Circular flying disk toy

Abstract

A flying toy including a cylindrical rim and a flat circular airfoil located within the rim. The centerline of the airfoil is positioned to bisect the side surface of the rim, resulting in a flying toy of increased stability and throwing ease.

What is claimed is:  
     
         1 . A flying toy comprising: 
 A circular center airfoil having a fixed diameter, an outer edge, a top surface, and a bottom surface, the top surface being continuous, planar and flat, the bottom surface being continuous, planar and flat and spaced from the top surface by a fixed distance parallel to the top surface; and    a cylindrical rim having a diameter equal to the diameter of the circular center airfoil fastened to the circular center airfoil at the outer edge of the circular center airfoil, the cylindrical rim having a vertical height that extends beyond the top surface and bottom surface of the circular center airfoil by equal amounts and having a thickness that is no greater than the fixed distance between the top and bottom surface of the circular center airfoil.    
     
     
         2 . The flying toy of  claim 1  wherein the cylindrical rim has a curved outer side surface.  
     
     
         3 . The flying toy of  claim 1  further comprising: 
 weighting means at the intersection of the circular center airfoil and the cylindrical rim for increasing the weight of the toy at the intersection of the airfoil and the rim.  
 
     
     
         4 . The flying toy of  claim 1  wherein the toy is formed as a single plastic part.  
     
     
         5 . The flying toy of  claim 1  wherein the circular center airfoil is a solid member.  
     
     
         6 . The flying toy of  claim 1  wherein the diameter of the circular center airfoil is within the range of five inches to twelve inches, inclusive.  
     
     
         7 . The flying toy of  claim 1  wherein the vertical height of the cylindrical rim is within the range of one inch to two inches, inclusive.  
     
     
         8 . The flying toy of  claim 1  wherein the ratio of the diameter of the circular center airfoil to vertical height of the outer rim is within the range of 5:1 to 12:2, inclusive.  
     
     
         9 . The flying toy of  claim 1  wherein the fixed distance between the top and bottom surface of the circular center airfoil is no greater than {fraction (3/16)} inches.  
     
     
         10 . The flying toy of  claim 4  wherein the thickness of the cylindrical rim is no greater than {fraction (5/64)} inches.  
     
     
         11 . The flying toy of  claim 1  wherein the thickness of the cylindrical rim is less than the fixed distance between the top and bottom surface of the circular center airfoil.  
     
     
         12 . The flying toy of  claim 1  wherein the thickness of the cylindrical rim is about the same as the fixed distance between the top and bottom surface of the circular center airfoil.
