Abstract
A golf club including support members is disclosed herein. In accordance with the presently disclosed technology, the golf club may include a frontal portion including a striking face and a partially non-metallic rear portion. The partially non-metallic rear portion may include a non-metallic crown portion at an upper portion of the golf club head. The non-metallic crown portion may include a plurality of support members extending from the non-metallic crown portion toward the sole. The plurality of support members may include a central support member being located near a central portion of the golf club head in a heel-to-toe orientation. The non-metallic crown portion and the plurality of support members may form a unibody structural component.
Claims20
A golf club comprised of a golf club head, a shaft having a shaft axis coupled to the golf club head at a first end of the shaft and a grip coupled to the shaft at a second end of the shaft, wherein the golf club head comprises:
- wherein an x-axis is defined as a horizontal axis tangent to a face center with a positive x direction towards a heel of the golf club head, a y-axis is a vertical axis orthogonal to the x-axis with a positive y direction towards a crown, and a z-axis being orthogonal to both the x-axis and the y-axis with a positive z direction extending forward;
- a frontal portion comprised of metal comprising a striking face having the face center located at a forward portion of the golf club head;
- and
- a partially non-metallic rear portion coupled to and located aft of the frontal portion, the partially non-metallic rear portion comprising:
- a non-metallic crown portion at an upper portion of the golf club head;
- and
- a sole on a bottom portion of the golf club head;
- wherein the non-metallic crown portion comprises a plurality of support members extending from the non-metallic crown portion toward the sole, the plurality of support members essentially perpendicular to the striking face, the plurality of support members comprising a central support member being located near a central portion of the golf club head in a heel-to-toe orientation, extending substantially in line, along the z-axis, with the face center, and wherein the non-metallic crown portion and the plurality of support members form a unibody structural component;
- wherein the golf club head has a moment of inertia about the y-axis (MOI-Y) passing through a center of gravity (CG) of the golf club head, the golf club head has a moment of inertia about the z-axis (MOI-Z) passing through the CG, and the golf club head has a moment of inertia about the x-axis (MOI-X) passing through the CG.
