Description

  The present invention relates to a golf club having a transparent grip, and more particularly, a sheet layer on which graphics and characters are printed is formed on the surface of a shaft to which the grip is coupled, and a coating film layer is formed on the surface of the sheet layer. The present invention relates to a golf club having a transparent grip on which a grip made of a transparent body is fitted so as to not only protect the sheet layer but also make it possible to more clearly confirm the content printed on the sheet layer.

  Since the grip of the golf club must be formed so that it can be easily grasped and not slipped by hand, most of it is laminated with a constant thickness spirally around the shaft using rubber or synthetic resin material in the form of a long and narrow band or band. It is formed.

  A grip formed by such a coating material lamination method requires a large amount of labor, and even if the coating material is prepared to an appropriate length in advance and wound, factors such as a winding force, a winding position, and a gap are required. The phenomenon that the coating material prepared by the method remained or was insufficient occurred frequently. Therefore, recently, molded articles manufactured not only to enhance gripping force by integrally forming unevenness on the surface of the grip but also to have excellent elasticity without slipping have been applied.

  Since the grip of such a golf club is a portion that is easily stained by sweat or the like during exercise, it is formed by being wound with a covering material as described above, but all formed by molding are opaque. It is generally manufactured in dark colors such as black or indigo.

  However, among golf clubs, the grip is the part where the gaze of the person is most often poured, so each manufacturer molds public letters and figures such as company logos and product names into engravings or intaglios. Informs the source.

  As described above, a large amount of money is required to produce a golf club grip having a trade name three-dimensionally engraved thereon by engraving or engraving. The above method could not be applied personally only if possible. So, sometimes when trying to give or donate a golf club as a gift or donation to commemorate a competition or special event at the public or government, stickers with commemorative pictures or letters printed on the outer surface of their grips And expressed the meaning of various competitions and events.

  However, in this case, the exerciser causes a lot of sweat on the hand to adhere to the grip, so that the sticker has not adhered for a long time and is now peeled off, and the adhesive on the back surface of the sticker has become sticky to the hand, making it inconsistent. There was a drawback that gave pleasure.

  On the other hand, the existing grip is a grip made of an achromatic rubber material such as black, indigo or gray, and the golfer cannot easily grasp the golf club and slips or twists when hitting a golf ball. Thus, by providing grooves, protrusions, lines, or the like on the outer surface of the grip or by mixing threads, the surface of the grip was made rough so that the golf club could not come out of the golfer's hand during the swing.

  However, the existing grip made in this way is easily worn due to the properties of the material, and the worn grip becomes slippery, causing a hindrance to the golf score and having to change the grip frequently, resulting in economical loss. Was enormous.

  As the inventor has been involved in this industry for many years, if various printed materials are built inside the golf club grip so that they can be viewed from the outside, not only can the publicity effect of the production and sales company be obtained, but also the personal effect can be obtained.

  Hereinafter, a structure and a preferred embodiment of a golf club having a transparent grip according to the present invention will be described in detail with reference to the accompanying drawings.

  1 is a perspective view showing one embodiment of a golf club having a transparent grip, and FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 showing a first embodiment of the golf club having a transparent grip according to the present invention. FIG. 3 is a cross-sectional view of the golf club having a transparent grip according to the second embodiment of the present invention, taken along line AA of FIG. 1, and FIG. 4 is a flowchart illustrating a manufacturing process of the golf club having a transparent grip according to the present invention. FIG. 5A is a sectional view taken along line AA of FIG. 1 showing a third embodiment of a golf club having a transparent grip according to the present invention, and FIG. 5B is a sectional view of FIG. It is a principal part enlarged explanatory view.

  As shown in FIGS. 1 to 5, the grip G of the golf club having a transparent grip according to the present invention includes a transparent body layer 40 having an appropriately sized cavity 400 into which the end of the shaft 10 is inserted, and the shaft 10. It is firmly connected so that separation is impossible artificially.

  That is, the structure of the first embodiment of the present invention using a golf club having a transparent grip will be described with reference to FIG. 2. The shaft G is located inside the grip G, and a sheet layer is formed on the outer peripheral surface of the shaft 10. 20 are formed. The sheet layer 20 is attached to the shaft 10 by an adhesive layer 11, and the adhesive layer 11 is formed of a sheet-like adhesive such as a double-sided tape or is coated with a liquid adhesive. Formed.

  The shaft 10 on which the sheet layer 20 is formed is inserted into the cavity 400 of the transparent body layer 40 and joined by the adhesive layer 31. The adhesive bonding the shaft 10 and the transparent layer 40 may be formed by applying a sheet-like adhesive such as a double-sided tape or a liquid adhesive to form the adhesive layer 31. Can be formed by selectively applying an adhesive to the surface of the sheet layer 20 or the inner peripheral surface of the transparent body layer 40.

