Referring next to the illustrated embodiment, FIG. 5 shows a cross sectional view of a channel 510 of a golf club head, and FIG. 6 shows a cross sectional view of an insert 620. 7 shows a cross-sectional view of insert 620 located within channel 510. This illustrated embodiment is similar to the embodiment shown in FIGS. 2-4, but in the embodiment of FIGS. 5-7 the channel 510 and insert 620 are asymmetrical about the axis 290 and grooved. Reference numeral 113 is symmetric about the axis 290.

In another illustrated embodiment, FIG. 8 shows a cross sectional view of a channel 810 of a golf club head, and FIG. 9 shows a cross sectional view of an insert 920. 10 shows a cross-sectional view of insert 920 located within channel 810. This embodiment is similar to the embodiment of FIGS. 2-4, but in the embodiment of FIGS. 8-10 the channel 810 and the insert 920 are asymmetrical with respect to the axis 290 and the groove 113 is the axis. It is symmetric about 290.

In another illustrated embodiment, FIG. 11 shows a cross-sectional view of channel 1110 of a golf club head, and FIG. 12 shows a cross-sectional view of insert 1220. 13 illustrates a cross-sectional view of insert 1220 located in channel 1110. This embodiment is also similar to the embodiment of FIGS. 2 to 4. However, the embodiments of FIGS. 8-10 and 11-13 are each more effective than the embodiments of FIGS. 2-3, due to the configuration of channel 810 of FIG. 8 and channel 1110 of FIG. Each of these inserts in the channel can be kept more secure. For example, the opening of channel 810 (FIG. 8) at front face 111 is narrower than the bottom of channel 810, and the opening of channel 1110 (FIG. 11) at front face 111 is channel 1110. Also narrower than the bottom of). Correspondingly, the top of insert 920 (FIG. 9) is narrower than the bottom of insert 920, and the top of insert 1220 (FIG. 12) is narrower than the bottom of insert 1220. In a different embodiment, the insert 1220 of FIG. 12 may be replaced with the insert 3220 of FIG. 32. Insert 3220 (FIG. 32) is similar to insert 1220 (FIG. 12) except that insert 3220 includes two parts, insert 3221 and insert 3222 (FIG. 32). Do. Using insert 3220 (FIG. 32) instead of insert 1220 (FIG. 12) within channel 1110 (FIG. 11) may facilitate inserting an insert into the channel.

14 shows a cross-sectional view of the insert 210 of FIG. 4 located in the channel 1110 of FIG. 11, according to another embodiment. This embodiment is also similar to the embodiment of FIGS. 2 to 4. However, in the embodiment of FIG. 14, the cross-sectional area of the channel 1110 is greater than the sum of the cross-sectional areas of the insert 220 and the groove 113. In particular, the cross-sectional area of the channel 1110 is greater than the sum of the cross-sectional areas of the insert 220 and the groove 113 by one or more intervals or the cross-sectional area of the remaining region 1444. In this embodiment, an adhesive may be disposed in the channel 1110 and at least a portion of the adhesive may be located in the residual area 1444. The presence of residual region 1444 allows the use of more adhesive in this embodiment of FIG. 14 than the embodiments of FIGS. 2-4 and other embodiments. The use of more adhesive can more securely retain the insert 220 in the channel 1110. By way of example, the portion of the residual region 1444 may have a width of approximately 0.3 mm to 0.1 mm. In this embodiment, the adhesive may be epoxy.

Referring to a different embodiment, FIG. 15 shows a cross-sectional view of insert 1520, and FIG. 16 shows a cross-sectional view of insert 1520 located within channel 210 of FIG. 3. This embodiment is also similar to the embodiment of FIGS. 2-4, but in the embodiment of FIGS. 15-16 the groove 1613 is shallower than the groove 113 of FIGS. 2-4.

FIG. 17 illustrates a cross-sectional view of channel 1710 of a golf club head according to another embodiment, and FIG. 18 illustrates a cross-sectional view of insert 1820 of this embodiment. 19 shows a cross-sectional view of insert 1820 located within channel 1710. This embodiment is similar to the embodiment of FIGS. 2-4, but there are also many differences between these two embodiments. For example, in FIGS. 17-19, channel 1710 and insert 1820 are asymmetric about axis 290. In addition, portions of the channels 1720 form portions of the grooves 113, and portions of the inserts 1920 form different portions of the grooves 113. In one example of the illustrated embodiment of FIG. 19, adhesive is used to couple insert 1820 to channel 1710.

In this embodiment, the insert 1820 may comprise a material that is harder or softer than the striking surface 111 of the golf club head body forming the channel 1710. For example, if the first edge of the groove 113 closer to the sole of the golf club head body wears out faster than the second edge of the groove 113 typically closer to the upper rail of the golf club head body, insert 1820 ) May be located at the first edge of the groove 113 and may comprise a harder material than the striking surface 111. In this example, the first edge and the second edge of the groove 113 may wear more evenly with respect to each other. In a different example, if the first edge of the groove 113 typically wears slower than the second edge of the groove 113, then the insert 1820 will be inserted into the groove (eg, when the insert 1820 comprises a softer material than the striking surface). May still be located at the first edge of 113). Other variations are also possible.

Referring to the next embodiment, FIG. 20 shows a cross-sectional view of insert 2020, and FIG. 21 shows a cross-sectional view of insert 2020 positioned within channel 210 of FIG. 3. This embodiment is also similar to the embodiment of FIGS. 2-4, but in FIGS. 20 and 21, insert 2020 includes two portions or inserts 2021, 2022. In the embodiment of FIGS. 20-21, each portion of insert 2020 forms a different portion of groove 2113. The groove 2113 may be shallower than the groove 113 of FIGS. 2 and 3. In different embodiments, insert 2020 may include three or more portions, and each portion of insert 2020 may form part of groove 2113. In other embodiments, insert 2020 may comprise two or more portions, one or more of the portions of insert 2020 form grooves 2113, and one or more other portions of insert 2020 may be grooves ( Does not form part of 2113). As another variant, one or more portions of the channel may also form part of the groove. Moreover, different portions of insert 2020 may comprise the same material, or may comprise different materials. For example, for reasons similar to those described with reference to the previous embodiments of FIGS. 17-19, insert 2021 may comprise a first material, and insert 2022 may be harder than the first material. It may include two materials. In one example of the illustrated embodiment of FIG. 21, adhesive may be used to couple the inserts 2021, 2022 to the channel 210.
