Abstract

Disclosed herein is an iron-type golf club head that includes a body, made of a first material having a first density The body has a sole portion that includes an internal shelf. The iron-type golf club head also comprises a weight located within the internal cavity and at least partially seated on the internal shelf. The iron-type golf club head further comprises a filler material located within the internal cavity. The internal cavity has an internal cavity volume ranging between 40 cc to 55 cc.

First claim

What is claimed is:

1. An iron-type golf club head, comprising:
a body, made of a body material having a body material density, wherein the body comprises:
a heel portion;
a toe portion;
a sole portion, comprising an internal shelf;
a top portion;
a front portion, comprising a face opening; and
a rear portion, comprising a rear wall extending from the sole portion to the top portion;

a strike plate made of a strike plate material different than the body material, welded to the body and covering the face opening, thereby creating a strike face having a geometric center;
a weight, made of a weight material having a weight density greater than the body material density, at least partially seated on the internal shelf and configured such that no portion of the weight defines an exterior surface of the golf club head, and the weight does not contact the strike face;
an internal cavity, having an internal cavity volume, defined by the sole portion, the top portion, the front portion, and the rear portion; and
an elastomer filler material, located within the internal cavity;
wherein:
the golf club head has an external club head volume ranging between 40 cc to 55 cc, and a ratio of the internal cavity volume to the external club head volume is at least 0.14 and the internal cavity volume is no more than 20 cc;
the top portion has a maximum topline width Wtopline that is 5.0-9.0 mm;
an offset, in a front-to-rear direction, between a forwardmost portion of a hosel and a leading edge of the strike face is less than 4.0 mm;
the golf club head has a blade length (LB);
the weight has a weight height (HW), a weight depth (DW), a weight length (LW) that is greater than the weight height (HW) and the weight depth (DW), and the weight length (LW) is at least 35% of the blade length (LB);
the weight density is at least 12 g/cc and the weight has a mass of at least 10 grams;
the internal cavity has a topline-adjacent cavity depth proximate the top portion that is no more than 6 mm;
a midplane is located halfway between a maximum toe height and a ground plane when the golf club head is in an address position, the internal cavity extends below the midplane and above the midplane, and above the midplane the internal cavity comprises:
an above midplane maximum front-to-back cavity depth that is no more than 13 mm; and
an above midplane minimum front-to-back cavity depth that is less than the above midplane maximum front-to-back cavity depth;

the elastomer filler material extends above the midplane and below the midplane; and
the strike plate further comprises a sole wrap portion that defines a part of the sole portion, and a portion of the sole wrap portion is welded to the sole portion at a location at least 4 mm rearward of a leading edge of the strike plate.

2. The iron-type golf club head of claim 1 , wherein the elastomer filler material contacts a portion of the sole wrap portion.

3. The iron-type golf club head of claim 2 , further including an injection port extending through the toe portion to the internal cavity, the internal shelf being located below an interior portion of the injection port, and a portion of the weight is at least 20 mm toeward of the geometric center of the strike face.

4. The iron-type golf club head of claim 3 , wherein a portion of a peripheral weld along a top perimeter of the strike plate is on the front portion and is below the top portion, and the elastomer filler material extends above the top perimeter of the strike plate.

5. The iron-type golf club head of claim 4 , wherein the weight length (LW) is less than 65% of the blade length (LB), the external club head volume is 45-55 cc, and the golf club head has a center of gravity located at a Z-up elevation of 17.9-20 mm above the ground plane.

6. The iron-type golf club head of claim 1 , wherein the ratio of the internal cavity volume to the external club head volume is no more than 0.385, the above midplane maximum front-to-back cavity depth is no more than 12 mm, the weight length (LW) is at least four times the weight depth (DW), the blade length (LB) is 73-83 mm, and the elastomer filler material comprises at least one of a silicone, a polyurethane, or a foam.

7. The iron-type golf club head of claim 6 , wherein a center of gravity of the weight is located toeward of the geometric center of the strike face.

8. The iron-type golf club head of claim 7 , wherein the weight length (LW) is less than 65% of the blade length (LB), a maximum weight height elevation (HWT) of the weight is less than a geometric center height (HGC) of the geometric center of the strike face, the offset is less than 3.5 mm, a portion of the sole wrap portion is welded to the sole portion at a location at least 4 mm rearward of a leading edge of the strike face, a sole wrap thickness Tsolewrap is a minimum thickness of the sole wrap portion defining a transition between the front portion and the sole portion, and a ratio of the sole wrap thickness Tsolewrap to a face maximum thickness Tfacemax is 0.40-1.0.

9. The iron-type golf club head of claim 8 , wherein a portion of a peripheral weld along a top perimeter of the strike plate is on the front portion and is below the top portion, the elastomer filler material extends above the top perimeter of the strike plate, and the elastomer filler material contacts a portion of the sole wrap portion.

10. The iron-type golf club head of claim 8 , wherein the external club head volume is 45-55 cc, a sole thickness Tsole is a minimum thickness of the sole wrap portion defining the sole portion, and the sole thickness Tsole is less than the sole wrap thickness Tsolewrap.

11.
