The specific embodiment
According to one embodiment of the present invention, in game process, golf club head is used as " striding beam " (to call " under impact load " in the following text) when taking place to impact with golf.Generally speaking, the surface of golf club head is corresponding to striding the beam drag-line, strides the beam truss and stride the beam inertial support system to be in surperficial rear portion.Like this, the weight that is similar to the golf club head of striding beam just can drop to minimum, supports thereby carry out inertia under dynamic load.
For ease of reference, " striding beam " this term is used for expression and strides girder construction body and the revised girder construction body of striding.In striding the girder construction body, most of property class of structure is similar to strides the beam characteristic, has only the architectural characteristic of small part, except solid, plate, face housing.Stride in the girder construction revised, the part-structure property class is similar to strides the beam characteristic, has also increased the part-structure characteristic, such as solid, plate or face housing.
In a word, as striding beam, it can have one and relax some golf club head under impact load, and its apparent height that passes golf club head extends, and its center of gravity can be near the surface of golf club head.Stride the beam truss and be in surperficial rear portion, can under impact load, produce specific deflection efficiency, stride the beam inertial support system a kind of specific inertia square can be provided.In addition, the quality of the golf club head of needs support impact load can be less than the quality of the required golf club head of " housing " golf club head.Can make the inertia properties of golf club head reach best like this.
Fig. 1 is a golf club head embodiment vertical view, is used as under impact load and strides beam.In golf club head 100, surface 110 links to each other with inertial support system 120 and power delivery system 130.Back structure 140 links to each other with power delivery system 130 and surface 110.Power delivery system 130 comprises two parts, i.e. structure therein 130a and radial structure 130b.
For ease of explanation, " connections " this term is used to represent being operatively connected between entity connection between the structure and the structure.Such as, " structure A links to each other with structure B " means: (1) structure A links to each other with the structure B entity; (2) structure A is to interact with structure B under the operating condition; Perhaps (3) structure A is connected with the structure B entity under operating condition, and structure A and structure B interaction.
Under off-center impact load, inertial support system 120 " rotation " that golf club head 100 produces because of off-center impact load of also can setovering.Such as, when golf club head impacted position between golf upper surface center and the golf club head top, golf club head just rotated around longitudinal axis.Like this, golf just can move along unexpected direction.Biasing by inertial support system 120 is provided can reduce the rotation of golf club head.In other words, inertial support system 120 can be golf club head 100 a kind of high inertia square is provided.
Generally speaking, under impact load, the power delivery system 130 that links to each other with inertial support system 120 can prolong back structure 140, thus " bending " of control surface 110 (and the deflection on surface 110), and the deflection efficiency of control surface 110.Such as, power delivery system 130 and inertial support system 120 can be with the deflection efficiencies identical with the stroke rate of golf, and the deflection efficiency of coming control surface 110 can reach the impedance match between good dynamic response and surface 110 and the golf thus.According to golf game person's viewpoint, good impedance match means the good driving distance of golf.In the another kind of embodiment of golf club head 100, back structure 140 also can link to each other with power delivery system 130 and inertial support system 120, thus the bending of control surface 110, and the deflection efficiency of control surface 110.
In addition, under on-center impact load, power delivery system 130 and back structure 140 are substantially similar to one and stride the beam truss, and power delivery system 130 and back structure 140 are in axial compression state or axial tension state.Especially, structure therein 130a and radial structure 130b are in axial compression state (length along structure is come " pushing "), and then 140 of structures are in axial tension state (length along structure is come " elongation ").
All reaching with one heart under the off-center impact load, surface 110 produces crooked under impact load.But shown in Figure 12 a, if watch from the surface of " cydariform " golf club head, each beam mode is all different.The cydariform golf club head is hereinafter referred to as diaphragm golf club head, and along the vertical line (with respect to horizontal line) from surperficial top margin to surperficial base, the surface curvature pattern of measuring is uneven.In other words, if along vertical line A
0To A
10, A then
0May be not equal to A to post deflection
1To post deflection, and A
1May be not equal to A to post deflection
2To post deflection, and A
2May be not equal to A to post deflection
3To post deflection.The reason of non-homogeneous bending is the design of diaphragm golf club head, and it need be rigidly connected along its top, bottom and side on the surface.
In golf club head 100, if measure along vertical line (with respect to horizontal line) (to call " being similar to the deflection of beam pattern of striding " in the following text), then the beam mode on surface 110 is uniform from surperficial top margin to surperficial base substantially.In other words, along vertical line B
0To B
10, B
0Equal B substantially to post deflection
1To post deflection, B
1Equal B substantially to post deflection
2To post deflection, B
2Equal B substantially to post deflection
3To post deflection.Like this, compare with the diaphragm type golf club head with mitigation " point " (the lip-deep point of diaphragm type golf club head), surface 110 has mitigation " line " (series of points on the surface 110 of golf club head 100).Golf club head lip-deep " mitigation " district is the best region that transmits energy from the surface of golf club head to golf.
The insider as can be known, " along vertical line (with respect to horizontal line) " this term is used for reference purpose.In operation, in many golf club heads, the vertical axis of club face may be not orthogonal to horizontal plane.On the contrary, the vertical axis of club face may with horizontal plane at angle (such as, specific relatively " impacting " distributes and is orientated).Like this, on this club face, may be similar to the deflection of beam pattern of striding along the parallel lines of club face vertical line.In addition, in many golf club heads, the surface of golf club head may not be plane (having the roller bar such as the surface).For this club face, can be similar to the deflection of beam pattern of striding along the curved surface tangent line of golf club head.In other words, being similar to and striding the deflection of beam pattern is a kind of beam mode of surperficial 110, under following measurement situation, this beam mode is from being uniform basically near the base on surface 110 near 110 the top margin of surface: along vertical line (with respect to the horizontal plane) measure, surfacewise the parallel lines (with respect to the horizontal plane) (may be not orthogonal to horizontal plane) of 110 vertical axis measure or surfacewise 110 curved surface tangent line measure.
In the another kind of embodiment of golf club head 100, the beam mode on surface 110 is that a kind of " through revising " is similar to the deflection of beam pattern of striding.Striding in the deflection of beam pattern through being similar to of correction, the maximum deflection on each shock point (and deflection efficiency) betides on the major part on surface, and has roughly the same value.In other words, in the C district on surface, because of impacting I
1(betide lip-deep point [X
1, Y
1] locate) and the post deflection Z of generation
1Substantially equal because of impacting I
2(betide lip-deep point [X
2, Y
2] locate) and the post deflection Z of generation
2, because of impacting I
2And the post deflection Z that takes place
2Substantially equal because of impacting I
3(betide lip-deep point [X
3, Y

