As shown in FIG. 4, the positioning clip 10 is formed by bending a single rectangular leaf spring member at five locations, a bottom portion 10a, a pair of pressing portions 10b, 10b, a pair of contact portions 10c, 10c, and a pair of force points. It is formed (folded) by forming the portions 10d and 10d. The positioning clip 10 is bent symmetrically with respect to the bottom 10a.
The bottom portion 10a and the pressing portion 10b form an obtuse angle, the pressing portion 10b and the contact portion 10c form a substantially vertical angle, and the contact portion 10c and the force point portion 10d form an acute angle.

The bottom portion 10a has a curved shape.
The pressing portion 10b extends upward from the side edge of the bottom portion 10a. The pressing portion 10b is bent so as to be parallel to the side surface portion 30b of the rail member 30 (see FIG. 5B). The left and right pressing portions 10b, 10b face each other in an inverted C shape. Further, an anti-slip rubber sheet 10e is attached to the outer surface of the pressing portion 10b. When the positioning clip 10 is set at a desired position of the rail member 30, the rubber sheet 10e contacts (surface contact) with the side surface portion 30b of the rail member 30, and the positioning clip 10 moves from the desired position. To prevent it.
Note that the length of the pressing portion 10b in the vertical direction is such that when the positioning clip 10 is inserted into the rail member 30, the contact portion 10c comes into contact (surface contact) with the engagement portion 30f of the rail member 30. It has been adjusted (see FIG. 5B).

  The contact portion 10c extends from the upper end of the pressing portion 10b toward the inside (the center side of the positioning clip 10).

  The force point portion 10d extends upward from the inside of the contact portion 10c. The left and right force point portions 10d, 10d face each other in an inverted C shape. A through hole 10f penetrating in the plate thickness direction is formed in one of the pair of force point portions 10d (in this embodiment, the force point portion 10d on the left side of FIG. 4). The ring-shaped member 11b of the connecting member 11 is inserted through the through hole 10f (see FIG. 3).

2 and 3, the rail member 30 is attached to the lower portion 7 along the groove 71, and a bottom surface 30a extending along the longitudinal direction of the groove 71, and both side edges of the bottom surface 30a. It is mainly comprised from a pair of side part 30b, 30b extended toward upper direction from the upper part, and a pair of flange part 30c, 30c extended toward the side from the upper end of the side part 30b.
The bottom surface portion 30a, the side surface portion 30b, and the flange portion 30c are integrally formed.

  The bottom surface portion 30 a has a substantially rectangular shape in plan view, and is provided along the bottom surface of the groove portion 71. The outer surface of the bottom surface portion 30 a is in close contact with the bottom surface (inner surface) of the groove portion 71.

  The side surface portions 30b and 30b are formed in a cross-section inverted C shape across the bottom surface portion 30a, and are provided along the side surface of the groove portion 71. The outer surface of the side surface portion 30 b is in close contact with the side surface (inner surface) of the groove portion 71.

  The rail member 30 is formed with a space portion 30d surrounded by a bottom surface portion 30a and a side surface portion 30b. The positioning clip 10 is inserted into the space 30d (see FIG. 5B).

The flange portion 30 c has a rectangular shape in plan view, and extends in the longitudinal direction of the groove portion 71 along the upper surface of the lower portion 7. The flange portion 30 c is mechanically fixed to the lower portion 7 by screwing in a state where the flange portion 30 c is in contact with the upper surface of the lower portion 7. Further, the flange portion 30c is formed with an engaging portion 30f that covers a part of the space portion 30d from above.
The engaging portion 30f is formed by extending one end of the flange portion 30c in the short direction from the upper end of the side surface portion 30b to the inside (center side of the rail member 30). Thereby, it is possible to prevent the positioning clip 10 from coming out from above the rail member 30.
An opening 30e penetrating in the vertical direction is formed between the engaging portions 30f and 30f. As a result, the positioning clip 10 can be inserted into the space 30d.

  Next, a method of fixing the positioning clip 10 will be described with reference to FIGS. 5 (a) and 5 (b).

