The golf hole 40 and the markers 42a, 42b, 42d, 42e are discriminated by respectively independent labels 44a-44e to facilitate the specification and selection of the related putter 21 having a prescribed characteristic for complementing the putting stroke.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a golf putter. More particularly, the present invention relates to a display assembly and a method for selecting a putter for allowing a user to select a putter.

[0002] Golf clubs are generally categorized into three distinct types: wood, iron and putter. Wood and irons are used to propel the ball in the air towards the green. Due to the long drive distances when using wood and irons, many golfers place greater emphasis on developing skills using wood and irons. as a result,
Many golfers tend to neglect putting where the ball stays on the ground and is generally short.

[0003] Putting, however, is an inseparable part of the golf game. For a given set of clubs, wood is sometimes used in any round of golf, and typically is not used per hole. Similarly, the number of times a particular iron in a set of golf clubs is used will vary depending on the distance the golf ball is hit. On the other hand, putters
It is actually used at each hole in the golf course for a given round of golf. Therefore, depending on whether or not the player can put the golf ball correctly, the overall score of the player in one round of golf is significantly increased or decreased.

Whether a golfer puts the golf ball correctly depends on various factors that make up the golfer's putting style (eg, golfer's stance, putting stroke length and speed, golfer's goal, and golfer's stroke). Direction of swinging the club between them). Most golfers tend to swing the putter so that the putter head follows an arc during the stroke. Depending on the combined shape of the arc followed by the putter head as well as other factors in the putting style, the golfer puts the golf ball correctly or puts the golf ball to the left or right of the desired target. Will be.

[0005] Most golfers tend to select putters using a random process that typically involves selecting a "feeling" putter even after trying various putters. This random selection process may, by chance, give a putter with properties that are particularly suitable for the golfer's putting stroke, but this is not always the case. That is, a putter that does not complement the golfer's stroke may be selected, or even the putter stroke may be deteriorated.
As a result, most golfers have no access to putters that have properties that best complement their strokes.

[0006] Manufacturers (ie, manufacturers) can design putters with certain preselected characteristics, but the "best" putter that complements a particular golfer may vary from one golfer to another. You will see that. The reason is that even if the pre-selected operating characteristics of the putter are total weight, shaft length, weight distribution, or any other factor, the best putter for a golfer is that of a golfer who varies greatly from golfer to golfer. It depends on the specific putting style. As a result, manufacturers can design putters with preselected characteristics that are appropriate for a given putting style, but there is no easy way for a golfer to find and select the correct putter.
The only known method proposed by the manufacturer is based entirely on the traditional adaptation method of choosing static criteria, such as attitude at address, positioning, etc.

[0007] For example, with the exception of some professional golfers, most golfers are unaware that putter weight distribution affects their putting stroke. Also, some golfers may prefer to use a putter with a certain weight distribution, but such preference is usually maintained until the putter is successfully puttered or the It's a time-consuming process of trying countless putters until it gives a “feeling like”. Furthermore, even if a golfer can putter better than using one putter with one putter due to the effect of weight distribution, there is also a possibility that a golfer without knowing a putter having a weight distribution that is not optimal for himself may also be possible. is there.

Accordingly, there is a need for an assembly and method that allows a golfer to systematically select a putter that has characteristics such as weight distribution and that complements the golfer's particular tendencies when putting golf balls. ing.

[0009] The Applicant has observed that when most intermediate and advanced golfers are unsuccessful in putting, they are "steadily unsuccessful". That is, such golfers tend to always put the ball to the left or right of the desired target.

A preselected property that can be used to correct the golfer's putting is the weight distribution of the putter head. The putter head's moment of inertia about the axis of the shaft that occurs during the putting stroke is the weight distribution of the putter head relative to the axis of the shaft,
More specifically, it depends on the shape of the putter head and how the mass is distributed. By changing the weight distribution of the putter (and thus by changing the moment of inertia about the axis of the shaft), the putter is used to move the putter head during a stroke, as described in more detail below. Directing along a path can be made easier or more difficult. In this manner, the weight distribution is selected to correct the golfer's putting style and to orient the club along a path during the stroke to more accurately propel the golf ball in the desired direction. To

Accordingly, one aspect of the present invention relates to a method for selecting a putter, the method comprising the steps of: (a) selecting one putter from an array of putters having different balances; (C) determining an average tendency of the golf ball to laterally deviate from a target based on the plurality of puttings; Selecting another putter that tends to correct the lateral bias and repeating steps (b) and (c) with the other putter; and (e) substantially eliminating the lateral bias. Repeating the above step (d) until a putter not shown is specified. The step (d) includes selecting a putter having a predetermined weight distribution to correct the relative rotation of the putter face during a stroke, and, when the putter is freely rotated in a horizontal position, its head. And additionally selecting a putter having a predetermined toe-down orientation.

