A latching / retracting mechanism which can be detached, 6 and 7 are vertical wooden handles attached to the door surface material 2a in the toilet room 9, 8 is a vertical wooden handle attached to the door surface material 2a on the corridor 10 side, and 9 is a toilet. Room 10 is a corridor, and 11 is a room wall. In this embodiment, when the door is closed, as shown in FIG. 1, the door body 2 closes the opening of the three-door frame 1, and the rubber 2f per door of the door body 2 has three doors. It comes into contact with the frame 1 and serves as a buffer when the door is closed, so that the door closing sound is reduced. When the door is closed, the suspension shaft 2b and the horizontal body 3 of the door body 2 are located right and left from the center of the horizontal frame 1a. The own weight of the door body 2 is supported by the upper pin connecting portion 4e of the upper arm 4c and the lower pin connecting portion 4g of the lower arm 4d, and the center of gravity of the door body 2 is At the center of the door body, and is supported by the left and right suspension shafts 2b and the upper and lower pin connecting portions 4e and 4g. No longer excessively acting on No.4, it became strong, durable and could be opened and closed smoothly. Next, when the door is opened, the door main body 2 is pressed by hand, and the door main body 2 is rotated around the suspension shaft 2b which suspends the door. The rotation of the door body 2 causes the hinge body 4a to move the hinge body 4a between the pivot point at one end of the hinge body 4a and the upper pin connection 4e at the tip of the upper arm 4c or the lower pin connection 4g at the tip of the lower arm 4d. Since the door body 2 is restrained by the upper arm 4c and the lower arm 4d so that the length is constant, the door body 2 rotates so as to satisfy the condition, and the wheels 3c of the transverse body 3 move in the direction of the hinge 4 side. Rolling along the rail 1c of the V-shaped cross section of the horizontal frame 1a, the horizontal body 3 and the door body 2 connected to the horizontal body 3 via the hanging shaft 2b move along the rail 1c of the horizontal frame 1a. When the door body 2 is rotated by approximately 90 °, the horizontal body 3 and the suspension shaft 2b move to the vicinity of one of the vertical frames 1b as shown by the imaginary line in FIG. 4, and the door body 2 is substantially parallel along the passage wall. And the door is open. In this way, the door body 2 moves in one direction while being rotated around the suspension shaft 2b by being pushed, and the door body 2 retreats from the front of the surface operated by the pedestrian. In this way, the pedestrian can go straight through the door without moving its position to the left or right. The force of pressing against the door body 2 is received by the lateral wheel contact plate 1d when the lateral wheel 3f contacts the lateral wheel contact plate 1d of the lateral frame 1a. In addition, since the ball bearing is used for the suspension shaft 2b of the door body 2 and the bearings of the upper and lower pin connecting portions 4e and 4g, the rotation and movement of the door body 2 are smooth. When the door body 2 is near the closed state or the open state, the horizontal body 3 approaches the vertical frame 1b, the pinion gear 3d of the horizontal body 3 meshes with the racks 1f, 1g of the horizontal frame 1a, and the pinion gear 3d Then, the rotation is attenuated by the rotary damper 3e to weaken the rotation. As a result, the rotation and movement of the horizontal body 3 and the door body 2 suspended therefrom are slowed, and the door body 2 slowly approaches the vertical frame 1b to reduce noise and vibration caused by the contact. Vertical handles 6, 7, 8 are attached to the door surface material 2a of the door body 2, and push the handle 7 in the toilet room 9, pull the handle 8 in the corridor 10 side, or pull the handle 6 in the toilet room 9. By pulling, the grips 6, 7, 8 rotate around their bases, and the latch advance / retreat mechanism 5a operates to release the latch 5 and unlock the latch 5 of the door body 2.
