The shock absorption device is opening at a face portion and a bottom portion to form a crown, a toe, a heel, and a neck of the golf club head. A weight device, which is made of a wear-resisting material with a specific weight greater than six, such as stainless, is fixed to the shock absorption device at the bottom portion to form a bottom of the golf club head. An elastic device, which is made of a material with an elasticity greater than the shock absorption device and the weight device, such as titanium alloy, fixed to the shock absorption device at the face portion to form a face of the golf club head.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates generally to a golf club, and more particularly to a golf club head with lower center of gravity and well shock absorption capacity.
  • 2. Description of the Related Art
  • U.S. Pat. No. 5,494,281 taught a golf club head including a head casing made of magnesium alloy and a face made of titanium alloy, aluminum alloy, or ceramics. The magnesium alloy has advantages of, compared to the titanium alloy, lighter in weight, well shock absorption capacity, and cheaper. For mass production, it may be made by die casting. The drawbacks are: a casing 90 made by die casting is thinker at a crown 91, a toe 92, a bottom 93, and a heel 94, as shown in FIG. 4 and FIG. 5). Such golf club head cannot be made with a greater size.
  • Taiwan Patent Publication No. 590028 disclosed a hollow golf club head divided into a front member and a rear member. The patent taught the rear member may be made of stainless, aluminum, magnesium or the alloy of those. The invention didn't teach how to divide the golf club head. The present inventor provided a solution and it had been filed as a patent in Taiwan (filing number 94128835).
  • These patents taught that magnesium alloy may be used for shock absorption, but lack of the disclosure of the requirement of weight distribution and wear-resisting capacity on the bottom of the golf club head. The easiest way is mounting weight plates on the bottom. There still are magnesium alloy exposed on the bottom, so that it is not optimal in structure and in process.
  • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide a golf club head with lower center of gravity and well shock absorption capacity in a simple and fast process.
  • According to the objective of the present invention, a golf club head comprises a shock absorption device, which is made of a light shock absorbing material with a specific weight less than two. The shock absorption device is opening at a face portion and a bottom portion to form a crown, a toe, a heel, and a neck of the golf club head. A weight device, which is made of a wear-resisting material with a specific weight greater than six, is fixed to the shock absorption device at the bottom portion to form a bottom of the golf club head. An elastic device, which is made of a material with an elasticity greater than the shock absorption device and the weight device, fixed to the shock absorption device at the face portion to form a face of the golf club head.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a sectional view of a first preferred embodiment of the present invention;
  • FIG. 2 is a sectional view along the 2-2 line of FIG. 1;
  • FIG. 3 is a sectional view of a second preferred embodiment of the present invention;
  • FIG. 4 is a sectional view of the conventional golf club head made by die casting along the vertical direction; and
  • FIG. 5 is a sectional view of the conventional golf club head made by die casting along the horizontal direction.
  • DETAILED DESCRIPTION OF THE INVENTION
  • As shown in FIGS. 1 to 2, the first preferred embodiment of the present invention provides a wood golf club head 10, which comprises:
  • A shock absorption device 20 is made of a light shock absorbing material with a specific weight less than 2. The shock absorption device 20 is made into a shape closing to a main of the golf club head 10, which is opening at a face portion and a bottom portion, to form a crown 21, a toe 22, a heel 23, and a neck 24. The shock absorption device 20 is made of magnesium alloy and is made by die casting to form a one-piece member. The neck portion may be made as an integration or made by an independent tube (not shown), which may be made of magnesium alloy or aluminum alloy, bonded to the shock absorption device 20.
  • A weight device 30, which is made of a wear-resisting material with a specific weight greater than 6, is fixed to the shock absorption device 20 at the bottom portion to form a bottom of the golf club head 10. The weight device 30 may be made of stainless, ductile iron, maraging steel, and other metals. The weight device 30 may be made by casting, stamping, and so forth. The weight device 30 is fixed on the bottom portion of the shock absorption device 20 by a fixing member, such as adhesive, screws 31, individually or collectively.
  • An elastic device 40, which is made of a material with an elasticity greater than the shock absorption device 20 and the weight device 30, is fixed to the shock absorption device 20 at the face portion to form a face of the golf club head 10. The elastic device 40 may be made of titanium alloy having a face plate 41 and an annular protrusion 42 on a back of the face plate 41. The protrusion 42 has a plug member 43 on a free end thereof The shock absorption device 20 and the weight device 30 are provided with a slot 25 and 32 to be engaged with the plug member 43 of the elastic device 40. Adhesive (not shown) is added between the plug member 43 and the slots 25 and 32.
  • In addition, the shock absorption device 20 and the weight device 30 may be provided with a slot 26 and a plug member 33 for engagement.
  • The advantages of the present invention are:
  • 1. The present invention may provide a golf club head with a very low center of gravity, because that the main of the golf club head is made of magnesium alloy with a low specific weight, and the bottom is made of the stainless with a high specific weight, and the face is made of titanium alloy with a specific weight between the magnesium alloy and the stainless.
  • 2. The present invention may provide a golf club head with a well shock absorption property, because that the main of the golf club head is made of the magnesium alloy, which provides a well shock absorbing capacity. When a golfer hits a ball by a golf club, the shock wave transfers from the face to the hand of the golfer via the main, the neck and the shaft. The shock wave may be absorbed by the shock absorption device easier.
  • 3. The face is made of titanium alloy, which provides a well elasticity property. The face works with the main made of the light material and the bottom made of heavy material to provide a well performance and contact feeling of hitting.
  • 4. The magnesium alloy shock absorption device, which is made by die casing, is suitable for mass production without any problem of thinker wall of the head. The weight devices are made independently, so that they are made by different way and with different logos thereon to fit the same shock absorption device. That makes the production faster.
  • As shown in FIG. 3, the second preferred embodiment of the present invention is an iron golf club head 50 including a shock absorption device 60 as a main, a weight device 50 as a bottom, and an elastic device 80 as a face. The shock absorption device 60 has a neck as integration and is made of magnesium alloy. The weight device 50 is made of stainless, and the elastic device 80 is made of titanium alloy.
