1 to 6, the elevator exit opening / closing apparatus of the elevator of the present invention is generally divided into an upper structure 100 and a lower structure 200, a binding means 140, and a shock absorber 300.

The upper structure 100 includes a fixed frame 120 fixed to the lower end of the ceiling plate 110 of the elevator 110 around the exit port 10 And a hinge 130 formed at one end thereof.

' 형태인 상기 고정브라켓(122)의 양 측벽 외면에는 상기 돌기를 수용하는 홈이 형성되며, 상기 고정프레임(120)의 돌기와 상기 고정브라켓(122)의 홈을 서로 끼워 맞추는 방식으로 상호 고정할 수 있는 것이다.More specifically, the stationary frame 120 may be in the form of an extruded bar having a cross-section of an 'e' shape (see FIG. 5), and a stationary bracket 122 fixed to the ceiling plate 110 as an upper space And is internally fastened. A plurality of the fixing brackets 122 can be fixed to the lower end of the ceiling plate 110 through the first fixing screws 122a and the fixing frame 120 can be fixed to the fixing brackets 122 . In other words, projections protrude from the inner wall of both sides of the upper space of the fixed frame 120,

The protrusions of the fixing frame 120 and the grooves of the fixing bracket 122 may be fixed to each other in such a manner that the protrusions of the fixing frame 120 and the fixing bracket 122 are fitted to each other. It is.

Of course, in order to improve the fixing force of the fixed frame 120, the second fixing screw 123 may be passed through the fixing frame 120 to both sides thereof to be fixed to the fixing bracket 122.

The lower structure 200 is disposed below the upper structure 100 and opens and closes the opening of the ceiling plate 110. One side of the lower structure 200 is connected to the hinge 130 and is rotatable from the hinge 130 A lower door plate 220 in the form of a flat plate provided at the lower end of the door frame 210 to close the inner space of the door frame 210, And an upper door plate 220 'in the form of a flat plate, which is installed on an upper portion of the upper door plate 210.

The illuminating unit 230 emits light into the elevator inside the door frame 210 between the upper door plate 220 'and the lower door plate 220. The illuminating lamp may be a fluorescent lamp, There is no restriction on the type of light that can emit light by the supply.

The binding means 130 is installed at an opposite end of the upper structure 100 and the lower structure 200 where the hinge 130 is formed and the lower structure 200 is hinged about the hinge 130 The lower structure 200 is separated from the upper structure 100 and can be pivoted about the hinge 130 when the binding means binding 130 is released from the fixing state of the upper binding structure 130. On the other hand, .

To this end, the binding means 130 may be a push-to-close type latch which is fixed at the time of pressure application and is released from being fixed at the time of pressing.

As one example of such a push-to-close latch, the binding means 130 includes a pin latch 141 fixed to the fixed frame 120, And a keeper 145 fixed to the door frame 210.

In this case, the pin latch 141 includes a pin body 142 fixed to the fixed frame 120, a slide sleeve 144 vertically movable up and down from the lower end of the pin body 142, And a spring 143 formed to surround the outer surface of the pin body 142 at an upper portion of the keeper 145. The keeper 145 has a hole 146 through which the pin body 142 passes, Plate type.

Accordingly, when the door frame 210 is raised, the keeper 145 is lifted and the slide sleeve 144 is lifted when the slide sleeve 144 is pressed, and the pin body 142 is inserted into the hole 146 The keeper 145 is fixed to the pin latch 141 and the keeper 145 is released from the pin latch 141 when it is pressed again in the fixed state.

The pin latch 141 of the binding means 130 may be fixed to the door frame 210 and the keeper 145 may be fixed to the fixed frame 120. [

In this case, the pin latch 141 is fixed to the door frame 210, and the slide sleeve 144 is vertically movable up and down from the upper end of the pin body 142 The spring 143 is formed to surround the outer surface of the pin body 142 at a lower portion of the slide sleeve 144.

The pin latch 141 is lifted by the elevation of the door frame 210 so that the pin latch 141 is fixed to the keeper 145 when the slide sleeve 144 is pressed by the keeper 145, The fan latch 141 can be separated from the keeper 145 when the door frame 210 is pressed again in the fixed state, thereby rotating the door frame 210 downward.

The cushioning shock absorber 300 may be of a gas-type or a hydraulic-type. The first shock absorber 310 may be rotatably connected to the securing frame 120, (320) is rotatably connected to the door frame (210).

Accordingly, when the door frame 210 is rotated downward from the hinge 130, the downward speed is reduced by the gas pressure or the hydraulic pressure so as to open slowly, thereby preventing a safety accident caused by the impact.

FIG. 7 is a plan view of the emergency opening / closing device of the elevator ceiling provided with the lighting means according to another embodiment of the present invention, and FIG. 8 is a sectional view of the elevator ceiling emergency opening and closing device having the lighting means according to another embodiment of the present invention 9 is an explanatory diagram of a state of use of an emergency opening and closing device and a ladder of an elevator ceiling provided with a lighting means according to another embodiment of the present invention.

7 to 9, a ladder member 400 may be fixed to the upper end of the upper door plate 220 'through a fixing member 410 such as a band or a belt, It may be a structure that can be stretched in length by a folding or antenna method.

When the lower structure 200 is opened, the ladder member 400 is extended to extend the ladder member 400 to allow the escape to the escape opening.

Hereinafter, the operation of the emergency opening / closing apparatus of the elevator ceiling equipped with the lighting means of the present invention will be described.

The lower structure 200 is fixed to the upper structure 200 in a state parallel to the upper structure 100 through the hinge 130 on one side and the binding means 130 on the other side, The exit port 10 of the lower structure 110 is closed and the illumination unit 230 formed in the inner space of the lower structure 200 diffuses the light into the elevator.

When the escapee pushes up the lower structure in the elevator when an emergency occurs, the binding means 140 of the push-to-close latch structure is released, and the hinge 130 of the lower structure 200 is pivoted downward from the hinge 130, At this time, since the pivoting speed is slowed by the shovel 300, the shock due to the sudden opening can be alleviated, and collision with a passenger can be avoided.

The upper door plate 220 'is exposed to the inside of the elevator when the lower structure 200 is completely moved downward. Thus, in the case of the embodiment having the ladder therein, the fixing member 410 temporarily fixed is released and the ladder member 400 can be taken out, and then the ladder can be escaped by extending the length toward the exit port 10.

Although the present invention has been described in connection with the preferred embodiments described above, it will be appreciated by those skilled in the art that various other modifications and variations can be made without departing from the spirit and scope of the invention, All such changes and modifications are intended to be within the scope of the appended claims.
