Abstract
Un escalon provisto de superficies reflectoras capaz de evitar que superficies reflectoras de colores diferentes se conecten de manera erronea al escalon,que asegura la unidad de las posiciones de los escalones respecto de los colores derecho eizqui erdo de los mismos sin necesidad de fijar el escalon nuevamente contra el cuerpo, que sirve de manera suficiente como marcacion de canal, y que se puede utilizar por un período prolongado de tiempo dado que determinados colores están provistosen posic iones determinadas aun si el escalon está fijado al cuerpo en tanto las partes anterior y posterior estáninvertidas. El escalon provisto de superficies reflectoras incluye una superficie de apoyo y porciones laterales contínuas yposicionadas a ambos lados de lasuperficie de apoyo, donde el escalon comprende además un conjunto de miembros de superficies reflectoras compuesto de superficies reflectoras superior einferior que tienen cada una de ellas forma de codo vistos desdela parte superior de los mismos y son de colores diferentes, una porcion convexa que se forma en la superficie posterior de una superficie reflectora de un color en tanto se forma una porcion concava en la superficie posterior de otra superficiereflectora de otro color, una porcion concava y una porcion convexa que se forman en el escalon correspondiente a la porcion convexa y a la porcion concava decada reflector, las superficies reflectoras respectivas están retenidas por el escalon demanera tal de cubrir las superficies superior e inferior y las superficies anterior y posterior de la superficie de apoyo y las porciones laterales con los miembros de superficies reflectoras respectivos en ambos ángulos formados entre la superficiede apoyo y las porciones laterales, y el color de la superficie reflectora superior en un ángulo es igual al de la superficie reflectora inferior en el otro ángulo.
