STRUCTURE FOR PREVENTING DEVIATION OF ELEVATOR DOORS AND INSERTION OF FOREIGN OBJECTS

WIPO Patent Application WO/2010/032972

A2

The present invention relates to a structure for preventing: deviation of elevator doors, elevator doors from being opened by external applied forces, accidents caused by opening of elevator doors and foreign objects being inserted into the rail groove. The present invention comprises a left door (LD) and a right door (RD) each of which is provided with a shoe (100) arranged below the left and right doors, and a seal (200) having a rail groove (210) for inserting shoe (100). Both the left door (LD) and the right door (RD) have a bottom with a stopper bracket (2). The rail groove (210) has an inner wall with a stopper groove (212) for inserting a front end (21) of a horizontal part of the stopper bracket (2). The stopper bracket (2) is a rectangular metal plate attached to the bottoms of the left and right doors (LD, RD). The stopper bracket (2) is formed by bending a part of each of the bottoms of the left and right doors (LD, RD) in one direction to have a cross section of an inverse L-shape. The stopper bracket (2) has an intermediate bent portion (24) formed by double-bending the intermediate portion of the stopper bracket in both the horizontal and vertical directions. An elongated hole (20) having a predetermined length is formed below the intermediate bent portion (24).
