The present invention further relates to a custom-made golf putter configured by selecting an appropriate groove member according to gender, physical conditions, and green speed. The golf club includes a club head that forms a groove on a face that contacts a golf ball when the golf club is pushed, a shaft that is connected to the club head via a neck, and a grip that is provided at a distal end portion of the shaft on the opposite side of the club head.

Description

Technical Field

[0001] This invention relates to a golf putter with a putter face featuring sharp, conical protrusions that structurally suppress skidding, hopping, and sudden increases in the distance traveled due to unexpected backspin on the green during the putt, and which simultaneously cause the golf ball to rotate positively in the direction of travel during the putt. It further relates to a customized golf putter with appropriate groove components selected based on the golfer's gender (male or female) and physical condition (weight, height), or weather conditions (frost, snow, rain, dew) and green speed during the golf round. Background Technology

[0002] Golf is a sport that heavily relies on equipment; golfers can achieve good results if they use equipment that suits their characteristics. Therefore, customizing golf clubs is becoming increasingly important.

[0003] A golf putter is a tool used by golfers to drive a golf ball into the hole after the ball has landed on the green. It is the only golf club used in golf tournaments that does not send the ball into the air but instead rolls the ball to the target position.

[0004] In golf, putting shots account for about half (1 / 2) of all shots and significantly influence the score. Therefore, anyone can deeply appreciate its importance. However, the putting motion itself is very sensitive and difficult to master accurately. Even with practice, there is always unease and frequent mistakes. To overcome these problems, various innovative putters have been developed to improve aiming and ease of impact.

[0005] Traditional ordinary putter, such as Figure 1 The illustration shows a club with a shaft 200 made of metal or carbon fiber, a grip 300 located on the upper part of the shaft, and a clubhead 100 made of metal for striking a golf ball. The clubhead and shaft are connected by a neck. Furthermore, in the putting motion, it is important to correctly align the golf ball with the center of the putter face and strike the ball so that it rolls in a straight line, allowing it to move accurately towards the target.

[0006] However, traditional putters create a relatively wide contact area between the clubface and the ball upon impact. This leads to backspin or bounce, causing the ball to slide on the green and bounce, as well as sudden increases in distance due to action and reaction. Consequently, the ball's directionality becomes unstable due to sliding friction and irregular bounce, making it difficult to move the ball in the desired direction as distance changes. This phenomenon is further exacerbated if the grass texture is opposite to the ball's direction of travel. Furthermore, existing putters have an upward loft angle of approximately 3-4 degrees. Under these conditions, the actual angle may be larger at impact, depending on the golfer's posture. Moreover, for the reasons mentioned above, a larger loft angle increases the likelihood of the ball bouncing off the ground. Additionally, during the putt, due to action / reaction, the ball may experience backspin in one area and forward roll in the remaining area after impact.

[0007] Another traditional technique proposed to improve upon the problems mentioned above is to create a clubface that tilts towards the green at a negative (-) angle when striking the golf ball. This minimizes the contact area with the clubface at impact while simultaneously causing the golf ball to roll in a positive direction when the upper center of the ball is struck, preventing the ball from slipping or bouncing and thus guiding it in the direction desired by the golfer.

[0008] Putting is the process of covering a relatively short distance, but it is not only the golfer's physical characteristics and putting posture that determine the direction of the golf ball. The point of impact when the golfer hits the golf ball with the putter and the angle of contact when the golf ball is hit are also factors that determine the direction of the golf ball. Moreover, the amount of impact generated by the putter on the golf ball when hitting the golf ball is the main factor that determines the distance the golf ball travels.

[0009] As mentioned above, in order to reduce the number of golf shots through skillful putting, it is especially important to choose a putter that suits the golfer's personal characteristics.

[0010] However, despite past efforts to improve the market, most putters currently available are of limited specifications and offered uniformly. This prevents ordinary golfers from choosing finely categorized, custom-made putters based on gender, physical characteristics, and green speed. Instead, they are forced to settle for putters that are only roughly compatible with their own body type or characteristics. Furthermore, prior art (the aforementioned patent documents) that proposed improvements only suggested putter designs that were uniformly designed, rather than differentiated based on gender, physical characteristics, and green speed. Therefore, the inability to provide putters with finely categorized designs based on gender, physical characteristics, and green speed severely limits the range of optimal putters available to golfers.

