DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] (Embodiment 1) Hereinafter, the first 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 shown in FIG. 1 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 addition, in the first 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.

[0029] As shown in Figs. 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. The solar panel P is an example of a panel. In the present embodiment 1, the building to which the mount 1 is attached is a house having a roof eaves and a ridge. In other words, the mount 1 is for installing the solar panel P on the roof of the house, which is the installation location. The mount 1 according to the embodiment 1 includes a fixing part 30 and a base part 70 that supports the fixing part 30. The base part 70 also includes a receiving member 40, a base unit 50, and a first fastener 60.

[0030] As shown in FIG. 2 and FIG. 3, the fixing part 30 fixes the solar panel P. The fixing part 30 is fixed to the receiving member 40 by the first fastener 60. The fixing part 30 has a crosspiece member 31 as a crosspiece and an attachment part 35. Each component of the fixing part 30 is formed of, for example, metal. However, this is not limited to this. Each component of the fixing part 30 may be formed of a material other than metal. For example, each component of the fixing part 30 may be formed of a highly rigid material such as resin or ceramic. In addition, some of the components of the fixing part 30 may be formed of different materials. However, each component of the fixing part 30 is preferably formed of metal, and more preferably, all of the components of the fixing part 30 are preferably formed of the same metal material from the viewpoint of manufacturing costs.

[0031] As shown in FIG. 1, the crosspiece member 31 is a horizontal crosspiece extending in the Y-axis direction. The crosspiece 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 crosspiece member 31 is formed, for example, by extruding metal. Specifically, the crosspiece member 31 is formed, for example, by extruding aluminum. In the first embodiment, the crosspiece member 31 is a horizontal crosspiece extending in a direction perpendicular to the ridge-edge direction. However, this is not limited thereto. The crosspiece member 31 may be a crosspiece other than a horizontal crosspiece. For example, the crosspiece member 31 may be a vertical crosspiece extending in the same direction as the ridge-edge direction. The crosspiece member 31 may also be a crosspiece other than a vertical crosspiece extending in a direction intersecting the ridge-edge direction.

[0032] The crosspiece member 31 has a generally rectangular cylindrical shape as shown in Fig. 5. The crosspiece member 31 has two side walls 31b, 31b spaced apart in the X-axis direction, a bottom wall 31c connecting the -Z side ends of the two side walls 31b, 31b, and upper wall parts 31d, 31d protruding inward from the +Z side ends of the two side walls 31b, 31b, respectively.

[0033] Both ends of the bottom wall portion 31c protrude beyond the two side wall portions 31b, 31b, and these protruding portions form first locking portions 31e. The first locking portions 31e are formed in a linear shape extending along the Y-axis direction.

[0034] A gap of width W1 is provided between the two upper wall portions 31d, 31d, so that a slit-shaped opening 31a of width W1 is formed on the +Z side surface of the crosspiece member 31, as shown in FIG.

[0035] As shown in FIG. 5, the crosspiece member 31 is formed with first protrusions 31f, 31f protruding in the -Z direction from the tip of the upper wall portion 31d, a partition portion 31g dividing the internal space of the crosspiece member 31 into two, and second protrusions 31h, 31h protruding inward from the inner surfaces of the side wall portions 31b, 31b.

[0036] The first protrusions 31f, 31f, together with the upper wall portions 31d, 31d, form the walls of the slit-shaped opening 31a. Inside the crosspiece member 31, grooves 31i defined by the first protrusions 31f, the upper wall portion 31d, and the side wall portions 31b are formed along the Y-axis direction on both sides of the opening 31a. Parts of nuts 39 shown in FIG. 7 are fitted into the grooves 31i, 31i, as described later.

[0037] 5, the partition wall 31g is provided at a height position of about 1 / 3 from the bottom in the height direction (Z-axis direction) of the crosspiece member 31. Providing the partition wall 31g can increase the rigidity of the crosspiece member 31. On the +Z side of the partition wall 31g, a groove portion 31j is formed which is defined by the side walls 31b, 31b and the partition wall portion 31g and is open upward in the figure by a slit-shaped opening 31a. The groove portion 31j thus formed forms an accommodation space 31k inside the crosspiece member 31 capable of accommodating various components.

[0038] The second protrusions 31h, 31h are disposed at the same height between the upper wall portion 31d and the partition wall portion 31g with a gap between their tips. The second protrusions 31h, 31h increase the rigidity of the crosspiece member 31 and abut against a nut 39 shown in Fig. 7 described later to roughly position the nut 39. This makes it easier to fit a part of the nut 39 into the grooves 31i, 31i.

[0039] As shown in Fig. 6, the cable 2 drawn out from the solar panel P is accommodated in the accommodation space 31k inside the crosspiece member 31. The cable 2 is passed through the opening 31a and between the second protrusions 31h, 31h as indicated by the arrow A1, and accommodated in the accommodation space 31k. In this manner, in the first embodiment, the cable 2 is accommodated in the accommodation space 31k, but what is accommodated in the accommodation space 31k is not limited to this, and something other than the cable 2 may be accommodated. For example, the accommodation space 31k may accommodate a cable connector to be connected to the cable 2.

[0040] Further, the upper surface of the rail member 31 facing the +Z side forms a mounting surface 31p on which the solar panel P is placed. This mounting surface 31p on the +Z side is formed as a surface parallel to the YZ plane so that the solar panel P can be easily placed thereon.

