Description

Golf club with transparent grip {golf club with transparent grip}

The present invention relates to a golf club that is transparent grip, more specifically, a sheet layer printed with figures and letters is formed on the surface of the shaft to which the grip is coupled, and a coating film layer is formed on the surface of the sheet layer, and the grip is made of a transparent body thereon. The grip is not only for protecting the sheet layer, but also for a golf club that has a transparent grip that can clearly check the printed contents on the sheet layer in appearance.

Since the grip of the golf club is easy to be gripped by hand and is not slippery, most of the golf club is formed by spirally laminating a certain thickness around the shaft by using a thin long band or band-like rubber or synthetic resin covering material.

The grip formed by the cladding method of this cladding requires a lot of labor and the phenomenon that the cladding prepared by the factors such as winding force, winding position and spacing remains or falls short even if the covering material is prepared and wound in advance in an appropriate length. This has happened frequently. Therefore, in recent years, many moldings have been applied that are formed to have unevenness on the surface of the grip integrally to increase gripping force and to be non-slip and have excellent elasticity.

Since the golf club grip is a part that is easily contaminated by sweat or the like during exercise, it is generally wound and formed by the coating material as described above, or formed by molding, all of which are opaque and manufactured in dark colors such as black or indigo blue.

However, among the golf clubs, the grip part is the part where the eyes of the person touch the most, and each manufacturer is informing the source by embossing or engraving promotional letters or figures such as a company logo or a brand name.

As such, it takes a lot of money to produce a golf club grip that is engraved on it by embossing or engraving. Therefore, it is possible only when the producer produces a large amount at one time to promote the company, and personally, the above method cannot be applied. .

In order to compensate for this, recently, various prints are embedded inside the golf club grip to be viewed from the outside. Golf clubs with transparent golf club grips have been developed to prevent the loss and to remember the meaning of the event for a long time.

The conventional transparent golf club grip G ', as shown in Fig. 5, by applying the adhesive 2 around the end of the shaft (1) to attach a sheet of paper 3, printed pictures, drawings, figures, characters, etc. And laminating the adhesive 4 thereon, and inserting the transparent body 5 with the cavity 6 thereinto dry the transparent body 5 around the shaft 1 together with the sheet paper 3. It is configured to be securely attached.

This configuration is such that when the sheet 3 is attached to the shaft 1 and the shaft 1 is inserted into the transparent body 5 with the adhesive 4 applied to the surface of the sheet 3, the transparent body 5 The viscosity of the adhesive 4 should be temporarily lowered so that the shaft 1 can be smoothly inserted into the cavity 6 of. For this purpose, a highly volatile solvent such as thinner is sprayed or applied onto the adhesive 4.

However, when the solvent is sprayed or applied to the conventional sheet 3, the adhesive 4 may be swollen or agglomerated by the solvent, which may cause traces, and the residue of the adhesive 4 may be caught, resulting in a final grip. There was a problem that the uneven portion occurs in the installed state or the grip is not smooth when the grip is not picked outside.

In addition, the sprayed or applied solvent penetrates the sheet paper 3 so that the printed ink is smeared or stained so that the contents to be expressed are not clearly displayed and the appearance is not good, thereby degrading the quality of the product.

The present invention has been made to solve such a conventional problem, to provide a golf club that is transparent grip to improve the quality of the sheet layer embedded inside the transparent grip to improve the quality.

In other words, the golf club grip of the present invention is transparent by forming a thin coating layer on the printed sheet, so that the sheet is not stained and the printed content on the surface of the grip does not bleed and deform or warp so that the grip can be maintained semi-permanently. It aims to provide a golf club.

Another purpose of the golf club that is transparent to the grip of the present invention is to use an elastomeric material as a sheet inserted into the grip, or to form a fine protrusion on the surface of a thin transparent coating layer so as to increase grip and hitting feeling and to reduce shock. To provide a golf club.

These objects as described above are achieved by providing a transparent golf club grip of the subject innovation, according to the transparent golf club grip of the subject innovation is formed on the surface of the shaft to which the grip is bonded, the sheet layer is printed, In the golf club that the grip is inserted into the portion of the golf club is bonded to the adhesive, characterized in that the coating layer is formed on the surface of the sheet layer to protect the sheet layer.

In addition, the grip of the present invention is a transparent golf club is characterized in that the material of the sheet layer is an elastomeric material to increase the grip and hitting feeling and to reduce the impact.

