Putter-type golf club head with an insert
A method for manufacturing a golf club head with an insert having a face plate is disclosed herein. The insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The insert preferably has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is preferably disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs.
1. A golf club head comprising:
a club head body having a front face with a recess therein;
an insert disposed within the recess, the insert comprising a body with an exterior surface, an interior surface and a perimeter defining the thickness of the body, the insert having a thickness ranging from 0.188 inch to 0.200 inch, the exterior surface of the insert having an indented portion, the indented portion having a depth ranging from 0.020 inch to 0.075 inch, the insert composed of a polymer material;
a face plate attached to the indented portion of the exterior surface of the insert, the face plate having a thickness ranging from 0.020 inch to 0.075 inch and a height ranging from 0.30 inch to 0.80 inch, the face plate composed of a material having a density greater than the density of the polymer material, the face plate covering less than 90% of the exterior surface of the insert.
2. The golf club head according to claim 1 further comprising means for attaching the insert within the recess of the body.
3. The golf club head according to claim 2 wherein the attachment means is an epoxy adhesive applied to the interior surface of the insert.
4. The golf club head according to claim 1 wherein the polymer material is a selected from the group consisting of 4,4′-diphenylmethane diisocyanate-polyester thermoplastic polyurethanes and para-phenylene diisocyanate-polyether thermoplastic polyurethane.
5. The golf club head according to claim 1 wherein the face plate is composed of a metal selected from the group consisting of steel alloys, steel, titanium, titanium alloys, amorphous metals, aluminum, aluminum alloys, magnesium, magnesium alloys and bonze.
6. The golf club head according to claim 1 wherein the face plate is composed of a polymer material selected from the group consisting of polycarbonates, polyamides, polyesters, and ABS materials.
7. A putter club head comprising:
a club head body comprising a front face, a toe to one side of the front face and a heel to the other side of the hunt face, and a sole, the front face having a recess therein, the recess defined by a frontal recess wall and an edge wall substantially perpendicular to the frontal recess wall, the edge wall defining the depth and area of the recess;
an insert disposed within the recess, the insert comprising a body with an exterior surface, an interior surface and a perimeter defining the thickness of the body, the insert having a thickness ranging from 0.188 inch to 0.200 inch, the perimeter having a plurality of integral tabs extending therefrom that engage the edge wall of the club head body, each of the plurality of integral tabs spaced a predetermined distance from each other thereby defining openings between the integral tabs, the exterior surface of the insert having an indented portion, the indented portion having a depth ranging from 0.020 inch to 0.075 inch, the insert composed of a thermoplastic polyurethane material; and
a face plate attached to the indented portion of the exterior surface of the insert, the face plate composed of a stainless steel alloy, the face plate having a thickness ranging from 0.020 inch to 0.075 inch and a height ranging from 0.30 inch to 0.80 inch, the face plate covering less than 90% of the exterior surface of the insert.
8. The putter-type golf club head according to claim 7 wherein the thermoplastic polyurethane material is a selected from the group consisting of 4,4′-diphenylmethane diisocyanate-polyester thermoplastic polyurethanes and a para-phenylene diisocyanate-polyether thermoplastic polyurethane.
