However, Patent Document 1 and Patent Document 2 also need to supply electric power from the outside of the pipe. Therefore, when connecting from an electric wire, installation becomes complicated. In addition, when power is supplied from an externally installed solar cell, the installation location of the solar cell becomes a problem. Further, when power is supplied from a battery, replacement of the battery becomes complicated.
An object of the present invention is to provide a tubular body having a lighting function that does not require external power.

In the tubular body of the present invention, a first space is formed between a long base material having a first accommodating portion and a second accommodating portion extending along the longitudinal direction and the first accommodating portion. A second light transmissive fixed to the long base material so that a second space is formed between the first light transmissive cover fixed to the long base material and the second accommodating portion. A cover, a solar cell module housed in the first housing part, lighting housed in the second housing part, and a storage battery that stores power generated by the solar cell module and supplies power to the lighting. It is characterized by having.
This tubular body is to be incorporated substantially horizontally on the installation surface in a part of a fence or the like along a road, stairs, slopes, or the like.

Since the tubular body of the present invention includes a solar cell module such as a solar cell panel, lighting, and a storage battery, it illuminates the surroundings along the tubular body without requiring external power. Can be done. That is, by directing the first accommodating portion accommodating the solar cell module toward the sun, the solar cell module can be efficiently exposed to sunlight through the first light transmissive cover that closes the first accommodating portion. It can generate electricity. On the other hand, the illumination can irradiate the outside with light in a predetermined direction through the second light transmissive cover.

It is preferable that the tubular body of the present invention has the second accommodating portion opened on the opposite side to the first accommodating portion. Here, the side opposite to the first accommodating portion means a direction having an angle of 90 degrees or less with respect to the lower side in the vertical direction when the first accommodating portion is directed upward in the vertical direction. In this case, for example, by incorporating the tubular body of the present invention into a guard fence or a fence-type handrail so that the first accommodating portion faces upward as a horizontal pipe, the second accommodating portion faces downward on the opposite side. Therefore, it is possible to illuminate a passage surface such as a sidewalk or a roadway along a guard fence or a fence-type handrail.

The tubular body of the present invention preferably has a circular cross-sectional shape. For example, when the tubular body of the present invention is used instead of a guard fence or a horizontal pipe of a fence-type handrail, a pedestrian can easily grasp the tubular body.

It is a front view which shows the fence type handrail using the tubular body of this invention. 2a is a side view showing the handrail main body of FIG. 1 (the first embodiment of the tubular body of the present invention), and FIG. 2b is a sectional view taken along line XX.

It is sectional drawing which shows the 2nd Embodiment of this invention.

FIG. 1 shows a fence-type handrail 100 using the tubular body of the present invention. The fence-type handrail 100 is fixed to the outside, and has two columns 101, a handrail main body (cylindrical body of the embodiment) 10 horizontally supported by the upper part of each column, and each column. It has a pipe 102 that is horizontally supported at the middle portion of the above. The columns 101 and pipes 102 are conventionally known. The support column 101 is provided with a bracket (not shown) for attaching the handrail main body 10 and the pipe 102.
The handrail main body 10 stores a solar cell module that receives sunlight to generate electricity, a storage battery that stores the power, lighting that emits light by the power of the storage battery, and stores the power generated by the solar cell module in the storage battery during the daytime. It is equipped with a control unit that emits light at night using the power of a storage battery. Therefore, the handrail main body 10 can provide a lighting function to the conventionally known fence-type handrail, and can illuminate the sidewalk along the fence-type handrail.

As shown in FIG. 2, the handrail main body 10 includes a long base material 11, a first light transmitting cover 12, a second light transmitting cover 13, and a solar cell module 14 housed in the long base material 11. A lighting 15 housed in the long base material 11, a storage battery 16 housed in the long base material 11, and a control unit 17 housed in the long base material 11 are provided. The cross-sectional shape of the handrail body 10 is circular. Further, lid members 18 are attached to both ends of the handrail main body 10. As will be described later, the lid material 18 may also serve as a bracket of the support column 101.
The size of the handrail main body 10 is 20 to 100 mm in diameter, preferably 30 to 80 mm.

