ABSTRACT:
A stand frame for an umbrella comprises a shaft, an umbrella frame, a foldable hanger arm hanging the umbrella frame, a height-adjustable device, and an angle-adjusting device. The stand frame for an umbrella utilizes the height-adjustable device and the angle-adjusting device to control the expansion/contraction and angular orientation of the umbrella frame thereof. The height-adjustable device provides a mechanism by which the middle section of the shaft can rotate horizontally, so as to move the umbrella frame about the shaft. A pull string extending from the shaft to the umbrella frame drives a vertical movement of the upper section of the shaft and the expansion of the umbrella frame simultaneously. A set of other pull strings are manipulated by the angle-adjusting device to vary the angular orientation of the umbrella frame in three dimensions.
