Description

[Technical Field]

[0001] The present invention relates to a mounting device for mounting one or more modules to a support member, and to a roof structure comprising the mounting device. [Background technology]

[0002] BACKGROUND ART Conventionally, in mounting fixtures for mounting modules (for example, solar panels) on a roof, a grounding member for electrically connecting modules to each other has been known (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-211011 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional fixtures have employed various techniques to secure the grounding member to the fixture body so that the grounding member does not rotate on the fixture body.

[0005] For example, in the invention described in Patent Document 1, guide pieces provided on the top of the mounting fixture body are used to secure the grounding member to the mounting fixture body. However, in mounting fixture bodies having such guide pieces, there is a problem in that the width between the guide pieces limits the size of the grounding member that can be used.

[0006] Another known technique is to use a groove on the top surface of the mounting fixture body to secure the grounding member to the mounting fixture body. However, providing a groove on the top surface of the mounting fixture body makes the top surface of the mounting fixture body thinner in parts, which can reduce the support strength for the module placed on the top surface of the mounting fixture body.

[0007] Another known technique is to fix the grounding member to the mounting fixture body by forming the grounding member so that it crosses the top surface of the mounting fixture body and covers the side surfaces of the mounting fixture body. However, in this case, the length of the grounding member (particularly the bending position of the grounding member) must be adjusted to match the length crossing the top surface of the mounting fixture body, which creates a problem in that the grounding members that can be used are limited by the size of the top surface of the mounting fixture body.

[0008] The present invention aims to provide a mounting fixture that can fix an earthing member to a mounting fixture body without thinning the upper surface of the mounting fixture body and without the usable earthing member being limited by the size of the earthing member and the size of the upper surface of the mounting fixture body, and a roof structure equipped with the mounting fixture. [Means for solving the problem]

[0009] In one aspect of the present invention, the mounting device of the present invention is a mounting device for mounting one or more modules to a support member, the mounting device comprising a mounting device main body and a plate arranged between the mounting device main body and the one or more modules, the mounting device main body having a structure at its lower part for fixing the mounting device main body to the support member, and a hole at its upper part through which a portion of a fixing means for fixing the one or more modules can be inserted, and the mounting device has an anti-rotation mechanism that prevents the plate from rotating relative to the hole when the plate is arranged at the upper part of the mounting device main body.

[0010] In one embodiment of the invention, the anti-rotation feature may include one or more tongues extending along at least a portion of a side of the hole, the one or more tongues extending from the plate.

[0011] In one embodiment of the invention, the one or more tongues may be configured to prevent rotation of the plate by contacting the sides of the hole.

[0012] In one embodiment of the invention, the hole may include one or more notches having a shape corresponding to the one or more tongues.

[0013] In one embodiment of the present invention, the hole has a cylindrical shape, and the one or more notches are formed in at least a portion of a side surface of the cylindrical shape, and the one or more notches may include two notches or four notches.

[0014] In one embodiment of the present invention, the hole may have the shape of a rectangular parallelepiped or a rectangular prism with a diamond-shaped base, and the one or more tongues may be configured to traverse at least one side of the rectangular parallelepiped or rectangular prism shape.

[0015] In one embodiment of the present invention, the one or more modules may include a plurality of photovoltaic modules, and the plate may include one or more protrusions for electrically connecting the plurality of photovoltaic modules.

[0016] In one aspect of the present invention, the roof structure of the present invention is a roof structure applied to a building, the roof structure comprising a roof of the building and the above-described mounting device for mounting one or more modules to the roof. [Effects of the Invention]

[0017] According to the present invention, it is possible to provide a mounting device that can fix an earthing member to a mounting device body without thinning the top surface of the mounting device body and without the earthing member that can be used being limited by the size of the earthing member and the size of the top surface of the mounting device body, and a roof structure that is equipped with this mounting device.

[Figure 2D] FIG. 10 is a perspective view showing another example of the rotation prevention mechanism 105 of the mounting device 100. DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0020] FIG. 1A is a perspective view showing an example of a mounting structure 10 of the present invention.

