As a result, the work for attaching and removing the cover 16 to the head box 11 via the attachment 17 can be performed without using a tool such as a screwdriver, so that the workability of attachment and removal can be improved. Further, without using the resin elasticity of the upper claws 24 and the lower claws 23, the upper claws 24 and the lower claws 23 urge the head box 11 by the elastic force of the compression coil springs 26 provided separately from these claws 24 and 23. Since it is held in a sandwiched state, even if it is used for a long time, the situation where the elastic force of the upper claw 24 and the lower claw 23 is not reduced does not occur. As a result, it is possible to prevent the cover 16 from being unintentionally detached from the head box 11. Further, since the lower claw 23 is provided integrally with the base 21, the operation code 14 for operating the blind 12 suspended from the head box 11 is operated while being pulled diagonally forward. Even if the cover 16 touches the cover 16 in the direction in which the cover 16 is pushed up, the lower claw 23 does not come off from the front lower rail 11g. As a result, it is possible to prevent the cover 16 from unintentionally falling off the head box 11.

<Second Embodiment>
6 to 10 show a second embodiment of the present invention. 6 to 10, the same reference numerals as those in FIGS. 1 to 5 denote the same components. In this embodiment, the cover 16 is attached not only to the front side of the head box 11 but also to the back side of the head box 11 via the fixture 17 (FIGS. 6 to 8 and 10). That is, in this embodiment, the blind device 40 is used not to cover the window of the room but to divide the room into a plurality of small rooms. For this reason, the curtains, roll screens, roman shades, panel screens, pleated screens, partitions or accordion doors may be used instead of the blinds 12. The bracket 19, the fixture 17 and the cover 16 of this embodiment are the same as the bracket, the fixture and the cover of the first embodiment, respectively. As a result, the number of parts does not increase and parts management becomes easy. The bracket 19 is attached to the ceiling 41.

  In the fixture 17 interposed between the back of the head box 11 and the cover 16, the sliding shaft 22 is inserted into the back upper hole 21h of the upper plate 21b of the base 21 and the back lower hole 21i of the lower plate 21c. (FIGS. 6 and 7). The center of the rear upper hole 21h is formed closer to the main plate 21a than the center of the front upper hole 21f by the offset amount of the rear lower rail 11i, and the center of the rear lower hole 21i is the front lower hole 21g. It is formed closer to the main plate 21a side by the offset amount of the back side lower rail 11i than the hole center. This is because the front-side lower rail 11g is positioned on the extension line of the front piece 11b, whereas the back-side lower rail 11i is uniformly (offset) toward the wall 18 by a predetermined distance from the back piece 11c. That is, the distance of the front-side upper rail 11f that extends in the front-rear direction from the front of the head box 11 is the same as the distance that extends in the front-rear direction from the back of the head box 11 of the rear-side upper rail 11h. When the attachment 17 is attached to the back surface of the head box 11, the distance that is uneven in the front-rear direction from the front of the box 11 is different from the distance that is uneven in the front-rear direction from the back of the head box 11 of the back side lower rail 11 i. Is formed on the front plate 21b and the upper plate 21b of the rear side upper hole 21h, and is formed on the lower plate 21c of the front side lower hole 21g and the rear side lower hole 21i. It is configured to have different positions.

  Further, in the fixture 17 interposed between the back surface of the head box 11 and the cover 16, the lower claw 23 is engaged with the rear lower rail 11i, and the upper claw 24 is engaged with the rear upper rail 11h. (FIG. 6). Further, the rear ring groove 22b of the sliding shaft 22 is formed at a position away from the upper claw 24 by a predetermined distance from the front ring groove 22a. The predetermined distance is the length obtained by subtracting the protruding length from the lower piece of the front side lower rail 11g from the protruding length from the lower piece of the rear side lower rail 11i. This relates to the spring pressure of the compression coil spring 26 when the lower claw 23 is locked to the front side lower rail 11g and the upper claw 24 is locked to the front side upper rail 11f, and the lower claw 23 to the back side lower rail 11i. This is to make the spring pressure of the compression coil spring 26 substantially the same when the upper pawl 24 is stopped and the upper pawl 24 is locked to the rear upper rail 11h. The configuration other than the above is the same as that of the first embodiment.

  A procedure for attaching the cover 16 to the head box 11 of the blind device 40 configured as described above will be described. First, the horizontal portion 19b of the bracket 19 is attached to the ceiling 41 of the room with a tapping screw (not shown). Next, with the upper piece of the first receiving portion 11d of the head box 11 being locked to the first claw 19c of the bracket 19, the central piece of the second receiving portion 11e of the head box 11 is moved to the second claw 19d of the bracket 19. To lock. As a result, the head box 11 is attached to the ceiling 41 via the bracket 19. On the other hand, after the sliding shaft 22 is inserted into the front upper hole 21f of the base 21, a compression coil spring 26 is loosely fitted to the inserted sliding shaft 22, and the sliding shaft 22 is further inserted into the front lower hole 21g. Insert. Then, a C-type retaining ring 27 is attached to the front ring groove 22 a of the sliding shaft 22. This completes the assembly of the front-side fixture 17. Next, after the tapping screw 28 is inserted into the through-hole of the flange 21j of the front-side fixture 17, the front-side fixture 17 is attached to the front-side cover 16 by screwing the tapping screw 28 into the cover 16.

  Next, a procedure for removing the cover 16 attached to the head box 11 will be described. While the front cover 16 is attached to the front of the head box 11 via the front attachment 17, the sliding shaft 22 is pushed up against the elastic force of the compression coil spring 26, and the lower claw 23 is mainly shown. The upper claw 24 is detached from the front upper rail 11f by rotating in the direction opposite to the broken line arrow 6 (a). Thereby, the front side cover 16 can be removed from the front side of the head box 11 together with the front side attachment 17. Next, with the back cover 16 attached to the back of the head box 11 via the back attachment 17, the lower claw 23 is centered while pushing the sliding shaft 22 against the elastic force of the compression coil spring 26. The upper claw 24 is detached from the rear side upper rail 11h by rotating in the direction opposite to the one-dot chain line arrow in FIG. Thereby, the back side cover 16 can be removed from the back side of the head box 11 together with the back side mounting tool 17. As a result, the work for attaching and removing the cover 16 to the head box 11 via the attachment 17 can be performed without using a tool such as a screwdriver, so that the workability of attachment and removal can be improved. Since operations other than those described above are substantially the same as those in the first embodiment, repeated description will be omitted.
