Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a billboard opening / closing apparatus for a screen door, and more particularly, to a billboard which is disposed in front of a screen door, So that the user can quickly evacuate the platform to the platform.

Generally, a screen door is composed of a fixed wall (screen) and a movable door which are isolated from a railway line on a subway or light rail platform, and the movable door is opened and closed in conjunction with a vehicle door.

Also, an emergency door can be installed on the fixed wall, and can be accessed through this emergency door when repairing the line or in an emergency.

Such a screen door is interlocked with a movable door such as a door of a vehicle when the vehicle is stopped in the landing groove, and when the vehicle starts, the movable door is closed to prevent the passenger from falling off the platform.

In addition, foreign matter such as dust generated when the vehicle runs on the line is blocked from entering the platform.

The emergency door installed on the fixed wall of the screen door is not only for the passengers but also for the maintenance of the railway line. Therefore, the emergency door must be kept closed normally, and opened only when necessary.

Therefore, a panic bar is provided on the line side surface of the emergency door and the emergency door is opened only when the operator presses the panic bar.

Since the space around the screen door is a free space, this free space is utilized for posting various information such as advertisements and informational messages.

Especially, since the subway station has a large number of people and the advertising effect is outstanding, the number of billboards installed in the front space of the screen door is increasing.

Such a billboard is usually arranged in front of an emergency door (platform direction) of a screen door, and can be advertised by attaching an advertisement poster to a panel mounted on the front of the billboard and illuminating the panel with light by a backlight.

However, in the case of a conventional screen door for a screen door, since the screen door and the billboard are separate structures, when a screen door is opened in a subway line in an emergency and evacuated to a platform, a screen door provided with some panic bars can escape, There is a problem that emergency escape is impossible when the vehicle stops at a section where the vehicle is not installed, that is, a section where the billboard is installed.

Hereinafter, a billboard opening / closing apparatus for a door screen according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 8, the screen door 1 is constituted by a fixed wall (screen) 3 and a movable door 4 which are isolated from a line on a subway or light railway platform, Is opened and closed in conjunction with the door of the door.

In the present invention, the emergency door is omitted in the space where the emergency door is installed, and the billboard 5 is installed in the space where the emergency door is installed, So that the billboard 5 can perform the function of the emergency door and the advertisement function at the same time.

This billboard opening / closing apparatus comprises a door frame (7, 8, 9, 10) arranged in a fixed wall (3) arranged at a position adjacent to the movable door (4); A billboard 5 hingedly coupled to an upper portion of the door frame 7, 8, 9, 10 so as to be vertically opened and closed about an upper portion thereof when an external force is applied thereto; Shovels 11 and 13 for pushing up the advertisement board 5 or the panel 12 upward; And a fixing part 14 mounted on the billboard 5 to fix the billboard 5 to the door frames 7, 8, 9, 10.

In the billboard opening / closing apparatus having such a structure, the door frame 7, 8, 9, 10 includes an upper horizontal frame 7 disposed on the upper portion of the fixing wall; A lower horizontal frame (8) disposed on the platform; And a pair of vertical frames (9, 10) arranged on the rim of the fixed wall and standing upright on the platform.

The billboard 5 can be opened and closed by being hingably connected to the door frame 7, 8, 9, 10 by the hinge pin P2.

In more detail, the billboard 5 is equipped with a panel 12 for displaying advertisement contents on the entire surface of the advertisement frame 16. A backlight B such as an LED is disposed behind the panel 12. [ Therefore, the advertisement contents can be recognized by the light from the backlight (B) and transmitted through the panel (12).

The billboard 5 is connected to the advertising frame 16 by a hinge structure so that the panel 12 can be opened or closed only when necessary.

A hinge pin P1 protrudes laterally from the upper portion of the panel 12 and a hinge groove is formed inside the advertising frame 16 to which the panel 12 is coupled. .

Thus, the upper portion of the panel 12 is hingedly connected to the inner upper portion of the advertising frame 16 so that only the panel 12 can be opened or closed, if necessary.

For example, when an LED or an electronic device of the backlight B is replaced, the panel 12 can be replaced while the panel 12 is pushed forward.

The entire panel 12 or the billboard 5 can be opened by being pushed by the shovels 11 and 13 described above.

More specifically, the shoeback includes a main shoe bar 11 for pushing up the entire billboard 5; And an auxiliary shock absorber 13 for pushing up the panel 12.

At this time, the main shock bar 11 and the auxiliary shock bar 13 mean a conventional gas shock absorber, that is, a shock absorber composed of a cylinder and a piston.

The main showbar 11 pushes up the entire billboard 5 by connecting the vertical frames 9 and 10 of the door frames 7, 8, 9 and 10 to the advertisement frame 16. That is, the cylinder at one end of the main shock bar 11 is fixedly connected to the vertical frames 9 and 10, and the piston at the other end is hingedly connected to the advertising frame 16.

