【Example】

 An embodiment of this invention will be described below with reference to the drawings. FIG. 1 is a schematic front view of a panel shutter according to an embodiment of the present invention, and FIG. 2 is an enlarged sectional view taken along the line AA of FIG. 1. In FIG. 1, 1 stands upright on both sides of a shutter opening / closing opening. The guide rails 1 are a pair of left and right guide rails, and each of the guide rails 1 is a U-shaped member having a vertically elongated opening 1a for guiding the panel up and down, as shown in FIG.

A panel storage box (hereinafter referred to as a storage box) 2 is arranged above the guide rail 1.

In the storage box 2, a pair of left and right sprocket (not shown) for raising and lowering the panel located above the doorway, and a panel located near the upper part of the sprocket and extending in the panel storage direction. A support rail (not shown) for suspending and storing the storage is arranged.

A pair of left and right chains 3 that can move up and down in the guide rails 1 and move to the support rails in the storage box 2 are meshed with the sprocket.

These chains 3 suspend and connect a plurality of upper and lower panels 4 and 5 which are driven to move up and down along the guide rails 1.

FIG. 3 is an enlarged sectional view taken along the line BB of FIG. 1, and FIG. 4 is an enlarged sectional view taken along the line C-C of FIG. Side rails 6 and 7 are attached to the upper and lower ends of the rails 5 and 5, respectively.

In these horizontal frames 6 and 7, a rising outer wrap piece 61 on the outdoor side and a rising overlap piece 62 on the indoor side are integrally formed at the upper end of the upper horizontal frame 6, and The overlapping pieces 61, 62 are formed with a fitting recess 63 for fitting the lower horizontal frame 7 of the upper panel 4 adjacent to the overlap pieces 61, 62 between them in a freely detachable manner. 63 has a fitting groove 64 along the rising overlap piece 61 on the outdoor side.

On the other hand, at the lower end of the lower horizontal frame 7, there is integrally formed a fitting projection 71 for fitting in the fitting recess 63 of the lower panel 5 adjacent to the lower horizontal frame 7. The portion 71 has a hanging overlap piece 72 for fitting and engaging with the fitting groove 64 of the upper horizontal frame 5.

Further, a stepped recess 73 is formed on the outdoor side of the lower horizontal frame 7 so that the rising overlap piece 61 on the outdoor side of the lower horizontal frame 6 can be fitted therein.

In the lower horizontal frame 7, a movable fin 8 is rotatably attached to the interior of the fitting convex portion 71.

The movable fin 8 integrally has a leg piece 81, and a shaft portion 82 integrally formed at a base end portion of the leg piece 81 is integrally formed at a side wall portion of the fitting convex portion 71 on the indoor side. The movable fin 8 is attached to the inside of the fitting convex portion 71 by rotatably fittingly engaging the bearing portion 74.

[Effect of device]

 As described above, according to the present invention, a movable fin is rotatably provided on one of the upper and lower horizontal frames of a plurality of upper and lower panels that are vertically driven along the left and right guide rails. When moving up and down, the panels are rotated and displaced to a vertical posture position that closes the horizontal frames between the panels, and when the panels are fully closed, the movable fin is moved by pushing the movable fin with the other horizontal frame adjacent to the one horizontal frame. Since the fins are configured to pivotally move to a substantially horizontal position, the horizontal frame strength of each panel can be automatically increased by the movable fins when the panels are fully closed. Therefore, the frame thickness and panel thickness etc. It is possible to obtain a sufficient frame strength against external pressure such as wind pressure without increasing the air pressure, and the wind pressure resistance and rigidity when the panel shutter is fully closed are significantly improved compared to the conventional method.

Further, when the panels are moved up and down, a gap is created between the panels to release the pressing force of the opposing side frame against the movable fins, and the movable fins are rotatably displaced to the vertical posture position. The panels can be smoothly moved up and down and stowed without fear of being disturbed by the movable fins, and the movable fins can close gaps between the panels when the panels are moved up and down. There is also the effect that there is no risk of fingers etc. being caught in the gap.
