[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates are set and referred to as appropriate. The XY plane of the XYZ coordinates is a plane parallel to the roof surface R on which the mounting base 1 is installed. The Z-axis direction is a direction parallel to the height direction H from the roof surface R. In addition, in this embodiment, the eaves-ridge direction, which is the direction from the ridge of the building to the eaves, is the same direction as the X-axis direction.

[0019] 1 and 2, the mount 1 is attached to, for example, a roof surface R of a building, and is used to support a solar panel P as an installation target to be installed on the roof surface R. In this embodiment, the building to which the mount 1 is attached is a house having a roof with eaves and a ridge. The mount 1 according to the embodiment includes a pedestal 10, a mount base 20, a fixing unit 30, a receiving member 40, and a first fastener 50.

[0020] The fixing unit 30 is fixed to the receiving member 40 by the first fastener 50, and fixes the solar panel P. The fixing unit 30 includes an installation target arrangement member 31, a fixing member 32, a cover 37, a fixing member receiving member 38, and a second fastener 39. The fixing unit 30 may not include the cover 37, and the cover 37 may be replaced with the fixing member receiving member 38. Each component of the fixing unit 30 is formed of, for example, metal. However, this is not limited to this. Each component of the fixing unit 30 may be formed of a material other than metal. For example, each component of the fixing unit 30 may be formed of a highly rigid material such as resin or ceramic. Furthermore, some of the components of the fixing unit 30 may be formed of different materials. However, each component of the fixing unit 30 is preferably formed of metal, and more preferably, all of the components of the fixing unit 30 are preferably formed of the same metal material.

[0021] In this embodiment, the installation target placement member 31 is a horizontal cross-piece extending in the Y-axis direction. The installation target placement member 31 is formed so that its XZ cross-section has a rectangular, square-tube shape with the Z-axis direction as its longitudinal direction. The installation target placement member 31 is formed, for example, by extruding metal. Specifically, the installation target placement member 31 is formed, for example, by extruding aluminum. On the top surface on the +Z side of this installation target placement member 31, a fixing member attachment groove is formed along the Y-axis direction, which is perpendicular to the eaves-ridge direction, which is the direction from the ridge to the eaves of the building. Note that, in this embodiment, the installation target placement member 31 is a horizontal cross-piece extending in a direction perpendicular to the eaves-ridge direction. However, this is not limited to this. The installation target placement member 31 may also be a cross-piece other than a horizontal cross-piece. For example, the installation target placement member 31 may be a vertical cross-piece extending in the same direction as the eaves-ridge direction. Furthermore, the installation target arrangement member 31 may be a crosspiece other than a horizontal crosspiece or a vertical crosspiece extending in a direction intersecting the eaves-ridge direction.

[0022] The upper surface on the +Z side of the installation target arrangement member 31 is the surface on which the solar panel P is arranged. This upper surface on the +Z side is formed in a plane parallel to the YZ plane so that the solar panel P can be easily arranged thereon.

[0023] The fixing members 32 are metal fittings that sandwich the solar panel P arranged on the upper surface of the installation target arrangement member 31 and are fixed to the installation target arrangement member 31. In this embodiment, three fixing members 32 are provided, and the three fixing members 32 fix two solar panels P. The fixing members 32 have side wall portions 32-1 and 32-2, a connecting plate portion 32-3, and extension portions 32-4 and 32-5.

[0024] The side walls 32-1 and 32-2 are formed in the shape of plates parallel to the YZ plane.

[0025] The connecting plate portion 32-3 is formed in the shape of a plate parallel to the XY plane. This connecting plate portion 32-3 connects the side wall portions 32-1 and 32-2. A hole into which the second fastener 39 is inserted is formed in the connecting plate portion 32-3.

[0026] The extension portion 32-4 extends from the upper end (the end on the +Z side) of the side wall portion 32-1. The extension portion 32-4 presses any one of the solar panel P, the cover 37, and the fixing member receiving member 38 against the installation target arrangement member 31. A locked portion 32-4a is formed on the lower surface on the -Z side of the extension portion 32-4.

[0027] The extension portion 32-5 extends from the upper end (the end on the +Z side) of the side wall portion 32-2 in the direction opposite to the extension direction of the extension portion 32-4. The extension portion 32-5 presses any one of the solar panel P, the cover 37, and the fixing member receiving member 38 against the installation target arrangement member 31. Unlike the extension portion 32-4, no locked portion is formed on the underside of the extension portion 32-5 on the -Z side.

[0028] The cover 37 covers the end of the installation target arrangement member 31 on the +Y side. The cover 37 is made of a conductive material. The cover 37 is formed, for example, by extruding metal. Specifically, the cover 37 is formed, for example, by extruding aluminum, and then the surface is anodized black to cover the silver color that is the color of the aluminum itself. The cover 37 has a cover main body 37-1 and a spacer 37-2.

