Description

Golf club with a bending grip {golf club having a bended grip portion}

The present invention relates to a golf club having a bending grip. In particular it relates to a golf club in which the grip portion is bent by the freeback angle with respect to the straight portion of the shaft.

Golf players practice a lot of swing in order to be able to send the ball exactly the distance they want in the direction you want. However, it is very difficult to keep the address and swing constant.

Many amateur golf players are striving to align the ball precisely to the address to hit the golf ball accurately, the swing form of the golf club, and the sweet spot of the clubhead to improve performance. Repeated many times, but the results are insignificant.

The trajectory of the flying ball has a great influence on the direction and speed of movement of the clubhead and the weight and angle of the clubhead face when the clubhead meets the ball. In many cases, a slice shot or a hook shot prevents the golf ball from flying in the desired direction. In order to make the club head swing track ideal, much attention is paid to the address and backswing process. When the club face hits the ball at right angles to the aspherical direction, the ball does not spin freely, so it does not slice or hook and flies in a constant direction.

To do that, it's important for the player to practice a lot, but it's also important to make sure that the golf club fits into their physical condition and swing form.

However, since most golf clubs are made as ready-made products in the factory, there are not many types of players to choose from, and it is difficult to find out which standard is suitable especially for beginners, and even though the power used as a beginner does not fit as the power increases. It may be done. Golf clubs produce club sets that vary lie angle, face angle, loft angle, etc. as well as club weight and shaft length to suit the physique, but not all standard sizes are available for testing. Difficult to choose what to build and swing.

Loft is the lying angle of the face face to the shaft centerline, the longer the club (lower numbered club), the smaller the loft and the larger the shorter club (wedge, etc.). The lie angle is the angle between the head's sole and the shaft when viewed from the front of the face and is closely related to the shaft length for the player's body type. The face angle refers to the angle that the face of the head makes with respect to the shaft axis and is usually expressed as being open or closed. As such, the lie angle and face angle of the golf club head have a great influence on the distance and direction of the ball, and they must be designed and manufactured to meet different physical conditions and dispositions. In practice, however, many amateur players find it difficult to find golf clubs that fit their physical condition. Even if you choose a golf club that fits your physique, it is very difficult for beginners to keep a constant `` Tateaway ''. During take away, wrist movement is very important because it affects a lot of swings later, but it is time-consuming and difficult for beginners to master. In addition, the shaft of the golf club is straight, and in order to hold it with both hands and set it downward as inclined as the lie angle, one shoulder should come down than the other shoulder, so the triangle made by the hands and both shoulders is incomplete and isosceles It is a triangle crushed more than a triangle, and in this state, the take away should be taken for a certain distance or angle for the backswing. Most of the wrists are pre-swinged swings, making it difficult to hit the correct swing.

Reaching the third point to back at the right address is actually a very difficult and complicated but important operation. There is a need to create a new golf swing paradigm that can create an accurate swing plan by minimizing the unnecessary and unnecessary rotation and caulking of both hands to address, back and impact.

A golf club that can make new golf swings that can easily and accurately address, back, and impact by creating an accurate swing plan by minimizing the unnecessary and unnecessary rotation and caulking of both hands to address, back and impact in golf. It is a problem of the present invention to provide.

The present invention is to provide a golf club having a bending grip that can give a sense of address stability by varying the lie angle (face angle) and face (face angle) according to the user's physical condition.

The present invention is to provide a golf club that allows a beginner to easily learn the golf swing and to send the ball accurately in the aspheric direction at the time of hitting.

The present invention is to provide a golf club that can easily find the specifications of the golf club suitable for their physique and swing form.

The present invention is to provide a golf club that can hit the golf ball differently from the conventional golf swing theory.

According to the present invention, the golf club shaft has a straight portion and a grip portion bent at an arbitrary angle (hereinafter referred to as a "bending grip"), and the bending grip portion is predetermined in a direction in which the lie angle and the face angle are smaller than the straight portion of the shaft. The goal is to provide a golf club that is bent by the angle of the angle (hereinafter referred to as the "freeback angle").

