Description
CROSS-REFERENCE
[0001] This application claims priority to and the benefit of Korea
Patent Application No. 20-2006-0028452, filed on Oct. 25, 2006, the
entire content of which is incorporated herein by reference.
BACKGROUND
[0002] 1. Field
[0003] The present utility model relates to a putter, and more
specifically, to a putter on the top surface of which are arranged
a plurality of mock-up golf balls whose centers are located to be
higher than the top surface of the body of putter to thereby allow
the mock-up golf balls to look like complete circles all the time
although either toe or heel of the putter is higher than the other,
thus allowing a golfer to take simpler and more correct aiming.
[0004] 2. Related Art
[0005] In a golf game, a golfer generally uses golf clubs such as
drivers, irons, and putters to put golf balls into hole cups. The
golfer scores points by making as few shots as possible.
[0006] The putter is one of most important clubs to put balls into
the hole clubs. The golfer shots a ball as pushing out to put the
ball into a hole club.
[0007] To put the ball into the hole cup correctly, the golfer's
skilled sense of movement and rhythm is required, but, most of all,
the directionality of the putter is needed. Therefore, the putter
should be manufactured to be capable of being easily aligned to the
hole cup and golf ball in a straight line.
[0008] The present inventor has proposed a putter registered as
Korean Utility Model Registration No. 20-0371299 on Dec. 17, 2004.
The above putter suggested by the present inventor has two mock-up
golf balls formed on the body thereof, wherein the mock-up golf
balls each have a half sphere shape cut with respect to its correct
center.
[0009] The above putter allowed any golfers to make a correct and
easy aiming because a golf ball to be shot and the two mock-up golf
balls arranged on the top surface of the putter could be aligned in
a straight line.
[0010] Notwithstanding, the conventional putter had problems as
followings.
[0011] The head and shaft of the putter are angled with each other
by a constant angle, and the shaft is angled with ground typically
by 60 to 80 degrees even though the angle is different with respect
to each golfer.
[0012] That is, most typically, the golfer shots the ball by swing
the club as a pendulum with the ball positioned on the ground which
meets the golfer's eyes with the perpendicular line.
[0013] The head of the putter should be correctly parallel with the
ground for the putting address.
[0014] However, most of amateurs take the various putting addresses
according to their height, body shape, putting custom, and so on,
which makes the toe or heel of the putter being lifting.
Accordingly the accuracy of shot can be lowered.
[0015] Especially, while the putter suggested by the present
inventor is designed so that the mock-up balls on the putter can be
aligned with the real ball in a straight line when the putter is
aimed, the putter still has an disadvantage in that the mock-up
balls can be seen as distorted eclipse to the golfer when the toe
or heel is lifted according to the golfer's putting address, which
can make it difficult of the golfer to make a correct aiming.
SUMMARY
[0016] Therefore, the present utility model has been designed to
solve the above problems.
[0017] It is an object of the present utility model to provide a
putter for golf which has a plurality of mock-up golf balls
arranged on the top surface thereof, wherein the centers of the
mock-up balls are positioned to be higher than the top surface of
the body so that the mock-up balls can be always seen as complete
circles to a golfer's eyes even though either toe or heel is lifted
up when the golfer makes an aiming.
[0018] To achieve the above object, a putter according to an
embodiment of the present utility model is provided, the putter
having an impacting surface on a front side thereof, a plurality of
mock-up golf balls arranged on a top surface thereof, and a shaft
fixed on a portion thereof, wherein the mock-up golf balls are
located on a virtual line extended longitudinally from a middle of
the impacting surface and the mock-up golf balls each are greater
than half a complete golf ball and smaller than the complete golf
ball.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] FIGS. 1 to 5 each are a prospective view, a front view, a
side view, a rear view and a plan view.
[0020] FIGS. 6 to 8 are views for illustrating an example using a
putter according to the present utility model.
DETAILED DESCRIPTION OF AN EMBODIMENTS
[0021] Hereinafter, the present utility model configured as above
will be described in more detail.
[0022] FIGS. 1 to 5 each are a prospective view, a front view, a
side view, a rear view and a plan view, and FIGS. 6 to 8 are views
for illustrating an example using a putter according to the present
utility model.
[0023] The centers of the mock-up golf balls 10, 11 refer to the
locations in which the balls 10, 11 each have the longest diameter
when the balls 10, 11 are cut out.
[0024] Referring to FIGS. 1 to 5, the putter 1 according to the
present utility model has an impacting surface 3 on its front
surface, a plurality of mock-up golf balls 10, 11 arranged on the
top surface 2 of its body, and a shaft connection hole 4 formed on
a portion of the top surface 2.
[0025] A shaft 100 for golf club is connected to the putter through
the shaft connection hole 4.
[0026] The mock-up golf balls 10, 11 each have a complete sphere
shape whose lower part is cut out horizontally, especially, at the
lower location than the centers of balls 10, 11.
[0027] The impacting surface 3 is formed so that its top surface is
lower than that of the mock-up balls 10, as shown in FIGS. 2 to
4.