As shown in FIG. 3a, the long base material 11 has a tubular shape having a first accommodating portion 21 and a second accommodating portion 26 extending along the longitudinal direction. Specifically, the cross section of the long base material 11 is the first arc A1 centered on the point on the upper side in the vertical direction from the center of the circle of the cross section of the handrail body 10, and 45 from the lower side in the vertical direction from the center of the circle of the cross section of the handrail body 10. Two arcuate first frames 11a1 (left side of FIG. 3a) and second frames 11a2 (FIG. 3a) forming a shape in which the second arc A2 centered on the point of degree is cut out from the circle of the cross section of the handrail main body 10. (Right side), one end of the first frame (upper end of FIG. 3a) and one end of the second frame (upper end of FIG. 3a) are connected in place of the first arc A1. 1 The accommodating portion 21, the other end of the first frame (lower end in FIG. 3a) and the other end of the second frame (lower end in FIG. 3a) are connected instead of the second arc A2. It is composed of a second accommodating portion 26. The first accommodating portion 21 opens or faces upward in the vertical direction. The second accommodating portion 26 opens or faces in a direction having an angle of 45 degrees with respect to the lower side in the vertical direction.

The angle α1 of the first arc A1 is larger than the angle α2 of the second arc A2. For example, when the handrail main body 10 has a cylindrical shape, the angle α1 of the first arc A1 is 45 to 180 degrees, preferably 90 to 180 degrees. If it is smaller than 45 degrees, the time of sunlight hitting the solar cell module housed in the first housing section 21 becomes short. Even if it is larger than 180 degrees, the time of sunlight that hits the solar cell module does not change much. The angle α2 of the second arc A2 can be appropriately selected depending on the purpose of lighting. For example, when illuminating a certain direction, it is 5 to 90 degrees, preferably 25 to 90 degrees.
The opening direction of the second accommodating portion 26 is not particularly limited as long as it does not overlap with the first accommodating portion 21. However, when the tubular body is used for a handrail or a guard fence, it is preferable that the second accommodating portion 26 is opened on the opposite side of the first accommodating portion 21. That is, when the center of the first accommodating portion 21 is opened upward in the vertical direction, it is preferable that the center of the second accommodating portion 26 is opened in a direction at an angle with respect to the lower side in the vertical direction. In this case, it is possible to illuminate the sidewalk or the roadway provided along the handrail at night.
The long base material 11 is molded from a metal such as steel or aluminum, or a hard synthetic resin. From the viewpoint of strength, metal extruded profiles, particularly aluminum or aluminum alloy extruded profiles, are preferable.

The first accommodating portion 21 has a first base portion 22 extending in the longitudinal direction and a pair of first locking portions 23 provided along both sides of the first base portion. The first accommodating portion 21 accommodates the solar cell module 14. Further, the first light transmissive cover 12 is connected to the first accommodating portion 21. The pair of first locking portions 23 are provided symmetrically with respect to the first base portion 22.
In the description of the first accommodating portion 21, the vertical plane F1 (passing through the center of the circle of the cross section of the handrail main body 10) that cuts the first accommodating portion 21 in half is centered on the inside, and the vertical plane is in the direction approaching the vertical plane F1. The direction away from F1 is the outside.

The first base portion 22 is a portion for mounting the solar cell module 14. Specifically, it is provided with a recess 22b extending in the longitudinal direction, and the solar cell module 14 is mounted so as to cover the recess 22b (see FIG. 2b). The space formed by the solar cell module 14 and the recess 22b is filled with a heat radiating material, an adhesive, or the like (see FIG. 2b). Further, the recess 22b is formed with a communication hole 22a through which a lead wire for electrically communicating the solar cell module 14 and the control unit 17 is passed.
As shown in FIG. 3b, the first locking portion 23 has a fitting groove 23a extending in the longitudinal direction and a locking groove 23b extending inward from the inner wall 23a1 of the fitting groove 23a near the bottom of the fitting groove 23a. Further, the outer wall 23a2 of the fitting groove 23a is lower than the inner wall 23a1, and a flat surface portion 23c extending outward from the upper end of the outer wall 23a2 is formed. The flat surface portion 23c and the end portion of the first frame 11a1 (or the end portion of the second frame 11a2) form a seal pocket CP extending in the longitudinal direction.

Next, the first light transmissive cover 12 connected to the first accommodating portion 21 will be described.
As shown in FIG. 4a, the first light transmissive cover 12 has a long cover main body 31 and a pair of first leg portions 32 protruding from the lower surface of the cover main body. The first light-transmitting cover 12 is made of a light-transmitting synthetic resin extruded body. In particular, those made of extruded products of polycarbonate resin and acrylic resin are preferable.

