Abstract
A toy building set of building elements (10, 30) having coupling studs (15) and cavities (34) to receive coupling studs (15) in frictional engagement. The cavity (34) accommodates guide means (37) which are adapted to contact coupling studs (15) with a lower friction, and which thereby preferably have a guiding function. This ensures that small and large toy building elements may be built together with a desired coupling force and with a desired friction.
Claims2
A toy building set comprising
- a first toy building element (10) having a side wall with four cylindrical coupling studs (15) arranged with their axes defining respective corners of a first square, and
- a second toy building element (30) having walls (31) which define a cavity (32) with four tubular coupling means (35) arranged with their axes defining respective corners of a second square, and one tubular coupling means (35) arranged with its axis in the centre of the second square,
- wherein each tubular coupling means (35) is capable of fitting in between the four cylindrical coupling studs (15) of the first toy building element (10), and the four cylindrical coupling studs (15) of the first toy building element (10) are capable of fitting in between the four tubular coupling means (35) of the second toy building element (30) so that each of the four cylindrical coupling studs (15) is in contact, with a first friction, both with a respective one of the four tubular coupling means (35) of the second square and with the tubular coupling means (35) in the centre of the second square,
- wherein the second toy building element (30) has, in the cavity (32), partitions (33) with guide means (37) restricting the lateral movement of the coupling studs (15) fitted between two tubular coupling means (35).
