DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present disclosure is directed to a fastening bracket for a seam-type roof for fastening a member to be fixed onto a seam-type roof, the fastening bracket comprising: a main body, a bolt protruding upward through a hole provided in the main body, and a clamp having a hole through which the bolt passes and held by the threaded portion of the bolt, the main body comprising a base on which the member to be fixed can be placed, a first side gripping portion, and a second side gripping portion opposing the first side gripping portion, the base comprising a spacer protruding upward on a first side edge, a second side edge, or both, for positioning the member to be fixed, the first side gripping portion and the second side gripping portion being configured to grip the seam of the seam-type roof by tightening a first nut arranged on the threaded portion of the bolt protruding into the base portion, and the clamp being configured to fasten the member to be fixed, which is positioned and arranged by the spacer, between the base and the fastening bracket by tightening a second nut arranged on the threaded portion of the bolt protruding into the base portion.

[0010] The disclosed fixing bracket for seam-type roofs (hereinafter also referred to as this bracket) has a simple mounting structure and can be manufactured at low cost. It also provides excellent workability by making it easy to position and fix fixed members such as solar panels onto a seam-type roof.

[0011] This metal fitting can be used to fasten solar panels, piping, heat insulation boards, etc. The seam-type roof to which the fastener is fixed is preferably a seam-type metal folded plate roof.

[0012] 1 to 3 show a front view, a side view, and a perspective view of the metal fitting 100. The metal fitting 100 has a main body 10, a bolt 20 that protrudes upward through a hole provided in the main body 10, and a clamp 30 that has a hole through which the bolt 20 passes and is held by a threaded portion 21 of the bolt 20.

[0013] The main body 10 includes a base 40 on which a member to be fixed can be placed, a first-side gripping portion 50, and a second-side gripping portion 60 opposed to the first-side gripping portion 50. Either the first-side gripping portion 50 or the second-side gripping portion 60 is integral with the base 40, and the other can be rotatably connected to the base 40. "Integrated" may mean being integrally molded or being integrally formed by welding or the like. "Rotarily connected" means being rotatably connected in a direction from the first-side gripping portion 50 to the second-side gripping portion 60, in a direction from the second-side gripping portion 60 to the first-side gripping portion 50, or in both directions.

[0014] The base 40 is provided with spacers 43 protruding upward for positioning the member to be fixed on the first side edge 41, the second side edge 42, or both. The spacers 43 can improve the workability by facilitating the positioning and fixing of the member to be fixed on the seam roof. The spacers 43 preferably have a width 431 of 1 to 4 cm, more preferably 2 to 3 cm. The members to be fixed, such as solar panels, piping, and insulation boards, arranged on the seam roof may thermally expand and interfere with adjacent members to be fixed, but by arranging the spacers 43 at a predetermined interval, the interference can be prevented.

[0015] FIG. 5 shows a schematic top view of an example of a fixed member 3 placed on a seam 2 on a seam-type roof 1 by the spacer 43 of this metal fitting. The seam 2 located on the back side of the fixed member 3 is shown by a broken line. FIG. 6 shows an external photograph of an example of an embodiment in which the base of the seam 2 is sandwiched between the first claw piece 51 and the second claw piece 61 of this metal fitting 100 and the fixed member 3, which is a solar panel, is positioned and placed by the spacer 43. The fixed member 3 can be placed so that its longitudinal direction is oriented perpendicular to the seam 2 so as to straddle two or more seams 2 in order to secure the fixed locations. Therefore, the spacer 43 can be placed so that the width direction of the spacer 43 is perpendicular to the longitudinal direction of the fixed member 3 so as to secure the width between the fixed members 3 in the direction perpendicular to the longitudinal direction of the fixed member 3 (parallel to the seam 2), as shown typically in FIGS. 1 to 3 and 5.

[0016] The metal fitting 100 is arranged on at least two seams that span one longitudinal side of the fixed member, and the spacer 43 of each of the at least two metal fittings 100 can position one longitudinal side of the fixed member. Therefore, the fixed member can be positioned by using at least two metal fittings 100 each having a spacer 43 provided at one of the first side edge 41 or the second side edge 42. By providing the spacer 43 at one of the first side edge 41 or the second side edge 42, the fixed member can be positioned more easily and accurately than when the spacer 43 is provided at both the first side edge 41 and the second side edge 42. In addition, since it is necessary to provide the spacer 43 only at either the first side edge 41 or the second side edge 42, the processing cost and material cost are also low.

[0017] The bolt 20 is inserted through a hole provided in the upper stage 63 of the second side gripping portion 60 and through a long narrow hole provided in the base portion 40 of the first side gripping portion 50 in the direction from the first side to the second side.

