1 and protrudes to the outside. As shown in FIG. 3, these protrusions are hidden by projecting edges 2a', 3a' of the front plates of the respective door bodies 2a, 3a.

The latch actuator 12 is similar to that in the door body 2a.
Rotating plates 17, 24 are pivoted to seat plates 14a, 23, 17', 24', respectively, to latch holding pieces 20, which are slidably fitted into guide frames 18 provided at the upper and lower ends of the cover plate 13. The front frame plate of the main body 1 is connected through a connecting member 25, etc., and the claw portion 19' at the tip of the L-shaped latch 19 attached to the latch holding piece 20 is resiliently repelled by the return spring 22 attached to the holding piece 20. Part 1'
The vertical arm 24a of the rotary plate 24 is engaged with the end surface of the holding piece 20 opposite to the return spring 22 to hold the door 3 in the closed position. In addition, the longitudinal arm 17a of the pivot plate 17 engages the vertical wall of the groove 12a in the latch actuator 12.

Since the door latch device of the present invention has the above-described structure, first, hold the operating edge of the latch actuator 12 with your finger inserted into the handle opening 16 of the right door body 2a.
2' is pushed outward (to the right) against the return spring 15.
The latch holding piece 20 moves to the right against the return spring 22 via the rotating plate 17, the connecting member 25, and the rotating plate 24, and the latch 19 is disengaged from the engagement hole 21 of the main body 1. If the door body 2a is pushed outward (to the right) while pulling it slightly forward, the door bodies 2a, 2b will be folded via the hinge 4 and opened to the right. (Figure 4). Furthermore, the pressing plate 29 of the door body 3a
When pushed to the left, the latch actuator 12 moves to the left against the return spring 15 through the connecting plates 27 and 28, and the latch holding piece 20 moves through the rotating plates 17 and 24, which are deflection members, and the connecting member 25. moves to the left against the spring 22, and the latch 19 disengages from the engagement hole 21 of the main body 1. If the door body 3a is pushed outward (to the left), the door body 3
a, 3b are folded via hinge 4' and opened to the left.

To close the door, for example, after moving each door body 2a, 3a toward the center, simply push the area near the hinge portion 4, 4' of each door body backward, and the inclined edge 19'' at the front end of each latch 19 will open. engages with each hole edge of the engagement hole 21 of the main body 1,
This causes the latch holding piece 20 to return to the spring 2
2, the inclined edge 19'' is removed from the hole edge and returned to its position by the return spring 22, so that the latch 19 is locked in each engagement hole 21.Thus, the door body 2a, 3
Since the inner end of the door a is moved laterally by rollers 8 and 9 to open and close, the door may be closed from either the left or right door.

The door opening/closing device of the present invention is configured as described above for each door body 2.
Since the opening direction of the latch a, 3a and the operating direction of the latch actuator 12 are almost the same, the latch can be unlocked and the door can be opened with a single operation, which is extremely convenient. In this case, it is more effective if the operating edge 12' of the latch actuator is located as close as possible to the inner edge of the door body. In addition, folding doors are convenient because they do not require a large space in front of the door to open and close, allowing the door to open wide.
When closed, the hinge may protrude forward and bend into a dogleg shape. However, in the present invention, as described above, latches are provided on both sides of the door to lock the door, so that it is possible to prevent the hinged portion from protruding on either side. In this case, it is more effective to provide the latch 19 near the hinged portions 4, 4'. In addition, if the latch 19 is provided, the hinge portions 4, 4' may be installed between the door body and the front frame of the main body as necessary.
If a spring or the like is provided to press forward, when the door is closed, the door can be closed by simply pushing the hinge parts 4, 4' backward against this spring, or by simply removing the latch 19. The hinge parts 4, 4' extend forward and become easier to bend, making it easier to open the door. In addition, in the illustrated embodiment, the pull opening 16 is provided only on one side of the door, similar to a normal double door, but this may be provided on both doors. In this case, each door can be opened separately. It is convenient.