[0012] Another aspect of the invention is a target.
Using a putter array arranged in a display defining at least one marker provided on a first side of the target and at least one marker provided on a second side of the target, Pertains to how you choose. This method includes the steps of (a) taking out a putter from the display, (b) putting a golf ball toward the target using the putter a plurality of times, and (c) placing the ball on the target or the marker. Determining the tendency to fly toward one of the markers; and (d) if the ball has a tendency to fly toward one of the markers, the steps (a), (b) and Repeating step (c). The step (d) includes a step of selecting a putter that tends to change the direction of the golf ball to a direction closer to the target, and further has a different weight distribution from the putter extracted in the step (a). It is desirable to include a step of selecting a putter. The step (d) preferably also includes a step of selecting a putter having a marker corresponding to the label determined in the step (c).

[0013] Yet another aspect of the invention is a row of putters,
A display assembly for putter selection, comprising a target, at least one sign provided on a first side of the target, and at least one sign provided on a second side of the target. In one embodiment, the row of putters includes putters each having a particular predetermined weight distribution. The rows of putters (arrays) are preferably composed of putters with markers to indicate that each has a certain specific weight distribution. The markers and markers preferably have the same color, the same symbol, the same shape, or a combination thereof. In one embodiment,
The assembly further includes a base portion with five indicia on the front surface, two of which are spaced apart on each side of the target, the other indicia corresponding to the target.

In one embodiment, the row of putters includes five putters, and these putters have a gradually changing toe-down direction in the row. The putters in the row are preferably configured to have a toe-down increment of about 20 °. For example, a face-balanced putter (that is, a putter with a toe-down direction of 0 °), a putter with a toe-down direction of 20 °, and a toe-
Putter with 40 ° down direction and 6 toe down direction
It is desirable to arrange a 0 ° putter and a putter with a toe-down direction of 80 °. The face-balanced putter and the putter whose toe-down direction is 20 ° are marked with markers corresponding to the signs located on the right side of the target.
In addition, a marker corresponding to the marker located at the target is attached to a putter having a toe-down direction of 40 °, and a putter having a toe-down direction of 60 ° and 80 ° is placed on the left side of the target. Preferably, a marker corresponding to the marker located is attached.

The above and other features of the present invention will be described below with reference to the drawings showing preferred embodiments, which are intended to illustrate the present invention. It does not limit the invention.

FIG. 1 is a perspective view of a putter selection assembly 20 constructed in accordance with a preferred embodiment of the present invention. The putter selection assembly 20 includes at least one
There are two putters 21 and a base portion 22 that is configured to sit on the ground when the putter selection assembly 20 is used.
Upright portion 26 extends substantially upward from base portion 22. The putter selection assembly 20 can be used to systematically select a particular putter 21 having predetermined characteristics (eg, weight distribution) that complement a particular putting stroke of the user. The putters described herein that complement the user's specific putting stroke, in conjunction with the user's actual stroke, are configured to allow the user to more accurately put the golf ball in the desired direction.

The display assembly (display assembly for putter selection) supports and holds at least one putter 21 that can be removed by the user.
The putter 21 includes a shaft 23, a handle 25, and a head 27. Preferably, a plurality of putters 21 are arranged on the putter selection assembly 20 as separate groups, each group having a predetermined common characteristic configured to have a predetermined effect on the result of the user's putting stroke. Composed of putters. The reference number 21 used herein is generally used to indicate any putter. Putters having a particular configuration are distinguished by subscripts a, b, c, d, or e, as described in more detail below. For clarity, the assembly 20 of FIG. 1 is shown supporting one putter 21 of each type.

