A bridge-shaped shaft end holder 11 that straddles the wire take-up pulley 9 and the drive sprocket 10 is fixed to the bracket 5, and the shaft end holder 11 is provided with a cylindrical bearing 12 concentric with the shaft 7. The take-up cylinder 13 around which the shutter curtain 21 is wound is rotatably supported by the bearing 12.

A fixing plate 14 through which the rotating shaft 8 passes freely is provided inside the winding cylinder 13. The fixed plate 14 and the one cylindrical bearing 1 are concentric with the rotating shaft 8.
A torsion coil spring 15 is provided between the first and second fixing members 14, and one end of the torsion coil spring 15 is fixed to the first fixing plate 14 and the other end is fixed to the cylindrical bearing 12.

An intermediate shaft 16 is provided on each of the brackets 5 on both sides in parallel with the rotary shaft 8. The intermediate shaft 16 is provided with an idle pulley 17, a driven sprocket gear gear 18, and a guide sprocket gear for the shutter curtain 21 from the bracket 5 side. 19 is rotatably provided, and the driven sprocket gear 18 and the guide sprocket gear 19 are integrally fixed.

Here, the guide sprocket gear 19
And the diameter of the wire winding pulley 9 is the same.

A chain 20 is wound around the driving sprocket 10 and the driven sprocket gear 18,
The guide sprocket gear 1 is driven by the motor 27.
9 is forcibly driven.

The shutter curtain 21 is a slat 22
Are connected by a bending member 23.
Pipes 24 are projected from both ends of the guide sprocket, and the pitch between the pipes 24 is set to be the same as the tooth pitch of the guide sprocket gear 19.

The shutter curtain 21 is wound around the take-up cylinder 13 and the extended shutter curtain 21 is wound around the guide sprocket gear 19, and the pipe 24 is meshed with the guide sprocket gear 19. The pipe 24 is fitted on the guide rail 3 so that the shutter curtain 21 slides along the guide rail 3.

A wire 25 is attached to the end of the shutter curtain 21 and the wire 25 is connected to the end pulley 2.
6. Wrap the idle pulley 17 and wind it around the wire take-up pulley 9.

The operation will be described below.

In order to extend the shutter curtain 21 to the light blocking state, the motor is driven to rotate the rotating shaft 8 in the extending direction of the shutter curtain 21. The rotation of the rotary shaft 8 winds the wire 25 around the wire winding pulley 9 and pulls out the shutter curtain 21. The rotation of the rotary shaft 8 is transmitted to the take-up cylinder 13 via the torsion coil spring 15, and the shutter curtain 21 is extended.

At the same time as the shutter curtain 21 is extended, the wire 25 is wound on the wire winding pulley 9. Here, as described above, since the pitch circle of the guide sprocket gear 19 and the diameter of the winding drum of the wire winding pulley 9 are the same, the feeding speed of the shutter curtain 21 and the winding speed of the wire 25 become the same. The wire 25 is wound without slack and without excessive tension.

The wire winding pulley 9 and the winding cylinder 13 have different diameters (in this embodiment, the winding cylinder 13 has a large diameter), and the feeding speed of the shutter curtain 21 is forced by the guide sprocket gear 19. Therefore, there is a difference in rotation between the rotating shaft 8 and the winding cylinder 13. Further, when the shutter curtain 21 is extended, the winding diameter of the shutter curtain 21 also changes, but a change in the rotation also occurs due to the change in the winding diameter. Such a rotational difference is absorbed by the torsion coil spring 15, and the torsion coil spring 15 generates a repulsive force in the anti-pull-out direction.

When the shutter curtain 21 is fully extended, the torsion coil spring 15 has
The rotation speed obtained by subtracting the total rotation speed of the winding cylinder 13 from the total rotation speed of the rotating shaft 8 is accumulated as a displacement.

Next, when the shutter curtain 21 is wound, the motor is rotated in the reverse direction so that the shutter curtain 21 is wound around the winding cylinder 13 in an operation reverse to the above operation.

Incidentally, by appropriately changing the pitch circle of the guide sprocket gear 19 and the diameter of the winding drum of the wire winding pulley 9, it is possible to appropriately select the difference in the number of rotations between the rotating shaft 8 and the winding drum 13. Needless to say.

Further, the slat 22 may be made of a synthetic resin, an aluminum drawn material, a plate-formed product, or the like, and it is a matter of course that the connection structure can be variously changed.

Instead of the pipe 24 and the guide sprocket gear 19 projecting from the end of the shutter curtain 21, a timing belt is attached along the end of the shutter curtain and a timing gear meshing with the timing belt is provided. You may.

Further, the driving sprocket 10 and the driven sprocket gear 18 may have different pitch circles so that the rotating shaft 8 and the winding cylinder 13 have a required rotation difference.

In the above embodiment, the rotating shaft 8 is rotated by the motor. However, the rotating shaft 8 may be freely rotated and the winding cylinder 13 may be rotated by the motor. In this case, the wire take-up pulley 9 is
On the side.

[0030]

According to the present invention, as described above, the following excellent effects are exhibited.

The roofing material can be made of a rigid material, and can be prevented from bending or fluttering against wind, rain, and snow, and can easily remove snow even when snow falls.

Since the roofing material has rigidity in the width direction and can bend in the opening and closing directions, it can be applied to a bent portion.

The shutter can be opened and closed without any trouble even if the winding diameter of the shutter curtain changes.

The present invention can be applied to a large opening.
