Description

[Technical Field] 【0001】 <Related applications> This application claims priority under § 119(e) of the United States Patent Act with respect to U.S. Provisional Application No. 63 / 470,687 and U.S. Provisional Application No. 63 / 470,674, filed on June 2, 2023, the contents of which are incorporated herein by reference. 【0002】 This disclosure relates primarily to the field of golf club heads, and more specifically to iron, driver, fairway wood, and / or hybrid golf club heads having a face insert made of a different material from the rest of the golf club head, and / or perimeter weighting. [Background technology] 【0003】 Despite recent technological advancements in golf equipment, golf remains a difficult sport to play at an expert level. For a golf ball to fly reliably along a desired trajectory and in a desired direction, the clubface must strike the ball while aligned with the desired clubface path. Furthermore, for a golf ball to fly reliably along a desired trajectory, in a desired direction, and for a desired distance, the clubface must strike the ball at or near the desired position on the clubhead face. Off-center hits tend to "twist" the clubface upon contact with the ball, which can cause the ball to fly in an unintended direction, impart unintended hook or slice spin, and / or reduce the distance of the shot. If the contact between the clubface and the ball deviates from the desired contact point and / or is located away from the desired ball contact point on the clubface, even by a relatively minor amount, it can cause the golf ball to be launched in the wrong direction, often accompanied by unintended hook or slice spin, and / or reduce the distance of the shot. The distance and direction of a golf ball's flight can also be greatly influenced by the spin imparted to the ball upon impact with the clubhead. Various golf clubheads have been designed to improve golfers' accuracy by assisting them in keeping the clubface square at impact with the golf ball. 【0004】 The golf club head of this disclosure is provided to address the aforementioned and other problems, and to provide advantages and aspects not provided by conventional ball striking devices of this kind. A detailed description of the features and advantages of the present invention is provided below with reference to the accompanying drawings.

[Modes for carrying out the invention] 【0036】 The following description is merely illustrative and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides a convenient illustration for carrying out exemplary embodiments of the invention. Various modifications can be made to the function and configuration of the elements of the embodiments described herein without departing from the scope of the invention as set forth in the appended claims. 【0037】 Referring to the attached drawings, particularly Figures 1-2, a golf club head 10 configured according to this disclosure comprises a body 12, a strike face plate 14, a hosel 16, a leading edge 18, a top line 20, and a sole 22. Preferably, the body 12 has a mating cavity or recess 11 formed on its front surface 13. The strike face plate 14 and the mating cavity may preferably be trapezoidal, as shown in Figure 1. In various applications, the strike face plate 14 and the mating cavity 11 can have various shapes, such as rectangular, swallowtail, dovetail, hexagonal, elliptical, irregular, or other shapes. The mating cavity 11 preferably has means for holding the strike face plate 14 within the mating cavity 11. Preferably, the strike face plate 14 is joined to the body 12 within the mating cavity 11 using nickel paste or silver paste in a vacuum brazing process. Preferably, the strike faceplate 14 may define areas of bulge, roll, and / or varying face thickness. 【0038】 Preferably, the strike faceplate 14 is made from zirconia, also known as zirconium dioxide (ZrO2), for example. Zircon is a mineral that is a byproduct of the mining and processing of ancient heavy mineral placer deposits. It is also called zirconium silicate and has the chemical composition ZrSiO4. Zirconia can be produced by melting zircon in an electric arc furnace at very high temperatures, usually exceeding 2,600°C, to form molten zirconia, also known as zirconium oxide (ZrO2). Zirconium is another derivative of zircon, the chemical element Zr in the periodic table, and takes the form of a silvery-gray metal. It is usually produced by reducing the chemical zirconium oxychloride (ZOC), which itself is produced by the complex process of chemical dissociation of zircon (zirconium silicate). Preferably, the strike face plate 14 is made of acrylic resin mixed with zirconia powder to form the desired shape of the strike face plate 14, and may or may not include bulges and / or rolls (bulges are the curvature of the clubface from heel to toe, and rolls are the curvature of the face from the crown to the sole of the club). The unfired strike face plate 14 is then sintered in a furnace at a temperature of 1200°C ± 50°C, and the resin is burned off, leaving a strike face plate 14 that is nearly 100 percent zirconia. 