[0012] Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiment, an example in which the present invention is applied to a mounting fixture for mounting a solar panel to a folded plate roof will be described. Note that the following description is an example, and the present invention is not limited to the following content.

[0013] FIG. 1 is a diagram showing a state in which a solar power generation panel is attached to a folded plate roof 100 by a mounting fixture according to an embodiment. The folded plate roof 100 shown in FIG. 1 is formed by folding and connecting a plurality of plates by sheet metal processing. The folded plate roof 100 has a plurality of upright seam portions 101 formed by the connection portions of the metal sheets. The folded plate roof 100 according to this example is a so-called vertical roof, and the seam portion 101 extends along the slope (flow direction) of the folded plate roof 100. However, the folded plate roof 100 is not limited to vertical roofing, and may be horizontal roofing. The mounting fixtures 10, 20 are fixed to the seam portion 101, and the solar power generation panel P1 is fixed to the mounting fixtures 10, 20, so that the solar power generation panel P1 is attached to the folded plate roof 100.

[0014] [Solar power generation panels] The solar power generation panel P1 is an example of a "panel" according to the present invention. The solar power generation panel P1 according to the embodiment is formed in a substantially rectangular plate shape and is installed in a lying position on the folded-plate roof 100. Here, the "lower surface" of the solar power generation panel P1 refers to the surface facing the folded-plate roof 100 when the solar power generation panel P1 is installed on the folded-plate roof 100. In addition, the "upper surface" of the solar power generation panel P1 refers to the surface opposite the folded-plate roof 100 when the solar power generation panel P1 is installed on the folded-plate roof 100. The solar power generation panel P1 is configured to receive light on its upper surface and generate power. As shown in FIG. 1, in this example, two solar power generation panels P1 are arranged side by side in the extension direction of the seam portion 101. The solar power generation panels P1 are each attached in a state of being spanned across two seam portions 101. However, the number of the solar power generation panels P1 and the number of the seam portions 101 are not limited to this.

[0015] [Mounting fixture] The mounting fixture 10 and the mounting fixture 20 are examples of the "mounting fixture" according to the present invention. The mounting fixture 10 is a middle clamp, and is used to fix opposing edges of a plurality of photovoltaic power generation panels P1 arranged side by side in the extension direction of the seam portion 101 to the seam portion 101. The mounting fixture 20 is an end clamp, and is used to fix edges located at both ends in the extension direction of the seam portion 101 to the seam portion 101 of a plurality of photovoltaic power generation panels P1 arranged side by side in the extension direction of the seam portion 101.

[0016] The configurations of the mounting fixtures 10 and 20 will be described below. In the following description, the direction corresponding to the up-down direction when the mounting fixtures 10, 20 are fixed to the seam portion 101 is defined as the Z direction (up-down direction), the direction corresponding to the extension direction of the seam portion 101 is defined as the X direction (depth direction), and the direction corresponding to the width direction of the seam portion 101 is defined as the X direction (left-right direction). The Y direction is perpendicular to the Z direction, and the X direction is perpendicular to the Z and Y directions.

[0017] [Middle mounting bracket] First, the mounting fixture 10 will be described. Fig. 2 is a view seen in the X direction showing the state in which the solar power generation panel P1 is attached to the seam portion 101 by the mounting fixture 10. Fig. 3 is a view seen in the Y direction showing the state in which the solar power generation panel P1 is attached to the seam portion 101 by the mounting fixture 10. Fig. 4 is a view seen in the X direction showing the state before the mounting fixture 10 is fixed to the seam portion 101. Fig. 5 is an exploded perspective view of the mounting fixture 10.

[0018] As shown in Figs. 2 and 3, the mounting fixture 10 includes a pair of clamping members 1 and 2 that clamp the seam portion 101, a connector 3 that connects the pair of clamping members 1 and 2, and a clamping member 4 that presses the solar panel P1 from above. The mounting fixture 10 is attached to the seam portion 101 by clamping both sides of the seam portion 101 with the pair of clamping members 1 and 2. Here, the posture of the pair of clamping members 1 and 2 that can clamp the seam portion 101 as shown in Fig. 2 and the like is referred to as a "first posture." One (one side) of both sides of the seam portion 101 is referred to as a first side S1, and the other (the other side) is referred to as a second side S2. In addition, the direction from the second side S2 to the first side S1 in the Y direction is referred to as a first direction F1, and the opposite direction (i.e., the direction from the first side S1 to the second side S2) is referred to as a second direction F2.

