  However, the light shelf as described in Patent Document 1 is a product that is considered in the design stage of a building because of its structure, and there is a problem that it is not easy to attach later according to the demands of residents.

  In addition, since the light shelf is fixedly installed, for example, even if it is desired to take direct solar radiation indoors in order to increase the heating efficiency in winter, the light shelf is installed outside the room. Therefore, the solar radiation energy that can be taken into the room is reduced. Moreover, since the light shelf is fixed horizontally, there is also a problem that the amount of reflected sunlight reflected on the ceiling surface cannot be adjusted according to the solar altitude. As described above, the fixed light shelf has a problem that the degree of freedom of use of daylight is low.

  SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and has an object to provide a daylight use blind that allows daylight to be taken indoors and can be used as lighting, and has a higher degree of freedom in daylight use. To do.

In order to achieve the above-described object, the present invention provides an upper fixed support member fixed to a fixed surface such as a window frame, an upper movable support member, an upper end supported by the upper movable support member, and reflects daylight. A shielding member capable of forming a possible shielding surface, a pair of side movable support members whose upper ends are connected to the upper movable support member, and a lower end of the pair of side movable support members are rotatably supported. A lower support member, and the upper fixed support member and the upper movable support member are connected by an opening / closing member so that the relative positional relationship between each other can be changed, and by operating the opening / closing member, The side movable support member is tilted with its lower end as a fulcrum, and the tilt angle of the shielding surface of the shielding material is changed, whereby the angle of daylight reflected by the shielding surface is made variable.

Further , the upper fixed support member is provided with an operation unit capable of operating the opening / closing member.

Further , when the upper movable support member approaches the upper fixed support member, the shielding material is held at a substantially vertical angle, and when the upper movable support member is separated from the upper fixed support member, the shielding material is held at a substantially horizontal angle. It is comprised as follows.

Furthermore , the upper movable support member is provided with a drive mechanism capable of opening and closing the shielding material.

Further , a second shielding material capable of forming a shielding surface capable of reflecting daylight is provided below the lower support member, and the shielding surface is formed by combining the shielding surface of the shielding material and the shielding surface of the second shielding material. Can be formed.

Further , the shielding material is a plurality of rotatable slats, and the angle of the slats can be adjusted.

  According to the present invention, since it can be installed by fixing the upper fixed support member to a fixed surface such as a window frame in the same manner as a general blind, it can be retrofitted even after the completion of construction work. . In addition, since the shielding material can be tilted, the daylight can be reflected on the shielding surface of the shielding material and irradiated to the ceiling surface of the room, and the existing light shelf that contributes to energy saving by using daylight can be used. The same effect can be obtained.

  Further, when daylight use is unnecessary, the degree of freedom of daylight use can be increased by holding the shielding material at a vertical angle. For example, if the shielding material is opened, the solar radiation can be actively taken in, and if the shielding material is closed, the solar radiation can be completely shielded.

  Furthermore, since the relative position of the upper movable support member with respect to the upper fixed support member can be adjusted by operating the operation unit, the tilt angle of the shielding material can be adjusted, and reflection of daylight into the room by the shielding surface according to the solar altitude. The amount can be adjusted.

  In addition, since the shielding material can be opened and closed by operating the drive mechanism, the amount of reflection of daylight can be further adjusted, the tilt angle of the shielding material can be adjusted, and the slat as the shielding material can be further adjusted. By adjusting the angle, it is possible to adjust the optimal solar shading and daylight introduction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a daylight utilization blind according to an embodiment of the present invention.

  The daylight utilization blind 10 is generally arranged in a fixed support frame 16 fixed to a fixed surface 12 such as a window frame, a movable support frame 22 arranged in the fixed support frame 16, and a movable support frame 22. It has the 1st shielding material 18 and the 2nd shielding material 20 arrange | positioned under the fixed support frame 16. As shown in FIG.

