In the current embodiment of club head 100, the center of gravity 211 of club head 100 positions towards the heel 113 of body 110, and is shifted away from toe 217 by protrusion weights 221.In the present embodiment, toe 217 from geometric center 212 towards toe to extension, and heel 113 from geometric center 212 towards with to extension.In the present embodiment, protrusion weights 120 by the center of gravity 211 of club head 100 towards heel 113, shift towards bottom 110 with towards rear portion 114.In identical or different embodiment, the center of gravity 211 of club head 100 can be shifted about 1.25mm to about 5.1mm towards heel 113 by protrusion weights 120, and/or shifts about 7.6mm to about 12.7mm towards rear portion 114.In identical or different embodiment, the center of gravity 211 of club head 100 can be shifted by the protrusion weights 120 center of gravity away from body 110 and/or the geometric center 212 away from body 110.Can embodiments exist that, wherein geometric center 212 can include the cubing center of body 110 and/or consistent with the cubing center of body 110.In another embodiment including Fairway Woods head, the center of gravity of Fairway Woods head can be shifted about 1.6mm to about 2.0mm towards the heel of Fairway Woods head by the protrusion weights being similar to protrusion weights 120, and/or shifts about 1.4mm to about 1.7mm towards the rear portion of Fairway Woods head.
As will be described further, protrusion weights 221 transfer of the center of gravity 211 of the club head 100 caused can provide the some benefits swung improving user, is corrected as contributed to hitting user Slice tendency.In the present embodiment, club head 100 does not has toe weight member at toe 217, and wherein, the transfer of the center of gravity 211 caused because of protrusion weights 120 can be offset by above-mentioned toe weight member.
Additionally, from Fig. 1-8 it can be seen that as from as the homing position view shown in Fig. 6, protrusion weights 120 is from the outside of club head 100.This layout about observability can have additional benefit, i.e. for may realize that the outside of protrusion weights 120 arranges the control of available enhancing and the user raising user confidence of performance characteristics.The layout of present embodiment also allows for protrusion weights and is formed, thus changes whole outward appearance and/or the structure of club head 100 compared with same category of conventional club head indistinctively.As embodiment, bulk volume 812 can be considered the heel volume being separated into towards heel 113 and the toe volume towards toe 217, wherein, heel volume can be configured to differ each other within about 20% with toe volume, to keep symmetrical and therefore maintain club head 100 relative to conventional club head whole outward appearance and structure.In identical or other embodiment, heel volume and toe volume can be configured to differ each other within about 10%.In certain embodiments, conventional club head can pyriform, triangle, C-shaped and/or square symmetrically, even if these shapes have additive and also can substantially maintain.Therefore, the bulk volume 812 of club head 100 and/or sidewall 118 need not significantly change into shape the best in the worst and/or structure that may adversely affect ball emission rate or ballistic characteristics, thus realize the center of gravity metastasis degree that protrusion weights 120 is allowed in the present embodiment for center of gravity 211.
Here for being easy to explanation, as it is shown in figure 5, around geometric center 212 club head 100 can be further divided into 4 quadrants, i.e. before-with quadrant 551, front-toe quadrant 552, rear-with quadrant 553 and rear-toe quadrant 554.In this arrangement, as it is shown in figure 5, the center of gravity 221 of protrusion weights 120 can be located at after-with quadrant 553 at, even if a part for protrusion weights 120 extends in other quadrant one or more.In addition, as can be seen from Figure 6, club head 100 can be referred to as compass basal plane (compassplane) 580, compass basal plane 580 centers about the geometric center 212 of body 110 and is limited by with-toe axis 581 and anterior-posterior axis 582, wherein, with the toe-end of-toe axis 581 is positioned at 0 degree, and the homing position visual angle that the angle of wherein compass basal plane 580 is relative to Fig. 6 increases in clockwise manner so that 90 scale designations of compass basal plane 580 are positioned at the rear end of anterior-posterior axis 582.In the current embodiment of club head 100, with reference to the homing position shown in Fig. 6, between the center of gravity 221 of protrusion weights 120 can be positioned on relative to about 120 degree to about 180 degree of compass basal plane 580.More specifically, center of gravity 221 can be positioned on about 135 degree relative to compass basal plane 580, but other position is also likely to be suitably in other embodiments.
But, according to intended club head effect or characteristic, also can there is such embodiment, wherein center of gravity 221 can be positioned on except in Fig. 5 rear-with quadrant 553 in addition to other quadrant at or quadrant between, and/or be positioned between other angle or the angular range in addition to the scope above in regard to about 120 degree to about 180 degree described in compass basal plane 580.
In the present embodiment, protrusion weights 120 front-with quadrant 551 at separate with hosel portion 116, thus after the position of the center of gravity 221 of protrusion weights 120 is maintained at-with quadrant 553.Such as make the center of gravity 211 of club head 100 keep with the front portion 115 of body 110 away from for, this position separated with hosel portion 116 is probably useful.In identical or different embodiment, achieved by protrusion weights 120 and center of gravity 211 towards rear portion 114 and/or is kept towards bottom 111 or shifts, so can allow the service characteristic improved.The emission characteristics of this improvement can include that the higher angle of departure and/or relatively low transmitting rotate, and this may cause producing more excellent trajectory and farther distance when club head 100 clashes into golf.Figure 13 illustrates the comparison of flight path 13100 and flight path 13200, and wherein, flight path 13100 includes that the emission characteristics improved, the highest angle of departure and relatively low transmitting rotate, and flight path 13200 includes that the relatively low angle of departure and higher transmitting rotate.
In the present embodiment, counterweight 210 is also set up the center of gravity 211 of club head 100 to be shifted towards heel 113 and towards rear portion 114.As seen in the exemplary cases of Figure 10-11, for the gear effect that impact causes because of the shock between face 215 and golf 1050, this configuration is probably useful.Figure 10 illustrates between ball 1050 and face 215 and towards the image of club head 100 during toe 217 generation shock.Figure 11 illustrates between ball 1050 and face 215 and towards the image of club head 100 during heel 113 generation shock.
With reference to shown in Figure 10, protrusion weights 120 is configured, thus when face 215 is at rum point 1040 and when clashing into towards toe 217 with ball 1050, and this protrusion weights 120 passes to increase left-handed 1011 on ball 1050.In the present embodiment, shifting towards heel 113 owing to being extended the center of gravity 211 of 252 acquisition club head 100 by the distance above by reference to described in Fig. 2 and Fig. 9, therefore the distance 1020 between center of gravity 211 and rum point 1040 increases.When club head 100 is clashed into ball 1050 at rum point 1040 and is carried out rotating 1012 around center of gravity 211, this increase of distance 1020 can produce the gear effect 1010 of enhancing between face 215 and ball 1050, if be therefore positioned at protrusion weights 120 bulk volume 812 (Fig. 8) internal and issuable left-handed compared with, left-handed 1011 that this increase of distance 1020 can will be further increased are passed on ball 1050.In identical or different embodiment, owing to the center of gravity 211 of club head 100 is positioned at heel 113, even if therefore rum point 1040 is positioned at the center of face 215, left-handed the 1010 of increase still can be transferred on ball 1050.
