Abstract
Bisagra perfeccionada, que presenta un eje de giro introducido en el recinto interior de una sucesión de anillos, terna tivomente correspondientes a una y otra parte de la bisagra, terminando los anillos extremos en sendos tapones roscados y estando eventualmente el eje firmemente asociado a uno o más anillos de paridad distinta a los que llevan dichos tapones, caracterizada porque los repetidos tapones aplican contra los extremos del eje de giro sendos casquillos, produciéndose entre éstos y el eje zonas de apoyo puntual, para lo cual dicho eje termina en sendas puntas cónicas
