Patent ID: 8161913

Claim:
A hound walker system for exercising a dog and a wide variety of other animals in a relatively restricted space, the system comprising, in combination: a spherical chamber formed of a male hemisphere and a female hemisphere, the male hemisphere having a circular edge with forked male circular edge projections, the female hemisphere having a circular edge with circular edge recesses adapted to removably receive the circular edge projections for forming the spherical chamber, the spherical chamber being fabricated of a strong wire mesh which is rubberized on all sides for durability, traction and for viewing into the spherical chamber; a generally rectangular opening in the male hemisphere, the opening having a height constituting about 33 percent of the diameter of the male hemisphere and a width constituting about 25 percent of the diameter of the male hemisphere, a generally rectangular door slidable between a closed position covering the opening and an open position laterally spaced from the opening, the door having a generally linear edge with door projections, the opening having a generally linear edge with door recesses adapted to removably receive the door projections for securing the door in a closed position; a base having a circular top and a circular bottom and a frusto-conical side wall, the top having a diameter less than the diameter of the spherical chamber, the bottom having a diameter greater than the diameter of the spherical chamber, the top being in a concave configuration with a radius of curvature essentially equal to the radius of curvature of the spherical chamber, the top having a plurality of apertures with a spherical ball extending upwardly and partially through an associated one of the apertures, a coil spring urging an associated one of the plurality of balls upwardly through an associated one of the apertures to form a recipient surface for receiving and rotatably supporting the spherical chamber whereby a dog within the spherical chamber may run and walk in place for exercise in a relatively restricted space; wheels coupled to the side wall of the base; and a handle on the side wall of the base diametrically opposite from the wheels for facilitating the moving of the base with respect to a floor.
