Abstract
A wood golf club head has a sole plate, a crown, a strike face and a hosel that are all made of metal and are welded together. The sole plate is formed by forging to have different thicknesses at different parts and has a weight formed as a thicker part of the sole plate. Therefore, when the wood golf club head is manufactured, the shape, the size and the position of the weight is precisely set based on the design of the wood golf club head. Then the gravity center of the wood golf club head is accurately determined. Moreover, since the weight is directly formed on the sole plate without any gaps and the shape of the weight is simple and smooth, the wood golf club head performs a clear and pleasing striking sound while it strikes.
Description
- 1. Field of the Invention
- The present invention relates to a golf club head, especially to a wood golf club head.
- 2. Description of the Prior Arts
- Wood golf club heads have special shapes so that the wood golf club heads are difficult to be formed as one piece. Therefore, the wood golf club heads made of metal are usually manufactured as two-pieces, three pieces or four pieces. The pieces are welded to form a wood golf club head with predetermined appearance.
- With reference to
FIG. 4 , a conventional wood golf club head with four pieces comprises asole plate 20, acrown 21, astrike face 22, ahosel 23 and aweight 24. One side edge of thecrown 21 is attached securely to an upper side edge of thesole plate 20. Side edges of thestrike face 22 are respectively attached securely to front side edges of thesole plate 20 and thecrown 21. Thehosel 23 is connected securely to end edges of thesole plate 20, thecrown 21 and thestrike face 22. Theweight 24 is mounted securely on thesole plate 20 to lower and determine the center of gravity of the conventional wood golf club head. Theweight 24 may be welded, screwed or glued on thesole plate 20. When theweight 24 is welded on thesole plate 20, the connection between theweight 24 and thesole plate 20 is firmer so that theweights 24 of most of the conventional wood golf club heads are welded on theirsole plates 20. - To weld the
weight 24 conveniently, theweight 24 is only welded at multiple points on the inner top surface of thesole plate 20 instead of welding at full periphery edge since the periphery edge of theweight 24 has a certain length. Thus, thewelded parts 25 are arranged in intervals around theweight 24. However, the welding in intervals provide worse bond than welding at full periphery. Besides, the material of thewelded parts 25 is softer than the material of theweight 24 and thesole plate 20. When the wood golf club strikes for multiple times, thewelded parts 25 are easily broken so that theweight 24 easily departs from thesole plate 20. - Additionally, with reference to
FIG. 5 , theweight 24 is welded on thesole plate 20, which has a curved inner top surface. Therefore, the bottom surface of theweight 24 does not flush with the inner top surface of thesole plate 20. Agap 26 is consequently formed between theweight 24 and thesole plate 20 so that theweight 24 and thesole plate 20 are not bound smoothly. Furthermore, since the adjacentwelded parts 25 also have a gap formed between them, the conventional wood golf club head cannot perform a clear and pleasing striking sound while it strikes. Thus, the conventional wood golf club head has poor striking sound. - To overcome the shortcomings, the present invention provides a wood golf club head to mitigate or obviate the aforementioned problems.
- The main objective of the present invention is to provide a wood golf club head that improves the forming process of the weight to precisely determine the position of the gravity center of the wood golf club head. The wood golf club head has a sole plate, a crown, a strike face and a hosel that are all made of metal and are welded together. The sole plate is formed by forging to have different thicknesses at different parts and has a weight formed as a thicker part of the sole plate. Therefore, when the wood golf club head is manufactured, the shape, the size and the position of the weight is precisely set based on the design of the wood golf club head. Then the gravity center of the wood golf club head is accurately determined. Moreover, since the weight is directly formed on the sole plate without any gaps and the shape of the weight is simple and smooth, the wood golf club head performs a clear and pleasing striking sound while it strikes.
- Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
-
FIG. 1 is an exploded perspective view of a wood golf club head in accordance with the present invention; -
FIG. 2 is a cross-sectional side view of the sole plate with the weight of the wood golf club head inFIG. 1 ; -
FIG. 3 is a perspective view of the wood golf club head inFIG. 1 ; -
FIG. 4 is an exploded perspective view of a conventional wood golf club head in accordance with the prior art; and -
FIG. 5 is a cross-sectional side view of the sole plate with the weight of the conventional wood golf club head inFIG. 4 . - With reference to
FIG. 1 , a wood golf club head in accordance with the present invention is used for a wood golf club, which may be a drive, a fairway wood, or a hybrid and so on. The wood golf club head in accordance with the present invention comprises asole plate 10, acrown 11, astrike face 12 and ahosel 13. - The
sole plate 10, thecrown 11, thestrike face 12 and thehosel 13 are made of metal, which may be selected from titanium, stainless steel, carbon steel, aluminum alloy and so on. Thesole plate 10, thecrown 11, thestrike face 12 and thehosel 13 may be made of the same metal or may be made of two different metals. - With reference to
FIGS. 1 and 2 , thesole plate 10 is made of a slab of a bar by hot forging to have different thicknesses at different parts. Aweight 101 is formed as a thicker part of thesole plate 10. Other parts of thesole plate 10 may have uniform thicknesses or may have a uniform thickness, which depends on the designed shape of the club head. The location, the shape, and the thickness of theweight 101 are determined according to the position of a gravity center of thesole plate 10. Theweight 101 may be circular, rectangular and so on. In a preferred embodiment, theweight 101 is rectangular. - The
crown 11 is welded on atop edge 102 of thesole plate 10. Thestrike face 12 is welded between afront edge 103 of thesole plate 10 and afront edge 111 of thecrown 11. Thehosel 13 is welded between anend edge 104 of thesole plate 10, anend edge 112 of thecrown 11 and anend edge 121 of thestrike face 12. The wood golf club head as described has further processing steps such as forming multiple grooves on thestrike face 12, performing surface treatment, and so on to accomplish the wood golf club head as shown inFIG. 3 . Then thehosel 13 is connected securely to the shaft to accomplish the wood golf club. - The wood golf club head as described determines the gravity center via the thicknesses of the
weight 101 and the other parts of thesole plate 10. Atoe end 14 is defined on the end away from thehosel 13 while aheel end 15 is defined on the end near thehosel 13. Thestrike face 12 is defined as a left side of the wood golf club head as described while the opposite side is defined as a right side. The height of the gravity center of the wood golf club head as described is altered by adjusting the thickness of theweight 101. The depth of the gravity center of the wood golf club head as described is altered by adjusting the distance between theweight 101 and thestrike face 12, or by adjusting the distance between theweight 101 and thehosel 13. Thus, the gravity center is shifted as desired so that the manufacturer can design a preferred position for the gravity center based on the need of the wood golf club. On the other hand, since theweight 101 is directly formed on thesole plate 10 without any gaps and the shape of theweight 101 is simple and smooth, the wood golf club head as described performs a clear and pleasing striking sound while it strikes. - Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
