Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to the golf game art and more
particularly to an improved golf club putter.
[0003] 2. Description of the Prior Art
[0004] In the sporting game of golf one of the types of strokes
requiring great hand to eye coordination and concentration while
making the stroke is the putting stroke. Many, many putters have
heretofore been utilized in an attempt to increase the accuracy of
the putting of the golf ball. However, there has not hereto fore
been a putter that allows for greater concentration and accuracy of
the putting stroke while still being an allowable golf club.
SUMMARY OF THE INVENTION
[0005] The golf club putter head of the present invention is
designed to provide a more accurate golf putting stroke. This is
achieved, according to a preferred embodiment thereof by placing
certain markings on the top of the putter head and having the
markings in a particular relationship to the putter face used to
strike the golf ball. The markings on the top of the putter may
include the representation of a half circle, which may be larger or
smaller than the diameter of the golf ball and a full circle spaced
toward the rear of the putter head from the half circle and which
may be larger or smaller than the diameter of a golf ball. A first
line may be marked on the top of the putter head along the top edge
of the putting face and along the diameter of the half circle
marking. A second line may be marked on the top of the putter head
perpendicular to the first line and along a diameter of the full
circle marking and bisecting the first line. The intersection of
the first line and the second line may be centered above the "sweet
spot" of the putting face. The first and second lines are in the
form of a "T".
[0006] In use, the alignment of the half and full circle markings
and the first and second lines allow the eyes of the person using
the putter to stroke the golf ball at the sweet spot for a mor
accurate putting stroke.
BRIEF DESCRIPTION OF THE DRAWING
[0007] The above and other objects of the present invention my be
more fully understood from the following detailed description taken
together with the accompanying drawing wherein similar reference
characters refer to similar elements throughout and in which:
[0008] FIGS. 1 to 4 illustrate a preferred embodiment of the
present invention;
[0009] FIG. 5 is a partial sectional view thereof;
[0010] FIGS. 6, 7 and 8 illustrate the use of the golf club putter
in striking a golf ball.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0011] Referring now to the drawing, there is illustrated in FIGS.
1 to 4 a preferred embodiment of a golf club putter head 1
according to the principles of the present invention. As shown
thereon, the golf club putter head 1 has a striking face 2 which is
the face utilized to strike a golf ball as described below and a
top face 1a. The golf club putter head 1 has a rounded portion 7 at
the rear thereof and has the side curved surfaces 6. The bottom
surface of the golf club putter head 1 is generally flat as shown
in FIG. 3. The golf club putter head 1 may have a rosin face insert
3 upon which may be marked the "sweet spot" 12. A shaft hold fast 5
is provided to which a golf club shaft 9 not shown) may be
attached.
[0012] A plurality of preselected markings are placed on the top
surface 1a of the golf club putter head 1 and the markings are in a
predetermined relationship to the putter face insert 3 and the
sweet spot 12. The preselected markings may comprise a first half
circle 13 and a second full circle 15 spaced from the first half
circle 13 by the distance "L". The diameter of the first half
circle 13 may be the same as the standard golf ball or it may be
greater or less than the diameter of the standard golf ball. The
second full circle 15 may be the same as the standard golf ball or
it may be greater or less than the diameter of the standard golf
ball. the first half circle and second full circle may be engraved
into the surface 1a of the golf club putter head 1 or it may be
otherwise marked thereon by any desired marking indicia.
[0013] A first straight line marking 9 is provided on the top
surface 1a at the edge of the striking face 2 parallel to the face
2 and along a diameter of the first half circle 13. A second line
marking 10 is provided along a diameter of the second full circle
marking and perpendicular to the first line marking 9 and extends
to the intersection 11 with the first line marking 9 to form a "T"
configuration. The intersection 11 of the first line marking 9 and
the second line marking 10 is centered above the sweet spot 12 on
the insert 3 of the striking face 2.
[0014] The golf club putter head 1 may be fabricated from metal,
such as aluminum, steel, titanium or the, like and may, if desired
be a forging. As shown in FIG. 5 to the rear of the insert 3 and
putter face 2 there may be provided a hollow portion 4. the hollow
portion 4 may be filled with additional material to provide the
desired weight of the golf club putter head 1 as well as to provide
the desired balance of the golf club putter head 1.
[0015] Referring now to FIG. 6, there is illustrated the use of the
golf club putter head 1 in striking a golf ball 14. As shown
thereon, the first half circle 13 and second full circle 15 aid the
eyes of the person using a putter with th golf club putter head 1
in aligning the golf ball 14 and the first half circle 13 and
second full circle 15. The "T" shaped marking 8 of the golf club
putter head 1 aids the eyes of the of the person using a putter
with the golf club putter head 1 to move the golf club putter head
1 in the correct direction toward the pin (not shown) to which the
golf ball 14 is to be directed.
[0016] Referring now to FIGS. 7 and 8, there is illustrated the
operation of the golf club putter head 1 of the present invention
in striking a golf ball 14 on a surface (not shown) which is not
level. In such a condition, the first half circle and the second
full circle 15 will appear as slightly oval to the person using the
golf club putter head 1 of the present invention. Such an
appearance aids the person in judging the correct direction to
strike the golf ball 14 taking into account the non level
surface.
[0017] While particular embodiments and applications of the present
invention have been above described an illustrated, the present
invention is not limited to the precise construction and
arrangements disclosed. Those persons knowledgeable in the art may
conceive of certain modifications, changes and variations in the
detailed embodiments disclosed above as illustrative, to suit
particular circumstances or products to be formed. The invention is
therefore not intended to be limited to the preferred embodiments
depicted, but only by the scope of the appended claims and the
reasonably equivalent apparatus and methods to those defined
therein.
