Definitions

  • the present invention relates to a blind that can adjust the angles of a plurality of slats at different speeds.
  • a longitudinal blind has a hanger rail, a plurality of runners that are movable along the hanger rail, and a plurality of slats each of which is hung down from and supported by each runner.
  • the slats are deployed and folded up along the hanger rail, and the angle of each slat is adjusted to adjust the amount of light that enters a room through the longitudinal blind.
  • the material of the slats has a light blocking property.
  • a user rotates an operation rod (operation mechanism) or pulls an operation cord to adjust the angles of the slats at the same phase. Therefore, inside of the room is fully visible to the outside depending on the angles of the slats. Even if the light blocking slats and the semitransparent slats made, for example, of lace are alternately hung down from and supported, the slats cannot be adjusted such that only the semitransparent slats are deployed along the hanger rail seen from above. Therefore, even if slats made of different materials are hung down from and supported by the hanger rail, it is difficult to obtain conspicuous effects.
  • a longitudinal blind disclosed in Patent Document 1 supports a plurality of non-transparent louvers and a plurality of semitransparent louvers.
  • the non-transparent louvers and the semitransparent louvers are arranged alternately one by one.

  • the angle of the non-transparent louvers can be adjusted to adjust the non-transparent louvers so as to extend vertically with respect to the hanger rail as viewed from above.
  • the angle of the semitransparent louvers and the angle of the non-transparent louvers cannot be adjusted simultaneously by a single manipulation of the operation mechanism. That is, the above document discloses one embodiment in which only the angle of the non-transparent louvers can be adjusted and another embodiment in which each of the angle of the non-transparent louvers and the angle of the semitransparent louvers is adjusted independently.
  • Patent Document 1 Japanese Patent No. 3281544 EP0824179 discloses a vertical blind that includes a plurality of louvers of which certain louvers are alternately positioned and can be placed in various positions so that the vertical blind can be fully changed in form.

  • the support mechanisms include a first support mechanism that supports the first slat and a second support mechanism that supports the second slat.
  • the first support mechanism and the second support mechanism each have a drive force transmission mechanism.
