Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates generally to golf putter clubs, and more specifically to a wrist that is forward breaking while maintaining a precise line of sight during putting. The present invention relates to a putter club for golf that can prevent

[0002]

BACKGROUND OF THE INVENTION Bending your wrist forward during putting is also known as YIPS.
Not desirable. YIPS is bending of the wrist forward and the club head moves to the front of the hand when or immediately after hitting the ball. If your wrist bends in this way during putting, you will lose control of putting.

Further, in a conventional putter in which the shaft is not tilted forward at all, the shaft is connected to the putter head at an angle of 90 degrees. As a result, there is a desired line of sight, and the putting stroke tends to coincide with a straight line from the rear to the front along the desired line of sight. However, it has been found by the inventor that when the shaft is tilted forward of the putter head,
The putter head appears to the golfer to be angled inward to the left (for a right-handed golfer) or to the right (for a left-handed golfer) from the desired putting stroke line. As a result, golfers tend to make corrections, with a right-handed golfer hitting the ball to the right of the desired putting line and a left-handed golfer hitting the ball to the left of the desired putting line.

This tendency is remarkable when the upper surface of the putting head is lowered rearward in order to give the putter an aerodynamic appearance, and when the upper surface of the putter head has a horizontal surface, that is, the putter head. Is particularly problematic when addressed to the ball as compared to having a surface parallel to the ground. In such a case, right-handed golfers tend to hit the ball aiming for the right side of the desired putting line.

[0005]

The following objects and advantages are achieved by the golf putter club of the present invention. (a) YIPS can be prevented. (b) Can make a truly straight pendulum stroke. (c) Even when the shaft is tilted forward of the putter head, the upper surface of the putter head should be higher at the rear.
By creating the upper surface of the putter head, it is possible to match the line of sight and the swing with a desired putting line. (d) The shaft may be aligned with the golfer's leading arm and wrist. (e) Only the front part of the club head of the putter contacts the ground. (f) The golfer's weight is not applied to the golf club.

The above advantages are obtained by providing the following golf putter clubs. (a) Conventional length. (b) It can be used in any putting style and gives the golfer free movement. (c) Can be used on any type of Patting Grip. (d) The golfer should be able to move the putter with his back hand at the end of the stroke so that he can swing naturally. (e) The lower end of the shaft may be directly connected to the club head or hosel, provided the putter complies with USGA regulations.

The above and other objects, features and advantages of the present invention will be readily apparent from the following detailed description with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION To solve this problem, FIG.
It will be described with reference to FIGS. According to an embodiment of the present invention, golf putter club (210) includes a generally T-shaped club head (212). Club heads (212) for natural heel and toe balance
Although a T-shape is preferred, the shape of club head 212 is not limited to a T-shape and may be any other suitable shape.

In the illustrated embodiment, the club head (21
2) has a ball hitting part (214) in the front part, and a shaft connecting part (216) is connected to the rear part at a right angle to the ball hitting part (214), and the club head (212) has a T-shape as described above. It is formed. In addition,
The rear shaft connection (216) is parallel to the golfer's eyes and serves as an aid in aiming the putt.

As best shown in FIGS. 4 and 5,
The front hitting portion (214) has a substantially rectangular plan view,
The lower end portion (214a) is slightly arcuate, has a curvature defined by a circle having a radius of about 7 inches, and forms a substantially rectangular putting face (218). However, it should be understood that the shape may be any other suitable shape. An example of an appropriate size is the front hitting section
The upper surface (220) of (214) has a side-to-side length of 3.3 inches, a front and rear width of 0.6 inches, and a front hitting portion.
The same applies to the bottom surface (222) of (214). The front putting face (218) has a height at its center of 1 inch.
The shape and dimensions of the rear face (224) of the front hitting portion (214) are
Although substantially the same as the front putting face 218, the invention is not so limited.

