TOY CONSTRUCTION SET

摘要

A toy construction set includes a plurality of blocks (30) and at least one base plate (12). Each of the blocks has one or more axially shiftable and rotatable coupling cams (54) mounted therein which can be projected from the bottom of the block to effect vertical attachment with another block or with the base plate, using a suitable hand tool (300) to do so. The preferred base plate contains a number of appropriately located coupling cams (54) so that it can be atached either above or below a number of blocks.
