ABSTRACT:
A toy construction kit is provided which includes, as basic building elements, a plurality of interlockable plate members, each plate member having a tongue along one side and a groove along the other side whereby two or more plate members can be connected together in tongue and groove fashion to form a composite structural member with the preferred composite structural member being a hollow polyhedron such as a right rectangular prism. The plate members have apertures for receiving dowel members which have a slot extending along their length so that each dowel member may be force-inserted into one of the apertures for being compressively retained therein. The dowel members also have keyhole-shaped apertures on each end for receiving flat panel members and lock pins. Disc-shaped hubs, wheels and angle blocks are provided for being carried by the dowel members. The angle blocks are provided with projecting pins for being received in the apertures of the plate members. The angle block further has a central aperture for receiving a dowel member and has a keyhole-shaped aperture in each projecting pin. The lock pin may be received in the keyhole-shaped aperture of the angle block projecting pin as well as in the keyhole-shaped aperture of the dowel members.