[0041] The mounting portions 35 are attached to the crosspiece members 31 as shown in Fig. 3 and Fig. 4, and sandwich the solar panel P between the mounting portions 35 and the crosspiece members 31. In this embodiment, as shown in Fig. 1, three mounting portions 35 are provided at intervals in the longitudinal direction of the crosspiece members 31. Two of the mounting portions 35 provided on both sides are end mounting portions 35a, which sandwich one solar panel P between the crosspiece members 31. The mounting portion 35 provided in the middle in Fig. 1 is a middle mounting portion 35b, which sandwiches two solar panels P between the crosspiece members 31 on both sides as shown in Fig. 4.

[0042] The end mounting portion 35a has a first mounting portion 32 that presses the solar panel P toward the batten member 31 and clamps it between the batten member 31, and a second mounting portion 33 that is placed on the mounting surface 31p of the batten member 31 and is combined with the first mounting portion 32 so that the first mounting portion 32 can slide along the Z axis.

[0043] On the other hand, the intermediate mounting portion 35b has the first mounting portion 32 but does not have the second mounting portion 33. Other than that, the configuration of the intermediate mounting portion 35b is similar to the configuration of the end mounting portion 35a.

[0044] A cross section of the first mounting portion 32 taken in a direction perpendicular to the X-axis has the same shape and size along the X-axis direction, as shown in Fig. 3. When viewed in a direction parallel to the X-axis, the first mounting portion 32 has two side walls 32-1 and 32-2, a connecting plate portion 32-3, two extension portions 32-4 and 32-5, and a protruding plate portion 32-6, as shown in Fig. 8.

[0045] The two side wall portions 32-1, 32-2 are spaced apart in the Y-axis direction and are disposed opposite each other. The connecting plate portion 32-3 connects one end edge (on the -Z side) of the two side wall portions 32-1, 32-2 to each other. The two extension portions 32-4, 32-5 extend outward from the other end edge (on the +Z side) of the two side wall portions 32-1, 32-2 that faces one end edge. The extension portion 32-5 comes into contact with the first surface P1 facing the +Z side of the solar panel P placed on the mounting surface 31p of the crosspiece member 31 as shown in FIG. 4, and presses the solar panel P toward the crosspiece member 31. The pressing direction in which the extension portion 32-5 presses the solar panel P is the -Z direction. In the intermediate mounting portion 35b shown in FIG. 4, the extension portion 32-4 as well as the extension portion 32-5 presses the solar panel P toward the crosspiece member 31. The protruding plate portion 32-6 is an insertion portion that protrudes in the -Z direction from the connecting plate portion 32-3 as shown in FIG. 8, and is a plate-shaped member parallel to the XZ plane. The protruding plate portion 32-6 protrudes from the edge portion on the +Y side of the connecting plate portion 32-3, and is formed in a manner in which the side wall portion 32-1 is extended to the -Z side. The position of the protruding plate portion 32-6 on the connecting plate portion 32-3 is not limited to being formed on the edge portion, and can be any position as long as it is a position that allows sliding along the Z axis (in the pressing direction) as described later.

[0046] As shown in FIG. 7, the first mounting portion 32 has a recess 32a extending in one direction defined by two side walls 32-1 and 32-2 and a connecting plate portion 32-3. In this embodiment, as shown in FIG. 1, the first mounting portion 32 is disposed so that the extending direction of the recess 32a is parallel to the X-axis, that is, the extending direction of the recess 32a is perpendicular to the extending direction of the slit-shaped opening 31a. The length of the first mounting portion 32 in the X-axis direction is longer than the length (width) of the crosspiece member 31 in the X-axis direction. Therefore, the first mounting portion 32 disposed on the crosspiece member 31 protrudes from both sides of the crosspiece member 31. As shown in FIG. 9, the connecting plate portion 32-3 defining a part of the recess 32a of the first mounting portion has a bolt insertion hole 32-3a through which a bolt 38 described later is inserted.

[0047] As shown in FIGS. 7 and 8, the second attachment portion 33 has a substantially rectangular bottom wall portion 33-1, and a first rising portion 33-2 and a second rising portion 33-3 rising from the bottom wall portion 33-1 with a gap between them.

[0048] The bottom wall portion 33-1 is plate-shaped and has a bottom surface 33-1a that is placed on the placement surface 31p of the crosspiece member 31. As shown in Fig. 7, the bottom wall portion 33-1 has a notch 3 that is cut inward from the center of one side on the -Y side and has a shape that includes a semicircular portion. A bolt 38 that has passed through the first mounting portion 32 is passed through this notch 3.

[0049] The first rising portion 33-2 is a rectangular plate rising from the upper surface 33-1b of the bottom wall portion 33-1 along the opposite side on the +Y side opposite the side on which the notch 3 is formed. The first rising portion 33-2 has a long side coinciding with the opposite side on the +Y side of the bottom wall portion 33-1 and is formed perpendicular to the bottom wall portion 33-1. The first rising portion 33-2 has a height (length in the Z-axis direction) H1 from the upper surface 33-1b of the bottom wall portion 33-1.

[0050] As shown in FIG. 8, the second rising portion 33-3 is a rectangular plate rising from the upper surface 33-1b of the bottom wall portion 33-1 with a gap G1 on the -Y side from the first rising portion 33-2. The second rising portion 33-3 is formed parallel to the first rising portion 33-2 and perpendicular to the bottom wall portion 33-1. The second rising portion 33-3 has a height H2 from the upper surface 33-1b of the bottom wall portion 33-1. The height H2 of the second rising portion 33-3 is lower than the height H1 of the first rising portion 33-2. The gap G2 between the first rising portion 33-2 and the second rising portion 33-3 forms an insertion groove 33a as an insertion portion into which the protruding plate portion 32-6 is inserted.

