MULETA.CRUTCH.
Objeto de Ia invenciónObject of the invention
La presente invención se refiere a una muleta, del tipo de las usadas como apoyo por personas que presentan una cierta dificultad para andar y requieren un útil de apoyo para desplazarse con más seguridad.The present invention relates to a crutch, of the type used as support by people who have a certain difficulty in walking and require a support tool to move more safely.
Antecedentes de Ia invención.Background of the invention.
En Ia actualidad existen una gran variedad de muletas y utensilios de ortopedia destinados a que las personas que presentan una cierta dificultad para andar puedan desplazarse con mayor soltura y seguridad. Estas muletas están constituidas principalmente por un elemento tubular de longitud regulable y que presenta en su zona media superior unos medios para el apoyo y/o agarre del usuario, tal como un asidero y una horquilla de sujeción al antebrazo o una barra transversal para apoyar Ia axila. La muleta permite así que el usuario pueda apoyarse en el suelo manteniendo su posición erguida, de forma similar a Ia realizaría si se apoyara en un pasamanos o similar. El usuario, a medida que avanza en su camino, necesita levantar Ia muleta para colocarla en una posición más avanzada y después caminar él un paso. Este movimiento repetitivo provoca que el usuario se mueva "a saltos" y que el peso de la muleta pueda repercutir en el cansancio del usuario, por ejemplo personas de edad mayor o muy debilitadas.At present there are a wide variety of crutches and orthopedic tools intended for people who have a certain difficulty walking can move more easily and safely. These crutches are mainly constituted by a tubular element of adjustable length and which has in its upper middle area means for the support and / or grip of the user, such as a handle and a fork for securing the forearm or a crossbar to support the armpit. The crutch thus allows the user to lean on the ground while maintaining its upright position, similar to what it would do if it were supported by a handrail or similar. The user, as he progresses on his way, needs to lift the crutch to place it in a more advanced position and then walk it one step. This repetitive movement causes the user to move "in leaps" and that the weight of the crutch can have an effect on the user's fatigue, for example elderly or very weakened people.
Descripción de Ia invenciónDescription of the invention
La muleta de esta invención presenta unas particularidades técnicas destinadas a mejorar Ia comodidad de uso y su estabilidad.The crutch of this invention has technical peculiarities intended to improve the comfort of use and its stability.
En efecto, el elemento tubular de Ia muleta presenta en su extremo inferior una rueda de apoyo, de giro libre y provista de unos medios de bloqueo. A su vez, en Ia zona intermedia del elemento tubular se encuentra un caequillo giratorio, pero que no se puede desplazar axialmente, sobre el que se encuentra articulado un brazo auxiliar. Este brazo está provisto de una rueda inferior de apoyo sobre el suelo y está posibilitado de abatimiento entre una posición operativa en Ia que forma ángulo con Ia parte inferior del elemento tubular y una posición inoperante en Ia que se dispone sensiblemente paralelo a dicho elemento tubular.In fact, the tubular element of the crutch has at its lower end a support wheel, of free rotation and provided with locking means. In turn, in the intermediate zone of the tubular element is a bushing rotating, but which cannot be moved axially, on which an auxiliary arm is articulated. This arm is provided with a lower support wheel on the ground and is capable of folding between an operative position in which it forms an angle with the lower part of the tubular element and an inoperative position in which it is disposed substantially parallel to said tubular element.
De esta forma se consiguen dos efectos beneficiosos consistentes en que el usuario no necesita levantar Ia muleta para desplazarla en su caminar y que el apoyo de Ia muleta en el suelo es notoriamente más estable. La rueda del extremo del elemento tubular permite que el extremo de Ia muleta no se tenga que levantar, por Io que el usuario no carga con Ia muleta para su posicionado a medida que anda. En el caso de que el usuario necesite apoyarse de una forma inamovible en el extremo inferior de Ia muleta, por ejemplo para subir una escalera, los medios de bloqueo evitan el giro de Ia rueda anterior y que Ia muleta pueda resbalar de Ia posición de apoyo.In this way, two beneficial effects are achieved, consisting in the fact that the user does not need to lift the crutch to move it while walking and that the support of the crutch on the ground is notoriously more stable. The wheel of the end of the tubular element allows that the end of the crutch does not have to be lifted, so that the user does not load with the crutch for positioning as he walks. In the event that the user needs to rest in an immovable way on the lower end of the crutch, for example to climb a ladder, the blocking means prevent the rotation of the previous wheel and that the crutch can slide from the support position .
