Radio control flying toy

Abstract

There is disclosed a radio control flying toy in which an airframe can be easily floated and a running direction can be easily controlled. The toy is provided with: an airframe 11 formed into a rectangular plate shape having a flat bottom surface on a lower side; first to fourth propellers 16 a , 16 b , 16 c , and 16 d which are disposed in four corners forming at least a quadrangular shape on the lower side of the airframe 11 and which feed air toward a bottom-surface side to float the airframe 11 ; first to fourth driving means 17 a , 17 b , 17 c , and 17 d which drive the first to fourth propellers 16 a , 16 b , 16 c , and 16 d , respectively; a control unit 20 which individually controls driving outputs of the first to fourth driving means 17 a , 17 b , 17 c , and 17 d , respectively; a transmitter 30 for transmitting a control signal for flight from the outside to the control unit 20 ; and a battery 21 which supplies power to the first to fourth driving means 17 a , 17 b , 17 c , and 17 d and the control unit 20.

1 . A radio control flying toy comprising: 
 an airframe formed into a rectangular plate shape and having a bottom surface which is flat on a lower side;    first to fourth propellers which are disposed in four corners forming at least a quadrangular shape on the lower side of the airframe and which feed air to a bottom-surface side to float the airframe;    first to fourth driving means for driving the first to fourth propellers, respectively;    a control unit which individually controls driving outputs of the first to fourth driving means, respectively;    a transmitter which transmits a control signal for flight from the outside to the control unit; and    a battery which supplies power to the first to fourth driving means and the control unit.    
   
   
       2 . The radio control flying toy according to  claim 1 , wherein the airframe is constituted of an upper main body which contains the control unit and the battery and a lower main body disposed under the upper main body and formed into a rectangular plate shape, attaching holes are made in positions of the four corners forming the quadrangular shape of the lower main body, and the first to fourth propellers are disposed in the attaching holes.  
   
   
       3 . The radio control flying toy according to claim  1 , wherein the first to fourth propellers include a pair of propellers positioned along one diagonal line of the four corners forming the quadrangular shape of the airframe and rotated in one direction, and a pair of propellers positioned along the other diagonal line and rotated in the other direction.  
   
   
       4 . The radio control flying toy according to  claim 1 , wherein the first to fourth propellers include a pair of propellers positioned on the right side of the four corners forming the quadrangular shape of the airframe and rotated in one direction, and a pair of propellers positioned on the left side and rotated in the other direction.  
   
   
       5 . The radio control flying toy according to  claim 1 , wherein the transmitter has an operation lever for generating a control signal to individually raise or lower the driving outputs of the first to fourth driving means.  
   
   
       6 . The radio control flying toy according to  claim 5 , wherein the operation lever has right and left operation levers which rotate the propellers from a perpendicular state toward one side and the other side, and generates the control signal to individually raise or lower the driving output of any of the first to fourth driving means in response to rotating operations of the right and left operation levers to one side and the other side, respectively.  
   
   
       7 . The radio control flying toy according to  claim 1 , wherein the transmitter has an operation button for generating a control signal to individually raise or lower the driving outputs of the first to fourth driving means, respectively.  
   
   
       8 . The radio control flying toy according to  claim 7 , wherein the operation button has four operation buttons corresponding to the first to fourth driving means for front, back, left, and right, respectively.
