Abstract

PROBLEM TO BE SOLVED: To provide a protective strip of a handle with anti-slipping granules on the surface thereof. SOLUTION: The protective strip 10 which is wound spirally on a handle 11 for ball game contains a strip body 12 and numerous grainy matters 14. The strip body 12 is molded by expanding polymer material such as PVC, EVA or PU and has internal and external surfaces. Long narrowly recessed parts are arranged at intervals along the longitudinal direction of the external surface of the strip body. The strip body 12 thus obtained is spirally wound and tightened on the handle 11 and a user holds the external surface of the strip body 12. The grainy matters 14 are the granules of rubber formed by crushing dry material of rubber and the outer contour thereof has an irregular shape. The grainy matters 14 are fastened into the recessed parts of the external surface of the strip body to improve the degree of the ruggedness and the elasticity of the recessed parts in the external surface. This can prevent slipping off the hand when the user holds the external surface of the strip body 12 with a hand while a different touch is given when the user holds the external surface of the strip body 12 at different positions thereof.

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. It is still another object of the present invention to provide a protective band that has different surface friction coefficients at different positions and gives the user various grip feelings.

[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. The outer surface has at least one recess.
A number of granules are adhered at predetermined locations on the outer surface of the band. Then, the roughness of the position of the concave portion on the outer surface is improved, and the user is prevented from sliding down while holding the outer surface of the band-shaped body.

[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
lyvinyl chloride), ethylene vinyl acetate (E
VA (ethylene-vinyl acetate copolymer) or polyurethane (PU: polyurethane)
mer) It is molded by foaming from a material and has an inner surface 16 and an outer surface 18. At each of the two side edges, there is a deleted inclined side 20. Three elongated recesses 18 a are provided at intervals along the longitudinal direction of the outer surface 18. When the band 12 is used, the inner surface 16 is spirally wound around the handle 11 directly or after applying an adhesive or applying a double-sided tape (not shown), and tightened. The user then grips the outer surface 18 of the web 12.

Each granule 14 is a rubber granule formed by crushing a dry rubber material, and has an irregular outer shape. After mixing the granules 14 with an adhesive such as a resin, the granules 14 are applied to the recessed portions 18 a of the outer surface 18 of the strip 12. After the adhesive is dried, the granules 14 adhere to the concave portions 18a of the outer surface 18 and improve the roughness and elasticity of each concave portion 18a of the outer surface 18. Therefore, when the user grasps the outer surface 18 of the band 12 by hand, it is possible to prevent the user from slipping down, and to provide different feelings when the user grasps different positions on the outer surface 18 of the band 12. Of course, the actual use of the granules 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, distribution densities, and stacks where each granule is located in the recess 18a of the outer surface 18 of the strip 12. By changing the thickness of the fold, 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 set in a concave portion (not shown) of the outer surface 18 of the belt-like material 12. It becomes a design of the planned shape. Then, the user holds the protection band 10 by hand.
In addition to having a different coefficient of friction while contacting the different locations, the disadvantage that the protective band conventionally has a flat surface, a smooth and non-coincident coefficient of friction is ameliorated.

(Third Embodiment) As shown in FIG. 4, a protective band 40 according to a third embodiment of the present invention includes a band 42 and a number of granular bodies 44.

The strip 42 has an inner surface 46 and an outer surface 48. That is, the strip 42 is composed of the bottom layer 50 and the upper layer 52. The bottom layer 50 is made of a non-woven fabric formed from a number of bundled fibers and has an inner surface 46, an upper surface 5
4 inclusive. The upper layer 52 is formed by applying the mixed solution of PU to the upper surface
4 and formed after the mixture is foamed, aged and dried. On the outer surface 48, three concave portions 48a are formed by a mold.
Are molded by heating and pressing so as to leave an interval. The respective granular bodies 44 are stacked on each other, and filled and fixed in the recessed portions 48a.

(Fourth Embodiment) As shown in FIG. 5, a protective band 60 according to a fourth 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 third 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. Since the main body 70 of the cloth is inside the band 62 made of PU, the band 62 has excellent fine strength.

[0016] Except for filling each granular material 64 into the concave portion 68a of the outer surface, it is directly applied to the center position of the outer surface 68 and stacked. The outer surface 68 has a stepped head having a predetermined height. As a result, the contour change of the outer surface 68 of the strip 62 is increased.

The important points to be described in particular are 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 No. 30 mesh knot network, or if the granular materials are stacked on each other, a drop formed on the outer surface of the band is 0.5 mm. If it is smaller, it is found that the user's hand grip comfort and abrasion force reach an excellent equilibrium state.

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.
