And an opening frame 14 for suspending and housing the door main body 1 so as to be freely openable and closable in the width direction, and a door pocket 26 forming one side end of the opening frame 14.

[0006] The door body 1 is formed by connecting a large number of slats 2 so as to be able to bend in the width direction, and is used for winding. In this example, the multiple slats 2 of the door body 1 are made of hard synthetic resin. The door main body 1 is made of a synthetic resin by using a flexible synthetic resin connecting member 5 and is made of a synthetic resin. A ventilation hole 8 communicating with each slat 2 as an upper part on the undressing room side and a lower part on the bathroom side.
The ventilation holes 8 are communicated so as to reach the lower ends of the slats 2 where the ventilation holes 8 are formed.

That is, in this embodiment, the slat 2 is made of an extruded material of hard vinyl chloride resin, has connecting grooves 3 on both sides in the width direction, and is slightly curved inward, that is, toward the bathroom. Closed-cell foam resin, such as urethane foam 4, which is constructed as a hollow bar material or has improved heat insulation in its hollow portion.
For example, a width of 5 cm or less for winding, and a width of 3 cm, particularly suitable for small diameter winding, and a width of 1.8 to 1.9 m or 2.0 m. , Which are connected in a relatively dense manner using, for example, a large number of 30 pieces or more to bend in the width direction toward the inside of the room, for example, having a width of 0.9 m to 1. The connecting member 5 is made of, for example, the same extruded material of a soft vinyl chloride resin, and has a bulging portion 6 for fitting on both sides in the width direction. And the fitting bulging portions 6 are fitted into the connecting grooves 3 adjacent to each other of the slats 2 juxtaposed in parallel in the width direction. The connecting member 5 is mounted between the slats 2 by means of The slats 2 are flexibly connected to the bathroom side by bending portions 7 to form the door main body 1.

At this time, the ventilation hole 8 uses the hollow portion of the hollow bar-shaped slat 2 or, when the foamed resin 4 is filled therein, forms the hollow portion below the slat 2 and the middle portion in the longitudinal direction thereof. The hollow portion is formed so as to extend partially or to the lower end so as to reach the lower end, and is provided as a communication passage for air so as to allow ventilation between the inside and outside of the door body 1. The ventilation hole 8 is located on the dressing room side of the outside of the door body 1 and has an external ventilation port 9 on the lower upper portion of the slat 2 which is about 30 cm from the floor surface, and is 10 cm from the floor surface on the bathroom side inside the door body 1. Internal ventilation openings 10 are formed below and below the slats 2 by arranging the ventilation openings 9 and 10 in steps of 10 to 15 cm between the inside and outside. From the internal ventilation opening 10 It remains hollow, including the part that reaches its lower end.

The door main body 1 is provided with an upper suspension door wheel 11 for opening and closing the opening frame 14 so as to be freely openable and closable in the width direction. Each of the upper ends of each slat 2 or a predetermined upper end of the slat 2 is rotatably supported so as to be perpendicular to the slats 2. In the example, the roller is rollably mounted on the upper suspension rail 16 provided in the horizontal shallow groove provided on the undressing room side to guide the traveling thereof, and the lower end of the door main body 1 is formed with the upward opening groove formed in the lower frame 17. The upper frame 15 is inserted into the rail 18 so as to be guided in a running manner, and is supported on the upper frame 15 by the upper suspension door 11 at the lower end under the vibration guide at the lower end.
The door body 1 can be freely opened and closed in the width direction.

The door pocket 26 is arranged so as to define one end of the opening frame 14 and receive and open the ends of the upper suspension rail 16 and the groove rail 18, and incorporates a winding device 27. The take-up device 27 incorporated in the door pocket 26 in this example is provided for taking up and storing the door body 1.
A winding shaft 29 which is fixed to an end of the door body 1 in the width direction and is arranged so as to be urged and rotated in the winding direction by a spring 30.
And a slat receiving disk 33 which is fixed to the lower end of the winding shaft 29 and receives and places the lower end edge of the door body 1 of the winding shaft 29 winding.

In other words, in this embodiment, the door pocket 26 is separated from the upper frame 15 and the lower frame 17 so that the upper frame 15 and the lower frame 17 and the one side end thereof are framed in place of the vertical frame on one side of the opening frame. For example, the upper suspension rail 16 and the groove rail 1 may be formed in a vertically long hollow box shape protruding toward the indoor side so that the door body 1 in the upper frame 15 and the lower frame 17 can be opened and closed.

The door frame 26 is smoothly wound and stored in the door pocket 26 while being supported and opened, and the opening frame 14 is largely opened except for the door pocket space corresponding to the winding diameter of the door main body 1, so that the opening can be set as a bathroom entrance. If the door opening side is pulled while the door opening side is pulled to make full use of the width of the part, the winding shaft 29 rotates in the opposite direction so as to apply the urging force of the spring 30 to the winding shaft 29. Then, each of the upper suspension door rollers 11 enters the upper suspension rail 16 similarly to the preceding upper suspension door roller 11 and the lower end similarly enters the groove rail 18, and the door main body 1 is smoothly sent out and closed, and the opening frame 14 is blocked. It can be closed, and at this time the door body 1 exhibits heat insulation. It is possible to ventilate the inside and outside through the ventilation holes 8. At this time, even if water such as splashes at the time of bathing falls on the door body 1, the water reaches the external ventilation port 9 higher than the internal ventilation port 10. Is prevented, and the dressing room is not soiled. In this example,
Since the ventilation hole 8 communicates with the lower end of the slat 2, water from the internal ventilation port 10 can be drained to the groove rail 18 of the lower frame 17.
