US Patent 7371028 Post mounting system

A post mounting system for a body mounted camera mounting system includes a grip to go about the post of the system and a vernier clamp. The vernier clamp includes a vernier ring which is slidable axially and fixed angularly to the grip. A vernier nut threadably engages the grip and is rotatable on the vernier ring. A clamp ring is integrally formed with the vernier ring and is castellated to be compressible against the post extending through the device. A split clamp ring cooperates with a cam lever for easy clamping of the clamp ring to the castellated ring. An alignment chuck is also associated with the grip for precise alignment of the post in the post mounting system.
