Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. provisional
application Ser. No. 61/257,521 filed Mar. 15, 2013 the disclosure
of which is hereby incorporated in its entirety by reference
herein.
TECHNICAL FIELD
[0002] This disclosure relates to a putter used in the sport of
golf.
BACKGROUND
[0003] One of the most important aspects of the game of golf is
putting. A wide variety of putters have been developed over the
years in an effort to provide every golfer with the putter that has
the desired feel and, hopefully, produces the desired result as
more one putts.
[0004] Conventional putters include a putter head attached to the
lower end of a shaft and a grip that is provided on the upper end
of the shaft. Putter heads may be one of many types of blades or
one of many widely varied types of mallets. Putters generally are
provided with a shaft that is of a fixed length with a grip
provided at the upper end of the shaft or provided at the upper end
with an auxiliary or intermediate grip provided below the grip at
the upper end.
[0005] There are four accepted putting styles that are currently in
use that are normally used with one of three different length
putters. A standard length putter used in the standard putting
style has a shaft that is approximately 800 mm to 900 mm and may be
shorter for women or children or longer for taller men. A belly
putter is used in the belly putting style and generally has a shaft
of 950 mm to 1100 mm in length and is designed to be anchored
against the stomach of a golfer. A long putter is used in the long
putting style and has a shaft that is longer than 1100 mm and is
designed to be anchored at the chest or chin of a golfer. A golfer
using "side-saddle" putting style also may utilize the long
putter.
[0006] Putters are generally purchased in standard combinations of
the head shaft and grip and are not adjustable or convertible in
any way. If a golfer, after purchasing a standard length putter,
wishes to try a belly putter or a long putter, he must purchase a
completely different putter.
[0007] The loft (vertical face angle) and lie angle (toe up/toe
down) of the putter head are normally fixed and cannot be adjusted
or calibrated. Golfers may change their putting stance so that the
golf ball is struck by the putter head either forward in the
stance, in the middle of the stance, or in the back of the stance.
The putter face becomes more positively lofted toward the front of
the putting stance and more negatively lofted toward the rear of
the putting stance. The loft is determined based upon where the
golf ball is to be struck by the putter or putter head.
Conventional putters do not have a loft angle adjustment
mechanism.
[0008] Golfers may wish to stand closer to or further from the golf
ball. As the point of contact of the putter head with the golf ball
moves further from the golfer's feet, the lie angle of the shaft
relative to the ground increases.
[0009] If it is desired to strike the ball with a putter head at a
location closer to the golfer's feet, the lie angle is reduced and
the shaft extends upwardly at a more vertical angle. With a
conventional putter, it is not possible to change the loft angle or
lie angle of the putter head relative to the shaft.
[0010] The putter head is normally attached to the shaft with the
blade of the putter square to the direction that the ball is to be
stroked. Some golfers may want to stroke the golf ball with an
open-face or a closed-face or compensate for a defect in their
putting stroke. However, conventional putters do not permit
adjustment of the putter head relative to the shaft and grip to
provide an open or closed face.
[0011] This disclosure is directed to solving one or more of the
above problems and other problems associated with conventional
putter designs as summarized below.
SUMMARY
[0012] According to one aspect of this disclosure, an under the arm
putter is disclosed that allows a golfer to use a long putter using
a putting stance for a traditional or standard sized putter.
Lodging a long putter under the armpit allows a golfer to put with
a normal stance while obtaining the benefits of a long putter or
belly putter preventing them from breaking their wrists while
putting.
[0013] According to one aspect of the present invention, an
adjustable and convertible putter is provided that may be adapted
for use with any of the conventional putting styles or with an
underarm putting style. The putter has a head connected to the
shaft with an adjustable connector that permits the lie angle and
the loft angle to both be adjusted within a wide range of angular
orientations. The lie angle of the putter may be adjusted to move
the toe up or down. The angular orientation of the face of the
putter may be adjusted to change the loft of the putter face which
allows the putter to lie on the ground in a functional manner with
the appropriate loft whether the putter is positioned in the front
of a player's stance, the middle of the stance, or in the back of a
putter's stance. The adjustable connector also allows the putter
face to be adjusted to a square, open or closed orientation.
[0014] According to another aspect of the invention, a connector
assembly may be provided at an intermediate location on the shaft.
A first portion of the connector assembly may be assembled to the
lower portion of the shaft with a second portion of the connector
assembly being attached to an upper portion of the shaft. The upper
portion of the shaft may be provided in a length appropriate for an
underarm putter, a belly putter, or a long putter.
[0015] According to another aspect of the invention, the shaft may
be interchanged and used with different types of putter heads. For
example, if a golfer wishes to convert from a two ball putter to a
mallet putter, but continues to use the same shaft and putting
style (belly, standard, long putter, etc.), the shaft may be easily
disconnected from one putter head and reconnected to a different
putter head.
