Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

(Example) FIG. 1 shows a folding door device. The folding door device is a folding door composed of a plurality of panels 1a, 1b ..., an upper rail 2, a lower rail 3, a hanging frame 4 and a door stop frame. 5 is attached to the frame body formed by 5, and FIG. Panels 1a, 1b ... are main joint 6 and kick-out joint 7
A running tool 8 that is flexibly connected through the main joint portion 6 and hangs the panel 1 and moves the upper rail 2 on the upper end of the main joint portion 6,
A main slider 9 is provided at the lower end to move while being restrained by the lower rail 3. On the other hand, an upper latch 10 projects from the upper end of the kick-out joint portion 7, and a lower latch 11 projects from the lower end. And
Kick-out cams 21 are provided at the upper ends of every other panel 1a, 1c ...
However, the kick-out block 1 that engages with the kick-out cam 21 again
6 and 16 are fixed at appropriate positions on the upper rail 2. As is well known, the running tool 8 does not come off from the upper rail 2, but the kick-out joint portion 7 releases the upper and lower latches 10 and 11 from the guides of the rails so that the upper and lower rails 2 and 3 can be released. It is kicked out of and the folding door is folded. As will be described later, the upper and lower latches 10 and 11 are released, and the upper latch 10 is pushed down and the lower latch 11 is kicked out while being pushed up. The kicking-out joint portion 7 is kicked out by engaging a kicking-out block 16 arranged on the upper rail 2 and a kicking-out cam 21 fixed to the upper end of the panel.

FIG. 2 shows a cross section in which the upper rail 2 and the upper latch 10 are attached, but the panel 1 is suspended by the traveling tool 8 attached to the upper end of the main joint portion 6, and the traveling tool 8 is attached.
Can travel along the rail piece 12 of the upper rail 2 in the longitudinal direction. A guide piece 13 extends downward on the rail piece 12 on one side, and a tight material 14 having an airtight function is attached to the inside of the lower end of the guide piece 13.
It is installed alongside and guides the inner side surface 15 of the panels 1a, 1b ... And also prevents wind and rainwater from entering from above. A kick-out block 16 is fixed at a predetermined position inside the guide piece 13, and a latch receiver 17 is formed on the other rail piece 12 along the longitudinal direction. However, the latch receiver 17 is not long enough to reach the side surface of the panel 1 like the guide piece 13 and has a slight gap between the upper end 18 of the panel and is pushed down inside the latch receiver 17. The block 19 is fixed at a predetermined position, and the lower end surface of the push-down block 19 is the same as or slightly protrudes from the lower end surface of the latch receiver 17. The upper latch 10 projects from the upper end 18 of the panel 1, and the tip of the upper latch 10 forms a triangle inclined inward and is attached in a vertically movable state. That is, the upper latch 10
Is constantly lifted by the spring 20 built in the upper part of the panel 1, and moves down when the panel 1 moves along the rail and engages the push-down block 19, and the tip of the upper latch 10 is at the same position as the lower end surface of the latch receiver 17 Can be pushed down to. Further, in this state, the kick-out cam 21, which will be described later, comes into contact with the above-mentioned kick-out block 16 so that the upper latch 10 passes through the latch receiver 17 and is kicked out of the rail, and the panel 1 is bent and folded. .

FIG. 3 shows a cross section of a position where the kick-out cam 21 is attached. The kick-out cam 21 is pivotally supported on the upper end of the panel 1 through a shaft 22 and rotates only in a fixed direction. Is allowed.

As shown in FIG. , 24 almost coincide with each other. Of course, there is no necessity that the slopes 23 and 24 as shown in the figure must be used, and it is sufficient to form them with a smooth arc. And
Such a kick-out cam 21 moves in the direction of the arrow when folded together with the panel 1, and the upper latch 10 is pushed down by the push-down block 19, and at the same time, the kick-out cam 21 contacts the kick-out block 16. If it is further moved in the direction of the arrow (longitudinal direction of the rail), the kick-out cam 21 must move in the direction perpendicular to the moving direction of the arrow. That is, the panel 1 is kicked out of the upper rail 2 and folded. Since the kick-out cam 21 is prevented from rotating counterclockwise from the state shown in FIG. 4, the panel 1 can be kicked out, but when the folded panels 1a, 1b ... The kick-out cam 21 hits the kick-out block 16 on the opposite slope 23, and in this case, the kick-out cam 21 rotates clockwise and escapes as shown in FIG. In the state where the panels 1a, 1b ... Are folded, the upper latch 10 is outside the upper rail 2 and the latch receiver 17, but if the folding door is extended, the upper latch 10 will be inclined with its tip facing inward. Since the slope 25 is formed, the slope 25 is pushed down against the latch receiver 17 and guided into the latch receiver 17. The kicking cam 21 that has once entered the upper rail 2 moves in the upper rail 2 by rotating and escaping as shown in FIG.
10 is also pushed down by the push-down block 19 to move. Therefore, the shape of the push-down block 19 is
In order to push down 10, it is necessary to incline with respect to the longitudinal direction of the upper rail 2, so that the kick-out cam 21 can return to the original state (state of FIG. 4) after rotating clockwise. A torsion spring (not shown) is attached to the shaft 22. However, the panel 1a on the hanging side and the panel located on the sliding door side
The kick-out cam 21 attached to 1e does not necessarily have to be allowed to rotate.

By the way, the latch receiver 17 is formed over the entire length of the upper rail 2, and the upper latch 10 which engages / disengages with the latch receiver 17 is not attached to the kick-out joint portion 7 and the upper latch 10 is provided on the suspension side.
