  • Patent number: 5622120
    Abstract: A composite apron for a table can be fixed to a bottom surface of the table top between adjacent two of the legs. The apron includes a generally U-shaped wooden shell and a molded core embedded in the shell. The shell and the molded core are hot pressed together. The shell has an elongated vertical main plate section with a vertical inward surface and a vertical outward surface, two vertical end plate sections respectively and perpendicularly projecting from two ends of the inward surface of the main plate section so that the main plate section and the end plate sections cooperatively form a U shape, and a horizontal plate section projecting perpendicularly from a middle portion of the inward surface of the main plate section. When fixed on the bottom surface of the table top, the end plate sections of the shell respectively abut against and are secured to the adjacent two of the legs, while the horizontal plate section abuts against and is secured to the bottom surface of the table top.
