Japanese Patent Laid-Open No. 11-306819

  However, such a daylighting apparatus has the following problems to be solved. First, in the daytime when the sun is out, sunlight can be taken from the daylighting means, and the interior can be illuminated with the sunlight that has been taken, but at night when the sun goes down (or the sun is hidden in the clouds) In the case of rain, etc.), there is a problem that sunlight cannot be taken and indoors cannot be illuminated using this daylighting device. In order to solve such a problem, an illumination unit for illuminating the inside of the room may be disposed in the light guide unit. When the illumination unit is disposed, the illumination unit is connected to the light guide unit from the daylighting unit. Therefore, there is a new problem that sunlight from the daylighting means cannot be efficiently transmitted to the irradiating means. In addition, when the illumination means is arranged in the light guide means, when the inspection and repair of the illumination means is performed, the light guide means must be disassembled by removing the irradiation means. The maintenance work is complicated and time-consuming.

  Secondly, the light guide means is composed of a plurality of cylindrical members, and the number of cylinders corresponding to the connection interval between the daylighting means installed on the roof and the irradiation means installed on the indoor ceiling. The connection interval where the light guide means is installed hardly corresponds to the connection length where the required number of cylindrical members are connected, and in the majority of cases, the cylindrical member to be connected last is connected. The length of the member is cut to a predetermined length, and the connection length of the required number of cylindrical members is adjusted to match the connection interval between the lighting means and the illumination means. There is a problem that the above work is complicated, time is required for the work, and if the cutting length is wrong, the cylindrical member is wasted.

  Thirdly, the light guiding means for guiding sunlight from the daylighting means is formed in a cylindrical shape, and a circular light diffusing member as an irradiating means is disposed at the lower end portion of the light guiding means, and irradiation from the daylighting means is performed. It is formed in substantially the same outer shape up to the means. For example, when the indoor size to be attached is large, the space illuminated by sunlight can be increased by increasing the irradiation means (for example, the light diffusing member), and the indoor space can be matched. In the daylighting apparatus having such a configuration, there are problems that the daylighting means and the light guiding means become large so as to correspond to the outer shape of the irradiation means, the daylighting apparatus as a whole becomes larger, and a large installation space is required. Further, the outer shape of the irradiating means corresponds to the outer shapes of the daylighting means and the light guiding means. Therefore, it is difficult to devise the design, and there is a case that does not necessarily match the indoor decoration.

A first object of the present invention is to provide a daylighting device that can be provided with illumination means without blocking sunlight guided to the irradiation means through the light guide means.
A second object of the present invention is to provide a daylighting apparatus that can adjust the connection length of connecting a necessary number of cylindrical members as desired without cutting the cylindrical members constituting the light guiding means. Is to provide.

One end (upper end) of the cylindrical reflecting member 16 extends to the vicinity of the dome member 14, and the other end extends downward beyond the main body base 22 of the mounting main body 18. In addition, when attaching the daylighting device 2, a circular opening 30 for attaching the cylindrical reflecting member 16 is formed in the path plate 20.

  The light guide means 6 has a plurality of (three in the embodiment of FIG. 1) cylindrical members 32, 34, and 36 (actually tapered with some taper, but the degree of taper is small). A cylindrical member), and the cylindrical members 32, 34, and 36 and the enlarged cylindrical body 38 transmit sunlight from the daylighting means 4 in a predetermined direction (in this embodiment). A light guide space 39 for guiding the light guide space 39 is defined, and the inner peripheral surfaces of the cylindrical members 32, 34, and 36 and the enlarged cylindrical body 38 that define the light guide space 39 function as reflecting surfaces. In addition, when the length of the light guide means 6 becomes long, the cylindrical member 32 (34) is additionally connected.

  The cylindrical members 32 and 34 have substantially the same configuration, and are formed by bending the plate-like member 40 shown in FIG. In this embodiment, in one end portion 42 of the plate-like member 40, a first notch 44 is provided on one side portion (lower side portion in FIG. 3) in the width direction (vertical direction in FIG. 3), and the other side portion ( A second notch 46, a third notch 48, a fourth notch 50, and a fifth notch 52 are provided in this order from the outer side to the inner side in FIG. The sixth notch 54 is provided. The widths of the first to sixth cutouts 44 to 54 are substantially equal, and the depths of the first cutout 44 are the shallowest, the second cutout 46, the third cutout 48, The depths of the fourth notch 50 and the fifth notch 52 are increased in this order, and the depth of the pair of sixth notches 54 is substantially equal to the depth of the fourth notch 50.

