A tumbling toy includes a shell or housing formed of two or more telescoping sections, providing adjustment of the length of the shell and thus the moment of inertia of the toy to affect the tumbling rate. Extending the telescoping housing increases the moment of inertia of the toy, and provides a longer path of travel for the mass within the shell, resulting in a slower rate of tumble for a given slope. The sections may be separated also, allowing the mass contained within to be exchanged for one of greater or lesser mass, which also affects the tumbling rate of the toy. The outer shell sections may be made of plastic or other suitable material, with the moving mass contained therein comprising a marble or the like, or a steel or other metal ball bearing or the like, or a lead sphere or other suitable shape. An internal mass of less than the mass of the shell structure may be provided if desired, as well as masses substantially equal to the shell, or greater than the shell, as desired. The tumbling surface of the toy may be partially or completely coated with a material having a high coefficient of friction (e.g., rubber or soft vinyl, etc.) in order to provide a better grip on a surface and preclude slipping of the toy.

A telescoping tumbling toy, comprising: an elongate shell having a hollow interior and including a first section and a second section, each having a substantially rectangular cross section, a first and an opposite second contact panel each of substantially planar configuration, a closed first end having a convex curvature and extending between said first and said second contact panel, an open second end disposed opposite said closed first end, and a first and an opposite second side wall each of substantially planar configuration and extending between said first and said second contact panel; said shell second section having an exterior shape and size configured to fit closely within and to be frictionally and adjustably gripped within said second end of said shell first section, thereby providing for the relative telescoping of said first section and second section and further providing an adjustable length for said shell; a first weight loosely disposed within said shell, said first weight being free to move between said first end of said first section and said first end of said second section, and; at least a second weight having a different mass than said first weight; said first section and said second section being separable and openable to provide access to said hollow interior of said shell and said first weight is removable from said shell to provide for the interchangeability thereof within said shell, whereby; said first weight may be removed from said shell and said second weight may be installed therein, thereby adjusting the moment of inertia of said toy comprising said shell and said second weight therewithin and accordingly adjusting the tumbling rate of said tumbling toy when said tumbling toy is placed upon a slope to tumble down the slope on said convex first end, said first contact surface, said convex second end, and said second contact surface of said toy; and whereby; said first section and said second section may be telescopingly adjusted relative to one another to adjust said length of said shell, thereby adjusting the moment of inertia of said toy and accordingly adjusting the tumbling rate of said tumbling toy when said tumbling toy is placed upon a slope to tumble down the slope on said convex first end of said first section, said first contact surface, said convex first end of said second section, and said second contact surface of said toy.
