SEAMLESS LAMINATED BASKETBALL

Abstract

A seamless laminated basketball has a carcass and multiple outer covers attached to an outer surface of the carcass. Each outer cover has a thin portion formed around a peripheral edge of the outer cover and seamlessly connected to the thin portions of adjacent outer covers. As widths of the thin portions of the outer covers change, widths of recessed ball channels of the seamless laminated basketball change accordingly. Molds for manufacturing the carcass do not have to be remade or changed. Therefore, the seamless laminated basketball has simplified manufacturing processes and lowered manufacturing cost. Moreover, the outer covers are seamlessly connected to one another, which provides the laminated basketball an intact appearance. Furthermore, the connected outer covers prevent each other from peeling away from the carcass.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a laminated basketball, especially to a seamless laminated basketball.

[0003] 2. Description of the Prior Art(s)

[0004] With reference to FIGS. 10, 11A and 11B, a conventional laminated basketball comprises a carcass 51 having multiple strips 52 formed on an outer surface of the carcass 51, and multiple outer covers 53 disposed between the strips 52 and attached to the outer surface of the carcass 51. The strips 52 are recessed below the outer cover 53 such that multiple ball channels are defined above the strips 52.

[0005] With reference to FIG. 12, another conventional laminated basketball, as disclosed in "An Inflatable Game Ball With Lain-In Channel Or Logo," U.S. Pat. No. 5,931,752, has a carcass 41, multiple outer covers 42 and multiple strips 44. The carcass 41 has multiple grooves 43 formed in an outer surface of the carcass 41. The outer covers 42 are attached to an outer surface of the carcass 41. Gaps between the outer covers 42 correspond to the grooves 43. The strips 44 are securely mounted in the grooves 43, are disposed between the outer covers 42 and are recessed below outer surfaces of the outer covers 42 such that multiple ball channels are defined above the strips 44.

[0006] However, since each mold for manufacturing the carcass 51, 41 has elongated portions with fixed widths for forming the strips 52 or the grooves 43 of the carcass 51, 41, as widths of the ball channels of the conventional laminated basketballs change, the molds for manufacturing the carcasses 51, 41 have to be remade or changed accordingly. Moreover, whenever the widths of the ball channels change, multiple set of the molds have to be prepared for the purpose of mass production on the conventional laminated ball, which causes inconvenient manufacturing processes and increased manufacturing cost. Moreover, since the outer covers 53, 42 are independently attached to the outer surface of the carcass 51, 41, the outer covers 53, 42 have a tendency to peel away from the carcass 51, 41. Furthermore, the grooves 43 cause the conventional laminated basketball to have a non-integrated appearance.

[0007] To overcome the shortcomings, the present invention provides a seamless laminated basketball to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0008] The main objective of the present invention is to provide a seamless laminated basketball. To achieve the foregoing objective, the seamless laminated basketball has a carcass and multiple outer covers. The outer covers are attached to an outer surface of the carcass. Each outer cover has a thin portion formed around a peripheral edge of the outer cover and seamlessly connected to the thin portions of adjacent outer covers.

[0009] The above-mentioned carcass may have multiple grooves formed in an outer surface of the carcass. The above-mentioned thin portion of each outer cover may be mounted in and disposed along corresponding grooves of the carcass.

[0010] The above-mentioned outer surface of the carcass may be smooth.

[0011] The above-mentioned peripheral edges of every two adjacent outer covers may abut each other.

[0012] The above-mentioned thin portions of every two adjacent outer covers may overlap.

[0013] The above-mentioned thin portions of the outer covers may be coated or transfer-printed with colored materials or foils to form ball channels.

[0014] The above-mentioned seamless laminated basketball may further have multiple strips mounted on the thin portions of the outer covers and recessed below outer surfaces of the outer covers to form the ball channels.

[0015] The above-mentioned strips may be rubber strips or composite leather strips.

[0016] As widths of the thin portions of the outer covers change, widths of the recessed ball channels of the seamless laminated basketball change accordingly. Therefore, the widths of the ball channels can be changed at manufacturer's choice. Molds for manufacturing the carcass do not have to be remade or changed. Therefore, the seamless laminated basketball has simplified manufacturing processes and lowered manufacturing cost. Moreover, the outer covers are seamlessly connected to one another, which provides the laminated basketball an intact appearance and the connected outer covers prevent each other from peeling away from the carcass.
