Bolted-ball ball-and-socket pivoting joint assembly

A pivoting joint assembly, comprising:

• a base having two semi-spherical sockets defined in a first face thereof, each of said sockets in said base having a centrally-positioned hole extending through said base to a second face thereof opposing said first face;
• a plate having a length and a width, said plate having two semi-spherical sockets recessed within said plate and two semi-spherical protrusions extending from said plate, each of said protrusions aligned with one of said sockets recessed within said plate, said protrusions and said sockets recessed within said plate being arranged along a line disposed along said length of said plate, said plate having a hole extending through a central portion of each of said sockets recessed within said plate and a corresponding one of said protrusions aligned therewith, each of said protrusions partially fitted in a corresponding one of said sockets in said base wherein a gap is defined between said first face of said base and said plate, and wherein each said hole in said plate is aligned with said centrally-positioned hole of a corresponding one of said sockets in said base;
• and
• two bolts, each of said bolts having a head and a threaded post extending from said head, said head including a semi-spherical portion adjacent said threaded post, said threaded post extending through one said hole in said plate and one said centrally-positioned hole in said base wherein said semi-spherical portion of said head nests within one of said sockets recessed in said plate, said threaded post being coupled to said base wherein said base and said plate pivot in a plane through a maximum angle governed only by a combination of said width of said plate, said gap, and a diameter of each said hole in said plate.
