专利汇可以提供Helicopter with rotor having metal ring for flywheel effect专利检索，专利查询，专利分析的服务。并且A toy helicopter having a rotating bladed wheel with a spindle extending from the center and a launcher detachably receiving the spindle for transmitting rotational movement thereby storing kinetic energy in the wheel. At the end of the transmitted rotational movement, the toy is automatically ejected from the launcher and becomes airborne. A fuselage of desired configuration and with suitable landing gear is rotatably mounted on the spindle to allow the wheel to freely spin relative to the fuselage during both the launching movement and flight.，下面是Helicopter with rotor having metal ring for flywheel effect专利的具体信息内容。

权利要求

1. A toy helicopter comprising: a flywheel having a metal ring, a center hub, and wings coupling said hub to said ring; a spindle extending substantially vertically downwardly from said hub and rigidly joined thereto; a fuselage rotatably mounted on said spindle; launching means detachably coupled to said spindle for imparting a rotational movement to said spindle for storing energy in said flywheel whereby, at the termination of said imparting of rotational movement, said spindle becomes automatically disengaged from said launching means to allow said flywheel together with said fuselage to become airborne; said spindle including a torque pin transversely fixed at the lower end thereof within said fuselage; said launching means including a torque head defining two diametrically-opposed spiraling grooves extending downwardly from the top surface thereof for disengagingly receiving opposite ends of said torque pin in said grooves whereby said torque pin remains in said torque head during said imparting of rotational movement and said torque pin becoming automatically released from said torque head upon cessation of said imparting of movement; an annular shoulder radially extending from the bottom portion of said head, two bores extending downwardly from said shoulder adjacent to said head; a drive shaft; said torque head forming one end of said drive shaft; driving means mounted on said drive shaft for rotating said torque head; said driving means including: a handle rotatably mounted on said drive shaft and terminating in said annular shoulder, a drive spool having a draw string mounted thereon, said spool being fixedly secured to the other end of said drive shaft, and said fuselage being restrained from movement along the longitudinal axis of said spindle and having an opening for admitting said head and two downwardly-extending pins for matingly engaging said bores for restraining the rotation of said fuselage while said rotational movement is being imparted to said ring.