[0018] The first-side gripping portion 50 and the second-side gripping portion 60 are configured to grip the seam by tightening a first nut 70 disposed on the threaded portion 21 protruding above the base portion 40 of the bolt 20. In the example shown in Fig. 1, by tightening the first nut 70, the base portion 40 integral with the first-side gripping portion 50 and the upper stage portion 63 of the second-side gripping portion 60 are fixed between the head 22 of the bolt 20, and the base portion of the seam can be clamped between the first claw piece 51 and the second claw piece 61.

[0019] The clamp 30 is configured to fix the fixed member positioned and arranged by the spacer 43 between the base portion 40 and the fixed member by tightening the second nut 80 arranged on the threaded portion 21 protruding above the base portion 40 of the bolt 20.

[0020] In the example shown in Figures 1 and 2, the fixed member positioned and arranged by the spacer 43 can be fixed between the pressing portion 32 and the base portion 40 of the clamp 30 by tightening the second nut 80.

[0021] Clamp 30 has a hole through which threaded portion 21 passes, and is rotatable around threaded portion 21. Clamp 30 has a U-shaped central portion 31 and a retaining portion 32. When clamp 30 is fixing a fixed member between itself and base portion 40, it has an omega-shaped cross section when viewed in the direction from first side gripping portion 50 to second side gripping portion 60.

[0022] The clamp 30 has a pressing portion 32 on one or both sides of the central portion 31. FIGS. 1 to 3 are schematic diagrams of the present fitting including the clamp 30 having the pressing portion 32 on both sides of the central portion 31, and FIG. 4 is a schematic diagram of the present fitting including the clamp 30 having the pressing portion 32 on one side of the central portion 31. The present fitting 100 can be used to fix multiple members to be fixed. When the present fitting 100 is arranged on the outer periphery (end) of multiple members to be fixed, the members to be fixed are located on one side of the present fitting 100, so it is sufficient for the clamp 30 to have the pressing portion 32 on one side. When the present fitting 100 is arranged inside (between) multiple members to be fixed, the members to be fixed are located on both sides of the present fitting 100, so it is sufficient for the clamp 30 to have the pressing portion 32 on both sides.

[0023] The width 311 of the central portion 31 of the clamp 30 can be approximately the same as the width 431 of the spacer 43. By making the width 311 approximately the same as the width 431, the fixed member can be fixed more stably. The width 321 of the pressing portion 32 of the clamp 30 is not particularly limited as long as it can fix the fixed member, but can have a width of, for example, 0.5 to 2 cm, 0.6 to 1.6 cm, or 0.7 to 1.3 cm. The longitudinal direction of the clamp 30 is not particularly limited as long as it can fix the fixed member, but can have a length of, for example, 2 to 10 cm, 3 to 8 cm, or 4 to 6 cm.

[0024] The lower surface of the pressing portion 32 of the clamp 30 has an uneven surface as shown in Fig. 2. By having the uneven lower surface of the pressing portion 32, the member to be fixed can be fixed more stably.

[0025] The head 22 of the bolt 20 can be held by a head holding part 64 having a barb 641 provided on the upper part 63 of the second gripping part 60. The barb 641 prevents the bolt 20 from falling from the head holding part 64, improving workability during construction. The barb 641 can also determine the position of the bolt 20 in the height direction. The bolt 20 can be positioned so that it is held by the head holding part 64 by pushing it in.

[0026] Preferably, the first side gripping portion 50 and the second side gripping portion 60 are provided with legs 52, 62 on their respective lower edges. By providing the first side gripping portion 50 and the second side gripping portion 60 with legs 52, 62 on their lower edges, the fitting 100 can be easily positioned approximately horizontally on a grooved roof during installation, improving installation efficiency.

[0027] Preferably, the first gripping portion 50 includes a first claw 51 extending downward from a lower portion of the first side edge 41 of the base portion 40 and having a tip pointing to the second side at the lower edge, the second gripping portion 60 includes a terrace portion including an upper step portion 63 detachable from the base portion 40 and a lower step portion having a protruding piece 65, and a second claw piece 61 extending from the lower edge of the lower step portion and having a tip pointing to the first side at the lower edge and facing the first claw piece 51, and the base portion 40 includes a rotatable receiving portion 44 at a lower portion of the second side edge 42 of the base portion 40 for rotatably receiving the protruding piece 65. The rotatable receiving portion 44 is formed continuously with the base portion 40 and may be integrally formed with the base portion 40 or may be welded to the base portion 40.

