Description

Technology Field

[0001] The present invention relates to a golf glove having a smooth outer surface and an inner palm area and / or finger area, and in particular, to a golf glove in which the contact areas are surface-treated smoothly so as to provide optimal friction in the contact area between the inner surface of the glove and the palm, and the contact area between the outer surface of the glove and the grip portion of the golf club, when a user wears the glove and holds a golf club. Background Technology

[0002] Humans live their lives engaging in various types of exercise.

[0003] Among them, golf is also included. Golf is generally believed to have originated in Scotland in the 15th century.

[0004] Although forms of play similar to modern golf existed in ancient China, Rome, and the Netherlands, modern golf developed as an aristocratic sport in Scotland, where its rules were established; it was then globalized through the British Empire and is now a globally beloved sport and an official Olympic event.

[0005] Golf is a sport that can be enjoyed for a lifetime regardless of age or gender. Since it takes place in nature, it provides both healing and exercise, and can frequently be utilized as a means for business and socializing. Furthermore, because skill improvement is visible, it offers great joy in self-development.

[0006] To enjoy this type of golf, you must be equipped with not only golf clubs, including drivers and irons, but also golf balls, golf gloves, and shoes.

[0007] Here, golf gloves are not merely accessories but play an important role that significantly impacts a golfer's performance and stability.

[0008] Golf gloves help you grip the club firmly and stably, increasing the contact force between the palm and the club compared to bare hands. Additionally, they prevent the hands from slipping due to sweat, moisture, or rain, enabling a stable swing; they protect the skin of the palms and fingers from friction generated during repeated swings, preventing blisters or injuries; and maintain a consistent grip, ensuring swing consistency.

[0009] When a user strikes a golf ball while wearing a golf glove and holding a golf club, frictional force and torsional force act between the contact area of ​​the inner side of the golf glove and the palm, and between the contact area of ​​the outer side of the golf glove and the outer side of the golf club, respectively.

[0010] The inner surface of the glove absorbs sweat between the hand and the glove to prevent slipping, and it is designed to fit snugly to the curves of the fingers and palm, securing the golf glove so that it does not move loosely.

[0011] Between the glove and the golf grip, the glove functions to improve grip strength, prevent the club from slipping out of the hand even during a strong swing, and distribute the impact at the moment of impact across the entire hand to aid in accurate shots.

[0012] In conventional technology, most golf gloves lack separate surface treatment or pretreatment in the area that contacts the palm and grips the golf club; instead, uneven structures or protrusions are formed on the surface to improve grip, or anti-slip treatment is applied only to specific areas.

[0013] For example, Korean Registered Patent No. 10-1358647 (published on February 7, 2014) discloses a technology that provides excellent grip by forming nano hairs on both sides of a fabric for golf gloves and treating their height uniformly. This technology focuses on securing grip by imparting similar surface characteristics to both sides of the fabric.

[0014] However, conventional golf gloves have the following limitations. First, if the focus is on preventing slippage between the glove and the golf grip, the palm may slide inside the glove, compromising a stable grip. Second, applying excessive friction to the inner surface to prevent palm slippage can make putting on and taking off the glove inconvenient or cause discomfort to the hands during prolonged wear. Third, when gloves are manufactured from a single fabric, it is common practice to apply the same surface treatment to both sides; consequently, it is difficult to simultaneously optimize the different functional characteristics required for the inner and outer surfaces (e.g., appropriate friction with the palm, strong friction with the grip).

[0015] Therefore, there is a need to develop a new golf glove that effectively prevents slippage between the glove and the golf grip during a swing, while simultaneously preventing the palm from slipping inside the glove to provide optimal grip and comfort. In particular, technology capable of implementing these dual functions using a single fabric while maintaining a smooth and uniform appearance is still lacking.

[0016] Therefore, it would be desirable to more effectively pre-treat or surface-treat the inner area of ​​the golf glove that contacts the palm to increase friction during instantaneous impact and prevent deformation due to twisting.

[0051] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0052] For convenience of explanation below, the ‘inside’ or ‘inside’ refers to the space in the golf glove (1000) where the user’s hand can be attached, and the ‘outside’ or ‘outside’ refers to the area in the golf glove (1000) that forms the exterior and is exposed to the outside when the user wears the golf glove.

