Abstract:
1. A building block set having a plurality of building blocks, with at least some of the blocks comprising: a generally transparent body defining a hollow interior cavity and having first and second cylindrical openings thereinto; an internal light source within the hollow interior cavity of the transparent body operable into an illuminated state in response to an electrical input; a non-conductive barrel extending outwardly from the transparent body and coaxial with the first cylindrical opening; a male electrically conductive connector fitted at least partially into the non-conductive barrel and coaxial therewith; a female electrically conductive connector extending into the hollow interior cavity coaxially away from the second cylindrical opening; and an electrical circuit within the interior volume of the transparent body electrically coupled with the internal light source and both the male and female connectors for powering the internal light source in response to an electrical input into either electrically conductive connector; wherein the at least some of the blocks are connectable such that, with the male electrically conductive connector of a first one of the blocks fully inserted into the female electrically conductive connector of a second one of the blocks, the non-conductive barrel of the first one of the blocks will be at least partially seated within the cylindrical opening of the second one of the blocks, and the first one of the blocks and the second one of the blocks are freely rotatable relative to one another about a connection axis therebetween while maintaining electrical contact; and wherein, with the male electrically conductive connector of the first one of the blocks fully inserted into the female electrically conductive connector of the second one of the blocks, the female electrically conductive connector of the second one of the blocks will be, in a radial direction perpendicular to the connection axis, at least partially seated between the non-conductive barrel and the male electrically conductive connector of the first one of the blocks.
