Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial field of application) The present invention relates to a rubber grip of a golf club, and more specifically, to a grip so that the rubber grip can always be firmly held in the same state. The present invention relates to a rubber grip of a golf club having a structure in which a hard member is embedded.

(Prior Art) It is desired that the grip of a golf club does not loosen during a swing. At the same time, when gripping the grip, it is desired from the viewpoint of stabilizing the ball quality that the positional relationship between the hand and the grip is always the same, that is, that the grip is always in the same state.

Conventional rubber grips cannot meet the above needs because they are made of a constant material.

(Problems to be solved by the invention) The present inventor has found that the conventional rubber grip of the gulf club cannot fully cope with the grip during the swing, and the hand and the grip are always in the same positional relationship. We conducted intensive studies to develop a grip that can be held in the same position and position. Of course, it is necessary to bear in mind that the golf rules other than putters should have a generally circular cross-section in the development.

As a result, the inventor of the present invention has a substantially circular cross section,
In order to obtain a grip that can always be held in a constant state when gripping, does not slip while swinging, and does not loosen, in the longitudinal direction parallel to the axial direction of the grip, a hard core material When it was embedded in a predetermined position, it was found that the above-mentioned needs were fully satisfied, and the present invention was completed.

[Constitution of device]

(Means for Solving Problems) The present invention will be described in brief. The present invention is directed to a rubber for a golf club having a structure in which a large diameter side end of a rubber cylinder having different diameters at both ends is closed by a grip top. In the grip, when at least one or more hard core materials are embedded in the longitudinal direction in parallel with the axis of the grip to at least approximately the middle position in the longitudinal direction from the grip top to the small-diameter end side, the The present invention relates to a rubber grip of a golf club, which has a circular cross section and is configured to detect the hard core material when gripped.

Hereinafter, a configuration and an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a state in which a rubber grip (1) of a golf club having a hard core material according to the present invention is inserted into a shaft. The shape conforms to the rules.

2 to 4 are related diagrams for explaining one embodiment of the present invention.

That is, FIG. 2 is a sectional view taken along the line AA ′ in FIG. 1, and it can be seen that one hard core material (2) is embedded in the rubber of the rubber grip (1). FIG. 3 is a sectional view taken along the line BB ′ in FIG. 1, in which the hard core material (2) is parallel to the axis of the rubber grip (1) and the rubber from the grip top side to the other small diameter end side. It can be seen that the grip (1) is embedded in the rubber in the longitudinal direction up to a substantially middle position in the longitudinal direction. FIG. 4 is a grip state view from the grip top side when gripping the rubber grip (1) of the present invention in which one hard core material (2) is embedded as described above.

As shown in FIG. 4, in the rubber grip (1), the rubber is elastically deformed by the gripping force of the hand, so that the hard core material (2) embedded in the rubber causes the valley of the second joint part of the finger. To project into. Therefore, the rubber grip (1) has increased resistance with the surface of the palm and can be firmly gripped.
Also, club swingers can make the rubber grip (1) always in the same state by contacting the protruding part formed when holding the golf grip (1) with the valley of the joint part of the finger formed when holding the hand. ) Can be held. The club swinger stabilizes various spherical balls (for example, slice balls or hook balls) by consciously changing the contact position of the protruding portion with the palm, using the protruding portion as a guide. Can be created. That is,
Learn what kind of ball is hit when the protruding part and the contact part of the palm when gripping the rubber grip (1) are in the positional relationship with the protruding part as a guide Then, it is possible to stably produce a hit ball with a desired quality.

FIG. 5 shows the second embodiment of the present invention.
It is a corresponding figure of a line cross section. In FIG. 5, a hard core material (2)
6 are embedded in the rubber of the rubber grip (1). In this case, the plurality of projecting portions formed when gripped will come into contact with the valleys of the joint portions of the plurality of fingers or the wrinkle portion of the palm, and like the first embodiment described above, The purpose can be achieved.

Next, a method for molding the rubber grip containing the hard core material of the present invention will be described.

First, a desired number of hard core materials having a predetermined length such as a metal wire, a synthetic resin rod, and a string made of polyamide fiber or cotton are prepared. The hard core material may be sandwiched between plate rubbers prepared by mixing raw rubber with additives and vulcanizing agents so as to be parallel to the axis of the grip, and then put into a grip mold for vulcanization molding.

Although the configuration and the embodiment of the rubber grip of the present invention have been described above with reference to the drawings, it goes without saying that the invention is not limited to the drawings unless the gist of the present invention is exceeded. For example, the number of hard cores to be embedded or the length of the hard cores not only affects the grip portion but also the entire length can be freely changed.

[Effect of device]

The rubber grip of the golf club of the present invention has the following excellent effects: (i) It has a circular cross-sectional shape when inserted into the golf shaft, and grips when the player grips the rubber grip. Due to the difference in hardness between the rubber and the hard core material, the hard core material embedded in the rubber protrudes. Therefore, the resistance between the projecting portion and the surface of the palm is increased, and a firm grip can be achieved.

(ii) Also, if each player remembers which part of the palm to contact the protruding part with when holding the rubber grip, for example, a predetermined finger joint that can be made when the protruding part is held. If you touch it in the valley of the part,
You can always hold the golf club in the same state.

(iii) Furthermore, by using the above-mentioned protruding portion as a guide, the player grasps the ball at various ball qualities (depending on whether the club face is open or covered, whether it is a scale or hook grip) It is possible to play by confirming the positional relationship between the protruding portion and the palm when the ball is made into a ball quality. Therefore, the rubber grip of the present invention is useful for stably producing a desired hit ball quality.