[0021] The mounting structure 10 includes a mounting fixture 100 and a support member 200. The mounting fixture 100 is used to mount one or more modules to the support member 200. The mounting fixture 100 has a structure at its bottom that can be fixed to the support member 200, and a structure at its top that can be used to fix one or more modules. This allows one or more modules to be mounted to the support member 200 via the mounting fixture 100.

[0022] The mounting fixture 100 includes a mounting fixture body 110a and a plate 120a disposed between the mounting fixture body 110a and one or more modules. In the embodiment shown in Figure 1A, the plate 120a is disposed on the top surface of the mounting fixture body 110a.

[0023] The mounting device body 110a has a structure at its bottom for fixing the mounting device body 110a to the support member 200. The structure for fixing the mounting device body 110a to the support member 200 can be, for example, a structure for clamping the support member 200. In the embodiment shown in FIG. 1A , the mounting device body 110a is composed of a pair of clamping members. In the embodiment shown in FIG. 1A , the pair of clamping members can be tightened toward each other by a fastening member 300 to clamp the support member 200 (particularly the neck portion of the support member 200), thereby fixing the mounting device body 110a to the support member 200. In the embodiment shown in FIG. 1A , the fastening member 300 is a combination of a bolt and a nut, but the present invention is not limited thereto.

[0024] 1A, an example of a mounting fixture body 110a made up of a pair of clamping members has been described as an example of a structure for fixing the mounting fixture body 110a to the support member 200, but the present invention is not limited to this. The structure for fixing the mounting fixture body 110a to the support member 200 may have any structure as long as it can fix the mounting fixture body 110a to the support member 200. For example, the mounting fixture body 110a may have a structure in which the pair of clamping members shown in FIG. 1A are integrally formed.

[0025] Plate 120a may be for interconnecting multiple modules. Plate 120a has one or more protrusions 121 for interconnecting multiple modules. Plate 120a may be conductive. The number of protrusions 121 may be any number equal to or greater than one, as long as the modules can be interconnected. In the embodiment shown in FIG. 1A, plate 120a has four protrusions.

[0026] The mounting fixture 100 further includes an anti-rotation mechanism 105 that prevents the plate 120a from rotating on the mounting fixture body 110a when the plate 120a is positioned on top of the mounting fixture body 110a. The anti-rotation mechanism 105 is described in more detail below with reference to Figures 2A-2D.

[0027] The support member 200 is, for example, the roof of a building (not shown), in which case the mounting structure 10 may also be referred to as a roof structure.

[0028] The mounting structure 10 further comprises a fastening means 400 for fastening one or more modules. The fastening means 400 cooperates with the mounting body 110a and the plate 120a to enable fastening of one or more modules on the plate 120a. A portion of the fastening means 400 is shown in Figure 1A.

[0029] FIG. 1B is a side view showing an example of a mounting structure 10 of the present invention.

[0030] 1B, the fixing means 400 includes at least a bolt 402 and a nut 403. If necessary, a holding device 401 for holding down one or more modules 500 may also be included. In the embodiment shown in FIG. 1B, the bolt 402 is positioned with the bolt head facing downwards in FIG. 1B, and the holding device 401 is placed on the plate 120a from above the module 500, and then tightened with the nut 403 from above, thereby applying force to the one or more modules 500 in a direction from the holding device 401 toward the plate 120a. This makes it possible to fix the one or more modules 500 on the plate 120a.

[0031] When the plate 120a is placed on the top surface of the mounting fixture body 110a, one or more protrusions 121 of the plate 120a puncture the multiple modules 500 and partially break the paint and / or coating of the multiple modules 500, thereby enabling the plate 120a to connect the multiple modules 500 to each other.

[0032] The one or more modules 500 may be, for example, photovoltaic modules, although the invention is not so limited.

[0033] FIG. 2A is a perspective view showing an example of an anti-rotation mechanism 105 of the mounting device 100 shown in FIG. 1A.

