Description

  The present invention relates to a daylighting apparatus that illuminates the interior by introducing light from the sun indoors.

  Conventionally, a method of installing a skylight on a roof has been used as a daylighting method in which light from the sun is introduced indoors and the interior is illuminated by the light from the sun. However, since the skylight can be installed only in a house having a structure in which the roof can be directly seen from the inside, there is a problem that it is often difficult to install in existing houses.

  Therefore, in recent years, as a daylighting method that can also be applied to existing houses, a daylighting means that is provided on the roof and introduces light from the sun, and a cylindrical shape that guides light from the daylighting means in a predetermined direction while reflecting the light from the inner surface There has been proposed a method of using a daylighting device including a light guiding unit and an irradiation unit that is provided on a ceiling and irradiates light from the light guiding unit indoors (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 11-306819

  However, the conventional daylighting apparatus as described above has the following problems. First, when the light guide means is disposed on the attic or the like, the light guide means is set according to the relative positional relationship between the daylighting means and the irradiation means or according to the size of the space such as the attic. It is necessary to arrange it while bending it at a predetermined location. At this time, since the light guide means is formed of a cylindrical member such as a pipe or a duct having no flexibility, a cylindrical member bent in advance at a predetermined angle and a linear cylindrical member are provided. The light guide means is bent at a predetermined position by joining together. In this case, since the relative positional relationship between the daylighting unit and the irradiation unit, the size of the space such as the attic, and the like vary depending on the house where the daylighting apparatus is installed, for example, 10 degrees, 15 degrees, 30 degrees, or 45 It is necessary to prepare a cylindrical member bent in advance at various angles such as degrees, and there is a problem that the manufacturing cost increases. Further, for example, since the bending angle of the tubular member bent at an angle of 30 degrees cannot be finely adjusted to an angle of 32 degrees, the degree of freedom when arranging the light guiding means while bending is reduced, There is also a problem that the light guide means may not be properly disposed.

  2ndly, when installing a daylighting apparatus in the house where the roof tile was laid, it is necessary to attach a daylighting means to a field board. However, since the shape of the roof tile is complicated, it is difficult to match the shape of the daylighting means with the shape of the roof tile adjacent to the daylighting means. For this reason, there is a problem that a gap is formed between the daylighting means and the roof tile, and rainwater enters from this gap and causes rain leakage.

  Thirdly, in the conventional daylighting apparatus, the other end of the light guide means is attached to the irradiation means via a fixing member such as a fixing ring, for example, and the fixing member is fixed to the ceiling by screwing. By doing so, the light guide means and the irradiation means were fixed to the ceiling. In such a mounting structure, when the ceiling is made of a wood board such as a plywood board, the ceiling has a base for screwing, so the fixing member can be fixed to the ceiling by screwing. Met. However, in recent years, an increasing number of houses have ceilings made of plasterboard (fired gypsum as the main raw material, covered with both sides of core material with board base paper and rolled into a plate shape) having fireproof and sound insulation properties. And if it is the ceiling of this plaster board, the plaster board does not have a base for screwing, so the fixing member cannot be fixed to the ceiling by screwing, and the lighting device can not be easily constructed There was a problem.

  Fourthly, the light guiding means of the daylighting device is constructed by cascading a plurality of tubular members having an outer diameter at one end somewhat smaller than the outer diameter at the other end and having a slight inclination (ie, taper). Has been. It is difficult to taper the cylindrical member in terms of processing, and due to variations in processing accuracy, the light guiding unit becomes distorted when a plurality of cylindrical members are joined together to form a linear light guiding unit. Therefore, there is also a problem that the light guide means cannot be properly disposed.

  Fifth, in a room (for example, a living room) of a house, a ventilator may be installed to ventilate the room. In such a case, since the lighting device and the ventilation device are separately installed in one room, there is a problem that the installation work is complicated and the installation cost is high. Moreover, since the ventilation part of the ventilation device and the irradiation means of the daylighting device are provided on the indoor side, it is not preferable as the interior of the room.