[0019] [First clamping member] As shown in Figure 2 etc., the first clamping member 1, which is one of the pair of clamping members 1, 2, has a support portion 11 that supports the solar power generation panel P1 above the seam portion 101, a first abutment end portion 12 that is provided below the support portion 11 and abuts the first side surface S1 of the seam portion 101 from the first direction F1 side, a first connection portion 13 that connects the side end portion of the support portion 11 (more specifically, the main body portion 111) on the first direction F1 side and the first abutment end portion 12, and a guide portion 14 that protrudes downward from the side end portion of the support portion 11 (more specifically, the main body portion 111) on the second direction F2 side.

[0020] As shown in FIG. 2 and other figures, the support portion 11 has a main body portion 111, a pair of standing portions 112, 112, and a pair of mounting portions 113, 113. The main body portion 111 is a portion that is connected to the second clamping member 2 via the connector 3, and is formed in a rectangular plate shape that is perpendicular to the Z direction and elongated in the X direction. As shown in FIG. 5, the main body portion 111 has a through hole 11a that is a hole into which the shaft portion 311 of the connector 3 is inserted, penetrating in the Z direction. The through hole 11a is formed as a long hole that is elongated in the Y direction (left-right direction). The pair of standing portions 112, 112 are formed in a plate shape that extends upward from both side ends of the main body portion 111 in the Y direction. The pair of mounting portions 113, 113 are portions on which the solar power generation panel P1 is mounted, as shown in FIG. 2. The mounting portion 113 is provided at the upper end of the standing portion 112, and is formed in a plate shape that is perpendicular to the Z direction. A gap is formed between the pair of mounting portions 113, 113 so that the shaft portion 311 of the connector 3 can be inserted into the through hole 11a of the main body portion 111.

[0021] As shown in FIG. 2 and other figures, the first connection portion 13 is formed in a plate shape extending downward from the side end portion of the main body portion 111 on the first direction F1 side.

[0022] As shown in FIG. 2 and other figures, the first contact end 12 is formed in a plate shape extending in the second direction F2 from the lower end of the first connection portion 13, and its tip contacts the first side surface S1.

[0023] 2 and other drawings, the guide portion 14 is formed in a piece shape (plate shape) extending downward from a side end portion on the second direction F2 side of the main body portion 111. The guide portion 14 is inclined so as to protrude in the second direction F2 as it extends downward.

[0024] [Second clamping member] As shown in FIG. 2 and other figures, the second clamping member 2, which is the other of the pair of clamping members 1, 2, is disposed between the first connection portion 13 and the guide portion 14 in the first attitude, and is provided below the base portion 21 and facing the second direction F2 side. The base portion 21 has a second abutment end 22 that abuts against the second side surface S2 of the seam portion 101, and a second connection portion 23 that connects the side end of the base portion 21 on the second direction F2 side to the second abutment end 22.

[0025] As shown in Fig. 2 etc., the base portion 21 is a portion that is connected to the main body portion 111 of the first clamping member 1 via the connector 3, and is formed in a rectangular plate shape that is perpendicular to the Z direction and elongated in the X direction. As shown in Fig. 5, the base portion 21 has a through hole 21a that is a hole into which the shaft portion 311 of the connector 3 is inserted, penetrating in the Z direction. In addition, as shown in Fig. 2 etc., a restricting portion 21b is formed on the lower surface of the base portion 21.

[0026] As shown in FIG. 2 and other figures, the second connection part 23 is formed in a plate shape extending downward from the side end of the base part 21 on the second direction F2 side. The second connection part 23 has a slide part 231 continuing to the side end of the base part 21 on the second direction F2 side, and a convex finger hook part 232 arranged below the slide part 231 and protruding in the second direction F2. The slide part 231 is inclined so as to protrude in the second direction F2 as it goes downward so as to follow the guide part 14 in the first attitude. The guide part 14 is placed on the slide part 231 in the first attitude. The finger hook part 232 is a part for an operator to slide the second clamping member 2, and is formed in a rib shape extending along the X direction (depth direction). The finger hook part 232 extends over the entire area of ​​the second connection part 23 in the depth direction. The finger hook part 232 is not limited to a rib shape, and may be a columnar protrusion (small protrusion). In addition, as long as an operator can put his / her finger on the finger hook portion 232 and push the second clamping member 2 along the guide portion 14, the size and shape of the finger hook portion 232 are not particularly limited. As shown in FIG. 2, the finger hook portion 232 is provided so as to be located lower than the tip end of the guide portion 14 of the first clamping member 1 in the first position. Therefore, the finger hook portion 232 does not contact the guide portion 14 in the first position. As a result, a gap (interval) is formed between the guide portion 14 and the finger hook portion 232 in the first position. This gap is formed so that the operator's finger can enter the gap and contact the finger hook portion 232. As a result, the operator can put his / her finger on the finger hook portion 232 and slide the second clamping member 2.

