[First Embodiment]
Hereinafter, the first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a top perspective view showing a room 100 to which the slat angle fixture 300 described later according to one aspect of the present invention is applied. As shown in FIG. 1, a panel 102 on which a lighting plate 101 is installed is provided on the side of the room 100, and the ceiling 100B at the upper part inside the room 100 is provided in the longitudinal direction and the short side as in rows S1 to S5. The indoor lighting devices 103 are provided side by side at intervals P in the direction. The panel 102 and the lighting plate 101 are fixed by fixing tools such as bolts and nuts that can be released from the fixing.

The panel 102 is, for example, a translucent plate-shaped glass or resin used for windows of buildings and vehicles. A light-reflecting ceiling material 100A is provided in the region E in the ceiling 100B within a predetermined distance from the panel 102.

As shown in the schematic cross-sectional view of FIG. 2, the panel 102 is provided with, for example, a solar radiation adjusting device 400 in addition to the lighting plate 101. In the solar radiation adjusting device 400, the angles of the slats 401 and 402 are adjusted by the ladder code 403 as described later. Specifically, for example, the solar radiation adjusting device 400 corresponds to a general blind or the like.

The slat angle fixing device 300 is provided in the solar radiation adjusting device 400 at substantially the same position as the lower end of the lighting plate 101, and the angles of the slat 401 and the slat 402 of the solar radiation adjusting device 400 are different with the slat angle fixing device 300 as a boundary. It has become like. Further, for example, a desk 104 is installed in the room 100, and the illuminance of the desk upper surface 104A, which is the upper surface of the desk 104, is measured when measuring the illuminance described later.

The light-reflecting ceiling material 100A preferably has a diffuse reflection property that brightens the inside of the room 100 (for example, the desk surface 104A) and a specular reflection property that suppresses the generation of glare light in the room 100. The light-reflecting ceiling material 100A may be a material obtained by embossing a metal plate having specular reflectivity, such as aluminum, with irregularities of about several tens of μm so as to have diffuse reflectivity.

The light-reflecting ceiling material 100A is a material in which a metal thin film such as aluminum having mirror-reflecting property is vapor-deposited on the surface of a resin plate that has been embossed with irregularities of about several tens of μm so as to have diffuse reflection. May be good.

The unevenness due to the embossing is preferably about several tens of μm, but the embossing may be formed on a curved surface having a period larger than several tens of μm. By appropriately changing the shape of the embossing, the light distribution characteristics and the light distribution characteristics of the light can be changed.

For example, the shape of the embossing applied to the light-reflecting ceiling material 100A is a stripe shape that goes toward the inside of the room 100 (hereinafter, this may be referred to as indoor or indoor) (in the lateral direction in FIG. 1). The light that guides the light to the back of the room and is reflected by the light-reflecting ceiling material 100A is diffused in the longitudinal direction in FIG. For example, when the size and orientation of the panel 102 are limited, it is effective to change the shape of the embossing applied to the light-reflective ceiling material 100A. The outside of the room 100 may be referred to as the outdoors.

In this way, the light-reflecting ceiling material 100A can reflect the light that has passed through the panel 102 and the daylighting plate 101, and guide the light to a place away from the panel 102 inside the room 100.

As shown in the schematic cross-sectional view of FIG. 2, the indoor lighting device 103 is a device that illuminates the inside of the room 100, and includes an indoor lighting device 103A, an illuminance detection unit 103B, and a control unit 103C. A plurality of indoor lighting fixtures 103A may be provided for each indoor lighting device 103, for example, a light emitting diode.

The illuminance detection unit 103B is, for example, an illuminance sensor that detects the illuminance which is the brightness of the indoor lighting fixture 103A, and is provided in a number corresponding to the indoor lighting fixture 103A. The illuminance detection unit 103B receives the reflected light from the irradiated surface irradiated by the indoor lighting fixture 103A and detects the illuminance of the irradiated surface (for example, the desk surface 104A).

