GOLF CLUB HEAD WITH ADJUSTABLE TILT MECHANISM
Abstract
This invention relates to a golf club head with an adjustable
tilt mechanism which is designed to be mounted between a shaft and
a head. Simply speaking, the neck of the head forms a long
adjusting cavity and the shaft is held in the long adjusting cavity
of the head by the pivot but pin permitting left or right swing.
The shaft is further locked in the lock ring and clamped in place
by the tie land and tie slot carved on the head to retain the shaft
fast within the long adjusting hole of the head. This mechanism
permits an adequate adjustment of tilt angle (an angle of
elevation) of the face. At the case of a long flight of ball
striking, the face at a desirable tilt angle will render the ball a
low or high parabola along the flight course to fly over the
obstacle.

comprising a head, a hosel, a retaining ring, and a shaft, in which
the head has a vertically formed neck because of the varying size
number assigned to head, and the tilt angles formed between the
face and the neck differs, and the shaft has a handle on the top
end, in which the main characteristics are: the neck of the head
having a long conic adjustable hole with wide opening and narrow

Description
FIELD OF THE INVENTION
[0001] This invention concerns the adjustable tilt mechanism for
the golf club in which the adjustable tilt mechanism is designed to
mount between a shaft and a head, capable of changing the tilt
angle of the face, easy for the golf player to strike the club and
render the ball a flight a low or a high parabola to shun away the
obstacle.
BACKGROUND OF THE INVENTION
[0002] FIGS. 1 and 2 show the schematic diagrams of the prior art
of a golf club that is very popular in use containing a head 10 and
a vertically formed neck 11. The head has a variety of sizes and
the face 12 and the neck 11 are linked in different angle. The neck
11 has a cavity 13 to receive a hosel 15 and a shaft 14 which is
glued fast in the cavity 13. Besides the difference in sizes, the
shaft length and gravity, the angle formed between the face 12, and
the shaft 14 varies greatly too. Simply speaking, when the angle
formed between the face 12 and the shaft 14 is wide obtuse, the
ball will fly low parabola course. Each golf bag will at least
contains the iron clubs No. 1, 2, 3, 4, 5, 6, 7, 8, 9, P and 9,
total nine clubs and the wood clubs No. 1, 3 and 5, three wood
clubs in order to strike the ball to the green with least number of
strokes. In reality, in most case in 18 holes play, because of poor
control over the ball flight, the ball occasionally falls behind
the obstacle (big tree) which stands between the ball and the
green. Under this circumstance, the seasoned player would change
his stance and the iron club with a acute angle face, so the ball
being struck would fly a high parabola flight over the obstacle, or
he would change his stance and uses the large-number iron club with
small angle to strike the ball flying a low parabola to penetrate
through the obstacle. From the above statement, it is learned that
the angle form between the face 12 of the head 10 and the shaft 14
is a critical factor to make a ball a low parabola or high parabola
flight. The adjustable tilt mechanism is provided between the head
and the shaft, for the unskillful player, it is easy way to promote
his golf playing interest. This serves the purpose the inventor
wants to design this adjustable tilt mechanism.
SUMMARY OF THE INVENTION
[0003] Because all golf clubs are formed at a fixed angle between
the head and the shaft, it is extremely hard for the unskillful
golf player to pick the right club to hit the right parabola for
the ball. For this reason, the inventor, for long experience in
manufacturing golf club and wide observation, has begun to come up
this invention with many trials and errors. This invention designs
an inverted conical long hole in the neck; the lower end of the
shaft passes the retaining ring and the hosel and enters into the
long adjustable hole in the neck to be locked by the lock pin with
the neck. However the shaft is so permitted to swing to left or to
right as to change the angle (elevation angle) between the face and
the shaft but still held firmly by the retaining ring and
adjustable hole in the neck.