[0051] As shown in FIG. 9(a), the protruding plate portion 32-6 of the first mounting portion 32 is inserted between the first rising portion 33-2 and the second rising portion 33-3. The thickness t1 of the protruding plate portion 32-6 shown in FIG. 8 is approximately equal to the interval G1 between the first rising portion 33-2 and the second rising portion 33-3, or is small enough not to cause the inserted first mounting portion 32 to rattle. In addition, the protruding length L1 of the protruding plate portion 32-6 from the connecting plate portion 32-3 is, for example, the same as the height H2 from the upper surface 33-1b of the second rising portion 33-3. This allows the protruding plate portion 32-6 to be inserted into the insertion groove 33a over the entire length of the protruding length L1. In addition, the first mounting portion 32 can be slid smoothly along the Z axis without rattling with respect to the second mounting portion 33 until the protruding plate portion 32-6 comes out of the insertion groove 33a.

[0052] As shown in FIGS. 7 and 8, the bottom wall portion 33-1 is formed with two second locking portions 33b, 33b extending in the -Y direction from one side on the -Y side.

[0053] As shown in FIG. 7, the second locking portion 33b is formed on each of both ends of the bottom wall portion 33-1 in the X-axis direction. The two second locking portions 33b, 33b have the same shape and size. A gap G2 between the two second locking portions 33b, 33b is wider than the width of the crosspiece member 31 in the X-axis direction. Therefore, when the second mounting portion 33 is placed on the crosspiece member 31, the two second locking portions 33b, 33b are disposed on both sides of the crosspiece member 31, as shown in FIG. 3. Note that the second locking portion 33b is stepped down on the -Z side from the bottom wall portion 33-1, as shown in FIG. 8, and has an upper surface 33ba (surface on the +Z side) that is offset downward (in the -Z direction) from an upper surface 33-1b (surface on the +Z side) of the bottom wall portion 33-1. As a result, when the second attachment portion 33 is placed on the mounting surface 31p, the upper surface 33ba of the second locking portion 33b becomes approximately flush with the mounting surface 31p. Therefore, as shown in Fig. 4, the second locking portion 33b comes into contact with a second surface P2 (opposite the first surface P1) facing the -Z side of the solar panel P placed on the mounting surface 31p.

[0054] 3, the end mounting portion 35a has, as fasteners, a bolt 38 for applying axial force for clamping the solar panel P between the crosspiece member 31 and the first mounting portion 32, and a nut 39 that screws into the bolt 38. The crosspiece member 31 and the first mounting portion 32 are fastened together by the bolt 38 and the nut 39.

[0055] The bolt 38 is a hexagonal socket bolt with a hexagonal hole 38b formed in the head 38a. As shown in FIG. 9(a), the bolt 38 is inserted through a bolt insertion hole 32-3a formed in the first mounting portion 32 and a notch 3 formed in the second mounting portion 33. The height of the head 38a of the bolt 38 is set lower than the depth of the recess 32a formed in the first mounting portion 32. This makes it possible to prevent the head 38a of the bolt 38 from protruding from the first mounting portion 32.

[0056] As shown in the enlarged view of Fig. 8, the nut 39 has a rhombus-shaped quadrangle having opposing parallel short sides 39c, 39c and opposing parallel long sides 39d, 39d when viewed from the +Z side, and a female thread 39e is formed in the center thereof to screw into the bolt 38. As shown in Fig. 10(a), the width W2 between the long sides 39d of the nut 39 is narrower than the width W1 of the opening 31a of the crosspiece member 31. On the other hand, as shown in Fig. 10(b), the width W3 between the short sides 39c of the nut 39 is wider than the width W1 of the opening of the crosspiece member 31.

[0057] Groove portions 39b, 39b are formed on the inside of the +Z side surface of the nut 39 at a predetermined distance from the opposing short sides 39c, 39c. Third locking portions 39a, 39a protruding in the +Z direction from the bottoms of the groove portions 39b, 39b are formed on the +Z side surface of the nut 39 along the respective short sides 39c.

[0058] The nut 39 is accommodated in the accommodation space 31k in the crosspiece member 31 in a state where it is screwed onto the bolt 38, as shown in FIG. 9(b). When accommodating the nut 39 in the accommodation space 31k, the nut 39 is first put into a first state in which the long sides 39d, 39d are parallel to the Y axis along which the opening 31a extends, as shown in FIG. 10(a). This allows the nut 39 to be inserted into the accommodation space 31k of the crosspiece member 31 through the opening 31a. Then, the nut 39 inserted into the accommodation space 31k is rotated around the axis of the bolt 38 to a second state in which the short sides 39c, 39c are parallel to the Y axis along which the opening 31a extends, as shown in FIG. 10(b). Then, by fastening the bolt 38, the third locking portions 39a, 39a of the nut 39 can be fitted into the grooves 31i, 31i formed in the crosspiece member 31, as shown in FIG. 9(b).

[0059] 1 does not have the second mounting portion 33. The rest of the configuration of the intermediate mounting portion 35b is the same as that of the end mounting portion 35a, and includes the first mounting portion 32, a bolt 38, and a nut 39. The bolt 38 is inserted only through the bolt insertion hole 32-3a formed in the first mounting portion 32, and is screwed into the nut 39.

[0060] As shown in Fig. 11, the receiving member 40 receives the fixing portion 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. The receiving member 40 has a receiving member main body 41 to which the first fastener 60 is attached, and a clamping portion 42 provided at the upper end of the receiving member main body 41.

[0061] The receiving member body 41 is formed with a hole 40a (inserted portion) into which the first fastener 60 is inserted. The receiving member body 41 also has side walls 41-1 and 41-2 and a bottom plate portion 41-3.