Referring to FIG. 1, the base portion 22 of the putter selection display assembly 20 has a substantially flat front surface 30 and an opposing flat rear surface 32. The side surfaces 32a, 32b connect the front surface 30 and the rear surface 32 to each other. The base portion 22 also includes a top surface 36, which in the embodiment shown lies substantially parallel to the ground. Preferably, the base portion 22 has a substantially elongate shape, but as will be described, the base portion 22 can have any of a variety of shapes and dimensions.

As shown in FIG. 1, a pseudo golf hole 40 is located at the center of the front surface 30 of the base portion 22. This simulated golf hole 40 is preferably defined by a cylindrical surface 41 that coincides with the front surface 30 and forms a recess (ie, a void) in the base portion 22. This simulated hole provides a realistic putting goal and is easy for users to see. This pseudo golf hole 40 may be drawn on the front surface 30. Desirably, the size of this simulated golf hole 40 is larger than a standard golf ball and large enough to be visible from 10 to 20 feet away from the putter selection assembly 20. Simulated golf hole 4
0 also preferably has a diameter equal to the regular golf hole diameter.

As shown in FIG. 1, markers 42 are located on the front surfaces 30 on both sides of the pseudo golf hole 40. Marker 42 uses reference numeral 42 as a whole,
And are individually indicated using subscripts a, b, c, d, or e. In the illustrated embodiment, the front face 30 has a total of four
And two markers are provided on both sides of the pseudo golf hole 40. Marker 4
2, while using the putter selection assembly 20;
Whether the user intends to put the golf ball to the left or right of the desired target, and a proper putter 2 to complement the user's putting stroke
It is determined whether or not to attempt to systematically select 1 to effectively assist the user. Although not necessary,
Four markers 42 and a single pseudo golf hole 40
It is particularly advantageous to use Such an arrangement can be used to "put" the pad as described below without "cluttering" the space on the assembly or using the selection assembly 20 which is cumbersome for the user by including an excessive number of markers 42. Provide users with a way to measure trends. The long front surface 30 provides a large area for blocking the wrong golf ball while the display (putter selection assembly) 20 uses minimal floor space, while the short sides 32
base 2 in that a, 32b provides a narrow profile.

Pseudo golf hole 40 and marker 42
Are each identified by a unique indicator 44. This sign 44
Uses the reference number 44 throughout and the subscripts a, b,
Indicated using c, d, or e. The indicia 44 is used to facilitate identification and selection of an associated putter 21 having predetermined characteristics that complement the user's putting stroke. Therefore, as shown in FIG.
Labels 44a to 44e are provided on 1a to 21e, respectively.
e is added. In the embodiment shown in FIG. 1, the identification marker 44 is a single symbol located directly above each marker 42. However, these identifying markers 44 may be any type of marker that identifies the markers 42, such as identifying colors or shapes.

Referring to FIG. 1, a plurality of putter head receiving portions 46 are provided on the top surface 36 of the base portion 22. In the embodiment shown, the putter head housing 46
Are aligned in a row extending longitudinally along the base portion 22. As shown in FIG. 1, each putter head housing 46 is dimensioned to substantially accommodate the putter head 27 of the putter 21. Putter head storage section 4
6 is preferably a recess formed in the top surface 36. Alternatively, the putter head housing 46 may be defined by individual walls extending upwardly from the top surface 36.
The putter head housing 46 can also be defined by a marker drawn on the top surface 36.

Referring to FIG. 1, in the embodiment shown, the upright portion 26 of the putter selection assembly 20 includes a main post 48 extending upwardly from the top surface 36 of the base portion 22. The upright portion 26 also includes a second post (secondary post) 50, which is
It extends upward from the top surface 36 opposite to the position of the main post 48. A flat display surface 52 extends between main post 48 and second post 50. Any of various signs 53 such as a logo or motto may be displayed on display surface 52.

As shown in FIG. 1, the upright portion also includes a putter shaft receptacle 54, which extends between the main post 48 and the second post 50. The putter shaft receiving portion 54 has a plurality of slots 55.
And these slots are dimensioned to receive and hold the putter shaft 23 of the putter 21. As shown in the figure, the putter head 27 of the putter 21 is placed on the putter head receiving portion 46 and the shaft 23 is placed on the slot 55 of the putter shaft receiving portion 54 to store and display a plurality of putters 21. A putter selection assembly 20 can be used. Putter 21
May be stored and displayed in other ways, but the arrangement shown is particularly advantageous since it provides easy access to the putters 21 while allowing the putters 21 to be seen in relation to each other without confusion. is there. Alternatively, the putter selection assembly 20 may include shelves or pockets for storing the putter 21 in an upright or horizontal orientation. This putter selection assembly 20 also
A separate container or open tray for storing or displaying the putter 21 may also be included.

