  • Portable, collapsible shelters
    Patent number: 7578307
    Abstract: A lightweight, deployable, portable shelter is described. The portable shelter may be a tent. The tent can be used indoors as well as outdoors. The structure of the portable shelter is determined by compression elements and tensile members such that the compression elements do not touch. The forces acting on each component of the structure are axially-loaded, thereby taking advantage of the characteristics of the compression elements and tensile members to provide a tent with improved strength.
