Abstract
A wedge type golf club head including a blade having a majority of its mass in an upper portion of the blade. The upper portion of the blade is weighted with a bulbous mass disposed at the rear of the blade, the bulbous mass decreasing in thickness towards a lower portion of the club from a region of greatest thickness and the bulbous mass being formed, in one embodiment, along a top surface of the club.
Description
- The invention relates to golf clubs and in particular to wedge type golf clubs.
- Wedge type golf clubs are adapted for making shots from sand, water or similar hazards which may exist on a golf course. Wedge heads of the prior art typically include thick metal blade sections behind a lower portion of the club, with the head steeply inclined to the club shaft. In U.S. Pat. No. 3,079,157, a majority of mass of a typical wedge is concentrated along a bottom margin of the wedge head blade. Typically, where the majority of mass of the wedge club is concentrated in a lower portion of the club, the golf ball tends to skip upon impact with the club.
- Although prior wedge head designs have been moderately successful, the ball skip on impact results in a loss of power and possibly direction. Therefore, it is an object of the present invention to provide a new and improved wedge type golf club that avoids ball skip.
- It is a further object of the present invention to provide a new and improved wedge type golf club which improves power transfer from club to ball that translates to improved loft and distance.
- The above objects have been met with a golf club head including a blade to be used as a wedge in combination with a hosel and a shaft, the blade concentrating a majority of its mass above a blade center. The mass is formed in an upper portion of the wedge blade and correspondingly, a lower portion of the wedge blade has relatively less mass than the upper portion. A center line divides the upper and lower portions. The upper portion of the blade is weighted with a rear bulbous mass decreasing in thickness towards the lower portion from a region greatest in thickness. The bulbous mass may be integral with the rear surface. In one example, the club head comprises a steel blade including a steel bulbous mass. The lower portion of the club head is a flat sheet.
- The blade has a rear surface, a front face including a golf ball striking region, a top surface, and upper and lower portions. The bulbous mass of the blade, in one embodiment, includes a pair of sloping surfaces joined at an edge therebetween. The first sloping surface extends along the top surface and away from the rear surface and the second sloping surface extends towards the rear surface. The second sloping surface and the rear surface are joined at a corner therebetween.
- Because at least some of the bulbous mass or the entire bulbous mass is located above the region at which a golf ball is to be struck, the loft and distance of a struck golf ball is improved. Further, a golfer has an improved and more solid “feel” when striking the golf ball.

FIG. 7 is a bottom view of the wedge type golf club head ofFIG. 1 . - With reference to
FIGS. 1, 3 , 4A and 4B, there is seen a wedge typegolf club head 10 of the present invention featuring ablade 12. Theblade 12 may comprise steel or any other desired material. Theblade 12, in combination with ahosel 14 and ashaft 18, received within a shaft-receivingaperture 16 of thehosel 14, or otherwise secured to the hosel, is to be used as a wedge. Theblade 12 extends outwardly from thehosel 14. Theclub head 10 comprises abulbous mass 20 disposed in anupper portion 22 of the club blade. The rear surface of theblade 26 includes thebulbous mass 20. Thebulbous mass 20 may be integral with therear surface 26 of theblade 12. Thebulbous mass 20 may comprise steel or any other desired material. Thebulbous mass 20 may also range in weight from about, for example, 45 to 85 grams. - With reference to
FIGS. 3, 4A and 4B, a center line C is depicted to show a division of the blade of theclub head 10 intoupper portion 22 andlower portion 24. The center line C extends across therear blade face 26 and is in vertical alignment with a line D dividing a length l of theclub blade 12 in half. Lines C and D approximate the described locations and are not necessarily to drawn scale. Thebulbous mass 20 decreases in thickness and mass towards thelower portion 24 from aregion 44 of greatest thickness. Thelower portion 24 of the blade has less mass than theupper portion 22 of the blade. In one embodiment, thelower portion 24 of the blade is a flat sheet 29 (FIG. 1 ) relatively uniform in thickness. - With reference to
FIGS. 4A, 4B , 5A and 5B, it is seen that the bulbous mass may be disposed in various areas of the upper portion of the blade. In one example (FIGS. 4A and 4B ), thebulbous mass 20 is disposed in anupper third 28 of theupper portion 22. In one embodiment (FIG. 5A ),bulbous mass 60 is disposed in an upper twothirds 48 ofupper portion 70 ofblade 65. Theupper portion 70 has a greater mass thanlower portion 72 of the blade. In another embodiment (FIG. 5B ),bulbous mass 62 is disposed in the entireupper portion 74 ofblade 67. In other words, thebulbous mass 62 extends from a lowermost region of theupper portion 74 to an upper most region of theupper portion 74. Theupper portion 74 has a greater mass thanlower portion 76 of the blade. The bulbous mass may be disposed in any other desired area of the upper portion. Features of theblade 12 are not necessarily drawn to scale. - In one example, as seen in
FIG. 6 , thebulbous mass 20 is integral with, and extends along, atop surface 32 of theblade 12. - Referring to
FIGS. 2, 4A and 4B, theblade 12 includes a frontstriking surface 30 opposed to the rear surface 26 (FIG. 3 ). The frontstriking surface 30 includes astriking region 36 which is a region anywhere on thestriking surface 30 where agolf ball 38 is to be struck. In one example, at least a portion of thebulbous mass 20 or the entirebulbous mass 20 is disposed above thestriking region 36. Therefore, the loft and distance of a struckgolf ball 38 is improved. Further, a golfer has an improved and more solid “feel” when striking thegolf ball 38. - With reference to
FIGS. 1, 4A and 4B, it is seen that thebulbous mass 20 of theblade 12 includes a pair of slopingsurfaces edge 44 therebetween. The firstsloping surface 40 extends along thetop surface 32 of theblade 12 and away from therear surface 26 and the second slopingsurface 42 extends towards therear surface 26. The secondsloping surface 42 and therear surface 26 are joined at acorner 46 therebetween. - With reference to
FIGS. 4A, 4B and 7, it is seen that thelower portion 24 of theblade 12 and aportion 50 of theupper portion 22 of theblade 12, not including thebulbous mass 20, are relatively less in thickness than the bulbous mass. The thickness ofportion 50 andlower portion 24 may be the same or different, if desired. In one example, theportion 50 of theblade 12 and thelower portion 24 are about ⅛th of an inch in thickness. The thickness may vary as desired. InFIG. 7 , it is seen that a sole 52 of the lower portion of theblade 12 has relatively less thickness than thebulbous mass 20.