  When forming the cylindrical member 32 (34), the one end part 42 and the other end part 56 of the plate-like member 40 are connected as follows. When the ordinary cylindrical member 32 (34) is formed, the other end portion 56 of the plate-like member 40 passes through the first notch 44 from the inside to the outside, and one of the pair of sixth notches 54 (the first notch) is formed. One end thereof so that the notch 44 side) passes from the outside to the inside, the other of the sixth notches 54 (the fifth notch 52 side) passes from the inside to the outside, and the second notch 46 further passes from the outside to the inside. 42, the plate-like member is connected between the first notch 44 and one sixth notch 54 and between the other sixth notch 54 and second notch 46. The other end 56 of the 40 is located outside the one end 42, and an adhesive tape, for example, is applied to the outer peripheral surface of the cylindrical member 32 (34) over the one end 42 and the other end 56 as necessary. In this way, the cylindrical member 32 (34 There is formed. In the cylindrical member 32 (34) thus formed, the depth of the second notch 46 is deeper than that of the first notch 44. Therefore, the other side (second notch 46 side) (cylindrical member 32, The outer diameter of one end portion of 34 is somewhat smaller than the outer diameter of one side portion (first notch 44 side) (becoming the other end portion of the cylindrical members 32, 34). The shaped member 32 (34) has a tapered shape in which the outer diameter gradually decreases from the other end toward one end.

  When the cylindrical member 32 (34) having a taper larger than the above-described normal shape is formed, the other end portion 56 of the plate-like member 40 is the same as the first notch 44 and the pair of sixth notches 54 described above. , And is connected to one end portion 42 so as to pass through the third notch 48 from the outside to the inside. In the cylindrical member 32 (34) thus formed, the depth of the third notch 48 is greater than that of the second notch 46, so that the outer diameter on one end side of the cylindrical member 32 passes through the second notch 46. The cylindrical member 32 (34) is somewhat larger in taper than the formed one. When the cylindrical member 32 (34) having a larger taper is formed, the other end portion 56 of the plate-like member 40 passes the first notch 44 and the pair of sixth notches 54 in the same manner as described above, and further One end of the 4 notch 50 (or the fifth notch 52) is connected to 42 so as to pass from the outside to the inside, and the depth of the fourth notch 50 (or the fifth notch 52) is the third notch. Since it is larger than the notch 48 (or the fourth notch 50), the formed cylindrical member 32 (34) has a somewhat greater degree of taper.

  In this example, since the cylindrical members 32 and 34 are formed using the common plate-like member 40, the degree of taper of both the cylindrical members 32 and 34 can be adjusted, but the light guide means 6 is assembled. In this case, as described later, the degree of taper of the cylindrical member 34 is adjusted, and the cylindrical member 34 that adjusts the degree of taper becomes the specific cylindrical member. In addition, instead of manufacturing the normal cylindrical member (32) and the specific cylindrical member (34) from the common plate-shaped member 40, the specific cylindrical member (32) is specified from the dedicated plate-shaped member, respectively. You may make it manufacture with a cylindrical member (34). In this case, the plate-like member of the normal cylindrical member (32) may be provided with, for example, a first notch 44, a second notch 46, and a pair of sixth notches 54, and a specific cylindrical member ( The plate-like member 34) may be the same as the plate-like member 40 shown in FIG. 3, for example.

  In this embodiment, the degree of taper of the cylindrical member 32 (34) can be changed to four stages, but it can also be configured to be changeable to two stages, three stages, or five stages or more. In this case, two, three, five or more notches having different depths may be provided on the other side of the plate-like member 40.

  Next, the cylindrical member 36 will be described. The cylindrical member 36 is also tapered like the cylindrical member 32 (34), and the outer diameter of one end thereof is somewhat larger than the outer diameter of the other end. It is getting smaller. Further, a shielding member 62 for shielding the light guide space 39 is provided at the lower part of the cylindrical member 36 so as to be openable and closable. In this connection, both ends of the sheet-like member are securely secured by, for example, rivets. A cylindrical member 36 is formed by being fixedly connected to the.

