{Curved screen arson shutters}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a curved type fire screen shutter, and more particularly, to a curved type screen screen shutter in which a fire screen wound around an outer diameter of a screen shaft fixed to a round bar is wound and unwound through an independent guide bearing protruding from both sides of the shaft drum to the inside diameter The present invention relates to a curved type fire screen shutter that allows a plurality of screen shafts to be driven through a single deceleration motor without a power surge even though the screen shafts are curved.

Generally, a fire-retarding shutter is one of refractory structures installed to prevent a fire from spreading to the inside of a building in the event of a fire. It prevents the entrance of outside people into a specific space and also prevents fire, smoke and toxic gases (Hazardous) factors and prevent them from evolving from the ignition point. The device is provided in a restricted emergency exit so that people in the fire space and the fire space can be quickly and safely evacuated.

Such a fire-retarding shutter is usually constituted by a drive device installed in a ceiling surface and a shutter driven by the drive device and descending to the bottom surface side. The material of the shutter is divided into a steel shutter made of iron and a screen shutter composed of a screen In recent years, screen shutters composed of screens are mainly installed, and fire screening sheets are mainly used as screens.

Therefore, the screen shutters are lowered in the area where the fire is generated inside the building, so as to block the internal compartment of the building, the flame, smoke and toxic gas are prevented from spreading from the fire area, So that damage can be minimized.

In addition, since the emergency shutter door is provided in the screen shutter, people can escape from the fire area through the emergency door even if the screen shutter is lowered when a fire occurs.

However, the conventional screen shutter device is not horizontally maintained due to the deflection of the screen and the shaft winding the screen, and the screen shaft is rotated and overlapped while being in contact with each other at a portion where the screen and the screen are overlaid with each other, There is a problem that the screen is not smoothly moved up and down during the elevating operation.

The airtightness and airtightness of the screen are greatly deteriorated. Thus, the problem that the flame, smoke, and toxic gas generated from the fire area can not be properly blocked from spreading to other areas can not be solved.

Particularly, in the case of a screen installed at the corner area, there is a problem that a safety accident occurs largely because the screen and the screen are opened and the door is opened,

On the other hand, Patent Registration No. 1348122 (registered on Dec. 31, 2013) requires various parts such as hoisting wire, wire drum and main body (housing), which is a disadvantage of high installation cost and installation cost, Maintenance and management were impossible.

Patent Registration No. 1300908 (Registered on Mar. 08, 2013) is incapable of installation and operation, and tearing of the screen occurs, which is very difficult to use for fire protection.

Patent No. 1531857 (registered May 2015, June 22, 2015) has a disadvantage in that the screen is separated and constructed so that the cracked screen is detached, so that the fire function is deteriorated when a fire occurs.

Patent registration No. 1259521 (Registered on Mar. 24, 2013) is designed to divide the screen so that the glain screen is detached, so that the fire function is deteriorated when a fire occurs and the power is easily transmitted due to the angle of the universal joint There is a drawback that driving can not be performed smoothly.
