Abstract

PROBLEM TO BE SOLVED: To provide a protective band for a grip to prevent a user from slip ping. SOLUTION: This protective band has a first belt-like body 12 and second belt-like body 14 which vary in the properties of their front surfaces. The first belt-like body 12 has the smooth surface. The second belt-like body 14 has the rough surface having ruggedness. A second lateral edge 12d is connected to a third lateral edge 14c. A first inside surface 12a and a second inside surface 14a are adhered to the grip and are installed by spirally winding the surfaces to the grip. Many granular materials 14' are mixed or fastened to a second outside surface 14b and therefore the second outside surface is roughly formed to have a large coefficient of friction. Consequently, the slip of the user's hand does not occur.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective band for a grip used for a grip of a ball game device.

[0002]

2. Description of the Related Art Conventionally, a protective band for grip of a ball game device such as a tennis racket, a badminton racket, a golf club, etc. is formed of natural leather or artificial leather. As disclosed in US Pat. No. 5,695,418, a protective band made of artificial leather has a non-woven bottom layer, and the bottom layer has a top layer formed by coating with polyurethane (PU). . Since the upper layer of the PU has a high elastic modulus, the shock when hitting the ball is absorbed, and the user can grip the grip comfortably. Also, as disclosed in U.S. Pat. No. 5,857,929, two differently colored bands are provided to form grip guard bands having different colors.

[0003]

However, since the mechanical performance such as the coefficient of friction or the elasticity of the surface of the conventional grip protective band is uniform, different feelings cannot be provided when different parts are gripped. Further, the upper layer of the PU has a flat and smooth surface that is hard to absorb sweat, so that the grip protection band is easily slipped from the user's hand. Therefore, an object of the present invention is to provide a grip protective band which has a surface having a different friction coefficient depending on a part and is hard to slip from a user's hand.

[0004]

According to the protective band for a grip of the present invention, a first band and a second band are provided. The first band includes a smooth first outer surface, a first inner surface, and a first inner surface.
It has a side and a second side. The second band has a second outer surface having a larger coefficient of friction than the first outer surface, a second inner surface, a third side, and a fourth side. The second side is third
Connected to the side. The first inner surface and the second inner surface are adhered to the grip, and the grip protection band is spirally wound around the grip and installed. Since the second outer surface of the second belt-like body is mixed with a large number of particulate substances, the second outer surface has a large friction coefficient and is formed roughly. Therefore, it is possible to prevent the grip protection band from slipping on the user's hand.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, a grip protection band 10 according to an embodiment of the present invention is used by being spirally wound around a grip 11 of a ball game tool.
The grip protection band 10 includes a first band 12 and a second band 1.
4, a wire 16 and a double-sided tape 18 are provided.

[0006] The first band 12 is made of polyvinyl chloride.
It is formed by foaming a polymer such as nylchloride (PVC), ethylene-vinyl acetate copolymer (EVA), or polyurethane (polyurethane: PU). The first belt-shaped body 12 has a first inner surface 12a, a first outer surface 12b, a first side 12c and a second side 12d having a predetermined slope.

[0007] The second band 14 includes a large number of particulate substances 14 '.
Is mixed and foamed to form a polymer such as PVC, EVA or PU. The second band 14 has a second inner surface 14a, a second outer surface 14b, a third side 14c and a fourth side 14d having a predetermined slope. The particulate material 14 'is a rubber granule formed by crushing dried rubber, and has an uneven outer contour. The second band 14 is formed by mixing a particulate material 14 'with a polymer, and has a granular and rough surface. For this reason, the friction coefficient of the second belt-like body 14 increases. The granular material 14 'is not limited to rubber, but may be plastic or another material having elasticity.

A wire 16 is inserted between the second side 12d of the first band 12 and the third side 14d of the second band 14 at predetermined intervals in the longitudinal direction of the grip protection band 10. The second side 12d and the third side 14d are connected.

The double-sided tape 18 has a first adhesive surface 18a and a second adhesive surface 18b. The second adhesive surface 18b is covered with a peelable protective paper 18d. As shown in FIGS. 2 and 3, the first adhesive surface 18a of the double-sided tape 18 is adhered to the first inner surface 12a and the second inner surface 14a. The protective paper 18d is peeled off, the second adhesive surface 18b is adhered to the surface of the grip 11, and the protective band 10 for grip is set on the grip 11 of the ball game tool.

First outer surface 12a and second outer surface 14a
Have different properties such as coefficient of friction, modulus of elasticity and wear resistance. For this reason, the grip protection band 10 is hard to slip from the user's hand. Further, the disadvantage that the surface of the conventional grip protective band is flat and smooth and has a low coefficient of friction is also improved. Therefore, it is possible to provide the user with a different gripping feeling depending on the part. In addition, the first belt-like body 12
If a granular material 14 ′ having a different color from that of the second band 14 is used, a grip protection band of various colors is formed.

As shown in FIG. 5, a protective band for a grip according to another embodiment of the present invention includes a first band 42 and a second band 44. The first belt-like body 42 is the first
It has an inner surface 42a, a first outer surface 42b, a first side 42c, and a second side 42d. Further, the first belt-shaped body 42 is formed of a bottom layer 42e and an upper layer 42f. Bottom layer 42
e is formed from a plurality of non-woven fibers and has a first inner surface 4
2a and an upper surface 42g. The upper layer 42f is formed by applying a PU mixture to the upper surface 42g of the bottom layer 42e, foaming, aging and drying the mixture.

The second strip 44 has a second inner surface 44a,
An outer surface 42b, a third side 44c, and a fourth side 44d are provided. The second belt 44 has the same structure as the first belt 42, and a large number of particulate substances 44h are mixed in the upper layer 44f. The third side 44c of the second strip 44 and the second side 44c
The second side 42d of the band 44 is adhered with an adhesive.

As shown in FIG. 6, a grip protection band 60 according to another embodiment of the present invention includes a first band 62 and a second band 64. The first belt-shaped body 62 is formed by soaking a body 70 formed of a woven or non-woven material in a mixed solution of PU, and foaming, aging and drying the mixed solution. Since the main body 70 is installed inside the first belt-shaped body 62 of PU, the first belt-shaped body 62 has excellent strength and can prevent breakage and cracking.

The second band 64 has the same structure as the first band 62. The second strip 64 has a second outer surface 64a.
Since a large number of particulate matter is fixed to the second belt-like body 6
4 has a rough surface.

[0015] The density and thickness of the distribution of particulate matter on the outer surface of the strip affects the feel and frictional force of the user's hand. When granule size particulate material passing through a No. 30 mesh sieve screen is used, it provides a comfortable gripping feel and excellent frictional force. Further, the structure of the first band and the second band can be freely selected from the three different embodiments described above, and various mechanical performances can be selected by connecting the first band and the second band.
