[Technical field to which the invention belongs]

 The present invention relates to a golf club grip formed of a grip material mixed with an antibacterial agent.

[0002]

[Prior art]

 As is well known, a golf club (club) mainly includes a head, a shaft, and a grip. In particular, the grip is an important part that not only functions as a simple gripping part of the club, but also functions to eliminate looseness so that the club can be firmly gripped and to reduce the impact of impact of the ball. It is. In addition, since golf is a mental sport, the feeling of gripping and swinging is very important for the owner.

[0003] The grip may be replaced due to abrasion, accidental scratching, or a change in feeling due to long-term use of the golf club. Generally, the grip is wound on a suitable base material such as an adhesive tape provided at the tip of the shaft, for example, by winding a tape-shaped grip material, press-fitting the grip material integrally molded in a substantially cap shape, Outsert molding. The grip is made of, for example, a rubber material obtained by mixing leather or natural rubber with a synthetic rubber such as EPOM or SBR, or a synthetic resin material such as a urethane resin. As the grip, a so-called corded grip formed by dispersing a non-slip code made of cotton or the like on a grip material is also provided.

[0004] By the way, the club is a basic item of a golf game, and various improvements have been conventionally made on each part such as a head, a shaft, and a grip in order to achieve a higher score. In particular, with regard to the improvement of the grip, the main point has been focused on the development of a material that improves the feel, the sliding degree, the weight, and the like under the predetermined standard conditions, and the shape thereof.

[0005]

[Problems to be solved by the invention]

 Clubs are usually owned by their owners, except for rental clubs such as practice ranges. Many owners take care of their favorite clubs to carefully remove mud and dirt from the heads and shafts and to prevent rust. At each golf course, after the play, the above-mentioned care service is provided for the customer's club. However, even such owners generally do not pay much attention to grips, and at best, only lightly wipe them. The grip is generally provided with fine irregularities to prevent slippage, and there is a tape-like winding step, so it is extremely difficult to clean every corner.

[0006] The club also requires sufficient care of the grip portion, especially in summer or after rainy play, because sweat, rainwater, and the like on the hand penetrate the grip. If the club has been kept in this state for a relatively long time without using the club, the grip often becomes moldy. In particular, corded grips are susceptible to mold and the like due to poor drying of the cotton material.

[0007] In a club, if sweat or the like is still infiltrated into the grip, mold and germs are generated on the grip of the part to be gripped by hand, although other people rarely use the grip. And there is a problem in hygiene. The owner sometimes wipes the grip wet with sweat or rain with a towel, etc. on the course or in the practice area with a towel prepared for wiping sweat on the face, etc. It may adhere directly to the mouth, eyes, nose, etc.

[0008] Further, the clubs are housed in the golf bag with the grip side facing down. Since the golf bag is manufactured to have sufficient water resistance and water repellency, the air permeability inside the golf bag is poor. Therefore, when the club is stored in the golf bag for a long time in the above-described state, mold and various germs are more likely to occur and propagate, and the club is not only unsanitary but also deteriorates in durability due to corrosion and the like. There is a problem.

By the way, in many recent products, a silver-based antibacterial agent which is harmless to the human body is mixed with a material to produce a hygienic product. For clubs, adding antibacterial function to the grips can reduce the above-mentioned germs and mold, improve hygiene, and improve durability. Clubs with antibacterial functions added to the grips must be manufactured to meet strict standard requirements, maintain their productivity, and maintain their antibacterial action for a relatively long period of time. The development environment has not yet sought a grip that would clear these. The antibacterial effect is added to the grip by applying an antibacterial agent, for example, by spraying, but the function is impaired by using such a countermeasure.

On the other hand, a grip having an antibacterial function is considered to be formed by a grip material mixed with an antibacterial agent, but it is necessary that the antibacterial agent is uniformly dispersed throughout the raw material. When the antibacterial agent is not evenly dispersed in the raw material, the grip has a problem that it hardens inside and does not reach the surface portion to be gripped, so that sufficient antibacterial action cannot be performed. However, the grip material is improved in dispersibility of the antibacterial agent by kneading sufficiently with a roll while adding the antibacterial agent to the raw material. A problem arises in that the required soft fit is impaired.

