Golf putter and system incorporating that putter
Abstract
A golf putter head includes a body having a ball-striking face
and an upper surface defined thereupon. First and second indicia
are defined upon the upper surface. The indicia lie in a line which
is generally perpendicular to the striking face. The first indicium
is closer to the striking face than is the second indicium, and the
indicia are spaced from one another and from the striking face so
that when a golf ball bearing an indicium having a size generally
similar to the size of the first indicium is disposed at a
preselected distance from the striking face, and with its indicium
uppermost, the first indicium will be equally spaced from the
second indicium and from the indicium on the golf ball.

Description
FIELD OF THE INVENTION
[0001] This invention relates generally to golf clubs. More
specifically, the invention relates to putters. Most specifically,
the invention relates to a golf putter used in combination with an
indicium-bearing golf ball to provide a pattern of indicia which
allow the golfer to readily control the trajectory of the putter
head.
BACKGROUND OF THE INVENTION
[0002] Putting is a very important part of the game of golf, and
many golfers find it very difficult to putt accurately. As a
consequence, a very large body of art has been developed relating
to putting and putters. Putters are often provided with markings,
guides and other devices which have the object of aiding a golfer
in directing a putter head along a desired trajectory. Some such
alignment devices are shown in U.S. Pat. Nos. 5,072,941; 5,308,068
and 3,333,854. The foregoing patents show alignment devices which
basically comprise a guide line projecting across a top face of the
head of the putter.
[0003] Another approach to providing for putter control and
alignment is represented by what is known as the "two ball" putter.
The basic concept of this putter is shown in U.S. Pat. No.
4,688,798. As described therein, the head of a golf putter includes
at least two simulated golf balls on an upper surface thereof.
These simulated golf balls are aligned with the preferred center of
percussion ("sweet spot") of the striking face of the putter. The
theory of operation of this system is that the player will visually
align the simulated golf balls with the ball being putted so as to
provide for accurate control of the trajectory of the putter head.
As disclosed therein, various simulations of golf balls, both
two-dimensional and three-dimensional, are employed in this design
of putter. Various embodiments of the two ball putter, including
three ball versions, have been implemented and are popular with a
number of golfers. Some such embodiments are shown in U.S. Pat.
Nos. 6,905,420; 6,793,588; 6,679,782; 6,506,125; and 6,471,600.
While such putters are relatively popular, a number of golfers find
that the relatively large simulated golf balls make the putters
difficult to use and/or compromise their accuracy.
[0004] As will be explained hereinbelow, the present invention
provides a putter head design which incorporates a uniquely
determined pattern of markings which, when used in combination with
an appropriately marked golf ball, provide for an alignment and
control system which greatly enhances the accuracy of a player's
putting. These and other advantages of the invention will be
apparent from the drawings, discussion and description which
follow.
BRIEF DESCRIPTION OF THE INVENTION
[0005] Disclosed herein is a head for a golf putter. The head
includes a body, a ball-striking face defined on the body, and an
upper surface defined on the body. First and second indicia are
defined on the upper surface. The indicia lie in a line which is
generally perpendicular to the striking face of the putter. The
first indicium is closer to the striking face than is the second
indicium. The indicia are spaced from one another and from the
striking face in a specific arrangement so that when a golf ball
bearing an indicium having a size generally similar to the size of
the first indicium is disposed at a preselected distance in the
range of 0-0.75 inches from the striking face, and with its
indicium uppermost, the first indicium will be spaced from the
second indicium and from the indicium on the golf ball by an equal
distance.
[0006] In particular instances, all of the indicia have a diameter
which is less than the 1.68 inch diameter of a standard golf ball,
and in specific instances, the indicia all have a diameter in the
range of 0.1-0.8 inch. In particular instances, the first and
second indicia have a generally similar size, and the indicium on
the golf ball used in conjunction with the putter will also have a
similar size. In specific instances, the indicia are circular. In
yet other instances, the putter head may include more than two of
such indicia.
[0007] The spacing between the centers of the first and second
indicia may be defined by a formula D.sub.1,2=D.sub.1,f+X+0.84
inches wherein D.sub.1,2 is the spacing, in inches, between the
first and second indicia; D.sub.1,f is the spacing in inches
between the center of the first indicium and a plane extending
perpendicular to the ball-striking face of the putter head, X is a
number having a value in the range of 0-0.75 inches and 0.84 inches
is the radius of a typical golf ball. In a particular instance, X
will have a value in the range of 0.2-0.6 inches.
[0008] Also disclosed herein is an aiming system for a golf putter.
The system includes the putter head described above as well as a
golf ball having a corresponding indicium defined thereupon.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is a perspective view of the golf putter system of
the present invention;
[0010] FIG. 2 is a perspective view of the golf putter head of the
present invention;
[0011] FIG. 3 is a top plan view of the system of the present
invention illustrating the geometric relation of the indicia
thereupon; and
[0012] FIGS. 4A-4C are schematic depictions of other embodiments of
golf putter systems of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0013] The present invention provides an aiming system for a golf
putter which allows a golfer to control the trajectory of the
putter head with a high degree of accuracy. Furthermore, the user
can intuitively adapt to the system, hence no long training is
required for its use. In addition, the system is relatively compact
and unobtrusive and may be readily incorporated into variously
configured putters.
