ABSTRACT:
A construction toy formed from a plurality of building blocks. A primary form of building block is formed as a wafer-shaped rectangle having top and bottom surfaces formed of complemental interconnectable arrays of posts or rectangular vanes on a top surface and parallel-walled channels on a bottom surface allowing the blocks to stack and lock top-to-bottom. The sides of the primary building blocks have complemental prominences and orifices or projections and grooves which can connect together allowing the blocks to stack side-to-side. Orifices are also located in a portion of the top surface, usable in any way the orifices of the side surfaces are usable. A secondary form of building block is a round wafer-shaped block with beveled gear teeth along a side wall of the block. The secondary block has posts on a top surface and vanes, similar to the primary blocks, and has a hub on a bottom surface. The hub is rotationally receivable within the orifices of the primary blocks. Secondary blocks may be attached to primary blocks in an interfacing pattern allowing a user to construct representations of both planar gear pairs and beveled gear pairs. A third form of building block, as does the primary form, among other things, attaches rotationally to the top surface of the secondary block, acting as an input driver for an assembly of secondary blocks.