[0053] A golf glove (1000) according to one embodiment of the present invention, as illustrated in FIGS. 1 to 7, comprises a grip contact friction part (1300, see area corresponding to 'X' in FIG. 2 and 'X' in FIG. 6) provided to be in contact with the grip part (150) of a golf club (100) held by a user and a glove body (1100) forming an exterior, wherein the golf glove (1000) preferably comprises: a palm contact friction part (1500, area corresponding to 'A' in FIG. 6) coupled to an inner palm area of ​​the glove body (1100) so as to be in contact with the user's palm when worn by the user; and a finger contact friction part (1700, area corresponding to position 'C' in FIG. 6) coupled to an inner finger area of ​​the glove body (1100) so as to be in contact with the user's palm-side fingers when worn by the user.

[0054] Additionally, it is preferable that the surfaces of the grip contact friction part (1300), the palm contact friction part (1500), and the finger contact friction part (1700) are surface-treated more smoothly than the area where the back of the hand of the inner finger of the glove body (1100) contacts and is not surface-treated.

[0055] In addition, the material of the grip contact friction part (1300) includes sheepskin, and it is preferable that the friction coefficient of the surface includes a range of 0.6 to 0.7.

[0056] In addition, the sheepskin is micro-perforated, and it is preferable that the perforation diameter be in the range of 0.3 to 1.2 mm and the perforation density be in the range of 15 to 20 holes / cm².

[0057] In addition, the material of the palm contact friction part (1500) includes sheepskin or synthetic leather, and it is preferable that the friction coefficient of the surface includes a range of 0.5 to 0.6.

[0058] In addition, the material of the finger contact friction part (1700) includes sheepskin or synthetic leather, and it is preferable that the friction coefficient of the surface includes a range of 0.6 to 0.7.

[0059] In addition, it is preferable that the finger contact friction part (1700) be provided on the middle finger, ring finger, and little finger.

[0060] Additionally, it is preferable that the finger contact friction part (1700) and the palm contact friction part (1500) are overlapped and sewn inside the glove body (1100), and then a plurality of ventilation holes (1800) are formed through the finger contact friction part (1700) or the palm contact friction part (1500) to allow air to pass through.

[0061] In addition, it is preferable that the thickness of the area where the glove body (1100) and the finger contact friction part (1700) and the glove body (1100) and the palm contact friction part (1500) overlap is less than 0.65 mm.

[0062] Additionally, it is preferable to include a palm contact friction part (1500) or a groin contact friction part (2100) in the shape of a pad with a smooth surface, which is coupled to the inner side of the glove body (1100) and corresponds to the area where the user's palm or thenar eminence comes into contact when the user wears the golf glove (1000).

[0063] The golf glove (1000) has the function of preventing twisting, impact, or slipping that occurs during the process of swinging the golf club (100) while the user wears it and holds the grip portion (150) that wraps around the upper part of the club shaft (1300) of the golf club (100) and strikes the golf ball to send it to a desired position or direction, and can also have the effect of having a beautiful aesthetic sense.

[0064] Here, the glove body (1100) is a conventional glove that forms the exterior of the golf glove (1000) according to the present invention and covers the user's hand. In addition, among the glove body (1100), when the user holds the grip portion (150) while wearing the golf glove (1000), the area of ​​the user's hand that comes into contact with the grip portion (150) is designated as the grip contact friction portion (1300) (refer to 'X' indicated by the dotted line in FIG. 6). That is, the glove body (1100) and the grip contact friction portion (1300) are made of the same material, surface treatment, and thickness, and a part of the glove body (1100) is referred to as the grip contact friction portion (1300).

[0065] The raw materials constituting the material part can be broadly divided into natural leather and synthetic materials.

[0066] Natural leather includes Cabretta leather, a type of sheepskin commonly used, and cowhide leather. In this embodiment, the material of the glove body (1100) including the grip contact material part (1330), the finger contact material part (1730), and the palm contact material part (1530) includes sheepskin fabric.

[0067] Here, sheepskin is soft and thin, and fits well on the hand when worn, making it the most preferred material by tour pros. It has good sweat absorption and an excellent feel, which can provide the best grip, but it is expensive and susceptible to sweat and moisture, raising concerns about its durability.

[0068] Cowhide leather is thicker, more durable, and cheaper than cabretta, but it has the problem of being somewhat dull and thick.

