Can be configured to present one or more optimization characteristics according to glof club head of the present disclosure, the performance of described optimization characteristics optimization or balance golf club.Such as, the design attempts the characteristic that a characteristic of the glof club head optimized is face height and/or working face size.The face height of glof club head and/or working face size are maximized and can have some beneficial effects, such as increase the target impact area of impact surface, to relax the requirement to bar head, thus better result is produced for the golf driving departing from impact surface central point.In addition, once impact surface and golf ball impact, energy can be passed to golf by larger impact surface height and/or size better, and therefore can increase characteristic time or " spring " of glof club head, to realize more long range golf driving.In some instances, height or the size of impact surface can be increased, to reach the characteristic time restriction set by golf management organization, the characteristic time restriction of 239 microseconds (μ s) such as set in its flexible specification by USGA.

But, increase face height and/or size may bring adverse effect to performance in other respects indiscriminately, after golf and impact surface clash into, such as affect the angle of departure of golf, ball rotates and/or ball speed.Such as, increase face height and/or size can reduce the CG degree of depth between the center of gravity of glof club head and impact surface central point, to cause center of gravity to move forward, thus reduce the dynamic loft of glof club head, and reduce the angle of departure of golf thus.As shown in another example, increase face height and/or size can improve the CG height between center of gravity and bar head depth plane, make it away from the bottom of glof club head to promote center of gravity, thus prevent the gear effect between impact surface and golf, prevent glof club head from reducing the convolution amount of the golf produced after impact thus, and therefore reduce the ball distance of will advance due to convolution.

Consider the above, the height of the working face of glof club head or size should with the position balance of center of gravity.About glof club head 1000, impact surface 1210 has been increased to the working face size and/or face height 1213 that comprise increase, to provide larger impact area and by more energy transferring to golf 2900.Particularly, glof club head 1000 can be configured to make face height 1213 to be about 33mm to about 71mm, to provide larger impact area and transmit more energy after clashing into golf 2900.In some instances, the area comprising the face area of increase of impact surface 1210 can be about 23.6 square centimeters of (cm ²) to about 45.2cm ².

Although increased above-mentioned working face size and/or face height 1213, glof club head 1000 still limits CG height 2520 have been increased and/or partially too far away from bar head depth plane 2310 towards bar head top section 1120.Such as, glof club head 1000 comprises the first optimization characteristics meeting following relation 1:

| CG height ₂₅₂₀|≤5.08mm [relation 1]

Can there is such example, wherein, CG height 2520 can be about 0 millimeter of limit to the 5.08mm of relation l.In other examples, CG height 2520 can also reach the maximum of about 4.45mm, 3.81mm or 3.18mm.In certain embodiments, the first optimization characteristics reduce the convolution of golf 2900 by the gear effect between impact surface 1210 and golf 2900, to reach better performance.Although bar is nose heave, the heart 2500 is shown in Figure 2 for and is positioned under depth plane 2310, extend between 1130 bottom depth plane 2310 and bar head to make CG height 2520, but such embodiment can be there is, wherein, bar is nose heave, and the heart 2500 can be positioned on depth plane 2310, to make CG height 2520 extend between depth plane 2310 and bar crown portion 1120, still meet with co-relation 1 simultaneously.

In addition, consider working face size and/or the face height 1213 of above-mentioned increase, glof club head 1000 still limits center of gravity 2500 and moves towards impact surface 1212, thus prevents the CG degree of depth 2510 from excessively reducing.Such as, glof club head 1000 comprises the second optimization characteristics meeting following relation 2:

[relation 2]

Therefore, the relation between face height 1213 and the CG degree of depth 2510 balances according to relation 2, to keep the second optimization characteristics being less than or equal to 0.56, thus the amount that the restriction CG degree of depth 2510 can reduce towards impact surface 1210.Can there is such example, wherein, the CG degree of depth 2510 can be about 25mm to about 102mm.In identical or other examples, the CG degree of depth 2510 can be at least about 39mm.In certain embodiments, after the second optimization characteristics can be clashed between glof club head 1000 and golf 2900, increase or optimize at least one in the dynamic loft of glof club head 1000 or the angle of departure of golf 2900.

In some instances, glof club head 1000 can be configured to only include in the above-mentioned first or second optimization characteristics.Such as, glof club head 1000 can comprise the first optimization characteristics and not comprise the second optimization characteristics, therefore meets relation 1 and need not meet relation 2.As shown in another example, glof club head 1000 can comprise the second optimization characteristics and not comprise the first optimization characteristics, therefore meets relation 2 and need not meet relation 1.In addition, can there is such embodiment, wherein, glof club head 1000 meets both relation 1 and relation 2, and therefore comprises the first and second optimization characteristics.