[0011] Furthermore, as time goes by, physical conditions such as weight will change. Unless a golfer buys a new putter, it is common for the putter to become unsuitable for them. Therefore, it is necessary to simply replace the corresponding parts of the putter face and reassemble them appropriately.

[0012] Furthermore, the rolling shape and distance traveled by the golf ball vary significantly depending on the green speed during a round on the same golf course. Green speed typically varies depending on how short or long the grass is mowed, how firmly the green surface is compacted through rolling, and weather conditions such as humidity. Therefore, it is difficult for golfers to adjust the distance when putting.

[0013] As mentioned earlier, a combination of factors can prevent golfers from making accurate putting strokes. To overcome these problems more effectively, various (minor) modifications to the putter groove structure can be considered as a solution to address these diverse factors.

[0014] Prior art literature Patent documents (0001) Korean Patent Publication No. 10-1097772, a putter with a downward striking surface that can change the angle of impact on the ball in different intervals; (0002) Korean Patent Registration No. 10-1183428, Golf Club; (0003) Korean Patent Registration No. 10-1691753, Golf putter head and golf putter including the putter head; (0004) Korean Patent Publication No. 10-2273433, Improved directional and straight-line golf putter; (0005) Korean Patent Publication No. 10-2008-0004272, clubhead for golf putter; (0006) Korean Utility Model Registration No. 20-0150491, for a golf putter head. Summary of the Invention

[0015] This invention addresses the problems described above by providing a customized golf putter with sharp, conical protrusions arranged on the front side (the part that contacts the golf ball) of the putter face groove component. Upon impact, the golf ball deforms momentarily at the contact point between the metal protrusions and the plastic golf ball, as if the protrusions were piercing the contact area. After the groove protrusions disengage, the deformed portion of the golf ball returns to its original state (hereinafter referred to as "instantaneous piercing" on the surface of the protrusions and the contact area). Instead of slipping or popping out, this precisely drives the golf ball's rolling motion. Furthermore, the groove component can be integrally formed with the clubhead or designed and manufactured as a modular form that can be separated from / connected to the clubhead. The size and sharpness (referring to the inner angle of the apex of the conical protrusion) of the groove component can be designed and manufactured in various ways to allow for the selection of grooves suitable for the golfer's gender or physical condition.

[0016] Another objective of this invention is to provide a customized golf putter that utilizes the arrangement of tapered protrusions formed on the front side of the groove component to precisely construct the groove component so that, upon impact, the golf ball's rolling force is immediately activated by the instantaneous contact described above, and the angle between the clubhead surface and the shaft centerline is horizontal (180 degrees). This prevents the initial contact phase between the groove component and the golf ball from causing hopping or backspin, resulting in immediate rotation in the direction of travel after impact, thus forming roll generation.

[0017] Another object of the present invention is to provide a customized golf putter that utilizes the arrangement of tapered protrusions formed on the front side of the groove component to make the groove component ingeniously constructed so that the rolling driving force of the golf ball is immediately activated by the instantaneous engagement as described above when the putter strikes the ball, and the appropriate groove can be easily selected and replaced on the golf course according to the green speed.

[0018] Technical solution As an embodiment of the present invention to achieve the above-described objectives, preferably, as a golf putter comprising a clubhead with a groove formed on the face that contacts the golf ball during a putt, a shaft connected to the clubhead via a neck, and a grip located at the end of the shaft on the opposite side of the clubhead, (1) the clubhead has a shaft and a groove component; (2) in order to produce a momentary puncture effect during a putt, the front side of the groove component (the part that contacts the golf ball during a putt) is provided with a cone-shaped arrangement of protrusions having a needle-like structure with sharp apexes; (3) the arrangement of the protrusions of the groove component is based on the golfer's gender (male, female, male). (4) The groove component is made into a modular form that can be separated from or connected to the clubhead shaft; (5) The shape of the protrusions forming the groove component has a cone or pyramid shape, and the angle between the corner (131b) of the first protrusion (131) and the corner (133a) of the adjacent second protrusion (133) is formed by a certain angle between 60 degrees and 120 degrees.

