  • Patent number: 5284454
    Abstract: A toy helicopter device is disclosed which is capable of a projected nose up ascent and a helicopter nose down descent. The device has a streamlined two dimensional main body comprising a nose, stem, and tail portion. The tail portion is hingedly connected to two helicopter blades arranged adjacent and partially overlapping each other. Resilient means located in the gap between the tail and helicopter blades can be adjusted to control helicopter blade deployment early or late during the catapult projection. At a selected rotational velocity from the catapult, the spinning toy helicopter deploys the helicopter blades to approximately right angles to the main body and the device continues to rotate slowly to the ground. The launch angle relative to the ground is not significant in determining a successful deployment.