[0014] Referring now to FIG. 1, there is shown a perspective view
of the system of the present invention in operation. The system
includes a golf putter having a putter head 10 structured in accord
with the principles of the present invention. The putter is used in
combination with a golf ball 12 marked with an indicium 14. As will
be seen from the figure, the putter head 10 also includes
corresponding indicia 16 and 18. The geometry of the putter head
and the placement of the indicia 16, 18 are selected so that in the
use of the putter the indicia 16, 18 on the putter will align with
the indicium 14 on the ball 12. Furthermore, the centers of all of
the indicia 14, 16, 18 will be equally spaced when the ball 14 is
proximate the striking face of the putter. This geometric
arrangement allows a golfer to readily track the trajectory of the
putter head 10 and accurately control it so as to strike the ball
12 with the sweet spot of the putter and putt the ball 12 along a
desired path of travel. It should be noted that in the use of the
system of the present invention, a golfer's eyes will be spaced
from the indicia by at least several feet; owing to the inherent
limits on the resolution of a typical user's eyes, some variation
in spacing of the indicia may be present without detracting from
the indicia appearing to be "equally spaced." Therefore, in the
context of this disclosure "equally spaced" indicia are understood
to include indicia which, while not precisely equally spaced,
appears to be equally spaced in the normal use of the putter.
[0015] Referring now to FIG. 2, there is shown a perspective view
of the putter head 10 of FIG. 1. It will be noted that no shaft is
included in the FIG. 2 drawing, and it is to be understood that
putters in accord with the present invention may incorporate shafts
of any design. Furthermore, shaft placement on the head may be
varied according to club design and user preference.
[0016] The putter head 10 of FIG. 2 comprises a body portion having
a ball-striking face 20 on the body. As is known in the art, this
face 20 may be grooved, embossed, or otherwise textured.
Furthermore, it may include inserts or other features, all as known
in the art. The putter head 10 of FIG. 2 includes an upper surface
22 which joins the striking face 20 in an angled relationship. As
will be further noted from FIG. 2, the upper surface 22 includes a
projecting portion 22' extending therefrom. Disposed upon this
projecting portion 22' are first, 16 and second, 18 indicia as
described above. The first indicium 16 is disposed closest to the
striking face 20 and the second 18 is farther from the striking
face 20. It should be noted that in some instances, the size of the
upper surface 22 may be sufficiently large so that the projecting
portion 22' may be eliminated, and all of the indicia incorporated
within the bulk of the upper surface. As will be seen, the indicia
16, 18 are aligned along a line which is generally perpendicular to
the striking face. In most instances, this alignment line will also
pass through a line extending vertically from the percussive center
(sweet spot) of the striking face 20.
[0017] Referring now to FIG. 3, there is shown a top plan view of a
golf putter head 10, generally similar to that described with
reference to FIGS. 1 and 2. Also shown is a golf ball 12. The
putter head 10 and golf ball 12 are depicted as they would be when
a player using the system of the present invention would be lining
up a putt. Accordingly, as shown, the golf ball 12 will be spaced
from the striking face 20 of the putter head 10 by a distance X
which will usually range from 0 to approximately 0.75 inches.
Typically, the ball 12 and striking face 20 will be spaced by a
distance of approximately 0.2-0.6 inches when the putt is being
lined up, and most typically, spacing will be approximately 0.5
inch. According to the principles of the present invention, the
second indicium 18 is spaced from the first indicium 16, which in
turn is spaced from a plane defined by the striking face 20 of the
club by a distance such that when the ball 12 is placed with its
indicium 14 uppermost and the ball 12 and putter head 20 are
positioned so as to align the putt, all three indicia 14, 16, 18
are linearly aligned, and the spacing between the first and second
indicia on the club, and the first indicium 16 and the indicium 14
on the ball are equal, as noted above.
[0018] The foregoing geometric relationship of the present
invention may, in particular embodiments, be established by the
formula: D.sub.1,2=D.sub.1,f+X+0.84 inches. As shown in FIG. 3,
D.sub.1,2 equals the distance, in inches, between the centers of
the first and second indicia 16, 18; the distance D.sub.1,f is the
distance in inches between the center of the first indicium 16 and
a plane defined by the striking face 20. As discussed above, X is
the spacing, in inches, between the ball 12 and the striking face
20, and as such will be in the range of 0-0.75 inches, and in
particular embodiments 0.2-0.6 inches, and in one specific
embodiment 0.5 inches. The factor 0.84 inches is the radius of a
typical golf ball. In a typical putter of the present invention,
the first 16 and second 18 indicia are spaced apart by at least
0.84 inches, and in specific instances the spacing is less than
1.68 inches, and typically in the range of 1-1.5 inches.
