主权项 1. A stanchion comprising: a base; a pole including a hollow interior portion, wherein said pole extends upward from said base; a cap piece including a lower portion and an upper portion, wherein said lower portion extends inside said hollow pole; at least one linkage opening defined through said cap piece; a linkage member including a length, wherein said linkage member is threaded through said linkage opening so a portion of said linkage member is within said pole and a portion of said linkage member is outside of said pole; and, wherein said cap piece may be moved vertically within said pole between a raised position and a lowered position; wherein when said cap piece is in said raised position, a portion of said linkage opening that is unobstructed by said pole is sized so said length of said linkage member may be removed from or inserted into said interior portion of said pole through said linkage opening; and, wherein when said cap piece is in said lowered portion, the portion of said linkage opening unobstructed by said pole is sized to restrict movement of said linkage member.
