The operation based on the above configuration will be described.

Here, in the folding door device, the runner member 5 is at an intermediate position of the rail member 4 and the doors 1 and 2 are parallel to each other at the door closed position. In such a state, between the guide member 10 and the arm member 11, the latch 31 is projectingly engaged with the engagement receiving hole 26 to be in the engaged state, and the members 10 and 11 are overlapped in the longitudinal direction. It is in one state. Further, the lever piece 42 of the lever member 40 is movably protruded on the lower surface of the lever member 4 toward the folding side.

As the door is folded, the runner member 5 runs on the rail member 4 and approaches the stopper member 7, and at the same time, the doors 1 and 2 are in the folding position. At that time, the lever piece 42 of the lever member 40 abuts the stopper member 7. That is, the contact portion of the lever piece 42
As the lever piece 42 is pushed against the spring 41 as the stopper piece 8 abuts against the stopper piece 8, the lever piece 42 is engaged with the straight groove 24a of the substrate cam groove 24.

When the lever piece 42 is pushed into the linear groove 24a, the pushing piece 44 moves forward and the tapered surface 45 pushes down the tapered receiving surface 47 against the spring 32, so that the latch 31 retracts from the engagement receiving hole 26. The engagement is released.

Therefore, when the inner frame sides of the doors 1 and 2 are pushed to give a turning force toward the main body A, the other end 30b of the arm member 11 turns about the pin 23 as a fulcrum. Along with the turning, the lever piece 42 shifts from the straight groove 24a to the turning restriction groove 24b and turns, and the turning is restricted at the groove end. In this case, since the arm member 11 is configured to be rotatable about 90 degrees, the arm member 11 is
Is orthogonal to. Since the door 2 is positioned with the fixing member 12 with respect to the arm member 11, both doors 1 and 2 are separated from the rail member 4 and housed along the main body A in a substantially parallel state. Of course, the frontage is fully open.

When closing the doors, if a swinging force is applied to the folding positions of the doors 1 and 2 in the opposite direction to the previous time, the arm member 11 swings and the lever piece is rotated.
42 shifts from the rotation restricting groove 24b to the straight groove 24a, and the bumper member 34 comes into contact with the detent piece 27 to be in a straight line state. In such a state, the latch 31 faces the lower part of the engagement receiving hole 26, so that if the lever piece 42 is separated from the stopper piece 8 by pushing the doors 1 and 2 from the folded position to the closing direction, the lever Since the piece 42 retracts from the linear groove 24a by the spring 41,
The push-down piece 44 retracts to raise the latch 31 and enter the engaged state.

When adjusting the mounting position of the door, turn the door 1 and 2 to the open state and swivel outside the frontage in a direction substantially parallel to the rail member 4,
This can be done with the other end 30b of the arm member 11 positioned in front of the frontage.

In this case, loosen the fixing screw 61 and move the adjustment plate 60 along the long hole 62.
Move up and down. The fixing screw 61 is tightened and positioned at a position where traveling and turning are not hindered.

Similarly, loosen the fixing screw 70 and move the hinge piece 51 along the long hole 71.
Move in the front-back direction, and tighten the fixing screw 70 at an appropriate position for positioning.

[Advantages of the Invention] As described above, according to the present invention, since the rail member does not have a complicated structure and the mounting work is easy, the manufacturing cost can be reduced.

Further, since the arm member is rotated with respect to the guide member when the door is rotated, the movement of the guide member in the rail member is not forcibly affected. Therefore, even when the door is folded or swung rapidly. This has the effect of preventing damage to rail members and guide members. Further, due to this effect, the smoothness of the movement of the guide member in the rail member is maintained.

Furthermore, since the adjusting means can easily adjust both the front-rear direction and the vertical mounting position of the door at one position on the other end side of the arm member, the defective mounting position of the door can be eliminated and the door The effect is that folding and turning can always be performed accurately.
