    • A golf club head having an undercut is disclosed. The club head includes a body defining a striking face, a top line, a sole, a back, a heel, and a toe. The back contains a cavity that extends in a direction substantially perpendicular to the face. A recesses is provided within the cavity, with the recess extending away from the cavity and toward the sole. The recess causes more of the club head mass to be oriented towards the perimeter of the club head, and optionally also toward the back of the club head. This enlarges the club sweet spot and increases the moment of inertia, and facilitates imparting a desired flight path to a struck golf ball, producing a more forgiving club. The recess may have a varying depth and/or a varying draft angle. A rear wall of the recess may be provided with a cutout to further reposition mass toward the club head perimeter. An insert, such as a vibration dampening member, may be provided within the recess. The insert may contain secondary inserts, such as weight members, therein in strategic locations. The insert may completely fill the recess, or may fill only a portion thereof.
    • 公开了一种具有底切的高尔夫球杆头。 球杆头包括限定醒目面部,顶线,底部,后部,脚后跟和脚趾的主体。 背面包含沿基本垂直于面的方向延伸的空腔。 在空腔内设有一个凹槽,凹槽从空腔向底部延伸。 该凹槽导致更多的球杆头质量朝向球杆头的周边,并且还可选地还朝向球杆头的后部。 这增加了俱乐部的甜点,并增加了惯性矩,并且有助于给打击的高尔夫球赋予期望的飞行路线,从而产生更宽容的俱乐部。 凹部可以具有变化的深度和/或变化的拔模斜度。 凹部的后壁可以设置有切口,以进一步将质量朝向球杆头周边重新定位。 诸如减振构件的插入件可以设置在凹部内。 插入件可以在其中在战略位置中包含次级插入件,例如重量构件。 插入件可以完全填充凹部,或者可以仅填充其一部分。

    • 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 damping 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。