[0034] The plate 120a includes a hole 122 through which a portion of the fastening means 400 (e.g., bolt 402) for fastening one or more modules 500 can be inserted. The mounting fixture body 110a also includes a hole 111a through which a portion of the fastening means 400 (e.g., bolt 402) for fastening one or more modules 500 can be inserted. In the embodiment shown in Fig. 2A, the mounting fixture body 110a includes the hole 111a in an upper portion of the mounting fixture body 110a.

[0035] Plate 120a includes one or more tongues 123a configured to extend along at least a portion of the side of hole 111a when plate 120a is positioned on top of mounting body 110a, and hole 111a in mounting body 110a includes one or more notches 112a having shapes corresponding to one or more tongues 123a of plate 120a. In the embodiment shown in Figure 2A, hole 111a in mounting body 110a has a cylindrical shape, and one or more notches 112a are formed in at least a portion of the cylindrical shape of hole 111a. Specifically, hole 111a in mounting body 110a has a cylindrical base shape with approximately rectangular notches provided at two locations on the periphery of the cylindrical hole.

[0036] When the plate 120a is disposed on top of the mounting fixture body 110a, each of the one or more tongues 123a of the plate 120a is positioned within a corresponding one of the one or more notches 112a in the hole 111a of the mounting fixture body 110a or along the side of the corresponding notch. With this configuration, when the plate 120a is disposed on top of the mounting fixture body 110a and attempts to rotate in a plane parallel to the top surface of the mounting fixture body 110a, the one or more tongues 123a of the plate 120a can contact the side of the hole 111a of the mounting fixture body 110a (particularly, the one or more notches 112a in the hole 111a of the mounting fixture body 110a), thereby preventing the plate 120a from rotating. Thus, in the embodiment shown in FIG. 2A, the anti-rotation feature 105 of the mounting device 100 may be a combination of one or more tongues 123a on the plate 120a and one or more notches 112a in the hole 111a of the mounting device body 110a.

[0037] 2A, the plate 120a has two tongues 123a and the hole 111a of the attachment body 110a has two notches 112a, but the present invention is not limited thereto. The number of tongues 123a may be any integer greater than or equal to 1, and the number of notches 112a may also be any integer greater than or equal to 1.

[0038] FIG. 2B is a perspective view showing another example of the anti-rotation mechanism 105 of the mounting device 100.

[0039] Like plate 120a, plate 120b has holes 122 through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. Also, like mounting fixture body 110a, mounting fixture body 110b has holes 111b through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. In the embodiment shown in Fig. 2B, mounting fixture body 110b has holes 111b in an upper portion of mounting fixture body 110b.

[0040] The plate 120b includes one or more tongues 123b configured to extend along at least a portion of the side of the hole 111b when the plate 120b is positioned on top of the mounting body 110b. In the embodiment shown in FIG. 2B , the hole 111b of the mounting body 110b has a rectangular parallelepiped shape. The one or more tongues 123b of the plate 120b are configured to cross at least one side of the rectangular parallelepiped shape of the hole 111b of the mounting body 110b. Note that the at least one side may be, for example, at least one side of four sides extending on the top surface of the mounting body 110b, at least one side of four sides extending in a direction perpendicular to the top surface of the mounting body 110b (hereinafter referred to as the "vertical direction" in this specification), or a combination thereof.

[0041] 2B , the two tongues 123b of the plate 120b have a shape that at least partially follows three of the four sides of the rectangular parallelepiped shape of the hole 111b of the mounting fixture body 110b on the top surface of the mounting fixture body 110b, thereby being configured to cross the four sides of the rectangular parallelepiped shape of the hole 111b of the mounting fixture body 110b from the top surface to the side surface of the hole 111b of the mounting fixture body 110b. Furthermore, the two tongues 123b of the plate 120b are configured to cross two of the four vertical sides of the rectangular parallelepiped shape of the hole 111b of the mounting fixture body 110b on the side surface of the hole 111b of the mounting fixture body 110b, thereby crossing the four sides of the rectangular parallelepiped shape of the hole 111b of the mounting fixture body 110b. However, the present invention is not limited to this. The number of sides of the rectangular parallelepiped shape of the hole 111b that are crossed by one or more tongues 123b of the plate 120b may be one or more.

