(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In the horizontal blind shown in FIG. 1, a multi-stage slat 2 is supported on a ladder tape 1 supported by suspension from a head box (not shown), and a bottom rail 3 is attached to the lower end of the ladder tape 1. The slat 2 is formed of a wooden flat plate, and the bottom rail 3 is formed of a solid wood having a rectangular cross section.

  The bottom rail 3 is attached to the lower ends of a pair of vertical tapes 4 of the ladder tape 1 via a lower limit position adjusting device. A specific configuration of the lower limit position adjusting device will be described with reference to FIGS.

  A hook-and-loop fastener 5a is attached to the inner surface of the lower end portion of the vertical tape 4 of the ladder tape 1, and a hook-and-loop fastener 5b that can be bonded to the hook-and-loop fastener 5a is attached to the bottom surface of the bottom rail 3. . A loop surface is formed on the surface of the surface fastener 5a, and a hook surface that engages with the loop surface is formed on the surface of the surface fastener 5b.

  Then, as shown in FIG. 2, with the bottom rail 3 positioned between the lower end portions of the vertical tape 4, the lower end portion of the vertical tape 4 is lifted toward the lower surface of the bottom rail 3, and the hook-and-loop fastener 5a is removed. Adhere to 5b. Then, a loop-shaped holding portion is formed at the lower end portion of the vertical tape 4, and the bottom rail 3 is held on the holding portion.

  Next, as shown in FIGS. 5 and 6, a plate-like bottom holder 6 is attached to the lower surface of the bottom rail 3 with screws 7 so as to cover the adhesive portions of the hook-and-loop fasteners 5 a and 5 b. Then, the lower end portion of the vertical tape 4 is sandwiched between the bottom holder 6 and the lower surface of the bottom rail 3, and the bottom rail 3 is securely held on the lower end portion of the vertical tape 4. When the slat angle adjusting device is operated in this state, each slat 2 and the bottom rail 3 are rotated in the same phase via the ladder tape 1.

  In the lower limit position adjusting device as described above, the lower limit position of the bottom rail 3 can be adjusted by adjusting the bonding position between the surface fastener 5a at the lower end of the vertical tape 4 and the surface fastener 5b on the lower surface of the bottom rail 3. is there.

  That is, when the position where the surface fastener 5a is bonded to the surface fastener 5b is the end side in the width direction of the bottom rail 3, the lower limit position of the bottom rail 3 is lowered. Moreover, if the bonding position of the hook-and-loop fastener 5a with respect to the hook-and-loop fastener 5b is the central portion side of the bottom rail 3, the lower limit position of the bottom rail 3 is raised.

With the horizontal blind bottom rail lower limit position adjusting apparatus configured as described above, the following operational effects can be obtained.
(1) The bottom rail 3 can be held at the lower end of the ladder tape 1 by bonding the surface fastener 5 a provided on the vertical tape 4 of the ladder tape 1 and the surface fastener 5 b provided on the bottom rail 3.
(2) The lower limit position of the bottom rail 3 can be easily adjusted by adjusting the bonding position of the hook-and-loop fasteners 5a and 5b.
(3) In order to increase the lower limit position of the bottom rail 3, if the lower end of the vertical tape 4 overlaps the lower surface of the bottom rail 3, cut the lower end of the vertical tape 4 as necessary. The hook-and-loop fastener 5a may be bonded to the hook-and-loop fastener 5b of the bottom rail 3.
(4) By removing the bottom holder 6 and adjusting the bonding position of the hook-and-loop fasteners 5a and 5b, the lower limit position of the bottom rail 3 can be easily adjusted even at the installation site.
(5) By attaching the bottom holder 6, the lower end portion of the vertical tape 4 can be securely held on the bottom rail 3.
(6) Since it is not necessary to provide a recess for accommodating the lower limit position adjusting device in the solid bottom rail 3, the rigidity of the bottom rail 3 is not lowered.
(7) Since the bottom end of the vertical tape 4 held on the lower surface of the bottom rail 3 by the hook-and-loop fasteners 5a and 5b can be covered with the bottom holder 6, the lower surface of the bottom rail 3 is rotated in the direction exposed to the indoor side. Even if it is done, aesthetics are not spoiled.
(Second embodiment)
7 to 9 show a second embodiment. In this embodiment, a hook-and-loop fastener is not attached to the lower surface of the bottom rail, and the lower end portion of the vertical tape of the ladder tape is bonded with the hook-and-loop fastener. The same components as those in the first embodiment will be described with the same reference numerals.

  As shown in FIG. 7, the vertical tape 4a hanging down to the indoor side is formed longer than the vertical tape 4b hanging down to the outdoor side, and a hook-and-loop fastener 8a is attached to the side of the indoor side at the lower end of the vertical tape 4a. Has been. Further, a hook-and-loop fastener 8b is attached to the lower end of the vertical tape 4b on the side surface facing the bottom rail 3.

  And as shown in FIG. 8, the lower end part of the vertical tape 4a is wound around the lower surface of the bottom rail 3, and the surface fastener 8a is adhere | attached on the surface fastener 8b of the vertical tape 4b. Then, the bottom rail 3 is hold | maintained at the lower end part of the longitudinal tapes 4a and 4b joined by the loop shape.

  Next, as shown in FIG. 9, a plate-like bottom holder 9 is attached to the lower surface of the bottom rail 3 with screws 7 so as to cover the vertical tape 4 a wound around the bottom rail 3. Then, the lower end portion of the vertical tape 4a is sandwiched between the bottom holder 9 and the lower surface of the bottom rail 3, and the bottom rail 3 is securely held on the lower end portion of the vertical tape 4a.

With the horizontal blind bottom rail lower limit position adjusting apparatus configured as described above, the following operational effects can be obtained.
(1) The bottom rail 3 can be held at the lower end portion of the ladder tape 1 by bonding the surface fasteners 8 a and 8 b attached to the vertical tapes 4 a and 4 b of the ladder tape 1.
(2) The lower limit position of the bottom rail 3 can be easily adjusted by adjusting the bonding position of the hook-and-loop fasteners 8a and 8b.
(3) By attaching the bottom holder 9, the lower end portion of the vertical tape 4 a can be reliably held on the bottom rail 3.
(4) Since it is not necessary to provide a recess for accommodating the lower limit position adjusting device in the solid bottom rail 3, the rigidity of the bottom rail 3 is not reduced.
(5) By adjusting the bonding position of the hook-and-loop fasteners 8a and 8b by loosening the bottom holder 9 from the bottom rail 3 to the extent possible with a gap between the bottom rail 3 and the bottom rail 3, the lower limit position of the bottom rail 3 is adjusted. Can be adjusted. Therefore, the lower limit position of the bottom rail 3 can be easily adjusted even at the installation site.