[0027] As shown in FIG. 2 and other figures, the second contact end 22 is formed in a plate shape extending in the first direction F1 from the lower end of the second connection portion 23, and its tip contacts the second side surface S2.

[0028] As shown in FIG. 2 and other figures, in the first position, the second clamping member 2 is positioned at a predetermined position relative to the first clamping member 1 by the guide portion 14 and the slide portion 231 coming into contact with each other.

[0029] [Pinching member] 3, the clamping member 4 is attached to the shaft portion 311, and is a member that clamps the solar power generation panel P1 between itself and the support portion 11 by pressing down on the solar power generation panel P1 supported by the support portion 11 from above. The clamping member 4 is for a middle use, and presses down from above the opposing edge portions of two solar power generation panels P1 adjacent to each other in the extension direction (X direction) of the seam portion 101. The clamping member 4 includes an attachment portion 41, a pair of upright portions 42, 42, and a pressing portion 43.

[0030] The mounting portion 41 is a portion that is connected to the main body portion 111 of the first clamping member 1 via the connector 3, and is formed in a rectangular plate shape that is perpendicular to the Z direction and elongated in the Y direction. As shown in FIG. 5, the mounting portion 41 has a through hole 41a that is a hole into which the shaft portion 311 of the connector 3 is inserted, penetrating in the Z direction. The pair of standing portions 42, 42 are formed in a plate shape that extends upward from both side ends of the main body portion 111 in the X direction. As shown in FIG. 3, the standing portion 42 abuts against the side edge of the solar power generation panel P1 from the X direction, thereby restricting the positional deviation of the solar power generation panel P1 in the X direction. The pair of pressing portions 43, 43 are portions that press the solar power generation panel P1 from above, as shown in FIG. 3. The pressing portion 43 is provided at the upper end of the standing portion 42, and is formed in a rectangular plate shape that is elongated in the Z direction. The clamping member 4 is formed in a plate shape perpendicular to the direction of the clamping member 4. A gap is formed between the pair of pressing portions 43, 43 so that the shaft portion 311 of the connector 3 can be inserted into the through hole 41a of the mounting portion 41. The pressing portion 43 presses the edge portion of the solar power generation panel P1 from above, whereby the solar power generation panel P1 is clamped between the pressing portion 43 of the clamping member 4 and the placement portion 113 of the support portion 11.

[0031] [Connector] As shown in FIGS. 4 and 5, the connector 3 includes a fastening member 30, a coil spring 33 (biasing member), a washer 34, and a nut member 35.

[0032] The fastening member 30 is a member capable of fastening the support portion 11 of the first clamping member 1 and the base portion 21 of the second clamping member 2. The fastening member 30 has a bolt member 31 and a nut member 32 (a lower fastening portion). The mounting fixture 10 can be in a fastened state in which the support portion 11 and the base portion 21 are fastened by the fastening member 30 as shown in Fig. 2, or in a released state in which the fastened state is released as shown in Fig. 4.

[0033] 5, the bolt member 31 includes a shaft portion 311 having a thread groove formed on its outer circumferential surface and a head portion 312 (upper fastening portion) formed at one end of the shaft portion 311 with a larger diameter than the shaft portion 311, and is an integrally formed member. The bolt member 31 in this example is a so-called hexagonal bolt, and the outer shape of the cross section of the head portion 312 is formed into a hexagonal shape. However, the bolt member 31 does not have to be a hexagonal bolt.

[0034] As shown in Fig. 2 etc., the nut member 32 is a member that engages with the shaft portion 311 of the bolt member 31. A thread groove is formed on the inner peripheral surface of the nut member 32, and the thread groove of the nut member 32 and the thread of the shaft portion 311 of the bolt member 31 engage with each other, thereby engaging the nut member 32 with the shaft portion 311. The nut member 32 of this example is a so-called hexagonal nut, and the outer shape of the cross section is formed into a hexagon. However, the nut member 32 does not have to be a hexagonal nut.

