Abstract

A joint mechanism having a movement between relative members about a center of rotation located at a point where a first line extends from one of the members intersects a second line extending from the opposite member is disclosed. Multiple joint mechanisms may be aligned together along with common lines being the axis of rotation of each joint mechanism to provide a concentric spherical joint mechanism. Concentric spherical joint mechanism may be used to assemble truss frame structures.
