The mounting method will be described below with reference to FIGS. 11A to 13B.

<Installation of upper fixing member 20>
In order to attach the upper fixing member 20 to the headbox 2, first, as shown in FIGS. 11A and 11B, the rear side hook-shaped portion 21b of the upper fixing member 20 is attached to the flange portion 2a1 at the upper end of the rear wall 2a of the headbox 2. to engage. In this embodiment, the rear hook-shaped portion 21b constitutes the first claw portion in the claims. The flange portion 2a1 is formed along the longitudinal direction of the headbox 2. As shown in FIG. Next, the upper fixing member 20 is slid toward the end in the longitudinal direction of the head box 2, as shown in FIGS. Then, the upper fixing member 20 is locked and fixed to the head box 2 by causing the locking claws 22 a (see FIG. 5B) of the upper fixing member 20 to ride over the box cap 2 b at the end of the head box 2 . In this embodiment, the locking claw 22a constitutes the second claw portion in the claims.

<Mounting of Engagement Member 40>
The engaging member 40 is attached to the bottom rail 4 from below, as shown in FIGS. 6B-6A and 7B-7A. At this time, the front claw portion 41 a engages with the front edge of the bottom rail 4 , the rear claw portion 41 b engages with the rear edge of the bottom rail 4 , and the clamping portion 41 clamps the bottom rail 4 . 7A, the engaging member 40 is attached at a position where the holding portion 43 protrudes from the longitudinal end portion (end surface) 4a of the bottom rail 4. As shown in FIG.

In this embodiment, the holding portion 43 is configured to surround the guide cord 30 together with the longitudinal end portion (end surface) 4a of the bottom rail 4, as shown in FIGS. 6A and 7A. Further, as shown in FIG. 7B, the holding portion 43 has a gap 43a that opens toward the rear side (outdoor side) and does not surround the guide cord 30, and holds the guide cord 30 through the gap 43a. Positioning within the portion 43 is possible.

6C, the engaging member 40 of the present embodiment is configured to be accommodated on the longitudinal end side of the tape holder 4h that holds the warp threads 5a and 5b of the ladder cord 5. As shown in FIG. That is, it is provided separately from the tape holder 4h. Therefore, even if the engaging member 40 is attached after the tape holder 4h is attached, they do not interfere with each other.

<Installation of guide cord 30>
As shown in FIG. 4, the guide cord 30 has its upper end passed through the through hole 23 (see FIG. 5A) of the upper fixing member 20, and is supported by the arm portion 22 by forming a knot ball 31. As shown in FIG. The lower end side of the guide cord 30 is passed through the holding portion 43 of the engaging member 40 and attached to the lower fixing member 50 .

<Installation of lower fixing member 50>
The lower fixing member 50 is constructed by first fixing the base member 51 to the floor surface F and then sliding the holder member 52 in the direction of the arrow in FIGS. 9 and 10 to fit. At this time, as shown in FIGS. 13A and 13B, the guide cord 30 is passed through the insertion groove 52i, and the knot ball 32 formed at the end thereof is hooked on one of the plurality of fixed grooves 52f. The guide cord 30 is fixed to the floor surface F by keeping it. The position of the knot 32 is adjusted so that the guide cord 30 is stretched between the upper fixing member 20 and the lower fixing member 50 under tension. That is, in the present embodiment, the plurality of fixing grooves 52f constitute adjusting means in the claims.

The position of the guide cord 30 attached as described above with respect to the slat 3 is as shown in FIG. That is, in the left-right direction, the longitudinal outer ends of the slats 3 and the guide cords 30 are arranged adjacent to each other with a small distance therebetween. The reason why the guide cord 30 can be arranged in such a position is that the arm portion 22 of the upper fixing member 20 protrudes slightly from the box cap 2b of the head box 2, and the holding portion 43 of the bottom rail 4 is positioned as shown in FIGS. As shown in FIG. 7A, this is because the guide cord 30 is surrounded by the longitudinal end (end face) 4a of the bottom rail 4. As shown in FIG. In addition, in the front-rear direction, the guide cord 30 is arranged at a position slightly shifted rearward from the center of the slat 3 in the width direction.

Then, when the upper fixing member 20, the guide cord 30, the engaging member 40, and the lower fixing member 50 are attached as described above, the vibration suppressing device 10 can be mounted on the ceiling surface and the floor surface as shown in FIG. It is designed to fit inside the window frame, etc. Specifically, the upper fixing member 20 is installed between the head box 2 and the ceiling surface (including the upper surface of the window frame). Further, the guide cord 30 is fitted between the longitudinal ends of the head box 2, the slats 3 and the bottom rail 4 and the window frame. Therefore, it is also possible to additionally install the shaking suppressing device 10 to the horizontal blind already installed on the window frame or the like by using the gap between the horizontal blind and the window frame or the like.

