Abstract
A golf club head is provided having a body and a face, with a slot in a perimeter region of the body of the club head adjacent the face. The slot increases the flex of the hitting surface on impact with a golf ball, thereby increasing the speed with which the ball rebounds off the hitting face and increases the overall distance the ball is hit. The slot preferably moves the sweet spot of the hitting face a distance X from the face center of the hitting face. The slot may be partially or wholly filled with an insert.
Claims20
A golf club head, the club head comprising:
- a face having a geometric face center and an area of maximum coefficient of restitution, wherein the maximum coefficient of restitution is greater than about 0.8, wherein the face has at least two portions having different thicknesses;
- a hollow body having a toe portion, a heel portion, a sole portion, a hosel, a crown portion and a heel portion, the hollow body defining a perimeter region and an inner cavity, wherein a slot is formed in the sole portion and at least a portion of the slot forms an opening into the inner cavity of the hollow body;
- and
- an elastomeric material disposed in the slot, and at least partially filling the slot, wherein the elastomeric material extends into the inner cavity, and
- wherein the elastomeric material is held within the slot by at least one of an interference fit and an adhesive.
A golf club head, the club head comprising:
- a face having a geometric face center and an area of maximum coefficient of restitution, wherein the maximum coefficient of restitution is greater than about 0.8, wherein the face has at least two portions having different thicknesses;
- a hollow body having a toe portion, a heel portion, a sole portion, a hosel, a crown portion and a heel portion, the hollow body defining a perimeter region and an inner cavity, wherein a slot is formed in the sole portion and at least a portion of the slot forms an opening into the inner cavity of the hollow body, wherein a first portion of the body forms a side of the slot closer to the face than a second portion of the body forming a side of the slot opposite the first portion, wherein the first portion extends further into the inner cavity than the second portion to form a pathway to the inner cavity of the hollow body;
- and
- an elastomeric material disposed in the slot, and at least partially filling the slot, wherein the elastomeric material extends into the inner cavity, and
- wherein the elastomeric material is held within the slot by at least one of an interference fit and an adhesive.
A golf club head, the club head comprising:
- a face having a geometric face center and an area of maximum coefficient of restitution, wherein the face has at least two portions having different thicknesses;
- a hollow body having a toe portion, a heel portion, a sole portion, a hosel, a crown portion and a heel portion, the hollow body defining a perimeter region and an inner cavity, wherein a slot is formed in the sole portion and at least a portion of the slot forms an opening into the inner cavity of the hollow body;
- and
- an elastomeric insert disposed in the slot, and at least partially filling the slot, wherein the elastomeric insert has a protrusion, wherein the protrusion engages a wall of the slot so that the insert is kept within the slot through normal use of the golf club head,
- wherein the elastomeric insert is held within the slot by at least one of an interference fit and an adhesive,
- wherein the area of maximum coefficient of restitution is disposed within a zone on the face and the area of maximum coefficient of restitution is disposed less than 20 mm from the geometric face center, and wherein the maximum coefficient of restitution is at least about 0.81.