  Sixth, at night when sunlight cannot be obtained, indoors cannot be illuminated by the daylighting device. Therefore, an electric lamp such as a fluorescent lamp must be installed on the indoor ceiling separately from the irradiation means by the daylighting device. did not become. Therefore, since the illumination means and the light by the daylighting device are separately installed in one room, the installation work is complicated, the installation cost is high, and it is not preferable as the interior of the room.

The roof tile 28c is adjacent to the one end 32 side of the base 20 so that each end of the roof tile 28c overlaps the one end 32 of the base 20 so that the base plate 18 Lay neatly. Since the first upper protruding wall portion 26 of the base portion 20 is formed in a corrugated shape corresponding to the inner shape of the lower end portion of the roof tile 28a, the upper end portion 26 and the base portion of the base portion 20 are the same as described above. It is possible to substantially eliminate the gap between the lower end portion of the roof tile 28a adjacent to the upper side of the portion 20. Further, since the second upper protruding wall portion 32 of the base portion 20 is formed in a step shape corresponding to the step shape of the roof tile 28c, the base portion 20 and the one side end portion 32 and the base portion 20 are similar to the above. It is possible to substantially eliminate the gap between the end of the roof tile 28c adjacent to the one end 32 side of the base 20.

  A seal member 58 made of a rubber tube or the like is formed in the gap between the first upper projecting wall portion 26 of the base portion 20 and the lower end portion of the roof tile 28a adjacent to the upper end portion side of the base portion 20 (FIG. 1), and a gap between the second upper projecting wall portion 32 of the base portion 20 and the end portion of the roof tile 28c adjacent to the one end portion side of the base portion 20. Also, the seal member 60 is inserted in the same manner. Therefore, since the space between them is hermetically sealed by the seal members 58 and 60, it is possible to reliably prevent rainwater from entering between them. As described above, the daylighting means 6 is attached to the roof 4, and after the attachment, the dome member 14 is attached to the support portion 22 of the attachment member 16 as required.

In such an attachment state, since the predetermined region on the lower surface side of the base portion 20 is formed to be on the same plane, the lower surface of the base portion 20 is in contact with the upper surface of the base plate 18 without backlash. The base 20 can be securely fixed to the base plate 18. Further, between the lower surface of the base portion 20 and the base plate 18, seal members 48 and 50 respectively attached to the ring-shaped recess 44 and the U-shaped recess 46 are interposed. Even when rainwater permeates between the lower surface of the base portion 20 and the base plate 18, the rainwater moves downward along the seal member 50 attached to the U-shaped recess 46 as indicated by an arrow P in FIG. It is possible to prevent rainwater from collecting in this gap by flowing down to the lower end 30 side of the base 20. If rainwater accumulates in this gap, there is a risk of entering the house through the opening 53 provided in the field board 18, but this seal member 50 can prevent rainwater from collecting in this gap, and as a result, leakage of rain in the house Can be reliably prevented. Further, the seal member 48 attached to the ring-shaped concave portion 44 acts in the same manner as the seal member 50 of the U-shaped concave portion 46, preventing rainwater from entering the house through the opening 53 provided in the field plate 18, by a double sealing structure according to members 48 and 50, the incoming immersion into the house rainwater can be prevented more reliably.

  Furthermore, since the ring-shaped protrusion 42 is provided on the outer peripheral part of the support part 22 on the upper surface of the base part 20, the rainwater is shown by an arrow Q in FIG. The water flows downward along the portion 42 (on the lower end portion 30 side of the base portion 20), and rainwater does not accumulate on the base portion 20. Therefore, the ring-shaped protrusion 42 defines a rainwater flow path on the upper surface of the base part 20 and can prevent rainwater from collecting on the base part 20 and leaking into the house.

  Next, returning to FIG. 1 again, the light guide means 8 will be described. The illustrated light guide means 8 is configured in a hollow cylindrical shape, and a first cylindrical member 62 mounted on the support portion 22 of the daylighting means 6; A second cylindrical member 64 mounted on the irradiation means 12 (described later), and a third cylindrical member 66 (66a, 66b) connected between the first cylindrical member 62 and the second cylindrical member 64.