As shown in FIG. 5A, when both of the force application points 10d and 10d are pressed inward (center side of the positioning clip 10), the force application parts 10d and 10d approach each other, and the contact part is interlocked with this. 10c and 10c approach, and also the pressing parts 10b and 10b approach.
Then, the force application point 10d is pressed to the extent that the positioning clip 10 can be inserted into the opening 30e of the rail member 30, and the approaching positioning clip 10 is inserted into the space 30d from the opening 30e.
The positioning clip 10 is inserted into the space 30d, and when the bottom portion 10a of the positioning clip 10 comes into contact with the bottom surface portion 30a of the rail member 30, the pressure applied to the force point portion 10d is released. At this time, only a part of the power point portion 10d is exposed from the opening 30e.
When the pressure applied to both the force application points 10d and 10d is released, the force application points 10d and 10d are separated from each other, and the contact parts 10c and 10c are separated from each other in conjunction with the force application parts 10d and 10d. (See FIG. 5B). Then, the outer surface of the rubber sheet 10e adhered to the pressing portion 10b abuts (surface contact) with the side surface portion 30b of the rail member 30, and due to the elasticity of the bent portion at the boundary between the bottom portion 10a and the pressing portion 10b, The pressing portion 10b presses the side surface portion 30b through the rubber sheet 10e (see FIG. 5B).
Relative movement of the positioning clip 10 relative to the rail member 30 can be reliably prevented by the elasticity of the bent portion at the boundary between the bottom portion 10a and the pressing portion 10b and the rubber sheet 10e.
The abutting portion 10 c abuts (surface contact) with the lower surface of the engaging portion 30 f of the rail member 30.
Thereby, it is possible to prevent the positioning clip 10 inserted into the space portion 30d from slipping out from above the rail member 30.
In this way, with the bottom portion 10a, the pressing portion 10b, the contact portion 10c, and a part of the force point portion 10d inserted into the space portion 30d (see FIG. 5B), the pressing portion 10b presses the side surface portion 30b. Then, the positioning clip 10 is fixed to the rail member 30 by the contact portion 10c being in contact (surface contact) with the engagement portion 30f.

  When removing the positioning clip 10 from the rail member 30, the force point portion 10d is pressed to such an extent that it can be extracted from the opening 30e, and the contracted positioning clip 10 is extracted from the space 30d and the opening 30e.

Next, the angle adjusting operation of the reflecting member 4 will be described with reference to FIGS.
In a state where the reflecting member 4 is pulled out and no external force is applied, the pulled-out reflecting member 4 stops in a state parallel to the window portion 9. Therefore, when the positioning clip 10 is engaged with a position closer to the indoor side of the rail member 30, the angle θ formed by the reflecting member 4 and the window portion 9 increases (see FIG. 2), and the positioning clip 10 is moved to the rail member 30. Is engaged with a location closer to the outdoor side, the angle θ becomes smaller (see FIG. 6).
That is, when the engagement position between the positioning clip 10 and the rail member 30 is changed from the indoor side to the outdoor side, the angle θ formed by the reflecting member 4 and the window portion 9 gradually decreases, and conversely, the positioning clip As the engagement position between the rail 10 and the rail member 30 is changed from the outdoor side to the indoor side, the angle θ formed by the reflecting member 4 and the window portion 9 increases gradually.
That is, by changing the position of the positioning clip 10 on the rail member 30, the inclination of the reflecting member 4 can be freely changed.

Next, the winding and pulling-out operation (opening / closing operation) of the reflecting member 4 will be described with reference to FIGS.
The positioning clip 10 is removed from the rail member 30 from the state in which the reflecting member 4 (screen 44) is pulled out to the vicinity of the lower portion 7 (see FIG. 2), and the operation shaft is operated to operate the winding shaft 43 in the screen winding direction. When it is rotated, the reflecting member 4 is wound around the winding shaft 43, and the reflecting member 4 and the weight bar 45 are raised (see FIG. 7A).
Further, when the operation chain is operated to rotate the winding shaft 43 in the screen winding direction, the reflecting member 4 is completely wound around the winding shaft 43 (see FIG. 7B).

On the other hand, when the reflecting member 4 is wound around the winding shaft 43 (see FIG. 7B), when the operating chain is operated and the winding shaft 43 is rotated in the screen drawing direction, the reflection from the winding shaft 43 is reflected. The member 4 is pulled out, and the reflecting member 4 and the weight bar 45 are lowered (see FIG. 7A).
Further, when the operating chain is operated to rotate the winding shaft 43 in the screen drawing direction, the reflecting member 4 is pulled out to the vicinity of the lower portion 7 (see FIG. 2).
Thus, since the reflection member 4 of this embodiment is provided so that winding and extraction are possible, it can reflect the sunlight from the opening part 6a for lighting.

