Abstract:
1. A structure comprising an interlocking flush joint system, said interlocking joint system comprising: a first member with a mortise having first, second, third, fourth, fifth, sixth and seventh planar adjacently connected mortise surfaces, each mortise surface being oriented either parallel or perpendicular to each of six other of said mortise surfaces, said seventh mortise surface being coincident with a side face of said first member, a second member having a tenon with first, second, third, fourth, fifth, sixth and seventh planar adjacently connected tenon surfaces, each tenon surface being oriented either parallel or perpendicular to each of six other of said tenon surfaces, each tenon surface having a full length and full width conforming flush against a full length and full width of a respective one of said mortise surfaces, said third tenon surface being an end face of said second member, a first flush mortise corner formed in said second member by said first and second tenon surfaces connecting perpendicularly to one another, said corner receiving an abutment formed by said first and second mortise surfaces connecting perpendicularly to one another, a flush mortise formed by said second, third, fourth and fifth mortise surfaces, said flush mortise receiving a substantially rectangular flush tenon formed by said second, third, fourth and fifth tenon surfaces, each of said second surfaces sized and arranged to mirror each of said fourth surfaces to define two opposite sides of said flush tenon and two opposite sides of said flush mortise, and a notch formed by said fifth, sixth and seventh tenon surfaces, said notch receiving a mortise cantilever formed by fifth, sixth and seventh mortise surfaces, each of said fifth surfaces sized and arranged to mirror each of said seventh surfaces to define two opposite sides of said notch and two opposite sides of said mortise cantilever, and whereby said first mortise surface and said fifth mortise surface lie in a common plane and define an opening there between, said opening receiving a portion of said second member there through and being smaller than a distance between said opposite sides of said flush tenon thereby inhibiting removal of said flush tenon from said flush mortise.
