    • Toys and methods for safely and reproducibly launching ring airfoils in a flying orientation. The toys generally comprise a member, a ring airfoil support mounted on the member, and a propelling element configured to move the ring airfoil support along the member from a first to a second position. Contact between the ring airfoil and the ring airfoil support causes the ring airfoil to move with the ring airfoil support as the ring airfoil support moves; this contact is overcome as the ring airfoil support decelerates at the second position, causing the ring airfoil to be launched with forward or both forward and spinning motion. The toys further may comprise a housing to protect the toy and user, a return element to place the toy in an engaged, launch-ready configuration, and a trigger to hold the toy in the engaged configuration until launching. As an additional aspect of the invention, components of the device may be chosen so that the characteristics of the ring airfoil at launch are within certain safety limitations.
    • 用于安全和可重复地以飞行方向发射环形翼型的玩具和方法。 玩具通常包括构件,安装在构件上的环形翼型件支撑件和构造成沿着构件将环形翼型件支撑件从第一位置移动到第二位置的推进元件。 环形翼型件和环形翼片支架之间的接触使得环形翼型件随着环形翼型件支撑件移动而与环形翼片支撑件一起移动; 当环形翼型件支撑在第二位置减速时,克服了这种接触,导致环形翼片向前或向前或向前和旋转运动。 玩具还可以包括用于保护玩具和使用者的壳体,用于将玩具置于接合的发射准备配置中的返回元件以及将玩具保持在接合配置中直到发射的触发器。 作为本发明的另一方面,可以选择装置的部件,使得发射时的环形翼型件的特性在某些安全限制之内。
