Description

  The present invention relates to an improvement of a golf putter, and more particularly to a golf putter excellent in the directionality of a hit ball and the rolling of a ball during putting.

  Conventionally, putter clubs in golf, so-called golf putters, are also abbreviated as putters, and are used to roll a ball into a cup on a green. Generally, a shaft that extends downward from a grip held by a player is used. It has a putter head that has a block shape or bar shape at the tip, and hits the ball with the hitting face (face) of this putter head, thereby rolling (putting) in the target direction on the green It is like that.

  By the way, as a putter head of such a putter, a metallic one such as soft iron or brass has been proposed, but the ball hitting surface is inevitably made of a metal material and hits the ball. Therefore, there is a complaint from the player that it is difficult to adjust the distance to which the ball rolls. For this reason, in recent years, various inserts have been provided on the face which is the hitting surface of the putter head from the viewpoint of feeling of hitting (feeling). It has been adopted a structure that is arranged and can enjoy an effect such as a soft feeling.

  For example, in Japanese Patent Laid-Open No. 8-196668, it is clarified that a face plate made of a material such as an elastomer, a synthetic resin or glass is disposed on the hitting surface of a putter head as a face insert. In Japanese Patent Laid-Open No. 2001-62011, a plurality of grooves are formed on the ball striking surface portion of a metal putter head, and further, a low specific gravity metal, synthetic resin, or rubber is included including the groove processing portion. In addition, a structure in which a ball striking surface is formed by integrally molding is also clarified.

  However, in the face / insert structure of putter heads that have been proposed in the past, a soft feeling or touch can be obtained at the time of putting, but the ball is launched at the time of ball collision at the time of putting. Subtle deviations in the direction are caused, the ball rolls in an unintended direction of the player, the ball is undesirably spun, the ball bounces during putting, it enters a meandering state, There are inherent problems such as poor ball rolling and poor directionality due to the great influence of turf resistance. For this reason, the probability that the ball was cup-in was not fully satisfactory.

JP-A-8-196668 JP 2001-62011 A

  Here, the present invention has been made in the background of such circumstances, and the problem to be solved is that the direction of the hit ball is good and the rolling is good, so that the extension is long. It is an object of the present invention to provide a golf putter head structure capable of launching a ball with good directionality.

  In order to solve such a problem, the present invention is configured such that a fluororesin film is fixed to the face portion of the putter head main body via an elastic adhesive layer, and a ball striking surface is constituted by such a film. The gist of the golf putter is characterized by the above.

  In the golf putter according to the present invention, the elastic adhesive layer is advantageously formed of a rubber adhesive.

  Further, according to a preferred aspect of the present invention, the fluororesin film has a thickness of 0.005 mm to 0.5 mm, and the surface of the fluororesin film that contacts the ball is advantageous. It has a smooth smooth surface.

  Furthermore, in the present invention, only the surface on the fixing side of such a film is used so that such a fluororesin film can be effectively adhered (adhered) to the face part of the putter head main body by the elastic adhesive layer. It is desirable that the surface is modified by hydrochloric acid treatment.

  Therefore, in the golf putter according to the present invention as described above, the face surface is constituted by the fluororesin film, and such a film is fixed to the face portion of the putter head main body by the elastic adhesive layer. From the point where the ball hits with the putter head (main body) through the fluororesin film and the elastic adhesive layer when putting, the impact of the putter when the ball collides Is effectively received by the elastic adhesive layer, and in particular, the impact absorbing action of such an elastic adhesive layer effectively absorbs subtle impacts or fine movements and deformations that occur at the time of hitting the ball, so that a soft touch is achieved. This makes it possible to place with a good sense of distance, improve the directionality of the ball launch direction, and to the head body and shaft To eliminate the Waru discomfort, that hammer out a ball of stroke Street, is to allow.

  Moreover, in such a golf putter according to the present invention, the face surface of the putter head main body that is hit by the ball is made of a fluororesin film. In addition, even if the ball is hit in the stage before the lowest point of the arc of the putter swing, for example, when the ball is subject to backspin, the low friction characteristic of the fluororesin film Therefore, it is possible to effectively suppress or prevent the occurrence of undesired backspin (reverse spin) due to slippage with the ball, thereby causing the ball to rotate freely, No more bouncing on the green turf or being affected by the rolling of the ball due to the resistance of the turf, Te, good direction, also, it is the can to come up with a good ball of rolling.

  Further, in the putter head structure according to the present invention, it is only necessary to fix the fluororesin film to the face surface of the putter head main body with an elastic adhesive layer. In addition, since the change in the weight of the putter head can be suppressed as much as possible, it is possible to make a familiar putter easier to use.

  Hereinafter, the configuration of the present invention will be described more specifically with reference to the drawings.

  First, FIG. 1 shows one form of a head part in a golf putter as a front partial view of the lower part of the putter, where 2 is a metal or carbon fiber reinforced metal that extends vertically in a predetermined length. It is a shaft made of resin (CFRP) or the like, and, as is well known, a grip (not shown) that is gripped by a player is provided at its upper end, while its lower end A known metal head body 4 such as a block shape or a bar shape is integrally attached to the portion. A face surface 8 according to the present invention is formed on the face portion 6 which is the front portion of the head body 4.

  Specifically, as is clear from FIG. 2 showing an enlarged AA cross section in FIG. 1 and FIG. 3 showing an exploded view of the head part of the golf putter of FIG. The fluororesin film 10 having a predetermined thickness is fixed by the elastic adhesive layer 12 over the entire surface, thereby providing a face surface 8 having a structure integrated with the head body 4.

