ABSTRACT:
A joint comprising a body member defining an annular groove and a pair of tangential notches intersecting the annular groove at diametrically opposed positions. A socket member is comprised of a preferably semispherically shaped frame having an open side and a pair of diametrically opposed knob or pin member. Each knob or pin member is engagable with one of the tangential notches to snap fit the body member within the semispherically shaped frame and within the annular groove. The body member is secured to a mounting bar and the semispherically shaped frame has an elongated slot and the mounting bar passes through the slot. The arrangement is such that the slot defines one path of rotation of the shaped frame member relative to the body member and the annular groove defines a second path of relative rotation between the body member and the shaped frame. Cooperating friction surfaces are formed on the frame and body members to control resistance to movement and maintain the members in their positions of adjustment.
