  • Publication number: 20050265778
    Abstract: A concealed-type leg tube structure, each vertical leg tube has several wide-side locating holes at the upper extent and several narrow-side locating holes at the upper extent that enable conjoinment via matching union blocks having respectively aligned holes and openings. Each union block has the holes disposed in the wide side, with the openings formed in a plurality along the narrow side. Additionally, the vertical leg tube wide-side locating holes are aligned with connector block holes for fastening by means of screws and the vertical leg tube narrow-side locating holes are aligned with the connector block holes for fastening by means of screws. Each connector block has several holes in the two ends, with threaded holes in the center at one side of the connector block, thereby enabling the insertional conjoinment of the horizontal tubes and the connector blocks.
