Abstract

[Problem] To be able to reliably fix a solar battery module in an appropriate position on a roof, to have light weight and few components, and to be able to reliably prevent slipping and perform grounding during temporary placement when the fixing position of the solar battery module is adjusted. [Solution] The present invention comprises: a base metal fitting fixed to a rooftop surface; a height-adjusting metal fitting capable of sliding in a vertical direction relative to the base metal fitting; a position-adjusting metal fitting capable of sliding in a horizontal direction relative to the height-adjusting metal fitting; and a fixing metal fitting for sandwiching and fixing the solar battery module between the fixing metal fitting and the position-adjusting metal fitting from the top and bottom, the fixing metal fitting being attached relative to the position-adjusting metal fitting. The position-adjusting metal fitting has: a mounting board part for mounting the solar battery module; a stopper capable of making contact with the edge of a frame provided to the periphery of the solar battery module when the solar battery module is mounted on the mounting board part; and a protrusion for making contact with a conductor part of the frame when the solar battery module is fixed to ensure electrical conductance.

Claims

1. A solar battery module fixture for fixing a solar battery module on a slate roof, comprising:

a plurality of base metal fittings to be fixed on a top surface of said roof,

a height-adjusting metal fitting attached to said base metal fittings so that it can slide longitudinally,

a position-adjusting metal fitting attached to said height-adjusting metal fitting so that it can slide laterally, and

a fixing metal fitting attached to said position-adjusting metal fitting for fixing the solar battery module by vertically holding the solar battery module with said position-adjusting metal fitting,

said position-adjusting metal fitting comprising;

a mounting board part for placing the solar battery module,

a stopper which can come into contact with edges of a frame provided around said solar battery module when it is placed on said mounting board part, and

a protrusion for ensuring electric connection with said frame by coming into contact with a conducting part of said frame while said solar battery module is fixed.

2. The solar battery module fixture according to claim 1,

said base metal fittings consisting of a plate-like fixed part fixedly-contacting with said top surface of said roof and a plate-like extending part arranged perpendicular to said top surface of said roof,

said height-adjusting metal fitting consisting of a first plate-like part arranged perpendicular to said top surface of said roof and a second plate-like part arranged in parallel to said top surface of said roof,

said first plate-like part having a first long hole which is longer in a direction perpendicular to said top surface of said roof,

said second plate-like part having a second long hole which is longer in a direction in parallel to said top surface of said roof,

said height-adjusting metal fitting being attached to said base metal fittings by fixing said plate-like extending part and said first plate-like part with a bolt inserted into said first long hole, so that said height-adjusting metal fitting can slide longitudinally,

said position-adjusting metal fitting being attached to said height-adjusting metal fitting by fixing said mounting board part and said second plate-like part with a bolt inserted into said second long hole, so that said position-adjusting metal fitting can slide laterally.

3. The solar battery module fixture according to claim 2,

said first plate-like part of said height-adjusting metal fitting having a left-and-right pair of lancing parts which project in an extending direction of said second plate-like part and extends in parallel to said first long hole,

a plate-like extending part of said base metal fitting being held between said left-and-right pair of lancing parts.

4. The solar battery module fixture according to any of claim 1,

said fixing metal fitting consisting of a first fixing metal fitting arranged at the end of a plurality of solar battery modules arranged on the roof and a second fixing metal fitting arranged among said plurality of solar battery modules,

said first fixing metal fitting being formed by folding a flat plate in a staircase pattern so that said flat plate can have two lateral parts and two longitudinal parts,

said two longitudinal parts being two-tiered in parallel to each other, an upper longitudinal part of said two-tiered longitudinal parts comes into contact with outer edge of said frame of said solar battery module and a lower longitudinal part positions an eave cover for covering end surface on eaves edge side of said solar battery modules.

5. The solar battery module fixture according to claim 1,

said position-adjusting metal fitting consisting of a first position-adjusting metal fitting arranged at the eaves edge side of a roof, and a second position-adjusting metal fitting arranged at the other side of the roof,

said first position-adjusting metal fitting comprising an eaves cover fixed part for fixing the eaves cover which covers the eaves edge side of the solar battery module,

said second position-adjusting metal fitting comprising said two stoppers arranged with some space therebetween, and

said stoppers coming into contact with an inner edge of said frame.

6. The solar battery module fixture according to claim 2,

said plate-like fixed part of said base metal fittings consisting of a first fixed part extending in one direction, and a second fixed part extending in a direction opposite to the direction in which the first fixed part extends,

said second fixed part being formed by making a cut in a part of said plate-like extending part and folding the cut part, and

a protrusion formed by upwardly transforming a board forming said plate-like fixed part being provided so that the protrusion strides over said first fixed part and said second fixed part.

7. The solar battery module fixture according to claim 1,

said position-adjusting metal fitting consisting of a common position-adjusting metal fitting with a common structure arranged at the eaves edge side and at the other side of a roof,

said common position-adjusting metal fitting comprising said stopper and said protrusion,

said stopper consisting of one stopper which can come into contact with outer edge of said frame, and

said protrusion being formed by upwardly folding corners of said mounting board part.

8. The solar battery module fixture according to claim 4,

said first fixing metal fitting and said second fixing metal fitting being separately fixed to said height-adjusting metal fitting and said position-adjusting metal fitting by a bolt and a nut,
