Abstract

(57) [Problem] To provide a putter head having a high-grade feel and a high commercial value with a soft and stable shot feeling and a beautiful appearance. SOLUTION: A head body 1 is made of metal, and a recess 2 having a constant depth is formed on a face side thereof, leaving a peripheral portion 11, and the recess 2 has a smooth face surface. In addition, a structure is adopted in which a face plate 3 made of a hard synthetic resin having different colors laminated in layers and exhibiting a stone tone or a marble tone is fitted.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a putter head having an appropriate elasticity, capable of performing soft and stable putting, and having a beautiful appearance and excellent commercial value.

[0002]

[Prior art]

 Conventionally, iron club heads and putter heads of golf club heads are generally made of metal. However, metal heads have poor elasticity and cannot provide a soft feel at impact. For this reason, iron club heads in which the face surface is formed of a fiber-reinforced resin layer, and putter heads in which the entire head is formed of a wear-resistant synthetic resin material have been developed.

[0003]

[Problems to be solved by the invention]

 However, in an un-an-club head, a large impact force acts on the face surface when the ball is hit, and even if the face surface is formed of a fiber-reinforced resin layer, it may be damaged or worn away and endure long-term use. There is a problem that can not be.

On the other hand, in the case of a putter head, since the pad is lightly put by stroking the head with a small swing, the impact force with the golf ball is small, so that even if the putter head is formed of a synthetic resin material, cracks and the like are caused by hitting the ball. There is no danger of this occurring, and a soft and stable hit ball can be obtained by effectively exhibiting the elasticity of the synthetic resin.However, in the conventional putter head, since the entire head is formed of synthetic resin, In addition to the possibility that the sole portion that frequently comes into sliding contact may be worn out in a short period of time, there is a problem that the connecting corner portion between the face and the sole is lost when unexpectedly colliding with another object. Further, since it is formed of a single-color synthetic resin, there is a problem that the color is poor and the appearance is inferior, and the value of the product is reduced and the willingness to purchase is reduced.

[0005] The present invention has been made in view of such problems, and the purpose of the present invention is to make it possible to effectively exert a moderate elastic force of a synthetic resin material to enable soft and stable packing. Another object of the present invention is to provide a putter head having a beautiful appearance and excellent commercial value, with little risk of chipping or wear.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the putter head of the present invention forms a recess on the face side of the head body made of aluminum alloy, brass or other metal, leaving a peripheral portion of the head body, and forming the recess. A face plate made of a hard synthetic resin having a smooth face is fitted into the face and fixed with an adhesive.

[0007] The invention according to claim 2 is characterized in that a pattern in which different colors overlap in a layered manner appears on the face surface. It can be obtained by extruding a kneaded hard synthetic resin having a different color, preferably a urea resin.

[0008]

[Action]

 A hard synthetic resin face plate provides a soft feel when hitting, and the face surface has the unique excellent smoothness of synthetic resin, allowing stable putting. Furthermore, the head body is made of metal, and the hard synthetic resin face plate fitted into the recess on the face surface is surrounded by the peripheral edge of the metal head body, so that the sole part is worn or damaged. It can be used for a long time without any danger.

Further, on the face surface of the face plate, different colors appear in layers to give a natural texture of stone-grained or becco-like, so that the appearance of the decorative plate is rich and excellent. The product value is significantly improved.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the present invention will be described with reference to the drawings. 1 is a putter head body made of an aluminum alloy, brass, stainless steel, or other metal material, and its face 1a. On the side, a recess 2 having an appropriate depth (about 5 to 12 mm) is formed toward the rear wall surface of the head main body 1 except for the peripheral portion 11 of the head main body 1. The peripheral wall surface 2a of the recess 2 is provided in parallel with the toe portion 1b of the head main body 1 to the sole portion 1c, the heel portion 1d, and the upper surface portion 1e. The thickness between the inner and outer peripheral surfaces is formed to be about 2 to 3 mm.

Reference numeral 3 denotes a face plate made of a hard synthetic resin such as urea resin, which is fitted in the recess 2, the front surface of which is formed on a smooth surface, and the face surface of the head body 1 is formed by the smooth surface. Is formed. The face plate 3 has the same shape as the recess 2 and is fitted into the recess 2 and fixed with an appropriate adhesive such as an epoxy-based adhesive or a urethane-based adhesive. It is flush with the front end surface of the peripheral wall portion 11. Further, the face plate 3 is formed by vertically stacking hard synthetic resin layers having different color layers 3a, 3b, 3c,... Of green, white, brown, yellow-green, and the like. The patterns of the stacked color layers are exposed on the face to give a natural texture such as stone-grained, becco-like, or marble-like.

For example, the face plate 3 is formed by kneading a single color urea resin into a clay and extruding it into a rod-shaped molding resin having a constant cross-sectional shape by an extruder. A urea resin of a different color from this molding resin is molded together with the molding resin by an extruder, and this process is repeated to produce a rod-shaped molding resin in which a plurality of layers having different colors are formed over the entire length. Then, this molding resin is cut at every depth interval of the recess 2 to obtain a face plate 3 having a smooth surface.

The metal head body 1 is provided with a hole 5 for mounting a putter shaft 4, and a putter is formed by fitting a lower end of the putter shaft 4 into the hole 5.

When the putter thus configured is padded with the face surface of the face plate 3 made of the hard synthetic resin at the time of use, a very smooth and soft feel at impact is obtained due to the moderate elasticity of the hard synthetic resin. Is obtained, and stable putting is possible in combination with the fact that the face surface forms an accurate smooth surface.

[0015]

[Effect of the invention]

 As described above, according to the putter head of the present invention, a concave portion is formed on the face side of the metal head main body, leaving a peripheral portion of the head main body, and the face surface is formed into a smooth surface in the concave portion. The rigid synthetic resin face plate is fitted and fixed with an adhesive, so that the soft synthetic resin face plate can provide a soft and smooth feel at the time of putting and the face surface Because of the excellent smoothness unique to synthetic resins, stable putting can be performed. Furthermore, the head body is made of metal, and the hard synthetic resin face plate fitted in the recess on the face surface is surrounded by the peripheral edge of the metal head body, so that the sole portion that frequently comes into sliding contact with the green surface is used. There is no danger that the sole portion will be worn out because of the structure made of metal material, and furthermore, due to the peripheral edge of metal, the continuous corner between the face and the sole will be inconsistent with other objects. It can be used for a long time without any risk of losing even if it collides with.

[0016] Furthermore, different colors appear in layers on the face surface of the face plate to give a natural texture of stone, becco or marble, so that the appearance is rich in decorativeness and excellent. It gives a high-quality image and significantly enhances the commercial value.
