Abstract (en)
[origin: EP0333996A2] Toy building blocks with a coupling element projecting at one end face can be connected to adjacent toy building blocks via corresponding openings. For this purpose, the coupling element is inserted in an opening and rotated by 90 DEG . <??>In order to obtain a safeguard against rotation in the region of such a connection, at least one elevated surface is constructed to the side of the coupling element on the outside surface, at which the coupling element projects, which elevated surface can engage on the opening of an adjacent toy building block to be connected. <IMAGE>
