Description

  The present invention relates to a light control mechanism such as a louver that adjusts the amount of light entering a room or the like when light enters an opening such as a window of a building.

  Conventionally, sunlight can be obtained by entering sunlight through an opening such as a glass window provided in a building, but if a large amount of visible light or infrared light enters through the opening, the room brightness becomes excessive or room temperature is increased. May increase and worsen the indoor environment. For this reason, in order to appropriately control the amount of light incident on the room, it is generally used to attach a louver.

In FIG. 19A, a louver 100 has a structure in which a plurality of louver materials 101 made of a thin and thin light shielding plate material are arranged at a predetermined angle and interval. These louver materials 101 are usually manufactured in a certain shape using plastic, metal, earthenware, wood or the like. The louver 100 can roughly control the solar radiation by blocking a certain range of sunlight with respect to the incident angle of the sun.
In FIG. 19B, since the incident angle of sunlight changes according to time and season, an operation member such as a string, a motor, and the like are provided so that the installation angle of the louver material 101 of the louver 100 can be adjusted. Although it is known, it is difficult to finely adjust the incident light simply by adjusting the angle of the plate-like louver material 101, and it is often too bright or too dark.

  Moreover, what was described in patent document 1 is known as a louver which adjusts the amount of sunlight shading by changing the angle of a louver material. In this louver, the flat louver material has a flat surface on which sunlight is received, and a fine prism is formed on the back surface. Then, by changing the inclination angle of the louver material by the driving device, the light is reflected on the surface, or the light is incident and refracted by the prism to be taken into the room.

  As another louver 102, as shown in FIG. 20, a plurality of louver materials 103 made of a ceramic and hollow tube with a plurality of fine holes are arranged and water is passed through the louver material 103. Are known. In this louver 102, water in the tubular louver material 103 heated by sunlight is vaporized and discharged from the hole as vapor, thereby exhibiting a cooling effect that takes away the heat of the surrounding outside air.

JP 2000-182413 A

By the way, although the altitude and position of the sun change depending on the season, there is a drawback that a fixed shape louver cannot cope with all seasons. This point was the same even when the louver material was movable.
In particular, in FIG. 21, when there is a shield such as another building that partially blocks the sunlight in the vicinity of the opening of the building provided with the louver 100, the opening is shaded and shaded. There was a part. It is not necessary to adjust the louver 100 so as to block the sunlight in the shaded part of the opening, but since the louver 100 is also provided in that part, the incident of necessary light is hindered. There was a drawback that the temperature and the like could not be properly secured.
In this case, as shown in FIG. 22, even if the louver material 101 is movable, if the angle of the louver material 101 is set on the basis of the portion that is exposed to sunlight, the portion that is shaded will be exposed to sunlight to prevent the incidence of light. There was a problem that the temperature was lowered because it was too dark. Therefore, even with the louver 100 capable of adjusting the angle, it has been difficult to properly adjust the sunlight.

  In addition, when water is passed through the tubular louver material 103 of the louver 102 shown in FIG. 20, the environmental temperature in the vicinity of the louver material can be lowered by evaporation of water, but the angle of the louver material 103 cannot be adjusted. There is a drawback in that the brightness of the room cannot be adjusted because the shielding amount of incident light cannot be changed. In addition, there is a disadvantage that maintenance is troublesome because a hole for releasing the heat of vaporization is clogged or a tube is clogged.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a light control mechanism capable of collecting light by finely adjusting incident light.

The light control mechanism according to the present invention is a light control mechanism in which a plurality of shielding members are arranged to adjust the amount of light passing therethrough, wherein the shielding member is a plate or a tube extending in the longitudinal direction, In this position, the cross-sectional area or the width is changed so as to be smaller than that of other portions.
According to the light control mechanism of the present invention, when adjusting the lighting by arranging the light control mechanism before or after the opening of a building window or the like, the shielding member is cut off in an area where the amount of incident light is small, such as a shade. Place a portion with a small area and a large amount of light extraction, and place a portion with a large cross-sectional area or width of the shielding member and a small amount of light extraction in an area with a large amount of incident light such as the sun. And can adjust the temperature.
The shielding member may have a shape in which the central portion or at least one end portion in the longitudinal direction changes so that the cross-sectional area or width is smaller than the other portion.

