Image Number 2 for United States Patent #5191160.
A metal waist band held firmly in place by an adjustable nylon strap supports a lockable ball joint to which an adjustable bracket rod is affixed clasping the instrument and holding it away from the deadening effects of one's body. This device provides the following new capabilities: improved instrument stability, improved instrument positionability, improved instrument volume, and improved instrument tone quality. The player benefits from the stand point of health by the fact that the device places the weight of the instrument at the waist, devoiding neuromuscular problems frequently resulting from the shoulder method. Furthermore, the stability and position of the instrument secured by this device affords the player a greater fluency of technique.
