This application is a Continuation of PCT Application PCT/US2018/01806, filed on Feb. 13, 2018, which claims priority to U.S. Provisional Patent Application Ser. No. 62/600,034 filed on Feb. 13, 2017, all of which are incorporated herein in its entirety by this reference thereto.
BACKGROUND OF THE INVENTION (1) Field of the InventionThe present invention relates generally to the apparatus, design, and method of a putter head with a unique face design, body and flange design, variable weight system design, and adjustable sole plate that work individually and together to greatly improve the performance of the stroke of a ball by optimizing the transference of energy from the momentum of the swing; increasing the moment of inertia (MOI) and widening the area of forgiveness; improving aerodynamics; improving the coefficient of restitution (COR), properly adjusting the center of the horizontal axis of the putter head above the horizontal center of a ball; reducing the vertical lift while increasing the rise angle of a ball on impact; and vibration dampening resulting in a lower, resonant frequency and thus, softer touch, without loss of the audible sound generated at the moment of impact for improved tactile response.
(2) BACKGROUNDThe art of putting a golf ball on the green is a skill that challenges even the most advanced players. There are several variables that all contribute to a successful putt. A player must be able to successfully gauge distance, speed, terrain, and direction. To accomplish these goals and achieve maximum accuracy, traditional putters rely on a golfer's ability to strike the ball in the sweetspot (or the optimum strike zone which is typically centered with the horizontal and vertical axis of the center of the putter head), of the putter head. The game of golfing, and its related equipment, has continued to evolve in an effort to improve the effectiveness of players striking golf balls more accurately.
The two most prevalent styles of golf putters on the market (at the time of this patent application) are blade and mallet putters. Several putters include various methods to control sound, feel, vibration, force, momentum, and rotation. Although the differences between most putter heads within each category are extremely subtle, the ultimate purpose of these various designs is clear: improved control of the putter during the stroke (the act of swinging the putter to strike the golf ball). Better control over the swing and alignment of the head to the ball all contribute to accuracy. As mentioned in the related art, there are various types of putter head designs to accomplish these goals. However, in the present invention, not only the design and apparatus are unique, the method of design, method of assembly, and resultant effects are also uniquely greater than those of other putters on the market both individually and cumulatively.
There have been a number of patents related to the design of a putter head in general. U.S. Pat. No. 7,744,485 discloses a golf putter head with removable weights of the same size, located in the bottom of the putter. U.S. Pat. No. 3,143,349 discloses a golf club head with recesses to vary the weight of the heel and toe portions. U.S. Pat. No. 6,422,950 discloses a putter head with an interchangeable sole plate weight in the cavity of the putter. U.S. Pat. No. 6,224,497 discloses a putter head with a unique groove design on the face to reduce vibration. U.S. published application number 2008/0125240 discloses a putter head with a series of horizontal grooves on the face for a soft feel, reduced slippage, and better appearance.
U.S. published application number 2014/0148268 discloses a putter head with an adjustable ball striking face insert. U.S. Pat. No. 5,582,553 discloses a golf club head with an interlocking sole plate.
The present invention provides an innovative evolution in the design of putter heads utilizing a unique face design for vibration dissipation unlike any other. The weight system is unique in its design and layout providing benefits over conventional putters. The adjustable sole-plate is a completely unique design to which there is no comparative alternative. The three-tiered alignment siting system is a completely unique design. It can, thus, be seen that the present invention provides a novel putter head which provides more efficient energy transference; reduced vibrational impact; a vertical positioning tool; and a unique, customizable weight set, all of which contribute to a more controlled swing for the improved stroke of a ball.
The forgoing examples of related art and limitations related therewith in the art of golf clubs and putters, are intended to be illustrative and not exclusive, and they do not imply any limitations on the heat exchanger device and method described and claimed herein. Various limitations of the related art are already known or will become apparent to those skilled in the art upon a reading and understanding of the specification below and the accompanying drawings.
