Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to golf clubs and in
particular to golf putters having a unique weighting and alignment
system.
[0002] A wide variety of putter head designs have been developed in
order to aid a golfer in making more repetitive and consistent
strokes. A unique weighting and alignment system is illustrated in
U.S. Pat. No. 4,754,976 to Pelz which uses a plurality of golf
balls behind the striking face and a rear weight to stabilize the
putter during the execution of a putting stroke to hit a golf ball.
Other putters having weighting systems of interest are shown in
U.S. Pat. No. 5,580,058 to Coughlin that shows weights located
behind the heel and toe portions of the putter head. U.S. Pat. No.
5,997,409 to Matson shows a putter head with a pair of wing members
extending rearwardly. U.S. Pat. No. 5,993,324 to Gammil uses
longitudinal rods between front and rear faces of a putter head.
U.S. Pat. No. 6,270,422 to Fisher shows a putter head having
trailing weight members at the heel and toe portions. U.S.
Published Patent Application No. US2004/0132542 A1 to Olsavsky et
al. shows a putter head using a pair of cylindrical bars connected
between the rear face and a rear weight on the putter head on both
sides of a center reinforcing member.
[0003] It is well known that when green speeds are fast, a heavier
putter slows the golfer's hands allowing more control of the putter
head during the execution of a putting stroke. Conversely when
green speeds are slow, a lighter putter allows the hands to speed
up to hit a golf ball harder. Golfers often compensate for green
speeds by having at least two, and often more putters, that may be
selected for a particular green speed. The present invention
provides adjustability that allows the overall weight of the putter
to be adjusted in accordance with the speed of the greens on a
particular golf course so that the golfer is using the same
identical putter every time with only the overall weight being
adjusted. This promotes familiarity and confidence enabling a
golfer to execute putting strokes by relying on ingrained muscle
memory that is built up over many repeated uses of the same
putter.
[0004] The present invention is a golf putter head having a pair of
weighted cylindrical bar members extending rearwardly from the rear
face. The bar members are located in a direction perpendicular to
the ball striking face and parallel to the target line a golf ball
will traverse when hit on a putting surface. The bar members have
multiple features. Initially the bars provide weight at a location
behind and in close proximity to the ball striking area on the
clubface. Preferably the bars are located on opposite sides of the
center of percussion of the putter head, one being toward the toe
and the other being toward the heel of the putter head.
[0005] An important feature of the bar members is that the
preponderance of the weight is located at the rearmost area of the
bars. This increases the effective moment of inertia of the club
head providing more forgiveness when a golf ball is struck at a
location on the ball striking face other than the precise center of
percussion. To achieve this weight distribution, in a preferred
embodiment, the forward or proximal end attached to the club head
is hollow. The solid, heavier distal ends of the bar members are
rearward and spaced behind the ball striking face.
[0006] Preferably the club head body is made of a lightweight
material, such as aluminum, ceramic or the like and the bars are
made of heavier material such as steel, copper or tungsten. The
bars may be structured so that the bar weight is variable in order
to provide a precise weight to control the overall weight of the
putter head. This may be accomplished, as indicated above, by
making the weighted bars partially hollow in order to control the
exact amount of weight of the bar. In a preferred embodiment, the
forward end of each of the cylindrical bar members that is attached
to the rear face of the club head is threaded in order to cooperate
with threaded bores on the rear face. To assemble the cylindrical
bars to the putter head, they ate threaded into the bores in the
rear face and tightened with a suitable tool and permanently
secured therein with epoxy or suitable cement.
[0007] An additional intended feature of the invention is that the
cylindrical bar members may be removable and replaced by bars
having different weights to allow adjustment to a preferred swing
weight to coincide with the speed of the greens at a particular
golf course.
[0008] Still another important feature of the bar members is the
provision of an alignment tool for the golfer. Since the bar
members are located perpendicular to ball striking face of the
putter head in a front to rear direction, the bar members are
parallel to the target line and serve as an alignment device to aid
the golfer to aim the putter when the putter is in a normal address
position. In use, the golfer simply aligns the bars to aim the
putter head in the direction of the intended target line.
[0009] Another feature is the weight of the cylindrical bars
increases the effective polar moment of inertia. In addition, as
the putter head is swung, the weight configuration of the bat
members causes the putter head to continue on the path of the
accelerating force applied by the golfer. This results in keeping
the putter head more stable and moving on the same line toward the
target, particularly when the golf ball is not struck precisely on
the center of the ball striking face.
SUMMARY OF THE INVENTION
[0010] It is, therefore, an object of the present invention to
provide a putter head having a weight configuration that stabilizes
the putter head as it is swung to eliminate twisting and turning of
the club head during the execution of a putting stroke.
[0011] Another object of the present invention is the provision of
a putter head with weights that are adjustable to coincide with
particular green speeds.
[0012] Still another object of the present invention is the
provision of a putter head having a weight configuration that keeps
the putter head moving in a direction toward the intended target
line with a driving motion.
[0013] Another object of the present invention is the provision of
a putter head having a unique alignment design in the form of
cylindrical bars extending rearward from the dub head in a
direction parallel to the intended target line.
[0014] Other objects, advantages and salient features of the
invention will become apparent from the following detailed
description, which taken in conjunction with the annexed drawings,

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0029] The detailed embodiments of the present invention are
disclosed herein. It should be understood, however, that the
disclosed embodiments are merely exemplary of the invention, which
may be embodied in various forms. Therefore, the details disclosed
herein are not to be interpreted as limited, but merely as the
basis for the claims and as a basis for teaching one skilled in the
art how to make and/or use the invention.
