Definitions

  • This invention relates to golf clubs and more particularly to an improved face plate construction for a metal wood configuration golf club head.
  • the golf club head of the present invention provides an improvement over prior art heads in that it utilizes a face plate of non-metallic material which is supported by a thin reinforcement plate interposed between the face plate and the head hollow or cavity. This result is achieved without greatly increasing the cost or weight of the wood type head by forming the main body of the head and the reinforcement plate as an investment casting of a material such as stainless steel, beryllium copper, titanium, or aluminum, and then attaching the non-metallic face plate to the reinforcement plate, in a recess formed by the latter.
  • the thin non-metallic face plate when reinforced as disclosed herein, slightly compresses when impacted by the ball, and restores as the ball leaves that face plate as aided by flat spring . action of the reinforcing metal plate, to enhance ball and driving control; also the sound of face plate impact with the ball is favorable .and desirable.
  • the invention is- embodied in a golf club head that includes: a) a main body portion formed by an investment casting of a first metallic material, and forming a cavity, b) a front face reinforcement plate formed of meta.llic material, only the periphery of the face reinforcement plate being integral with the main body portion to support the plate, the plate forming a recess bounded by a peripheral lip, c) and a non-metallic ball striking second plate received in that recess and retained therein.
  • the main body portion of the head and the reinforcement plate may consist essentially of a cast metal selected from the group consisting of steel, beryllium copper, and aluminum; and the second, i.e. outer face plate typically consists of a material selected from the group consisting of graphite, ceramic, and KEVLAR.
  • the second plate is preferably bonded to the reinforcement plate and compressed to peripherally pressurally engage the lip bounding the recess, graphite being a preferred material for this purpose.
  • the second plate typically has generally trapezoidal forward facing configuration with top and bottom elongated, shallowly curved extents, the top curved extent being upwardly convex, and the bottom curved extent being downwardly convex; and it may have sideward extents respectively convex toward the club head toe and heel.
  • the method of forming the metallic golf club head, of wood configuration includes the steps
  • Another object is to provide a method as referred to which includes the step of grinding the lip and said second plate to form a forwardly facing smooth ball striking head surface wherein the forward face of the non-metallic second plate is flush with the forward facing surface of the peripheral metallic lip.
  • Such grinding is typically carried out to reduce the thickness of the graphite plate to a thickness of about 2 mm, and the metallic reinforcement plate also having about the same thickness, so as to flex slightly, as the graphite plate is compressed, during ball impact. This combination of compression and flexing aids in providing favorable ball striking and control, during the swing of the club.
  • a further object is to provide a forged metal plate carrying the graphite plate, and welded to a cast head main body portion, to enhance strength and weight re-distribution.
  • Fig. 1 is a front elevational view of a club head embodying the invention
  • Fig. 2 is a section taken on lines 2-2 of Fig. 1;
  • Fig. 3 is a fragmentary section taken on lines 3-3 of Fig. 1;
  • Fig. 4 is a sectional view like that of Fig. 2, but showing the method of assembling and shaping the non-metallic front plate as well as the lip of the metallic body;
  • Fig. 5 is a block diagram showing certain steps carried out in forming the club head
  • Fig. 6 is a view like Fig. 2, showing a modification; and Fig. 7 is a frontal view of the Fig. 6 head.
  • a golf club head 10 includes a thin top wall 11, upwardly crowned; a thin flat bottom wall or sole 12; a thin toe wall 13; a thin heel wall 14; a thin rear wall 15; and a hosel 16 to which a golf club shaft 16A is suitably connected.
  • Elements 11-15 define a main body portion formed, for example, by investment casting indicated at 50 in Fig. 5, using metallic material such as stainless steel, aluminum, beryllium copper, titanium, etc.
  • the head has the configuration of a golf "wood 11 head, and forms a hollow or cavity 17.
  • the head also includes a front face reinforcement plate 18, which typically is formed of the same material as the main body portion of the head. It may be investment cast at the same time as the main body portion, and is integral with the latter.