[0019] In another embodiment of the present invention, to achieve the objectives described above, preferably, in the customized golf putter described above, the size of the conical protrusions forming the groove component protrusions is such that the weight range of men is divided into multiple predetermined intervals from at least 45kg to 95kg, and the weight range of women is divided into multiple predetermined intervals from at least 40kg to 90kg, and the size of the conical protrusions is formed differently according to each weight interval of men and women.

[0020] In another embodiment of the present invention to achieve the above-mentioned objectives, preferably, as a customized golf putter, multiple grooves are provided. When the green speed exceeds a predetermined speed, a relatively lighter groove can be selected from the multiple grooves provided to reduce the impact of the putter on the golf ball. Conversely, when the green speed is slower than the predetermined speed, a relatively heavier groove can be selected from the multiple grooves provided to reduce the impact of the putter on the golf ball, and can be easily changed on the golf course.

[0021] In another embodiment of the present invention to achieve the objectives described above, preferably, in the customized golf putter described above, the face of the putter head and the shaft form a horizontal (180 degrees); the shape of the protrusions forming the groove component protrusion arrangement is a quadrangular pyramid shape, and the angle between the corner (131b) of the first protrusion (131) forming the protrusion arrangement and the corner (133a) of the adjacent second protrusion (133) is 90 degrees.

[0022] In another embodiment of the present invention, to achieve the objectives described above, preferably, in the customized golf putter described above, the arrangement of the pyramidal protrusions is such that, for men, the weight is divided into 10 segments in units of 5 kg, with the length of the bottom edge of the pyramidal protrusions ranging from 1.2 mm to 3.0 mm at intervals of 0.2 mm; for women, the weight is divided into 10 segments in units of 5 kg, with the length of the bottom edge of the pyramidal protrusions ranging from 1.1 mm to 2.9 mm at intervals of 0.2 mm.

[0023] Beneficial effects According to the putter of the present invention as described above, its advantage lies in that, during the putting action, the clubface angle is appropriately embedded into the surface of the golf ball, causing the golf ball to immediately rotate and roll in the direction of travel upon impact, thereby preventing the golf ball from slipping or jumping, and counteracting the resistance of the grass texture, thereby improving the ability to adjust direction and putting distance.

[0024] This invention provides a modular form that can be separated from and connected to the shaft of the putter, and various designs and fabrications are made for the arrangement of the conical protrusions formed on the front side of the groove component, so that golfers can choose the appropriate customized putter according to gender, physical condition or green speed, thus expanding the range of choices.

[0025] The customized golf putter designed and manufactured according to this invention causes a momentary puncture and bonding between the sharp protrusions (metal material) of the groove and the contact area of ​​the golf ball (plastic material) during the putt, resulting in a smooth roll of the golf ball. This allows the golfer to easily maintain direction and adjust distance, thus improving the stability of the putt.

[0026] The golf putter according to the present invention has the advantage that, by forming a horizontal (180-degree) structure between the clubhead face and the center line of the shaft with a groove structure having a tapered protrusion arrangement, the groove component and the golf ball can prevent the golf ball from hopping or backspinning at the initial stage of contact during the putt.

[0027] The golf putter of this invention, which allows for the optional separation or connection of modular grooved components, enables easy replacement of the face portion (part or the entire face) of the putter, even if the golfer's physical condition changes due to changes such as weight. This allows for the reconstruction of the putter according to the golfer's preferences to suit their physical condition, thus providing an economic benefit of owning a customized putter at a lower cost.

[0028] It can also accumulate data on the condition of the greens, the condition of the greens, or the greens of various golf courses that change with weather conditions such as humidity (accumulated using GPS and other positioning information), and select putting groove modules that match the actual condition of the greens, the condition of the greens, or the changes in green speed depending on weather conditions such as humidity during actual rounds, thus making it easier for golfers to adjust the distance when putting.

[0029] Each golfer's unique information (e.g., smartphone number, QR code, etc.) and the corresponding putting groove module information are automatically matched and transmitted to each golfer's personal information terminal (e.g., ordinary smartphone or dedicated putting terminal, etc.) so that each golfer can select the best putting groove after comprehensively considering their physical condition and the condition of the green.

Figure 2 Part (A) is a simplified diagram showing the front structure of the customized golf putter of the present invention. Figure 2 Part (B) of the text is a display of the above. Figure 2 A schematic diagram of the cross section along line A-A' in part (A).

