  • One of known methods for manufacturing a head of such a golf club is such that respective parts of the head that are stamped out from thin sheets of plate materials are formed into a predetermined shape by pressing and bending, and then they are combined together by welding. In that case, respective parts are formed to a substantially uniform thickness due to the manufacturing by pressing.
  • the second prior art publication discloses a method of manufacturing a golf club head with at least a face and a sole thereof being formed from a magnesium group alloy, where the surface of the magnesium group alloy is washed by blast (see paragraph number 0005).
  • the third prior art publication discloses the forming of fine irregularities at least on a face of a head by a sand blast process or the like (see paragraph number 0005).
  • an object of the present invention to provide a golf club in which the position of the center of gravity can be easily adjusted, by freely controlling the thickness of head shells, enabling the large-sizing of a golf club head.
  • a golf club comprising a head formed by combining a plurality of metal shells and a shaft attached to the head, wherein at least a part of said metal shells is formed into a certain thickness by a blast grinding process.
  • a golf club according to the first aspect wherein at least a partial portion of said metal shell is formed into a different thickness than that of the remainder thereof by subjecting at least a part of a certain surface thereof to the blast grinding process.
  • a method for manufacturing a golf club comprising a head formed by combining a plurality of metal shells and a shaft attached to the head, which comprises the step of adjusting a thickness of at least a part of said metal shells by a blast grinding process.
  • any desired position on the shells can be formed to a desired thickness by a blast grinding process.
  • FIG. 1 is a partially cutaway perspective view illustrating an embodiment of the present invention.
  • FIG. 2 is a perspective view illustrating an embodiment of the present invention.
  • FIG. 3 is a partially cutaway front view illustrating an embodiment of the present invention.
  • FIG. 4 is an exploded perspective view illustrating an embodiment of the present invention.
  • FIG. 5 is a rear view showing a face shell of a golf club according to an embodiment of the present invention.
  • FIG. 6 is a bottom view showing a sole shell and a peripheral side shell of a golf club according to an embodiment of the present invention.
  • FIG. 7 is a plan view showing a crown shell of a golf club according to an embodiment of the present invention.
  • a golf club head 1 (hereunder referred to as a head) made of titanium alloy comprises a face portion 2 serving as a surface for striking, a crown 3 on an upper side, a sole portion 4 and a peripheral side surface portion 5 .
  • a shaft 7 provided with a grip (not shown) on an upper end is connected to a hosel 6 .
  • the head 1 is constructed by joining respective edges of a plurality of metallic shells together by welding, which are three metallic shells in the present embodiment, consisting of a face shell 11 corresponding to the face portion 2 , a crown shell 12 corresponding to the crown 3 , a sole shell 13 corresponding to the sole 4 and a peripheral side shell 14 corresponding to the peripheral side surface portion 5 , said sole shell 13 and the peripheral side shell 14 being formed integrally.
  • the face shell 11 , crown shell 12 , sole shell 13 and peripheral side shell 14 are obtained by stamping metal pieces out of thin sheets of titanium alloy or the like, and then bending them by pressing, so that they are assembled into the head 1 by welding the respective edges thereof to one another.
  • the respective shells 11 , 12 , 13 , 14 may be manufactured by hot forging or casting.
  • one half-hosel shell 15 forming one half of the hosel 6 is provided so as to integrally extend from one side of the crown shell 12 .
  • the other half-hosel shell 16 forming the other half of the hosel 6 is integrated with said peripheral side shell 14 .
  • the edges of these half-hosel shells 15 , 16 are joined together integrally with said face shell 11 .
  • a shaft attachment pipe 17 for attaching the shaft 7 is fitted into the hosel 6 formed by said half-hosel shells 15 and 16 .
  • the thickness of the respective shells 11 , 12 , 13 and 14 is adjusted by a blasting method through which the surface of a material is subjected to grinding by blasting abrasive (blasting material) thereto, using compressed air and centrifugal force or the like.
  • the grinding process by blasting method of the invention is such that an abrasive S, comprising metals such as iron, sand carbides and oxides, more specifically GC #80 of Green Carborundum or the like is blasted against the surface of work pieces (i.e., the shells 11 , 12 , 13 , 14 ) put on a turn table T in advance, at high speed and an injection pressure of 0.5 MPa, for example, thereby grinding the surface.
  • the surfaces thus ground are the inside and/or outside surfaces of the respective shells 11 , 12 , 13 and 14 .
  • the face shell 11 may be formed thicker in its center portion in such a manner that the thickness “A” of the center portion of the face shell 11 is formed as thick as 2.6 mm, while the thickness “a” of the ground peripheral portion surrounded by chain line in the drawing as thin as 1.8 mm.
  • the crown shell 12 may be formed thicker in its peripheral portion such that the thickness “B” of the peripheral portion is formed as thick as 1.0 mm, while the thickness “b” of the ground center portion thereof which is surrounded by one-dotted chain line in the drawing is formed as thin as 0.8 mm.
  • the integrated sole shell 13 and peripheral side shell 14 may be formed such that the thickness C of the sole shell 13 may be formed as thick as 1.15 mm, while the thickness “c” of the ground peripheral side shell 14 surrounded by one-dotted chain line in the drawing is as thin as 0.8 mm so that the thickness of the sole shell 13 may be formed thicker.
  • the respective shells 11 , 12 , 13 , 14 are adjusted thus way, they are allowed to undergo a pressing process to be formed into a predetermined shape, where necessary, and then the respective edges are welded while the hosel 6 is formed by mating the aforesaid half shells 15 and 16 each other, so that the attachment pipe 17 is inserted into the hosel 6 to thereby insert the shaft 7 into the attachment pipe 17 .
  • a golf club comprising the head 1 formed by combining a plurality of shells 11 , 12 , 13 and 14 , and the shaft 7 attached thereto, wherein the respective shells 11 to 14 are formed with thinned portions having smaller thickness a, b, c and d by grinding, using blasting shot S, the respective shells 11 , 12 , 14 can be lightened by about 5 g, while the weight thus saved can be freely distributed so that it becomes easier to adjust the position of the center of gravity, enabling the provision of a further large-sized head. Further, As compared to the chemical process, the grinding method is more advantageous in uniformity of shape, costs and long-lasting strength.
  • the thickness of at least a part of said respective shells is adjusted by grinding, using a shot blasting S, whereby the thickness of the material can be uniformly reduced even if the material is a titanium alloy or the like.
  • the blast grinding process allows abrasive S to be blasted against any desired position, any desired portion in the respective shells 11 , 12 , 13 and 14 can be readily formed to any desired thickness.
  • the shape of the head is made more stable, with the resultant better cost performance and strength.
  • the present invention should not be limited to the above embodiment, but various modifications are possible within the scope of the invention.
  • a hollow metal head is described in the embodiment, the invention is applicable to both an iron head and a putter head.
  • the three of the face shell 11 , crown shell 12 , sole shell 13 and peripheral side shell 14 are subjected to the grinding process in the foregoing embodiment, at least one of the four shells may be ground.
  • the parts are subjected to the grinding process in the foregoing embodiment, raw material, materials partially joined by welding or the like and even finished products may undergo the blast grinding of the invention
  • a relatively thick metal sheet may be ground except a part thereof so as to make it serve as a balance weight. As such a balance weight is a built-in weight, there is no likelihood that it drops out.
