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.

We claim: 1. An annular protective rim attachment for CDs and DVDs, for providing airfoil characteristics and rendering the discs tossable and catchable while maintaining maximum safety and controllability, comprising: an annular rim, larger in diameter than a disc to which it can be attached, means on the annular rim for gripping the outer periphery of a disc for attachment thereto, and an outer portion of the annular rim being soft and flexible in order to lessen injury or damage from impact of the assembled disc and protective rim attachment, and the outer portion of the annular rim comprising a downwardly depending skirt extending from an upper, inner annular portion downwardly and outwardly in an outwardly convex curve providing, at least in part, said airfoil characteristics, the annular rim including, generally at a top portion of said skirt, an annular hinge groove in a position to permit the skirt to be deformed inwardly via bending at the hinge upon impact of the rim attachment when combined with a disc. 2. The annular protective rim attachment of claim 1, wherein the means for gripping a disc comprises a pair of spaced apart lips at an inner side of the annular rim and forming a groove or mouth between them, the groove facing inwardly, the annular rim being integrally molded of a soft and flexible material, and the annular hinge groove being positioned just outwardly from the lips. 3. An annular protective rim attachment for CDs and DVDs, for providing airfoil characteristics and rendering the discs tossable and catchable while maintaining maximum safety and controllability, comprising: an annular rim, larger in diameter than a disc to which it can be attached, means on the annular rim for gripping the outer periphery of a disc for attachment thereto, the means for gripping comprising a pair of spaced apart lips including an upper lip and a lower lip forming a groove or mouth between them, the groove facing inwardly so as to receive the outer edge of a disc, and the groove or mouth including an annular locking groove comprising an enlarged area at a deepest portion of said groove or mouth, and comprising an extra thickness in the upper lip immediately adjacent to the enlarged area, and at least an outer portion of the annular rim being soft and flexible in order to lessen injury or damage from impact of the assembled disc and protective rim attachment. 4. An annular protective rim attachment for CDs and DVDs, for providing airfoil characteristics and rendering the discs tossable and catchable while maintaining maximum safety and controllability, comprising: an annular rim, larger in diameter than a disc to which it can be attached, means on the annular rim for gripping the outer periphery of a disc for attachment thereto, the means for gripping comprising a pair of lips, an upper lip and a lower lip, forming a groove or mouth between them, the groove facing inwardly so as to receive the outer edge of a disc, and the lower lip including, in its inner peripheral edge, at least one insertion notch, thereby to help facilitate attachment of a disc between said lips, and at least an outer portion of the annular rim being soft and flexible in order to lessen injury or damage from impact of the assembled disc and protective rim attachment.
