Although accompanying drawing may depict matches somebody with somebody repeated hole, device described herein, method with certain cross sectional It may include to match somebody with somebody repeated hole with other suitable shape of cross sections with manufacture article.In one example, first and/or second assemble There can be U-shaped shape of cross section with repeated hole in repeated hole 1420 and 1430.In another example, the first and/or second set of weights There can be V shape shape of cross sections with repeated hole in hole 1420 and 1430.Associated with the first set of weights part 120 one or It is multiple to have different from the one or more cross section shapes with repeated hole associated with the second set of weights part 130 with repeated hole Shape.For example, there can be U-shaped shape of cross section with repeated hole 1421, and there can be V shape shape of cross sections with repeated hole 1435.In addition, with Associated two or more in first set of weights part 120 can have different shape of cross sections with repeated hole.In a similar way, Different shape of cross sections can be had by matching somebody with somebody repeated hole from two or more that the second set of weights part 130 is associated.It is described herein Device, method and manufacture article not limited to this.

First and second set of weights parts 120 and 130 respectively can be similar in quality (for example, first and second group of 120 He All counterweight parts in 130 are about equally weighed respectively).Alternatively, the first and second set of weights parts 120 and 130 respectively can In quality individually or whole group it is different.Especially, in first group 120 each counterweight part (for example, be shown as 121,122, 123 and 124) can have than any counterweight part in second group 130 (for example, being shown as 131,132,133,134,135,136 With 137) relatively smaller quality.For example, the second set of weights part 130 can account for the outside counterweight part of glof club head 100 Gross mass more than 50%.Therefore, glof club head 100, which can be configured to, makes the gross mass of outside counterweight part at least 50% is arranged on the lower section of plane 1020 in level.Device described herein, method and manufacture article not limited to this.

In one example, glof club head 100 can be based on golf clubs model (for example, No. 4 irons are dug to height throwing Bar) and with quality of the scope at about 220 grams to about 330 grams.Main part 110 can have scope to arrive about 310 at about 200 grams Gram quality, the first and second set of weights parts 120 and 130 have about 20 grams of quality (for example, outside counterweight part respectively Gross mass).Each counterweight part in first group 120 may have about the quality of 1 gram (1.0g), and in second group 130 Each counterweight part may have about 2.4 grams of quality.The quality sum of first set of weights part 120 can be about 3 grams, and second The quality sum of set of weights part 130 can be about 16.8 grams.The gross mass of second set of weights part 130 can be the first set of weights portion Points 120 gross mass is so weighed (for example, the gross mass of about 16.8 grams of the second set of weights part 130 is to about 3 more than five times Gram the first set of weights part 120 gross mass).Glof club head 100 can have respectively from the first and second set of weights 19.8 grams of gross mass of part 120 and 130 is (for example, 3 grams and the second set of weights part 130 of the first set of weights part 120 16.8 grams of summation).Therefore, the first set of weights part 120 can account for the total of the outside counterweight part of glof club head 100 About the 15% of quality, and the second set of weights part 130 can account for the pact of the gross mass of the outside counterweight part of glof club head 100 85%.Device described herein, method and manufacture article not limited to this.

By the way that the first and second set of weights parts 120 and 130 are respectively coupled into main part 110 (for example, by the first He Second set of weights part 120 and 130 is fixed to matching somebody with somebody in repeated hole on rear portion 170), center of gravity (CG) position of glof club head 100 Putting can be optimized with moment of inertia (MOI).Especially, as described herein, the first and second set of weights part 120 and 130 CG can be made to be positioned against bottom 190 respectively to be reduced, and backward further from face 162.In addition, on extending past the vertical of CG The MOI of axle (for example, perpendicular to ground level 1010) measurement can be bigger.On extending past CG trunnion axis (for example, court respectively To glof club head 100 toe and heel 150 and 160 extend) measurement MOI also can be bigger.Therefore, with not having respectively First and second set of weights parts 120 are compared with 130 glof club head, and club head 100 can provide relatively bigger transmitting Angle (launch angle) and the relatively smaller speed of rotation.Device described herein, method and manufacture article not limited to this.

Alternatively, two or more counterweight parts in same group can be different in quality.In one example, first group 120 counterweight part 121 can have the relatively smaller quality of the counterweight part 122 than first group 120.In another example, Two group 130 of counterweight part 131 can have the relatively smaller quality of the counterweight part 135 than second group 130.In top-toe When having larger quality at transitional region and/or bottom-toe transitional region, more weight can be distributed away from glof club head 100 center of gravity (CG), so as to improve the moment of inertia (MOI) around the vertical axis by CG.

