Abstract
Dispositivo de representación en relieve que abarca, una serie de transductores electromecánicos, incluyendo cada uno de ellos por lo menos una lámina, piezoeléctrica bi- morfa inclinable en torno a un eje perpendicular al eje longitudinal de la lámina con la aplicación de un voltaje de corriente continua, medio de apoyo para al menos un extremo de la mencionada lámina, una varilla acolada al medio de acoplamiento mencionado y medio para aplicar un voltaje de corriente continua a la mencionada lámina, por lo que con la aplicación del mencionado voltaje de la curvatura de la lámina causa un desplazamiento estático de la mencionada varilla en el sentido de su eje propio longitudinal, que se caracteriza por el hecho de que cada uno de los extremos de cada una de las varillas está provisto de medio de apoyo, las varillas están dispuestas transversalmente a lámina piezoeléctricas y el mencionado medio de acoplamiento de las varillas con las láminas piezoeléctricas comprende una tablilla generalmente rectangular, de material aislante, definiendo la mencionada tablilla una serie de orificios que atraviesan la tablilla perpendicularmente a su superficie mayor, estando uno de los mencionados orificios roscado para engranar una rosca correspondiente formada sobre una de las mencionadas varillas, siendo el resto de los mencionados orificios libremente atravesable por las otras varillas, y una ranura que comunica el orificio roscado con una de las superficies menores de la tablilla, de tal manera que proporciona un efecto de sujeción de la periferia del orificio roscado sobre la varilla roscada.
