Plastic mounting plate for furniture fittings - has thin walled hollow rear anchoring studs radially expanded and axially compressed by driven in plug (AT 15.3.75)
A mounting plate or backing plate of plastics for fittings to be attached to furniture has hollow, generally cylindrical studs projecting from its rear face and having external serrations for anchoring into the furniture board by internal splaying of the hollow stud. - Each hollow stud has a central cylindrical cavity, and is followed by a further cylindrical cavity of smaller diameter in the mounting plate itself. - A plug to be driven from the rear into the hollow stud has a main cylindrical part designed to fit into the cylindrical cavity and a flanged head or wider part at the top. The cylindrical cavity and a flanged head or wider part at the top. The cylindrical wall of the stud is sufficiently thin to be axially compressed when the plug is driven hard into it, so that the stud expands radially and binds firmly into the board of the furniture. - In addition, the axial compression of the stud has the effect of shortening it and pulling the mounting plate tightly against the front face of the furniture even through initially it may have been a loose fit.(0/4)
