ABSTRACT:
A shading device includes an abbreviated height umbrella having a articulating ball attachment structure on both its upper and lower sides and attached to a pivoting arm through a series of universal connectors and joints having spherical articulating balls secured in articulating ball joints with tension force provided by joint retention screws. The umbrella can be either supported from the bottom or suspended from the top, to provide maximum articulation. A tripod folding stand has a body having an upper ribbed member for engagement with the clamp, and a series of three legs pivotally attached at an upper portion of the body and struts attached at a lower portion between the legs and body. The ends of the legs have pivotal spikes which can be pivoted to an open direction and directed into dirt or sand or other material, or used as hold down extensions.
