    • An annular protective ring attachment designed to grip the outer peripheral edge of all compact discs (CDs) and digital video discs (DVDs) which, when used in combination with said CD or DVD, creates an airfoil. The airfoil ring consists of an inner periphery, which is molded to form a top lip (3) and bottom lip (4), and between these lips, a gripping mouth (6), which securely holds the CD or DVD (7,76) inside the aperture of the airfoil ring. The body of the airfoil ring is curved in such a way as to create an airfoil adequate to enable the airfoil ring with inserted CD or DVD to be safely tossed into the air and to exhibit controllability in flight. The airfoil ring is constructed of a soft, flexible plastic material, and uses a hinge groove (5) on the top side of the airfoil skirt (1) and a hinge groove reaction area (9) on the underside of the airfoil skirt (1) to dissipate the contact force upon impact and create a cushioning effect so as to avoid resultant injury or damage when tossed into the air. A locking groove (8) inside the gripping mouth area (6) traps the sharp edge of the CD or DVD (7), preventing it from dislodging upon impact and causing injury.
    • 设计用于夹持所有光盘(CD)和数字视频光盘(DVD)的外围边缘的环形保护环附件,当与所述CD或DVD结合使用时,产生一个翼型件。 翼型环由内周构成,其内模被形成以形成上唇(3)和底唇(4),并且在这些唇之间,夹紧口(6)牢固地保持CD或DVD(7,76 )在翼型环的孔内。 机翼环的主体以这样的方式弯曲,以便产生足以使具有插入的CD或DVD的翼型环能够安全地扔进空气中并且在飞行中展现可控性的翼型件。 翼型环由柔软的柔性塑料材料构成,并且使用翼型裙部(1)的顶侧上的铰链槽(5)和翼型裙部(1)的下侧上的铰链槽反作用区域(9) )在冲击时消除接触力,并产生缓冲作用,以避免在扔入空气时造成伤害或损坏。 夹持口区域(6)内的锁定槽(8)捕获CD或DVD(7)的锋利边缘,防止其在撞击时被移除并造成伤害。
