[0008] [Embodiment 1] A handrail 1 according to a first embodiment of the present invention will be described. In the following description, the same reference numerals in different drawings indicate parts with the same functions, and duplicated descriptions in each drawing will be omitted as appropriate.

[0009] [Overall configuration] FIG. 1 is a partially exploded perspective view of a handrail 1 according to a first embodiment of the present invention, as viewed from the inside in an installed state. FIG. 2 shows (a) a longitudinal cross-sectional view at the position of the support post 2, (b) a longitudinal cross-sectional view at the position of the auxiliary support post 6, and (c) a horizontal cross-sectional view of the handrail 1 of embodiment 1 of the present invention in an installed state. FIG. 3 is a perspective view of the handrail 1 of the first embodiment of the present invention, seen from the outside in a partially disassembled state. FIG. 4 shows a partially disassembled handrail according to the first embodiment of the present invention, with (a) a vertical cross-sectional view at the position of the temporary support post 6, (b) a view from the outside, and (c) a horizontal cross-sectional view. As shown in Fig. 1, the handrail 1 has pillars 2 erected on the balcony floor (pillar erection surface) 7 of the building, a coping 3 installed so as to span the upper ends of the pillars 2, and a lower chord 4 installed so as to span the lower parts of the pillars 2, and a solar panel 5 is held in an opening formed by the pillars 2, coping 3, and lower chord 4. In other words, the pillars 2, coping 3, and lower chord 4 function as a holding frame for the solar panel 5. In addition to the support pillars 2, additional support pillars 6 for accommodating wiring for the solar panels 5 are erected between the top board 3 and the floor 7. A wiring conduit 71 is buried in the floor 7, and wiring 8 from the solar power generation panel 5 is introduced into the building.

[0010] [Prop] The support pillars 2 are set up vertically on the floor 7. A plurality of support pillars 2 are set up at appropriate intervals in the extension direction of the handrail 1. Two support pillars 2 are shown in each drawing. A support frame 21 for supporting the side end of the solar panel 5 is attached to the support pole 2 so as to extend in the longitudinal (up-down) direction on the outer side of the support pole 2. A groove 211 for holding the solar panel 5 is formed in the support frame 21, and the side edge of the solar panel 5 is inserted into the groove 211 to hold the solar panel 5 (see FIG. 2(c)). In addition, a pillar base cover 22 is installed at the boundary between the pillar 2 and the floor 7 to cover and conceal this boundary. This pillar base cover 22 improves the design of the base of the pillar 2 (see Figure 1).

[0011] [Kasagi] The coping board 3 is attached so as to span the upper ends of the two support posts 2. The coping board 3 has a coping board receiver 31 attached directly to the support posts 2 and a coping board cover 32 attached to the top of the coping board receiver 31 (see FIG. 1, etc.). The coping block receiver 31 is attached with a screw to the upper end of the support pole 2. The coping block cover 32 is attached to the coping block receiver 31 by engaging with the coping block receiver 31 from above. The coping support 31 has a groove 311 extending longitudinally (left and right) on the outer side for holding the upper end of the solar panel 5. The groove 311 is formed to open downward, and the upper edge of the solar panel 5 is inserted into the groove 311 to hold the solar panel 5 (see Figures 2(a), 3, etc.). The wiring 8 of the photovoltaic panel 5 is passed through the internal space formed by the coping receiver 31 and the coping cover 32. A notch 311a is provided in the groove 311 of the cap board receiver 31 to avoid the terminal box 51 that is provided to protrude from one side of the solar panel 5. The wiring 8 is introduced into the cap board 3 from the terminal box 51 arranged in this notch 311a. The capping support 31 is also formed with a wiring hole 312 for leading the wiring 8 inside the capping 3 to the inside of the disposable support 6. The wiring hole 312 is provided at the connection point where the capping support 31 and the disposable support 6 are connected (see Figures 2(b) and 3).

[0012] Bottom Chord The lower chord 4 is attached so as to span the lower parts of the two pillars 2. The lower chord member 4 is fixed to the mounting member 23 at the bottom of the support 2 with bolts and nuts. The lower chord member 4 has a groove 41 extending longitudinally (left and right) on the outside for holding the solar panel 5. This groove 41 is formed to open upward, and the lower edge of the solar panel 5 is inserted into it to hold the solar panel 5 (see FIGS. 2(b) and (c)).

[0013] [Solar power generation panels] The solar panel 5 has a known configuration in which a large number of solar cells are arranged between two rectangular substrates, and in this embodiment, a terminal box 51 is attached to the upper edge so as to protrude. Wiring 8 is connected to the terminal box 51, and the generated power is taken out to the outside.

