Abstract
The present invention is a toy construction block system which includes a plurality of toy construction blocks and a plurality of interblock connectors. Said blocks each have a main outer structure having a top, four sidewalls and an open bottom. The top has a plurality of symmetrically arranged elongated projections for interlocking with other, similar blocks and the open bottom has an underside to said top which itself has an elongated friction post extending therefrom. The friction post is hollow and is centrally and symmetrically located on the underside. The critical features are that the top has thereon a top recess in alignment with the friction post, a bottom recess within the friction post of the block, and at least one of the four sidewalls has a side recess therein adapted to receive an interblock connector. In preferred embodiments of said interblock connector, each connector has at least an elongated body and first and second ends. At least one of said first and second ends has means for attachment to at least one of said construction blocks. In other embodiments, one of said first and second ends has means for connecting with another interblock connector to enable the…
