Abstract

A golf club having a head wherein there is disposed a relatively strong but lightweight unit-cell structure portion between the head''s toe and heel portions and immediately behind its generally planar impact face so that the weight of the head is concentrated at the toe, the toe and heel, or the toe, heel and sole portions in order to provide a relatively stiff and wider effective hitting area along with a relatively lower center of gravity, the unit-cell structure in an iron configuration, for example, including a plurality of parallel tubular elements extending generally perpendicular to the plane of the impact face.

Claims (18)

1. A golf club, comprising: an elongated shaft having a lower end; and a head having a hosel in an upper portion thereof, said lower end of said shaft being fixedly disposed in said hosel, said head also having a toe portion and a heel portion and a generally planar high modulus impact face between said toe and heel portions, said head portion having hollow unit-cell structure means disposed therein immediately behind said impact face for broadening the effective hitting area of said impact face while reinforcing and enhancing the stiffness of said impact face, said unit-cell structure means including a plurality of interconnected elongated unit-cells encapsulatEd by other interconnected elongated unit-cells, each of the unitcells being defined by boundary cell walls, each boundary cell wall having a cross sectional thickness substantially less than the average of the largest and smallest external cross sectional dimension of the bounded unit cell, said boundary cell walls extending generally rearwardly from and generally perpendicularly to the plane of said impact face.
2. The golf club according to claim 1, wherein said unit-cell structure means is disposed in a hollowed out cavity portion of said head.
3. The golf club according to claim 1, wherein said club is an iron and said unit-cell structure means is disposed in a rearward exposed cavity section, said means extending from a rear surface situated immediately behind said impact face, said impact face and said rear surface defining a relatively thin impact wall therebetween.
4. The golf club according to claim 3, wherein said boundary cell walls define a honeycomb core structure.
5. The golf club according to claim 4, wherein said boundary cell walls of said honeycomb core structure have a hexagonal cross section.
6. The golf club according to claim 4, wherein said boundary cell walls of said honeycomb core structure have a rectangular cross section.
7. The golf club according to claim 4, wherein said boundary cell walls of said honeycomb core structure have a triangular cross section.
8. The golf club according to claim 4, wherein said boundary cell walls of said honeycomb core structure have a circular cross section.
9. The golf club according to claim 1, wherein said club is a wood and the unit-cells define a plurality of elongated hollow bores in said head extending rearwardly from a forwardly disposed impact plate, said impact face being the outer surface of said impact plate.
10. The golf club according to claim 9, wherein said bores terminate at their rearward end in a common plane defining a rearward wall of said unit-cell structure means, and wherein said impact plate, said rearward wall and the bore configuration in said head define a sandwich honeycomb structure.
11. The golf club according to claim 9, wherein said hollow bores have a generally circular cross section.
12. The golf club according to claim 9, wherein said hollow bores have a generally ellipsoid cross section.
13. The golf club according to claim 9, wherein said bores have differing cross sectional dimensions.
14. The golf club according to claim 1, wherein said club is a wood and said head includes a cavity therein, said unit-cell structure means being at least partially disposed therein.
15. The golf club according to claim 14, wherein said unit-cell structure means includes a face plate and wherein the unit-cells of said unit-cell structure means define a prefabricated honeycomb core structure disposed in said cavity the rearward end of which being bonded to the rearward wall of said cavity and the forward end of which being bonded to the inner wall of said face plate to define a sandwich honeycomb structure.
16. The golf club according to claim 15, wherein said boundary cell walls of the unit-cells define in cross section a curved geometric pattern.
17. The club according to claim 15, wherein said boundary cell walls of the unit-cells define in cross section a multiple straight sided geometric pattern.
18. The golf club according to claim 14, wherein the unit-cells of said unit cell structure means define a prefabricated honeycomb core structure disposed in said cavity the rearward end of which being bonded to the rear wall of said cavity and the forward end of said core structure being spaced from and behind said impact face, said core structure including a barrier wall disposed transversely to the longitudinal axis of said core structure and spaced a relatively short distance behind said forward end of said core structure, said impact face being of a relatively hard plastic material that extends into said core structure only to sAid barrier wall.
