Abstract

The present invention provides a handle of golf club, which is comprised of a handle core material, foamed sandwiches and an external cover, wherein said core material has a spiral recess coordinating to the holding region, in which said helical foamed sandwich is laid on. As seizing the handle, the construction of the handle can carry out filling the gaps between the fingers and the handle, thereby to buffer the shocking force effort on the hands as striking the ball and increasing the contacting friction force on the hands, and facilitating to control the striking direction steadily and accurately.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a golf club, and more particularly to a handle construction of golf club.

2. Description of Prior Art

In accordance with the conventional handled sport wares, the comfortable effect and the serviceability are considered with great attention in design firstly. Certainly, the design of the handle of golf club is to follow this principle too. But according to the conventional handles of golf club, most of them are made of just only molded rubber so that the cushioning ability and the comfortable effect are not very good as striking.

Additionally, because the handling way of the golf club is to seize up the handle with all the fingers of both hands to retain the handle at the joints of fingers and palms in order to keep in retaining in hand as brandishing the golf club. When the user seizes on the handle with the fingers tightly, there are gaps generated between the finger-gaps and the handle so as to affect the firmness of handling.

Basing on the kinematics and the sport medicine, the bigger the gaps between the fingers and the handle are, the less the contacting area between of them, the small the friction force effort on the hands is, so that means the bigger the shocking force on hands as striking on the ball with the head of the club, the easier the hands are harmed by motion, meanwhile the too big gaps will cause to falter the club as striking, further to affect the flying direction.

On the other hand, for increasing the friction force between the handle and the hands to reduce the slide-off rate, some manufacturers attach a fiber net sheet on the outside of the semi-finished product to be processed so as to burst with the net fibers at the product's surface to increase the contacting friction force with the hands. Although the fiber handle can increase the firmness of the handle, but also the users may feel it not enough steadiness.

OBJECTS AND SUMMARY OF THE INVENTION

It is therefore a main object of the present invention to provide a handle of golf club, in which the cushioning ability on striking and the friction force between the handle and the hands are great increased. For achieving this object, a handle of golf club provided in the present invention should increase the contacting area to fill out the gaps between the fingers and the handle as much as possible so as to make the holding steadily, further to easy control the striking direction smoothly.

An innovated handle, comprised of core material, a foamed sandwich and external cover, achieves this object. Wherein said core material is A formed a spiral concave grasping zone, and said foamed sandwich is lied into the adjacent spiral concave holding zone helically.

Said core material of the handle may be formed into circular recesses, and said foamed sandwiches are laid into said circular recesses relatively and alternately.

Due to adapting above-mentioned construction of handle, said elastic foamed sandwich interlaid the coordinating spiral concave holding zone can absorb most part of reaction force as striking the ball to obtain good cushioning effect. And due to said helical alternative arrangement of two different hardness materials-spiral recess and helical foamed sandwich, as seizing the handle, hands can feel clear boundary sense so that the handle is not easy to slide out from the hands as brandishing.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1, the handle of golf club provided in the present invention has an external surface comprised of an [0019] external cover 4 and core material 2.
Referring to FIG. 2 to FIG. 5, the present invention includes handle [0020] core material 2, helical foamed sandwich 3 and an external cover 4 sequentially from the core to the outside, wherein handle core material 2 has spiral recess 21 coordinating to the holding region (as shown on FIG. 2), in which said helical foamed sandwich 3 is laid on (as shown in FIG. 3 and FIG. 4), said external cover 4 is covered on the outside (as shown on FIG. 5).
As striking the ball by seizing the handle with both hands, the fingers embed into said helical [0021] foamed sandwich 3, and the flanges 211 at the both sides of said spiral recess 21 just fill into the gaps between the fingers and the handle to carry out buffering the shocking force effort on the hands as striking the ball, meanwhile due to the block of said flanges 211 inserting the gaps of the fingers, the friction force contacting with the fingers is increased so that the steady seizing the handle can control the striking direction accurately.
The second embodiment of the present invention is shown in FIG. 6 [0022] 20 and FIG. 7, said core material may be formed into endless groove 21, in which circular foamed sandwiches 3 are laid for carrying out the same functions as above-mentioned.

Claims

I claim:

1. A handle of golf club comprised of a handle core material, foamed sandwiches and an external cover, wherein said core material has a spiral recess coordinating to the holding region, in which said helical foamed sandwich is laid on.

2. A handle of golf club as claimed in claim 1, wherein said core material has several endless groove coordinating to the holding region, in which said circular foamed sandwiches are laid on.
