The operation based on the above configuration will be described. 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, the guide member 10 and the arm member
Between 11 and 11, the latch 31 projects into the engagement receiving hole 26 and is in an engaged state, and the two members 10 and 11 are in an integrated state in which they are superposed in the longitudinal direction. Also, the lever piece of the lever member 40
42 is a lower surface of the rail member 4 and is movably projected toward the folding side. As the door is folded, the runner member 5 becomes the rail member 4
When the vehicle runs and approaches the stopper member 7, the door 1
2 is the folding position. At that time, the lever piece 4 of the lever member 40
2 collides with the stopper member 7. That is, as the abutting portion 43 of the lever piece 42 abuts the stopper piece 8,
Since the lever 42 is pushed against the spring 41, the lever piece 42 comes into a state of being engaged with the linear groove 24a of the substrate cam groove 24. When the right lever piece 42 is pushed into the straight groove 24a, the pushing piece 44 advances and the tapered surface 45 pushes down the tapered receiving surface 47 against the spring 32, so that the latch 31 retracts from the engaging 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 arm member 11 turns the free end 20b with 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, the arm member 11 is orthogonal to the guide member 10 because it is rotatable about 90 degrees. Since the fixing member 12 is positioned on the door 2 with respect to the arm member 11, both doors 1, 2
Are stored along the main body A in a substantially parallel state apart from the rail member 4. Of course, the frontage is fully open. At the time of closing the door, if the swing force is applied to the doors 1 and 2 in the folding position in the opposite direction to the previous time, the arm member 11 swings and the lever piece 42 moves from the rotation restricting groove 24b to the straight groove 24a, The bumper member 34 comes into contact with the anti-rotation 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 is retracted from the linear groove 24a by the spring 41, the pressing piece 44 is retracted to raise the latch 31 and enter the engaged state. In the above-described embodiment, the example in which the pivot device 6 is provided on the outer frame side of the main body side has been illustrated and described, but the runner member 5 may be run instead of the pivot device 6. In this case, if the arm member 11 of the runner member on the main body side is set to be short, both doors 1 and 2 can be housed in parallel separated positions. Moreover, although the two-sheet suspended folding structure has been illustrated, it can be applied to a plurality of sets and the application to the lower runner member is not hindered. [Effects of the Invention] As described above, according to the folding door device of the present invention, the folding door device is engaged at the closed position and superposed and held on the folding door, and disengaged at the folding position and swung to the outer hardness. By using the runner member that is separated from the rail member, the door can be moved from the conventional folding position to the substantially parallel storage position, and the frontage can be fully opened, and the structure at that time can be simplified. did it.
