[0016] 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 rack 1 is installed. The Z-axis direction is parallel to the height direction H from the roof surface R. In this embodiment, the ridge direction, which is the direction from the ridge of the building to the eaves, is the same direction as the X-axis direction.

[0017] 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 fixing unit 30, a receiving member 40, a base unit 50, and a first fastener 60.

[0018] The fixing unit 30 is fixed to the receiving member 40 by the first fastener 60, and fixes the solar panel P. The fixing unit 30 has an installation target arrangement member 31, a fixing member 32, a cover 37, a receiving member for the fixing member 38, and a second fastener 39. 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 a material with high rigidity such as resin or ceramic. In addition, 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.

[0019] In this embodiment, the installation target arranging member 31 is a horizontal bar extending in the Y-axis direction. The installation target arranging member 31 is formed so that its XZ cross section has a rectangular square tube shape with the Z-axis direction as the longitudinal direction. The installation target arranging member 31 is formed, for example, by extruding metal. Specifically, the installation target arranging member 31 is formed, for example, by extruding aluminum. On the upper surface on the +Z side of the installation target arranging member 31, a groove for attaching a fixing member is formed along the Y-axis direction 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 arranging member 31 is a horizontal bar extending in a direction perpendicular to the eaves-ridge direction. However, this is not limited to this. The installation target arranging member 31 may be a bar other than a horizontal bar. For example, the installation target arranging member 31 may be a vertical bar extending in the same direction as the eaves-ridge direction. Furthermore, the installation target arrangement member 31 may be a batten other than a horizontal batten or a vertical batten extending in a direction intersecting the eaves-ridge direction.

[0020] 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 as a surface parallel to the YZ plane so that the solar panel P can be easily arranged thereon.

[0021] 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 the present 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.

[0022] The side walls 32-1 and 32-2 are formed in the shape of a plate parallel to the YZ plane.

[0023] The connecting plate portion 32-3 is formed in a plate shape parallel to the XY plane. The connecting plate portion 32-3 connects the side wall portions 32-1 and 32-2. The connecting plate portion 32-3 has a hole into which the second fastener 39 is inserted.

[0024] 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.

[0025] The extension portion 32-5 extends from the upper end (the end on the +Z side) of the side wall portion 32-2 in a 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 lower surface on the -Z side of the extension portion 32-5.

[0026] 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 a metal. Specifically, the cover 37 is formed, for example, by extruding aluminum, and then the surface is subjected to a black color anodizing treatment 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.

[0027] The second fastener 39 sandwiches the solar panel P between the installation target placement member 31 and the fixing member 32, and fastens the installation target placement member 31 and the fixing member 32 together.

[0028] The receiving member 40 receives the fixed unit 30 from below. The receiving member 40 is formed, for example, by extruding metal. Specifically, the receiving member 40 is formed, for example, by extruding aluminum.

[0029] The support member 20 is an L-shaped angle metal fitting whose XZ cross section is formed in an L shape and supports the receiving member 40 near the upper end of the L shape. The support member 20 is fixed to a slide metal fitting S of the base unit 50. The support member 20 is provided with a height direction adjustment groove 21 (receiving member mounting portion) and a protrusion 23.

[0030] The height direction adjustment groove 21 (receiving member attachment portion) is a groove that extends long in the height direction H. The first fastener 60 is inserted into the height direction adjustment groove 21. The height direction adjustment groove 21 is used to adjust the position of the receiving member 40 in the height direction H.

[0031] The protrusion 23 protrudes in the +X direction from the upper end (end on the +Z side) of the support member 20. The bolt head of the first fastener 60 is caught in the protrusion 23, which prevents the first fastener 60 from coming off the height direction adjustment groove 21 upward (in the +Z direction). In the present embodiment, the protrusion 23 protrudes in the +X direction from the upper end (end on the +Z side) of the support member 20. However, this is not limited to this. The protrusion 23 may protrude in the -X direction, which is opposite to the +X direction, from the upper end (end on the +Z side) of the support member 20. However, if the protrusion 23 protrudes in the -X direction, there is a risk that it will interfere with the receiving member 40 attached to the support member 20. For this reason, it is preferable that the protrusion 23 protrudes in the +X direction from the upper end (end on the +Z side) of the support member 20.