[0069] Synthetic materials in the materials section include PU (polyurethane) synthetic leather, polyester / nylon mesh, and spandex (Lycra).

[0070] PU (polyurethane) synthetic leather can produce a texture similar to leather, has excellent durability and water resistance, and is inexpensive, but it is stiffer than leather and may have a less pleasant texture.

[0071] Polyester / Nylon mesh is primarily used on the back of the hand to ensure breathability and elasticity, and is often produced in a blend with leather.

[0072] Spandex (Lycra) can be inserted between the fingers and on parts of the back of the hand to increase elasticity and improve comfort.

[0073] Meanwhile, the palm area uses Cabretta leather to provide an optimal grip, and the back of the hand uses synthetic materials (polyester, spandex) to improve breathability and is lightweight; it is widely used for professional or high-end models.

[0074] The grip coating layer (1350), palm coating layer (1550), or finger coating layer (1750) are each characterized by having a smooth surface treatment as a part that comes into direct contact with the grip portion (150) and the palm side.

[0075] It is preferable that the grip coating layer (1350), palm coating layer (1550), and finger coating layer (1750) be treated with Nappa coating to obtain a smooth effect, but if necessary, Nappa coating may be applied only to the grip coating layer (1350).

[0076] When Napa coating is applied, the surface of the coating layer (1350, 1550, 1750) becomes smooth and uniform, and the glossiness is added, giving a luxurious feel.

[0077] Napa coating can form a thin protective film (PU (polyorethane) or resin, etc.) on the surface to reduce the absorption of water and sweat and improve friction resistance and wear resistance. Since excessive Napa coating can result in a slippery or artificial feel, it is desirable to make the grip coating layer (1350) thinner than the palm coating layer (1550).

[0078] It is desirable that the surface roughness of the layer to be coated (standards such as KS B 0161) be in the range of Ra (arithmetic mean roughness) of 0.05 to 0.2 μm, and the coating thickness be in the range of 0.1 to 0.3 mm. This is because if the surface roughness is less than this, it is too slippery, and if it is greater, it is too rough; and if the coating thickness is too thin, it cannot perform its intended function, and if it is too thick, it is difficult to prevent slipping.

[0079] Here, the adhesive index is a property indicating how well the glove surface or intermediate layer adheres. In particular, in a golf glove (1000), it is directly related to the frictional force with the grip portion (150) or the adhesive stability between the coating layer or the intermediate layer (not shown). Simply put, it is a numerical representation of the degree to which the hand and the grip remain securely attached without slipping.

[0080] In addition, it is desirable that the adhesive index of the palm contact friction part (1500) be higher than the adhesive index of the finger contact friction part (1700). This is so that when the user removes the golf glove (1000), the finger area is more tightly attached than the palm area, allowing the golf glove (1000) to be separated from the hand more easily.

[0081] In this case, a golf glove according to the prior art has an uneven surface for anti-slip purposes on the outer side (the part exposed to the outside or in contact with the grip) of a single leather layer and an irregular inner surface with a leather-like surface on the inner side (the inner area where the hand is inserted).

[0082] FIG. 2 is a drawing showing a state in which a palm contact friction part (1500) is coupled to the palm area, and FIG. 7 is a drawing showing a state in which, in addition to the grip contact friction part (1300), palm contact friction part (1500), and finger contact friction part (1700), a padded ridge contact friction part (2100) that contacts the thickly raised thumb ridge area on the palm side of the thumb is coupled inside the glove body (1100) of a golf glove (2000) according to another embodiment.

[0083] It is desirable that the surface roughness of the layer to be coated (standards such as KS B 0161) be in the range of Ra (arithmetic mean roughness) 0.05 to 0.2 μm, and the coating thickness be in the range of 0.1 to 0.3 mm. This is because if the surface roughness is less than this, it is too slippery, and if it is greater, it is too rough; and if the coating thickness is too thin, it cannot perform its intended function, and if it is too thick, it is difficult to prevent slipping.

[0084] Each contact friction part (1300, 1500, 1700) is provided with a contact material part (1330, 1530, 1730) that serves as the material and a coating layer (1350, 1550, 1750) that is smoothly treated on the surface of each contact material part (1330, 1530, 1730).

[0085] And, if necessary, an intermediate layer (not shown) may be included between each contact material part (1330, 1530, 1730) and the coating layer (1350, 1550, 1750).