[0014] [Disposable support] Although the disposable support 6 appears to be a structure that supports the handrail 1 in the same way as the support 2, it is actually a wiring cover for leading the wiring 8 out of the handrail 1. Unlike the support 2, it does not have the function of supporting the handrail 1. The throw-away support 6 has a throw-away support body 61 and a throw-away support cover 62 (see FIG. 1, etc.). The upper end of the disposable support body 61 is fixed to the capping support 31 with a screw 611, and the lower part is fixed to the mounting member 42 of the lower chord 4 with a bolt and nut (see Figure 2(b) and Figure 5). The temporary support post cover 62 is engaged with the temporary support post main body 61, and the upper end thereof is fixed to the coping support 31 with a screw 621 (see FIG. 2(b) and FIG. 5). As a result, the auxiliary support 6 is detachably installed between the coping support 31 of the coping 3 and the floor 7. In this first embodiment, as will be described later, there is no need to attach or remove the throw-away support 6 when attaching or removing the solar panel 5, and a part of the throw-away support 6 (in this first embodiment, the throw-away support main body 61) can be firmly fixed with the mounting member 42 so that it overlaps the lower chord 4 when viewed from above. Furthermore, due to this mounting structure, a part of the throw-away support 6 (in this first embodiment, a part of the throw-away support main body 61) is located closer to the solar panel 5 than the lower chord 4, and the throw-away support 6 does not protrude significantly outside (inside) the lower chord 4, so the throw-away support 6 can be made to have a slim appearance, improving the design (see FIG. 2(c)). A temporary support base cover 63 is installed at the boundary between the temporary support 6 and the floor 7 to cover and conceal this boundary. This temporary support base cover 63 improves the design of the base of the temporary support 6 (see Figure 1). The base of the temporary support 6 is fitted onto a wiring conduit 71 protruding from the floor 7. The wiring conduit 71 is buried in the floor 7 and is a pipe for introducing wiring 8 into the building. The auxiliary support 6 is attached to one of the two sides of the photovoltaic panel 5 that blocks as little sunlight as possible. In this embodiment, since it is installed as a handrail for a balcony of a building, it is attached to the inner side surface of the photovoltaic panel 5. Therefore, the auxiliary support 6 is attached to the inner side of the coping support 31 and the lower chord 4.

[0015] [wiring] The wiring 8 runs from the terminal box 51 of the solar panel 5 through the inside of the fascia 3, is introduced into the disposable support 6 through the wiring hole 312, is led downward inside the disposable support 6, is introduced into the wiring conduit 71, passes through the wiring conduit 71 and is led into the building.

[0016] [Assembly process] FIG. 5 is a diagram showing an assembly process of the handrail 1 according to the first embodiment of the present invention. The process of assembling the solar panel 5 and the auxiliary support column cover 62 to the already installed support column 2, coping 3, lower chord member 4, and auxiliary support column body 61 will be described. FIG. 5( a ) shows the installation of a photovoltaic panel 5 . First, as shown in (1), insert the upper edge of the solar panel 5 into the groove 311 of the fascia support 31 from the outside of the handrail 1, and then, as shown in (2), insert the lower edge into the groove 41 of the lower chord 4. FIG. 5(b) shows the installation of the temporary support pole cover 62. First, as shown in (3), the disposable support cover 62 is engaged with the disposable support body 61. Next, as shown in (4), the upper end of the disposable support cover 62 is fixed to the capping support 31 with a screw 621. Finally, as shown in (5), the capping support 32 is engaged with the capping support 31, and as shown in (6), two disposable support base covers 63 are engaged and attached to the base of the disposable support 6 from both the inside and outside. After that, sealing or the like is performed to secure the solar panel 5. FIG. 5(c) shows the completed assembly state.

[0017] In the first embodiment, the solar power generation panel 5 is configured to be attachable and detachable from the outer side of the handrail 1, that is, from the side where the disposable support 6 is not installed. In this embodiment 1, the wiring 8 is stored inside the disposable support 6 rather than in the support 2, and when performing maintenance or replacement work on the solar power generation panel 5, the wiring 8 can be pulled out simply by removing the disposable support cover 62 of the disposable support 6, making it easy to perform maintenance or replacement work on the solar power generation panel 5. In addition, there is no need to remove or install the fascia cover 32 and the disposable support 6 when installing or removing the solar power generation panel 5, and the support 2 does not get in the way of installing or removing the solar power generation panel 5, so there is no need to consider the removal or installation of the solar power generation panel 5 when considering the structure of the disposable support 6 and the support 2, which allows for greater design freedom and improved design.

