Description

  The present invention relates to a golf club head having a decorated hosel portion and a golf club using the same, and more particularly, a golf club head having a hosel portion characterized in that a reflective three-dimensional decorative member is fixed to the surface thereof. And a golf club using the same.

  The portion of the golf club head where the shaft is connected is also called a hosel portion or a neck portion, and a hole portion for connecting the tip of the shaft is generally provided inside the cylindrical shape.

  In this way, the hosel part is a part for adhering and fixing the face part for hitting the ball and the tip of the shaft, and it is usually formed integrally with the same material as the head, but the appearance has been completely decorated conventionally It was not applied and lacked design and decorativeness.

  In order to determine the address state, the hosel part has been processed with a plurality of marked lines on the face side surface of the hosel at an arbitrary angle with respect to the shaft axis direction and at intervals in the circumferential direction. It is disclosed that the marked line is formed by recessing the hosel in a groove shape, projecting in a streak shape, drawing with paint, or applying paint to the inner surface of the groove obtained by recessing ( (See Patent Document 1).

  With respect to ferrules (also called sockets), a metallic color intermediate layer such as a metal foil is interposed between the synthetic resin small diameter pipe portion and the synthetic resin large diameter tube portion in order to enhance the decoration effect of the ferrule and thus the golf club. A decorative socket (see Patent Document 2) configured by fixing a decorative ring that is mounted and integrated to an appropriate position in the axial cross section of the socket tube, or a socket body that is divided in the axial direction is divided. A socket (see Patent Document 3) in which a metal decorative ring is provided between cylinders has been proposed.

Registered Utility Model No. 3006951 Japanese Utility Model Publication No. 55-21710 Registered Utility Model No. 3103748

  However, the hosel described in the above-mentioned Patent Document 1 is only processed in consideration of the practical aspect of determining the address state, and it cannot be said that it has been decorated, and has a gorgeousness and gorgeousness. It was still lacking in design and decoration.

  Similarly, the conventional ferrules and golf clubs described in Patent Documents 2 and 3 have a simple design with a series of ring-shaped patterns. It did not shine brightly, it was not enough to attract people's eyes, its design was low, and its decoration effect was low.

  Further, since the conventional ferrule is divided and the decorative ring is interposed, the strength is weak and the ferrule part and the golf club are easily damaged. In addition, there is a drawback that the molding process is complicated, the manufacturing process is complicated, and the cost is increased.

  In particular, the number of female golfers has been increasing recently, and many stylish products have been provided for golf equipment such as wear and golf accessories, and compared to the fact that there are fun fashions, golf clubs have been pursued only for functionality and lack of decorativeness. It was not something that could be enjoyed and used.

  Therefore, the present invention eliminates the above-mentioned drawbacks of the prior art, and does not damage the golf club by decorating it, is not easily damaged, has a high decorative effect, can be manufactured easily and inexpensively, and emits a brilliant light. Accordingly, it is an object of the present invention to provide a golf club that can be used by being remarkably attracted by human eyes and having a hosel used for the golf club head.

  The present invention as means for solving the above-mentioned problems is a golf club head having a hosel part, characterized in that a reflective three-dimensional decorative member is fixed to the surface of the hosel part.

  Also, in the golf club head having the hosel part, a golf having a hosel part, wherein a concave part is formed in a part of the surface of the hosel part, and the reflective three-dimensional decorative member is fixed to the concave part. Club head.

  Further, in the golf club head including the hosel part, the concave part is provided over a circumference of the hosel part.

  Also, in the golf club head having the hosel part, a golf club having a hosel part characterized in that the width of the concave part in the short direction is 2 mm or more and 5 mm or less and the depth is 0.2 mm or more and 2 mm or less. Head.

  In the golf club head including the hosel part, the reflective three-dimensional decorative member has a width of 0.5 mm or more and 3 mm or less.

  In the golf club head including the hosel part, the reflective three-dimensional decorative member is a transparent resin granular material and / or a metal granular material.

  Moreover, the golf club head provided with the said hosel part WHEREIN: The said transparent resin granular material is a golf club head provided with the hosel part characterized by being colored thinly.

  Further, in the golf club head having the hosel part, the golf club head having a hosel part, wherein the resin of the transparent resin granular material is an acrylic resin.

  Furthermore, it is a golf club characterized by including a golf club head having any one of the above hosel parts.

