Abstract
This invention is related to an improved adjustable support for an umbrella which consists of a fixing seat and two flexible components. Along the fixing seat there is a longitudinal opening, and semi-ball protuberances are provided around the inner surface of the fixing seat. The opening and the semi-ball protuberances are used to allow the fixing seat to be securely clamped on one side of the beach chair.

These two flexible components are used for angle adjustment of the umbrella in accordance with the direction of sunlight. It is, therefore, a simple structure, easy to use, and practical creation.
