[0076] The first embodiment has the following advantages.

[0077] (1) When the light-shielding blades 2a and the translucent blades 2b are rotated about 180 degrees from the first fully closed state to be in the second fully closed state, the light-shielding blades 2a and those made of mesh fabric material The translucent blades 2b rotate in conjunction with each other in different phases.

[0078] (2) By adjusting the gear ratio of each gear mechanism 8, the rotation speed of the mutually independent translucent blades 2b is made larger than the rotation speed of the light-shielding blades 2a. After the second blade hanger 14b contacts the first blade hanger 14a, the light-shielding blade 2a and the translucent blade 2b rotate while maintaining the contact state of the two. Therefore, by increasing the rotation speed difference, the translucent blade 2b is in close contact with the light shielding blade 2a at an earlier stage.

[0079] (3) While both ends of the translucent blad...

[0167] The sixth embodiment can be modified as follows.

[0168] The ratio of the rotation angle (rotation speed) of the left blade group G1 and the right blade group G2 need not be 1:2.

[0169] The first to third blade groups can be set. In other words, a left blade group, a middle blade group, and a right blade group can be provided. The rotation speed of the middle blade group may be different from the rotation speed of the left blade group or the right blade group.

Abstract

A plurality of runners (3) are capable of moving along a hanger rail (1). A first slat (2a) or a second slat (2b) is hung down from and supported by a hanging shaft (6) that is rotatably supported by the runner (3). A gear mechanism (8) transmits rotation of a tilt shaft (4) to each hanging shaft (6) to rotate the slat (2a, 2b). The gear ratio of the gear mechanism (8) corresponding to the first slat (2a) is set to be different from the gear ratio of the gear mechanism (8) corresponding to the second slat (2b). Therefore, in the blind, the angle of the slats (2a, 2b) can be adjusted at different speeds and in conjunction with each other.

Description

Technical field [0001] The invention relates to a louver capable of adjusting multiple blade angles at different speeds. Background technique [0002] The vertical blind has a hanging rail, a plurality of runners movable along the hanging rail, and a plurality of blades, and each of the plurality of blades hangs down from and supported by each of the traveling members. The blades are unfolded and folded along the hanging rail, and the angle of each blade is adjusted to adjust the amount of light entering the room through the vertical blinds. The material of the blade has light-shielding properties. [0003] The user rotates the operating lever (operating mechanism) or pulls the operating rope to adjust the angle of the blade in the same phase. Therefore, according to the angle of the blade, the room is completely visible from the outside. Even if the light-shielding blades and translucent blades made of, for example, a mesh fabric alternately hang down from the hanging rail and a...