  A support shaft 64 is rotatably supported through the lower portion of the cylindrical member 36, and a shielding member 62 is attached to the support shaft 64 (portion located in the light guide space). The shielding member 62 has a disk shape, and is in an open state shown in FIG. 1 (a state indicated by a solid line in FIG. 4) and a closed state rotated by 90 degrees from this open state (a state indicated by a two-dot chain line in FIG. 4). It can freely rotate between. In the open state, the shielding member 62 is positioned in the vertical direction to open the light guide space 39, and sunlight from the daylighting means 4 is guided to the irradiation means 8 through the opened light guide space 39. In the closed state, the shielding member 62 is positioned in the horizontal direction to close the light guide space 39, and sunlight from the daylighting means 4 is shielded by the shielding member 62 and guided to the irradiation means 8 through the light guide space 39. There is nothing.

  In connection with the shielding member 62, a drive source (not shown) such as an electric motor is provided. The drive source is drivingly connected to the support shaft 64, and is driven to rotate in a predetermined direction to position the shielding member 62 in the open state, and is rotationally driven in a direction opposite to the predetermined direction to hold the shielding member 62 in the closed state. The shielding member 62 may be automatically opened and closed by, for example, a remote control operation using the driving force of the driving source in this way. Instead of such a configuration, an opening / closing operation lever extending indoors is provided, The shielding member 62 may be held in the open state by rotating the opening / closing lever in a predetermined direction, and may be held in the closed state by rotating in the direction opposite to the predetermined direction.

  This shielding member 62 is preferably configured as follows in relation to the stationary condensing reflector 17 of the daylighting means 4. That is, as shown in FIGS. 1 and 4, it is preferable that the support shaft 64 (which constitutes the turning axis) of the shielding member 62 is positioned substantially perpendicular to the stationary condensing reflection plate 17. Specifically, a central axis passing through the spherical center C of the stationary condensing reflection plate 17 (assuming that an angle in the circumferential direction of the stationary condensing reflection plate 17 is α, an axis passing through the center of the spherical center C and this angle α). Assuming L1, the axis of the support shaft 64 of the shielding member 62 (that is, the turning axis L2 of the shielding member 62) is substantially parallel to the central axis L1 in the vertical direction, in other words, the turning axis L2 is a stationary condensing reflector. It is desirable to configure it so that it is substantially perpendicular to 17. With this configuration, in the open state, the shielding member 62 extends in the vertical direction in a state perpendicular to the stationary condensing reflection plate 17, and sunlight guided to the irradiation means 8 through the light guide space 39 is reflected. The sunlight from the daylighting means 4 can be efficiently guided to the irradiation means 8 without being blocked.

  In the embodiment described above, the shielding member 62 is provided on the cylindrical member 36. However, when the sunlight from the daylighting means 4 is not shielded, the shielding member 36 and the related configuration can be omitted. When omitted in this manner, the cylindrical member 36 can be configured similarly to the cylindrical member 32 (34) described above.

  The enlarged cylindrical body 38 interposed between the cylindrical member 36 and the irradiation means 8 has a connecting portion 66 at one end and a circular enlarged portion 68 at the other end. The connecting portion 66 is formed in a cylindrical shape, and is short in the axial direction in this embodiment. The enlarged portion 68 extends in a conical shape so that the outer diameter gradually increases toward the other end, and an insertion end portion 70 is provided at the other end. For example, when the diameter of the light guide space 39 of the light guide means 6 (inner diameter of the cylindrical members 32, 34, 36) is about 30 to 45 cm, the diameter (insertion) of the irradiation side opening of the enlarged portion 68 of the enlarged cylindrical body 38 The inner diameter of the end portion 70) is about 50 to 70 cm. By configuring in this way, it is possible to increase the irradiation side opening of the light guide means 6 while keeping most of the daylighting means 4 and the light guide means 6 small. It is possible to irradiate a wide area of the indoor 7, and it is possible to brighten even a large indoor space.

  In this embodiment, the illumination means 72 is disposed in the enlarged cylindrical body 38. The illumination means 72 is for irradiating the indoor 7 (for example, living room), and when the expansion part 68 expands conically and the cross-sectional shape is circular, the annular illumination lamp 74, for example, annular fluorescence, is used. A lamp can be used conveniently. The annular illumination lamp 74 is located on the radially outer side of the light guide space 39 by the cylindrical members 32, 34, 36 and extends in an annular shape along the inner peripheral surface of the enlarged portion 68. With this configuration, the sunlight guided through the light guide space 39 by the cylindrical members 32, 34, and 36 is not blocked by the illumination means 72, and the sunlight from the daylighting means 4 is irradiated. 8 can be efficiently guided.

