Description

  The present invention relates to a golf club head capable of appropriately adjusting the feel at impact and the resilience at the time of hitting according to the situation on the day of play.

  In recent years, golf club heads in which a resin material such as urethane is combined on the face surface are increasing. In such a golf club head, by appropriately adjusting the hardness of the resin material, it becomes possible to appropriately adjust the resilience when the ball is hit and the contact time between the face surface and the ball. It is said that the controllability to the ball is increased and the directionality of the hit ball is stabilized.

  Among the conventional techniques that employ a golf club head in which a resin material is composited as described above, there are golf club heads that have been devised in a head configuration so as to generate a large hitting sound while maintaining a soft hitting feeling. (For example, refer to Patent Document 1). In this conventional technology, it is said that a comfortable and loud hitting sound can be generated while maintaining a soft hitting feeling, so that the directionality and the feeling of distance are easily controlled, and a stable stroke and putting result can be obtained. .

  However, the feel at impact and resilience optimal for the player differ depending on the situation on the day of play. For example, since the flying distance of the ball varies depending on the humidity and wind direction on the day of play, there is no guarantee that a stable shot can be obtained even if the same shot feel is maintained. Furthermore, with respect to putting on the green, the feel at impact required for the player differs depending on the grass pruning state on the day of play and the position of the hole. For this reason, it can not be said that the optimal and comfortable hitting feeling and hitting sound on a certain day are optimal on different days. For this reason, in order to obtain a truly optimal shot feeling, it is necessary to prepare a plurality of types of clubs for the same type of golf clubs in advance and play on the day of the game. Not right.

  An object of the present invention is to provide a golf club head capable of appropriately adjusting the hitting feeling and the resilience at the time of hitting according to the situation on the day of play.

  The golf club head according to the present invention is attached to the end of the golf club (wood type, iron type, utility type, putter type) opposite to the grip. This golf club head includes a club head main body and a face plate. The club head main body has a concave portion at a location where a ball is hit on the face surface (a hitting area). The face plate is configured to fit snugly into the recess of the club head main body, and is configured to be detachable from the club head main body. Examples of the configuration for making the face plate detachable with respect to the club head main body include a configuration using magnetic force and a configuration using the elastic force of a member to be fitted.

  In this configuration, the face plate can be easily removed from the club head body, and other face plates can be easily attached. Select the face plate that provides the best shot feel according to the situation on the day of play. It becomes possible to do.

  Further, it is preferable to further include a detaching mechanism configured to apply a force in a direction of pushing the face plate from the recess of the club head main body to the face plate. An example of this mechanism includes a configuration using a push magnet catch, but is not limited thereto. In this configuration, since the face plate can be easily removed even when it is fitted in the recess, the face plate can be easily replaced. As a result, it is possible to obtain an optimal hit feeling with a simple operation. In addition, even if the face plate is fitted into the recess, the face plate replacement operation is not hindered, so that the adhesion between the face plate and the club head can be improved.

  Further, in the above golf club head, the face plate is made of tempered glass, and a glass layer disposed at a position in contact with the ball at the time of hitting a ball, and a resin layer configured to hold the glass layer, It is preferable to provide a plurality of types of face plates having different resin layer hardnesses. By adopting such a configuration, it is possible to easily obtain a plurality of types of elasticity by exchanging the face plate, so that an optimal shot feeling according to the golf course of the day and the player's own condition. Can be easily obtained.

  According to the present invention, it is possible to appropriately adjust the feel at impact and the resilience at the time of hitting according to the situation on the day of play.

  FIG. 1 shows a schematic configuration of a putter 10 according to an embodiment of the present invention. In this embodiment, the putter 10 is adopted as an example of the golf club, but the present invention can be applied to golf clubs (wood type, iron type, utility type, etc.) other than the putter type.

  As shown in FIG. 1, the putter 10 has a grip 12 held by a player on one end side of a shaft 14, and a club head 16 is attached to the other end side of the shaft 14. The club head 16 includes a face plate 22 arranged at a location where a ball is hit on the face surface, and a club head main body 20 configured to hold the face plate 22 in a detachable state. Since the present invention is characterized by a club head in a golf club, the configuration of the club head 16 will be described below with reference to the drawings.

