Abstract
A skeleton for umbrella tent mainly includes a top hub to which multiple brace poles are radially and pivotally connected to stretch by a predetermined angle; a bottom hub to which multiple stretch arms are radially and pivotally connected to stretch by a predetermined angle, and outer ends of these stretch arms are separately pivotally connected to a predetermined point on the brace poles; a flexible telescopic portion located between the top and the bottom hubs and consisting of multiple sections in the form of hollow truncated cones; and a pull rope extending through the telescopic portion with an upper end fixed to the top hub and a lower end hanging from the bottom hub to connect to a ring handle. By pulling the pull rope downward, the telescopic portion is folded to easily cause the stretch arms and the brace poles to move into a stretched position to set up the tent.
