Generally, the screen door system is a kind of safety device that cuts off the railroad track, which is the light railway, subway train, and the platform where passengers ride the train.

Such a screen door is provided with a fixed frame having a door rail fixed to the platform to block and distinguish the platform and the railway on the platform of the electric car. The fixed frame is interlocked with each door of the electric train, A plurality of sliding doors which are slid along the door rail and are opened and closed at the same time as the respective doors are provided.

When the screen door is configured as such, the movable door that is interlocked with the door of the electric car is opened or closed when the electric car enters or departs from the platform. When the electric car stops after entering the platform, the movable door is automatically opened simultaneously with the door, And the movable door is automatically closed at the same time as the entrance door before the departure of the passenger on the railway car is completed.

As a result, the passengers are dropped from the platform to the railway to prevent the risk of safety accidents and ensure safety. In addition, strong winds generated during the operation of the electric trains keep the train platform and dust from entering the platform. And the heating and cooling effect can be increased.

On the other hand, the screen door has a plurality of emergency doors for moving a passenger on an electric train from a train to a platform or from a railway to a platform when an emergency occurs such as an accident or sudden stop of a train, Or the movable door itself is used as an emergency door.

Since the emergency door is provided so as to be openable and closable in the fixed frame so as to serve as a passageway for passengers moving from the railway to the platform, the emergency door is provided with a panic bar for manually opening and closing the emergency door, , The passenger moving from the track to the platform moves the panic bar by pushing or turning it so that the emergency door is opened so that the passengers move from the rail side to the platform through the opened emergency door, It is closed.

A movable door serving as an emergency door or an emergency door and an opening / closing device for realizing the emergency door are applied to the field in various embodiments. Among them, a device for manually opening the door of the screen door Registered Patent Publication No. 10-1044446). &Quot;

In the screen door having an opening / closing door that is opened and closed by sliding on the left and right sides by an electrical signal of an automatic opening / closing system, And a bracket 23 fixed to the frame 11 of the opening and closing door 10 is fixed to the other side of the rotary door 26. The rotary bracket 26 is provided inside the rotary bracket 26, (20) fixedly attached to a distal end of a shaft (21) of the emergency handle (20) in a direction opposite to the emergency handle (20), the emergency handle The electric rotating machine according to claim 1, further comprising: a rotating piece (25) which rotates in the same direction in accordance with the rotation of the frame (11)

A vertical rod 30 which is moved up and down toward the lock rod 5 at a position vertically opposite to the lock rod 5 for locking and unlocking the opening and closing door 10 by a door; And a guide bracket 33 for guiding the vertical rod 30 to be vertically moved without shaking. When the user holds the knobs on both sides and rotates in a direction opposite to each other, the lock state of the opening / Therefore, it is possible to easily open the opening / closing door on the railroad side even in an emergency situation in which the opening / closing door is not normally operated, thereby reducing safety accidents of passengers.

However, the "manual opening device for the door of the screen door" of Patent Document 1 has a configuration in which the user must hold the knobs on both sides and rotate in the direction opposite to each other, so that the operation can not be performed at one time , There is a disadvantage that a lot of power is required for operation.

The contact portion 121 is contacted with the terminal by pressing the contact portion 121 as the motion cam 140 rotates in the counterclockwise direction so that an electrical signal is transmitted to the door control portion 11 .

When the motion cam 140 rotates in the clockwise direction, the first bending portion 144 is formed in a shape of "? &Quot; on one side of the motion cam 140, So that the motion cam 140 is prevented from rotating more than the predetermined rotation amount, thereby maintaining the coupling relationship between the components and enabling more stable driving.

At this time, it is preferable that the rotation angle of the motion cam 140 is set between 5 and 20 degrees in forward and backward directions F and B, respectively.

The second bending portion 145 is a component having the same function as the first bending portion 144. The second bending portion 145 is formed at one side of the motion cam 140, When the cam 140 rotates in the counterclockwise direction, it is supported by the second step portion 152 of the rotation limiting angle 150 to be described later, thereby preventing the motion cam 140 from rotating more than the predetermined rotation amount, Thereby maintaining the relationship and enabling more stable driving.

The first engaging part 146 is formed as a curved recessed part of the lower portion of the motion cam 140. The first engaging part 146 seats the contact part 121 on the depression 141, State. That is, the upper portion of the ball flange 160 formed at the lower portion of the rotation restricting angle 150 is inserted in a state where the terminal is not contacted to the switching unit 120, so that the motion cam 140 is arbitrarily rotated It is possible to prevent.

The second engaging part 147 is formed as a component that is curved and extended on the other side of the first engaging part 146. The second engaging part 147 is formed by the contact part 121, The upper portion of the ball flanger 160 is inserted in a state in which the terminal cam 142 is pressed and the terminal contact is made, thereby maintaining the current position of the motion cam 140.

The third latching part 148 is a component that is curvedly formed on one side of the first latching part 146. The third latching part 148 is a part of the third latching part 148, The upper portion of the ball flanger 160 is inserted in a state in which the terminal 143 is pressed by the cam 143 to maintain the current position of the motion cam 140.

On the other hand, in the present invention, when the shaft 130 is rotated clockwise or counterclockwise, the rotation of the motion cam 140 is restricted in the U- A first restricting angle 150 is formed on the other side of the rotation restricting angle 150. A first restricting portion 151 is formed on the other side of the rotation restricting angle 150 so as to abut the first bent portion 144. The rotation restricting angle 150 A second step portion 152 is formed to abut on the second bent portion 145. [
