1. A positionally adjustable mechanism, comprising:

  • a pair of elongated members each having a central axis;

    a base member fixed to a first end of one of the elongated members;

    an article to be supported fixed to a first end of the other elongated member;

    a pair of knuckles, each knuckle having an internally splined central hole;

    a cylindrical pin formed with axially extending splines adapted to be inserted through said internally splined holes of the two knuckles;

    a pair of structures each joining one of the knuckles to a second end of one of the elongated members so that the internally splined central hole of the knuckle extends substantially normal to the central axis of its connected elongated member, each such structure comprising a first cylindrical part having axially extending splines and a second part having a hole with internal spines, thereby allowing control of the rotational position of the first and second parts relative to one another, with the central axis of the cylindrical part and the hole being coaxial with the central axis of the connected elongated member and substantially normal to said cylindrical pin;

    whereby, the orientation of the pair of elongated members relative to one another may be adjusted and fixed.
