MODULAR TERRAIN FOR A TOY BUILDING SET

摘要

The modular terrain (8) for a playing structure, such as a toy building set (2), includes a plurality of terrain pieces (8). Some of the terrain pieces (8) have a flat exterior edge (F). The flat exterior edge (F) has no change in height between end points. The distance between end points of the flat exterior edge is one of Y, 2ROOT 2Y and 2 2ROOT 2Y. Some of the terrain pieces (8) have a hill exterior edge (H). The hill exterior edge (H) is only mateable with a hill edge (H) on another of the terrain pieces (8). The hill exterior edge has a change in height between end points of X. The distance between end points of the hill exterior edge (H) is Y. Some of the terrain pieces (8) have a slope exterior edge (S). The slope exterior edge (S) is only mateable with a slope edge (S) on another of the terrain pieces (8). The slope exterior edge (S) has a change in height between end points of X. The distance between end points of the sloped exterior edge (S) is 2Y.
