ABSTRACT:
A toy glider designed for launching with a slingshot like device, the glider having automatically converging wings for creating a swept-back appearance and for reducing air resistance during launch. The wings automatically rotate forward to an extended or glide configuration after launch. Wings are automatically converged by means of a sliding launching hook, which is pulled forward by the slingshot like launcher. When pulled forward, the launching hook slides forward within a longitudinal central aperture between the inboard portion of the wings, simultaneously rotating the inboard portions of the wings forward. This rotates the outlying wings into a swept-back or converged configuration. A rubber band tends to rotate the wing back into an extended or glide configuration, so when the force applied by the rubber band is greater than the forces opposing it, as when the plane slows, the wings are rotated out into an extended or glide configuration.
