[Figure 4] This is a perspective view of a support unit that is attached to a seam and supports a solar panel according to one embodiment of the present invention. [Modes for carrying out the invention]
[0009] One embodiment of the retaining member according to the present invention will be described with reference to the drawings. As shown in Figure 4, the support unit 1 is a component for supporting the solar panel 60 on the roof surface, and multiple units are arranged along the outer frame of the solar panel 60. More specifically, the support unit 1 comprises a mounting fixture 10 and a retaining member 70. The mounting device 10 is made of metal and is attached to the seam portion 80 of the folded-sheet metal roof. The mounting device 10 comprises a pair of clamping members 20, 30, a fastening portion 40, a mounting shaft portion 50, and an installation surface 21. The pair of clamping members 20 and 30 clamp the seam portion 80 from the width direction (the short side direction of the seam portion 80). The fastening portion 40 includes a bolt 40b and a nut 40n for fastening the pair of clamping members 20 and 30 while they are clamped to the seam portion 80.
[0010] As shown in Figures 1(a) and 1(b), the mounting surface 21 is formed on the upper surface of the mounting fixture 10, and the first frame portion 61 or the second frame portion 62 on the outer periphery of the solar panel can be installed there. The first frame portion 61 and the second frame portion 62 are frame portions with different heights (thicknesses). The height of the second frame portion 62 shown in Figure 1(b) is greater than the height of the first frame portion 61 shown in Figure 1(a).
[0011] The mounting shaft portion 50 is erected in the center of the installation surface 21. The mounting shaft portion 50 comprises a bolt 50b extending in the height direction and a nut 50n screwed onto the tip of the bolt 50b. The retaining member 70 is inserted through the bolt 50b and pressed against the frame portions 61, 62 of the solar panel and the installation surface 21 by the nut 50n.
[0012] Next, the configuration of the retaining member 70 will be described. As shown in Figures 2(a) and (b), the retaining member 70 is formed by an L-shaped plate-like metal fitting. The retaining member 70 comprises a first flat plate portion 71, a second flat plate portion 72, a connecting portion 79, a first inner wall portion 73, and a second inner wall portion 74. The first flat plate portion 71 is rectangular, and in this example, it is a rectangular plate. The second flat plate portion 72 is rectangular, in this example, a rectangular plate shape, and extends in a direction perpendicular to the first flat plate portion 71. As shown in Figure 3(c), the widthwise length H1 of the first flat plate portion 71 is longer than the widthwise length H2 of the second flat plate portion 72. In this example, length H1 is 35 mm and length H2 is 31 mm. The widthwise direction of the first flat plate portion 71 is the direction from the connecting portion 79 toward the tip portion 71a of the first flat plate portion 71, and the widthwise direction of the second flat plate portion 72 is the direction from the connecting portion 79 toward the tip portion 72a of the second flat plate portion 72. Furthermore, these widthwise directions are perpendicular to the longitudinal directions of the first flat plate portion 71 and the second flat plate portion 72.
[0013] The connecting portion 79 is the part that connects the base ends of the first flat plate portion 71 and the second flat plate portion 72 at a right angle. The connecting portion 79 extends in a direction that intersects the first flat plate portion 71 and the second flat plate portion 72. The connecting portion 79 forms an angle of approximately 45° with respect to the first flat plate portion 71 and the second flat plate portion 72. The thickness of the connecting portion 79 is formed to be greater than the thickness of the first flat plate portion 71 and the second flat plate portion 72.
[0014] As shown in Figure 2(a), the first flat plate portion 71 has a tip portion 71a, which is the end opposite to the connecting portion 79. The tip portion 71a is formed so that its thickness decreases as it moves away from the connecting portion 79. That is, an inclined surface is formed on the outer surface of the tip portion 71a (the upper surface in Figure 2(a)). As shown in Figure 1(a), in the first mounting position, the tip portion 71a presses against the upper surface of the first frame portion 61, and as shown in Figure 1(b), in the second mounting position, the tip portion 71a contacts the mounting surface 21 of the mounting fixture 10.
[0015] As shown in Figures 1(a) and 2(a), the first flat plate portion 71 has a bolt-through hole portion 71h through which a bolt 50b can pass. The bolt-through hole portion 71h is formed at the central position of the first flat plate portion 71 and has a circular hole that penetrates through the first flat plate portion 71 in the thickness direction.
