Abstract

Abstract In a set of golf clubs of the type commonly referred to as irons, where the loft of each club is unique and is indicated by indicia on the club head, first and second surfaces are provided on a backside of the club head such that those surfaces slope away from the striking face of the club head, and toward each other to form a ridge disposed about a rounded corner from the sole to the toe of the head. The ridge extends further away from the striking face at the center of the rounded corner than any other portion of the backside of the club head so that one surface may be easily viewed by a person holding the club by the shaft with the shaft extending away from him. The other surface may be easily viewed from a generally opposite direction. An indicia is placed on at least the one of the two surfaces to indicate the loft of the club head.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 314 words
A set of at least two golf clubs, each golf club being comprised of a head having a toe and a heel, said heel being connected to a shaft, said head having a striking face between said toe and heel with a rounded lower corner at said toe, and a sole extending from said heel to said toe around said rounded corner at said toe, said striking face extending upwardly from said sole between said toe and heel at a unique and acute loft angle, and said head having a backside between said toe and heel extending upwardly from said sole, a portion of said backside having first and second surfaces sloping away from said striking face and toward each other to form a ridge about said rounded corner from a point near the bottom of said rounded corner and adjacent said sole to a point near the top of said rounded corner and adjacent said toe, said ridge extending further away from said striking face at the center of said rounded corner than any other portion of said backside, said first surface being of such sloping configuration and of such rearward extent, and with the club head being so configured, that said first surface may be seen by a person holding said club at the end thereof remote from said head and viewing said golf club head along a line substantially parallel to said shaft, said second surface being connected to said sole and being of such sloping configuration relative to the configurations of said first surface, said sole, and said club head that said second surface may be viewed by a person facing said club head from a direction generally opposite to the direction said shaft extends from said head, and indicia on at least said one of said first and second surfaces indicative of the magnitude of said unique loft angle.
Claim 2
Dependent Claim 314 words
A set of at least two golf clubs, each golf club being comprised of a head having a toe and a heel, said heel being connected to a shaft, said head having a striking face between said toe and heel with a rounded lower corner at said toe, and a sole extending from said heel to said toe around said rounded corner at said toe, said striking face extending upwardly from said sole between said toe and heel at a unique and acute loft angle, and said head having a backside between said toe and heel extending upwardly from said sole, a portion of said backside having first and second surfaces sloping away from said striking face and toward each other to form a ridge about said rounded corner from a point near the bottom of said rounded corner and adjacent said sole to a point near the top of said rounded corner and adjacent said toe, said ridge extending further away from said striking face at the center of said rounded corner than any other portion of said backside, said first surface being of such sloping configuration and of such rearward extent, and with the club head being so configured, that said first surface may be seen by a person holding said club at the end thereof remote from said head and viewing said golf club head along a line substantially parallel to said shaft, said second surface being connected to said sole and being of such sloping configuration relative to the configurations of said first surface, said sole, and said club head that said second surface may be viewed by a person facing said club head from a direction generally opposite to the direction said shaft extends from said head, and indicia on at least said one of said first and second surfaces indicative of the magnitude of said unique loft angle.
Claim 3
Dependent Claim 11 words
The combination of claim 1 wherein said first surface is flat.
Claim 4
Dependent Claim 11 words
The combination of claim 1 wherein said first surface is concave.
Claim 5
Dependent Claim 30 words
The combination of claim 2 wherein said second surface is convex with a curvature generally conforming to said rounded corner of said club head between said sole and said toe.
Claim 6
Dependent Claim 30 words
The combination of claim 3 wherein said second surface is convex with a curvature generally conforming to said rounded corner of said club head between said sole and said toe.
