Abstract
A circular or bar-type slide rule made of a durable rigid material for converting a golf handicap index into a converted playing handicap based upon the slope rating of a golf course. A method for calculating a converted playing handicap by aligning the player's handicap index value on a first logarithmic scale, locating the golf course slope rate on a second logarithmic scale so that the aligned value of the converted playing handicap may be read on the first scale.
Claims14
A converter for calculating golf handicaps dependent on a known handicap value and a known golf course slope rating, comprising:
- at least two substantially planar members;
- a first fixed logarithmic scale having values from 3 to 60 demarcated on a first of said at least two planar members, said first fixed logarithmic scale corresponding to a golf handicap value;
- a second fixed logarithmic scale having values from 50 to 150 demarcated on a second of said at least two planar members, said second fixed logarithmic scale corresponding to a golf course slope rating value;
- an alignment indicia positioned at a value of 113 on said second fixed logarithmic scale;
- and
- means for movable cooperation of said at least two planar members relative to each other, whereby said second planar member having said alignment indicia is movable to position said alignment indicia in juxtaposition to a point on the first fixed logarithmic scale demarcated on the first planar member.
A converter for calculating golf handicaps dependent on a known handicap value and a known golf course slope rating, comprising:
- a backing member, having an interior surface, an exterior surface, a plurality of edges defining a perimeter, a circular cut-away formed along an edge of said backing member, a first logarithmic scale corresponding to a golf course slope rating value in the range of 50 to 150, said first logarithmic scale further comprises an alignment indicia located about value 113, said first logarithmic scale being positioned on an upper surface of said backing member and an aperture passing through said back cover member for passage of a strap;
- a face member having an interior surface, an exterior surface, a plurality of edges defining a perimeter, a pin projecting from the interior surface of said face member, a circular cut-away formed along an edge of said face member and an aperture passing through said face member in alignment with said aperture passing through said backing member for passage of a strap;
- a circular disc member rotatably engaged on said pin projecting from the interior surface of said face member, said circular disc member having a second logarithmic scale positioned on an upper surface, said second logarithmic scale corresponding a golf handicap value in the range of 3 to 60;
- fastening means for fastening said back cover member to said face member.
A converter for calculating golf handicaps dependent on a known handicap value and a known golf course slope rating, comprising:
- a circular base member having a radial dimension, a top surface, a bottom surface, a centering pin protruding from said top surface, and an aperture passing through said base for passage of a strap;
- a circular disc member having a radial dimension less than said radial dimension of said base member, and an aperture through said disc for receipt of said centering pin said circular disc member being freely rotatable about said centering pin;
- a first fixed logarithmic scale positioned on the top surface of said circular disc member, said first fixed logarithmic scale corresponding to a golf course rating value in the range of 50 to 150 and further comprising an alignment indicia located about value 113;
- a second fixed logarithmic scale positioned on the top surface of said circular base member and visible relative to said first fixed logarithmic scale of said circular disc member, said second fixed logarithmic scale corresponding to a golf handicap value in the range of 3 to 60.
A converter for calculating golf handicaps dependent on a known handicap value and a known golf course slope rating, comprising;
- a rectangular slide cover forming an enclosed case, having upper and lower planar surfaces, at least one of the upper or lower planar surfaces of said slide cover, having at least one substantially rectangular aperture formed on said at least one planar surface;
- a rectangular slide member insertable in sliding engagement within said slide cover;
- a first fixed logarithmic scale positioned in at least one portion accurately about said at least one aperture formed on said at least one planar surface of the slide cover, said first fixed logarithmic scale corresponding to a golf course slope rating value in the range of 50 to 150 and further comprising an alignment indicia located about value 113;
- a second fixed logarithmic scale positioned on said slide member in alignment with said first logarithmic scale when said slide member is inserted within said slide cover, said second fixed logarithmic scale corresponding to a golf handicap value in the range of 3 to 60.
