Flying Cylinder

Abstract

A flying cylinder has a leading portion and a tail portion, wherein the leading portion is pointed to a degree such that the curf thickness is equal or less than 2 mm. In preferred flying toys, the tail potion has an average thickness of at least the thickness of the leading portion.

1 . A hand-propelled flying toy, comprising: 
 a cylindrical front portion having a plurality of tabs that forwardly extend from the front portion and that are configured to provide a forward edge having a curf thickness of equal or less than 2.5 millimeter;    a cylindrical tail portion having an average thickness of between 1 and 4 millimeter in an area that is between 4 centimeter and 6 centimeter from the forward edge; and    wherein the leading portion and the tail portion have a weight distribution such that the forward edge of the flying toy faces forward during flight.    
   
   
       2 . The flying toy of  claim 1  wherein the front portion has a maximum thickness that is equal or greater than the average thickness of the tail portion.  
   
   
       3 . The flying toy of  claim 2  wherein the front portion has a length of less than 2 cm when measured from the forward edge.  
   
   
       4 . The flying toy of  claim 2  wherein outside and inside surfaces of the forward edge form an angle of less than 35 degrees.  
   
   
       5 . The flying toy of  claim 1  wherein the inside surface of the front portion is straight and parallel to an inside surface of the tail portion.  
   
   
       6 . The flying toy of  claim 1  wherein the front portion has an outer diameter that is equal or less than an outer diameter of the tail portion.  
   
   
       7 . The flying toy of  claim 1  wherein a ring is coupled to at least one of the tabs, and wherein the ring is coupled to the front portion.  
   
   
       8 . The flying toy of  claim 1  wherein at least one of the front portion and the tail portion comprises a dimpled surface.  
   
   
       9 . A hand-propellecd flying cylindrical toy having a cylindrical tail portion, a cylindrical front portion, and a plurality of tabs coupled to the front portion and providing a curt, wherein the toy has a perimeter to curf ratio of between 100 and 200.  
   
   
       10 . The flying toy of  claim 9  wherein the cylindrical tail portion has an average thickness T T , wherein the cylindrical front portion has an average thickness T F , and wherein T F ≧T T .  
   
   
       11 . The flying toy of  claim 9  wherein the front portion has a length of less than 2 cm when measured from a forward edge.  
   
   
       12 . The flying toy of  claim 9  wherein the inside surface of the front portion is straight and parallel to an inside surface of the tail portion.  
   
   
       13 . The flying toy of  claim 9  further comprising a ring coupled to at least one of the tabs.  
   
   
       14 . The flying toy of  claim 9  wherein at least one of the tabs is detachable from the front portion.  
   
   
       15 . The flying toy of  claim 9  wherein the perimeter to curt ratio is between 130 and 170.  
   
   
       16 . The flying toy of  claim 9  wherein at least one of the leading portion and the tail portion comprises a dimpled surface.  
   
   
       17 . The flying toy of  claim 9  wherein the leading portion forms a forward edge such that the toy flies predictably at least 25 meters in a horizontal direction when manually thrown.  
   
   
       18 . The flying toy of  claim 9  wherein at least one of the perimeter to curf ratio is between 100 to 120 and a diameter of the cylindrical tail portion is less than 7 inches.  
   
   
       19 . A hand-propelled flying cylindrical toy having a cylindrical tail portion with an average thickness of between 1 millimeter and 3 millimeters and a curf thickness of equal or less than 2.5 millimeters, wherein a plurality of tabs form a forward edge such that the toy flies predictably at least 25 meters in a horizontal direction when manually thrown.  
   
   
       20 . The flying toy of  claim 19  wherein the average thickness is measured in an area that is between 4 centimeter and 6 centimeter from the forward edge.