SUMMARY OF THE INVENTIONA putter head is provided that includes an overall design for the putter head wherein the main body having a substantially planar front face thereon, includes an angled configuration relative to the playing surface to optimize ball lift during contact with the golf ball. This angled surface, especially with horizontal and or diagonal grooves, and proper centering from an adjustable sole plate, on contact, more effectively transfers energy to the ball. In addition to this angled surface, the inclusion of one or both of horizontal recesses and diagonal recesses depending into the face of the club, also provide a means for reduction of vibration and improvement in the aerodynamics of the putter head.
A flange may be provided which includes four weight sockets adapted for engagement with any of a plurality of different sizes interchangeable weights therein whereby a balancing of the putter head may be customized to the individual user. Such adjustment can for individual users be employed for a widening an area of forgiveness, providing increased energy, optimizing momentum and force while increasing the MOI to prevent incidental rotation of the putter head about its vertical center axis or the vertical axis of the putter shaft.
Additionally included in a particularly preferred mode of the putter head herein is an adjustable sole plate configured to provide a means for height adjustment of the face of the club relative to the center of the ball as well as the putting surface. The putter has a desired impact spot or sweet spot at the horizontal center of the face in between the top edge and bottom of the face.
The adjustable sole plate provides the user a means to adjust a distance of a bottom contact surface of the putter from the horizontal line running through the sweet spot on the face of the putter. Such adjustment can be used to adjust the position of this sweet spot to each golfer to maximize accuracy by maximizing their ability to contact the ball on this sweet spot area.
This adjustable sole plate includes a sole plate post extending therefrom which is positionable to an infinite number of removably fixed engagements with the face of the putter, by translation of the sole plate post within a complimentary recess depending into the lower surface of the putter head. Translation of the sole plate post within the recess effectively changes the location of the bottom of the putter head which contacts the golf playing surface thereby adjusting the height of the center area of the putter head face relative to the center of a golf ball resting on the playing surface. Set screws or a threaded weight define releasable fasteners adapted for frictional engagement with the sole plate post are employable to removably secure the sole plate post in position which is one preferably which properly aligns the center horizontal axis of the putter head above the horizontal center axis of the ball, as a means to impart immediate topspin to the ball upon impact which results in reduced loft time, shorter landing distance, and longer roll time.
The sole plate post can also be configured to tilt slightly within the recess depending into the putter head to allow an angle adjustment of the extension away from the lower surface of the club. This angle adjustment allows the user to tilt the axis running through the center of the sole plate post, toward or away from the heel or the toe of the putter head. Such allows the center axis of the sole plate extending from the center of the sole plate up the sole plate post, to be adjusted to an angle either substantially perpendicular to the playing surface which positions both opposing ends of the sole plate distance substantially equal from the bottom surface of the putter head, or at an angle therefrom which places one end of the sole plate closer to the bottom surface of the putter head than the opposing end of the sole plate.
The putter head can be configured in multiple configuration all of which provide a significant improvement in ball trajectory from the face of the putter head once struck. In one preferred mode it may be configured with just the adjustable sole plate, and in another mode with just the inclusion of one or both of horizontal recesses or grooves and angled recesses or grooves which both depend into the face of the putter head, or in a particularly preferred mode, the putter head can include both the adjustable sole plate and one or both of the horizontal grooves and angled grooves.
Sides of both the grooves running at a diagonal angle and then horizontally can depend into the face of the putter head at two opposing sides extending toward each other at opposing angles. Preferably, the side surfaces of the grooves extend at an angle of substantially 60 degrees relative to the planar surface of the face of the putter head. By substantially is meant plus or minus 20 degrees. Both the horizontal and perpendicular grooves currently are preferred to be formed as an isosceles triangle, where the two sides of each groove depend into the face and extend at an angle of substantially 60 degrees to an intersection of the two sides. A gap forms an open end of each triangular groove running between the intersection of the two dies with the face.