[0011] In addition, in order for the grip containing an antibacterial agent to sufficiently exhibit an antibacterial function, it is considered to increase the amount of the antibacterial agent added or to use an antibacterial agent having a higher antibacterial action. However, increasing the amount of antibacterial agent causes problems such as deteriorating the properties of the grip material. In addition, antibacterial agents having high antibacterial activity generally have high toxicity, so that there is a problem in using them for grips held directly by hand. Since a highly safe antibacterial agent generally has a low antibacterial effect, it is necessary to disperse the antibacterial agent uniformly on the surface of the grip as described above so that the antibacterial function is sufficiently exerted.

Therefore, the present invention is made of a material mixed with an antibacterial agent, so that the characteristics are not impaired, the generation of mold and the like is suppressed, and hygiene is taken into consideration, or the durability is improved. It has been proposed for the purpose of providing a grip for a golf club.

[0013]

[Means for Solving the Problems]

 The golf club grip according to the present invention, which achieves the above object, has an antibacterial agent comprising ultrafine silver supported on a titanium oxide-based ceramic in a grip material such as a rubber material or a synthetic resin material. It is formed of a grip material mixed at a ratio of from 1.5% by weight to 1.5% by weight.

Further, the grip for a golf club according to the present invention has a sheet layer on which a non-slip cord is mixed, and oxidizes ultrafine silver on the non-slip cord and / or sheet layer base material. The antibacterial agent supported on the titanium-based ceramic is 0.1%. It is mixed at a ratio of 5% to 1.5% by weight.

According to the grip for a golf club according to the present invention having the above-described structure, the material is formed by mixing the antibacterial agent with the material. Is suppressed, and extremely sanitary and improved durability can be achieved. As an antibacterial agent, silver that is safe and has an excellent antibacterial effect is supported on titanium oxide in the form of ultrafine particles, so that even a small amount of silver has a large surface area. Since the amount of slag is small, it hardly affects the properties of the grip material, and because of its good dispersibility in the raw materials, the antibacterial function can be sufficiently spread over the surface. The grip conforms to the standard conditions even when formed using the grip material described above.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The club 1 shown in the embodiment also has the same basic configuration as that of the conventional club. As shown in FIG. 1, a wood head (not shown) is attached to one end of a shaft 2 manufactured according to a predetermined standard. And an iron head, and a grip 3 on the other end. The club 1 is characterized in that a grip 3 whose basic configuration is equivalent to the grip of a conventional club is formed by a grip material in which an antibacterial agent is mixed into the grip material, as described in detail later. doing. The grip 3 has a substantially bottomed cylindrical shape as a whole with an opening 3a into which the shaft 2 is fitted at one end. Although not shown, a small hole for venting air is formed in the other end of the grip 3.

The grip 3 is securely fixed and attached on a base such as an adhesive tape wound in advance on the shaft 2. That is, the grip 3 is configured by, for example, helically winding a grip material formed in a tape shape on an adhesive tape. In addition, as the tape-shaped grip material, for example, a material whose mechanical strength is improved by enclosing a wire is used.

The grip 3 is formed by, for example, press-fitting a grip material integrally formed in a substantially cap shape by a compression molding method, an injection molding method or the like into a shaft around which an adhesive tape is wound. Further, the grip 3 is formed by, for example, outsert molding a grip material into a predetermined shape at one end of a shaft that has been subjected to a base treatment.

The grip 3 includes, for example, a step of winding a grip material to which an additive and an antibacterial agent described below are added while rolling with a roll around a core rod loaded in a cavity of a molding die, and It is molded through the process of tightening, compressing and molding. In addition, the grip 3 is loaded with a rubber sheet material mixed with a non-slip cord made of, for example, a cotton material into the cavity of the molding die, and the die is clamped to apply a compression to the non-slip cord. A mixed sheet layer is formed on the surface. In such a grip 3, an antibacterial agent is mixed with the cotton material and / or the base rubber sheet material.

As the grip material, materials having various characteristics required for the grip 3, such as water repellency, abrasion resistance, flexibility, air permeability, and shock absorption, are used. As the grip material, for example, a mixed material of natural rubber and various synthetic rubber resins such as EPOM and SBM or various synthetic resin materials which are generally used in the past are used, and an antibacterial agent is mixed with this material. The grip material is configured.

