DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS OF THE DISCLOSURE

(17) The aspects of the disclosed embodiments are directed to a palm or pocket sized disc that is configured to be thrown and fly through the air, also referred to herein as a flying disc. The flying disc of the disclosed embodiments will be approximately two to three inches in diameter and have a height dimension of less than approximately one inch. The size of the flying disc of the disclosed embodiments allows the disc to fit comfortably into a pocket of the person's clothing. The disc includes a perimeter groove that allows the disc to be held like a skipping stone and be thrown in a similar fashion. The flying disc of the disclosed embodiments is configured for flight in excess of 70 yards, and can be caught by the person's bare hand.

(18) FIG. 1 illustrates a disc 100 incorporating aspects of the disclosed embodiments. In this example, the disc 100 has a body that is substantially circular or cylindrical in form, where a diameter of the disc 100 is greater than the height. As illustrated in FIG. 1, the disc 100 is substantially radially symmetric about a central vertical axis 102. As will be described further herein, an outer diameter of the disc 100 is in a range of approximately two to three inches, and a height of the disc 100 generally less than approximately one inch. In alternate embodiments, the outer diameter of the disc 100 can be any suitable diameter, such as 3 to 3.5 inches.

(19) In one embodiment, a weight of the disc 100 is in a range of approximately 0.5 to and including 2 ounces. For example, in the embodiment of FIG. 1, the disc 100 has a diameter of approximately 2.5 inches and a weight of approximately 0.75 ounces. For a disc 100 having a diameter of approximately 3 to 3.5 inches, a weight of such as disc can be approximately 1.5 to and including 2.0 ounces. In alternate embodiments, the disc 100 can comprise any suitable dimensions and weight, as described herein, that will provide the small size and flight characteristics as is described herein.

(20) The volume of material used in the fabrication of the disc 100 relative to the diameter of the disc 100 advantageously provides certain flight characteristics. The weight of the disc 100 relative to its size allows the disc 100 to be thrown farther than might be realized with a scaled down version of a conventional disc, such as a Frisbee, and in some cases, with more accuracy. In one embodiment, an exemplary weight-to-area ratio of the disc 100 is in the range of approximately 4.5 to 5.5 grams per square inch. For example, in the embodiment of FIG. 1, the diameter of the disc 100 is approximately 2.5 inches. For this diameter, the disc 100 has a weight of approximately 0.75 ounces. The weight of the disc 100 of the disclosed embodiments relative to its size, including the diameter and height, enables the disc 100 to fly farther and in some cases with more accuracy, than merely scaled down versions of conventional flying discs.

(21) As an exemplary comparison, the disc 100 illustrated in FIG. 1, is approximately 2.5 times heavier than a standard 10.75 inch Ultimate Frisbee has a weight of approximately 175 grams. The circumference of the disc 100 shown in FIG. 1 creates an area of approximately 4.9 square inches, with a weight of approximately 23.8 grams. This results in a weight to area ratio of approximately 4.86 grams per square inch. A conventional disc, such as the Ultimate Frisbee referred to above, has a weight to area ratio of approximately 1.93 grams per square inch. Merely scaling such a disc down to the size of the disc 100 will not result in the disc 100. The weight of such a disc, scaled down to the diameter of the disc 100, would only be 40% of the weight of the disc 100. Such as disc would not fly as far as the disc 100 when thrown. Some of the heaviest golf discs that are not meant to be caught have a maximum weight to area ratio of approximately 3.5 grams per square inch. The golf discs are generally made of a material that weighs more, or is denser, than the material of the disc 100. The weight of the disc 100 is generally dependent upon the type of material used. It is noted that in one embodiment, the disc 100 is configured to float, particularly when used in water.

(22) The material of the disc 100 generally comprises a soft, flexible material, such as rubber or a rubber-like material. The disc 100 is configured to be lightweight, soft, durable and water proof or water resistant. Examples of a suitable material for the disc 100 can include, but are not limited to a thermoplastic material or rubber (TPR), a thermoplastic elastomer (TPE), a thermoplastic polyurethane (TPU) or other rubber like material. The disc 100 generally comprises a one-piece disc that can be produced using hard-plastic injection moulding.

(23) In the example of FIG. 1, the disc 100 generally comprises a top part or upper surface 110, a bottom part or lower surface 120 and a side part or perimeter portion 130. The top part 110 of the disc 100 includes a center or domed section 112 and is defined by an outer edge or rim member 116, generally referred to as the upper rim or edge 116. The area 114 between the dome section 112 and the outer edge is curved. In the example of FIGS. 1 and 2, the area 114 is inwardly curved, or is generally concave in shape and form, with a curvature as will be described herein. In one embodiment, the area 114 can be referred to as a groove that has a circular form around the upper surface 110.

(24) Referring also to FIGS. 2 and 4, the bottom part or lower surface 120 is defined by an outer edge or rim member, also referred to as the lower edge or rim 118, and a cavity or cupped section 122. In one embodiment, the cupped section 122 includes curved portions 124 on either side of a substantially planar section 126.

(25) As shown in FIGS. 1 and 2, the side part 130 generally comprises or shares the upper rim 116 and lower rim 118. The area 132 between the upper rim 116 and lower rim 118 extends around a perimeter of the disc 100, also referred to herein as perimeter groove 132. The perimeter groove 132 is generally concave in shape and form. As shown in the example of FIG. 2, the perimeter groove 132 curves inwardly.

