Three wing reinforced golf club head
Abstract
A novel golf club head for increasing the driving distance and
the accuracy of the flying direction of a golf ball includes a body
shell, a faceplate that is held on the body shell for striking the
golf ball, and internal elements mounted in the body shell for
reinforcing the faceplate. The thickness of the club face is
reduced by using titanium as a head material. Connection of the
sole and crown of the head with three wings of titanium
reinforcements as the inner head structure of this invention
reinforces a spring-like property to the face plate allowing the
ball to repel off the clubface faster, with a bouncining effect.
The loss of power is minimized and remained within the clubface.
The speed and flying distance of the golf ball impacted with the
head of this invention increased drastically. Accuracy of the
flying direction is thus increased.

Description
[0001] This invention relates to a golf club for increasing the
driving distance and the accuracy of the flying direction of a golf
ball.
[0002] 1. Field of the Invention
[0003] A golf club is invented for increasing the driving distance
and the accuracy of the flying direction. The titanium clubface and
the sole and crown of the head connected with three wings of
titanium reinforces a spring-like propertyminimizes the club
thickness requirement.
[0004] 2. Description of the Prior Art
[0005] Improving golf head for longer flying distance and accurate
impact has been described in many prior arts. U.S. Pat. No.
5,499,814 to Lu illustrates a reinforced head for a golf club
including a body shell, a face plate held on the body shell for
striking the golf ball and an internal element mounted in the body
shell. The reinforcing element 16 is mounted within the body shell
behind the faceplate. Use of a titanium alloy is suggested for the
reinforcing element 16. The reinforcing element 16 is comprised of
sophisticated backing members to the support plate. The faceplate
14 is anchored in position by a mechanical mounting of a
sophisticated design. The key concept of Lu's invention is that the
faceplate 14 is constructed to withstand the stress of impact with
a golf ball while providing for some limited deflection from the
static position to the striking position. However, it is clear that
energy will be lost when the faceplate 14 hits the support plate
30. Then the bouncing force will be lessened and the flying
distance of the golf ball will be decreased. The Lu's invention is
so sophisticated and complex that a commercialization is
difficult.
[0006] U.S. Pat. No. 5,380,010 to Werner, et al. illustrates a golf
club of hollow construction including a shell wall, which is
attached to the backside of the faceplates and extends rearward to
a mass mounted as part of the head. Their idea of the improvement
in strength and rigidity is shown in FIGS. 9 and 10. They insist
that bending stress is decreased by decreasing the distance of top
edge and bottom edge of the faceplate. They installed shell wall 20
inboard from the edge of the strike face at least 0.15 inch or at
least about 10% of the height of the strike face. But, no data of
increasing flying distance is illustrated.
[0007] U.S. Pat. No. 5,451,058 to Price, et al. illustrates a golf
club having a force transfer assembly formed internally in the golf
club head whereby the face plate is blended into the handle. They
installed force transfer assembly including many members connected
in any 3-dimensionally spaced configuration with respect to each
other. They insist that their club eliminates the "hot-spots" in
the face metal, which results in an inconsistent bending and
transmission of energy of the ball. Their golf club strikes the
golf ball with "L" type rod though it may significantly increase
the efficiency of transmission of energy by direct contact to the
rear of the head and the soleplate. Resilient bouncing force is
decreased, accordingly.
SUMMARY OF THE INVENTION
[0008] It is the purpose of this invention to provide a golf club
with increased driving distance and the accuracy of the flying
direction of a golf ball. The golf club head of this invention
includes a body shell, a faceplate that is held on the body shell
for striking the golf ball, and internal reinforcement elements
mounted in the body shell for reinforcing the faceplate. More
specifically, using titanium as a head material minimizes the
thickness of the clubface. The sole and crown of the head are
connected with three wings of titanium reinforcement as the inner
head structure to reinforce a spring-like property to the face
plate allowing the ball to bounce off the clubface faster. The loss
of power is minimized and remained within the clubface. The speed
and flying distance of the golf ball impacted with the head of this
invention increase drastically. Accuracy of the flying direction is
also enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIG. 1 to FIG. 5, it is easily understood that
the club head has hollow structure reinforced with three wings.
Nothing is introduced to fill the void in the head.
[0015] FIG. 1 is an aerial view of crown of the club head. When
viewed at this position, the wings are approximately 1 mm thick in
width. The wings are approximately 2 mm away from the face of the
club. The wings are positioned in the center of the toe and the
hosel.
[0016] Three wings shown in FIG. 1 as 11, 12 and 13 are installed
inside the head at the locations of 21, 22 and 23, respectively and
securely welded at the points of 31, 32, 33 and 34 in FIG. 1 and
35, 36, 37 and 38 in FIG. 2. Two wings of 11 and 12 have projected
length of 5.04 cm when look at the front view of FIG. 2. They are
positioned side by side in the center of the club as shown in from
FIG. 1 to FIG. 3.
[0017] FIG. 4 is a toe view of the club head. When viewed at this
position the wings 11 and 12 have an oval-shaped curve. The top of
the wings are approximately 1 cm wide and the bottom of the wings
approximately 0.5 cm wide. The thickness for the middle of the
wings shall vary because of the differentials of thickness for the
top and bottom of the beam.
[0018] The shape of the wings are curved so that the center of
gravity directs towards the back allowing the club head to release
the ball in the air in a better angle of trajectory. This allows
the ball easy to airbone carry more. Directing the gravity in the
back allows a better accuracy as well as an enhanced
consistency.
[0019] Without the wings, at impact, 25% of the power is distorted
throughout the sole and the crown of the head. By welding these
three wings to the sole and the crown of the head as shown above,
the velocity is quarantined within the face of the club.
[0020] Once the crown and sole are attached with the beam, the
power transfer would be strictly minimized towards the clubface,
allowing the ball to increase in both speed and distance, upon
impact. This produces a tighter spring impact of the golf ball.
[0021] Measured Coefficient of Restitution (COR), suggested by the
staff of USGA (United States Golf Association) in the Spring of
2000 Conforming Ball Booklet, records well over 0.83. Which means
that this golf head bounces the golf ball more than any other
previous golf head. Tests done by robotics and average golf players
with swing speed between 105 to 110 mile per hour shows the same
results of increased "Yardage" of at least 5%.
[0022] Therefore the ball speed as well as distance is improved.
The best of this invention is using Beta titanium as the raw
material of the head and wings and welding them by electricity.
