Description

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 wound around a handle of a ball game tool.

[0002]

2. Description of the Related Art As is well known, a protective band wrapped around a handle of a ball game tool such as an existing tennis racket, badminton racket, golf club, etc. is conventionally made by using natural leather or artificial leather.

A well-known protective band for a handle made of artificial leather is US Pat. No. 5,695,418.
As disclosed in U.S. Pat. No. 5,086,086, polyurethane (PU) is used to cover the bottom layer except that it has a non-woven bottom layer.
There is also an upper layer made of ne). Through the high elasticity characteristic of the PU upper layer, shock is absorbed when hitting the ball, thereby providing a comfortable grip feeling to the user. However, since the PU upper layer does not absorb sweat and has a flat and smooth surface, a phenomenon in which the PU always slides down while the user holds the protective band by hand occurs.

[0004]

In the existing technology, a non-slip structure has been introduced in order to improve the above-mentioned drawbacks. For example, one side of the PU upper layer of a certain protective band is polished like a rough hair cord surface, so that a remarkable friction action force comes out. Since the other protective band is polished on one side of the PU upper layer like a concave portion, the design of the concave portion improves the coefficient of friction between the user's hand and the protective band. Unfortunately, the two existing technologies described above add a processing step of polishing the completed protective band, which proves to be complicated and cumbersome. In addition, a narrow and long convex rib is attached to the center of the bottom surface of the other protective band, so that while the protective band is spirally wound around the handle, a spiral projecting contour is formed and grasped Increase the anti-slip effect when. However, since such PU upper layer surface is still flat and smooth, it can be said that the anti-slip effect is insufficient.

[0005] Accordingly, it is a primary object of the present invention to provide a handle guard with a surface having non-slip granules. It is another object of the present invention to provide a protective band that is fairly simple and easy to manufacture. Still another object of the present invention is to provide a protective band which is arranged at different places and exerts a different anti-slip effect.

[0006]

In order to achieve the above-mentioned object, the protective band of the present invention is mainly formed of the following elements. The strip is spirally wound around the handle. The strip has an outer surface that is gripped by the user's hand and an inner surface that is clamped to the handle. A number of granules are adhered at predetermined locations on the outer surface of the band. This improves the roughness of the outer surface and prevents the user's hand from slipping while holding the outer surface of the band.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) First, as shown in FIGS. 1 and 2, a protection band 10 according to a first embodiment of the present invention is spirally wound around a handle 11 of a ball game. The protective band 10 includes a band 12 and a number of granules 14.

The belt 12 is made of polyvinyl chloride (PVC: po
The inner surface 16 and the outer surface 18 are formed by foaming and molding from a vinyl chloride material. At each of the two side edges, there is a deleted inclined side 20. If used, strip 1
The inner surface 16 of 2 is spirally wound around the handle 11 and tightened directly or after applying an adhesive or applying a double-sided tape (not shown). The user then grips the outer surface 18 of the web 12. Practically speaking, the strip 12 is made of polyurethane (PU), ethylene-vinyl acetate (EVA).
For example, a polymer such as a copolymer may be employed, and foamed and molded.

Each granule 14 is a rubber granule formed by crushing a dry rubber material, and has an irregular outer shape. After the granules 14 are mixed with an adhesive such as a resin, the granules 14 are applied to predetermined positions on the outer surface 18 of the band 12. After the adhesive is dried, the granules 14 adhere to the outer surface 18 and the roughness of the outer surface 18 is improved. Therefore, when the user grasps the outer surface 18 of the band 12 by hand,
Prevent slipping. Of course, the use of the granular material 14 may be made of plastic or another material having elasticity, and is not limited to rubber.

In the above-described assembly, the manufacturer may employ granules of different cheek grain sizes or different locations where each granule is located on the outer surface 18 of the strip 12, distribution density,
By changing the stacking thickness, the roughness and characteristics of the outer surface 18 of the strip 12 can be controlled.

(Second Embodiment) As shown in FIG. 3, in a second embodiment of the present invention, the granular material 14 is provided only at a certain step on the outer surface 18 of the strip 12, and the remaining portion is The original state is maintained as it is.

(Third Embodiment) As shown in FIG. 4, in a third embodiment of the present invention, the granular material 14 is installed on the outer surface 18 to obtain a pattern having a predetermined shape. Then, while the user is touching different positions of the protective band 10 by hand,
As well as having different coefficients of friction for contact, the disadvantages of the conventional protective band having a flat surface, a smooth and non-coincident coefficient of friction are alleviated.

(Fourth Embodiment) As shown in FIG. 5, a protection band 40 according to a fourth embodiment of the present invention comprises
It includes a number of granular bodies 44. The band 42 has an inner surface 46 and an outer surface 48. That is, the belt-like body 42 has
It is composed of an upper layer 52. The bottom layer 50 is made of a non-woven fabric formed from a number of bundles of fibers and includes an inner surface 46 and an upper surface 54. The upper layer 52 is formed after a mixed solution of PU is applied to the upper surface 54 of the bottom layer 50 and the mixed solution is foamed, aged, and dried. Each granular body 44 is stacked on each other and fixed to the outer surface 48, and has a certain thickness.

(Fifth Embodiment) As shown in FIG. 6, a protective band 60 according to a fifth embodiment of the present invention includes a band 62 and a number of granular objects 64. The difference between the handle protection band 60 and the fourth embodiment described above is as follows.

The strip 62 has an inner surface 66 and an outer surface 68. The strip 62 is taken out after impregnating the cloth body 70 (woven cloth or non-woven cloth) with the PU mixed solution. After the mixture is foamed, aged and dried, it is integrally molded. Therefore, the belt-shaped body 62 has excellent strength, and while being wound around the handle of a ball game tool such as a golf club or a tennis racket, the belt 62 is damaged,
Cracking phenomenon is unlikely to occur.

An important point to be particularly described is as follows. The density and thickness at which the granular material is distributed on the outer surface of the belt directly affect the comfort of the user's hand grip and the rubbing force. According to various tests by the inventor, if the granular size is a granular size passing through a mesh mesh No. 30 or if the thickness of each granular material stacked on each other is less than 0.5 mm, the grip of the user's hand is comfortable. It is found that the feel and the rubbing force reach a good equilibrium.

To summarize the above, according to the present invention,
The grip guard with the provided anti-slip effect certainly improves the disadvantages of the prior art. Its practicality and inventiveness need not be questioned.
