The upper runner fixed rail 5 is attached to the upper frame 4 at the fixed end of the folding door 2 as shown in the figure.
The upper frame 6 is attached over the entire length of the remaining upper frame 4,
The movement of the upper runner 3 of one panel 1 is stopped within the upper runner fixing rail 5, and the rollers 45 of the upper runner 3 of the other panel 1 are rolled on the upper surface of the horizontal piece 70 of the upper rail 6 to complete the folding door 2. The left and right hand of the folding door 2 can be changed by changing the left and right position of the upper runner fixing rail 5. Here, the upper runner fixing rail 5 is short and is attached to the upper frame 4 by being inserted from the side in the same manner as the upper rail 6, and one end is attached to the upper rail 6. A stopper 7 is continuous, the other end is in contact with the inner surface of the vertical frame 8, and the stopper 7 projects into the upper runner fixing rail 5 through a stopper mounting hole 72 provided approximately at the center in the longitudinal direction.
is attached to the stopper 7, and this stopper 7 is always urged upward by a coil spring 73 wrapped around its outer periphery, so that it can be pulled downward as necessary. Also, a part of the horizontal piece 74 of the upper runner fixing rail 5 between the stopper 7 and the vertical frame 8 is cut out to form an upper runner insertion opening 9, and from this upper runner insertion opening 9 the upper runner fixing rail can be inserted. The upper runner 3 inserted into the panel 5 is fixed between the stopper 7 and the vertical frame 8, and one end of the panel having the upper runner 3 is used as a fixed end, and the other end of the panel 1 is used as a movable end to create a folding door. 2, and when removing the upper runners 3, 3 of both panels 1, 1 from the upper frame 4, first pull out the upper runner 3 located on the upper runner fixing rail 5 from the upper runner insertion opening 9. Then, by folding the folding door 2, move the other upper runner 3 from the upper rail 6 to the upper runner fixing rail 5, pull down the stopper 7, and move the upper runner 3 past the stopper 7 into the upper runner insertion slot. 9 and take it out from the upper frame 6. On the other hand, the lower runner 53 protruding from the lower surface of each panel 1 is fitted with iron so that it can run freely into a rail groove 76 provided over the entire length of the lower frame 60, with one side serving as a fixed shaft.
The lower runner 53, which serves as a fixed axis, has a spacer 78 fixed to the end of the seal groove 76 with a screw 77.
The folding door 2 is caught between the vertical frame 8 and the vertical frame 8, and uses this as a rotation axis, while the other freely travels within the rail groove 76 to open and close the folding door 2. 8 in the figure is a decorative bar placed on both the upper and lower edges of each panel 1 and the outer edge of the outer vertical right 12, and an upper frame is placed on the side of the decorative bar 80 on the opposite side of the direction in which the panel pops out with the opening/closing operation. 6, a soft cushioning material 81 provided over the entire length of the lower frame 60 and the vertical frame 8 cushions the collision between each panel 1 and both the upper and lower frames 4, 60 when the folding door 2 is opened. In this way, the folding door 2 is extended in a straight line.
A latch 84 for holding the folding door 2 in the closed state protrudes from the upper end of the movable panel. A rod 901, which is housed in a fixed housing 88 so as to be movable up and down and is urged upward by a coil spring 89, protrudes upward, and when the folding door 2 is closed, the latch 84 resists the spring force. It protrudes beyond the horizontal piece 70 of the top rule 6 into the lower opening of the top rule 6 to hold the panel 1 in a closed state. still,
The folding door 2 shown in this embodiment is used as a bathroom partition, and a drain hole 92 is provided in the side wall of the rail register 76 in the longitudinal center of the lower frame 60, but the present invention does not necessarily include this. The present invention is not limited to the present invention, but can be applied to various other partitions. As described above, the present invention includes inserting the upper runner fixing rail into one side end of the upper frame disposed above the folding door, and inserting the upper runner fixing rail along the entire length of the remaining upper frame. Insert a top rail that fits the lotus, hang the top runner of one panel 1 from the top rail so that it can run freely, and attach it to the top runner fixing rail provided slightly inward from the side end of the top runner fixing rail. The upper runner of the other panel is positioned within the upper runner fixing rail between the stopper that protrudes and can be freely pulled down and the vertical frame that blocks the side ends of the upper runner fixing rail, and the stopper and the vertical frame are The upper runner fixing rail between the doors is equipped with an upper runner insertion opening that connects to the bottom, allowing the upper runner to be inserted and removed freely, so you can change the left-right hand of the folding door by simply reversing the left-right position of the upper runner fixing rail. Of course, by pulling down the stopper, the upper runner running on the upper rail can be moved beyond the stopper to the upper runner fixing rail, and each upper runner can be taken out from the upper runner insertion port, An advantage is that the folding door can be easily installed and removed.

That is, in the present invention, an upper runner having a rotatable roller at the tip protrudes from the upper surface of the outer end of each panel located at both ends of a folding door formed by hingedly connecting a plurality of panels. The top runner of one panel is suspended from the top rail so that it can travel freely, and the top runner of the other panel is positioned within the top runner fixing rail, so the folding door is suspended from the top rail by the top runner. It is suspended so that it can run freely, and runs smoothly when opening and closing.In this hanging type of folding door, the door protrudes slightly inward from the side edge of the upper runner fixing rail into the upper runner fixing rail. An upper runner insertion port is provided with a stopper that projects in the upper runner fixing rail so that it can move forward and backward in the upper runner fixing rail, and that opens downward so that the upper runner can be inserted into and taken out from the upper runner fixing rail between the stopper and the vertical frame. Since the upper runner is inserted into the upper rail from the upper runner insertion opening, the stopper provided in the upper runner fixing rail allows the upper runner to be inserted from the upper rail of one of the running upper runners. This prevents the upper runner from falling off and prevents the other fixed upper runner from running, and has the advantage that it can be easily attached to and removed from the upper runner of a hanging type folding door. be.
