How the Cantilevered Umbrella Works

We often see these oversized umbrellas alongside swimming pools or in open patios. They are used to act as shelter against rain or sunlight. A cantilever umbrella is characterized by a folding canopy which is mounted on a cantilevered umbrella stand. It brings elegance and shade to areas exposed to the bright sunlight. Adding one to a pool or backyard will be the ultimate in style.
A stand frame for an umbrella will include a shaft, an umbrella frame, and a foldable hanger arm hanging the umbrella frame. It also has a height-adjustable device, and an angle-adjusting device. The stand frame for an umbrella utilizes these devices to control the expansion or contraction and angular orientation of the umbrella frame. 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.