[0042] When plate 120b is placed on top of mounting fixture body 110b, one or more tongues 123b of plate 120b are positioned along the side of hole 111b in mounting fixture body 110b. With this configuration, when plate 120b is placed on top of mounting fixture body 110b, if plate 120b attempts to rotate in a plane parallel to the top surface of mounting fixture body 110b, one or more tongues 123b of plate 120b can contact the side of hole 111b in mounting fixture body 110b, thereby preventing plate 120b from rotating. Therefore, in the embodiment shown in FIG. 2B , anti-rotation mechanism 105 of mounting fixture 100 can be a combination of one or more tongues 123b of plate 120b and hole 111b in mounting fixture body 110b.

[0043] 2B, the plate 120b includes two tongues 123b, but the present invention is not limited thereto. The number of tongues 123b may be any integer greater than or equal to one.

[0044] FIG. 2C is a perspective view showing another example of the anti-rotation mechanism 105 of the mounting device 100.

[0045] Like plate 120a, plate 120c has holes 122 through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. Also, like mounting fixture body 110a, mounting fixture body 110c has holes 111c through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. In the embodiment shown in Fig. 2C, mounting fixture body 110c has holes 111c in an upper portion of mounting fixture body 110c.

[0046] The plate 120c includes one or more tongues 123c configured to extend along at least a portion of the side of the hole 111c when the plate 120c is positioned on top of the mounting fixture body 110c. In the embodiment shown in FIG. 2C, the hole 111c of the mounting fixture body 110c has the shape of a quadrangular prism with a diamond-shaped base (hereinafter referred to as a "diamond prism"). The one or more tongues 123c of the plate 120c are configured to cross at least one side of the diamond prism shape of the hole 111c of the mounting fixture body 110c. Note that the at least one side may be, for example, at least one side of four sides extending on the top surface of the mounting fixture body 110c, at least one side of four sides extending perpendicular to the top surface of the mounting fixture body 110c, or a combination thereof.

[0047] 2C , the two tongues 123c of the plate 120c have a shape that at least partially follows adjacent two of the four sides of the diamond-shaped columnar shape of the hole 111c of the mounting fixture body 110c on the top surface of the mounting fixture body 110c, thereby being configured to cross the four sides of the diamond-shaped columnar shape of the hole 111c of the mounting fixture body 110c from the top surface to the side surface of the hole 111c of the mounting fixture body 110c. Furthermore, the two tongues 123c of the plate 120c are configured to cross two sides of the diamond-shaped columnar shape of the hole 111c of the mounting fixture body 110c on the side surface of the hole 111c of the mounting fixture body 110c by each crossing one of the four vertical sides of the diamond-shaped columnar shape of the hole 111c of the mounting fixture body 110c. However, the present invention is not limited to this. The number of sides of the diamond-shaped prism shape of the hole 111c traversed by one or more tongues 123c of the plate 120c can be one or more.

[0048] When the plate 120c is placed on top of the mounting fixture body 110c, each of the one or more tongues 123c of the plate 120c is positioned along the side of the hole 111c of the mounting fixture body 110c. With this configuration, when the plate 120c is placed on top of the mounting fixture body 110c and attempts to rotate in a plane parallel to the top surface of the mounting fixture body 110c, the one or more tongues 123c of the plate 120c can contact the side of the hole 111c of the mounting fixture body 110c, thereby preventing the plate 120c from rotating. Therefore, in the embodiment shown in FIG. 2C , the anti-rotation mechanism 105 of the mounting fixture 100 can be a combination of the one or more tongues 123c of the plate 120c and the hole 111c of the mounting fixture body 110c.

[0049] 2C, the plate 120c includes two tongues 123c, but the present invention is not limited thereto. The number of tongues 123c may be any integer greater than or equal to one.