[0062] The side walls 41-1 and 41-2 are formed in a plate shape parallel to the YZ plane. The hole 40a is formed penetrating the side walls 41-1 and 41-2 in the X-axis direction. Of the side walls 41-1 and 41-2, the side wall 41-2 is a portion that comes into contact with and is fixed to the base unit 50 by the first fastener 60.

[0063] The bottom plate portion 41-3 is formed in a plate shape parallel to the XY plane. The bottom plate portion 41-3 connects the lower ends (the ends on the -Z side) of the side wall portions 41-1 and 41-2.

[0064] The sandwiching portion 42 is a portion that sandwiches the lower end of the crosspiece member 31. The sandwiching portion 42 is formed with a first locked portion 40b that locks with the first locking portion 31e of the crosspiece member 31. The sandwiching portion 42 has extension portions 42-1, 42-2 that extend upward (in the +Z direction) from the upper ends (ends on the +Z side) of the side wall portions 41-1, 41-2 of the receiving member main body 41. The first locked portion 40b is formed on each of the opposing surfaces where the extension portions 42-1 and 42-2 face each other.

[0065] 1, 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 fixing part 30 via the receiving member 40. As shown in FIG 11, the base unit 50 has a base 10, a sliding fitting S (sliding member), a supporting member 20, and a fastener B1 for attaching the supporting member.

[0066] The base 10 is formed of, for example, a metal. Specifically, the base 10 is formed by, for example, die casting using a mold. The base 10 includes a base body 15 and a wall portion 16.

[0067] The base body 15 is fixed to the roof surface R. The base body 15 is also formed with a first groove 10a (support member fixing groove) as a fixing groove used to fix the support member 20. The base body 15 has a groove forming portion 11 in which the first groove 10a is provided, and plate-like flange portions 14R, 14L formed by projecting from the groove forming portion 11 in the +Y direction and the -Y direction.

[0068] A first groove 10a is formed along a first direction D1, which is the same direction as the ridge direction, in the groove forming portion 11. The groove forming portion 11 has a pair of side wall portions 11R, 11L that form the first groove 10a on the inside.

[0069] Further, a pair of second grooves 12R, 12L into which a part of the slide fitting S fits are formed on the opposing surfaces of the pair of side walls 11R, 11L.

[0070] The second grooves 12R, 12L are formed to extend along the first direction D1 (the ridge direction). The second grooves 12R, 12L are formed with slide regulating portions 13R, 13L. In the present embodiment 1, the slide regulating portions 13R, 13L are formed in the second grooves 12R, 12L, respectively, so that two slide regulating portions 13R, 13L are formed. However, this is not limited to this. The slide regulating portions 13R, 13L may be formed in one of the second grooves 12R, 12L.

[0071] The flange portions 14R and 14L are each formed with a fastener insertion hole 14a-1, which is a circular hole into which a base mounting fastener B2 (FIG. 2) for mounting the base 10 is inserted, penetrating the flange portions 14R and 14L in the Z-axis direction.

[0072] As shown in Fig. 11, the wall portion 16 is provided at an end portion of the base body 15 closer to the ridge (closer to the -X side), and is formed to protrude upward (in the +Z direction) with respect to the XY plane. The wall portion 16 is formed integrally with the base body 15 by casting. The wall portion 16 is used, for example, to prevent rainwater flowing from the ridge side from splashing on the fastener inserted into the fastener insertion hole 14a-1. The wall portion 16 is formed with a first inclined surface 16-1, a second inclined surface 16-2, and a protruding surface 16-3.

[0073] The base 10 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 15 and the wall portion 16. However, the present invention is not limited to this, and any manufacturing method other than casting may be used as long as it is capable of integrally forming the base body 15 and the wall portion 16. The base 10 is preferably manufactured by die casting, which is a type of casting. However, the present invention is not limited to this. The base 10 may be manufactured by casting other than die casting, such as a sand mold, a plaster mold, a resin mold, or lost wax.

[0074] 3, the sliding fitting S is fitted into the first groove 10a of the base 10 so as to be slidable in a first direction D1. The sliding fitting S is attached to the base 10 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. A screw hole Sa is formed in this sliding fitting S.

[0075] 11, the fastener B1 for attaching a support member is screwed into the screw hole Sa, and the inner peripheral surface of the screw hole Sa is formed as a female thread surface. The screw hole Sa is formed penetrating in the Z-axis direction.

[0076] In addition to the screw holes Sa, a pair of fitting portions (not shown) are formed in the slide fitting S. The fitting portions are portions that fit into second grooves 12R, 12L formed in side walls 11R, 11L of the base 10. The fitting portions have an L-shaped YZ cross section.

[0077] 11, 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.

[0078] 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.

[0079] 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 1, 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.

[0080] 11, 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 the screw hole Sa 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.

[0081] The first fastener 60 has a bolt 61 and a nut 62. The bolt 61 is, for example, a bolt or a screw. In the first 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 40a of the receiving member 40 may be a screw hole, and the bolt 61 may be screwed into this hole 40a. In this case, the nut 62 can be omitted, and the first fastener 60 is composed of only the bolt 61.

[0082] A method for constructing the mounting base 1 configured as above will be described with reference to the drawings.

[0083] When installing the mounting stand 1 and the solar panel P on the roof surface R of a building, as shown in Fig. 11, a worker installing the mounting stand 1 on the roof surface R first attaches the base 10, the sliding bracket S, and the support member 20 to the roof surface R in that order. The base 10 is fixed to the roof surface R with a base mounting fastener B2 (Fig. 2). The support member 20 is fixed to the sliding bracket S with a support member mounting fastener B1.

[0084] Next, the worker uses the first fastener 60 to temporarily fasten the receiving member 40 to the supporting member 20 .