The grooves so formed with two sides having substantially 60 degree angles relative to the face, have a perpendicular angle of an imaginary line running through the center equally between both of the two sides of either the horizontal or angled grooves. This imaginary line runs to open side or gap across the planar face. While other shapes of the grooves, such as rectangular, were tried in experimentation and did perform better than a putter with no grooves, it was the formation of both the horizontal and angled grooves in a triangular depression into the face which provided the most significant performance enhancement to a striking of the ball which ran straighter and faster with such triangular shaped grooves. The horizontal grooves and the angled grooves are positioned to surround the sweet spot of impact for the ball on the face of the putter. As is well known, a consequence of hitting the ball outside of the sweet spot on the face of a putter yields poor ball contact resulting in corresponding direction and distance errors of the rolling ball. Unexpectedly, angling the side surfaces followed by each of the triangular horizontal and/or angled groove depending into the face of the putter head, increased putting accuracy and enhanced the ability of the putter and user to continuously putt the golf ball and have it immediately roll on contact with the face of the club in straight line substantially perpendicular to the surface of the putter face. The inclusion of one or both of the horizontal grooves and diagonal grooves appear to have increased the area of the sweet spot on the club such that users had increased accuracy and roll with one or preferably both included. Enhancing the sweet spot, or at least making inaccuracy more forgiving, is desirable since if the ball encounters uneven surfaces causing it to later curve as it rolls toward the hole, insuring a straight line departure and roll from the club face, rather than an rolling therefrom at an angle to the club face, reduces the potential error in putting the ball into the hole.
Initially, forming a plurality of substantially parallel horizontal grooves across the face of the putter in-between the top edge and bottom edge of substantially equal length yielded a forgiving sweet spot to users and increased accuracy. By substantially parallel is meant within five degrees of running parallel to each other. Unexpectedly, additional accuracy gain was found by forming the plurality of substantially parallel horizontal grooves, where a longest horizontal groove is on the face of the club adjacent the bottom, and the shortest horizontal groove is closest to the top edge. Viewing from a position above or in front of the face of the club, the formation of the grooves in this manner appears as a shape of a pyramid. This configuration yielded additional gain in user accuracy for putting and is therefor most preferred.
Further, upon formation of the pyramid formation of the horizontal grooves, it was found that forming the plurality of diagonal grooves, to run at angles substantially parallel to an imaginary line running down the two sides of the pyramid shape formed by the plurality of horizontal grooves, yielded yet additional gain in accuracy during testing rather than forming the diagonal grooves along diagonal angles not running parallel to the sides of the triangle. Consequently, it is preferred that the plurality of diagonal grooves are positioned on both sides of the pyramid shape formed by the plurality of horizontal grooves of decreasing size, and that these diagonal grooves parallel the side of the triangle formed by the horizontal grooves on the side they are located.
In accordance with the present invention, the putter head is provided with a unique design which, while ornamental, is actually structurally configured to provide a high moment of inertia (MOI) along the vertical axis though the head's center of gravity which is achieved by the unique customizable weight design, face design, enabling a method of use that provides evenly dispersed energy transference and widens the area of forgiveness while reducing vibration and softening impact. Additionally, in accordance with the present invention, a golf putter head is provided with an adjustable sole plate that provides optimum positioning of the putter head and a golf ball to improve alignment performance during the stroke of a ball.
Accordingly, the putter head including a generally blade shaped body (however, this is not intended to limit the putter head to any particular size, type, shape, or configuration as the head may be sized and/or configured in numerous ways), defining a leading portion for striking a golf ball (face), a body, and a trailing portion (flange). The present embodiment is a putter head comprised of any materials (although it would most typically be a high impact, low weight, rigid metal or composite material, but is in no way limited to this), arranged in a unique design. The body is designed with a horizontally extended heel-foot, a vertically longer toe-shoulder and horizontally shorter toe-foot (from the center of gravity), and an angled portion of the upper heel-shoulder for the hosel. The bottom of the putter is convex, raising the horizontal center of gravity along the heel-to-toe axis. The unique shape of the body is sized to balance in-line with the shaft, providing continuity from the shaft through to the toe of the putter head which provides greater control and tactile feedback. An opening in the bottom of the body is designed to house an adjustable sole-plate and may be sized according to any adjustable sole-plate and sole-plate post design or assembly, although the optimum configuration is provided for in the present invention.
In accordance with another embodiment of the present invention, the flange and body width, from front to back, may be widened or lessened (front to back), in any quantifiable lengths, equal or unequal, creating an overall wider or thinner putter head. The wider putter head provides more weight and a higher motive force. An additional benefit of the wider head is that it can hold heavier weights which further improves the momentum in a swing for greater energy and accuracy for players needing more power in their swing. Additionally, the wider head and heavier weights provide a higher moment of inertia (MOI), similar to a large-head/club-style putter.