[0016] According to yet another aspect of the present invention,
the adjustable and convertible putter disclosed may be used as a
standard putter, a belly putter, a traditional long putter, an
under the arm long putter, or as a side saddle putter. With each
different length and address position, the lie and loft angles may
be different but with the present invention both angles may be
adjusted with a single adjustment mechanism to the exact position
desired by the golfer. Depending upon the position of the ball
relative to the golfer's feet at address being centered, forward,
or rearward, it may be necessary to adjust the loft angle (vertical
face angle) of the putter head relative to the shaft. Depending on
the how far the golfer chooses to stand away from the ball at
address, it may be necessary to adjust the lie angle (toe up/toe
down) of the putter head relative to the shaft. The putter head may
also be rotated relative to the shaft to turn the head from a
square position to an open or closed position. Further, according
to the present invention, the shaft may be used and combined with
different heads to allow a golfer to convert from a mallet putter
to a two ball putter or from one mallet putter to another, or one
type of putter to another as desired.
[0017] According to a further aspect of this disclosure, a putter
is disclosed that comprises a shaft with a grip provided on at
least an upper end of the shaft. A head is connected to the shaft
by a connector that includes a first part attached to the shaft and
a second part connected to the head. The first part and the second
part define a ball joint connection between the shaft and the head
that are configured to connect the head to the shaft in a range of
angular orientations to permit a lie angle and a loft angle of the
head to be adjusted and fixed in a selected orientation relative to
the shaft.
[0018] The first part of the connector may comprise a ball end
including a cylindrical stub shaft adapted to be attached to a
lower end of the shaft and a spherical lower portion. The second
part of the connector may further comprise a receptacle that
defines a partially spherical surface and a threaded locking member
that may be loosened to change an angular orientation of the head
relative to the shaft and tightened to fix the angular orientation
of the head relative to the shaft.
[0019] The receptacle may further comprise an adapter having a
plurality of fingers on an upper end that have an outer surface
that form a frustum of a cone with an increasing diameter in a
vertical direction. The head defines an opening that receives the
adapter. A lower portion may define a threaded opening that
receives the threaded locking member. The threaded locking member
may be used to loosen the engagement of the fingers on the ball end
by extending the adapter out of the opening. The threaded locking
member may be used to tighten the engagement of the fingers by
drawing the adapter into the opening.
[0020] Alternatively, the receptacle may further comprise a socket
having a partially spherical surface on an upper end that is
secured in an opening in the head. The socket may define a threaded
hole that opens into the partially spherical surface. A threaded
fastener may be received in the threaded hole with the fastener
being untightened to loosen the engagement of the fastener on the
ball end. The threaded fastener may be tightened to fix the ball
end in place in the socket.
[0021] The opening in the head may include a shoulder that is
disposed above the spherical lower portion of the ball end when the
ball end is disposed in the opening in the head. The shoulder may
have a lower surface that is a concave ring that conforms to a part
of the spherical lower portion of the ball end. The socket may have
a threaded outer surface and the opening in the head may have a
threaded inner surface so that the socket is retained in the
opening by the threaded outer surface engaging the threaded inner
surface. A shoulder may be provided on a lower end of the socket
and a countersink bore may be defined in the lower surface of the
head. The socket may be screwed into the opening in the head to
engage the shoulder in the countersink bore.
[0022] The shaft may further comprise a lower portion approximately
800-900 mm in length and an upper portion approximately 150-200 mm
in length. A connector assembly may be provided that is adapted to
secure the upper portion of the shaft to the lower portion of the
shaft to adapt the shaft to be used as a belly putter. An
intermediate grip may be provided on an upper end of the lower
portion.
[0023] Alternatively, the shaft may further comprise a lower
portion and an extended length upper portion. A connector assembly
may be provided that is adapted to secure the extended length upper
portion of the shaft to the lower portion of the shaft to function
as a long putter
[0024] According to another aspect of this disclosure a putter is
provided that includes a putter head and a shaft connected to the
putter head. The shaft has a lower portion that includes a first
portion of a connector assembly and an upper portion that includes
a second portion of the shaft. A first grip may be provided on the
lower portion of the shaft below and adjacent to the first portion
of the connector assembly. A second grip may be provided on the
upper portion of the shaft in a spaced relationship relative to the
second portion of the connector assembly and adjacent to an upper
end of the upper portion of the shaft.
[0025] The upper portion of the shaft when used as a belly putter
may have a length LB that is less than the length of the lower
portion of the shaft. The upper portion of the shaft when used as a
long putter may have a length LL that is greater than the length LB
of the upper portion of the shaft of a belly putter.
[0026] The upper portion of the shaft may be selected from a first
portion that has a length LB that is less than the length of the
lower portion of the shaft, and a second upper portion of the shaft
that may have a length LL, wherein the first portion is
interchangeable with the second portion.
