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
And approaches the stopper member 7 at the same time as the doors 1, 2
Is the folding position. At that time, the lever piece 42 of the lever member 40
Collides with the stopper member 7. That is, the contact portion of the lever 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 right lever piece 42 is pushed into the straight groove 24a,
The pressing piece 44 advances and the taper surface 45 causes the taper receiving surface 47 to spring 32.
Since it is pushed down against, the latch 31 retracts from the engagement receiving hole 26 and is in the disengaged state. 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 embodiment, the guide member 10 and the arm member 11
The fixing member 12 has been described above, but it is merely an example, and each member having an equivalent function such as the structure of the wheels 21 and 22 can be implemented. Further, although the example in which the pivot device 6 is provided on the outer frame side of the main body side A is illustrated and described, it is possible to run another runner member 5 instead of the pivot device 6. In this case,
If the arm member 11 of another runner member 5 is set short,
Both doors 1 and 2 can be stored in parallel and separated positions. Further, 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. [Advantages of the Invention] As described above, the runner member according to the present invention has a guide member that travels on a rail member and a base end that is connected to this guide member so that it can always travel in an overlapping manner, and from the door folding position. An arm member whose tip is connected so as to be horizontally rotatable, a fixing member attached to the tip of the arm member and fixed to the door, and an adjustment provided between the arm member and the fixing member for adjusting a door attachment position By configuring with the mechanism, it was possible to shift the door from the conventional folding position to the substantially parallel storage position without opening a special device, and to fully open the frontage. Also, since the runner member can swivel and the door mounting position can be adjusted, if it is incorporated into the conventional folding door structure,
There is an advantage that it can be changed to a fully open structure.
