Description

Head of golf club {Head of iron golf club}

The present invention relates to a head of a golf club, and more particularly, to a golf club of a golf club, especially iron or fairway wood, hybrid type of the golf club to provide a shock absorbing function and to improve the feel and improve the emotional beauty of the golf club A head portion of a golf club having a configuration that provides various effects such as providing an increase is provided.

Applicant has made a number of prior applications that share the same basic concept as the present invention, the present invention has a technical spirit similar to this prior application, and limited to golf clubs, especially 'head' of the iron or fairway wood, hybrid type It is characterized by providing a localized and limited improved configuration.

Therefore, the iron in the present invention will include all clubs of the iron type, such as irons, wood irons, wedges, utility irons, hybrid irons, fairway wood, hybrid golf clubs.

Among golf clubs, iron, fairway wood, and hybrid type golf clubs are made of solid forgings, castings, etc., and have a neck, which is connected to the shaft and has a certain amount of force. It is a club.

Therefore, in the operation of the iron, the impact on the golfer's hand and shock absorption to prevent damage to the hands, cuffs, shoulders, etc. is a major design point, especially iron, fairway wood, hybrid type golf clubs Shock-absorption is becoming a very important aspect because it requires a hitting action.

Considering this point, a configuration for shock absorption has been devised. Among them, as in the head of a golf club in Korean Patent Publication No. 1995-0000181,

In a head of a golf club having a blade, a hazel, and a connecting portion connecting the blade and the hazel, the blade has a surface for hitting a golf ball, and the blade is formed of a first material. It is

The part of the head is deformed so that the hazel is formed of a second material having a specific gravity smaller than that of the first material, thereby absorbing the shock according to the physical properties of the material and inserting a perforated bracket inside the hosel part, thereby achieving a shock absorbing effect. There is one thing.

However, in the case of the above-mentioned source configuration, it is extremely difficult and expensive to manufacture a single iron by using different materials, and even when using a bracket, it is difficult to obtain a desired shock absorbing effect to the extent of drilling into a plate-like bracket. There is not actually application.

Therefore, the head of the golf club of the present invention can be configured inexpensively in view of these problems, while minimizing the impact transmission to the body of the golfer and providing an elastic configuration to increase the distance, and further to the golfer's psychological appeal. This study aims at the side effects of improving golf club operability.

The head of the golf club of the present invention for achieving the above object;

Head body including iron, wood iron, wedge, utility iron, hybrid iron and fairway wood, hybrid type golf club, and the other side, the sole (Sole) and the back portion (Back), and the head body In the head of the golf club having a hosel (Hosel) for connecting the shaft and the neck portion; It is a basic technical idea to further have a cross-sectional coefficient adjusting means for reducing the cross-sectional area of the hosel and neck,

The section modulus adjusting means is one or more recessed holes,

In the case of two or more of the holes, the diameter of the horizontal cross section and the depth of the vertical cross section may be different with respect to the length of the hosel of the hole.

The section modulus adjusting means is a specific selective technique that is one or more tubular shaped perforations to be drilled through the hosel or the neck.

The head of the golf club of the present invention increases the function of the elastic body in the microscopically due to the reduction of the cross-sectional coefficient in the transmission process of transmitting the impact amount applied to the head body to the hosel, and connects the (microscopic) spring between the headbody and the hosel. As the shock absorber is absorbed.

By this action, by dispersing and absorbing the amount of impact delivered to the golfer's hand has the effect of reducing the induction of elbow or damage to the wrist joint, shoulder joint damage, muscle damage.

In addition, as the weight of the entire neck or hosel decreases, the weight of the head body must be increased in order to comply with the prescribed total weight. Therefore, the increased weight of the head body increases the operating speed of the head at the time of hitting. Therefore, it has the effect of increasing the flying distance by increasing the total amount of moment.

In addition, it was found that there is a psychological improvement effect such as an increase in hitting feeling by the elasticity felt by the golfer and a confident swing.

The head of the golf club head of the present invention is a fairway wood, hybrid type golf club that requires the operation of the ball hitting all the clubs of the iron type, such as wood irons, wedges, utility irons, hybrid irons, as well as irons Of course it applies.

As in the conventional configuration of Figure 1,

Conventional irons (hereinafter referred to as 'irons', including both fairway wood and hybrid golf clubs) are the other side (F), the sole (S: Sole) and the back (BK: Back) head. Body (B), the head body (B) is a configuration having a neck (N) connected to the hosel (H: Hosel) to which the shaft is connected to form a head (H) and the head (H) of the solid body Castings or forgings.

In the conventional iron (I) of such a structure, when a golfer hits the ball, the vibration which generate | occur | produced by the hit with the golf ball in the other surface F generate | occur | produces, and the vibration passes through the solid part of the head H. The total shock is transmitted to the shaft via the hosel (H).

The hosel (H) is also molded in a solid body other than the shaft tube (V) into which the shaft is inserted, so most of the shock is transmitted without relaxation or elastic absorption.

This conventional configuration of iron (I) is a structural impact, in particular in the case of the so-called 'stretching', which is the operating characteristic of the iron, a considerable impact impact is transmitted to the golfer's hand by impact with the ground, so that the elbow of the joint There was a problem of causing a lot of induction or shoulder muscle damage, but no means of mitigating shock are provided.

