ABSTRACT:
An improved personal shelter canopy hub is formed using a number of spherical rotating joint elements captured in a hub body. The joint elements provide rotational movement of canopy frame elements to allow easy opening and collapsing of a canopy frame and cover. An improved canopy includes two hubs joined by a cross shaft. Each hub may be formed by molding in high-density plastic and combined with stub arms to facilitate subsequent assembly of a completed canopy.