According to the bay window daylighting apparatus 1 according to the first embodiment described above, the daylighting opening 6a is formed in the upper part 6, and the reflecting member 4 is disposed below the daylighting opening 6a, so that it is used for daylighting. Since sunlight incident from the opening 6a is reflected indoors, the sunlight can be efficiently guided indoors.
In addition, a rail member 30 is provided at the lower portion 7, and a positioning clip 10 that can be engaged with the rail member 30 via the connecting member 11 is provided at the lower end of the reflecting member 4, and the rail member 30, the positioning clip 10, The angle θ of the reflecting member 4 with respect to the window portion 9 (the angle θ formed between the reflecting member 4 and the window portion 9) can be adjusted by changing the engagement position of the light, so that the sunlight incident from the lighting opening 6a can be adjusted. The amount of light collected can be adjusted.

In addition, the lid 6b can cover the daylighting opening 6a so as to be openable and closable, and the reflection member 4 is provided so that it can be wound and pulled out.
In addition, in the situation where direct sunlight hits the window portion 9, when it is desired to take sunlight into the room, the reflecting member 4 is wound up so that the window portion 9 is not covered, and the sunlight hitting the window portion 9 can enter the room as it is. . Further, when it is not desired to take sunlight into the room, the sunlight released from the lighting opening 6a is obtained by covering the lighting opening 6a with the lid 6b and covering the window 9 by pulling out the reflecting member 4. While blocking | interrupting light, the sunlight which hits the window part 9 can be shielded.

  On the other hand, in the situation where direct sunlight does not hit the window portion 9, when it is desired to take sunlight into the room, the light opening 6 a is not covered with the lid portion 6 b, and the reflection member 4 is pulled out to cover the window portion 9. That is, the sunlight 6 emitted from the lighting opening 6a toward the window 9 is indoors by pulling out the reflecting member 4 and covering the window 9 without covering the lighting opening 6a with the lid 6b. It can be reflected toward. If it is not desired to take sunlight into the room, the lid 6b covers the daylighting opening 6a, and the reflection member 4 is pulled out to cover the window 9. That is, while covering the opening 6a for lighting with the cover part 6b and covering the window part 9 by pulling out the reflecting member 4, the sunlight emitted from the opening part 6a for lighting is cut off and from the window part 9 Incident sunlight (diffused light) can be shielded.

  Further, when sunlight is taken indoors in a situation where direct sunlight does not hit the window portion 9, it is possible to adjust the amount of light collected without adjusting the angle of the reflecting member 4. That is, if the lighting opening 6a and the window 9 are not covered, the amount of sunlight entering the room can be reduced compared to the case where the lighting opening 6a is not covered and the window 9 is covered. it can. Further, if the lighting opening 6a is covered and the window 9 is not covered, the amount of sunlight entering the room is reduced as compared with the case where the lighting opening 6a and the window 9 are not covered. be able to.

  Further, by winding up the reflecting member 4, it is possible to ensure the view from the window portion 9 and the air permeability of the window portion 9. For example, in a situation where direct sunlight does not hit the window 9, when it is desired to take sunlight into the room, if the reflecting member 4 is positioned at the center in the vertical direction of the window 9, the viewability from the window 9 and the window The sunlight incident from the daylighting opening 6a can be efficiently guided indoors while ensuring the air permeability of 9 (see FIG. 7A).

  Moreover, since the reflecting member 4 is installed so that the side portion 8 can be ventilated, the sunlight incident from the daylighting opening 6a is efficiently guided indoors while ensuring the ventilation property of the side portion 8. be able to.

  Moreover, since the reflecting surface of the reflecting member 4 is composed of a diffuse reflecting surface, the sunlight reflected by the diffuse reflecting surface spreads uniformly toward the room, so that unevenness of sunlight can be suppressed.

  In addition, the reflecting surface of the reflecting member 4 is made of a metal material, a resin material, a fiber material, or a composite material of a metal material and a resin material, which has a particularly high reflectivity, so that it is introduced from the daylighting opening 6a. The sunlight can be led to the room without significant attenuation.

  Further, since the light duct 3 is connected to the daylighting opening 6a, sunlight can be guided to a dark place in the building T where the sun does not reach, and stable brightness can be ensured.