[0016] As shown in Fig. 2(a), a first notation 75 and a first linear portion 76 are formed on the outer surface of the first flat plate portion 71. The first notation 75 is a notation corresponding to the height of the first frame portion 61 (see Fig. 1(a)). In this example, the first notation 75 is the notation "H31" which means a height of 31 mm. The first linear portion 76 extends linearly over the entire area of the outer surface of the first flat plate portion 71 along the longitudinal direction orthogonal to the width direction. The first linear portion 76 is located between the tip portion 71a and the bolt through-hole portion 71h. As shown in Fig. 3(d), the first linear portion 76 is formed as a V-groove. In this example, the angle α of this V-groove is set to 90°. As shown in Fig. 3(b), the first linear portion 76 functions as an alignment mark for the side surface 61a of the first frame portion 61 of the solar panel.
[0017] As shown in Fig. 1(a), the first inner wall portion 73 positions the solar panel in the plane direction by contacting the side surface 61a of the first frame portion 61. The first inner wall portion 73 stands on the inner surface of the first flat plate portion 71 and extends over the entire area of the inner surface of the first flat plate portion 71 along the longitudinal direction orthogonal to the width direction. As shown in Fig. 3(c), the first inner wall portion 73 includes a contact surface 73a and an inclined surface 73b. The contact surface 73a is located on the tip portion 71a side and is orthogonal to the inner surface of the first flat plate portion 71. The contact surface 73a is the surface that contacts the side surface 61a of the first frame portion 61 in the first mounting posture shown in Fig. 1(a). As shown in Fig. 3(c), the contact surface 73a is located directly behind the first linear portion 76 in the thickness direction of the first flat plate portion 71. In other words, the first linear portion 76 extends along the contact surface 73a of the first inner wall portion 73. The inclined surface 73b is the surface on the opposite side of the contact surface 73a and is inclined so as to move away from the contact surface 73a as it approaches the inner surface of the first flat plate portion 71.
[0018] As shown in Fig. 2(b), the second flat plate portion 72 includes a tip portion 72a that is an end portion on the side opposite to the connecting portion 79. The tip portion 72a is formed such that its thickness decreases as it moves away from the connecting portion 79. That is, an inclined surface is formed on the outer surface (the upper surface in Fig. 2(b)) of the tip portion 72a. As shown in Fig. 1(b), in the second mounting posture, the tip portion 72a presses the upper surface of the second frame portion 62, and as shown in Fig. 1(a), in the first mounting posture, the tip portion 72a contacts the installation surface 21 of the mounting tool 10.
[0019] As shown in Figs. 1(b) and 2(b), a bolt through hole portion 72h through which the bolt 50b can pass is formed in the second flat plate portion 72. The bolt through hole portion 72h is formed at the central position of the second flat plate portion 72 and has a circular hole penetrating in the thickness direction of the second flat plate portion 72.
[0020] As shown in Fig. 2(b), a second notation 77 and a second linear portion 78 are formed on the outer surface of the second flat plate portion 72. The second notation 77 is a notation corresponding to the height of the second frame portion 62 (see Fig. 1(b)). In this example, the second notation 77 is the notation "H35" meaning a height of 35 mm. As shown in Figs. 2(a) and (b), the first notation 75 and the second notation 77 are provided in opposite directions with the connecting portion 79 as the center. In this example, the lower sides of the first notation 75 and the second notation 77 are formed to face the connecting portion 79. Also, the first notation 75 and the second notation 77 are arranged on the same side as the bolt through hole portions 71h, 72h in the longitudinal direction. The second linear portion 78 extends linearly over the entire outer surface of the second flat plate portion 72 along the longitudinal direction orthogonal to the width direction. The second linear portion 78 is located between the tip portion 72a and the bolt through hole portion 72h. The second linear portion 78 is formed as a V-groove similarly to the first linear portion 76. As shown in Fig. 3(a), the second linear portion 78 functions as an alignment mark for the side surface 62a of the second frame portion 62 of the solar panel.
[0021] As shown in Figure 1(b), the second inner wall portion 74 positions the solar panel in the planar direction by contacting the side surface 62a of the second frame portion 62 in the second mounting position. The second inner wall portion 74 is erected on the inner surface of the second flat plate portion 72 and extends across the entire inner surface of the second flat plate portion 72 along the longitudinal direction perpendicular to the width direction. As shown in Figure 3(c), the second inner wall portion 74 comprises a contact surface 74a and an inclined surface 74b. The contact surface 74a is located on the tip portion 72a side and is perpendicular to the inner surface of the second flat plate portion 72. The contact surface 74a is the surface that contacts the side surface 62a of the second frame portion 62 in the second mounting position shown in Figure 1(b). As shown in Figure 3(c), the contact surface 74a is located directly behind the second linear portion 78 in the thickness direction of the second flat plate portion 72. In other words, the second linear portion 78 extends along the contact surface 74a of the second inner wall portion 74. The inclined surface 74b is the surface opposite to the contact surface 74a and is inclined to move away from the contact surface 74a as it approaches the inner surface of the second flat plate portion 72.