[0029] The second fastener 39 sandwiches the solar panel P between the installation target arrangement member 31 and the fixing member 32, and fastens the installation target arrangement member 31 and the fixing member 32 together.

[0030] The receiving member 40 receives the fixing unit 30 from below. The receiving member 40 is formed by, for example, extruding metal. Specifically, the receiving member 40 is formed by, for example, extruding aluminum.

[0031] The first fastener 50 has a bolt 51 and a nut 52. The bolt 51 is, for example, a bolt or a screw. In this embodiment, the bolt 51 of the first fastener 50 is threaded into the nut 52. However, this is not limited to this. For example, the hole in the receiving member 40 may be a screw hole, and the bolt 51 may be threaded into this hole. In this case, the nut 52 can be omitted, and the first fastener 50 is composed of only the bolt 51.

[0032] As shown in FIGS. 3(A) and 3(B), the base 10 includes a rectangular sheet made of butyl rubber, and has a plurality of circular mounting holes 11 and a plurality of grooves 12 extending in the Y-axis direction formed on its surface. The grooves 12 have a non-slip effect. Note that the shape of the base 10 shown in the figures is an example and is not limited to this. Furthermore, the material of the base 10 is not limited to butyl rubber and may be other materials. A base mounting fastener 60 shown in FIG. 4 is inserted into the mounting hole 11.

[0033] As shown in Figures 4 and 5(A), the base 20 of the mount is a T-shaped angle bracket whose XZ cross section is T-shaped and which supports the receiving member 40 near the upper end of the T-shape. The base 20 of the mount includes a bottom plate portion 21, an upright plate portion 22, a height adjustment groove 23 (receiving member mounting portion), a protrusion 24, and a mounting hole 25. A pedestal 10 is attached to the back surface of the bottom plate portion 21 of the base 20 of the mount, and the base 20 is attached to the roof surface R of the building via the pedestal 10.

[0034] The bottom plate portion 21 is a rectangular plate-like member, and has a plurality of grooves 26 formed on the rear surface thereof, extending in the Y-axis direction. The plurality of grooves 26 have a non-slip effect. As shown in FIG. 5(B), the length L1 of the bottom plate portion 21 in the X-axis direction is longer than the length L2 in the Y-axis direction. The bottom plate portion 21 also has a first region 21a and a second region 21b. One or more mounting holes 25 are formed in each of the first region 21a and the second region 21b. In this example, three mounting holes 25 are formed in each of the first region 21a and the second region 21b.

[0035] The standing plate portion 22 is a plate-like member erected between the first region 21a and the second region 21b of the bottom plate portion 21. The bottom plate portion 21 and the standing plate portion 22 are integrally formed by, for example, extruding metal. Specifically, the bottom plate portion 21 and the standing plate portion 22 are formed by, for example, extruding aluminum.

[0036] As shown in FIG. 4, the height direction adjustment groove 23 (receiving member mounting portion) is a groove that is formed in the standing plate portion 22 and extends long in the height direction H. A first fastener 50 is inserted into the height direction adjustment groove 23. The height direction adjustment groove 23 is used to adjust the position of the receiving member 40 in the height direction H.

[0037] The protrusion 24 protrudes in the +X direction from the upper end (end on the +Z side) of the base 20 of the gantry. The head of a bolt of the first fastener 50 is caught on the protrusion 24, thereby preventing the first fastener 50 from coming off the height-direction adjustment groove 23 upward (in the +Z direction). In the present embodiment, the protrusion 24 protrudes in the +X direction from the upper end (end on the +Z side) of the base 20 of the gantry. However, this is not limited to this. The protrusion 24 may protrude in the -X direction, which is opposite to the +X direction, from the upper end (end on the +Z side) of the base 20 of the gantry. However, if the protrusion 24 protrudes in the -X direction, there is a risk of interference with the receiving member 40. For this reason, it is preferable that the protrusion 24 protrude in the +X direction from the upper end (end on the +Z side) of the base 20 of the gantry.

[0038] The mounting holes 25 include elongated holes extending in the X-axis direction. Base mounting fasteners 60 are inserted into the mounting holes 25. This allows the base 20 of the mount to be temporarily fixed with the base mounting fasteners 60 and the position to be adjusted in a first direction D1 parallel to the X-axis direction.

[0039] A method for constructing the mount 1 configured as described above will be described with reference to the drawings.

[0040] When installing the mounting frame 1 and the solar panel P on the roof surface R of a building, a worker installing the mounting frame 1 on the roof surface R first places the base 10 on the roof surface R, as shown in Fig. 6. The base 10 includes a sheet made of butyl rubber.

