Putters

Abstract

A set of putters, the different putters having different values of at least one of the variables which affect the suitability of the putter for short or long putts, for example loft, lie, length, coefficient of restitution of the impact face ( 22 ) and alignment aid ( 21 ).

1 . A set of putters, each of the putters having different values of at least one characteristic selected from loft, lie, length, coefficient of restitution and visual alignment aid. 
     
     
         2 . A set of putters according to  claim 1  wherein each of the putters has different values of each of the characteristics of loft, lie, length, coefficient of restitution and visual alignment aid. 
     
     
         3 . A set of putters according to  claim 1  wherein all the putters have the same value of at least one of the characteristics of loft, lie, length, coefficient of restitution and visual alignment aid. 
     
     
         4 . A set of putters according to  claim 1  wherein each of the putters has a loft which is different from the loft of each of the other putters. 
     
     
         5 . A set of putters according to  claim 1  wherein each of the putters has an impact face whose coefficient of restitution is different from the coefficient of restitution of the impact face of each of the other putters. 
     
     
         6 . A set of putters according to  claim 1  which consists of four, five, six, seven, eight or nine putters displayed for sale in a shop. 
     
     
         7 . A method of playing golf in which a golfer carries a set of putters, each of the puffers having different values of at least one characteristic selected from loft, lie, length, coefficient of restitution and visual alignment aid, selects one of the putters for each putt, and uses the selected putter to make the putt. 
     
     
         8 . A set of clubs which includes correlated woods, correlated irons and a set of putters as claimed in  claim 1 , the set consisting of two or three puffers. 
     
     
         9 . A method of selecting a set of putters as claimed in  claim 1  the set consisting of two or three putters, the method comprising experimenting with at least three putters from a set of putters as claimed in  claim 1  and selecting two or three putters for use. 
     
     
         10 . A set of putters according to  claim 1  wherein each of the putters has a different value of a characteristic selected from one or more of loft, visual alignment aid and coefficient of restitution, and all the putters have the same value of the other characteristics selected from loft, lie, length, coefficient of restitution and visual alignment aid. 
     
     
         11 . A set of putters according to  claim 10 , which consists of two or three putters. 
     
     
         12 . A set of putters, each of the putters having different values of at least one characteristic selected from loft, lie, length, coefficient of restitution and visual alignment aid; the loft of each of putter being from 1.5 to 6°; and the lie of each putter being from 55 to 90°; the length of each putter being from 32 to 39 inches. 
     
     
         13 . A set of putters according to  claim 12 , the set consisting of a first putter and a second putter; the first putter having a loft 4.0 to 5.5°, a lie of 70 to 90° and a length of 32 to 36 inches; and the second putter having a loft of 1.5 to 2.5°, a lie of 55 to 70° and the length of 36 to 39 inches. 
     
     
         14 . A set of putters according to  claim 13  wherein the first putter has a polymeric impact face, and the second putter has a coefficient of restitution, which is equal to the coefficient of restitution of the first putter plus 5-20%. 
     
     
         15 . A set of putters according to  claim 12 , the set consisting of a first putter and a second putter, and the first putter having a relatively strong alignment aid in the second putter having a relatively weak alignment aid. 
     
     
         16 . A set of putters according to  claim 12 , the set consisting of a first putter, a second putter and a third putter; the first putter having a loft 4.0 to 6.0°, a lie of 75 to 90and a length of 32 to 35 inches; the second putter having a loft of 2.5 to 4.5°, a lie of 65 to 75° and the length of 35 to 37 inches; and the third putter having a loft of 1.5 to 2.50, a lie of 55 to 65° and a length of 37 to 39 inches. 
     
     
         17 . A set of putters according to  claim 16  wherein the first putter has a polymeric impact face, the second putter has a polymeric impact face and third putter has a metallic impact face.
