Abstract
Dispositivo perfeccionado de obturación de un orificio, en el interior de un recinto, provisto de un orificio de acceso, de sección inferior a la sección del orificio que debe obturarse, que comprende una tapa en varias partes, y una superficie de apoyo de la tapa, dispuesta en el recinto, sobre el contorno del orificio, caracterizado por el hecho de que la tapa se compone de un elemento central, y de dos elementos laterales en forma de C, cuyas dimensiones permiten el paso por el orificio de acceso, comprendiendo cada elemento lateral, a ambos lados de una escotadura, dos brazos, articulados en sus extremos sobre los brazos correspondientes del otro elemento lateral, alrededor de dos charnelas, cuyos ejes están alineados, estando replegados los dos elementos laterales uno sobre el otro para el paso por el orificio de acceso, y abiertos para aplicarse sobre la superficie de apoyo, recubriendo cada elemento una parte de la citada superficie de apoyo, a ambos lados del eje de articulación delas charnelas, recubriendo el elemento central la abertura formada por las dos escotaduras contiguas, y garantizando la rigidización el conjunto.
