EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the form (henceforth "embodiment" is called) for implementing this invention is demonstrated in detail. The same numbers or symbols are given to the same elements throughout the description of the embodiments.

A method of attaching a grip 1 of a product 2 having a grip portion according to this embodiment will be described with reference to FIG. In this embodiment, a golf club will be described as an example of the product 2 having a grip. However, the product is not limited to golf clubs.

(Step S1)
First, in step S1, a product 2 having a grip portion (hereinafter sometimes simply referred to as "product") and a grip 1 having a shaft hole therein are prepared (step (A)). The product 2 having a grip portion is not particularly limited as long as it has a grip portion that can be gripped by the palm of the user. Bicycles, ski poles, sporting goods such as golf clubs, work tools such as sickles and files, and kitchen tools such as kitchen knives and ladle. Sporting goods are preferable as products for which the grip attachment method of the present invention is used, and golf clubs are preferable as the sporting goods.

FIG. 3 is a side view of a product 2 having a grip portion and a grip 1 according to this embodiment, and FIG. 4 is a sectional view taken along line II-II of FIG. The grip portion of the product (golf club) is a tubular body, and the other end opposite to the one end to which the grip 1 is attached is connected to the golf club head (not shown). The grip 1 also has an inner hole into which the product 2 having a grip is mounted, and the inner hole has a shape, for example, a circular cross section, adapted to the product 2 having a grip.

Materials for the product 2 having a grip include conventionally known materials such as fiber reinforced resin (FRP), metal materials such as aluminum and steel, wood, and combinations of these materials. In addition, the material of the grip 1 is a conventionally known material in combination with the product 2 having a grip portion, for example, leather materials such as fiber materials, synthetic leathers, natural leathers, rubber, elastomers, synthetic resins, thermoplastics, etc. Examples include elastic materials, fiber-reinforced elastic materials, and combinations of these materials. Also, the grip 1 may be covered with a foamed elastic body having water absorption and cushioning properties. The grip 1 can be molded by a conventionally known manufacturing method.

(Step S2)
Next, in step S2, an adhesive tape 3 having a plastic base material and a removable adhesive layer formed on the plastic base material is attached to the grip portion of the product 2 (step (B)). By providing the adhesive tape 3 having a removable adhesive layer between the grip part of the product 2 and the double-sided tape 4, the adhesive residue of the double-sided tape 4 is not left on the grip part of the product 2, and the product 2 is improved. It is possible to easily re-peel from the surface of the grip portion of the grip, improving the workability of replacing the grip. Further, as will be described later, since the double-sided tape 4 is stuck on the adhesive tape 3, it is not necessary to use different types of double-sided tape 4 depending on the material of the grip, which improves the workability when attaching the grip.

The method of attaching the adhesive tape 3 is not particularly limited, and conventionally known methods such as a method of spirally winding the adhesive tape 3 and a method of vertically attaching it to the grip portion of the product 2 can be used. The adhesive tapes 3 may or may not have a gap, but it is preferable to stick them without a gap so that the adhesive layer of the double-sided tape 4 does not come into contact with the grip of the product 2 .

The plastic-based base material of the adhesive tape 3 is not particularly limited, and examples thereof include olefin-based resins, polyester-based resins, polyvinyl chloride-based resins, vinyl acetate-based resins, amide-based resins, polyimide-based resins, polyetheretherketone, Examples thereof include resin films such as polyphenylene sulfide. These resins may be used alone or in combination of two or more in the resin film used as the plastic base material. The resin film may be a laminated body in which a plurality of resin films are laminated, or may be a foamed body in order to prevent slippage when gripped and fit the hand for easy gripping. In addition, the resin film may be subjected to various treatments such as back surface treatment, antistatic treatment, and undercoating treatment, if necessary.

The thickness of the plastic base material is not particularly limited, and is preferably 10 μm or more and 500 μm or less, more preferably 12 μm or more and 200 μm or less, and even more preferably 30 μm or more and 70 μm or less.

Further, the removable adhesive layer of the adhesive tape 3 has a function of fixing the grip to the grip portion of the product 2, and can be peeled off from the grip portion of the product 2 without leaving an adhesive residue when the grip is replaced. If there is, there is no particular limitation, and it can be formed using a conventionally known removable pressure-sensitive adhesive. For example, adhesives such as rubber, acrylic, silicone, and polyvinyl ether are used. Among these, the acrylic pressure-sensitive adhesive is preferable because the adhesive force can be easily controlled. These adhesives can be used individually by 1 type or in combination of 2 or more types.

A removable pressure-sensitive adhesive can be obtained by blending other components as necessary. Other components include, for example, commonly used tackifiers, antioxidants, ultraviolet absorbers, light stabilizers, softeners, silane coupling agents, fillers, and the like. These may be used individually by 1 type, and may be used in mixture of 2 or more types.

