1 Claim, 4 Drawing Figures PATENTEDmszs 197s qm m? AMUSEMENT DEVICE This invention relates to improvements adapted to be sailed through the air and, more particularly. to such a device having whistle structure thereon.
BACKGROUND OF THE INVENTION Conventional amusement devices to be sailed through the air are generally circular and designed with aerodynamic principles in mind so that they can be thrown and caused to sail through the air with a spinning motion. Thus, they remain airborne for certain distances due to a lifting force exerted by the relative movement of air due to the spinning action. Such a device, after being thrown, eventually settles to the ground as the spinning action continues, thus providing amusement and delight to users of the device.
Such conventional devices are essentially noise-free as they sail through the air because of the desire to keep the structure thereof aerodynamically clean. If sound were to be emitted from such a device as it sails through the air and spins, it would add to the enjoyment of the use of the device.
SUMMARY OF THE INVENTION This invention is directed to improvements in devices of the type described, wherein such a device has whistle structure mounted on it to cause a sound to be emitted therefrom as it sails through the air with the sound being generated as a function of the spinning action of the device. To this end, a dome-shaped or dish-shaped device has a circular body whose outer periphery is provided with a number of whistles thereon with the whistles being symmetrically disposed to provide dynamical balance for the body. This will permit it to remain in flight and to spin continuously until it falls to the ground. The spinning action of the device causes quiescent air adjacent to the spinning device to enter the whistles at the relative rotational speed of the device and to cause the sound to be generated with the sound being of sufficient amplitude to be heard by persons throwing the device back and forth to each other.
Each whistle has an air inlet opening, an air passage extending at least partially through it, and a lateral vent communicating with the passage and providing the exit from which the sound is emitted. The device can be formed with a continuous ring defining whistles being in the ring itself. In the alternative, the device can have a number of spaced bosses on the outer periphery of a dome-shaped or dish-shaped with each boss having a whistle therein responsive to the spinning action of the device. The dome or dish shape of the body can be of thin wall construction and the body has an interior depth sufficient to sustain the lift of the device as it sails through the air. The device can be of a one-piece construction and can be formed from a moldable, metallic, or other suitable material.
The primary object of this invention is to provide an amusement device of the type having a circular body adapted to be sailed with a spinning action through the air, wherein the device has a whistle structure on its outer periphery for emitting a sound as a function of the spinning action to thereby add to the users enjoyment of the device.
Another object of this invention is to provide a device of the type described wherein the whistle structure thereof includes a number of spaced whistles mounted on the outer periphery of the device at locations providing aerodynamic balance therefor to permit it to spin continuously as it sails through the air and until it settles to the ground.
Other objects of this invention will become apparent as the following specification progresses, reference being had to the accompanying drawing for an illustration of the invention.
In the drawing:
FIG. 1 is a top plan view of the amusement device of this invention, showing three whistles on the outer periphery thereof;
FIG. 2 is an end elevational view of the device; and
FIGS. 3 and 4 are cross-sectional views taken along lines 3--3 and 44, respectively, of FIG. 1.
The amusement device of this invention is broadly denoted by the numeral 10 and includes a circular member 12 having an outer periphery 14 and adapted to be sailed through the air and, as it does, to spin about a central axis 16 (FIG. 1). Member 12 includes a central, dome-shaped body 18 and a ring 20 secure to body 18 and surrounding the open bottom 22 thereof. The ring is preferably integral with body 18 so that member 12 is of a one-piece construction. It can be formed of plastic, metal or other material permitting it to be sailed through the air in a manner such that the outer surface 23 of body 18, which projects laterally from the plane of ring 20 as shown in FIG. 2, is above the plane of ring 20. Thus, member 12 can experience lift in accordance with known aerodynamic principles so that it will remain in the air for a certain distance after being thrown, such as 50 to feet, depending on the initial velocity imparted to it and its initial height above the ground.
For purposes of illustration, ring 20 has a generally rectangular cross-section, as shown in FIG. 3; however, it can have other cross-sections as well. The ring defines outer periphery 14 of member 12.
Device 10 includes whistle structure on the outer periphery thereof for emitting a sound as the device sails through the air and spins about axis 16. Such whistle structure includes three whistles 24 in ring 20 at symmetrically spaced location about axis 16. The whistles are arranged so that number 12 is dynamically balanced.
Each whistle 24 has a air inlet opening 26 at the upstream end of a short fluid passage 28 which communicates with a relatively long fluid passage 30 having a downstream open end 32. A vent 34 is provided in the outer face of ring 20 and communicates with fluid passage 30. A vane 36 extends partially into the path of the airflow through passage 28, shown in FIG. 1. Thus, air entering inlet opening 26 flows through passage 28 and is divided by vane 36, part of the air going out of vent 34 and part of the air flowing through passage 30. This causes a whistling sound to be emitted with the pitch of the sound being controlled by the effective length of passage 30.
An inclined surface 38 in the outer face of ring 20 cooperates with a curved air scoop 40 adjacent to each air inlet opening 26, respectively, to direct air into the corresponding inlet opening 26 as number 12 spins about axis 16 in the direction of arrow 42 (FIG. 1).
In operation, device 10 is thrown so that the plane of ring 20 remains substantially horizontal and with body 18 being above such plane. The device is given an initial spin in the direction of arrow 42 as it is thrown so that the device will continue to spin about axis 16 as it sails through the air.
During the time in which the device is in the air and is spinning, air will be continuously scooped by air scoops 40 for movement toward respective air inlet openings 26. The air will flow into the inlet openings, through passages 28 and toward passages 30. As the air from each passage 28 enters the upstream end of the corresponding passage 30, the airflow will be split, a portion of which will flow out of the adjacent vent 34 and a portion of which will flow through the corresponding passage 30. This will cause a whistling sound to be emitted by each whistle 24, and such whistling sound will continue so long as body 12 spins about axis 16 in the direction of arrow 42.
While device has been described with respect to the provision of ring 20, it is possible to make the device without a continuous ring. For instance, whistles 24 can be mounted on the outer periphery of body 18 in any suitable manner provided the body is dynamically balanced. To this end, it is possible to mold into the outer periphery of body 18 a number of bosses which are circumferentially spaced apart and have the whistles formed therein.