One control unit 103C is provided for each indoor lighting device 103, and adjacent control units 103C are connected to each other in order to share a value such as a _{target illuminance L 0 of a target desk surface 104A.} The target illuminance L ₀ is, for example, the recommended maintenance illuminance 7501x in the office of "JIS Z9110 General Lighting Regulations". When calculating the illuminance, for example, the illuminance for each region of the desk top surface 104A is averaged.

The control unit 103C acquires the illuminance detected by the illuminance detection unit 103B, and performs feedback control for adjusting the illuminance of the corresponding indoor lighting fixture 103A based on the acquired illuminance. By performing feedback control by the control unit 103C, it is possible to acquire the illuminance due to light such as natural light that has passed through the panel 102 and the lighting plate 101 inside the room 100, and the illuminance in each region inside the room 100 is predetermined. Can be a value. It is assumed that the angles of the slats 401 and 402 may be adjusted in conjunction with the control by the control unit 103C.

The examples shown in FIGS. 1 and 2 are examples when the slat angle fixture 300 is used. For example, the slat angle fixture 300 is attached to the solar radiation adjusting device 400 without using the indoor lighting device 103 and the lighting plate 101. Of course, it is good to just install. Further, in FIGS. 1 and 2, an example in which the daylighting plate 101 is installed in the room 100 is given, but the present invention is not limited to this, and instead of the daylighting plate 101, a window-attached daylighting film, a daylighting glass, a daylighting louver, etc. Daylighter may be installed in room 100.

The daylighter refers to a device installed on the upper part of the panel 102 that emits light such as sunlight entering from the panel 102 in a predetermined direction and enables the light to be efficiently taken into the room. .. A device provided with a daylighter and slat angle fixtures 300, 500, 600, 700 described later may be referred to as a daylighting device. Further, a system including a daylighting device and a solar radiation adjusting device 400 may be called a daylighting system, and the daylighting system may further include an indoor lighting device.

FIG. 3 shows a schematic view showing the configuration of the slat angle fixture 300 according to the present embodiment. Further, FIG. 4 shows a schematic cross-sectional view of IV-IV of FIG. The slat angle fixture 300 includes a ladder cord insertion hole 302 into which a part of the ladder cord 403 at a predetermined position such as the lower end of the lighting plate 101 is inserted, and a ladder cord insertion hole having a length such as a _{slat interval L S.} A ladder code holding unit 305 for holding the ladder code 403 protruding from 302 is provided.

The material of the slat angle fixture 300 may be, for example, a metal such as aluminum or stainless steel, a resin such as polycarbonate, polyvinyl chloride, or polymethyl methacrylate resin, or a rubber-based or silicon-based material. ..

The solar radiation adjusting device 400 includes a plurality of slats 401, 402, a ladder code 403 that supports the plurality of slats 401, 402 and adjusts the angles of the plurality of slats 401, 402, and a hanging portion 404 that suspends the ladder code 403. Have. Each of the slats 401 and 402 is supported by being placed on a support cord 405 stretched between the ladder cord 403A on the outdoor side and the ladder cord 403B on the indoor side, for example.

The ladder code 403 supports, for example, all the slats 401 and 402 included in the solar radiation adjusting device 400. By pulling the ladder code 403A on the outdoor side upward, all the slat 401 and 402 are tilted so that the side on the outdoor side of the slat 401 and 402 rises upward. By pulling the ladder code 403B on the indoor side upward, all the slat 401 and 402 can be tilted so that the side on the indoor side of the slat 401 and 402 rises upward.

Further, normally, the ladder codes 403 (403A, 403B), 413 (413A, 413B), 423 (423A, 423B) are slats 401 (401A, 401B) on the indoor side and the outdoor side, respectively, as shown in FIG. 7 described later. , 401C), 402 (402A, 402B). Therefore, when attaching the slat angle fixture 300, the slat angle fixture 300 is attached to the ladder cords 403, 413, and 423 at positions aligned in the horizontal direction, respectively.

The slats 401 (401A, 401B, 401C) and 402 (402A, 402B) are supported by support cords 405 (405A, 405B, 405C, 405D, 405E), respectively. Further, although not shown, it is assumed that the ladder code 413 is provided with the support code 415 and the ladder code 423 is provided with the support code 425 as the ladder code 403 is provided with the support code 405.

