Abstract

The utility model relates to an improved structure of a neck of a head of a golf club. The utility model is provided with a head, the side of which is provided with a neck, the neck can be inserted with a shaft. The utility model is characterized in that the neck is provided with a flexing section for enhancing the bending elasticity between the shaft and the head.

Description

A kind of improvement structure of golf club Head and Neck

The utility model is relevant with golf driver head, particularly has height husband's bar head of deflection section about a kind of neck.

Known its neck of metal golf driver head mainly is for the usefulness of axostylus axostyle grafting, requires neck to have quite high structural strength and rigidity in the design, and its axostylus axostyle then provides the bending elasticity of the batting that swings.If the bending elasticity of axostylus axostyle is stronger, its can make golf clubs with ball hit farther, but its relative rigidity a little less than, the square stance bar head drop point that causes swinging is unstable, its ball-handling property is relatively poor.Otherwise if the rigidity of axostylus axostyle is stronger, its square stance bar head drop point that swings is more stable, and ball-handling property is preferable, but its bending elasticity a little less than, hitting distance will be shorter.

Main purpose of the present utility model is to provide a kind of improvement structure of golf club Head and Neck, and it can make golf clubs take into account simultaneously and hit far and ball-handling property.

For reaching above-mentioned purpose, the improvement structure of a kind of golf club Head and Neck that provides according to the utility model, it is to be provided with a deflection section in bar Head and Neck position, use the bending elasticity of promoting club, therefore axostylus axostyle promptly can adopt the rigidity preferably, to promote ball-handling property, can remedy the bending elasticity of club simultaneously again by neck deflection section.

In addition, this deflection section also can be made into flat, make its at minor axis to having preferable bending elasticity, and at major axis to having preferable rigidity, by this deflection segment length axially and the angle design of bar head batting surface, can obtain to have the club of preferable bending elasticity at specific direction.

For further specifying the purpose of this utility model and feature, cooperate graphic being described as follows for four embodiment now, wherein:

Fig. 1 is the stereoscopic figure of the utility model first embodiment.

Fig. 2 is the cutaway view along 2-2 hatching line among Fig. 1.

Fig. 3 is that the utility model second embodiment is along the cutaway view that is same as Fig. 2 hatching line direction.

Fig. 4 is the stereoscopic figure of the utility model the 3rd embodiment.

Fig. 5 is the cutaway view along 5-5 hatching line among Fig. 4.

Fig. 6 is the stereoscopic figure of the utility model the 4th embodiment.

Fig. 7 is the cutaway view along 7-7 hatching line among Fig. 6.

As shown in Figure 1, 2, the golf driver head 10 of the utility model first embodiment is club heads, yet it also can be an iron club head, this bar head 10 has a head component 11, an and neck piece 12, be combined in head component 11 with hard solder, this neck piece 12 can be pegged graft for an axostylus axostyle 100, is provided with the less cylindrical deflection section 13 of an external diameter in the middle of neck piece 12.Independent or the many persons be combined intos of metal material such as this head component 11 can stainless steel, aluminium alloy, titanium alloy or magnesium alloy, this neck piece 12 also is to make with metal, the thickness of its deflection section 13 (diameter), length, and soft or hard (soft or hard of neck material) all can influence the flexibility and the ball-handling property of bar head 10, so bar head manufacturer can obtain bar head with different waving property of deflection by the assembling unlike material with the neck piece 12 of shape.Use bar head of the present utility model can use the stronger axostylus axostyle group bar of rigidity, can obtain preferable ball-handling, the elasticity (that is hitting distance) that causes in club then can be supplied by the deflection section elasticity of bar head itself, so can obtain to have concurrently the club of ball-handling property and hitting distance.And the bending point of this kind club (Kitpoint) can approach or be sitting at the deflection section of bar Head and Neck, can effectively reduce the amplitude after club is batted.

As shown in Figure 3, be second embodiment of the present utility model, deflection section 23 sections of its display pole head 20 necks 22 are oblong, this kind section configuration at minor axis to having higher bending elasticity, at major axis to then having higher rigidity, therefore suitable these deflection section 23 major axis of design are to (being represented by dotted lines among the figure, label 231) with the angle of bar head 20 striking surfaces 24, can obtain to have preferable bending elasticity at a certain specific direction, at the special club that other direction then has preferable rigidity, the deflection segment length axle 231 of present embodiment is approximately parallel with striking surface 24.

As shown in Figure 4, the bar head 30 of the utility model the 3rd embodiment also is with hard solder unification neck piece 32 at head component 31 sides, this neck piece 32 is provided with the deflection section 33 of a flat in the centre, as shown in Figure 5, the major axis center line 331 in the cross section of this deflection section 33 and bar head batting surface 34 are angle about 60 degree (among the figure 1 o'clock direction) approximately, the 30 easily bar head heel 35 direction deflection deformations of this kind bar head, therefore direction of stroke easily flies toward left direction, can effectively proofread and correct its inclined to one side mistake to the batting custom direction person of flying that turns right.

As shown in Figure 6, the utility model the 4th embodiment is an iron club head 40, also be at a head component 41 side hard solder unification neck piece 42, the cross section major axis center line 431 of neck piece 42 deflection sections 43 and bar head batting surface 44 are angle about about 60 degree of other direction (among the figure 11 o'clock direction), and this kind bar head 40 is easily toward the 46 direction deflection deformations of bar head toe.In addition can a sheathed rubber or plastic cement or elastic external members 47 such as its mixture or its foaming body in these deflection section 43 outsides, make neck 42 form a smooth-going moulding in appearance, do not have the notch position, so promptly do not have lofty sensation in appearance, this external member 47 can be used chromatic colour in addition, not only has outside the decoration function angle that still can colouring discrimination deflection segment length shaft centre line.

The utility model compared with prior art has: golf clubs is taken into account simultaneously hit far away with The function of ball-handling property.
