Abstract
Process and apparatus providing the automatic locking of the wings of a wing-operated flying toy, wherein a locking device associated with the operating mechanism is applied, under the effect of elastic pressure, against a notch or slot of the circular disk of the draw crank of the operating mechanism, so that when an elastic band attains its normal power under the effect of torsional moment, the locking device is unable to engage or hold its position in the notch or slot; whereas when the power has almost attained its lowest value at the moment when the elastic band is almost completely untwisted, the locking device is able to engage and maintain itself in the slit causing the wing operating mechanism to lock and prevent movement of the wings.
Claims25
A flying toy capable of movement by wing flapping, comprising:
- a hollow body having an elongated shape;
- a wing activation mechanism positioned at a front part of said hollow body including an elastic band providing motive force;
- flexible wings affixed to said wing activation mechanism;
- a winding system for twisting said elastic band, which winding system is installed on a rear portion of said hollow body;
- a steerable tail wing section installed on said rear portion of said hollow body acting as a rudder;
- means for locking said wing activation mechanism during winding of said elastic band, and during flying of the toy upon expending of motive force in said elastic band.
A flying toy capable of movement by wing flapping, comprising:
- a hollow body having an elongated shape;
- a wing activation mechanism positioned at a front part of said hollow body including an elastic band providing motive force, and a drive crank;
- flexible wings affixed to said activation mechanism and said hollow body;
- a winding system for twisting said elastic band, which winding system is installed on a rear portion of said hollow body;
- a steerable tail wing section installed on said rear portion of said hollow body acting as a rudder;
- means for locking said wing activation mechanism during winding of said elastic band prior to flying of the toy, said means for locking comprising a circular plate having a periphery including a slit on said drive crank, and a stop member subject to an elastic force tending to press an active element of said stop member against said periphery of said circular plate.
A process for automatic immobilization of wings of a flying toy operating by flapping of the wings, the flying toy including a wing activation mechanism positioned at a front part and including an elastic band providing motive force, and a drive crank;
- said process comprising applying a stop member of the wing activation mechanism against a circular plate of the drive crank of the wing activation mechanism, which circular plate includes a slit, the stop member not being engageable with the slit when the activation mechanism is moving at a higher torque, and as the elastic band becomes untwisted the stop member engaging the slit to lock the wing activation mechanism and immobilize movement of the wings.
