Flying toy having boomerang flight characteristics and controlled landing abilities
View Patent ↗A flying toy assembly having a secondary body suspended from a boomerang rotor configuration. The rotor configuration includes a plurality of rotor blades that radially extend from a common hub area. The central hub area has a top surface, a bottom surface, and a predetermined thickness between the top surface and the bottom surface. An annular grommet extends through the central hub area. The grommet defines a hole having a length generally equal to the thickness of the central hub area. A secondary body is attached to the grommet. A shaft extends from the secondary body. The shaft extends through the hole in the grommet, thereby joining the secondary body to the rotor configuration. Stops are provided on the shaft. The stops are disposed a predetermined distance apart along the shaft. The predetermined distance is at least twice as long as the length of the hole in the grommet.
1. A flying toy assembly, comprising:
a rotor configuration having a plurality of rotor blades that radially extend from a common hub area in a symmetrical pattern, said hub area having a top surface, a bottom surface and a predetermined thickness between said top surface and said bottom surface;
a hole extending though said hub area;
a secondary body;
a shaft extending from said secondary body, wherein said shaft extends through said hole in said hub area of said rotor configuration, thereby joining said secondary body to said rotor configuration; and
stops disposed a predetermined distance apart along said shaft, said predetermined distance being at least twice as large as said predetermined thickness of said rotor configuration, wherein said rotor configuration is free to rotate about said shaft and reciprocally move along said shaft between said stops.
2. The assembly according to claim 1 , further including a grommet lining said hole.
3. The assembly according to claim 1 , wherein said secondary body is configured as an aircraft fuselage.
4. The assembly according to claim 1 , wherein said rotor configuration is made of foam plastic.
5. The assembly according to claim 1 , wherein said predetermined distance between said stops is greater than two times said thickness of said common hub area.
6. The assembly according to claim 1 , wherein said rotor configuration is both selectively attachable to and detachable from said shaft.
7. The assembly according to claim 1 , further including a landing base coupled to said secondary body for supporting said flying toy assembly in an upright position on a flat surface.
8. A toy helicopter assembly, comprising:
a plurality of rotor blades that radially extend from a common hub area, said hub area having a top surface, a bottom surface and a hole extending through said hub area, wherein said hole extends a predetermined length from said top surface to said bottom surface;
a helicopter body;
a shaft extending from said helicopter body, wherein said shaft extends through said hole in said hub area, thereby interconnecting said helicopter body to said plurality of rotor blades; and
stops disposed a predetermined distance apart along said shaft, said predetermined distance being at least twice as long as said hole, wherein said hub area is free to rotate about said shaft and reciprocally move along said shaft between said stops.
9. The assembly according to claim 8 , further including a grommet, wherein said hole is formed through said grommet.
10. The assembly according to claim 8 , wherein said plurality of rotor blades is unistructurally fabricated from a single piece of foam plastic.
11. The assembly according to claim 8 , wherein said predetermined distance between said stops is greater than two times said length of said hole.
12. The assembly according to claim 8 , wherein said rotor configuration is both selectively attachable to and detachable from said shaft.
13. The assembly according to claim 8 , further including a landing base under said helicopter body for supporting said toy helicopter assembly in an upright position on a flat surface.
14. A flying toy assembly, comprising:
a boomerang having at least three rotor blades;
an annular grommet affixed to said boomerang, wherein said grommet defines a hole of a predetermined length;
a secondary body;
a shaft extending from said secondary body through said hole in said grommet, thereby joining said secondary body to said boomerang; and
stops disposed a predetermined distance apart along said shaft, said predetermined distance being at least twice as large as said predetermined length of said hole, wherein said boomerang is free to rotate about said shaft and reciprocally move along said shaft between said stops.
15. The assembly according to claim 14 , wherein said boomerang is fabricated from a single piece of foam plastic.
16. The assembly according to claim 14 , wherein said predetermined distance between said stops is greater than two times said length of said hole.
17. The assembly according to claim 14 , wherein said boomerang is both selectively attachable to and detachable from said shaft.
18. The assembly according to claim 14 , further including a landing base under said secondary body for supporting said flying toy assembly in an upright position on a flat surface.