[0032] The fastener B1 for attaching the support member is composed of, for example, a bolt or a screw. The fastener B1 for attaching the support member is screwed into a screw hole of the slide fitting S. The fastener B1 for attaching the support member is used to attach the support member 20 to the slide fitting S.

[0033] The first fastener 60 has a bolt 61 and a nut 62. The bolt 61 is, for example, a bolt or a screw. In this embodiment, the bolt 61 of the first fastener 60 is screwed into the nut 62. However, this is not limited to this. For example, the hole of the receiving member 40 may be a screw hole, and the bolt 61 may be screwed into this hole. In this case, the nut 62 can be omitted, and the first fastener 60 is composed of only the bolt 61.

[0034] The base unit 50 fixes the receiving member 40 so as to be adjustable in the height direction H from the roof surface R, and supports the fixed unit 30 via the receiving member 40. The base unit 50 has a base 10 of the rack, a slide fitting S (slide member), a support member 20, and a fastener B1 for attaching the support member.

[0035] The base 10 of the mount is formed, for example, from a metal, specifically, for example, by die casting using a mold. As shown in FIG. 3, the base 10 of the mount includes a base body 11, a first mounting bracket 12, and a second mounting bracket 13.

[0036] The base body 11 comprises a bottom plate portion 11B fixed to the roof surface R shown in Figure 1, a pair of side wall portions 11R and 11L erected on the bottom plate portion 11B, and a wall portion 14 formed at one end of the bottom plate portion 11B.

[0037] A pair of grooves 15R, 15L into which a part of a slide fitting S used to fix the support member 20 shown in FIG. 1 is fitted are formed on the opposing surfaces of the pair of side walls 11R, 11L.

[0038] The grooves 15R, 15L are formed to extend along the first direction D1 (ridge direction). Slide regulating portions 16R, 16L are formed in the grooves 15R, 15L. In the present embodiment, two slide regulating portions 16R, 16L are formed in the grooves 15R, 15L, respectively. However, this is not limited to this. The slide regulating portions 16R, 16L may be formed in one of the grooves 15R, 15L.

[0039] The slide restriction portions 16R, 16L are formed to restrict sliding of the slide fitting S in the first direction D1 relative to the base 10 of the stand shown in Fig. 1. In this embodiment, the slide restriction portions 16R, 16L restrict sliding of the slide fitting S in the +X direction relative to the base 10 of the stand shown in Fig. 1.

[0040] The wall portion 14 is provided at an end of the base body 11 near the ridge (near the -X side) with a gap between it and the pair of side walls 11R and 11L, and is formed to protrude upward (in the +Z direction) with respect to the XY plane. The wall portion 14 is formed integrally with the base body 11 by casting. The wall portion 14 is used, for example, so that rainwater flowing from the ridge side flows to the left and right. As shown in FIG. 4, the wall portion 14 is formed with a first inclined surface 14A, a second inclined surface 14B, and a protruding surface 14C. The first inclined surface 14A is formed to be inclined with respect to the first direction D1. The second inclined surface 14B is an inclined surface different from the first inclined surface 14A. The second inclined surface 14B is formed to be inclined with respect to the first direction D1. The protruding surface 14C is provided between the first inclined surface 14A and the second inclined surface 14B. The protruding surface 14C is formed to protrude in the ridge direction (in the -X direction). In the present embodiment, the protruding surface 14C is formed as a curved surface.

[0041] The first mounting bracket 12 is for fixing the base body 11 to the roof surface R shown in FIG. 1, and includes a pressing portion 12A for pressing the bottom plate portion 11B, and fixing portions 12B and 12C formed at both ends and fixed to the roof surface R. The pressing portion 12A is provided in the gap 11C between the wall portion 14 and the pair of side walls 11R and 11L, and is disposed on the upper surface of the bottom plate portion 11B. The fixing portions 12B and 12C are provided with a step corresponding to the thickness of the base body 11 relative to the pressing portion 12A. The fixing portions 12B and 12C are provided with screw holes through which the base mounting fastener B2 shown in FIG. 3 is inserted. The length of the first mounting bracket 12 in the Y direction is greater than the length of the base body 11 in the Y direction.

