Dovetail joint construction

A dovetail joint construction comprising a female member having a dovetail groove in a planar surface of the female member for receiving a dovetail member, said dovetail member comprising;

• a male member;
• a male dovetail projection upstanding from a planar surface of the male member for insertion into the female member dovetail groove to secure the male member to the female member forming a dovetail joint therewith with said planar surfaces in abutting relation;
• and
• a wedge projection upstanding from said male member planar surface externally of and adjacent to said male projection for wedging against the female member planar surface in interference fit to frictionally secure the members together joined by said groove and dovetail projection.

A male dovetail joint member mating with a dovetail groove formed in a first planar surface of a female member, said male member comprising:

• a first member having a planar second surface;
• a first projection for mating with the dovetail groove and extending in a given direction parallel to said second surface and being trapezoidal in section transverse the given direction, said first projection upstanding from said second surface and having opposing planar side faces each defining a plane intersecting the second surface at an angle less than 90.degree. in mirror image relation such that the trapezoidal projection is narrowest at a region where it connects to the first member at said planar second surface and said side faces overhang said planar second surface, said side faces each extending in said given direction;
• and
• a wedge projection upstanding from said planar second surface in a region intermediate said planar first and second surfaces and external to said first projection, said wedge projection having a height above said planar second surface to wedge against the first surface in interference fit therewith.