[0086] As described below, the intermediate layer may differ in material, function, etc., but is formed of silicon microparticles or includes a nanoceramic coating treatment. Additionally, the intermediate layer may be formed by mixing silicon microparticles and a nanoceramic coating.

[0087] For example, the thickness of the intermediate layer is in the range of 1 to 5 μm, and the coefficient of friction is preferably in the range of 0.3 to 0.4 when dry and 0.2 to 0.3 when wet.

[0088] An intermediate layer having these materials and characteristics can improve wear resistance and provide optimized friction.

[0089] Meanwhile, according to another embodiment, the material of the intermediate layer is formed from natural latex to form a plurality of fine pores, and it is preferable that the thickness is in the range of 140 to 190 μm, the size of the formed pores is in the range of 10 to 50 μm, and the tackiness index is in the range of 4.8 to 5.2 (a range that is not too sticky and does not cause discomfort to the hands).

[0090] Here, the adhesiveness index is a property indicating how well the glove surface or intermediate layer adheres. In particular, in a golf glove (1000), it is directly related to the frictional force with the grip portion (150) or the adhesive stability between the coating layer and the intermediate layer. Simply put, it is a numerical representation of the degree to which the hand and the grip remain securely attached without slipping.

[0091] These other intermediate layers have the effect of improving skin adhesion and increasing or optimizing breathability due to numerous fine pores.

[0092] Meanwhile, a golf glove according to the prior art has an uneven surface for anti-slip purposes on the outer side (the part exposed to the outside or in contact with the grip) of a single leather layer and an irregular inner surface with a leather-like surface on the inner side (the inner area where the hand is inserted).

[0093] On the other hand, the golf glove (1000) according to the present invention has a smoothly treated coating layer (1350, 1550, 1750) formed on the surface of the contact material portion (1330, 1530, 1750) as described above.

[0094] FIG. 2 is a drawing showing the state in which the second contact friction part (1500) is coupled to the palm area, and FIG. 8 is a drawing showing the state in which the second contact friction part (1500) is coupled to the palm area and the thumb area, respectively.

[0095] The process of manufacturing each contact material part (1330, 1530, 1730) is outlined as follows. The contact material part includes natural sheepskin fabric from Italy or Indonesia, and these fabrics are selected and washed to remove impurities. Then, an activation process for surface treatment is performed.

[0096] That is, the fabric of each contact material part (1330, 1530, 1750) has oil, fine contaminants, and uneven protein structures remaining on the surface even after washing, so if the oil, etc. are left as is, dyeing, coating, and adhesion of the adhesive layer do not work well and durability is reduced.

[0097] Therefore, the fabric surface is subjected to activation treatment, and representative methods include chemical activation, physical activation, and enzymatic treatment.

[0098] One of the chemical activation treatment methods is a weak acid-alkali treatment that slightly modifies surface proteins to allow dyes and coatings to adhere well, and another is an oxidizing agent (H₂O₂, ozone, etc.) treatment method that can remove organic contaminants and impart hydrophilicity (the property of being easily wetted by water) to the surface.

[0099] One of the physical activation treatment methods is plasma treatment, which finely abrades the surface and provides hydrophilic groups (-OH, -COOH, etc.) to improve adhesion and coating properties, and another method is corona discharge, which introduces active groups to the surface using electrical discharge.

[0100] One of the enzymatic activation methods is the use of proteolytic enzymes, which can remove unnecessary proteins from the epidermal layer to form a smooth and uniform surface.

[0101] One of the methods for forming an intermediate layer is a method for forming a silicon-based microparticle layer, which is as follows.

[0102] The solution forming the intermediate layer preferably comprises 60 to 70 wt% polydimethylsiloxane, 20 to 25 wt% silica nanoparticles, 5 to 10 wt% crosslinking agent, 1 to 2 wt% catalyst, and 3 to 7 wt% solvent.

[0103] Here, silica is preferably elliptical nanoparticle with an average particle size in the range of 1 to 5 μm.

[0104] The composition thus prepared is evenly sprayed onto the surface using a high-pressure spray gun. After this spraying process, it is dried for about 30 minutes at a temperature of 80 degrees, for example, in a forced-circulation oven.

