Abstract

A combined structure of a golf club head, comprising a club head body and at least one light cover plate. A striking panel is formed on the front of the club head body, and a recessed portion is formed on the top thereof. The recessed portion has a bonding surface. The bonding surface is regularly provided with a plurality of escape holes and a plurality of elastic deformation ribs. Thus, when the light cover plate is combined with the recessed portion of the club head body, the light cover plate and the escape holes effectively reduce the weight of the upper half of the golf club head and increase the elastic deformation capability of the striking panel to bend backward. The elastic deformation rib is used to ensure the structural strength of the recessed portion.

Description

Combination structure of golf club head

technical field

The present invention relates to a combined structure of a golf club head, in particular to a club head body forming a recessed part in the shaft part, the recessed part is provided with several escape holes and several elastically deformable ribs for adjusting the overall center of gravity and gain Combination structure of golf club head for hitting performance.

Background technique

The combined structure of the known golf club head, such as the invention patent of Japanese Patent Application Laid-Open No. 2003-111874 "golf club head", provides an opening at the top (crown portion) of a club head body, and is combined with the inside and outside of the opening respectively. A flat material of suitable strength, such as a pre-formed carbon fiber sheet. The carbon fiber sheet has a specific gravity of about 1.8 grams per cubic centimeter. The club head body is usually made of metal or alloy such as titanium, and the specific gravity of titanium is about 4.5 grams per cubic centimeter. Therefore, by virtue of the carbon fiber plate replacing part of the metal material of the center of the club head body, this combined structure is conducive to relatively downward and backward adjustment of the overall center of gravity of the club head, thereby increasing the moment of inertia and hitting performance of the club head . At the same time, since the top of the club head body forms the opening, a striking panel of the club head body will have an elastic deformation margin for backward deflection when striking.

Another known combined structure of golf club heads, such as the invention patent of U.S. Patent No. 6,623,378 "Golf club head and its manufacturing method (Method for Manufacturing and Golf Club Head)", it is also opened on the top of a club head body (crown Portlon) An opening is further formed to extend toward the toe and the heel, and the opening is correspondingly combined with a carbon fiber plate. Therefore, by replacing the metal material of the top, toe and heel of the club head body with the carbon fiber plate, the combined structure will have a greater margin for adjusting the center of gravity. At the same time, since the top, toe and heel of the club head body form the opening, a striking panel of the club head body has a larger elastic deformation margin for backward flexure.

Although the above-mentioned golf club head structures are all beneficial to increase the elastic deformation capacity of the striking panel, because the opening of the top of the club head body is completely hollowed out and lacks a supporting structure, the structural strength of the top is generally relatively low. In particular, when the hitting panel is subjected to an excessive hitting stress in an instant and produces an excessive amount of backward deflection, it is easy to compress the carbon fiber plate and cause the carbon fiber plate to break. On the other hand, even if the hitting panel is not subjected to excessive impact stress, after the golf club head is used for hitting the ball for a long time, the top of the club head body will still be elastically deformed repeatedly, which will affect the relationship between the opening and the hitting panel. Bond strength and reliability. Therefore, it is still necessary to further improve the combined structure of the golf club head.

In view of this, the present invention improves the above-mentioned shortcomings, and proposes a combined structure of a golf club head.

Detailed ways

In order to allow the above-mentioned technical solutions, features, and advantages of the present invention to be more clearly understood, the preferred embodiments of the present invention will be specifically cited below, together with the accompanying drawings, as follows:

Referring to FIGS. 1 and 2 , the combined structure of the golf club head according to the first embodiment of the present invention includes a club head body 1 and at least one lightweight cover 2 . The club head body 1 is made of metal and alloy materials with high specific gravity, such as carbon steel, stainless steel, iron-manganese-aluminum alloy and titanium alloy, etc., and its specific gravity is usually greater than 3.5 grams/cubic centimeter. The club head body 1 is made by combining multiple pieces, and it is properly provided with a striking panel 11 , a sleeve neck 12 and at least one recessed portion 13 . The hitting panel 11 is arranged on the front of the club head body 1 for hitting golf balls. The sleeve neck 12 is formed on one side of the hitting panel 11 for coupling with a golf club body. The concave portion 13 is at least opened on the crown of the club head body 1 , and preferably extends toward the toe and the heel of the club head body 1 . The concave portion 13 forms a bonding surface 130 for bonding the lightweight cover plate 2 . The bonding surface 130 further forms a plurality of escape holes 131 and a plurality of elastic deformation ribs 132 in a regular and staggered manner. The escape hole 131 is preferably polygonal, such as hexagonal. The elastic deformation auxiliary strips 132 are formed between the escape holes 131 , and because the elastic deformation ribs 132 have appropriate width and thickness, they have appropriate elastic deformation capabilities. Furthermore, the lightweight cover plate 2 is made of lightweight materials with a specific gravity less than 2.7 grams/cubic centimeter, which is preferably selected from carbon fiber (1.8 grams/cubic centimeter), rubber (0.9 to 1.2 grams/cubic centimeter), Plastic (0.9 to 1.4, such as polyetherimide, polyetherimide, PEI), magnesium alloy (1.74 g/cm3) and aluminum alloy (2.7 g/cm3). The shape of the lightweight cover plate 2 corresponds to the shape of the recessed portion 13 of the head body 1 .