[0022] Next, we will explain how to use the retaining member 70. As shown in Figure 1(a), the retaining member 70 can switch between a first mounting position in which it holds down the first frame portion 61 and a second mounting position in which it holds down the second frame portion 62, as shown in Figure 1(b).
[0023] Here, we will first explain how to attach the retaining member 70 in the first mounting position. For example, as shown in Figure 1(a), when fixing the first frame portion 61 of the solar panel with the retaining member 70, the worker orients the retaining member 70 so that the first marking 75 corresponding to the first frame portion 61 is on the upper side, as shown in Figure 2(a). Then, as shown in Figure 1(a), the worker inserts a bolt 50b through the bolt passage hole 71h of the retaining member 70, aligns the upper corner of the first frame portion 61 with the tip 71a of the first flat plate portion 71 and the corner of the first inner wall portion 73, and brings the tip 72a of the second flat plate portion 72 into contact with the installation surface 21. At this time, as shown in Figure 3(b), the worker aligns the side surface 61a of the first frame portion 61 so that it is in a straight line with the first linear portion 76 of the first flat plate portion 71. Next, as shown in Figure 1(a), a nut 50n is inserted from the tip side (upper end side) of the bolt 50b, and the nut 50n is rotated to press the retaining member 70 against the first frame portion 61 and the installation surface 21. As a result, the first frame portion 61 is clamped between the tip portion 71a and the installation surface 21. This completes the installation of the retaining member 70 in the first mounting position. In this first mounting position, the first flat plate portion 71 has a height corresponding to the widthwise length H2 of the second flat plate portion 72, so it can hold down the first frame portion 61, which has the same height as length H2. Also, in the first mounting position, the bolt passage hole portion 72h through which the bolt 50b is not inserted functions as a ventilation opening.
[0024] Next, the method for attaching the retaining member 70 in the second mounting position will be described. For example, as shown in Figure 1(b), when fixing the second frame portion 62 of the solar panel with the retaining member 70, the worker orients the retaining member 70 so that the second marking 77 corresponding to the second frame portion 62 is on the upper side, as shown in Figure 2(b). Then, as shown in Figure 1(b), the worker inserts the bolt 50b through the bolt passage hole 72h of the retaining member 70, aligning the upper corner of the second frame portion 62 with the tip 72a of the second flat plate portion 72 and the corner of the second inner wall portion 74, and bringing the tip 71a of the first flat plate portion 71 into contact with the installation surface 21. At this time, as shown in Figure 3(a), the worker aligns the side surface 62a of the second frame portion 62 so that it is in a straight line with the second linear portion 78 of the second flat plate portion 72. Next, as shown in Figure 1(b), a nut 50n is inserted from the tip (upper end) side of the bolt 50b, and the nut 50n is rotated to press the retaining member 70 against the second frame portion 62 and the installation surface 21. As a result, the second frame portion 62 is clamped between the tip portion 72a and the installation surface 21. This completes the installation of the retaining member 70 in the second mounting position. In this second mounting position, the second flat plate portion 72 has a height corresponding to the widthwise length H1 of the first flat plate portion 71, so it can hold down the second frame portion 62, which has the same height as length H1. In addition, in the second mounting position, the bolt passage hole portion 71h through which the bolt 50b is not inserted functions as a ventilation opening. As described above, with a single pressing member 70, simply by changing the orientation of the pressing member 70, more specifically by rotating it so that the positional relationship between the first flat plate portion 71 and the second flat plate portion 72 is reversed, as shown in Figures 2(a) and (b), it is possible to press down on objects of two different heights (first frame portion 61 or second frame portion 62).
[0025] (effect) According to the embodiment described above, the following effects are achieved. (1) The retaining member 70 is attached to the mounting fixture 10 and holds down the frame portions 61 and 62 of the solar panel, which is an example of an object to be installed on the mounting surface 21 of the mounting fixture 10. The retaining member 70 comprises a first flat plate portion 71, a second flat plate portion 72 connected to the first flat plate portion 71 and extending in a direction intersecting the first flat plate portion 71, a first inner wall portion 73 erected on the inner surface of the first flat plate portion 71, and a second inner wall portion 74 erected on the inner surface of the second flat plate portion 72. The widthwise lengths H1 and H2 of the first flat plate portion 71 and the second flat plate portion 72 are formed to be different lengths from each other. The retaining member 70 is configured to allow switching between two mounting positions for the mounting fixture 10: a first mounting position in which the tip 72a of the second flat plate portion 72 is in contact with the mounting surface 21 and the tip 71a of the first flat plate portion 71 and the first inner wall portion 73 hold down the first frame portion 61, which is an example of a first object to be installed; and a second mounting position in which the tip 71a of the first flat plate portion 71 is in contact with the mounting surface 21 and the tip 72a of the second flat plate portion 72 and the second inner wall portion 74 hold down the second frame portion 62, which is an example of a second object to be installed. With this configuration, a single retaining member 70 can accommodate frame sections 61 and 62 of different heights. Therefore, there is no need to prepare a separate retaining member for each height of frame section 61 and 62, thereby increasing the versatility of the retaining member 70.
