JIG FOR CONNETING A ELEVATOR DOOR INTO DOOR GUIDE SEAL}

The present invention relates to a door guide for preventing elevator landing door departure, more specifically, the door departure between the landing door and the landing door guide in order to prevent the departure of the door by the impact or pressure from the outside during opening and closing operation of the landing door. It relates to an elevator platform door departure preventing jig for connecting the door shoe to the door guide without replacing the installed door guide in connecting the prevention door shoe.

For reference, the door described below means a door installed in the boarding point, the door guide means that the door is installed on the floor, it means to guide the door for smooth opening and closing of the door during the opening and closing operation of the door.

As is well known, elevators (hereinafter referred to as "elevators") are convenient facilities for moving users entering and leaving a high-rise building to a high floor, and have been commonly installed in high-rise buildings or buildings for decades.

Elevators can be said to be a device that emphasizes safety because they elevate people, but large and small accidents frequently occur in old elevators installed long time ago.

One of the problems that need to be improved in the old type of elevator is that when external force or impact is applied to the front of the landing door, the landing door is pushed toward the elevator passage by moving away from the opening and closing path and falling down into the elevator passage. .

The main cause of such an accident is when the door shoe connecting the door and the door guide which is frequently opened and closed is worn and loosened on the door shoe and the door guide, and a separate door departure prevention device between the door and the door guide. B. It occurs mainly in older elevators without connecting devices.

To solve this problem, various solutions have been proposed, and examples of the proposed technology are disclosed in Korean Patent Application Publication No. 10-2011-0083986, "Elevator Platform Doors Complementing the Breakaway-proof Structure," Patent Registration No. 10-0898507 "Screen door of elevator platform equipped with foreign substance discharge device and foreign substance discharge device", Publication No. 10-2010-0124470 "Elevation prevention device for elevator platform door" and Patent Publication No. 10-2010-0101411 "Elevator platform door Release prevention devices, "etc., may be referred to.

Various elevator landing door departure prevention techniques as described above are helpful to prevent the door from leaving the track, but in the case of the old elevator model installed long time, it is difficult to incorporate the elevator landing door departure prevention device due to the structural defect of the door guide. Essentially there is a problem that must be replaced with a new door guide.

However, replacing with a new door guide may be the most effective solution to fundamentally prevent the door from falling out, but it is costly, and the operation noise of the replacement of the door guide and the operation of the elevator during the replacement work period Since it must be stopped, there is a disadvantage that a user, such as a patient, a pregnant woman or an elderly person, becomes very uncomfortable in entering and leaving a building.

This inconvenience is a matter of course for people to avoid falling accidents, but in reality, apartments like apartments require many people to deal with the inconvenience, so the choice of residents who need to install a new door guide does not match. Not simple

Therefore, the approach to reinforce the door departure prevention function using the existing door guide can be said to have a very useful advantage.

Patent Publication No. 10-2010-0101411 of the various conventional door departure prevention device technology cited above may be a good example of incorporating the door departure prevention device using a door guide.

In conclusion, however, the technique of the above-mentioned Patent Publication No. 10-2010-0101411 actually has a structural defect that is difficult to employ in the field.
