Flying disc

Abstract

A flying disc generally includes a substantially circular, solid outer rim; a substantially circular, inner rim; an annular space therebetween; and, an airfoil disposed within the annular space. The inner rim is concentrically disposed within the solid outer rim, and the airfoil maintains the integrity of the concentricity between the solid outer rim and the inner rim.

1 . A flying disc, comprising: 
 an outer rim comprising a substantially circular, solid ring;    an inner rim comprising a substantially circular ring, said inner rim is concentrically disposed within said outer rim;    an annular space disposed between said outer rim and said inner rim; and    an airfoil disposed within said annular space.    
   
   
       2 . The flying disc of  claim 1 , wherein said outer rim comprises a material selected from the group consisting of elastomeric materials, thermoset materials, thermoplastic materials, polymeric materials, and combinations comprising at least one of the foregoing materials.  
   
   
       3 . The flying disc of  claim 1 , wherein said inner rim comprises a material selected from the group consisting of elastomeric materials, polymeric materials, and combinations comprising at least one of the foregoing materials.  
   
   
       4 . The flying disc of  claim 1 , wherein said inner rim comprises a flexible material selected from the group consisting of elastic, fabric, nylon, rubber, and combinations comprising at least one of the foregoing materials.  
   
   
       5 . The flying disc of  claim 1 , wherein said airfoil maintains the integrity of the concentricity between said outer rim and said inner rim.  
   
   
       6 . The flying disc of  claim 1 , wherein said airfoil comprises an air-flow permeable material.  
   
   
       7 . The flying disc of  claim 6 , wherein said air-flow permeable material is selected from the group consisting of synthetic materials, elastomeric materials, polymeric materials, and combinations comprising at least one of the foregoing air-flow permeable materials.  
   
   
       8 . The flying disc of  claim 1 , wherein said airfoil further comprises a design.  
   
   
       9 . The flying disc of  claim 1 , further comprising a durable material covering said outer rim.  
   
   
       10 . The flying disc of  claim 9 , wherein said durable material is selected from the group consisting of neoprene, dacron/mylar, cloth, nylon, molded plastic, and combinations comprising one of the foregoing materials.  
   
   
       11 . The flying disc of  claim 9 , wherein said durable material comprises a polyester fabric having a polyvinyl chlorine based non-slip surface applied thereupon.  
   
   
       12 . The flying disc of  claim 9 , wherein said durable material comprises a polyester fabric having a plurality of raised nodules capable of generating a plurality of micro vortices during flight.  
   
   
       13 . A flying disc, comprising: 
 a substantially circular, solid outer rim;    a substantially circular, inner rim, said inner rim is concentrically disposed within said outer rim;    an annular space disposed between said outer rim and said inner rim; and    an airfoil disposed within said annular space.    
   
   
       14 . A flying disc, comprising: 
 a substantially circular, solid outer rim;    a substantially circular, flexible inner rim; and    an airfoil comprising a multidirectionally stretchable, air-flow permeable material disposed therebetween;    wherein said flexible inner rim is concentrically disposed within said solid outer rim, and said airfoil is disposed between said solid outer rim and said flexible inner rim to maintain the integrity of the concentricity between said solid outer rim and said flexible inner rim.