Also, the shielding member has a plate-like shape at one end in the longitudinal direction and a polygonal shape at the other end, and changes so that the cross-sectional area or width is smaller than other portions at any position in the longitudinal direction. It may be a shape.
In this case, when adjusting the daylighting by arranging the light control mechanism before or after the opening of the building, for example, in the area where the incident light amount is small due to the shadow of the building etc. By arranging a large portion and arranging a portion having a large cross-sectional area or width of the shielding member and a small amount of collected light in an area where the amount of incident light is large, the amount of collected light can be finely adjusted.

The shielding member may be plate-shaped or cylindrical and twisted along the longitudinal direction thereof.
In the portion where the shielding member is twisted with respect to the light incident direction, the light shielding area is relatively small, and therefore the amount of light extraction is large. In addition, when a shielding member is cylindrical, the thing of appropriate shapes, such as cylindrical shape and polygonal cylinder shape, is employable.

Further, the shielding member may be formed in a plate shape and be able to be bent or wound in the longitudinal direction or the short direction.
Bending or winding the shielding member in the longitudinal direction increases the amount of light collected on the end side where the shielding member is folded or wound, for example, adjusting the amount of light collected on one end side or the other end side in the longitudinal direction of the shielding member it can. Further, by bending or winding the shielding member in the short direction, the width of the shielding member in the short direction is narrowed, and the amount of light collected between the adjacent shielding members is increased.

Further, the shielding member may be formed in a plate shape by arranging a plurality of shielding bands in parallel in the longitudinal direction or the lateral direction at a predetermined interval.
By forming a plurality of shielding bands as a shielding member in parallel in a longitudinal direction or a short direction in parallel with each other and forming a plate shape, light is allowed to pass through a gap between adjacent shielding bands, so that fine and soft lighting can be performed.

Moreover, the cooling member which supplies a cooling fluid to a shielding member is provided, and the shielding member may hold | maintain the cooling fluid supplied from a cooling device so that vaporization is possible.
Supplying the cooling liquid to the shielding member holds the cooling liquid, and when sunlight is irradiated to the shielding member, the heated cooling liquid evaporates, thereby removing the heat of vaporization and lowering the temperature of the surrounding environment. it can. It should be noted that cloth or paper having a high cooling liquid holding performance, mesh-like metal, synthetic resin, or the like can be used as the shielding member for holding the cooling liquid.

Further, the cooling means may be provided with a supply pipe for supplying the coolant to the shielding member.
The cooling liquid can be supplied to the shielding member through the supply pipe to be adsorbed.

The shielding member may be provided with a driving device that rotates or adjusts the angle of the shielding member.
The light intensity can be adjusted by rotating or adjusting the angle of any of the shielding members described above by the driving device. For example, since the light shielding area for incident light is changed by rotating or adjusting the angle of the shielding member, the light intensity can be increased or decreased. . The shielding member may be rotated by a predetermined angle by adjusting the inclination angle of the shielding member by rotating the driving device, or the area of the light shielding region may be increased or decreased by making a full rotation.

  A plurality of shielding members may be arranged extending in the horizontal direction, the vertical direction, or the oblique direction.

  According to the light control mechanism of the present invention, the shape of the shielding member is changed at any position in the longitudinal direction so that the cross-sectional area or the width is smaller than the other portions, so that the light of each shielding member can be reduced. Since the passing amount can be changed in the longitudinal direction, the brightness and temperature can be finely adjusted by changing the amount of incident light.