Glof club head 1000 also can comprise the 3rd optimization characteristics relative to long-pending (HV) 2600 of the rod head body of glof club head 1000.In this example, the bar head main body 1000 of glof club head 1000 comprises type main body of kicking off, the type main body of kicking off has the rod head body being more than or equal to 420 cubic centimetres (cc) and amasss, and therefore bar head main body 1000 has the rod head body product value being more than or equal to 420.Such as, the rod head body that bar head main body 1000 can comprise 420cc amasss, and therefore has the rod head body product value of 420.As shown in another example, the rod head body that glof club head 1000 can comprise 460cc amasss, and therefore has the rod head body product value of 460.The rod head body that glof club head 1000 can comprise up to about 470cc amasss, and in certain embodiments, and/or can comprise the nose heave amount of total bar of about 185 grams to about 225 grams.In some particular example, amount that total bar is nose heave can be about 202 grams, and/or rod head body long-pending can be about 460cc.

[relation 3]

In some cases, rod head body long-pending 2600 can be increased, to adjust the rotary inertia (MOI) of such as glof club head 1000.But unconfined increase rod head body amasss can have adverse effect to other characteristics of glof club head.Such as, increasing rod head body long-pending 2600 can cause the nose heave heart of bar 2500 towards bar head front portion 1110, towards bar crown portion 1120, towards other less desirable direction transfers, and/or away from desired position of centre of gravity or direction, thus hinder the performance of glof club head 1000.These less desirable changes of position of centre of gravity can have a negative impact to one or more characteristics of glof club head, and described characteristic is emission rate, the angle of departure, gear effect, convolution and/or transmitting range such as.Therefore, the 3rd optimization characteristics for the relation between balancing pole head volume 2600 and the position of the nose heave heart 2500 of bar can be set up, with produce for glof club head 1000 expectation with balance attribute.Such as, the distribution of weight of glof club head 1000 can be configured to meet relation 3, the 3rd optimization characteristics can be presented to make glof club head 1000, thus allow to increase rod head body long-pending 2600, after the golf ball between impact surface 1210 and golf 2900, obtain larger rotary inertia and by more energy transferring to golf 2900.In identical or other embodiments, the distribution of weight of glof club head 1000 can be configured to reduce towards bar head anterior 1110 due to the rod head body long-pending 2600 increased for limiting the CG degree of depth 2510, thus after golf ball, increase at least one in the dynamic loft of impact surface 1210 or the angle of departure of golf 2900.In addition, the distribution of weight of glof club head 1000 can be configured to increase towards bar crown portion 1120 due to the rod head body long-pending 2600 increased for limiting CG height 2520, thus after golf ball, reduced the convolution of golf 2900 by the gear effect between impact surface 1210 and golf 2900.

Consider the above, in order to obtain the 3rd optimization characteristics of the relation of meeting 3, the CG degree of depth 2510 can be configured to be more than or equal to 40.64mm.In identical or other embodiments, the absolute value of CG height 2520 can be less than or equal to 2.54mm.It should be noted, consider in some embodiments, bar is nose heave, and the heart 2500 can on or below bar head depth plane 2310, and the feature of CG height 2520 is absolute values.Although the 3rd optimization characteristics have the lower limit of at least 425, other embodiments that the 3rd optimization characteristics can define according to other lower limits can be there are.Such as, in certain embodiments, the 3rd optimization characteristics can comprise the lower limit of at least 435 or 445.The position of bar the is nose heave heart 2500 can also carry out designing or configuring according to other features of glof club head 1000, to meet relation 3 and/or to obtain the 3rd optimization characteristics.Such as, the position of bar the is nose heave heart 2500 can be configured to make the CG degree of depth 2510 be included in about 25% of bar head profound 2312 to about between 80%, wherein, bar head profound 2312 is measured from the intersection point that the outside of impact surface central point 1211 to bar back of head part 2160 is crossing with bar head depth plane 2310.As shown in another example, the position of bar the is nose heave heart 2500 can be configured to make CG height 2520 be included in about 0% of CG altitude axis length 2322 to about between 13%, wherein, the intersection point that CG altitude axis length 2322 is crossing with CG altitude axis 2320 from the outside in bar crown portion 1120 to bar head 1130 outside and the intersection point that intersects of CG altitude axis 2320 measure.

Glof club head 1000 also can comprise the 4th optimization characteristics, and the 4th optimization characteristics are corresponding with the equilibrium phase between hosel MOI1711 (Fig. 1) with horizontal MOI1811 (Fig. 1).Hosel MOI1711 is defined as around hosel axle 1710.Horizontal MOI1811 is defined as around bar head trunnion axis 1810, bar head trunnion axis 1810 extends through the nose heave heart 2500 of bar from bar head heel 1140 to bar head toe 1150, and is parallel to ground level 1010 when being positioned at the address position place on ground level 1010 when glof club head 1000.
