For example, if the engagement / disengagement member 90 is moved and fixed to the closing direction side from the position shown in FIG. 2, the width of the passage opening when the opening / closing body 10 is fully opened can be reduced.

次に上記構成の吊戸装置1を現場の躯体開口部に装着する手順について説明する。
先ず、建築物等の躯体開口部に枠体20が装着され固定される。
そして、上枠部23の表面カバーを外した状態で、レール部材30のレール状突起31aに、開閉体10上端側の吊車40が嵌め合せられる。この際、吊車支持ブラケット50に対し、連結プレート56、被掛止部56a、取付ブラケット57、制動手段70の本体部71、及び被吸引体58等は予め固定されているが、外れ防止部材55は分離した状態である。
次に、吊車支持ブラケット50の開放方向側の補強部52に、外れ防止部材55が止着される。この際、外れ防止部材55は、切欠部55bによりレール状突起31aを囲むようにして装着される。
この組立方法によれば、吊車支持ブラケット50の切欠部55bとレール部材30のレール状突起31aとの隙間を比較的狭くできるので、吊車40の傾き及び脱輪等を効果的に防ぐことができる。
Next, a procedure for mounting the hanging door device 1 having the above-described structure on the chassis opening in the field will be described.
First, the frame 20 is mounted and fixed to a housing opening of a building or the like.
Then, the suspension wheel 40 on the upper end side of the opening / closing body 10 is fitted into the rail-shaped protrusion 31a of the rail member 30 with the surface cover of the upper frame portion 23 removed. At this time, the connecting plate 56, the hooked portion 56 a, the mounting bracket 57, the main body portion 71 of the braking means 70, the sucked body 58, and the like are fixed in advance to the suspension vehicle support bracket 50. Is a separated state.
Next, the disengagement prevention member 55 is fixed to the reinforcing portion 52 on the opening direction side of the suspension vehicle support bracket 50. At this time, the detachment preventing member 55 is mounted so as to surround the rail-shaped protrusion 31a by the notch 55b.
According to this assembling method, the gap between the notch 55b of the suspension vehicle support bracket 50 and the rail-shaped protrusion 31a of the rail member 30 can be made relatively narrow, so that the suspension vehicle 40 can be effectively prevented from being tilted and derailed. .

また、上記構成の吊戸装置1は、以下に示す作用効果を奏する。
開閉体10の全閉状態又は途中閉鎖状態等において、開閉体10に対し通路用開口部貫通方向の一方側から物体が当接したり、開閉体10が風圧等を受けたり等して、開閉体10及び該開閉体10上端側の吊車支持ブラケット50が傾き、その傾きが第1の所定角度α1となった場合には、先ず、図6(b)に示すように、レール部材30の下面にローラ54が当接することで、前記傾きが抑制される。
Moreover, the hanging door apparatus 1 of the said structure has an effect shown below.
When the opening / closing body 10 is in a fully closed state or a halfway closed state, the opening / closing body is brought into contact with the opening / closing body 10 from one side in the passage opening passage direction or the opening / closing body 10 receives wind pressure or the like. 10 and the suspension vehicle support bracket 50 on the upper end side of the opening / closing body 10 are inclined, and when the inclination becomes the first predetermined angle α1, first, as shown in FIG. The inclination is suppressed by the contact of the roller 54.

さらに、開閉体10が通路用開口部貫通方向の一方側から受ける力が大きく、ローラ54の基端側(軸支部分)が変形や破損等し、前記傾きが第2の所定角度α2となった場合には、図6(c)に示すように、吊車支持ブラケット50における外れ防止部材55の第四の内縁55b4が、レール部材30の下端面に当接することで、前記傾きが抑制されるとともに、吊車支持ブラケット50がレール部材30から脱落するようなことを防ぐことができる。
すなわち、例えば、傾いた吊車40がレール状突起31aから外れそうになったとしても、切欠部55bの第三の内縁55b3が、レール状突起31aの内側面に当たるため、吊車40の脱輪を防ぐことができる。
Further, the force received by the opening / closing body 10 from one side in the passage opening direction is large, the base end side (the shaft support portion) of the roller 54 is deformed or damaged, and the inclination becomes the second predetermined angle α2. In this case, as shown in FIG. 6C, the fourth inner edge 55b4 of the disengagement prevention member 55 in the suspension vehicle support bracket 50 abuts on the lower end surface of the rail member 30, so that the inclination is suppressed. At the same time, the suspension vehicle support bracket 50 can be prevented from falling off the rail member 30.
That is, for example, even if the inclined suspension wheel 40 is likely to come off from the rail-shaped protrusion 31a, the third inner edge 55b3 of the notch 55b hits the inner surface of the rail-shaped protrusion 31a, thereby preventing the suspension wheel 40 from being removed. be able to.