Hereinafter, light control mechanisms according to embodiments of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a louver 1 as a light control mechanism according to a first embodiment of the present invention.
The louver 1 is disposed outside a glass window of a building (not shown), for example, and adjusts sunlight and ventilation to be inserted into the glass window. The louver 1 in this embodiment is configured by arranging a plurality of long plate-like shielding members 2 extending in the left-right direction in the up-down direction. The shielding member 2 is a plate-like portion 3 having one end that forms a wide plate, and the other end is a prismatic portion 4 that has a polygonal cross section, for example, a triangular shape. The cross-sectional shape of the other end is not limited to a triangle, and can be formed into an appropriate polygonal shape such as a quadrangle or a pentagon.

  In addition, an opaque light-shielding member such as wood, metal, or synthetic resin is used as the shielding member 2, but instead of this, it may be made of a material that transmits light to some extent, such as rubbed glass or frosted glass. Good. When a material that transmits light to some extent is used, an intended amount of light can be collected in the room, and brightness and temperature can be adjusted as appropriate. About the material of the shielding member 2, the same thing can be used also in other embodiment etc. which are mentioned later.

The plate-like portion 3 changes so that the width and the cross-sectional area gradually become narrower from one end portion toward the prism portion 4, and the prism portion 4 gradually becomes a triangular shape from the other end portion toward the plate-like portion 3. The cross-sectional area and the width are changed so as to increase, and the plate-like portion 3 and the prismatic portion 4 are smoothly changed and connected at the central portion 5. Therefore, the shielding member 2 is formed so that the width and the cross-sectional area gradually become smaller gradually from the plate-like portion 3 that is one end portion toward the prism portion 4 that is the other end portion.
Then, one side of the plate-like portion 3 along the longitudinal direction is formed so as to coincide with the top side 2 a of the prismatic portion 4. Therefore, the height of the prismatic part 4 is the same as the thickness of the plate-like part 3, or is formed so as to gradually decrease from the central part 5 toward the other end part, and the gap between the shielding members 2 and 2 arranged vertically. The prism portion 4 is set larger than the plate portion 3.

Therefore, the shielding member 2 according to the first embodiment constitutes a three-dimensional shielding material, and one end portion of the plate-like portion 3 has the highest shielding ratio of sunlight incident obliquely from above, and the other end. The shading ratio gradually decreases toward the part. In addition, in the prism portion 4 from the central portion 5 in the longitudinal direction to the other end portion, the outer side of the top side 2a (the left side in FIG. 1) forms a slope 4a having a triangular cross section. Reflect sunlight. Therefore, the gaze of a person from a surrounding building or the like can be reflected and shielded by the inclined surface 4a of the prism portion 4.
Note that the angle of the louver 1 can be adjusted by an operating member such as a string (not shown) attached to each shielding member 2, and the lighting can be adjusted by inclining each shielding member 2 in the light incident direction. Further, a driving device 12 to be described later that rotates each shielding member 2 may be provided so that the angle can be adjusted or the rotation can be set.

  Since the louver 1 according to the present embodiment has the above-described configuration, for example, as shown in FIGS. 21 and 22, when a part of the louver 1 is attached to a glass window that becomes a shadow of another building, a shielding member is provided in a shaded part. 2 in the region from the central portion 5 to the prism 4 at the other end as appropriate, the appropriate length portion on the plate-like portion 3 side of the shielding member 2 is positioned in the portion that becomes the sun, The angle of the shielding member 2 is adjusted so that sunlight is blocked by an operating member such as a string.

Therefore, in the area of the prism portion 4 that is shaded by other buildings for a long time, the gap between the upper and lower prism portions 4 is large, and the ratio of sunlight that is incident on the glass window is small. High temperature can be maintained. In the region of the plate-like portion 3 that takes a long time to go in the sun, the ratio of sunlight that is incident on the glass window is large, and the room can be suppressed from becoming too bright and having a high temperature.
Therefore, by arranging the louver 1 according to this embodiment in front of the glass window, the amount of sunlight entering the room through the glass window can be balanced between the shaded part and the sunny part, and the brightness and temperature are finely adjusted. it can. Moreover, since the shielding member 2 is a three-dimensional shielding material, it can reflect sunlight and also shield the surrounding line of sight.

