The present invention relates to a passenger fall prevention device of an elevator for preventing a fall accident that may occur in the process of exiting the passenger inside the elevator in the emergency, more specifically, the structure is provided on each floor The maintenance of floor display lamps is convenient and quick.

In general, elevators are mainly installed in high-rise buildings (buildings, apartments, etc.) to quickly carry passengers to a desired floor. The elevators 2 are formed on the wall 1, and the elevators and the platforms of each floor communicate with each other. An entrance 3 is formed, and an elevator 4 is installed in the elevator 2 to receive power generated in a machine room (not shown). The wall 1 is provided with a landing door 5 to selectively open or close the entrance and exit 3, and the wall 1 is exposed to the outside of the landing hall of each floor so as to adjust the lifting position of the lift 4. The floor display lamp 6 is installed for passengers to check outside.

Accordingly, when the passenger selects the elevator call button attached to the outside of the wall 1 at the platform, the elevator 4 installed inside the elevator 2 receives the power generated in the machine room and the passenger calls the elevator call button. Stop on the selected floor.

In this way, when the elevator 4 stops on the floor to which the passenger wants to board, the landing door 5 which has closed the entrance 3 is opened, and the door 3 is opened and installed in the elevator 4 so that the entrance 4 is stopped. An elevator door (not shown) interlocked with the landing door 5 is also opened, in which a passenger boards the elevator 4 through the open doorway 3 and is then attached to the inside of the elevator 4. By selecting the floor selection button, the landing door 5 and the door door which were opened are closed again, and the car 4 is lifted up to the floor selected by the passenger, so that the floor is quickly reached by the passenger.

On the other hand, when the elevator 4 is lifted, the lifting position of the elevator 4 is turned on the floor display lamp 6 installed on the wall 1 and exposed to the outside of each platform, which means that a passenger waiting at the platform is on the floor. This is to make it possible to check the position of the elevator car 4 by looking at the display lamp 6.

The elevator as described above does not stop exactly on the selected floor as shown by the solid line in operation, but stops between the floor and the floor as shown by the dashed-dotted line when the elevator is broken. Passengers in) must escape, and if the gap between the car and the wall 1 forming the hoistway 2 is greater than 125 mm, there is a risk that the escaping passenger will inadvertently fall into the gap. It is high and mandatory to have a passenger fall arrest system to prevent this.

Conventional passenger fall prevention device is a plurality of brackets (7) is fixed to the inner wall of the wall (1) of each layer, as shown in Figures 1 to 2 of the accompanying drawings, each bracket having a rectangular shape Fall prevention plate (8) is a structure that is fixed by the screw (9).

Therefore, if the elevator 4 does not stop exactly on the floor selected by the passenger when driving and stops with a dashed line in FIG. 1, the elevator is broken, so the passenger boarding the elevator 4 opens the opened landing door 5. When the passenger escapes in the process of escaping, the passenger must fall out of the fall prevention plate 8 located between the elevator 4 and the wall 1 so as not to fall. .

However, such a device is conventionally installed on the walls of each floor, when a technician checks or repairs a floor display lamp that allows the passenger to check the elevation of the elevator from the outside, a professional technician climbs to the top of the elevator to bracket the fall prevention plate. Loosen the screw that is fixed in the bracket, and remove the fall prevention plate from the bracket (7). After checking or repairing the floor display lamp, the fall prevention plate should be fixed to the bracket again. It was very inconvenient and the work time was long and there was a problem that parts are often lost.
