Description

[0001] Emergency Opening Apparatus of Elevators [0002]

The present invention relates to an emergency opening device for an elevator, and more particularly to an emergency opening device for an elevator in which an elevator door can be opened by a passenger in an emergency situation in which the operation of the elevator is interrupted by failure and power cut-off.

Generally, an elevator is a cage which moves up and down along a hoistway of a predetermined space vertically formed in a building, and is used for transporting a passenger or a cargo.

The elevator installed floors on each floor of the building, which is a waiting place for the carriage of the cage, and platform doors for the passengers to safely wait on the boundary between the floor and the hoistway.

When the cage moves to the correct position of the floor, the door installed on the cage is automatically opened, so that the door installed on the platform is also opened to allow the passenger to board or get off the cage. The door is automatically closed, the door installed on the platform is interlocked and closed, and the hoistway and the floor are separated into independent spaces.

However, although these elevators are aimed at safe operation, emergency situations such as power failure due to abnormal power supply or elapse of facilities due to long-term use, and electronic errors cause occasional emergency situations other than normal operation, The passenger must be opened manually by opening a door provided on an appropriate floor to rescue the passenger.

In the conventional manual opening / closing apparatus for manually opening the door in an emergency, a key groove horizontally penetrating the front upper portion of the door is formed, and an operation port vertically installed at the rear of the door is vertically installed. On one side of a plate formed on the upper part of the door so that the other side of the flow latch can be hooked or released by rotation so that the door can be closed or opened. The fixed base is firmly and integrally installed.

The operation of the conventional manual opening / closing device is such that when the cage is stopped at an abnormal position in an emergency, a rod-shaped operation key having a predetermined diameter and a length is inserted into the keyway, one end of the operation key is positioned below the operation opening, And the operating hook is pushed up to the upper side, the flow latch which is in contact with the upper end of the operating pivot rotates about the rotary shaft fixing one side, and the other side of the flow latch is released from the fixed base provided on the panel to open the door .

However, in order to open the landing door by using such a manual opening / closing device, the operation point, that is, the operation key is inserted into the key groove, the lower end of the operation groove and the end of the operation key must be in contact with each other. However, Even a skilled worker can not perform a quick lifesaving because it takes a long time to open the door, and since the panel and the operation opening must be installed close to each other, a heavy noise may be generated due to vibration and trembling when the cage is operated.

Further, since the operation keys are provided in various forms according to the maker of the elevator and installation of the operation tool, they are difficult to open the door if the operator does not know the shape of the operation key.

In addition, a forced elevator opening / closing device such as a hydraulic jack key used by an emergency exit door such as a fire station has a problem that a door is forced to open, thereby causing breakage such as door collapse
