Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball for ball games, and more particularly, to an elastic spherical hollow body filled with compressed air and a plurality of polygonal leather sheets covering the spherical hollow body. The present invention relates to a ball for a ball game such as a soccer ball having a skin layer composed of:

[0002]

2. Description of the Related Art A ball for a ball game, such as a soccer ball, usually has a structure in which a skin layer composed of a plurality of polygonal leather sheets is arranged on the surface of the spherical hollow body. The skin layer,
A peripheral portion of the polygonal leather sheet is overlapped with a peripheral portion of another adjacent polygonal leather sheet, and a plurality of small holes for sewing are provided at regular intervals in the overlapped portion, and a suture thread is passed through the small hole. The overlapping portions of the adjacent polygonal leather sheets are sewn together to form a spherical shape as a whole. Then, a ball for ball game is manufactured by storing the spherical hollow body inside the spherical skin layer.

[0003] By the way, in order to improve the controllability and grip of the ball for ball games, it is usually necessary to deepen a groove of a stitching line portion formed between adjacent sheets. Or the leather sheet must be sutured with a large diameter thread. Therefore, the suturing operation has to be performed by hand.

[0004]

As described above, in the case of the above-mentioned ball for ball games, the overlapping portion of the peripheral portions of a plurality of polygonal leather sheets is manually sewn using a suture thread to form the skin layer. Therefore, there are the following problems. That is, the proportion of the process of forming the skin layer in the process of manufacturing the ball for ball games is high, and the workability is reduced. Due to manual work, variations in the fastening force due to stitching occur, and it is not possible to obtain a ball of good form,
Also, the controllability and grip required for a ball for ball games cannot be sufficiently secured. Furthermore, the ball for ball games is provided with a backing layer made of cloth or the like on the back surface of the polygonal leather sheet forming the skin layer,
Since the polygonal leather sheet and the backing layer are integrally sewn, the suturing operation becomes difficult. And other issues.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and its purpose is to simplify the sewing of the peripheral portion of the polygonal leather sheet forming the skin layer, It is an object of the present invention to provide a ball game ball such as a soccer ball that can reduce variation in fastening force at the time of suturing and can form a good suturing line.

[0006]

A ball game ball according to claim 1 of the present invention as a means for solving the above-mentioned problem is a ball-shaped hollow body having compressed elasticity filled with compressed air. A ball game ball having a skin layer composed of a plurality of polygonal leather sheets covering a body, wherein the skin layer overlaps the peripheral edges of adjacent polygonal leather sheets, and is formed by sewing the overlapped portions. The overlapping portions of the adjacent polygonal leather sheets are stitched with a plurality of staples.

[0007] The ball for ball game of claim 2 is the ball of claim 1.
In the invention according to the invention, a polygonal hollow leather sheet having elasticity in which compressed air is enclosed, and a skin layer comprising a plurality of polygonal leather sheets covering the spherical hollow body, wherein the skin layer is adjacent to the polygonal leather sheet In the ball for ball game which is formed by superposing the peripheral portions of
The overlapping portion of the adjacent polygonal leather sheets is sewn with a plurality of male and female stoppers.

The ball for ball game of claim 3 is the ball for ball game of claim 1.
Alternatively, in the invention according to the second aspect, a plurality of stapling lines by the staples or the fasteners are provided, and the positions of the staples in the plurality of rows are arranged in a crossing manner.

Here, the ball for the ball game is a variety of balls such as a soccer ball, a volleyball, and a handball.
A spherical hollow body having elasticity filled with compressed air, and a skin layer composed of a plurality of polygonal leather sheets covering the spherical hollow body, the peripheral layer of the polygonal leather sheet adjacent to the skin layer is provided. It refers to a ball formed by overlapping and suturing the overlapped portion. The leather sheet forming the skin layer refers to a sheet made of synthetic leather, natural leather, cloth having the same properties as other leathers, and the like. As the staple, a metal or synthetic resin binding needle, for example, a stapler (trademark) needle can be used. In addition, a general rubber tube can be used as the spherical hollow body.

In the ball for ball games of the present invention, a plurality of polygonal leather sheets formed by attaching a backing layer made of cloth or the like to the back surface are prepared, and the peripheral edges of adjacent polygonal leather sheets are overlapped. Then, the overlapped portion is stitched with a plurality of staples or fasteners to form a spherical skin layer as a whole, and then the skin layer is turned over, and a spherical hollow made of a rubber tube or the like is provided inside the skin layer. It can be produced by enclosing the body.

[0011]

As is apparent from the above description, according to the ball for ball games of claim 1 or 2 of the present invention, the overlapping portion of the adjacent polygonal leather sheets is formed by a plurality of staples or male and female shapes. Since the skin layer is formed by suturing with a fastener, the variation in the tightening force at the time of suturing can be reduced, the suturing operation can be simplified, and the ball can be manufactured because it can be further mechanized. This has the effect that the time can be reduced. According to the ball for ball games of the third aspect, a plurality of suturing lines by the staples or the stoppers are provided, and the positions of the staples in the plurality of rows are arranged in an intersecting manner. This has an effect that the strength can be easily formed by a simple operation.
