Abstract

The invention provides an elevator door device which prevents a horizontally movable door plate from dropping owing to an outside force by means of a simple structure. A locking slot (10b) is arranged on a side wall in a sill slot (10a). A hook fitting (13) with an L-shaped section is installed on the lower end portion of the door plate (4). The hook fitting (13) is locked with the locking slot (10b) so as to limit the door plate (4) to move upwards. The hook fitting (13) has a vertical installing portion (13a) and a locking portion (13b) which is produced by bending the lower end portion of the installing portion (13a) to a right angle. The locking portion (13b) is horizontally projected from the installing portion (13a) and is inserted into the locking slot (10b).

Description

technical field [0001] The invention relates to a door arrangement for an elevator with horizontally moving door panels. Background technique [0002] In a conventional door device for an elevator, a doorway is opened and closed by moving an upper door and a lower door in an up and down direction. The upper door and the lower door move along door rails provided on both sides of the entrance. And, on both sides of the entrance and exit, the cross-section is U-shaped receiving fittings, and the two ends of the width direction of the lower door are equipped with stepped hooking fittings, and the front end of the hooking fittings is inserted into the receiving fittings. Furthermore, when the lower door is deformed by an external force from the boarding point side, the hook fitting and the storage fitting are engaged to prevent the lower door from falling off (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 61-69682 [0004] ...