Therefore, the main shock absorber 11 is pressed against the entire billboard 5 while being supported by the vertical frames 9 and 10. [

In this state, when the entire billboard 5 is pushed from behind or pulled from the front, the billboard 5 is lifted up by the main booster 11.

Therefore, the operator can lift the billboard 5 easily with a small force. When the billboard 5 is lifted up like this, the empty space is left in the space where the billboard 5 is located, so an emergency can enter and leave the space.

The cylinder of one side of the auxiliary shock absorber 13 is fixedly connected to the advertising frame 16 and the piston of the other end is hingably connected to the panel 12.

Therefore, the auxiliary shoe bar 13 is in a state of pushing only the panel 12 in a state of being supported by the advertisement frame 16.

Therefore, the operator can lift the panel 12 upward by pulling only the panel 12 from the front.

Since the main showbar 11 and the auxiliary showbar 13 can be attached to lift up the entire billboard 5 or lift up the panel 12 only when lifting the entire billboard 5, And when the panel 12 is repaired, only the panel 12 can be lifted and repaired to perform a complex function.

On the other hand, the fixing portion 14 is fixed so that the billboard 5 does not flow in a state where the upper portion thereof is hinged to the door frames 7, 8, 9 and 10.

8, the fixing portion 14 includes a support bracket 22 fixed to the advertising frame 16, a cover 24, a shaft 26, a push block 28, And includes a plate 35, an upper plate 39, a link plate 45, an upper connecting bar 47, a lower connecting bar 49, a torsion elastic member S, and a return spring 50 do.

More specifically, the fixing portion 14 includes a support bracket 22 fixed to the advertising frame 16 and formed with a pair of support pieces 23, a cover 24 covering the front surface of the support bracket 22, .

A shaft 26 coupled to the panic bar 25 and rotatable together with the pushing of the panic bar 25; A push block 28 rotatably coupled to the shaft 26 and having a hook is mounted.

The lower plate 35 is slidably disposed on the inner lower side of the support bracket 22 and can slide upward as the push block 28 rotates.

The lower plate 35 is formed with a hook locking projection 31 that is hooked on the hook 29 and a lower link projection 33 protruding downward from the hook locking projection 31 is formed.

The upper plate 39 is slidably disposed on the inner upper portion of the support bracket 22 so that the upper link protrusion 37 is formed so as to move downward as the push block 28 rotates.

A circular link plate 45 is disposed between the upper plate 39 and the lower plate 35. The link plate 45 is formed with a groove into which the lower link protrusion 33 and the upper link protrusion 37 are coupled and the center is coupled to the center shaft 43 formed on the base 41, And the upper plate 39 are linked to each other so as to integrally slide up and down.

An upper connection bar 47 is connected to an upper portion of the upper plate 39 and a lower connection bar 49 is connected to a lower portion of the lower plate 35.

An upper fixing protrusion 53 protrudes from the top of the upper connecting bar 47 and is inserted into an upper fixing hole 51 formed in the upper horizontal frame 7.

A lower fixing protrusion 57 protrudes from the lower end of the lower connecting bar 49 and is inserted into a lower fixing hole 55 formed in the lower horizontal frame 8.

The shaft 26 is disposed so as to surround the torsional elastic member S. Therefore, when the depressed panic bar 25 is released from external force, it returns to its home position by the elastic force of the torsional elastic member S.

A spring 50 is connected to the lower link projection 33 and the spring 50 is connected to the fixing bar 24 of the support bracket 22. Therefore, the lower plate 35 integrally connected to the lower link projection 33 maintains a state in which the lower plate 35 is pulled down by the retraction force of the spring 50.

As a result, the lower plate 35 is always kept pulled down by the spring 50, and the upper plate 39 is relatively lifted up by the link plate 45 so that the billboard is fixed On the other hand, when the panic bar 25 is pressed, the upper plate 39 is raised and the lower plate 35 is lowered due to its own weight so that the billboard 5 can be opened.

When the user first presses the panic bar 25, the shaft 26 is rotated and the push block 28 is rotated. .

As the push block 28 rotates, the hook rotates in the counterclockwise direction, and the hook pushes up the hook-hook protrusion 31 upward.

As the hook hooking protrusion 31 is raised, the lower plate 35 is also raised and the lower connection bar 49 connected thereto is also raised. Therefore, the lower fixing protrusion 57 inserted into the lower fixing hole of the lower horizontal frame 8 is detached.

When the lower plate 35 is lifted, the lower link protrusion 33 is lifted and the link plate 45 is rotated clockwise to be coupled to the groove of the link plate 45 through the upper link protrusion 37, The upper plate 39 is lowered.

Accordingly, the upper connecting bar 47 connected to the upper plate 39 is lowered, so that the upper fixing protrusion 53 inserted into the upper fixing hole of the upper horizontal frame 7 is detached.

As a result, the upper fixing protrusion 53 and the lower fixing protrusion 57 are simultaneously released from the fixed state by pressing the panic bar 25, so that the billboard 5 can be opened easily.
