The loading/unloading side wall 100 is inclined parallel to the loading/unloading guide hanging wall 87 of the block body 84 used as the block body 84 and the forward protruding guide wall 88 following this, The width of the gap is slightly larger than that of the slave guide 10 made of rollers.

The rear part of the short side part 99 slightly protrudes below the slave guide rail part 61, and the lower edge of this protruding part 101 has a slope such that the end in the folding direction is low and the end in the fully closing direction is high. This is a surface portion 102.

Next, the operation of the present invention will be explained.

When the lead panel 1a on the intervening side is moved in the direction of the arrow A in FIG. 15A, the slave guide 10 located at the end in the folding direction (on the right side in FIG. 15) is moved to the first kickout, as shown in FIG. 15S. It rides on the loading/unloading slope 86 of the block body 84 used as the block 12, is guided by the loading/unloading guide hanging wall 81, and jumps forward along the front projecting wall 88.

When the left lead panel 1a is further moved in the direction of arrow A in FIG.
Inclined surface 8 for loading and unloading the block body 84 used as
6, is guided by the loading/unloading guide hanging wall 81, and jumps forward along the forward protruding guide wall 88, and in the same way, the third slave guide 10, the fourth slave guide 10, etc.
. . . are projected outward one after another, and then folded to the fully open state as shown in Fig. 15d.

On the other hand, when changing from the fully open state to the fully closed state, Fig. 15 d
The fully closing operation is performed by pulling the lead panel 1a on the fully closing direction side in the direction of the arrow, and when the lead panel 1a is pulled in the direction of the arrow in Fig. 15 d, the follower on the end side on the fully closing side The guide 10 is connected to the side wall 100 for loading and unloading of the inclined long side portion 98 of the secondary kicking block 13b of the second kicking block 13.
is guided by this and pushed downward by the guiding inclined piece 91 as shown in FIG. Enter into the guide rule part 61,
Here, the slave guide 10 is pushed upward by the spring force of the spring 11 within the slave guide rail part 61, so that it does not escape from the guide rail part 61 (moves in the fully closed direction).

At this time, since the peripheral edge of the upper surface of the slave guide 10 is an inclined surface part 51, as shown in FIG. It can be smoothly inserted into the underside of the.

Similarly, the second slave guide 10 from the end in the fully closed direction.
The third slave guide 10 is guided by the subsidiary kicking block 13b one after another, and the guiding inclined piece 91
The slave guide 10 is pushed down, and the slave guide 10 goes into the slave guide guide rule part 61.Finally, the slave guide 10 at the end in the folding direction moves into the guiding inclined piece 97.
along the guide line 61, and is completely closed.

At this time, the slave guide 10 is not guided by the sub-extrusion block 13b, but directly enters the lower surface of the guide inclined piece 97 in the folding direction than the sub-extrusion block 13b, and enters into the slave guide rule portion 61. The slave guide 10 can be inserted into the slave guide rail 61 from any position on the upper rail 6, and there is no risk of a mistake in the closing operation of the folding door body 4. When it goes directly into the diameter guide rail part 61, when it is pulled in the fully closed direction, there will be a block body 84 in the middle, but in this case it will move along the slope 85 for riding on the block body 84. The slave guide 10 can pass under the block body 84, and at this time, the presence of the drop-preventing slope 89 and the drop-preventing hanging wall 90 allows the slave guide 10 to pass under the block body 84.
It is something that will not fall off in front of you.

As described above, in the present invention, the vertically movable secondary guide provided above the front hinge is spring-loaded upward, so that when the secondary guide is inside the upper rail, The slave guide does not jump out of the upper rail even if an external force is applied from the rear side when the folding door body is fully closed,
As a result, the front hinge part will not be folded open due to external force, and the fully closed state can be maintained accurately.Moreover, the inclined guide piece can be tilted outward from the upper rail. Since the secondary guide extends upward, even though the secondary guide is biased upward by a spring to accurately maintain the fully closed state of the folding door body, the secondary guide does not work properly when the folding door body is fully closed. The guide is pushed downward by the guide inclined piece and inserted into the upper rail, and the guide can be smoothly inserted into the upper rail without any hindrance.

Furthermore, since the slave guide is biased upward by a spring, even if there is a slight error in the height of the upper rail, this error can be absorbed by the deformation of the spring, and it can be adjusted according to the site situation without any problems. The folding door body can be attached to the upper rail.