Further, for example, the hanging portion 404 suspends the slats 401 and 402 from above by ladder cords 403, 413 and 423, and the slats 401 and 402 may be stored when they are not needed.

The slat angle fixture 300 fixes the relative angle between the angle of the slat 401 above the position where the slat angle fixture 300 is attached and the angle of the slat 402 below the position where the slat angle fixture 300 is attached. Therefore, the solar radiation adjusting device 400 can be roughly divided into the following four states, for example, with the slat angle fixture 300 attached.

That is, the slat 401 and 402 are fully open, the upper slat 401 is half open and the lower slat 402 is fully closed, and the upper half open and lower slat 401 and 402 are half open. It is in a half-open state and in a fully closed state in which the slat 401 and 402 are fully closed.

In the fully open state, the half open state, and the fully closed state, there is a slight difference in the angle between the slat 401 and the slat 402 at the position where the slat angle fixture 300 is attached. Further, since the relative angle between the slat 401 and the slat 402 is determined by the length of the ladder cords 403, 413 and 423 held by the ladder cord holding portion 305, the actual size such as the thickness, width and length of the slat angle fixture 300 is large. Depends on.

The solar radiation adjusting device 400 to which the slat angle fixture 300 is attached preferentially passes the light entering from the panel 102 in the fully open state, and passes a part of the light entering from the panel 102 in the half-open state, and is in a fully closed state. Then, it is assumed that most of the light entering from the panel 102 is blocked. Further, in the solar radiation adjusting device 400, when the upper half is half open and the lower part is fully closed, only a part of the light is passed through only the portion of the slat 401 of the solar radiation adjusting device 400 (hereinafter, this may be referred to as the upper part), and the slat 402 of the solar radiation adjusting device 400 is used. (Hereinafter, this may be referred to as the lower part) blocks most of the light.

Specifically, for example, the angle of the slats 401 and 402 when the slats 401 and 402 are parallel to the horizontal direction is set to 0 °. Further, for example, assuming that the angle of tilting upward in the vertical direction inside the room 100 is a positive angle, the fully open state means a range in which the angles of the slats 401 and 402 are 0 ° or more and 30 ° or less.

Further, for example, the half-open state refers to a state in which most of the vertically upward light that can brighten the entire room is blocked and the vertical downward light passes through, and more specifically, the slats 401 and 402. Refers to the range in which the angle of is -60 ° or more and 0 ° or less or 30 ° or more and 60 ° or less. Further, for example, the fully open state means a range in which the angles of the slats 401 and 402 are -60 ° or less or 60 ° or more.

By holding and shortening the ladder code 403, 413, 423 by the ladder code holding portion 305, the relative angle between the slat 401 and the slat 402 can be fixed above and below the place where the slat angle fixture 300 is attached.

Therefore, if the daylighting plate 101 is installed above the portion where the slat angle fixture 300 is attached, the upper part of the solar radiation adjusting device 400 allows light to pass appropriately even in the above four states, and the lower part of the solar radiation adjusting device 400. Then, the light can be blocked appropriately. The slat 402 is closed more than the slat 401 in order to fix the relative angle by shortening the ladder codes 403, 413 and 423.

When the slat angle fixture 300 is attached to the solar radiation adjusting device 400, it is attached not to the ladder cords 403A, 413A, 423A outside the room 100 but to the ladder cords 403B, 413B, 423B on the indoor side.

The operator pinches and bundles the ladder codes 403B, 413B, and 423B at the switching positions determined at the lower end of the lighting plate 101, and makes a ring made of the ladder codes 403B, 413B, 423B (hereinafter, this is simply called a ring). It may be) is passed through the ladder cord insertion hole 302 from the ladder cord storage portion 303 side described later.

Next, the operator spreads the ring protruding from the ladder cord insertion hole 302 and turns it toward the ladder cord storage portion 303, which is the back side of the protruding side, and causes the ladder cord holding portion 305 to hold the ladder cords 403B, 413B, and 423B. Ladder cord 403B that ladder cord holding section 305 holds, 413B, the length of 423B is desirably less slat spacing L _S.

