Outdoor used stand frame of an umbrella
First Claim
1. A stand frame for an umbrella comprising:
- a main shaft composed of an upper tube, a middle tube connected to the upper tube, a lower tube, and a connecting sleeve connecting the middle and the lower tubes;
a stand base substantially mounted on a lower end of the lower tube;
a top cover substantially mounted on an upper end of the upper tube;
a height-adjustable device substantially mounted on the lower tube;
a lower sleeve mounted on the upper tube and being capable of sliding thereon;
a long hanger arm pivotally mounted on the lower sleeve;
a short hanger arm with two ends respectively pivotally connected to the top cover and the long hanger arm;
a fixing support including an L-shaped base section, a rotational section, and a connecting section;
an axle passing through the rotational section and the connecting section;
the connecting section being connected to the long hanger arm;
an umbrella frame composed of an upper hinge disk, a lower hinge disk, a multi-sectional telescopic tube having two ends the upper hinge disk and the lower hinge disk being respectively mounted at, a plurality of main ribs each pivotally connected to the upper hinge disk and a plurality of connecting ribs each with one end pivotally connected to the lower hinge disk and with the other end connected to a main rib;
an umbrella-opening string with one end tied to the top cover, passing around a pulley atop the umbrella frame, through a connecting column, and into the multi-sectional telescopic tube, and with the other tied to the lower hinge disk;
an upper-tube-pulling string partially wound around a windlass in the height-adjustable device on the lower tube, passing around a pulley at an upper end of the middle tube and below a lower end of the upper tube, and being tied at a bottom of the upper tube; and
a lower-sleeve-pulling string with one end tied to the lower sleeve, passing around a pulley atop the upper tube and entering the upper tube, and with the other tied at a top of the middle tube;
a vertical movement of the upper tube driving a corresponding vertical movement of the lower hinge disk by the lower-sleeve-pulling string, causing the long hanger arm to extend of to contract, which makes the umbrella-opening string to open or to close the umbrella frame.

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.

9. A stand frame for an umbrella comprising:
-
a main shaft including an upper tube, a middle tube connected to the upper tube, a lower tube, and a connecting sleeve connecting the middle and the lower tubes;
a stand base substantially mounted on a lower end of the lower tube;
a top cover substantially mounted on an upper end of the upper tube;
an angle-adjusting device mounted at the bottom of the upper tube;
a lower sleeve mounted on a section of the upper tube between the top cover and angle-adjusting device;
a long hanger arm pivotally mounted on the lower sleeve;
a short hanger arm with two ends respectively pivotally connected to the top cover and the long hanger arm;
a fixing support mounted at an end of the long hanger arm and including an L-shaped base section, a rotational section, and a connecting section;
