Abstract
A friction ball joint and a method for using the friction ball joint are provided. A clam shell is formed from at least two segments. The interior of the clam shell segment, where the ball is in contact, is roughened. The clam shell segments may be interlocked to retain a ball. The surface of the ball is roughened. When the friction ball joint is assembled, the rough surfaces of the ball and the clam shell segments are in contact and resist movement.
Claims5
A friction ball joint, comprising:
- a clam shell ball formed from at least two segments, having a mechanical element extending from a clam shell segment, wherein an inside surface of the clam shell segment is roughened;
- and
- a ball having a roughened surface inserted between the clam shell segments.
A method of using a friction ball joint, comprising:
- attaching a first mechanical element extending from a friction ball joint to an object;
- attaching a second mechanical element extending from the friction ball joint to a second object;
- positioning the first object in a selected position relative to the second object by moving at least one mechanical element of the friction ball joint;
- and
- maintaining the first object in a selected position using friction.