  According to the present invention as described above, since the reflective three-dimensional decorative member is fixed to the surface of the hosel part, it is possible to easily and inexpensively decorate without lowering the strength and without being damaged. In addition, by radiating brilliant light, it is possible to improve the design and decoration effect, and it is possible to provide a golf club that can be used with enjoyment that attracts the eyes of people.

  In addition, since a concave portion was formed on a part of the surface of the hosel portion, and the reflective three-dimensional decorative member was fixed to the concave portion, the reflective three-dimensional decorative member was hardly peeled off, and the fixing strength could be improved. In addition, the overall weight of the head can be reduced. In addition, the weight of the hosel part has made it possible to lower the center of gravity of the head and to design a wide range of weight distribution, and to increase the degree of design freedom, such as the expansion of the sweet area.

  Moreover, since the said recessed part was provided over the circumference of the hosel part, it was good-looking and it became possible to improve design property more.

  Moreover, since the width of the concave portion in the short direction is 2 mm or more and 5 mm or less and the depth is 0.2 mm or more and 2 mm or less, the reflective three-dimensional decorative member can be fixed easily and reliably.

  Further, since the width of the reflective three-dimensional decoration member is 0.5 mm or more and 3 mm or less, it is possible to improve the design and decoration effect without causing any trouble in golf play.

  In addition, since the reflective three-dimensional decorative member is a transparent resin granular material and / or a metallic granular material, it is possible to further improve the design by emitting more brilliant light.

  Further, since the transparent resin granular material is lightly colored, it is possible to improve the design by giving off more brilliant light.

  Further, since the resin of the transparent resin granular material is an acrylic resin, it is less discolored and can emit more brilliant light over a long period of time.

  In addition, since the golf club has any of the above ferrules, the golf club can have the above-described effects.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In the golf club 10, the grip 3 is provided at the upper end of the shaft 2, the lower end of the shaft 2 is inserted into an insertion hole 19 formed in a hosel portion 41 integrally formed with the head 4, and the ferrule 1 is inserted into the lower end of the shaft 2. The insertion part to the hosel 41 is covered and attached. The hosel portion 41 may be formed separately from the head body 49 and joined to form the head 4. A recess 7 is provided on the surface of the hosel portion 41, and the reflective three-dimensional decorative member 6 is fixed to the recess 7 via an adhesive layer 9. The reflective three-dimensional decorative member 6 serves as a decorative body that decorates the hosel portion 41, and may be used alone or as a single-piece decorative body such as a floral pattern or a continuous pattern.

  The hosel portion 41 is a portion for bonding and fixing the face portion 45 for hitting the ball and the tip of the shaft 2, and the length for favorably bonding the shaft 2 is preferably 10 mm or more and 60 mm or less. A golf club head with a slow head speed, such as a putter, can fix the shaft sufficiently even with a length of about 10 mm. However, in a wood golf club head with a fast head speed like a normal driver, the hosel portion 41 is inserted. The length (depth) L of the hole 19 is 30 mm or more and 60 mm or less, and the intermediate iron golf club head has a length of 20 mm or more and 35 mm or less.

  For this reason, the thickness of the connecting portion 43 between the face portion 45 and the hosel portion 41 is applied with an impact force. Therefore, it is necessary to increase the thickness so as not to lose the impact. Although a length for connecting the shaft 2 is required, the strength is sufficiently thinner than the connecting portion 43 between the face portion 45 and the hosel portion 41. Therefore, the recess 7 is desirably provided at a position 3 mm or more and 20 mm or less below the upper end of the hosel part 41.

  The reflective three-dimensional decorative member 6 can be made of resin particles, particularly transparent resin particles, metal particles, glass, jewels, imitation jewels, etc. having reflectivity and gloss. In addition, a chain formed by connecting them with a resin, a metal-coated resin, or a metal can be used.

  The resin used for the resin granular material is not particularly limited as long as it is a resin having reflectivity and glossiness, but it is possible to use a resin having transparency, or a resin colored lightly. It is preferable because it can emit a brilliant light, and the design and decoration are enhanced. An acrylic resin having high transparency and little discoloration is particularly preferable. Further, a general urethane resin is preferable because it has flexibility, but it is preferable to use a type of urethane resin that does not easily yellow because it turns yellow over a long period of time.

  Examples of the urethane resin include a two-component polyurethane resin, which is a room temperature curable resin in which a main component polyol and a curing agent polyisocyanate are mixed at the time of use. Polyols used include acrylic polyols having a hydroxyl group in the molecule, polyester polyols, polyether polyols, polyurethane polyols, etc., and polyisocyanate prepolymers have many types depending on the starting isocyanate used. In general, aromatic isocyanates are easily yellowed by ultraviolet rays and are not preferred. However, xylylene diisocyanate, isophorone diisocyanate, and hexamethylene diisocyanate are preferred because they are difficult to yellow.