The other open ends of the first cylindrical body 72 and the second cylindrical body 74 are each configured to be substantially perpendicular to the axis C. As shown in FIG. 7, the illustrated angle adjusting mechanism includes a fitting protrusion 76 provided at one opening end (the upper opening end in FIG. 7) of the first cylindrical body 72, and the second cylindrical body. 74 is formed with a fitting recess 78 provided at one opening end of 74 (lower opening end in FIG. 7). The fitting protrusion 76 that protrudes somewhat in the radial direction of the first tubular body 72 is slidably fitted into the fitting recess 78 of the second tubular body 74, and is thus fitted. The fitting projection 76 and the fitting recess 78 can slide relative to each other. As a result, the first cylindrical body 72 and the second cylindrical body 74 are rotatable with respect to each other.

In this case, in this case, the bending angle becomes zero (zero), and the second state shown in FIG. 6 (the second cylindrical body 74 is inclined 45 degrees with respect to the first cylindrical body 72). The second cylindrical body 74 is rotated relative to the first cylindrical body 72 as shown by the arrow in FIG. 6 until the bending angle becomes 45 degrees in this case. By rotating in this way, the second cylindrical body 74 can be bent to an arbitrary angle in the angle range of 0 to 45 degrees with respect to the first cylindrical body 72. it can.

  As shown in FIG. 6, the maximum bending angle of the second cylindrical body 74 with respect to the first cylindrical body 72 is 45 degrees. In this bent state, the axis of the second cylindrical body 74 (in FIG. 6) The two-dot chain line shown) is inclined 45 degrees with respect to the axis C. Therefore, the first cylindrical member 62 and the second cylindrical member 64 can be bent at an arbitrary angle within an angle range of 0 to 45 degrees. It should be noted that the inclination angle of one open end of the first cylindrical body 72 and the second cylindrical body 74 with respect to the axis C is not necessarily strictly 45 degrees, and there is a practical problem even if it is slightly deviated therefrom. Absent.

  In the present embodiment, the case where two third cylindrical members 66 (66a, 66b) are used has been described. However, according to the difference between the installation height of the lighting means 6 and the installation height of the irradiation means 12, that is, the first What is necessary is just to set the number of the 3rd cylindrical members 66 suitably according to the distance between the 1 cylindrical member 62 and the 2nd cylindrical member 64. FIG. As described above, the length of the light guide means 8 can be arbitrarily adjusted by appropriately setting the number of the third cylindrical members 66.

  Next, the irradiation unit 12 will be described. The illustrated irradiation unit 12 includes a hemispherical diffusion cover 98 formed of, for example, translucent glass or plastic (see FIG. 1). A plurality of arcuate protrusions 99 (three in this embodiment) are provided in the opening of the diffusion cover 98 so as to protrude inward in the radial direction. The diffusion cover 98 diffuses the light guided while irregularly reflecting the inside of the light guide means 8 to irradiate the room, and illuminates the room using sunlight. A second cylindrical member 64 is attached to the irradiation means 12 via a fixing ring 96, and the second cylindrical member 64 and the irradiation means 12 are fixed by fixing the fixing ring 96 to the indoor ceiling 10. It can be fixed to the ceiling 10. Hereinafter, a method for fixing the fixing ring 96 to the ceiling 10 will be described with reference to FIGS. 10 and 11.

  The fixing ring 96 includes a cylindrical portion 100, a contact piece 102 protruding outward from an outer peripheral portion of one end (lower end in FIG. 11) of the cylindrical portion 100, and a ring protruding to one side of the contact piece 102. A mounting portion 103, a concave groove portion 104 projecting inwardly from an inner peripheral portion of one end of the cylindrical portion 100, and a ring-shaped decorative portion 106 provided on the outer peripheral portion of the contact piece 102 (see FIG. 11). A plurality of insertion holes 108 (described later) and fixing holes 110 (described later) are provided in the contact piece 102 at intervals in the circumferential direction, and the fixing holes 110 are radially outward from the insertion holes 108. Is provided. A plurality (three in this embodiment) of long grooves 105 are provided on the outer periphery of the ring-shaped mounting portion 103.