[0018] [Variations] FIG. 6 is a diagram showing the installation state of handrail 1 according to modified example 1 of the present invention, and FIG. 7 is a diagram showing the installation state of handrail 1 according to modified example 2 of the present invention. In the handrail 1 of embodiment 1, the wiring 8 of one solar power generation panel 5 is configured to be led inside a throw-away support 6 installed on the inner side of this solar power generation panel 5, but it is also possible to configure the wiring 8 of multiple solar power generation panels 5 to be grouped together and led inside a throw-away support 6 installed on the inner side of one of the multiple solar power generation panels 5. Figure 6 shows a configuration in which the wiring 8 of two solar panels 5 is combined and introduced inside a single disposable support 6, and Figure 7 shows a configuration in which the wiring 8 of three solar panels 5 is combined and introduced inside a single disposable support 6. The wiring 8 of the solar power generation panel 5 on which the disposable support 6 is not installed passes through the inside of the capping 3 from the terminal box 51 and is led to the terminal box 51 of the solar power generation panel 5 on which the disposable support 6 is installed, and the wiring 8 of the multiple solar power generation panels 5 is collected and introduced into the inside of the disposable support 6. Which of the multiple solar power generation panels 5 has the throw-away support 6 installed is a matter that can be designed as appropriate. For example, in the configuration shown in FIG. 6, instead of installing the throw-away support 6 on the left solar power generation panel 5, it is also possible to install the throw-away support 6 on the right solar power generation panel 5. In the configuration shown in FIG. 7, instead of installing the throw-away support 6 on the left solar power generation panel 5, it is also possible to install the throw-away support 6 on the central solar power generation panel 5, or install the throw-away support 6 on the right solar power generation panel 5. As in variants 1 and 2, the wiring 8 of multiple solar panels 5 can be grouped together and introduced inside a single disposable support 6, thereby reducing the number of disposable supports 6 in the entire handrail 1, allowing the wiring 8 to be efficiently guided to the bottom of the handrail 1 and improving the design.

[0019] [Embodiment 2] A second embodiment of the present invention will be described with reference to FIGS. FIG. 8 shows (a) a longitudinal cross-sectional view at the position of the support post 2, (b) a longitudinal cross-sectional view at the position of the auxiliary support post 6, and (c) a horizontal cross-sectional view of the handrail 1 of embodiment 2 of the present invention in an installed state. As will be described later, the second embodiment differs from the first embodiment in that the solar panel 5 is configured to be attachable and detachable from the inside of the handrail 1, that is, from the side where the disposable support 6 is installed. Therefore, the second embodiment differs from the first embodiment in the structure of the support 2 and the disposable support 6.

[0020] As in the first embodiment, the support pillar 2 is erected vertically on the floor 7. A support frame 21 for holding the side end of the solar power generation panel 5 is attached to the support pillar 2 so as to extend in the longitudinal (up-down) direction on the outer side of the support pillar 2. A groove 211 for holding the solar power generation panel 5 is formed in the support frame 21, and the side edge of the solar power generation panel 5 is inserted into the groove 211 to hold the solar power generation panel 5. As shown in Fig. 8(c), the distance between the two pillars 2 in this embodiment 2 is configured to be wider than the width (horizontal width) of the solar panel 5 in the direction in which the handrail 1 extends, which is different from embodiment 1. For this reason, the horizontal width of the pillars 2 in this embodiment 2 is formed to be narrower than the horizontal width of the pillars 2 in embodiment 1 (see also Fig. 2(c)).

[0021] As in the first embodiment, the temporary support 6 has a temporary support body 61 and a temporary support cover 62. The disposable support body 61 is similar to the first embodiment in that its upper end is attached to the coping support 31 with a screw 611. However, to make it easier to attach and detach the disposable support body 61, its lower part is fixed to the mounting part 43 of the lower chord 4 with a screw 612. As in the first embodiment, the temporary support post cover 62 is engaged with the temporary support post main body 61 and has its upper end fixed to the coping support 31 by a screw 621 . The auxiliary support 6 is fixed in a position where the entire support 6 protrudes outward (inward) from the lower chord 4 so that it can be easily attached and detached to and from the capping board holder 31 of the capping board 3 and the lower chord 4 (see Figure 8(c)). This allows the auxiliary support 6 to be detachably installed between the capping board holder 31 of the capping board 3 and the floor 7. Furthermore, when installing or removing the solar power generation panel 5, the auxiliary support 6 can be easily installed and detached, making maintenance and replacement work on the solar power generation panel 5 easy.

