Tapered dovetail mortise and tenon joint structure

A tapered dovetail mortise and tenon jont structure comprising in combination:

• a first component and a second component;
• a tenon portion configured onto a first surface of said first component said tenon portion comprising;
• an outward end surface sloping downwardly from a top edge, which top edge is in the plane of said first surface, and outwardly from said first surface said outward end surface slope forming a first acute angle between the plane of said outward end surface and said first surface of said first component, said outward end surface defined by said top edge, a first and a second outer edge and an outer bottom edge, said first and second outer edges sloping downwardly toward each other forming a second acute angle therebetween and said first and second outer edges terminating at the ends of said outer bottom edge;
• a first and a second inner edge sloping towards one another, and an inner bottom edge said first and second inner edge and said inner bottom edge each in the plane of said first surface, said first and second inner edges terminating at the top end at the junction of said top edge and said first and second outer edges, said first and second inner and outer edges defining a first and a second side surface each of said side surfaces forming a third acute angle with said first surface;
• a bottom surface defined by said two side surfaces, said outer bottom edge and said inner bottom edge and forming a fourth acute angle with said first surface;
• a second surface of said second component having a mortise portion cavity therein, said mortise portion cavity comprising;
• an inward end surface sloping downwardly from a top mortise edge, which top mortise edge is in the plane of said second surface, and inwardly from said second surface said inward end surface slope forming an acute angle between the plane of said inward end surface and said second surface of said second component and said acute angle being substantially equal to said first acute angle of said tenon portion, said inward end surface defined by said top mortise edge, a first and a second inner mortise edge and an inner bottom mortise edge, said first and second inner mortise edges sloping downwardly toward each other forming another acute angle therebetween substantially equal to said second acute angle of said tenon portion and said first and second inner mortise edges terminating at the ends of said inner bottoms mortise edge;
• a first and a second outer mortise edge sloping towards one another, and an outer bottom mortise edge said first and second outer mortise edge and said outer bottom mortise edge each in the plane of said second surface, said first and second outer mortise edges terminating at the top end at the junction of said top mortise edge and said first and second inner mortise edges, said first and second inner and outer mortise edges defining a first and a second mortise side surface each of said mortise side surfaces forming yet another acute angle with said second surface and substantially equal to said third acute angle of said tenon portion;
• a bottom mortise surface defined by said two mortise side surfaces, said outer bottom mortise edge and said inner bottom mortise edge and forming a further acute angle with said second surface and substantially equal to said fourth acute angle of said tenon portion;
• and
• said tenon portion being tightly interfitted to said mortise portion thereby resulting in said tapered dovetail mortise and tenon joint structure.