  The fixed support frame 16 extends vertically between the upper fixed support member 16a corresponding to the upper frame, the lower fixed support member 16b corresponding to the lower frame, and the upper fixed support member 16a and the lower fixed support member 16b. A pair of side fixed support members 16c, 16c. The fixed support frame 16 is fixed by attaching the upper fixed support member 16 a to the fixed surface 12 by the bracket 14. However, the upper fixed support member 16a and the lower fixed support member 16b can be individually fixed to the fixed surface as separate members instead of being integrally formed as a fixed support frame.

  The movable support frame 22 extends vertically between the upper movable support member 22a corresponding to the upper frame, the lower movable support member 22b corresponding to the lower frame, and the upper movable support member 22a and the lower movable support member 22b. A pair of side movable support members 22c, 22c.

  The lower movable support member 22b is connected to the lower fixed support member 16b of the fixed support frame 16 by a hinge 17, so that the movable support frame 22 can tilt with the hinge portion of the fixed support frame 16 as a fulcrum. It has become. Here, the lower movable support member 22b may be omitted, and the lower end of the side movable support member 22c may be directly connected to the lower fixed support member 16b.

  The first shielding member 18 includes a multi-stage slat 36 that is rotatably aligned and supported by a ladder cord 34 suspended from the upper movable support member 22a. The multi-stage slats 36 constitute a shielding surface 36a capable of reflecting daylight.

  A bottom rail 40 is disposed below the lowermost slat 36, and the lower end of the ladder cord 34 is connected to the bottom rail 40. When the bottom rail 40 is lowered to the lowest position, the lower end portion is inserted into the lower movable support member 22b.

  The bottom rail 40 is also connected to the lower end of a lifting / lowering cord 38, and the lifting / lowering cord 38 passes through a plurality of slats 36.

  A first shielding material drive mechanism 50 for opening and closing the first shielding material 18 is provided in the movable support frame 22. In this example, the opening and closing of the first shielding member 18 includes rotation and elevation of the slat 36. The first shielding member drive mechanism 50 is disposed over the entire length in the longitudinal direction inside the upper movable support member 22a, which is rotated by the operation rod 52 and the operation rod 52 hanging from the right end in FIG. 1 of the upper movable support member 22a. A rotating shaft 54, a stopper 53 disposed in the upper movable support member 22 a, and a plurality of drive drums 55 that are disposed apart from each other in the longitudinal direction in the upper possible support member 22 a and through which the rotation shaft 54 can rotate integrally. And having.

  The upper end of the ladder cord 34 is connected to the drive drum 55 so as to be wound and unwound. The slat 36 can be rotated by rotating the operating rod 52 to rotationally drive the rotating shaft 54 and rotating the driving drum 55 to tilt the ladder cord 34.

  After being inserted into the upper movable support member 22 a, the elevating cord 38 is routed along the longitudinal direction of the upper movable support member 22 a, and hangs down within the operation rod 52 via the stopper 53 to lower the lower end of the operation rod 52. And is connected to the operation unit 56. The slat 36 can be raised and lowered by raising and lowering the operating portion 56 and raising and lowering the bottom rail 40 via the raising and lowering cord 38.

  A guide wire 42 is stretched between the upper movable support member 22a and the lower movable support member 22b by inserting a multi-stage slat 36, and the upper end of the guide wire 42 is in the upper movable support member 22a. The lower surface of the guide wire 42 is fixed to the lower surface of the lower movable support member 22b by the fixing member 60. Since the guide wire 42 restricts the movement of the first shielding member 18 in the front-rear direction, the alignment of the slats 36 can be maintained even when the movable support frame 22 is tilted.

  The first blind member 18 and the first shield driving mechanism 50 constitute a first blind element. The first shielding member driving mechanism 50 is mainly provided on the movable support frame 22, but is not limited to this, and a head box member different from the movable support frame 22 is attached to the movable support frame 22. It is also possible to arrange the first shielding material driving mechanism 50 inside.