[0022] The process of assembling a solar panel 5 and a disposable support 6 to the already installed support 2, fascia 3, and lower chord 4 will be described. FIG. 9 is a diagram showing an assembly process of the handrail 1 according to the second embodiment of the present invention. FIG. 9( a ) shows the installation of a photovoltaic panel 5 . First, as shown in (1), insert the upper edge of the solar panel 5 into the groove 311 of the fascia support 31 from the inside of the handrail 1, and then, as shown in (2), insert the lower edge into the groove 41 of the lower chord 4. FIG. 9(b) shows the attachment of the temporary support body 61. First, as shown in (3), the disposable support body 61 is positioned at the installation location. Next, as shown in (4), the upper end of the disposable support body 61 is fixed to the coping support 31 with a screw 611. Finally, as shown in (5), the lower part of the disposable support body 61 is fixed to the lower chord 4 with a screw 612. FIG. 9(c) shows the installation of the temporary support pole cover 62. First, as shown in (6), the disposable support cover 62 is engaged with the disposable support body 61. Next, as shown in (7), the upper end of the disposable support cover 62 is fixed to the capping support 31 with a screw 621. Finally, as shown in (8), the capping support 32 is engaged with the capping support 31, and as shown in (9), two disposable support base covers 63 are engaged and attached to the base of the disposable support 6 from both the inside and outside. After that, sealing etc. are performed to secure the solar panel 5. FIG. 9(d) shows the completed assembly state.

[0023] In the second embodiment, the photovoltaic power generation panel 5 is configured to be attachable and detachable from the inside of the handrail 1, that is, from the side where the disposable support 6 is installed. Furthermore, in this embodiment 2, the wiring 8 is stored inside the disposable support 6 rather than the support 2, and when performing maintenance or replacement work on the solar power generation panel 5, the wiring 8 can be pulled out simply by removing the fascia cover 32 and the disposable support cover 62 of the disposable support 6, making it easy to perform maintenance or replacement work on the solar power generation panel 5. Furthermore, since the solar power generation panel 5 is attached and detached from the inside of the building's balcony, maintenance and replacement work on the solar power generation panel 5 can be easily performed regardless of where the handrail 1 is installed.

[0024] [Embodiment 3] A third embodiment of the present invention will be described with reference to FIG. FIG. 10 is a view showing the vicinity of the base of the disposable support 6 according to the third embodiment of the present invention. The third embodiment differs from the first and second embodiments in that the wiring 8 is configured to be led out from a wiring lead-out hole 61a formed in the base of the throwaway support body 61 to the outside. The wiring 8 led out to the outside is led to the power transmission destination by appropriate means.

[0025] In embodiments 1 to 3, the handrail 1 is installed on a balcony of a building, but it can also be installed on a balcony, terrace, deck, rooftop, outdoor park, plaza, etc., perimeter, walkway, etc. of a building. Regardless of the installation location, if the auxiliary support 6 is attached to the side of the solar panel 5 that receives the most sunlight when installed, it will block less sunlight. Furthermore, if the maintenance or replacement work for the solar power generation panel 5 does not involve working at a height, it is acceptable to either install it so that it can be attached and removed from the side where the disposable support 6 is not installed, as in embodiment 1, or to install it so that it can be attached and removed from the side where the disposable support 6 is installed, as in embodiment 2, but it is preferable to use a configuration like embodiment 1, which does not require the removal of the disposable support 6 and has a good design.

[0026] In the above embodiment 1, the wiring 8 is stored inside the disposable support 6 rather than the support 2, and when performing maintenance or replacement work on the solar power generation panel 5, the wiring 8 can be pulled out simply by removing the fascia cover 32 and the disposable support cover 62 of the disposable support 6, making it easy to perform maintenance or replacement work on the solar power generation panel 5. Furthermore, when installing or removing the solar power generation panel 5, there is no need to remove or install the disposable support 6, and the support 2 does not get in the way of installing or removing the solar power generation panel 5, so there is no need to consider the removal or installation of the solar power generation panel 5 when designing the structure of the disposable support 6 or support 2, which allows for greater design freedom and enables improved design.

[0027] In the above-mentioned embodiment 2, the wiring 8 is stored inside the disposable support 6, not inside the support 2, and when performing maintenance or replacement work on the solar power generation panel 5, the wiring 8 can be pulled out simply by removing the fascia cover 32 and the disposable support 6, making it easy to perform maintenance or replacement work on the solar power generation panel 5. Furthermore, since the solar power generation panel 5 can be attached and removed from the inside of the building's balcony, maintenance and replacement work on the solar power generation panel 5 can be easily performed regardless of where the handrail 1 is installed.

[0028] Above, the first embodiment, the first variation, the second variation, the second embodiment, and the third embodiment of the present invention have been described in detail with reference to the drawings. However, the specific configurations are not limited to these embodiments and variations, and the present invention also includes design changes and the like within the scope of the present invention that do not deviate from the gist of the present invention. Furthermore, the above-mentioned embodiment 1, variant 1, variant 2, embodiment 2, and embodiment 3 can be combined by reusing each other's technologies, as long as there are no particular contradictions or problems in their purposes, configurations, etc. [Explanation of symbols]
