Embodiment 1

[0022] Figure 1 to Figure 4 Embodiment 1 of the elevator apparatus of this invention is shown.

[0023] As shown in the figure, the elevator apparatus of the present invention includes: the car doors 1a, 1b which are operated in opposite directions to open and close the entrance and exit of the car; The car floor sill 2 guides the movement of the car doors 1a, 1b. The car doors 1a, 1b move horizontally along the car sill 2 by the driving force of a door motor (not shown).

[0024] In addition, in this embodiment, a double-door type elevator apparatus is taken as an example, but of course, it is also applicable to a single-door type elevator apparatus in which the doors are opened and closed in one direction.

[0025] In addition, the car sill 2 is provided with a sill groove 3 extending along the front width direction of the car doorway, and door shoes 4a, 4b, 4c installed at the lower ends of the car doors 1a, 1b are inserted into the sill grooves. The cam groove 3 guides ...

Abstract

The invention provides an elevator device which can seal the gap formed under a door sleeve when a car door closes. The elevator device is provided with a sealing plate airtight member (10a, 10b) installed on a sealing plate (6a) extending along the heightwise direction of a door opening side end portion of a car door (1a). When the car door closes, at least a part butts against a door opening side end surface of a door lower airtight member (5a) in the gap between the lower end part of the sealing car door (1a) and a car sill (2), and another part butts against the side part of a car column (11) forming a part of an entrance / exit of a car, so that the gap under the car sleeve is sealed. And a sill notch (12) is formed in the car sill (2). When the car door (1a) opens, the sealing plate airtight member (10a) can be moved to a position lower than a sill surface (2a) of the car sill (2).

Description

technical field [0001] The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus suitably applied to a structure having a door main body for opening and closing the entrance and exit of a car. Background technique [0002] In general, an elevator apparatus requiring airtightness is provided with a lower door gas seal that seals the gap between the lower end of the car door and the car sill when the car door is closed. Patent Document 1 discloses a device having an interlocking mechanism that maintains a non-contact state between the lower door air seal and the car sill during the opening operation of the car door, and maintains the opening and closing performance of the car door. [0003] In addition, Patent Document 2 discloses an elevator apparatus having the above-mentioned door lower air seal, in which a sealing member is provided in the car sill, and when the car door is in the closed state, the end surface of the door lower ...
