The part cannot be separated from the interval H between the one locking piece 21a and the other locking piece 21b. For this reason, it can prevent that the other end of the screen 16 remove | deviates from the seat groove 21 in a normal use condition.

  In the roll blind according to the present invention, the other end of the screen is accommodated inside the screen fixing member so that the length of the screen can be adjusted, so that when the length of the screen is insufficient or the length is too long. The length of the screen can be adjusted by accommodating the other end of the screen inside the screen fixing member or pulling out the other end of the screen from the inside of the screen fixing member. In particular, if the other end of the screen is wound around the mounting rod and accommodated in the seat groove together with the mounting rod, the total length of the screen can be increased by increasing or decreasing the number of times the screen is wound around the mounting rod. The thickness can be adjusted relatively easily. And the winding side of the screen in the cross section of the mounting rod can be inserted / removed with a gap in a state where the drawer side of the screen in the cross section of the mounting rod is accommodated in the other side of the seat groove. By doing so, it is possible to relatively easily fix and remove the seat from the seat groove at the other end of the screen.

In this case, one end is fixed to the bottom wall of the seat groove, and the other end is pulled out of the seat groove from the interval between one locking piece and the other locking piece. If it is provided, the other end of the screen can be easily detached from the seat groove by a relatively simple action of simply pulling and extending the other end of the release tape.
On the other hand, if the cover member is detachably attached to one locking piece, the sum of the distance between the cover member and the other locking piece and the width of the other locking piece is smaller than the major axis in the cross section of the mounting rod. As a result, it is possible to effectively prevent the other end of the screen from coming out of the seat groove in a normal use state.

Then, the drawer 16 side of the screen 16 in the cross section of the mounting rod 22 comes into contact with the other locking piece 21 b, and the mounting rod 22 is prevented from rotating inside the seat groove 21. One end of the screen 16 is fixed.

  In this embodiment, the cover member 26 that narrows the distance H between the one locking piece 21a and the other locking piece 21b is attached to the one locking piece 21a. This attachment is performed by inserting one locking piece 21a between the pair of sandwiching pieces 26a, 26b in the cover member 26. Then, even if the mounting rod 22 moves inside the seat groove 21 and moves so that its pull-out side portion is accommodated in the other side portion of the seat groove 21, as shown in FIG. Due to the presence of the member 26, the winding side portion of the mounting rod 22 is not separated from the interval H between the one locking piece 21a and the other locking piece 21b. For this reason, it can prevent that the other end of the screen 16 remove | deviates from the seat groove 21 in a normal use condition.

  On the other hand, after the roll blind 10 is installed, if the length of the screen 16 becomes insufficient or is too long, the length of the screen 16 is adjusted. This adjustment is performed after the other end of the screen 16 is removed from the support bar 11. Specifically, first, as shown in FIG. 2D, one locking piece 21a is detached from between the pair of sandwiching pieces 26a and 26b, and the cover member 26 is detached from the one locking piece 21a. . Thereafter, the pull-out side portion of the mounting rod 22 is accommodated in the other side portion of the seat groove 21, and in this state, the winding side portion of the mounting rod 22 is pulled out from the seat groove 21 via the interval H. In this embodiment, the release tape 24 having one end fixed to the bottom wall of the seat groove 21 and the other end pulled out of the seat groove 21 from the interval H is provided on the inner surface of one side of the seat groove 21. The release tape 24 is extended by pulling the other end of the release tape 24, and the winding side portion of the mounting rod 22 accommodated in one side portion of the seat groove 21 is separated by the interval H by the extended release tape 24. To leave. As a result, the mounting rod 22 around which the other end of the screen 16 is wound is removed from the seat groove 21. Therefore, when fixing the other end of the screen, it is not necessary to shift the mounting rod, which has been conventionally required, in the longitudinal direction of the support bar or the winding rod. Further, since the screen fixing member 18 can be swung, when the other end of the screen 16 is fixed to the seat groove 21 via the mounting rod 22 or when the mounting rod 22 is detached from the seat groove 21, The opening of the seat groove 21 formed in the screen fixing member 18 can be directed in the direction in which the operation is easy. For this reason, in this invention, fixation and removal of the other end of the screen 16 with respect to the seat groove 21 can be made easier than in the past.

  Next, the mounting rod 22 around which the other end of the screen 16 is wound is rotated, and the number of windings of the screen 16 around the mounting rod 22 is increased or decreased to adjust the total length of the screen 16. That is, in this embodiment, since the mounting rod 22 in the normal state shown in FIG. 3C in which the other end of the screen 16 is wound 1.5 times is accommodated in the seat groove 21, When the length becomes insufficient, as shown in FIG. 3B, the number of windings of the screen 16 around the mounting rod 22 is decreased, and the screen 16 is not wound around the mounting rod 22. Increase the total length. On the other hand, when the length of the screen 16 is too long, the number of windings of the screen 16 around the mounting rod 22 is increased as shown in FIG. The total length of the screen 16 in the part is reduced. After adjusting the total length of the screen 16 in this way, the mounting rod 22 is again accommodated in the seat groove 21 by the same procedure as described above, and the length of the screen 16 is adjusted relatively easily.

In the above-described embodiment, the mounting rod 22 having a rectangular cross section has been described as a representative. However, the mounting rod 22 may be a rod-shaped member having an oval or elliptical cross section. good.
In the embodiment described above, the case where the other end of the screen 16 is fixed to the seat groove 21 formed in the support bar 11 of the roll blind 10 via the mounting rod 22 has been described. You may apply when fixing the end of the screen 16 to the seat groove 13a formed in the rod 13. FIG.
Furthermore, although the case where the support bar 11 is attached to the ceiling 10b has been described in the above-described embodiment, the support bar 11 may be attached to a wall surface as shown in FIG.
