Abstract: A toy building set comprising a plurality of building elements which each are provided with hinge parts, first and second types of hinge parts being shaped complementarily in such a manner that the hinge parts on two building elements may be interconnected releasably so that they form a hinge link between the building elements. The first type of hinge parts is provided with a toothing arranged at a specific distance from the common hinge axis, and the second type of hinge parts comprises a first group which is provided with a toothing arranged at the specific distance from the common hinge axis and a second group of hinge parts which is not provided with such a toothing, said toothings on the first type of hinge parts and on the first group of the second type of hinge parts being directed oppositely to each other in such a manner that they engage each other when the hinge parts are interconnected.

Abstract: A toy building set comprising a plurality of building elements which each are provided with hinge parts, a first type of hinge parts comprising a substantially cylindrical rod-shaped shaft part of a building element, a second type of hinge parts comprising a claw device consisting of two elastic fingers extending outwards from a building element at a distance from each other, so that the two elastic fingers between them form a track which is narrowed at the distal end of the fingers with respect to the building element, so that the rod-shaped shaft part may be pressed into the track through the narrowed part of the track, said hinge parts additionally comprising a third type of hinge parts being provided with a shaft stud which has an external diameter corresponding to the thickness of the rod-shaped shaft part.