[0105] And in the case of nanoceramic coating, it is preferable that the solution composed comprises 15 to 20 wt% alumina nanoparticles, 10 to 15 wt% zirconia nanoparticles, 8 to 12 wt% polyvinyl butyral binder, and the remainder being ethylene glycol monobutyl ether.

[0106] In this case, it is preferable to perform dip coating, which is a method of immersing the fabric in a solution and then withdrawing it, and then dry it at 120 degrees for 45 minutes using an automatic temperature-controlled curing oven, for example.

[0107] In other words, the results of the test conducted after first forming the silicon particle layer using the method described earlier, and then forming the nano-ceramic coating layer, are as follows.

[0108] The result measured with a friction coefficient measuring instrument (applying JIS K 6264-2 standard) is 0.7 ± 0.05 in dry condition and 0.55 ± 0.05 in wet condition.

[0109] Here, it is desirable to optimize the coefficient of friction, etc., by controlling the silica particle size or concentration and the coating thickness.

[0110] Next, another intermediate layer undergoes a process of natural latex roller coating and vulcanization, followed by micropore foaming and control.

[0111] It is preferable that the solution contains 70 to 80 wt% natural latex (60 wt% solids), 10 to 15 wt% tackiness improver (rosin-based resin), 2 to 3 wt% vulcanization accelerator, and 1 to 2 wt% stabilizer.

[0112] It is preferable to coat the latex solution with a precision roller having uniformity, and the vulcanization conditions are preferably within 60 ± 5 minutes at 100 degrees.

[0113] It is preferable that the composition of the blowing agent includes 50 to 60 wt% polyurethane resin, 3 to 5 wt% blowing agent (azodicarbonamide), 1 to 2 wt% surfactant, and 0.5 to 1 wt% catalyst.

[0114] The material is processed in a foaming chamber at 140 degrees for about 20 minutes. As a result of this processing, the pores formed in the second intermediate layer (1530) can be formed in the range of 10 to 50 μm, and these sizes may vary depending on the temperature and time.

[0115] The water vapor permeability test of another intermediate layer was conducted according to KS K 0594 and is 8 cm³ / cm² / s or higher, preferably 8 to 12 cm³ / cm² / s.

[0116] As a result of the adhesion test, the 90° peel strength was found to be 2.5N / 25mm or higher.

[0117] And the comfort sensory test received a somewhat high score of 4.2 on an average scale of 5.

[0118] In addition, after forming this intermediate layer and another intermediate layer, the surface is smoothed.

[0119] These intermediate layers and other intermediate layers may not be created as needed. An intermediate layer is applied to the grip contact friction portion (1300), and another intermediate layer may be applied to the palm contact friction portion (1500), finger contact friction portion (1700), or pubic contact friction portion (2100).

[0120] And in the process of smoothing the surface, both sides are first polished equally. The polishing begins with coarse polishing and gradually progresses to finer polishing. That is, it is desirable to polish starting with a large grit size of abrasive paper (e.g., 1000 grit - average particle size 9㎛) and gradually moving to smaller grits, such as 2000 grit and 4000 grit.

[0121] After completing this polishing process, a nappa coating treatment is applied to smooth the surface using a mixture of acrylic and polyurethane solutions. The coating is applied in two stages and cured at 100 degrees (the 'degree' indicating temperature at the beginning or end means 'Celsius') for 40 minutes.

[0122] The manufacturing process of a golf glove (1000) having this configuration is described in detail with reference to FIG. 5 as follows.

[0123] A method for manufacturing a golf glove (1000) according to one embodiment of the present invention involves preparing the raw materials of each component into a large-sized fabric through the process described above (S110).

[0124] Next, a coating layer is formed on the material part (which is identical to the grip contact material part (1330) as described above) of the raw material for the glove body (1100) that has been finally processed, and this coating layer becomes a grip coating layer (1350) and is cut to a set size (S120). At this time, it is cut to a size that forms the palm, back of the hand, and thumb, respectively.

[0125] The material of the grip contact material part (1330) includes high-quality sheepskin or synthetic leather. The thickness of the grip contact material part (1330) is preferably 0.3 to 0.5 mm.

[0126] As explained above, the material of the grip contact material part (1330) includes sheepskin and is finely perforated, and it is preferable that the perforation diameter is in the range of 0.3 to 1.2 mm and the perforation density is in the range of 15 to 20 pieces / cm².

