Next, the opening and closing operation of the folding door 1 will be described.
First, as shown in FIG. 3, an operation of opening the door 1 from the closed state will be described.
When opening from the undressing room side, push the vertical center bar 25 of the door end side shoji 19 or the door front side shoji 17 to the bathroom side and slide the door holder 23 of the door front side shoji 17 from the door front side vertical frame 13b. Then, the door front side shoji 17 is moved to the rear side of the door. Thereby, when the central hook 21 protrudes to the bathroom side and the folding door 1 is opened until it is in the state shown in FIG. 1, the shoji stopper 45 attached to the longitudinal center 25 of the door tip side shoji 17 After coming into contact with and collapsing on the longitudinal middle rod 25, it elastically returns and a predetermined folding angle θ is held.
In the case of opening from the bathroom side, the handle 21a of the central hook 21 shown in FIG. 3 is pulled toward the bathroom side and continued to be pulled as it is or the central hook 21 is pulled a little and then the door tip side shoji 17 is pushed to the door butt side. Then, when the folding door 1 is opened until the state shown in FIG. 1 is reached and the folding angle θ between the door tip side shoji 17 and the door edge side shoji 19 becomes a predetermined angle, After the attached shoji stopper 45 abuts against the longitudinal middle ridge 25 of the door-side side shoji 19 and is crushed, it elastically returns, and a predetermined folding angle θ is maintained.

Furthermore, when it is desired to make the effective opening dimension larger in order to facilitate entry and exit than the state shown in FIG. 1, the door tip side shoji 17 is pushed toward the door edge side shoji 19 side in the operation from the bathroom side. . Then, as shown in FIG. 2, the shoji stopper 45 elastically deforms and collapses, and the door tip side shoji 17 moves to the door edge side shoji 19 side so that the folding angle θ becomes smaller. Thereby, the effective opening size of the folding door can be increased.
When it is desired to increase the effective opening size so as to facilitate entry and exit from the undressing room side, the door front side shoji 17 is pushed toward the door rear side shoji 19 side.
Thus, when the effective opening size is increased, the door on the butt end side 19 swings around the hanging rod 24 and the to butt end longitudinal center 25 approaches one bathroom wall surface 7 a, and The wall stopper 47 provided on the vertical middle bar 25 abuts on one bathroom wall 7a.
On the other hand, when the hand pressing the door tip side shoji 17 or the door contact 23 is released, the shoji stopper 45 in the collapsed state elastically returns, and the door contact side 23 of the door tip side sliding door 17 is the door front side It slides to the frame 13b side, and the folding door 1 returns to the state of the folding angle θ shown in FIG. At the same time, the wall stopper 47 separates from one bathroom wall 7a.

Next, as shown in FIG. 1, an operation of closing the door 1 from the opened state will be described.
When closing from the bathroom side, as indicated by the symbol F, the handle 21a of the central hook 21 is pushed toward the undressing room. As a result, the component force f acts on the door tip side shoji 17 and the door edge side shoji 19 inclined toward the bathroom side, and the horizontal force component f is applied to the door contact 23 of the door tip side shoji 17. The component fx acts, and the door 23 slides toward the vertical frame 13b. On the other hand, the horizontal component-fx acts on the lifting rod 24 for the component force f acting on the door edge side shoji 19, but since the lifting rod 24 does not move because it is a pivot shaft, it becomes a reaction force The horizontal component fx acts on the door contact 23. Therefore, the door holder 23 slides toward the vertical frame 13b with a predetermined force.
Thus, the sliding door 1 in the open state shown in FIG. 1 is in the closed state as shown in FIG. 3 by the sliding door 23 sliding toward the vertical frame 13b.
On the other hand, when closing the folding door 1 from the undressing room side, in the open state of the shoji shown in FIG. Push the handstand 23 on the handstand 23 to push or pull the handstand 23 to the side vertical frame 13b side, and when the closing is completed, the pull 46 on the longitudinal middle board 25 of the door front side shoji 17 or the door edge side shoji 19 Close to the dressing room side.

Next, the operation and effect of the folding door 1 according to the present embodiment will be described.
As shown in FIG. 1, when the folding door 1 is opened, the shoji stopper 45 provided on the longitudinal middle ridge 25 of the door front side shoji (one shoji) 17 is the longitudinal middle ridge of the back edge side shoji (the other shoji) 19 The door tip side shoji 17 and the door butt side shoji 19 are in a state of forming the folding angle θ by abutting on 25, so when closing from the bathroom side, by pressing the longitudinal center pin 25 through the center pin 21, A force acting in the direction to widen the folding angle θ acts on the folding door 1 so that the folding door 1 can be easily closed.
Moreover, when closing from the undressing room side, the fold door 1 can be easily closed by operating the door abutment 23 from the space S between the door abutment 23 and the hanging lever 24.

As shown in FIG. 2, since the shoji stopper 45 can be crushed by elastic deformation, it is possible to easily move in and out by collapsing the shoji stopper 45 and enlarging the effective opening size of the door. Further, since the folded door 1 is returned to the predetermined folding angle θ as shown in FIG. 1 by resiliently returning the crushed shoji stopper 45, the opened / closed operability is good because the folded door 1 is not closed more than necessary.
Since the shoji stopper 45 is detachable at an arbitrary position of the vertical middle rod 25, the door 1 is disposed by being disposed near the connecting portion (central ridge 21) between the door tip side shoji 17 and the door edge side shoji 19. The folding angle θ can be reduced by increasing the folding angle θ at the time of opening or placing the folding door 1 at a position away from the connecting portion (central bar 21). It can be selected.

As shown in FIG. 3, the longitudinal center ridge 25 having the bathroom side ridge 49 projecting toward the front tip side shoji 17 on the bathroom side in the closed state on the rear edge side shoji 19 and the longitudinal center ridge 25 Since the configuration is provided with the wall surface stopper 47 that holds and engages and fixes the bathroom side ridge 49, as shown in FIG. 2, the wall surface stopper 47 contacts one of the bathroom wall surfaces 7a when the folding door 1 is opened. By contacting, the door 1 can be prevented from colliding with one bathroom wall surface 7a.
The wall stopper 47 has a shape projecting at a predetermined length T (see FIG. 3) from the bathroom side looking surface of the door edge side shoji 19, so when opening the folding door 1 from the bathroom side, damaging one bathroom wall surface 7a Since the gap between one bathroom wall surface 7a and the folding door 1 can be secured and finger pinching can be prevented.

As shown in FIG. 9, since the wall stopper 47 is prevented from coming off by the vertical middle cap upper cap 41 at the upper end of the vertical middle rod 25, the wall stopper 47 can be fixed without using a fixing part such as a screw. Can be reduced and the assemblability is good.
Since the wall stoppers 47 are respectively provided on the longitudinal center 25 of the door front side shoji 17 and the longitudinal middle base 25 of the door rear side shoji 19, even when the folding door 1 is on the right side or on the left side, You can make it work even if you
