Description
TECHNICAL FIELD
[0001] The present invention relates to a golf putter head, and
more particularly, to a golf putter head which is convertible into
a blade putter head, mallet putter head or a two ball putter head
depending on a pivoting angle of a pivoting tail portion.
BACKGROUND ART
[0002] Golf is a club and ball sport, in which competing players
(or golfers) uses clubs shaped like a stick to hit the ball into
holes on a golf course using the fewest number of strokes. The golf
course may include a large area of 660,000 to 1,000,000 m.sup.2
such as fields, hills and mountains. The golf course may be
classified into a seaside course which is located at the beach and
an inland course which is located inland.
[0003] In playing golf which men and women of all ages can enjoy,
one of methods for reducing the number of strokes is using a
suitable golf club, among others, a suitable putter.
[0004] There are many types of putters, but the putters may be
largely classified into a straight type called blade or anser style
putter; and a crescent type called mallet and two ball style
putter.
[0005] FIG. 1 is a perspective view of a blade putter head of the
aforementioned putters. The blade putter distributes the weight of
the putter head to the toe and heel of the head and makes the sweet
spot larger (sweet spot means the center point to which a golf ball
is hit from a head face, is designed to result in an ideal stroke
if the golf ball hits the sweet spot).
[0006] FIG. 2 is a perspective view of a mallet style putter head
of the aforementioned putters. The mallet style putter has the head
with larger width backwardly and is effective to create a visibly
stable address (which refers to a state where a player decides the
position of his/her feet to hit the golf ball and places the head
on the ground, and usually, means pointing the face close to the
golf ball). In the case of the mallet style putter, the moment of
inertia which is improved about 30 to 40% due to the center of
gravity shifted to the rear side of the head and the weight
distributed to the toe and heel compared to the blade putter makes
a larger sweet spot and provides stable putting stroke.
[0007] FIG. 3 is a perspective view of a two ball putter head of
the aforementioned putters. The two ball putter has a head in which
two circles are drawn so that the two circles are aligned in the
same plane with an actual golf ball, leading to simple address or
arrangement of a putting line (which means a line connecting the
golf ball and hole on the green) and contributing the success rate
of putting (performing stroke to hit the ball into a hole on the
green).
[0008] Among the putters which are classified largely into straight
and crescent types, the straight type putter is advantages for
golfers who have stable strokes and are good at directions. The
crescent type putter is advantages for novice golfers since it has
a long head and easy to aim at a golf ball and has a center of
gravity that is distant from the face (hitting surface of the
putter).
[0009] As advantageous putters vary by each golfer's ability,
putters should be unavoidably replaced in line with the improvement
of the golfing ability, increasing the costs for replacing the
putters.
[0010] Novice golfers cannot help but exercise putting by carrying
many types of putters to decide a suitable putter. Thus, the novice
golfers suffer difficulty to replace putters frequently during
exercise.
DISCLOSURE
Technical Problem
[0011] The present invention has been made to solve the problems
and it is an object of the present invention to provide a golf
putter head which is convertible into a blade, mallet and two ball
putter by varying the center of gravity of the head by rotating and
arranging a pivoting tail portion in three directions (horizontal,
vertical and diagonal direction with respect to a rear surface of
the head) by a structure for controlling the degree of
pivoting.
Technical Solution
[0012] In order to achieve the object of the present invention, a
golf putter head that strikes a golf ball using the front surface
of a head when putting, the golf putter head comprises a lower
guide formed so as to extend from a bottom of a rear surface of the
head; an upper guide formed so as to extend from the rear surface
of the head at a predetermined distance above the lower guide in
order to define a space portion; and a pivoting tail portion, one
end of which is inserted into the space portion and pivotably fixed
in the space portion by means of a fixing member, wherein a
structure for controlling the degree of pivoting is formed in order
to control the pivoting angle of the pivoting tail portion, the
weight balance of the head is variable according to the pivoting
angle of the pivoting tail portion, and the pivoting tail portion
is formed in the shape of a bar having a rounded edge at the end
thereof that is fixed by the fixing member.
[0013] The structure for controlling the degree of pivoting
comprises a recess 420 which is formed at an identical interval in
a circumference of the pivoting tail portion 260 which is rounded,
a groove 430 which is formed in a center of an internal lateral
surface of the space portion 230, an elastic member 280 which is
inserted into the groove 430 and a ball 270 which is fitted to the
groove 430 and closely adhered to the recess 420 by the elastic
member 280, wherein the ball 270 acts as a stopper when the
pivoting tail portion 260 pivots.
[0014] Three recesses 420 are formed so that the pivoting tail
portion 260 is pivotably arranged in three directions comprising
horizontal, vertical and diagonal directions with respect to the
rear surface of the head 210.
