This is a Continuation-In-Part Application of and claiming priority to pending U.S. patent application Ser. No. 11/353,404, filed Feb. 14, 2006, which is based on and claims priority to U.S. Provisional Patent No. 60/653,888, filed Feb. 15, 2005 and PCT/US05/05410, filed Feb. 18, 2005.
FIELD OF THE INVENTIONThe present invention relates to a flying toy and, more particularly, to a flying toy having a propeller or multi-blade boomerang.
BACKGROUND OF INVENTIONA traditional hand-held flying toy uses a variety of mechanisms for simple sling action and catapult launching. Such mechanism is motor-driven or ripcord powered with bayonet coupling. After the propeller is launched, the propeller generally falls to the ground after the propelling motion can no longer support the flight. In order to re-launch the propeller, the propeller must be picked up and manually engaged with the launching mechanism.
It is desirable to provide a flying toy having a mechanism for catching the propeller in flight and launching the propeller after it has been caught.
SUMMARY OF THE INVENTIONThe present invention provides a landing platform affixed to a handle of a propeller launcher so as to catch a descending propeller. The landing platform has a funnel-shaped receptacle built in the middle of the platform. The propeller launcher comprises a gearbox with inverted conical pinch rollers, a two-prong coupler fitted to a motor shaft and a power button to engage the propeller for spinning it. The landing platform has a circular trough for holding a bubble solution, for example. The propeller has a plurality of nozzles to be seated in the trough when the propeller is engaged with the landing platform. The nozzles are arranged to pick up the bubble solution so that when the propeller is released from the landing platform, it scatters some of the bubble solution as bubbles along the flying path of the propeller.
The main body of the launcher body comprises two-half plastic shells, which accommodates a DC motor, one or more batteries, a gearbox assembly with a press button, and a landing platform preferably made of resilient material. The stem of the separate propeller is outfitted with a conical sleeve, which is retained by the inverted conical pinch rollers when the pinch rollers are moved inward. As such, the propeller is firmly engaged to the gearbox prior to releasing.
In accordance with the present invention, the gearbox is made up of top and bottom shells, sandwiching a freely rotating cam plate with spur gear built on the underside. A plurality of slots which depict the loci of the pinch rollers are built on both top and bottom shelves, and interact with spiral slots built on a rotary cam plate to govern the radial position of each pinch roller in full synchronization. The cam plate is driven by rack meshes to the spur gear built on a cam plate. The rack is linked to a recoiling spring on one end and a power button on the other end.
In a preferred embodiment of the present invention, a metal shaft extended downwardly from the hub of the propeller is enclosed by a conical sleeve. The sleeve is gripped by pinch rollers when closing and thus the propeller is retained in the handle.
Additionally in accordance with the invention, a swivel tip with flat-surface is affixed to the propeller hub. The swivel tip dissipates impact when the propeller hits the ceiling when it is launched vertically indoors. As a result, the propeller adheres to the ceiling for a period before gravity overcomes its self-sustaining upward thrust. driving mechanism causes the blades to spin when the flying toy is operated in the first mode.
Thus, the first aspect of the present invention is a flying toy comprising:
a handle;
a landing platform disposed on one side of the handle, wherein the landing platform comprises a receptacle for accommodating a propeller assembly, wherein the landing platform comprises a circular trough, and the propeller assembly comprises a plurality of nozzles dimensioned to land in the trough.
