[0033] Embodiment 2

[0034] Next, Figure 5 It is a cross-sectional view of a main part of an elevator door apparatus according to Embodiment 2 of the present invention. In the figure, the engaging groove 10b is provided at the lower end of the side wall in the sill groove 10a. An upper groove 10c is provided on the upper surface (top surface) in the engaging groove 10b.

[0035] The front end portion of the engaging portion 13b of the hook fitting 13 is provided with a folded portion 13c bent upward at a right angle. The folded portion 13c protrudes upward from the front end of the engaging portion 13b and is inserted into the upper groove 10c. Then, when the door panel 4 is opened and closed, the folded portion 13c moves in the upper groove 10c. The other structure is the same as the first embodiment.

[0036] In such an elevator door device, since the upper groove 10c is provided in the engaging groove 10b, and the turning part 13c is provided on the hook fitting 13, it is po...

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] ...
