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.

A toy construction kit comprising: a plurality of interlockable thin wall members adapted to form composite, hollow structural members, each wall member having two major side surfaces defined by two opposed end edges and two opposed longitudinal edges, one of said major side surfaces being an interior surface and one of said major side surfaces being an exterior surface in the formed composite hollow structural member, each wall member having two spaced apart, resilient wall portions defining therebetween a longitudinal groove extending along one edge of the wall member and each wall member further having a longitudinal tongue extending along the other edge, said tongue projecting outwardly from the edge of said wall member, said groove being adapted to matingly receive the tongue of another similar wall member in a snap fit when the wall members are interlocked along the side edges, each thin wall member further including an end wall at each end of the thin wall member projecting from said interior surface, said end wall having two slanted surfaces angled inwardly from the two longitudinal edges of said wall member to provide a reinforcing abutment against identical end walls of two other similar wall members when said two other wall members are each in side-to-side tongue and groove snap fit engagement with said one wall member.