[0015] A weight-adding portion 410 is formed to give additional
load to the other end of the pivoting tail portion 260.
Advantageous Effect
[0016] As described above, a golf putter head according to the
present invention enables a user to selectively convert the putter
into a blade, mallet or two ball putter depending on a position of
a pivoting tail portion (i.e. horizontal, diagonal and vertical
directions with respect to the rear surface of the head) and has
the effect of using three types of putters with a single putter and
reduces the burden for replacing the putter.
[0017] Further, the golf putter head according to the present
invention reduces inconvenience of changing putters for exercising
putting to decide a suitable putter.

[0027] Hereinafter, a golf putter head according to an exemplary
embodiment of the present invention will be described with
reference to accompanying drawings.
[0028] FIG. 4 is an exploded perspective view of a golf putter head
according to an exemplary embodiment of the present invention.
[0029] As shown in FIG. 4, a golf putter head according to an
exemplary embodiment of the present invention that strikes a golf
ball using the front surface of the head 210 when putting, the golf
putter head comprising: a lower guide 220 formed so as to extend
from a bottom of a rear surface of the head 210; an upper guide 240
formed so as to extend from the rear surface of the head 210 at a
predetermined distance above the lower guide 220 in order to define
a space portion 230; and a pivoting tail portion 260, one end of
which is inserted into the space portion 230 and pivotably fixed in
the space portion 230 by means of a fixing member 250, wherein a
structure for controlling the degree of pivoting is formed in order
to control the pivoting angle of the pivoting tail portion 260, the
weight balance of the head 210 is variable according to the
pivoting angle of the pivoting tail portion 260.
[0030] As described above, the golf putter head according to the
present invention largely includes the upper and lower guides 240
and 220 which are formed in the rear surface of the head 210, and
the pivoting tail portion 260 whose pivoting angle is controlled by
the structure for controlling the degree of pivoting. The upper and
lower guides 240 and 220 and the pivoting tail portion 260 will be
described in more detail with reference to accompanying drawings (a
ball 270, an elastic member 280 and a hinge hole 290 shown in FIG.
4 will be described later).
[0031] FIG. 5 is a perspective view of a lower guide and an upper
guide of the golf putter head according to an exemplary embodiment
of the present invention.
[0032] As shown in FIG. 5, the lower guide 220 may be formed so as
to extend from a bottom of a rear surface of head 210. In
particular, the lower guide 220 is shaped like a flat panel and is
formed so as to extend from an edge of the bottom of the rear
surface of the head 210, and as a result a lower surface of the
head 210 and a lower surface of the lower guide 220 form a plane
but two hinge holes 290 are perforated in a center at a
predetermined distance to insert a fixing member 250 (which will be
described later) into the hinge holes 290.
[0033] The upper guide 240 is formed so as to extend from the rear
surface of the head 210 at a predetermined distance above the lower
guide 220 (above the lower guide 220 means a direction opposite to
a direction in which the lower guide 220 is placed in the surface)
in order to define a space portion 230 (refer to FIG. 4). The
height of the space portion 230 is a little bit higher than that of
the pivoting tail portion 260 (to be described later).
[0034] That is, as the space portion 230 is provided to accommodate
therein the pivoting tail portion 260 (to be described later), the
height of the space portion 230 is a little bit higher than that of
the pivoting tail portion 260 so that the pivoting tail portion 260
is easily inserted into and taken out from the space portion
230.
[0035] FIG. 6 is a sectional view of the pivoting tail portion 260
and the structure for controlling the degree of pivoting of the
golf putter head according to the present invention.
[0036] As shown in FIG. 6, the pivoting tail portion 260 has an one
end inserted into the space portion 230 (refer to FIG. 4) and
pivotably fixed in the space portion 230 by means of the fixing
member 250. The pivoting tail portion 260 is formed in the shape of
a bar having a rounded edge at the end thereof that is fixed by the
fixing member 250. In particular, the structure for controlling the
degree of pivoting is formed to control the pivoting angle of the
pivoting tail portion 260. The pivoting tail portion 260 will be
described in more detail and then the structure for controlling the
degree of pivoting according to an exemplary embodiment will be
described.
[0037] As described above, the pivoting tail portion 260 is formed
in the shape of a bar, one end of which is inserted into the space
portion 230 and pivotably fixed in the space portion 220 by the
fixing member 250. As the pivoting tail portion 260 is pivotable by
the fixing member 250, the weight balance of the head 210 (refer to
FIG. 4) varies by the pivoting angle (degree of pivoting) of the
pivoting tail portion 260.
[0038] A weight-adding portion 410 may be further formed in the
other end of the pivoting tail portion 260 to give additional load.