[0027] The shaft may be configured to connect the head to the shaft
in a range of angular orientations to permit a lie angle and a loft
angle of the head to be adjusted and fixed in a selected
orientation relative to the shaft. The shaft may be connected to
the putter head by a ball joint that further comprises a ball end
including a cylindrical stub shaft adapted to be attached to a
lower end of the shaft and a spherical lower portion. The ball
joint may further comprise a receptacle on the putter head that
defines a partially spherical surface and a threaded locking member
that may be loosened to change an angular orientation of the head
relative to the shaft and tightened to fix the angular orientation
of the head relative to the shaft.
[0028] The above aspects of this disclosure will be described in
greater detail below with reference to the attached drawings.

DETAILED DESCRIPTION
[0040] A detailed description of the illustrated embodiments of the
present invention is provided below. The disclosed embodiments are
examples of the invention that may be embodied in various and
alternative forms. The figures are not necessarily to scale. Some
features may be exaggerated or minimized to show details of
particular components. The specific structural and functional
details disclosed in this application are not to be interpreted as
limiting, but merely as a representative basis for teaching one
skilled in the art how to practice the invention.
[0041] Referring to FIG. 1, an underarm putter 10 is shown to
include a grip 12 at an upper end 14 of a shaft 16. A putter head
18 is shown at the other end of the shaft 16 with a golf ball 20 in
position to be stroked with the putter head 18. A golfer 24 is
shown in phantom line with the grip 12 of the underarm putter 10
disposed in the armpit 26 of the golfer 24.
[0042] Referring to FIGS. 2 and 3, a ball end 30 is provided on the
shaft. A cylindrical stub shaft 32 extends from the ball end 30 and
is received in the lower end of the shaft 16. An adapter is
generally indicated by reference numeral 36 and defines a ball seat
38 that is a concave, partially spherical surface within the
adapter 36. A plurality of fingers 40 are provided on the upper end
of the adapter 36. An outer surface 42 of the fingers, in
combination, form a frustum of a cone with an increasing diameter
in the vertical direction. A threaded opening 44 is defined by a
lower portion 46 of the adapter 36.
[0043] A receptacle 48 is defined within the putter head 18. The
receptacle 48 is partially defined by a tapered wall 50 that
receives the outer surface 42 of the fingers 40 when the adapter 36
is assembled to the putter head 18. A cylindrical wall 52 partially
defines the receptacle 48 and receives the lower portion 46 of the
adapter 36 when the adapter 36 is assembled to the putter head 18.
A countersink 56 is defined in the putter head 18 and extends
upwardly from the bottom of the putter head 18. A screw 58,
including a threaded shaft 60 and a head 62, is inserted through
the countersink 56 and into the threaded opening 44 defined by the
adapter 36. The screw 58 is tightened to draw the adapter 36 into
the putter head 18 until the screw 58 is tightened against a
shoulder 64 created by the countersink 56. As the screw 58 is
tightened, the outer surface 42 of the fingers 40 are drawn
downwardly into the receptacle 48 so that the fingers are forced
into engagement with the ball end 30 by the tapered wall 50 thereby
locking the shaft 16 to the putter head 18. To adjust the lie angle
or loft angle of the putter head 18 relative to the shaft 16, the
screw 58 is simply loosened and the shaft is repositioned at the
desired angular orientation, and the screw 58 is then tightened.
The putter head 18 may also be rotated relative to the shaft when
the screw 58 is loosened and then may be locked into a particular
open or closed orientation by tightening the screw 58.
[0044] Referring specifically to FIG. 3, the putter head 18 is
shown securely attached to the shaft 16. The ball end 30 is
received within the ball seat 38 and is secured to the shaft 16 by
cylindrical stub shaft 32. The screw 58 is shown fully tightened
against the shoulder 64 and the threaded shaft 60 of the screw 58
is fully tightened into the threaded opening 44 defined by the
adapter 36. When the screw 58 is fully tightened, the fingers 42
are forced into engagement with the ball end 30 as the outer
surface 42 of the fingers 40 are drawn downwardly against the
tapered wall 50.
[0045] Referring to FIG. 4, the loft angle adjustment of the shaft
16 relative to the putter head 18 is illustrated by the arrows
adjacent the shaft 16. The shaft 16 may be adjusted from the
upright orientation shown in solid line. If the putter head 18 at
address is moved back in the stance, the loft angle of the putter
may be adjusted to provide a more positive loft angle to compensate
for the upper end 14 of shaft 16 being in front of the putter head
18. If it is desired to position the ball more forward in the
golfer's stance, the loft angle of the putter may be adjusted to a
more negative loft angle to compensate for the upper end 14 of the
shaft 16 being behind the putter head 18.
