Abstract

A metalwood type golf clubhead including a clubhead body having a toe, heel, upper crown surface, bottom sole surface, side surfaces, rear surface and ball-striking clubface having at least one raised, elongated, aerodynamically shaped reinforcing and stabilizing member extending outwardly from the upper and/or bottom surfaces, and having a front ball-striking surface located perpendicular to and coincident with the ball-striking clubface. The structure provides improved weight distribution for better balance, additional strength and stability to clubhead and provides more effective aerodynamic surfaces to increase clubhead speed.

Description

    BACKGROUND AND SUMMARY OF THE INVENTION
  • The present invention, specifically relates to wood-type traditional shaped clubheads having a reinforcing and stabilizing (R/S) member, including ball-striking surfaces coincident with the clubface and located verticallyin a perpendicular plane, above and/or below, the clubface of a traditional shaped clubhead. [0001]
  • Most wood-type traditional shaped clubheads are currently made of metal, either totally of steel, titanium, or combined with other alloys. Other clubheads include a shell made of a steel with a face insert that is made of titanium or similar lighter weight material. This permits clubheads to be much larger, yet meet the accepted weight parameters for the respective drivers and fairway type metalwoods. [0002]
  • Although these wood-type traditional shaped clubheads have been substantially enlarged overall, having higher clubfaces with wider, bulkier crowns and sole bottoms, their clubfaces have not increased the effective ball-contact hitting area, horizontally or vertically, proportionately to the overall enlarged clubheads for improved performance, especially for most golfers. To keep the overall clubhead size larger, and lighter, as currently demanded by most higher handicap golfers, the structural integrity of the side walls and the clubfaces, is often compromised. This causes stress cracks, unstable clubhead control at ball contact, and erratic ball flight control, resulting in loss of distance, accuracy, and inability to produce reassuring and repeating solid ball contacts, even when hit flush. [0003]
  • Many attempts have been made to reinforce the traditional shaped metal wood type clubheads as shown and described in the prior art. U.S. Pat. No. 3,847,399, to Raymont reinforces the back of the clubface with a honeycomb structure. My U.S. Pat. No. 5,141,230 reinforces the interior of a metalwood with a first mass located behind the ball-striking face, and my U.S. Pat. No. 5,482,279 provides an interior peripheral mass basically along the inner periphery, of the clubhead shell behind the clubface. My U.S. Pat. No. 5,989,134 reinforces the outer side walls, rear, bottom and crown areas of a wood-type golf clubhead. U.S. Pat. Nos. 4,162,794 and 4,319,752 to Thompson show golf clubheads with a downwardly projecting keel, which is coincident with the ball-striking clubface. [0004]
  • The ball-striking surface, on clubfaces of traditional shaped metalwood-type clubheads, diminishes dramatically, from the actual point where the crown or top section interfaces with the uppermost portion of the clubface. From this upper demarcation point or common border of the clubface, the outer shape, at both the toe and heel sections of the clubface, are traditionally in a downward and inward direction. his greatly reduces the size of the ball-contact area, available on the traditional shaped metalwood clubfaces. Various attempts at enlarging the ball contact area have been made by altering the overall shape of the clubhead, as shown in the patents to Adams, U.S. Pat. Nos. 5,465,970 and 5,931,745, among others. [0005]
  • A primary concept of the present invention provides traditional shaped wood-type golf clubheads with at least one raised reinforcing and stabilizing member, which adds additional ball striking area to a traditional-sized ball-striking clubface, either upwardly or downwardly in a vertical direction when the clubhead is on the ground surface in a normal address position. This increased ball contact area of the RIS member is specifically formed in a perpendicular or vertical plane, in a top to bottom direction of the clubface. The addition of the reinforcing and stabilizing member of the present invention, includes a ball-striking surface coincident with and located perpendicular to a traditionally, diminished size, shaped clubface, increases the overall height of the ball striking clubface, providing a considerably expanded area to strike a golf ball. The smaller raised reinforcing and stabilizing (R/S) member formed above or below the clubface will always be substantially shorter in a heel to toe direction; than the traditional sized clubhead body. [0006]
