<p>A toy building block system includes a plurality of blocks, each having an array of cylindrical projections extending from one surface thereof and a like array of socket-like receptacles in the opposite surface for stackable interconnection. In addition, one end of each block includes a pair of hinge arms extending therefrom, with a pair of detent knobs formed on the confronting interior surfaces of the arms. The opposed end of each block includes opposed recessed surface portions, each having a detent recess to receive the knob of a hinge arm of an adjacent block in snap-engaging, pivotting fashion. The blocks thus may be joined end-to-end in pivotting fashion by the hinge arms, as well as stackably in column fashion by the projections and receptacles, or any combination thereof.</p> |