[0085] Next, the worker fits the crosspiece member 31, to which the solar panel P is not attached, from the +Z side (upper side) into the temporarily fixed receiving member 40. When the crosspiece member 31 is fitted into the receiving member 40, the first locking portion 31e of the crosspiece member 31 is locked to the first locked portion 40b of the receiving member 40.

[0086] Next, the worker adjusts the height level from the roof surface R to the upper end of the crosspiece member 31 to the worker's desired height level. Then, the worker uses the first fastener 60 to fix the receiving member 40 to the supporting member 20.

[0087] Next, the worker places two end mounting parts 35a and one middle mounting part 35b shown in Fig. 1 on the upper surface of the crosspiece member 31. Specifically, the worker rotates the nuts 39 of the end mounting part 35a and the middle mounting part 35b so that the long sides 39d, 39d are parallel to the Y axis as shown in Fig. 10(a). This enables the worker to insert the nuts 39 into the accommodation space 31k of the crosspiece member 31 through the opening 31a.

[0088] Next, the worker rotates the nut 39 inserted into the accommodation space 31k so that the short sides 39c, 39c are parallel to the Y-axis as shown in Fig. 10(b). In this way, the worker can bridge the nut 39 across the second protruding portion 31h shown in Fig. 9(b) and temporarily place it on the second protruding portion 31h.

[0089] Next, when arranging the end mounting portion 35a, the worker inserts the protruding plate portion 36 of the first mounting portion 32 into the insertion groove 33a formed in the second mounting portion 33, as shown in FIG. 9(a), and combines the first mounting portion 32 and the second mounting portion 33. Then, the worker slides the nut 39 along the Y-axis direction inside the accommodation space 31k to arrange the mounting portion 35 in a desired position. Then, the worker places the bottom wall portion 33-1 of the second mounting portion 33 on the placement surface 31p of the crosspiece member 31, and places the combined first mounting portion 32 and second mounting portion 33 on the crosspiece member 31.

[0090] Next, the worker clamps and temporarily fixes the solar panel P using the end mounting portion 35a and the intermediate mounting portion 35b arranged on the crosspiece member 31. Specifically, the worker clamps the solar panel P shown on the right side of FIG. 4 between the extension portion 32-5 of the end mounting portion 35a and the mounting surface 31p of the crosspiece member 31, and hooks the second locking portion 33b of the end mounting portion 35a onto the second surface P2 of the solar panel P. The worker also clamps the solar panel P shown on the right side of FIG. 4 between the extension portion 32-4 of the intermediate mounting portion 35b and the mounting surface 31p of the crosspiece member 31. This allows the worker to temporarily fix the solar panel P shown on the right side of FIG. 4.

[0091] Similarly, the worker temporarily fixes the solar panel P shown on the left side in FIG. 4 using the end mounting portion 35a and the middle mounting portion 35b.

[0092] Finally, the worker secures the solar panel P to the frame 1 by fully tightening the bolts 38 of the end mounting portion 35a and the middle mounting portion 35b.

[0093] With 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.

[0094] According to the mount 1 according to the first embodiment, the mounting portion 35 for mounting the solar panel P to the crosspiece member 31 has the second mounting portion 33 placed on the crosspiece member 31, and the first mounting portion 32 that sandwiches the solar panel P between the crosspiece member 31 and is combined with the solar panel P so as to be slidable in a direction to press the solar panel P. This makes it possible to prevent the first mounting portion 32 from falling over due to the second mounting portion 33 placed on the crosspiece member 31, and to stabilize the posture of the mounting portion 35. In this way, stabilizing the mounting portion 35 makes it easier to mount the solar panel P, and improves the efficiency of the panel mounting work.

[0095] The reason why the mounting portion 35 is stable will be described in more detail. As shown in Fig. 12, the second mounting portion 33 is provided with a bottom wall portion 33-1 that is placed on the placement surface 31p of the crosspiece member 31. The length L2 of contact between the placement surface 31p and the bottom wall portion 33-1 can be set to any length, and a sufficient length that can stabilize the posture of the mounting portion 35 can be ensured. Since the first mounting portion 32 is combined with the second mounting portion 33 whose posture is stabilized in this way, it is possible to prevent the mounting portion 35 from falling in the direction of the arrow A1 or the direction of the arrow A2.

[0096] Furthermore, the first mounting portion 32 and the second mounting portion 33 are combined to be slidable in a direction parallel to the pressing direction of the solar panel P by inserting the protruding plate portion 32-6 formed in the first mounting portion 32 into the insertion groove 33a formed in the second mounting portion 33. This allows the axial force introduced into the bolt 38 to be smoothly transmitted to the first mounting portion 32, and the solar panel P can be clamped between the first mounting portion 32 and the crosspiece member 31. This improves the efficiency of the panel mounting work.

[0097] 10(a) and 10(b), the width of the nut 39 has some parts that are wider and some parts that are narrower than the width of the opening 31a formed in the crosspiece member 31. This allows the nut 39 to be hooked onto the crosspiece member 31 by rotating the nut 39 around the axis of the bolt 38 after it has been accommodated in the accommodation space 31k of the crosspiece member 31. This makes it easier to tighten the bolt 38 thereafter, improving the efficiency of the panel installation work.

[0098] 9(b), the nut 39 is formed with third locking portions 39a, 39a that fit into the grooves 31i, 31i formed in the crosspiece member 31. This makes it possible to prevent the nut 39 from rotating when the bolt 38 is tightened, and makes it easy to tighten the bolt 38.