In addition, the present invention is characterized in that the fine projection is formed on the surface of the coating film layer.

The transparent layer forming the grip of the present invention is colored in a colorless or light color, but is transparently formed so that the sheet layer inserted therein can be completely seen through all the light rays, and a polyaddition reaction between diisocyanate and glycol And biscarbamic acid esters and glycols, transesterification of diamines with ethylene carbonates, or bisurethanes with diamines, and two types of polyurethane resins of ordinary polyether type and polyester type Can be applied. Substantially, the transparent layer is composed of a cylindrical body having a cavity for shaft insertion by an integral molding method such as injection molding.

The shaft, the sheet layer, the coating film layer and the transparent layer are fixed to each other in whole or in part by a double-sided tape or a liquid colorless transparent adhesive formed on a conventional sheet.

Hereinafter, with reference to the accompanying drawings will be described in detail the structure of the golf club grip is transparent according to the present invention.

1 is a perspective view showing an embodiment of a golf club grip is transparent, Figure 2 is a cross-sectional view taken along line AA of Figure 1 showing a first embodiment of a golf club grip is transparent according to the present invention, Figure 3 is a grip according to the present invention The manufacturing process of the transparent golf club is shown step by step. Figure 4 is a cross-sectional view taken along the line A-A of Figure 1 showing a second embodiment of a golf club grip is transparent according to the present invention.

As shown in Figures 1 and 2, the grip G of the golf club transparent grip according to the present invention is a transparent layer having a cavity 400 of a suitable size that can be inserted into the end of the shaft 10 as usual 40 and shaft 10 are firmly coupled so that they cannot be artificially separated.

That is, referring to FIG. 2, the grip G has a shaft 10 positioned therein and a sheet layer 20 formed on an outer circumferential surface of the shaft 10. The sheet layer 20 is attached to the shaft 10 by an adhesive layer 11, wherein the adhesive layer 11 is formed by a sheet-like adhesive such as a double-sided tape or a liquid adhesive is applied. Can be formed.

The sheet layer 20 is printed with a photograph or picture representing a special event or a tourist attraction, a trade name or a name of a producer and / or a distributor, or an address or a name that may indicate the possession of a specific person.

The sheet layer 20 may use paper as is conventionally used, but the grip feeling when grabbing the grip (G) and the hitting feeling delivered to the hand when the ball hits the head (H) of the golf club, and alleviates the impact In the present invention, an elastomeric material such as vulcanized rubber, elastic fiber, or damping foil is used as a material constituting the sheet layer 20. By using the elastomeric material in the sheet layer 20, the impact transmission from the shaft 10 of the golf club to the grip G after the swing is suppressed, thereby reducing the impact and damage to the hand and consequently improving the swing feeling. You can expect.

On the surface of the sheet layer 20 on which the photographs, drawings, figures, characters, and the like are printed, a thin and transparent coating layer 30 is formed to protect the printed content and the sheet layer 20. That is, when the shaft 10 is inserted into the cavity 400 of the transparent layer 40 by forming a coating layer 30 by coating a plastic film on the printed surface of the sheet layer 20, the adhesive layer 31 is formed. Not only prevents the printed content from smearing or staining by the sprayed or applied solvent 50, but also prevents the sheet layer 20 from being pushed or torn by friction with the inner circumferential surface of the cavity 400. . In addition, since the surface of the coating layer 30 is flat and even, it is easy to insert into the cavity 400 for bonding with the transparent layer 40.

As described above, the coating layer 30 which protects the printed content on the sheet layer 20 and gives a beautiful luster may be colored in a colorless or pale color, but may completely transmit the light and completely display the printed content therein. It is formed so as to be transparent, and materials such as polypropylene (PP), polyvinyl chloride (PVC), laminating film, and the like may be applied.

The coating layer 30 may be formed by coating a thin vinyl film on the surface of the printed sheet layer 20 and heating or pressing it with a hot rolling tool, or attaching it with an adhesive. The coating film layer 30 may form a coating film layer 30 on the sheet layer 20 attached to the shaft 10, but the coating layer is formed on the surface of the sheet layer 20 in advance to form a coating film ( Attaching 20 to the shaft 10 may make the process simpler.

