JP4856929B2 - Horizontal blind slat angle adjustment device - Google Patents

Description

  The present invention relates to a slat angle adjusting device for a horizontal blind in which the angle of an upper slat and a lower slat can be independently adjusted.

  As one type of horizontal blind, among the multiple slats supported suspended from the head box via a ladder cord, the angle of the upper slat and the lower slat can be adjusted independently. .

  In such horizontal blinds, the upper slats and the lower slats are suspended and supported by independent ladder cords, and the upper and lower slats are independently operated by operating each ladder cord separately. The angle can be adjusted.

Further, in order to prevent an unnecessary operation of the upper slat due to the operation of the ladder cord that supports the lower slat, the weft is cut off at the upper part of the ladder cord.
ACT 6-28137

  In the horizontal blind as described above, the upper weft thread of the ladder cord that supports the lower slats is cut, so that when all the slats are pulled up to the vicinity of the head box, the upper part of the ladder thread warp that supports the lower slats is It hangs down from both sides of the slat, which is not desirable from an aesthetic point of view.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the horizontal blind shown in FIG. 1, head boxes 1a and 1b are arranged side by side in a vertical direction, and a plurality of upper slats 2a are suspended and supported from the head box 1a, and a plurality of lower slats from the head box 1b. 2b is suspended and supported.

  More specifically, a drive shaft 3a is rotatably supported in the head box 1a and is driven to rotate by a motor 4a. A plurality of pulleys 5a are fitted on the drive shaft 3a, and a tilt tape 6a is hung on each pulley 5a. The first ladder cord 7a is suspended from each tilt tape 6a, and the slat 2a is supported by the first ladder cord 7a.

  An intermediate bottom bar 8 is suspended and supported at the lower end of the first ladder cord 7a. The slats 2a are rotated in the same phase based on the rotation of the drive shaft 3a. Further, after each slat 2a is rotated to a substantially vertical direction, the pulley 5a is idled with respect to the tilt tape 6a so that the slat 2a is not further rotated in the same direction.

  A drive shaft 3b is rotatably supported in the head box 1b and is driven to rotate by a motor 4b. A plurality of pulleys 5b are fitted to the drive shaft 3b, and tilt tapes 6b are respectively hooked on the pulleys 5b. The second ladder cord 7b is suspended and supported from the tilt tape 6b, and the slat 2b is supported by the second ladder cord 7b. The pulley 5a and the pulley 5b are provided at positions separated in the longitudinal direction of the head boxes 1a and 1b, and the tilt tape 6a and the tilt tape 6b do not interfere with each other. The first and second ladder cords 7a and 7b supported suspended from the respective tilt tapes 6a and 6b are suspended and supported at a predetermined interval so that the holding member 11a does not interfere with the ladder cord 7a. It has become.

  A bottom bar 9 is suspended and supported at the lower end of the second ladder cord 7b. Then, each slat 2b is rotated in the same phase based on the rotation of the drive shaft 3b. Further, after each slat 2b is rotated to a substantially vertical direction, the pulley 5b is idled with respect to the tilt tape 6b so that the slat 2b is not further rotated in the same direction.

  The upper and lower ends of the lifting tape 10 are wound around the pulleys 5b. Each lifting tape 10 passes through the slat 2a, the intermediate bottom bar 8 and the slat 2b, and the bottom bar 9 is suspended and supported at the lower end thereof.

  When the pulley 5b is rotated in the winding direction of the elevating tape 10 based on the rotation of the drive shaft 3b, the bottom bar 9 is pulled up and the slats 2b, 2a are sequentially lifted by the bottom bar 9. Further, when the pulley 5b is rotated in the rewinding direction of the elevating tape 10, the bottom bar 9 is lowered, and the slats 2a and 2b are sequentially returned to the state supported by the ladder cords 7a and 7b. Accordingly, the pulley 5b, the lifting tape 10 and the bottom bar 9 become a slat lifting device.

  A holding material 11a is inserted into the warp yarn above the second ladder cord 7b located on the side of the slat 2a at predetermined intervals and held by the slat 2a. As shown in FIG. 2, the holding member 11a is formed in an annular shape so as to surround the warp yarn of the ladder cord 7b by joining both ends of a string such as polyester. In this embodiment, the holding material 11a is disposed between every two slats 2a.

  Next, the operation of the horizontal blind constructed as described above will be described. When the drive shaft 3a is rotated by the operation of the motor 4a, the angle of the upper slat 2a is adjusted via the first ladder cord 7a.

  When the drive shaft 3b is rotated by the operation of the motor 4b, the angle of the lower slat 2b is adjusted via the second ladder cord 7b. When the drive shaft 3b is rotated in the winding direction of the elevating tape 10, the bottom bar 9 is pulled up, and the slats 2b, 2a are sequentially pulled up from the lower stage. When the drive shaft 3b is rotated in the rewinding direction of the elevating tape 10, the bottom bar 9 is lowered and the slats 2a and 2b are returned to the state supported by the first and second ladder cords 7a and 7b.

  A holding material 11a is attached to the warp yarn above the second ladder cord 7b at predetermined intervals. Then, when the bottom bar 9 is pulled up to the vicinity of the head box 1b and the slats 2a and 2b are stacked, the warp yarns on the upper part of the second ladder cord 7b are held between the slats 2a at predetermined intervals by the holding material 11a. .

Accordingly, when the slats 2a and 2b are folded up to the vicinity of the head box 1b, the warp yarn of the second ladder cord 7b can be prevented from hanging down. Moreover, since the 1st ladder cord 7a is not penetrated by the holding material 11a, interference with the 1st ladder cord 7a can be prevented.
