Abstract
A board for use in constructing exterior floors has a rounded or curved convex top surface to shed water, and a complementally shaped rounded or curved concave bottom surface for nesting engagement with the top surface of an adjacent board so that a plurality of the boards may be stacked in stable relationship. The radius of curvature of the rounded top surface is such that a floor formed by a plurality of the boards placed side-by-side provides a comfortable surface on which to stand and walk. In a modification, the bottom surface has a plurality of stress-relief channels formed therein to prevent cupping or warping of the board.
Claims20
A board for use in constructing a flooring surface for exterior use, said board having a top surface, a bottom surface and opposite side edges, said top surface being manufactured to have a slightly rounded or curved configuration from a longitudinal center line thereof downwardly toward each side edge, thereby defining a convex top surface which sheds water and at the same time is comfortable to walk on, and said bottom surface having a concave configuration for nesting engagement with the top surface of another board so that a plurality of the boards may be stacked one on top of the other with the stability of conventional boards having flat top and bottom surfaces.
A wood decking board for use in constructing a flooring surface for exterior use, said decking board having a convex top surface, a bottom surface, opposite side edges, and curved growth rings, said top surface being smoothly and symmetrically curved from a longitudinal center line thereof downwardly to each side edge, said top surface having a radius of curvature that is approximately five times as great as the width of the board, thereby defining a smoothly shaped and shallow convex top surface which sheds water and at the same time when a plurality of the boards are placed in side-by-side relationship to one another to form a flooring surface they result in a substantially flat surface that does not produce a tactile sensation of an irregular surface, thereby providing a flooring surface that is comfortable to walk on and which is capable of satisfactorily supporting furniture and the like, and said convex top surface is formed in the board so that the growth rings are oriented in the same general direction as the curvature of the top surface, thereby insuring that the hoard will always be installed with the growth rings properly oriented to minimize the effect of cupping.
A decking board for use in constructing a flooring surface for exterior use, said board having a convex top surface, a bottom surface and opposite side edges;
- said convex top surface being manufactured to have a radius of curvature with a slightly rounded or curved configuration extending across the top surface from one side edge to the other, defining a difference in thickness between the longitudinal centerline and the opposite side edges, with the ratio of said difference in thickness to the width of the board being about 1:40;
- and said convex top surface serving to shed water from said board when exposed to weather, and at the same time, when a plurality of said boards are laid in side-by-side relationship, presenting a surface that is comfortable to stand and walk on.
