Golf Clubs

Abstract

Golf clubs having improved features and a golf swing training device are disclosed. In one embodiment, the golf club has a club head made of at least one material having a first specific gravity, and at least one weighting portion that has a higher specific gravity than the first specific gravity of the material forming the main body of the club head. In another embodiment, the golf club has a club head of the “iron” type, and the club head has a sole that is provided with “bounce” thereon. In another embodiment, the golf club has a club head of the “iron” type that has a configuration that provides it with improved ability to cut through the “rough” on the golf course. In another embodiment, the golf club has a club head having a club face with at least one portion thereof that has a thickness that is modified to account for a groove in the striking surface of the club face. In another embodiment, correlated golf clubs are provided in which the club face is opened or closed relative to at least one other club within a set of golf clubs. The golf swing training device has a structure that is attached to the golf club and extends outward from the front of the golf club that makes the rotation of the golf club shaft and/or club face more visible to the golfer.

1 . An iron type golf club head comprising a club face, a back surface on the opposite side of said club head from the club face, a top portion, a bottom, a toe, a heel, and a sole extending generally between the heel and the toe along the bottom of the club head, wherein the toe comprises an upper portion adjacent the top of the club head, and a lower portion adjacent the sole of the club head, and said club head comprises:
 a first extension of said iron type club head extending laterally outward from a lower portion of the toe of said club head, wherein said first extension extends laterally outwardly from the lower portion of said toe so that at least part of the first extension extends laterally outward beyond the upper portion of the toe of said club head; and   a weighting portion having a higher specific gravity joined to at least a portion of said first extension.   
     
     
         2 . The golf club head of  claim 1  further comprising:
 a second extension of said club head extending laterally outward from a lower portion of the heel of said club head; and 
 a weighting portion having a higher specific gravity joined to at least a portion of said second extension. 
 
     
     
         3 . The golf club head of  claim 1  wherein said sole has a lowest portion, and said first extension comprises a lowermost portion, and said lowermost portion of said first extension is disposed above the lowest portion of the sole of said club head. 
     
     
         4 . The golf club head of  claim 1  wherein first extension provides a portion of the toe of the club head with a concave configuration when the club head is viewed from the front. 
     
     
         5 . The golf club head of  claim 1  wherein the sole of said club head comprises a portion of the sole disposed below the geometric center of the club face, and said sole defines a surface, wherein there is a recess in the bottom of the club head that is located between the first extension and the portion of the sole disposed below the geometric center of the club face, wherein said recess extends upwardly in the bottom of the club head, and the recess has a forwardmost portion that is disposed rearwardly of the club face. 
     
     
         6 . The golf club head of  claim 2  wherein the sole of said club head comprises a portion of the sole disposed below the geometric center of the club face, and said sole defines a surface, wherein there is a recess in the bottom of the club head that is located between the second extension and the portion of the sole disposed below the geometric center of the club face, wherein said recess extends upwardly in the bottom of the club head, and the recess has a forwardmost portion that is disposed rearwardly of the club face. 
     
     
         7 . An iron type golf club head comprising a main body comprising a club face, a back surface on the opposite side of said club head from the club face, a top, a bottom, a toe, a heel, and a sole extending generally between the heel and the toe along the bottom of the club head, wherein said club head comprises:
 a lower portion extending upward from the sole of said club head, said lower portion comprising a portion of said toe and said sole, wherein part of said lower portion at the toe of said club head has a concave configuration when viewed from the front of said club head.   
     
     
         8 . The golf club head of  claim 7  wherein said lower portion of said club head further comprises a portion of said heel, and part of said lower portion at the heel of said club head also has a concave configuration when viewed from the front of said club head. 
     
     
         9 . The golf club head of  claim 7  wherein the main body comprises a material having a first specific gravity, said club head and said part of said lower portion with said concave configuration being formed by peripheral portions of said main body, wherein said club head further comprises a higher specific gravity weighting portion is joined to said main body and is disposed at least partially inward of the part of said lower portion with said concave configuration.