  Immediately after the formation of the adhesive layer 31, the shaft 10 is inserted into the transparent body layer 40, and the shaft 10 is formed by the adhesive layer 31 formed on the surface of the sheet layer 20 or the inner peripheral surface of the transparent body layer 40. Instead of reaching the bottom of the cavity 400, it is glued in the middle and hardens. Therefore, before the shaft 10 is inserted into the cavity 400 of the transparent layer 40, a highly volatile solvent 50 such as a thinner is sprayed or sprayed on the adhesive layer 31 or the inner peripheral surface of the transparent layer 40. The viscosity of the adhesive layer 31 is temporarily reduced by application so that the adhesive layer 31 can be smoothly inserted. Here, when an oil containing a rust-preventive component, that is, an rust-preventive oil is used in place of the solvent having a high volatility, the viscosity of the adhesive layer 31 is also reduced while preventing the shaft from being rusted (generated). The shaft is temporarily lowered and the shaft is well fitted to the grip.

  The shaft 10 which is smoothly inserted without friction into the cavity 400 of the transparent body layer 40 by the sprayed or applied solvent 50, the solvent 50 evaporates and the adhesive layer 31 solidifies when left for a predetermined time, and the shaft Reference numeral 10 is fixed to the transparent body layer 40 together with the sheet layer 20, and is firmly connected so that the position is not changed or damaged by a shock due to motion, and is maintained in the same position.

  On the sheet layer 20, a publicity content such as a photograph or a picture indicating a special event or a tourist attraction, a trade name or a trademark of a production and / or sales office, or an address or a name indicating possession of a specific person is directly printed. The printed matter on which the content of the publicity is recorded is attached.

  The sheet layer 20 may be made of paper, as conventionally used. However, the sheet layer 20 has a gripping feeling when the grip G is gripped and a shot feeling transmitted to the hand when the ball hits the head H of the golf club. According to the present invention, the sheet layer 20 is made of an elastic polymer material such as vulcanized rubber, elastic fiber, or damping foil to increase the impact. material). By using the elastic polymer material for the sheet layer 20, the transmission of the impact from the shaft 10 of the golf club to the grip G after the swing is suppressed, the impact and damage applied to the hand are reduced, and as a result, the swing feeling is improved. You can expect an effect to make it.

  The second embodiment of the present invention is an improvement of the first embodiment. Referring to FIG. 3, the photograph, the picture, the graphic, the character, etc. are printed or the printed matter on which the contents of the publicity are recorded is attached. A thin and transparent coating layer 30 is formed on the surface of the sheet layer 20 to protect the printed contents and the sheet layer 20. With such a configuration, as in the first embodiment, the shaft 10 is fitted into the transparent body layer 40 with the sheet layer 20 formed on the shaft 10 and the adhesive 31 applied to the surface of the sheet layer 20. At this time, since the viscosity of the adhesive 31 is temporarily reduced so that the shaft 10 is smoothly inserted into the cavity 400 of the transparent body layer 40, a highly volatile solvent such as a thinner is applied on the adhesive 31. The solvent is soaked in the sheet layer 20 and the printed content is blurred or spotted, so that the public information content is not clearly displayed and the appearance becomes unsightly, or the adhesive 31 is fluffed or clumped by the solvent. This is for preventing problems that can occur, such as forming a scar, or forming an uneven portion in a state where the final grip is installed with the residue of the adhesive 31 accumulated.

  That is, by coating a plastic film on the printed surface of the sheet layer 20 to form the coating film layer 30, the shaft 10 is sprayed onto the adhesive layer 31 before being inserted into the cavity 400 of the transparent body layer 40. Alternatively, the solvent 50 applied not only prevents the printed contents from being blurred or uneven, but also prevents the sheet layer 20 from being pushed or broken by friction with the inner peripheral surface of the cavity 400. Since the surface of the coating film layer 30 is flat and uniform, it is easy to insert the coating film layer 30 into the cavity 400 for coupling with the transparent body layer 40.

  As described above, the coating film layer 30 that protects the content printed on the sheet layer 20 and provides a beautiful gloss is colored in a colorless or pale hue, but all the light passes therethrough and the content printed in the inside thereof is printed. Is formed so as to be completely visible, and a material such as polypropylene (PP), polyvinyl chloride (PVC), or a laminating film is applied.

  The coating film layer 30 is formed by coating a thin vinyl film on the surface of the sheet layer 20 on which the printed matter on which the publicity content is recorded is directly printed or heated and pressed by a heating rolling tool or an adhesive. Various usual coating methods such as adhesion can be used. The coating layer 30 can form the coating layer 30 on the sheet layer 20 attached to the shaft 10. The coating layer 30 is formed by coating the surface of the sheet layer 20 in advance. If 20 is adhered to the shaft 10, the process is further simplified.

