As described herein, the center of gravity (CG) of glof club head 100 can be relatively backward further from face 162, and direction Ground level (for example, 1010 are shown as in Figure 10) is relatively lower, the whole or substantial portion of the second set of weights part 130 with from level Middle plane 1020 is compared closer to bottom 190, and if compared with the second set of weights part 130 is directly coupled to rear portion 166, First and second set of weights parts 120 and 130 are respectively further from rear surface 166.First and second assemble repeated hole 1420 and 1430 The physical attribute and material of the construction of position and the counterweight part in the first and second set of weights parts 120 and 130 can be true It is fixed with most preferably influence the weight of glof club head 100, distribution of weight, center of gravity, moment of inertia characteristic, structural integrity and/ Or other static and or dynamic characteristics.Device described herein, method and manufacture article are without being limited thereto.

Although attached drawing may depict with certain cross sectional with repeated hole, device described herein, method It may include with other suitable cross-sectional shapes with repeated hole with manufacture article.In one example, it first and/or second assembles There can be U-shaped cross-sectional shape 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 cross-sectional shape with repeated hole in hole 1420 and 1430.One associated with the first set of weights part 120 or It is multiple to have with repeated hole different from one or more cross section shapes for matching repeated hole associated with the second set of weights part 130 Shape.For example, there can be U-shaped cross-sectional shape with repeated hole 1421, and there can be V shape cross-sectional shape with repeated hole 1435.In addition, with First set of weights part 120 it is associated two or more with repeated hole can have different cross-sectional shapes.In a similar way, From the second set of weights part 130 it is associated two or more with repeated hole can have different cross-sectional shapes.It is described herein Device, method and manufacture article are without being limited thereto.

It 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 heavy respectively).Alternatively, the first and second set of weights parts 120 and 130 respectively can In quality individually or whole group it is different.Particularly, each counterweight part in first group 120 (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 external counterweight part of glof club head 100 Gross mass be more than 50%.Therefore, glof club head 100 can be configured to make the gross mass of external counterweight part at least 50% is arranged in level below plane 1020.Device described herein, method and manufacture article are without being limited thereto.

In one example, glof club head 100 can be based on golf club model (for example, No. 4 irons dig height throwing Bar) and there is quality of the range at about 220 grams to about 330 grams.Main part 110 can have range at about 200 grams to about 310 Gram quality, the first and second set of weights parts 120 and 130 are respectively provided with about 20 grams of quality (for example, external counterweight part 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 The gross mass for dividing 120 is more than five times so heavy (for example, the gross mass of about 16.8 grams of the second set of weights part 130 is to about 3 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 external 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 external counterweight part of glof club head 100 85%.Device described herein, method and manufacture article are without being limited thereto.

By the way that the first and second set of weights parts 120 and 130 are respectively coupled to main part 110 (for example, by the first He Second set of weights part 120 and 130 is fixed to matching in repeated hole on rear portion 170), position center of gravity (CG) of glof club head 100 Setting can be optimized with moment of inertia (MOI).Particularly, as described herein, the first and second set of weights part 120 and 130 CG can be made to be positioned against the reduction of bottom 190 respectively, and backward further from face 162.In addition, about the vertical of CG is extended past The MOI of axis (for example, perpendicular to ground level 1010) measurement can be bigger.About extending past the trunnion axis of CG (for example, court respectively Extending to the toe and heel 150 and 160 of glof club head 100) MOI of measurement can also be bigger.Therefore, with do not have respectively The glof club head of first and second set of weights parts 120 and 130 is compared, 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 are without being limited thereto.

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

Although counterweight part may be portrayed as individual individual component, the first and second set of weights parts by attached 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 124) can be combined to single-piece counterweight part (for example, first counterweight part).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 Partially (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 individual counterweight parts, without It is three individual counterweight parts shown in the drawings.In another example, the second set of weights part 130 may include five individual Counterweight part, rather than seven individual counterweight parts shown in the drawings.Alternatively, as described above, device described herein, side Method and manufacture article can not include any individual counterweight part (for example, main part 100 can be fabricated to including as main body The quality of the integral part of part 110, independent counterweight part).Device, method and manufacture article described herein are not limited to This.

It is included between front 160 and rear portion 170 and extends back to Fig. 7-9 for example, main part 110 can be hollow body Inner cavity 700.In addition, inner cavity 700 may extend away between top 180 and bottom 190.It inner cavity 700 can be with housing depth 750 (H_C) associated, main part 110 can be with 850 (H of body height_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 based on height 850 at least 50% (H_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 cavity 700 750 be greater 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 strikes 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 are without being limited thereto.

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

In another example, inner cavity 700 can partly or entirely be filled with the polymerization of such as ethylene copolymer materials etc Object material, to be impacted in glof club head 100 by being absorbed when 162 impact golf of face, isolation vibration and/or inhibition Noise.Particularly, at least 50% inner cavity 700 can be filled with high density ethylene copolymers ionomers, fatty acid modified ethylene Copolymers ionomers, Gao Feijing ethylene copolymer ionomers, hexenoic acid acrylate terpolymer ionomer including magnesium The ethylene copolymer of ionomer can be used in conventional injection molding equipment being total to the ethylene for manufacturing injection moldable of various shapes Polymers can be used for conventional extruded equipment to manufacture ethylene copolymer of various shapes, and/or be similar to thermosetting property polybutadiene rubber The ethylene copolymer with high compression and low rebound of glue.For example, ethylene copolymer may include and by the Delaware State The DuPont of the E.I.du Pont de Nemours and Company manufacture of Wilmington^TMHigh performance resin (HPF) system The material of column 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 It is molding, and can be used together with conventional injection molding equipment and mold, low pressure contracting is provided, and provide high rebound.Here The device of description, method and manufacture article are without being limited thereto.