The rear shaft connection (216) is generally rectangular in shape, but its bottom surface (226) is upwardly tapered from the front end (228) to the rear end (230). As shown in FIGS. 3 and 6, the portion (229) of the front end portion (228) of the bottom surface (226) is flat and flush with the bottom surface (222) of the front hitting portion (214). There is. The shape of the portion (229) is a semi-oval shape, but is not limited to this. Thus, when the putter club (210) is placed on the ground, the rear end portion (230) of the bottom surface (226) is located higher than the front end portion (228) of the bottom surface (226). The reason will be better understood from the description below. As an example, the bottom surface has a radius of 8 inches (R8) and then a radius of 0.8 inches (R), as shown in FIG.
0.8) circle, followed by a radius of 0.125 inches (R0.12)
It can be bent upward from the portion (229) along the circle of 5). Although the bottom surface shown is sloped, it will be appreciated that any structure that allows the rear of the club head to be higher than the front of the club will do.

In the preferred embodiment, the rear shaft connection (216) has a front to rear distance of 2.17 inches and a side to side width of 0.874 inches.

In the putter club (210), the shaft (232) is connected to the upper surface (234) of the rear connecting portion (216). shaft
(232) is a conventional shaft and can be connected to the shaft (216) in the same manner as before. For example,
The shaft (232) is attached to the rear shaft connection (21
It can be welded into the hole (233) in the upper surface (234) of 6).
Alternatively, a hosel (not shown) for connecting the shaft (232) can be provided. The shaft (232) is preferably connected with its axis 0.55 inches from the trailing edge of the upper surface of the rear shaft connection (216). This position is slightly separated from the longer edge of the rear shaft connection (216) closest to the golfer.

The length of shaft 232 is about 37 inches or less, similar to conventional putter clubs, but is preferably greater than about 33 inches.

The shaft (232) is inclined at an angle Y laterally from a vertical line. The angle Y is generally larger than 10 degrees according to the regulations of the USGA regulation, and is about 1
A range of 5 to 22 degrees is desirable, with about 20 degrees being more desirable, as best shown in FIGS.

As best shown in FIG. 3, the shaft
The (232) is connected to the upper surface of the rear shaft connecting portion (216) so as to have a front angle Z and is inclined at an angle of about 8 degrees or more with respect to the vertical line. This angle is about 8 ~
It is preferably in the range of 10 degrees, more preferably about 9 degrees. When the angle is out of this range, the effect of YIPS prevention is not so good. With such a shape, a loft can be provided, but there is no loft on the front putting face (218).

Due to the above structure, the putter club (210) provides improved putting, especially because the shaft has the maximum length and is connected at an angle of 8 to 10 degrees in the front-rear direction.

In particular, due to having the structure of FIGS. 1-6, the golfer's hand has a front putting face (218).
Maintained about 1.5 inches forward from the shaft (23
2) is always on the same line as the golfer's leading arm until the putting is finished. As a result, the golfer's wrist does not break during putting, so YIPS
Is prevented. As a result, the golf player can maintain the control state until putting is completed. If the forward angle of the shaft 232 is less than about 8 degrees, then YIPS cannot be prevented, resulting in a wrist break during putting.

In addition, the golfer's hand is maintained approximately 1.5 inches in front of the front putting face (218) so that the golfer's weight does not rest on the club. this is,
This means that the swing can be performed more smoothly, and has the additional effect of preventing a break in the wrist. In the case of a conventional putter, the golfer's weight is applied to the shaft and the putting head is pushed down.

Furthermore, using a conventional shaft having a length of about 37 inches or less, the club head (212) is hit by a usual hitting method until the putter club (210) is released from control after hitting the ball. You can follow a few inches or more. It can be struck in a natural way and does not force the body to deform. With such a structure, the latter hand can be easily released after hitting the ball in a naturally flowing motion.

As described above, according to the present invention, since the stroke of the true pendulum movement is obtained, the club head (212) moves along a straight line, I will not be bound. Furthermore, during putting, the shoulders are horizontal and a true pendulum stroke can be achieved, and a line of sight for it can be well defined.

This is a hand-to-head lug.
all kinds of putting styles, including ead lag)
And any putting grip means that it can be done with the putter of the invention, without any restrictions.

As mentioned above, the bottom surface (226) is inclined upward and backward. As a result, only the bottom surface (222) of the front hitting portion (214) and the part (229) of the front end portion (228) of the bottom surface (226) do not come into contact with the ground during the putting setup and during the actual putting. Are in contact. In the construction of the present invention, it is important that the hand is approximately 1.5 inches in front of the putting face (218), so that only the front of the club head (212) contacts the ground, resulting in a smoother stroke. Can be surely obtained. This is especially important in the present invention where the shaft is connected to the rear of the club head, and whatever weight is exerted on the putter, as shown in FIG. Will act on the front of the club head.