[0042] The second mounting bracket 13 is for fixing the base body 11 to the roof surface R, and has a pressing portion 13A that presses the bottom plate portion 11B, and fixing portions 13B, 13C that are formed at both ends and fixed to the roof surface R. As shown in Figs. 5 and 6, the pressing portion 13A is provided on the upper surface of the pressing portion 13A, and is disposed in a slit 11D provided between the base body 11 and the pair of side wall portions 11R, 11L. The fixing portions 13B, 13C are provided with screw holes through which the base mounting fastener B2 shown in Fig. 3 is inserted. The length of the second mounting bracket 13 in the Y direction is greater than the length of the base body 11 in the Y direction.

[0043] The base 10 of the stand is used with a sheet 90 made of, for example, butyl rubber attached to its back surface. The shape of the sheet 90 made of butyl rubber shown in Fig. 1 is merely an example and is not limited to this. The material of the sheet 90 is not limited to butyl rubber and may be other than butyl rubber.

[0044] The base 10 of the stand configured as described above is manufactured by, for example, casting in which at least two dies are opened in the up-down direction (+Z direction and -Z direction) to integrally form the base body 11 and the wall portion 14. However, the present invention is not limited to this, and any manufacturing method other than casting may be used as long as it can integrally form the base body 11 and the wall portion 14. Furthermore, the base 10 of the stand is preferably manufactured by die casting, which is a type of casting. However, the present invention is not limited to this. The base 10 of the stand may be manufactured by casting other than die casting, such as a sand mold, a plaster mold, a resin mold, or lost wax.

[0045] The sliding fitting S shown in Fig. 1 is fitted into grooves 15R and 15L of the base 10 of the mount shown in Fig. 3 so as to be slidable in a first direction D1. The sliding fitting S is attached to the base 10 of the mount at any position in the first direction D1 to position the solar panel P in the first direction D1. The sliding fitting S is made of, for example, metal, and more specifically, is made of the same metal material as the base 10 of the mount. A screw hole is formed in this sliding fitting S. This screw hole is formed to penetrate in the Z-axis direction, a support member mounting fastener B1 is screwed into it, and the inner peripheral surface is formed into a female thread surface.

[0046] A method for constructing the mounting base 1 configured as above will be described with reference to the drawings.

[0047] When installing the mounting stand 1 and the solar panel P shown in Fig. 1 on the roof surface R of a building, a worker installing the mounting stand 1 on the roof surface R first attaches the base 10 of the mounting stand shown in Fig. 3 to the roof surface R. In detail, first, the base main body 11 is placed on the roof surface R, and the base main body 11 is fixed to the roof surface R by the base installation fasteners B2.

[0048] Next, as shown in Figures 5 and 6, pressing portion 12A of first mounting bracket 12 is placed on the upper surface of bottom plate portion 11B, between wall portion 14 and pair of side walls 11R, 11L, and gap 11C. Also, pressing portion 13A of second mounting bracket 13 is placed on the upper surface of bottom plate portion 11B, in slit 11D provided between base main body 11 and pair of side walls 11R, 11L. This completes assembly of mounting base 10, as shown in Figure 7.

[0049] Next, as shown in Fig. 8, the base mounting fasteners B2 are attached to the screw holes provided in the fixing portions 12B, 12C, 13B, and 13C. This fixes the base body 11, the first mounting bracket 12, and the second mounting bracket 13 to the roof surface R shown in Fig. 1.

[0050] 1 are attached in that order to the base 10 of the stand. The support member 20 is fixed to the slide fitting S by a support member attachment fastener B1 shown in FIG.

[0051] Next, the receiving member 40 is temporarily fastened to the supporting member 20 using the first fastener 60 .

[0052] Next, the installation target arrangement member 31 on which the solar panel P is not attached is fitted into the receiving member 40 from the +Z side (upper side).

[0053] Next, the height level from the roof surface R to the top end of the installation target arrangement member 31 is adjusted to a desired height level by the worker. Then, the worker uses the first fastener 60 to fix the receiving member 40 to the supporting member 20.

[0054] Next, the solar panel P, the cover 37 having the spacer 37-2, and the fixing member receiving member 38 are placed on the upper 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 relative to each other to firmly fix the solar panel P.

