Abstract

Esfera diurno/nocturna estacional. Consta de un globo terrestre (1) que, al girar inscrito en una esfera trasparente compuesta por dos semiesferas (2,3) de diferente coloración que a su vez oscilan con un recorrido de 46 grados con 54 minutos de arco,simula la sucesión noche/día y el proceso de las estaciones. La citada oscilación es facilitada por dos ranuras (4,5) de 23 grados con 27 minutos de arco practicadas en cada una de las semiesferas (2,3). Dichas ranuras (4,5) son atravesadas por las prolongaciones (6) del eje polar del globo terrestre (1). Tiene aplicaciones didácticas e industriales. Se prevén versiones con la incorporación de una esfera celeste circunscrita, con la utilización de una sola de las semiesferas y con la modificación del sistema de anclaje de la esfera trasparente al bastidor de sustentación. Se prevén todas las versiones con iluminación interior.