The cross section of the cover main body 31 is an arc-shaped plate material having substantially the same size as the first arc A1 notched in the cross section of the long base material 11. The convex side is the upper surface and the concave side is the lower surface. By bending in this way, sunlight can be efficiently collected in the first base portion 22 of the first accommodating portion 21.
The thickness of the cover body 31 is 0.8 to 10 mm, preferably 1 to 5 mm.
In the description of the cover main body 31, the direction approaching the vertical face F1 is inside, centering on the vertical face F1 that cuts the cover main body 31 in half (the same surface as the vertical face that cuts the first accommodating portion 21 in half). , The direction away from the vertical plane F1 is the outside.

As shown in FIG. 4b, the first leg portion 32 extends downward from a portion slightly inward from the side edge of the cover main body 31. At the lower end of the first leg portion 32, a first locking piece 32a that engages with the first locking portion of the first accommodating portion of the long base material is formed. Specifically, the first locking piece 32a includes an inclined tapered portion 32a1 extending inward from the lower end and a locking step portion 32a2 extending horizontally outward from the upper end thereof.
Further, the first leg portion 32 is elastically deformed so that the first locking piece 32a can move inward and outward, particularly outward, around the vicinity of the base end of the first leg portion 32.
The pair of first leg portions 32 are provided symmetrically with respect to the vertical plane. The distance between the pair of first leg portions 32 is substantially the same as the pair of fitting grooves 23a of the first base portion 22.

Next, the fixing structure of the first light transmissive cover 12 and the long base material 11 will be described.
The fixing structure of the first light transmitting cover 12 and the first accommodating portion 21 of the long base material 11 is such that the first leg portion 32 of the first light transmissive cover 12 and the first accommodating portion 21 are locked. It is formed by the fitting groove 23a of the portion 23. Specifically, by lowering the first light transmissive cover 12 from above the first accommodating portion 21, the tapered portion 32a1 of the first leg portion 32 comes into contact with the upper end of the inner wall 23a1 of the fitting groove 23a. By further lowering the first light transmissive cover 12, the tapered portion 32a1 slides on the upper end of the inner wall 23a1 of the fitting groove 23a, and at the same time, the first leg portion 32 is elastically deformed outward and the first leg portion 32 is fitted. It is inserted into the groove 23a. At the same time that the first locking piece 32a of the first leg portion 32 engages with the locking groove 23b of the first locking portion 23, the elasticity of the first leg portion 32 is released. In this way, it can be easily attached by simply moving the long base material 11 from the top to the bottom of the first accommodating portion 21.

The first leg portion 32 of the first light transmissive cover 12 is inserted into the fitting groove 23a of the first accommodating portion 21 from one end of the long base material 11, and the other end of the long base material 11 is inserted. You may slide it to the part. However, the longer the handrail body 10, the more complicated the work becomes. Further, in that case, if the liquid sealant 25 is used as described later, the sealant 25 is extruded from the other end of the long base material 11.
Further, the fixing structure of the first light transmissive cover 12 and the first locking portion 23 is not limited to the above. For example, the first accommodating portion 21 may be provided with a leg portion extending upward, and the first light transmissive cover 12 may be provided with a groove or the like for receiving the leg portion. At that time, as in the above embodiment, the first light transmissive cover 12 is moved from the upper side to the lower side of the first accommodating portion 21 of the long base material 11, and the first light transmissive cover and the long base material are engaged. It is preferable that the stop portions are clip-fitted to form a fixed structure. Further, the locking portions of the first light transmissive cover and the first accommodating portion may be fixed to each other with an adhesive or the like.

