  • Patent number: 4907771
    Abstract: This invention relates to a hanger with improved positioning structure which can be fastened onto a wall by flat head screws. The flat head screws are concealed from view and are protected from breaking away from the wall. The hanger includes a brass mounting plate which is fastened onto wall surface separately from a brass cover plate by screws, which match with anchors in the wall. A spring is mounted on a mounting plate stem of the brass mounting plate. The brass cover plate is mounted on the mounting plate stem of the brass mounting plate so as to compress the spring cover the brass mounting plate, and conceal the flat head screws. A ceramic inset is set in a circular recess of the brass cover plate to make the structure more attractive. A connector connects with the mounting plate stem of the brass mounting plate by a pivot bolt so that the brass cover plate and the ceramic insert can be firmly retained between the brass mounting plate and the connector.
