DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(8) As required, detailed embodiments are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary of various and alternative forms. As used herein, the word exemplary is used expansively to refer to embodiments that serve as illustrations, specimens, models, or patterns. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials, or methods that are known to those having ordinary skill in the art have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art.

(9) FIG. 1 is an isometric view showing the head portion of a ball according to one or more exemplary embodiments of the present invention. As shown FIG. 1, ball is made up of panels 2 that are stitched together via stitches 4. The head portion 6 of ball 40 is rounded in shape and is larger in diameter compared to its tail portion 8.

(10) Ball 40 is designed such that head portion 6 always hits the ground first after being thrown or kicked, and the round shaped of head portion 6 helps to ensure that the bouncing behavior of ball 40 is predictable.

(11) FIG. 2 is an isometric view showing the tail portion of a ball according to one or more exemplary embodiments of the present invention. As shown in FIG. 2, tail portion 8 of ball 40 is more elongated in shape and has a smaller diameter compared to head portion 6. More specifically, ball 40 forms a tapered profile extending from head portion 6 to tail portion 8, resulting in a tear drop-shaped structure. This aerodynamic feature allows for one to more easily grip ball 40 in one's hand, as well as catch it.

(12) Additionally, ball 40 includes inflation valve aperture 10 located centrally on one of the panels 2. The inflation valve aperture 10 is of the conventional types well-known in the art.

(13) FIG. 3 is a front view of a ball according to one or more exemplary embodiments of the present invention. As shown in FIG. 3, ball 40 includes a tunnel 12 located in the center of ball 40. Tunnel 12 reduces the frontal surface of ball 40 but only when ball 40 is thrown such that longitudinal axis 16 is perpendicular to the throwing direction.

(14) FIG. 4 is a side view of a ball according to one or more exemplary embodiments of the present invention. As mentioned earlier, ball 40 has a tear drop shape in which head portion 6 more is rounded and has a larger diameter than the more elongated tail portion 8. This results in tapered profile 18. Tapered profile 18 is based on the NACA airfoil design, executed as a 360 degree revolve in longitudinal axis 16 to achieve an aerodynamic shape.

(15) Additional details regarding a ball according to the invention will now be described with reference to FIG. 5.

(16) FIG. 5 is a detailed view of a ball along the longitudinal axis shown in FIGS. 3 and 4 according to one or more exemplary embodiments of the present invention. As mentioned earlier, ball 40 includes tunnel 12. Tunnel 12 begins at head portion 6 where ball 40 has a more rounded, spherical shape, to achieve a more precise and predictable bouncing pattern.

(17) As shown in FIG. 5, tunnel 12 is a tubular structure and is integrated within the center of ball 40. More specifically, tunnel 12 extends in a longitudinal direction from head portion 6 to tail portion 8 and is of a constant diameter in the longitudinal direction.

(18) In an alternative embodiment, tunnel 12 may vary in diameter. For example, tunnel 12 may have a funnel-like shape such that tunnel 12 would have a larger diameter at head portion 6 compared its diameter at tail portion 8.

(19) Ball 40 also includes reinforced duct 14, which defines tunnel 12 and allows tunnel 12 to maintain its original shape when ball 40 is being pressurized. Additionally, as can be seen in FIG. 3, reinforced duct 14 is attached to panels 2 via stitches 4.

(20) According to one embodiment, reinforced duct 14 may be made of a foam material.

(21) According to another embodiment, the foam material may be made from a foam cylinder having a hardness of about 40-80 shore A.

(22) Reinforced duct 14 also includes front end 22 located at head portion 6 and back end 24 located at tail portion 8. As shown in FIG. 5, panels 2 made of outer skin 26 are attached to reinforced duct 14 at front end 22 and back end 24.

(23) In some embodiments, outer skin 26 may be made of a rubber material. More specifically, outer skin 26 may include a two-layer fabric having a rubber adhesive, which helps to improve the flight of ball 40.

(24) Additionally, an example of a panel assembly of a ball according to one or more exemplary embodiments shown in FIG. 6 illustrates the overall structure of panels 2, having curved ends that attach to front end 22 and back end 24 of duct 14.

(25) As shown in FIGS. 5 and 6, panels 2 also include foam lining 28 which is attached to the inner portion of panels 2. Panels 2 can be stitched together via stitches 4 either through outer skin 26 only or through outer skin 26 and foam lining 28.

(26) Reinforced duct 14 also includes tunnel reinforcement material 30 which is disposed around the outer surface of the middle portion of reinforced duct 14 as shown in FIG. 5, for the purpose maintaining the structural integrity of reinforced duct 14 while ball 40 is being kicked or thrown, and to protect one's hands from injury when catching ball 40. Tunnel reinforcement material 30 is made of a stronger but harder material than duct 14.

(27) According to one embodiment, tunnel reinforcement material 30 may be added to the inside of duct 14.

(28) According to another embodiment, tunnel reinforcement material 30 may be added to a section of duct 14 other than its middle portion.

(29) Ball 40 also includes bladder 32, which extends around the outer surface of reinforced duct 14 and the inner surface of panels 2, resulting in a space between the exterior portion of reinforced duct 14 and the interior portion of panels 2 for inflating ball 40. Thus, the shape of bladder 32 follows the characteristic tear drop shape of ball 40.

(30) Bladder 32 also includes an integrated tunnel 34 in the longitudinal direction from head portion 6 to tail portion 8.

(31) As mentioned earlier, and as shown in FIG. 5, bladder 32 extends around the outer surface of reinforced duct 14. As a result, head portion 6 of ball 40 is formed by panels 2 and bladder 32. This construction contributes to the bouncing behavior of ball 40 being more predictable.

(32) According to one embodiment, bladder 32 may be a separate component assembled into ball 40.

(33) According to another embodiment, bladder 32 may be an integral component of reinforced duct 14.

(34) The ball according to the embodiments of the present invention permits one the ability to accurately predict the bouncing pattern of the ball, while being able to throw and kick the ball to achieve a characteristic spiral motion.

(35) This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods.

(36) The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