【0039】 In a preferred embodiment, the body 12 of the golf club head 10 is formed from a metal (e.g., steel), a metal alloy (e.g., titanium alloy, aluminum alloy, and / or magnesium alloy), a composite material such as a graphite composite, a ceramic material, or any combination thereof. In a particular preferred example, the golf club head 10 includes a body 12 formed mainly from steel and a strike face plate 14 formed mainly from zirconia (zirconium dioxide). The zirconia (zirconium dioxide) material used for the strike face plate 14 preferably has a hardness in the range of HV 1,100 to 1,300. Such a material for the strike face plate 14 provides an extremely hard striking surface with a hardness close to that of sapphire, which is second only to diamond in hardness. This results in increased ball compression, much higher launch velocities, and greater distance in golf clubs, including drivers, fairway woods / metals, utility clubs and hybrid clubs that incorporate elements of both woods and irons to emphasize the better characteristics of each, and irons, especially long irons. 【0040】 Figures 3-6 show further preferred embodiments of a golf club head 30 constructed in accordance with the present disclosure, which includes a body 32, a strike face plate 34, a hosel 36, a leading edge 37, a topline 38, and a sole 39. Preferably, a fitting cavity or recess 31, for example in a trapezoidal shape, is formed on the front face 33 of the body 32. In various applications, the fitting cavity 31 can be in a rectangular,燕尾形, tongue-and-groove, or other various shapes. The fitting cavity 31 preferably has means for holding the strike face plate 34 within the fitting cavity 31. Further, the peripheral edge 40 of the body 32 around the strike face plate 34 is preferably machined away, removed by other means, or originally formed together with the body 32. Alternatively, the peripheral edge 40 includes a peripheral material 41 having a higher density than the material constituting the body 32, stabilizing the golf club head 30 upon impact of any type of golf ball, enhancing the power, accuracy, and forgiveness during an off-center hit, and at the same time producing a higher trajectory. The density of the material that can be used in the club head 30 is 7,850 kg / m 3 for mild steel, 7,982 kg / m 3 for stainless steel, 4,520 kg / m 3 for titanium, 19,450 kg / m 3 for tungsten, and tungsten alloys in a density range of about 15,000 kg / m 3 to about 22,000 kg / m 3 . 【0041】 It should be noted that the "燕尾形" in the original text is not a recognized English term. You may need to check the specific shape name in the original language to ensure the accuracy of the translation. If it is a special or misspelled term, it may be necessary to correct it according to the actual situation. Here, it is directly translated as "燕尾形" for the purpose of showing the translation process.Alternatively, as shown in Figures 5 and 7, the high-density material 41 of the periphery 40 may be inserted into the body 12 along the periphery 40, preferably inside the strike face plate 34, where it is not visible, or it may be attached to the outer surface of the front 33 around the strike face plate 34 to provide a distinctive appearance to the golf club head 30. In any embodiment of the golf club head 30, the high-density material 41 of the periphery 40 may extend continuously, intermittently, or partially outside or inside the front 33 of the club head 30, around or behind the strike face plate 34. Furthermore, the high-density material 41 of the periphery 40 may consist of circular, triangular, or square rods, or a sintered metal powder material containing one or more of tungsten, tungsten alloys, and other high-density materials. Again, the strike face plate 34 is preferably formed primarily from zirconia (zirconium dioxide). Furthermore, the zirconia (zirconium dioxide) material used in the strike faceplate 34 preferably has a hardness in the range of HV 1,100 to 1,300. 【0042】 A golf club head 30 having a peripheral edge 40 made of high-density material 41 is particularly suitable for golf club irons, especially long irons. 