[0035] In the mounting tool 10, the dimensions of the through hole 11a, the through hole 21a, the shaft 311, and the head 312 are set so that the shaft 311 can be inserted into the through hole 11a and the through hole 21a, the head 312 cannot be inserted into the through hole 21a, and the nut member 32 cannot be inserted into the through hole 11a. As shown in FIG. 5, in the mounting tool 10, the shaft 311 is inserted into the through hole 11a and the through hole 21a so that the head 312 is located below the base portion 21, so that the shaft 311 penetrates the support portion 11 and the base portion 21 in the vertical direction. In other words, the shaft 311 protrudes upward from the base portion 21 and penetrates the support portion 11 in the vertical direction. Then, as shown in FIG. 2, the nut member 32 is engaged with a portion of the shaft 311 that is above the main body portion 111 and below the mounting portion 41. As a result, the support portion 11 and the base portion 21 are sandwiched from above and below by the nut member 32 and the head portion 312. That is, the nut member 32 (upper fastening portion) is provided on the shaft portion 311 so as to sandwich the support portion 11 between the base portion 21 and the nut member 32 (upper fastening portion) from above and below. Here, as shown in FIG. 2, the restricting portion 21b of the base portion 21 engages with the head portion 312, so that the rotation of the bolt member 31 around the shaft portion 311 is restricted. As a result, the nut member 32 rotates around the shaft portion 311 by merely rotating the nut member 32 around the shaft portion 311 without the operator having to hold the bolt member 31 by hand. As a result, the nut member 32 and the head portion 312 rotate relatively around the shaft portion 311, and the nut member 32 moves along the shaft portion 311. As a result, the distance between the nut member 32 and the head portion 312 in the axial direction of the shaft portion 311 can be changed. That is, the distance between the nut member 32 and the base portion 21 can be changed.

[0036] By changing the distance between the nut member 32 and the head 312 (and thus the base portion 21), the mounting tool 10 can be switched between a fastened state and a released state. As shown in FIG. 2, the nut member 32 (upper fastening portion) and the head 312 (lower fastening portion) fasten the support portion 11 and the base portion 21 together. The fastening tool 10 is in a fastened state by the support part 11 being clamped between the nut member 32 (upper fastening part) and the base part 21. In the fastened state, it can be said that the support part 11 is clamped between the nut member 32 (upper fastening part) and the base part 21. Also, as shown in FIG. 4, the fastening tool 10 is in a released state by the nut member 32 and the head part 312 (and thus the base part 21) being spaced apart from each other more than in the fastened state. Note that the fastening tool 10 may be in a form in which the base part 21 and the shaft part 311 are integrated without the bolt member 31, and the shaft part 311 protrudes upward from the base part 21. In this example, the nut member 32 is an example of an "upper fastening member", and the head part 312 is an example of a "lower fastening member".

[0037] 4, the coil spring 33 is a compression spring provided between the support part 11 and the nut member 32, and is formed of a spirally wound wire. The coil spring 33 is attached to the shaft part 311 between the main body part 111 of the support part 11 and the nut member 32. Therefore, the axial direction of the coil spring 33 and the axial direction of the shaft part 311 are parallel to each other.

[0038] Here, Fig. 6 shows coil spring 33, Fig. 6(a) is a side view of coil spring 33, and Fig. 6(b) is an axial view of the expansion and contraction portion of coil spring 33. As shown in Fig. 6(a), coil spring 33 includes bottom portion 33a, top portion 33b, and expansion and contraction portion 331. Bottom portion 33a is an end turn that forms the lower end of coil spring 33. Top portion 33b is an end turn that forms the upper end of coil spring 33. Expansion portion 331 connects bottom portion 33a and top portion 33b, and is a portion that expands and contracts in the axial direction under load.

[0039] As shown in Fig. 6(a), the coil spring 33 is formed as a so-called tapered spring in which the wire is wound so as to gradually reduce in diameter from the bottom 33a to the top 33b. Here, as shown in Fig. 6(b), the wire in the expandable portion 331 that expands and contracts in the coil spring 33 forms a spiral shape when viewed in the axial direction. That is, the wire in the expandable portion 331 is wound so as to gradually reduce in diameter along the axial direction of the bolt member 31 so that the wire does not overlap in the axial direction.

[0040] The coil spring 33 is provided between the support portion 11 and the nut member 32 so that in the released state shown in FIG. 4, the coil spring 33 is contracted from its natural length and extended from its fully compressed state (most contracted state). As a result, in the released state, the nut member 32 is urged upward by the coil spring 33. By urging the nut member 32 upward, the head portion 312 connected to the nut member 32 via the shaft portion 311 is also urged upward. As a result, the head portion 312 presses the base portion 21 against the main body portion 111 of the support portion 11, and the relative movement of the first clamping member 1 and the second clamping member 2 is suppressed. In other words, the coil spring 33 presses the base portion 21 against the support portion 11. Therefore, in the released state, the first posture of the pair of clamping members 1 and 2 is maintained by the urging force of the coil spring 33. The coil spring 3 3 is an example of a "biasing member."