[0127] Then, a grip coating layer (1350) is formed on the surface of the grip contact material part (1330) (S120). It is preferable that the friction coefficient of the grip coating layer (1350) be in the range of 0.6 to 0.7. If it falls outside this range, there is a risk that the frictional force in contact with the grip part (150) will be too low or the stickiness will be excessive.

[0128] These grip contact material parts (1330) can increase the contact friction force (see ‘first contact friction force’ in FIG. 2) between the glove body (1100) and the grip part (150), thereby reducing slippage, twisting, etc. between the glove body (1100) and the grip part (150).

[0129] The palm contact friction part (1500) is composed of a palm contact material part (1530) and a palm coating layer (1550) formed on the surface of the palm contact material part (1530), and after forming the palm coating layer (1550), it is cut to a set size (S130).

[0130] The palm contact material part (1530) is high-quality sheepskin leather and has a thickness ranging from 0.2 to 0.35 mm, with a more preferred thickness of 0.3 mm.

[0131] It is preferable that the friction coefficient of the palm coating layer (1550) be in the range of 0.5 to 0.6. This structure can reduce slipping or twisting between the palm and the palm contact friction part (1500). For example, when a set external force is applied to the palm contact friction part (1500), it was confirmed that in the case of the prior art, slipping of about 3.8 mm occurred, whereas in the case of the present invention, slipping of about 0.3 mm occurred. In this case, the grip contact friction part (1300) also operates, so that slipping and twisting between the surface of the glove body (1100) and the grip part (150) can be reduced.

[0132] The finger contact friction part (1700) is composed of a finger contact material part (1730) and a finger coating layer (1750) formed on the surface of the finger contact material part (1730), and after the finger coating layer (1750) is formed, it is cut to a size set corresponding to each finger size (S140).

[0133] The finger contact material part (1730) is preferably made of a material capable of absorbing shock, for example, with a thickness of 0.25 mm and a pressure dispersion rate in the range of 35 to 40%. This material can disperse pressure applied to the finger and absorb shock, so fatigue can be reduced by about 35 to 45% even when worn for a long time.

[0134] The finger coating layer (1750) preferably has a friction coefficient of about 0.6 to 0.7 and may be provided with air holes or an uneven pattern as needed. With this structure, strong friction can be generated in the area in direct contact with the grip portion (150), and at the same time, fatigue of the finger can be reduced. The mechanical interlocking effect between the finger surface and the finger coating layer (1750) can be maximized. In this case, the grip contact friction portion (1300) also operates so that slipping and twisting between the surface of the glove body (1100) and the grip portion (150) can be reduced.

[0135] In addition, the palm contact friction part (1500) and the finger contact friction part (1700) can increase the contact friction force (see ‘second contact friction force’ in FIG. 2) between the palm (see ‘A’ in FIG. 6) and the finger (see ‘C’ in FIG. 6) and the corresponding grip part (150), thereby reducing slippage, twisting, etc. between the palm and finger and the palm contact friction part (1500) and the finger contact friction part (1700).

[0136] Next, the palm contact friction part (1500) and the finger contact friction part (1700), which have undergone the S130 and S140 processes, are sewn into the palm side grip contact material part (1330) that has been cut to form the palm of the glove body (1100) that has undergone the S120 process (S150). Then, a plurality of ventilation holes (1800) are formed to allow air to pass through the palm contact friction part (1500) and the finger contact friction part (1700) (S150). The formation of these ventilation holes (1800) can be performed after the glove body (1100) is completed, as needed.

[0137] Next, the palm-side grip contact material part (1330) that has undergone the S150 process is sewn together with the back-side material part to complete the glove body (1100) (S160).

[0138] Finally, before packaging, a finishing process is performed to remove foreign substances generated during the work process (S170).

[0139] And, during the process of a user wearing the golf glove (1000) according to the present invention and striking or swinging a golf ball with a golf club (100) to send the golf ball in a desired direction and distance, power and stability are concentrated on a specific finger rather than all fingers.

[0140] In particular, for right-handed players, the three fingers of the left hand—the Middle, Ring, and Little / Pinky—account for 70 to 75% of the total grip force. The contribution and role of each finger in grip force during a swing, based on the left hand, are as follows.

