Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a golf club, and more particularly, to a golf club having a convex rib for reinforcement.

[0002]

[Prior art]

 Conventionally, the club body of most golf clubs, no matter what material is manufactured, has a uniform taper shape, a handle is set at the large diameter end, and a head that hits the ball at the small diameter end is connected. You. Therefore, the position that receives the force when swinging the club or hitting the ball is the middle step of the club and the head approaching the small diameter, and the phenomenon of bending always occurs. Also, since the golf club is a thin rod, the club body is easy to talk. In other words, as a force arm between the head hitting the ball and the center axis of the club, the product of the multiplication of the acting force and the force arm becomes a talk received by the club body, causing the phenomenon of twisting the golf club. . Ultimately, golf clubs lack mechanical strength due to bending and twisting phenomena. For this reason, the industry is developing various reinforcement measures. Among them, the reinforcing means for golf clubs made of fiber composite material is devised by the fiber arrangement inside the majority. Golf clubs made of any material for external reinforcement can be divided into the following two forms.

One of them is to provide a convex portion 12 in a small area of a club body of a golf club 10 as shown in FIG. The other is to provide a long convex portion 16 in a large area of the club body of the golf club 15 as shown in FIG. Although the above-mentioned projections 12 and 16 have different lengths, the structural means are exactly the same. In other words, the cross sections of the convex portions 12 and 16 become conical, the diameter at the center is maximum, and the conical shape gradually decreases as moving from the center to both ends.

[0004]

[Problem to be Solved by the Invention] The golf club having the above structure not only provides the reinforcing effect by the arrangement of the convex portions, but also avoids bending, twisting, etc. from a simple tapered club. Is also improved. However, increasing the mechanical strength is still inadequate and needs to be improved for the following reasons.

[0005] The protrusion is a straight pipe with a larger diameter and is still pipe-shaped. From the point of view of mechanical mechanics, the strength is relatively increased simply by increasing the diameter, but the effect of avoiding bending, twisting, etc., is insufficient. In other words, the mechanical strength of the golf club cannot be significantly improved. Since the convex portion is solid, the material cost increases.

[0006] Due to the large amount of material, the club is heavy and wastes power for the user. SUMMARY OF THE INVENTION In order to improve the above drawbacks, a main object of the present invention is to provide a golf club having improved mechanical strength of the golf club. It is another object of the present invention to provide a golf club having a low weight.

[0007]

[Means for Solving the Problems]

 According to the golf club of the present invention for achieving the above-mentioned object, a golf club is provided with a tapered club body having a large diameter end and a small diameter end for installing a handle and a head for hitting a ball. The club has at least one reinforcing means. The reinforcing means is provided with at least two convex ribs, and protrudes from the club body in a vertical direction and along the axial direction of the club. Moreover, the convex ribs are arranged at equal angular intervals around the circumference of the club body. The reinforcing means greatly improves the strength of the golf club. Furthermore, it not only has excellent mechanical strength, but also has the effect of saving material.

[0008]

[Embodiment of the invention]

 Hereinafter, several embodiments of the present invention will be described with reference to the drawings.

First Embodiment As shown in FIG. 3, a golf club 20 according to a first embodiment has a tapered club body 22, a handle 26 is provided at a large-diameter end 24, and a ball is provided at a small-diameter end 25. The head 28 is connected. The club body 22 has at least one reinforcing means. As shown in FIG. 3, the substantial reinforcing means is formed of two elongated convex ribs 30 having the same length, and is provided in a small area at the same height in the middle of the club body 22. More specifically, it protrudes vertically along the axial direction of the club body 22. Moreover, they are arranged at the same angular interval of 180 ° on the circumference of the club. As shown in FIG. 4, the thickness of the central portion of the corresponding convex rib 30 is maximum, gradually decreases from the center to both ends, and has a single thickness near both ends.

FIG. 5 is a sectional view of a second embodiment of the present invention. Although the structure is almost the same as that of the first embodiment, the difference from the first embodiment is that the number of the convex ribs 44 in the club body 42 of the club 40 is three. As in the first embodiment, the clubs are arranged at equal angular intervals on the circumference of the club, and have a structure in which the center is thick and both ends are thin.

FIG. 6 is a cross-sectional view of a third embodiment of the present invention. The difference from the first embodiment is that the number of convex ribs 54 in the club body 52 of the club 50 is six. As in the first embodiment, the clubs are arranged at the same angular interval on the circumference of the club, and have a structure in which the center is thick and both ends are thin.

