Title:
BALL
Document Type and Number:
Japanese Patent JP2016221117
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ball which can be easily gripped.SOLUTION: A ball is formed by: bonding plural pieces of cuticle bodies 3 formed of a material which hardly slips, such as a soft resin, a rubber, and a foam thereof, to a sphere 2 with an adhesive agent 6 to cover the whole body of the sphere 2, and rear side recessed parts 5 serve as hollow parts 7 surrounded by the cuticle body 3 and the sphere 2. When a user grips the ball 1, adjustment between ease of being dented on surface parts of the cuticle bodies 3 and repulsion can be achieved, so that the user can easily grip the ball 1, pitch the ball and catch the ball. By volumes of the hollow parts, softness can be slightly adjusted, and softness quality is enhanced by using force of an air spring, so that when gripping the ball 1, the user can grip the ball 1 softly. A trough part based on a chamfer part 4 is formed on a boundary between the adjacent cuticle bodies 3, so that the user can easily grip the ball 1 by touching the trough parts. The cuticle body 3 may be formed of a cushion part having elasticity on the sphere 2 side and a cuticle part for covering a surface part side of the cushion part.SELECTED DRAWING: Figure 2