[0028] The base portion 40 may be provided with a protruding piece on the lower part of the second side edge 42 of the base portion 40, and the second side grip portion 60 may be provided with a terrace portion including an upper step portion 63 that is detachable from the base portion 40, and a lower step portion having a rotatable receiving portion that rotatably receives the protruding piece. However, an embodiment in which the base portion 40 is provided with the rotatable receiving portion 44 on the lower part of the second side edge 42 of the base portion 40 is preferred in that the joining area between the rotatable receiving portion 44 and the base portion 40 is large and the strength is improved, so that sufficient strength can be obtained even if the main body portion 10 is made of aluminum.

[0029] The protruding piece 65 preferably has a spherical tip portion having an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44 as exemplified in Fig. 1. By having the protruding piece 65 have a spherical tip portion having an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44, the protruding piece 65 is rotatably held by the rotatable receiving portion 44, and the fulcrum of the rotational movement of the second-side grip portion 60 can be made more stable.

[0030] The rotatable receiving portion 44 preferably has an inner circumference of more than half the circumference. By having the rotatable receiving portion 44 have an inner circumference of more than half the circumference, it is possible to prevent the protruding piece 65, which has a spherical tip portion having an outer diameter substantially the same as the inner diameter of the rotatable receiving portion 44, from coming off, and it is possible to further stabilize the fulcrum of the rotational movement of the second-side grip portion 60.

[0031] Preferably, the metal fitting 100 has a metal plate 90 with at least one or more protrusions on the upper and lower surfaces on the base 40. FIG. 7 shows a schematic top view of an example of a metal plate 90 having protrusions 93, 94 and a long and narrow hole 95 for passing the bolt 20. The protrusion 93 is a protrusion on the upper surface and has a convex shape on the front side of the paper. The protrusion 94 is a protrusion on the lower surface and has a convex shape on the back side of the paper. When the frame part of the fixed member fixed by the main body 10 and the metal fitting 100 is made of aluminum, an insulating oxide film is formed on the surface. By using the metal plate 90 with at least one or more protrusions 93, 94 on the upper and lower surfaces, the protrusions 93, 94 can break through the insulating oxide film and the metal plate 90 can function as an earth plate. Even if the frame part of the fixed member fixed by the main body 10 and the metal fitting 100 is coated with an insulator other than an oxide film, the protrusions 93, 94 can break through the coating to ensure electrical continuity.

[0032] The number of protrusions 93, 94 is not particularly limited as long as the metal plate 90 functions as an earth plate, but the metal plate 90 preferably has 1 to 10, more preferably 2 to 8, and even more preferably 3 to 6 protrusions 93, 94 on the upper and lower surfaces, respectively.

[0033] The diameter and height of the protrusions 93, 94 can be a size that can break through the surface insulating oxide film or coating of the fixed member such as a solar panel, and is, for example, 1 to 5 mm or 2 to 4 mm. The protrusions 93, 94 preferably have a sharp tip in the center so as to easily break through the insulating oxide film or coating.

[0034] The protrusions 93, 94 are disposed on the upper and lower surfaces of the metal plate 90, preferably at positions facing the retaining portion 32 of the clamp 30, as illustrated in Fig. 7. By disposing the protrusions 93, 94 at positions facing the retaining portion 32 of the clamp 30, the fixed member can be pressed between the retaining portion 32 of the clamp 30 and the protrusions 93, 94, so that the protrusions 93, 94 can be caused to bite into the fixed member and the surface of the base portion 40.

[0035] The material of the metal plate 90 is not particularly limited as long as it is a material that conducts electricity, but from the viewpoint of weather resistance, it is preferably made of stainless steel.

[0036] Preferably, the metal plate 90 has bent portions 91, 92 that are hooked onto the first side edge 41 and the second side edge 42 of the base portion 40. By hooking the bent portions 91, 92 illustrated in Fig. 1 and Fig. 7 onto the first side edge 41 and the second side edge 42 of the base portion 40, the metal plate 90 can be more easily positioned and placed on the base portion 40.

[0037] The metal plate 90 may have a notch 96 for passing the spacer 43 upward. As illustrated in Fig. 3 and Fig. 4, by inserting the spacer 43 into the notch 96, the metal plate 90 can be more easily positioned and disposed on the base portion 40.

[0038] Preferably, the base 40 has a recess 45 on the first side edge 41, the second side edge 42, or both. A cable tie for arranging cables such as an earth line for wiring and a DC cable can be arranged in the recess 45. The cables can be fixed to the recess 45 with the cable tie so as to be located below the recess 45. The cables can be protected from ultraviolet rays because they are covered by the recess 45. When arranging the metal plate 90, the bottom of the recess 45 is recessed below the surface position of the metal plate 90, so that the metal plate 90 can be arranged without interfering with the cable tie.

[0039] The main body 10 is preferably made of aluminum. Since the main body 10 is made of aluminum, it is lightweight and has excellent corrosion resistance (weather resistance). [Explanation of symbols]
