Abstract
Abstract A tent or collapsible shelter of the umbrella tent-type. The tent includes, in one lightweight package, a foldable frame and a tent cover affixed to the frame. In one embodiment, the tent frame includes a vertical erecting rod located at the apex of the tent frame and flexible, segmented tent poles pivotably connected at the upper ends to a sleeve section which is, in turn, slidable on the erecting rod. The tent cover is attached to the tent poles near the ground, is slidably connected to an intermediate section of the tent poles and is connected at the top to the sleeve section at the base of the erecting rod. In this manner, the tent cover is tautly affixed to the tent frame in an erected position and is loosely affixed to the tent frame in a collapsed position. The sections of the segmented tent pole are connected to one another in the collapsed state and are elastically urged into an intercoupling engagement to form a rigid support upon erection.