[0046] Referring to FIG. 5, a putter head 18 and shaft 16 are shown
with the ball end 30 received in the putter head 18. The fingers 40
are shown drawn down into the putter head 18. The shaft 16 is shown
in phantom lines in two positions illustrating the ability to
adjust the lie angle (toe up/toe down) of the putter head relative
to the shaft 16.
[0047] Referring to FIG. 6, the putter head 18 is shown attached to
a lower portion 16LP of the shaft. The lower portion 16LP is
connected by ball end 30 to the putter head 18. A threaded
connector assembly 70 is shown as an exploded portion of the view.
The connector assembly includes a first portion generally indicated
by reference numeral 72. The first portion 72 includes a
cylindrical stub shaft 74 that is received in lower portion 16LP of

side of a lower body portion 78 from the cylindrical stub shaft 74.
A second portion 80 of the threaded connector assembly 70 includes
a cylindrical stub shaft 82 on one side of an upper body portion
84. The upper body portion 84 defines a threaded bore 86 in the
opposite end of the upper body portion 84 from the cylindrical stub
shaft 82. The cylindrical stub shaft 82 is received in an upper
portion of an underarm putter 16U to provide an underarm putter
such as that shown in FIG. 1. Of course, the orientation of the
threaded connector assembly 70 may be reversed with the threaded
stub shaft 76 extending from the bottom 84 with the threaded bore
86 being defined in the lower body portion 7;8.
[0048] FIG. 6 also illustrates the rotary adjustability of the
putter head 18 with two arcuate arrows near the lower end of the
shaft 16.
[0049] Referring to FIG. 7, a standard putter is illustrated to
include a putter head 18 in position for contacting a golf ball 20.
The putter head 18 is attached to a standard length shaft 16S for
use with a conventional putting style. The threaded connector
assembly 70 is provided at the upper end 14 of the shaft 16S. A
grip 12 is attached to the upper end 14 of the shaft 16S.
[0050] Referring to FIG. 8, a belly putter is illustrated that
includes a putter head 18 addressing a golf ball 20. The standard
length shaft 16S is connected to putter head 18 on its lower end.
The threaded connector assembly 70 connects the standard length
shaft 16S to a belly putter portion 16B. The belly putter
embodiment includes the belly putter portion 16B and includes the
standard putter grip 13 and an upper grip 12. Two grips are typical
with a putter used in the belly putting stance. The belly putter
may also be used as a side saddle putter depending upon the
golfer's preference.
[0051] Referring to FIG. 9, a long putter is illustrated that
includes a putter head 18 addressing a golf ball 20. The standard
length shaft 16S is connected to putter head 18 on its lower end.
The threaded connector assembly 70 connects the standard length
shaft 16S to a long putter portion 16L. The long putter embodiment
includes the standard putter grip 13 and an upper grip 12. One or
two grips are typical with a putter used in the long putting
stance. The long putter may also be used as a side saddle putter
depending upon the golfer's preference.
[0052] Referring to FIG. 1, an under-the-arm putter is illustrated
that is somewhat longer than a conventional long putter. The
standard length shaft 16S is connected by the threaded connector
assembly 70 to an under-the-arm portion 16U. The under-the-arm
putter embodiment may include two more grips 12, 13.
[0053] Referring to FIGS. 10 and 11, an alternative adjustable
putter is disclosed that has an adapter 90 including a socket 92
that has a partially spherical surface 94 on an upper end that is
secured in an opening 96 in the head 98. The socket 92 defines a
threaded hole 100 that opens into the partially spherical surface
94. A threaded fastener 102 is received in the threaded hole 100.
The fastener 102 is untightened to loosen an engagement of the
fastener 102 on the ball end 30 and is tightened to fix the ball
end 30 in place in the socket 92.
[0054] The opening 96 in the head 98 includes a shoulder 104 that
is disposed above a spherical portion 106 of the ball end 30 when
the ball end is disposed in the opening 96 in the head 98. The
shoulder 104 has a lower surface 108 that is configured as a
concave ring that conforms to a part of the spherical lower portion
106 of the ball end 30. The socket 92 has a threaded outer surface
110 and the head 98 has a threaded inner surface 112. When the
socket is retained in the opening 96 by the threaded outer surface
110 engaging the threaded inner surface 112, a shoulder 114
provided on a lower end 116 of the socket 92 is tightened against a
countersink bore 118 defined in a lower surface 120 of the head 98.
The socket 92 is screwed into the opening in the head 98 until the
shoulder 114 of the socket 92 engages the countersink bore 118.
[0055] While exemplary embodiments are described above, it is not
intended that these embodiments describe all possible forms of the
disclosed apparatus and method. Rather, the words used in the
specification are words of description rather than limitation, and
it is understood that various changes may be made without departing
from the spirit and scope of the disclosure as claimed. The
features of various implementing embodiments may be combined to
form further embodiments of the disclosed concepts.