[0028] In addition, a vertical line connecting between the centers
of the mock-up balls 10, 11 are perpendicular to the impacting
surface 3 as shown in FIG. 5.
[0029] A primary feature of the present utility model lies in the
form with which the mock-up balls 10, 11 are arranged, and this
will be described now in more detail with reference to FIG. 3.
[0030] The full height h0 of the putter 1 is a height equal to the
diameter of a ball having a perfect sphere shape, and the height h1
is a height of the impacting surface 3 on which a golf ball is
impacted and formed to be lower than the full height h0.
[0031] And, the height h2 from the bottom to the centers of the
mock-up balls 10, 11 is equal to half the full height h0.
[0032] The height h3 from the bottom to the top surface 2 of the
body is lower than the height h2 from the bottom to the centers of
the mock-up balls 10, 11.
[0033] That is, there should exist the height h4 from the top
surface 2 to the centers of the mock-up balls 10, 11.
[0034] Hereinafter, operations and effects of the present utility
model will be described with reference to FIGS. 6 to 8.
[0035] FIG. 6 shows a state aiming the putter 1 according to the
present utility model, in which the heights of the toe and heel are
parallel with the ground, which provides the most ideal case.
[0036] At this time, the shaft 100 of the putter 1 is angled with
the green by a constant angle (a).
[0037] That is, when a golfer looks down in the perpendicular
direction, the mock-up balls 10, 11 can be seen as complete
circles.
[0038] FIG. 7 shows a state in which the heel of the putter 1 is
lifted up.
[0039] At times, there can exist a case in which a golfer can not
take a correct putting address and thus can not help putting a ball
with the heel lifted up because of the golfer's wrong stance or
uneven green.
[0040] At this time, an angle (b) between the shaft 100 of the
putter 1 and green becomes greater than the angle (a) when the
perfect aiming is accomplished.
[0041] However, although the putter 1 is not kept to be parallel
and the heel is lifted up, even more correct aiming can be made and
thus much more putting can be achieved since the mock-up balls 10,
11 can be seen as complete circles to the golfer's eyes.
[0042] In other words, the mock-up balls 10, 11 each look like
having a completely circular contour because the mock-up balls 10,
11 are looked down in the perpendicular direction and the centers
of the mock-up balls 10, 11 are located upper than the top surface
2 of the body.
[0043] FIG. 8 shows a state in which the toe of the putter 1 is
lifted up.
[0044] At times, there can exist a case in which a golfer can not
take a correct putting address and thus can not help putting a ball
with the toe lifted up because of the golfer's wrong stance or
uneven green.
[0045] At this time, an angle (c) between the shaft 100 of the
putter 1 and green becomes smaller than the angle (a) when the
perfect aiming is accomplished.
[0046] However, although the putter 1 is not kept to be parallel
and the toe is lifted up, even more correct aiming can be made and
thus much more putting can be achieved since the mock-up balls 10,
11 can be seen as complete circles to the golfer's eyes.
[0047] In other words, as the example as described above in
reference to FIG. 7, the mock-up balls 10, 11 each look like having
a completely circular contour because the mock-up balls 10, 11 are
looked down in the perpendicular direction and the centers of the
mock-up balls 10, 11 are located upper than the top surface 2 of
the body.
[0048] Hereinafter, it will be described now how much deviation can
occur in angles (b) and (c) between the shaft 100 and green when
either toe or heel is lifted up due to the golfer's wrong
stance.
[0049] It has been known that the angle between the shaft 100 and
green generally ranges from 60 degrees to 80 degrees when a golfer
makes a putting stroke.
[0050] The angle (a) between the ground and shaft is called `lie
angle`, and the angles (b) and (c) (refer to FIGS. 7 and 8)
occurring due to the golfer's wrong stance are called `actual lay
angles`.
[0051] Accordingly, a putter is generally manufactured to have a
lie angle of 70 to 72 degrees based on the average of the actual
lie angles (b) and (c).
[0052] It can be seen that a putter having a lie angle of 70 to 72
degrees would have actual lie angles of 60 to 80 degrees when being
declined with the minimum angle by a golfer's stance.
[0053] And, the diameter of a golf ball should not be smaller than
42.67 mm in accordance to related regulations.
[0054] That is, it can be seen the diameter of a golf ball is
greater than 42.67 mm. As a consequence, the object of the present
utility model can be achieved if the mock-up balls 10, 11 each are
manufactured to be greater than 42.67 mm in the largest diameter
and the height from the bottom of the putter 1 to the centers of
the mock-up balls 10, 11 is greater than the height of the top
surface 2.
[0055] The putter according to the present utility model allows a
golfer to make an easy and swift aiming because the mock-up balls
can be always seen to be completely circular to the golfer's eyes
even though the putter is not parallel with green(ground) and makes
an inclination because of the toe or heel's being lifted up.
[0056] Although the specific preferred embodiment of the present
utility model is described with reference to the exemplary
drawings, the utility model is not limited to the embodiment and
drawings set forth herein, rather it is limited only to the
accompanying claims and many alternatives, modifications, and
variations will be apparent to those skilled in the art.
