Patent ID: 8915039

Claim:
A solid-wood rigid panel comprising: two generally-planar, mutually parallel solid-wood boards each having a plurality of mutually-parallel dovetail-connection channels running generally along an internal major surface of each of the boards; and a solid-wood central keying structure disposed between the two mutually-parallel solid-wood boards, the central keying structure comprising a plurality of two-sided sliding dovetail keys sized to slide within the dovetail-connection channels to secure the two mutually-parallel solid-wood boards to each other via sliding dovetail connections to the central keying structure; wherein the solid-wood panel forms at least part of a structure selected from a body of a door and a body of a tabletop, wherein the dovetail-connection channels are generally perpendicular to a length of the structure, wherein a wood grain direction of the central keying structure coincides with a length of the dovetail-connection channels, and wherein a wood grain direction of each of the two mutually-parallel solid-wood boards is perpendicular to the length of the dovetail-connection channels.
