Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a special-shaped fourteen-piece leather-coated basketball. Background Technology

[0002] A basketball's structure includes an inner bladder, winding yarn, midsole, outer skin, and valve. The inner bladder is the core of the basketball, located at the innermost layer. The winding yarn is a protective layer on the surface of the inner bladder, usually made of yarn evenly wound around its surface. The midsole is fitted over the winding yarn, primarily serving to support and fix the basketball's shape. The outer skin is the outermost layer of the basketball, attached to the midsole. The valve is the inflation component. Currently, basketballs have eight outer skin pieces, which are sequentially wrapped around the midsole. However, there is a problem with the eight outer skin pieces not fitting well onto the midsole. Utility Model Content

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] This utility model provides a non-standard fourteen-piece leather basketball, including a core 1, a first outer skin 2, a second outer skin 3, a third outer skin 4, and a fourth outer skin 5. The outer surface of the core 1 is provided with a first bonding area 11, a second bonding area 12, a third bonding area 13, and a fourth bonding area 14. There are two first bonding areas 11, and four bonding areas 12, 13, and 14 are each provided with four of each, alternating in a circumferential direction along the core 1. The two first bonding areas 11 are located at both ends of the core 1. The number of first outer skins 2 is the same as the number of first bonding areas 11. Furthermore, the shape of the first skin 2 is consistent with the shape of the first bonding area 11, and the first skin 2 is attached to the first bonding area 11. The number of second skins 3 is consistent with the number of second bonding areas 12, and the shape of the second skin 3 is consistent with the shape of the second bonding area 12. The second skin 3 is attached to the second bonding area 12. The number of third skins 4 is consistent with the number of third bonding areas 13, and the shape of the third skin 4 is consistent with the shape of the third bonding area 13. The third skin 4 is attached to the third bonding area 13. The number of fourth skins 5 is consistent with the number of fourth bonding areas 14, and the shape of the fourth skin 5 is consistent with the shape of the fourth bonding area 14. The fourth skin 5 is attached to the fourth bonding area 14. This utility model provides a special-shaped 14-piece leather basketball, which uses a total of 14 outer skins. Each outer skin is smaller than the 8 outer skins used in traditional basketballs, so that the outer skins used in this utility model fit the natural curvature of the inner tube better, improving the fit between the outer skin and the inner tube and solving the technical problem of poor fit of the 8 outer skins on the inner tube in the prior art.

[0032] As an optional implementation, the intermediate tire 1 is provided with closed elliptical stems 15, long arc-shaped stems 16, and short arc-shaped stems 17. There are four closed elliptical stems 15 and four long arc-shaped stems 16, and eight short arc-shaped stems 17. The four closed elliptical stems 15 are distributed at intervals along the circumferential direction of the intermediate tire 1. The long arc-shaped stems 16 correspond one-to-one with the closed elliptical stems 15. The long arc-shaped stems 16 are located inside the closed elliptical stems 15 and coincide with the long axis of the closed elliptical stems 15. That is, the two ends of the long arc-shaped stems 16 are connected to the two endpoints of the closed elliptical stems 15. The long arc-shaped stems 16 divide the interior of the closed elliptical stems 15 into a third bonding area 13 and a fourth bonding area 14.

[0033] As an optional implementation, two adjacent closed elliptical stem lines 15 are connected by two short arc-shaped stem lines 17, and there is a relatively long interval between the two short arc-shaped stem lines 17. The long side ends of the two adjacent closed elliptical stem lines 15 and the two short arc-shaped stem lines 17 form a second fitting area 12. The short side ends of the four closed elliptical stem lines 15 and the four short arc-shaped stem lines 17 form a first fitting area 11. The four short arc-shaped stem lines 17 are all located on the same side of the intermediate tire 1.

[0034] As an optional implementation, the third skin 4 and the fourth skin 5 are mirror images of each other, and the second skin 3 is a strip structure. The first skin 2 is octagonal, and includes four arc-shaped sides and four short sides, which are connected alternately in sequence, with the arc-shaped sides recessed into the interior of the first skin 2.

[0035] As an optional implementation, the third skin 4 or the fourth skin 5 is provided with a nozzle mounting hole for mounting a nozzle.

[0036] As an optional implementation, multiple friction protrusions are provided on the outer surfaces of the first skin 2, the second skin 3, the third skin 4, and the fourth skin 5 to increase the friction between the basketball and the palm, thereby improving the control of the basketball.

[0037] As an optional implementation, it also includes an inner liner, a winding yarn, and an air nozzle. The winding yarn is wound around the surface of the inner liner, the middle tire 1 is fitted on the winding yarn, and the air nozzle is installed on the inner liner, the middle tire 1, and the third outer skin 4, or on the inner liner, the middle tire 1, and the fourth outer skin 5.

[0038] Compared to other ball-panel basketballs, this novel 14-panel basketball allows the surface to better conform to the natural curvature of the ball, resulting in greater stability during flight and reducing trajectory deviations caused by uneven surfaces. Furthermore, the 14-panel construction provides a more refined feel, allowing players to more clearly sense the contact between the basketball and their hand when dribbling and shooting, thus improving control.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
