Abstract

A softball comprises a core and a jacket. The core is made of polyurethane material, and the jacket is soft leather. A waterproof isolation layer is arranged between the core and the jacket. The isolation layer is formed by winding yarns in layers and impregnating with adhesive. The isolation layer is formed by winding yarns in layers and impregnating with adhesive, and has waterproof and water vapor-proof properties, thereby preventing the core from being damaged by water or water vapor.

Description

Softball

[technical field]

The utility model is about a kind of softball.

[background technology]

The softball 1 that uses as shown in Figure 1 at present, be made of a ball core 11 and a football shirt 12, this ball core 11 mainly is made by cork or foaming materials such as (PU), and football shirt 12 then is a moccasin, this football shirt 12 is in the mode of making ball core 11 to be coated, and forms a complete softball 1 whereby.Softball 1 is because of different fields of employment, and different standards is arranged, organize ordered standard as management such as ASA, US SSA control, the volume size aside from, single with regard to compressive resistance, have at least its resistance to compression value of requirement must not be lower than the regulation of 3751bs (pound), 4001bs (pound), 5001bs different sizes such as (pounds).Therefore the producer of softball 1 can sell on market in order to make its softball that produces 1, the softball 1 of its manufacturing all must be conformed to the standard, and softball 1 when using in this way at rainy day or the higher environment of moisture, this rainwater or aqueous vapor can enter softball 1 inside by football shirt 12, and ball core 11 is soaked, because ball core 11 is rich stronger water imbibitions, therefore can make a large amount of moisture content of ball core 11 absorption, after ball core 11 has adsorbed suitable moisture content, will cause the weight of softball 1 to increase, can cause the resistance to compression value of softball 1 and rebound coefficient etc. to reduce greatly what is more, and become a softball 1 that does not meet standard, so the softball 1 that this ball core 11 is dipped into water is considered as usually damaging and must abandons.

The softball of commonly using 1 is except having the drawback that suffers water enchroachment (invasion) in use, even softball 1 is when depositing, as long as this place of depositing is the higher environment of humidity, still can make moisture content enter softball 1 inside by football shirt 12, can cause ball core 11 to make moist equally, and the resistance to compression value of softball 1 and rebound coefficient etc. are reduced greatly, and then become softball 1 for damaging.Therefore, how to make softball 1 avoid being subjected to the infringement of water or aqueous vapor, for the softball manufacturer a big problem to be solved is arranged in fact.

[utility model content]

The purpose of this utility model is to provide a kind of softball, can avoid the ball core invaded by water or aqueous vapor, avoids softball to be damaged because of the infiltration of water or aqueous vapor, and then prolongs the service life of softball, improves the use effect of softball.

In order to achieve the above object, the utility model provides a kind of softball, this softball includes ball core and football shirt, it is characterized in that: this ball core is made by polyurethane material, this football shirt is a moccasin, the separation layer of one waterproof is set between ball core and football shirt, this separation layer be by yarn with the lamination mode twine and the impregnation agent formed, by this separation layer is to be twined by the yarn lamination to flood viscose glue again, and have the characteristic of waterproof and anti-aqueous vapor, can avoid the ball core invaded by water or aqueous vapor whereby and cause the damage of softball.

Described softball, wherein this yarn is polyester fiber (polyester).

Described softball, wherein this separation layer is into tight stickup with the ball core.

Described softball, wherein this separation layer is into tight stickup with football shirt.

In sum, softball of the present utility model, by a separation layer is set between ball core and football shirt, and to utilize this separation layer be to be twined by the yarn lamination to flood viscose glue again, reach the characteristic of preventing aqueous vapor and have waterproof, can avoid the ball core invaded by water or aqueous vapor, cause the force value of softball to change, and the shortcoming that causes the damage of softball to use takes place; Setting by above-mentioned separation layer, can improve the service life and use effect of the utility model softball, in addition, it will be further appreciated that, because separation layer is made of yarn and jelly, so softball of the present utility model when using, still can be sent clear and melodious sound when hitting then, also can improve the use effect of the utility model softball whereby.

[specific embodiment]

For the effect that is easy to understand structure of the present utility model and can reach, conjunction with figs. is described as follows now:

As shown in Figure 2, softball 2 of the present utility model mainly includes ball core 3, separation layer 4, and football shirt 5.

At first, see also shown in Fig. 2,3,4, this ball core 3 mainly is made by polyurethane (polyurethane), makes ball core 3 have preferable crushing resistance whereby, and can make softball 2 meet the standard of compressive resistance.

This separation layer 4; be by yarn 41 in ball core 3 outer peripheral edges with the lamination canoe; form the certain thickness thread layers of tool; this yarn 41 is to implement by polyester fiber (polyester); more can improve the water proofing property of separation layer 4; ball core 3 with the tool thread layers is dipped in the jelly again; fill up by jelly in the space of thread layers, and can have adherence, paste closely and separation layer 4 is formed with ball core 3 and football shirt 5 respectively by jelly; and then separation layer 4 and ball core 3 are become one; in addition, fill up the space of thread layers when jelly after, this separation layer 4 promptly has water proofing property; whereby, this separation layer 4 can protect ball core 3 to avoid being subjected to the intrusion of water.

Football shirt is made by moccasin or plastic foam material (eva), and with suture way separation layer 4 and ball core 3 is coated wherein.

The utility model is when implementing, be to make ball core 3 with the foaming of polyurethane (polyurethane) material earlier, the compressive resistance value that makes ball core 3 have whereby meeting standard, again in the appearance of ball core 3 with polyester fiber (polyester) yarn, twine formation one thread layers in the lamination mode, the ball core 3 that is wound with thread layers is dipped in the jelly, make ball core 3 peripheries form a separation layer 4 whereby, in separation layer 4 appearances football shirt 5 is sewed up at last, football shirt 5 is coated separation layer 4 and ball core 3, promptly finish softball 2 of the present utility model.

Effect of the present utility model is, by between football shirt 5 and ball core 3, separation layer 4 being set, this separation layer 4 is owing to be made of yarn 41 and jelly, therefore has preferable water proofing property, whereby, when softball 2 of the present utility model is deposited in the higher environment of humidity or run into water in being used, can be by the isolation of separation layer 4, avoid the intrusion of 3 rounds aqueous vapors of ball core or water, and then can improve the service life and use effect of the utility model softball 2.In addition, it will be further appreciated that,,, more can improve the use effect of the utility model softball 2 whereby so softball of the present utility model 2 when using, still can be sent clear and melodious sound when hitting then because separation layer 4 is made of yarn 41 and jelly.

In sum, the utility model really can have been reached the purpose and the effect of institute's demand by above-mentioned structure.
