  The present invention has been made in view of the background art described above, and an object of the present invention is to provide a ball that is easy to grasp and has a simple structure of an epidermis.

  The present invention is characterized in that the sphere is a ball covered with an epidermis, and the epidermis is configured as an elastic cushion part, or the epidermis is an elastic cushion part on the sphere side. And a skin portion that covers the surface portion side of the cushion portion.

  In the present invention, when the skin body is configured as an elastic cushion portion, it is not necessary to use a conventional supporting member, and the skin body can be manufactured by integral molding or cutting, and the productivity is good. Alternatively, when the skin has a cushion part having elasticity on the side of the sphere and a skin part covering the surface part side of the cushion part, the skin part prevents the cushion part from being worn, the durability is improved, and the skin part is It becomes possible to give various designs to. In the present invention, for example, in the case of a ball game in which a ball is held with a hand, such as a handball, the skin is easily dented, and the ball has an appropriate repulsive force and is easy to grab, and it is easy to throw or catch the ball. become.

  In the present invention, if the hollow portion is provided inside the cushion portion, the joint area with the sphere can be increased and the joint strength can be improved. In the present invention, if the hollow portion is provided between the cushion portion and the spherical body, the skin portion can be easily manufactured. In the present invention, if a cavity is provided between the skin and the sphere, the hardness of the joint of the skin can be softened. By changing the size of the hollow portion, the hardness of the cushion portion can be adjusted, and the amount of depression and the repulsive force when the ball is gripped by hand can be adjusted. In the present invention, when the cushion portion is composed of a plurality of layers made of materials having different hardnesses, the skin body can be easily dented and can also have an appropriate repulsive force.

In the first mode, as shown in FIG. 13, the case where the back surface portion of the cushion portion 9 and the sphere 2 are adhered with the adhesive agent 6 and the case where the skin portion 10 and the surface portion of the cushion portion 9 are adhered to each other with the adhesive agent 11 Both the case of adhering with each other are essential configurations, and the case of adhering the side surface portions of the adjacent skin portions 10 to each other with an adhesive (not shown) is an arbitrary configuration. In the second mode, the case where the side surface portions of the adjacent cushion portions 9 are adhered to each other with an adhesive (not shown) is an essential configuration, and the skin portion 10 and the surface portion of the cushion portion 9 are adhered to each other with the adhesive 11. The case of adhering, the case of adhering the back surface part of the cushion part 9 and the sphere 2 with the adhesive agent 6, and the case of adhering the side surface parts of the adjoining cushion part 9 with each other by an adhesive agent not shown respectively. Arbitrary configuration. As the joining means, the adhesives 6 and 11 and the adhesive not shown are exemplified, but instead of the adhesives 6 and 11 and the adhesive not shown, a joining means such as an adhesive or welding can be applied. is there.

  With reference to FIG. 14, a ball 1 according to Embodiment 13 of the present invention will be described. In the ball 1 shown in FIG. 14, since the plurality of skins 3 are provided with the elastic cushion part 9 and the elastic skin part 10, the skin part 10 prevents wear of the cushion part 9 and durability. Is improved, and various designs can be applied to the skin 10. Since the cushion portion 9 is formed by injection molding, press molding, cutting, or the like, it is not necessary to use a conventional supporting member, and the cushion portion 9 can be easily manufactured. The cushion portion 9 includes a front concave portion 15. The skin portion 10 is provided with a chamfered portion 4 at its peripheral edge, covers the surface portion and the surface side portion of the side surface portion of the cushion portion 9, and the cushion portion 9 is present on the side of the sphere 2 with respect to the side surface portion of the skin portion 10. .

  The front recess 15 between the cushion portion 9 and the skin portion 10 is surrounded by the skin body 3 and the cushion portion 9 to form a hollow portion 16, and when a person grips the ball 1, a recess on the surface portion of the skin body 3 is formed. The ease and repulsion can be adjusted, and the ball 1 has a structure that is easy to grasp, throw, and catch. A material such as a non-woven fabric, which is softer than the cushion portion 9, may be incorporated into the cavity 16 so that the cavity 16 does not sag. The cushion portion 9 may be composed of a plurality of layers made of materials having different hardness.

  Regarding the adhesion of the skin body 3, the following two modes can be considered. In the first mode, as shown in FIG. 14, the case where the side surface portions of the adjacent cushion portions 9 are adhered to each other with an adhesive (not shown) is essential, and the side surface portions of the adjacent cushion portions 9 are Adhesives (not shown) are used for bonding, skin 11 and front surface of cushion 9 are bonded by adhesive 11, and back surface of cushion 9 and sphere 2 are adhesive 6 Each of the case of adhering by and the step of adhering is made arbitrary. In the second mode, both the case where the back surface of the cushion part 9 and the sphere 2 are bonded with the adhesive 6 and the case where the skin part 10 and the surface part of the cushion part 9 are bonded with the adhesive 11 are used. As an indispensable configuration, the case where the side surface portions of the adjacent skin portions 10 are adhered to each other with an adhesive agent not shown and the case where the side surface portions of the adjacent cushion portions 9 are adhered to each other with an adhesive agent not shown Both the case and the case have arbitrary configurations. As the joining means, the adhesives 6 and 11 and the adhesive not shown are exemplified, but instead of the adhesives 6 and 11 and the adhesive not shown, a joining means such as an adhesive or welding can be applied. is there.
