ABSTRACT:
An umbrella includes a hollow tubular handle having an open end and an opposite closed end with an umbrella mounting aperture; a hub having a central section connected between an enlarged flange section with a dimension greater than the opening in the first end, and a cylindrical, reduced diameter shaft insertable within the umbrella mounting aperture; four ribs hingedly secured to the hub by living hinges to permit pivotal movement of the ribs only between an opened position in which the ribs are substantially positioned in a plane perpendicular to the shaft and a closed position in which the ribs are substantially coaxial with and adjacent to the shaft, the central section providing a limit on the pivotal movement of the ribs to prevent inversion thereof; a web of flexible, water-resistant material connected to the hub and the ribs; a key secured to the shaft; four key receiving slots in communication with the umbrella mounting aperture for matingly engaging with the key to permit locking of the hub to the handle when the shaft is inserted and rotated within the umbrella mounting aperture, whereby the closed end of the handle biases the ribs to the opened position; and the hub, ribs and web being insertable into the handle through the open end thereof so as to fit entirely within the handle with only the enlarged end of the hub protruding therefrom.
