Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a golf putter, which is applicable for striking a long putt in the areas beyond the golf course such as the rough.

[0003] 2. Description of the Related Art

[0004] In general, a golf club is composed of a club stick and a club head, wherein the club stick at its upper end further comprises a handle for the golfer to grip; and the club head is divided into different types and shapes such as wooden club head, iron club head, and putter head according to the application of the striking. Since the wooden club head has better flexibility, therefore it is generally used for long-distance driving. Most of the iron club heads are made of alloys or soft steel materials; although these materials have a better rigidity, a lower center of gravity, and a flexibility lower than the wooden club head, yet the iron club head is generally used for short-distance or mid-distance stroke. Furthermore, the design with special inclination for the stroke is very suitable for striking the golf ball in various angles and in the poor landform conditions such as in the sand trap and rough. The putter head is generally made of alloys or soft steel materials as well, and generally used for short-distance putt on the green.

[0005] In FIG. 3, the structure of a wooden driver in accordance with a prior art shows that there is a distance L between the center of the striking surface Z of a club head X and the root of the neck section Y, and the neck section Y is coupled to the position of the grip. Therefore, when the golfer grips the handle to strike the golf ball, the neck section is the point of action, and the point of contact on the striking surface Z is the point of reaction. The distance between the point of action and the point of reaction forms a moment of force, and such moment will interfere with the force exerted by the golfer, so that the club head may shake and affect the accuracy of striking direction, particularly in the rough areas adjacent to the golf course. The golfer usually needs to putt according to actual needs, and beginners may use the wooden club and try to strike the ball out of the rough. However, it is unable to accurately control the magnitude of force, and results in a poor stroke and imperceptibly increases the number of strokes. Furthermore, the height of an end of the neck section Y coupled to traditional club head is smaller than the other end, causing imbalance to the center of gravity, or making it difficult for the beginners to control the force and skill of striking the golf ball.

[0006] Furthermore, since the design for the striking surface of a traditional golf putter is almost vertical, therefore it is only applicable for short-distance putt on the even green. To handle a golf ball fallen into the rough area adjacent to the golf course, putt is not suitable, but No. 3 or No. 5 wooden club may be used for the striking instead. However, such way of striking is difficult for the amateur to get a good result, because unlike professional players, ordinary golfers are unable to have long-hour practice in their backyards or golf courses. Therefore, in some matches, ordinary golfer may use No. 3 or No. 5 wooden club to strike the ball and usually result in poor results. However, the design of the putter in accordance with the present invention gives rise to unexpected results after some practice.

SUMMARY OF THE INVENTION

[0007] The primary objective of the present invention is to overcome the difficulty of controlling the stability of the club head while the golfer strikes the golf ball, and it thus overcomes the shortcoming of not able to control the accuracy of the striking direction.

[0008] The secondary objective of the present invention is to overcome the issue that the club head of a traditional putter is not suitable for striking the golf ball in the rough area, uneven surface, or even the sand strap.

[0009] The first technical measure taken by the present invention is to have an evener striking surface for the design of the club head of the putter, and the central axis of the neck section of the club head and the position of the center of gravity of the club head lie on the same straight line, so that the golfer can have a better control on the force of striking the golf ball.

[0010] The second technical measure taken by the present invention is to keep the included angle between the central axis of the neck section of the club head and the vertical line of the center of gravity of the club head within 40°˜50°, so that the golfer can hold the club easier and thus control the force of striking the golf ball.

[0011] The third technical measure taken by the present invention is to keep the included angle between the striking surface and the vertical line within 22°˜28°, so that the golf ball fallen into an uneven ground, rough area, or sand pit far away from the golf course can be stricken back into the golf course. The direction of the striking ball due to the unevenness of the rough will not be changed easily.

[0012] Compared with the structure of traditional club head, the present invention enables the beginner to control the force of striking a golf ball from a rough area after a short time of practice, and the grip of the club complies with the ergonomic requirements, and it thus increases the accuracy of striking the golf ball.

[0013] The putter of the present invention provides a better chance of striking the golf ball out of an uneven ground or even a sand trap back into the golf course, and gives a better effect for the long putt.

[0014] To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, in which:

[0016] FIG. 1 is a front-view diagram of the putter structure of the present invention.

[0017] FIG. 2 is a side-view diagram of the putter structure of the present invention.

[0018] FIG. 3 is a front-view diagram of a prior-art putter structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Refer to FIG. 1 for the front-view diagram of the club head of the putter of the present invention. In the figure, we can see that the club head 1 of the present invention comprising an even striking surface 11. In other words, the height H at the front end of the club head 1 is close to the height h at the rear end of the club head 1, so that the change of shape at the periphery of the club head 1 tends to slow down; and an area with a plurality of stripes in the front side of the club head 1 is the striking surface 11, and the position of the center of gravity of the club head 1 is commonly called “Sweetheart”, meaning that we will get the best shot if we hit the golf ball at this point. The present invention will integrally couple the handle of the neck section 13 with the upper section of the stick 1, and the central axis of the neck section and the center of gravity of the club head lie on the same line. Therefore, when the golfer holds the club by hands, the golfer will have the feeling of integrating with the club as one, and thus can put the striking of the golf ball into full play.

[0020] Furthermore, the present invention is designed in such a way that the included angle between the central axis of the neck section 13 and the vertical line of the center of gravity 12 falls in the range of 40°˜50°, so that the golfer can easily grip the golf club and comply with the ergonomic requirements. It has positive effects on the stability and accuracy of striking the golf ball.

[0021] FIG. 2 shows that the included angle between the striking surface 11 and the vertical line falls in the range of 22°˜28°, so that the golf ball fallen in the rough area beyond the golf course can be stricken towards the hole by using a special angle. In the meantime, it has the iron's “shoveling” effect and the traditional putter's “putting” effect, and thus they provide a more accurate long putting function.

[0022] While the invention has been described by a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
