Abstract:
Wood trim assembly, which is suitable for attaching solid wood door and window trim, wainscotting, baseboard trim, or corner moulding, to a wall, characterised in that:the assembly includes lengths of solid wood trim, and lengths of spline;each length of wood trim is of constant cross-section along its length;each length of spline is of constant cross-section along its length;each length of trim is assemblable to a respective length of spline;each length of the solid wood trim includes a back face which is adapted to lie against the wall, and a decorative front surface;the shape of the cross-section of the solid wood trim includes a groove formed into the cross-section of the trim from the back thereof;the spline is adapted to fit inside the groove in the trim, in that the cross-section of the groove is complementary in shape and size to the cross-sectional shape and size of the spline;the spline is adapted to be fixed firmly to the wall, prior to the trim being assembled to the spline;the fit of the spline to the groove in the trim is such that, upon assembly of the trim to the spline, the spline being fixed firmly to the wall, the trim is assemblable over the spline by means of a manual pounding action, whereby the trim, after assembly, remains firmly held in place by means of its frictional grip on the spline, and whereby the use of nails or glue to hold the trim is avoided;the spline is formed with a pair of opposed, outwardly-facing, side surfaces;the groove is formed with a complementary pair of opposed, inwardly-facing, side surfaces;the spline is formed with a top surface, being a surface of the spline which lies between the side surfaces, and which, when the spline is fixed to the wall, faces away from the wall;the groove is formed with a bottom surface, being a surface of the groove which lies between the side surfaces of the groove,the fit of the groove relative to the spline is such as to comprise, upon assembly of the groove to the spline, a means for ensuring the side surfaces of the spline fit together, and lie in close operational gripping engagement with the side surfaces of the groove;the fit of the groove relative to the spline is such as to comprise, upon assembly of the groove to the spline, a means for ensuring the top surface of the spline and the bottom surface of the groove lie substantially clear of each other;the form of the spline and of the groove in the trim are such that, when the spline is fixed to the wall, and the trim is assembled on the spline, the said opposed side surfaces of the groove and of the trim lie at a substantial angle with respect to the plane of the wall.
