ABSTRACT:
A portable shade unit particularly adapted for ready assembly into a free standing configuration may be assembled from a kit of prepackaged components. These components include a weightable base formed with an inner space for ballast such as water or sand. On a top wall of the base are sets of clips to hold an adjustable standard, a tiltable knuckle connector, and a commercially available hand-held umbrella such as a golf umbrella. For assembly a lower end of an outer tube of the standard is fitted in a bushing on the base. An upper end of an inner member of the standard then is placed into a lower sleeve of the knuckle connector. Lastly, a handle end of the umbrella is fitted into an upper sleeve of the connector. A canopy of the umbrella then may be opened to provide shade or other protection from weather as required. Further, an angular position of the umbrella may be adjusted by releasing a pivot connection of the knuckle connector.
