<p>A support structure for assisting an exercising dancer in maintaining her balance has vertical legs which support a horizontal rail. The legs are telescopic and adjustable as to length. Suction cups are pivotally mounted on bracing members which are adjustable lengthwise and circumferentially of the legs. The cups can be clamped to surfaces disposed at an angle to the floor on which the legs rests, or to a surface parallel to the floor, and thus lend support to the rail.</p> |