DETAILED DESCRIPTION OF THE INVENTION
[0013] This invention will be explained in great detail with the
aid of a plurality of embodiments as illustrated in the drawings
attached.
[0014] FIG. 3 shows a disassembly view of an adjustable tilt
mechanism of this invention wherein the adjustable tilt mechanism
comprises a head 20, a hosel 30, a retaining ring 40, and a shaft
50.
[0015] As shown in the prior art of golf club, the head 20 is
vertically formed with the neck 21. The head 20 is numbered in size
and each size has a specified tilt formed between the face 22 and
the neck 21. But in this invention, the neck 21 of the head 20
provides a long adjustable hole 23 which has a wide opening and
narrow bottom. The opening rim has a plurality of tie slots 24
distributed at a specific angle. A through lock hole 35 is drilled
at the lower part of the neck 21 to receive the lock pin 26 so as
to lock the shaft 50 in the long adjustable hole 23.
[0016] The hosel 30 has a longitudinal hollow 31 in which inner
diameter equals to the outer diameter of the shaft 50. The bottom
face of the hosel 30 is in the similar shape of the neck top 21 of
the head 20. Along the inner rim of the hosel 30, there are three
tie lands 32.
[0017] The retaining ring 40 has an inner thread 41.
[0018] The shaft 50, as similar to that in the prior art of golf
club, has a handle 51 and a lock hole 52 at the lower end and a
thread section 52 in the middle section of the shaft 50.
[0019] Please refer to FIGS. 4 and 6 which show the adjustable tilt
mechanism. First, the inner thread 41 of the retaining ring 40 is
fitted in the thread section 53 of the shaft 50. The opening 31 of
the hosel 30 will receive the shaft 50 section exposed under the
retaining ring 40. When the lower end of the shaft 50 enters into
the long adjustable hole 23 of the neck 21 of the head 20, the lock
pin 26 will pass the lock hole 23 on the neck 21 and the lock hole
52 of the shaft 50. At this moment, the shaft 50 is permitted to
swing to left or to right pivoted on the lock pin 26 within the
adjustable hole 23 of the neck 21 to change the tilt (elevation
angle) formed between the face 22 of the head 20 and the shaft
50.
[0020] Please refer to FIGS. 4 and 5; when the shaft 50 is swung to
left in the adjustable hole 23 of the neck 21, the elevation angle
formed between the face 22 of the head 20, and the shaft 60
decreases. When the hosel 30 is pressed downward to the neck 21 of
the head 20, the tie land 32 on the hosel opening 31 will be
inserted into the tie slot 24 of the adjustable hole 23 (as shown
in a closed position of FIG. 5), the shaft 50 along the retaining
ring 40 and thread section 52 will move downward to hold the shaft
50 constantly fixed at the left position in the adjustable hole
23.
[0021] As shown in FIGS. 6 and 7, if it is intended to increase the
elevation angle between the face 22 of the head 20 and the shaft
50, the threaded section 53 and the retaining ring 40 are moved
backward, so the hosel 30 will slide upward, and the tie land 32 of
the hesel 30 will leave the tie slot 24 in the adjustable hole 23,
so the lock pin 26 and the shaft 50 are free to swing to the right
side. When the hosel 30 is pressed downward to the neck top 21 of
the head 20, the tie land 32 of the hosel opening 31 enters into
the tie slot 24 in the adjustable hole 23 (as shown in the closed
position of FIG. 7), the retaining 40 and the threaded section 53
of the shaft 50 press on the adjustable hole 23 to hold the shaft
50 constantly fixed at the right position.
[0022] The above statement indicates that the adjustable tilt
mechanism of the golf club is easy to adjust the elevation angle
formed between the face of the head and the shaft which will render
the ball a low or high parabola flight as the player desires to
shun away the obstacle.
[0023] Many changes and modifications in the above disclosed
embodiment of the invention can, of course, be carried out without
departing from the scope thereof, such the shape of the long
adjustable hole the number of the tie land and tie slot as
desirable. Accordingly, to promote the progress in science and the
useful arts, the invention is disclosed and is intended to be
limited only by the scope of the appended claims.
