DETAILED DESCRIPTION

The present invention provides a system and a method that overcomes the aforementioned limitations and fills the aforementioned needs by providing a toy flying propeller with a sound-emitting device. The propeller includes a hub with a plurality of blades extending radially from the hub and having an outer edge. An outer ring is connected with the outer edge of the blades and circumferentially surrounds the plurality of propeller blades. At least one sound-emitting device such as a whistle is mounted to the toy flying propeller such that when the toy flying propeller is rotated and launched into the air, the movement of the toy flying propeller through the air causes the sound-emitting device to produce a sound. The toy flying propeller also includes a rotating device such as a launcher that connects with the hub to rotate and launch the toy flying propeller into the air.

All the features disclosed in this specification, (including any accompanying claims, abstract, and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features.

Furthermore, any element in a claim that does not explicitly state “means for” performing a specified function, or “step for” performing a specific function, is not to be interpreted as a “means” or “step” clause as specified in 35 U.S.C. Section 112, Paragraph 6. In particular, the use of “step of” in the claims herein is not intended to invoke the provisions of 35 U.S.C. Section 112, Paragraph 6.

The toy flying propeller has a unique design and shape, along with a carefully-positioned sound-emitting device to create a sound when the toy flying propeller is flying through the air. The toy flying propeller 100, as illustrated in FIG. 1, includes a hub 102 with a central axis 104 about which the toy flying propeller 100 rotates. A plurality of blades 106 radially extend from the hub 102 and form an outer edge 108, which is connected with an outer ring 110 that circumferentially surrounds the blades 106. Attached with a surface of the blades 106 are a plurality of sound-emitting devices, a non-limiting aspect of which is a whistle 112. The whistle 112 is positioned such that the rotation of the toy flying propeller 100 will produce a whistling sound as air moves into the whistle 112. The whistle 112 on each blade 106 is also symmetrically positioned to preserve the aerodynamics and maintain the balance of the toy flying propeller 100 during flight.

The whistle of the present embodiment is further illustrated in FIG. 2. The whistle of the present embodiment is a tubular device with a spherical cap and a plurality of slits which permit air to flow into the whistle to produce a whistling sound. The whistle 202 is attached with the blade 204 such that a first section 206 of the whistle protrudes from a first surface of the blade 208. A second blade 210 illustrates how a second section 212 of the whistle protrudes from an opposing second surface of the blade 210. The first section 206 is tubular and contains a spherical cap 214 with a small slit 216 for air to pass through while the blade 204 is rotating. Air that passes into the slit 216 then passes out of the whistle 202 through a plurality of openings 218 in the second section 212 of the whistle 202. The slit 216 is positioned such that the rotation of the blade 204 will force air directly into the slit 216, creating a loud, consistent whistling sound when the toy flying propeller 200 is in motion. As in the aspect illustrated in FIG. 2, the whistle 202 can be inverted so that the second section 212 of the whistle protrudes from the first surface 208 of the blade while the first section 206 of the whistle protrudes from the second surface of the blade 210.

One skilled in the art will appreciate that the location of the whistles can be varied. For example, the whistle can be formed into the outer ring of the toy flying propeller with an opening on either side of the outer ring. Additionally, a whistle could even be attached with the hub. Furthermore, in yet another aspect, the sound-emitting device can be an electronic device to create any type of sound. The electronic sound-emitting device can be motion-activated so that it only produces the sound while the toy flying propeller is in the air. A motion sensor can be placed in the hub, as can a battery, speaker, and other necessary electronic components.

As illustrated in FIG. 1, the particular angle of the blades is designed so that rotating the toy flying propeller will produce a significant downward force and lift the toy flying propeller into the air. The blades all have the same angled disposition so that rotating the toy flying propeller in only one direction will launch the toy flying propeller into the air, while rotating the toy in the opposite direction will reverse the force generated by the blades and propel the toy flying propeller towards the ground. Additionally, the number of blades can be varied depending on the particular blade shape and width desired.

The toy flying propeller of the present invention also includes a rotating device for rotating and launching the toy flying propeller into the air. In one aspect, the rotating device is a launcher 300 adapted to the hub to rotate and launch the toy flying propeller, as illustrated in FIG. 3A. The launcher includes a rotatable female connector 302 attached with a base 304 that is connected with a handle 306. As illustrated in FIG. 3B, the female connector 302 interlocks with a corresponding male connector 308 on the hub 310, forming an interlocking connection. The launcher 300 further includes a ripcord 314 that, when pulled, is capable of rotating the female connector 302 and male connector 308 in the interlocking connection which thereby rotates the toy flying propeller. Once the rotational velocity of the toy flying propeller reaches a certain point, the vertical force generated by the blades breaks the male connector 308 away from the female connector 302 and launches the toy flying vehicle into the air. One skilled in the art will appreciate that there are numerous mechanisms for rotating and launching an object such as the toy flying propeller.
