Abstract: A 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 bu

Abstract: A baby rattle (1) comprising two rattle portions (2,3) and an elongated elastic spacer element (4) which connects the two rattle portions (2,3), wherein the two rattle portions (2,3) have mutually complementary coupling portions (5,6) which allow the two rattle portions (2,3) to be coupled to each other, and wherein the weight of the two rattle portions (2,3) and the rigidity of the elastic spacer element (4) are adjusted relative to each other so that the elastic spacer element (4), like a column, may in itself support the one rattle portion (2,3) when the elastic spacer element is maintained substantially vertically upright relative to the second rattle portion (3,2), and wherein the mutually complementary coupling portions (5,6) possess sufficient coupling force to keep the two rattle portions (2,3) together despite the force applied from the elongated elastic spacer element (4) by coupling of the rattle portions (2,3).
