Scale building set and elements

Claim 1

In a scale building set, a flat panel element of a selected geometric shape and scale dimension having a beaded, generally circular joint portion along each peripheral edge thereof, and a narrowed weblike panel portion extending inwardly of the beaded joint portion, a connector element having a peripheral socket joint portion for joining a side of said panel element with an adjacent side of another panel element, said socket portions being slotted to form an entrance for insertion of said beaded joint portion and being formed of a yieldable extruded material, said socket portions having opposing side extensions projecting outwardly from a central body and turning inwardly toward one another at their ends to extend beyond a semicircular section of the beaded joint portion, said panel and connector elements being geometrically and dimensionally interrelated to conform to a selected scale wherein smaller panels are interconnected by connector elements to form an assembly having the same external dimensions as a larger panel element, said joint portions having correspondingly shaped mating contact surfaces concentrically arranged and in frictional engagement substantially throughout the circumferential extent of the socket portion to provide uniform frictional engagement between said mating surfaces when one element is rotated relative to the other for clampingly joining said panel and connector elements while permitting forced rotational and slidable movement therebetween, said panel element being beveled across each corner, the sides of said joint portions being spaced apart and said panel portion being sized to permit at least 90* of rotation between said elements.
