  However, the thickness of the edge of the solar cell panel differs depending on the company that produced the solar cell panel, and it was necessary to prepare a plurality of types of fixing brackets corresponding to the thickness of the solar cell panel of each company. Therefore, the installer of the solar cell panel has to prepare a plurality of metal fittings corresponding to each company that produced them. Moreover, in the panel fixing metal fitting described in Patent Document 2, the solar cell panel is simply sandwiched between a pair of upper and lower support pieces through which the bolt penetrates and tightened with a nut. Accordingly, when a force is applied to the solar cell panel from below due to strong winds, the upper support piece is inclined with the bolt as a fulcrum, the panel side is lifted and the opposite side is lowered, and the solar cell panel is detached from the panel fixing bracket. .

  A first object of the present invention is to provide a panel fixing bracket and a panel fixing bracket unit capable of fixing a plurality of thickness panels with one type of panel fixing bracket. A second object of the present invention is to provide a panel fixing bracket and a panel fixing bracket unit having a strong panel holding force that prevents the panel from coming off due to strong winds or the like.

  The panel fixing metal fitting according to the first aspect of the present invention includes a hold metal fitting that holds the panel, a bracket metal piece that holds the hold metal fitting, and a shutter metal piece that is sandwiched between the panel and the bracket metal piece that is held by the hold metal fitting. The holding fixture includes a pressing portion that presses an edge of the panel, a first support portion that supports the pressing portion, and a plate portion on which the first support portion is erected. And an insertion portion extending from the end opposite to the end where the first support portion of the plate portion is erected on the opposite side to the extending direction of the first support portion, The plate portion is formed with a first bolt hole through which a tightening bolt for tightening the hold metal fitting, the shutter metal fitting and the bracket metal fitting passes, and the insertion portion has a width on the tip side narrower than a width on the plate portion side. Formed and said The racket bracket includes a flat shutter bracket mounting portion on which the shutter bracket is mounted, and a second support portion that extends in a direction intersecting the shutter bracket mounting portion and supports the shutter bracket mounting portion. The shutter fitting mounting portion is formed with a second bolt hole through which the tightening bolt passes, and an insertion port which is an opening into which the insertion portion is inserted, and the second support portion has the A support bolt hole through which a support bolt for supporting the bracket metal fitting is formed, the shutter metal fitting is formed in a plate-like portion and the plate-like portion, and a plurality of openings through which the fastening bolt penetrates are formed in a row. A third bolt hole, and a plurality of openings formed in the plate-like portion, and a plurality of openings having different sizes into which the insertion portion is inserted are formed in a row, and a plurality of the third bolt holes Forming direction of the opening and the inserted portion The formation direction of the plurality of openings is the same direction, and the size of the insertion port of the bracket metal fitting is at least as large as the largest opening of the inserted portion. It is characterized by that.

  In the panel fixing bracket, the shutter bracket is mounted on the shutter bracket mounting portion of the bracket bracket. In this state, by changing the position of the shutter fitting, the overlapping position of the bracket fitting insertion port and the inserted portion of the shutter fitting is changed, so that the size of the opening into which the holding fitting insertion portion is inserted is changed. Is regulated by the size of the inserted portion of the shutter fitting. In this state, the depth at which the insertion portion of the hold fitting is inserted into the opening formed by the overlap of the insertion opening of the bracket fitting and the insertion portion of the shutter fitting is regulated. If the opening formed by this overlap is large, the insertion part of the hold metal fitting is inserted deep, and if the opening formed by this overlap is small, the insertion part of the hold metal fitting is inserted shallow. Accordingly, the distance between the plate-like portion of the shutter fitting and the holding portion of the hold fitting is changed depending on the position of the shutter fitting. Therefore, the panel fixing bracket can fix panels having various thicknesses without changing the bracket. In addition, when the tightening bolt is used as a fulcrum and the holding part of the holding bracket is used as a force point, the action point is the hold inserted into the opening formed by the overlap of the bracket fitting insertion port and the shutter fitting insertion portion. It becomes the insertion part of the bracket. Since the insertion portion contacts the periphery of the insertion portion of the shutter fitting, it is possible to prevent the holding fitting from being tilted with the fastening bolt as a fulcrum and the pressing portion to rise and the panel from coming off. Accordingly, it is possible to fix a panel having a plurality of thicknesses with a single type of panel fixing bracket, and to realize a panel fixing bracket having a strong panel holding force that does not come off due to strong winds or the like.

  The hold metal fitting is formed in a shape obtained by bending a plate-shaped metal, and the insertion portion is formed in a stepped portion having a width in a direction intersecting with the insertion direction. The plurality of openings may be formed in such a size that each of the stepped portions having a plurality of widths can be inserted. In this case, the depth at which the insertion portion of the holding metal fitting is inserted into the opening formed by the overlap of the insertion port of the bracket metal fitting and the insertion portion of the shutter fitting is the same as the plurality of widths of the insertion portion. It changes step by step by the number. Accordingly, the distance between the holding part of the holding metal and the plate-like part of the shutter metal also changes stepwise by the same number as the plurality of widths of the insertion part. Therefore, the number of steps of the stepped portion of the insertion portion and the height of each step are formed in advance in accordance with the plurality of thickness panels to be held, and are held corresponding to the plurality of thickness panels. it can.

  The pitch of the plurality of openings of the third bolt hole may be the same as the pitch of the plurality of openings of the inserted portion. In this case, the position of the shutter bracket relative to the bracket bracket is determined by penetrating the tightening bolt into any of the plurality of openings of the third bolt hole formed in the plate-shaped portion of the shutter bracket, and the difference between the bracket brackets is determined. The position of the opening of the inserted portion of the shutter fitting that overlaps the insertion slot is determined. Therefore, depending on which opening of the third bolt hole formed in the plate-like portion of the shutter fitting is passed through the tightening bolt, the holding fitting is determined by the opening of the insertion portion of the shutter fitting that overlaps the insertion port of the bracket fitting. The size of the opening into which the plug can be inserted is determined. Therefore, it is possible to determine the distance between the holding part of the holding metal and the plate part of the shutter metal.

  A protrusion may be formed on a portion of the shutter fitting that contacts the lower surface of the edge of the panel of the plate-like portion. In this case, when the edge of the panel is held between the holding part of the hold metal and the plate-like part of the shutter metal, the protrusions bite into the lower surface of the edge of the panel, so that the panel fixing metal and the panel Electrical continuity with the edge can be ensured.

  A holding portion for holding the lower surface side of the edge portion of the panel may be erected on an end portion of the bracket metal fitting opposite to the side on which the support bolt hole is formed. In this case, since the holding portion enters the back side of the edge portion from the lower surface side of the edge portion of the panel, it is possible to prevent the panel from being detached from the panel fixing bracket.

  The bracket fitting includes a pair of the shutter fitting placement portions extending in a direction intersecting the second support portion with the second support portion interposed therebetween, and the shutter on the opposite side to the second support portion. A holding portion that holds the lower surface side of the edge portion of the panel may be provided upright at the end portion of the metal mounting portion. In this case, a bracket fitting in which the second support portion and the pair of shutter fitting placement portions are integrally formed can be realized.
