[0001] APPARATUS FOR PREVENTING DERAILMENT OF ELEVATOR DOOR [0002]

The present invention relates to an elevator door departure prevention apparatus, and more particularly,

The present invention relates to an elevator door detachment prevention device capable of more effectively preventing a detachment of a door due to an external impact while preventing a door from being shaken at the time of door opening and closing and safely opening and closing the door.

An elevator generally refers to a device for moving a person, an animal, or an object up and down, that is, vertically up and down, in a building, apartment, department store, ship or the like.

 The elevator device includes an elevator car that moves a passenger while moving along a hoistway formed in a vertical direction inside a building with a passenger on the inside, a motor unit, a hoisting machine, a rope, a pulley, And an elevator control unit for controlling the mechanical unit according to the button operation of the passenger so that the elevator car is driven to the corresponding floor.

Particularly, the structure of the door portion of the elevator is divided into a landing door installed on the building side and a car door installed inside the elevator car. The lift doors of the elevator are constituted by symmetrical left and right pairs and are configured to be opened or closed with each other on both sides.

In order to ensure the safety of the elevator apparatus, an interlock device is installed at the upper part of the platform door, and a door separation prevention device is installed at the lower part of the platform door.

Particularly, the door separation prevention device is installed to prevent a safety accident of a passenger by preventing the separation door from being separated even if an external pressure or shock is applied.

The structure of the conventional door departure prevention apparatus will be briefly described.

And a shoe which is inserted into the guide space portion of the chamber and fixed to the door by a fixing bolt or the like and has a structure in which the shoe is slidably guided into the guide space portion of the chamber according to the operation of the door.

However, such a structure has the problem that the door is depressed, warped and deformed due to an external impact, so that it moves to the upper portion of the guide space portion of the thread and is disengaged, and both sides of the shoe are worn by the continuous opening / closing operation of the door, So that the door and the shoe are easily coupled to each other due to the external impact. As a result, the door easily escapes and safety accidents occur frequently.

Registration room 20-0322281 "Door shoe for door of elevator door and structure preventing escape from door.

According to an aspect of the present invention, there is provided an airbag device comprising: an airbag section having elasticity applied on both sides thereof; The door can be prevented from being shaken by an external impact and the latching portion can be formed on the bottom surface of the detachment preventing member and the latching portion can be caught by the latching portion of the seal, Which is capable of completely preventing the door from being detached due to the elevation of the door.

In order to achieve the above object,

An elevator door detachment prevention device installed on a floor of an elevator landing platform to prevent the door from escaping,

The separation preventing device includes a body which is fixedly connected to a fixing bracket of a door, a separation preventing member including a bending portion formed at a lower end of the body, a guide space formed for inserting a lower portion of the separation preventing member, And a door seal which is further provided with a fixing part formed on one side of the guide space part to prevent the detachment of the door from the detachment of the detachment prevention part, wherein the body of the detachment prevention member is formed with two space parts, And a first contact piece and a second contact piece which are connected to each other and formed to be bent.