  When the fixing ring 96 is attached, a circular ceiling opening 112 is provided in the ceiling 10, and the other end portion of the second tubular member 64 is exposed from the ceiling opening 112. Then, the locking piece 70 provided at the other end of the second cylindrical member 64 is inserted into the concave groove portion 104 of the fixing ring 96, and the locking piece 70 of the second cylindrical member 64 and the fixing ring 96 are further inserted. A fixing tube member 114 formed of rubber or the like is inserted between the cylindrical portion 100 and the second cylindrical member 64 is securely attached to the fixing ring 96 in this way. Then, if necessary, for example, an aluminum tape 116 or the like is attached to the joint between the second cylindrical member 64 and the fixing ring 96, and the second cylindrical member 64 is securely attached by the fixing ring 96. .

  Thereafter, the fixing band 118 is inserted into the plurality of insertion holes 108 provided in the fixing ring 96 by a predetermined length. The fixing band 118 is made of, for example, plastic, and includes a contact portion 120 having a predetermined thickness and a band portion 122 extending from the contact portion 120. The band portion 122 is provided with a plurality of locking claws 124 that are locked in the insertion holes 108 of the fixing ring 96 at intervals in the longitudinal direction. When the band portion 122 is inserted into the insertion hole 108, one of the locking claws 124 is locked to the insertion hole 108, thereby preventing the fixing band 118 from being pulled out.

  When fixing to the ceiling 10, the cylindrical portion 100 of the fixing ring 96 is inserted into the ceiling opening 112, and the contact portion 120 of the fixing band 118 is passed through the ceiling opening 112 to the upper surface side (ceiling back side) of the ceiling 10. And the abutment piece 102 of the fixing ring 96 is arranged on the lower surface side (inside the room) of the ceiling 10, and then the band portion until the abutting portion 120 of the fixing band 118 contacts the upper surface of the ceiling 10. Pull 122 downward (in the direction indicated by arrow X in FIG. 10). When pulled in this manner, the ceiling 10 is sandwiched between the contact portion 120 of the fixing band 118 and the contact piece 102 of the fixing ring 96, and the fixing ring 96 is securely attached to the ceiling 10 (see FIG. 11). In this attached state, the contact portion 120 of the fixing band 118 is positioned above the fixing hole 110 provided in the fixing ring 96, and one of the locking claws 124 of the band portion 122 is inserted through the fixing ring 96. Since the fixing band 118 is securely attached to the fixing ring 96 because it is locked in the hole 108, in such an attachment state, the extra band portion 122 extending downward from the contact piece 102 of the fixing ring 96 is It is cut by a cutter (not shown).

  After mounting in this manner, a screw member 126 such as a screw is inserted into the fixing hole 110 provided in the fixing ring 96 and screwed to the abutting portion 120 of the ceiling 10 and the fixing band 118 through the fixing hole 110. In this way, the fixing ring 96 is fixed to the ceiling 10. At this time, the head of the screw member 126 is embedded in a screw member hole (not shown) provided in the contact piece 102, and the head of the screw member 126 is placed on the lower surface side (indoor side) of the contact piece 102. ) On substantially the same plane. Further, a fixing ring 96 and a decorative screw 109 of the same color, for example, are attached to the head of the screw member 126, and when the irradiation means 12 is looked up from the room, the head of the screw member 126 is passed through the diffusion cover 98. The part is not visible and looks good. Therefore, even if the ceiling 10 is made of a material that does not have a screw-fastening base such as a plaster board, the contact portion 120 of the fixing band 118 can be used as the screw-fastening base. It becomes possible to securely fix the fixing ring 96 to the ceiling 10.