[0026] (2) The widthwise length H1 of the first flat plate portion 71 is longer than the widthwise length H2 of the second flat plate portion 72. In the first mounting position, the tip 72a of the second flat plate portion 72 contacts the mounting surface 21, the tip 71a of the first flat plate portion 71 contacts the upper surface of the first frame portion 61, and the first inner wall portion 73 contacts the side surface 61a of the first frame portion 61. In the second mounting position, the tip 71a of the first flat plate portion 71 contacts the mounting surface 21, the tip 72a of the second flat plate portion 72 contacts the upper surface of the second frame portion 62 which is higher than the first frame portion 61 in the height direction perpendicular to the mounting surface 21, and the second inner wall portion 74 contacts the side surface 62a of the second frame portion 62. A first marking 75 corresponding to the first frame portion 61 is formed on the outer surface of the first flat plate portion 71. A second notation 77 corresponding to the second frame portion 62 is formed on the outer surface of the second flat plate portion 72. With this configuration, when pressing down the first frame portion 61 with the pressing member 70, the pressing member 70 should be oriented so that the first marking 75 corresponding to the first frame portion 61 is on its upper surface, and when pressing down the second frame portion 62 with the pressing member 70, the pressing member 70 should be oriented so that the second marking 77 corresponding to the second frame portion 62 is on its upper surface. Thus, mistakes in mounting position between the first and second mounting positions are suppressed.
[0027] (3) The first notation 75 and the second notation 77 are provided in opposite directions to each other, centered on the connecting portion 79 of the first flat plate portion 71 and the second flat plate portion 72. With this configuration, the orientation of the first marking 75 and the second marking 77 can be the same in either the first mounting position or the second mounting position.
[0028] (4) A first linear portion 76 is formed on the outer surface of the first flat plate portion 71, extending in a longitudinal direction perpendicular to the width direction of the first flat plate portion 71. The first linear portion 76 is formed in the thickness direction of the first flat plate portion 71 at a position that coincides with a contact surface 73a, which is an example of a first contact surface that can contact the first frame portion 61 in the first mounting position of the first inner wall portion 73. A second linear portion 78 is formed on the outer surface of the second flat plate portion 72, extending in a longitudinal direction perpendicular to the width direction of the second flat plate portion 72. The second linear portion 78 is formed in the thickness direction of the second flat plate portion 72 at a position that coincides with a contact surface 74a, which is an example of a second contact surface that can contact the second frame portion 62 in the second mounting position of the second inner wall portion 74. With this configuration, when aligning the solar panel with the retaining member 70, the worker only needs to align it so that, when viewed from above, the first linear portion 76 or the second linear portion 78 is in a straight line with the side surfaces 61a and 62a of the frame portions 61 and 62 of the solar panel. This makes it easier to align the solar panel with the retaining member 70.
[0029] However, the present invention is not limited by the embodiments and drawings described above. Modifications (including the deletion of components) can be made as appropriate without altering the essence of the invention. An example of a modification is described below.
[0030] (modified version) In the above embodiment, the mounting device 10 was attached to the seam portion 80, but it is not limited to this and may be attached to other roof members or frame members other than the roof. The mounting device 10 supported the solar panel together with the retaining member 70, but it may also support structures other than solar panels.
[0031] In the above embodiment, the first notation 75 and the second notation 77 are not limited to numbers, but may be pictures or symbols. Furthermore, either the first notation 75 or the second notation 77 may be omitted. In the above embodiment, the first notation 75 and the second notation 77 were provided in a reversed orientation around the connecting portion 79, but they may also be provided in the same orientation without being reversed. In the above embodiment, the first linear portion 76 and the second linear portion 78 were in a straight line, but they may be in a dashed line or a dotted line. Furthermore, either the first linear portion 76 or the second linear portion 78 may be omitted. Also, both the first linear portion 76 and the second linear portion 78 may be omitted. Furthermore, in the above embodiment, the first linear portion 76 and the second linear portion 78 were formed as V-grooves, but they may be grooves of a shape other than V, or they may be formed in a convex shape rather than a groove. Moreover, the first linear portion 76 and the second linear portion 78 do not have to have irregularities as long as they are visible as lines to the operator, and may be formed with ink or the like.
