Benefits of technology

[0015] The main objective of the invention is to provide a golf club head with an improved faceplate that will provide a large sweet spot and an increase in the COR of the faceplate so the golf club head can hit a golf ball a further distance.
[0016] The faceplate comprises an outside plate and an inside plate. The outside plate has a thickness of 1.0 to 2.0 millimeters and is made of high strength material. The inside plate has a thickness of 0.5 to 1.8 millimeters and is made of high strength material. The inside plate is hollow or is a mesh and is connected to the outside plate. Therefore, the outside plate provides strength and the inside plate provides flexibility to the faceplate. The COR of the faceplate will be improved, and the faceplate can be fabricated with a large area to increase sweet spot without reducing mechanical strength.

Problems solved by technology

Harsh shock, vibrations and sound caused by the impact cause a golfer's swing to be inconsistent.
However, a conventional faceplate is not particularly flexible and does not increase the size of sweet spot and the COR of the club face.
However, the stiffness and the toughness of the same material are inversely proportional material properties, which means the roughness decreases when the stiffness increases.
Therefore, conventional faceplates cannot simultaneously provide improved COR and high mechanical strength.
Even though a faceplate can be fabricated with a combination of flexible plate to improve COR and a rigid plate to provide strength to overcome the foresaid shortcoming, the combination of the two plates is too heavy for the club head.

Embodiment Construction

[0029] With reference to FIGS. 1 and 2, a golf club head (10) for a wood club in accordance with the present invention includes a body (11) and a faceplate (12). The body (11) can be made of high strength precipitation hardened (PH) stainless steel, titanium (Ti) alloy or other Fe-based high strength materials and has a top (not numbered), a bottom (not numbered), a hosel (110), a front face (111), a shank (112), a crown (113) and a sole (114). The crown (113) is formed on the top of the body (11). The sole (114) is formed on the bottom of the body (11). The shank (112) is formed on and extends from the top of the body (11). The hosel (110) is defined at the shank (112) to connect the golf club head (10) to a shaft (not shown). The front face (111) is formed on the body (11) between the crown (113) and the sole (114) and has a recess (115) in which the faceplate (12) is mounted.

[0030] With reference to FIGS. 2, 3a, 3b and 4, the faceplate (12) is held firmly in the recess (115) in ...

Abstract

A golf club head for a metal wood includes a body and a faceplate. The body has a front face having a recess. The faceplate is mounted in the recess and includes on outside plate and an inside faceplate. The outside plate has a thickness that is 1.0 to 2.0 millimeters and is made of high strength material. The inside plate has a thickness that is 0.5 to 1.8 millimeters and is made of high strength material. The inside plate, which is hollow or meshed, is connected to the outside plate. Therefore, the COR of the faceplate will be more consistent, and the faceplate can be fabricated with a large area.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a wood type golf club head, and more particularly to a wood type golf club head with a faceplate that has a high specific strength outside and inside platewelded together with empty spaces to increase the coefficient of restitution (COR) of the faceplate. [0003] 2. Description of Related Art [0004] The basic types of golf clubs are woods, irons and putters. Each type of club has a significantly different a head. To hit the ball powerfully and successfully, the head of the golf club is made of high strength material such as metal or composite materials. [0005] A wood golf club head generally has a crown, a sole, a face with a center of impact or “sweet spot”, etc. that are all well-known in this art. The sweet spot represents the spot of desired contact with the ball. [0006] Some basic tendencies in wood club head design follow. [0007] 1. Maximize volume of the club head. The volume o...