The pre-back angle is to be bent in the range of 5 to 40 degrees with respect to the axis of the club shaft in the direction in which the lie angle and face angle are reduced.

The golf club shaft of the present invention consists of a straight portion attached to the club head and a bending grip bent at any angle.

The bending grip is coupled to the straight portion of the shaft and bent by the freeback angle in the direction of decreasing the lie angle and the face angle. The pre-back angle is bent in the range of 5 to 40 degrees with respect to the axis of the club shaft in the direction in which the lie angle and the face angle become smaller.

Bending in the direction of decreasing lie angle can reduce the role of wrist caulking (movement of the wrist up and down) among freeback angles, and bending in the direction of decreasing face angle is bending toward the target. Unnecessary turning can be reduced. In addition, swing plans that are difficult to learn in the swing can be reached easily and accurately, and starting with the correct posture from the address, the correct and correct backswing top position can be easily taken to make a powerful impact.

The length of the bending grip should preferably be within 25 cm of its end.

The straight portion and the bending grip are integrally formed at a predetermined angle, or the two shafts are attached by welding or the like, or are joined using a separate coupling means.

The coupling means may be a coupling means having a structure such as a universal joint, in which two pin coupling means are connected in series so that two shafts are connected by pins to be fixed at an angle to each other. One may use a pin coupling means, and one may be coupled on the same shaft, but may use a rotary shaft coupling means that can be fixed to the shaft so that the shaft can be rotated at any angle to each other. The rotating shaft coupling means uses what can be fixed at a predetermined position using already known devices such as a spline shaft coupling device.

The pin coupling means rotates at an arbitrary angle, such as a toothed pin coupling means having radial teeth formed on the coupling portion so as to bend and fix two axes at an arbitrary angle, and one axis of the toothed pin coupling means and a spline shaft coupling device. It can be configured as a rotating shaft coupling means to be fixed to the linear portion of the shaft.

Golf clubs having such a coupling means can be used for practice or swing analysis to find a freeback angle for each player, and can be used as a golf club for actual play. In addition, the coupling means is formed with an angle display to know how much the angle is bent relative to the axis.

When the golf club of the present invention is used, the shaft of the golf club is bent by the handle portion because the handle portion is bent, the degree that one shoulder is lower than the other shoulder is lower than the conventional golf clubs, and thus the hands and two shoulders The resulting triangles are less imperfection than conventional and the wrist is set up with some degree of pre-cocked in advance, thus preventing misses in the early stages of the swing.

Because of the bending grip, the lie angle is bent to reduce the role of wrist caulking (movement of the wrist up and down), and the angle of the face is bent to reduce the unnecessary angle of the hand, right and left of the hand. Can be reduced. In addition, swing plans that are difficult to learn in the swing can be reached easily and accurately, starting with the correct posture from the address (correct address), the posture can be easily brought to the correct and correct backswing top for powerful impact. .

In addition, the effect of the banding grip is that the hands are already positioned at a third point that amateurs can't take accurately from the address, so the new swing form is easy to achieve. Therefore, unnecessary rotation of the hand movement and caulking are unnecessary, and the connection operation from the exact start of the backswing can proceed.

Among the many standard products produced in the factory, even if you do not find and choose a golf club that suits your body type and swing form, you can find a club, lie angle and club face angle that fits you with one golf club. The choice of club is very convenient for beginners, and it can be useful for experienced people to analyze and adjust their swing form. So it can contribute greatly to the popularization of difficult golf play.

You can easily take away when practicing the swing form, which will simplify the overall swing, thus preventing the blow miss. And beginners can save a lot of time learning golf.

Specific embodiments will be described with reference to the drawings.

The golf club shaft of the present invention has a straight portion 20 attached to the club head 10 and a bending grip 21 bent at any angle. The bending grip 21 is coupled to the straight portion 20 so as to be bent by the pre-back angle PR in a direction in which the lie angle is smaller and the face angle is smaller.