[0019] It has been found that indicia aligned according to the
foregoing geometries provide visual feedback to a golfer which
allows for the putter and ball to be readily aligned so as to
define a sight line which allows for accurate aiming of the putt.
Furthermore, the relative position of the indicia guides the golfer
when he or she is swinging the putter so as to provide a dynamic
feedback which allows for accurate control of the putter head
trajectory.
[0020] The putter of the present invention is differentiated from
prior art designs such as the two or three ball putter by the fact
that the indicia utilized are significantly smaller than the
diameter of a golf ball, and a unique spacing pattern is
incorporated which, when used with an appropriately marked ball,
provides a novel aiming system. In general, the diameter of the
indicia will be less than 1.68 inches, and more preferably will be
less than 1.0 inch. In particular, the indicia will have a diameter
in the range of 0.10-0.80 inch. As depicted, the indicia are shown
as dark-colored spots; however, such is not required by the present
invention. In some instances, at least one of the indicia may be
brightly colored, patterned, reflective, or otherwise structured so
as to increase its visibility. In particular instances, the indicia
may be made from a fluorescent material.
[0021] While the foregoing description has primarily been directed
to a system utilizing two circular indicia on the putter head and a
circular indicium on the golf ball, the present invention is not so
limited. In that regard, FIGS. 4A-4C show some further embodiments
of the present invention.
[0022] Referring now to FIG. 4A, there is shown a putter head 30
having three indicia 16, 18, 32 thereupon. As shown, the third
indicium 32 is linearly aligned with the first and second indicia
16, 18. Also as shown, the third indicium 32 is spaced from the
second 18 by a distance equal to the spacing between the second 18
and the first 16. However, such is not required by the present
invention. The third indicium 32 may be placed at a greater or
lesser distance. Also, it is to be understood that still other
indicia may be included.
[0023] Referring now to FIG. 4B, there is shown a putter head 40
generally similar to those previously described. However, the
indicia 42, 44 thereupon are triangularly shaped. In the context of
this disclosure, reference is made to the diameter of the indicia.
In the instance of noncircular indicia such as 42 and 44, the
diameter is understood to be the diameter of a circle circumscribed
about the indicium. As is seen in FIG. 4B, the golf ball 12 has a
corresponding triangular indicium 46 thereupon; however, it is to
be understood that the indicium on the golf ball 12 may be
otherwise configured. For example, it may be a circular indicium.
Also, the present invention may be practiced utilizing differently
configured indicia on the putter head. Therefore, it is to be
understood that the present invention may be practiced using
various combinations of identical or differing indicia.
[0024] Referring now to FIG. 4C, there is shown yet another putter
head 50 structured in accord with the principles of the present
invention. As illustrated, this head 50 is a rather large,
delta-shaped head having several openings defined therein to
provide for an appropriate distribution of the center of mass. This
head 50 is representative of one design of golf putter head
presently employed, and it is to be understood that yet other
designs may be structured to include the present invention. As
shown in FIG. 4C, the head 50 bears indicia 52, 54 which are
generally cross-shaped, and in this instance, the ball 12 also
bears a cross-shaped indicium 56. As will be apparent,
alternatively configured indicia may be utilized in the present
invention. While the golf ball used in the system of the present
invention has been described as having an indicium thereupon, it is
to be understood that the golf ball may include a number of indicia
thereupon. The only requirement in the use of the system is that an
indicium on the golf ball be disposed at an approximately topmost
point thereupon.
[0025] In accord with another aspect of the present invention, one
or more of the indicia on the putter may be made to be movable
relative to the others. This feature will allow a golfer to adjust
the spacing of the indicia to accommodate personal preferences. For
example, a golfer who chooses to line up a putt with the ball more
than the typical 0.5 inch spacing from the club face favored by
most golfers could increase the spacing between the first and
second indicia. Likewise, a golfer who favors having the ball
closer than 0.5 inches from the club face when lining up a putt
could decrease the spacing between the indicia. Adjustment of the
spacing between the indicia may be accomplished by having various
of the indicia mounted on a slidable member, or by the use of
repositionable adhesive markers.
[0026] From the foregoing, it will be understood that a golf putter
system of the present invention includes a pattern of appropriately
disposed indicia which cooperate with an indicium disposed on a
golf ball to allow a golfer to accurately align a putt and control
the putter head trajectory. The unique geometry of the system of
the present invention may be incorporated into various embodiments
and may be adapted to various putter head designs. Also, it is to
be understood that while this invention has primarily been
described with reference to golf putter heads, embodiments of this
invention may likewise be adapted to other golf clubs such as
drivers and irons.
[0027] In view of the foregoing, numerous modifications and
variations of the invention will be apparent to those of skill in
the art. The foregoing drawings, discussion and description are
illustrative of specific embodiments of the invention, but they are
not meant to be interpreted as limitations upon the practice
thereof. It is the following claims, including all equivalents,
which define the scope of the invention.
