Description

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 INVENTION

The present invention relates to a flying toy and, more particularly, to a flying toy having a propeller or multi-blade boomerang.

BACKGROUND OF INVENTION

A 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 INVENTION

The 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.

in a first mode to launch the propeller assembly off the landing platform while the propeller assembly is located in the receptacle, and
in a second mode to receive the propeller assembly into the receptacle while the propeller assembly is in flight with a spinning motion, and wherein the fins are made of a shock absorbent material so that when the flying toy is operated in the second mode, the fins hamper a force associated with the spinning motion while the propeller assembly is received into the receptacle. The propeller assembly has a first end, an opposing second end and a shaft connecting the first end to the second end, the shaft defining a spinning axis of the spinning motion, the first end having a plurality of blades to produce a propeller action in air associated with the spinning motion in order to maintain the propeller assembly in the air. Advantageously, the trough is arranged to hold a dispensable material, and the nozzles comprise a mechanical structure for picking up the dispensable material. The dispensable material can be a solution, such as a bubble solution and the mechanical structure comprises a plurality of thin spines distributed in the nozzles.
The second aspect of the present invention is a flying toy for launching a propeller assembly, the propeller assembly having a first end, an opposing second end and a shaft connecting the first end to the second end, the shaft defining a spinning axis, wherein
the first end comprises a plurality of blades to produce a propeller action in air associated with a spinning motion along the spinning axis for keeping the propeller assembly in the air,

