摘要： To provide a bowling pin which exhibits a pin action of the bowling pin which is generated due to strong hitting of the ball with the bowling pin close to a pin action of a conventional bowling pin. An upper core 25 and a lower core 23 are set in a core material forming mold 21, a molten synthetic resin is injected into a cavity 27 through a gate 26 and is cooled and, thereafter, the upper and lower cores are removed thus forming by molding the core material 3 which includes an upper hollow portion 5a having an upper opening, a lower hollow portion 5b having a lower opening and a circumferential groove 4a which surrounds a largest diameter portion of the core material and, thereafter, a resilient strip 4 is formed by filling a synthetic resin softer than a synthetic resin for forming the core material into the circumferential groove, an upper cap is mounted on the upper hollow portion and a lower cap is mounted on the lower hollow portion, a projecting portion of the upper cap is inserted into a recessed portion of an upper mold thus forming an upper engaging portion, a pin of a lower mold is inserted into a recessed portion of the lower cap thus forming a lower engaging portion, the core material is vertically fixed to the inside of the cavity while maintaining a gap around the core material, and a molten resin is injected into the gap through a gate thus covering the upper and lower caps, the resilient strip and the core material with the skin portion.

摘要： The present invention provides a bowling pin which exhibits the excellent durability while satisfying conditions required on the bowling pin such as a weight and a dry sound which is generated at the time of hitting. A hollow portion which extends in the vertical direction is formed in a core material which constitutes a bowling pin. Upper and lower end portions of the hollow portion are opened, wherein one cap is fitted into an opening and another cap is fitted into a lower-side opening. The whole of the core material and the cap are almost covered with a surface skin portion and a portion of the core material where the surface skin portion is not provided is formed of two line portions and a dial portion. The surface skin portion is white, the line portions are red and the dial portion is black.
摘要翻译：本发明提供了一种保龄球，其在满足保龄球所需的条件下具有优异的耐久性，例如在打击时产生的重量和干燥声音。在垂直方向上延伸的中空部分形成为构成保龄球的芯材。中空部分的上端部和下端部被打开，其中一个帽装配到开口中，另一个帽装配到下侧开口中。核心材料和盖子的整体几乎覆盖有表皮部分，并且未设置表面皮肤部分的芯部材料的一部分由两个线部分和转盘部分形成。表皮部分是白色的，线部分是红色的，表盘部分是黑色的。