[0041] Next, the base 20 of the mounting frame is attached to the roof surface R. In detail, first, as shown in FIG. 7, the base 20 of the mounting frame is placed on the roof surface R, and then, as shown in FIG. 8, the base 20 of the mounting frame is temporarily fixed to the roof surface R using the base attachment fasteners 60. At this time, the base 20 of the mounting frame is shifted in the first direction D1 to adjust the installation position to the eaves side or the ridge side. After adjustment, the base attachment fasteners 60 are tightened to fix the base 20 of the mounting frame to the roof surface R. The number of base attachment fasteners 60 is determined according to the required fixing strength. For example, when fixing to rafters, two fasteners are used. When fixing to sheathing boards, five fasteners are used.

[0042] Next, as shown in FIG. 4, the first fastener 50 is used to temporarily fasten the receiving member 40 to the base 20 of the stand.

[0043] Next, the installation target arrangement member 31 without the solar panel P attached thereto is fitted into the receiving member 40 from the +Z side (upper side).

[0044] Next, the height level from the roof surface R to the top end of the installation target arrangement member 31 is adjusted to the desired height level by the worker. Then, the worker uses the first fastener 50 to fix the receiving member 40 to the base 20 of the rack.

[0045] 1, the solar panel P, the cover 37 having the spacers 37-2, and the fixing member receiving member 38 are placed on the top surface of the installation target arrangement member 31. Then, the worker uses a plurality of fixing members 32 to fix the solar panel P, the cover 37, and the fixing member receiving member 38 to the installation target arrangement member 31. At this time, the positions of the plurality of fixing members 32 can be adjusted along the fixing member attachment grooves 31a, so that the solar panel P can be firmly fixed.

[0046] As a result of the above, the work of installing the mounting frame 1 and the solar panel P on the roof surface R of the building is completed, as shown in FIGS.

[0047] As described above, the mount 1 and the mount base 20 according to this embodiment have T-shaped cross sections of the bottom plate portion 21 and the upright plate portion 22, ensuring sufficient fixing strength with small fixing members. Furthermore, the mount base 20 has mounting holes 25 including elongated holes extending in the X-axis direction, allowing the mount base 20 to be shifted in the first direction D1 to adjust the installation position toward the eaves or ridge. Furthermore, the upright plate portion 22 is erected between the first region 21a and the second region 21b of the bottom plate portion 21, and one or more mounting holes 25 are formed in each of the first region 21a and the second region 21b. This allows the mount base 20 to be stably fixed to the roof surface R of the building. The upright plate portion 22 has a height adjustment groove 23 extending in the height direction, allowing the position of the receiving member 40 in the height direction H to be adjusted. Furthermore, a plurality of grooves 26 are formed on the rear surface of the bottom plate portion 21, so that the base 20 of the mount can be fixed so as not to shift relative to the roof surface R of the building.

[0048] (Variation) In the above-described embodiment, an example has been described in which the base 20 of the mount is shifted in the first direction D1 to adjust the installation position toward the eaves side or the ridge side. In this case, as shown in Fig. 9 , when the installation position of the base 20 of the mount is adjusted toward the ridge side with respect to the mount 10, the ridge-side end 10a of the mount 10 is located at the same position as the ridge-side end 21c of the mount base 20, or is located closer to the ridge than the ridge-side end 21c of the mount base 20. This is achieved by setting the size and shape of the mount 10 and the position of the mounting hole 11 of the mount 10 so that, when the positions of the mounting holes 11 of the mount 10 and the ridge-side positions of the mounting holes 25 of the mount base 20 are aligned, the ridge-side end 10a of the mount 10 is located at the same position as the ridge-side end 21c of the mount base 20, or is located closer to the ridge than the ridge-side end 21c of the mount base 20. This prevents rainwater from accumulating between one end 21c on the ridge side of the base 20 of the mount and the roof surface R of the building. Furthermore, as shown in Fig. 10, when the base 20 of the mount is adjusted to the eaves side, the other end 21d on the eaves side of the base 20 of the mount should be positioned closer to the eaves side than the other end 10b on the eaves side of the pedestal 10. This allows the size of the pedestal 10 to be reduced, thereby reducing costs.

[0049] In the mounting base 20 of the above embodiment, an example has been described in which the pedestal 10 has a plurality of circular mounting holes 11, but the shape of the mounting holes 11 formed in the pedestal 10 is not particularly limited. For example, as shown in Fig. 11, the pedestal 10 may have a mounting hole 11 that includes an elongated hole extending in the X-axis direction. In this way, the mounting base 20 can be shifted in the first direction D1 to easily adjust the installation position to the eaves side or the ridge side.

[0050] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and do not limit the scope of the present invention. [Explanation of symbols]
