The sealing member 6 is a drainage member extending in the vertical direction over the entire length of the two guide rails 1. As shown in FIGS. 2 and 3, the movable frame 7 is integrally attached to the distal end. This movable frame 7
Is a bent piece 7a formed at the end opposite to the sealing member 6, and a seal projecting to the opposite side to the bent piece 7a.
An engaging pin 8 as a member-side engaging member is integrally provided.

Reference numeral 9 denotes a bracket for guiding a sealing member integrally provided on the inner wall portions of the guide rails 1. The bracket 9 is provided with a pin guide groove (engaging groove) 10. This pin guide groove 10 is shown in FIGS.
As shown in FIG. 5, the lower end is a groove that is inclined in a direction to gradually approach the panel 4.

The sealing member 6 is inserted into the pin guide groove 10.
When the engagement pin 8 of the system is slidably fitted and engaged, and the engagement pin 8 is held above the pin guide groove 10, the sealing member 6 is separated from the panels 4 and 4A, Further, as the engagement pin 8 moves to the lower end side of the pin guide groove 10, the sealing member 6 moves in a direction in which the sealing member 6 comes into close contact with the panels 4 and 4A. Therefore, the sealing member 6 can be moved between a sealing position where the sealing member 6 is in close contact with the panels 4 and 4A and a sealing releasing position where the sealing member 6 is separated from the panels 4 and 4A.

Reference numeral 13 denotes an engagement pin as a panel-side engagement member protruding from one side of the vertical frame on both sides of the panel 4 at an arbitrary position in the series of panels 4 and 4A. When the panels 4 and 4A are moved up and down, they are engaged with and disengaged from the engagement pins 8 of the six sealing members above the engagement pins 8.

Reference numeral 14 denotes a bottom leaf spring as a bottom elastic member provided on each of the inner bottoms of the guide rails 1. The bottom leaf spring 14 bulges opposite both lower end surfaces of the lowermost panel 4A. It has a bent bottom piece 14a, an intermediate bent point 14b that rises from one end of the raised bent bottom piece 14a and abuts against the inner wall surface of both guide rails 1, and the tip is the lower end of the sealing member 6. It is integrally formed in the illustrated example shape comprising the rising bent piece 14c engaged with the back surface by pressure contact. The bottom leaf spring 14 is configured to swell the bent bottom piece 1.
4a is pushed and stretched on the lower end surface of the lowermost panel 4A, so that the lower end of the sealing member 6 is pressed and displaced by the rising bent piece 14c in a sealing direction in which the lower end of the sealing member 6 is brought into close contact with the lowermost panel 4A. .

Next, the operation will be described. 6 to 8 are explanatory diagrams of the operation. In a state where all the panels 4 and 4A are stored and suspended in a parallel fold in the panel storage section 2,
When the panels 4 and 4A are fed out between the two guide rails 1 and the lowermost panel 4A reaches the vicinity of the ground, the engaging pins 13 on the panel 4 are moved upward by the engaging pins 8 of the six sealing members. And the engaging pin 8 is pushed down.

At this time, the engaging pin 8 is obliquely guided toward the panel 4 by the pin guide groove 10, so that the sealing member 6 integrated with the movable frame 7 resists the urging force of the leaf spring 12. When the engagement pins 8 move down to the lower end of the pin guide groove 10 or in the vicinity thereof at the time when the engagement pins 8 are moved down to the side of the panels 4 and 4A, a state where the two guide rails 1 are fitted in the up and down direction with no gap therebetween. The sealing member 6 comes into close contact with one side surface of the vertical frame on both sides of the series of panels 4 and 4A. Therefore, in the shutter fully closed state, the gap between both guide rails 1 and each of the panels 4 and 4A is sealed by the sealing member 6, thereby preventing rainwater from entering the room from the outside.

In addition, during the shutter fully closing operation as described above, immediately before the lowermost panel 4A touches the ground, the raised bent bottom piece 14a of the bottom leaf spring 14 is pushed out at the lower end surface of the lowermost panel 4A. Thereby, the lower end side of the sealing member 6 is moved to the lowermost panel 4A by the rising bent piece 14c.
Is pressed into close contact. Therefore, the sealing performance of the panels 4 and 4A by the sealing member 6 is further improved.

When each of the panels 4 and 4A starts ascending operation from such a fully closed state of the shutter, the engaging pin 13 on the panel 4 moves upward in a direction away from the engaging pin 8 on the sealing member 6 side. When the engagement pins 13 and 8 are disengaged from each other, the sealing member 6 is moved away from the panels 4 and 4A by the urging force of the leaf spring 12, and the sealing is released.

At substantially the same time, the lowermost panel 4A rises and separates from above the bottom leaf spring 14, and the bottom leaf spring 14 is elastically restored, so that the lower end side of the sealing member 6 is also attached to the leaf spring 12. The force separates from the lowermost panel 4A. Therefore, the panels 4 and 4A smoothly move up in the storage direction along the guide rail 1 without receiving the frictional resistance of the sealing member 6.

In the above-described embodiment, the leaf spring 12 may be another elastic member such as a coil spring or rubber or elastic resin material. In this case, the same operation and effect can be obtained. Further, between the movable frame 7 and the bracket 9 and / or between the bent end portion of the spring receiving piece portion 11 and the movable frame 7, a water-tight sealing member allowing the movement of the movable frame 7. May be provided.
