Abstract

Perfeccionamientos en las tablas desarrollables para mostrar representaciones gráficas y similares, que presentan un medio de arrastre único accionable manualmente, unido cinemáticamente a dos elementos montados giratorios y susceptibles de estar unidos angularmente con, respectivamente, dos soportes rotativos dispuestos paralelamente el uno al otro, previstos para soportar cada uno el extremo arrollado de una banda de un soporte flexible que permite la escritura y/o la lectura efectuándose esta unión angular por medio de mecanismos que permiten el arrollamiento de la banda sobre uno cualquiera de los soportes rotativos y el desarrollamiento simultáneo de dicha banda, del otro soporte rotativo, manteniéndola al mismo tiempo tensada entre los dos soportes rotativos, caracterizados porque el medio de arrastre único está constituido por una unión flexible sin fin, que coopera simultáneamente con dos poleas unidas cada una cinemática y constantemente a uno de los dos elementos giratorios, siendo esta unión flexible sin fin accesible desde el exterior de la tabla desarrollable, para permitir su arrastrado manual, en uno cualquiera de los dos sentidos de desplazamiento.