DETAILED DESCRIPTION OF THE INVENTION

Reference is made to FIGS. 1 a to 2 b, which illustrate a flying toy according to a preferred embodiment of the present invention. FIG. 1 a shows a propeller assembly 1 that can be used with a launcher 100, as shown in FIG. 1 b. The launcher 100 comprises a handle 2 made of two half shells 5 and 6 and a battery cover 7 disposed at the bottom of the handle 2. As shown in FIG. 1 b, the launcher 100 further comprises a landing platform 3 disposed on top of the handle 2 and a power button 4 below to the landing platform 3. Preferably the landing platform 3 is made of a resilient material. As shown in FIG. 2 a, the landing platform 3 has a funnel-shaped receptacle 38 in the center of the platform so as to catch and to accommodate a propeller assembly 1. A plurality of fins 34 are distributed over the inner wall of the funnel-shaped receptacle 38 in order to reduce the shock caused by the centrifugal force of a spinning propeller. As shown in FIG. 2 b, the handle 2 has a gearbox assembly 64, a battery chamber 46 and a battery cover 7. The gearbox assembly 64 comprises of a plurality of inverted conical pinch rollers 9 distributed in respective radial positions, a DC motor 8 and a power button 4 extending outwardly. The power button 4 is positioned below the receptacle 38. A two-prong driving coupler 10 is disposed on top of the gearbox assembly 64.
FIGS. 3 a-3 c show the exploded views of the gearbox assembly 64 and some components associated with the gearbox assembly. As shown, the gearbox assembly 64 comprises a rotary cam plate 24, sandwiched between a top cover 11 and a bottom cover 12. The top cover 11 has a plurality of linear slots 32 disposed in a radial arrangement. The bottom cover 12 also has a plurality of matching linear slots 33. These linear slots 32, 33 confine the path of each inverted conical pinch roller 9 when the pinch rollers are moved inward before a propeller is launched. The cam plate 24 has a plurality of spiral slots 31 whereupon is seated a bushing 25 adjoined to the pinch roller 9 by means of a knurled shaft 26. A rack 27 meshes to a rooted spur gear 44 on the bottom section of the cam plate 24. One end of the rack 27 is connected to a power button 4 by a metal linkage 28. A recoiling spring 29 is deployed on the other end of the rack 27. In operation, when the power button 4 is pressed, it drives the cam plate 24 into rotation and forces the pinch roller 9 to move inward along the linear slots 32, 33. A leaf switch 30 is disposed on the moving path of rack 27 such that when the rack 27 travels transversely, the leaf switch 30 is triggered by a stepped shoulder 39 built on one side of the rack 27. The leaf switch 30 is used to activate a DC motor 8. The DC motor 8 comprises a motor shaft 40 fitted through the bottom cover 12, the cam plate 24 and the top cover 11. The end portion of the motor shaft 40 is press-fitted with the two-prong coupler 10.
FIG. 4 shows an exploded view of the propeller assembly according to the present invention. As shown, a multi-blade propeller 15 is fitted with a freely swivel tip 14 in the hub 37. A steel shaft 17 is inserted through a register ring 16 and is permanently fixed to the multi-blade propeller 15 with a nylon washer 13 in between. The register ring 16 is further connected to a conical sleeve 19 by means of a tube 18. The register ring 16, the tube 18 and the conical sleeve 19 come into being one embodiment, yet are free to rotate independently of the multi-blade propeller 15. On the other end of steel shaft 17, a nylon washer 20 and a retaining plug 22 with two flat surfaces 41 are located. Further affixed to the retaining plug 22, are a slave coupler 23 with two studs 42 positioned oppositely and a soft washer 21 in between to reduce any shock that may arise. The slave coupler 23 is allowed to rotate freely within certain angular movements in respect to the retaining plug 22.
Reference is now made to FIG. 5 and FIG. 6, particularly to FIG. 5 which illustrates the propeller assembly 1 being caught with the receptacle 38 by a user. As it is halfway seated in the receptacle 38 of the landing platform 3, the propeller assembly 1 is restrained by the soft fins 34 built around the funnel-shaped receptacle 38 before it comes to engage with a driving coupler 10.
In the process of launching, the power button 4 is pressed inward along the direction 35, causing the pinch rollers 9 to converge in order to grip the conical sleeve 19 of the propeller assembly 1, and to pull the propeller assembly 1 further downward in the direction 36. As such, the slave coupler 23 is engaged with the driving coupler 10. Such arrangement provides buffering between the propeller assembly 1 and the receptacle 38. At the same time, the arrangement minimizes the possibility of a descending propeller to bounce off the receptacle 38 because of the collision between the spinning coupler 23 of the propeller assembly 1 and the driving coupler 10 of the gearbox assembly 64 (see FIG. 2 b). In addition, the register ring 16, properly seated in the opening of the funnel-shaped receptacle 38, helps maintaining an upright, non-swaying rotating axis of the propeller 1 when the propeller assembly 1 is spun upward.
In a different embodiment of the present invention, the landing platform of the launcher has a circular trough to hold a certain dispensable material, such as a powder, small particles or a liquid. As shown in FIGS. 7 a and 7 b, the launcher 200 comprises a handle 102 made of two half shelves 105 and 106, a landing platform 103 disposed on the handle 102 and a power button 104 below the landing platform 103. The landing platform 103 also has a funnel-shaped receptacle 138 in the center of the platform and a plurality of fins 134 distributed over the inner wall of the funnel-shaped receptacle 138. In this different embodiment, the landing platform 103 has a circular trough 170. The trough 170 can be used to hold a powder, small particles or a liquid. In particular, the trough 170 can be used to hold a bubble solution 174.
The landing platform 103 is dimensioned to accommodate a propeller assembly 101. As shown in FIGS. 8 a and 8 b, the propeller assembly 101 has a multi-blade propeller 115 connected to a conical sleeve 119 via a shaft 117. A nozzle support 180 having a plurality of nozzles 182 is mounted between the propeller 115 and the conical sleeve 119. As shown in FIG. 8 a, each of the nozzles 182 has a certain mechanical fine-structure 184 for picking up the dispensable material in the trough 170 when the propeller assembly 101 is fully engaged with the launcher 200, as shown in FIG. 9.
As shown in FIG. 9, when the propeller assembly 101 is fully engaged with the launcher 200, the nozzles 182 are seated in the trough 170 and are in contact with the dispensable material 174 in order to pick up some of the dispensable material 174. As such, when the propeller assembly 101 is released or launched from the launcher, the nozzles 182 are able to carry with them some of the dispensable material 174.
FIGS. 10 a and 10 b show the propeller assembly 101 being released from the launcher 200 as the power button 104 is pressed inward along the direction 135. As the propeller assembly 101 is spun upward from the landing platform 103, the dispensable material 174 carried out by the nozzles 182 is scattered along the flying path of the propeller assembly 101. The dispensable material 174 can be a bubble solution, so that when the propeller assembly 101 is spun upward, some of the bubble solution is scattered along the flying path in the form of bubbles 190. In order to efficiently pick up the bubble solution in the trough 170, the fine structure 184 in the nozzles 182 comprises a plurality of thin spines distributed in a circular array inside the nozzles 182, for example.
In sum, according to the present invention, the flying toy has a handle and a driving mechanism to spin a propeller assembly, the propeller assembly having blades on the top end and a freely rotatable conical sleeve on the bottom end. In one embodiment of the present invention, a landing platform is provided on the top of the handle, the landing platform comprises a receptacle to accommodate the propeller assembly. The flying toy is operable in a first mode to launch the propeller assembly off the landing platform while the propeller assembly is located in the receptacle, and in a second mode to receive the propeller assembly into the receptacle while the propeller assembly is in flight with a spinning motion, and wherein the fins are made of a shock absorbent material so that when the flying toy is operated in the second mode, the fins hamper a force associated with the spinning motion while the propeller assembly is received into the receptacle.
The landing platform has a trough to hold some dispensable material. The propeller assembly may comprise a plurality of nozzles or the like to pick up the dispensable material when the nozzles are seated in the trough. The nozzles would scatter the dispensable material along the flying path of the propeller assembly as the propeller assembly is spun upward from the launcher. Preferably, the dispensable material is a bubble solution so that when the propeller assembly is spun upward, the propeller assembly leaves a trail of bubbles along its flying path.
Thus, although the invention has been described with respect to one or more embodiments thereof, it will be understood by those skilled in the art that the foregoing and various other changes, omissions and deviations in the form and detail thereof may be made without departing from the scope of this invention.