[0055] Through the above, the work of installing the mounting base 1 and the solar panel P on the roof surface R of the building is completed as shown in Figs.

[0056] As described above, the mounting stand 1 and the base 10 of the mounting stand according to the present embodiment are provided with the first mounting bracket 12 and the second mounting bracket 13, so that the mounting strength can be ensured with a small fixing member. In detail, the pressing portion 12A of the first mounting bracket 12 is provided in the gap 11C between the wall portion 14 and the pair of side walls 11R and 11L, and is disposed on the upper surface of the bottom plate portion 11B, so that the first mounting bracket 12 is fixed to the base body 11, and the first mounting bracket 12 can fix the base body 11 to the roof surface R. In addition, the pressing portion 13A of the second mounting bracket 13 is provided on the upper surface of the bottom plate portion 11B, and is disposed in the slit 11D provided between the base body 11 and the pair of side walls 11R and 11L, so that the second mounting bracket 13 is fixed to the base body 11, and the second mounting bracket 13 can fix the base body 11 to the roof surface R. Therefore, by fixing the first mounting bracket 12 and the second mounting bracket 13 to the roof surface R, it is possible to reinforce the fixing strength of the base body 11 arranged on the roof surface R. On the other hand, in order to ensure the fixing strength with the base body 11 alone, it is necessary to increase the size of the base body 11, which increases the space required for storage and also increases the mass of the base body 11 and the transportation costs.

[0057] Moreover, the base 10 of the stand 1 according to this embodiment is formed by die casting. Therefore, in this embodiment, the manufacturing cost of the base 10 of the stand can be reduced compared to that manufactured by extruding metal such as aluminum or by press molding of a metal plate.

[0058] In addition, since the base 10 of the rack according to this embodiment is formed by die casting, the wall portion 14 can be formed in the base main body 11 at a position that can most easily prevent rainwater from the base mounting fastener B2. In this embodiment, the base 10 of the rack can be formed in a shape that protrudes in the +Z direction with respect to the roof surface R.

[0059] Moreover, in the base 10 of the rack according to the present embodiment, the wall portion 14 is integrally formed with the base body 11. Therefore, since the base body 11 and the wall portion 14 are formed separately, in this embodiment, the wall portion 14 can be easily arranged at a desired position on the roof surface R regardless of the skill of the installer, compared to a case where the base body 11 is attached to the roof surface R and then the wall portion 14 is attached to the base body 11. As a result, in this embodiment, the work efficiency of installing the base 10 of the rack on the roof surface R of the building can be improved.

[0060] In the embodiment, as shown in Fig. 3, the grooves 15R, 15L formed on the opposing surfaces of the pair of side walls 11R, 11L are formed with slide restriction portions 16R, 16L. Therefore, the slide restriction portions 16R, 16L restrict the sliding of the slide fitting S and the fixing unit 30 shown in Fig. 1 in the +X direction relative to the base 10 of the mount. As a result, the mount 1 according to the embodiment can improve the work efficiency of installation and removal on the roof surface R of a house.

[0061] (Modification) In the base 10 of the mounting stand according to the above embodiment, an example has been described in which the pressing portion 12A of the first mounting bracket 12 and the pressing portion 13A of the second mounting bracket 13 are disposed on the upper surface of the bottom plate portion 11B of the base body 11. The pressing portion 12A of the first mounting bracket 12 and the pressing portion 13A of the second mounting bracket 13 only need to be able to press the bottom plate portion 11B of the base body 11, and as shown in Figs. 9 and 10, a gap may be provided between the bottom plate portion 11B and the pressing portions 12A and 13A. In this case, as shown in Fig. 11, the pressing portions 12A and 13A have convex portions 12D and 13D on the surfaces facing the bottom plate portion 11B, respectively. The convex portions 12D and 13D press the upper surface of the bottom plate portion 11B of the base body 11, thereby allowing the base body 11 to be fixed to the roof surface R shown in Fig. 1. Furthermore, by providing gaps between bottom plate portion 11B and pressing portions 12A and 13A, rainwater accumulated on the upper surface of bottom plate portion 11B of base body 11 is drained. In this example, pressing portions 12A and 13A are provided with convex portions 12D and 13D on the surfaces facing bottom plate portion 11B, respectively, but convex portions may be formed on bottom plate portion 11B, or gaps may be provided between bottom plate portion 11B and pressing portions 12A and 13A by other configurations.

