Abstract

A golf club head includes a head body and a top cover. The ball head body includes a main body part and an oblique edge part connected with the main body part. The beveled edge portion has an inclined surface extending obliquely downward in a direction away from the main body portion. The top cover includes a cover body portion, a step portion bent and extended outward from the cover body portion and overlapped at the end of the beveled edge portion, and a step portion extending from the step portion in a direction away from the cover body portion and attached In the junction of the inclined surface. The design of the step part makes the joint part that needs to be polished protrude outward from the cover part, so when the joint part is polished, the polishing area and the non-polishing area can be judged through the height difference, so as to avoid damaging the cover part The outer surface (that is, the non-abrasive area) enables the cover body to expose the outer surface of the composite material pattern to the outside to achieve a better visual effect.

Description

Golf club head

The present invention relates to a golf equipment, in particular to a golf club head.

Referring to Figure 1, the body of a general golf club head will form a gluing area that is joined with the top cover. When carbon fiber composite is used as the material of the top cover, the gluing area usually adopts a stepped design, and the stepped design will be in the head body 11. The outer edge of the top cover 12 is concavely folded to form a stepped structure 111, and a flat surface 112 on which the top cover 12 rests is created. In order to ensure that the outer surface of the top cover 12 can be flush with the ball head body 11, the top The part of the cover 12 corresponding to the glued area is locally thickened. In this way, when the top cover 12 is glued on the flat surface 112, the thickened outer surface will protrude from the surface of the ball head body 11. At this time, the top can be made by grinding. The cover 12 is flush with the ball head body 11. However, because the top cover 12 has no obvious area division, it is easy to grind the top cover 12 to an area outside the predetermined range when grinding the top cover 12, resulting in damage to the outer surface that should have a carbon fiber texture, affecting the aesthetics of the golf club head ; In order to ensure the appearance of the golf club head, the surface of the damaged carbon fiber surface is often painted with a paint layer, but this also greatly limits the area of the golf club head that can show the carbon fiber lines, thereby affecting the vision The aesthetic effect.

Therefore, the object of the present invention is to provide a golf club head that is easy to distinguish between the grinding area and the non-grinding area during grinding.

Therefore, the golf club head of the present invention includes a head body and a top cover fixed on the head body. The ball head body includes a main body part surrounding and defining an inner space, and an oblique edge part connecting the main body part and surrounding and defining an opening connecting the inner space. The beveled edge portion has an inclined surface that extends downward and obliquely toward the outside and away from the main body portion. The top cover is fixed on the inclined surface and located in the opening, and is made of composite material. The top cover includes a cover body portion, a step portion bent and extended outward from the cover body portion and overlapped at the end of the beveled edge portion, and a step portion extending from the step portion in a direction away from the cover body portion and attached In the junction of the inclined surface. The bonding portion is ground to have a ground surface flush with the outer surface of the main body portion and located outside the outer surface of the cover body portion.

The effect of the present invention is that the design of the step part makes the joint part that needs to be polished protrude outward than the cover part. Therefore, when the joint part is polished, the polished area and the non-polished area can be judged by the height difference. The grinding surface is avoided under the condition of damaging the outer surface of the cover body, so that the cover body can expose the outer surface of the composite material pattern to the outside to maximize the appearance and visual effect.

Referring to FIGS. 2, 3, and 4, an embodiment of the golf club head of the present invention includes a head body 2 and a top cover 3 fixed on the head body 2. The ball head body 2 includes a main body 21 surrounding and defining an inner space 211, and a beveled edge 22 connected to the main body 21 and surrounding an opening 221 connected to the inner space 211. The inclined edge portion 22 has an inclined surface 222 that extends downward and obliquely toward the outside and away from the main body portion 21. The top cover 3 is fixed on the inclined surface 222 and located in the opening 221, and is made of carbon fiber composite material (Carbon Fiber Reinforced Polymer, CFRP) or carbon fiber thermoplastic composite material (Carbon Fiber Reinforced ThermoPlastic, CFRTP). The thickness is preferably 0.4 mm to 0.8 mm. The top cover 3 includes a cover body portion 31, a step portion 32 bent and extended outward from the cover body portion 31 and overlapped with the end of the beveled edge portion 22, and a step portion 32 facing away from the cover body The portion 31 extends in the direction and is attached to the joining portion 33 of the inclined surface 222. The coupling portion 33 is ground to have a ground surface 331 flush with the outer surface of the main body portion 21 and located outside the outer surface of the cover portion 31.

Through the upwardly bent step portion 32, a height difference is formed between the connecting portion 33 and the cover portion 31, so that when the connecting portion 33 and the main body portion 21 are connected, the area to be polished can be clearly distinguished (That is, the outer surface of the bonding portion 33), and the non-abrasive area (that is, the outer surface of the cover portion 31, which is distinguished by an imaginary line in FIG. 4), so that the cover portion 31 is not damaged. In the case of the outer surface, the polished surface 331 that is smoothly connected to the main body 21 is polished (the portion drawn by the imaginary line in FIG. 3 is the un polished portion of the bonding portion 33). Since the grinding area and the non-grinding area can be accurately distinguished, there is no need to reserve a buffer area. The area of the grinding surface 331 and the outer surface of the cover portion 31 can be designed according to requirements.

Referring to Figures 4 and 5, it should be particularly noted that in actual manufacturing, the polishing surface 331 and the main body 21 partially connected to the polishing surface 331 can be decorated by painting as shown in Figure 5 (for example, in Figure 5). The illustrated coating A) prevents the unsightly polished surface 331 from being exposed, and only exposes the cover body 31 that is undamaged and retains a complete carbon fiber texture (such as a plain weave or a twill weave of 3K weave). 6 and 7, in addition, the grinding surface 331 may be a curved surface connecting the cover portion 31 as shown in FIG. 4, but may also be an annular surface connected end to end as shown in FIG. The shape can be freely selected according to the desired appearance, and the width of the grinding surface can be 3.0mm to 20.0mm as required; of course, the grinding surface 331 can also be decorated and partially connected to the grinding surface 331 through the coating A The main body 21.

In summary, the present invention generates a height difference through the step portion 32 of the top cover 3, thereby distinguishing the grinding area and the non-grinding area, and accordingly the grinding surface 331 can be accurately ground out of the bonding portion 33 and avoiding damage And the outer surface of the cover body portion 31, so that the cover body portion 31 can expose the outer surface of the carbon fiber pattern to the outside to the maximum, so it can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited by this, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