  On the other hand, as a third embodiment of the present invention, referring to FIGS. 5A and 5B, the golf club having a transparent grip according to the present invention has the above-mentioned coating film if necessary in order to further enhance the feeling of grip and hitting. Many fine projections can be formed on the surface of the layer 30. FIG. 5B is an enlarged explanatory view of a main part X of FIG. 5A. By pressing the surface of the coating film layer 30 to form a large number of fine protrusions, the swing feeling can be further enhanced together with the sheet layer 20 made of the elastic polymer material. In addition, the coating film layer 30 having a large number of fine protrusions on the surface has a smaller friction surface than the flat surface, so that it can be more easily inserted into the cavity 400 for coupling with the transparent body layer 40. .

  When the shaft 10 is coated with the sheet layer including the coating film layer 30 as described above, the shaft 10 is combined with the transparent body layer 40. At this time, the transparent body layer 40 used is formed of a cylindrical body having a shaft insertion cavity 400 formed by an integral molding method such as injection molding by applying silicon, urethane, a PVC composite material, rubber, and other transparent materials. The material constituting the transparent body layer 40 is made of a polyurethane resin, ethylene, propylene, or a non-conjugated diene having a suitable elasticity and a high frictional resistance so that the feel is not particularly slippery when gripping, and capable of mass injection molding. A synthetic rubber (EPDM), a transparent material made of a synthetic rubber further containing styrene butadiene rubber, dioctyl phthalate, natural rubber or ethylene-vinyl acetate copolymer (EVA) is applied to the synthetic rubber (EPDM). Is desirable.

  The transparent body (I, II, III, IV) made of the above-mentioned four materials, which is desirable to be applied to a golf club having a transparent grip according to the present invention, is manufactured by the American Society for Testing and Materials (ASTM; American). The results of measuring the physical properties by the standard method of Society of Testing Materials) are as follows (I: polyurethane resin, II: synthetic rubber (EPDM), III: synthetic rubber (EPDM) and styrene butadiene rubber, phthalate Dioctyl acid, a mixture of natural rubber, IV: ethylene-vinyl acetate copolymer (EVA)).

  Further, the friction coefficient, hardness, and tensile strength of the transparent body (I, II, III, IV) grips made of the above four kinds of materials according to the present invention are measured, and the average value thereof is used. Table 2 shows a comparison of the friction coefficient, hardness, and tensile strength value of the rubber grip.

  As can be seen from the two measurement results of Tables 1 and 2, the transparent layer 40 made of the material according to the present invention has excellent hardness, is not easily worn or broken, and has a low production cost. Not only is the product economical, it feels good, has good grip and restoring power, and is non-slip and soft. In addition, since the hand does not sweat or the moisture does not penetrate the grip in rainy weather, the grip does not fuzz or twist, and the original shape is maintained, so the golfer can swing without wearing gloves, so the golfer can accurately A good shot feeling can be felt, and the transmission of force at impact is good.

  In addition, the transparent layer 40 is formed to be transparent so that all the light beams can pass through and the sheet layer 20 inserted therein can be completely seen, but it can be colored to be colorless or pale. In order to make the contents printed on the sheet layer 20 more transparent, it is preferable to make the material forming the transparent body layer 40 transparent and soft.

  On the other hand, if the transparent body layer 40 is further added with a fragrance such as a rose scent, a lightly scented or antibacterial nano material, a fragrant scent drifts when the grip G is gripped, and bacteria inhabit the dirt caused by sweat and dust. The easy grip G can be kept clean.

  The golf club having a transparent grip according to the present invention formed by the structure as described above can be summarized with reference to FIG. 3. First, an adhesive 11 is applied around the end of the shaft 10 for publicity. A sheet layer 20 to which a printed matter on which photographs, pictures, figures, and characters are printed or on which a publicity content is recorded is attached, and a coating film layer 30, 30 'is formed thereon, or a pre-printed sheet A transparent and thin vinyl coating is applied to the surface of the shaft 10 to prepare the sheet layer 20 on which the coating film layers 30 and 30 ′ are already formed, adhere to the end of the shaft 10, and further spray an adhesive thereon. An adhesive layer is formed by laminating an adhesive on the sheet, and a solvent 50 having a high volatility is sprayed or applied to the adhesive layer 31 or the inner peripheral surface of the cavity 400 of the transparent body layer 40, and then the empty layer is formed. Drying predetermined Insert within 400 hours, the transparent layer 40 is completed is firmly secured around the shaft 1 together with the seat layer 20 and the coating layer 30, 30 '.

  Therefore, according to the golf club having a transparent grip of the present invention, since the solvent 50 is not absorbed into the sheet layer 20 by the coating film layers 30 and 30 ', there is no spot or bleeding, so that the printed portion is clear. The intended aesthetic feeling was fully expressed and appeared, and in particular, the sheet layer 20 made of an elastic polymer material further enhanced the impact relaxing effect as well as the gripping feeling and hitting feeling. Further, the transparent body layer 40 was smoothly inserted into the coating film layers 30 and 30 'due to the adhesiveness of the surface thereof, so that the coating layers 30 and 30' could be more firmly bonded.
