The present invention relates to a louver device that is disposed in a window of a building to shield the room from light and to block light.

There is known a louver device in which a plurality of blades (slats) are arranged in a vertical direction in a window of a building, and the indoors are covered by lifting and tilting movement of the blades, and natural light or artificial light is performed. In the light shielding, for example, Patent Document 1 proposes a louver device provided with a lifting device for lifting a blade and a tilting moving device (tilting mechanism) for tilting the blade. Regardless of the louver device provided on the indoor side or the outdoor side, when the window is completely opened, a plurality of blades that are generally overlapped and bundled are disposed on the ceiling side. Further, the louver device is preferably such that a plurality of blades bundled to overlap each other are disposed on the ceiling side so as not to largely cover the upper portion of the window, so that when the window is completely opened, the view from the window is not hindered. Sufficient daylighting can be obtained, but there is a possibility that the space occupied by the tilting device of the blade or the tilting movement of the blade, if the ceiling is not increased, the upper portion of the window is substantially covered by the bundle of the plurality of blades. Further, the louver device is moved in the front-rear direction of the blade by the inclination of the plurality of blades of the tilting moving device, and is centered on the fixed rotating shaft, so that the leading edge portion of the blade protrudes forward, and as a result, it is difficult to find the louver device itself and Set the area to be miniaturized.

In order to solve this problem, for example, Patent Document 2 proposes a louver device including: a plurality of blades which are arranged side by side in the up and down direction; a plurality of blades connected to each other; a lifting mechanism that lifts and descends from a lowermost one of the plurality of blades; and a tilting moving device disposed behind the blade and based on lifting of the blade using the lifting mechanism And moving the plurality of blades obliquely; the tilting moving device is provided; the blade supporting mechanism rotatably and freely supporting the uppermost one of the plurality of blades in the front-rear direction; and the moving mechanism, which is at the uppermost position a rear edge portion of the blade that is supported by the blade support mechanism, is rotatably coupled to the uppermost blade, and is supported by the blade support mechanism by the trailing edge portion of the blade relative to the uppermost blade The relative displacement of the support portion above and below the upward movement causes the blade to move obliquely, and the trailing edge portion of the blade moves in the up and down direction based on the lifting and lowering of the blade by the lifting mechanism; the blade supporting mechanism is provided with the blade supporting member, which is freely rotatable And the uppermost blade is freely supported in the front-rear direction, and the moving mechanism has: linear motion from a member that is rotatably coupled to a portion of the uppermost blade that is supported by the blade support member and has a rearward trailing edge portion that is linearly movable in the up and down direction; and a conveying mechanism that allows the linear motion to be freely movable The linear motion in the direction causes the lifting mechanism to be freely transmitted to the linear motion free member; the lifting mechanism includes a rotating shaft that rotates in order to move the plurality of blades up and down, and the transmitting mechanism includes a rack and pinion mechanism based on the rotating shaft Rotation, which imparts a linear motion force to the linear motion free member; the sliding mechanism transmits the rotation of the rotary shaft to the rack and pinion mechanism, and on the other hand, when a specific rotation load is generated, a relative rotation axis is generated. The sliding is released to release the above-described rotation; and the linear motion prohibiting mechanism is free to prohibit linear motion that is more upward toward a specific position of the relatively linear motion free member.
