Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an emergency door for a screen door,

The present invention relates to a safety device for blocking a passenger from a line in a subway platform, and is characterized in that the upper and lower frames constituting the safety device are fixed to each other by a reinforcing bracket so as to be deflected by a load for a long time, And more particularly to a panic device capable of locking and releasing a lock and a hinge capable of automatically closing the door and adjusting the door clearance.

In the history of the subway, screen doors have been installed to block the platforms and lines from long ago. The screen door is centered on the movable door, and the emergency door is disposed on the left or right side and the fixed door is disposed on the opposite side.

Fixed doors occupy the same area as the emergency doors and are used as revenue projects by advertising using fixed doors.

However, when the subway arrives at the platform, if an emergency escape is attempted, it is blocked by fixed gate for some sections, which can lead to large-scale casualties.

In an emergency inside the subway, the passengers of the vehicle must be removed from the emergency doors and replaced with emergency doors so that the passengers can manually open and close the emergency or open doors anywhere.

Since the emergency door is composed of several components, it is required to design a structure for improving durability and safety of the emergency door.

Conventionally, for mutual assembly of several frame elements constituting a screen door emergency door, movable door, or fixed door framing, an upper frame and a lower frame are connected to a vertical frame Vertically cross-assemble. For this purpose, a hole is formed on the side surface of the vertical frame, and the bolt is passed through the bolt and assembled with a nut.

However, the long bolt shakes with the tolerance of the assembly section and the tightening force to the nut, and the door is sagged, and the emergency door does not operate normally.

In addition, since the upper and lower frame cutting surfaces and the vertical frame meet at right angles, the machining accuracy of the cut surfaces of the upper and lower frames is very important and affects the rectangular assembly of the window depending on the perpendicularity and flatness of the cut surface.

These problems can cause serious problems that the frame and the tempered glass come into contact with each other and break the tempered glass.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a screen door for solving the problems inherent in the prior art, and preventing door breakage and glass breakage caused by deflection.

In the present invention, the four corner portions of the upper and lower frames and the vertical frame are fixed by reinforcing brackets in order to prevent sagging of the emergency doors and flatten the level difference between the frame components constituting the emergency doors. To prevent the frame from being twisted, the assembly screws are further fixed to prevent sagging and warping.

According to one aspect of the present invention, a drive box in which a drive device is built on a pair of vertical columns installed vertically is assembled, and at the center of the drive box, a movable door operated by a drive device, A screen door provided with an emergency door capable of escaping in an emergency can be provided. At this time, the emergency door includes an upper frame and a vertical frame. The upper frame and the vertical frame are disposed at right angles to each other. A first fixing hole formed on the upper portion of the vertical frame and a fixing hole formed on the upper frame are fixed to each other by a first fixing screw. The upper stepped surface of the upper frame and the side stepped surfaces formed on the vertical frame are flush with each other. And a first reinforcing metal fitting fitted to the upper stepped surface and the side stepped surface is fitted in the upper stepped jaw formed on the upper stepped surface and the side stepped jaw formed on the right and left of the side stepped surface. The first reinforcing metal fitting hole formed in the first reinforcing metal fitting is aligned with the first fixing hole formed in the upper stepped surface and the side stepped surface, The holes are fixed to each other by a first rivet.

At this time, the emergency door may further include a lower frame. The lower frame and the vertical frame are disposed at right angles to each other. A second fixing hole formed in a lower portion of the vertical frame and a fixing hole formed in the lower frame may be fixed to each other with a second fixing screw. The lower stepped surface of the lower frame and the side stepped surfaces formed on the vertical frame may be flattened to each other. And a second reinforcing metal fitting disposed to abut the lower stepped surface and the side stepped surfaces may be inserted into the lower stepped shoulder formed above and below the lower stepped surface and the inside of the side stepped jaw formed to the left and right of the side stepped surface, have. The second reinforcing metal fitting hole formed in the second reinforcing metal fitting is aligned with the second fixing hole formed in the lower stepped surface and the side stepped surface, The holes may be fixed to each other by a second rivet.

At this time, a space for accommodating the panic device may be secured in the vertical frame.

At this time, it may further include a vertically extending intermediate column disposed adjacent to the emergency gate. When the emergency door is closed, a fixing pin for fixing the panic device embedded in the vertical frame is fixed to the intermediate pillar, so that the emergency door can not be opened.

At this time, the door closure which can be automatically closed after the emergency escape by using the emergency door can be disposed in the lower space of the lower frame.

In this case, a door trim device is embedded in the upper frame so as to adjust the door clearance of the emergency door, and a door clearance adjusting screw of the door clearance adjusting device is turned through an adjusting hole provided on the upper side of the vertical column to adjust the door clearance .

The screen door according to the present invention has a rigid structure and has an effect of preventing sagging of an emergency door, and is easy to adjust the door clearance. Also, glass breakage due to sagging is prevented, and it is applicable not only to emergency doors but also to fixed doors and movable doors.