[0041] The washer 34 is an annular member attached to the shaft portion 311 between the coil spring 33 and the nut member 32. Therefore, the axial direction of the washer 34 and the shaft portion 311 are parallel to each other. FIG. 7 is a cross-sectional view showing the state of the coil spring 33 and the washer 34. As shown in FIG. 7, the washer 34 is placed on the coil spring 33 in a state in which the axis of the coil spring 33 and the axis of the washer 34 coincide with each other (i.e., in a centered state). Here, the washer 34 is a so-called cone washer, and is formed in a ring shape inclined upward from the outer peripheral edge 34a toward the inner peripheral edge 34b as shown in FIG. 7. Therefore, lateral displacement between the washer 34 and the washer 34 is suppressed, and a centered state is maintained between the axis of the coil spring 33 and the axis of the washer 34.

[0042] As shown in FIG. 3 and other figures, the nut member 35 is engaged with the shaft portion 311 of the bolt member 31. and is a member that fixes the clamping member 4. The nut member 35 fastens the mounting portion 41 by engaging with a portion of the shaft portion 311 that is above the mounting portion 41. As a result, the clamping member 4 is fixed in place with the pressing portion 43 pressing against the solar power generation panel P1.

[0043] [End fittings] Next, the mounting fixture 20 will be described. Fig. 8 is a view seen in the X direction showing the state in which the solar power generation panel P1 is attached to the seam portion 101 by the mounting fixture 20. Fig. 9 is a view seen in the Y direction showing the state in which the solar power generation panel P1 is attached to the seam portion 101 by the mounting fixture 20. Fig. 10 is an exploded perspective view of the mounting fixture 20. As shown in Figs. 8 to 10, the end mounting fixture 20 differs from the middle mounting fixture 10 in that it includes a clamping member 5 instead of the clamping member 4, but is generally similar to the mounting fixture 10 in other respects. Therefore, the description will focus on the clamping member 5, and the same components as those of the mounting fixture 10 will be denoted by the same reference numerals and detailed description will be omitted.

[0044] 9, the clamping member 5 is an end member that presses down from above the edges located at both ends in the extension direction of the seam portion 101 of a plurality of photovoltaic panels P1 arranged side by side in the extension direction (X direction) of the seam portion 101. The clamping member 5 includes an attachment portion 51, an upright portion 52, and a pressing portion 53.

[0045] The mounting portion 51 is a portion that is connected to the main body portion 111 of the first clamping member 1 via the connector 3, and is formed in a rectangular plate shape that is perpendicular to the Z direction and elongated in the Y direction. As shown in FIG. 10, the mounting portion 51 has a through hole 51a that is a hole into which the shaft portion 311 of the connector 3 is inserted, penetrating in the Z direction. The standing portion 52 is formed in a plate shape that extends upward from one side end of the main body portion 111 in the X direction. As shown in FIG. 9, the standing portion 52 abuts against the side edge of the solar power generation panel P1 from the X direction, thereby restricting the positional deviation of the solar power generation panel P1 in the X direction. The pressing portion 53 is a portion that presses the solar power generation panel P1 from above, as shown in FIG. 9. The pressing portion 53 is provided at the upper end of the standing portion 52, and is formed in a plate shape that is perpendicular to the Z direction. The pressing portion 53 presses the edge portion of the solar panel P1 from above, whereby the solar panel P1 is clamped between the pressing portion 53 of the clamping member 5 and the placement portion 113 of the support portion 11.

[0046] [Panel installation method] 11 to 15 are diagrams for explaining a method for fixing the mounting tool 10 to the seam portion 101. Reference symbol H1 in the drawings indicates the hand of an operator. Hereinafter, a method for mounting the solar power generation panel P1 to the seam portion 101 will be described with reference to the drawings.

[0047] First, the mounting tool 10 is prepared as shown in Fig. 11. The mounting tool 10 according to the embodiment is shipped in a released state in which fastening by the fastening members 30 is released as shown in Fig. 11, and the clamping member 5 and the nut member 35 are not yet attached. As described above, in the released state, the nut member 32 is urged upward by the coil spring 33, causing the head 312 to press the base portion 21 against the support portion 11, thereby maintaining the first posture of the pair of clamping members 1, 2.

[0048] Next, as shown in FIG. 12, when an operator, while gripping the first clamping member 1, hooks his / her finger on the finger hook portion 232 of the second clamping member 2 and pushes the second clamping member 2 downward against the biasing force of the coil spring 33, the base portion 21 separates from the support portion 11. As a result, the first abutment end 12 and the second abutment end 22 separate from each other, and the seam portion 101 can be received between the first abutment end 12 and the second abutment end 22. Here, the position of the pair of clamping members 1, 2 in which the seam portion 101 can be received between the first abutment end 12 and the second abutment end 22 as shown in FIG. 12 is referred to as the "second position." At this time, when the pair of clamping members 1, 2 are in the first position shown in FIG. 11, 12, the slide portion 231 of the second clamping member 2 slides along the guide portion 14 of the first clamping member 1, thereby guiding the movement of the second clamping member 2. Since the guide portion 14 is inclined so as to protrude toward the second direction F2 as it moves downward, and the slide portion 231 is inclined so as to follow the guide portion 14, the second clamping member 2 moves toward the second direction F2 as it moves downward. In other words, the second clamping member 2 moves obliquely downward. As a result, the second abutting end 22 moves away from the first abutting end 12 toward the second direction F2, and a gap in the Y direction (the width direction of the seam portion 101) is secured between the first abutting end 12 and the second abutting end 22. This makes it easier for the seam portion 101 to be received between the first abutting end 12 and the second abutting end 22.