  As shown in FIGS. 2 (A) and 2 (B), the club head main body 20 has a recess 24 at a location where a ball is hit on the face surface. The face plate 22 has a shape and a thickness so as to fit into the recess 24 exactly. While the recess 24 is provided with a magnet 26 for holding the face plate 22 by magnetic force, a magnet (not shown) is provided on the contact surface of the face plate 22 with the recess 24 at a position corresponding to the magnet 26. It has been. When the club head main body 20 is made of a metal member, the magnet on the club head main body 20 side can be omitted, but by providing a magnet on the club head main body 20 side, the club head main body 20 can be omitted. Even when 20 is made of a material such as carbon or wood, a stable magnetic force adsorption effect can be obtained. Usually, as shown in FIG. 2A, the face plate 22 is stably attached to the club head main body 20 by a magnetic force. Then, by applying a force against the magnetic force, the face plate 22 is removed from the club head main body 20 as shown in FIG.

  As shown in FIG. 3, the face plate 22 includes a glass layer 222 made of tempered glass and a resin layer 224 made of a resin material. In this embodiment, the glass layer 222 is made of tempered glass having a thickness of about 1.0 mm, which is painted white to improve the design and has a satin finish on the surface. The glass layer 222 is attached to the resin layer 224 via an adhesive or the like. Two magnets (not shown) are embedded in the resin layer 224.

  Further, the putter 10 is provided with a face plate 220 that is used in place of the face plate 22. The basic configuration of the face plate 220 is the same as that of the face plate 22, and, like the face plate 22, has a shape and thickness that fits into the recess 24 of the club head body 20. The face plate 220 includes the same glass layer 222 as the face plate 22 and a resin layer 226 having a hardness different from that of the resin layer 224 of the face plate 22. By configuring the resin layer 226 to be harder (or softer) than the resin layer 224, a different shot feel can be obtained by appropriately replacing the face plate 22 and the face plate 220. For example, by selecting a face plate that matches the green state of the day and the player's condition, it is possible to obtain an optimal shot feeling on that day without preparing a plurality of putters. Here, for convenience of explanation, an example of exchanging the two face plates 22 and 220 has been described, but it is preferable to use three or more face plates having resin layers having different hardnesses. As the number of types of faceplates increases, the feel at impact can be adjusted in multiple steps. On the other hand, since the faceplate itself is excellent in portability, there is no burden on the player when carrying a large number of faceplates.

  Here, the manufacturing process of the glass layer 222 is demonstrated using FIG. First, the sheet-like raw glass used as the glass layer 222 is subjected to a blasting process for forming a satin finish on one side (S1). In this embodiment, the blasting process is performed so that a satin pattern having an average depth of 2 to 10 μm is obtained. The tempered glass is subjected to a chemical strengthening process (S2). In this embodiment, a chemical strengthening treatment is performed on a glass base material made of aluminosilicate glass, for example, in a potassium nitrate molten salt at about 350 to 450 ° C. The glass subjected to the chemical strengthening treatment is washed (S3).

  The cleaned glass is subjected to a resist treatment for covering the surface with an acid resistant resist (S4). The glass having a resist layer formed on the front surface and the back surface is then subjected to a pre-bake process (S5), an exposure patterning process (S6), and a post-bake process (S7) in sequence, thereby forming a resist layer having a desired pattern on the surface. The At this time, the resist pattern is configured such that the resist is not disposed at a location corresponding to the contour of the shape of the glass layer 222. In this state, by bringing the glass into contact with an etching solution containing hydrofluoric acid or the like, grooves for dividing the glass into a plurality of glass pieces having a desired shape are dug. At this time, the etching process is temporarily stopped before the grooves dug from the main surfaces on both sides of the glass penetrate.

