Description

golf putter head

technical field

The invention belongs to golf equipment components, in particular to a golf putter head.

Background technique

As shown in Figure 1 and Figure 2, the US Patent No. 6,471,600 'Putter Head (Putter Head)' and US Patent No. 6,506,125 'Putter Head (Putter Head)' disclose the club head body 10' comprising a striking panel 11 ', collar 12', top 101', bottom 102', rear mass part 103', middle hole 104' and at least one aiming mark 105'.

The middle hole 104' is formed between the strike plate 11', the top 101', the bottom 102' and the rear mass part 103'.

Aiming marks 105' are formed on the surface of the top 101'.

The overall center of gravity of the putter head falls in the middle hole 104' between the top 101' and the bottom 102'.

Thereby, relative to the front length A' and the side length B' of the hitting panel 11', the center of gravity and the aiming mark 105' will have the same coordinate positions, so that the user can not only accurately aim the golf ball when hitting the ball, but also The actual hitting point of the hitting panel 11 ′ can be formed on the same straight line as the center of gravity, so as to effectively react the hitting stress to the golf ball, thereby reducing hitting errors and improving hitting accuracy.

Even so, the head body 10' of the above-mentioned putter still has the following other problems during actual manufacture and use. The top 101' and the rear mass part 103' of 10' have mass, so the overall center of gravity of the putter head is actually still higher than the height of the hitting point. As a result, when hitting the ball, the hitting point of the hitting panel 11' and the line connecting the center of gravity are not parallel to the ground, but slightly inclined downward, thus affecting the hitting accuracy of the golf ball. Furthermore, since the club head body 10' has the structure of the center hole 104', its manufacturing process is limited to casting. However, during the casting process, casting defects such as shrinkage cavities and slag holes are easily generated on the inner wall of the middle hole 104', which seriously affects the difficulty of subsequent processing and the yield of the finished product of the rod head body 10'. Therefore, it is still necessary to further improve the structure of the above-mentioned golf putter head.

Detailed ways

As shown in FIG. 3 and FIG. 4 , the present invention includes a club head body 10 and a lightweight insert 20 .

The club head body 10 is a putter-type club head made of stainless steel, carbon steel, titanium alloy, copper alloy and other materials. The club head body 10 is provided with a striking panel 11 , a collar 12 , two side mass portions 13 , a connecting portion 14 and a chamber 15 .

The hitting panel 11 is formed on the front of the club head body 10 for hitting a golf ball; the thickness of the hitting panel 11 is less than 2 mm, preferably less than 1 mm, most preferably 0.5 mm.

The collar 12 is formed on one side of the top surface of the rod head body 10 for coupling with the rod body.

The side mass portions 13 are formed on both sides of the club head body 10 , which constitute the weight configuration of the club head body 10 , and are preferably roughly L-shaped.

The connecting part 14 is connected between the two side mass parts 13 so that the present invention has a better moment of inertia. Usually the thickness of the connecting portion 14 is less than 2 mm, preferably less than 1 mm, most preferably 0.5 mm. One end edge of the connecting portion 14 is connected to the bottom of the striking panel 11 .

The chamber 15 is formed by being surrounded by the connection part 14 , the striking panel 11 and the two side mass parts 13 . The end of the chamber 15 is opened backward and can be combined with the lightweight insert 20 in an appropriate manner.

The lightweight insert 20 is made of a lightweight material with a density lower than that of the club head body 10, such as PU (polyurethane), carbon fiber material, epoxy resin (epoxy), rubber, thermoplastic elastomer (thermoplastic elastomer), natural high molecular polymer or Made of synthetic polymers. At least one aiming mark 21 can be formed on the top surface of the lightweight insert 20 in a suitable way. The aiming mark 21 is in the shape of a straight line or an arrow, so as to facilitate the user to aim at the golf ball.

The length A of the front side of the club head body 10 generally remains greater than the length of the side B. As shown in FIG.

The striking panel 11 is disposed between the two side mass portions 13 .

As shown in FIG. 5 and FIG. 6 , the lightweight insert 20 can be combined into the chamber 15 of the club head body 10 by prefabrication, thermocompression molding or injection molding.

