FIG. 6 is a cross-sectional view showing a golf ball disclosed in Patent Document 1.

  A ball 1 according to Embodiment 1 for carrying out the invention will be described with reference to FIGS. The ball 1 shown in FIGS. 1 and 2 is provided with a self-adhesive body 9 formed by supporting a self-adhesive material with a reinforcing member on the surface side of the ball body 41. In the case of the ball game to be gripped with the ball 1, when the person grips the ball 1, the self-adhesive body 9 is easily caught on the finger of the person who grips the ball 1, the surface of the ball 1 becomes difficult to slip, and the ball 1 is easy to grip.

  In FIGS. 1 and 2, the ball body 41 is exemplified by a structure in which the inner sphere 2 is covered with the epidermis 3. However, the inner sphere 2 and the epidermis 3 are integrated so that no difference can be seen in the cross section. Either a structure, a structure including only the epidermis 3 without the inner sphere 2, or a structure including only the inner sphere 2 without the epidermis 3 can be applied. That is, a structure in which the inner sphere 2 is covered with the epidermis 3, a structure in which the inner sphere 2 and the epidermis 3 are integrated so that no difference is seen in the cross section, and only the epidermis 3 is absent without the inner sphere 2. And the structure consisting only of the inner sphere 2 without the skin body 3 can be uniquely defined as the ball body 41.

  In FIGS. 1 and 2, since the self-adhesive body 9 is provided on the surface side of the epidermis 3, when a person grasps the ball 1, the finger of the person's hand is easily caught on the self-adhesive body 9. It becomes difficult to slip even when sweating, the surface of the ball 1 is easy to grasp and throw and easy to catch, and the person using the ball 1 does not have to hold the ball 1 firmly. Moreover, since the self-adhesive body 9 has a structure in which the self-adhesive material is supported by the reinforcing member, the reinforcing member prevents the self-adhesive material from being damaged, and the durability of the self-adhesive body 9 is improved. On the other hand, if the self-adhesive material, which is a soft member, is provided on the surface side of the epidermis 3 without being supported by the reinforcing member, the self-adhesive material is likely to be damaged or damaged due to the use of a ball. Become. The self-adhesive material used for the self-adhesive body 9 has the property of adhering to human hands, and when dirt or the like adheres to the surface of the self-adhesive material, the dirt is removed by washing with water or a cleaner containing an abrasive and dried. By this, it is a member having the characteristic that the adhesive strength is restored.

  1 and 2 exemplify a structure in which the self-adhesive body 9 is provided across the surface of the surface portion 4, the surface of the chamfered portion 6, and the surface of the peripheral wall portion 5. A structure provided on a part of the surface, the entire surface of the surface portion 4, the surface of the surface portion 4 and the surface of the chamfered portion 6 is also applicable. However, as shown in FIGS. 1 and 2, if the self-adhesive body 9 has a structure provided over the surface of the surface portion 4, the surface of the chamfered portion 6, and the surface of the peripheral wall portion 5, Can prevent turning up.

  As a reinforcing member, fibers are used as a base material such as a perforated body, a net-like body, artificial turf, mohair or carpet provided with a number of holes in a thin flat object such as nonwoven fabric, woven fabric, knitted fabric, sheet or film. Etc., various warps and many wefts stacked one above the other, many warps arranged side by side, many wefts arranged side by side, etc. Things are applicable. For example, when a non-woven fabric is used as the reinforcing member, the non-woven fabric is impregnated with the self-adhesive material, so that the non-woven fabric is wrapped in the self-adhesive material and the self-adhesive material is supported. This is a structure in which is supported by a reinforcing member. In short, the structure in which the self-adhesive body 9 supports the self-adhesive material with the reinforcing member is obtained by wrapping the non-woven fabric with the self-adhesive material and supporting the self-adhesive material.

  As the self-adhesive material, urethane-based, silicone-based, styrene-based gel, self-adhesive material coating, and double-sided tape can be applied. Gel has high durability of adhesive performance. Self-adhesive coating is highly productive and highly productive. Double-sided tape has good workability. As a method of fixing the self-adhesive body 9 to the surface side of the epidermis 3, an adhesive, a double-sided tape, and potting can be considered, but is not limited thereto. In any case, the self-adhesive body 9 does not peel off from the ball body 41 when a person throws the ball 1 while the self-adhesive body 9 touches the hand. Further, if the skin 3 and the self-adhesive body 9 are made of thermoplastic resin and similar materials, the skin body 3 and the self-adhesive body 9 can be fused to each other and firmly fixed.

  As shown in FIGS. 1 and 2, in the structure of a bonded ball in which a plurality of skin bodies 3 are attached to each other, when the plurality of skin bodies 3 are attached to each other, the outer wall surfaces of the peripheral wall portion 5 are mutually attached. It is fixed by welding or an adhesive, so that water such as water and sweat hardly permeates the inner sphere 2 from the boundary of the plurality of epidermis bodies 3 and does not easily peel off from the inner sphere 2. If a valley portion based on the chamfered portion 6 is formed at the boundary between adjacent epidermis bodies 3, the valley portion is handed and the ball 1 is easily grasped. Further, the valley portion based on the chamfered portion 6 can make the appearance of the ball 1 hand-sewn. Further, in addition to welding of the peripheral wall portion 5 or fixing by an adhesive, the back surface of the peripheral wall portion 5 is fixed to the surface of the internal sphere 2 by welding or adhesive, or the peripheral wall portion 5 is fixed without being welded or by adhesive. Even if the back surface of the surrounding wall part 5 is fixed to the surface of the internal sphere 2 by welding or an adhesive while being in contact with each other without being applied.

