[0003] [Patent Document 1] JP 2019-205235 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in order to install the power supply pole, it is necessary to dig holes for installing the power supply pole and pour concrete, which increases the time and cost required for the installation work of the power supply pole.

[0005] In view of this situation, a main object of the present invention is to provide a power feed pole, a power feed pole installation structure, and a power feed pole installation method that can reduce the effort and cost of installation work. [Means for solving the problem]

[0006] The first characteristic configuration of the present invention is a pole part that can be installed in an upright state on the ground and has a pole outlet attachment part to which a pole outlet can be attached and a power line connected to the pole outlet can be wired inside; a box section that is interposed between a side surface of the pole section and a target part on a building side and that can fixedly connect the pole section to the target part, and that can have a power line wired therein; The pole portion has a communication portion that communicates between the internal space of the pole portion and the internal space of the box portion so that a power line can be inserted therethrough.

[0007] According to this configuration, the power line that is wired between the internal space of the box and the internal space of the pole can be connected to the pole outlet fixed to the pole outlet mounting part of the pole. Then, by fixing and connecting the box to the target part on the building and the pole with the pole standing on the ground, the power supply pole can be installed using the target part on the building. This simplifies the fixing of the pole to the ground, and for example, it is possible to eliminate or reduce the amount of holes or concrete required to fix the pole to the ground, thereby reducing the effort and cost of the installation work.

[0008] A second characteristic configuration of the present invention is that the box portion has a first box hole through which the power line derived from the fixing target portion can be introduced into the inside of the box portion, and a building side fixing portion that can be fixed in a state in which the first box hole faces the fixing target portion.

[0009] According to this configuration, the power line leading out from the part to be fixed on the building side can be introduced into the box part through the first box hole, while the building side fixed part from which the power line is led out can be covered by the building side fixed part of the box part. Therefore, the power line leading out from the part to be fixed on the building side can be wired to the pole outlet attachment part through the box hole of the box part, the internal space of the box part, the communication part, and the internal space of the pole part without being exposed to the outside.

[0010] A third characteristic configuration of the present invention is that the box portion has a second box hole at a portion exposed to the outside when the pole portion is fixedly connected to the target portion, through which a power line extending from the building side can be introduced.

[0011] According to this configuration, when the power line is led out from a part other than the part to be fixed on the building side, the power line can be led into the internal space of the box part through the second box hole, and can be connected to the pole outlet fixed to the pole outlet mounting part of the pole part through the internal space of the box part and the internal space of the pole part. Therefore, the pole outlet can be installed using the power line led out from a part other than the part to be fixed. Furthermore, when the box part has the above-mentioned first box hole in addition to the second box hole, the power line led into the box part from the first box hole can be led out to the outside from the second box hole when the power line led out from the part to be fixed on the building side is used for a purpose other than connecting to the pole outlet.

[0012] A fourth characteristic configuration of the present invention is that the box portion is provided with a box outlet mounting portion capable of mounting a box outlet at a portion exposed to the outside when the pole portion is fixedly connected to the target portion.

[0013] For example, if an outlet is attached to the fixed part on the building side to which the box part is fixedly connected, it is necessary to remove the outlet from the fixed part, and it is conceivable that removing the outlet may cause inconvenience. However, with this configuration, the box outlet can be attached to the box outlet mounting part, thereby eliminating the inconvenience caused by the outlet being removed from the fixed part.

[0014] A fifth characteristic configuration of the present invention is that the pole portion comprises a hollow cylindrical pole body portion and a base portion disposed at the lower end of the pole body portion and having an outer edge of a bottom surface portion larger than the outer edge of the pole body portion.

[0015] According to this configuration, the outer edge of the bottom surface of the base portion is larger than the outer edge of the pole portion, so that the ground contact area of ​​the pole portion when the power supply pole is installed can be enlarged. This allows the pole portion to be stably placed on the ground, which can further reduce the labor and cost of installation work. Although it is preferable to simply place the pole portion on the ground, the pole portion may be fixed to the ground using adhesives, screws, etc. as necessary. In this case, the ground contact area of ​​the pole portion is enlarged by the base portion, so that fixing using adhesives, screws, etc. can be easily performed.

[0016] A sixth characteristic feature of the present invention is that a fixed connecting member is provided for fixedly connecting the pole portion to the fixed target portion at a height shifted in the up-down direction with respect to the box portion.

[0017] According to this configuration, the box portion and the fixed connecting member enable the pole portion to be fixedly connected to the target portion on the building at multiple points in the vertical direction, thereby enabling the power supply pole to be installed stably.

[0018] A seventh characteristic configuration of the present invention is a structure for installing a power supply pole, in which a pole portion having a pole outlet attachment portion and capable of wiring a power line therein is installed in an upright state on the ground away from a fixed target portion on the building side, A side portion of the pole portion is fixedly connected to the fixed target portion via a box portion having a box hole through which a power line can be introduced and through which a power line can be wired, a communication section that communicates between the internal space of the pole section and the internal space of the box section so that a power line can be inserted therethrough; The power line is wired from the building side to the pole outlet mounting portion of the pole portion through the box hole of the box portion, the internal space of the box portion, the communication portion, and the internal space of the pole portion.

[0019] According to this configuration, the power line on the building side can be connected to the pole outlet attached to the pole outlet attachment part through the box hole of the box part, the internal space of the box part, the communication part, and the internal space of the pole part. Then, by fixing and connecting the box part to the fixing target part on the building side and the pole part while the pole part is standing on the ground, the power supply pole can be installed using the fixing target part on the building side. Therefore, it is possible to simplify the fixing of the pole part to the ground, for example, to eliminate or reduce holes and concrete for fixing the pole part to the ground, and reduce the effort and cost of the installation work.

