OBJETO DE LA INVENCIONOBJECT OF THE INVENTION

La invencion, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una contera flexible, la cual aporta varias ventajas e innovadoras caracteristicas inherentes a su particular configuracion, que se describiran con detalle mas adelante y que suponen una destacable mejora del estado actual de la tecnica.The invention, as expressed in the statement of the present specification, refers to a flexible account, which provides several advantages and innovative features inherent to its particular configuration, which will be described in detail below and which represent a remarkable improvement of the state. Current technique.

El objeto de la presente invencion se centra concretamente en una contera destinada a incorporarse en el extremo inferior de muletas, bastones u otros aparatos ortopedicos de apoyo para evitar deslizamientos indeseados, la cual, constituida por una pieza de caucho o material similar, presenta la innovadora particularidad de contar con una configuracion estructural que comprende un fuelle que la dota de cierta flexibilidad entre su parte superior y su base, lo cual permite un mejorado agarre de la superficie inferior de la misma al piso, a la vez que evita su deterioro por deformaciones y esfuerzos recibidos por la inclinacion del tubo o vara del util en que se incorpora.The object of the present invention focuses specifically on a bead intended to be incorporated in the lower end of crutches, canes or other orthopedic support devices to avoid unwanted landslides, which, constituted by a piece of rubber or similar material, presents the innovative particularity of having a structural configuration that includes a bellows that gives it some flexibility between its upper part and its base, which allows an improved grip of the lower surface of the same to the floor, while preventing its deterioration due to deformations and efforts received by the inclination of the tube or rod of the tool in which it is incorporated.

ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION

El problema tecnico que plantean las conteras existentes, aplicables para muletas, bastones, andadores y otros aparatos de apoyo, suele ser una falta de adherencia adecuada y, sobre todo, un rapido deterioro del material con que estan fabricadas ya que, dicho material, al ser caucho o similar para propiciar el agarre en superficies lisas, suele ser un material que se desgasta y se rompe o se agrieta por el uso.The technical problem posed by existing containers, applicable for crutches, canes, walkers and other support devices, is usually a lack of adequate adhesion and, above all, a rapid deterioration of the material with which they are manufactured since, said material, at be rubber or similar to promote the grip on smooth surfaces, it is usually a material that wears and breaks or cracks from use.

Ademas, uno de los principales efectos que provocan el desgaste y deterioro de las conteras es la constante existencia de la fuerza oblicua que se ejerce sobre las mismas, ya que tanto en muletas como en bastones suelen utilizarse apoyando el tubo o la vara que los conforma con cierta inclinacion y raramente en una posicion totalmente vertical. Ello provoca, asimismo, que la superficie inferior de la contera solo haga contacto con el suelo en una porcion de la misma y no en toda su superficie, con lo cual el agarre que se produce tambien queda reducido.In addition, one of the main effects that cause wear and deterioration of the beams is the constant existence of the oblique force exerted on them, since both crutches and canes are usually used to support the tube or the rod that forms them with some inclination and rarely in a completely vertical position. This also causes the bottom surface of the container only to make contact with the ground in a portion thereof and not in its entire surface, whereby the grip that is produced is also reduced.

Para mejorar este agarre existen algunas soluciones, como por ejemplo la que describe el documento ES1048407U, en el que se reivindica una contera que, entre otras particularidades, presenta una forma troncoconica en su parte superior, de mucho menor diametro que la base, permitiendo que dicha parte superior troncoconica, gracias a la flexibilidad del material, se incline con respecto al eje vertical central de la base por la accion del propio usuario sobre el baston o por cualquier diferencia en la nivelacion del piso, mientras que la base permanece apoyada sobre el piso en su totalidad.To improve this grip there are some solutions, such as the one described in document ES1048407U, in which a container is claimed that, among other features, has a truncated conical shape at its top, much smaller in diameter than the base, allowing said upper trunk, thanks to the flexibility of the material, is inclined with respect to the central vertical axis of the base by the user's own action on the cane or by any difference in the leveling of the floor, while the base remains supported on the floor in its entirety.

Dicha solucion, sin embargo, presenta ciertos aspectos susceptibles de ser mejorados, en particular por el hecho de que la flexibilidad que se consigue se debe principalmente al tipo de material, pero en cualquier caso supone un angulo de movimiento muy reducido que, ademas, con el tiempo causa deterioro en la pieza debido a los esfuerzos recibidos.This solution, however, presents certain aspects that can be improved, in particular by the fact that the flexibility achieved is mainly due to the type of material, but in any case it implies a very small angle of movement that, in addition, with time causes deterioration in the piece due to the efforts received.

El objetivo de la presente invention es, pues, desarrollar un nuevo tipo de contera que permita dotarla de mayor flexibilidad y permita el contacto completo de la superficie inferior del mismo sobre el piso independientemente de la inclination que sufra la muleta, baston o util de que se trate, debiendo senalarse que, al menos por parte del solicitante, y en referencia al estado actual de la tecnica, se desconoce la existencia de ninguna otra contera que presente unas caracterlsticas tecnicas, estructurales y constitutivas semejantes a las que presenta la que aqul se reivindica.The objective of the present invention is, therefore, to develop a new type of bead that allows it to be more flexible and allows full contact of the lower surface thereof on the floor regardless of the inclination suffered by the crutch, baton or tool that It should be noted that, at least on the part of the applicant, and in reference to the current state of the art, the existence of any other type that presents technical, structural and constitutive characteristics similar to those presented here is unknown. vindicate
