摘要:
Putters include a putter body having a ball striking face member made of a material having a first hardness characteristic. A cavity is defined in the putter body behind the ball striking face member, and plural openings are defined in the ball striking face member extending rearward with respect to the ball striking face member and into the cavity. A polymeric material at least partially fills the openings and the cavity, wherein the polymeric material has a second hardness characteristic that is softer than the first hardness characteristic. The ball striking face member and the polymeric material exposed in at least some of the openings provide a ball striking surface of the putter. The ball striking surface may include grooves or scorelines to affect the launch angle, spin, and/or roll of the ball during a putt. Methods for making such putter devices also are described.

A golf club head with a club head body having an external surface with a heel portion, a toe portion, a crown portion, a sole portion, and a front opening is described. A face insert support structure is located at the front opening. The support structure includes a peripheral member and a rear support member. The rear support member has a front surface and a rear surface. A face insert is attached at the front opening and closes the front opening of the body. An undercut fill structure is attached to a portion of the rear surface of the rear support member.

A putter head has a putter body having a base member defining a ball striking face surface. The putter body further has a first arm extending away from the base member and a second arm extending away from the base member, and a central member extending away from the base member and positioned between the first arm and the second arm. A weight assembly is supported by the putter body. The weight assembly has a beam member having a first end, a second end and a central portion. The central portion is supported by the central member along a first plane, and the first end of the beam member is supported by the first arm along a second plane. The second plane is generally transverse to the first plane.
摘要:
A golf club head with a hardened striking face portion that improves durability and performance is disclosed. More specifically, the golf club head disclosed may have a martensitic striking face portion that may be at least about 1.3 times harder than the rear portion of the golf club head due to the martensitic crystalline structure of the striking face portion foamed by heating and quenching the striking face portion of the golf club head.

A golf club head with an improved face insert is disclosed herein. More specifically, the present invention discloses a golf club head wherein the face insert has a cavity near the top surface of the face insert that extends vertically downward towards the bottom surface of the face insert while terminating short of the bottom surface. The face insert having the cavity serves to remove unnecessary weight from the upper surface weight of the face insert; while the cavity that terminates short of the bottom surface yields a solid face insert near the bottom surface to preserve the structural integrity of the face insert where the golf club head impacts a golf ball. The cavity created within the face insert may be filled in with a lightweight material that helps further maintain the structural integrity of the entire face insert while still removing unnecessary weight from the face insert.

A golf club head that may increase the degree of freedom in design, a face of the golf club head, and a method of manufacturing the golf club head are provided. At least part of the golf club head includes an alloy, and the alloy includes Co and Fe in a total amount of 33 mass % to 65 mass %, Ni in an amount of 15 mass % to 35 mass %, Cr in an amount of 10 mass % to 25 mass %, Mo in an amount of 3 mass % to 12 mass %, at least one of Nb in an amount of 2 mass % or less and W in an amount of 5 mass % or less, and at least one of Mn in an amount of 2 mass % or less and Ti in an amount of 1 mass % or less.

A golf club that utilizes multiple materials to achieve improved performance is disclosed herein. More specifically, the present invention relates to a golf club that utilizes different materials to construct different portions of the iron type golf club head allowing weight to be removed from portions of the golf club head that doesn't require such weighting. The current invention utilizes a lightweight material to form a blade portion of the golf club head while utilizing a standard steel material to form the hosel portion of the golf club head to allow the malleability characteristics of a golf club head to be maintained. The weight saved from the lightweight material used to create the blade portion can then be used to create a sole insert that is made out of a dense and heavy material to improve the CG and MOI characteristics of the golf club head to dramatically improve the performance of the golf club head. The current invention's usage of the multiple materials allows the performance of the golf club head to be increased without sacrificing the feel characteristics of the golf club head.
摘要:
A composite golf club head with improved sound characteristics is disclosed herein. More specifically, the present invention relates to a golf club head that utilizes a unique composite type material having a low damping coefficient; creating more discretionary weight to optimize performance without comprising the sound of the golf club head. Depending on the amount of discretionary weight desired, the present invention could replace parts of the crown, the sole, the striking face, or even all three of the above referenced components with a low-damping composite material to improve the performance. The low-damping composite material used in accordance with the current invention may generally have a damping loss factor (η) of less than about 0.02.
