Abstract: A simple preschool assembly toy for young children which comprises at least three relatively large parts that are assembled together by the child to provide a representation of a recognizable object such as a toy vehicle and driver. A first and a second part are positioned adjacent to one another and include mechanically inter-engaging elements which limits relative movement between these parts only in a first direction, while allowing them to be separated in a second direction generally transverse to the first direction. A third part is positionable adjacent to the other parts, and second inter-engaging elements are provided on the third part and one of the other parts to limit relative movement between the parts in the second direction. The second inter-engaging elements may be engaged and disengaged by motion only in the second direction; as for example by the provision of magnets.