In accordance with another embodiment of the present invention, the putter head having a front face with a series of horizontal grooves in the optimum strike zone (known as the “sweet spot”) designed to improve the stroke of a golf ball. The finely mitered horizontal grooves on the face center, which are longer at the bottom than the top resulting in a triangle-shaped outline (although this is in no way intended to limit the horizontal groove length and design) help grip the ball on impact to improve static friction and vertically lift the ball out of its depression. The unique spacing and depth of the horizontal grooves are designed to more accurately capture as much surface area of the ball as possible without causing any additional lift beyond what's needed, thus minimizing overall loft while helping reduce vibration. The wider land (flat) area of the face provides better coefficient of restitution (COR) (which is the quantity of energy transferred from the head into the ball).
In accordance with another embodiment of the present invention, the putter head having a front face with a series of vertically slanted grooves on either side of the sweet spot, designed to improve the stroke of a golf ball. The finely mitered vertical grooves, which angle toward the center of the putter head at their top and further away from the center at their bottom, follow the triangular-like outline of the horizontal grooves in the center. The vertically slanted grooves reduce vibrational forces transferred across the face of the putter to the putter body, for a softer touch and improved tactile feedback. The reduced vibration also reduces wear and tear on a player's wrists from vibrations that are normally carried up through a putter shaft. As the vibration from the stroke of a ball travels across the face of the putter head, the grooves cause a dispersal effect, interfering in the pattern of the vibration. This, in turn, results in a lower, resonant frequency while the initial impact can be heard without any loss due to the wide land area of the face transferring a larger amount of energy to the ball than in typical putter heads. Additionally, the vertically slanted grooves are spaced with a wider land area (flat portion of the face), allowing more energy to be transferred to the ball. In conjunction with the weight system and distribution of energy across the face, the higher transfer of energy (including the additional energy provided by the weights), increases the putter's MOI and reduces the potential for rotation about the vertical center of gravity of the putter head or the center of gravity along the putter shaft.
In accordance with another embodiment of the present invention, the putter head in which the round, beveled edges on the outside of the face improve the aerodynamics of the putter head allowing for a more controlled swing due to reduced wind resistance (drag). This is not intended to limit the type of bevel or whether or not a bevel is used. Although putter heads generally travel short distances during a swing, slight fluctuations in the air can translate to a lot of wind resistance. This results in a loss of momentum and reduces the amount of energy available for transfer from the club to the ball, causing reduced speed and distance. Wind resistance can also contribute to the unwanted rotation of a putter head. The aerodynamic nature of this putter head thus reduces that potential and improves the directional accuracy of a stroke.
In accordance with another embodiment of the present invention, the putter head with four, weight sockets, which may or may not be threaded, on the back side of the flange to house 4 adjustable weights, where the 2 smaller weight sockets, which are of equal dimension, are equally spaced on either side of the center axis of the putter head and double as the locking mechanism for the adjustable sole plate; and the 2 larger weight sockets, which are of equal dimension, are equally spaced on either side of the center axis of the putter head. This is not intended to limit the type, size, or number of weight sockets as any additional amount of weights may also be used to provide the same results as claimed in the present invention. This is in no way intended to limit the weight sockets to a specific arrangement, dimensions, or configuration and the weight sockets may be attached using any method including, but not limited to screw-in sockets, adhesive, pressure, etc.
In accordance with another embodiment of the present invention, the putter head with four, weight sockets, which may or may not be threaded, accessible from the back side of the flange, housing weights that focus energy in the back to front direction from the forward momentum of a swing at 4 key points across the heel-to-toe length of the head, providing equal force across the majority of the face and widening the area of forgiveness by distributing equal amounts of force and increasing the moment of inertia (MOI). The weights focus the energy from the forward momentum of the swing in a linear motion parallel with the direction of the swing at 4 key points across the heel-to-toe length of the head, providing equal force across the majority of the entire face and thus widening the area of forgiveness.
