Abstract

A shim or badge is affixed to a golf cub body to produce a cap-back iron, giving the appearance of a hollow-body iron. In this way, the golf club can be manufactured with the performance benefits of a game improvement iron, while providing the appearance of a blade, player's iron, and/or a hollow-body iron. For example, by using a lightweight and rigid shim or badge to close a cavity opening and extend into the toe portion in the golf club body, the golf club head can provide increased stiffness in the topline, while lowering CG. Various shim or badge arrangements and materials can be used, and a filler material and/or damper can be included within the cavity to improve sound and feel, while minimizing loss in COR.

First claim

1 .- 25 . (canceled)

26 . A clubhead for an iron-type golf club, the clubhead comprising:
a body having a heel portion, a toe portion, a top-line portion, a rear portion, a face portion, and a sole portion, the sole portion extending rearwardly from a lower end of the face portion to a lower portion of the rear portion; and a badge formed separately from and attached to the body, wherein a toeward portion of the badge is attached to the toe portion of the body such that the badge defines a toewardmost surface of the clubhead, wherein the badge is made of a material that has a lower density than a material of the body, and wherein the body defines an upper toewardmost surface of the toe portion, between the toewardmost surface of the clubhead, defined by the badge, and the top-line portion, and defines a lower toewardmost surface of the toe portion, between the toewardmost surface of the clubhead, defined by the badge, and the sole portion.

27 . The clubhead of claim 26 , wherein the badge defines a rearwardmost surface of the clubhead, between a sole bar of the body and the top-line portion of the body.

28 . The clubhead of claim 27 , wherein the badge extends into the toe portion by wrapping from the toe portion to the rear portion to connect at least a portion of the rearwardmost surface of body, between the sole bar of the body and the top-line portion of the body, and the toewardmost surface of clubhead.

29 . The clubhead of claim 26 , wherein a surface area of a toe portion of the badge, as projected onto a toe plane, defined as a plane perpendicular to a strike face of the clubhead and perpendicular to a ground plane, when the clubhead is in a zero loft orientation on the ground plane, is greater than a surface area of the upper toewardmost surface of the toe portion, as projected onto the toe plane.

30 . The clubhead of claim 26 , wherein a surface area of a toe portion of the badge, as projected onto a toe plane, defined as a plane perpendicular to a strike face of the clubhead and perpendicular to a ground plane, when the clubhead is in a zero loft orientation on the ground plane, is greater than a surface area of the lower toewardmost surface of the toe portion, as projected onto the toe plane.

31 . The clubhead of claim 26 , wherein a surface area of a toe portion of the badge, as projected onto a toe plane, defined as a plane perpendicular to a strike face of the clubhead and perpendicular to a ground plane, when the clubhead is in a zero loft orientation on the ground plane, is at least 100 mm 2 .

32 . The clubhead of claim 27 , wherein a surface area of the rearwardmost surface of the clubhead, defined by the badge, as projected onto a rear plane, defined as a plane perpendicular to a toe plane of the clubhead and perpendicular to a ground plane, when the clubhead is in the ideal address position on the ground plane, is at least 1,400 mm 2 , and wherein the toe plane is defined as a plane perpendicular to a strike face of the clubhead and perpendicular to the ground plane, when the clubhead is in a zero loft orientation on the ground plane.

33 . The clubhead of claim 26 , wherein a sole bar of the body defines a rearward portion of the sole portion, an upper ledge of the body extends below the top-line portion, a lower ledge of the body extends above the sole bar, and the badge is attached to the upper ledge and the lower ledge.

34 . The clubhead of claim 26 , wherein the toe portion comprises a support with a toeward ledge and the badge is further attached to the toeward ledge.

35 . The clubhead of claim 34 , wherein the support comprises an upright wall with one or more relief sections, wherein a combined area of the relief sections is equal to at least 20% of a toeward-facing surface of the upright wall.

36 . The clubhead of claim 26 , wherein the badge is a variable thickness badge.

37 . The clubhead of claim 36 , wherein an inner surface of the badge is three-dimensional and protrudes into the opening in the cavity.

38 . The clubhead of claim 36 , wherein no portion of the badge directly contacts the face portion.

39 . A clubhead for an iron-type golf club, the clubhead comprising:
a body having a heel portion, a toe portion, a top-line portion, a rear portion, a face portion, a sole portion extending rearwardly from a lower end of the face portion to a lower portion of the rear portion; and a badge formed separately from and received at least in part by the body, wherein the badge is configured to extend into the toe portion in part forming an outermost surface of the toe portion when received by the body, wherein the outermost surface of the toe portion is defined by a toe view of the clubhead at zero-degrees loft and rotated 90-degrees counter-clockwise about a vertical axis tangent to a face plane and normal to a ground plane, wherein the badge at least in part forms an outermost surface of the rear portion when received by the body, wherein the outermost surface of the rear portion is defined by a rear view of the clubhead at zero-degrees loft and rotated 180-degrees about a vertical axis tangent to the face plane and normal to the ground plane, wherein the badge is formed of a lower density material than the body, and wherein the body in part forms the outermost surface of the toe portion above and below the badge.

40 . The clubhead of claim 39 , wherein the badge is configured to extend into the toe portion by wrapping from the toe portion onto the rear portion to connect at least a portion of the outermost surface of the toe portion and a portion of the outermost surface of the rear portion.

41 . The clubhead of claim 40 , wherein the badge wraps from the toe portion to the rear portion, and wherein an angle measured between the rearwardmost surface of body, between the sole bar of the body and the top-line portion of the body, and the toewardmost surface of clubhead is at least 40-degrees.

42 . The clubhead of claim 39 , wherein an entirety of the badge is located below the top-line portion when the club head is in a proper address position on a ground plane.

43 . The clubhead of claim 42 , wherein an outermost surface of the top-line portion is made of a metal.

44 . The clubhead of claim 39 , wherein, a forward-most portion of the badge, at the toe portion, extends forwardly of a forward-most portion of the badge, at the rear portion.

45 . The clubhead of claim 26 , wherein the badge is a variable thickness badge, an inner surface of the badge protrudes into the opening in the cavity, and no portion of the badge directly contacts the face portion.
