Cylindrical puzzle mechanism

摘要

A cylindrical puzzle mechanism (10) comprising a central shaft member (20), with at least two wheels (30) mounted on the shaft member, and a plurality of puzzle components (36) disposed along the outer circumference of each wheel (30). Each of the wheels is independently rotatable about the shaft member. A cylindrical frame (40) is positioned concentrically around the wheels. The frame is rotatable about the wheels and shiftable along the axial direction of the shaft member. The frame comprises at least one driving element at each longitudinal end for shifting a longitudinally aligned row of puzzle components along an axial direction. Two rotatable stoppers (50) for preventing each of the wheels from shifting axially along the shaft, is mounted on the shaft. The stoppers comprise at least one track for receiving a puzzle component thereon. A cap (60) at each end of the shaft member prevents the stoppers from shifting axially along the shaft and for regulating the axial movement of the cylindrical frame.