Next, a louver 7 as a light control mechanism according to a second embodiment of the present invention will be described with reference to FIG.
In the louver 7 according to the second embodiment, a plurality of shielding members 8 are arranged in the vertical direction, for example. The shielding member 8 is a plate-like portion 9 having one end with a wide quadrangular plate shape, and the other end is a prismatic portion 10 having a triangular cross section. The shielding member 8 has the smallest cross-sectional area of the central portion 11 in the longitudinal direction, for example, has a substantially circular cross section, and gradually increases in cross-sectional area and width from the central portion 11 toward the plate-like portion 9 that is one end. One end portion is changed to have a maximum cross-sectional area with a maximum width. Further, the triangular cross-sectional area and the width gradually increase from the central part 11 toward the other end of the prism 10, and the other end changes to a maximum cross-sectional triangle with the maximum width. . The plate-like portion 9 and the prismatic portion 10 have a circular cross section with a smoothly changing outer shape at the central portion 11.

  The louver 7 according to the second embodiment is also a three-dimensional shielding material, and the width and the cross-sectional area at the central portion 11 in the longitudinal direction of each shielding member 8 are the smallest and the gap between the upper and lower shielding members 8 is large. Between 8 and 8, the light shielding amount is the smallest and the incident light quantity of sunlight is the largest. On the other hand, since the width gradually increases from the central portion 11 toward the plate-like portions 9 and the prisms 10 at both ends, the light shielding amount of sunlight gradually increases and the amount of light collected decreases. In addition, since the prism portion 10 has a triangular cross section, most of the light incident on the outer one inclined surface 10a is reflected, and the light shielding amount is large. Also in the louver 7 according to the second embodiment, the above-described operation member such as a string or the driving device 12 may be provided.

Therefore, since the louver 7 according to the second embodiment has the above-described configuration, the angle of the shielding member 8 is adjusted so that sunlight is blocked by an operation member such as a string. Then, even if the center of the glass window facing the vicinity of the central portion 11 of the shielding member 8 is shaded, the amount of light can be maximized, and the amount of light collected in the region of the plate-like portion 9 and the prism portion 10 at both ends can be minimized. Can adjust brightness and temperature. Therefore, when the central portion of the louver 7 is shaded and both sides are sunny, the room can be finely adjusted to a suitable lighting and temperature. In particular, the shielding member 8 is a three-dimensional shielding material, which can reflect sunlight well and shield the surrounding line of sight by the inclined surface 10a facing the outside of the prismatic portion 10 and the plate-like portion 9.
Also in the second embodiment, if the shielding member 2 is made of a material that transmits light to some extent, such as rubbing glass or frosted glass, an intended amount of light can be incident into the room, and brightness and temperature can be adjusted. Fine adjustment.
In the louvers 1 and 7 according to the first and second embodiments described above, the portion where the cross-sectional area is smaller than the other portions is not limited to the central portion or the end portion in the longitudinal direction, It may be a portion, and any shape that changes so that the cross-sectional area or width is smaller than the other portions at any position in the longitudinal direction may be used. This also applies to other embodiments and modifications described below.

Next, a louver 13 as a light control mechanism according to a third embodiment of the present invention will be described with reference to FIG.
The louver 13 according to the third embodiment has a configuration in which a shielding member 14 extending in the vertical direction is disposed on the front surface of the glass window, and a plurality of shielding members 14 are arranged in the horizontal direction. Each shielding member 14 in the third embodiment has a rectangular plate-like or sheet-like shielding surface 16 attached to a central axis 15 extending in the vertical direction, and the shielding surface 16 has a central axis at its upper end and lower end. It is twisted so that the attachment angle to 15 is different.