(Fourth Embodiment) In the first embodiment shown in FIG. 3, a reinforcing convex rib is provided in the middle of the club body. However, as in the fourth embodiment shown in FIG. It may be provided at the small-diameter end 65. Fifth Embodiment As shown in FIG. 8, reinforcing convex ribs 74 may be provided at the middle and small diameter ends of the club body 72 of the club 70.

FIG. 9 is a cross-sectional view of a sixth embodiment of the present invention. The difference from the first embodiment is that the convex rib of the first embodiment is provided at a local portion of the club, and the convex rib 84 of the sixth embodiment is provided on the whole body of the club 82 along the axis of the club 80. Is to be done. Here, the remaining length other than the handle and head is called the whole body. 9 has a tapered shape in which the outer diameter of the convex rib 84 of the club 80 gradually decreases from the large diameter end 86 to the small diameter end 86. Since three convex ribs 84 are provided on the club body 82, the cross-sectional shape is the same as the shape shown in FIG.

(Seventh Embodiment) A seventh embodiment shown in FIG. 10 is substantially the same as the sixth embodiment shown in FIG. 9, and the convex ribs 94 of the club 90 are also provided on the whole body of the club body 92. The difference from the sixth embodiment is that the thickness at the center of the convex rib 94 is maximum, and the thickness at both ends of the convex rib 94 is gradually reduced. In the sixth embodiment shown in FIG. 9, the thickness of the convex rib 84 is uniform.

According to the present invention, the present invention can be applied not only to a simple tapered club but also to a club having another structure. Eighth Embodiment A club 100 according to an eighth embodiment shown in FIG. 11 is generally tapered, but the club body 102 is divided into an upper section 103 and a lower section 104. The upper stage 103 is formed in a head-to-tail connection by some cylinders varying in diameter from small to large dimensions. In other words, the closer to the head, the smaller the diameter, so that it becomes a roughly tapered stairway rod. In the lower stage 104, convex ribs 106 are provided along the axial direction of the club.

Ninth Embodiment A ninth embodiment shown in FIG. 12 has a structure in which a convex rib 115 is provided along the axial direction of the club on the upper part of the club body 112 of the club 110. The difference from the eighth embodiment shown in FIG. 11 is that the lower stage 114 is connected to the lower stage 114 by a column 116 having a gradually decreasing diameter to form a tapered step rod.

Tenth Embodiment In a tenth embodiment shown in FIG. 13, the club body 122 of the club 120 is divided into an upper section 123, a middle section 124, and a lower section 125. The upper row 123 and the lower row 125 are stair rods, and the middle row 124 is provided with a convex rib 126 and is connected between the upper row 123 and the lower row 125.

Eleventh Embodiment An eleventh embodiment shown in FIG. 14 is a stair rod in which the outer diameter of the whole body of the club body 132 of the club 130 gradually decreases from top to bottom. On the annular circumference of each step rod 133, convex ribs are arranged vertically at the same angular interval along the axial direction of the club. The thickness of the central portion of the corresponding convex rib 134 is the largest, gradually decreases from the center to both ends, and has a single thickness near both ends.

In addition to the embodiments described above, a simple tapered club may be provided with a plurality of reinforcing means according to the present invention. Such reinforcements are formed at the head-to-tail junction along the axis of the club. Moreover, the diameter of the convex rib of the reinforcing means gradually decreases from the large-diameter end to the small-diameter end. After all, the structure of the club is almost the same as that of FIG. 14, and it is simply a stair rod formed by a convex rib whose outer diameter gradually decreases.

In short, the golf club having the convex ribs for reinforcement of the present invention has the following effects more than the conventional golf club. (1) From the point of view of mechanical mechanics, since the convex ribs are elongated, they can receive a large force in the vertical direction. This provides the club with excellent mechanical strength and avoids bending, twisting, etc. The convex rib geometry significantly increases the club's strength. Furthermore, providing two or more convex ribs symmetrically in the club has a synergistic effect for improving strength. Therefore, compared to the conventional method of only increasing the diameter of the club, it is worthwhile for a remarkable effect.

(2) Compared with the conventional method of increasing only the diameter of the club, the present invention has the same diameter as shown in FIG. 6, for example, but the conventional diameter range is a virtual line. The diameter range of the present invention is indicated by a sectional line. The present invention significantly reduces the volume and material, and greatly reduces the material cost, because there is a groove gap between adjacent convex ribs.

(3) Since the volume and the material are significantly reduced, the weight of the club is also relatively reduced. Summarizing the above, according to the present invention, the golf club having convex ribs for reinforcement is certainly a novel design.
