  The present invention maximizes the moment of inertia at the same weight and at the same time greatly increases the adjustment of the center of gravity depth, stabilizes the stroke at the time of putting, reduces the distance of the ball at the time of a miss hit, and the blur of the directionality Regarding the putter head.

  Forging, which is a conventional manufacturing method, has been confirmed to be effective in stabilizing the stroke during putting, ball distance at the time of a miss-hit, and maximizing the moment of inertia and adjusting the center-of-gravity depth for the purpose of reducing direction blur. In the processing such as casting and cutting, there are structural limitations and the degree of freedom in design is low.

  Even when the structure of the golf club putter head is hollow, a wall surface is required for any one of the upper surface, the lower surface, and the side surface.

  The present invention has been made to solve such a problem, and by maximizing the moment of inertia at the same weight, and at the same time, greatly increasing the adjustment of the center of gravity depth, stabilizing the stroke at the time of putting, and at the time of mis-hit An object of the present invention is to provide a golf club putter head that can reduce the distance and direction of the ball.

  Using a laser processing machine, wire cut, punching machine, cutting machine, etc., metal and resin plates with different thicknesses are processed to create parts with complicated and precise structures, and a space is provided between the metal parts. A golf club putter head with a laminated structure.

  Considering the weight adjustment and distribution of the center of gravity to the periphery with metal and resin plates of different thicknesses, the structure is laminated so as to create a space, thereby maximizing the moment of inertia and simultaneously adjusting the center of gravity depth significantly. Can be increased.

  Metal and resin parts are symmetrical when viewed from the top when completed.

  Resin parts are used to cover cavities in metal parts for safety and design purposes, but they are not limited to symmetrical shapes when necessary for design.

  Resin parts used for safety and design purposes are fixed with metal parts and can be replaced when damaged or when design changes are required.

  For metal parts arranged for the purpose of fixing resin parts used for safety and design purposes, it is not always necessary to have left-right symmetry when viewed from above when assisting the design purpose of the resin parts.

  The face member is made of metal or resin having a specific gravity of about 1.0 to 3.0 for adjusting the depth of the center of gravity, and the sole bar is made of a material having a specific gravity of 2.0 to 9.0 for adjusting the weight and adjusting the depth of the center of gravity. The face member and the sole bar are arranged in a T-hour mold.

  A structure in which a space is provided between the metal parts from the upper surface of the sole bar and the metal parts are laminated, and the shape of the metal parts can be any shape including resin parts arranged for design purposes.

  The sole bar and the hosel have a structure in which a protruding portion is formed on the sole bar by cutting or welding and the hosel bottom and the protruding portion are joined by a bolt.

  Embodiments of a golf club putter head according to the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is a schematic view of a golf club putter head according to the present invention, and FIG. 2 is a side view.

The face 1 uses an aluminum alloy, but a metal or resin having a specific gravity of about 1.0 to 3.0 may be used for adjusting the weight and adjusting the depth of the center of gravity.
On the back side of the ball striking surface, a screw process for fixing the metal part a4 is performed.

  The metal part a4, metal part b5, metal part c6, metal part d7, metal part e9, sole bar 3 and hosel 2 use stainless steel, but the specific gravity is 2.0 to 9 for adjusting the weight and adjusting the depth of the center of gravity. About 0. 0 metal is sometimes used.

  In joining the sole bar 3 and the hosel 2, a protruding portion is formed by cutting or welding on the upper face 1 contact side of the sole bar 3, and the protruding portion is threaded, and the hosel 2 is fixed with a bolt.

  For joining the sole bar 3 and the metal part a4, the sole bar 3 is threaded and joined with bolts and nuts. In order to increase the bonding strength, an adhesive may be used in combination.

  The face contact side of the metal part a4 is bent in an L shape, and that portion is fixed to the back side of the hitting surface of the face 1 with a bolt, and the face 1 and the sole bar 3 are arranged in a T shape.

  A metal part b5, a metal part c6, a metal part d7, and a metal part e9 are stacked on the metal part a4. A spacer 12 is sandwiched between the metal part a4, the metal part b5, and the metal part c6 to create a space. The spacer 12 is made of resin or metal, and is displayed in a cylindrical shape in FIGS. 1 and 2, but the shape is designed in consideration, and foreign matter enters the space of the metal part a4, metal part b5, and metal part c6. In the case of the purpose of preventing, etc., the cylinder type is changed. The height of the spacer 12 is determined so that the upper surface of the face 1 and the metal part 9 have the same height.

  The bolt a10 is threaded to fix the metal part e9 with the bolt b11. The length of the bolt a10 is the length from the lower surface of the metal part a4 to the upper surface of the metal part d7.

  The metal part d7 is threaded, and the metal part b5, the metal part c6, and the spacer 12 are fixed using the bolt a10 from the lower surface of the metal part a4.

  The resin component 8 is placed on the upper surface of the metal component c6, and the outer periphery is fixed by the metal component 7 from the upper surface by the metal component e9 and the bolt b11. In the case of breakage of the resin part 8, change of design, etc., a fixing method that can be changed is adopted. The bolt b11 is preferably a Sarah bolt.

  1 and 2, only one metal part b5 is displayed between the metal part a4 and the metal part c6, but it is used for design consideration, maximizing the moment of inertia, adjusting the weight, and adjusting the center of gravity depth. If not, there are also cases where multiple sheets are used.

  The metal part a4, the metal part b5, the metal part c6, the metal part d7, and the metal part e9 have a symmetrical shape when viewed from above, but the thicknesses do not have to be the same.

  When the metal part e9 is also viewed from above, a symmetrical shape is preferable, but for the purpose of assisting design consideration of the resin part 8, the symmetrical shape is not concerned.

  There are cases where a plurality of resin parts 8 are used in combination in consideration of design.

  The sole bar 3 has a semicircular cross section in FIGS. 1 and 2, but any shape is applicable.

The measurement data of the center of gravity depth and the moment of inertia of the golf club putter head of this example will be described. Golf club putter head upper surface size 110 mm × 95 mm Weight 357 g Depth of center of gravity 40.1 mm Moment of inertia 8301 gcm ² The effect of the present invention can be confirmed.

  The present invention can be used for various golf club putter heads.