As the antibacterial agent, a silver-based antibacterial agent obtained by supporting ultrafine silver having a particle size of nano-order on titanium anatase oxide is used. Silver-based antibacterial agents do not cause silver volatilization or evaporation even by heat during molding of the gripping material, and do not cause a change in components under normal use conditions at room temperature. It is kept in an extremely stable state.

Antibacterial agents have recently been used in various products provided as so-called antibacterial goods, and are composed of a single metal of silver, copper, and zinc or a mixture thereof, which is safe and has an antibacterial action. In particular, silver is mainly used because of its higher safety and antibacterial properties. Although the antibacterial effect of metal (silver) has not been fully elucidated, it is said that active oxygen generated by the catalytic action of silver damages cell membranes of bacteria, and that silver taken into bacteria cells It is explained by the theory that ions bind to the enzyme (protein) and inhibit metabolic function.

The silver-based antibacterial agent has silver, which is the main antibacterial agent, supported on pores or a crystal lattice of a carrier of an inorganic oxide such as titanium oxide, silica gel, zeolite, water-soluble glass or calcium phosphate. The carrier does not have an antibacterial effect by itself, but has an effect of uniformly dispersing silver in the resin material. Since the antimicrobial agent is mixed uniformly with the resin material and is relatively small, it hardly affects the properties of the product. However, since products are generally made based on the properties of the material alone, it is preferred that the amount of additives that may have any effect on this property be smaller.

Accordingly, the club 1 forms the grip 3 by mixing a silver-based antibacterial agent having a large antibacterial action into the grip material, but retains the characteristics of the grip material sufficiently and uses a smaller amount of the antibacterial agent to form the grip 3. In order to exhibit an antibacterial effect, a silver-based antibacterial agent having the above-mentioned particle size in which nanoparticulate ultrafine silver is supported on anatase titanium oxide is used. Such a silver-based antibacterial agent secures a larger surface area of silver, so that the antibacterial action of silver is more effectively exhibited even in a small amount.

[0025]

【Example】

 As an example, the grip 3 was formed using "Gintech", a trade name of silver antibacterial agent manufactured by Daido Steel Co., Ltd. as a silver-based antibacterial agent. The specifications of "GinTech" are powder standard, 0.2 micron to 0.02 micron in size, ceramic oxide based on titanium oxide and silica gel, silver content 1% to 50%. "Gin Tech" is a master batch standard product, in which PE, PP, PS, PVC, ABS, and PET are used for the polymer, and the amount of addition is 5.2%.

In this “GinTech”, a grip 3 was molded by the above-described method by mixing the rubber material obtained by mixing natural rubber and EPOM at a weight ratio of about 1%. Escherichia coli 300,000 / ml was dropped on the grip 3 and the concentration after 24 hours was measured. As a result, it was 10% by weight. On the other hand, a conventional grip molded with a rubber resin not mixed with "GinTech" had a measurement result under the same conditions of up to 1.2 million wt%.

Therefore, the club 1 is extremely hygienic because it exerts a very remarkable antibacterial action on the grip 3 for suppressing the growth of mold and germs, and the durability is greatly improved. When the weight ratio of the antibacterial agent to the grip material is less than 0.5%, the antibacterial effect is slightly deteriorated, and it is not necessary to mix the antibacterial agent at a weight ratio exceeding 1.5%. Is preferred. The club 1 includes the grip 3 formed of the grip material described above, but does not deviate from required standard conditions.

[Effect of the invention]

 As described in detail above, according to the grip for a golf club according to the present invention, the grip is formed from a grip material in which an antibacterial agent in which silver is supported on titanium oxide in a state of ultrafine particles is mixed with the grip material. Therefore, even in a relatively small amount that does not affect the properties, it is dispersed in a good condition in the grip material and the antibacterial function is fully exhibited, and the generation and propagation of mold and bacteria are suppressed. It is extremely hygienic and has improved durability.

Further, according to the golf club grip of the present invention, since the antibacterial agent is mixed in the sheet layer on the surface of which the non-slip cord is mixed, the generation and propagation of mold and germs are suppressed. It is extremely sanitary and the grip durability is improved.