  In this way, the diffusion cover 98 as the irradiating means 12 is mounted on the ring-shaped mounting portion 103 provided on the fixing ring 96 attached to the ceiling 10. Specifically, each protrusion 99 of the diffusion cover 98 is inserted into each long groove 105 provided in the ring-shaped mounting portion 103, and the diffusion cover 98 is rotated in a predetermined direction so that each protrusion 99 is securely inserted into each long groove 105. The diffusion cover 98 is mounted on the ring-shaped mounting portion 103 by being locked to the ring-shaped mounting portion 103. Moreover, the ring-shaped decoration part 106 is arrange | positioned at the outer peripheral part of the spreading | diffusion cover 98, and it becomes possible to improve indoor interior property as what decorates the irradiation means 12. FIG. Of course, the fixing ring 96 can be configured without providing the ring-shaped decorative portion 106.

  The daylighting by the daylighting apparatus 2 described above is performed as follows. The sunlight is collected from the daylighting means 6, and the light introduced through the dome member 14 of the daylighting means 6 is reflected on the concave surface side of the reflection plate 24 mounted in the dome member 14 to the light guide means 8. Led. The light guided to the light guide 8 is irradiated in a predetermined direction (irradiation) while irregularly reflecting the inner peripheral surfaces of the first cylindrical member 62, the third cylindrical member 66 (66a, 66b), and the second cylindrical member 64. (Direction in which the means 12 is located). The light thus guided is emitted from the second cylindrical member 64, and the emitted light is diffused by the diffusion cover 98 to irradiate the room, and thus the room is illuminated using sunlight. Is done. In FIG. 1, only a part of the sunlight path guided into the room is shown in a simplified manner. In this way, it is possible to illuminate the interior by introducing light from the sun into the room by the daylighting device 2 during the daytime, and it is not necessary to use an electric lamp, which is very economical.

  In the daylighting device 2 described above, an illumination device can be incorporated so that illumination light can be obtained even at night when sunlight cannot be used. 12 and 13, the illustrated lighting device 2 is provided with a lighting device 180 in the second cylindrical member 64. The illuminating device 180 includes a light source 182 such as a light bulb having a socket portion 192 and a rod-like support 184 that supports the light source 182. A mounting portion 186 for mounting the light source 182 is provided at the center of the support 184, and a socket hole for mounting the light source 182 by inserting the socket portion 192 into the lower end of the mounting portion 186. (Not shown) is provided. The socket portion 192 is inserted into a socket hole provided in the attachment portion 186, and the light source 182 is detachably attached to the support body 184. Further, from the mounting portion 186, support wing portions 188 and 188 extend in opposite directions. The support wing 188 has a substantially triangular cross section perpendicular to the longitudinal direction (see FIG. 13), and a fixed piece 190 is provided at the tip of the support wing 188.

  Here, a method of mounting the lighting device 180 in the second tubular member 64 will be described. First, two mounting holes 194 for mounting the lighting device 180 are provided in the side surface portion of the second cylindrical member 64. Then, the lighting device 180 is mounted in the second cylindrical member 64 by inserting the fixing pieces 190 provided on the support wing portions 188 into the mounting holes 194, respectively. At this time, in the cross section perpendicular to the axial direction of the second cylindrical member 64, the light source 182 is located at a substantially central portion in the second cylindrical member 64, and the Y- In the cross section taken along line Y ′, the apex of the triangle faces upward (the upper side in FIG. 13). The fixed pieces 190 are exposed to the outside through mounting holes 194 provided in the side surface portion of the second cylindrical member 64, respectively. A power cable for supplying power from one fixed piece 190 to the light source 182 ( (Not shown) extends. Furthermore, the illumination device 180 is mounted at a height position of about 10 to 20 cm from the other end of the second cylindrical member 64.

  Next, an illumination method using the daylighting device 2 will be described. In the daytime when light from the sun is obtained, the light source 182 of the lighting device 180 is not turned on, and the interior is illuminated only with light from the sun introduced by the daylighting means 6. That is, the light introduced by the daylighting means 6 and guided in a predetermined direction while irregularly reflecting the inner surface of the light guide means 8 is a space defined between the inner surface of the second light guide means 64 and the outer surface of the support 184. (See FIG. 13) and guided to the irradiation means 12. At this time, the bottom of the support wing 188 faces downward (lower side in FIG. 13) and the top of the support wing 188 faces upward (upper side in FIG. 13). It is not attenuated, and the diffuse reflectance of light can be maintained in substantially the same manner as in the case where the lighting device 180 is not provided. In this way, the light emitted from the second cylindrical member 64 is diffused by the diffusion cover 98 and irradiated indoors to illuminate the interior.