  When the illumination means 72 is provided in this way, as shown in FIG. 1, the shielding member 62 is provided so as to be freely opened and closed, and a specific surface of the shielding member 62 (a surface on the irradiation means 8 side in the closed state) is provided. A reflective surface is preferred. When the shielding member 62 is in the closed state, the light guide space 39 is closed, and the specific surface (the surface functioning as a reflecting surface) is held in a state facing the irradiation means 8 side. In this state, the illumination light illuminated from the illumination unit 72 toward the light guide space 39 is reflected by a specific surface (reflection surface) of the shielding member 62, and the reflected illumination light together with the illumination light from the illumination unit 72. Is irradiated from the irradiation means 8 to the indoor 7 and sunlight is not used, the indoor 7 can be efficiently illuminated using the illumination light of the illumination means 72. In addition, such a reflective surface can be formed by sticking an aluminum film.

  In order to guide the sunlight from the daylighting means 4 more efficiently, the shielding member 62 preferably has both surfaces as reflection surfaces. In such a configuration, the sunlight guided from the daylighting means 4 through the light guiding means 6 is reflected on the inner peripheral surfaces (functioning as reflecting surfaces) of the cylindrical members 32, 34, 36 and the enlarged cylindrical body 38. In addition, the light is reflected on both surfaces (functioning as a reflection surface) of the shielding member 62 and guided toward the irradiating means 8, so that sunlight can be guided more efficiently.

  The irradiation means 8 is attached to the indoor ceiling 12. The ceiling 12 is provided with an attachment opening having a shape corresponding to the outer diameter of the irradiation means 8, and the irradiation means 8 is attached to the attachment opening. The illustrated irradiation means 8 includes a diffusion cover 76 formed of transparent or translucent glass, synthetic resin, or the like, and the diffusion cover 76 is attached so as to close the mounting opening of the ceiling 12.

  The daylighting device 2 described above is installed on the roof 10 of the house as follows, for example. First, the tiles in a predetermined area of the roof 10 are removed to expose the field board 20, and the mounting body 18 is attached to the exposed field board 20. And the dome member 14 to which the stationary condensing reflection plate 17 is attached is attached to the upper end portion of the cylindrical support portion 24 of the attachment body 18 thus attached, and a cylindrical shape is attached to the inner peripheral surface of the cylindrical support portion 24. The reflection member 16 is attached.

  As described above, after attaching the daylighting means 4 to the roof 10, the light guide means 6 is connected to the reflecting member 16 of the daylighting means 4. As is understood from FIG. 1, the light guide 6 is connected by inserting one end portion of the cylindrical member 32 into the lower end portion of the reflecting member 16 and connecting the cylindrical member 32 to the reflecting member 16. Next, the cylindrical member 34 is inserted into the other end portion of the cylindrical member 32 to which the one end portion is connected, and the cylindrical member 34 is connected to the connected cylindrical member 32.

  At this time, the entire length of the light guide means 6 taking into account the cylindrical member 36 and the enlarged cylindrical body 38 to be connected later corresponds to the distance between the field board 20 of the roof 10 and the indoor ceiling 12. As described above, the degree of taper of the cylindrical member 34 is adjusted. 3 and 5, for example, when the cylindrical member 34 is manufactured using the first notch 44 and the second notch 46 of the plate-like member 40, the outer diameter on one end side of the cylindrical member 34. Is not so small and the degree of taper is small. Therefore, when the cylindrical member 34 manufactured in this way is inserted into the other end portion of the cylindrical member 32, an insertion state as shown by a one-dot chain line in FIG. The cylindrical member 34 is connected in a state of being slightly inserted into the upper cylindrical member 32. For example, when the cylindrical member 34 is manufactured using the first notch 44 and the fifth notch 52 of the plate-like member 40, the outer diameter on one end side of the cylindrical member 34 is reduced to some extent, and the degree of taper Therefore, when the cylindrical member 34 manufactured in this way is inserted into the other end of the cylindrical member 32, the cylindrical member 34 is inserted as shown by a solid line in FIG. It is connected in a state of being largely inserted into the member 32. Thus, by selecting the notch to be used when manufacturing the cylindrical member 34, the degree of taper can be adjusted. As a result, in the state where the cylindrical members 32 and 34 are connected to each other, It is possible to adjust within the range of the length D1, and this length adjustment can be performed without cutting the plate-like member 40.
