According to the louver device of Patent Document 2, referring to FIG. 13A, the curl 111a formed on the side of the louver 111 improves the bending strength in the longitudinal direction, but FIG. Referring to it, there is a problem that the bending strength in the width direction is not improved.

  According to the louver devices of Patent Documents 1 to 4, since the louver is fixed, there is a problem that the louver cannot be rotated and the entire plurality of louvers cannot be stacked. In particular, according to the louver devices of Patent Documents 3 and 4, there is a problem that it is difficult to achieve rotation and lamination because the shape of the louver is complicated.

  According to the louver device of Patent Document 5, the plurality of louver rotation shafts are fixed to the openings, respectively, and the entire shape of the louvers is complicated, so that the entire plurality of louvers cannot be stacked.

  In a first aspect, the present invention provides a louver device having a plurality of angle members arranged in parallel in an opening. The plurality of angle members are rotated about the longitudinal direction as a central axis to change the aperture ratio of the opening. The plurality of angle members move in a direction perpendicular to the longitudinal direction and can be extended and stacked. Each of the plurality of angle members includes one surface that can block solar radiation, and another surface that can simultaneously block the line of sight when the one surface blocks solar radiation.

The effect of the louver apparatus by this invention is illustrated.
(1) Since each louver of the louver device is basically composed of an angle member having an L-shaped cross section, the bending strength is improved not only in the longitudinal direction of the fin but also in the width direction. Therefore, the louver device of the present invention has excellent wind resistance and is suitable for outdoor use.
(2) By using both of the two surfaces of the angle member at the same time, it is possible to simultaneously block the solar radiation from above and the line of sight from below with a predetermined opening ratio that allows ventilation. Therefore, according to the present invention, the solar radiation shielding function and the blinding function in all directions can be exhibited simultaneously with a predetermined aperture ratio as compared with the case where the louver is in the shape of a strip.
(3) Since the angle member serving as the louver basically has a simple and simple shape having an L-shaped cross section, it can be easily rotated or stacked on each other.
(4) Since each louver of the louver device is composed of angle members that can be rotated and stacked on each other, the user can rotate the angle members according to the indoor / outdoor temperature, the intensity of sunlight, or the strength of the wind. Thus, by adjusting the aperture ratio of the opening or stacking a plurality of angle members, it is possible to adjust lighting or the like.
(5) Since a three-dimensional pattern or shadow is formed by combining a plurality of angle members having a simple shape, high decorativeness is added to the louver device. In particular, even when the louver device is closed, the repetitive pattern composed of protruding corners and recessed sides of the angle member reduces the feeling of pressure due to closing.
(6) The angle member is less expensive because it is used more widely than the band plate. Therefore, the louver device of the present invention can be manufactured at a lower cost than a louver device using a large number of strips.
