上述した開閉装置の開閉体を構成する各パネルは、パネルの一方の領域側の面における開閉体の開閉方向の一端縁(下端縁）側にのみ補強体を備えている。
しかしながら、各パネルの一方の領域側の面における開閉体の開閉方向の一端縁(下端縁）側にのみ補強体を備えた構成の開閉体では、開口を閉鎖する閉鎖状態の開閉体に、開口を隔てた他方の領域側からの風圧に対する耐風圧強度が低いという課題があった。
特に、開口を隔てた他方の領域側から閉鎖状態の開閉体に加わる風の力は、既知の風圧力の式により、地面から高い位置になるほど強くなるため、上述した従来の開閉体の閉鎖状態において最も上側に位置するパネルは、他方の領域側からの風圧に対する耐風圧強度が低くなってしまうという課題があった。 Each panel constituting the opening/closing body of the opening/closing device described above has a reinforcing member only on one edge (lower edge) side in the opening/closing direction of the panel on one region side.
However, in an opening/closing body having a structure in which a reinforcing member is provided only on one edge (lower edge) in the opening/closing direction of the opening/closing body on one area side surface of each panel, the opening/closing body in the closed state for closing the opening has an opening. There was a problem that the wind pressure resistance strength against the wind pressure from the other side of the area was low.

図１に示すように、開閉機構５は、例えば、開口２の上方において開口２の幅方向に亘って配設される回転軸５１と、回転軸５１の両端部に固着される一対の巻取ドラム５２，５２と、一端が巻取ドラム５２に連結されて他端が開閉体３に連結され、回転軸５１が回転することによって巻取ドラム５２に巻き取られたり巻取ドラム５２から繰り出される、例えば金属製のワイヤー等の連結部材５３と、連結部材５３を巻取ドラム５２で巻き取る方向、即ち、開閉体３を開放する方向に、回転軸５１を付勢する付勢部材５４とを備える。 As shown in FIG. 1 , the opening/closing mechanism 5 includes, for example, a rotating shaft 51 disposed above the opening 2 across the width of the opening 2 and a pair of winders fixed to both ends of the rotating shaft 51 . The drums 52, 52 are connected at one end to the winding drum 52 and at the other end to the opening/closing body 3, and are wound up on and unwound from the winding drum 52 by the rotation of the rotating shaft 51. A connecting member 53 such as a metal wire, for example, and a biasing member 54 for biasing the rotation shaft 51 in the direction in which the connecting member 53 is wound by the winding drum 52, that is, in the direction in which the opening/closing body 3 is opened. Prepare.

回転軸５１は、中空又は中実の軸体であって、一対のガイド手段４，４が離間する距離と略等しい長さを有し、開口２の上端よりも上方において開口２の幅方向に延長して配設される。回転軸５１は、躯体７に取付けられた複数の軸受けブラケット５６，５６…により回転可能に支持される。 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, . . .

巻取ドラム５２は、連結部材５３の巻き取りや繰り出しを可能とするボビン状（筒状）の部材であって、当該巻取ドラム５２の中心軸と回転軸５１の中心軸とが同心となるように回転軸５１の両端部に固定される。
巻取ドラム５２は、回転軸５１とともに回転することにより、連結部材５３を外周面上に巻き取ったり、連結部材５３が外周面上から繰り出す部材である。より詳細には、巻取ドラム５２は、開閉体３が開放動作する際に連結部材５３を巻取り、開閉体３が閉鎖動作する際に連結部材５３を繰出す。 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.

連結部材５３は、一端が巻取ドラム５２の外周面に止着され、他端が開閉体３の下端部に止着される。なお、連結部材５３は、巻取ドラム５２に巻き取り可能な部材であればよく、例えば、金属製の鎖やチェーン、金属以外の材質の略紐状あるいは略帯状の部材等であっても良い。 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. .

付勢部材５４としては、例えば、ねじりばね（トーションスプリング）が使用される。回転軸５１を当該ねじりばねの中空筒部に通した後、ねじりばねの一端部が回転軸５１の外周面に止着され、ねじりばねの他端部が躯体７に止着されている。
当該ねじりばねは、連結部材５３を巻き取る方向に回転軸５１を付勢するように設けられている。
つまり、付勢部材５４は、操作者による開閉体３の開放動作をアシストする機能を有するとともに、開閉体３を全開した状態において、上側案内部４３上に位置する開閉体３を上側案内部４３上で留置く機能を有する。 A torsion spring, for example, is used as the biasing member 54 . After passing the rotating shaft 51 through the hollow cylindrical portion of the torsion spring, one end of the torsion spring is attached to the outer peripheral surface of the rotating shaft 51 and the other end of the torsion spring is attached to the frame 7 .
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.

操作者が、閉鎖状態の開閉体３を持ち上げて開口２を開放する開放動作を行うことにより、開閉体３の最上部に位置するパネルから一枚ずつ折れ曲がるように上側案内部４３に順次移動する。そして、開放動作が継続することにより、開閉体３が上側案内部４３に移動し、開口２が全開される。
一方、開口２を閉鎖する際には、操作者が、下パネル１０Ｂの取り付けられた図外の下げ紐等の操作部を下方に引張ることにより、開閉体３を垂直案内部４１に沿って引き下げる閉鎖動作を行う。開閉体３を閉鎖動作させると上側案内部４３上の複数のパネルのうち、開口２側に位置するパネルから垂直案内部４１に順次移動する。そして、閉鎖動作が継続することにより、開閉体３が垂直案内部４１に移動し、最下部に位置する下パネル１０Ｂの下端に設けられた水切りシール２５が床面、地面等の開口下端と接触することにより開口２が全閉される。 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 operating portion such as a hanging string (not shown) attached to the lower panel 10B, thereby pulling down the opening/closing member 3 along the vertical guide portion 41. Perform closing 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.

なお、上記では、開閉機構５として、操作者が開閉体３の開閉を手動で行うタイプの開閉機構を例示したが、図外のチェーンホイスト機構を介して回転軸５１を回転させる開閉機構や、図外のモーター等の駆動源により回転軸５１を回転させる開閉機構を備えた構成であってもよい。 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 rotary shaft 51 by a driving source such as a motor (not shown) may be employed.

実施形態によれば、開閉体３は、上パネル１０Ａが、一方の領域６側の面における上端縁側において、パネルの左右方向Ｗ及び一方の領域６に延長するように設けられた上側補強体２０を備えているので、開閉体３が閉鎖状態に設定された場合に、他方の領域側から開閉体３に加わる風の力が一番強くなる開閉体３の上端側の部分の強度が大きくなる。
即ち、閉鎖状態に設定された開閉体３の上端側の部分の耐風圧強度を大きくできる。
従って、他方の領域側からの風圧に対する耐風圧強度を向上させた開閉体３を備えた開閉装置１を提供できるようになる。 According to the embodiment, the opening/closing body 3 includes an upper reinforcing body 20 provided so as to extend in the left-right direction W of the panel and in the one region 6 on the upper edge side of the surface on the one region 6 side of the upper panel 10A. Therefore, when the opening/closing body 3 is set to the closed state, the strength of the upper end side portion of the opening/closing body 3 where the wind force applied to the opening/closing body 3 from the other region side is the strongest becomes large. .
That is, the wind pressure resistance strength of the upper end side portion of the opening/closing body 3 set in the closed state can be increased.
Therefore, it is possible to provide the opening/closing device 1 having the opening/closing member 3 with improved resistance to wind pressure from the other area.
