In another aspect of the present invention, golf clubs 100 can use chucking appliance system to carry out physical orientation in reference position.As mentioned above, the axis 106a (and/or hosel axis) of shaft can aim at the bar base angle of the description according to golf clubs manufacturer or with the suitable bar base angle such as determined by those skilled in the art.Golf club head 102 can be placed with its basal surface 120 exposure level surface or ground level, and wherein batting surface 114 uses conventional face angle well known by persons skilled in the art and face angular measurement instrument to locate with angle, face and/or face angle.
With reference to figure 7, batting surface 114 has and extends to top surface 118 from basal surface 120 and the substantially flat or smooth surface extending to front surface heel side line 111 from toe 112.The boundary line that substantially flat batting surface 114 connects the transitional surface of the arc extended in hosel 104 delimited by front surface heel side line 111 (dotted line illustrates).Batting surface 114 has the length L defined to toe direction from toe 112 to front surface heel side line 111 at heel and the height H defined from top surface 118 to ground in top-to-bottom direction.When club is in reference position, length L is horizontal survey, and height H is vertical survey.
In addition, batting surface 114 can be provided with and strengthen club head and to hold with a firm grip during clashing into the line (score line) 115 of golf, groove or other surface characteristics or texture.Hold with a firm grip and strengthen region or hitting region 114a and can usually to be rule (or other hold with a firm grip strengthen surface characteristics) border L1 (dotted line illustrates) and toe side line (or other enhancing surface characteristics of holding with a firm grip) border L2 (dotted line illustrates) and defining in these heel lateral and the top peripheral edge of batting surface 114 extended between toe side boundary line L1, L2 and the section of bottom peripheral edge 118,120 by heel lateral.Therefore, hitting region 114a has length Ls (extending between border L1 and border L2) and height H s (extending between top 118 and basal surface 120).Generally speaking, this height increases in toe direction.The centre line L 3 of hitting region 114a can be positioned at the midway of the length Ls along hitting region 114a.Center, the face Cs of hitting region 114a can be positioned at along the midway (see Fig. 7) of height H s in centre line L 3.(line L1, L2 and L3 can be associated with the cross section of the such as impenetrating thickness shown in Fig. 3 and Fig. 8 A, 8B and 8C respectively.Therefore, the point on rear surface 116 and/or basal surface 120 can define by reference to line L1, L2 and/or L3.)
According to aspects of the present invention, and with reference to figure 1 and 8A-8C, club head 102 can be characterized as being the part 140 (that is, a part for usually thick than blade-section 130 club head 102) having vane type part 130 and thicken.Blade-section 130 is arranged in the upper part of club head 102 usually, and the part 140 thickeied is arranged in the low portion of club head 102 usually.
The blade-section 130 of relative thin generally includes the whole upper part of club head 102.According to some embodiments, blade-section 130 can have less constant thickness T b(see Fig. 8 A-8C), thickness T bsuch as about 6.35mm can be less than.Perpendicular to batting surface 114 detect thickness T b.According to other embodiment, blade-section 130 can have the thickness T changed from top to bottom surface b.Such as, the thickness T of blade-section 130 bprogressively can increase, at top place, there is minimum thickness.At the thickness T of blade-section 130 bin other change can be obvious for those of ordinary skill in the art.Such as, the thickness T of blade-section 130 bcan from heel 110 to toe 112 progressively and monotone increasing.Alternatively, blade-section 130 can have local strengthening rib or periphery mass (not shown).
The low portion that the part 140 thickeied is arranged on club head 102 usually allows redistributing of the weight in club head 102.Therefore, the part 140 of this thickening can help balanced ball club head 102 thus improve swinging dynamically and the track of the golf hit of user.When comparing with common blade formula club head, the part 140 of thickening can make center of gravity and move towards toe downwards.When compared with conventional dorsal muscles formula club head, the part 140 of thickening can make center of gravity move towards toe.The part 140 thickeied has the thickness T of the thickness being greater than blade-section 130 Anywhere c(see Fig. 8 A-8C).Perpendicular to the thickness T that batting surface 114 is measured ccross over length direction and the short transverse change of club head 102.
According to some aspects and referring back to Fig. 2 and Fig. 8 A-8C, Lower rear surface region 116b defines a side in the region (that is, the part 140 of the thickening of club head 102) of thickening.Second side of the part 140 thickeied is defined by basal surface 120.3rd side of the part 140 thickeied is defined by batting surface 114.Therefore, the shape of cross section of the part 140 of thickening can be general triangular.
Rear surface 116 is positioned at the rear portion relative with batting surface 114 or the back of golf club head 102.Rear surface 116 usually extends to bottom 120 from heel 110 to toe 112 from top 118.With reference to accompanying drawing, rear surface 116 comprises two general areas: upper rear surface region 116a and Lower rear surface region 116b.Upper rear surface region 116a is associated with vane type part 130, and Lower rear surface region 116b is associated with the part 140 of thickening.
With reference to figure 1 and Fig. 8 A-8C, Lower rear surface region 116b can demarcate (being represented by outline line) at transitional region 121 place from upper rear surface region 116a substantially.Usually, such as when embodiment illustrated in the accompanying drawings, do not have obvious border to be separated with upper rear surface region 116a by Lower rear surface region 116b, and the transition between Lower rear surface region 116b and upper rear surface region 116a will be set to the surface of arc gradually.In this case, line of demarcation 121a can be defined between upper rear surface region 116a and Lower rear surface region 116b by one group of point, wherein tangentially contacts the surface in transitional region 121 with the line of batting surface 114 one-tenth miter angle.