また、外れ防止部材55を、レール部材30の長手方向に対し直交させて吊車支持ブラケット50の補強部52に重ね合わせ固定しているため、該外れ防止部材55が前記当接の際の衝撃で変形したり外れたりするようなことを効果的に防ぐことができる。   In addition, since the detachment prevention member 55 is overlapped and fixed to the reinforcing portion 52 of the suspension vehicle support bracket 50 so as to be orthogonal to the longitudinal direction of the rail member 30, the detachment prevention member 55 is subjected to an impact at the time of contact. It is possible to effectively prevent deformation and disconnection.

また、開閉体10の閉鎖速度を変えるために、付勢手段60や制動手段70を調整する場合には、その調整作業を、通路用開口部側(図1の左側)から行うことができ、その作業性及びメンテナンス性が良好な上、開閉体10の閉鎖動作も付勢手段60による閉鎖方向側からの牽引によりスムーズに行われる。   Further, when adjusting the biasing means 60 and the braking means 70 in order to change the closing speed of the opening and closing body 10, the adjustment work can be performed from the passage opening side (left side in FIG. 1). The workability and maintainability are good, and the closing operation of the opening / closing body 10 is smoothly performed by pulling from the closing direction side by the biasing means 60.

また、閉鎖動作した際の開閉体10が、全閉位置を通り過ぎて、開口部交差方向へ回動してしまうようなことを、磁性吸引体80の吸引力により防ぐことができる。   Further, it is possible to prevent the magnetic attracting body 80 from causing the opening / closing body 10 when the closing operation is performed to pass through the fully closed position and rotate in the direction intersecting the opening.

また、製造時やメンテナンス時に、吊車支持ブラケット50に対し、制動手段70の本体部71や被吸引体58等を装着する作業は、制動手段70の本体部71、被吸引体58及び取付ブラケット57等を一体的に扱うことができ、その作業性が良好である。   Further, the work of mounting the main body 71 of the braking means 70, the sucked body 58, etc. to the suspended vehicle support bracket 50 during manufacturing or maintenance is performed by the main body 71 of the braking means 70, the sucked body 58, and the mounting bracket 57. Etc. can be handled integrally, and its workability is good.

また、制動手段70による減速開始位置を変えるために、ラック72を通路用開口部幅方向へずらす作業や、開閉体10の全開位置を変えるために係脱部材90を通路用開口部幅方向へずらす作業も、上述したラック72とレール部材30の嵌合構造、及び係脱部材90とレール部材30の嵌合構造によって容易に行うことができる。   Further, in order to change the deceleration start position by the braking means 70, the rack 72 is shifted in the passage opening width direction, and the engagement / disengagement member 90 is moved in the passage opening width direction in order to change the fully open position of the opening / closing body 10. The shifting operation can be easily performed by the above-described fitting structure between the rack 72 and the rail member 30 and the fitting structure between the engagement / disengagement member 90 and the rail member 30.

なお、上記実施例によれば、特に組立性及び強度的に良好な態様として、吊車支持ブラケット50に対し別体の平板状の外れ防止部材55を止着したが、他例としては、吊車支持ブラケット50に対し一体的に外れ防止部材を加工した構成や、外れ防止部材55をブロック状に形成した態様等とすることも可能である。   In addition, according to the said Example, as a mode with especially favorable assembly property and intensity | strength, although the separate flat plate-shaped removal prevention member 55 was fixed with respect to the suspension vehicle support bracket 50, as another example, a suspension vehicle support is carried out. It is also possible to adopt a configuration in which the detachment preventing member is integrally processed with respect to the bracket 50, an aspect in which the detachment preventing member 55 is formed in a block shape, or the like.

また、上記実施例によれば、特に好ましい態様として、ローラ54と外れ防止部材55の双方を設けたが、他例としては、ローラ54のみを省いた構成とすることも可能である。   Moreover, according to the said Example, although both the roller 54 and the separation | staining prevention member 55 were provided as a particularly preferable aspect, it can also be set as the structure which excluded only the roller 54 as another example.

また、上記実施例によれば、特に磁性吸引体80による作用を効果的に得る構成として、両開き式の折戸装置を構成したが、他例としては、片方開き式の折戸装置や、バランスドア、引戸等を構成することも可能である。   Moreover, according to the said Example, although the double-folding type folding door apparatus was comprised especially as a structure which obtains the effect | action by the magnetic attraction body 80 effectively, as another example, a one-side opening type folding door apparatus, a balance door, It is also possible to configure a sliding door or the like.