  In addition, since the specific gravity of metal particles is generally heavier than that of resin, depending on the amount of the metal particles, the weight of the club head and the balance of the golf club may be affected. It is preferable to use a small metal such as aluminum or titanium.

  For the same reason, a resin granular material coated with a metal film can be used as the metal granular material. The metal to be the coating is preferably a light metal such as aluminum or titanium. For example, by applying an aluminum coating to a urethane-based elastomer or a titanium coating on an acrylic resin, it can have a metallic luster and can be made shiny.

  As the imitation jewel, rhinestone can be suitably used. This rhinestone is an imitation gem made of glass, and can be made into various colors such as blue, red, green and purple by mixing gold, iron and manganese.

  Of the reflective three-dimensional decorative member 6, a transparent one is preferable because the reflection is further increased by attaching a metal to the back surface.

  The shape of the reflective three-dimensional decorative member 6 is not particularly limited as long as it is received in the recess 7, but the opposite side of the adhesive surface, that is, the surface has a curved surface such as a part of a spherical surface, or is like a diamond cut. By having multiple cut surfaces, it is possible to look beautiful using the reflection of light. The back surface of the reflective three-dimensional decorative member 6, that is, the surface facing the hosel portion 41 may be a flat surface, but the convex curved surface of the facing hosel portion 41, that is, a uniform concave shape corresponding to the bottom surface 71 of the recess 7. It is preferable to have a curved surface. This is because such a configuration facilitates bonding and improves the fixing strength.

  Further, the vertical and horizontal widths of the reflective three-dimensional decorative member 6 are not particularly limited, but in the case of individual granular materials, it is preferably set to about 0.5 mm or more and 3 mm or less. The reason why the width is reduced in this manner is that it is affixed on the circumference of the cylindrical hosel portion 41. If it is too large, especially when the back surface of the reflective three-dimensional decorative member 6 is flat, the adhesive part of the affixed part This is because it is not possible to cope with it, and a large float can be made on the left and right, making it easy to come off. Note that the reflective three-dimensional decorative member 6 is fitted to the concave portion 7 with the vertical or / and horizontal width of the reflective three-dimensional decorative member 6 being substantially the same as the width of the concave portion 7 in the short direction, thereby increasing the fixing strength. It is good as well.

  The concave portion 7 formed on a part of the surface of the hosel portion 41 makes it difficult to peel off the reflective three-dimensional decorative member 6 by fixing the reflective three-dimensional decorative member 6 to the concave portion 7 and improves the fixing strength. It is provided for this purpose. By adopting such a configuration, it is possible to prevent the reflective three-dimensional decorative member 6 from being caught and removed, for example, when the golf club is pulled out from the caddy bag.

  The shape, number, and position of the recess 7 are not particularly limited, and may be provided in a desired shape, number, and location. As a specific example, as shown in FIG. 3A, it is provided over the circumference of the hosel part 41, or as shown in FIG. Alternatively, as shown in FIG. 3C, the hosel portion 41 can be provided long in the vertical direction, or as shown in FIG. 3D, it can be provided in a square shape or a circular shape. As the longitudinal cross-sectional shape, a U-shape or the like can be adopted. Furthermore, these can be combined as appropriate. In particular, when it is provided over the circumference of the hosel part 41, it looks good and is preferable. Further, by forming the bottom surface 71 of the concave portion 7, that is, the surface facing the reflective three-dimensional decoration member 6 so as to be linear when viewed from the side, the reflective three-dimensional decoration member 6 can be attached easily and stably. It is preferable because it is fixed.

  If the width of the concave portion 7 in the short direction is too narrow, it is difficult to apply the reflective three-dimensional decorative member 6, and if the width is too wide, an external portion is formed at the joint between the hosel portion 41 and the reflective three-dimensional decorative member 6. An object is easily caught, which is not preferable. Therefore, it is preferable that the width W in the short direction of the recess 7 is 2 mm or more and 5 mm or less.

  If the concave portion 7 is dug too deeply and the thickness N of the concave portion 7 is 0.8 mm or less, the thin portion may be bent when the tip of the shaft 2 is inserted, which is not preferable. Therefore, the depth D of the recess 7 is preferably in the range of 0.2 mm or more and 2 mm or less.

