Patent ID: 7836639

Claim:
A structure mounting and supporting device for attaching a structure on a top surface of a roof having a plurality of pieces of a base material, comprising: first and second fixing members fixed to said base material; and a supporting member carried by said first and second fixing members to fix and support said structure, wherein: said first and second fixing members each have a side portion having a fixing portion that is attached to said supporting member, and a bottom surface that contacts said base material, wherein the fixing portions of the first and second fixing members comprises a round fixing hole; said supporting member comprises: a first end having a side portion provided with a plurality of first attachment portions, each said first attachment portion comprising a plurality of attachment holes that are aligned in said longitudinal direction of said supporting member, wherein at least one of the first attachment portions is connected to the fixing portion of the first fixing member, and wherein each said first attachment portion comprises a round hole, a second end having a side portion provided with a second attachment portion that is connected to the fixing portion of the second fixing member, wherein the second attachment portion comprises an elongated hole, and a top side to fix said structure; wherein said plurality of attachment holes of the first attachment portions and said elongated hole are located along a single straight line extending in said longitudinal direction of said supporting member; wherein said elongated hole has an effective length determined by x+2{√{square root over ((L 2 +R 2 ))}−L} where x represents a length of a line segment bounded by centers of two of said attachment holes which are the most distant from each other, L represents an exposure dimension per piece of said base material in a direction of a tilt of said roof, and R represents a distance in a direction perpendicular to a surface of said roof between top surfaces of those two pieces, respectively, of said base material which are adjacent in said direction of said tilt of said roof; and wherein said supporting member is connected to said first and second fixing members that are fixed to the base material such that an angle formed between said top side of said supporting member and said bottom surface of the first and second fixing members is variable.
