The opening / closing target opening 2 having the locked plate 5
The floor surface 4 has a protruding corner step 4 a outside the recessed locked portion 9.
The operation surface 10 of the locked plate 5 is provided from the raised corner step 4a of the opening floor surface 4 to the lateral side position of the recessed locked portion 9 of the locked plate 5. The operating body 11 at the protruding position is retracted by the protruding corner-shaped operation surface 10a that covers the protruding corner step 4a.
The operating surface 1 of the locked plate 5 is provided at the lower end of the operating body 11.
0, a slope 11a is formed so as to ride on the operation surface 10 from the corner-shaped operation surface 10a.

According to the restraining device having the above structure, when the door body 1 is located outside the opening 2, the operating body 11 is moved from the lower end of the door body 4 by the spring 12 as shown in FIGS. It is biased and held at the projecting position that projects downward,
As shown in FIGS. 1 and 3, the locking body 6 is in a state of being lifted by the elevating body 13 to a retreat position where the lower end locking portion 6 a does not protrude from the lower end of the door body 4. Thus, when the door main body 1 is closed, immediately before the door main body 1 enters the opening / closing target opening 2 (immediately before reaching the closing position for closing the opening 2), as shown in FIG. Slope 11
a is a corner-shaped operation surface 10 on the operation surface 10 of the locked plate 5;
a with the operating body 1 following the movement of the door body 1 thereafter.
The lower end slope 11 a of the first member 1 rides on the operation surface 10 of the locked plate 5, and the operation body 11 rises against the urging force of the spring 12.

As the operating body 11 rises, the rack gear 1
5, the elevating body 13 descends via the pinion gear 17 and the rack gear 16, and the descending movement of the elevating body 13 pushes down the locking body 6 via the spring 14, but the locking body 6 is still covered. Since the locking plate 5 does not reach the position facing the recessed locked portion 9, the lower locking portion 6 a of the locking body 6 is placed on the flat surface of the locked plate 5 as shown in FIG. In the abutted state, the recessed locked portion 9 is moved with the movement of the door body 1.
Will move towards. During this time, spring 1
Only 4 is compressed between the locking body 6 and the elevating body 13 to urge the locking body 6 downward.

When the door body 1 reaches the closed position for closing the opening 2, the locking member 6 reaches just above the recessed locked portion 9 of the locked plate 5, and the locking member 6 is 14 and is lowered by the urging force of the lower end 14 as shown in FIGS.
Are fitted into the recessed locked portions 9. The lower end of the operating body 11 remains pressed against the operating surface 10 of the locked plate 5 by the biasing force of the spring 12. As a result of the lower end locking portion 6a of the locking body 6 being fitted into the recessed locked portion 9 of the locked plate 5,
The movement of the door body 1 that has reached the closed position beyond the closed position to the inside of the opening / closing target opening 2 is performed by the vertical surface portion 9a of the recessed locked portion 9 and the lower end locking portion 6a of the locking body 6. Is prevented by abutment with the vertical surface portion.

When the door body 1 is opened from the closed position to open the opening 2 to be opened / closed, the recessed locked portion 9 of the locked plate 5 is moved as the door body 1 moves outward. The lower end locking portion 6a of the locking body 6 which has been fitted into the recessed portion 9 is pushed up against the urging force of the spring 14 by the slope portion 9b of the recessed locked portion 9. When the door body 1 moves to a position where the lower end of the operating body 11 is displaced outward from the operating surface 10 of the locked plate 5, the operating body 11 is lowered by the urging force of the spring 12 to the original projecting position. In conjunction with this, the lifting body 13 moves upward via the rack gear 15, the pinion gear 17, and the rack gear 16, and the lower end of the engagement groove 13a is
The locking body 6 is pulled up to the original retreat position via b.

Incidentally, the stopping device shown in the above embodiment can be provided at the upper end of the door main body, or can be provided at each of the upper and lower ends of the door main body.

[0017]

As described above, according to the folding device for a folding door or the like of the present invention, while the door body is stopped by the fixed door stop surface at the closing position that closes the opening to be opened and closed, When moved to the closed position, the locking body of the door body side automatically fits into the recessed locked portion of the locked plate attached below or above the opening / closing target opening, Since the door body is prevented from moving inward beyond the closing position, even if an external force is applied to press the door body inward, the door body is securely bent without inward bending. Can be held.

Moreover, it is not necessary to provide a projection protruding toward the opening on the locked plate attached below or above the opening to be opened / closed, but it is sufficient to provide a recessed locked portion. Therefore, the lower or upper side of the opening to be opened / closed can be made substantially flat, and there is no need to provide an overhang around the opening to receive the door body. Therefore, it is possible to maximize the size of the opening in which the door body is opened and closed, and in particular, articles that enter and exit from projections projecting from the lower floor plate surface or the upper top plate surface of the opening are caught. There is no inconvenience, and in the case of the walk-in type storage box, there is no danger that a person who gets in and out of the storage box will be stuck on the above-mentioned projection, particularly a projection provided on the floor plate surface, and the appearance will be improved. Further, the locking body can be driven reliably without using a magnet for the driving means of the locking body.

According to the configuration of the second aspect, not only can the ascent / descent movement of the operating body be reliably converted into the up / down movement of the locking body in the opposite direction, but also the small diameter as shown in the embodiment. By using a two-stage pinion gear having a pinion gear section and a large-diameter pinion gear section, the locking body is raised and lowered by the required amount while keeping the lifting and lowering amount of the operating body to the minimum necessary, and the expected operation is reliably performed. Can be done.