[0035] In another embodiment of the custom golf putter 100, a grooved component 130 is located on the central surface of the shaft 110 between the toe 111 and the heel 113, and the shaft 200 is connected to the upper end of the heel 113 via a neck 210. Further, the grooved component 130 can be designed and manufactured to be fixedly attached to the shaft 110; more preferably, the grooved component 130 is detachable from the shaft 110 to allow for easy replacement of other grooved components as needed.

[0036] In a preferred embodiment of the present invention, the groove component 130 is located in the groove portion formed in the center of the shaft face of the shaft head 110. Groove fastening bolts 150a and 150b are clamped behind the shaft head 110 to connect and fix the shaft head 110 and the groove component 130. For this purpose, the shaft head 110 is provided with groove fastening through holes 115a and 115b. In the rear portion of the groove component 130, such as... Figure 5 As illustrated in part (B), nuts 135a and 135b are provided at corresponding positions for bolt fastening, so that the ends of bolts 150a and 150b are inserted and tightened at a predetermined depth. In addition, a scale 117 for adjusting direction is provided in the middle of the upper side (top) of the rod head 110.

[0037] Figure 3 It is used for explanation Figure 2 A schematic diagram of the head 100 structure of the customized golf putter of the present invention. Figure 3 Part (A) is a schematic diagram showing the planar and frontal structure of the pusher head of the present invention. Figure 3 Part (B) of the text is the... Figure 3 A schematic diagram showing the planar and back structure of the putter head in part (A). Figure 4 For the purpose of illustrating the above Figure 2 A schematic diagram of the head 100 structure of the customized golf putter of the present invention. Figure 4 Part (A) is a schematic diagram showing the shaft 110 portion of the golf putter of the present invention. Figure 4 Part (B) is a schematic diagram showing the groove component 130 of the golf putter of the present invention. Figure 7 Is the display of the Figure 2 A schematic diagram of the state in which the shaft 110 and groove component 130 of a custom golf putter head 100 are connected according to an embodiment of the present invention.

[0038] like Figure 3 Part (A) and Figure 7 As shown in the diagram, the front side of the groove component 130 located in the center of the shaft 110 (the part that contacts the golf ball during a putt) has an arrangement of tapered protrusions with sharp ends, and a neck fastening hole 119 is provided on the upper part of the root 113 side of the shaft. Furthermore, as... Figure 3 Part (B) and Figure 4 As shown in part (A), the shaft 110 has grooved fastening through holes 115a and 115b, so bolts 150a and 150b can be inserted into the rear side of the shaft to fasten the grooved component 130.

[0039] This invention provides various groove components 130 to allow golfers to select appropriate protrusion arrangements based on their gender or physical condition (weight or height, etc.), enabling them to choose groove components 130 that suit their needs to create a customized putter. Furthermore, this allows golfers to perform more stable and sensitive putting actions.

[0040] Table 1 To take into account the physical condition of golfers, the groove component 130 is arranged with protrusions. As a method to differentiate a golfer's individual physical condition based on actual circumstances, the standard weight corresponding to the height of Korean women and men can be referenced in Table 1. For example, in the table below, the standard weight for Korean women who are 150cm tall is 42.5kg, and for men it is 45kg. The standard weight for Korean women who are 190cm tall is 76.5kg, and for men it is 81kg.

[0041] As a preferred embodiment of the present invention, the standard weight statistics corresponding to the height of Korean women and men in Table 1 can be used to design groove components 130 with protrusions arranged in 5kg units for men and women, and provide various different types of groove component 130 structures as shown in Table 2 below, so as to select a structure that conforms to the gender and physical conditions (weight or height, etc.) of golfers.

[0042] The physical conditions of golfers in Table 2 below are based on weight, with males ranging from 45kg to 95kg in 10 stages. The results were obtained by conducting repeated putting experiments (more than 30 times per person) on multiple golfers in each stage. The length of the raised base of the pyramidal shape is preferably designed and manufactured to vary from 1.2mm to 3.0mm, depending on the weight range of the male golfers.

[0043] The term "women" refers to the results of repeated putting experiments conducted by multiple golfers (more than 30 times per person) across 10 weight ranges from 40kg to 90kg. The length of the pyramidal protrusion at the base is preferably designed and manufactured to vary from 1.1mm to 2.9mm, depending on the weight range of the female golfer.

