Abstract

PROBLEM TO BE SOLVED: To provide an elevator doorway device which enables the sills of the doorways of an elevator landing and an elevator car to be standardized, and which can inhibit extraneous matter from entering the sill groove of a door closable only to around the center of the doorway.SOLUTION: The sill grooves of sills which slidingly guide the door shoes of a first door which moves to the closed-side end face of a doorway and a second door which moves to around the center of the doorway are formed from the open-side end face of the doorway to the closed-side end face thereof. In a state where the second door is located in a closed position to around the center of the doorway, the sill groove for the second door between the second door and the closed-side end face of the doorway is closed with a closing body. Thereby, the cross-sectional shapes of the sills can be made uniform regardless of the width dimensions of doorways, enabling the standardization of the sills. In addition, since there is the closing body in the sill groove of the sill between the second door in a closed state and the closed-side end face of the doorway, extraneous matter can be inhibited from entering the sill groove.

Description

  The present invention relates to an elevator entrance / exit device that opens and closes a door provided in an elevator hall or a door provided in an elevator car.

  Doors for passengers to enter and exit are provided at the entrance of the elevator car and the entrance of the elevator platform. In general, these doors are installed by overlapping two doors, and when closing the door, move one door until it contacts the closing end face of the doorway, and move the other door to a half position to move the doorway. It is trying to block. And when opening a door, one door and the other door are moved to the opening side end surface of an entrance / exit, and the entrance / exit is fully opened so that one door and the other door may mutually overlap in this state.

  And one of these doors and the other door is provided with a door shoe at the lower end, and this door shoe can slide in the sill groove of the sill installed on the floor of the elevator platform or elevator car Is engaged. However, foreign objects such as dust and pebbles are likely to enter the sill groove provided in this sill, and if the slab is mixed with pebbles etc. and moves to the sliding area of the door shoe, it will hinder the door opening and closing operation. There is. Furthermore, it is conceivable that the wheel of the carriage carrying the luggage is fitted into the sill groove and the carriage cannot be moved.

  Here, the sill groove of the sill needs two sill grooves for one door and the other door, but the sill groove for one door does not move because one door moves to the closing side end face of the doorway I can't do it. In addition, when the door is fully closed, one sill groove is closed by the door, so it is difficult for foreign matter to mix in, and the other door can only slide near the center of the doorway, so It is an environment in which foreign matter is easily mixed into the sill groove.

  From such a point of view, it has been proposed to eliminate the sill groove of the sill as much as possible to reduce the mixing of foreign substances. For example, in Japanese Patent Application Laid-Open No. 08-12235 (Patent Document 1), a door sill (including a sill groove) is formed in the middle of an entrance (about half) of two doors, and beyond. Proposes a threshold that eliminates the threshold itself. According to this, since there is no sill itself other than the sill used by the front door, there is no sill groove, and pebbles and garbage are not mixed into the sill groove.

Japanese Patent Application Laid-Open No. 08-12235

  By the way, this type of elevator platform and elevator car have different entrance dimensions, especially lateral dimensions, depending on the elevator specifications (passenger load capacity, etc.), and there are many sills at these entrances according to the lateral dimensions. It is necessary to prepare these types of thresholds, and the standardization of thresholds is required.

  However, in the sill where the door sill (including the sill groove) is formed in the middle of the doorway (about half) as in the above-mentioned Patent Document 1, the sill after the sill itself is removed, the side of the doorway It is necessary to prepare many thresholds according to the dimensions. For this reason, there is a problem that the threshold cannot be shared and the product price increases, and the supply and demand management of the product (a management system that can be supplied immediately when necessary) is complicated.

  An object of the present invention is to provide a common entrance / exit sill for an elevator and an elevator cab, and to prevent entry of foreign matter into a door sill groove that closes only near the center of the entrance / exit. To provide an apparatus.

  A feature of the present invention is that the sill groove of the sill that slides and guides the door shoe of the first door that moves to the closing end face of the entrance and the second door that moves to the vicinity of the center of the entrance is closed from the opening end face of the entrance. Formed over the side end face, with the second door in the closed position up to the vicinity of the center of the entrance / exit, closing the second door sill groove between the second door and the exit end face of the entrance / exit It was in the place where it was made to close with.

  According to the present invention, the cross-sectional shape of the sill can be unified regardless of the width dimension of the doorway, so that the sill can be shared, and between the second door in the closed state and the closed side end surface of the doorway. Since the sill groove of the sill has a blocking body, it is possible to prevent foreign matter from entering the sill groove.
