Abstract
Abstract A portable blind for a hunter, photographer, naturalist, or the like, comprising one or more frame assemblies with a flexible exterior covering. Each frame assembly includes upright legs which are joined at the upper end thereof by a frame member. The frame assemblies are fabricated from lightweight materials such as aluminum or plastic tubular members or inflatable members which may be easily transported to a desired site. A flexible exterior covering is connected to the frame assemblies and preferably includes one or more viewing ports. At a selected site the frame assembly or assemblies are set up and operably positioned to form a shell with a covering and viewing port in an upper portion of the blind.