[0141] First, the little finger contributes more than 27%, is the core of the power grip, the last line of defense against club slippage, and is known to maintain 110% pressure during the swing.

[0142] Next, the ring finger contributes about 23% and is known to be responsible for power transfer and maintaining grip stability.

[0143] Also, the middle finger contributes about 25% and forms the central axis of the grip and the main power transfer.

[0144] The remaining index and thumb fingers together account for about 4%, function as directional control and sensory feedback, and are known to have minimal power transmission.

[0145] These contents have the following effects.

[0146] It has the permanence of forming an unbroken pressure distribution line from the middle finger to the little finger, and can completely block the phenomenon of the club spinning freely at the top of the backswing and at impact, thereby strengthening the ulnar side, and can optimize interlocking by relieving friction or pressure concentration in the little finger area, improving the sense of unity between the two hands by 35%.

[0147] The effects of the present invention are explained as follows according to the process of wearing a golf glove (1000) according to the present invention and swinging a golf club (100).

[0148] First, the address and takeaway phases are the starting phases of the swing, so it is advisable to hold the grip lightly with a 4 / 10 level of pressure.

[0149] At this time, the material portion (1100) of the palm surface and the second finger contact friction portion (1700) fill the curvature of the palm (gap filling), so that the gap between the hand and the glove can be eliminated even with a weak grip. This provides the user with a sense of psychological stability.

[0150] The structure of the golf glove (1000) on the finger side interlocks with the texture of the club grip, allowing the weight of the club head to be fully felt with minimal force. This eliminates unnecessary tension in the arm muscles, thereby enabling a smooth takeaway.

[0151] Next, at the moment when the golf club (100) moves backward due to inertia and then transitions forward during the top of backswing and transition, the risk of the golf club (100) toorque or slipping in the hand is greatest.

[0152] At this time, the second contact friction part (1500) on the palm side blocks internal slip caused by sweat, thereby preventing the glove from rotating around the hand. The structure of the second finger contact friction part (1700) on the finger side, specifically the 110% pressure support of the ‘pinky’ and the second finger contact friction part (1700) combined with the material part (1100), can physically brake the overswing of the golf club (100).

[0153] Next, the downswing and lagging phases are the sections where centrifugal force is maximized (head speed of 100 mph or more).

[0154] In the palm contact friction area (1500), the phenomenon of the glove being pulled toward the fingers by centrifugal force is offset by internal friction. In the finger contact friction area (1700), the middle finger, ring finger, and little finger areas strongly pull the golf club (100), enabling power transfer without loss.

[0155] If even a minute slip of 1mm occurs inside the palm, the head face angle becomes distorted, but in the case of the present invention, such minute slip can be prevented to increase the probability of a square impact.

[0156] Next, the impact stage is the moment when an impact equivalent to 4 to 5 times the body weight is transmitted to the golf ball.

[0157] In the palm contact friction part (1500), a double leather layer with a large surface area absorbs the primary impact, thereby preventing palm pain. The finger contact friction part (1700) contains a material capable of absorbing the impact of three fingers, so it can dampen club vibrations.

[0158] Accordingly, the grip portion (150) can be prevented from twisting upon impact (Anti-Twist), minimizing loss of distance and preventing joint injuries.

[0159] In the next follow-through and finish stage, the club head must be allowed to flow accurately toward the target direction even after impact.

[0160] The palm contact friction part (1500) prevents the glove from rotating until the last moment through continuous internal contact.

[0161] Looking at the finger contact friction part (1700), it is possible to maintain 110% pressure, especially on the little finger of the left hand, so it acts as a final support. As a result, the early release phenomenon caused by an unstable grip is eliminated, and the finish can be completed stably, ensuring consistency of the swing trajectory.

[0162] The specific features of the golf glove (1000) according to the present invention and the golf glove of the prior art are as shown in the following table.

[0163] The results of various tests performed on the golf glove (1000) that has undergone this process (compared to the prior art in some cases) are as shown in the following table. The prior art is a general design in which the finger contact friction part (1700) and the palm contact friction part (1500) are not combined inside the golf glove (1000), and the inner side of the golf glove (1000) is not separately surface-treated.

[0164] Table 1 compares the performance of the golf glove according to the prior art and the present invention.