Traditionally, striking a golf ball outside of the optimum strike zone (otherwise known as the “sweet spot”, or the vertical and lateral center of the putter head with the highest moment of inertia) causes a loss of energy (for example: as much as 16-20% of energy can be lost at 0.75 inches from the center of the head), and results in unwanted rotation of the putter head due to the reduced moment of inertia (MOI). The reduced energy causes a loss of distance, speed, and control. This occurs because a ball provides a counter-resistive force against the vertical, rotational axis of the putter head along its center of gravity. Depending on the MOI (the putter head's ability to remain stabilized versus rotating when this occurs), hitting a golf ball outside of the sweetspot typically causes the head to rotate away from the desired direction.
The stabilization provided by the forward energy of the weights maintains an amount of energy equal to the force typically only found in the sweet spot, along the face of the putter. Additionally, the improved distribution of energy allows for a higher coefficient of restitution (COR), which is the transfer of energy from the putter head to a ball, as the distributed weight system focuses energy along with the momentum energy of a stroke, widening the full range of effective power that can be transferred, across the majority of the face.
In addition to the above, the adjustable weights improve the COR and provide stabilized MOI by increasing the area of forgiveness closer to the heel-toe ends of the face under two principals: A) force trajectory and B) equalized dispersion of momentum. The offset balance of weights creates a virtual triangular line of force where the tip of the “energy” triangle (as further illustrated in the attached illustrations), extends well beyond the front face widening the area of equalized energy transference. The transferred momentum from swinging the golf club is improved by the unique-shape of the weights as highly focused energy, carrying the force of the swing perpendicular to the face, and by the even dispersion of weight (which is further enhanced due to the offset weight sizes). The shape of the weights is designed to provide more focused energy. The specific gravity of the weights may be adjusted according to the individual characteristics of each golfer by simply removing any one or a plurality of the currently inserted weights and replacing this with a more preferred weight or plurality of weights.
Another advantage of the unique weight system is how it interacts with the horizontal grooves on the face to reduce loft. As the ball achieves initial vertical lift, the weights will transfer energy through the body to the ball, along the horizontal axis of gravity, at just the right moment to convert the ball's vertical momentum into forward motion so that there will be approximately 1 degree of lift to 4 degrees of rise angle (during an optimum swing), decreasing the landing distance and increasing the rolling distance. In accordance with another embodiment of the present invention, the adjustable weights are comprised of any material and have different specific gravities made by adjustments to the core of the weights, which may be solid, or hollow, in any diameter thereof, as needed to customize the weights.
In accordance with another embodiment of the present invention, the putter head with a vertically adjustable sole plate that enhances the performance of putting a golf ball by aligning the horizontal center axis of the putter head higher than the center of gravity of a golf ball. The sole-plate post, which adjoins the sole-plate and putter head, is inserted into the bottom of the putter head, and the sole plate, may be of any size and type, and constructed in any manner such as injection molding, casting, or other appropriate methods.
Striking a golf ball above the centerline is important because 1) it more rapidly forces a forward topspin altering the trajectory of the ball into forward motion (achieving the optimized rise angle), and 2) the topspin provides better roll which allows the ball to grip the turf better and minimizes skid. The sole plate would typically be adjusted, depending on an individual's unique dimensions and/or preferences, so that the center line of the horizontal axis of the putter head sits just above the horizontal centerline of a ball. The sole plate is attached by any number of means, to the sole plate post and then inserted into the opening at the bottom of the putter head. The smaller weights of the weight system serve as a locking mechanism for securing the sole-plate and sole-plate post into place (although this is not intended to limit the number of methods for utilizing, creating, adjusting, or attaching the sole plate to the putter head). The method of construction and material of the sole-plate and sole-plate post may be of any type (although it would most typically be a high impact, low weight metal or composite material, but is in no way limited to this).
In accordance with another embodiment of the present invention, the putter head with a hosel that can be sized for receiving any size or type of putter handle (or shaft) which may or may not be threaded and may be designed for permanently attachable or interchangeably attachable shafts, is secured at an optimum angle to the putter head by any number of possible means. While the lie (angle) of the putter shaft to the head can be customized, the hosel is already designed at an optimum angle so the head is parallel with the ground, so adjustments can be made to the shaft as needed.