This ladder cord 403B that ladder cord holding section 305 holds, 413B, the length of 423B is longer than the slat spacing L _S, slats 402A, 401C is for no longer fit in the solar adjustment device 400. This is because the support cords 405C and 405D that support the slats 401C and 402A are involved.

Incidentally ladder cord 403B that ladder cord holding section 305 holds, 413B, if the length of 423B is slat spacing L _S, the difference in relative angle between the slat 401 and the slats 402 is maximized.

The ladder code holding unit 305 includes a ladder code storage unit 303 for storing the ladder codes 403B, 413B, and 423B. Further, the ladder code holding portion 305 includes hooking portions 301 (301A, 301B) for hooking the ladder codes 403B, 413B, 423B and fixing the ladder codes 403B, 413B, 423B.

Further, the ladder code holding portion 305 has a sliding portion 304 (304A, 304B, 304C, 304D, 304E, 304F, 304G, 304H,) that slides the ladder cords 403B, 413B, 423B when accommodating the ladder cords 403B, 413B, 423B. 304I, 304J) and.

The operator uses, for example, sliding portions 304A, 304B, 304C, 304G, 304I when turning the ring protruding from the ladder cord insertion hole 302 toward the ladder cord storage portion 303 side, which is the back side of the protruding side. The operator first applies the ring to the sliding portion 304B having no corners, and then applies the same force toward the sliding portions 304A and 304C to spread the ring and spreads the ring to the ladder code storage portion 303 with the ladder codes 403B and 413B. 423B is stored.

When the ladder cords 403B, 413B, and 423B are stored in the ladder cord storage portion 303, the ladder cords 403B, 413B, and 423B have a shape recessed with respect to the surroundings and are fixed by being hooked on the hook portions 301A, 301B.

Since the slat angle fixture 300 is provided with the sliding portions 304G and 304I having no corners, the ladder cords 403B, 413B and 423B are smoothly stored in the ladder cord storage portion. Further, since the sliding portions 304A and 304C are inclined from the sliding portion 304B toward the ladder cord storage portion 303, the rings gradually expand when passing through the sliding portions 304A and 304C. ..

When the operator uses the sliding portions 304D, 304E, 304F, 304H, 304J when turning the ring protruding from the ladder cord insertion hole 302 toward the ladder cord storage portion 303 side, which is the back side of the exiting side. The same applies to.

As described above, in the present embodiment, when the ladder cords 403B, 413B, and 423B, which are heavy such as slats 401 and 402, are stored in the ladder cord storage portion 303, it is easy to slide the sliding portion 304 without corners. Can be stored in.

Further, the ladder cord accommodating portion 303 is formed into a groove shape and the shape of the ladder cord holding portion 305 is formed into a rhombus shape to prevent the slat angle fixture 300 from rotating in the horizontal direction. This makes it possible to stably open and close the slat 401 and 402 in the solar radiation adjusting device 400 even when the slat angle fixture 300 is attached. Further, the thickness of the slat angle fixture 300 is the same as or about twice the thickness of the ladder cords 403, 413 and 423 so as not to interfere with the opening and closing of the solar radiation adjusting device 400.

Since the ladder cords 403B, 413B, and 423B are under the weight of slat 401, 402 as tension, depending on the material of the slat 401 and ladder cords 403, 413, 423, it is necessary to turn the expanded ring to the back side. Difficult to do with. Therefore, when attaching the slat angle fixture 300 to the solar radiation adjusting device 400, the operator may use, for example, a reverse action tweezers as a ladder cord threader instead of a hand.

By using the counter-acting tweezers that have the functions of pinching and opening, the operator can pinch the ladder cords 403B, 413B, and 423B, unfold the pinched ring, and turn the unfolded ring to the back side. Can be done at once.

FIG. 11 shows a schematic view of the ladder cord threader 1100 according to the present embodiment. As shown in FIG. 11, in the ladder cord threader 1100 according to the present embodiment, the operation unit 1101 operated by being gripped and the pair of knob hands 1102 and 1103 intersect in the length direction and the width direction. And.

