ABSTRACT:
An articulated gliding ring is provided in which a plurality of elongated members, which may be curved or straight, are pivotally joined to form a closed ring of circular or polyhedric contour, each of the elongated members having, throughout the major portion of its length an airfoil contour. The articulated structure permits the gliding ring to be projected by back-hand delivery of the open ring, or over-hand delivery of the elongated ring grasped at one folded joint; and has the further advantage of permitting the ring to be folded to compact, pocket size for storage and transport. The most compact folding is made possible by disconnecting one of the pivot joints, and by employing straight rather than curved elongated members.