In accordance with another embodiment of the present invention, the putter head with a 3-tiered alignment site system comprised of a horizontal line in the front to back direction of the cavity, a horizontal line in the front to back direction on the upper ridge, and a site dot on the top of the putter head. All three sites provide a more highly accurate, visual reference by which the center of axis of the putter head (sweet spot) may be aligned with the center axis of a golf ball for the most optimum transference of energy and directional control. This is not intended to limit the type of style of alignment site used as it may be of any shape and dimension.
In accordance with another embodiment of the present invention, the putter head where the cavity in the flange is centered with the sweetspot to provide optimum balance of the head and works with the curved flange ridge design shown in the illustrations and smaller weights to focus energy from the stroke of a golf ball outside the sweetspot back into the center, thus reducing rotation of the putter head due to the higher MOI and widening the area of forgiveness. The curved flange ridge helps maintain the evenly distributed force in conjunction with the weight system.
In accordance with another embodiment of the present invention, the putter head with a body designed to dampen the vibrations from the strike of a golf ball, reducing the resonant frequency, creating a softer touch, and reducing the amount of vibration carried through the putter shaft without reducing the audible sound from the strike. The thickness of the metallic or composite materials that the putter head may be constructed from (although this in no way is intended to limit the types of materials that may be used), would most typically have higher quality internal friction, which is the capacity of a material to convert its mechanical energy of vibrations into heat that is dissipated. High-impact metal alloys designed to dampen vibrations are most often made of such materials.
There are many embodiments which fall within or may fall within the scope of the present invention. An effective example of one design in accordance herewith is to construct a putter head, using any number of methods available, to design a face with horizontal groove patterns to help grip the ball on impact to improve static friction and vertically lift the ball out of its depression.
The unique spacing and depth of the horizontal grooves are designed to create an uneven surface on the land area (flat portion of the face), where the grooves provide a virtual grip that assists in vertical lift and have been found in experimentation to increase the sweet spot area. When putting, a golf ball typically sits in a small depression which must be overcome during the stroke of the ball to ensure the most efficient, forward momentum. Traditionally, lifting the ball from its depression may be solely achieved by the power and angle of the putter head at the moment of strike along its horizontal axis and can result in too much upward lift (loft), that reduces the amount of roll time of a ball by creating a longer landing distance, higher vertical rise, a jump on landing, and backspin (which leads to skidding).
The horizontal grooves, in addition to dampening vibration and enlarging the sweet spot, assist in lifting the ball for approximately 1 degree of effective vertical lift. Traditional putters will have closer to 3 to 5 degrees of vertical lift. The reduced loft and increased rise angle will achieve the most optimum height to decrease the landing distance and cause the ball to roll more quickly. Additionally, vibrations caused when striking a golf ball interfere in the transfer of energy between the head and the ball.
The plurality of horizontal grooves and the shallowness of the grooves themselves, improves the coefficient of restitution (COR, or transference of energy), with a wider land area (surface area) capable of transferring more energy to the ball and resulting in a lower resonant frequency (in which lower resonant frequencies will dissipate more rapidly and thus reduce overall vibration in the putter head). The grooves themselves help to dampen residual vibrations by creating uneven paths for the vibrations to flow through. Additionally, the reduced vibrational frequencies create a softer ‘touch’, reducing wear and tear to a player's wrists since the majority of vibrations are unable to travel through the putter head and up the putter shaft. As vibrations are known to reduce tactile sensitivity in nerve endings, the reduced vibrations also improve tactile feedback for a player. The inclusion of diagonal grooves alone or in combination with the horizontal grooves also dampens vibration further and increases the sweet spot area for a user.

The weight sockets 15, 16, 17, and 18 (shown with the adjustable weights inserted) may be of any size or dimension but would be most typically designed as shown, correctly balanced with the design of the head such that the inserted weights properly distribute the energy of the momentum of the swing to increase the coefficient of restitution across the majority of the face of the head in the heel-to-toe direction, widening the area of forgiveness.