El apoyo simultáneo en Ia rueda anterior y Ia rueda posterior presente en el extremo del brazo auxiliar, permite que el peso o carga que ejerce el usuario al apoyarse en Ia muleta se distribuya entre ambos puntos, con Io que Ia muleta es más estable que una muleta convencional que puede pivotar sobre su único punto de apoyo y bascular si el apoyo del usuario se ha realizado de forma inadecuada. La rueda posterior sigue a Ia anterior a medida que el usuario camina en una dirección determinada. Además como el elemento tubular principal y el casquillo al que se encuentra acoplado el brazo posterior pueden girar entre sí, se posibilita Ia dirección de avance de Ia muleta al andar el usuario. Así es, cuando el usuario dispone Ia muleta levemente girada a un lado o al otro, Ia rueda del extremo del elemento tubular avanza en una dirección oblicua a Ia dirección en Ia que está dispuesta Ia rueda del brazo auxiliar. Esta disposición oblicua hace que el avance de rodadura de Ia muleta sea trazando una curva o arco más o menos amplia. Los medios de bloqueo de Ia rueda están compuestos principalmente por una leva giratoria provista de un pedal para su accionamiento entre las posiciones de bloqueo y liberación de .Ia rueda. De esta forma el usuario puede bloquear y desbloquear Ia rueda con comodidad y sin necesidad de agacharse.The simultaneous support on the front wheel and the rear wheel present on the end of the auxiliary arm, allows the weight or load exerted by the user when resting on the crutch to be distributed between both points, so that the crutch is more stable than a Conventional crutch that can pivot on its single point of support and swing if the user's support has been improperly performed. The rear wheel follows the previous one as the user walks in a certain direction. In addition, since the main tubular element and the bushing to which the rear arm is attached can rotate with each other, the forward direction of the crutch is possible when the user is walking. That is, when the user has the crutch slightly turned on one side or the other, the wheel of the end of the tubular element advances in an oblique direction to the direction in which the auxiliary arm wheel is arranged. This oblique arrangement causes the rolling progress of the crutch to be tracing a more or less wide curve or arc. The locking means of the wheel are mainly composed of a rotating cam provided with a pedal for actuation between the lock and release positions of the wheel. In this way the user can lock and unlock the wheel comfortably and without having to bend down.
El brazo auxiliar comprende en la zona de articulación un tope escamoteable que es acoplable en unos orificios del casquillo giratorio para su fijación en cualquier de las posiciones operativa e inoperante. De esta forma el brazo auxiliar se encuentra siempre bajo control y no se puede plegar o desplegar accidentalmente, sino que se dispone paralelo al elemento tubular para su disposición inoperativa sin estorbar, o se encuentra extendido, formando un ángulo adecuado para su uso.The auxiliary arm comprises in the articulation zone a retractable stop which is attachable in holes of the rotating bush for its fixation in any of the operative and inoperative positions. In this way, the auxiliary arm is always under control and cannot be accidentally folded or unfolded, but is arranged parallel to the tubular element for inoperative arrangement without being hindered, or is extended, forming an angle suitable for use.
Se ha previsto que el elemento tubular de Ia muleta presente en una zona intermedia unos ganchos laterales para el colgado de objetos diversos, tales como bolsas, carpetas o maletines ligeros, que llevados a mano pueden dificultar Ia movilidad del usuario.It is envisioned that the tubular element of the crutch present in an intermediate zone some side hooks for hanging various objects, such as bags, folders or light cases, which carried by hand can hinder the user's mobility.