[0062] Also, as shown in Figs. 12 and 13, a gap may be provided between the base body 11 and the fixing parts 12B, 12C, 13B, and 13C of the first mounting bracket 12 and the second mounting bracket 13. Also, a wall part 14 is provided at the end of the base body 11 near the ridge (near the -X side) and formed to protrude in the +Z direction with respect to the roof surface R of the building shown in Fig. 1. As shown in Fig. 14, this wall part 14 can flow rainwater W flowing from the ridge side in the eaves direction (+X direction) while dividing it into left and right on the -Y side and +Y side. Furthermore, the rainwater W flows into the gap between the base body 11 and the fixing parts 12B, 12C, 13B, and 13C of the first mounting bracket 12 and the second mounting bracket 13 and is drained. This prevents the rainwater W flowing on the roof surface R of the building from getting on the base mounting fastener that attaches the rack 1 to the roof surface R. This can suppress the progression of decay of the base mounting fastener, for example, when the base mounting fastener is made of wood. In addition, the base 10 of the rack can suppress the deterioration of the base mounting fastener due to rainwater W. As a result, the base 10 of the rack can suppress the decrease in the fixing force of the rack 1 to the roof surface R. As shown in FIG. 11, when the first mounting bracket 12 and the second mounting bracket 13 are provided with convex parts 12D and 13D on the surfaces facing the bottom plate part 11B, the convex parts 12D and 13D come into contact with the pair of side wall parts 11R and 11L, and the first mounting bracket 12 and the second mounting bracket 13 can be prevented from shifting in the Y direction.

[0063] In the above-mentioned embodiment, the first mounting bracket 12 is provided in the gap 11C between the wall portion 14 and the pair of side walls 11R and 11L, and is disposed on the upper surface of the bottom plate portion 11B. However, the first mounting bracket 12 may be attached to one end of the base body 11. For example, as shown in Figs. 15 to 18, the first mounting bracket 12 may be disposed in the slit 11E provided between the base body 11 and the pair of side walls 11R and 11L, as in the case of the second mounting bracket 13. In this case, the base body 11 does not include the wall portion 14, but includes the slit 11E provided between the base body 11 and the pair of side walls 11R and 11L. As shown in Fig. 19, in addition to the gaps between the base body 11 and the fixing portions 12B, 12C, 13B, and 13C provided in the first mounting bracket 12 and the second mounting bracket 13, rainwater W flows and is drained from the gaps between the bottom plate portion 11B and the pressing portions 12A and 13A. In this way, rainwater W flowing on the roof surface R of the building shown in FIG. 1 is prevented from getting on the base mounting fastener that mounts the mount 1 to the roof surface R. This can prevent the base mounting fastener from decaying if it is made of wood, for example. In turn, the base 10 of the mount can prevent the base mounting fastener from deteriorating due to the rainwater W. As a result, the base 10 of the mount can prevent the fixing force of the mount 1 to the roof surface R from decreasing.

[0064] The first mounting metal fitting 12 may include a square band and be disposed so as to cover the upper portions of the pair of side walls 11R, 11L. In this manner, the first mounting metal fitting 12 can fix the base 10 of the mounting frame to the roof surface R.

[0065] In the above embodiment, the second mounting bracket 13 is provided on the upper surface of the pressing portion 13A and is disposed in the slit 11D provided between the base body 11 and the pair of side walls 11R, 11L. However, the second mounting bracket 13 may be attached to the other end of the base body. For example, the second mounting bracket 13 may include a square band and be disposed so as to cover the upper part of the pair of side walls 11R, 11L. In this way, the second mounting bracket 13 can fix the base 10 of the rack to the roof surface R.

[0066] In the above embodiment, an example has been described in which the support member 20 is slidably attached to the base 10 of the gantry, but the support member 20 only needs to be attached to the base 10 of the gantry, and the support member 20 may be directly fixed to the base 10 of the gantry. In this way, it is not necessary to form the grooves 15R, 15L in the side walls 11R, 11L, and the slide fittings S are also not necessary, so that the structure can be simplified.

[0067] 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]