The head of the golf club of the present invention in view of the above-described problems of the iron (I) of the conventional configuration is to be solved by changing the geometrical configuration including the adjustment means of the section coefficient of the hosel (H) portion.

The iron I1 of the basic structure to which the basic idea shown in FIG. 2 is applied is demonstrated.

As shown in the perspective view seen from the side in FIG.

As a section modulus adjusting means in the neck portion N connecting the hosel H and the head body B.

One or more recessed holes 10 and 11 are provided to have a predetermined depth while having various cross-sectional shapes that are recessed and cut or integrally cast.

The depressions 10 and 11 will be machined into various shapes, such as bell, triangle, square, etc., as their cross sections are shown.

The drawing shows the formation of a relatively large inlet hole 10 and a small inlet hole 11, and the horizontal cross section of the inlet hole 10 and 11 with respect to the hosel H is circular, polygonal, or star. It may be a variety of shapes, such as shape, the vertical cross-section may be a variety of triangles, ovals, rectangles, such as Figure 5a.

If necessary, the inlet holes 10 and 11 may be blocked with a separate synthetic resin material, rubber material, urethane, or the like to prevent the intrusion of rainwater and form a beautiful appearance.

FIG. 3 is a perspective view of the rear side with the angle of view of the embodiment of FIG. 2 changed. FIG.

4 shows different numbers of recessed holes 10, 11 and 12, and the number of the recessed holes 10, 11 and 12, and the diameter and depth of each of the recessed holes 10, 11 and 12 are irons. It is determined experimentally to obtain the section modulus at the most ideal neck N so as to be suitable for achieving the object of the present invention without sacrificing the strength of (I).

The effect obtained by having a large number of the indentations 10, 11, and 12 is that the impact amount is dispersed stepwise along the longitudinal direction of the hosel (H) can have an increased cross-sectional coefficient control effect.

By providing the section modulus adjusting means composed of such recessed holes 10, 11, and 12 to the hosel H or the neck, the section modulus of the hosel H or the neck portion N is reduced, thus providing the section modulus adjusting means. The modulus of elasticity is increased compared to the case where it is not.

Therefore, compared with the conventional configuration, the impact amount generated when the head H of the iron I hits the golf ball or the ground is lost as a large amount of elasticity loss, and a momentary shock is generated by the golfer's hand with a moderate impact. Is reduced microscopically.

It was found experimentally that this difference is enough to be perceived by the golfer when he is hitting, and to be aware of the effects.

Another configuration of the section modulus adjusting means based on the above technical idea,

As shown in FIG. 5B, one or more perforations 20 may be perforated through the hosel H or the neck N instead of the hole, and the same effect may be obtained.

In the case of the perforated body 20, it is preferable to forcibly fix the perforated stopper 20-1 made of rubber, plastic material or the like in order to prevent migration of foreign matter paper.

Another section modulus adjusting means is shown in Figure 6,

By forming one or more perforated slits 30 and 31 formed long along the longitudinal direction of the hosel H of the iron I2, in addition to the adjustment effect of the section coefficient, the impact amount is dispersed throughout the longitudinal direction of the hosel H. It has an absorbable effect.

As another embodiment, as in the above-described embodiment or modified example, it may be a recessed hole or a perforated body, but as shown in FIG.

The lower end part of the hosel H of the iron I2 is formed in the pipe shape as the section coefficient adjustment means of the hollow tube body, and the shaft tube hole V is spaced apart from the upper end of the control tube part 40. By forming the control tube portion 40 and the shaft tube (V) to be spatially separated.

In this case, even though the cross-sectional coefficient is greatly reduced throughout the longitudinal direction of the hosel (H), the connection strength is not lost due to the structural characteristics of the tube.

As another modification, when the above-described control tube portion 40 is filled with titanium, the same properties can be obtained as the titanium physical properties have high vibration conductivity while increasing strength.

Embodiments using the depression hole of FIG. 2 or below may be additionally modified as follows.

As shown in FIG. 8, the pore cluster 50 composed of a plurality of control pin holes 51, 52... Bored through the hosel H and the neck portion N toward the center of the cross section C over a predetermined area. If formed, as shown in the embodiment of Figure 2 or less, without being damaged by a large diameter hole or aesthetics of the perforated body, close to the small diameter (Pin hole).) Since the sum of the cross-sectional coefficients lost by (51, 52 ...) can be set to be larger than the depression hole or the perforated body of the above embodiment, the elastic effect is increased and the appearance is beautiful.

The method for constructing the pore cluster 50 by drilling the control pin holes 51, 52 ... is directed toward the cross-sectional center C of the hosel H as in the respective modifications taken along the line BB. Made with indents radially recessed,

The hosel is made of a plurality of intersecting perforated pin holes penetrating in the cross-sectional plane, or each control pin hole (51, 52 ...) is filled with a plastic material such as rubber silicone so that the cross section of the filler material As shown in FIG. 3D, the dot protrusions D are apparently disposed to be deformed to increase aesthetics and the like.

As described above, the head of the golf club of the present invention is not limited to the above-described embodiment and modifications, and of course, many modifications are possible.