  The second shielding member 20 is constituted by a multi-stage slat 66 that is rotatably aligned and supported by a ladder cord 64 suspended from the lower fixed support member 16b. The multi-stage slats 66 constitute a shielding surface 66a capable of reflecting daylight.

  A bottom rail 68 is disposed below the lowermost slat 66, and the lower end of the ladder cord 64 is connected to the bottom rail 68. The bottom rail 68 is also connected to the lower end of a lifting / lowering cord 62, and the lifting / lowering cord 62 is inserted with a plurality of slats 66.

  The lower fixed support member 16 b of the fixed support frame 16 is provided with a second shielding material driving mechanism 70 for opening and closing the second shielding material 20.

  Since the configuration of the second shielding material driving mechanism 70 is the same as the configuration of the first shielding material driving mechanism 50, detailed description thereof is omitted, but the slat 66 is seen from the right end portion of the lower fixed support member 16b in FIG. An operating rod 72 for rotating the operating rod 72 hangs down, and the lifting / lowering cord 62 passes through the operating rod 72, is led out from the lower end of the operating rod 72, and is connected to the operating portion 74. By rotating the operating rod 72 and tilting the ladder cord 64, the slat 66 can be rotated, and by raising and lowering the operating portion 74 and raising and lowering the bottom rail 68 via the raising and lowering cord 62. The slat 66 can be moved up and down.

  A second blind element is configured by the second shielding material 20 and the second shielding material driving mechanism 70 described above. The second shielding material driving mechanism 70 is mainly provided on the lower fixed support member 16b of the fixed frame 16, but is not limited thereto, and a head box member different from the lower fixed support member 16b is attached to the fixed frame 16. It is also possible to arrange the second shielding material driving mechanism 70 in the head box member attached to the lower part.

  The second blind element is different from the first blind element, and the guide wire 42 and the fixing members 58 and 60 are not provided.

  An operation cord 80 hangs down from the right end portion of the upper fixed support member 16a of the fixed support frame 16 in FIG. 1, and the operation cord 80 can rotate an operation portion 82 disposed in the upper fixed support member 16a. It has become. A plurality of operation portions 82 are disposed in the longitudinal direction of the upper fixed support member 16a in the longitudinal direction and a plurality of operation portions 82 are spaced apart in the longitudinal direction in the upper fixed support member 16a so that the rotational shaft 84 can rotate integrally. A rotating drum 86 that penetrates and a one-way clutch (not shown) that restricts the rotating shaft 84 to rotate only by an operation by the operation cord 80 are provided. One end of a cord-shaped opening / closing member 88 is connected to the rotating drum 86 so as to be wound and unwound.

  The other end of the opening / closing member 88 is led out from the upper fixed support member 16 a and connected to the upper movable support member 22 a of the movable support frame 22. Thus, the upper movable support member 22a is connected to the upper fixed support member 16a by the opening / closing member 88 so that the relative positional relationship can be changed.

  The first shielding member 18 is held at a substantially vertical angle when the upper movable support member 22a approaches the upper fixed support member 16a, and a substantially horizontal angle when the upper movable support member 22a is farthest from the upper fixed support member 16a. Held in.

  Next, the operation of the daylight utilization blind 10 will be described.

  When daylight does not need to be actively used as illumination, the daylight use blind 10 can be operated as a normal blind. In this case, the upper movable support member 22a is closest to the upper fixed support member 16a, and the first shielding member 18 is held vertically (FIG. 8A).

  In this state, as shown in FIG. 1 and FIG. 6A, when both the first shielding member 18 and the second shielding member 20 are in the state in which the slats 36 and 66 are rotated vertically, the daylight 94 that has passed through the window 92 is obtained. Intrusion into the room 96 is blocked by the slats 36 and 66, and the cooling load in summertime or the like can be reduced (see FIG. 8A).