Although counterweight part may be depicted as single individual component, the first and second set of weights parts by accompanying drawing Every group in 120 and 130 can be single-piece counterweight part respectively.In one example, first group 120 of whole counterweight part (examples Such as, 121,122,123 are shown as and single-piece counterweight part (for example, first counterweight part) 124) is can be combined to.In a similar way, Second group 130 of whole counterweight parts (for example, 131,132,133,134,135,136 and 137) are also combined into single-piece counterweight Partly (for example, second counterweight part).In this example, glof club head 100 can have only two counterweight parts.Although attached Figure may depict certain amount of counterweight part, but device described herein, method and manufacture article may include it is more or Lesser amount of counterweight part.In one example, the first set of weights part 120 may include two single counterweight parts, without It is three shown in the drawings single counterweight parts.In another example, the second set of weights part 130 may include five individually Counterweight part, rather than seven shown in the drawings single counterweight parts.Alternatively, as described above, device described herein, side Method and manufacture article can not include any single counterweight part (for example, main part 100 can be fabricated to including as main body The quality of integral part, the independent counterweight part of part 110).Device described herein, method and manufacture article are not limited to This.

Fig. 7-9 are returned to, for example, main part 110 can be hollow body, is included between front portion 160 and rear portion 170 and extends Inner chamber 700.In addition, inner chamber 700 may extend away between top 180 and bottom 190.Inner chamber 700 can be with housing depth 750 (H_C) associated, main part 110 can be with (the H of body height 850_B) associated.Although the chamber between toe and heel 140 and 150 Body height 750 and body height 850 can change, but housing depth 750 can be at least 50% (H of body height 850_C >0.5*H_B).For example, housing depth 750 can change between the 70%-85% of body height 850.The housing depth of inner chamber 700 750 be more than body height 850 50% when, with housing depth be less than body height 50% glof club head compared with, When glof club head 100 impacts golf by face 162, glof club head 100 can produce relatively more consistent sense Feel, sound and/or result.Device described herein, method and manufacture article not limited to this.

In one example, inner chamber 700 can be not filled in (for example, empty space).Main part 100 with inner chamber 700 It is light about 100 grams than the main part 100 without inner chamber 700.Alternatively, inner chamber 700 can partly or entirely be filled with bullet Property polymer or elastomeric material (for example, such as by Ohio Kent Sorbothane companies manufacture The viscoplasticity urethane polymers material of material etc), thermoplastic elastomer (TPE), thermoplastic polyurethane material (TPU) and/or other suitable types material to absorb impact, isolation vibrations and/or suppress noise.For example, at least 50% Inner chamber 700 can filled with TPE material with glof club head 100 by face 162 impact golf when absorb impact, Isolation vibrations and/or suppression noise.

In another example, inner chamber 700 can partly or entirely be filled with the polymerization of such as ethylene copolymer materials etc Thing material, is impacted with being absorbed when glof club head 100 impacts golf by face 162, is isolated vibrations and/or is suppressed Noise.Especially, at least 50% inner chamber 700 can be filled with high density ethylene copolymers ionomers, fatty acid modified ethene Copolymers ionomers, high amorphous ethylene copolymer ionomers, the ionomer including magnesium of the terpolymer of hexenoic acid acrylate The ethylene copolymer of ionomer, available in conventional injection molding equipment with manufacture variously-shaped injection moldable ethene be total to Polymers, available for conventional extruded equipment to manufacture variously-shaped ethylene copolymer, and/or similar to thermosetting polybutadiene rubber The ethylene copolymer with high compression and low resilience of glue.For example, ethylene copolymer may include and by the Delaware State The DuPont of Wilmington E.I.du Pont de Nemours and Company manufactures^TMHigh performance resin (HPF) system The material of row is (for example, DuPont^TM HPF AD1172、 DuPont^TM HPF AD1035、HPF 1000 and DuPont^TMHPF 2000) associated any ethylene copolymer.DuPont^TMThe ethylene copolymer of HPF series is injectable Shaping, and can be used together with conventional injection molding equipment and mold there is provided low pressure contracting, and high resilience is provided.Here Device, method and the manufacture article not limited to this of description.