In order to prevent the grip from slipping when using the product 2 and to prevent the adhesive from remaining on the grip when replacing the grip 1, the adhesive strength of the adhesive tape 3 is 1.0 N / 25 mm. 20.0 N/25 mm or less is preferable, and 1.5 N/25 mm or more and 20.0 N/25 mm or less is preferable. Adhesive strength means a value measured in accordance with JIS Z 0237:2009 180° peel adhesive strength measurement 30 minutes after application to a stainless steel (SUS) plate as an adherend. Specifically, in an environment of 23° C. and 50% RH (relative humidity), the removable adhesive sheet is cut into a width of 25 mm, attached to a stainless steel (SUS) plate, and pressed back and forth with a 2 kg roller. Then, 30 minutes after the SUS attachment, the adhesive sheet is peeled off from the SUS plate at a peeling speed of 300 mm/min, and the adhesive force is measured.

In addition, the pressure-sensitive adhesive tape 3 has a J.I. The ball tack value at an inclination angle of 30° according to the Dow method is preferably 10 or more. When the ball tack value is 10 or more, the sticking property of the adhesive tape 3 to the grip portion of the product 2 is improved, and the grip is less likely to shift when the product is used. The ball tack value is more preferably 12 or more from the viewpoint of more stably ensuring the sticking property of the adhesive tape 3 to the grip portion of the product 2 .

The thickness of the removable pressure-sensitive adhesive layer is not particularly limited. For example, the thickness after drying is preferably 1 μm or more and 200 μm or less, more preferably 10 μm or more and 100 μm or less.

The method of forming a removable adhesive layer on a plastic base material is not particularly limited. It is preferably formed by Specifically, it is obtained by coating and drying an adhesive resin composition on a plastic base material. Alternatively, the adhesive resin composition may be coated on a process film separate from the plastic base material, dried to form a film, and transferred onto the plastic base material.

Further, the adhesive tape 3 may be a so-called linerless type or non-separator type in which the surface of the plastic base material is an easy peeling surface, or a type in which a release film is laminated on the upper surface of the removable adhesive layer. However, the latter configuration is preferable in order to make the adhesive tape 3 and the double-sided tape 4 difficult to peel off. Examples of the release film include those having a release layer provided on the surface of a film substrate or a paper substrate. Examples of film substrates include various resin films such as polyethylene terephthalate, polybutylene terephthalate, polyethylene, polypropylene, and polyacrylate. Examples of the paper substrate include various paper materials such as polyethylene-laminated paper, polypropylene-laminated paper, clay-coated paper, resin-coated paper, glassine paper, and high-quality paper. In addition, the film base material and the paper base material may contain a filler such as a filler. Examples of the release layer include those containing release agents such as silicone, long-chain alkyl resins, and fluorine resins. The thickness of the release film is preferably a normal thickness, for example, 20 μm or more and 200 μm or less.

(Step S3)
Next, in step S3, on the adhesive tape 3 attached to the product 2 having a grip portion, a double-sided tape 4 having an adhesive layer on both sides of the substrate is further attached (step (C)). The double-faced tape 4 adheres to the adhesive tape 3 and the grip 1 to strongly fix the product 2 having a grip part and the grip 1.例文帳に追加The method of attaching the double-sided tape 4 is not particularly limited, and there are conventionally known methods such as a spiral winding method and a vertically attaching method on the product 2 having a grip portion.

The base material of the double-sided tape 4 is not particularly limited, and examples thereof include paper base materials such as the above-described plastic base materials, high-quality paper, coated paper, glassine paper, laminated paper, and the like. The resin film used as the plastic-based substrate may be one of these resins or a combination of two or more of them, and may be a foam. The substrate may be a laminate obtained by laminating a plurality of resin films and/or paper substrates, and may be subjected to the various treatments described above, if necessary.

Also, the double-sided tape 4 has a strong adhesive force so that the grip does not come off during use, and the adhesive force of the double-sided tape 4 is usually greater than the adhesive force of the adhesive tape 3 . The adhesive layer of the double-sided tape 4 is not particularly limited, and conventionally known adhesives can be used. For example, rubber-based, acrylic, silicone-based, and polyvinyl ether adhesives are used. . Among these, the acrylic pressure-sensitive adhesive is preferable because the adhesive force can be easily controlled. These adhesives can be used individually by 1 type or in combination of 2 or more types. Moreover, it can be obtained by blending the other components described above as necessary.

The thickness of the adhesive layer of the double-sided tape 4 is not particularly limited. For example, the thickness of each adhesive layer after drying is preferably 1 μm or more and 200 μm or less, more preferably 10 μm or more and 100 μm or less.

