Radio control helicopter toy

Abstract

The present invention provides a radio control helicopter toy including a mast mounted projecting to the upper side of an airframe so as to be rotated by a main motor, a rotor mounted on the upper part of the mast via a rotor head with the blade surface of a rotor blade capable of inclining, a blade inclining mechanism having an arm with one end part side thereof mounted rotatably on the airframe side and the other end part side thereof is mounted to be driven to approach to the above-mentioned rotor head side by an actuator, for inclining the blade surface of the above-mentioned rotor by the magnetic force generated between magnets mounted on the end part of the arm and the above-mentioned rotor head or between a magnet and a ferromagnetic material, and a receiver loaded on the above-mentioned airframe for controlling the operation of the above-mentioned main motor and the actuator.

1 . A radio control helicopter toy comprising: a mast mounted projecting to the upper side of an airframe so as to be rotated by a main motor loaded on the airframe; a rotor mounted on the upper part of the mast via a rotor head with the blade surface of a rotor blade capable of inclining; a blade inclining mechanism having an arm with one end part side thereof mounted rotatably on the airframe side and the other end part side thereof is mounted to be driven to approach to the rotor head side by an actuator loaded on the airframe, for inclining the blade surface of the rotor by the magnetic force generated between magnets mounted on the end part of the arm and the rotor head or between the a magnet and a ferromagnetic material; and a receiver loaded on the airframe for controlling the operation of the main motor and the actuator.  
   
   
       2 . The radio control helicopter toy according to  claim 1 , wherein the mast has an upper mast and a lower mast to be rotated concentrically in the opposite directions by the main motor; the rotor has an upper rotor mounted on the upper part of the upper mast via an upper rotor head with the blade surface of the upper rotor blade capable of inclining and a lower rotor mounted on the upper part of the lower mast via a lower rotor head with the blade surface of the lower rotor blade capable of inclining; and the blade inclining mechanism is provided on the airframe for inclining the blade surface of the lower rotor.  
   
   
       3 . The radio control helicopter toy according to  claim 2 , wherein a stabilizer for controlling the flight attitude of the airframe is mounted on the upper mast so as to interlock with the upper rotor head.  
   
   
       4 . The radio control helicopter toy according to  claim 1  or  2 , wherein the blade inclining mechanism has the arm to be driven by the actuator provided in four points of the front, back, right and left around the mast.  
   
   
       5 . The radio control helicopter toy according to  claim 1 , wherein a tail pipe is mounted on the rear side of the airframe and a tail rotor to be driven by a tail motor is mounted on an end part of the tail pipe.  
   
   
       6 . The radio control helicopter toy according to  claim 1 , wherein the magnet or the ferromagnetic material mounted on the rotor head of the blade inclining mechanism is formed in a ring-like shape surrounding the rotation center of the mast.
