Abstract

The utility model relates to a compound driver of a golf, which is made of metallic material. An empty zone is formed at the striking surface of the driver; the empty area is communicated with the back of the driver to cause the compound materials to be fully filled and consolidated in the empty area, and the compound materials are bared on the back of the driver. The design of the utility model causes the metallic materials with high density and fine wearing resistance to be distributed at the circumference of the striking surface of the driver, the compound materials with small density and slightly-small hardness to be arranged on the striking surface and penetrated to the back of the driver. Thus, the center of gravity of the driver is moved backward, and the inertia moment is increased. Thereby, the sweetpoint area of the striking surface of the driver is increased to improve the directional veracity and to reduce the error.

Description

Compound driver of golf

The utility model relates to a kind of golf club head, is meant a kind of golf composite balls caput especially.

The material of golf iron club head was to be made at most with simple metal stainless steel or other metal materials in the past, especially stainless steel material, its reason is that the intensity of stainless steel ball caput is good, the hardness height, touch is good, and cheap, still, with regard to integral body, metal club head still has many shortcomings to exist: density is big, volume is little, moment of inertia and scope of attack dessert (SWEET POTNT) area are all less etc.

In in 1992, the open club head face of U.S. occupation golf association (PGA) allows after the two or more materials, the composite balls caput that a large amount of metal bodies sticks carbon fibre composite promptly appears on the market, but, because the poor bonding strength between metal body and the carbon fibre composite, and fail to change the design characteristics that original metal is made club head, do not obtain preferable market reaction yet.

In order to overcome the deficiency of above-mentioned prior art, main purpose of the present utility model, be to provide a kind of golf composite balls caput, make club head have bigger moment of inertia, and scope of attack dessert (SWEET POINT) area of club head is increased, and can improve the accuracy of direction, and reduce error.

Secondary objective of the present utility model is to provide a kind of golf composite balls caput, makes the club head center of gravity degree of depth move backward, ball is hit out being easy to, and cooperates the depressed trajectory design, and it is farther that ball will fly.

For finishing above-mentioned goal of the invention, golf composite balls caput of the present utility model.Employing is made club head by metal material, the scope of attack in club head forms the hollow out zone, hollow out zone also communicates with the club head back, composite is filled to be cemented in the hollow out zone, and be exposed to the club head back, this kind design, make density is big and wearability is good metal material be distributed in the club head scope of attack around, and density is little, the composite that hardness is slightly little then is positioned at the scope of attack and is through to the club head back, the center of gravity degree of depth is moved backward, and it is big that moment of inertia becomes, and makes scope of attack dessert (SWEET POINT) area of club head increase, and thereby improve the accuracy of direction and reduce error.

For the definition of scope of attack dessert (SWEET POINT) area, the utility model limits as follows:

1, the best dessert position of hitting: general golf club head, because of there being the characteristic of distribution of weight (also to be, moment of inertia), therefore, when a club head with certain speed of hitting, correctly hit the golf of a fixed weight, and beat square stance in certain position of club head, can make ball produce the fastest flight initial velocity, this position is called the dessert or the best dessert position of hitting of club head

2, hit the dessert zone: because the above-mentioned position that can make ball produce the fastest flight initial velocity, be not a point but a zone usually, for the purpose of practicality, define zone in the 95% the fastest flight initial velocity usually for hitting the dessert zone.

3, scope of attack dessert area: the area in the strike dessert zone in the above-mentioned 95% the fastest flight initial velocity is commonly referred to as golf scope of attack dessert area.This area is bigger, and the initial velocity that expression golf is flown out by the club head strike, the probability in prestissimo 95% are bigger, and healing apart from probability that its flight that produces relatively is farther is big.

In order to realize the technical solution of the utility model, the existing preferable possible embodiments of accompanying drawings.

Fig. 8 is the B-B cutaway view among Fig. 7.

Shown in Fig. 1-4, the golf composite balls caput of the utility model preferred embodiment, club head 10 is to be made by metal material (present embodiment is that the act stainless steel material is an example) substantially, and metal material is distributed in the shank 11 of club head 10, neck 12, around bottom 13 and the back 14 and the scope of attack 15, and when making club head 10 moulding by metal material, the scope of attack 15 in club head 10 forms hollow out zone 20, it is to be example with three rooms that the back 14 of hollow out zone 20 and club head 10 connects the room 30(present embodiment that is provided with predetermined number mutually), and utilize mould (not showing on the figure) with the heating pressuring method, with composite 40(present embodiment is to be example with the carbon fibre composite) fill and to be consolidated in hollow out zone 20 and the room 30, towards the scope of attack 15, and be positioned at 30 of two rooms and respectively convex with reinforced ribs 50, make the metal material position of composite 40 and club head 10, can firmly combine.

Shown in Fig. 5-8, be another preferred embodiment club head 60 schematic diagrames of the utility model, its structure is same as the previously described embodiments substantially, different places are: the hollow out zone 70 of club head 60 is directly to run through to communicate in the back 64, so that be positioned at composite 90 areas at club head 60 backs 64, must be greater than the position at 1/5th of composite 90 areas of the scope of attack 65, and respectively convex with a reinforced ribs 80 in 70 two sides, hollow out zone, make composite 90 can be cemented in the bulb 60.

By above explanation as can be known, golf composite balls caput of the present utility model compared with prior art has following advantage:

1, the utility model golf iron club head 10, with the metal designs of density big (7.8g/cc) in club head 10 outer rims, club head 10 middle bodies are through to back 14 by the scope of attack 15 and then are the composite 40 of density less (1.5g/cc), and this kind is with club head 10 structures of distribution of weight in outer rim, can have bigger moment of inertia, make scope of attack dessert (SWEET POINT) area of club head 10 increase, and as shown in the above description, scope of attack dessert area increases, golf is hit the initial velocity that flies out by the baseball head, probability in prestissimo 95% is bigger, so, the error of batting just can significantly reduce relatively, and the direction accuracy of batting also improves greatly.

2, club head 10 outer rims are to be made of the preferable metal material of wearability, make can obtain protection by a composite 40 in club head 10 inside, be unlikely because of the collision or the damage to some extent of contacting to earth, so, can improve service life again.

3, low-density composite 40 and metal composite, make the distribution of weight of club head 10 have more Flexible Design, and volume ratio conventional metals bat is big first watch, cause the center of gravity degree of depth will be darker than Metal Ball caput, because the center of gravity degree of depth is darker, so square stance is got ball easilier, and cooperate the design of depressed trajectory, ball will fly fartherly.

The design of another preferred embodiment of the present utility model also can reach effect same as the previously described embodiments.
