ABSTRACT:
An improved crossarm for use for holding gymnastic or other equipment, including a support for the invalid, the crossarm includes a series of cables that are suspended downwardly for holding a support for the gymnast or invalid, with the cables extending further upwardly for turning about sheaves associated with the approximate ends of the crossarm, and extending into for winding upon a cable holding device that is effective in retracting any cable in the event that slack occurs; the crossarm also is hingedly mounted, at its upper central portion, to provide for pivot of the crossarm in at least two directions to aid and be of convenience to the user.
