[Problems to be Solved by the Invention] Since the panel of the conventional panel shutter is configured as described above, the wind pressure resistance and rigidity of the panel shutter are determined by the strength of the horizontal frame. However, there is a problem that the frame thickness (expected size) is greatly restricted due to the panel storage operation and the panel storage space. Therefore, in order to increase the second moment of area of the panel, it is necessary to increase the wall thickness and the spot size of the panel, and to provide a panel pull-out preventing bracket on the guide rail to cover the rigidity. There were problems such as a complicated structure and an increase in size.

The present invention has been made to solve the above-mentioned problem, and it is possible to automatically reinforce the horizontal frame of the panel when the panel is fully closed without providing a panel extraction fitting on the guide rail, Moreover, it is an object of the present invention to provide a movable frame reinforcing device for a shutter panel which can automatically close a space between horizontal frames of panels during a panel elevating operation.

[0005]

SUMMARY OF THE INVENTION A movable panel reinforcing device for a shutter panel according to the present invention is arranged along these guide rails so as to open and close a pair of left and right guide rails standing on both sides of a shutter opening / closing opening. In the horizontal frames provided at the upper and lower ends of the upper and lower multi-level panels driven up and down, in one of the upper and lower horizontal frames, in a vertical posture position that closes the space between the horizontal frames of each panel during the panel vertical operation. A movable fin is provided which is pivotally displaced and is pushed by the other lateral frame adjacent to the one lateral frame at the fully closed position between the guide rails and is rotationally displaced to a substantially horizontal posture position.

[0006]

With the movable frame reinforcing device for a shutter panel according to the present invention, when the upper and lower panels reach a position where the upper and lower panels fully close between the guide rails, the movable fins provided on the horizontal frame of each panel are adjacent to this. The frame strength against external pressure such as wind pressure is increased by being pushed by the side frame of the other party and rotationally displaced to a substantially horizontal posture position.

Further, when each of the panels is sequentially raised from the fully closed position, a gap is formed between the panels, so that the movable fin is released from being pressed by the side frame of the other party. The panel is pivotally displaced to a vertical position to close the space between the side frames, whereby the space between the side frames is automatically closed, so that there is no danger of fingers or the like being pinched between the side frames when the panel is opened and closed.