[0030] Referring to the drawings, FIGS. 1 to 8 disclose a putter
head 100 of the present invention formed with a body portion 102
made of light weight material, such as aluminum, ceramic or the
like.
[0031] The putter head 100 includes a ball striking face 104, rear
face 106, top ridge 108, and bottom sole 110. The putter head 100
further includes a tear cavity formed by a heel mass 112, toe mass
114 and a lower flange 116. A detail of a shaft 118 is shown
connected on the top ridge 108 in a suitable sized bore (not
shown). It will be appreciated the shaft 118 may be of any suitable
length and conventionally would include a grip on the upper end
thereof.
[0032] Cylindrical bar members 120 are made of heavy metal such as
steel or tungsten. Proximal ends of the bar members 120 are
connected to and extend in a rearward direction from the rear face
106 of the putter head 100. The distal ends of the bar members 120
toward the rear of the putter head 100, have a preponderance of
weight in that area The cylindrical bat members 120 are disposed on
either side of the club head body 102 in a heel to toe direction,
in a location behind and on either side of the center area of
percussion on the ball striking face 104.
[0033] As shown in the sectional view of FIG. 8, the forward
proximal ends of the bar members 120 include a hollow cavity 122,
whereas the distal ends are solid. The depth of the hollow cavity
122 may be adjusted to vary the weight of the bar members 120. The
forward proximal ends of the bar members 120 are provided with
threads 124 that cooperate with threaded bores (not shown) in the
rear face 106 of the putter head 100 for connection thereto. The
distal ends of the bar members 120 include a tool slot 126 for
connection with a suitable tool, such as an Allen wrench, to
facilitate connection and removal of the bar members from the
putter head 100. The cylindrical bar members 120 may be permanently
attached by epoxy glue or may be removable should different
weighted bars be used.
[0034] The parallel cylindrical bar members 120 locate the center
of mass directly behind the striking face 104 and toward the rear
of the putter head 100. This weight distribution stabilizes the
hitting zone of the ball striking face 104. The weight of the
cylindrical bar members 120 creates a high moment of inertia
because of the remote location from the actual center of percussion
on the ball striking face 104 and also serves to drive the face 104
forward through the ball impact zone with a greater force and
momentum while minimizing twisting and turning of the putter head
100, particularly when miss-hits occur.
[0035] FIG. 9 shows the putter head 100 with one of the bar members
120 removed using an Allen wrench type tool that cooperates with
the tool slot 126.
[0036] FIG. 10 shows another embodiment of a putter type golf dub
head 200 that is similar to the embodiment described above. The
golf dub head 200 includes a wide lower flange 216 that extends
proximate the ends of cylindrical bar members 220 giving the putter
head an overall mallet type configuration. The top ridge 208
includes a bore 218 for connection of a shaft (not shown).
[0037] When green speeds are fast, a heavier putter slows the
golfer's hands allowing more control of the putter head during the
execution of a putting stroke. Conversely when green speeds are
slow, a lighter putter allows the hands to speed up to hit a golf
ball harder. The present invention provides adjustability that
allows the overall weight of the putter to be changed in accordance
with the speed of the greens on a particular golf course.
[0038] FIG. 11 shows another alternate embodiment of a putter head
300 with two cylindrical bar members 320 that are adjustable. The
bar members 320 are hollow along the longitudinal length thereof.
The proximal end of each of the bar members 320 is attached to the
rear face 306 with threads, as described with prior embodiments.
The distal end of the bar members 320 is provided with threads 322.
A cylindrical shaped weight member 324 is formed with threads 326
at the distal end thereof and is sized for insertion into the
hollow interior of a bar member 320 and connected thereto with the
cooperating threads 322 and 326. The weights 324, as shown in FIG.
11, are interchangeable. By adjusting the length of an individual
weight 324, the overall weight of a bar member 320 may be
adjusted.
[0039] FIGS. 12, 13 and 14 disclose additional embodiments of
putter heads in accordance with the present invention. It will be
appreciated that all the features describe hereinabove with respect
to the previous embodiments are equally applicable to these
additional embodiments. For example, the bar members may be weight
adjustable and formed in the same manner as described above.
[0040] FIG. 12 is a view of another embodiment of a golf putter
head 400 of the present invention. In this embodiment two
elongated, cylindrical bar members 420 are attached to a rear face
406 of a dub head body 402. The bar members diverge toward the heel
412 and toe 414 portions of the putter head 400 thus distributing
more weight toward the outer side areas.
[0041] FIG. 13 is a view of another embodiment of a golf putter
head 500 of the present invention. In this embodiment two
elongated, cylindrical bar members 520 are attached to a rear face
506 of a club head body 502. The bar members 520 converge toward
the center of the rear edge 516 of the putter head 500, thereby
distributing more weight toward the center and rear of the putter
head 500.
[0042] FIG. 14 is a view of another embodiment of a golf putter
head 600 of the present invention. In this embodiment a single
elongated, cylindrical bar member 620 is attached to a rear face
606 of a dub head body 602. The bar member 620 is perpendicular to
the putter head 600 and extends rearwardly from the rear face 606,
thus locating more weight directly behind the ball contact area of
the putter head 600.
[0043] FIG. 15 is a view of another embodiment of a golf putter
head 700 of the present invention. In this embodiment a plurality
of elongated, cylindrical bar members 720 are attached to a tear
face 706 of a dub head body 702. Each bar member 720 is located on
the rear face 706 and extends in a divergent angle relative to the
other bar members 720, thus forming a unique weight distribution
for the putter head 700.
[0044] While various preferred embodiments have been shown and
described, it will be understood that there is no intent to limit
the invention by such disclosure, but rather, is intended to cover
all modifications and alternate constructions falling within the
spirit and scope of the invention as defined in the appended
claims.