The putter selection assembly 20 can be used alone or in combination with a separate assembly.
Are systematically stored and displayed. In particular, the putter 21 is configured according to certain common characteristics that are configured to complement the user's particular putting stroke. The putters 21a to 21e are differentiated using the markers 44a to 44e. For example, a symbol or color corresponding to the identification mark 44 on the marker 42 can be given to the handle of each putter 21. Alternatively, putter 2
1 in separate compartments and each compartment has a sign 44
May be provided. In this way, the user can easily identify and select the putter 21 when using the putter selection assembly 20, as will be described in more detail below.

In a preferred embodiment, the putter selection assembly 20 also includes a test assembly 56 for supporting the shaft 23 of the putter 21 in a horizontal position so that a user can visually inspect the weight distribution of a particular putter 21. Including. In the embodiment shown in FIG. 1, the test assembly 56 comprises a cap 58 mounted on top of the post 48. This cap 58 is for the shaft 2
3 to accommodate the putter 21
Is horizontally supported so as to freely rotate around the axis of the shaft 23 together with the putter head 27. The putter head 27 rotates to a specific direction according to the weight distribution. For example, a putter head whose weight is concentrated on the toe portion will rotate such that the toe portion points downward in the "toe down" direction. Because putters that are evenly distributed in weight around the shaft are "face balanced," such putters rotate in a direction in which the putter head is substantially horizontally aligned. The test assembly 56 can take any of a variety of other structures for horizontally supporting the shaft of the putter 21.

As described above, the putter selection assembly 20 can be used to systematically select putters 21 having predetermined characteristics that complement a user's specific putting stroke. In a preferred embodiment, certain characteristics of the putter 21 relate to a particular weight distribution of the putter head 27. In particular, the weight distribution of the putter head 27 is pre-selected such that a moment of inertia around the axis of the putter shaft occurs. This makes it easier or more difficult for the user to close the face of the putter during a stroke, as will be described in more detail below, so that the user can use the moment of inertia of the The putting stroke can be corrected.

FIG. 2 is a top view showing the user putting the golf ball 59 toward the putter selecting assembly for a certain distance d. The putter head 27 follows various paths during the putting stroke, as indicated by arrow 61, depending on the particular putting style of the user. In extreme cases, the putter head 27 moves along a straight line during the stroke. However, most users swing the putter such that the putter head 27 follows an arcuate path during the stroke. The curvature of such an arc depends on various factors, such as the speed of the club, the length of the stroke, the particular anatomy of the user, and the like. The direction in which the ball rolls after colliding with the putter face is mainly determined by the combination of the angle of the putter face and the direction of the putter at impact.

The weight distribution of the putter 21 may be used to provide the putter 21 with a moment of inertia that makes it more difficult or easier for the user to close the putter head during the putting stroke. Thus, by providing the putter 21 with some weight distribution, the putter "resists" in the user's movement to close the putter head during the stroke.
You can make it. In general, the greater the percentage of the putter head at the toe and the greater the mass, the more the putter will resist closing the putter face during the stroke. Golfers who tend to close the putter face extremely at impact can correct the putt using a putter having a moment of inertia configured to resist closing of the putter head. Similarly, golfers who tend to open the putter face at impact can correct the putt with a putter having a moment of inertia configured to facilitate closing the putter head.

The putter selecting assembly 20 is used as follows. Referring to FIG. 1, the first step includes an operation of selecting and removing the putter 21 from the putter selecting assembly 20. As described above, the putters 21 are arranged in the putter selecting assembly 20 in various categories (ie, groups) corresponding to the putters 21 having predetermined common characteristics. Markers 44 facilitate identification of putters 21 having certain predetermined characteristics.

In a preferred embodiment, the putter 21c
Is identified by a sign 44c provided in association with the pseudo golf hole 40. The putter 21c preferably has a shape and a weight distribution that give the putter 21c a predetermined moment of inertia.

