ABSTRACT:
This disclosure deals with an uneven parallel bar system which provides improved safety and greater speed, convenience and reliability in the adjustment of the bar separation distance to the gymnast's needs, said apparatus comprising two performance bars joined at their corresponding ends by rigidly attached struts of adjustable length, a pair of suspending cables which loop over return pulleys or guides attached to an overhead support beam of the building and attach at their ends to the ends of the bars, and a system of tensioning cables which attach to floor anchors and hold the suspended bars system securely in a static position during use. The specific design of the apparatus permits adjustment of the height and width components of the bar separation distance simultaneously at both ends of the bars by means of a manually controlled or computer controlled electrically powered servo system.