[0020] The eighth characteristic configuration of the present invention is a method for installing a power supply pole, comprising the steps of: removing an existing outlet on an exterior wall surface of a building, the existing outlet being installed as a fixed target portion on the building side, while leaving an existing power line; A pole portion having a pole outlet attachment portion and capable of wiring a power line therein is installed in an upright state on the ground spaced apart from the fixing target portion; A side portion of the pole portion is fixedly connected to the fixed target portion via a box portion having a box hole through which a power line can be introduced and through which a power line can be wired; The feature is that a power line is wired from an existing power line of the fixed portion on the building side to the pole outlet mounting portion of the pole portion through the box hole of the box portion, the internal space of the box portion, a communication portion that communicates the internal space of the pole portion with the internal space of the box portion, and the internal space of the pole portion.

[0021] According to this configuration, the existing power line remaining in the target attachment portion can be connected to the pole outlet attached to the pole outlet attachment portion through the box hole of the box portion, the internal space of the box portion, the communication portion, and the internal space of the pole portion. Then, by fixing and connecting the box portion to the target attachment portion on the building side and the pole portion while the pole portion is standing on the ground, the power supply pole can be installed using the target attachment portion on the building side. Therefore, the fixing of the pole portion to the ground can be simplified, and for example, holes and concrete for fixing the pole portion to the ground can be eliminated or reduced, thereby reducing the effort and cost of the installation work. Moreover, the power supply pole can be installed by effectively utilizing the existing power line without wiring a new power line. [Brief description of the drawings]

However, when the box portion 8 is fixedly connected to a relatively high position such as the middle or upper portion of the pole portion 4 in the vertical direction Z, the fixed connecting member 12 may be fixedly connected to the pole portion 4 below the box portion 8. In this embodiment, only one fixed connecting member 12 is provided, but two or more fixed connecting members 12 may be provided. In this case, the fixed connecting member 12 may be provided not only on one of the upper and lower sides of the box portion 8, but also on both the upper and lower sides of the box portion 8.

[0042] As shown in Figures 2 and 3, the installation structure of the power supply pole 1 is such that the pole section 4, which has a pole outlet mounting section 15 and through which a power line 10 can be wired, is installed in an upright position on the ground G away from the fixed target portion 7 on the building 6 side. As shown in FIG. 5, the installation structure of the power supply pole 1 is such that the side portion of the pole portion 4 is fixedly connected to the fixed target portion 7 via a box portion 8 having box holes 36B, 44B through which the power line 10 can be introduced and through which the power line 10 can be wired, and a communication portion 11 is provided that communicates between the internal space of the pole portion 4 and the internal space of the box portion 8 so that the power line 10 can be inserted, and the power line 10 is wired from the building 6 side to the pole outlet mounting portion 15 of the pole portion 4 through the box holes 36B, 44B of the box portion 8, the internal space of the box portion 8, the communication portion 11, and the internal space of the pole portion 4.

[0043] In the installation structure shown in Figure 5, the first box hole 36B is utilized to introduce the power line 10 extending from the fixed target portion 7 into the box portion 8 through the first box hole 36B, and the introduced power line 10 is then connected to the pole outlet 14 attached to the pole outlet mounting portion 15 through the internal space of the box portion 8, the communicating portion 11, and the internal space of the pole portion 4. In addition, in the installation structure shown in Figure 8, the second box hole 44B is utilized to introduce the power line 10 (second power line 10B) led out from outside the fixed target portion 7 into the box portion 8 from the second box hole 44B, and the introduced power line 10 is connected to the pole outlet 14 attached to the pole outlet mounting portion 15 through the internal space of the box portion 8, the communicating portion 11, and the internal space of the pole portion 4.

[0044] Next, a method for installing the power supply pole 1 will be described. The method of installing the power supply pole 1 is to remove the existing outlet 40 (for example, an outdoor outlet for general use or for charging electric vehicles) on the exterior wall surface of the building 6 while leaving the existing power line 10 in place, with the existing outlet 40 being set as the fixed target part 7 on the building 6 side (removing the outlet 40), install the pole part 4 having the pole outlet attachment part 15 and capable of wiring the power line 10 inside in an upright state on the ground G separated from the fixed target part 7 (installing the pole part 4), and attach the side part of the pole part 4 to the power line 10. This includes fixedly connecting to the fixed target part 7 via a box part 8 having a first box hole 36B that can be introduced inside and into which the power line 10 can be wired (fixedly connecting the pole part 4), and wiring the power line 10 from the existing power line 10 of the fixed target part 7 on the building 6 side to the pole outlet mounting part 15 of the pole part 4 through the box holes 36B, 44B of the box part 8, the internal space of the box part 8, the communication part 11 that communicates between the internal space of the pole part 4 and the internal space of the box part 8, and the internal space of the pole part 4 (wiring the power line 10).

[0045] For example, as shown in FIG. 6, the power supply pole installation method includes a receptacle removal step S1, a box section connection step S2, a pole section installation step S3, a power line wiring step S4, and a receptacle installation step S5. The outlet removal step S1 is a step of "removing the outlet 40" as described above, and is a step of removing the existing outlet 40 from the target fixed portion 7 while leaving the existing power line 10 in place.
