ABSTRACT:
A portable seat for hunters consisting of a vertical body to be placed on a tree trunk and held at the desired height by a chain having one end attached to one side of the body so that the other end may be wrapped around the tree and then removably attached to the other side of the body. A seat is hinged to the top of the body so that it can be folded into a closed position forming a flat package with all parts contained therein. When the seat is swung into open position it extends outwardly from the body into a horizontal position. A rigid non-extensible member is hinged to the underside of the seat so that it can be moved into a diagonal position with its free end engaging an abutment on the vertical body to form a strut or brace for the seat. The length of the brace and the location of the hinge are selected so that the brace is wholly within the package when the seat is moved to closed position and a spring bias is provided to keep the free end of the brace always in contact with the body. Means is provided on the back of the body forming clips for fastening to a belt.
