Abstract
An elongated structural member is erected with one or more similarly formed members. The ends are formed with a pair of angularly disposed chamfers each at a predetermined angle with the longitudinal axis, and having a tenon projection and a corresponding mortise. The tenon and mortise are disposed relative to each other in a respective one of said chambers, at right angles to each other, such that on joining said elements the tenons of one element fit within the mortise of the other element and the chamfered ends abut each other.
Claims5
A structural element for erecting, with one or more similarly formed elements, three dimensional objects comprising an elongated member having an end of rectangular section being joined along said end angularly to another elongated member formed similarly at at least one end, said joining ends being each formed with a pair of angularly disposed chamfers each at a predetermined angle with the longitudinal axis, and having a tenon projection and a corresponding mortise, the tenon and mortise being disposed relative to each other each in a respective one of said chamfers, at right angles to each other, such that on joining said elements the tenons of one element fit within the mortise of the other element and the chamfered ends abut each other.
