Description

Manufacturing method of transparent grip < RTI ID = 0.0 >

In the present invention, grips and grips are formed on the handle of a shaft (e.g., a sports tool or a working tool and a medical tool), and grips provided to protect the hands are formed in a transparent picture. Shape, and character to be exposed to the outside, and a method of manufacturing the transparent grip.

In the shaft handle portion of various sports articles, a grip having an elastic force is provided to protect the grip and the gripping force and the hand, and a typical example thereof is a golf club. The background art described below will be described using a golf club as a model.

Generally, grips of golf clubs should be formed so as not to be slippery and easy to grip by hand, so they are formed by laminating around the shaft grip portions with a certain thickness by using a covering material of rubber or synthetic resin material, which is mostly in the form of an elongated strip or band.

In recent years, a transparent resin molding which is not only slid but has excellent elasticity has been applied as well as increasing the gripping force by forming irregularities on the surface of the grip.

The above-mentioned transparent grip is the most visible part of the golf ball among the golf clubs. In each manufacturer, a promotional character such as a company logo or a product name shapes a figure in a embossed or engraved shape and informs the origin of the figure.

As described above, it takes a great deal of money to manufacture golf grips integrally embossed or embossed on the embossing or engraving, so that it is possible only when the manufacturer produces a large amount of time for the company promotion, but the above method can not be applied personally .

So, when the public or government wants to donate or donate a golf club to commemorate a tournament or a special occasion, a sticker with a picture or letter printed on the exterior surface of the grip will be attached, .

However, in this case, the sweat of the hand is buried in the grip much, and the sticker is not stuck for a long time, and the sticky back adhesive sticks to the hand and the stick becomes sticky.

In addition, the grip is easily worn due to the characteristics of the material, and the worn grip has a large slipperiness, which causes a disadvantage to the golf score and necessitates frequent replacement of the grip, which is economically disadvantageous.

In order to solve the above problem, as shown in Fig. 1, a sheet made of paper, which is attached to the outer surface of the grip mounting portion 11 of the shaft 10 and is used to display a promotional pattern 21a printed in a plane, A transparent material layer 22 surrounding the sheet layer 21 and a cap 23 made of a transparent material integrally attached to the end of the transparent material layer 22 and having a through hole 23a, A transparent golfer grip 20 is presented.

1, a head 30 for hitting a golf ball is mounted on the lower portion of the shaft 10, and the cap 23 is made of a transparent soft urethane.

The transparent golfer grip 20 thus constructed is provided with a sheet layer 21 on which a promotional pattern 21a such as a photograph, a figure, a figure, a character or a pattern is printed in the grip and the promotional pattern 21a of the sheet layer 21 Can be easily seen from the outside, and the damage of the sheet layer 21 can be prevented, and the promotional pattern 21a printed on the sheet layer 21 can be more clearly seen from the outside, There is an advantage to be able to make accurate hit.

However, in the conventional transparent golf grip 20 constructed as described above, since the cap 23 is made of a transparent material and the inside is visible through the transparent cap 23, there is a problem that the cosmetic appearance is not structurally beautiful.

Further, the conventional transparent golf grip 20 has a problem in that the cap 23 is structurally made of a transparent soft urethane so that the strength is weak, so that the cap 23 is easily structurally worn and its service life is shortened.

The conventional transparent golfer grip 20 is structurally poor in gripping feeling because the sheet layer 21 is made of paper and the promotional pattern 21a is smoothly printed on the surface of the sheet layer 21 .
