A pole shelf for mounting to a pole has a two-piece bracket and a two-piece shelf. The bracket is removably secured to poles of different diameters by adjusting a sliding engagement existing between pairs of male and female mating sleeves. The bracket pieces have a lip between upper and lower hub protrusion ribs and the lip has an outer cam edge with detents. The shelf pieces have a protrusion rib, an outer wall and a shelf bottom between the protrusion rib and outer wall, a retention post on the underneath side of the shelf bottom, a connector for releasably connecting ends of the two shelf pieces to each other and one or more shelf bottom connectors for releasably connecting the shelf bottoms to each other. When the shelf is in a closed state it is secured to the bracket, which itself is secured to a pole, by engaging the retention posts of shelf pieces with the outer cam edges of the bracket pieces and rotating the shelf so that the outer cam edges become removably locked into the retention posts. |
