dicho reposapiés. The present invention relates to a footrest for a wheelchair, whose footrest is configured in order to prevent user injuries when it accidentally falls and violently impacts said footrest.

Antecedentes de la invención Background of the invention

Las sillas de ruedas convencionales están dotadas comúnmente de dos reposapiés destinados a soportar cada pie de la persona que use la silla. Dichos reposapiés están montados en la parte frontal de la silla y en cualquiera de los dos lados de la silla de ruedas con el fin de formar un soporte plano para los pies del usuario cuando éste se sienta en la silla de ruedas. Ventajosamente, cada reposapiés se podría dotar comúnmente de una banda para el talón, cuya banda esté configurada para soportar el talón del pie del usuario. Dicha banda se extiende generalmente en la parte posterior del reposapiés y en una posición ortogonal con respecto a la plataforma del reposapiés. La banda generalmente se aloja sobre uno o varios postes metálicos unidos fijamente a la plataforma del reposapiés y posicionados cerca de las esquinas de la plataforma del reposapiés. Tal configuración se ha usado normalmente en las sillas de ruedas convencionales durante mucho tiempo. Sin embargo, esta configuración podría constituir un riesgo para el usuario si éste accidentalmente se cae de la silla de ruedas e impacta violentamente contra los reposapiés con su trasero, por ejemplo. De hecho, en este caso, hay muchas probabilidades de que el usuario resulte seriamente lesionado por los postes metálicos de los reposapiés. Conventional wheelchairs are commonly equipped with two footrests designed to support each foot of the person using the chair. Said footrests are mounted on the front of the chair and on either side of the wheelchair in order to form a flat support for the user's feet when he or she sits in the wheelchair. Advantageously, each footrest could commonly be provided with a heel band, the band of which is configured to support the heel of the user's foot. Said band generally extends at the rear of the footrest and in an orthogonal position with respect to the footrest platform. The band is generally housed on one or several metal posts fixedly attached to the footrest platform and positioned near the corners of the footrest platform. Such a configuration has normally been used in conventional wheelchairs for a long time. However, this configuration could be a risk for the user if he accidentally falls off the wheelchair and violently hits the footrests with his rear end, for example. In fact, in this case, there is a good chance that the user will be seriously injured by the metal posts of the footrests.

En el documento US 4840390 se divulga una silla de ruedas con reposapiés del tipo anteriormente indicado. In US 4840390 a wheelchair with footrests of the type indicated above is disclosed.

Sorprendentemente, a pesar del riesgo conocido para el usuario, no se ha propuesto solución alguna en la técnica actual al problema anteriormente mencionado. Surprisingly, despite the known risk to the user, no solution has been proposed in the current technique to the aforementioned problem.

Por tanto, la intención de la presente invención es proveer un reposapiés para una silla de ruedas, en el que se evita el inconveniente mencionado de los reposapiés conocidos. Therefore, the intention of the present invention is to provide a footrest for a wheelchair, in which the aforementioned drawback of known footrests is avoided.

Compendio de la invención. Compendium of the invention.

Con este punto de vista, la presente invención concierne a un reposapiés según la reivindicación 1. With this view, the present invention concerns a footrest according to claim 1.

Las características importantes del dispositivo se definen en las reivindicaciones subordinadas. The important features of the device are defined in the dependent claims.

Con un reposapiés según la invención, la probabilidad de que el usuario resulte gravemente lesionado cuando impacta contra los reposapiés se reduce enormemente. De hecho, en este caso, cuando el usuario impacta con los reposapiés, los postes flexibles de dichos reposapiés están configurados para doblarse bajo el peso del usuario y, por tanto, evitar que el cuerpo del usuario sea perforado por dichos postes. With a footrest according to the invention, the probability that the user will be seriously injured when it hits the footrests is greatly reduced. In fact, in this case, when the user impacts with the footrests, the flexible posts of said footrests are configured to bend under the weight of the user and, therefore, prevent the user's body from being pierced by said posts.