[0049] Next, as shown in Figure 13, the operator pushes the second clamping member 2 downward and maintains the second position, while the seam portion 101 is received between the first abutment end 12 and the second abutment end 22.

[0050] Next, as shown in FIG. 14, when the worker releases the downward pressing of the second clamping member 2 with the seam portion 101 received between the first abutting end 12 and the second abutting end 22, the head 312 presses the base portion 21 against the support portion 11 again due to the biasing force of the nut member 32, and the pair of clamping members 1 and 2 reach the first position from the second position. As a result, the first abutting end 12 of the first clamping member 1 abuts against the first side surface S1 of the seam portion 101, and the second abutting end 22 of the second clamping member 2 abuts against the second side surface S2 of the seam portion 101, and the seam portion 101 is clamped between the pair of clamping members 1 and 2. As a result, the mounting tool 10 is provisionally fixed to the seam portion 101. Then, the first position of the pair of clamping members 1 and 2 is maintained by the biasing force of the coil spring 33, so that the state in which the seam portion 101 is clamped between the pair of clamping members 1 and 2 is also maintained.

[0051] When the pair of clamping members 1, 2 move from the second position to the first position, the slide portion 231 of the second clamping member 2 slides along the guide portion 14 of the first clamping member 1, thereby guiding the second clamping member 2 to a predetermined position.

[0052] Next, an operator rotates the nut member 32 around the shaft portion 311 using a tool such as a wrench, thereby shortening the distance between the nut member 32 and the head portion 312. Then, as shown in FIG. 15, the support portion 11 and the base portion 21 are clamped between the nut member 32 and the head portion 312, that is, the support portion 11 is clamped between the nut member 32 and the base portion 21, and the mounting tool 10 is in a fastened state. When the mounting tool 10 is in a fastened state, the relative movement between the first clamping member 1 and the second clamping member 2 is restricted, and the pair of clamping members 1 and 2 are fixed in the first position. As a result, the mounting tool 10 is fixed to the seam portion 101.

[0053] Here, Fig. 16 is a cross-sectional view that shows a schematic state of the coil spring 33 and the washer 34 in the fastened state of the mounting tool 10. As shown in Fig. 16, in the fastened state, the elastic force of the compressed coil spring 33 acts on the nut member 32 via the washer 34, increasing the frictional force between the nut member 32 and the washer 34, making it difficult for the nut member 32 to loosen. In other words, the combination of the coil spring 33 and the washer 34 functions as a loosening prevention device like a so-called spring washer.

[0054] After the fastener 10 is fixed to the seam portion 101, the fastener 20 is fixed to the seam portion 101. The fastener 20 may be fixed before the fastener 10. The end fastener 20 can be fixed to the seam portion 101 in the same manner as the middle fastener 10, so a description of the fixing method will be omitted.

[0055] After the mounting fixture 10 and the mounting fixture 20 are fixed to the seam portion 101, the photovoltaic power generation panel P1 is fixed to the mounting fixture 10 and the mounting fixture 20 using the clamping members 4 and 5. First, in the mounting fixture 10, as shown in FIG. 2 and 3, the photovoltaic panel P1 is placed on the placement portion 113 of the support portion 11, and the clamping member 4 is attached to the connector 3, whereby the photovoltaic panel P1 is pressed from above by the pressing portion 43 of the clamping member 4. As a result, the photovoltaic panel P1 is clamped between the main body portion 111 of the support portion 11 and the pressing portion 43 of the clamping member 4, and the photovoltaic panel P1 is fixed to the mounting fixture 10. Similarly, in the mounting fixture 20, as shown in FIGS. 8 and 9, the photovoltaic panel P1 is clamped between the main body portion 111 of the support portion 11 and the pressing portion 53 of the clamping member 5, and the photovoltaic panel P1 is fixed to the mounting fixture 20. In this manner, the photovoltaic panel P1 is attached to the seam portion 101.

