Weighted iron set

Abstract

The present invention is direct to a set of golf clubs comprising long irons, mid-irons and short irons. The invention contemplates the use of titanium or steel for the main body portion and significant tungsten weight members at the heel and toe.

1 . A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees, a second club head having a loft of between about 26 and 35 degrees, and a third club head having a loft of about 36 degrees or greater, wherein:
 the first, second and third club heads each comprise a heel, a toe, a topline, a sole, a hosel and a front face having a face center, each club head having a club head mass that is different than the previous club head by at least 5 grams, and wherein at least one of the club heads includes a tungsten heel member and a tungsten toe member that together comprise more that 50% of the club head mass.   
     
     
         2 . The set of golf clubs of  claim 1 , wherein the first and second club heads each have a tungsten heel member and a tungsten toe member, wherein the tungsten heel member plus the tungsten toe member weigh 135 grams or greater. 
     
     
         3 . The set of golf clubs of  claim 1 , wherein the first and second club heads are comprised of titanium and tungsten and the tungsten portion forms greater than 25% of the club heads' volume. 
     
     
         4 . The set of golf clubs of  claim 2 , wherein the third club is comprised of titanium and a steel portion and the steel portion comprises between 50% and 70% of the club head mass. 
     
     
         5 . A set of golf clubs comprising at least a first club head having a loft between about 15 and 25 degrees, a second club head having a loft of between about 26 and 35 degrees, and a third club head having a loft of about 36 degrees or greater, wherein:
 the first, second and third club heads each comprise a solid volume, a heel, a toe, a topline, a sole, a hosel and a front face having a face center, wherein at least one of the club heads has an overall club head mass and is comprised of a steel body member and a steel face insert that together comprise less than 75 percent of the overall club head mass and is further comprised of a tungsten heel member and a tungsten toe member that together comprise more that 25% of the club head mass.   
     
     
         6 . The set of golf clubs of  claim 5 , wherein the first and second club heads each comprise a steel body member and a steel face insert and have a tungsten heel member and a tungsten toe member, wherein the tungsten heel member plus the tungsten toe member weigh 70 grams or greater. 
     
     
         7 . The set of golf clubs of  claim 5 , wherein the first and second club heads are comprised of a steel portion and a tungsten portion and the tungsten portion forms at least about 20 percent of the club heads' solid volume. 
     
     
         8 . The set of golf clubs of  claim 7 , wherein the third club is comprised of a steel portion and a tungsten portion and the tungsten portion comprises at least about 20 percent of the club head mass. 
     
     
         9 . A set of golf clubs comprising at least a first golf club, a second golf club, and a third golf club, wherein:
 the first, second and third golf clubs are each comprising a heel, a toe, an upper surface, a lower surface, a hosel and a front face having a face center, and   the first golf club further comprising a first loft angle (LA 1 ) of between 15 and 25 degrees and a first blade length, a first hosel length and a first scoreline width,   the second golf club comprising a second loft angle (LA 2 ) of between 26 and 35 degrees and a second blade length, a second hosel length and a second scoreline width, and   the third golf club comprising a third loft angle (LA 3 ) of 36 degrees or greater and a third blade length, a third hosel length and a third scoreline width,   wherein the first, second and third blade lengths are approximately constant and the second hosel length is greater than the first hosel length and the third hosel length is greater than the second hosel length; and   wherein the second scoreline width is less than the first scoreline width and the third scoreline width is less than the second scoreline width.   
     
     
         10 . The set of golf clubs of  claim 9 , wherein the first golf club has a first toe height, the second golf club has a second toe height greater than the first toe height and the third golf club has a third toe height greater than the second toe height. 
     
     
         11 . The set of golf clubs of  claim 9 , wherein the first golf club has a first sole width, the second golf club has a second sole width less than the first sole width and the third golf club has a third sole width less than the second sole width. 
     
     
         12 . The set of golf clubs of  claim 9 , wherein the first golf club has a first tungsten toe member, the second golf club has a second tungsten toe member with greater mass than the first tungsten toe member and the third golf club has a third tungsten toe member with greater mass than the second tungsten toe member. 
     
     
         13 . The set of golf clubs of  claim 12 , wherein the first golf club has a first tungsten heel member, the second golf club has a second tungsten heel member with less mass than the first tungsten heel member.
