Further, for example, when wind pressure is applied to the closed opening / closing body 3 from one side of the area 6 that separates the opening, in FIG. 5, the upper reinforcing body 20 rotates the boundary between the upper reinforcing body 20 and the upper frame 15 as a center of rotation of the upper panel 10A. Attempts to fall toward the center 10Z side and toward the center 10Z side of the upper panel 10A with the lower reinforcing body 21 as the center of rotation at the boundary with the lower frame 16 are attempted. Force is received by the contact surfaces 72; 72 of the one edge side reinforcement plate 67 and the other edge side reinforcement plate 69, and the reinforcement body collapse prevention means 60 resists the force of the reinforcement body to fall. Can prevent falling.

  That is, since the reinforcement body and the surface of the panel on one side of the region 6 are connected by the reinforcement body collapse prevention means 60, the upper reinforcement body 20 is tilted toward the opening 2 side around the boundary with the upper frame 15 as the rotation center. It is possible to prevent the lower side reinforcement body 21 from collapsing toward the opening 2 side around the boundary with the lower frame 16 as the center of rotation, and it is possible to prevent deformation of the panel due to the collapse of the reinforcement body.

Note that the same reinforcement collapse prevention means 60 is used in different directions when connecting the upper reinforcement 20 and the panel and when connecting the lower reinforcement 21 and the panel.

It has the function of staying above.

When the operator lifts the open / close body 3 in the closed state and performs an opening operation to open the opening 2, the operator sequentially moves the uppermost panel of the open / close body 3 to the upper guide portion 43 so as to be bent one by one. . Then, by continuing the opening operation, the opening / closing body 3 moves to the upper guide portion 43, and the opening 2 is fully opened.
On the other hand, when the opening 2 is closed, the operator pulls the operating portion such as a lowering string (not shown) attached to the lower panel downward to pull down the opening / closing body 3 along the vertical guide portion 41. Take action. When the opening / closing body 3 is closed, the panels located on the side of the opening 2 among the plurality of panels on the upper guide 43 are sequentially moved to the vertical guide 41. Then, by continuing the closing operation, the opening / closing body 3 moves to the vertical guide portion 41, and the draining seal 25 provided at the lower end of the lower panel 10B located at the lowermost portion comes into contact with the opening lower end of the floor surface, the ground, or the like.