[0099] 3, a notch 3 is formed in the bottom wall portion 33-1 of the second mounting portion 33, cut inward from one side on the -Y side, for inserting the bolt 38. As a result, even after the intermediate mounting portion 35b, which does not have the second mounting portion 33, is placed on the crosspiece member 31, the second mounting portion 33 can be attached later by passing the bolt 38 through the notch 3. In this way, the presence or absence of the second mounting portion 33 can be selected as necessary, thereby improving the efficiency of the panel mounting work.

[0100] Further, the second mounting portion 33 is formed with a second locking portion 33b that extends in a stepped manner from the bottom wall portion 33-1 and comes into contact with the second surface P2 of the solar panel P. As a result, even if a force acts on the mounting portion 35 in the direction shown by the arrow A2 in Fig. 12, the second locking portion 33b can be caught by the solar panel P, preventing the mounting portion 35 from falling over. This can improve the efficiency of the panel mounting work.

[0101] 3, the second locking portions 33b stepped down from the bottom wall portion 33-1 are disposed on both sides of the crosspiece member 31. As a result, even if a force acts on the second mounting portion 33 in a direction along the X-axis, the second locking portions 33b can be caught by the side surfaces of the crosspiece member 31, and the posture of the second mounting portion 33 can be maintained. This can improve the efficiency of the panel mounting work.

[0102] (Embodiment 2) In the above-mentioned embodiment 1, as shown in Fig. 7, the bottom wall portion 33-1 of the second mounting portion 33 is formed with a notch 3 through which the shaft portion of the bolt 38 is inserted. However, this is not limited to this. As shown in Fig. 13, the bottom wall portion 33-1 of the second mounting portion 33 may be formed with a bolt hole 4 through which the shaft portion of the bolt 38 is inserted, instead of the notch 3. Note that each configuration of embodiment 2 has many parts in common with the configuration of embodiment 1. Therefore, the common parts are denoted with the same reference numerals, and duplicated explanations will be omitted.

[0103] In the mount 101 according to the second embodiment, when the second mounting portion 33 receives a force P3 from the solar panel P, the inner surface of the bolt hole 4 comes into contact with the bolt 38, as compared to the first embodiment. In this manner, the second mounting portion 33 gets caught on the bolt 38, and thus, in the mount 101, the first mounting portion 32 and the second mounting portion 33 are stably disposed relative to the crosspiece member 31. As a result, the mount 101 can stabilize the fixation of the solar panel P to the crosspiece member 31.

[0104] Moreover, the mount 101 according to the second embodiment also provides the same effects as those of the first embodiment.

[0105] In the second embodiment, the bolt holes 4 are perfect circular holes, but this is not limiting. The bolt holes 4 may have a shape other than a perfect circular hole.

[0106] (Embodiment 3) The first mounting portion 132 and the second mounting portion 133 of the mount 201 according to the third embodiment are shorter in length in the X-axis direction by about 2 / 3 compared to the first mounting portion 32 and the second mounting portion 33 in the first embodiment. Therefore, as shown in Fig. 16, the amount of protrusion of the first mounting portion 132 and the second mounting portion 133 from the crosspiece member 31 in the direction parallel to the X-axis is small. In the present embodiment, as shown in Fig. 14(a), one second locking portion 133b extends from the center of one side on the -Y side of the bottom wall portion 33-1 toward the -Y side.

[0107] The shape and size of a cross section of the first mounting portion 132 taken in a direction perpendicular to the X-axis is the same as that of the cross section of the first mounting portion 32 in embodiment 1. A bolt insertion hole 32-3a (FIG. 14(b)) through which the bolt 38 is inserted is formed in the center of the connecting plate portion 32-3.

[0108] The second mounting portion 133 is shorter in length in the X-axis direction than the second mounting portion 33 in the first embodiment, being about 2 / 3. As shown in FIG. 15, the bottom wall portion 33-1 is formed with a bolt hole 4 through which the bolt 38 is inserted, and a second locking portion 133b is protruded from the center of one side on the -Y side. The second locking portion 133b is formed to be stepped down from the bottom wall portion 33-1, similar to the second locking portion 33b in the first embodiment. The width W2 of the second locking portion 133b in the X-axis direction is narrower than the width W1 (FIG. 16) of the slit-shaped opening 31a of the crosspiece member 31. As a result, as shown in FIG. 16, when the second locking portion 133b is placed on the placement surface 31p of the crosspiece member 31, the second locking portion 133b is accommodated in the accommodation space 31k of the crosspiece member 31 through the opening 31a.

[0109] 15, the second mounting portion 133 has a trapezoidal tubular portion 134, the cross section of which is trapezoidal when cut in a direction perpendicular to the X-axis, at the end on the +Y side. The trapezoidal tubular portion 134 has a first rising portion 33-2 that defines a part of the insertion groove 33a, a slanted wall portion 134a that extends obliquely from the end edge on the +Y side of the bottom wall portion 33-1, a side wall portion 134b that extends from the slanted wall portion 134a, and an upper plate portion 134c that connects the first rising portion 33-2 and the side wall portion 134b. Among these, the first rising portion 33-2 and the side wall portion 134b form the bottom portion of the trapezoidal tubular portion 134. The slanted wall portion 134a and the upper plate portion 134c form the legs of the trapezoidal tubular portion 134. The upper plate portion 134c is perpendicular to the first rising portion 33-2 and the side wall portion 134b.

[0110] According to the mounting stand 201 of the third embodiment, the second locking portion 133b disposed in the opening 31a of the crosspiece member 31 is hooked onto the second surface P2 of the solar panel P. This makes it possible to prevent the mounting portion 135 disposed on the crosspiece member 31 from falling over, thereby improving the efficiency of the panel mounting work.