The overall configuration of the putter head body and all elements shown, may be made by any method, including but not limited to, casting, etching, routing, or engraving, with any number of decorative elements on any side of its body. The flange 20 and the body 23 may be made separately but would most likely be made together with the remainder of the putter head, as is shown in the current illustration. The weight sockets 15, 16, 17, and 18 may be made by any method, including, but not limited to, for example: drilling, routing, or casting. The material of the putter head body may be made from any material or composite material, although it would most likely be made from a high-impact, rigid metal alloy.
The hosel 14, which may be of any dimension, threaded or not threaded, may be made by any method such as, but not limited to, boring, casting, or drilling. Although the currently shown design is optimized for the maximum transference of energy, dampened vibrations, and widened area of forgiveness, it may be modified to any design and type that accomplishes one or more of these goals at the same or greater level. The method of making the body may be by any means, but would most typically be cast as a single unit to maximize the vibration dampening effects.
A width of the body from front to back is such that it provides the maximum amount of reduced vibration by (I) imparting more energy to the ball on impact, and (ii) having a rigid frame that transforms said vibrations to thermal energy. The length of the flange ridges 22 (which are the top portion of the flange, 20, on either side of the cavity, 21) in the heel-to-toe direction may be of any dimension. The flange ridges may include a cavity 21 having a length of any dimension. Although most typically the lengths would be as shown, centering the force of the stroke of a ball outside of the sweet spot back to the center of gravity of the head by concentrating the maximum amount of energy at that point.
The unique positioning of the alignment sites 90, 91, and 92 provide a 3-tiered approach to lining up the center of gravity of the putter head 3 with the center of a golf ball. When looking down at the putter head (as demonstrated in this illustration), all three alignments 90, 91, and 92 provide a much more accurate directional and central targeting arrangement that helps in centering a stroke with the sweet spot of the putter head.
The opening 33 which as noted is configured for translating engagement 63 (
In another embodiment of the present invention, the sole plate opening 33 may also be configured so that it continues through to the top of the putter head allowing for any design of sole post attached to the sole plate to be adjusted, inserted, or otherwise translated or manipulated from one or more points of the various sides of the putter head. The method of creating the sole plate opening 33 and shaping the bottom of the putter head 4 may be by any means, including but not limited to: casting, drilling, or laser cutting.
The depth of the opening 33 which slidably receives the sole-plate post 8, if constructed as separate units, may be of any depth and shape, depending on the shape and design of the sole-plate post 8, and sole-plate 7. The alignment of the sole-plate post 8 and sole-plate 7, in the current embodiment, is such that the sole-plate post 8 fits within the area of the putter head body closest to the face without interfering with the hosel. However, in another embodiment, the sole-plate post 8 may be aligned with the sole-plate 7 in any number of configurations, such as, for example, being centered in the front to back direction or shifted further to one side than the other in the left to right direction. The current illustration is not intended to limit this alignment or method of construction in any way.
The sole-plate 7 may be hollow or solid. It is not the intention of this illustration to limit the number of possible ways that the sole-plate post 8, may fit into the body of the putter head. The sole-plate post 8 may be inserted from the bottom or the top, depending on the variation of designs of the putter head designed to receive and support the sole-plate post 8. The sole-plate post 8 of the present invention is also designed to be removably fixed in place, using a releasable fasteners such as using two threaded screws or two smaller weights which have threads 59 (
In this illustration, the putter shaft 110 is shown at 1-3 degrees of swing angle in the direction 50 of the golf ball 111 after having struck the golf ball 111. The sole plate 7 has been adjusted in vertical height 51 so that the height of the horizontal axial center 54 of the putter head 3 represented by a dashed line, is higher than the center of gravity of the golf ball 111A.
As shown, it is centered with the center-axis of the heel-to-toe horizontal axis of the heel-toe weight sockets to demonstrate the effectiveness of the various parts working together whereby the center of force of the weights and the putter head center 54 are situated higher than the center of gravity of the golf ball 111A which is represented as a triangle with broken lines, in order to ensure a more rapid topspin, which is illustrated by a curved arrow, 53.
