とに存するものである。The present invention was created with the aim of simplifying the manufacturing process and enabling mass production, as well as providing an exercise ball that is comfortable to use. is pasted with latex to form a reinforcing layer, and a skin is pasted on the outer surface of this reinforcing layer.In addition, in the manufacturing method, a hollow spherical tee is formed.
A reinforcing layer is formed by filling a predetermined amount of air into this chi soup, and then pasting pieces of cloth with latex on the surface of the chape without any gaps, and then forming a border on the outer peripheral surface of this reinforcing layer. The method consists in forming the outer layer at the border and attaching the skin along this boundary.
以下、本発明の一実施例を図面の簡単な説明する。図に
おいて１は、ゴム製の球体状チー−ブである。このチ、

線に沿って若干突出させた突条を一体形成して設けられ
ろ。このチューブ１内には所要圧力の空気を充填する。Hereinafter, one embodiment of the present invention will be briefly described with reference to the drawings. In the figure, 1 is a spherical tube made of rubber. This chi,
- The plate 1 is provided with ridges that are integrally formed on its surface and slightly protrude along the meridian and latitude lines, which are provided at appropriate intervals. This tube 1 is filled with air at a required pressure.
この空気の充填はチューブ１が内部の空気圧の交め膨ら
んで大となることなく、かつ、布片２を貼着できる程度
の圧力としてボールを真球なものとしている。This filling of air prevents the tube 1 from expanding due to the internal air pressure, and at the same time, the pressure is sufficient to attach the piece of cloth 2 to make the ball a perfect sphere.
次いで、仁のチェー１１０表面に略台形状の布片２を互
いの縁部が重なり合うよう隙間なく、ラテックス３にて
貼設する。このラテックス３は天然、合成いずれでも良
いが、天然ラテックスの方が接着性、弾力性に優れる。Next, a substantially trapezoidal piece of cloth 2 is pasted on the surface of the chain 110 with latex 3 so that their edges overlap without any gaps. This latex 3 may be either natural or synthetic, but natural latex has better adhesiveness and elasticity.
布片２は全球面を１２等分した略台形状を呈し、かつこ

友布片２で、上部補強層は１８分割し比布片２で形成し
ても良い。The cloth piece 2 has a substantially trapezoidal shape, which is obtained by dividing the entire spherical surface into 12 equal parts, and these cloth pieces 2 are of the same shape.From the point of reinforcement, the cloth piece 2 is doubled and the cloth piece 2 and the latex 3 are used for laminated reinforcement. layer 4t
- form. 12. The piece of cloth 2 is not limited to nine pieces divided into the whole sphere f1';a, but is also a piece of cloth which is divided into six equal parts and the tiger one is further divided into three, that is, the whole sphere is divided into t-18 pieces. Further, the lower reinforcing layer of the reinforcing layer 4 may be formed by dividing into 12 pieces of cloth 2, and the upper reinforcing layer may be formed by dividing into 18 pieces of cloth 2.

後の補強層４外面には、ゴムにて表皮の境界線に等しい
低い突条、すなわち、境界部５が形成される。Next, the reinforcing layer 4 is formed, the nine tubes 1 are placed in a full line drawing frame, and a line is drawn approximately in the middle of the portion where adjacent cloth pieces 2 overlap among the cloth pieces 2 stuck to the tube 1. Furthermore, a rubber plate is pasted on this line. Thereafter, the rubber plate is placed in a mold whose inside has a perfect spherical shape with a desired diameter, and by pressurizing air into the tube 1, the reinforcing layer 4t11 is brought into close contact with the inside of the frame, and the rubber plate is subjected to a heat vulcanization treatment. At this time, a rubber plate is attached to the formwork and a shallow groove is formed in the part corresponding to the boundary part 5 of the outer skin, so heat vulcanization is performed and the outer surface of the reinforcing layer 4 after the outer skin is covered with rubber. A low protrusion, ie, a border 5, is formed that is equal to the border of the epidermis.

製造時間の短縮が図れる。However, this boundary part 5 is created by omitting the rubber plate adhesion process and the heat vulcanization process, and placing the tube 1 on which the reinforcing layer 4 has been formed into a tube form, with a part of the reinforcing layer 4 protruding shallowly and recessed. It is also possible to form holes in this way, and the number of man-hours and manufacturing time can be reduced.

Twelve approximately trapezoidal skins 6 are pasted along these ridges, and then heated to 60°C to 0°C and pressed from the outside.
form a ball. Of course, one of the thirteen skins 6 must be provided with a pulp protrusion in the center from which the valve emerges. The number of skins 6 is not limited to 12 like the cloth pieces 2, and it goes without saying that a spherical surface divided into 18 parts may also be used.
ま几、表皮６の境界は、補強層４に貼着し、た布片２の
重複部であって４枚若しくは３枚の布片２にて形成され
ている為に丈夫であり、使用時に表皮６の境界部５より
裂ける虞れはない。The boundary between the outer skin 6 and the outer skin 6 is an overlapped part of the cloth pieces 2 attached to the reinforcing layer 4, and is strong because it is formed by four or three cloth pieces 2. There is no risk of tearing from the boundary part 5 of the epidermis 6.
このように構成し、中空球状チューブ１外局面に布片２

損うことなく図れるものである。With this structure, a piece of cloth 2 is attached to the outer surface of the hollow spherical tube 1.
By adhering T latex 3 to form a reinforcing layer 4, it is possible to improve the strength of the ball and simplify the manufacturing process without impairing the feeling of use of the ball.

友硬さのものとなってしまいバレーボールには不適当で
ある難点を有してい友。T-poles existed, but these had a reinforcing layer formed by thread wrapping, which increased man-hours and working time, and lacked elasticity, resulting in a stiffness similar to that of soccer and basketball. A friend who has the disadvantage of being unfit for volleyball.

も使用感を損うことがないのである。In order to improve the feeling of use, we manufactured a hollow sphere from a brittle material, attached pieces of cloth to the hollow sphere with adhesive to form the entire bag, and attached a spherical tube to the bag. In addition to charging, a ball with a free material such as Merck interposed between the tube and the bag body is also provided.9 However, as mentioned above, it has one point that increases the number of man-hours and work time. According to the present invention, since the cloth piece 2 is directly attached to the tube 1VC with the latex 3, it is possible to reduce the number of man-hours and work time, and since the cloth piece 2 is attached with the latex 3, elasticity can be improved. A release agent such as Merck's is interposed between the reinforcing layer made of the conventional bag and the cheese, so that the usability is not impaired even when compared to T-balls.
以上説明し友ように、本発明によれば使用感を損うこと

提供できる等の優れた効果を奏するものであり、特に、
バレーボール競技用ボールとして最適なものである。As explained above, the present invention has excellent effects such as simplifying the manufacturing process and shortening the working time without impairing the usability, and being able to provide the product at a low cost.
This is the perfect ball for volleyball.