  Moreover, the optical duct 3 is attached to the outer wall of the building T, and can be easily installed in the existing building. That is, since the optical duct 3 can be attached to the outer wall of the building T, it can be installed in an existing building.

If it does in this way, since the raising / lowering cord (illustration omitted) can be operated and the reflection member 4 can be raised / lowered, the freedom degree of lighting increases like this embodiment.
In addition, in the situation where direct sunlight hits the window portion 9, when it is desired to take sunlight into the room, the reflecting member 4 is lifted so as not to cover the window portion 9, and the sunlight hitting the window portion 9 can be directly incident on the room. . When it is not desired to take sunlight into the room, the lighting opening 6a is covered with the lid 6b, and the reflecting member 4 is lowered to cover the window 9 so that the light is emitted from the lighting opening 6a. While blocking sunlight, the sunlight which hits the window part 9 can be shielded.

  On the other hand, in a situation where direct sunlight does not hit the window 9, when it is desired to take sunlight into the room, the lid 6 b does not cover the daylighting opening 6 a, and the reflecting member 4 is lowered to cover the window 9. . In other words, the sunlight 6 emitted from the lighting opening 6a toward the window 9 is indoors by lowering the reflecting member 4 and covering the window 9 without covering the lighting opening 6a with the lid 6b. It can be reflected toward. When it is not desired to take sunlight into the room, the lid 6b covers the daylighting opening 6a, and the reflecting member 4 is lowered to cover the window 9. That is, while covering the opening part 6a for lighting with the cover part 6b, the reflecting member 4 is lowered | hung and the window part 9 is covered, while blocking | blocking the sunlight radiated | emitted from the opening part 6a for lighting, and the window part 9 The sunlight (diffused light) that enters from can be shielded.

  Further, when sunlight is taken indoors in a situation where direct sunlight does not hit the window portion 9, it is possible to adjust the amount of light collected without adjusting the angle of the reflecting member 4.

Further, if the lighting opening 6a is covered and the window 9 is not covered, the amount of sunlight entering the room is reduced as compared with the case where the lighting opening 6a and the window 9 are not covered. be able to.

Further, by raising the reflecting member 4, it is possible to ensure the view from the window portion 9 and the air permeability of the window portion 9. For example, in a situation where direct sunlight does not hit the window 9, when it is desired to take sunlight into the room, if the reflecting member 4 is positioned at the center in the vertical direction of the window 9, the viewability from the window 9 and the window 9 can be efficiently guided indoors while ensuring air permeability of 9.
Further, when the reflecting member 4 is formed by providing a reflecting surface on the slat 4a, the angle of the plurality of slats 4a, 4a,... Can be adjusted by the operation rod 4b. The light can be reliably guided into the room. Further, by adjusting the angle of the slat 4a to form a gap between the slats 4a, the viewability from the window 9 and the ventilation of the window 9 are maintained while the reflecting member 4 is lowered to the vicinity of the lower portion 7. Can be secured.

  Next, modified examples of the groove and the angle adjusting mechanism will be described with reference to FIGS.

  As shown in FIG. 12, the groove portion 72 according to the modified example has a rectangular shape in a sectional view, and is formed in a direction intersecting the reflecting member 4 (orthogonal direction).

  As shown in FIG. 12, the angle adjustment mechanism A according to the modification mainly includes a positioning hook 20 and a fixing member 40.

  As shown in FIG. 13, the positioning hook 20 is mainly composed of a base portion 20a and a protruding portion 20b. As shown in FIG. 12, the positioning hook 20 is connected to the reflecting member 4 via the connecting member 11.

  The base 20a has a cylindrical shape. The height of the base 20a is smaller than the depth of the groove 72, and the diameter of the base 20a is smaller than the width of the groove 72 (see FIG. 14C). Therefore, the entire base portion 20 a can be inserted into the groove portion 72.

  The protruding portion 20b is formed to protrude upward from the central portion of the base portion 20a. Moreover, the through-hole 20c penetrated in the horizontal direction is formed in the front-end | tip side of the protrusion part 20b. The ring-shaped member 11b of the connecting member 11 is inserted through the through hole 20c.