The depiction in
In
The widened area of forgiveness 68, shown filled with hash marks, is shown as an effect of using the method of the distributed weight sockets in the present invention and their focused energy lines, 60 and 61 and the result of the inclusion of one or both of, the horizontal grooves 10 and diagonal grooves 12 shown in
In another embodiment of the present invention, the sole-plate 7, may be a part of the putter head without the sole-plate post 8, attached directly to the putter head as a single, solid piece. However, such is not the most preferred as it eliminates the means for height adjustment of the face 1 to align with a ball. For example, by increasing the height of the putter head such that it has a sole-plate 7, whether as a separate or solid piece of the body, shifting the center, horizontal axis of the center of gravity of the putter head so that it will still strike a golf ball at a higher center of gravity. It is not the intention of the present illustration to limit the possible ways of utilizing a sole-plate 7, to adjust the height of the putter head's center of gravity, only that the adjustment of the putter head's center of gravity above the center of gravity of a golf ball is unique to the present invention insomuch as it forces a stroke of a putter to be higher than other putters, thereby causing a more effective alignment between the putter head and the ball. The design provided, including the current illustration, is provided as the most optimum design and configuration for weight distribution and effectiveness, including the effectiveness of the various other claims of the present invention.
The manner of constructing the weights 81, and the various weight or specific gravities 81B, may also be of any method or type. Additionally, as shown, the weight socket 16 opening up to the sole-plate post cavity so that the weight 81 can be used to secure the sole-plate and sole-plate post in place, although this is not intended to limit the additional methods by which the sole-plate and sole-plate post may be connected. Nothing in the present illustration is intended to limit the color or exterior, any markings or decorative variations that may be used in the method of design of the present invention. For example, a weight of 1 kilogram, may be marked: 1 kg (this number is only used for reference and not indicative of any set weight values). Other types of markings or variations thereof, including decorative and color-based, may be used. For example, the color coding of weight values such as 1 kilogram=red (this number and color are only used as an example and not indicative of any set values or colors).
For example, in the present disclosure hollowing the center of the weight, if made of a high-carbon alloy steel (for example only) along the cylinder of the body by the diameter of the total body would reduce the total specific gravity by 45%. The weight 82 may be constructed of any material or composite material, although most typically would be constructed of a high-impact, metal alloy. Although the weight 82, shape and design is optimized for the improvements claimed in the present invention, this is not intended to limit the shape, size, placement, or specific gravity of the weights. It is also not an intention of this illustration to limit the design of the weights 82 to threaded screw-in or other type of insert or the means by which the weights 82 would be held in place, which would most typically be, but is not limited to, screwing, adhesive, etc.
The double circle configuration on the head of the weights 82A is not intended to limit the manner of attaching the weights via a tool and may be of any size or type to accommodate any tool or method. The manner of constructing the weights 82 and the various specific gravities may also be of any method or type. Additionally, the present invention shows the weight socket 17, opening up to the sole-plate post cavity so that the weight 82, can be used to secure the sole-plate in place, although this is not intended to limit the additional methods of securing the sole-plate. Nothing in the present illustration is intended to limit the color or exterior, any markings or decorative variations that may be used in the method of design of the present invention. For example, a weight of 1 kilogram, may be marked: 1 kg (this number is only used for reference and not indicative of any set weight values). Other types of markings or variations thereof, including decorative and color-based, may be used. For example, the color coding of weight values such as 1 kilogram=red (this number and color are only used as an example and not indicative of any set values or colors).
Although the weight 80, shape and design is optimized for the improvements disclosed herein, this is not intended to limit the shape, size, placement, or specific gravity of the weights, 80. It is also not an intention of this illustration to limit the design of the weights 80, to threaded screw-in or other type of insert or the means by which the weights 80, would be held in place, which would most typically be, but is not limited to, screwing, adhesive, etc. The double circle recess method of design on the head of the weights, 80A, is not intended to limit the manner of attaching the weights via a tool and may be of any size or type to accommodate any tool or method. The method of constructing the weights 80, and the various specific gravities may also be of any method or type. Nothing in the present illustration is intended to limit the color or exterior, any markings or decorative variations that may be used in the method of design of the present invention. For example, a weight of 1 kilogram, may be marked: 1 kg (this number is only used for reference and not indicative of any set weight values). Other types of markings or variations thereof, including decorative and color-based, may be used, for example, the color coding of weight values such as 1 kilogram=red (this number and color are only used as an example and not indicative of any set values or colors).
