Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the entire shutter device according to the first embodiment. FIG.
FIG. 2 is a sectional view taken along line II. First, the basic structure and operation of the shutter device common to the embodiments will be described.

In FIG. 1, a pair of left and right brackets 1 are arranged in a space S above the ceiling of a building, and these brackets 1 are attached to a building body existing in the space S above the ceiling. A winding shaft 3 around which a shutter curtain 2 of the shutter device is wound is rotatably hung. The shutter device according to this embodiment is a disaster prevention shutter device that forms a disaster prevention section in a building and blocks the progress of flame and smoke when a fire occurs, and all or a main part of the shutter curtain 2 is made of silica cloth. Alternatively, it is formed of a glass cloth itself or a fire-resistant sheet in which a fire-resistant paint is applied thereto.

The left and right ends of the shutter curtain 2 are inserted into left and right guide rails 6 attached to immovable bodies 5 such as walls and columns existing in the room below the ceiling 4.
The shutter curtain 2 is rotated by the forward / reverse rotation of the winding shaft 3.
The opening and closing operation of the shutter curtain 2 is performed while the left and right ends of the shutter curtain 2 are guided by the guide rail 6. At the left and right ends of the shutter curtain 2, there are provided retaining members 7 such as bolts and nuts for preventing the left and right ends from coming off the guide rail 6.

A switch 8 is attached to one bracket 1 of the pair of left and right brackets 1.
Is a combination of the motor 9 and the brake 10. The drive shaft of the motor 9 is connected to the winding shaft 3 via a power transmission means 11 composed of a sprocket and a chain, and the rotation of the drive shaft is stopped when the brake 10 is turned on. .

The seat plate 12 provided at the lowermost portion of the shutter curtain 2 normally rises to the position of the lintel for passing through the shutter curtain formed on the ceiling 4 at this time. Since the seat plate 12 is turned on, the seat plate 12 is stopped at the lintel position. When a fire occurs and the flame, smoke or heat due to the fire is detected by a sensor (not shown), the brake 10 is turned off by a signal from the sensor. As a result, due to the weight of the seat plate 12 and the shutter curtain 2, the shutter curtain 2 descends while rotating the winding shaft 3, and the shutter curtain 2 is fed out from the winding shaft 3 and the seat plate 12 reaches the floor 13. Thereby, the shutter curtain 2 is fully closed.

The above is the case where the shutter device is of an automatic closing type using a sensor. However, when the shutter device is of a manual closing type, operating members such as levers are manually operated when a fire occurs. Then, the brake 10 is turned off, and similarly, the shutter curtain 2 is lowered by the weight of the seat plate 12 and the shutter curtain 2 to be in a fully closed state.

When a switch (not shown) is operated, the motor 9 is driven, whereby the take-up shaft 3 is rotated via the power transmission means 11 in the direction opposite to the direction in which the shutter curtain 2 is lowered. As a result, the shutter curtain 2 is wound up by the winding shaft 3 and rises. When the seat plate 12 reaches the position of the lintel, the motor 9 stops and the brake 1
0 turns on.

The shutter curtain 2 occupies most of the shutter curtain 2 and forms a curtain basic member 1 made of a refractory sheet, which forms the basic part of the shutter curtain 2.
