PCT No. PCT/DK97/00387 Sec. 371 Date Jun. 3, 1999 Sec. 102(e) Date Jun. 3, 1999 PCT Filed Sep. 16, 1997 PCT Pub. No. WO98/11968 PCT Pub. Date Mar. 26, 1998A toy building set comprises building elements (11, 21, 22) of a first type with coupling studs (10, 20) arranged in a two-dimensional periodical pattern with the coupling studs (10, 20) disposed in rows in two main directions perpendicular to each other in such a manner that the coupling studs (10, 20) also form diagonal rows in diagonal directions relative to the main directions, whereby neighboring diagonal rows are separated by a space having a width (d) wider than zero, and building elements (11, 21, 22) of a second type for interconnecting with building elements (11, 21, 22) of the first type, said building elements (11, 21, 22) of the second type having pairs of parallel coupling walls (12, 23, 24) which define cavities with coupling means for receiving coupling studs (10, 20) on building elements of the first type in a releasable engagement in such a manner that the coupling walls (12, 23, 24) are arranged in main directions between rows of coupling studs, wherein the building set further comprises building elements (40, 50, 60a, 60b, 61a, 61b, 62a, 62b) of a third type for interconnecting with building elements of the first type, said building elements (11, 21, 22) of the first type having pairs of parallel coupling walls (42, 52) that define cavities with coupling means for receiving coupling studs (10, 20) on other building elements in releasable engagement whereby the coupling walls (42, 52) are arranged in diagonal directions in spaces between diagonal rows of coupling studs.
