Description

An apparatus for falling prevent of elevator

The present invention relates to an apparatus for preventing a fall of an elevator, and more particularly, to an apparatus that can prevent a fall when a user enters unconsciously and opens a door without an elevator car due to a malfunction of the elevator. will be.

Generally, elevators are installed in high-rise buildings and used as a means of transporting people or objects upstairs or downstairs.

Such a lifter moves the elevator car up or down by automatic control, and when the door is opened, the elevator car is moved to a desired position.

However, such elevators sometimes have doors open even when there is no elevator car due to a malfunction, and the user frequently enters the elevator unconsciously and falls down frequently, causing injury.

Alternatively, the operator may fall down while stepping on the foot while performing maintenance or inspection work inside the elevator.

In view of the above problems there has been disclosed a fall prevention device of the elevator. Registered Utility Model No. 195076 (Safety device for construction elevators) (2000.09.01. Notification) 2. Registration Utility Model No. 276526 (Elevator Life Safety Net) (Announced on 24 May 2002) The first leading technology is a safety device of an elevator used in a construction site, and the elevator moves while the slide moves by a motor that is forward and backward driven by the on / off of the limit switch touched by the elevator when the elevator is lifted according to expectations. It is prepared for the fall of the elevator by installing a multi-level safety net that opens and blocks the furnace. This first leading technology minimizes the fall distance and minimizes the impact of the fall, thus preventing fatal casualties.The elevator moving path is blocked by the safety net, and the construction materials being transported are prevented from falling to the floor of the site. It is possible to prevent damage to the external image that the construction company suffers from the accident. Next, the second leading technology relates to the safety net of general high-rise elevators, and when a person falls down the elevator, the elasticity of the rubber bar fixed to the wall of the hoistway absorbs the weight of the fall, and the air-injected mattress has a direct impact. It absorbs and protects life and trauma and maintains balance by pulling tightly the net and air mattress connected around the side of the air mattress, if the body falls out of the mattress if it falls on the edge of the air mattress. It will play a role. However, although the prior art as described above has a common purpose for the fall prevention device of the elevator, the first leading technology is used in the construction site, it is a design that can not be applied in general high-rise buildings. That is, there is a disadvantage that a space for retraction of the safety net must be provided on the side or the rear of the elevator car. In addition, the limit switch detects the movement of the elevator car and organically slides the safety net. If the electronic control device malfunctions, the elevator car and the safety net collide with each other to cause a larger accident. On the other hand, the second leading technology is installed in the bottom of the elevator passage in view of its configuration and operation, there is no guarantee that the elevator car stops at the upper side of the user, so when the elevator car stops at the bottom and the elevator door is opened, The user falls to the ceiling of the elevator car and cannot prevent an accident. In addition, assuming that the elevator user falls down to the floor of the elevator passage where the safety net is located, if the elevator user is on a high floor, there is a high possibility that the safety net may suffer intellectual and physical disability due to the impact falling from a high place. .

The present invention has been made to solve the above problems, it is provided to prevent the fall accident by installing a safety net overlap or spread at intervals corresponding to the height of the elevator car up and down to provide a fall prevention device of the elevator. It is.
