GOLF PUTTER HEAD WITH INCREASED DIMENSIONS AND INCREASED MOMENT OF
INERTIA
Abstract
A golf putter head includes a face member with a front surface
arranged for impacting a golf ball. A rear member extends in an
arcuate path of substantially 180 degrees from a heel end of the
face member to a toe end of the face member. First and second
struts extend from the rear member to the face member and converge
toward each other as they approach the face member. A third strut
extends from the rear member to the face member and lies between
the first and second struts. A V-shaped marking is provided on an
upper surface of the face member between the heel and toe ends
thereof. One leg of the V-shaped marking is aligned with the first
strut and the other leg of the V-shaped marking is aligned with the
second strut.

Description
BACKGROUND OF THE INVENTION
[0001] This invention relates generally to golf equipment and, in
particular, to a golf putter head with increased dimensions and
increased moment of inertia.
[0002] Recent developments in golf equipment have resulted in golf
putter heads with high moments of inertia. For example, U.S. Pat.
No. 5,482,281 to D. W. Anderson discloses a putter head sold under
the name DANSER. The Anderson putter head has heel and toe weights
mounted on a lower plate-like member. The heel and toe weights and
the lower plate-like member are preferably made of heavyweight
material such as bronze or steel. An upper shell-like member,
preferably made of lightweight material such as plastic or
aluminum, is secured to the lower plate-like material to enclose
the heel and toe weights. U.S. Pat. No. 5,842,935 to M. J. Nelson
discloses a putter head sold under the name NELLI. The Nelson
putter head has a horseshoe shaped body formed of high density
material such as steel with thickened heel and toe portions. The
horseshoe shaped body includes a cavity which receives an insert
formed of low density material such as polyurethane. The insert
preferably constitutes about 15% of the total weight of the putter
head while constituting more than 50% of the total volume of the
putter head.
SUMMARY OF THE INVENTION
[0003] The present invention provides a golf putter head including
a face member having a heel end, a toe end and front surface
arranged for impacting a golf ball. The golf putter head also
includes a rear member extending in an arcuate path from the heel
end to the toe end of the face member, and first and second struts
extending from the rear member to the face member and converging
toward each other as they approach the face member. A third strut
may also be provided in the golf putter head extending from the
rear member to the face member and lying between the first and
second struts. The first, second and third struts may be aligned to
define four triangularly shaped open spaces between the face member
and the rear member. The face member has an upper surface with a
generally V-shaped marking thereon between the heel and toe ends
thereof. The V-shaped marking has one leg aligned with the first
strut and another leg aligned with the second strut. Preferably,
the first-mentioned leg of the V-shaped marking is aligned with an
edge of the first strut, and the other leg of the V-shaped marking
is aligned with an edge of the second strut.
DESCRIPTION OF THE DRAWINGS
[0004] FIG. 1 is a perspective view of a golf putter head according
to the preferred embodiment of the present invention;
[0005] FIG. 2 is a top plan view of the golf putter head shown in
FIG. 1; and
[0006] FIG. 3 is a bottom view of the golf putter head shown in
FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0007] Referring to FIG. 1, a golf putter head 10 includes a face
member 12 and a rear member 14. The rear member 14 extends in an
arcuate path of substantially 180 degrees from a heel end 16 of the
face member 12 to a toe end 18 of the face member 12. The face
member 12 has a front surface 12a arranged for impacting a golf
ball, an upper surface 12b with a hole 13 formed therein for
receiving a shaft 20, a lower surface 12c located opposite the
upper surface 12b, and a back surface 12d located opposite the
front surface 12a. The rear member 14 has an upper surface 14a, an
inner surface 14b, an outer surface 14c and a lower surface 14d.
The upper and lower surfaces 14a, 14d of the rear member 14 are
located opposite each other, and the inner and outer surfaces 14b,
14c of the rear member 14 are located opposite each other.
[0008] The golf putter head 10 further includes a first strut 22, a
second strut 24 and a third strut 26. The first and second struts
22, 24 extend from the rear member 14 to the face member 12 and
converge toward each other as they approach the face member 12. A
generally V-shaped marking 28 is provided on the upper surface 12b
of the face member 12 between the heel and toe ends 16, 18. The
V-shaped marking 28 has one leg 30 thereof aligned with an edge 22a
of the first strut 22 and another leg 32 thereof aligned with an
edge 24a of the second strut 24. The third strut 26 also extends
from the rear member 14 to the face member 12 and lies between the
first and second struts 22, 24.
[0009] It will be understood that the putter head 10 is preferably
made of lightweight material such as aluminum or titanium so that
it will have increased dimensions. For example, the putter head 10
may have a width W of between 4.0 and 12.0 inches, preferably 9.0
inches, measured between the heel end 12a and the toe end 12b of
the face member 12. Also, the putter head 10 may have a depth D of
between 2.0 and 6.0 inches, preferably 4.5 inches, measured between
the front surface 12a of the face member 12 and the outer surface
14a of the rear member 14. These dimensions for the width W and
depth D provide the putter head 10 with an increased moment of
inertia.
[0010] The first, second and third struts 22, 24 and 26 are
connected to the back surface 12d of the face member 12 and to the
inner surface 14b of the rear member 14 and are arranged to define
four triangularly shaped open spaces 34, 36, 38 and 40 between the
face member 12 and the rear member 14. Open spaces 34 and 40 are of
identical size while open spaces 36 and 38 are of identical size.
The open spaces 34, 36, 38 and 40 allow the putter head 10 to have
the increased dimensions described above without exceeding a
desired weight of approximately 350 to 500 grams.
