1. A pole and base assembly comprising:
a pole with a diameter, wherein said pole includes an upper engagement portion protruding beyond said pole diameter and slidable along said pole, and said pole includes a lower engagement portion protruding beyond said pole diameter at a fixed height on said pole, wherein said upper engagement portion is biased toward said lower engagement portion; a base with a top surface wherein said base includes a socket to receive said diameter of said pole, a channel to allow said lower engagement portion of said pole to pass through said base when said pole is placed through said socket, and a locking portion; wherein said base engages said upper engagement portion and prevents said upper engagement portion from passing through said base when said pole is placed through said socket; wherein sliding movement of said upper engagement portion by urging said pole through said socket against said biasing force allows said pole to pass through said socket a sufficient distance to reach a point of clearance between said lower engagement portion and said socket; and, wherein said locking portion is adapted to receive said lower engagement portion, enabling said upper and lower engagement portions to clamp said base between them when the force against the biasing force is released, locking said pole to said base. |
