Abstract:
An umbrella stand may include a receptacle for receiving a portion of a mast of an umbrella and a base portion configured to interface with a ground surface. A movable joint is disposed between the receptacle and the base portion. A frictional force present between components of the movable joint is great enough to maintain a position of the receptacle relative to the base portion under the weight of the umbrella and mast, and is small enough that the receptacle can be repositioned relative to the base portion by application of a manual force to the mast of the umbrella. The movable joint may be lockable into different positions.