3, because of impacting I
3And the post deflection Z that takes place
3Substantially equal because of impacting I
4(betide lip-deep point [X
4, Y
4] locate) and the post deflection Z of generation
4Like this, although impact I
1, I
2, I
3And I
4All be in the difference place of surface on 110, but the deflection that takes place because of impact is equal substantially, i.e. Z
1≈ Z
2≈ Z
3≈ Z
4... ≈ Zn, in addition, the deflection efficiency that takes place because of impact is also equal substantially, i.e. Z
1≈ Z
2≈ Z
3≈ Z
4... ≈ Z
n
On the contrary, shown in Figure 12 b, in the diaphragm type golf club head, the maximum deflection amount (and deflection efficiency) on each shock point betides in most of zone on surface, and they do not have identical value.In other words, in surf zone D, because of impacting I
1(betide lip-deep point [X
1, Y
1] locate) and the post deflection Z of generation
1Substantially be not equal to because of impacting I
2(betide lip-deep point [X
2, Y

2, because of impacting I
2And the post deflection Z that takes place
2Substantially be not equal to because of impacting I
3(betide lip-deep point [X
3, Y

3, because of impacting I
3And the post deflection Z that takes place
3Substantially be not equal to because of impacting I
4(betide lip-deep point [X
4, Y
4] locate) and the post deflection Z of generation
4Like this, in diaphragm golf club head, because of the deflection that impact takes place unequal substantially, i.e. Z
1≠ Z
2≠ Z
3≠ Z
4... ≠ Zn, in addition, because of the deflection efficiency that impact takes place also unequal substantially, i.e. Z
1≠ Z
2≠ Z
3≠ Z
4... ≠ Z

In one embodiment of the invention, the area of " mitigation " on surface 110 point specific surface 110 is big by 25%.In each embodiment in mitigation district (line and face) surperficial 110, but each zone angulation, thus specific golf game person (or one group of golf game person) optimum Match golf is impacted distribution.Such as, the mitigation district on surface 110 horizontal plane relatively forms 30 ° of angles.
As mentioned above, under off-center impact load, surface 110 bends to the pattern of striding beam that is similar to.In addition, during off-center impact load, 120 reaches of part surface 110 relative inertness support systems.The part surface 110 of relative inertness support system 120 reaches is in the opposite on the surface of being impacted by golf 110.The reach force transfer system of part surface 110 under off-center impact load and the control of back structure, it stems from one of similar golf club head characteristic of striding beam, although promptly the center line of golf game person departure surface 110 impacts golf, but still can drive the ability of golf along ideal orientation.
