Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This is a Continuation-in-part application of Ser. No.
09/885,965, filed Jun. 22, 2001, entitled "Shock-Absorbing
Golf-Club Head".
[0003] This invention relates to a golf club head, particularly to
one provided with an angle-indicating device for a golfer to strike
a ball by adjusting the striking angle and action by checking the
point of the angle indicating marks pointed by a pointing member of
the device so as to stabilize striking a ball.
[0004] 2. Description of the Prior Arts
[0005] The number of people playing golf has been increasing as
this sport has been growing popular, and beginners always learn its
technique from experienced players about striking postures, angles
of the gold club to a ball, etc. incessantly making practice to
upgrade striking stability. In teaching techniques of playing golf,
a tutor may at first verbally explain various key points of correct
methods for striking, and learners have to actually hold a golf
club and strike a ball personally to gradually acquire better
tricks, spending not a few time to correct and adjust their own
postures and striking actions. The stabilized striking always
affects the flying direction of a ball, but it may be difficult to
maintain the same striking point of a ball and the striking angle
to a ball. The main reason of this drawback lies in the golf club
head not provided any indicating marks to let players to confirm
the striking point and the striking angle of a golf club head to a
ball, so beginners or not so experienced players cannot strike a
ball accurately.
SUMMARY OF THE INVENTION
[0006] The purpose of the invention is to offer a golf club head
provided with an angle indicating marks for a player to adjust the
striking angle of a gold club head to a ball for enhancing striking
stability.
[0007] The feature of the invention is an angle indicating device
provided in an upper portion of a club head to be easily seen by a
player, and the angle indication device includes an pointing member
rotatable with a gravity center positioned very low to point one of
plural indicating marks formed on an upper surface of the device.
Then a player can look at the pointing member and adjust its
position to one of the indicating marks for the correct angle of
the striking surface of the club head towards the ball.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] A preferred embodiment of a golf club head 1 in the present
invention, as shown in FIG. 1, includes a ferrule 11 at one side
for connecting a golf club 12, a striking surface formed in a front
side, and an angle indicating device 2 fixed in an upper surface
nearly parallel to the striking direction.
[0017] The angle indicating device 2 consists of a supporting case
21 almost U-shaped to have an interior hollow defined by two
lengthwise vertical walls, two opposite side walls, a closed bottom
and an open top side, and a plurality of angle indicting marks 211
shown by means of slender cut lines, letters, figures, etc.
Further, the angle indicating device 2 consists of a rotary shaft
22 positioned between the two lengthwise sides and a pointing
member 22 rotatably supported by the rotary shaft 22 to have its
center of gravity very near to the bottom to keep its top end
always pointing to the upper side, for example, shaped like a water
drop, a pointed cone, an inverted cone or a round shape. Its top
end is not necessarily pointed, but a preferably bright colored
obvious mark 231 to be easily seen. FIG. 2 shows the angle
indicating device 2 positioned in a golf club head 1, with the
pointing member 23 having its top pointing upward to one of the
indicating marks 211 on one of the two longwise walls of the
supporting case 21 because of its low center of gravity attracted
by the terrestrial gravitation. The angle indicating marks 211 can
not only made on the upper surface of either of the two lengthwise
walls of the supporter 21, but on any location on the upper surface
of the club head 1 near the pointing member 23.
[0018] In using, a golf player stands at a proper location for
striking a ball, with the striking surface of his/her club head
placed near a ball 3, taking measure by eyesight and adjusting the
bodily position to the best position and the best angle for
striking. In the process of measuring and adjusting, the player
looks at one of the indicating marks 211 pointed by the pointing
member 23, checking the angle between the striking surface 13 and
the contacting surface of the ball 3. For example, as shown in FIG.
3, when the top end 231 of the pointing member 23 points the center
one of the indicating angle marks 211, the striking surface 13 of
the club head 1 is vertical against the ball 3. This striking angle
may let a club head strike the ball 3 to a medium distance, so a
player makes practice with this angle and becomes familiar with
this striking technique and then proceeds to practice striking for
a long distance and a short distance.
[0019] Next, as shown in FIG. 4, in order to strike a ball to a
comparatively long distance, the striking point is to be a little
lower than the center of gravity of a ball 3. Then a player holds
the club to let the club head 1 with its striking surface 13 a
little raised up, with the pointing member 23 having its top end
pointing to one of the angle indicating marks 211 near the striking
surface 13 to let the striking point a little higher than the
center of gravity of the ball 3. Then the ball may fly high to a
comparatively long distance.
[0020] Next, as shown in FIG. 5, in order to strike a ball to a
comparatively short distance or on a down slope, the striking
surface 13 has to slope down, with the rotary shaft 22 functioning
as a pivot to let the pointing member 23 rotate. Then the top of
the indicating member 23 points to a rather far point of the
indicating marks 211 from the striking surface 13. Therefore, the
ball 3 may fly in a direction almost near the ground, reaching a
short distance from the striking point.
[0021] After a player finishes practice, all the golf clubs are
placed in a golf club bag 4 as shown in FIG. 6, with the club heads
1 located to extend out of the bag 4, with the grips (not shown in
the Figures) located downward in the bag 4. At this condition, the
pointing member 23 rotates with the rotary shaft 22 as a pivot, the
bottom of the pointing member 23 points to the angle indicating
marks 211 with its top still at the upper side pointing to the
bottom of the club head 1. Then the top of the pointing member 23
is hidden in the head 1, not to be contacted by fingers, safe and
convenient.
[0022] Utilizing the angle indication device 2 of the invention, a
golf player can look at the top of the pointing member 23 located
between the two walls of the supporting case 21 for controlling the
striking angle and the flying distance of a ball after struck. At
the same time, as the angle indicating device 2 has the angle
indicating marks 211, a player can look at the top of the pointing
member 23 and knows the location it points for speculating the
possible effect of striking. Then the player can be aware of the
distance a ball flies by looking at the location of the indicating
marks 211 pointed by the top of the pointing member 23 by long-term
practice and experience. This function of the club head is very
difficult to be achieved by conventional golf club heads, assisting
a player learn and obtain the hints of striking techniques in a
short term.
[0023] Another characteristic of the invention is that the top of
the pointing member 23 is brilliantly colored or painted with
fluorescent powder or the like, making the obvious mark 231. So a
player cannot fail to find out the angle indicating marks 211 the
top of the pointing member 23 points to, adding much convenience
for finding the best angle for striking a club head. Especially, a
maker can make the indicating marks very stark and obvious for a
player to depend on them for practicing. Maybe the angle indicating
marks can be made extremely clear for tall persons, as shown in
FIG. 7. In addition, the angle indication marks can be slender cut
lines, alphabets, characters, figures, or signs.
[0024] While the preferred embodiment has been described above, it
will be recognized and understood that various modifications may be
made therein and the appended claims are intended to cover all such
modifications that may fall within the spirit and scope of the
invention.