)을 뺀 것과 같다.As shown in FIG. 1, the coupling relationship between the club head and the shaft is defined as the angle of the shaft 20 formed with the horizontal plane when the lower surface of the sole member, which is the bottom surface of the club head, is placed parallel to the horizontal plane.

), And the angle that the face surface 11 makes with the vertical surface is called the loft angle (

When the shaft 20 is raised by the lie angle and the horizontal projection line of the shaft is parallel to the Y axis, and the sole member of the club head is placed parallel to the horizontal surface (XX), the angle created by the face surface and the shaft axis is faced. It is called angle. This face angle is an angle at 180 degrees (

Is the same as minus).

As shown in FIG. 1, the pre-back angle PR is a three-dimensional angle in which the bending grip 21 is bent by a predetermined angle with respect to the straight portion 20, and is bent to the left from the axis of the straight portion 20 in FIG. 2. It is set in the range that eventually the lie angle and / or face angle becomes 5 to 40 degrees smaller. The bending grip 21, which extends from the end of the shaft to the bent portion, preferably has a length within 25 cm.

The straight portion and the bending grip may be molded in a bent state at an arbitrary angle, or may use a coupling means so as to be fixed at an arbitrary angle.

An example of a coupling means is shown in FIG. 3, which comprises a pin coupling means 40, 41, 42 and a pin coupling means configured so that two shafts 40 and 50 axes can be engaged at an arbitrary angle. It consists of rotary coupling means 50, 46, 47 which are rotated at any angle and are coupled to the straight portion 47 of the shaft while maintaining the same axis as one axis (e.g., the axis of shaft 50).

Instead of the rotary coupling means, two sets of pin coupling means may be used in a right angle with each other. That is, one member (for example 40) coupled to the bending grip and the straight portion may be fixedly coupled to each other, and the intermediate members to couple them to the pins 42 may cross each other at right angles even though the pins may be different from each other. This structure is a coupling means having a structure such as a universal joint.

Rotating shaft coupling means may be used to combine the rigid angle by a predetermined angle using a spline shaft coupling device. Such couplings should be able to be securely fastened using locking devices (eg tightening screws) that can be reliably fixed once the angle has been determined.

The pin coupling means uses a toothed pin coupling means in which radial teeth 45 are formed on the coupling portion so as to bend and fix the two shafts at an arbitrary angle, thereby increasing certainty in the angle fixing.

Although not directly shown in FIG. 3, the reference point and the angle are displayed on the straight portion 47 and the rotation coupling means 50 so as to know how many degrees the angle is rotated at the reference point. The angle display is formed so that it can be. In addition, the pin coupling means 50 also has a reference point and an angle display portion for indicating the relationship with the axis around the saw 45, so that it is possible to know how much the angle is bent on the same axis. Thus, it is easy to see how many degrees are bent in the direction of the clubface and how many degrees are bent in the lie angle. Such angle indicators may use techniques already known in the gauge field.

When address set-up to the golf club as shown in Figs. 1 and 2, the illustrated golf club is a right-handed club, and when the face surface 11 is aligned in the aspheric direction, the left and right hand holding the bending grip 21 are conventionally known. The height of the grip is reduced than the straight shaft of, so it is not necessary to lower one shoulder much, which makes the grip easier. And since the wrist is already in the take away direction and the swing is made at the same angle at the moment of impact, the deviation may be less at the batting moment.

This is because it's much easier to pull your hands with one hand and push with one hand than with two hands together. This is because the muscles of the arm are much developed in the direction of lifting or lowering, and the muscles that give strength to the left and right are relatively less developed.

Golf club of the present invention is also easy to find a freeback angle for the player. This is because you can find a sense by adjusting the coupling means while taking shots in various combinations. So you could mass-produce the shaft with your favorite freeback angle. The present invention will be applied to the putting club as well as the driver or the iron club will see a good effect, and also many effects are expected in the pitching club and sand club.
