The engaging / disengaging member 90 configured as described above can move in the passage opening width direction (left and right direction according to FIG. 2) by loosening the fastener. 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.

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. .

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.

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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.

  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.
