The force applied is received by the contact surface 63a of the hooking plate 63, and the reinforcing member fall prevention means 60 resists the force that causes the reinforcing member to fall, so that the reinforcing member can be prevented from falling.
Further, for example, when wind pressure is applied to the opening/closing body 3 in the closed state from the side of the one region 6 across the opening, in FIG. Towards the center 10Z side and the lower reinforcing body 21 tries to fall toward the center 10Z side of the upper panel 10A around the boundary with the lower frame 16 as the center of rotation. The force applied is received by the contact surfaces 72; 72 of the one edge side reinforcing plate 67 and the other edge side reinforcing plate 69, and the reinforcing body fall prevention means 60 resists the force that causes the reinforcing body to fall down. It can prevent falling.

That is, since the reinforcing member and the surface of the panel on the one region 6 side are connected by the reinforcing member fall prevention means 60, the upper reinforcing member 20 falls toward the opening 2 with the boundary between the upper frame 15 as the center of rotation. It is possible to prevent the lower reinforcing body 21 from falling toward the opening 2 around the boundary with the lower frame 16 as the center of rotation, thereby preventing deformation of the panel due to the falling of the reinforcing body.

When connecting the upper reinforcing member 20 and the panel and when connecting the lower reinforcing member 21 and the panel, the same reinforcing member falling prevention means 60 is used with different orientations.
That is, when connecting the upper reinforcing body 20 and the panel, the inner surface 70u of the connecting plate 70 facing the other edge side reinforcing plate 69 is brought into contact with the reinforcing plate portion 13a of the frame reinforcing member 13, and the inclined plate 65 The extension edge 65t and the plate surface of the main plate portion 13x of the frame reinforcing member 13 are opposed to each other, and then the connecting plate 70 is attached to the reinforcing plate portion 13a.
When connecting the lower reinforcing body 21 and the panel, the outer surface 70f of the connecting plate 70 opposite to the inner surface 70u is brought into contact with the reinforcing plate portion 13a of the frame reinforcing member 13, and then the connecting plate 70 is attached to the reinforcing plate portion 13a.

The rotary shaft 51 is a hollow or solid shaft body, has a length substantially equal to the distance between the pair of guide means 4, 4, and extends in the width direction of the opening 2 above the upper end of the opening 2. It is extended and arranged. The rotating shaft 51 is rotatably supported by a plurality of bearing brackets 56, 56 . . .

The winding drum 52 is a bobbin-shaped (cylindrical) member that enables winding and feeding of the connecting member 53, and the central axis of the winding drum 52 and the central axis of the rotating shaft 51 are concentric. It is fixed to both ends of the rotating shaft 51 as shown in FIG.
The winding drum 52 is a member that rotates together with the rotary shaft 51 to wind the connecting member 53 onto the outer peripheral surface and to extend the connecting member 53 from the outer peripheral surface. More specifically, the winding drum 52 winds up the connecting member 53 when the opening/closing body 3 performs the opening operation, and feeds the connecting member 53 when the opening/closing body 3 performs the closing operation.

The connecting member 53 has one end attached to the outer peripheral surface of the winding drum 52 and the other end attached to the lower end portion of the opening/closing body 3 . Note that the connecting member 53 may be any member that can be wound around the winding drum 52, and may be, for example, a chain or chain made of metal, or a substantially cord-like or substantially belt-like member made of a material other than metal. .

The torsion spring is provided so as to bias the rotating shaft 51 in the direction in which the connecting member 53 is wound.
In other words, the urging member 54 has a function of assisting the opening operation of the opening/closing body 3 by the operator, and when the opening/closing body 3 is fully opened, the urging member 54 pushes the opening/closing body 3 positioned on the upper guide part 43 toward the upper guide part 43 . It has the function of detaining on top.

When the operator lifts the opening/closing body 3 in the closed state and performs an opening operation to open the opening 2, the panel positioned at the top of the opening/closing body 3 is sequentially moved to the upper guide part 43 so as to bend one by one. . As the opening operation continues, the opening/closing member 3 moves to the upper guide portion 43 and the opening 2 is fully opened.
On the other hand, when the opening 2 is to be closed, the operator pulls downward an operation part such as a hanging string (not shown) attached to the lower panel, thereby pulling down the opening/closing body 3 along the vertical guide part 41. take action. When the opening/closing body 3 is closed, the panel positioned on the opening 2 side among the panels on the upper guide portion 43 is sequentially moved to the vertical guide portion 41 . As the closing operation continues, 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 bottom comes into contact with the lower end of the opening such as the floor surface or the ground. By doing so, the opening 2 is fully closed.

In the above description, as the opening/closing mechanism 5, an opening/closing mechanism of a type in which an operator manually opens/closes the opening/closing body 3 is exemplified. A configuration including an opening/closing mechanism that rotates the rotating shaft 51 by a driving source such as a motor (not shown) may be employed.

According to the embodiment, since the upper reinforcement 20 and the reinforcement collapse prevention means 60 for preventing the collapse of the lower reinforcement 21 are provided, the panel due to the collapse of the upper reinforcement 20 and the lower reinforcement 21 is provided. It is possible to provide the opening/closing device 1 that can prevent the deformation of the panel and prevent the deterioration of the wind pressure resistance strength of the panel.

In addition, since the lower panel 10B includes the central reinforcing member 23, the bending strength of the panel body is improved when the lower panel 10B collides with the ground when the opening/closing member 3 is closed.

In addition, since the opening/closing body 3 in the closed state is configured to include the lower reinforcing body 21 between the vertically adjacent panels, the wind pressure resistance strength of the entire opening/closing body 3 set in the closed state is increased. We can make it big.

Further, the upper reinforcing body 20, the lower reinforcing bodies 21 and 22, and the central reinforcing body 23 protrude from the surface of the panel on the one region 6 side, and extend in the left-right direction of the panel corresponding to the width direction of the opening 2 and in one side. Since it is provided so as to extend to the region 6, the wind pressure resistance strength of the opening/closing body 3 against the wind pressure from the other region across the opening 2 can be further improved.

Further, since the upper reinforcing body 20 and the lower reinforcing body 21 of the upper panel 10A and the lower reinforcing body 21 of the intermediate panel 10C are made of hollow material, the material cost can be reduced and the reinforcing body of high strength is provided.