  The inner sphere 2 is made of a soft material made of resin or rubber, and has a sphere or ellipsoid or similar shape. In addition to a sphere, a sphere or ellipsoid having a flat surface like a truncated icosahedron or similar Shape, a structure in which a thread is wound around the surface of the inner sphere 2, a structure in which a thread is not wound around the surface of the inner sphere 2, a hollow structure in which the inside of the inner sphere 2 can be taken in and out and is expandable, the inner sphere 2 Either a hollow structure in which the inside of the inside is sealed so that air cannot be taken in or out, or a non-hollow structure in which the inside of the internal sphere 2 is filled with a cushioning material can be applied.

  Although the epidermis 3 has shown a hexagon in FIG. 2, even if it is shapes other than a hexagon, it is applicable similarly. The skin 3 is formed by injecting a soft material made of resin or rubber into a mold such as injection molding, press molding, vacuum molding, or blow molding, and the surface portion 4, the peripheral wall portion 5, the chamfered portion 6, and the cavity portion 7 are overhanged. The structure is formed integrally with the portion 8.

  The surface portion 4 is the surface of the ball main body 41 and is a portion on the side where a human hand touches. The chamfered portion 6 is configured to be removed so that the ridge angle between the surface portion 4 and the peripheral wall portion 5 becomes a flat surface or a curved surface. Note that either a configuration in which the chamfered portion 6 is extended to a portion where it intersects the back surface of the epidermis 3 or a configuration in which the chamfered portion 6 is not provided is applicable. In this specification, the back side of the epidermis 3 means the side of the inner sphere 2, and the front side of the epidermis 3 means the side touched by a person.

  The overhanging portion 8 extends from the peripheral wall portion 5 toward the center portion of the epidermis 3 and is separated from the surface portion 4 with a space. That is, by providing the overhanging portion 8 on the back side of the epidermis 3, when the overhanging portion 8 is bonded to the inner sphere 2 as shown in FIG. 2, the area to be bonded to the inner sphere 2 is increased. Adhesive strength increases.

  1 and 2, the self-adhesive body 9 can be replaced with the self-adhesive material 28 supported by the reinforcing member as the skin 3 shown in FIGS. 9 to 17. When the self-adhesive body 9 is replaced with the self-adhesive material 28 in this way, the self-adhesive material 28 is impregnated on the surface side of the skin body 3, and the skin body 3 becomes a reinforcing member for the self-adhesive material 28.

  The ball 1 according to the second embodiment for carrying out the invention will be described with reference to FIG. The ball 1 shown in FIG. 3 is provided on the surface side of the epidermis 3 as a region where the adhesive installation part 10 is recessed from the surface of the epidermis 3, and a self-adhesive material is supported on the adhesive installation part 10 by a reinforcing member. Since the self-adhesive body 9 is provided, the periphery of the self-adhesive body 9 is surrounded by the surface of the epidermis 3, so that the self-adhesive body 9 is difficult to peel off. In addition, the adhesion | attachment installation part 10 is applicable also in the structure provided in the surface side of the epidermis 3 as an area | region divided by the convex part protruded from the surface of the epidermis 3.

  The ball 1 according to the fifth embodiment for carrying out the invention will be described with reference to FIG. The ball 1 shown in FIG. 8 has a structure of a sewing ball in which a plurality of skin bodies 3 are stitched together with a sewing thread 26, and a plurality of skin bodies 3 and self-adhesive bodies 9 are sewn together rather than a pasted ball. Therefore, the bonding strength between the plurality of skin bodies 3 and the self-adhesive body 9 is increased, and the skin body 3 and the self-adhesive body 9 are not easily peeled off. Further, since the sewn skin 3 is broken or the sewing thread 26 is broken, the structure cannot be peeled off, so that the bonding strength is high. In FIG. 8, a plurality of skin bodies 3 are formed into a sheet shape with a self-adhesive body 9 provided on a surface that is die-cut from a raw fabric into a predetermined shape. In this state, the self-adhesive bodies 9 provided in the plurality of skin bodies 3 are overlapped with each other, and the end portions of the superimposed self-adhesive bodies 9 and the end portions of the plurality of skin bodies 3 are sewn with the sewing thread 26. After being assembled, the structure in which the plurality of skin bodies 3 are spread and covered with the inner sphere 2 so that the self-adhesive body 9 is on the front side is illustrated.

  When a plurality of skin bodies 3 are covered with the inner sphere 2 in this way, the end portions sewn with the sewing thread 26 of the skin body 3 constitute the peripheral wall portion 5 of the skin body 3, and the sewing thread 26 of the self-adhesive body 9. The end parts sewn together constitute the peripheral wall part of the self-adhesive body 9. The epidermis 3 can be applied to either a single layer or multiple layers. The self-adhesive body 9 is bonded to the epidermis 3 with an adhesive not shown. Between the skin 3 and the self-adhesive 9, a printed layer (not shown) that represents the logo of the manufacturer of the ball 1 or the design of the ball 1 may be provided. Thus, when a printing layer is provided between the epidermis 3 and the self-adhesive 9, the epidermis 3 can be used in a period prior to bonding the epidermis 3 and the self-adhesive 9 with an adhesive. A printed layer expressing the manufacturer's logo or the design of the ball 1 is applied on the surface side. Thereafter, the self-adhesive body 9 is adhered to the surface side of the epidermis 3.

  The self-adhesive body 9 in FIG. 8 can be applied by replacing it with the self-adhesive material 28 supported by the reinforcing member as the skin 3 shown in FIGS. When the self-adhesive body 9 is replaced with the self-adhesive material 28 in this way, the self-adhesive material 28 is impregnated on the surface side of the skin body 3, and the skin body 3 becomes a reinforcing member for the self-adhesive material 28.
