Abstract
An umbrella stand having an outer decorative surface is provided, for use with a large, outdoor-style umbrella. The outer surface of the stand is formed on an exterior shell that is fabricated out of a corrosion-resistant material, such as Aluminum. A weighted mass is attached to an inner surface of the exterior shell, thereby protecting the less corrosive-resistant material from the elements. Additionally, the weighted mass is attached to the exterior shell piece in a manner that none of the mass rests upon the surface on which the umbrella stand rests. In this manner, only the corrosion-resistant, decorative piece touches the support surface, preventing any discoloration that may occur upon the surface of the weighted mass from staining the area on which the umbrella stand rests—frequently a concrete surface.