[0050] FIG. 2D is a perspective view showing another example of the anti-rotation mechanism 105 of the attachment device 100.

[0051] Like plate 120a, plate 120d has holes 122 through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. Also, like mounting fixture body 110a, mounting fixture body 110d has holes 111d through which a portion of fastening means 400 (e.g., bolts 402) for fastening one or more modules 500 can be inserted. In the embodiment shown in Fig. 2D, mounting fixture body 110d has holes 111d in an upper portion of mounting fixture body 110d.

[0052] Plate 120d includes one or more tongues 123d configured to extend along at least a portion of the side of hole 111d when plate 120d is positioned on top of mounting fixture body 110d, and hole 111d in mounting fixture body 110d includes one or more notches 112d having shapes corresponding to one or more tongues 123d of plate 120d. In the embodiment shown in Figure 2D, hole 111d in mounting fixture body 110d has a cylindrical shape, and one or more notches 112d are formed in at least a portion of the cylindrical shape of hole 111d. Specifically, hole 111d in mounting fixture body 110d has a cylindrical base shape with approximately rectangular notches provided at four locations around the periphery of the cylindrical hole.

[0053] When the plate 120d is disposed on top of the mounting fixture body 110d, each of the one or more tongues 123d of the plate 120d is positioned within a corresponding one of the one or more notches 112d of the hole 111d of the mounting fixture body 110d or along the side of the corresponding notch. With this configuration, when the plate 120d is disposed on top of the mounting fixture body 110d and attempts to rotate in a plane parallel to the top surface of the mounting fixture body 110d, the one or more tongues 123d of the plate 120d can contact the side of the hole 111d of the mounting fixture body 110d (particularly, the one or more notches 112d of the hole 111d of the mounting fixture body 110d), thereby preventing the plate 120d from rotating. Thus, in the embodiment shown in FIG. 2D, the anti-rotation feature 105 of the mounting device 100 may be a combination of one or more tongues 123d on the plate 120d and one or more notches 112d in the hole 111d of the mounting device body 110d.

[0054] 2D, the plate 120d includes four tongues 123d and the hole 111d of the attachment body 110d includes four notches 112d, but the invention is not limited thereto. The number of tongues 123d may be any integer greater than or equal to 1, and the number of notches 112d may also be any integer greater than or equal to 1.

[0055] In this way, it is possible to prevent the plate from rotating on the mounting body by reusing or modifying the structure originally required for attaching the module to the roof (i.e., the holes in the mounting body and the holes in the plate). This structure eliminates the need for a complex structure on the top surface of the mounting body to prevent the plate from rotating on the mounting body, the need to thin the top surface of the mounting body, and the size of the plate and the top surface of the mounting body that can be used is not limited. The plate of the present invention can be applied to any mounting body having a hole shaped to correspond to one or more tongues extending from the plate. Furthermore, because the plate can be prevented from rotating on the mounting body without cutting or by only slightly cutting the holes in the mounting body, as has been the case in the past, the strength of the mounting body is not reduced. Furthermore, because it is not necessary for the plate to traverse the top surface of the mounting body and wrap around the side of the mounting body to prevent the plate from rotating on the mounting body, the amount of material used for the plate can be relatively reduced.

[0056] As described above, the present invention has been illustrated using the preferred embodiment of the present invention, but the present invention should not be interpreted as being limited to this embodiment. It is understood that the scope of the present invention should be interpreted only by the claims. It is understood that a person skilled in the art can implement an equivalent scope based on the description of the present invention and common technical knowledge from the description of the specific preferred embodiment of the present invention. [Industrial Applicability]

[0057] The present invention is useful for providing a mounting fixture that can fix an earthing member to a mounting fixture body without thinning the top surface of the mounting fixture body and without the earthing member that can be used being limited by the size of the earthing member and the size of the top surface of the mounting fixture body, as well as a roof structure, etc. that is equipped with such a mounting fixture.