The putters 21d and 21e are labeled 44d and 4d respectively.
4e and provided in association with markers 42d and 42e. These putters provide a moment of inertia that makes the club head somewhat easier to close during a stroke as compared to the intermediate putter 21c.
It has a predetermined shape and weight distribution given to d and 21e. The putter 21e makes it easier for the putter head to close than the putter 21d. Therefore, putter 21d or 2
1e is suitable for correcting a stroke of a golfer who has a tendency to miss to the right of a desired target, according to the degree of the mistake.

The putters 21a and 21b correspond to the signs 44a and 4
4b and is associated with markers 42a and 42b. These putters have a shape and weight distribution that give the putters 21a and 21b a moment of inertia that resists closing of the putter head as compared to the intermediate putter 21c. The putter 21a has a greater resistance to closing the putter head than the putter 21b. therefore,
For golfers who tend to miss to the left of the desired goal, either putter 21a or 21b will be suitable, depending on the degree of the mistake. Putter 21a
Preferred geometries 21-21e will be described in detail later.

[0034] The user preferably initiates the putter selection process by first removing the putter 21c from the putter selection assembly 20. As described above, the putter 21c of the putters 21a to 21e
Has minimal effect on the putting stroke for most users. Although the user can start with another putter, starting with the putter 21c can increase the possibility of finding the optimum putter as quickly as possible. The user enters the putter 21a
Or, if you start at 21e, you may have to do more iterations until you find the right putter.

As shown schematically in FIG. 2, the user
Next, the golf ball 59 is placed at a certain distance d from the front surface 30 of the putter selecting assembly 20. The user preferably places the golf ball 59 directly in front of the simulated golf hole 40 such that the line between the golf ball 59 and the simulated golf hole 40 is orthogonal to the front surface 30.
Next, the user uses the golf putter 21 to put the golf ball 59 toward the front surface 30 of the base portion 22 (particularly, to target the golf ball 59 to the pseudo golf hole 40). The user must put the golf ball 59 with sufficient force to hit the front surface 30 of the base portion 22.

When the user puts the golf ball 59 toward the simulated golf hole 40, the golf ball 59 moves straight toward the simulated golf hole 40 or on the left side of the simulated golf hole 40. Or move to the right. The user can select the marker 44
Is used as a guide to determine how far away the golf ball 59 has been putted from the pseudo golf hole 40. The user preferably puts the golf ball 59 a plurality of times and determines the average position at which the golf ball 59 hits the front surface 30 of the putter selection assembly 20. In this way, the user can determine whether he or she has a tendency to put the golf ball to the right of the desired goal or to put the golf ball to the left of the desired goal.

The user is always required to simulate the golf hole 4
If the golf ball 59 is put straight against 0, the particular putter used is very likely to be the best putter for the user's stroke. In the above example, the putter 21c was the optimum putter.

Conversely, if the user always puts the golf ball 59 on the right or left side of the pseudo golf hole 40, the putter 2
A putter other than 1c is the optimum putter. That is, the user must select a putter that corrects his or her stroke so as to put more accurately. The putter selection assembly 20 advantageously assists the user in systematically selecting an appropriate putter 21 having a weight distribution that corrects the user's putting stroke and allows the user to more accurately put the golf ball 59. I do. When the user puts the ball, the putter 21 having the same marker 44 as the marker 42 closest to the average position where the golf ball 59 hit the front surface must be selected. Although not necessary, the user preferably removes such putters from the putter selection assembly 20 and performs a test to verify that the selection is correct.

For example, the user indicates that the average location where the putted golf ball 59 hits the front surface 30 is the marker 4
You may find that it is closest to 2e. Such users tend to put the golf ball well to the right of the desired target. Therefore, this user must take out the putter 21e with the mark 44e. The putter 21e has a predetermined characteristic (preferably, a weight distribution) for correcting a specific stroke of the user so that the user performs putting more accurately. Thus, the putter 21e complements the user's stroke by compensating for the user's tendency to putt to the right of the desired target.

If desired, the user can repeat the above steps until the golf ball 59 is always put into the simulated golf hole 40. At this point, the user has selected the putter 21 that optimally complements his or her stroke.

As mentioned above, in this preferred embodiment, certain characteristics of the putter 21 are related to the weight distribution of the putter head. 3A to 3E are plan views showing preferred embodiments of the putters 21e to 21a on which the respective heads 27e to 27a are rotatable about the axis of the shaft 23 on a surface (that is, the ground). . As shown, the putter head 27
Take various angles with respect to the horizontal direction according to the specific weight distribution of the putter head 27.

