Specific embodiment
The preferred embodiment of glof club head 10 with structural connection is shown in Fig. 1-8.Glof club head
10 preferably include main body 20, and main body 20 has the impact surface section 30, separate impact surface section 30 for having center of face 34
Section (return section) 32 that top edge 31 extended back return, the lower edge 33 far from impact surface section 30 prolong backward
The base segment 22 stretched, the bar neck 24 for engaging axis, heel end 23, toe end 25, upper opening 26,27 and of hollow inside
Tail end 28.Bizet section 40 includes return section 32 and bizet insertion piece 42, and the bizet insertion piece 42 is placed on upper opening
With closes hollow interior 27 on 26.Main body 20 further include three notch 70 in the central area of base segment 22 21,72,
74, it is closed by the covering members 80 with density more lower than the density of the material for manufacturing main body 20.40 He of bizet section
Each of covering members 80 are preferably made of carbon composite, while main body 20 is by the metal material of such as titanium alloy or steel
It constitutes.
In hollow inside 27, two structural connections 50,52 are approximately parallel to the rear surface 36 of impact surface section 30 simultaneously
And section 32 of returning is extended up to from base segment 22 in parallel with each other.In an alternative embodiment, structural connection 50,52
Alternatively extend to bizet insertion piece 42；Importantly, even if when impact surface section 30 hit golf when, structural connection
50,52 also bizet section 40 is connected to close to impact face in the case where not contacted with any part of impact surface section 30
The base segment 22 of section 30.Under any circumstance, for the tail end 28 away from main body 20, structural connection 50,52 is all
It must be closer to impact surface section 30.
As shown in Figure 3, preferred embodiment tool is each in structural connection 50,52 there are two structural connection 50,52
A is the solid hopkinson bar being made of lightweight, firm metal material (such as titanium alloy or steel), but in an alternative embodiment,
Each of structural connection 50,52 can be hollow tube or made of firm light-weight metal or composite material it is other in
Hollow structure.In another embodiment, glof club head 10 may include both structural connections 50 of solid hopkinson bar and hollow type.
Structural connection 50,52 is preferably used wax molding process and main body 20 and casts jointly, but in an alternative embodiment, can be with
Structural connection 50,52 is added after main body 20 is manufactured and via welding, soldering, solder or adhesive and/or mechanically
It is fixed to main body 20.
In a preferred embodiment, each of structural connection 50,52 all has 0.050 inch to 0.200 inch straight
Diameter and 1 to 2.5 inch of length.Structural connection 50,52 is both preferably positioned to the rear table in impact surface section 30
It (is measured along the perpendicular 60 for extending through center of face 34 perpendicular to impact surface section 30) in 1 inch of face 36.Any knot
Any part of structure connector 50,52 shall not be positioned in except 1 inch of the range；In fact, it is highly preferred that each
Structural connection 50,52 is positioned to the rear surface 36 even more close to impact surface section 30.In a preferred embodiment, structure connects
Fitting and rear surface 36 are spaced 0.136 inch to 0.210 inch, and the wherein upper end of each structural connection 50,52
50a, 52a spacing distance D1, distance D1Than the space D of lower end 50b, 52b2It is somewhat closer to rear surface 36.It is being preferably implemented
In example, D1In the range of 0.120 inch to 0.150 inch, while D2In the range of 0.180 inch to 0.210 inch.Knot
Structure connector 50,52 is also spaced each other 0.500 to 2.00 inch, more preferably 0.75 to 1.50 inch approximate, and most preferably
Approximate 1.00 inches of the distance D in ground3.When being tested according to United States Golf Association (USGA) CT with μ s measurement, structural connection
50, the 52 this positioning and optimizing relationship of standardization ball speed and characteristic time (CT).
Standardized ball speed to golf with any given glof club head (including golf of the invention
Head 10) speed when hitting test in eliminate the quality and loft and specific golf of glof club head
Construction variable influence；In other words, allow the comparison of the same benchmark of glof club head performance.It is able to use following step
Suddenly determine that standardized ball speed, these steps are also summarized in the flowchart of fig. 9 for glof club head.
Firstly, as shown in Figures 10 and 11, providing with approximate 190 grams of quality, approximate 4 inches of diameter D4, it is approximate
0.100-0.150 inches of minimum thickness T1With approximate 0.200-0.400 inches of maximum gauge T2Titanium 6-4 calibration plate 90, and
And 92 (the step 100) of center of the test golf beating calibration plate to approximate 109mph movement.Measure the return speed of ball
Spend Vbr(step 110).Then, it is struck with the center 34 of the impact surface section 30 of evaluated glof club head 10 again with close
Like the identical test golf (step 120) that 109mph advances, and measure the rebound velocity V of test golfcr(step
It is rapid 130).Then, the quality m with data board is measuredp, golf quality mb, glof club head 10 quality mc, measure
Head test ball speed (109mph target) Vcin, measure plate test ball speed (109mph target) Vbin, measure
Ball return speed V is tested on headcrBall return speed V is tested with the plate measuredbr(step 140).Finally, using following equation meter
Calculate standardized ball speed (Vballnorm) (step 150):
In the equation, VinhFor 100 and mhIt is 200.
Glof club head 10 of the invention has Vballnorm>=0.0356x+140.82, and more preferably Vballnorm
≥0.0356x+141.19.The positioning of structural connection 50,52 allows glof club head 10 to meet the equation；Such as institute in Figure 12
Show, does not include that the glof club head of the prior art of structural connection structure cannot reach this performance indicator completely.
Other than the standardization ball speed of optimization glof club head 10, stiffener 50,52 is located in and is defined above
Glof club head 10 region in glof club head 10 have maximum stress reduction effect.If any structure connects
Fitting 50,52 is placed with the rear surface 36 away from impact surface section 30 greater than 1 inch, then when glof club head 10 is in use
When, will there is no significant impact to the stress being applied in impact surface section 30, and any quality will be used not provide but
Significant performance benefit.
