Abstract

A ball structure used in a baseball or a softball comprises a ball core; two covers enclosing the ball core; the two covers being seamed together by a seaming wire; an edge of each cover being formed with a plurality of wire holes for being passed by a seaming wire; a plurality of recesses arranged near an edge of each cover; each recess being formed between a respective one of the wire holes and the edge of each cover; a direction of each recess being identical to the seaming direction of the seaming wire; thereby when the two covers enclose the ball core by using the seaming wire; the part of the seaming wire exposing out of the covers fall into the recesses.

Description

FIELD OF THE INVENTION

The present invention relates ball structures, and in particular to a ball structure used in a baseball or a softball, wherein a plurality of recesses arranged near an edge of each cover; and part of the seaming wire exposing out of the covers will fall into the recesses. Thereby the seaming wire will not wear so as to increase the lifetime of the basketball and softball.

BACKGROUND OF THE INVENTION

Referring to FIGS. 2 and 3, the prior art baseball or softball includes a ball core 10, and two covers 30 which are seamed by a seaming wire 20. An edge of each cover 30 is formed with a plurality of wire holes 31 (referring to FIG. 1) for receiving the seaming wire 20.
However in above mentioned structure, the seaming wire 20 protrudes from the surfaces of the covers 30 (referring to FIGS. 2 and 3). Since the seaming wire 20 is easy to wear and thus break so as to affect the lifetime of baseballs or softballs. Furthermore, currently, a lower side of each cover 30 is installed with a filling object 40 so as to form a protrusion. However this increase the wear of the seaming wire 20.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a ball structure used in a baseball or a softball, wherein a plurality of recesses arranged near an edge of each cover; and part of the seaming wire exposing out of the covers will fall into the recesses. Thereby the seaming wire will not wear so as to increase the lifetime of the basketball and softball.
To achieve above objects, the present invention provides a ball structure used in a baseball or a softball which comprises a ball core; two covers enclosing the ball core; the two covers being seamed together by a seaming wire; an edge of each cover being formed with a plurality of wire holes for being passed by seaming wire; a plurality of recesses arranged near an edge of each cover; each recess being formed between a respective one of the wire holes and the edge of each cover; a direction of each recess being identical to the seaming direction of the seaming wire; thereby when the two covers enclose the ball core by the seaming wire; the part of the seaming wire exposing out of the covers fall into the recesses.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows the structure of the prior art baseball and softball.
FIG. 2 shows enclosing structure of the prior art baseball and softball.
FIG. 3 is a cross sectional view along line I-I of FIG. 2.
FIG. 4 is a structure of the cover of the present invention.
FIG. 5 shows the enclosing structure of the present invention.
FIG. 6 is a cross sectional view along line II-II of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to FIGS. 4 to 6, the present invention will be described herein
As shown in FIGS. 5 and 6, the present invention is suitable to be used in basketballs or softballs. The present invention comprises the following elements.
A ball core 10 is included.
Two covers 30 enclose the ball core 10. The two covers 30 are seamed together by a seaming wire 20. An edge of each cover 30 is formed with a plurality of wire holes 31 (referring to FIG. 4) for being passed by using the seaming wire 20.
With reference to FIG. 4, a plurality of recesses 32 are arranged near the edge of each cover 30. Each recess 32 is formed between a respective one of the wire holes 31 and the edge of each cover 30. A direction of each recess 32 is identical to the seaming direction of the seaming wire 20. Thereby when the two covers 30 enclose the ball core 10 by the seaming wire 20 (referring to FIGS. 5 and 6), the part of the seaming wire 20 exposing out of the covers 30 will fall into the recesses 32. Thereby the seaming wire 20 will not wear so as to increase the lifetime of the basketball and softball.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