1-4 Fail-safe By the way, when the above-described sway suppressing device 10 is attached to the horizontal blind, it is possible to suppress swaying of the slats 3 and the bottom rail 4 (hereinafter referred to as slats, etc.). By regulating the movement of the slats and the like, there is a risk that an overload will be applied. Specifically, for example, when a force P in the front-rear direction is applied to the slats and the like as shown in FIG. power can escape. However, with the vibration suppressing device 10, the holding portion 43 of the engaging member 40 is held by the guide cord 30, so the force cannot be released. Therefore, the head box 2 that holds the slats and the like is subject to a load and may fall.

Therefore, the horizontal blind 1 of the present embodiment is provided with a tension relief mechanism for relaxing the tension of the guide cords 30 when a predetermined tension is applied to the guide cords 30 as a fail-safe mechanism for the vibration suppressing device 10. ing. In this embodiment, the lower fixing member 50 constitutes a tension relief mechanism. Specifically, as shown in FIG. 14A, when a tension greater than or equal to a predetermined threshold (predetermined tension) is applied to the guide cord 30, as shown in FIG. It is configured to be disengaged from member 51 . At this time, the slide protrusion 52s of the holder member 52 gets over the upper edge of the slide groove 51s of the base member 51, so that the base member 51 and the holder member 52 are separated. As a result, the guide cord 30 that has been locked to the holder member 52 is released and its tension is relaxed. With such a configuration, the horizontal blind 1 of the present embodiment can protect the product even when overloaded by strong wind or the like.

1-5 Effect (1) In the horizontal blind 1 to which the shaking suppression device 10 is attached, the guide cord 30 is arranged on the outer side in the longitudinal direction of the multiple stages of the slats 3 and the bottom rails 4. It is possible to prevent the slat from swinging in the longitudinal direction (lateral direction) without impairing the
(2) Since the guide cord 30 is held by the holding portion 43 of the engaging member 40 attached to the bottom rail 4, it is possible to prevent the front-rear swaying.
(3) Since the guide cord 30 is suspended from the upper fixing member 20 detachable from the head box 2 and held by the retaining portion 43 of the engaging member 40 detachable from the bottom rail 4, the guide cord is retrofitted. It is possible to
(4) Since at least the upper fixing member 20, the guide cord 30, and the lower fixing member 50 can be used for both left and right sides, it is possible to reduce the number of parts and the cost.

The same swing suppressing device 10 used in the horizontal blind 1 can be used for different types of head boxes 2 having different lengths in the longitudinal direction. That is, the upper fixing member 20 of the vibration suppressing device 10 can be attached to a head box 92 shown in FIG. 15, which is shorter in the longitudinal direction than the head box 2 shown in FIG. In this case, first, as shown in FIGS. 16A and 16B, the front side hook-shaped portion 21a of the upper fixing member 20 is engaged with the collar portion 92c1 of the front wall 92c of the head box 92. Then, as shown in FIG. In the case of this form, the front side hook-shaped portion 21a constitutes the first claw portion in the claims. 12A and 12B, the upper fixing member 20 is then attached to the headbox 92 by sliding the upper fixing member 20 toward the longitudinal ends of the headbox 92 . However, in this case, the upper fixing member 20 also engages the upper end of the rear wall 92a and the upper end of the cap 92b. In this case, the guide cord 30 hangs down from the rear through-hole 23 of the two arms 22 of the upper fixing member 20 . 4, the length in the front-rear direction is shorter than the length in the front-rear direction of the slats 3, as shown in FIG. 11B. On the other hand, the head box 92 shown in FIG. 15 has a length in the front-rear direction substantially the same as the length in the front-rear direction of the slat 3, as shown in FIG. 16B.

Thus, the vibration suppressing device 10 of this embodiment can be retrofitted to a plurality of products.

In the above-described embodiment, as shown in FIG. 2, the slat 3 has a configuration in which the ladder cord 5 and the lifting cord 6 are engaged with the notch 3a to suppress the displacement in the longitudinal direction. However, as shown in FIG. 18A, it is also possible to provide a through hole 3b in the slat 3 and insert the lifting cord 6 through the through hole 3b. Moreover, as shown in FIG. 18B , the position where the through hole 3b is provided may be near the end of the slat 3 .

In the above embodiment, the upper fixing member 20 and the engaging member 40 are detachable from the head box 2 and the bottom rail 4, respectively. be.

2. Second Embodiment Next, a vibration suppression device 10 (vibration suppression kit) according to a second embodiment will be described with reference to FIGS. 19 to 20B. A vibration suppression device 10 of the second embodiment differs from that of the first embodiment only in the configuration of an upper fixing member 120 . Therefore, only the differences will be described below.

The upper fixing member 120 of the present embodiment is detachably attached to the head box 2 and suspends the guide cord 30, like the upper fixing member 20 of the first embodiment. The upper fixing member 120 is configured to be attached to the box cap 2b of the headbox 2, as shown in FIG. Specifically, as shown in FIGS. 20A and 20B, the upper fixing member 20 includes a side wall portion 121, a top wall portion 122 as a locking portion, a rear wall portion 123, and a guide cord support portion 124.
