Abstract
A self-righting stick-type object holder for pets includes a set of fixed structure, that include a top shell and a bottom shell, ballast disposed in the bottom shell, and a collet disposed in the interior of the holder and having a plurality of collet jaws. The top and bottom shells are adjustably coupled to one another and define an interior of the holder. The bottom shell has an exterior having a spherical or semi-spherical profile to facilitate a smooth or relatively-smooth rolling function when the holder is placed upright on a flat surface. The fixed structures include tapered internal surfaces. The jaws have inward-facing contact surfaces that collectively define a central receptacle and outward-facing tapered surfaces that interact with the tapered internal surfaces. Adjusting the top and bottom shells forces the tapered internal surfaces against the outward-facing tapered surfaces of the collet jaws, thereby forcing the collet jaws together and reducing a diameter of the central receptacle such that a stick-type object may be retained therein. The ballast and bottom shell are adapted to return the holder to an upright position.
