Head assembly of golf club
A head assembly of a golf club includes at least one various-shaped aiming mark formed in a centerline aligned with an impact line in a face of a head of a driver, an iron, or putter, or at the position opposite to the aiming mark about the centerline. Since the golfer aims when striking the golf ball, the habit of continuously keeping the golfer's aim to the head of a golf club is accustomed to the golfer such that the golfer naturally habituates the careful swing of a golf club.
1. Field of the Invention
The present invention relates to a head assembly of golf clubs, and more particularly, to an improvement of a head of various golf clubs such as drivers (including fairway woods), irons, and putters.
2. Description of the Related Art
Golf is often referred to as a “mind game”, and a golfer's state of mind is of primary importance in the game of golf. Since the golfer's personality influences their golf game, it is difficult to gain skill in golf.
In particular, since a novice hastily selects and uses golf clubs and the novice may become accustomed to an undesirable golf pose, most novices have difficulty in improving their golf skills.
Generally, there are some important factors required to golfers and in playing golf games such as ‘swinging the golf club relatively slow so as to precisely drive a golf ball along a predetermined lie without failing swing form when backswinging with a golf club’, ‘minimizing cocking, i.e. striking the golf ball or swinging with a golf club only using the golfer's wrists’, ‘applying appropriate force to the golf club when using the golf club’, ‘preventing Headup (phenomenon that a golfer's head does not face impacted golf ball but is lifted up after impacting the golf ball)’, and ‘correcting rhythm and timing when swinging the golf club.’ These factors are significantly affected by the golfer's mental state to hastily swing.
SUMMARY OF THE INVENTIONTherefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a head assembly of a golf club enabling a golfer to visually focus upon a head of the golf club and to stably aim a golf ball after striking the golf ball so as to stably strike the golf ball, to prevent the headup, and to control the backswing.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including an aim guiding device provided on a face of a head of an iron, the aim guiding device including channel-shaped aim guiding channels depressed in the face of the head such that the distance between the aim guiding channels becomes narrow as goes down.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including an aim guiding device provided on a face of a head of an iron, the aim guiding device including a colored part formed on a central portion of the face of the head by metal coloring, knurling, carbon coating, metal power coating, or the like to form an approximate V-shape
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a sight attached to a rear surface of a face of an iron and a putter, the sight being selected from a semispherical or quarter-spherical sight, a solid semispherical sight, and decorated aiming device having various shapes.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a aim guiding device provided to a face of a head of an iron, the aim guiding device including a plurality of slip lines, engraved in the form of engraved lines or protruded lines in a slip area, adjacent to a neck of the head of the iron having a lower side and connected to a head face contacting the ground when impacting a golf ball.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including a various-shaped aiming face formed in a face of a head of a putter in the form of a figure, and rib-shaped aim guiding flags integrally or separately formed with the head and extending backward from the upper side of the head, and an aim guiding protrusion, as a aim guiding device, formed in the aim guiding flag in the form of various-shaped extender.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including at least one aim guiding line, converging to or diverging from an upper reference line of a face of a head of a driver, having various many-sided shapes, and formed in an upper surface of the head by engraving in intaglio or relief, or by printing a ling type print font.
In accordance with the present invention, the above and other objects can be accomplished by the provision of a head assembly of a golf club including at least one various-shaped aiming mark formed in a center line aligned with an impact line in a face of a head of a driver, an iron, or putter, or at the position opposite to the aiming mark about the center line.
According to the head assembly of a golf club in accordance with the present invention, since mentally stable and geometric aiming is achieved, precise impact of a golf ball is achieved and the backswing and downswing of putters are slowly performed. Thus, the golfer can accustom himself/herself to desirable and considerable swinging with the golf club. Moreover, during the most important part of the putter swing, i.e. the backswing, the golfer aims the point where the golf ball is struck by the golf club, and as a result, careless swing is prevented. Thus, due to the aiming, an undesirable headup posture is also minimized.
BRIEF DESCRIPTION OF THE DRAWINGSThese and/or other objects and advantages of the present invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings, in which:
The structure and aspects of a head assembly of a golf club according to the present invention is applied to all golf clubs by various embodiments. Hereinafter, the head assembly of a golf club according to the preferred embodiment of the present invention and its modifications will be described in detail in conjunction with the accompanying drawings. Although the head assembly of the preferred embodiments of the present invention and the modifications are applied to different kinds of golf clubs, identical reference numerals are assigned to the same head and the elements corresponding to the head.
As shown in the drawings showing only a head H of an iron I, parallel frictional lines S such as engraved lines formed in a face F of the head generate friction to prevent a golf ball from slipping.
The iron I, employing the head assembly of the first embodiment, includes aim guiding channels C1 and C2. The aim guiding channels C1 and C2 take the form of depressed channels near the sides of the face F having a channel such that the distance d between the aim guiding channels C1 and C2 becomes narrow as goes down.
The aim guiding shape G, formed by the colored part Cf and the uncolored parts Nc1 and Nc2, may have a V-shape having an acute angle as shown in
Since the aim guiding shape G provides a high visual perception when impacting a golf ball, the golfer can aim the golf ball and precise striking of the golf ball with the iron I, and the golfer's aim can be mentally stabled and visually guided. Due to the aim guiding shape G, the golfer intend to aim the head H until the golf ball is struck by an impact point formed by the aim guiding shape G, and as a result, the habit of hastily swinging the golf club can be eradicated.