Please refer to FIGS. 1 and 2 again. During assembly, the lightweight cover plate 2 can be bonded to the bonding surface of the recessed portion 13 of the club head body 1 with an appropriate adhesive such as epoxy resin (epoxy) or elastic filler. 130 on. The elastic filler can be selected from thermoplastic elastomer material, rubber or polymer polymer material, such as PU elastic filler (polyurethane, PUfiller) and the like. After assembly, since there is a large difference in specific gravity between the materials of the lightweight cover plate 2 and the club head body 1, and the joint surface 130 of the recessed portion 13 of the club head body 1 is provided with the material escape hole 131, so the The light weight cover plate 2 and the escape hole 131 can gain and adjust the center of gravity margin, so as to reduce the weight of the upper half of the golf club head, which is conducive to greatly adjusting the overall center of gravity of the golf club head downwards and backwards, and Relatively increase the moment of inertia length of the golf club head. Furthermore, since the recessed portion 13 of the club head body 1 extends from the top to the heel and toe, a deflection buffer space can be formed between the heel, top and toe of the club head body 1, thereby further The elastic deformation ability of the hitting panel 11 of the club head body 1 to flex backward is improved. At the same time, the concave portion 13 of the club head body 1 is provided with the elastic deformation rib 132 on the joint surface 130, so that the structure of the concave portion 13 can be further strengthened and ensured without excessively increasing the weight of the top or affecting the elastic deformation ability. strength.

On the other hand, when the lightweight cover 2 made of rubber is selected, the lightweight cover 2 will have a shock-absorbing effect. In this way, when the hitting panel 2 is flexed and deformed backward under the stress of hitting the ball, the lightweight cover plate 2 can properly absorb the aftershock of the ball being hit by the elastically deformed ribs 132 of the concave portion 13 at the same time, thereby improving the grip of the club. Maintain comfort and ensure the structural reliability of the elastically deformable ribs 132 . If the present invention uses elastic fillers to bond the joint surface 130 of the lightweight cover plate 2 and the recessed portion 13 , the elastic fillers also have shock-absorbing properties, and can also achieve the above-mentioned shock-absorbing effect.

Please refer to FIGS. 3 to 5 , which disclose the combined structure of the golf club head according to the second to fourth embodiments of the present invention. Compared with the first embodiment, the second to fourth embodiments choose to form several material escape holes 131 on the joint surface 130 of the recessed portion 13 , and the material escape holes 131 are geometric shapes such as circle, quadrangle and triangle. The elastic deformation ribs 132 are formed between the escape holes 131 . Thereby, the escape holes 131 and the elastically deformable ribs 132 can also be used to reduce the weight of the top, adjust the overall center of gravity, increase the ability of deflection and deformation, strengthen the structural strength, increase the shock absorption effect and improve the grip comfort of the club. Furthermore, in addition to forming regular geometric shapes, the bonding surface 130 of the present invention can also optionally form material escape holes 131 with different diameters, or material escape holes 131 with irregular shapes.

Please refer to FIGS. 6 to 8 , which disclose the combined structure of the golf club head according to the fifth to seventh embodiments of the present invention. Compared with the first embodiment, the fifth to seventh embodiments choose to form several material escape holes 131 by the joint surface 130 of the recessed part 13, and the material escape holes 131 are geometrically shaped like strips, pyramids and waves. shape. In the fifth embodiment, the strip-shaped escape hole 131 extends from the front side of the club head body 1 (near the striking panel 11 ) to the back side, and forms a strip-shaped elastically deformable rib 132 . In the sixth implementation, the pyramid-shaped fleece bars 131 extend alternately from the front to the back of the club head body 1 , or extend from the back to the front, and form elongated elastically deformable ribs 132 . In the seventh implementation, the wavy escape hole 131 is also formed to extend from the front to the back of the club head body 1 , and forms a wavy elastically deformable rib 132 . In this way, when the hitting panel 2 is deflected and deformed backward under the stress of hitting the ball, the elastically deformable ribs 132 can not only form a proper amount of elastic deformation, but also form an effective structural support effect by connecting the back surface. Therefore, the escape hole 131 and the elastically deformable rib 132 can also be used to reduce the weight of the top, adjust the overall center of gravity, increase the deflection and deformation capacity, strengthen the structural strength, increase the shock absorption effect and improve the grip comfort of the club.

As mentioned above, compared with the combination structure of the known golf club head, which is easy to cause the carbon fiber plate to break or fall off due to the opening formed on the top of the club head body, the present invention forms the depression on the top of the club head body 1 part 13, and form the material escape hole 131 and the elastic deformation rib 132 on the joint surface of the recessed part 13, which can indeed reduce the weight of the top, adjust the overall center of gravity, increase the deflection deformation capacity, strengthen the structural strength, increase the shock absorption effect and enhance the The grip of the club is comfortable, which in turn increases the added value of the club head.

But the above-mentioned ones are only specific embodiments of the present invention, and are not used to limit the scope of the present invention. Therefore, all equal changes and changes made according to the shape, structure, characteristics and spirit described in the scope of the patent application of the present invention Modifications should be included in the patent application scope of the present invention.
