Abstract
A puzzle that provides for rearranging different pieces to form a pattern formed from the pieces is disclosed. The puzzle includes at least one generally trilateral piece having three sides, and at least one generally quadrilateral piece. At least two of the sides of the quadrilateral piece have been adapted for engaging the friction enhancing surface on the trilateral piece, so that by surrounding the fixed hub with the trilateral pieces that are separated by the quadrilateral pieces, a continuous round gear surface is formed, that can be used to rotate the trilateral and the quadrilateral pieces together.

A puzzle that provides for rearranging different pieces about a first fixed hub, the rearrangement of the pieces changing a pattern formed from the pieces, the puzzle comprising:
- a plurality of generally trilateral pieces having three sides, the sides of the trilateral pieces following a curvature, each of the trilateral pieces comprising two convex sides and one concave side, the convex sides including gear teeth while the concave side does not include gear teeth;
- and
- a plurality of generally quadrilateral pieces having four sides, each of the sides of the quadrilateral pieces following the curvature, and at least two of the sides of each the quadrilateral pieces being convex and having gear teeth adapted for mating with the gear teeth on the trilateral piece, so that by surrounding the fixed hub with the trilateral pieces such that the trilateral pieces are separated by the quadrilateral pieces a continuous round friction enhancing surface is formed, so that the round friction enhancing surface can be used to rotate the trilateral and the quadrilateral pieces together.
A puzzle that includes pieces that are moved by translation and rotation of the pieces in order to allow the rearrangement of the pieces and produce various patterns from the pieces, the puzzle comprising:
- a support panel, the support panel supporting a pair of hubs and a pair of pinion gears mounted from the panel;
- at least ten generally trilateral pieces, each trilateral piece having two convex sides that follow a curvature of a radius and a concave side, the two convex sides of the trilateral piece including gear teeth and the concave side not having gear teeth;
- and
- at least eleven generally quadrilateral pieces, each having four sides, each of the sides of the quadrilateral pieces being either concave or convex and following the curvature of a radius, and at least two of the sides of each of the quadrilateral pieces being convex and including gear teeth while the concave sides do not have gear teeth, so that by surrounding each of the fixed hubs with the trilateral pieces being separated by the quadrilateral pieces one creates a continuous, round gear surface that can be used to rotate the trilateral and the quadrilateral pieces together by rotating the pinion gears.
