发明名称 Collapsible golf fairway distance marker
摘要 A collapsible golf fairway distance marker including a visible structure that can assume two discrete configurations, and an anchor structure. The visible structure is generally cone-shaped when raised and flat when collapsed and is comprised of a base support ring, a spring-loaded plunger assembly disposed in the center thereof, and a plurality of generally trapezoidal shaped leaves. Each leaf has its narrower end captured within an annular recess formed between the plunger top and a cap screwed into the plunger, while its wider end is captured within an annular recess formed in the base support ring. Numerals indicating distance are affixed to or embossed in an upper part of one or more leaves. The anchor structure is connected to the base support ring and is buried beneath the ground to provide a fixed location for the visible structure on the fairway.
