Abstract
A flying toy controllable in three dimensions. A gas inflatable envelope preferably a helium filled balloon is secured to a remote controlled first motor with a normally vertical output shaft having a first propeller. The output shaft is tiltable such that it assumes a plurality of angular positions in a vertical plane. A second remote controlled motor with output shaft and associated propeller is also secured to the balloon and when activated rotates the toy about its vertical axis. The two motors and the mechanism for tilting the output shaft of the first motor provide a flying toy controllable in three dimensions. Substantially, all of the buoyancy of the balloon is provided by the lighter-than-air gas of the balloon.
Claims9
A flying toy controllable in three-dimensions comprising:
- (a) an airborne component comprising an inflatable envelope containing a gas, said envelope having a vertical axis;
- (b) a first motor secured to said envelope by a gondola suspended beneath said envelope, said first motor having a first output shaft capable of assuming a plurality of selected positions in a vertical plane and with a first propeller mounted thereon for rotation therewith, said first output shaft, when vertical, being coaxial with said vertical axis;
- (c) first output shaft tilting means for selectively causing said first output shaft to achieve at least two positions in said vertical plane intersecting said vertical axis;
- (d) a second motor secured to said envelope, said second motor having a second output shaft with a second propeller mounted thereon for rotation therewith, said second output shaft being tangential to an imaginery horizontal circle having a center in the line of said first output shaft, when vertical;
- (e) said second motor when energized rotates said second propeller to thereby cause said envelope to rotate about said vertical axis;
- (f) power supply means for energizing said first and said second motors and for activating said first output shaft tilting means;
- and,
- (g) control means for said power supply means.
A flying toy controllable in three-dimensions comprising:
- (a) a helium filled balloon;
- (b) a gondola suspended from said balloon and having a vertical central axis;
- (c) a first motor, having a first output shaft housed in said gondola, said first output shaft being normally vertical and coaxial with said vertical central axis yet capable of selectively achieving a plurality of angular positions in a vertical plane;
- (d) a first propeller secured to said first output shaft;
- (e) a second motor, having a second output shaft housed in said gondola, said second output shaft, lying in a horizontal plane and tangential to a horizontal imaginery circle having a center passed through by said vertical central axis;
- (f) a second propeller secured to said second output shaft;
- (g) a tilting means for selectively tilting said first output shaft in said vertical plane;
- (h) an electrical power supply connected to said first and said second motors;
- and,
- (i) control means for selectively supplying said electrical power supply to said first and second motor.
