Abstract

An annular protective rim attachment designed to grip the outer peripheral edge of compact discs (CD'"'"'s) and digital video discs (DVD'"'"'s), consisting of a flexible, flat top rim (10), the inner periphery of which is molded to form an upper lip (12), lower lip (14), and between these lips, a gripping mouth (16) to securely hold the CD or DVD (28) inside the aperture of said ring. The underside of said ring is shaped in such a way as to create an airfoil (20) adequate to enable the airfoil ring with attached CD or DVD (28) to safely fly and exhibit controllability when tossed into the air. The airfoil ring is made of a soft, flexible non-malleable plastic material which will create a cushioning effect so as not to produce contact impact and resultant injury or damage when tossed into the air.

Claims

1. An annular protective rim attachment for compact discs and digital video discs, commonly referred to as CD'"'"'s and DVD'"'"'s, and herein referred to as discs, for rendering said discs tossable and catchable while maintaining maximum safety and controllability comprising:

2. the rim attachment of claim 1, wherein said rim consists of a means for gripping the outer periphery of said disc,

and,

3. the gripping means of claim 2, wherein said rim consists of a flexible gripping device, consisting of annularly parallel lips, which grip and hold said disc in place within its aperture, and said gripping device being disposed on the inner periphery of said annular rim,

and

4. the gripping device of claim 3, wherein said rim being generally flat on the top side with predetermined width, thickness and cross-sectional shape,

and

5. the rim attachment in claim 1, wherein said rim consists of an underside with predetermined width, thickness and cross-sectional shape so as to create an airfoil that when attached to said disc, creates a means of lift and consequent flight with controllability when tossed into the air by a human,

and,

6. the rim attachment in claim 1, wherein said rim being constructed of a material which is soft in order to lessen injury or damage resultant from contact impact, and said material being flexible in order to allow insertion and removal of said discs from said gripping device,

whereby said disc, which has a rigid, sharp edge, can be tossed and flown by a human with minimal risk of inflicting injury to said human or another human or animal, and with minimal risk of property damage, and

whereby a new use is established for said discs, rendering said discs recyclable.