  As shown in FIG. 12, the fixing member 40 is a thin plate-like member having a rectangular shape in plan view, and is formed of a material such as metal, wood, or synthetic resin. The fixing member 40 is provided along the longitudinal direction of the groove portion 72 so as to cover the opening surface of the groove portion 72 from above. The fixing member 40 is mechanically fixed to the lower portion 7 by screwing in a state where both ends in the short direction are in contact with the upper surface of the lower portion 7. Further, the fixing member 40 is formed with a plurality of through holes 40A, 40A... Penetrating in the plate thickness direction. The fixing member 40 is fixed to the lower portion 7 so that the through hole 40 </ b> A communicates with the groove portion 72.

  The through holes 40A are arranged in parallel along the longitudinal direction of the fixing member 40 at equal intervals, and are constituted by an insertion hole 40b and a fixing hole 40c.

  The insertion hole 40b has a circular shape in plan view, and is formed to communicate with one end of the fixed hole 40c. The insertion hole 40 b is formed with a larger diameter than the base portion 20 a of the positioning hook 20. Thereby, the base 20a can be inserted through the insertion hole 40b.

The fixing hole 40c has a rectangular shape in plan view. The width of the fixing hole 40c in the short direction is formed larger than the width of the protruding portion 20b in the horizontal direction. Thereby, the protrusion part 20b can be inserted in the fixing hole 40c (refer FIG.14 (c)).
The width in the short direction of the fixing hole 40c is smaller than the diameter of the base portion 20a of the positioning hook 20 (see FIG. 14C). Thus, when the protruding portion 20b of the positioning hook 20 is inserted into the fixing hole 40c, the upper surface 20d of the base portion 20a comes into contact (surface contact) with the lower surface 40d of the fixing member 40, and the positioning hook 20 is removed from the groove portion 72. It can be prevented from getting out.

  Next, a method for fixing the positioning hook 20 will be described with reference to FIG.

First, the base portion 20a of the positioning hook 20 is inserted into the groove portion 72 from the insertion hole 40b of the fixing member 40 (see FIG. 14A).
After the base portion 20a is inserted into the groove portion 72, the positioning hook 20 is slid toward the fixing hole 40c, and the protruding portion 20b is inserted into the fixing hole 40c. At this time, the protruding portion 20b is inserted until one end thereof contacts the inner wall surface of the fixing hole 40c (see FIG. 14B).
After the protrusion 20b is inserted into the fixing hole 40c, the reflecting member 4 is raised.
When the reflecting member 4 is raised, the positioning hook 20 is pulled upward, and a part of the upper surface 20d of the base portion 20a comes into contact (surface contact) with the lower surface 40d of the fixing member 40.
Thereby, the positioning hook 20 can be prevented from coming out of the groove portion 72 and the positioning hook 20 is fixed to the fixing member 40.

  When removing the positioning hook 20 from the fixing member 40, the reflecting member 4 is lowered, and the positioning hook 20 is slid toward the insertion hole 40b so that the protruding portion 20b is taken out from the fixing hole 40c. The hook 20 is lifted upward, and the base portion 20a is extracted from the groove portion 72 and the insertion hole 40b.

Next, the angle adjusting operation of the reflecting member 4 will be described.
In a state where the reflecting member 4 is pulled out and no external force is applied, the pulled-out reflecting member 4 stops in a state parallel to the window portion 9. Therefore, when the positioning hook 20 is engaged with a location closer to the indoor side of the fixing member 40, the angle θ formed by the reflecting member 4 and the window portion 9 increases, and the positioning hook 20 is moved closer to the outdoor side of the fixing member 40. When engaged with a place, the angle θ decreases.
That is, when the engagement position between the positioning hook 20 and the fixing member 40 is changed from the indoor side to the outdoor side, the angle θ formed by the reflecting member 4 and the window portion 9 becomes gradually smaller, and conversely the positioning hook. As the engagement position between 20 and the fixing member 40 is changed from the outdoor side to the indoor side, the angle θ formed by the reflecting member 4 and the window portion 9 increases gradually.
That is, by changing the position of the positioning hook 20 on the fixing member 40, the inclination of the reflecting member 4 can be freely changed.

According to the bay window lighting device according to the modified example described above, it is possible to obtain substantially the same effect as the bay window lighting device according to the present embodiment.
In addition, the positioning hook 20 can be fixed to the fixing member 40 simply by inserting the positioning hook 20 into the groove 72 from the insertion hole 40b of the fixing member 40 and sliding it into the fixing hole 40c. The engagement position between the hook 20 for fixing and the fixing member 40 can be easily changed, and as a result, the angle adjustment of the reflecting member 4 with respect to the window portion 9 can be easily performed.
