Abstract
Abstract An indicator device to inform golfers of the position of the cup on the green and other play aspects of a hole of a golf course. It has a display panel carrying a graphic representation of the hole including the tee and green, a grid of electrically energizable indicators associated with the green representation, an array of electrically energizable indicators associated with the tee representation and electrical circuitry for energizing predetermined indicators in the grid and the array.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
169 words
A golf course play indicator device comprising: a display panel which carries a graphic representation of the layout of a hole of a golf course including the tee and the green comprising a cup, a grid of a multiplicity of electrically energizable indicators arranged in vertical and horizontal rows within said representation of said green, an array of a multiplicity of electrically energizable indicators arranged in two spaced apart rows within said representation of said tee, an electrically energizable and changeable digital display unit to indicate the distance from the tee to said cup on said green, electrical circuit means comprising first switch means to selectively energize one of said indicators of said grid to indicate said cup position on said green and second switch means to energize one indicator in each of said two rows in said array to indicate a tee-off line on said tee, and means to automatically change said digital display of distance in response to changes made to said first and second switch means.
Claim 2
Dependent Claim
169 words
A golf course play indicator device comprising: a display panel which carries a graphic representation of the layout of a hole of a golf course including the tee and the green comprising a cup, a grid of a multiplicity of electrically energizable indicators arranged in vertical and horizontal rows within said representation of said green, an array of a multiplicity of electrically energizable indicators arranged in two spaced apart rows within said representation of said tee, an electrically energizable and changeable digital display unit to indicate the distance from the tee to said cup on said green, electrical circuit means comprising first switch means to selectively energize one of said indicators of said grid to indicate said cup position on said green and second switch means to energize one indicator in each of said two rows in said array to indicate a tee-off line on said tee, and means to automatically change said digital display of distance in response to changes made to said first and second switch means.
Claim 3
Dependent Claim
35 words
The indicator device of claim 1 wherein said first switch means has a first selector designating positions in vertical rows of said grid and a second selector designating positions in horizontal rows of said grid.
Claim 4
Dependent Claim
62 words
The indicator device of claim 1 that comprises in addition a second electrically energizable and changeable digital display unit to indicate the distance from said cup on said green to a pre-selected radius distance marker on said course layout and means to automatically change said second digital display of distance in response to changes made to said first and second switch means.
Claim 5
Dependent Claim
15 words
The indicator device of claim 3 wherein said distance marker is a 150 yard marker.
Claim 6
Dependent Claim
39 words
The indicator device of claim 1 having a time delay switch accessible to golfers playing said hole of said golf course to activate said electrical circuit means for a predetermined time interval and then automatically deactivate said circuit means.
Claim 7
Dependent Claim
20 words
The indicator device of claim 1 having lock means that prevents unauthorized adjustment of said first and second switch means.
Claim 8
Dependent Claim
20 words
The indicator device of claim 1 that includes a battery pack to supply electrical energy to said electrical circuit means.
Claim 9
Dependent Claim
20 words
The indicator device of claim 1 that includes a photovoltaic unit to supply electrical energy to said electrical circuit means.
Claim 10
Dependent Claim
29 words
The indicator device of claim 1 that is contained in a weatherproof case carried upon a locking post mount and there is a transparent plate covering said display panel.
Claim 11
Dependent Claim
29 words
The indicator device of claim 1 wherein said grid indicators and array indicators are illuminators positioned behind said panel and viewable through transparent portions of the panel when energized.
Claim 12
Dependent Claim
44 words
The indicator device of claim 1 wherein said grid indicators and array indicators are liquid crystal display elements that are visible as a part of the respective green representation and tee representation to a viewer of said device only when said indicators are energized.
Claim 13
Dependent Claim
65 words
The golf course play indicator device of claim 1 wherein said energizable indicators are liquid crystal displays and said device includes a liquid crystal display element to indicate the distance from tee to cup of the hole displayed on said device and another liquid crystal display element to indicate the actual 150 yard marker to pin distance dependent upon the pin placement on said tee.
Claim 14
Independent Claim
202 words
A method of informing golfers of vital play aspects of a hole of a golf course substantially immediately prior to the golfer's beginning of play of said hole which comprises: providing adjacent the tee of said hole a display panel which carries a graphic representation of the layout of said hole of the golf course including the tee and the green, providing in the green portion of said display panel a plurality of first electrically energizable indicators spaced apart that serve upon being energized to show the position of the cup upon said green at the time of said play, energizing one of said first indicators to show said cup position, providing in the tee portion of said display panel a plurality of second electrically energizable indicators spaced apart that serve upon being energized to show a tee-off position on said tee at the line of play, energizing a pair of said indicators to show said tee-off position, providing on the panel an electrically energizable and changeable digital display unit to indicate the distance from the tee to said cup on said green, and automatically controlling said digital display of distance by changes in said energizing of said first and second indicators.
Claim 15

A method of informing golfers of vital play aspects of a hole of a golf course substantially immediately prior to the golfer's beginning of play of said hole which comprises: providing adjacent the tee of said hole a display panel which carries a graphic representation of the layout of said hole of the golf course including the tee and the green, providing in the green portion of said display panel a plurality of first electrically energizable indicators spaced apart that serve upon being energized to show the position of the cup upon said green at the time of said play, energizing one of said first indicators to show said cup position, providing in the tee portion of said display panel a plurality of second electrically energizable indicators spaced apart that serve upon being energized to show a tee-off position on said tee at the line of play, energizing a pair of said indicators to show said tee-off position, providing on the panel an electrically energizable and changeable digital display unit to indicate the distance from the tee to said cup on said green, and automatically controlling said digital display of distance by changes in said energizing of said first and second indicators.
Claim 16
Dependent Claim
61 words
The method of claim 13 that further comprises: providing on said panel a second electrically energizable and changeable digital display unit to indicate the distance from the cup on said green to a pre-selected radius distance marker on said course layout and automatically controlling said second digital display of distance by changes in said energizing of said first and second indicators.