  Furthermore, the relationship between the depth D of the concave portion 7 and the height of the reflective three-dimensional decorative member 6 is not particularly limited, but if the depth D of the concave portion 7 is too deep compared to the height of the reflective three-dimensional decorative member 6. If the reflective three-dimensional decorative member 6 is difficult to stick, conversely, if it is shallow, the reflective three-dimensional decorative member 6 is likely to hit an external object and easily peels off. Therefore, as shown in FIG. 4B, the depth may be such that the reflective three-dimensional decorative member 6 slightly protrudes, but as shown in FIG. It is preferable that the reflective three-dimensional decorative member 6 is slightly deeper than the height and is completely buried in the recess 7.

  When the golf club head 4 is made by the casting method, when the concave portion 7 of the hosel portion 41 is provided over the circumference, the portion corresponding to the concave portion 7 in the mold becomes narrow and the molten metal flow becomes worse. A part of the part corresponding to the concave part 7 is removed from the mold by using a part without the concave part so as to connect the upper end part of the hosel part 41 and the head body 49 with a normal thickness. A method in which the club head 4 in which the recess 7 is not formed over the circumference is post-processed by machining to form the recess 7 over the circumference is preferable because the yield is high and the manufacturing is easy. Further, when the concave portion 7 is cut by post-processing in this way, it is preferable to further improve the flow of hot water by dropping the corner of the protruding portion forming the concave portion 7 of the mold to make it round. Further, when the iron golf club head 4 is made by forging, forging is performed in advance so as to form a recess in a part of the hosel portion 41 that becomes the recess 7, and the recess 7 having a desired shape is machined based on the forging. It is good also as forming.

  The reflective three-dimensional decorative member 6 is bonded to the hosel part 41 by a method in which an adhesive is applied to the hosel part 41 to provide an adhesive layer 9 and the reflective three-dimensional decorative member 6 is crimped on the adhesive layer 9. , A method in which an adhesive is previously provided on the back surface of the reflective three-dimensional decorative member 6 and the adhesive is melted and bonded by ultrasonic vibration or heating, and when the reflective three-dimensional decorative member 6 is made of resin, an adhesive is used. A method of welding by ultrasonic vibration or heating can be used without using. Furthermore, as shown in FIG. 5, a flexible sheet 8 made of synthetic resin or the like having a shape that can be received in the recess 7 can be used. The flexible sheet 8 is configured by fixing the reflective three-dimensional decorative member 6 on one surface in advance by the above-described method and providing the adhesive layer 9 on the other surface. Adhere to. In this case, since a plurality of reflective three-dimensional decorative members 6 can be used to form a series of patterns such as a floral pattern or a continuous pattern in advance, manufacture of the decorative body is simplified and facilitated. .

  As shown in FIG. 4A, the reflective three-dimensional decorative member 6 may be directly fixed without providing a concave portion on the surface of the hosel portion 41.

  The present invention was implemented with respect to the iron golf club 10. First, the head was made using SUS630 (stainless steel) by the lost wax method of casting. A metal gate is provided on the toe side, and a recess that is a part of the recess 7 is formed in addition to the toe side and the heel side of the hosel portion 41 so that the hot water flow is good in the hosel portion 41. The concave portion 7 was machined so as to have a width of 4 mm and a depth of 1 mm downward from a position 5 mm from the upper end of the hosel portion 41. Since the tool for making a hole is different from the tool for cutting a side surface, it is preferable to provide at least a part of the recess in advance. This is because processing can be performed without exchanging the blade, and processing becomes easy.

  The outer diameter of the hosel was 13.5 mm, the inner diameter of the hosel part was 9.2 mm, and the shaft tip diameter was formed to a diameter of 9.0 mm including paint. The portion that fits inside the hosel 41 at the tip of the shaft 2 was scraped off with a paper file. Next, the ferrule 1 was inserted into an appropriate amount (28 mm) from the front end of the shaft 2, and the front end of the shaft 2 was inserted into the insertion hole 19 of the hosel part 41 to be bonded and fixed. The insertion length of the shaft 2 was 28 mm.

  After the shaft 2 and the head 4 are completely bonded and fixed, an adhesive is applied to the concave portion 7, and a granular material that is cut in multiple faces like a diamond cut of a transparent acrylic resin that is slightly light blue, approximately 2.5 mm in length and width Six of the same size were attached to the recess 7 of the hosel part 41.

  As a result, the golf club can be easily enjoyed and used by making it brilliantly shining without damaging the shaft and golf club, without being damaged, having a high decorative effect, and being easily and inexpensively manufactured. It became.