Next, a seal structure extending in the longitudinal direction provided between the first light transmissive cover 12 and the long base material 11 will be described.
The sealing structure between the first light transmitting cover 12 and the first accommodating portion 21 of the long base material 11 is the flat surface portion 23c of the first locking portion 23 of the first accommodating portion 21 and the first frame 11a1. It is formed by a liquid sealant 25 (particularly, a silicone-based sealant) filled in the seal pocket CP formed by the end portion (or the end portion of the second frame 11a2). Specifically, as shown in FIG. 2b, the first leg portion 32 of the first light transmissive cover 12 is inserted into the fitting groove 23a via the seal pocket CP filled with the sealant 25 in the longitudinal direction. A seal point extending to is formed.
However, the seal structure between the first accommodating portion 21 and the first light transmissive cover 12 is not limited to the above as long as it is continuously provided in the longitudinal direction. For example, an elastomer gasket sheet such as silicone rubber that extends from the flat surface portion 23c to the inner wall 23a1 of the fitting groove 23a and closes the fitting groove 23a may be supported. Further, as shown in FIG. 4c, a gasket sheet 25a may be provided between the lower surface of the end portion of the cover body 31 of the first light transmissive cover 12 and the first frame 11a1 (or the second frame 11a2). ..

Since it is configured in this way, by attaching the first light transmissive cover 12 above the first accommodating portion 21 of the long base material 11, the long base material 11 and the first light transmissive cover 12 can be attached to each other. A first space S1 (see FIG. 2) is formed between them, and the first base portion 22 to which the solar cell module 14 is mounted can be closed in the first space S1.
Further, after connecting the first light transmissive cover 12 and the long base material 11, the outer peripheral surface of the frame of the long base material 11 and the outer peripheral surface of the cover main body 31 of the first light transmissive cover 12 One large arc is formed. Therefore, it is excellent in aesthetics.

Next, the second accommodating portion 26 and the second light transmissive cover 13 will be described.
In these explanations, as shown in FIGS. 5a and 5b, the opening direction of the second accommodating portion 26 (outside the radial direction of the cross section of the handrail body) is upward, and the opposite direction (radial direction of the cross section of the handrail body) is upward. (Inside) is on the bottom. Further, the direction toward the central surface F2 is the inner side, and the direction away from the central surface F2 is the outer side, centering on the central surface F2 that cuts the second accommodating portion 26 and the second cover main body 41 in half.
The second accommodating portion 26 has a second base portion 27 extending in the longitudinal direction and a pair of second locking portions 28 provided along the second base portion on both sides of the second base portion. The pair of second locking portions 28 are provided symmetrically with respect to the second base portion 27. The second accommodating portion 26 accommodates the lighting 15.

The second base portion 27 is a portion to which the illumination 15 is mounted. Further, the second base portion 27 is formed with a communication hole 27a through which a lead wire for electrically communicating the illumination 15 and the control unit 17 is passed.
The second locking portion 28 has a pair of side walls 28a extending upward at both side ends of the second base portion 27, and a locking groove 28b extending outward near the lower portion of the side wall 28a.

As shown in FIG. 5b, the second light transmissive cover 13 has a long second cover main body 41 and a pair of second leg portions 42 protruding from the inner surface of the cover main body. Like the first light-transmitting cover 12, the second light-transmitting cover 13 is also made of an extruded body of a light-transmitting synthetic resin. In particular, one made of an extruded body of polycarbonate or acrylic resin is preferable.

The cross section of the second cover main body 41 is an arc-shaped plate material having substantially the same size as the second arc A2 notched in the cross section of the long base material 11. The convex side is the outer surface and the concave side is the inner surface. The thickness of the second cover main body 41 is 0.5 to 5 mm, preferably 0.8 to 3 mm.
The second leg portion 42 extends downward from a portion that has entered the inside from the side edge of the second cover main body 41. At the lower end of the second leg portion 42, a second locking piece 42a that engages with the locking groove 28b of the second locking portion of the long base material is formed. Specifically, the second locking piece 42a includes a tapered portion 42a1 that is inclined so as to extend from the lower end, and a locking step portion 42a2 that extends from the upper end to the horizontal side edge side. Further, the second leg portion 42 is elastically deformed so that the second locking piece 42a can move inward and outward directions, particularly inwardly, around the vicinity of the base end of the second leg portion 42.

The fixed structure of the second light transmitting cover 13 and the second accommodating portion 26 of the long base material 11 is the second locking of the second leg portion 42 of the second light transmissive cover 13 and the second accommodating portion 26. It is formed by the locking groove 28b of the portion 28. That is, only by moving the second light transmissive cover 13 from above to below the second accommodating portion 26 of the long base material 11, the second leg portion 42 is elastically deformed into the second accommodating portion 26. The second light transmissive cover 13 is connected to the second accommodating portion 26 by being inserted and engaging with the second locking piece 42a of the second leg portion 42 and the locking groove 28b.
As for the structure in which the second light transmitting cover 13 is fixed to the long base material 11, the second light transmitting cover 13 is moved from the upper side to the lower side of the long base material 11 as described above, and the second light transmitting is transmitted. It is preferable that the cover and the locking portion of the long base material are formed by clip-fitting each other. However, as with the fixed structure of the first light transmissive cover 12 and the first locking portion 23 of the long base material 11, the fixed structure thereof is not particularly limited. It may be fixed with an adhesive or the like.

