PERFECCIONAMIENTOS EN PUERTAS DE CORREDERA

摘要

A sliding door arrangement which provides lateral support for the free edge or bottom nose corner of a door comprises a retractable member which is raised through an aperture in the floor or doorway threshold to interlockingly engage said edge of the door in the closed position. When the door is opened the engaging member is automatically retracted to lie flush with the floor surface. The member is carried by a rocking lever under the floor which is linked to another counter-balanced lever nearer the door frame which also has a raised protrusion which is abutted by a cam on the door as it reaches the closed position.