  Here, as the fluororesin film 10 fixed to the face portion 6 of the head body 4, polytetrafluoroethylene, polyvinyl fluoride, polyvinylidene fluoride, polychlorotrifluoroethylene, tetrafluoroethylene-hexa A known film made of a fluororesin such as a fluoropropylene copolymer is appropriately used. In general, a film made of polytetrafluoroethylene is advantageously used here. Moreover, as thickness of such a fluororesin film 10, about 0.005-0.5 mm will generally be employ | adopted. If the thickness of this film becomes too thin, it becomes difficult to handle and causes problems such as tearing of the film. On the other hand, if it is too thick, the elasticity of the lower elastic adhesive layer 12 is effective. However, it is difficult to transmit to the ball, and there is a problem that the significance of disposing the elastic adhesive layer 12 is lowered.

  And since the hitting surface of the ball is constituted by such a fluororesin film 10, the ball is hit by abutting on the fluororesin film 10 at the time of putting. The low friction property of the fluororesin film 10 makes it easier and faster to separate the ball, and in addition, it effectively suppresses or prevents the application of undesired backspin. Will come to roll. For this reason, it is possible to prevent the ball from bouncing or jumping up by the turf, and the adverse effects such as resistance by the turf can be effectively avoided, and the rolling of the ball can be greatly improved. In addition, the accuracy of the direction can be effectively increased.

  In the present invention, in order to further enhance the action and effect of such a fluororesin film 10, it is desirable that the surface of the surface that comes into contact with the ball be a smooth and smooth surface. In this case, the smooth surface is Rz of 0.8 μm or less.

  Thus, according to the present invention, the fluororesin film 10 is bonded to the surface of the face portion 6 of the putter head main body 4 using an adhesive that gives the elastic adhesive layer 12, thereby the elastic adhesive layer 12. In order to effectively bond the fluororesin film 10, the fixing side that is the side facing the face portion 6 of the fluororesin film 10 is used. It is desirable that this surface is modified by hydrochloric acid treatment using concentrated hydrochloric acid and adhered on the modified surface. In addition, such hydrochloric acid treatment is generally heat treatment in order to remove the warp or stress of the film after contacting only one side of the fluororesin film 10 with an aqueous solution of concentrated hydrochloric acid for about 10 minutes. It is preferable that the bonding of the putter head main body 4 to the face portion 6 is performed promptly. This is because the modified surface of such a film is easily deteriorated by ozone in the atmosphere.

  Moreover, as long as the adhesive which forms the elastic adhesive layer 12 which fixes the fluororesin film 10 to the face part 6 of the putter head main body 4 is an adhesive which gives an elastic layer, the fluororesin film 10 can be adhered. As long as any adhesive can be used, in the present invention, in particular, rubber adhesives such as acrylic rubber, CR, NBR, SBR, IIR, natural rubber, Various known rubber adhesives such as recycled rubber are advantageously used. Note that the elastic adhesive layer 12 formed using such a rubber-based adhesive or the like generally has a thickness of about 0.01 to 0.5 mm.

  This is because if the thickness of the elastic adhesive layer 12 is too thin, it is difficult to sufficiently exert the functions and effects of the present invention by utilizing the elastic action. In this case, there is a problem that the amount of repulsive force absorbed is increased.

  Since such an elastic adhesive layer 12 exists between the fluororesin film 10 and the face portion 6 of the putter head main body 4, impact and vibration based on the collision of the ball during putting are effectively prevented. Absorption or relaxation is achieved, which gives a soft touch feeling, good feeling, and a subtle sense of distance.

  In short, a golf putter having a structure in which the fluororesin film 10 is integrally fixed to the face portion 6 of the putter head main body 4 thus obtained through an elastic adhesive layer 12, At the time of putting, the impact caused by the collision with the ball is received by the elastic adhesive layer 12, and the impact and the deformation action caused by the impact are effectively absorbed, and the reaction force is correctly applied to the ball. It will be communicated. Further, even if a putting stroke that causes backspin is performed due to the presence of the fluororesin film 10 constituting the ball striking surface, the putter head main body 4 is caused to slip by sliding between the ball and the fluororesin film 10. It is possible to effectively suppress or prevent the ball from being rotated in the backspin direction. This makes it possible for the ball to bounce when launched, or to meander and roll the ball. It is advantageously avoided that the rolling is deteriorated due to the resistance of the turf, so that the ball can be launched as a ball having a good rolling property and thus extending.

  Note that the present invention is not construed as being limited to the structure shown in the drawing or the specific embodiment described above, and is based on the knowledge of those skilled in the art without departing from the spirit of the present invention. It should be understood that the invention can be implemented in a form added with various changes, modifications, improvements and the like.

  For example, various shapes and structures of the putter head are known, and it goes without saying that the present invention can be applied to any of them.

  In the illustrated specific example, the fluororesin film 10 is fixed to the entire face portion 6 of the putter head body 4 through the elastic adhesive layer 12. It is also possible to partially dispose the elastic adhesive layer 12 and the fluororesin film 10 on a part of the face portion 6 of the putter head body 4, specifically, a portion including a hitting ball portion. is there.

It is a front fragmentary figure in the head part concerning an example of the golf putter according to the present invention. It is AA cross-section enlarged explanatory drawing in FIG. It is a disassembled perspective view which shows the structure of the head part of the putter shown by FIG.
