Abstract

Abstract A portable personal shelter formed of a sheet of water-repellant canvas or fabric having a semi-circular edge provided with a gusset through which is disposed a bowed flexible rod. The ends of the rod projecting from the gusset are provided with a ring to which is removably attached the end of a chordal member in the form of an elastic band provided at each end with a hook for attachment to a ring. A rope is attached to the center of the straight chordal edge of the sheet for attachment to a tree trunk or to a vertical post, with the chordal member engaged with the surface of the tree trunk or vertical post, thus forming a semi-conical roof for protecting a person from rain or snow. For easy transportation, the elastic band is doubled-up by passing through a ring and attaching both hooks to the same opposite rings such as to decrease the chordal length. While in the transportation mode, the shelter can be carried on the head of a person to provide protection against rain or snow while walking.