【0043】 As shown in Figures 8 and 11, the golf club head 10 preferably comprises a body 12, typically made of steel or titanium, and a strike face plate 14, the strike face plate 14 being housed in a graphite cartridge 50 before the cartridge 50 is attached to the body 12, preferably using a resin such as acrylic resin. In this embodiment, as shown in Figure 8, substantially the entire front surface 13 of the club head 10 includes the graphite cartridge 50 surrounding the strike face plate 14. In this preferred embodiment, the strike face plate 14 is preferably formed primarily from zirconia (zirconium dioxide). The zirconia (zirconium dioxide) material used for the strike face plate 34 preferably has a hardness in the range of HV 1,100 to 1,300. 【0044】 Figures 9-10 show another preferred embodiment of a golf club head 10, which preferably comprises a body 12 made typically of steel or titanium and a strike face plate 14 set in a mating cavity 11 using components 52 of graphite and resin (such as acrylic resin). In this preferred embodiment, the strike face plate 14 is preferably formed primarily of zirconia (zirconium dioxide). The zirconia (zirconium dioxide) material used for the strike face plate 34 preferably has a hardness in the range of HV 1,100 to 1,300. 【0045】 In a preferred embodiment, the body 32 of the golf club head 30 is formed from a metal (e.g., steel), a metal alloy (e.g., steel alloy, titanium alloy, aluminum alloy, and / or magnesium alloy), a composite material such as a graphite composite, a ceramic material, or any combination thereof. In a particular preferred example, the golf club head 30 includes a body 32 formed mainly from a steel or titanium alloy, a peripheral member 41 made mainly from tungsten, and a strike face plate 34 formed mainly from zirconia (zirconium dioxide). 【0046】 Referring to Figures 12-14, the golf club head 10 is equipped with a weight band 70, which is preferably located on or inside the body 12, or integrally formed with the body 12 by 3D printing or the like. As shown in Figures 12-13, the weight band 70 preferably extends around the outer circumference of the body 12 in a plane parallel or substantially parallel to the strike face plate 14. The weight band 70 preferably contains a material 71 that is denser than the material constituting the body 12, stabilizing the golf club head 10 upon impact with any type of golf ball, increasing power, accuracy, and forgiveness on off-center hits, while also producing a higher trajectory. The density of the material usable in the club head 10 is 7,850 kg / m³ for mild steel. 3 Stainless steel 7,982 kg / m 3 Titanium 4,520 kg / m 3 , Tungsten 19,450 kg / m 3 , and approximately 15,000 kg / m 3 From approximately 22,000 kg / m 3 It is a tungsten alloy in the density range. 【0047】 Alternatively, as shown in Figure 15, the high-density material 71 of the weight band 70 may preferably be inserted into the body 12 so as not to be visible, or placed on the surfaces of the crown 24 and sole 22 to provide a distinctive appearance to the golf club head 10. In any embodiment of the golf club head 10, the high-density material 71 of the weight band 70 may extend continuously, intermittently, or partially along the periphery of the body 12. Furthermore, the high-density material 71 of the weight band 70 may include circular, triangular, or square rods, or sintered metal powder material. 【0048】 A golf club head 10 having a high-density material 71 of a weight band 70 positioned in a plane parallel or substantially parallel to the strike face plate 14 is particularly suitable for golf club drivers, fairway woods, utility clubs, and hybrids. 【0049】 In a preferred embodiment, the body 12 of the golf club head 10 is formed from a metal (e.g., steel), a metal alloy (e.g., titanium alloy, aluminum alloy, and / or magnesium alloy), a composite material such as a graphite composite, a ceramic material, or any combination thereof. 【0050】 In one specific example, the golf club head 10 includes a body 12 made of titanium alloy, a weight band 70 containing a material 71 made of tungsten or a tungsten alloy, and a strike face plate 14 made of zirconia (zirconium dioxide). Preferably, the body 12 has a weight of approximately 7,500 kg / m 3 ~Approx. 8,000kg / m 3 The peripheral portion 40 and / or weight band 70, which include the first material having a density of 71, have a density of approximately 15,000 kg / m 3 ~Approx. 22,000kg / m 3 It includes a second material having a density of . 【0051】 The figures in this specification show a golf driver or iron club head, but the golf club heads in this disclosure may further include fairway woods, hybrids, wedges, or putters. 【0052】 It will be understood that each of the above elements, or two or more elements combined, may find useful applications in ways different from those described above. 【0053】 While certain novel features of the present invention are illustrated, described, and pointed out in the appended claims, they are not intended to be limited to the above-mentioned details.