Embodiment 2
The sight is provided in the form of a semispherical or quarter-spherical sight 10 like a golf ball cut into two or four sections as shown in
The sights 10, 11, and 12 are made of a solid steel sphere, stainless steel, or synthetic resin, and are attached to or integrally formed with the iron I. More preferably, the centers of gravity g of the sights 10, 11, and 12 correspond to the center of gravity gh of the head H.
Since the golfer impacts the golf ball B, placed in an impact line L, against the sight without being conscious of the head H of the iron I, due to the sights 10, 11, and 12, the golfer can easily align the impact point of the head H with the golf ball B while keeping mental or visual stable state. Thus, precise impact is conducted and bad posture is naturally corrected.
Embodiment 3
A conventional iron I includes a lower side connected to a head face HF as a lower side of a head H of the iron, contacting the ground when impacting a golf ball, and extended from a neck N.
A plurality of slip lines SL is engraved in a slip area SA adjacent to the neck N of the head H of the iron I.
The slip lines SL, as shown in
In addition to the slip lines SL, like a first modification in
Moreover, like a third modification in
In this embodiment, due to the slip lines SL, the golfer's aim, guiding the golfer's aim, and reduction of friction between the head H and the ground are achieved when swinging the golf club, so that the distance is increased.
Embodiment 4
In this embodiment, a sight 25 is integrally or separately mounted opposite to the face F of the head H of a putter P depicted as an example, guides a golfer's aim, and has a shape, such as a semi-spherical golf ball shape, a quarter-spherical golf ball shape, a solid semi-spherical shape, or the like. The effects of the head assembly of this embodiment are identical to those of the second preferred embodiment.
Embodiment 5
As shown in
The aiming face 30 is a combination of a triangle-shaped aiming mark 31 and equilateral triangle aim guiding marks 32. The triangle-shaped aiming mark 31 is formed at the central portion of the face F, and the equilateral triangular aim guiding marks 32 are formed at the sides of the aiming mark 31. The aiming face 30 is made of a plate or is formed by cutting side margin parts V of the face F of the head H.
Moreover, the head H includes rib-shaped aim guiding flags 40, formed at the upper side of the head H and extending backward by a predetermined extension length L2 and integrally or separately formed with the head H, and an aiming guide 41 taking the form of a protruded line having various shapes.
According to the putter P employing the head assembly of this embodiment, when important swing in the putt swing, such as backswing, a golfer aims along the aiming face 55 and a aim guiding device of the aim guiding flag 50 extending from the aiming face 55 so as to impact a golf ball against the aiming face 55, and as a result, slow impact against the golf ball is conducted and the hasty swing is controlled.
Embodiment 6
The head assembly further includes a sighting line 60 converging to or diverging from an upper reference line L of a face F of a head H of the driver D and having various shapes.
The aim guiding line 60, as shown in
A common aspect of apexes AP of the aim guiding lines 60 is that the center of gravity G of the head H of the driver D is positioned in a moving impact line T.
Moreover, in addition to a single aim guiding line 60 in
A second modification of the sixth preferred embodiment, as shown in
As shown in
The aiming mark M1 has various shapes and is formed by printing and engraving in intaglio or in relief. In this embodiment, the W-shaped aiming mark M1 is depicted as an example by considering the golfer's aim and its direction.
Although all the aiming marks are depicted for illustrative purposes, dotted aiming marks M2 and M3, as shown in the drawing, are selectively formed at different positions such as the position on the center line C aligned with the impact line L of the head H or the position opposite to the aiming mark M1 about the center line C. Of course, even in this case, effects and operation of the dotted aiming marks M2 and M3 are identical to those of the aiming mark M1.
Moreover, although all the aiming marks M1, M2, and M3 are depicted in the drawing for illustrative purposes, instead of the aiming marks M1, M2, and M3, in a first modification of the head assembly in
All aiming marks M4, M5, and M6 having various shapes, such as an approximate W-shape, are depicted in the drawing for illustrative purposes, and are formed in the upper surface CR of the head H of the putter P at the right and left sides of the center line C aligned with the impact direction.
The aiming marks of this embodiment serve as an aim guiding mark for continuously guiding the golfer's aim when impacting the golf ball to enable the golfer to aim. Moreover, the swing trace of the head when backswinging is easily confirmed with naked eye to prevent hasty backswing.
The head assembly having aim guiding function according to the present invention can be applied to various heads of the driver (including a fairway wood), the iron, and the putter, and also applied to the conventional golf club.
A mark for guiding the golfer's aim when impacting a golf ball is provided to enable the golfer to continuously aim the head of a golf club and to increase the direction of impact. Since the trace of backswing is easily confirmed with the naked eye, putting posture and skill of the golfer affected by the mental state of the golfer are enhanced.
Moreover, since the golfer aims when striking the golf ball, the habit of continuously keeping the golfer's aim to the head of a golf club is accustomed to the golfer such that the golfer naturally habituates the careful swing of a golf club.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
