Definitions

  • golf club heads of the iron type are made of metal, and many have recesses for receiving an insert for the striking face.
  • golf club irons are either blades or have a cavity back defined by redistributing the weight of the club head around the perimeter thereof.
  • Perimeter weighted clubs are recognized as increasing the moment of inertia, which increases head stability and lessens head rotation that imparts side spin on the ball. Accordingly, with perimeter weighted clubs, a golfer can hit a straighter shot, even when the ball is not struck in the center or "sweet spot" of the club face.
  • Metal golf club irons are generally forged or cast in a mold.
  • Forged club heads are generally softer and provide a greater feel to the golfer, while cast club heads are harder because they can be formed of a higher strength metal than forged club heads.
  • the present invention relates to an improved perimeter weighted club head including an insert for the striking face which is formed of a high strength material.
  • the Mahaffey patent discloses a laminated lightweight insert for golf club heads of both the wood and iron type.
  • the Anderson patents disclose iron type golf club heads having a cast metal head and a forged insert for the striking face. While these prior heads perform satisfactorily, they do not afford the golfer with the desired feel when striking a golf ball.
  • an iron golf club head has a first recess extending rearwardly of the striking face and an undercut recess which extends toward the top and bottom wall of the head behind the striking face.
  • Such a head is an improvement over the prior perimeter weighted heads but still lacks a concentration of weight toward the bottom of the head.
  • an iron type golf club head including a body having top, bottom, toe and heel portions and a striking face area containing a recess.
  • An insert is secured within the recess, with an outer surface of the insert being flush with a non-recessed portion of the striking face area.
  • the bottom portion of the body comprises the sole of the club head. It extends rearwardly and upwardly from the lower portion of the striking face area in spaced relation from the rear surface of the insert to define an undercut area in the sole behind the insert.
  • the weight of the club head is thus distributed around the perimeter of the body and toward the sole to increase the moment of inertia and decrease rotation of the club head when it strikes a golf ball.
  • the thickness of the sole at the rear of the undercut is less than the thickness of the insert.
  • the upwardly extending portion at the rear of the sole terminates in a top wall which is below the vertical midpoint of the body to concentrate the weight of the head toward the bottom.
  • the sole top wall extends between the toe and heel portions of the body and has a convex configuration.
  • the head body portion is formed of a forged metal such as carbon steel and the insert is formed of a high strength metal such as hardened steel or a rolled sheet material. With such a combination of materials, the golf club head provides improved feel to the golfer and the high strength insert provides maximum distance to the flight of the golf ball.
  • Fig. 1 is a front plan view of the iron type golf club head according to the invention.
  • Fig. 2 is a left side view of the head of Fig. 1;
  • Fig. 3 is a rear plan view of the head of Fig. 1 ;
  • Fig. 4 is a sectional view of the head taken along line 4-4 of Fig. 1.
  • the golf club head 2 includes a frame or body 4 having toe 4a, heel 4b, top 4c and bottom 4d portions and a striking face area 6 containing a recess 8.
  • An insert 10 is secured within the recess, preferably by welding although other conventional connection methods may be used.
  • the outer surface 10a of the insert is substantially flush with a non- recessed portion 6a of the striking face area.
  • the body 4 is preferably formed of a forged metal such as carbon steel having an amorphous microstructure and the insert is formed of a high strength material such as hardened steel.
  • a hardened steel is a high chrome content steel known as alpha Maraging steel.
  • the insert can also be formed of a rolled sheet material or a forged metal.
  • the bottom portion 4d of the body comprises the sole of the club.
  • the bottom portion extends rearwardly 4e from the front of the club and upwardly 4f to a location below the top portion 4c of the body and spaced from the rear surface of the insert.
  • the sole thus defines an undercut area 12 in the bottom portion of the body behind the insert.
  • the thickness t of the body at the intersection of the rearwardly extending sole bottom portion 4e and the upwardly extending sole bottom portion 4f is less than the thickness of the insert.
  • the thickness of the insert is between 1.0 and 4.0mm, a preferably between 2.0 and 2.5mm, the thickness t is less than the insert thickness.
  • the forward surface of the upwardly extending sole bottom portion 4f is preferably parallel to the rear surface of the insert so that the width of the undercut area defined between the insert 10 and the portion 4f is constant.
  • the forward surface of the upwardly extending sole bottom portion 4f may be angled inwardly as shown in phantom in Fig. 4 so that the width of the undercut area tapers toward the bottom thereof.
  • the top wall 4g of the upwardly extending sole bottom portion 4f extends between the toe and heel portions of the body and has a convex configuration as shown in Fig. 3.
  • the top wall is arranged below the vertical midpoint of the body so that the weight of the body is concentrated toward the bottom portion of the body. Since the body contains a recess, weight is also distributed about the perimeter of the body. This weight distribution increases the moment of inertia of the club head and decreases rotation of the head when it is used to strike a golf ball.
  • the iron type golf club head of the invention provides improved feel to the golfer because the forged body is softer and thus provides feedback to the golfer when a ball is struck. Maximum distance in the flight of the ball is obtained by using the higher strength insert.
  • the perimeter weighting of the club provides a larger "sweet spot" in the club striking face so that less precision is required when hitting the ball.
  • the concentration of weight toward the bottom of the head increases the trajectory of the ball and enables the golfer to get the ball airborne from difficult lies.

Abstract

Une tête de club de golf de type en fer à insert haute résistance comprend un corps forgé comportant une zone de face de frappe qui comprend un renfoncement et un insert haute résistance solidarisé à l'intérieur du renfoncement avec une surface externe du renfoncement affleurée à une partie non renfoncée d'une zone de face de frappe. Le fond de la partie corps fait saillie vers l'arrière et vers le haut pour définir une zone évidée dans la partie de fond derrière l'insert. Grâce au renfoncement et la zone évidé, le poids du corps est réparti autour du périmètre et vers le fond de manière à augmenter le moment d'inertie et diminuer la rotation de la tête du club.
