DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective band, and more particularly to a protective band for a racket handle in a ball game.

[0002]

2. Description of the Related Art Conventionally, a protective band wound around a handle of a racket is generally formed by coating a bottom layer of a non-woven cloth with an upper layer made of a material called polyurethane (PU). Due to the characteristic of the high elastic coefficient of the PU upper layer, the vibration that appears while the user is hitting the ball is absorbed.
However, since the PU upper layer has a smooth surface and excellent moisture-proof properties, when the PU upper layer gets wet with the sweat of the user's hand, the space between the user's hand and the protective band is slippery and easily falls off. In severe cases, the user may have to use the racket handle with greater force to prevent the user from slipping off after using the protective band for a long period of time. Absorber action is greatly reduced.

[0003]

In order to remedy the drawbacks mentioned above, existing technologies include a fair design of a non-slip protective band. For example, one side of the PU upper layer of the protective band is processed to a rough hairy flannel-like surface, or one side of the PU upper layer of the protective band is polished until there is a cutout. Unfortunately, these methods achieve a non-slip purpose with a non-slip surface having a high coefficient of friction, primarily by polishing or processing the PU top layer of the product. In the end, the secondary processing of polishing the product is complicated and inconvenient.

[0004] In addition, existing technology attaches a narrow and elongated protruding rib in the center of the bottom layer of the protective band. When such a protective band is wrapped around the handle, it becomes a protruding surface, and the effect of preventing slippage when gripping is improved. However, as the existing technology that projects only at the center of the protective band, the effect of the anti-slip is not only limited, but also the grip of the user's hand is poor. In view of this, the inventor has actively researched and developed based on his experience of actively engaged in correlated work for many years, and has finally developed the present invention.

Accordingly, it is a primary object of the present invention to provide a protective band for a handle having a shock-absorbing and anti-slip effect.

[0006]

In order to achieve the above-mentioned object, the protective band of the present invention is formed from the following elements. The fabric layer of the base has a top surface and a bottom surface. Adhere the bottom to the racket handle. The top rare adheres to the upper surface of the base fabric layer. At the top rare, at least a shock absorber stage and a non-slip stage are installed at intervals.
The shock absorber stage is formed from a material such as polyester, and the non-slip stage is formed by mixing a number of granules and an adhesive. The protective band then helps the shock absorber and the anti-slip effect, respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. First, as shown in FIGS. 1 and 2, a protective band 100 according to a first embodiment of the present invention is formed from a base fabric layer 10 and a top rare layer 20.

The base fabric layer 10 is made of a non-woven fabric material and has a top surface 11 and a bottom surface 12. Bottom 1
Adhere 2 directly or with an adhesive to the handle of the racket. Of course, the base fabric layer 10 may be made of a general woven fabric or a cloth material of another material.

The top rare 20 is adhered to the upper surface of the base fabric layer 10 so as to lay flat. Also, Top Rare 2
At 0, several anti-slip steps 21 and shock absorber steps 22 are installed at intervals.

Each non-slip step 21 is formed by mixing a plurality of granules A and a resin adhesive, and then painting each shock absorber step 22. In this example, the granular material A
Is a rubber granule formed by crushing a dry rubber material. After folding as a plurality of layers using the shape whose outer contour is not regular, the surface of the non-slip step 21 is roughened and processed to a state of “unevenness unevenness”. Of course, the granules A may be made of plastic granules or another slightly elastic material.

Each of the shock absorber stages 22 is made of a mixed liquid of polyurethane (PU) containing polyester, applied to the cloth layer 10 of the base, and formed with protruding ribs such as an interval arrangement. Moreover, the surface of each shock absorber stage 22 is slightly lower than the surface of the non-slip stage 21. The above is the description of the structure and the relative positions of the protection band 100 according to the first embodiment of the present invention. Subsequent examination of the production reveals its structure, features and advantages.

When manufacturing the protective band 100 according to the first embodiment of the present invention, first, the base fabric layer 10 is left on a conveyor and is constantly transported forward. At the same time, the upper surface is passed through a coating tank (not shown), and polyurethane (PU) containing polyester is applied on the upper surface. Thus, after drying, a PU layer is formed. Next, P
A number of parallel concave grooves are machined through a molding die in which the U layer has a zigzag shape. Between each groove, a shock absorber stage 22 is formed. Then, a granular material A mixed with an adhesive is applied to the groove. After drying, a non-slip step 21 is also formed. The upper end of the granular material A protrudes and is exposed from the surface of the shock absorber stage 22. Then, a non-slip surface called “unevenness unevenness” is formed, which improves the shock absorber effect and the friction coefficient.

As the protective band 100 for the handle, which is assembled in such a fine manner, the manufacturer employs granules A having different sizes according to needs, and produces the top rare 20 having a different coefficient of friction. After a number of tests, the inventor finds that the granules A of size 60 mesh are the best, providing a suitable grip and friction in the user's hands. Also, the granularity A of each anti-slip step 21 has a little elasticity,
Is polyurethane containing polyester (polyurethane, PU)
The protective band 100 for the handle, which is made from the same, provides the user with a great shock absorber effect. In short, the handle guard 100 provides a great anti-slip and shock absorber effect.

FIG. 3 shows a guard band according to a second embodiment of the present invention. The protective band 200 for the handle is applied to the upper surface 31 of the base fabric layer 30 by applying a granular material A mixed with an adhesive,
A top rare 40 is formed. The top rare 40 has a non-slip step 41 having a number of ribs, such as a single piece.
Is formed. Also, a shock absorber stage 42 is formed after filling a mixed liquid of polyurethane (polyurethane, PU) between the neighboring non-slip stages 41 and drying.
Then, a protective band for the shock absorber and a handle having an anti-slip effect is completed. Since the bottom of the non-slip step 41 having a number of granular materials A directly contacts the upper surface 31 of the base cloth layer 30 which is not a woven fabric, the sweat coming out of the user's hand causes each granular material A penetrates into the cloth layer 30 of the base via the gap of A and is sucked. After all, the anti-slip effect is fully exhibited.

FIG. 4 shows a guard band according to a third embodiment of the present invention. The protective band 300 for a handle has a top rare 60 laid flat on the upper surface 51 of the base fabric layer 50. A number of anti-slip steps 61 and shock absorber steps 62 are arranged on the top rare 60 so as to be spaced apart. Since their bottoms are in direct contact with the upper surface 51 of the base fabric layer 50, they have the effect of preventing slippage and shock absorption and also have a good sweat absorbing effect.

In summary, the present invention has inventive step, practicality, and convenience in use as compared with similar products.
However, what has been described above merely shows three ideal embodiments for explaining the present invention, and the present invention is not limited in any form. Therefore, in the same spirit as the present invention, all equivalent structures, improvements and modifications are included in the protection scope of the present invention.
