Golf club with golf club head having compressible v-shaped grooves

An iron-type golf club, comprising:

• a club shaft;
• an iron-type golf club head configured at one end of the club shaft and having a club face constructed from a first material;
• a plurality of grooves formed in the club face including a first groove and a second groove separate from the first groove, each of the first and second grooves being defined in the first material and including an open front end, a top surface, a bottom surface opposite the top surface, and a closed end surface connecting the top surface and the bottom surface and located opposite the open front end;
• a first insert arranged within the first groove, the first insert being formed of a material having a softer durometer than a durometer of the first material, the first insert having a v-shaped end exposed at the open front end of the first groove and configured to be compressed when the club face strikes a golf ball, wherein portions of the first groove adjoining the first insert are configured to impart spin on the golf ball when the club face strikes the golf ball;
• and
• a second insert arranged within the second groove, the second insert being formed of a material having a softer durometer than the durometer of the first material, the second insert having a v-shaped end exposed at the open front end of the second groove and configured to be compressed when the club face strikes a golf ball, wherein the second insert is a separate and independent part from the first insert, and wherein portions of the second groove adjoining the second insert are configured to impart spin on the golf ball when the club face strikes the golf ball, and
• wherein the first and second inserts are compressible with respect to the first and second grooves, respectively, in which they are mounted such that the open ends of the first and second grooves provide a v-shaped cross section when the first and second inserts are in an uncompressed state and such that the open ends of the first and second grooves provide a u-shaped cross section when a golf ball is struck at the first and second grooves to thereby compress the first and second inserts.

• an iron-type golf club head arranged at one end of the club shaft and having a club face formed of a first material;
• a plurality of grooves formed in the club face including a first groove and a second groove separate from the first groove, each of the first and second grooves being defined in the first material and having a rectangular cross section including an open front end, a top surface, a bottom surface opposite the top surface, and a closed end surface connecting the top surface and the bottom surface and located opposite the open front end;
• a first compressible support arranged within the first groove and formed of a second material, the second material being softer than the first material, the first compressible support configured to be compressed when the golf club strikes a golf ball;
• a second compressible support separate and independent from the first compressible support and arranged within the second groove, the second compressible support being formed of the second material and configured to be compressed when the golf club strikes a golf ball;
• a first insert arranged within the first groove, wherein the first compressible support is located between the first insert and the closed end surface of the first groove, the first insert being formed of a third material and having a v-shaped end exposed at the open front end of the first groove;
• and
• a second insert arranged within the second groove, wherein the second compressible support is located between the second insert and the closed end surface of the second groove, the second insert being formed of the third material and having a v-shaped end exposed at the open front end of the second groove, wherein the second insert is a separate and independent part from the first insert, and
• wherein the first and second compressible supports are compressible with respect to the first and second grooves, respectively, in which they are mounted such that the open ends of the first and second grooves provide a v-shaped cross section when the first and second compressible supports are in an uncompressed state and such that the open ends of the first and second grooves provide a u-shaped cross section when a golf ball is struck at the first and second grooves to thereby compress the first and second compressible supports.

An iron-type golf club head, comprising:

• a striking face constructed from a first material;
• a plurality of grooves including a first groove and a second groove separate from the first groove formed in the striking face, each of the first and second grooves having a rectangular cross section and being defined in the first material, and each of the first and second grooves including an open front end, a top surface, a bottom surface opposite the top surface, and a closed end surface connecting the top surface and the bottom surface and located opposite the open front end;
• a first insert arranged within the first groove, the first insert having a v-shaped end exposed at the open front end of the first groove, and the first insert being made from a material having a compressibility greater than a compressibility of the first material;
• and
• a second insert arranged within the second groove, the second insert having a v-shaped end exposed at the open front end of the second groove, and the second insert being made from a material having a compressibility greater than a compressibility of the first material, and
• wherein the first and second inserts are compressible with respect to the first and second grooves, respectively, in which they are mounted such that the open ends of the first and second grooves provide a v-shaped cross section when the first and second inserts are in an uncompressed state and such that the open ends of the first and second grooves provide a u-shaped cross section when a golf ball is struck at the first and second grooves to thereby compress the first and second inserts.
