Abstract
A throwable or otherwise launchable aerial toy, which provides two relatively closely spaced colinearly aligned ring wings, with the forward ring wing being larger than the rear ring wing connected through a central slender member. The spokes connecting the rear ring wing to the central slender member can be configured in a fin shape to provide additional aerodynamic stability. The central slender member can be configured with a U-joint connection assembly to eliminate flight wobble due to manufacturing variations. The central slender member can also contain a rotating joint to permit the forward and rear wings or aerodynamic members to rotate independent of one another, separately or in combination with the U-joint connection in the same central slender member connection between the forward aerodynamic member assembly and the tail aerodynamic member assembly.

8. The aerial toy as in claim 5,
wherein a ratio of a diameter of said tail ring wing to a diameter of said forward ring wing is 0.5 or less. -
9. The aerial toy as in claim 1, wherein a distance between a back end of said forward ring wing and a front edge of said tail ring wing is no greater than approximately 3 times the diameter of the forward ring wing.
-
10. The aerial toy as in claim 1, wherein a distance between a back end of said forward ring wing and a front edge of said tail ring wing is no greater than approximately 2 times the diameter of the forward ring wing.
-
11. The aerial toy as in claim 1, wherein a distance between a back end of said forward ring wing and a front edge of said tail ring wing is no greater than approximately 1.5 times the diameter of the forward ring wing.
-
12. The aerial toy as in claim 1,
wherein central slender body includes a U-joint connection connecting a forward ring wing portion of said body to a tail ring wing portion of said body. -
13. The aerial toy as in claim 12,
wherein an axially rotating joint is positioned at one location in said central slender body, either at a first location in said forward ring portion of said body or a second location in said tail ring wing portion of said body. -
14. The aerial toy as in claim 1, wherein said forward ring wing is configured to be graspable.
-
16. The aerial toy as in claim 14,
wherein said rear aerodynamic member is a series of fins connected to a rear portion of said central slender body member.

-
15. An aerial toy, comprising:
-
a ring wine connecting to a central slender body through thin radial spokes, said central slender body member being disposed at a central axis of said ring wing and having a central axis colinear with said central axis of said ring wing, wherein said central slender body member connects through a U-joint connection to a rear aerodynamic member. - View Dependent Claims (17, 18, 19)
wherein said rear aerodynamic member is a rear ring wing connected to a rear portion of said central slender body member. -
18. The aerial toy as in claim 15,
wherein the maximum range of angular deviation between member connected to said U-joint connection is set by the dimensions of a skin around said U-joint that prevents relative angular deviation beyond a set angle. -
19. The aerial toy as in claim 15,
wherein said ring wing is configured to be graspable.