[0056] [Actions and Effects] As described above, in this embodiment, in a fastened state in which the support portion 11 and the base portion 21 are fastened by the fastening member 30, the pair of clamping members 1, 2 are fixed in a first position in which the seam portion 101 can be clamped between the first abutment end portion 12 and the second abutment end portion 22. Furthermore, in a released state in which the fastened state is released, the base portion 21 is pressed against the support portion 11 by the biasing force of the coil spring 33 so that the first position of the pair of clamping members 1, 2 is maintained. Then, when the second clamping member 2 is pushed downward against the biasing force of the coil spring 33, the pair of clamping members 1, 2 assume a second position in which the seam portion 101 can be received between the first abutment end portion 12 and the second abutment end portion 22.

[0057] According to this, in a state where the nut member 32 is pushed downward to put the pair of clamping members 1, 2 in the second position and the seam portion 101 is received between the first abutting end 12 and the second abutting end 22, the downward pushing of the second clamping member 2 is simply released, and the pair of clamping members 1, 2 reach the first position from the second position by the biasing force of the coil spring 33, and the seam portion 101 is clamped by the pair of clamping members 1, 2. And, since the first position of the pair of clamping members 1, 2 is maintained by the biasing force of the coil spring 33, the seam portion 101 is also maintained in the state where it is clamped by the pair of clamping members 1, 2. According to this, the operation of changing the pair of clamping members 1, 2 from the second position to the first position and the operation of maintaining the first position are performed by the biasing force of the coil spring 33, so the burden of performing these operations by the worker's hands is reduced. As a result, the work of installing the solar power generation panel P1 on the folded plate roof 100 can be facilitated. Furthermore, because the pair of clamping members 1, 2 are maintained in the first position by the biasing force of coil spring 33 even in the released state, there is no risk of disassembly or parts rattling even if the fastening state is not established during shipping or transportation of mounting fixture 10 and mounting fixture 20. Furthermore, if mounting fixture 10 and mounting fixture 20 are maintained in the fastening state during shipping or transportation, work must be done to release the pair of clamping members 1, 2 once to put them in the second position when they are attached to seam portion 101; however, by setting mounting fixture 10 and mounting fixture 20 in the released state in advance, the above work can be omitted.

[0058] Furthermore, the first clamping member 1 has a guide portion 14 protruding downward from the support portion 11, and the second connection portion 23 of the second clamping member 2 has a sliding portion 231 that slides along the guide portion 14 as the pair of clamping members 1, 2 move from the first position to the second position.

[0059] According to this, in the process in which the pair of clamping members 1, 2 move from the first posture to the second posture, the slide portion 231 slides along the guide portion 14 to guide the movement of the second clamping member 2, so that the transition to the second posture can be performed smoothly and reliably. In addition, the guide portion 14 is inclined so as to protrude toward the second direction F2 as it moves downward, and the slide portion 231 is inclined along the guide portion 14 to ensure a gap in the Y direction (width direction of the seam portion 101) between the first abutting end portion 12 and the second abutting end portion 22, so that the seam portion 101 can be easily received between the first abutting end portion 12 and the second abutting end portion 22. In addition, in the process in which the pair of clamping members 1, 2 move from the first posture to the first posture, the slide portion 231 slides along the guide portion 14 to guide the second clamping member 2 to a predetermined position. According to this, in the process in which the pair of clamping members 1, 2 move from the second posture to the first posture, the slide portion 231 slides along the guide portion 14 to guide the second clamping member 2 to a predetermined position. Since the second clamping member 2 is guided to a predetermined position during the process of reaching the first position, the transition to the first position can be performed smoothly and reliably.

[0060] Furthermore, the second clamping member 2 has a convex finger hook portion 232 that is provided to be located below the guide portion 14 in the first position so that the worker can slide the second clamping member 2. This allows the worker to contact (put his / her finger on) the finger hook portion 232 of the second clamping member 2, making it easier to push the second clamping member 2 downward against the biasing force of the coil spring 33. This makes it easier to change the pair of clamping members 1, 2 from the first position to the second position, improving workability. As a result, the work of installing the solar power generation panel P1 on the folded-plate roof 100 can be made easier.

[0061] Moreover, since the operator can hook the fingers of the hand gripping the first clamping member 1 on the finger hook portion 232, the operator can temporarily fix the attachment to the seam portion 101 (clamping the seam portion 101 with the pair of clamping members 1, 2) with one hand. Moreover, in this embodiment, the finger hook portion 232 is formed in a rib shape extending along the X direction (depth direction), so that the operator's fingers can easily hook onto the finger hook portion 232. As a result, the workability is further improved.

[0062] When changing from the first position to the second position, the nut member 32 may be pushed downward against the biasing force of the coil spring 33 while holding the first clamping member 1, thereby releasing the pressing of the base portion 21 by the head 312. This causes the base portion 21 to separate from the support portion 11, and the pair of clamping members 1 and 2 to transition to the second position.