[0111] Furthermore, by forming trapezoidal tubular portion 134 at the end on the +Y side of second mounting portion 133, it becomes easier to grasp second mounting portion 133. As a result, even after first mounting portion 132 and second mounting portion 133 are combined, trapezoidal tubular portion 134 can be grasped to position mounting portion 135 in a desired position or move it, improving the efficiency of the panel mounting work.

[0112] Furthermore, by shortening the length of the mounting portion 135 in the X-axis direction, material costs can be reduced.

[0113] Moreover, the mount 201 according to the third embodiment can also provide the same effects as those of the first and second embodiments.

[0114] (Embodiment 4) In the above embodiment, as shown in FIG. 7, for example, the mounting portion 35 has been described as having the second mounting portion 33 and the nut 39 which are independent of each other. On the other hand, as shown in FIG. 19, the mount 301 according to the fourth embodiment has the second mounting portion 250 which has both the functions of the second mounting portion 33 and the nut 39. As shown in FIG. 17(a) and FIG. 17(b), the second mounting portion 250 is used in combination with the first mounting portion 132. The first mounting portion 132 and the bolt 38 are the same as those shown in FIG. 15.

[0115] As shown in Figure 18(a), the second mounting portion 250 has a bottom wall portion 251, a pair of support portions 252, 252 rising from the bottom wall portion 251 and extending along the Y-axis, a pair of side wall portions 253, 253 formed continuously along the Y-axis direction from the pair of support portions 252, 252 and higher than the support portions 252, 252, and an upper plate portion 254 connecting the +Z side end edges of the side wall portions 253, 253.

[0116] The bottom wall portion 251 has a substantially rectangular shape when viewed from the +Z side. As shown in Fig. 19, when the mounting portion 235 is placed on the crosspiece member 31, a first surface 251a on the -Z side comes into contact with a second protruding portion 31h of the crosspiece member 31. As shown in Figs. 18(a) and 18(b), the bottom wall portion 251 has a female thread 251b that screws with the bolt 38 in an area sandwiched between the side walls 253, 253. The bottom wall portion 251 has a third locking portion 251c that protrudes in the +Z direction along a side (the +X side and the -X side) that extends parallel to the Y axis.

[0117] As shown in Fig. 17(a), the support portions 252, 252 are portions that protrude toward the +Z side from a second surface 251d opposite to the first surface 251a of the bottom wall portion 251. As shown in Fig. 17(b), the support portions 252, 252 abut against the solar panel P to be placed. As shown in Fig. 17(a), the support portions 252, 252 are spaced apart from each other in the X-axis direction and extend along the Y-axis from the end on the -Y side to approximately the center in the Y-axis direction of the bottom wall portion 251.

[0118] The side walls 253, 253 are generally rectangular plate-like portions protruding in the +Z direction from the second surface 251d of the bottom wall portion 251. The side walls 253, 253 extend from generally the center of the bottom wall portion 251 in the Y-axis direction to the end portion on the +Y side.

[0119] The upper plate portion 254 connects the +Z side ends of the sidewall portions 253, 253 to each other. The length of the upper plate portion 254 in the Y-axis direction is the same as the length of the sidewall portions 253, 253 in the Y-axis direction. The +Y side end face of the upper plate portion 254 is flush with the +Y side end faces of the sidewall portions 253, 253, as shown in FIG. 17(b). The +Y side end faces of the upper plate portion 254 and the sidewall portions 253, 253 form a slide surface 250a that comes into contact with the protruding plate portion 32-6 of the first mounting portion 32 that slides parallel to the Z axis. In addition, a female screw 254a that screws into the bolt 38 is formed in the center of the upper plate portion 254, as shown in FIG. 18(a).

[0120] When the second attachment portion 250 formed in this manner is viewed from the -Y side, as shown in Fig. 18(b), the +X side and -X side of the bottom wall portion 251 protrude outward beyond the support portion 252 and the side wall portions 253, 253. A third locking portion 251c is formed at the tip of the protruding portion of the bottom wall portion 251. The width W4 in the X-axis direction of the bottom wall portion 251 is wider than the width of the opening 31a of the crosspiece member 31 shown in Fig. 19.

[0121] Next, a procedure will be described for arranging the mounting portions 235 on the crosspiece members 31 and attaching the solar panel P. The procedure for attaching the crosspiece members 31 to the roof surface R of the building is as described above.

[0122] After attaching the crosspiece member 31, first, as shown in Fig. 17(b), the worker brings the protruding plate portion 32-6 into contact with the slide surface 250a of the second mounting portion 250. Then, the worker screws the bolt 38 inserted into the first mounting portion 132 into the female threads 254a and 251b (both shown in Fig. 18(b)) formed on the second mounting portion 250. In this manner, the mounting portion 235 is left in a state in which the first mounting portion 132 and the second mounting portion 250 are combined with each other by the bolt 38.

[0123] Next, the worker rotates the attachment portion 235 about the Y axis to place it in an inclined position, as shown in FIG. 20(a).

[0124] 20(b), the worker inserts the tilted attachment portion 235 into the opening 31a formed in the crosspiece member 31. As described above, the width of the bottom wall portion 251 in the X-axis direction is greater than the width of the opening 31a of the crosspiece member 31. Therefore, by tilting the attachment portion 235, the bottom wall portion 251 can be inserted from the opening 31a.

[0125] Next, as shown in FIG. 20(c), the worker accommodates the entire bottom wall portion 251 in the accommodation space 31k, and then rotates the mounting portion 235 around the Y axis to return it to its original position. Then, the mounting portion 235 is placed on the second protruding portions 31h, 31h of the crosspiece member 31. At this time, the bottom wall portion 251 is placed across the second protruding portions 31h, 31h. In this manner, the second protruding portions 31h, 31h have a placement surface on which the mounting portion 235 can be placed.

