Abstract

The invention relates to a simple apparatus configured like a rod with wheels. The apparatus has been designed to be used by visually impaired people with the security that they will not stumble and to provide them with a high degree of freedom in their displacements without having to hold any heavy object nor make sudden zigzag movements as it is usually the case today.

ANTECEDENTES DE LA INVENCIÓN No son conocidos por el autor de esta invención, aparatos o dispositivos, ni siquiera parecidos, salvo el bastón tradicional, el plegable o el telescópico, que hasta ahora han sido para el invidente la mejor herramienta para caminar.BACKGROUND OF THE INVENTION Apparatus or devices, even similar ones, are not known by the author of this invention, except for the traditional cane, the folding or the telescopic, which until now have been for the blind the best tool for walking.
DESCRIPCIÓN DE LA INVENCIÓN La presente invención según queda reflejado en el enunciado de esta memoria descriptiva, se refiere a un aparato que, estando en movimiento, detecta y localiza cualquier obstáculo que el invidente encuentra a su paso, mediante la emisión de tonos acústicos, de manera que si el obstáculo esta a la derecha del invidente el aparato emitirá un tono, si esta al centro o a la izquierda, el tono que emita será diferente para cada uno, de manera que el invidente relaciona sonido con situación y actúa en consecuencia evitando el obstáculo que en el momento de sonar estará siempre a tres pasos de distancia.DESCRIPTION OF THE INVENTION The present invention as reflected in the statement of this specification, refers to an apparatus that, while on the move, detects and locates any obstacle that the blind person encounters in its path, through the emission of acoustic tones, of so that if the obstacle is to the right of the blind, the device will emit a tone, if it is in the center or to the left, the tone that it emits will be different for each one, so that the blind visually relates sound to situation and acts accordingly avoiding the obstacle that at the time of sounding will always be three steps away.
Los sonidos los puede percibir el invidente desde su lugar de emisión o a través de auriculares.The sounds can be perceived by the blind from their place of emission or through headphones.
El aparato que resulta de esta invención presenta el aspecto de un bastón con ruedas que en su parte delantera y a tres centímetros del suelo lleva un cabezal del que salen tres varillas dirigidas ala derecha, izquierda y centro que al contactar con cualquier obstáculo acciona alguno de los tres microrruptores que se alojan en el mencionado cabezal. El espacio que barre a lo ancho es el equivalente al cuerpo de una persona mas o menos sesenta centímetros. Para ayudar a una mejor comprensión de las características de este invento, acompañan a esta memoria cuatro dibujos, dos en perspectiva, uno en alzada y otro en perfil. BREVE COMENTARIO DE LOS DIBUJOS Las figuras 1 y 2 muestran en perspectiva caballera todas las piezas que constitiyen el aparato. Las figuras 3 y 4 muestran una vista en planta y en perfil del mismo. El aparato queda formado al ensamblar la parte inferior del bastón (3) con la parte superior del tubo (5) quedando como se aprecia en las figuras 3 y 4. DESCRD7CION TÉCNICAThe device that results from this invention has the appearance of a cane with wheels that in its front part and three centimeters from the ground has a head that leaves three rods directed to the right, left and center that when contacting with any obstacle triggers any of the three microswitches that are housed in said head. The space that sweeps across the width is the equivalent of a person's body about sixty centimeters. To aid in a better understanding of the characteristics of this invention, four drawings are attached to this report, two in perspective, one in elevation and one in profile. BRIEF COMMENTARY OF THE DRAWINGS Figures 1 and 2 show in a gentleman's perspective all the parts that constitute the apparatus. Figures 3 and 4 show a plan view and in profile thereof.

REIVINDICACIONES
Aparato en forma de bastón con ruedas capaz de transmitir al invidente sin necesidad de que suene, si cambia de terreno, si sube o si baja etc, mediante las vibraciones que percibe al tacto con la empuñadura. Se caracteriza porque al estar en movimiento detecta y localiza obstáculos a ras de suelo mediante la emisión de tonos acústicos que se producen por la estratégica colocación de tres varillas (9) orientadas a derecha, izquierda y centro, ubicadas en el cabezal (1) dispuesto en el extremo inferior del bastón y acoge en su interior tres microrruptores (8) accionados el contactar las varillas (9) con los posibles obstáculos. Los diferentes tonos acústicos se producen en el interior de la caja (4) ubicada cerca de la empuñadura por el dispositivo electrónico (12) y puede orse libremente o por auriculares.Apparatus in the form of a cane with wheels capable of transmitting to the blind person without the need for it to sound, if it changes terrain, if it rises or falls etc., by means of the vibrations that it perceives to the touch with the handle. It is characterized because being in motion detects and locates obstacles at ground level by emitting acoustic tones that are produced by the strategic placement of three rods (9) oriented to the right, left and center, located in the head (1) arranged at the lower end of the cane and inside it houses three microswitches (8) actuated by contacting the rods (9) with the possible obstacles. The different acoustic tones are produced inside the box (4) located near the handle by the electronic device (12) and can be freely or by headphones.
