The present invention relates to a golf club. More particularly, the present invention relates to a golf club capable of allowing a user to properly adjust the striking direction and striking impact for a golf ball by presenting a reference line for accurately striking the golf ball, and simultaneously providing an index for checking the exact movement distance and direction of a club head in take-back and striking actions.
BACKGROUND ARTGolf is a sport in which a player strikes a golf ball placed on a field by using a stick-shaped club until the golf ball is put into specific holes, and then the ranking is determined according to the number of strokes.
In general, a golf course has 10 par-four holes, four par-five holes, and four par-three holes. A shot on a green requires delicate skill and high-level skill is required to put a golf ball into a hole having a diameter less than about 11 cm.
A golf club refers to a stick for striking the golf ball. The golf club comprises a club head part for striking a golf ball and a shaft part. The golf club is classified into a wood club, an iron club and a putter according to the shape and material of the head. The wood club, iron club and putter have purposes and functions different from each other.
The wood club is used for sending a golf ball as far as possible, and the iron club is selectively used according to distance. The wood and iron clubs have their own number. The club having number 1 has the longest length. The wood club has a length longer than that of the iron club.
The golf putter is used to finally put the golf ball into the hole in a golf course. The term “putting” denotes an action for rolling a golf ball, which is located adjacently to the hole, on the green to put the golf ball into the hole. The golf putter is a golf club used for putting.
Hereinafter, the problems of the conventional golf club will be described by employing a golf putter as an example of the golf club. The following problems are also applied to a golf club such as an iron club and a wood club.
Referring to
According to the prior art, a reference line 4 is formed on the club head 3 for accurate putting. The reference line 4 serves as a kind of an index by which a user precisely adjusts the striking direction for a golf ball making contact with a striking surface 5. The striking direction for the golf ball matches with the extension line of the reference line 4.
According to the prior art as described above, accurate putting is performed using various reference lines formed on the club head 3 of the golf putter in various methods. However, the reference line provided in the prior art is limited only to the club head 3. Thus, it is difficult for a user to accurately strike a golf ball while watching the reference line 4 because the reference line 4 is far from the user's eye when considering the length of the shaft 2 of the golf putter. Further, since the club head 3 moves in the leftward and rightward directions to strike the golf ball, it is difficult for the user to accurately watch the reference line 4 on the club head 3.
In a putting action, striking impact for the golf ball is also very important as well as the striking direction for the golf ball because the striking impact must be precisely adjusted according to the distance between the golf ball and the hole. The striking impact is dependent on the speed, at which a user moves the golf head 3 to strike the golf ball, and the distance by which the golf head 3 moves in the backward direction when the user moves the golf head 3 in the backward direction after grasping the grip 1 and then moves the golf head 3 in the frontward direction along the same path to strike the golf ball.
At this time, the action in which the user moves the golf head 3 in the backward direction in order to strike the golf ball will be referred to as take-back. The action in which the user moves the golf head 3 in the frontward direction in order to strike the golf ball will be referred to as putting. The putting may be a part of striking for the golf ball.
According to the prior art, the golf putter presents the striking direction for the golf ball using the reference line 4 marked on the club head 3, but does not present an index for estimating the movement distance of the club head 3 having influence on the striking impact for the golf ball. Therefore, a user must intuitively adjust the striking impact.
DISCLOSURE Technical ProblemThe present invention has been made to solve the above problem occurring in the prior art, and an object of the present invention is to provide a golf club capable of allowing a user to properly adjust striking direction and striking impact for a golf ball by presenting a reference line for accurately striking the golf ball, through the shaft structure of the golf club, and simultaneously providing an index for checking the exact movement distance and direction of a club head in take-back and striking actions.
Technical SolutionIn order to accomplish the object of the present invention, there is provided a golf club provided with a shaft, which has a first side surrounded by a grip grasped by a user, and a club head, which is connected to a second side of the shaft to strike a golf ball, the shaft comprising: a shaft body including transparent material; and a guide member inserted into the shaft body and having a specific sectional shape such that the guide member guides horizontal movement of the golf club.
The club head comprises a head reference line included in a striking surface making contact with the golf ball, and the specific sectional shape of the guide member comprises a vertical reference line formed vertically to the head reference line.
Further, the specific sectional shape comprises at least two vertical reference lines spaced apart from each other by a predetermined interval while being parallel to each other.
Furthermore, the specific sectional shape comprises one of a quadrangle, a rectangle, a pentagon, a hexagon, an octagon, a circle and an oval.
Moreover, the specific sectional shape is observed at an uppermost end of the shaft surrounded by the grip.
