Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a daylighting device that is easy to operate and can effectively control sunlight introduced into a room in accordance with the solar altitude.

Conventionally, this type of daylighting device usually involves providing a lighting area near a window, for example, or by hanging a blind to control the incident light according to changes in the solar altitude. In the former case, if the control is performed every time the solar altitude changes using the 54 Niruba, the operation becomes extremely cumbersome, and in the case of blinds, fine angle adjustments are required, so this also becomes cumbersome. Additionally, these devices have the disadvantage of requiring complex adjustment mechanisms.

The present invention has been made in order to eliminate the above-mentioned drawbacks. By installing an integrally molded louver body having a large number of louver pieces, the angle of the louver body together with the frame body can be changed according to the solar altitude, making control operations easier.
Moreover, the purpose is to provide a second lighting system so that effective light can be introduced into the room.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed embodiment of the present invention will be described. Referring to the drawings, (1) is a lighting part such as a window, and (2) is a transparent window glass. (3) is a frame body formed in the shape of a flat case and arranged inside the window glass (2) on the upper side ζ of the lighting section (1), and protrudes from approximately the center of both end faces of the frame body. It has a supporting shaft (4) (4), and this supporting shaft (4)
(4) is placed in close contact with the wall surface (1a) of the lighting section (1) in the support frame (5). A transparent member (7) like glass is stretched. (8) is the looper body.
The inner surface of the frame (3) (2 plates to be attached) are formed, one side of which is cut and raised 6: thus formed a large number of louver pieces (9) (9) ---.・(9) is provided. That is, the louver piece (9) has an inclination angle of 70" from the vertical plane and protrudes downward. αIQI is a circularly protruding retainer. and the support frame (
5) Fan-shaped (=formed recess aυaυ'al)'
- Two selective bows can be combined (two. Q3 indicates the ceiling surface.

Next, we will discuss two effects ζ. The IJ1 diagram shows the state of the frame (3) in the spring and autumn seasons (for example, when the solar altitude is mid-heaven). In this case, the engaging part 01 of the frame (3) is the supporting frame (5) f) Concave m (1m)' 4-position RL Te 1t
, 1!15 (1) t: For te vertical < 2 is held. Therefore, sunlight entering from the daylighting part (1) passes through one transparent member (7) to the louver piece (8) of the louver body (8).
9), it can be reflected to the ceiling surface α through the other transparent member (7) as shown in FIG. 6 (A) (=), brightening the room. If the sun altitude is high, use appropriate manual operation to tilt the frame (3) clockwise as shown by the dotted line (A) in Figure 5 to position the engaging portion Ql in the recess ar. Same as above (2 sunlight can be reflected as shown in Figure 6 (B) (2) and illuminate the ceiling surface a3 in the same way. Also, when the sun altitude is low like in winter, the above is different. Reverse (Part 2, Figure 5)
By tilting and positioning the engagement sQI in the recess αD4 as shown in FIG. 6(C), the ceiling surface a3 (=
On the other hand, the room can be illuminated with the same reflection angle as the former.

As described in detail above, the present invention has (2) a built-in structure C; a formed lighting section, a frame body tiltably disposed in the lighting section, and a louver piece integrally formed in the frame section C; Since the daylighting device is equipped with a frame body and a louver body whose angle is variable, the angle of reflection of sunlight entering the room through the daylighting area can be controlled in accordance with the solar altitude. It has the advantage of being able to always provide effective introductory light and lighting the room.

In addition, variable operation is extremely easy, and since the louver pieces are integrally molded, they also have the advantage of being easy to clean.
