Definitions

  • the present invention relates to a golf club head and more particularly relates to an improvement of the golf club head revealed in Swedish Patent Application 8101069-6.
  • Said head comprises a core body of a first plastics material and a housing tightly surrounding the core body, said housing having a lateral opening which defines a free striking surface on the core body, said core body having an exterior shape and dimensions essentially corresponding to the exterior shape and dimensions of the finished club head and said housing having the shape of a relatively thin-walled shell of at least one other plastics material which has a higher modulus of elasticity than the first plastics material and which surrounds the core body while exerting an initial stress thereon, said core body having a cavity, the walls of which are at least partially covered by a shell portion made in one piece with the shell, said shell portion defining an interior chamber the bottom of which is covered by a sole plate.
  • a bracing wall be arranged which extends transversely to the striking surface from the rear wall, as viewed in the direction of swing, of the chamber towards the forward wall of the chamber and in that a heel-like projection is arranged on the forward wall of the chamber directly in front of the end surface of the bracing wall, whereby the facing end surfaces of the bracing wall and the heel define an upwardly narrowing slot.
  • the wedge-shaped slot between the end surface of the bracing wall and the heel will result in an asymmetrical deformation of the impact wall, so that it will yield more towards the bottom of the club head, whereby the ball will be imparted a back-spin when leaving the club head, which is desirable for the golfer to obtain an ideal ball path.
  • Fig 1 is a view from below of the golf club head according to the invention and Fig 2 is a cross-section along the line II-II in Fig 1.
  • the embodiment of the golf club head shown comprises a core body 1 which is made of a suitable plastics material of high modulus of elasticity, e.g. a polyamide plastic, such as "ZYTEL" ® .
  • the core body 1 has essentially the same exterior shape as the intended finished club head, but is proportionally somewhat smaller.
  • the core body 1 is surrounded by a housing, or shell 2 of a suitable plastics material which has a higher modulus of elasticity than the material in the core body 1, e.g. a carbon fiber reinforced poly amide plastic, such as nylon, which is, for example, extruded about the core body 1, so that the shell 2 surrounds and is in tight contact with the outside of the core body 1 except along an essentially flat surface 3 which forms the striking surface of the club head.
  • the core body 1 has an essentially centrally located cavity 4, which opens towards the bottom of the club head.
  • This cavity 4 is at least partially covered by a shell portion 5 integral with the shell 2 and defining an inner chamber 6.
  • the cavity 4 and the shell portion 5 create a rectangular box-shape, as shown in Fig 1, with the shell portion 5 side 7 adjacent to the striking surface 3 being possibly completely or partially removed to reveal the core body 1.
  • a sole plate 8 is mounted on the bottom of the club head covering the chamber 6.
  • a bracing wall serving as an anvil extends from the rear wall 10, as viewed in the direction of swing, of the chamber 6 towards the forward wall 7 of the chamber.
  • a heel 11 projects backwards from said forward wall 7 and is directly opposite the end surface 12 of the bracing wall 9 (see Fig 1).
  • the facing end surfaces of the bracing wall 9 and the heel 11 define between them a slot which narrows upwardly.
  • the heel 11 is designed to limit the movement backwards of the impact wall 14 when the ball is struck by abutting against the striking surface 12 of the bracing wall.
