Abstract
Abstract A golf club has an offset shank between its shaft and its head. The offset shank has an arcuate reinforcing rib interconnecting intermediate and lower legs of the shank and extending to the head. This prevents the various legs of the shank from bending. The shaft is inclined rearwardly at a small angle to position the handle or grip above the head while the shaft is aligned with a golf ball when at rest.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
216 words
A golf club comprising: a head having a frontal striking surface, a top surface, a bottom surface, a rear surface, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top surface of the head and extending perpendicularly therefrom; the intermediate leg extending forwardly of the striking surface a distance which is at least a fraction of the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg and inclined toward the heel portion at an acute angle from a plane defined by the other two legs; a reinforcing rib interconnecting the lower and intermediate legs and extending substantially the entire length of each of said legs; and the outer extremity of the rib defining a concave, arcuate edge, the lower end of which is contiguous with the frontal striking surface; an elongate shaft generally coextensive with said outer leg and having one end connected to the outer leg and a grip at its other end; and said outer leg and said elongate shaft being arranged at an angle slightly less than 90° to the intermediate leg so that the center of the grip is substantially in line with the lower leg.
Claim 2
Dependent Claim
216 words
A golf club comprising: a head having a frontal striking surface, a top surface, a bottom surface, a rear surface, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top surface of the head and extending perpendicularly therefrom; the intermediate leg extending forwardly of the striking surface a distance which is at least a fraction of the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg and inclined toward the heel portion at an acute angle from a plane defined by the other two legs; a reinforcing rib interconnecting the lower and intermediate legs and extending substantially the entire length of each of said legs; and the outer extremity of the rib defining a concave, arcuate edge, the lower end of which is contiguous with the frontal striking surface; an elongate shaft generally coextensive with said outer leg and having one end connected to the outer leg and a grip at its other end; and said outer leg and said elongate shaft being arranged at an angle slightly less than 90° to the intermediate leg so that the center of the grip is substantially in line with the lower leg.
Claim 3
Dependent Claim
102 words
A golf club according to claim 1 wherein the head is a putter head; the lower leg is connected to the top surface of the putter head at about one-quarter of the distance from the heel portion to the toe portion; the striking surface has a heigth which is greater than the radius of a golf ball, but less than the diameter thereof; and the lower portion of the arcuate edge of the rib extends rearwardly of the striking surface at least a distance equal to the difference between the diameter of the golf ball and the heigth of the striking surface.
Claim 4
Dependent Claim
64 words
A golf club according to claim 2 wherein the arcuate edge is a segment of a circle having a radius generally equal to the distance from the top surface of the head to the underside of the intermediate leg, and a center at a level above the top surface to thereby dispose the lower portion of the arcuate edge rearwardly of the striking surface.
Claim 5
Dependent Claim
183 words
A golf club comprising: a head having a frontal striking surface, a top, a bottom, a rear, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top of the head and extending upwardly therefrom; the intermediate leg extending forwardly from the upper end of the lower leg and forwardly of the striking surface a distance which approaches the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg; an elongate shaft having one end connected to the outer leg and having a grip at its other end; the shaft and outer leg being coextensive and inclined toward the heel portion at an obtuse angle to the top of the head and also inclined at a small angle toward the lower leg so that the center of the grip is substantially in line with the lower leg; and rib means interconnecting the lower and intermediate legs for reinforcing the same extending normal to said striking surface and forwardly thereof.
Claim 6
Dependent Claim
183 words
A golf club comprising: a head having a frontal striking surface, a top, a bottom, a rear, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top of the head and extending upwardly therefrom; the intermediate leg extending forwardly from the upper end of the lower leg and forwardly of the striking surface a distance which approaches the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg; an elongate shaft having one end connected to the outer leg and having a grip at its other end; the shaft and outer leg being coextensive and inclined toward the heel portion at an obtuse angle to the top of the head and also inclined at a small angle toward the lower leg so that the center of the grip is substantially in line with the lower leg; and rib means interconnecting the lower and intermediate legs for reinforcing the same extending normal to said striking surface and forwardly thereof.
Claim 7
Dependent Claim
15 words
A golf club according to claim 4 wherein said small angle is less than 5°.
Claim 8
Dependent Claim
41 words
A golf club according to claim 4 wherein the head is a putter head, the intermediate leg extends forwardly of the striking surface a distance less than the radius of a golf ball, and said small angle is less than 20°.
Claim 9
Dependent Claim
184 words
A golf club comprising: a head having a frontal striking surface, a top surface, a bottom surface, a rear surface, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top surface of the head and extending upwardly therefrom; the intermediate leg extending forwardly from the upper end of the lower leg and forwardly of the striking surface a distance which approaches the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg; a reinforcing rib interconnecting the lower and intermediate legs and extending substantially the entire length of each of said legs; an elongate shaft having one end connected to the outer leg and having a grip at its other end; and the shaft and outer leg being coextensive and inclined toward the heel portion at an obtuse angle to the top surface and also inclined at a small angle toward the rear surface so that the center of the grip is substantially in line with the lower leg.
Claim 10
Dependent Claim
184 words
A golf club comprising: a head having a frontal striking surface, a top surface, a bottom surface, a rear surface, and toe and heel portions; an offset shank including a lower leg, an intermediate leg and an outer leg; the lower leg being connected to the top surface of the head and extending upwardly therefrom; the intermediate leg extending forwardly from the upper end of the lower leg and forwardly of the striking surface a distance which approaches the radius of a golf ball; the outer leg extending upwardly from the outer end of the intermediate leg; a reinforcing rib interconnecting the lower and intermediate legs and extending substantially the entire length of each of said legs; an elongate shaft having one end connected to the outer leg and having a grip at its other end; and the shaft and outer leg being coextensive and inclined toward the heel portion at an obtuse angle to the top surface and also inclined at a small angle toward the rear surface so that the center of the grip is substantially in line with the lower leg.