  On the other hand, at night when light from the sun cannot be obtained, the light source 182 is turned on, and the light from the light source 182 is diffused by the diffusion cover 98 to illuminate the interior. At this time, part of the light from the light source 182 is reflected by the inner surface of the second cylindrical member 64, and the interior is illuminated by both the reflected light and the direct light from the light source 182. As described above, since a part of the light from the light source 182 is reflected by the inner surface of the second cylindrical member 64, the light amount (brightness) of the light irradiated by the irradiation unit 12 is increased. Even when a light bulb having a relatively small wattage (for example, 40 W) is used, the same brightness as that obtained when the indoor light is irradiated with a light bulb having a relatively large wattage (for example, 60 W) can be obtained.

  In this way, light from the sun is introduced indoors during the daytime to illuminate the interior, and at night, the light source 182 of the illuminating device 180 is turned on to illuminate the interior, thereby providing a fluorescent lamp in addition to the irradiation means 12. It is not necessary to separately provide a lighting fixture (not shown) such as the ceiling 10. Therefore, since it is possible to illuminate the interior by the daylighting device 2 regardless of whether it is daytime or nighttime, it is only necessary to provide the irradiation means 12 by the daylighting device 2 on the ceiling 10, which is excellent in economic efficiency and interior interior characteristics. Will not be damaged.

  Next, another embodiment of the daylighting apparatus will be described with reference to FIGS. 14 and 15.

  The lighting means 6B configured as described above is attached to the roof 4B as follows. The roof 4B is composed of a field board (not shown) formed of plywood or the like, and a plurality of colonials 206 (a kind of roofing material) laid on the field board. First, the position of the roof 4B to which the daylighting means 6B is attached is determined, the plurality of colonials 206 at this position are removed to expose the field plate, and the field plate has a circular shape corresponding to the through hole 38B provided in the base portion 20B. Opening (not shown) is formed. Further, a part of the colonial 206a laid around the opening provided in the base plate is provided with an arc-shaped notch corresponding to the opening (see FIG. 18).

  When placing the base portion 20B on the roof 4B, the upper half (the upper region in FIG. 18) of the base portion 20B is placed on the base plate, and the lower side of the base portion 20B. Half (the lower region in FIG. 18) is placed on the colonial 206b. Then, the colonial 206c is laid on the upper half of the base portion 20B so that the removed colonial 206c overlaps the upper half of the base portion 20B. The colonial 206c laid on the upper half of the base portion 20B is provided with arc-shaped notches corresponding to the outer peripheral portion of the support cylinder portion 202 of the base portion 20B (see FIG. 18). When laying 206c, the support cylinder part 202 of the base part 20B does not get in the way.

In this way, by deforming the shape of the base portion 20B and matching the shape of the base portion 20B with the shape of the colonial 206, the one end 210 and the other end 212 of the base 20B and the colonial 206 are matched. It is possible to substantially eliminate the gap between the two.

  In addition, since the upper end 208 of the base 20B is folded inward, rainwater enters from the gap between the base 20B and the colonial 206c laid on the upper half of the base 20B. However, rainwater can be blocked by the upper end 208 folded back inward. Furthermore, since the one side end portion 210 and the other side end portion 212 of the base portion 20B are also folded back inward, rainwater flows into the one side end portion 210 and the other side end portion 212 of the base portion 20B. It is possible to block the intrusion into the gap between the adjacent colonials 206. In addition, since the lower end portion 214 of the base portion 20B is bent downward, it is possible to prevent rainwater from collecting on the base portion 20B during rainfall. In this embodiment, since the base part 20B can be freely deformed in accordance with the shape of the roof material, it can be applied to a roof on which various roof materials such as colonial and tin are laid.