  • the principle extent of the plate 18 facing the cavity 17 is un-supported, i.e. only the plate looping periphery is joined to the main body portion, to support the plate.
  • the plate is thickened to form a peripheral lip 23 that loops about, or bounds, a recess 22 extending parallel to and at the immediate front side of the plate 18.
  • a non-metallic ball striking second plate 25 is received or inset in the recess and retained therein.
  • Plate 25 is affixed to reinforcement plate 18, and inner wall 23a of lip 23.
  • the bounding edge or rim 25A of plate 25 firmly presses against wall 23A to form a tight fit therewith.
  • the front plate 25 may be slightly oversized (peripherally) when pressed into position in the recess; also, the plate 25 may have oversized thickness t, (see Fig. 4) when pressed into the recess.
  • This step is indicated at 52 in Fig. 5. See force arrows F, in Fig. 4.
  • Epoxide resin may be employed at the interface 26 between plates 18 and 25, and also at the peripheral interface between 25a and 23a, to bond the plate 25 in position. See step 51 in Fig. 5.
  • the plate 25, and the bounding lip 23, are typically ground down to a level or plane indicated by broken line 28 in Fig. 4, to create a flush interface as seen at surfaces 25c and 23c in Fig. 2. See step 53 in Fig. 5.
  • Polished surface 23c bounds the plate 25, as in a modified trapezoidal loop, clearly indicated in Fig. 1.
  • plate 25 has upper and lower outwardly shallowly convex edges 25d and 25e_, and left and right outwardly shallowly convex edges 25£ and 25g;, with rounded corners at 25h-25k.
  • Plate 18 has the same general peripheral configuration, to co-act with plate 25 but in a flexing rather than a compressive manner during ball striking, referred to below.
  • the plate 25 preferably consists of graphite, such as a composite of graphite fibers; however, other materials such as ceramic or KEVLAR may be employed.
  • the final thickness of the plate 25 indicated at t 2 in Fig. 2 is about 2 mm; and the thickness t 3 of reinforcement plate 23 is also about 2 mm, over their bonded together extents.
  • the plate 25 when striking a golf ball at high head speed, as during a golf swing, the plate 25 slightly resiliently compresses, and the plate 23 slightly flexes, plate 25 serving to spread the compressive force application over area of plate 23.
  • the combination of local compressive deflection of plate 25 and flexing of plate 23 serves to control ball handling and distribute impact loading during contact of the ball with the head.
  • the lightweight, non-metallic plate 25 also enables some reduction in thickness of heavier metal plate 23, without diminution of total strength of both plates.
  • Fig. 2 indicates a plugged port 45, via which synthetic resin may be introduced, prior to plugging. Other known techniques of resin fill into a hollow cavity may be employed.
  • Reinforcement plate 118 (corresponding to plate 18) is here a forged metal plate which is welded to the head main body portion (casting) 11-15.
  • the forged metal plate has a looping periphery 118a welded to the main body portion. See looping weld 150, which is generally trapezoidal and is intersected by a plane 151 defined by the second plate 25. The latter is the same as in Figs. 1-5, and may be press-fitted into plate 118..
  • the head main body portion (casting) has a lip 123 (corresponding to lip 23) which defines a looping recess 153 that receives the looping periphery of the plate 118, the latter seated on a ledge or ledges 154 formed by the lip 123.
  • Weld 150 also extends in the recess 153.
  • Both the recess 153 and plate periphery 118a. are generally trapezoidal about the second plate 25.
  • the forged plate 118 and head main body portions 11-15, and 123 may both consist of the same metal, such as stainless steel. After assembly, the elements 123, 150, 118 and 25 may be surface ground, as described before, as in Fig. 4.
  • a forged metal plate 118 provides enhanced strength for absorbing golf ball impact loading from plate 25 (and distributed by plate 25) ; and the thus enabled reduced thickness of the plate 118, together with the trapezoidal configuration of weld metal, enables increased head weight distribution toward the toe and heel, as is desired to resist head twist during such ball impact, while also benefitting from the advantage of non-metallic plate 25, as described.