As shown in FIG. 5 , the lightweight insert 20 is pre-molded with a suitable mold and then glued to the chamber 15 of the club head body 10 . At the same time, the aiming mark 21 can be formed on the lightweight slug 20 by printing and coloring, or directly on the lightweight slug 20 by mixing the same filler of different colors when molding the lightweight slug 20. The surface is integrally formed with an aiming mark 21 .

As shown in FIG. 6, the chamber 15 of the club head body 10 can cover the template 30, and directly fill or inject appropriate lightweight materials, so that the lightweight insert 20 can be directly combined with the club head body without using adhesives. 10 in the chamber 15. Next, the aiming mark 21 is formed on the top surface of the lightweight block 20 by printing and coloring.

As shown in Figure 3 and Figure 4, by the relative arrangement of the two side mass parts 13 and the lightweight insert 20,

The overall center of gravity of the present invention will fall in the lightweight insert 20 , and make the center of gravity align with the aiming mark 21 , while the center of gravity can also be kept at the same level as the actual hitting point of the striking panel 11 . Therefore, when putting, the user can use the aiming mark 21 to accurately aim the golf ball, and then when hitting the ball, the hitting stress is applied to the golf ball by the actual hitting point of the hitting panel 11 . Therefore, the present invention can indeed reduce hitting errors and improve hitting accuracy, and the structure of the club head body 10 is simple, which is also conducive to the application of various manufacturing processes and improving product yield. For example, precision casting can be used according to requirements or existing manufacturing processes. , casting, machining, die-casting, forging, injection molding, etc.; or assembled into one piece by segmented joints. Furthermore, the thickness of the striking panel 11 is less than 2mm, which is also beneficial to improve the elastic change ability of the striking panel 11.

As shown in FIG. 7 , one end edge of the club head body 10 a connected to the connection portion 14 a between the two side mass portions 13 is connected to the bottom of the beating panel 11 , and the other end thereof extends upward to form a stop wall 141 . The chamber 15 is surrounded by the connecting portion 14a extending upwards to form the stop wall 141, the striking panel 11 and the two side mass portions 13, and the end of the chamber 15 is opened backwards. After 20, the blocking wall 141 formed by the upward extension of the connecting portion 14a further prevents the lightweight insert 20 from leaving the club head body 10a from the rear of the chamber 15, so that the reliability of the combination of the chamber 15 with the lightweight insert 20 can be relatively increased. Spend.

As shown in Fig. 8 and Fig. 9, the connecting part 14b between the club head body 10b connected to the two side mass parts 13 extends backward to form an extension plate 16 with a rear mass part 17 at the end, so that the club head body 10b is in the shape of T-shaped, and the front length A of the club head body 10b is preferably greater than the side length B thereof. At the same time, a T-shaped lightweight insert 20b is appropriately combined with the space above the chamber 15 and the extension plate 16, and at least one aiming mark 21 is formed on the top surface of the lightweight insert 20b. The aiming mark 21 can be in the shape of a straight line, an arrow, a circle, an ellipse or a triangle. Thereby, the club head body 10b and the lightweight insert 20b can make the center of gravity fall in the lightweight insert 20b, but its center of gravity moves backward relative to the center of gravity of the club head body 10 and the lightweight insert 20 shown in FIG. The two side mass parts 13 and the rear mass part 17 make the club head body 10b form a triangular mass distribution. In this way, the present invention can form a better moment of inertia, so as to further greatly improve the stability of hitting the ball. In addition, the center of gravity can also be kept aligned with the aiming mark 21 , and the center of gravity can also be kept at the same level as the actual hitting point of the striking panel 11 , so as to reduce hitting errors and improve hitting accuracy.

As mentioned above, compared with the disadvantages of the conventional putter head, such as high center of gravity and easy casting defects during the manufacturing process, the present invention can indeed simplify the push rod by properly setting light weight inserts and aiming marks on the putter head body. The structure of the club head reduces hitting errors and improves hitting accuracy.

That is to say, the present invention combines a lightweight inlay at the rear of the strike panel, and forms an aiming mark on the lightweight inlay. Thereby, the center of gravity of the putter head body can be placed on the lightweight insert, so as to form a better relative position among the center of gravity, the aiming mark and the hitting point. Therefore, the present invention can indeed reduce hitting errors, improve hitting accuracy, and simplify the structure of the club head body.
