Abstract

Abstract An ice fishing device having a cylindrical sleeve that is resilient and radially compressible to enable the ice fishing device to adapt to a variety of different size holes in the ice and members on the cylindrical sleeve to vertically and securely support the ice fishing device within the confines of a hole in the ice. A small charcoal chamber attaches to the side of the ice fishing device and holds sufficient charcoal to produce sufficient heat to keep the water in the hole from freezing yet keep the ice fishing device sufficiently cool so as not to burn a fishing line located therein.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 224 words
An ice fishing device operable for fishing therethrough comprising: a cylindrical sleeve having a top and a bottom, said cylindrical sleeve having a pair of ends that overlap each other to define a cylindrical shape having an interior surface and an exterior surface, said cylindrical sleeve made from a resilient material so that radial compression of said cylindrical sleeve produces a force to restore said cylindrical sleeve to its original shape, said cylindrical sleeve having an unobstructed passage therethrough to permit one to pull a fish therethrough without displacing said cylindrical sleeve; ice gripping members located adjacent but spaced from the bottom of said cylindrical sleeve, said ice gripping members coacting with said cylindrical sleeve to permit a user to position the bottom of said ice fishing device in a hole in the ice; and a heat chamber attached to exterior surface of said cylindrical sleeve so that when said cylindrical device is positioned in the ice said heat chamber is remotely located from a fishing line to permit heat transfer from said heat chamber to said cylindrical sleeve to prevent freezing of water located in the hole in the ice, said heat chamber also acting as a source of heat for warming a user's hands, said heat chamber being disposed above the ice gripping members and intermediate the ends of the cylindrical sleeve.