(26) Referring to FIGS. 2 and 3, in one embodiment, a diameter D1 of the disc 100 is in the range of approximately 2 inches to 3 inches. A preferred diameter D1 is approximately 2.5 inches. A height H1 of the disc 100 is generally less than one inch high. In one embodiment, a preferred height H1 is approximately inches. In the example of FIGS. 1 and 2, a top of the domed section 112 has a height that extends or is slightly higher than the upper rim 116.

(27) In the example shown in FIGS. 2 and 3, the domed section 112 of the top part 110 has a diameter of approximately 1 inch and a curvature 302 of the grooved portion 114 in the top 110 of the disc 100 is approximately inches. The perimeter groove 132 has a curvature 304 in the range of approximately inches to and including inches.

(28) As shown in FIG. 2, in one embodiment, the underside or bottom portion 120 of the disc 100 has a generally cup-shaped form. A height or depth H2 of the bottom portion 120 is approximately 3/16 inches. As shown in FIG. 3, the curvature 306 of the curved portion 124 in the cupped section 122, also referred to as a flare, is approximately inches. An inner diameter of the cupped section 122, or the planar section 126, is in the range of approximately two inches to and including two and one-quarter inches.

(29) As noted above, the disc 100 of the disclosed embodiments has a weight-to-area ratio that is much higher than the conventional flying disc type devices. In one embodiment, the weight-to-diameter ratio can be greater than approximately 4.5 grams per square inch. This allows the disc 100 to be thrown for long distances, despite its smaller size compared to conventional flying discs. Unlike a conventional flying disc device, the weight-to-diameter ratio enables the disc 100 to be thrown with a high angle of attack and a quickly rising flight.

(30) As noted above, the disc 100 of the disclosed embodiments is generally a one-piece rubber disc. Injection moulding is a preferred method of forming the disc 100. In one embodiment, the disc 100 can comprise a two-part assembly. In this example, the disc 100 comprises a soft rim member surrounding a hard central disc member. Another embodiment can include a non-solid disc with air pockets or holes in the disc member. In a further embodiment, the disc member could include a hole in the center to allow the disc to be worn as a bracelet.

(31) FIGS. 5-7 illustrate another example of a disc 400 incorporating aspects of the disclosed embodiments. In this example, the side or outer perimeter 430 of the disc 400 includes rib members 402. The individual rib members 402 extend from the upper rim 416 to the lower rim 418 along the perimeter groove 432. The ribbed members 402 can provide additional gripping action. The finger wrapped around the perimeter needs not to slip, as shown in FIG. 9. The ribbed members 402 provide texturing to assist in the gripping.

(32) FIG. 6 illustrates an example of how the domed section 412 extends above the upper rim 416 by as distance H3. This is also illustrated in the example of FIG. 12, where the disc 500 is shown in an inverted or upside down state.

(33) Referring to FIGS. 8 and 9, one method of using a disc incorporating aspects of the disclosed embodiments is illustrated. The disc 100 illustrated in FIG. 1 is configured to be thrown and caught. Other actions can include throwing the disc at targets, throw the disc for distance and used for yard games. The size, shape and design of the disc 100 allow the disc to be thrown forehand with the index finger wrapped around the perimeter groove 122. This allows the disc 100 to achieve greater distance and accuracy while remaining easily catchable. Yet, the size and weight of the disc 100 allows the disc to be easily carried in one's pocket.

(34) For example, as is shown in FIG. 8, the user places the disc 100 in the throwing hand with the upper surface or domed side 110 facing up. The user places their index finger in the perimeter groove 122 along the side or perimeter groove 130 of the disc 100. The exact placement of the other fingers is less critical. The thumb may be on the top of the disc in the domed region 112, such as shown in FIG. 8, or an edge of the disc. The remaining three fingers can be placed underneath the disc.

(35) FIGS. 10-15 illustrate another example of a disc incorporating aspects of the disclosed embodiments. In the examples of FIGS. 10-15, the ornamental aspects of a design incorporating aspects of the disclosed embodiments are illustrated. FIG. 10 is a perspective view, while FIGS. 11 and 12 are top and bottom views, respectively. FIG. 13 shows the disc positioned upside down, with the domed portion facing down. In the example of FIG. 13, the distance between an upper surface of the disc and the top of the domed section is illustrated. FIG. 14 is a side view, while FIG. 15 is a cross-sectional view of the disc taken along the line A-A. The dimensions illustrated in FIGS. 10-15 are merely exemplary, and provide only one example of a disc incorporating aspects of the disclosed embodiments.

(36) The aspects of the disclosed embodiments provide a disc that is configured to be thrown and caught, also referred to as a flying disc. The flying disc is small in size, generally around 2.5 inches in diameter and having a height of approximately one inch. The weight-to-area is approximately 4.5. The volume of the flying disc of the disclosed embodiments relative to its size advantageously enables the flying disc of the disclosed embodiments to be thrown for long distances. The flying disc of the disclosed embodiments includes a domed section, a perimeter groove section and cupped section in the bottom of the disc to provide improved flight characteristics over more conventional flying discs.

(37) Thus, while there have been shown, described and pointed out, fundamental novel features of the invention as applied to the exemplary embodiments thereof, it will be understood that various omissions and substitutions and changes in the form and details of devices and methods illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention.
