Abstract

An object of the present invention is to provide a ball for ball games that completely solves the problem of valve drop during use of the ball. SOLUTION: The ball for ball game comprises a ball body (2), a tube (3) in the ball body, and a valve (5) having an insect rubber (4) in the center, and one of the valves is air of the ball body. At the mouth there is a pair of integral flanges (6, 7) bonded to the inner surface of the ball body and the other bonded to the outer surface of the tube, passing through the valve neck (9) between said pair of flanges, and A reinforcing member (11) extending to the left and right below and adjacent to one of the flanges bonded to the inner surface of the ball body, and having both side edges of the reinforcing member with a hexagonal skin piece adjacent thereto; One of the flanges of the valve is sewn together so as to be held from below by the reinforcing member.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved ball for ball games, and more particularly to a ball for ball game, for example, a ball for handball, which prevents a valve from dropping when the ball is used.

[0002]

2. Description of the Related Art A first ball for ball games of this kind is composed of a ball body 2 formed by sewing hexagonal skin pieces 1, a tube 3 in the ball body, and an inner surface of the tube at an air port of the ball body. And a valve 5 having an insect rubber 4 in the center (see FIG. 1). The second ball for ball game is adhered to the inner surface of the ball body 2 at one of the air holes of the ball body 2 and the tube 3 in the ball body, the ball body 2 having the same structure as the first ball game ball. ,
The other is an integral flange 6 glued to the outer surface of the tube 3
And a valve 5 having an insect gum 4 in the center (see FIG. 2). The third ball is essentially the same as the structure of the second ball, except that one flange 6 is adhered to the inner surface of the ball body 2 and is further attached to the ball body 2 on both sides of the bulb. Sew as shown by (see FIG. 3).

[0003]

In the first ball for ball games, the bulb sometimes comes off from the adhesive surface during use of the ball and falls, and when this occurs, it is no longer possible to inject air. Also, it is impossible to replace or repair the insect rubber. The second ball for ball use does not release the valve from the tube during use of the ball, but may come off the ball body. Then, because the fixing of the valve to the ball body is lost or the valve is displaced from the air port, the air injection needle cannot be pierced from the air port of the main body to the insect rubber, and replacement or repair of the insect rubber is performed. Is also impossible. Although the third ball is designed to solve the above-mentioned disadvantages of the second ball, the sewn portion may be torn during use, and the disadvantage that the valve comes off and falls is still present. It existed and was not a radical solution. SUMMARY OF THE INVENTION It is an object of the present invention to provide a ball for ball games which completely solves the problem of valve drop during use of the ball.

[0004]

SUMMARY OF THE INVENTION According to the present invention, there is provided a ball body formed by sewing hexagonal skin pieces, a tube in the ball body, and one at an air port of the ball body. A ball having a pair of integral flanges bonded to the inner surface of the ball body and the other bonded to the outer surface of the tube, and a valve having insect rubber at the center thereof, wherein the valve between the pair of flanges A hexagonal skin having a reinforcing member extending laterally below and adjacent to one of the flanges which is passed through the neck and adhered to the inner surface of the ball body; This is achieved by providing a ball for ball use, wherein the ball is sewn together with one piece so that one flange of the valve is held from below by the reinforcing member.

In a preferred embodiment, the reinforcing member is preferably rectangular in shape and made of synthetic leather. Preferably, the inner surfaces of both ends of the reinforcing member are adhered to the inner surface of the ball body so as to securely hold one flange of the valve.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 4, a preferred embodiment of the ball for ball games according to the present invention will be described. The ball for a ball game, that is, a ball for handball according to the present invention comprises a ball body 2 formed by sewing hexagonal skin pieces 1, a tube 3 in the ball body, and a valve 5 having an insect rubber 4 in the center. The valve 5 has a pair of integral flanges 6 and 7, one of which is bonded to the inner surface of the ball body 2 at the air port of the ball body 2 and the other flange 7 is bonded to the outer surface of the tube 3. Is done. The valve 5 forms a valve neck 9 between a pair of flanges 6 and 7, through which a reinforcing member 10 of synthetic leather, for example, is passed, and the reinforcing member 1 is formed.
Reference numeral 0 denotes a rectangular shape, which extends left and right adjacent to and below one of the flanges 6 bonded to the inner surface of the ball body 2. The side edges of the reinforcing member 10 are sewn together with the hexagonal skin pieces 1 adjacent thereto as shown at 11 to hold one flange of the valve from below. Reinforcing member 10
The inner surfaces of both ends are preferably glued to the inner surface of the ball body 2 as shown at 12, which helps to hold one flange of the valve securely.

[0007]

Since the ball for ball games according to the present invention is constructed as described above, even if one of the flanges of the bulb comes off from the bonding surface of the ball body due to impact or other physical factors during use, the ball under the ball is not affected. The side reinforcing member can prevent the valve from falling down.