Preferably, the guide member is painted by a distinguishable color.
More preferably, the color comprises a fluorescent color.
ADVANTAGEOUS EFFECTSThe golf club according to the present invention can allow a user to properly adjust striking direction and striking impact for a golf ball by presenting a reference line for accurately striking the golf ball, and simultaneously providing an index for checking the exact movement distance and direction of a club head in take-back and striking actions.
Hereinafter, exemplary embodiments according to the present invention will be described with reference to the accompanying drawings. A golf putter will be described as an example of a golf club, but the technical scope of the present invention is applied to a golf club such as an iron club and a wood club.
Referring to
The club head 30 comprises a striking surface 31 on which the golf ball is struck, and a head reference line 31a included in the striking surface 31. The head reference line 31a denotes a reference line defined by the outer peripheral portion of the club head 30. Further, a reference line parallel to the striking surface 31 may be additionally formed on the club head 30. In any case, the head reference line 31a is perpendicular to a vertical reference line 22a.
In general, an initial shaft is a steel shaft used in the 19th century. With the development of technology, the steel shaft has been replaced with a shaft including carbon, which has high strength with light weight and elasticity. In general, such a shaft has a function of maximally transferring energy, which is generated in a swing action, to a golf ball, and transferring striking feeling to a golfer when the golf ball is struck by a club head.
The shaft 20 of the golf putter as the golf club according to the present invention performs the typical functions of such a shaft. In addition, the golf putter according to the present invention provides the shaft 20 capable of properly adjusting striking direction and striking impact for a golf ball by presenting a reference line, which is used for accurately striking the golf ball, and simultaneously providing an index used for checking the exact movement distance and direction of a club head in take-back and striking actions.
Referring to
Preferably, the shaft body 21 has material having proper strength and elasticity. In any case, the shaft body 21 must include transparent material to allow the guide member 22 to be observed from an exterior.
The guide member 22 has a specific sectional shape. Preferably, the specific sectional shape is a quadrangle formed by four straight lines as shown in
The vertical reference line 22a is used for adjusting the striking direction for the golf ball, as in the case of the reference line 4 (see
The specific sectional shape may have any shape if the sectional shape includes the vertical reference line used for accurately striking the golf ball. Accordingly, the specific sectional shape may have one of quadrangular, rectangular, pentagonal, hexagonal and octagonal shapes. Further, two or more vertical reference lines 22a may also be spaced apart from each other by a predetermined interval while being parallel to each other.
Since the guide member 22 has a function of allowing a user to psychologically and stably feel if the shaft of the golf putter moves in the desired direction according to the striking direction for the golf ball when the user moves the golf putter, the guide member 22 may have a circular or oval sectional shape painted in a distinguishable color. When the guide member 22 has a circular or oval sectional shape, a psychological reference line may be set using the guide member 22 formed below the grip 10 instead of providing the vertical reference line 22a through the sectional shape. The psychological reference line is a special feeling line of only a user formed when the user uses the golf putter as the golf club according to the present invention several times.

Further, when the user watches the golf ball 60, the guide member 22 appears by a predetermined length. Since the guide member 22 has the distinguishable color, the user can clearly recognize the length of the guide member 22. Accordingly, the guide member 22 can serve as a reference index used for adjusting the club head 30 to an accurate position.
Referring to
Meanwhile, since the striking impact for the golf ball 60 is increased as the psychological reference line formed by the guide member 22 becomes longer, the user can sensitively and properly maintain the striking impact according to the distance between the hole 50 (see

The guide member 22 of the present invention also provides the psychological reference line as described above. In order to reveal the function of the guide member 22′ the shaft body 21 has a sectional shape the same as that of the guide member 22 according to another embodiment of the present invention.
Referring to
If the situation requires, the shaft can be formed using only the guide member 22 without the transparent shaft body 21′ In such a case, a stronger visual after-image can be provided to the user due to the special color of the guide member 22′
Accordingly, only the guide member 22 can form the shaft of the golf club according to the embodiment of the present invention. Here, the shaft comprises the shaft body 21 and the guide member 22′ However, the shaft body 21 is distinguished from the guide member 22 only for convenience of description. That is, the shaft body 21 can be integrally formed with the guide member 22′
In any case, when the user performs the take-back, the guide member 22′ has influence on the psychology of the user by providing the user with a visual after-image along a predetermined trajectory, so that the guide member 22? provides the user with a predetermined psychological reference line.
Further, the technical scope of the present invention can be applied to an iron club and a wood club, as well as the golf putter as the golf club as described above.