[0126] Next, the worker places the solar panel P between the temporarily placed mounting portion 235 and the crosspiece member 31. Specifically, the solar panel P is placed between the extension portion 32-5 of the first mounting portion 132 and the mounting surface 31p of the crosspiece member 31.

[0127] Finally, the worker tightens the bolts 38 of the mounting portions 235 to secure the solar panel P to the crosspiece members 31.

[0128] This completes the work of installing the mounting frame 1 and the solar panel P on the roof surface of the building.

[0129] 19, a cross-piece member cap 260 may be attached to the end of the cross-piece member 31, and a mounting member cap 270 may be attached to the mounting portion 235. The cross-piece member cap 260 is a cap having a recess 261 formed therein that matches the outer shape of the cross-piece member 31. The cross-piece member cap 260 is attached by fitting the end of the cross-piece member 31 into the recess 261 of the cross-piece member cap 260. The mounting member cap 270 is also formed with a snap fit 271 that engages with the protruding plate portion 32-6. The mounting member cap 270 is attached to the mounting portion 235 by fitting the snap fit 271 into the protruding plate portion 32-6.

[0130] According to the mount 301 of the fourth embodiment, the mounting portion 235 for mounting the solar panel P to the crosspiece member 31 has the second mounting portion 250 placed on the crosspiece member 31, and the first mounting portion 132 that sandwiches the solar panel P between the crosspiece member 31 and is combined with the solar panel P so as to be slidable in a direction to press the solar panel P. This makes it possible for the second mounting portion 250 to prevent the first mounting portion 132 from falling over, and to stabilize the posture of the mounting portion 235 placed on the crosspiece member 31. In this way, stabilizing the mounting portion 235 makes it easier to mount the solar panel P, and improves the efficiency of the panel mounting work.

[0131] 20(c), the second mounting portion 250 is provided with a bottom wall portion 251 that is placed across the second protruding portion 31h of the crosspiece member 31. The length of contact between the second protruding portion 31h and the bottom wall portion 251 can be set to any length, and a sufficient length that can stabilize the posture of the mounting portion 235 can be ensured.

[0132] Moreover, the first mounting portion 132 and the second mounting portion 250 are combined to be slidable in a direction parallel to the pressing direction of the solar panel P by sliding the protruding plate portion 32-6 formed on the first mounting portion 132 over the slide surface 250a, which is the end face of the second mounting portion 250. This allows the axial force introduced into the bolt 38 to be smoothly transmitted to the first mounting portion 132, and the solar panel P can be clamped between the first mounting portion 132 and the crosspiece member 31.

[0133] 20(d), the second mounting portion 250 is formed with third convex locking portions 251c, 251c that fit into the grooves 31i, 31i formed in the crosspiece member 31. This allows the mounting portion 235 to be stably mounted to the crosspiece member 31.

[0134] Further, the second mounting portion 250 is formed with a support portion 252 that comes into contact with the surface of the solar panel P facing the -Z side. This allows the support portion 252 to be caught by the solar panel P, preventing the mounting portion 235 from falling over. This improves the efficiency of the panel mounting work.

[0135] This invention is not limited to the above-mentioned embodiment, and various modifications and applications are possible. In the above-mentioned embodiments 1 to 3, the plate-shaped protruding plate portion 32-6 is shown as the insertion portion formed in the first mounting portion 32, 132, but the shape of the insertion portion is arbitrary. For example, the insertion portion may be a rod-shaped portion such as a cylinder or a rectangular column. In this case, the inserted portion formed in the second mounting portion 33, 133 may also be a shape that matches the insertion portion, such as a circular recess or a square recess.

[0136] In the above embodiment, the insert portion is formed in the first mounting portion 32, 132, and the inserted portion is formed in the second mounting portion 33, 133. However, it is arbitrary which mounting portion the insert portion and the inserted portion are formed in, and the insert portion may be formed in the second mounting portion 33, 133, and the inserted portion may be formed in the first mounting portion 32, 132.

[0137] Also, a case has been described in which a gap is provided between the second protrusions 31h, 31h in the crosspiece member 31, and the cable 2 of the solar panel P is accommodated through the gap. However, it is optional whether or not to provide a gap between the second protrusions 31h, 31h, and the crosspiece member 31 may be configured to divide the inside of the crosspiece member 31 like a partition wall without providing a gap.

[0138] Furthermore, when fixing the solar panel P to the crosspiece member, the mounting parts shown in the first to fourth embodiments can be used in combination. For example, the mounting part 235 shown in the fourth embodiment can be used as an intermediate mounting part that presses two solar panels P on both sides, and the mounting part 35 (35a) shown in the first embodiment can be used as an end mounting part that presses one solar panel P on only one side.

[0139] In the above embodiment, the rail member 31 is described as being fixed via the base portion 70 shown in FIG. 1, but the fixing method of the rail member 31 is arbitrary, and the fixing method can be selected according to the mounting location of the frame.

[0140] In the above embodiment, the mount is described as a mount for fixing the solar panel. However, the present invention is not limited to this. The mount may support an object installed on the roof of a house other than the solar panel. For example, the mount may support a panel for a water heater. The mount can support any panel with a frame.

[0141] In the above embodiment, the case where the mount is attached to the roof surface R of the building has been described. However, the mount may be installed anywhere. For example, the mount may be installed on the roof of the building or on the ground. Furthermore, the panels may be oriented in various directions depending on the function of the panels, and may be arranged facing upward, for example.

[0142] 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]