[0165] Performance metrics Existing gloves The present invention note Slip resistance Standard (100) 223 +123% improvement Grip in rainy conditions 25% level Maintain 92% Driving distance standard +12~15 yards Driver Standards Directionality ±20m deviation ±6m deviation 70% accuracy improvement 18-hole consistency 50% decrease in the second half Maintain 90% in the second half Double the staying power Grip strength compensation 0% 40~50% compensation Overcoming weak grip strength

[0166] According to the results of , it can be seen that the present invention has a significant effect compared to the prior art.

[0167] And when comparing the performance indicators for the case where only the palm contact friction part (1500) according to the prior art and the present invention is applied, the case where only the finger contact friction part (1700) is applied, and the case where both the palm contact friction part (1500) and the finger contact friction part (1700) are applied, they are as shown in below.

[0168] Performance metrics Prior art palm contact friction part (A) Finger contact friction part (B) A + B Slip resistance (overall) 100 (standard) 145 154 223 (Synergy occurs) Maintaining friction in rainy conditions 25% level 63% 65% 92% (Waterproof grip) Driving distance (average) standard +3~4 yards +7~8 yards +12~15 yards Directional (left-right deviation) ±20m ±15m ±10m ±6m (high precision)

[0169] And, as can be seen from , the friction coefficient of the coating layer, in particular, is significantly improved compared to the prior art.

[0170] Environmental conditions Conventional technology (μ) The present invention (μ) Improvement rate dry environment 0.55 0.85 +54% humid environment 0.35 0.75 +114% When sweat occurs 0.30 0.70 +133% Rainy day 0.25 0.65 +160% High temperature and humidity 0.28 0.68 +143%

[0171] In addition, in the case of the present invention, finger contact friction parts (1700) are provided in three finger areas. This is because, as shown in below, excluding any one finger results in a significant difference in the rate of loss of grip force.

[0172] Excluded fingers Loss of grip influence Erythematous on the little finger -33% Risk of leaving the club surging Ring finger solitary -21% Reduced power delivery Little finger and ring finger (on the right side) -54 ~ 67% Power Grip Collapse

[0173] In addition, when comparing the case where a finger contact friction part is applied to one or more fingers with the case where a finger contact friction part (1700) is applied to all three fingers as in the present invention, the relevant indicators are as shown in below.

[0174] division single finger Middle finger + ring finger The present invention Grip coverage 25% 48% 75% Ulna side support imperfection 50% 100% Pressure dispersion effect Localized concentration Partial variance Distributed optimization Reduced finger fatigue 10% 25% 40 ~ 50%

[0175] A golf glove (2000) according to another embodiment of the present invention is characterized by including a formed groin contact friction portion (2100) that contacts the big toe (see 'B' in FIG. 6), as shown in FIG. 7. The groin contact friction portion (2100) may be optionally combined with the preceding embodiments as needed. However, the combined position and size of the groin contact friction portion (2100) are different from the palm contact friction portion (1500), but the remaining characteristics such as material, thickness, and roughness are the same, so a detailed description is omitted below.

[0176] The unexplained reference number '1600' is a seam.

[0177] Accordingly, according to the present invention, a golf glove having a smooth outer surface and an inner palm area and / or finger area can be provided, which prevents twisting or slipping between the palm surface and / or three-finger surface and the golf grip and improves the traction, gripping force, or friction force between the palm surface and three-finger surface and the golf grip.

[0178] In addition, another objective of the present invention is to provide a golf glove with a smooth outer surface and an inner palm area and / or finger area that can improve distance by reducing the loss of power or swing energy on the ulnar side by focusing on the grip of the middle finger, ring finger, and little finger, which account for a large portion of the grip force.

[0179] In addition, another objective of the present invention is to provide a golf glove with a smooth outer surface and an inner palm area and / or finger area that can maintain breathability through micro-perforations and can reliably improve the traction, gripping force, or friction force between the palm surface and three finger surface and the golf grip even in dry conditions or when there is moisture such as rain.

[0180] In addition, another objective of the present invention is to provide a golf glove with a smooth outer surface and an inner palm area and / or finger area, which can maximize efficiency by optimizing both sides of the material portion, which is the glove fabric, to suit different purposes.

[0181] In addition, another objective of the present invention is to provide a golf glove having a smooth outer surface and an inner palm area and / or finger area, which can provide a comfortable fit when worn and improve durability, thereby increasing golf performance and user satisfaction.
