Having Altitude Control Structure Patents (Class 472/11)
  • Patent number: 5433669
    Abstract: A remotely controlled toy flying system in which the pitch of the toy flying device is controlled by the same drive shaft and drive shaft tube that is used to transmit power to the rotor of the toy flying device. A child can easily control the pitch of the toy flying device by rotating a knob. Rotation of the knob displaces the drive shaft, lifts the pitch link member and rotates the pitch shaft and toy flying device. Tilting the toy flying device causes the rotor to have a horizontal component of thrust causing the toy flying device to rotate in a fixed arc around the pivot member in the direction in which the knob is rotated by the child. Speed of the toy flying device rotor is controlled by the fore and aft motion of a lever.

  • Patent number: 5102126
    Abstract: A toy game consists of a map hung beneath a ceiling or a pole, a model aircraft suspended from a map by flexible, plastic string, and a double remote control--one for flight control and another for altitude control. It is operated indoors or outdoors. The aircraft maneuvers including take-off, climb, descent, and landing are controlled by operators. The system consists of tracks in hanger going along the border of the map of the United States of America, an upper motor, a lower motor in fuselage of aircraft, wheels, wired-plastic string, a battery box, bulbs, electric wires and cables. The upper motor is used for propelling to simulate an aircraft flight with all features along border for locating states and cities. The lower motor is used to make altitude changes. The purpose of AIRPLANE FLYING GAME is to help memorizing the location of states and cities. It is an entertainment game but an educational toy as well.
