A folding state holding device for holding a door in a folded state constituted by an actuator 55 fixed near the tip of the support string 54, the first
As shown in Figure 0, the actuator 55 enters the storage case 53 in the folded state and is locked by a locking piece (not shown) provided inside the case 53. . When the door is moved in the closing direction with a force above a certain level, the actuator 55 is disengaged from the locking piece and the locked state is released, allowing the door to be closed.

Next, the operation of the double folding door constructed as described above will be explained.

1 and 3 show the door in its closed state. Now, when you grasp the handle 56 fixed to the rightmost support connection frame 5 and move the entire door in the direction of opening (arrow P), the leftmost push rod 31 first hits the inside surface of the vertical frame 1. When the push rod 31 is moved a distance after contact, the head 31a of the push rod 31 is relatively protruded from the auxiliary panels 6, 7 in the direction of the arrow P.
As a result, the leftmost actuating plate 28 is pushed in the same direction, and the main panels 16 and 17 are moved around the shaft 29 through the stopper 30 against the tensile forces of the actuating strings 46 and 50 and the tension spring 49. It is rotated outward, and only the leftmost double folding frame 11 is folded into a diamond shape as shown in FIG.

After the double folding frame 11 is deformed into a substantially rhombic shape as shown in FIG. 9 and subjected to the initial folding operation, the actuating plate 28 is not rotated because the pushing rod 31 is stopped. Heavy folding frame 1
1 is folded under the force of opening, and the stopper 30 is separated from the actuating plate 28.

When the leftmost double folding frame 11 is completely folded, the second support connecting frame 5 from the left is opened.
The left end of the push rod 31 attached to the left side contacts the push plate 35 provided on the leftmost support connection frame 5, and the main panels 16, 17 are rotated outwardly around the shaft 29 by the push rod 31. The heavy folding frame 11 is folded into a substantially diamond shape.

When the second folding frame 11 from the left is completely folded, the last folding frame 11 is folded by the action described above, and when all the folding frames 11 are completely folded as shown in FIG. The actuator 55 is inserted and locked in the storage case 53 of the folded state holding device 52,
The door is thus held open.

Now, in the embodiment of the present invention, the mounting plate 2 is attached to the main panels 16 and 17 of the double folding frame 11.
An actuation plate 28 that provides an initial folding action to the double folding frame 11 via a shaft 29 is rotatably supported by a shaft 29, and a stopper 30 is fixed to the mounting plate 26 to connect the main panels 16, 17 and the actuation plate. 28
Since the angle α with the double folding frame 11 is completely folded, it is possible to move the actuating plate 28 away from the stopper 30 and increase the angle α. , the double folding frame 11 can be folded compactly by reducing the interval between adjacent support connecting frames 5.

Further, in the embodiment of the present invention, since the actuating plate 28 is rotatably supported, interference between the actuating plate 28 and the auxiliary panels 6 and 7 can be avoided in the fully folded state shown in FIG. There is no need to make a diagonal notch in the inner corner of the hole 7, and the manufacturing process can be made that much easier.

In the above embodiment, the stopper 30 was provided around the shaft 29, but the stopper 30 was omitted and various modifications were made, such as forming a stopper 26a at the joint between the mounting plate 26 and the actuating plate 28 as shown in FIG. Possible stopping means are:

As described above in detail, the present invention includes attaching an actuating plate capable of imparting the initial folding operation of the double folding frame to the inner surface of the main panel so as to be horizontally rotatable and close to the hinge; The initial folding motion of the actuating plate is transmitted to the main panel between the main panel and the actuating plate, and the auxiliary panel and the main panel are brought into a substantially parallel state when the double folding wall or door is closed. A stop means such as a stopper that can be held is provided between the auxiliary panels, and a pushing rod that can push the actuating plate by coming into contact with a wall surface or a pressing plate attached to the auxiliary panel is provided between the auxiliary panels to reciprocate in an approximately horizontal direction. By attaching it movably, there are the following effects. In other words, the door can be made compact when folded, the main panel on the wall side can be folded sequentially and used in a half-open state, and safety during opening and closing operations is increased. Since there is no need to cut out the support connection frame side, there is an advantage that manufacturing can be performed much more easily.