  Then, the lamination process which sticks an acid-resistant laminate to the surface on the opposite side to the surface in which a satin pattern is formed is given (S9). By sticking the laminate in this way, the divided pieces of glass are prevented from being dispersed. Furthermore, after that, it becomes possible to proceed with the etching process only from the opposite side of the laminate application surface, and the groove is prevented from penetrating at the center in the thickness direction. Is prevented. Thereafter, the portion where the resist is not applied is further dug with an etching solution, whereby the sheet-like glass base material is divided into a plurality of glass pieces (S10). After being divided into a plurality of glass pieces, a process (S11) for peeling the laminate applied to the surface and a process (S12) for peeling the resist layer with an alkaline peeling solution are performed. Thereafter, each glass piece is inspected (S13), and only non-defective products are transferred to subsequent steps.

  The glass layer 222 manufactured in this way is disposed in a hitting area on the face surface of the club head 16. Since the glass layer 222 is composed of chemically strengthened glass, the glass layer 222 is not broken by an impact at the time of hitting. Moreover, since it is comprised so that the surface may become a satin finish, it is hard to generate | occur | produce a slip at the time of contact with a ball | bowl. Further, the use of the glass material improves the design of the club head 16 face.

  The glass layer 222 is attached to a resin layer such as the resin layer 224 or the resin layer 226 via an adhesive or the like. The resin layer 224 and the resin layer 226 are made of a resin such as U-PE (ultra high molecular weight polyethylene) resin, polyurethane, or polyethylene terephthalate. In particular, since polyurethane is preferably used, polyurethane is used as the resin layer 224 in this embodiment. The resin layer 224 and the resin layer 226 (including three or more resin layers when three or more face plates are used; the same applies hereinafter) are adjusted so that the rubber hardness is different from each other. A magnet configured to be attracted to the magnet 26 is embedded in the resin layer 224 and the resin layer 226. Therefore, the face plate 22 and the face plate 220 are stably fitted into the recess 24 of the club head body 20.

  The club head body 20 is provided with a push magnet catch 28 for the convenience of removing the face plate 22 and the face plate 220. The push magnet catch 28 includes a mechanism that applies a force that pushes the face plate 22 or the face plate 220 from the recess 24 against the magnetic force to the face plate 22 or the face plate 220 by a simple operation from the player. It only needs to be, and it is not limited to detailed specifications. In this embodiment, a commercially available one with a spring built-in type one-push removal function is adopted, but the present invention is not particularly limited thereto.

  As shown in FIGS. 5 and 6, the player can easily push out the face plate 22 or the face plate 220 by operating the push magnet catch 28 to push out the face plate 22 or the face plate 220. In addition, after the face plate 22 or the face plate 220 is removed, an optimum shot feeling can be easily obtained by fitting the face plate having the resin layer having the optimum hardness into the recess 24. When the mechanism using the push magnet catch is not used, the face plates 22 and 220 are removed by inserting a finger or a thin member into the gap between the recess 24 and the face plates 22 and 220. In this case, it is preferable to take measures such as forming the concave portion 24 slightly larger than the face plates 22 and 220 or forming a notch portion into which a finger or a thin member can be inserted for the convenience of removal.

  Further, as shown in FIG. 7, the face plate 22 receives an impact when the ball 30 is struck, but since a force is applied from the ball 30 to push the face plate 22 into the recess 24, the face plate 22 is struck when the ball is hit. 22 does not come off the club head body 20.

  As described above, by selecting the face plate to be attached to the club head main body 20 in the green state of the day before the competition, it becomes possible to easily realize the best club head for the day. For this reason, the player can select an optimal hit feeling from a plurality of types of hit feelings and prepare for playing without preparing a plurality of putters. In addition, since the speed of the green of the day is usually measured with a measuring instrument such as a stump meter, an optimum face plate can be selected with reference to the measured value. Further, an optimal face plate may be selected in accordance with the lawn state, wind direction, humidity, and other information experienced by the player during practice. As a result, the player can run the ball at a predetermined speed regardless of the green state of the day, and can perform stable putting.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
