Abstract

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. At the fixing seat, it is also provided with a deep hole for the insertion of a umbrella central rod, and two flexible components are provided on each of the upper and lower parts of the umbrella central rod respectively. 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.
