ABSTRACT:
A rotatably interconnected two-seater swing having an aligner means and, in pairs, a stabilizer means, an attachment means, and a position means as a rider assembly. The swing is combined with a seesaw means for inducing endwise swinging. The aligner means may be monoshaft or multishaft. The stabilizer means may be a spreader means or a hanger means, the former being combined with bifurcated tensional support lines, the latter with a single line attached above the center of gravity of a nearby rider. The support lines may be inwardly inclined, upright, or outwardly inclined. The swing travels endwise and sidewise and is capable of describing an apparent figure-eight pattern when the ends of the swing move transpositionally.