In addition, in order to perform the process (B) in step S2 and the process (C) in step S3 at the same time, it is also preferable to use a laminated tape in which the adhesive tape 3 and the double-sided tape 4 are laminated in advance. Instead of the steps (B) and (C), after the step (A) in step S1, the laminated tape is attached to the grip portion of the product 2 (step (BC)), thereby reducing the number of steps. Since it can be done by simplification, the workability at the time of attaching the grip is improved.

The method of forming the adhesive layer on the base material of the double-sided tape 4 is not particularly limited, and the method described above for the adhesive tape 3 may be performed.

Moreover, in order to protect the pressure-sensitive adhesive layer, a release film may be laminated on the upper surface of the pressure-sensitive adhesive layer and peeled off before use. As the release film, the same ones that can be used for the adhesive tape 3 can be used.

(Step S4)
Finally, in step S4, the grip 1 is inserted into the grip of the product 2 (step (D)). Since the adhesive layer of the double-sided tape 4 is exposed on the surface of the product 2 having a grip portion, it is preferable to insert the grip 1 carefully until it reaches a predetermined position on the product 2 having a grip portion.

Through the steps described above, the grip 1 is attached to the product 2 having a grip portion.

(Other embodiments)
In the description of the above embodiment, the configuration is made after the double-sided tape 4 is attached. However, not limited to this, in order to improve the workability of the step (D) of inserting the grip 1 into the grip portion of the product 2, a step of treating the volatile solvent and a step of volatilizing the volatile solvent are configured. good too. FIG. 2 is a flow chart showing a series of flows of a grip attachment method according to another embodiment of the present invention. The above configuration will be specifically described with reference to FIG.

(Step S14)
Between steps S3 and S4, as step S14, the inner hole of the grip 1 and/or the surface of the double-sided tape 4 is treated with a volatile solvent (step (E)). Here, treating the volatile solvent means attaching the volatile solvent using at least one method selected from the group consisting of atomization, spraying, immersion, injection and coating. By treating with a volatile solvent, the inner hole of the grip 1 and/or the surface of the double-sided tape 4 swell and become slippery, making it easier to insert into the product 2 having a grip. The amount of the volatile solvent to be treated varies depending on the treatment method, but it is sufficient if the inner hole of the grip 1 and/or the surface of the double-sided tape 4 are sufficiently wet.

The volatile solvent is not particularly limited, and examples thereof include alcohols such as methanol, ethanol, propyl alcohol and isopropyl alcohol; ketones such as acetone, methyl ethyl ketone and diethyl ketone; Hydrocarbon solvents; organic solvents such as silicones such as octamethylcyclopentasiloxane, decamethylcyclopentasiloxane, octamethyltrisiloxane and decamethyltetrasiloxane; and water. More specifically, white gasoline, trade name "Isosol" manufactured by Nippon Petrochemicals Co., Ltd., water, and the like can be mentioned.

(Step S15)
Further, after step S4, in step S15, it is left still for a predetermined time until the volatile solvent volatilizes (step (F)). By evaporating the volatile solvent, the product 2 having a grip portion and the grip 1 are firmly fixed. In the processes of steps S14 and S15, the volatile solvent may permeate into the re-peelable pressure-sensitive adhesive layer, resulting in a decrease in adhesive force and a possible cause of grip deviation. In the present invention, since the base material of the adhesive tape 3 is a plastic base material, the volatile solvent is less likely to permeate into the removable adhesive layer, and therefore the adhesive strength is less likely to decrease. The time required for the volatile solvent to volatilize varies depending on the type of volatile solvent and the treatment amount, but is usually preferably 1 hour or more and 24 hours or less.

As described above, according to the method of attaching the grip 1 of the present invention, the adhesive tape 3 having a removable adhesive layer is attached to the product 2, thereby using the double-sided tape 4 having a strong adhesive force. The grip 1, the double-faced tape 4 and the adhesive tape 2 can be easily peeled off collectively without leaving adhesive residue on the grip even when the grip 1 is being replaced, thereby improving workability when exchanging the grip 1.例文帳に追加

In addition, an adhesive tape 3 having a plastic base material and a removable adhesive layer formed on the plastic base material on the surface of the product 2 having a grip portion, and an adhesive layer on both sides of the base material and the base material. and a double-sided tape 4 having and are laminated in order, and the grip 1 is adhered by the double-sided tape 4. The workability when exchanging the grip 1 is improved.

A laminated tape obtained by bonding the adhesive tape 3 and the double-sided tape 4 is attached to the surface of the product 2 having a grip portion, and the grip 1 is attached via the adhesive layer of the double-sided tape 4. The grip 1, the double-sided tape 4, and the adhesive tape 2 can be easily peeled off together with the product 2 having a grip portion with a grip, and the workability when exchanging the grip 1 is improved.
