  • Patent number: 4794718
    Abstract: An ice fishing assembly includes a conical ring member adapted for the insertion of a fishing pole having a spring-type signaling device. Two displaceably connected sections of transparent plastic resilient material normally enclose the top opening of the ring member and permit the extraction of fish during which the sections are automatically displaced. The plastic sections are interchangeable with styrofoam sections of the same size to further retard and prevent the passage of heat and air energy from the water to the atmosphere. A plurality of assemblies may be nested together and carried in a common receptacle with the fishing apparatus poles in the central cavity of the innermost ring member to be conveniently transported as a kit to allow the fishing of a plurality of ice holes.