On the other hand, the grip of the present invention is transparent golf clubs may be coated so as to form a fine projection on the surface of the coating film layer 30 'as necessary to further increase the grip and hitting feeling (see Fig. 4). By forming fine protrusions on the surface of the coating film layer 30 ', a swinging feeling can be further increased together with the sheet layer 20 made of the elastomeric material. In addition, since the coating layer 30 ′ having fine protrusions formed on the surface thereof has a smaller friction surface than the flat surface, the coating layer 30 ′ is more easily inserted into the cavity 400 for bonding with the transparent layer 40.

As described above, when the sheet layer 20 including the coating layer 30 is coated on the shaft 10, the shaft 10 is coupled to the transparent layer 40. At this time, the transparent layer 40 is applied to the polyurethane resin having a suitable elasticity and high frictional resistance is applied so as not to feel good and slippery when gripping, and is composed of a cylindrical body with a shaft insertion cavity 400 by an integral molding method such as injection molding do. In addition, the transparent layer 40 is formed to be transparent so that all the light beams are transmitted and the sheet layer 20 inserted therein is completely visible, and coloration may be performed in colorless or light colors. In order to make the content printed on the sheet layer 20 more clearly visible, it is preferable to make the polyurethane resin more transparent and soft.

The shaft 10 inserted into the cavity 400 of the transparent layer 40 is firmly joined by an adhesive. The adhesive bonding the shaft 10 and the transparent layer 40 may be formed by applying an adhesive in a sheet state such as a double-sided tape or a liquid adhesive to form an adhesive layer 31, and the adhesive layer 31 may be a coating layer. It may be selectively formed on the surface of (30,30 ') or the inner peripheral surface of the transparent layer 40.

Immediately after the adhesive layer 31 is formed, the shaft 10 is immediately inserted into the transparent layer 40 so that the adhesive layer 31 formed on the surface of the coating layer 30, 30 ′ or the inner circumferential surface of the transparent layer 40 is formed. By the shaft 10 is not inserted until the end of the cavity 400 is bonded and hardened in the middle. Therefore, before inserting the shaft 10 into the cavity 400 of the transparent layer 40, a highly volatile solvent such as thinner or the like is sprayed or applied onto the inner circumferential surface of the adhesive layer 31 or the transparent layer 40. The viscosity of the adhesive layer 40 is temporarily lowered so that it can be inserted smoothly.

When the shaft 10 smoothly inserted into the cavity 400 of the transparent layer 40 by the sprayed or applied solvent 50 is left for a predetermined time, the solvent 50 is evaporated to form an adhesive layer. 31 is hardened, and the shaft 10 is fixed to the transparent layer 40 together with the sheet layer 20 and the coating film layer 30 so that the position thereof is not changed or damaged even in the impact caused by the movement. It is firmly coupled so that it can be maintained.

Golf clubs of the present invention is formed in such a structure is transparent, the golf clubs are summarized with reference to Figure 3, first, by applying an adhesive around the end of the shaft 10, a sheet for printing promotional pictures, pictures, figures, letters ( 20) by attaching and forming a coating layer 30 thereon, or by applying a transparent thin vinyl coating on the surface of the pre-printed sheet to prepare a sheet layer 20 having the coating layer 30 already formed shaft 10 After adhering to the end, the adhesive layer is sprayed again or the sheet-like adhesive is laminated thereon to form the adhesive layer 31, and after spraying or applying the highly volatile solvent 50, the transparent layer with the cavity 400 After inserting the 40 and drying for a predetermined time, the transparent layer 40 is firmly fixed around the shaft 1 together with the sheet layer 20 and the coating layer 30.

Therefore, the grip of the present invention is a transparent golf club, the solvent layer 50 is not absorbed into the sheet layer 20 by the coating film layer 30, so that the printed portion without any stains or smears appeared clearly and intended aesthetics This expression has been sufficiently expressed. In particular, the sheet layer 20 made of an elastomeric material has a higher grip and shot feeling as well as a shock absorbing effect. In addition, the coating layer 30 may be inserted into the transparent layer 40 smoothly by the adhesion of the surface of the coating layer 30 can be more firmly bonded.

As described above, the golf club that is transparent in grip according to the present invention forms a transparent and thin coating layer on the printed sheet layer, so that there is no stain or bleeding on the surface of the sheet layer, and the printed contents are not deformed or distorted and semi-permanently. As a result, the quality of the sheet layer embedded in the transparent grip can be improved.

In addition, the grip of the present invention according to the transparent golf club grip, the grip layer and a thin transparent coating film layer formed with a plurality of minute projections using an elastomer material inserted into the grip to increase the grip and hitting feeling and to reduce the impact to improve the swing feeling It works.
