As shown in the figure, most of the blind devices 100 for ordinary houses and office buildings have blades 101... The blades 101 are formed of a foil-like resin plate or the like, and the blades 101 are suspended downward from the upper frame 102 while being connected to each other via vertical strings 103 for opening and closing. Since the blades 101 are foil-shaped resin plates or light metal plates as described above, it is difficult to obtain high rigidity, and they are usually supported by vertical strings 103 at intervals of about 500 mm to prevent bending. Reference numeral 104 denotes an operation string for a blind opening / closing operation.

According to the present invention, the following effects are exhibited by the above configuration. Claim 1 is a blind, wherein the blind is supported between frames provided on both sides via a support shaft, tension is applied in a length direction, and a plurality of foil members provided vertically are provided. A driven rotating member provided on each support shaft of each blade, for rotating each blade from a horizontal state to an inclined or vertical state, and a driving member for rotating the driven rotated member.

According to the first aspect, since the blade is tensioned in the length direction, the middle portion of the blade does not bend, and
Therefore, the warp and the weft for securing the rigidity of the blade are unnecessary.
In addition, the blade is only rotated by a rotating member and a driving member that drives the blade, and a plurality of vertical cords arranged in the length direction of the blade for rotating the blade which causes protrusion are completely separated from the blade. As a result, the structure can be simplified, the number of parts can be reduced, and the rotation operation can be performed smoothly and reliably.

Further, since there is no vertical cord that causes protrusion, the thickness before and after the blind is extremely small, and the structure of the rotating member provided at both ends of the blade and the driving member for driving the rotating member is employed. When incorporated in a double-layer glass, the thickness of the double-layer glass can be reduced. Therefore, it is possible to fit a double-glazing unit having a built-in blind into a groove of an existing sash. Further, since the rotating member provided on the support shaft of the blade is rotationally driven by the driving member to shift the blade to the horizontal, inclined, and vertical states, the opening and closing mechanism of the blade and the opening and closing driving mechanism can be simplified.

According to a second aspect, in the first aspect, the driven rotating member provided on each support shaft of each blade is a driven gear, and an intermediate gear is interposed between the driven gears arranged vertically, and a gear is provided. Of these, the highest or lowest one is driven by a drive gear, and the driven gears are driven to rotate in conjunction with each other.