As an important point of the present invention, the entire upper surface of the club head (212) is tilted upwards from its front part to its rear part, so that the shaft (232) has its upper surface (23).
4) to form an angle in the range of about 85 to 90 degrees, preferably in the range of about 88 to 90 degrees (Fig. 3).
reference). In this specification, this range and its equivalent range are
It is defined as "substantially perpendicular". For example, the equal range includes an angle of 91 degrees. In the most preferred embodiment, as shown in FIG. 3, when the club head (212) is addressed to the ball, the top surface of the club head (212) is tilted upwardly with respect to a horizontal or ground surface by about 7 degrees, The shaft (232) is
It is tilted 9 degrees forward with respect to the vertical. As a result, the angle between the shaft (232) and the upper surface (234) is 88 degrees.

In the case of a right-handed golfer, the problem that the club head looks inward to the left from the desired putting line, and in the case of a left-handed golfer, the problem that the club head looks inward to the right from the desired putting line is This occurs when the top of the head has no upward slope and the shaft is sloped forward, but these are eliminated by angling the top of the club head (212) from front to back. You can As a result, in the case of a right-handed golfer, there is no tendency to correct and hit the hole to the right of the desired putting line, and in the case of left-handed golfers, there is no tendency to correct and hit the ball to the left of the desired putting line. .

For conventional shafts, when the shaft is tilted forward of the club head, the club head (212)
It will be appreciated that the problems encountered when looking at the angle can be eliminated by having the shaft (232) in a generally perpendicular relationship to the club head (212). In fact, the putters up to now are exactly the opposite of the present invention, they have no bevel, and the top of the club head is beveled to the opposite side for aerodynamic appearance, i.e. from front to back. And even tilt it downwards.

As described above, in the case of the embodiments shown in FIGS. 1 to 6, the line of sight and the obtained swing are on the desired putting line even when the shaft is tilted forward of the putter head.

Although the upward inclination angle shown in the figure is 7 degrees, it is assumed that this inclination angle varies depending on the forward inclination angle Z of the shaft (232), so that the shaft can be made to have a substantially orthogonal relationship. Make sure your line of sight and swing match the desired putting line, even when leaning forward of the putter head.

In the illustrated embodiment, the upward slope of the upper surface of the club head (212) is along its entire length and, in practice, the front striking portion (214) and the rear shaft connecting portion (216). It is along, but not limited to, both top surfaces. Even when the shaft is tilted forward of the putter head, if the majority of the upper surface of the club head (212) is tilted upward, the line of sight and swing can be sufficiently aligned with the desired putting line. However, for maximum effect, the slope should be along the entire top surface of the club head (212). For example, shaft
The connection between (232) and the club head (212) may be interrupted and then leveled, or it may be tilted downward from the connection position toward the rear.

The club head (212) is made of different materials. In particular, the bottom (28) of the rear shaft connection (216)
0) and the main part (282) of the front hitting part (214) are formed by an integral piece of aluminum. Rear shaft connection (216)
The upper part (284) of the is formed from brass, and the upper part (284) extends to the front putting face (218) of the club head (212), which allows the main part (282) of the front striking part (214) to be formed. It extends through a hollow (286) that is hollowed out. Upper part (284)
The upper surface of the is angled upwards and backwards from the front putting face (218) to the rear of the club head (212) at the aforementioned 7 degree angle. Then, the upper surface of the front end portion of the top portion (284) has a common plane with the upper surface of the main portion (282) of the front hitting portion (214), and along the entire upper surface of the club head (212), the upper surface and It is tilted backward by 7 degrees.

Further, a cylindrical brass insert (286) is loaded in a recess (288) cut into the rear face (224) of the front striking portion (214). insert
(286) preferably has a diameter of 0.610 inches.

The use of brass for the top portion (284) and insert (286) reduces the weight of the putter head (212) and provides the desired weight and balance characteristics.

Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the embodiments themselves, and those skilled in the art can define the scope of the claims. Various modifications may be made without departing from the scope or spirit of the invention as made.
