Patent ID: 8550863

Claim:
A gimbal assembly, comprising: first and second generally cylindrical gimbal ends each having a pair of diametrically opposing gimbal yokes including an opposing pair of gimbal yoke pin couplings; a generally cylindrical external gimbal ring having a zigzag shape and having a radial thickness forming an interior opening and including opposing first and second end faces, wherein each of said first and second end faces has a zigzag shape with opposing extensions circumferentially orthogonal to opposing depressions; wherein said first and second gimbal ends are positioned within said interior opening of said gimbal ring such that said first end face of said gimbal ring is convex with respect to said opposing gimbal yokes of said first gimbal end and the second end face of said gimbal ring is concave with respect said opposing gimbal yokes of said first gimbal end when the first end face of said gimbal ring faces towards said first gimbal end and wherein said second end face of said gimbal ring is convex with respect to said opposing gimbal yokes of said second gimbal end and the first end face of said gimbal ring is concave with respect to said opposing gimbal yokes of said second gimbal end when the second end face of said gimbal ring faces towards said second gimbal end, wherein said gimbal yoke pin couplings of said opposing gimbal yokes of said first gimbal end are aligned with said second pair of gimbal ring pin couplings along said second axis and wherein said gimbal yoke pin couplings of said opposing gimbal yokes of said second gimbal end are aligned with said first pair of gimbal ring pin couplings along said first axis; and wherein said first and second gimbal ends are positioned within said interior opening of said gimbal ring such that said first end face of said gimbal ring faces towards said first gimbal end and wherein said second end face of said gimbal ring faces towards said second gimbal end, wherein said gimbal yoke pin couplings of said opposing gimbal yokes of said first gimbal end are aligned with said second pair of gimbal ring pin couplings along said second axis, and wherein said gimbal yoke pin couplings of said opposing gimbal yokes of said second gimbal end are aligned with said first pair of gimbal ring pin couplings along said first axis; and a first pair of gimbal pins which pivotally mount said first pair of gimbal ring pin couplings with said gimbal yoke pin couplings of said opposing gimbal yokes of said second gimbal end along said first axis, and a second pair of gimbal pins which pivotally mount said second pair of gimbal ring pin couplings with said gimbal yoke pin couplings of said opposing gimbal yokes of said first gimbal end along said second axis.
