  However, it has been difficult to capture sunlight into the room depending on the sunlight irradiation angle. In particular, when a balcony protruding from the second floor is provided above the opening on the first floor, the balcony itself hinders the intake of sunlight, making it even more difficult to capture sunlight into the first-floor room I was trying.

  In addition, when a building is built in the adjacent land without securing a sufficient interval from the opening of the building, the building built in the adjacent ground prevents the sunlight from being taken into the first floor, and the first floor is It was difficult to capture enough sunlight. In particular, there are many cases where buildings can be built on the adjacent land with only a distance of about 4m from the opening of the building due to restrictions on the building site and coverage ratio. There were many.

  Even when a light shelf is used, it is difficult to obtain a sufficient lighting effect due to the situation of the building in the neighboring land and the presence or absence of a balcony. There were many problems in the use of the light shelf.

  In view of the above problems, the present invention has a balcony on the upper floor of the opening of a building without being affected by the irradiation angle of sunlight, or there is a shielding object such as a building on the adjacent ground. Even so, an object of the present invention is to provide a daylighting apparatus that can take sunlight into the living room on the first floor.

  The above problem is that a light transmission diffusion plate that transmits and diffuses sunlight is vertically attached to the upper side of the opening on the outdoor side of the wall surface having the opening of the building, and the sunlight passes through the light transmission diffusion plate indoors. It is solved by a daylighting device characterized in that it is taken in.

  In this daylighting apparatus, a light transmission diffusion plate that transmits and diffuses sunlight is vertically attached to the upper side of the opening on the outdoor side of the wall surface having the opening of the building, and the sunlight incident on the light transmission diffusion plate Since light is refracted and taken indoors through the light transmissive diffuser, it has a balcony on the upper floor of the building opening without being affected by the sunlight irradiation angle, Even if there is a shield such as a building, sunlight can be taken into the living room on the first floor.

  In the above daylighting apparatus, the daylighting apparatus may be attached to a bottom surface of a balcony provided on the upper floor having an opening.

  Using a balcony provided on the upper floor of the floor that has an opening that restricts the intake of sunlight into the living room on the first floor, attach the lighting device vertically above the opening The sunlight can be taken into the first-floor room, and the sunlight is taken into the first-floor room while having a balcony that restricts the taking of sunlight into the first-floor room. Can do. Further, even in an existing building, there is no need to newly install a frame or the like in the building in order to attach the daylighting device, and the daylighting device can be attached using the existing balcony.

  In addition, if the daylighting device attached to the bottom of the balcony can be folded, the use of the daylighting device can be selected according to the irradiation angle of the sunlight depending on the season and time, and the optimum sunlight can be captured. can do.

  Furthermore, it is preferable that the indoor side of the light transmission diffusion plate has a saw blade shape.

  By making the indoor side of the light transmissive diffusion plate into a saw blade, sunlight taken from the outdoor side is refracted in multiple stages by the saw blade on the indoor side of the light transmissive diffusion plate, and the sunlight is radiated inside the room. It is possible to capture to the far side.

  In addition, if a flat plate that transmits light is provided on the indoor side of the light transmission diffusion plate, the unevenness on the saw blade on the indoor side of the light transmission diffusion plate is covered with the flat plate, so the saw blade of the light transmission diffusion plate It is possible to prevent dust and the like from accumulating or getting dirty, and it is possible to reduce maintenance work even though it is a daylighting device installed outdoors that is easily contaminated.

  Since the present invention is as described above, the daylighting apparatus has a balcony on the upper floor of the opening of the building without being affected by the irradiation angle of sunlight, or a shielding object such as a building is adjacent to the ground. Even if there is, sunlight can be taken into the living room on the first floor.

  Next, embodiments of the present invention will be described with reference to the drawings.

  A daylighting apparatus 1 according to an embodiment of the present invention shown in FIG. 1 is attached to a bottom surface portion 12a of a balcony 12 provided continuously to a two-story room 7 outside a two-story room 7 of a two-story building. It consists of a folding type light transmission diffusion plate 2. The light transmission diffuser plate 2 is attached to the bottom surface of the outdoor side end portion of the balcony via a hinge 5 so as to be rotatable around the hinge 5 and provided at both ends of the light transmission diffuser plate 2 in the balcony width direction. It is held by holders 6 and 6 having a fulcrum for bending at the center and fulcrums for rotation at both ends. As shown in FIG. 1 (d), the daylighting apparatus 1 from the open state where it vertically hangs down from the lower end of the balcony 12 by means of the holders 6 and 6 having a fulcrum for bending at the center and pivots at both ends, It can be switched to a folded state that is horizontal along the bottom surface of the balcony 12.

  As shown in FIG. 1 (c), the light transmission diffuser plate 2 is attached to the building, and one surface on the outdoor side with respect to the building is planar, and the other surface on the indoor side is the upper side. From the top to the bottom, it has a saw-tooth shape that repeats peaks and valleys sequentially. Further, a flat plate 3 that transmits light is provided on the outdoor side of the light transmission diffusion plate 2 via a spacer 4. The light transmissive diffusion plate 2 and the flat plate 3 may be anything as long as they transmit and diffuse light. For example, a resin material such as an acrylic plate or a ceramic material such as glass may be used. It may be good, other things, or any combination. Moreover, there is no restriction | limiting in the manufacturing method.

  As shown in FIG. 2 (a), for example, in this embodiment, there is an adjacent boundary line 13 at a position 3000 mm away from the outer wall surface of the building, and an adjacent building 14 is built at a position 1100 mm away from the adjacent boundary line 13. An opening 9 having a height of 400 mm from the GL to the FL and a height of 2000 mm from the first floor level is provided, and the distance from the first floor hanging wall 10, that is, the upper end of the opening to the bottom of the balcony is 400 mm. In the case where the protruding dimension of the balcony is 1000 mm, if the hanging length of the light transmission diffuser plate of the lighting device from the bottom surface of the balcony is about 450 mm, the sunlight is effectively sent to the first-floor room 8 of the building by the lighting device. Can be captured. In addition, the eaves height of the adjacent building is 6300 mm.

  As shown in FIG. 3A, when the daylighting device 1 is mounted on the bottom surface of the outdoor side end of the balcony 12, the sunlight irradiation angle is high due to the diffusion of light by the daylighting device 1, and the balcony is lowered. However, even in a situation where it is difficult to capture the sunlight where the border is adjacent to the adjacent land, the sunlight can be guided into the first-floor room. On the other hand, as shown in FIG. 3 (b), when this daylighting measure 1 is not attached, the entrance of sunlight is blocked by the balcony 12 and the adjacent land, and the light cannot be almost taken into the first-floor room. In addition, sunlight can be taken in only during a part of the year.