[0063] Furthermore, in this embodiment, the bolt member 31 including the shaft portion 311 and the head portion 312 and the nut member 32 engaged with the shaft portion 311 are used to connect the pair of clamping members 1 and 2, and the nut member 32 is provided on the upper side and the head portion 312 is provided on the lower side, and is configured to clamp the support portion 11 and the base portion 21 from above and below. According to this, in assembling the mounting tool 10 and the mounting tool 20, the nut member 32 is attached from above to the shaft portion 311 in a state in which it is penetrated by the pair of clamping members 1 and 2, and a tightening operation is performed. Therefore, assembling the mounting tool 10 and the mounting tool 20 can be made easier than when the nut member 32 is attached from below. However, the present invention is not limited to the aspect in which the nut member 32 is provided on the upper side and the head portion 312 of the bolt member 31 is provided on the lower side. FIG. 17 is a diagram showing a mounting tool 10A according to a first modified example of the embodiment. As in the mounting tool 10A shown in Fig. 17, the nut member 32 may be provided on the lower side and the head portion 312 on the upper side, so that the support portion 11 and the base portion 21 are sandwiched from above and below. In the example shown in Fig. 17, the nut member 32 corresponds to the "lower fastening member", and the head portion 312 of the bolt member 31 corresponds to the "upper fastening member".

[0064] In this embodiment, the wire of the expandable portion 331 of the coil spring 33 that expands and contracts in the axial direction of the shaft portion 311 is wound so as to gradually reduce in diameter along the axial direction so that the wire does not overlap in the axial direction of the shaft portion 311. As a result, even if the expandable portion 331 is compressed in the fastened state as shown in FIG. 16, the wire does not overlap, so that the lateral displacement of the coil spring 33 is suppressed. As a result, the posture of the coil spring 33 is stable in the fastened state, and the nut member 32 is less likely to loosen. In addition, the wire of the expandable portion 331 is wound so as to reduce in diameter as it moves from the lower side to the upper side along the axial direction of the shaft portion 311. This stabilizes the posture of the coil spring 33. Note that the urging member according to the present invention is not limited to a coil spring.

[0065] The connector 3 according to this embodiment further includes a washer 34 attached to the shaft portion 311 between the coil spring 33 and the nut member 32, and the washer 34 is formed in an annular shape that is inclined upward from the outer peripheral edge 34a toward the inner peripheral edge 34b. This provides an anti-loosening effect similar to that of a washer. In addition, since the washer 34 is tapered, lateral displacement between the coil spring 33 and the washer 34 is suppressed, and the axis of the coil spring 33 and the axis of the washer 34 can be kept aligned. As a result, the nut member 32 can be made even more difficult to loosen. Note that the washer 34 is not an essential component of the present invention.

[0066] Furthermore, the mounting fixtures 10 and 20 according to this embodiment further include clamping members 4 and 5 that are attached to the shaft portion 311 and press down on the solar panel P1 supported by the support portion 11 from above to clamp the solar panel P1 between the support portion 11 and the clamping members 4 and 5. That is, in this embodiment, the solar panel P1 can be clamped using the shaft portion 311. Note that the clamping members 4 and 5 are not essential components of the present invention. For example, the solar panel P1 may be fastened to the main body portion 111 of the support portion 11 using a bolt member and a nut member.

[0067] Fig. 18 is a diagram showing a mounting tool 10B according to a second modified example of the embodiment. Fig. 18 shows a state in which a pair of clamping members 1, 2 are in a first position. The mounting tool 10B shown in Fig. 18 differs from the above-described mounting tool 10 in that a finger hook portion 232a that allows an operator to slide the second clamping member 2 is formed in a concave shape.

[0068] As shown in FIG. 18, the finger hook portion 232a is formed as a groove with a rectangular cross section that is recessed toward the first direction F1 and extends along the X direction (depth direction). However, the finger hook portion 232a is not limited to this. Furthermore, the finger hook portion 232a is provided so as to be located lower than the tip end of the guide portion 14 of the first clamping member 1 in the first position. Therefore, in the first position, the finger hook portion 232a is not covered by the guide portion 14, and the guide portion 14 is not received by the finger hook portion 232a. This allows the operator to slide the second clamping member 2 by hooking his / her finger on the finger hook portion 232a.

[0069] <Other> In the above embodiment, an example of attaching a solar panel to a folded-plate roof has been shown, but the panel to be attached is not limited to a solar panel, and may be any other device such as a power conditioner or solar hot water heater, as long as at least the portion supported by the mounting fixture is panel-shaped. For example, the panel may be a signboard, a display device, or a panel for fixing an outdoor unit of an air conditioner. [Explanation of symbols]
