Flying disc

Abstract

A flying disc can be thrown back and forth between players as a flying body, which can be flown a certain flying distance even by an unskilled person, and which slowly descends after speed of horizontal movement reduces so that it can be caught easily by the other person. The flying disc includes a disc main body having an upper wall portion having an opening at a middle thereof and a curved face or an inclined face formed downwardly at an outer periphery of the upper wall portion; a propeller and a driving device for rotating the propeller which are disposed at a central portion of the opening; and a wing-shaped member mounted at an angle different from the propeller so as to receive a descending air current generated by rotation of the propeller and apply a rotative force to the disc main body.

1 . A flying disc comprising:
 a disc main body comprising an upper wall portion having an opening at the middle thereof and a curved face or an inclined face formed downwardly at an outer periphery of the upper wall portion;   a propeller and a driving device for rotating the propeller disposed at a central portion of the opening; and   a wing-shaped member for receiving a descending air current generated by rotation of the propeller and applying a rotative force to the disc main body in a direction reverse to the propeller.   
     
     
         2 . A flying disc comprising:
 a disc main body comprising an upper wall portion having an opening at the middle thereof and a curved face or an inclined face formed downwardly at an outer periphery of the upper wall portion;   a propeller and a driving device for rotating the propeller disposed at a central portion of the opening; and   a wing-shaped member mounted at an angle different from the propeller for receiving a descending air current generated by rotation of the propeller and applying a rotative force to the disc main body.   
     
     
         3 . The flying disc according to  claim 2 :
 wherein the driving device is supported by an arm provided near the center of the opening and the wing-shaped member is provided to the arm.   
     
     
         4 . A flying disc according to  claim 3 : wherein the wing-shaped member is formed by shaping the arm. 
     
     
         5 . A flying disc comprising:
 a disc main body including an upper wall portion having an opening at the middle thereof and a curved face or an inclined face formed downwardly at an outer periphery of the upper wall portion;   a propeller and a driving device for rotating the propeller disposed at a central portion of the opening and supported by an arm provided near the center of the opening; and   a wing-shaped member provided to the arm for receiving a descending air current generated by rotation of the propeller and applying a rotative force to the disc main body and,   wherein a protecting member for covering an outer periphery or an upper portion of the propeller is provided to an upper face of the disc main body.   
     
     
         6 . A flying disc comprising:
 a disc main body comprising an upper wall portion having an opening at the middle thereof and a curved face or an inclined face formed downwardly at an outer periphery of the upper wall portion; and   a propeller and a driving device for rotating the propeller disposed at a central portion of the opening,   wherein a reaction force generated in a direction different from a rotating direction of the propeller is transmitted to the disc main body.   
     
     
         7 . The flying disc according to  claim 1 : further comprising a switch or a sensor for rotating the propeller connected to the driving device. 
     
     
         8 . The flying disc according to  claim 1 : further comprising a switch or a sensor for rotating the propeller connected to the driving device,
 wherein the switch or the sensor detects a start of a flight and automatically rotates the propeller.   
     
     
         9 . The flying disc according to  claim 1 : further comprising a centrifugal switch which is energized as the disc main body rotates and rotates the propeller connected to the driving device,
 wherein the propeller is rotated by the rotation of the disc main body as a result of a flight and the rotation of the propeller is stopped by reduction in a rotating speed of or a stop of the rotation of the disc main body as a result of an end of the flight.