Referring to FIG. 3A, a putter head 27e having a face-balanced weight distribution is provided.
e. This weight distribution orients the putter head 27e substantially parallel to the horizontal direction when the putter 21e is hooked down as shown. For a right-handed putting user, the weight distribution of the putter head 27e makes it much easier to close the putter head 27e during the putting stroke as compared to the intermediate putter 21c. Therefore, the putter 21e is preferably used to supplement users who tend to put the golf ball to the far right of the target.

FIG. 3B shows that when the putter 27d is suspended as shown in FIG.
The head 27d has a weight distribution such that it is oriented at an angle (A1) of 0 °. Such putters are called "20 toe down putters." For right-handed users, the weight distribution of the putter head 27d makes it somewhat easier to close the putter head 27d during the putting stroke as compared to the intermediate putter 21c. Putter head 2
The 7d moment of inertia gives the putter 21d greater resistance to closed arcs than the putter head 21e. Thus, the putter 21d is preferably used to supplement users who tend to put the golf ball somewhat to the right of the goal.

FIG. 3C shows a state in which
A putter 21c having a weight distribution head 27c oriented at an angle (A2) of about 40 ° to the horizontal is shown. This putter is “putted down by 40 さ せ”
Called. The intermediate putter 21c is used as a standard for determining another putter. Thus, its moment of inertia obviously does not give the putter 21c any special resistance or ease to closing the putter head during the putting stroke. The putter 21c
It is preferred that the putter for most golfers be selected to have a weight distribution that is in the middle of the desired range of weight distributions. The applicant has adopted "4.
It was determined that "0 tow down putter" was preferred.

FIG. 3D shows that when the display is suspended as shown in FIG.
A putter 21b having a head 27b with a weight distribution oriented at an angle (A3) of about 60 ° with respect to the horizontal direction is shown. This putter is "a putter that has been down 60 toe"
Called. For right-handed users, the weight distribution of the putter head 27b is smaller than that of the middle putter 21c.
Provides a moment of inertia that somewhat resists closing of the putter head 27d during the putting stroke. therefore,
The putter 21b is preferably used to supplement users who tend to put the golf ball somewhat to the left of the target.

FIG. 3E shows a putter 2 having a head 27a.
1a is shown. As shown, the weight distribution of the head 27a is such that when the putter 21a is suspended, the head 27a
Are oriented at an angle (A4) of about 80 ° with respect to the horizontal direction. Such putters have a sufficient toe-down weight distribution. Of all putters 21a to 21e, putter 21a has a moment of inertia that provides the greatest resistance to closing of the putter head during the putting stroke. Therefore, the putter 21a is preferably used to supplement users who tend to put the golf ball well to the left of the target.

It is desirable that all the putter heads 27 have a weight distribution such that the toe-down direction increases by about 20 °. That is, the increase interval of the weight distribution between adjacent putters in the putter row is about 20 °. The head 27 preferably maintains a tolerance of ± 4 ° when manufactured. The 20 ° increment is determined to be sufficient to clearly distinguish the tendency to scatter laterally between each putter and to allow the golfer to select a reasonably optimal putter for the golfer's stroke. To provide a sufficient number of options (options).

FIGS. 4A to 8D show the putter head 27.
Preferred embodiments of each of a to 27e are shown below. The putter heads 27a to 27e have a predetermined weight distribution that gives each putter 21 predetermined characteristics that complement various types of putting. Although the particular shapes shown in FIGS. 4A-8D are not required, the illustrated putter heads 27a-27e each provide a predetermined weight distribution and maintain the appearance that most golfers find comfortable. It is preferable in that it does. This is important because the key to successful golf is the player's mental attitude.

As shown in FIGS. 4A to 8D, each putter head 27a to 27e has substantially the same base shape, and only the position of the hosel 80 on each putter head 27 is different. The weight distribution of the putter 21 is changed about the axis of 23.

FIGS. 4A to 4D are front and side views, respectively, showing a preferred embodiment of the putter head 27e.
It is a rear view and a top view. As described above, the putter head 27e has a face-balanced weight distribution.
The putter head 27e has a front surface (that is, a hitting surface) 64
, A rear surface (ie, a belt) 66, an upper surface (ie, a crown) 70, and a bottom surface 72. At one end of the putter head 27 is a heel region 74.