Since it is configured in this way, by attaching the second light transmissive cover 13 above the second accommodating portion 26 of the long base material 11, the long base material 11 and the second light transmissive cover 13 can be attached to each other. A second space S2 (see FIG. 2) can be formed between them, and the second base portion 27 can be closed in the second space S2.
When the second light transmissive cover 13 and the long base material 11 are connected, the outer peripheral surfaces of the first frame and the second frame of the long base material 11 and the second cover of the second light transmissive cover 13 are connected. A single arc is formed with the outer peripheral surface of the main body 41, which is excellent in aesthetics.
In this embodiment, no seal structure is provided between the second accommodating portion 26 and the second light transmissive cover 13. This is because the second accommodating portion 26 is open downward, so that it is difficult for moisture to enter. However, in order to protect the lighting from moisture, a seal structure may be provided between the second accommodating portion 26 and the second light transmissive cover 13.

The solar cell module 14 has a substrate and a solar cell arranged on the substrate. The area of the solar cell module 14 may be selected according to the lighting to be used. For example, considering that the power generation depends on the weather and that there is a power loss due to filling the storage battery, it is possible to generate more power than the power consumed in a day by lighting.

Examples of the lighting 15 include those that emit light by electric power such as LEDs, fluorescent lamps, and light bulbs. In particular, considering that the electric power generated by the solar cell module is used, an LED having a small power consumption is preferable.

The storage battery 16 stores the electric power generated by the solar cell module 14. The capacity enables the solar cell module 14 to store the electric power that can be produced in one day. The storage battery 16 is provided in the internal space of the long base material 11. However, the place of arrangement is not particularly limited, and may be arranged in the first accommodation part 21 or the second accommodation part 26.

The control unit 17 stores the power generated by the solar cell module in the storage battery during the daytime, and uses the power of the storage battery to emit light at night. For example, switching between daytime and nighttime is performed depending on the ambient illuminance. Further, the switching may be automatically performed by a timer. Further, at night, a sensor or the like may be used to detect that a person, a car, or the like is approaching, and when the sensor or the like is detected, the lighting may be turned on for a predetermined time. The control unit 17 is provided in the internal space of the long base material 11.

As shown in FIG. 6, the lid material 18 has a bottomed tubular shape, and a disk-shaped sealing material 18b is provided on the surface of the bottom portion 18a. The lid material 18 covers the end portion of the long base material 11 to seal the inside of the long base material 11. Specifically, by covering the end portion of the long base material 11 with the lid material 18, the end portions of the first frame, the second frame, the first base portion, and the second base portion come into contact with the sealing material 18b, and each space is created. It is sealed. In the method of fixing the lid material 18 to the long base material 11, after the lid material 18 is attached to the long base material 11, the tubular portion of the lid material 18 is fitted to the long base material 11 and fixed. However, the fixing method is not particularly limited. For example, after connecting, a part of the cylinder portion of the lid material 18 may be caulked, or an adhesive or the like may be used. As described above, both ends of the spaces S1 and S2 of the handrail main body 10 may be closed by the bracket of the support column 101.

By using the tubular body (handrail main body 10) of the embodiment for an outdoor guard fence, fence-type handrail, or the like, it is possible to impart a lighting function to the guard fence, fence-type handrail, or the like. Furthermore, since it has a solar cell module, a storage battery, and a control unit inside, it does not require external power and is easy to install. Further, by connecting the long base material 11, the first light transmitting cover 12, and the second light transmitting cover, the shape becomes cylindrical, which is excellent in aesthetics.
The cross-sectional shape of the tubular body may be another shape. For example, the cross section may be triangular or polygonal as in the handrail main body 10a of the second embodiment shown in FIG. 7. In this case, the lid member 18 and the bracket of the support column also exhibit a shape corresponding to the handrail main body 10a. Other configurations are substantially the same as the handrail body 10 of FIG.