[0044] [Table 2] On the other hand, the experimental results are based on an example of a pyramidal convex shape (with a square base, equilateral triangle sides, and the vertex located at the top of the center of the base). As another embodiment of the present invention, the groove component 130 can be designed and modified differently by using a different arrangement of cone-shaped protrusions than the above example, or even if the shape is the same, but the sharpness (internal angle of the vertex) of the cone-shaped protrusions is changed.

[0045] Therefore, if the groove component 130 has different protrusion shapes such as conical, triangular, pentagonal, or hexagonal, or if the sharpness (internal angle of the vertex) of the conical protrusions forming multiple protrusion arrangements becomes different, the standard value of the protrusion base length according to the experimental results of the golfer's gender and physical condition category will be different from that in Table 2.

[0046] Furthermore, even for a pyramidal protrusion, if it is a pyramidal structure with a different shape than the one used in the previous experiments, and if the vertex is not located on the upper part of the center of the base of the pyramid, but on a tilted side (for example, tilted to the right or downwards from the center of the protrusion), the standard value of the experimental result for the length of the base of the pyramidal protrusion will be different from that in Table 2.

Figure 6 Part (B) is used to explain the above. Figure 6 Enlarged view of the two adjacent conical protrusions 131 and 133, indicated by dashed lines in part (A) of the diagram.

[0048] When a putter strikes a ball, the force (impact) generated on the golf ball varies depending on the golfer's weight. Therefore, in one embodiment of the present invention, this is taken into account. The putter is designed and provided in various types by varying the size (base x height) of the sharp, conical protrusions on the groove component 130 of the putter head 100 according to the golfer's physical condition, thereby providing putters with structures suitable for different golfers. Here, the protrusions forming the arrangement of protrusions on the groove component can be designed to have a shape such as a cone or pyramid (triangular pyramid, square pyramid, pentagonal pyramid, hexagonal pyramid, etc.), and the angle between the corner 131b of the first protrusion 131 and the corner 133a of the adjacent second protrusion 133 is preferably formed at an angle between 60 degrees and 120 degrees, depending on the golfer's physical condition or the putter manufacturing process. More preferably, the angle between the corner 131b of the first protrusion 131 and the corner 133a of the adjacent second protrusion 133 forms a 90-degree angle, so that the clubhead face and shaft (centerline) of the groove component 130 with the quadrangular pyramidal protrusion arrangement are horizontally aligned at 180 degrees. This allows for positive spin from the point of impact towards the direction of the golf ball's travel during the putt, thus preventing the ball from hopping or spinning when it contacts the groove component. This is made possible by the instantaneous piercing and bonding phenomenon between the metal clubhead protrusion and the plastic golf ball at the contact point during the putt. Furthermore, at the point where the clubhead protrusion contacts the golf ball, the corresponding part of the golf ball undergoes a momentary piercing change in shape, as if the protrusion has pierced into the ball, so that the golf ball does not slip or bounce away at all, immediately generating positive spin from the moment of impact. Here, the degree to which the protrusion of the metal clubhead penetrates the surface of the plastic golf ball varies depending on the impact of the putt, the sharpness of the protrusion (the size of the inner angle at the vertex), the hardness of the golf ball, and its elastic modulus. Therefore, preferably, provided that the golf ball's relevant characteristics do not exceed the normal range, the greater the golfer's weight, the greater the sharpness of the groove protrusion, i.e., the inner angle at the vertex, and vice versa.

[0049] In addition, as another embodiment of the present invention, as described above, the greater the weight of the golfer, the larger the inner angle of the sharp apex of the groove protrusion; conversely, the smaller the weight of the golfer, the smaller the inner angle of the apex of the protrusion is, while providing at least two more options, so that the golfer can choose the groove weight that suits their preference according to the green speed, and thus make more precise putts.

[0050] For example, if the green speed exceeds a predetermined speed, a relatively lightweight groove can be selected from the multiple grooves designed to reduce the impact of the putter on the golf ball and tightened immediately on the golf course. Conversely, if the green speed is slower than the predetermined speed, a relatively heavy groove can be selected from the multiple grooves designed to reduce the impact of the putter on the golf ball and easily replaced on-site. Regarding the different types of grooves, if a fine selection is desired based on the golfer's preference, preferably more than five types are designed; if a simpler selection is desired, preferably two to four types of groove weights are designed. Furthermore, the selection should be tailored to the golfer's preferences (referencing past groove selection / scores under similar conditions).