Further, the ladder cord threader 1100 according to the present embodiment has a mouthpiece portion 1105 in which the ladder cords 403, 413 and 423 for adjusting the angles of the plurality of slats 401 and 402 of the solar radiation adjusting device 400 are pinched by a pair of knobs 1102 and 1103. Be prepared.

Since the pair of knobs 1102 and 1103 intersect in the length direction and the width direction, when the user of the ladder cord threader 1100 presses the operation portion, the mouth tip portion 1105 opens and the pressing of the operation portion is stopped. The mouth part 1105 closes.

When the ladder codes 403, 413 and 423 are pinched with a pair of knob hands 1102 and 1103, the mouthpiece 1105 opens. The opening width, which is the width between the mouth tips when the mouth tip portion 1105 is opened, shall be the interval between the slats 401 and 402 in order to facilitate the holding of the ladder codes 403, 413 and 423 by the ladder code holding portion 305. Is desirable. The counteracting unit 1104 may have a mechanism for adjusting the opening width.

According to this embodiment, the angle of the slat can be easily adjusted for each part even in a general blind. Further, the slat angle fixture 300 can be attached to an arbitrary position of the solar radiation adjusting device 400, and the switching position of the slat angle is adjusted according to the installation position of the lighting plate to reduce the light shielding and lighting of the solar radiation adjusting device 400. The switching position can be adjusted.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the first embodiment, the ladder cord insertion hole 302 and the ladder cord holding portion 305 are integrated. On the other hand, in the second embodiment, the ladder cord insertion hole 302 and the ladder cord holding portion 305 are separated from each other, which is mainly different from the first embodiment. In the following, description of the same points as in the first embodiment will be omitted.

FIG. 5 shows the configuration of the slat angle fixture 500 according to the present embodiment. FIG. 5A is a perspective view of the slat angle fixture 500, and FIG. 5B is a sectional view taken along line VV in FIG. 5A. As shown in FIG. 5, the slat angle fixture 500 includes a ladder cord insertion portion 510 provided with a ladder cord insertion hole 511 and a ladder cord holding portion 520.

The slat angle fixture 500 according to the present embodiment is the same as the slat angle fixture 300 according to the first embodiment except that the ladder cord insertion portion 510 and the ladder cord holding portion 520 are separated. The description of the corresponding part is omitted. As for the correspondence between the slat angle fixture 300 and the slat angle fixture 500, the ladder cord holding portion 305 corresponds to the ladder cord holding portion 520.

Further, the hooking portion 301 (301A, 301B) corresponds to the hooking portion 521 (521A, 521B), the ladder code insertion hole 302 corresponds to the ladder code insertion hole 511, and the ladder code storage portion 303 corresponds to the ladder code storage portion 522. do.

The sliding portion 304 (304A, 304B, 304C, 304D, 304E, 304F, 304G, 304H, 304I, 304J) is the sliding portion 523 (523A, 523B, 523C, 523D, 523E, 523F, 523G, 523H, 523I, 523J). Corresponds to.

Since the ladder cords 403B, 413B, and 423B are subject to the weight of the slats 401, 402 and the like as tension, in the slatted angle fixture 300 according to the first embodiment, the ring expanded when attached to the solar radiation adjusting device 400 is placed on the back side. It is difficult to turn it into a ladder.

In the slat angle fixture 500 according to the present embodiment, when the operator attaches to the solar radiation adjusting device 400, the operator passes the ladder cords 403B, 413B, and 423B through the ladder cord insertion holes 511 once provided in the ladder cord insertion portion 510. ..

Here, the operator can create a state in which the weight of the slats 401, 402, etc. is not applied to the ring by grasping the ladder cord insertion portion 510 and the ladder cords 403B, 413B, 423B of the ladder cord insertion portion 510. can. Then, the operator holds the ladder codes 403B, 413B, and 423B by hanging an unweighted ring such as slats 401 and 402 on the ladder code holding unit 520.

According to the present embodiment, since the ladder cord inserting portion 510 and the ladder cord holding portion 520 are separated, the operator attaches the slat angle fixture 500 to the solar radiation adjusting device 400 as compared with the first embodiment. Workability can be improved.