Therefore, the material of the shielding surface 16 is formed of cloth, paper, flexible or deformable metal, synthetic resin, or the like. In particular, when cloth or paper is used as the shielding surface 16, it is preferable to attach cloth or paper to the upper end frame 15a and the lower end frame 15b of the central shaft 15. Such a shielding member 14 is referred to as a free deformation type shielding material.
In the shielding member 14, the upper end frame 15a and the lower end frame 15b may be relatively twisted by supporting the shielding surface 16 with only the upper end frame 15a and the lower end frame 15b without providing the central shaft 15.

  In the louver 13 according to the third embodiment, it is possible to ensure the balance of the amount of incident light by changing the angle of each of the plurality of shielding members 14 by 90 degrees, for example. For example, in the example of four shielding members 14 shown in FIG. 3, the left end and the third shielding member 14a from the left direction have a large incident light amount at the upper part and a large light shielding amount at the lower part. On the contrary, the second and right end shielding member 14b can obtain a characteristic that the light shielding amount at the upper part is large and the incident light amount at the lower part is large. The combination and arrangement of the twisted shielding members 14 can be arbitrarily selected. Moreover, the shielding member 14 has an area | region where a width | variety becomes narrow with respect to the incident direction of light, and an area | region which becomes wide, These can be adjusted so that it may form in the position in any one of a longitudinal direction.

According to the louver 13 according to the third embodiment, since the shielding member 14 is twisted in the longitudinal direction of the central shaft 15, the incident light quantity can be adjusted between the upper part, the central part, and the lower part. The louver 13 can be manufactured by determining the orientation of the glass window to which the plurality of light shielding members 14 should be attached and the positional relationship with the surrounding buildings.
Further, if a configuration in which a plurality of the same shielding members 14a are arranged as the louver 13 is adopted, the amount of light collected into the room through the glass window is large at the top and small at the bottom, and a configuration in which a plurality of shielding members 14b are arranged can be adopted. For example, the amount of light collected into the room through the glass window is small at the top and large at the bottom.

Moreover, as shown in FIG. 3, the structure connected with the drive device 12 provided with the motor which respectively rotates the center axis | shaft 15 of each shielding member 14 is employ | adopted, the drive device 12 is driven, and each shielding member 14 is interlocked | linked. Since the amount of incident light can be changed between each of the shielding members 14, the amount of incident light into the room can be periodically changed and adjusted.
Note that the rotation of the shielding member 14 by the driving device 12 may be performed only by adjusting the inclination angle of the shielding member 14 with respect to incident light by rotating it by a predetermined angle. You may let them.

Next, FIG. 4 shows a first modification of the louver 13 according to the third embodiment.
In FIG. 4, the shielding members 14a and 14b are not necessarily arranged at regular intervals, and may be arranged at irregular intervals. In the first modification shown in FIG. 4, the distances a, b, c between the adjacent shielding members 14a, 14b are set to different distances. Or you may set the space | interval of shielding member 14a, 14b at random.

  Further, in the louver 13 shown in FIGS. 3 and 4, the shielding members 14 are arranged in the same straight line, but they are not arranged in the same straight line as in the louver 13 according to the second modification shown in FIG. You may arrange in a zigzag shape. In this case, when sunlight does not enter from the front of the louver 13 and sunlight enters from an oblique direction so as to form an acute angle with the glass window, the shielding member 14 is arranged in a zigzag shape with respect to the glass window. You can adjust the amount of light.

Next, FIG. 6 shows a louver 13 according to a third modification.
The central axis 15 of each shielding member 14 is arranged vertically in the above-described third embodiment or modification, but may be arranged horizontally as in the first and second embodiments. Or you may arrange | position so that the center axis | shaft 15 of each shielding member 14 may straddle a diagonal direction, ie, a horizontal surface and a perpendicular surface, as shown in FIG.

