Abstract
Abstract A collapsible shelter of the umbrella-tent type including a foldable frame and a cover of sheet material affixed to the frame, wherein the frame is provided with ground-engaging foot members which firmly secure the bottom and/or floor of the tent to the base of the frame. The tent frame comprises a plurality of support members which, when the shelter is erected, extend outwardly and downwardly from the hub to the ground. The novel foot members comprise a central body attached to the downwardly extending end of the respective support members. An elongate base is connected integrally with the central body portion of the foot member, and an elongate opening is provided in the base for attachment of one end of a strip of webbing or fabric which is attached at its other end to the bottom and/or floor of the tent cover. Means are also provided for attaching and anchoring a tie-rope or cord to the foot member.
