ABSTRACT:
A running toy having a chassis with a plurality of pivotably connected portions and a power source for moving the chassis over a surface including uneven portions and obstructions. Each of the pivotably connected portions of the chassis has mounted thereon gears which engage the gears on an adjacent pivotably connected portion so that a driving force provided by the power source is transmitted to the gears of each of the pivotably connected portions in a manner so as to move the running toy. The gears on each of the pivotably connected portions are mounted so that the gears on adjacent pivotably connected portions remain engaged regardless of the pivotable relationship between adjacent portions of the chassis. At least one of the gears on each of the pivotably connected portions has mounted thereon a hub and drive wheel. Because the chassis comprises pivotably connected portions, the running toy can traverse uneven surfaces and obstacles having a wide variety of heights and inclinations. As the running toy traverses across an uneven surface and surmounts obstacles the chassis deforms to enable the running toy to continue moving; thus, creating interesting shapes for the running toy which capture the interest of a user.