  Further, by rotating the operating rod 52 from the state of the blind 10 shown in FIG. 1 and rotating the slat 36, it is possible to make the lighting possible from only the first shielding member 18 on the upper side. As shown in FIGS. 2 and 6 (b), when the slat 36 is rotated horizontally or tilted slightly toward the interior 96, the slat 36 as the first shielding member 18 is lowered. It will be in the state which can be daylighted in the state.

  On the other hand, when the operating rod 72 is rotated from the state of the blind 10 shown in FIG. 1 and the slat 66 is rotated, the lighting can be performed only from the second shielding member 20 at the lower part. Then, as shown in FIG. 6 (c), when the slat 66 is rotated until the slat 66 becomes horizontal or the slat 36 is inclined slightly toward the room 96, the slat 66 as the second shielding member 20 is lowered. It will be in the state which can be daylighted in the state which exists. In addition, by appropriately adjusting the angle of the slats 66 according to the solar altitude, it is possible to prevent unpleasant glare while shielding the direct sunlight while enabling the daylighting from the second shielding material 20.

  Further, as shown in FIG. 3, when both the slat 36 of the first shielding member 18 and the slat 66 of the second shielding member 20 become horizontal, or when the slat 36 is rotated so as to be inclined slightly toward the indoor 96 side. The slats 36 and 66 of the first and second shielding members 18 and 20 are in a state where they can be daylighted. As a result, the daylight 94 that has passed through the window 92 passes between the slats 36 and 66 and enters the room 96 so that the entire blind can be lit (FIG. 8C). Therefore, since a large amount of direct solar radiation can be taken into the room, solar radiation energy can be utilized to the maximum, and it can be used to increase heating efficiency in winter and the like. Further, by appropriately adjusting the angles of the slats 36 of the first shielding material 18 and the slats 66 of the second shielding material 20 in accordance with the solar altitude, it is possible to collect light from the entire blind, and it is uncomfortable while shielding direct sunlight. It is also possible to prevent glare.

  Moreover, the operation part 56 is pulled down from the state of the blind 10 shown in FIG. 1, and as shown in FIG.4 and FIG.6 (d), the slat 36 can be raised and the 1st shielding material 18 can be raised completely. Alternatively, when the lifting operation of the lifting / lowering cord 38 is stopped when the bottom rail 40 is at an arbitrary height, the stopper 53 restrains the movement of the lifting / lowering cord 38 and can stop the slat 36 at an arbitrary height. .

  On the other hand, as shown in FIG. 6E, the operating portion 74 is pulled down from the state of the blind 10 shown in FIG. 1, and the slat 66 is raised as shown in FIG. Can be raised. Alternatively, when the lifting operation of the lifting / lowering cord 62 is stopped when the bottom rail 68 is at an arbitrary height, a stopper (not shown) restrains the movement of the lifting / lowering cord 62 and stops the slat 66 at an arbitrary height. it can.

  Or as shown in FIG.6 (f), the window 92 can also be completely opened by raising both the slat 36 of the 1st shielding material 18, and the slat 66 of the 2nd shielding material 20 completely. Therefore, since a large amount of direct solar radiation can be taken into the room, solar radiation energy can be utilized to the maximum, and it can be used to increase heating efficiency in winter and the like.

  Next, when it is desired to actively use the sun as illumination, the rotary shaft 84 is rotated by operating the operation cord 80 and operating the operation unit 82 to open and close the rotary drum 86 that rotates integrally therewith. The member 88 is rotated in the unwinding direction. As a result, as shown in FIG. 7A, the distance between the upper fixed support member 16a and the upper movable support member 22a is increased by the length of the unrolled opening and closing member 88, and the hinge 17 is used as a fulcrum. The movable support frame 22 and the first shielding member 18 can be tilted toward the indoor 96 side.

  If the unwinding operation of the opening / closing member 88 is continued, the first shielding member 18 can be tilted until it reaches a horizontal angle as shown in FIGS.