  • Lower handicap golfers, may prefer a smaller traditional shaped clubhead with effective, expanded ball-striking surfaces located above and/or below the clubface. This R/S embodiment locates a much larger concentration of mass above the clubface and closer to the center of gravity and produces a more solid response from ball-contacts, which are made closer to the center of gravity, by the most proficient golfers. [0007]
  • The versatile concept of the present invention includes distinctively different aerodynamically designed reinforcing and stabilizing members that perform totally different functions on the clubheads, independently of each other. The ball-striking surfaces that are coincident with and/or perpendicular to the clubface may be located separately and/or independently, at different sections of the clubhead, to produce preferred and specifically different functions. The unique structural concept of the present invention permits combining the advantages of distinctively different reinforcing and stabilizing R/S members, in shape and size, which are formed at different locations on the clubhead. The frontal ball striking surfaces of the reinforcing and stabilizing R/S members are coincident with and perpendicular to the clubface on the traditional shaped clubhead to produce improved functions in a superior high-performing clubhead. [0008]
  • Locating a reinforcing and stabilizing member with ball-string surfaces coincident with the clubface, above and/or below the clubface, substantially increases the reduced ball-striking area on the clubface of a traditional shaped clubhead. In addition, the unusual structure of the present invention, not only minimizes or eliminates undesirable shocks and vibrations of “thin” shots, but produces a most formidable clubhead stability, even when the most severe off-center ball contacts occur at the extreme toe, heel or lowest portion of the clubface. [0009]
  • A first preferred embodiment of the present invention includes at least one raised reinforcing and stabilizing (R/S) member, with a front ball-striking surface that forms only a downsized smaller top crown section on a traditional shaped clubhead located above and perpendicular to the clubface, which vertically expands the hitting area of the clubface of a traditional shaped clubhead, in a top to bottom direction. The R/S front ball-striking surface extends to and is coincident with a central, upper portion of the ball-striking surface of the clubface. The multi-functional capabilities of the reinforcing and stabilizing member, provides an upwardly expanded, centrally located, ball-contact area that creates a deeper-type clubface on a traditional shaped clubhead. The reinforcing and stabilizing member with a frontal ball-striking surface can be coincident with and located perpendicular to the lower portion and/or the upper portion of the clubface, enlarging it substantially in a vertical direction, thereby providing additional ball-striking area on the clubface of a traditional shaped metalwood-type golf clubhead. [0010]
  • The reinforcing and stabilizing member is located on an upper portion of the clubhead and includes a front ball-striking surface that extends to and is coincident with the central upper portion of the ball-striking clubface. [0011]
  • Another preferred embodiment of the present invention, provides a reinforcing and stabilizing member with a ball-striking surface, located below and perpendicular to the clubface. This unique additional expanded hitting area below the clubface, is formed by a front ball-striking surface of the reinforcing and stabilizing member, which is coincident with and below the clubface, and is located on the bottom of a traditional shaped clubhead. The reinforcing and stabilizing member extends rearwardly from the ball-striking clubface. This embodiment of the present invention, provides an reinforcing and stabilizing member, including a front ball striking surface, located at the extreme lower portion of the clubface. The lower reinforcing and stabilizing member, located on the bottom of a traditional shaped clubhead, and having a ball striking surface coincident with and perpendicular to the clubface, extends rearwardly therefrom. [0012]
  • Another embodiment includes two distinctively separated reinforcing and stabilizing members, both including front ball-striking surfaces located above and perpendicular to the clubface of a traditional shaped clubhead. [0013]
  • Still another embodiment includes two separated reinforcing and stabilizing R/S members including front ball-striking surfaces located below and perpendicular to the clubface of a traditional shaped clubhead. [0014]
  • Yet another embodiment includes two separated reinforcing and stabilizing R/S members including front ball-striking surfaces, one located above the clubface and another located below the clubface, both perpendicular to the clubface of a traditional shaped clubhead. [0015]
  • Other objects, advantages and salient features of the invention will become apparent from the following detailed description, which taken in conjunction with the annexed drawings, discloses a preferred, but non-limiting, embodiment of the subject invention. [0016]