[0051] The following describes a preferred embodiment of the adaptation information providing system of the present invention.

[0052] Golf club fitting is the process of adjusting clubs to suit a golfer's preferences through scientific analysis of the club's components and the golfer's individual physical characteristics and swing style. As mentioned earlier, putting shots account for approximately half (1 / 2) of the total number of shots in a golf game, therefore, putting club fitting is particularly important.

[0053] According to a preferred embodiment of the adaptation information providing system of the present invention, positioning information such as GPS can be used to store green data of each golf course, such as the condition of the green, the surface condition of the green, or the humidity, in a golf course enterprise server or a dedicated golf club adaptation service enterprise server, and continuously update it. Furthermore, taking into account the physical condition of the golfer during the round and the condition of the green, the system recommends the optimal putting groove module that best matches their condition.

[0054] Here, the optimal putting groove selection information provided by each golfer can be recommended based on each golfer's unique information (e.g., smartphone number, QR code, physical condition, etc.). More preferably, it can be based on real-time location information such as GPS, taking into account the green speed status information of each hole on the golf course, and then automatically matching the putting groove module. The recommendation information is then transmitted to the golfer's terminal (e.g., a regular smartphone or a dedicated putting adapter terminal). The information terminal that can be used is, for example, the golfer's terminal based on location services as described in Korean Patent Registration No. 10-1119634, or a known ordinary personal portable terminal (smartphone, etc.).

[0055] Furthermore, the function of automatically matching and recommending the best groove module for each golfer can be either a matching value for different state categories input (specified) by each golfer or a value recommended by an artificial intelligence (AI) based matching method. Here, AI-based matching means that when generating groove recommendation information using accumulated data from a golfer's past data or from multiple golfers with similar physical conditions and putting tendencies, deep learning technology or various known AI (artificial intelligence) technologies can be employed.

[0058] Industrial applications As described above, the putter of the present invention, when performing a putting action, causes the clubface angle to properly penetrate the surface of the golf ball, so that the golf ball immediately rotates and rolls in the direction of travel after being hit, thereby preventing the golf ball from slipping or jumping, and counteracting the resistance of the grass texture, thus improving the ability to adjust direction and putting distance.

[0059] This invention provides a modular form that can be separated from and connected to the shaft of the putter, and various designs and fabrications are made for the arrangement of the conical protrusions formed on the front side of the groove component, so that golfers can choose the appropriate customized putter according to gender, physical condition or green speed, thus expanding the range of choices.

[0060] The customized golf putter designed and manufactured according to this invention causes a momentary puncture and bonding between the sharp protrusions (metal material) of the groove and the contact area of ​​the golf ball (plastic material) during the putt, resulting in a smooth roll of the golf ball. This allows the golfer to easily maintain direction and adjust distance, thus improving the stability of the putt.

[0061] According to the present invention, the golf putter has a horizontal (180-degree) structure formed by the angle between the clubhead face and the center line of the shaft, which is provided with a groove structure with tapered protrusions. During the initial contact phase between the groove component and the golf ball, the golf ball can be prevented from hopping or backspinning.

[0062] According to the present invention, which allows for the optional separation or connection of modular grooved components, even if a golfer's physical condition changes, the face portion (part or the entire face) of the putter can be easily replaced, and the structure can be reconstructed to suit the physical condition according to preference. Therefore, it has the economic benefit of having a customized putter at a lower price.

[0063] It can also accumulate data on the condition of the greens, the condition of the greens, or the greens of various golf courses that change with weather conditions such as humidity (accumulated using GPS and other positioning information). By selecting putting groove modules that match the actual condition of the greens, the condition of the greens, or the changes in green speed depending on weather conditions such as humidity during actual rounds, golfers can make it easier to adjust the distance when putting.

[0064] In addition, it has the effect of automatically matching and transmitting each golfer's unique information (such as smartphone number, QR code, etc.) and the corresponding putting groove module information to each golfer's personal information terminal (such as ordinary smartphone or dedicated putting terminal, etc.), so that each golfer can choose the best putting groove after comprehensively considering physical conditions and green conditions.
