Definitions

  • FIG. 12 illustrates a cross-section of an insert received within the back cavity of an iron-type golf club head.
  • FIG. 13 illustrates an exploded view of an embodiment of an insert.
  • the insert comprises multiple insert sections 224 as described above, but each of the plurality of insert sections 224 consists of only a single cap portion 222, having no elastomeric portion 212 between the adhesive layer 204 and the cap portions 222.
  • the adhesive layer 204 is, again, a single continuous piece.
  • the insert sections 224 consists only of the cap portions 222 attached directly to the adhesive layer 204.
  • the adhesive layer 204 is not completely covered by the insert sections 224 (cap portions 222); instead, the insert sections 224 (cap portions 222) are separated by gaps 240 between the spaced-apart, outside edges of the insert sectionsfcap portions 222) defined by the uncovered areas of the adhesive layer 204.
  • the heel side section 451, the toe side section 452, the top section 453, and the bottom section 454 form an intersection wherein one corner, vertex, or edge of each of the sections can be adjacent to the geometric center 140 of the strikeface 110.
  • the heel side section 451 , the toe side section 452, the top section 453, and the bottom section 454 form a center gap 441 adjacent to the geometric center 140 of the strikeface 110.
  • a corner, vertex, or edge of each of the sections 424 forms a perimeter of the center gap 441 .
  • Referring to Figures 10-13 illustrate the sections 424 forming the center gap 441 and the gap perimeter.
  • a curved edge of the top section 453, a curved edge of the bottom section 454, a vertex of the heel side section 451, and a vertex of the toe side section 452 form the center gap 441 and the perimeter of the gap.
  • the first insert was the flexible insert 300 described in the first embodiment above.
  • the second (control) insert was exactly identical to the first insert. 300, except lacking the gaps creating separate sections or panels.
  • the first embodiment insert 300 with a plurality of insert, sections 324 having gaps 340 between them showed improved performance (as discussed below) over the identical comparison insert (in the control club) that, had continuous, unbroken adhesive, elastomeric, and cap layers. Both were placed in identical 7-iron golf club heads having a loft of 29 degrees.
  • the test incorporated player testing, robotic testing, and FEA simulation. The player test had 20 players each hitting ten shots with each of the two golf 7-iron golf clubs.
  • the iron-type golf club head and insert design were identical between the flexible (with gaps) and stiff (without gaps) inserts, except that the flexible insert 300 had the gaps 340 and insert sections 324 as described in the first insert. 300 embodiment.
  • the iron-type golf club head having flexible insert 300 comprising the gaps 340 and insert sections 324 provided an almost 1 mile per hour higher initial ball speed than the iron-type golf club head comprising the insert without gaps. The additional ball speed upon impact results from less energy lost during the ball impact due to the flexibility provided by the insert gaps.
