By the way, in the blind device, a plurality of blades stacked and bundled on top of each other so that sufficient lighting can be obtained when necessary without fully obstructing the view from the window when the window is fully opened. It is preferable to be arranged on the ceiling side without largely covering, but due to the space occupied by the blade lifting device and blade tilting means, the upper part of the window is made up of these bundled blades unless the ceiling is raised. May be covered greatly. Further, in the blind device, since the tilting of the plurality of blades by the tilting means is performed around the fixed rotation axis with respect to the front-rear direction of the blades, the leading edge portion of the blades protrudes forward, It is difficult to make the blind device itself and its installation area compact.

  In order to solve such problems, for example, in Patent Document 2, a plurality of blades juxtaposed in the vertical direction, a link mechanism that interconnects the plurality of blades, and the lowest blade of the plurality of blades And an elevating mechanism that elevates and lowers from the blade, and a tilting means that is arranged behind the vane and tilts the plurality of vanes based on the elevating and lowering of the vane by the elevating mechanism. A blade support mechanism that supports the uppermost blade so as to be rotatable and movable in the front-rear direction, and the uppermost blade rotates to the uppermost blade at the rear edge portion behind the portion supported by the blade support mechanism. The wing is tilted by the relative displacement in the vertical direction of the trailing edge of the blade with respect to the portion that is freely connected and supported by the blade support mechanism in the uppermost blade. And a moving mechanism that moves the trailing edge in the vertical direction based on the lifting and lowering of the blade by the lifting mechanism, and the blade support mechanism supports the uppermost blade so as to be rotatable and movable in the front-rear direction. It has a blade support member, and the moving mechanism is linearly movable in the vertical direction in which the uppermost blade is rotatably connected to the rear edge portion behind the portion supported by the blade support member. And a transmission mechanism for releasably transmitting the operation of the elevating mechanism to the linearly movable member so as to linearly move the linearly movable member vertically. The elevating mechanism moves the plurality of blades up and down. The transmission mechanism includes a rack and pinion mechanism that applies direct power in the vertical direction to the linearly movable member based on the rotation of the rotation shaft, and transmits the rotation of the rotation shaft to the rack and pinion mechanism. On the other hand, more than a predetermined rotational load A sliding mechanism for releasing the transmission of the rotation by causing a slip on the rotating shaft when it occurs, and a linear motion prohibiting mechanism for prohibiting the linear motion upward from a predetermined position of the linear motion member so as to be releasable. A blind device has been proposed.
