Claims (1)

[Scope of claims for utility model registration] (1) Each panel _P1 making up the shutter curtain
Upper guide roller 1 protruding from both left and right ends of _P8
A pair of left and right roller chains 3 with roller shafts 2 attached at predetermined intervals are driven by a sprocket 4 rotating in the shutter opening/closing direction, and the sprocket 4 is rotated in the shutter opening direction to wind up the roller chain 3. At this time, each of the panels _P1 to _P8 sequentially rises in a vertical state, and each panel _{P1 to P7} except the bottom panel P8 forming the lower end of the shutter curtain moves up to the sprocket 4 while maintaining the vertical state. In a panel shutter that passes through the storage rail 5 that guides the upper guide roller 1 and is stored adjacent to the front and back along the rail 5, the top panel _P1 forming the upper end of the shutter curtain is Guide rollers are attached to the extra length portions 3a of each of the roller chains 3 suspended from the sprocket 4 to be raised and lowered at a constant distance from the roller shafts 2 of the upper guide rollers 1 protruding from both left and right ends of the top panel _P1 . 10 roller shafts 11 are attached, each guide roller 10 is connected at one end side to be movable up and down with respect to the upper part of the top panel _P1 , and is foldable in the moving direction of the top panel _P1 . A panel shutter characterized in that it is supported by a bearing 14 provided on the other end side of a member 13 and guided along the storage rail 5. (2) Each panel _P1 that makes up the shutter curtain
Upper guide roller 1 protruding from both left and right ends of _P8
A pair of left and right roller chains 3 with roller shafts 2 attached at predetermined intervals are driven by a sprocket 4 rotating in the shutter opening/closing direction, and the sprocket 4 is rotated in the shutter opening direction to wind up the roller chain 3. At this time, each of the panels _P1 to _P8 sequentially rises in a vertical state, and each panel _{P1 to P7} except the bottom panel P8 forming the lower end of the shutter curtain moves up to the sprocket 4 while maintaining the vertical state. In a panel shutter that passes through the storage rail 5 that guides the upper guide roller 1 and is stored adjacent to the front and back along the rail 5, the top panel _P1 forming the upper end of the shutter curtain is Shifting to the storage rail 5, the slack of the extra length 3a is at a position where the extra length 3a of each roller chain 3 that suspends the top panel P ₁ from the sprocket 4 and raises and lowers it becomes slack and hangs down. A panel shutter characterized in that anti-sway guides 17 are provided at both left and right ends of the top panel _P1 to prevent it from swinging outward from lower guide rollers 8 protruding from the top panel P1.
