Abstract
Abstract An amusement device that can be utilized as a stacking toy that teaches constructional principles, as a puzzle, or in other forms. In accordance with the invention, there is provided an elongated hollow cylinder having a longitudinal slot therein adapting it to be compressed circumferentially. A plurality of rings proportioned to be slidably fit over the cylinder in stacked arrangement are provided. Also provided are a plurality of cylindrical disks proportioned to be slidably fit within the cylinder in stacked arrangement. First and second end caps are proportioned to fit over and compress the end of the cylinder so as to be yieldingly held in frictional engagement therewith. In a preferred embodiment of the invention, each of the end caps forms the center of an end ring, the end rings having the same outer diameter as the plurality of rings. When the device is assembled in its most natural form, it gives the appearance of concentric cylinders.
