Patent abstract
The present application discloses an articulating support arm with improved friction joint designs that are facilitated by the use of a non-annular bushing. In particular, the bushing is designed to interact with another portion of the friction joint to prevent rotational movement of the bushing, thereby minimizing the risk of joint malfunction. A bushing that interacts with a larger percentage of the width of a friction cylinder as compared to prior art devices, thereby improving the performance of the joint, is also disclosed. The improved friction joint according to the present invention may comprise an arm joint and/or tilter joint.