The weight-adding portion 410 may be formed integrally in the other
end of the pivoting tail portion 260 or detachably coupled to the
pivoting tail portion 260 as necessary.
[0039] The structure for controlling the degree of pivoting
includes a recess 420 which is formed at an identical interval in a
circumference of the pivoting tail portion 260 which is rounded, a
groove 430 which is formed in a center of an internal lateral
surface of the space portion 230, an elastic member 280 which is
inserted into the groove 430 and a ball 270 which is fitted to the
groove 430 and closely adhered to the recess 420 by the elastic
member 280. The ball 270 acts as a stopper when the pivoting tail
portion 260 pivots. In particular, three recesses 420 may be formed
so that the pivoting tail portion 260 is pivotably arranged in
three directions including horizontal, vertical and diagonal
directions with respect to the rear surface of the head 210.
[0040] Hereinafter, the recesses 420, the groove 430, the elastic
member 280 and the ball 270 which form the structure for
controlling the degree of pivoting will be described in more
detail.
[0041] The recesses 420 are formed at an identical interval in the
circumference of the pivoting tail portion 260 that is rounded. The
depth of the recesses 420 may be formed to be suitable for the size
of the ball 270 so that one-third of the ball 270 (which will be
described later) is inserted into the recesses 420. In particular,
the number of the recesses 420 may be three recesses so that the
pivoting tail portion 260 is pivotably arranged in three directions
including horizontal, vertical and diagonal directions with respect
to the rear surface of the head 210.
[0042] That is, when an axis A and an axis B which are
perpendicular to each other centering on the hinge hole 290 into
which the fixing member 250 is fixed are formed, the axes A and B
pass a lower point of the recesses 420a and 420c, and another
recess 420b is formed therebetween. As a result, three recesses
420a, 420b and 420c are formed in a circumference of the hinge hole
290.
[0043] The groove 430 is formed in the center of the internal
lateral surface of the space portion 230. The center of the
internal lateral surface means the center of the surface falling
under the rear surface of the head 210 among six surfaces forming
the space portion 230. The location of the groove 430 may be a
location in which an axis passing through a center of the groove
430 is perpendicular to an axis passing through the center of the
hinge hole 290 of the lower guide 220.
[0044] The elastic member 280 supplies an elastic force to the ball
270 (to be described later) and the ball 270 is selectively
inserted into the recesses 420 and acts as a kind of a stopper when
the pivoting tail portion 260 pivots. The elastic member 280 may
include a coil spring, but not limited thereto.
[0045] The ball 270 is fitted to the groove 430 and is selectively
adhered to the recesses 420 by the elastic member 280. As described
above, the ball 270 may include a steel ball which is highly
wear-resistant to act as a stopper.
[0046] FIG. 7 is a partial cutaway perspective view of the golf
putter head according to the present invention when the golf putter
head is used as a blade putter. FIG. 8 is a partial cutaway
perspective view of the golf putter head according to the present
invention when the golf putter head is used as a mallet putter.
FIG. 9 is a partial cutaway perspective view of the golf putter
head according to the present invention when the golf putter head
is used as a two ball putter.
[0047] The process of using the golf putter head according to the
present invention converted into a blade putter, mallet putter and
two ball putter will be described with reference to accompanying
drawings.
[0048] If a user desires to use the golf putter head according to
the present invention as a blade putter, he/she may locate the
pivoting tail portion 260 in a horizontal direction with respect to
the rear surface of the head 210 (i.e., fit and adhere the ball 270
pressed by the elastic member 280 to the first recess 420a) as
shown in FIG. 7. If a user desires to use the golf putter head
according to the present invention as a mallet putter, he/she may
locate the pivoting tail portion 260 in a diagonal direction with
respect to the rear surface of the head 210 (i.e., fit and adhere
the ball 270 pressed by the elastic member 280 to the second recess
420b) as shown in FIG. 8.
[0049] If a user desires to use the golf putter head according to
the present invention as a two ball putter, he/she may locate the
pivoting tail portion 260 in a vertical direction with respect to
the rear surface of the head 210 (i.e. fit and adhere the ball 270
pressed by the elastic member 280 to the third recess 420c) as
shown in FIG. 9.
[0050] As above, the golf putter head according to the present
invention enables a user to selectively convert and use the golf
putter head as blade, mallet and two ball putters and has the
effect for using a single putter as three types of putters to
thereby reduce the replacement cost for the putter and
inconvenience in replacing the putters during putting exercise to
decide a suitable putter.
[0051] Although a few exemplary embodiments have been shown and
described, it will be appreciated by those skilled in the art that
changes may be made in these exemplary embodiments without
departing from the principles and spirit of the invention, the
range of which is defined in the appended claims and their
equivalents.
