Description

Transparent grip for tennis racket with a damping layer}

The present invention relates to a transparent tennis grip grip, and more specifically, to a transparent tennis grip that can be seen from the exterior of the grip is embedded in the print for promotional purposes such as photographs or pictures.

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

The grip formed by the cladding method of the cladding requires a lot of labor and the phenomenon that the cladding prepared by the factors such as the winding force, the winding position and the spacing remains or falls short even when the cladding is prepared and wound in a suitable length in advance. This has happened frequently. Therefore, in recent years, many moldings have been applied that are formed to have unevenness integrally with the surface of the grip to increase gripping force and to be excellent in elasticity without being slippery.

Since the tennis 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 tennis 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 the promotional letter or figure such as the company logo or brand name.

As such, it takes a lot of money to produce a tennis club grip 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. There was no. Therefore, when the public or the government wants to present or donate a tennis body to commemorate a competition or a special event, the meaning of various competitions or events may be attached by attaching a sticker printed with commemorative pictures or letters on the surface of the grip Used to express.

However, in this case, the sweat of the hand gets stuck on the grip so that the sticker could not be stuck for a long time and quickly fell off, and at the same time, the adhesive on the back of the sticker was stuck on the hand, making the hand sticky, resulting in discomfort.

As the inventor has been engaged in this field for many years, if various printed matters are embedded inside the tennis grips to be viewed from the outside, it will not only produce the publicity effect of the production and sales company, but also include personal identity and memorial contents. In this case, the tennis club grip of the present invention was developed in consideration of the fact that it would be possible to prevent the loss of tenichae and to remember the meaning of the event for a long time.

That is, the present inventors apply the basic structure of the tennis club grip by breaking away from the existing typical type of tennis club grip, but by making the grip itself completely transparent to light, it is easy to make a specific picture or photo inside by a simple method. It provides a new structure of a transparent tennis grip that can be easily inserted, viewed from the outside, and retained almost semi-permanently.

According to the present invention, in a tennis club grip formed around the shaft end of a tennis club, the grip layer includes a damping layer covering the entire circumference of the shaft, a printing layer covering the entire circumference, or a portion of the light beam. It consists of a combination of transparent layers that can be completely permeable. The transparent layer is characterized in that the integral molded body of polyurethane resin having a cavity in the middle so that the shaft can be inserted.

The transparent layer is colored in various colors such as colorless or light red, yellow, etc., but is transparently formed so that the damping layer of the shaft inserted therein can be completely seen. Reaction, biscarbamic acid ester and glycol exchange reaction, diamine and ethylene carbonate or bisurethane and diamine, etc., which are two kinds of ordinary polyether and polyester type polyurethane resins 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 printing layer and the transparent layer are fixed to each other in whole or in part by a common sheet or liquid colorless transparent adhesive, and the printing layer is used for commemoration for various sports events or world sports such as the World Cup. Photographs, logos or figures representing the name of the manufacturer and / or distributor, or printed matters containing the address or name of the individual are used as the surface, and an adhesive site or a liquid adhesive is applied on the back surface.

Referring to the accompanying drawings to more clearly understand the structure of the transparent tennis club grip according to the present invention is as follows.

1 and 2 are a cross-sectional view showing a perspective view showing the overall shape of the transparent tennis club grip according to the present invention and its internal structure, Figure 3 shows a state diagram of a transparent tennis club grip of the present invention. As shown in Figs. 1 and 2, the tennis club grip G according to the present invention has a cavity 5 of a suitable size into which the end of the shaft 1 can be inserted as usual and is artificial with the shaft 1; Firmly combined so that no separation is possible.

That is, the grip G is a cylindrical body having a cavity 5 having a circular cross section therein, which is integrally formed by a polyurethane resin, and the shaft 1 inserted into the cavity 5 is externally formed. It consists of a transparent layer 4 which completely transmits light to the extent that it can be seen and a printing layer 3 provided on the inner surface thereof.

Since the transparent layer 4 is formed of a polyurethane resin having a moderate elasticity and high friction resistance, the feel is good and not slippery when gripping, but may be integrally formed so that the surface has small unevenness as needed to further increase the gripping force.

An adhesive layer is provided between the transparent layer 4 and the printing layer 3. The adhesive layer is slightly larger than the size of the printing layer 3, and may be formed by an adhesive in a conventional sheet state or may be formed by applying a liquid adhesive.

The printed layer 3 is printed with advertisements such as photographs representing special events or tourist attractions, trade names or trademarks of producers or distributors, and addresses or names that may indicate possession of other specific persons. The print layer 3 is located inside the grip G so that it can be identified from the outside through the transparent layer 4.

Beforehand. When the printed layer 3 is prepared by setting the printed layer as a surface layer, the adhesive layer coated with the shaft 1 and the release paper covering the adhesive coating layer are bonded to each other, and the print layer 3 is prepared. If only removed, the printing layer 3 can be easily adhered to the shaft 1 and can be conveniently applied.

In addition, the printing layer 3 may be formed so as to cover only the entire circumference or part of the end of the shaft 1 as desired. An adhesive layer joining the print layer 3 and the transparent layer 4 is provided to cover the entire inner surface of the transparent layer 4 so that the size of the print layer 3 is located between the shafts 1. As they become more firm.