Next, FIG. 7 shows a louver 13 according to a fourth modification.
In the above-described sunlight shielding member 14 shown in FIG. 7A, the central axis 15 is rotatably supported by the upper end receiving portion 17 and the lower end receiving portion 18, and the shielding surface 16 has an upper end frame 15a and a lower end frame 15b. It is supported by. And the light-shielding range of sunlight can be adjusted by twisting the lower end frame 15b relatively with respect to the upper end frame 15a.

Further, in the shielding member 19 shown in FIG. 7B, the central shaft 15 is formed in a short length that hangs down from the upper end receiving portion 17 to the middle portion in the vertical direction, and a screw 20 is provided at the lower portion of the central shaft 15, for example. The lower end portion is rotatably screwed and is supported by the lower end receiving portion 18 so as to be rotatable. The shielding surface 16 has an upper end frame 15 a fixed to the central shaft 15 and a lower end frame 15 b fixed to the screw 20.
Therefore, the shielding member 19 rotates the screw 20 to rotate the lower part of the shielding surface 16 and adjust the twisting condition of the shielding surface 16.

Further, in the shielding member 22 shown in FIG. 7C, the length of the shielding surface 16 is shortened to about ½ of the distance between the upper end receiving portion 17 and the lower end receiving portion 18, and the central axis 15 is the shielding surface. The screw 20 is rotatably engaged with the lower end portion of the central shaft 15, and the screw 20 extends below the shielding surface 16. The shielding surface 16 is attached to an upper end frame 15 a fixed to the central shaft 15 and a lower end frame 15 b provided on the screw 20.
Therefore, the shielding surface 16 is configured to be suspended from the upper end receiving portion 17 by the central shaft 15 and the screw 20, and the shielding member 22 is vertically suspended by the screw 20 serving as a weight. The upper half of the shielding member 22 is shielded by the shielding surface 16, but the lower half does not have the shielding surface 16 and has a configuration through which sunlight passes completely. In addition, the shielding surface 16 can be twisted by rotating the screw 20, thereby adjusting the light shielding area of sunlight by the shielding surface 16.

  As described above, the shielding members 14, 19, and 22 shown in FIGS. 7A, 7B, and 7C rotate the lower end frame 15b relative to the upper end frame 15a of the shielding surface 16 so as to block the sunlight. To adjust the lighting and temperature.

Next, a fourth embodiment of the present invention will be described with reference to FIG.
The light control mechanism 24 according to the fourth embodiment is configured by arranging a plurality of shielding members 25 extending in the vertical direction in the horizontal direction at predetermined intervals. Each shielding member 25 is provided with a shielding surface 26 of a cylindrical free deformation type shielding material between, for example, a circular upper end frame 25a and a lower end frame 25b, and the free deformation type shielding material is, for example, cloth, paper, or flexible It is made of metal or synthetic resin. Then, by twisting the lower end frame 25b relative to the upper end frame 25a, the cylindrical shielding surface 26 can be formed in a pair of conical shapes facing each other, and the width is arbitrary at any position in the longitudinal direction. It is formed by twisting so as to be narrow, and the shielding ratio of sunlight is adjusted. In the example shown in FIG. 8, the adjacent shielding members 25 are arranged in directions different by 180 degrees, but may be attached in the same angle direction. Moreover, it can also set to the position rotated to arbitrary angles about each shielding member 25. FIG.

  In the light control mechanism 24 according to the fourth embodiment, the light shielding property of sunlight is reduced by twisting the cylindrical shielding surface 26 of each shielding member 25 small, and the light shielding property is set large by twisting strongly. Moreover, the light control mechanism 24 has the largest amount of light collected at the central portion in the longitudinal direction of the shielding member 25, and the amount of light collected gradually decreases toward the upper and lower ends.
