    • A golf club head having a recess located in a top portion thereof is described and claimed. The recess is located between the heel and the toe and extends toward the sole. The recess may be in the top line of the club head. An insert may be placed within the recess. The insert has a density that is less than the density of the club head body, and the insert preferably is a light-weight insert. The insert may include one or more dampening materials. The recess removes material from the club head, which in turn may do one or more of the following: increase the overall size of the club head, expand the size of the club head sweet spot, lower the club head center of gravity, and/or produce a greater club head moment of inertia. Thus, the recess and insert produce a more forgiving and playable golf club. As an alternative to a recess, a thin protrusion may be provided at the top line of the club head and the insert provided with a corresponding groove to facilitate attachment.
    • 描述和要求保护具有位于其顶部的凹部的高尔夫球杆头。 凹部位于脚跟和脚趾之间,并朝鞋底延伸。 凹槽可以在球杆头的顶部。 插入件可以放置在凹部内。 插入物的密度小于球杆头体的密度,并且插入件优选地是轻质插入物。 插入件可以包括一个或多个阻尼材料。 凹槽从球杆头中移除材料,球杆头又可以进行以下一个或多个操作:增加球杆头的总体尺寸,扩大球杆头甜点的尺寸,降低球杆头重心和/ 或产生更大的球杆头转动惯量。 因此,凹槽和插入件产生更宽容和可播放的高尔夫球杆。 作为凹部的替代,可以在球杆头的顶线处设置薄突起,并且插入件设置有相应的凹槽以便于附接。
