Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an improvement of a golf putter club.

[0002]

[Prior art]

 Generally, a putter club for golf is configured by attaching a metal head body to the tip of a club shaft, forming a hitting surface (face) directed vertically in one side of the head body, and forming a center of the hitting surface. A sweet spot is formed in the part.

[0003]

[Problems to be solved by the present invention]

 It is important for this type of putter club to be able to accurately recognize the swing direction of the head body in order to swing the club straight, to be able to visually recognize the position of the sweet spot during the swing, and to hit the ball. It is possible to recognize the presence or absence of rotational blurring at the moment when the head body rotates. Conventionally, in order to achieve the above object, a center line parallel to an imaginary center line passing through the sweet spot is displayed on a part of the upper surface of the head body. The center line drawn along the width (thickness) direction of the head body is useful for recognizing the position of the sweet spot due to its short length. It has little help in determining whether or not there is rotational blur. Therefore, it is possible to accurately determine whether the cause of the failure to hit the ball as desired is whether the swing direction of the head body is incorrect, the rotation of the head body at the time of hitting, or the green undulation. Can not. This is very difficult for beginners as well as skilled people to recognize.

The present invention has been made in view of the above points, and an object of the present invention is to provide a golf putter club in which the probability of cup-in can be significantly improved by simple improvement. .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

<A> Putter Club as a Prerequisite FIG. 1 to FIG. 3 show an example of a putter club 1 according to the present invention. The putter club 1 is a known club in which a head body 3 is attached to a tip of a club shaft 2, and a hitting surface 4 is formed on one side of the head body 3. On the upper surface of the head main body 3, a center line 5 parallel to a virtual center line passing through the sweet spot is written in the width direction of the head main body 3.

<B> Guide Rod In the present invention, one guide rod 6 is attached to the back side of the head body 3. The guide bar 6 is mounted on the back side of the head body 3 in parallel with the center line 5, but is preferably mounted on an extension of the virtual center line passing through the sweet spot. The present invention does not require the display of the center line 5 as an essential requirement. The guide rod 6 has at least a function as a mark of a striking direction for recognizing a striking direction, a function as a mark for swinging the head body 3 in a straight line, and a function of a rotational shake of the head body 3 at the moment of hitting a ball. Since it has the function of confirming the presence or absence, the overall length of the head body 3 is more advantageous as the length of the rearward projection of the head body 3 is longer. About 15 cm is enough. Further, since the guide rod 6 is visually observed on the turf, a color that is easy to see may be applied, or a glossy metal color may be used as it is.

<C> Guide Rod Attaching Structure This embodiment shows a case where the guide rod 6 is configured to be detachable. The attachment structure of the guide rod 6 will be described with reference to FIG. 3. The fixed cylinder 7 is fixed to the back surface of the striking surface 4 constituting the head body 3 by press-fitting, brazing, screwing, or the like. Rubber O-rings 8 and 8 are externally attached and fixed to one end, and the guide rod 6 can be press-fitted into the fixed cylinder 7 by utilizing the elasticity of the O-rings 8 and 8. Although not shown, the guide rod 6 may be detachably attached directly to the back surface of the hitting surface 3 without using the fixed cylinder 7. A screwing means is suitable as the detachable structure. The point is that the guide rod 6 may be mounted on the rear side of the striking surface 4 at a right angle to the striking surface 4.

[0010]

[Action]

 Next, a method of using the putter club for golf will be described.

<A> Attaching / Detaching Operation of Guide Rod The guide rod 6 can be easily attached to the head main body 3 simply by inserting one end of the guide rod 6 into the fixed cylinder 7. Since the O-ring 8 is pressed against the fixed cylinder 7 by the elasticity of the O-ring 8, it does not easily come off. When the putter club 1 is not used, the guide rod 6 is removed from the head body 3 by a pulling operation, and the putter club 1 is stored in the golf bag in a normal state.

<B> Action of Guide Rod During Putting As shown in FIG. 2, the head body 3 of the putter club 1 is positioned immediately before the ball 9, and the striking surface 4 is adjusted at right angles to the striking direction. In conventional clubs, it is extremely difficult to orient the hitting surface 4 accurately, and skill is required. In the present invention, the hitting surface 4 can be directed at right angles to the hitting direction by simply adjusting the guide rod 6 projecting from the back of the head body 3 to the hitting direction. Does not require skill.

Then, as shown by the arrow A, the back swing is performed linearly in the extension direction of the guide bar 6 while visually observing the guide bar 6. During backswing, pay attention to the guide rod 6 swinging sideways. This is because touching the guide bar 6 sideways means displacement of the direction of the striking surface 4.

Then, the head body 3 swings in the direction of arrow B while paying attention to the lateral contact of the guide bar 6. Also in this case, the guide rod 6 is swung visually and linearly so that the hitting direction coincides with the guide rod 6.

While visually observing the guide rod 6, the hitting position and the hitting direction of the ball 9 are confirmed and the ball 9 is swung. At the moment when the ball 9 is hit with the hitting surface 4, it is checked whether the guide bar 6 touches the side. This is to determine whether the hit ball 9 moves in an unexpected direction due to the rotational shake of the head body 3 at the time of hitting. It is very difficult to judge whether or not the head body 3 is rotationally shaken at the time of hitting based on the change of the hitting surface 4. Then, the guide rod 6 appears as a lateral runout (see the guide rod 6 shown by a two-dot chain line in FIG. 2). Therefore, it is possible to easily and accurately grasp the presence / absence of the blur of the hitting surface 4 from the presence / absence of the lateral deflection of the guide rod 6. As described above, the guide bar 6 functions as a pointer in the swing direction when swinging, and also functions as a pointer for confirming whether or not the head main body 3 is shaken when hit.

[0016]

Second Embodiment In the first embodiment, the case where the guide rod 6 is configured to be detachable is described. However, even if the guide rod 6 is fixed to the head body 3 by welding, brazing, or the like, the guide rod 6 cannot be separated. Good.

The guide rod 6 may have a length equal to or less than the width of the head body 3 without protruding from the head body 3. With this configuration, even if the guide bar 6 is attached, it does not hinder the storing and carrying of the putter club.

In some cases, a separate large-diameter cylinder (not shown) is provided on the small-diameter guide rod 6 so as not to easily come off, and the large-diameter outer cylinder is used as a pointer.

[0019]

[Effect of the invention]

 Since the present invention has been described above, the following effects can be obtained. <A> By simply swinging while visually observing the guide rod provided on the head body, not only can the ball strike direction be accurately recognized, but also the blurring at the time of impact can be accurately recognized. Therefore, the probability of cup-in is significantly improved as compared with a conventional putter club. <B> Just by looking at the guide rod, the direction of the striking surface, the direction of the swing, and the like can be accurately grasped, so that the correction can be easily performed. In other words, it is not only possible to accurately determine the cause of the mispat at the driving range or on this course, but it is also easy to correct it. <C> By making the guide rod detachable, it can be removed and stored in a golf bag in the form of a normal putter club when not in use, and does not hinder storage or transportation. The guide rod can be attached and detached as needed, so that one putter club can be used in two ways.
