Abstract:
An adjustable mount assembly for an object comprisinga pivot pin including a first contact surface, a mount including a mounting surface for the object, the mount including a first pivot surface mating with the first contact surface for movement of the mount upon the pivot pin, the mount including second, third and fourth pivot surfaces stacked sequentially above the first contact surface, the second and third pivot surfaces facing each other forming a space therebetween, the fourth pivot surface facing away from the third pivot surface, the second, third, and fourth pivot surfaces moving in concert with the mount upon the pivot pin, a first element coupled to the pivot pin in the space between the second and third pivot surfaces, the first element including a second contact surface mating with the second pivot surface and a third contact surface mating with the third pivot surface during movement of the mount upon the pivot pin, a second element coupled to the pivot pin above the fourth pivot surface, the second element including a fourth contact surface mating with the fourth pivot surface during movement of the mount upon the pivot pin, and a locking pin extending through the mount, the first and second elements, and the second, third, and fourth pivot surfaces, and threaded to the pivot pin for rotational movement in a first direction for compressing the first, second, third, and fourth contact surfaces against the first, second, third, and fourth pivot surfaces, respectively, to create multiple concurrent frictional forces at all first, second, third and fourth contact surfaces that limit movement of the mount upon the pivot pin, and in a second direction that relieves the multiple concurrent frictional forces to allow movement of the mount upon the pivot pin.