  By appropriately adjusting the operation amount of the operation cord 80, the first shielding material 18 can be held at an arbitrary tilt angle between the vertical state and the horizontal state of the first shielding material 18.

  In this way, when the first shielding member 18 is tilted, the daylight 94 that has passed through the window 92 is reflected on the shielding surface 36a of the first shielding member 18 in the upper part as shown in FIG. 8B. Then, the ceiling surface 98 is irradiated, and the lower portion is blocked from entering the room 96 by the shielding surface 66 a of the second shielding material 20.

  The daylight 94 applied to the ceiling surface 98 can be used as indirect illumination in the room 96 by being further reflected by the ceiling surface 98. In this way, it is possible to contribute to reducing the power load of the room lighting.

  By operating the operation code 80, the angle of inclination of the first shielding member 18 and the movable support frame 22 is set to another angle instead of the horizontal, thereby changing the reflection angle of the daylight 94 on the shielding surface 36a, and thereby taking the light. The amount can also be adjusted. Particularly when the solar altitude is low, daylight can be efficiently reflected by setting the tilt angle of the first shielding member 18 and the movable support frame 22 to an angle rising from the horizontal. Further, by rotating the slat 36 of the tilted first shielding member 18, the reflection angle of the daylight 94 is changed and the daylight 94 entering between the slats 36 is adjusted, thereby adjusting the amount of light collected into the room 96. You can also

  Optionally, if the sun's altitude drops and direct sunlight enters the room through the gap formed between the slats 36, the tilt angles of the first shielding member 18 and the movable support frame 22 are adjusted. Further, it is possible to prevent the incidence of direct sunlight by rotating the slat 36. In addition to the state of the first shielding material 18, the amount of light collected into the room 96 can be further adjusted by changing the inclination angle of the slat 66 of the second shielding material 20. Furthermore, by adjusting the angle of the slats 36 of the first shielding material 18 and / or the slats 66 of the second shielding material 20 according to the solar altitude, the amount of light collected into the room 96 can be adjusted, and direct sunlight can be adjusted. It is also possible to prevent unpleasant glare while shielding.

  In this way, by changing the tilt angles of the first shielding member 18 and the movable support frame 22 according to the solar altitude, or by adjusting the angle of the slats 36 of the first shielding member 18, optimal solar radiation shielding and daylighting are achieved. Introductory adjustments can be made.

  The daylight utilization blind 10 described above can be retrofitted to a desired window where daylight is desired by being attached to the fixed surface of the window frame 12. Further, when it is desired to adjust the amount of light collected into the room 96 without using the daylight as illumination, the first shielding member 18 is held vertically to be used as a normal blind. Can increase the degree of freedom of daylight use. Furthermore, when the 2nd shielding material 20 is provided in the lower part, it is possible to light variously by combining the various states of various shielding materials 18 and 20 as mentioned above. In addition, the above state is an example, and it is of course possible to make a combination of other states.

  Furthermore, in the above embodiment, all operations are performed manually. However, the present invention is not limited to this, and at least a part of the operations may be performed electrically. An electric actuator for rotating 84 may be provided. The electric actuator can be controlled by a signal from a computer system or manually.

  Further, in the above embodiment, the shielding material is composed of a multi-stage slat. However, the present invention is not limited to this, and an arbitrary screen, for example, a screen on which flat or regular or irregular wrinkles are formed. It is also possible to configure.

  In the above embodiment, the daylight-use blind has the first shielding material and the second shielding material. However, the present invention is not limited to this, and it is also possible to have only the first shielding material. It is.

  Furthermore, in the above embodiment, the lower fixed support member 16b as the lower support member that supports the first shielding member is fixed, but the present invention is not limited to this, and the height of the lower support member itself can be adjusted. It can also be. In this case, the lower support member may be provided at a height suitable for reflection according to the altitude of the sun. Further, it is preferable that the shielding member 18 is configured to be expandable and contractable in accordance with the movement of the lower support member.
