Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

referring to fig. 3 and 4, a first embodiment of the softball of the present invention includes a core unit 2, a body unit 3 covering the core unit 2, and a cover unit 4 fixed to the body unit 3. It should be noted that, since the baseball and softball have similar structures and are only based on the difference in size, and the size can be followed by the players in the related field in response to the official specification of the regular game, the detailed description of the technical contents and the explanation of the implementation effect will be focused on in the description of the present embodiment, and the additional description of the related contents of the difference between the baseball and softball will not be provided.

The spherical center unit 2 comprises a spherical cork body 21 and a rubber layer 22 covering the cork body 21. The core unit 2 has a certain weight and a relatively stable shape, and cooperates with the characteristic that the rubber layer 22 can absorb impact force by using its own elasticity, so that the core part of the first embodiment is stable, and irreversible deformation caused by strong impact force during use is avoided, thereby stabilizing the overall shape and the distribution of the gravity center position.

the main body unit 3 includes a laminate 31 formed by repeatedly winding a yarn 310 around the outside of the core unit 2, and a film layer 32 formed by solidifying a liquid rubber resin and attached and fixed to the outside of the laminate 31. The multilayer body 31 occupies the largest proportion of the first embodiment, and is a main structure constituting a spherical body. The yarn 310 can be formed into a structure having elasticity and maintaining a spherical shape after being accumulated to a certain thickness in the case of repeated close winding, and a desired use feeling can be maintained as long as the structure of the laminate 31 is not damaged or moisture is permeated.

The liquid rubber resin solution is preferably directly impregnated into the liquid rubber resin solution together with the core unit 2, so that the liquid rubber resin can be impregnated into the yarn 310, and other methods such as direct spraying, staining, and the like can be used in practical implementation, and the method is not limited to the above method. But in order to match the production line processing requirements. Next, the applied liquid rubber resin. The liquid rubber resin is dried at a temperature of 80-100 ℃ to accelerate the molding of the film 32, so that the liquid rubber resin is matched with the production line operation of a conveyor belt. However, the liquid rubber resin can be naturally dried at room temperature for about 1 minute to form the film layer 32. The yarn 310 is impregnated with the adhesive film layer 32 of the main body unit 3, whereby the adhesive film layer 32 is prevented from falling off from the laminate 31.

As shown in fig. 5, the skin unit 4 includes two leather sheets 41 with the same shape, and a sewing thread 42 sewn to the periphery of the leather sheets 41 to make the leather sheets 41 cover the main body unit 3. The leather pieces 41 together form a spherical outer surface, and the leather pieces 41 are sewn together with the sewing thread 42, thereby forming an outer coating structure that covers the main unit 3.

Referring back to fig. 3 in conjunction with fig. 5, since the shape of the skin unit 4 is mainly formed by two leather pieces 41, there is a gap through which moisture passes between the leather pieces 41 although they are sewn by the sewing thread 42. The lamination body 31 is coated by the adhesive film layer 32, so that the lamination body 31 can be protected from moisture by utilizing the waterproof property of the adhesive film layer 32, and the shape, weight and gravity center position of the lamination body 31 are prevented from being changed due to water absorption, even the whole elastic coefficient is prevented from being changed, so that the whole spherical shape, gravity center position and elastic coefficient of the first embodiment are maintained. In addition, since the adhesive film layer 32 is fixedly attached to the laminate 31, relative movement between the adhesive film layer 32 and the laminate 31 does not occur, and a good feeling in use can naturally be maintained even when the overall bondability is relatively stable. Therefore, the overall shape and the center of gravity of the first embodiment are not easily affected by the normal use actions of striking, throwing, catching, etc., and even the external environment, and the combination stability of each structural layer is high, so that the first embodiment has a long service life in response to long-time and high-strength use.
