Toy construction kit

A toy construction kit comprising:

• a plurality of interlockable planar members adapted to form composite structural members, each planar member having two major side surfaces defined by two opposed end edges and two opposed longitudinal edges, each planar member having two spaced apart, resilient wall portions defining therebetween a longitudinal groove extending along one edge of the planar member and each planar member further having a longitudinal tongue extending along the other edge, said tongue projecting outwardly from said planar member in the plane of that member, said groove being adapted to matingly receive the tongue of another similar planar member in a snap fit when the planar members are interlocked at right angles to each other, at least one said planar member defining at least one circular aperture, said kit further including a flexible, cylindrical dowel member defining a slot extending the length of the dowel member whereby said dowel member may be force-inserted into one of said apertures for being compressively retained therein, said kit further including a disc defining a central bore for receiving said dowel member inserted therethrough, said disc having a lug means projecting inwardly into said central bore for being engaged by said slot of said dowel member when said dowel member is inserted through said central bore of said disc, thereby preventing rotation of said disc relative to said dowel member.
