Abstract
A hinge assembly which creates a zero backlash situation. The base member has multiple seats, each having two contact ridges. The contact ridges are formed by an intersection of two planes (ideally substantially ninety degrees). A ball interconnect is engaged by the contact ridges of the seat on one side and a similar arrangement of contact seats on the other side (the hinge member). The diameter of the ball interconnect is larger than the distances between the contact ridges. By sandwiching the ball interconnect between the contact ridges of the base member and the contact ridges of the hinge member, a zero backlash is created in which firm and positive contact is maintained between the elements of the hinge.
