Expansible mounting assembly

A mounting assembly for mounting an object to a wall having an outer surface formed of plaster wallboard comprising:

• a molded plastic bracket having a hollow barrel formed therein and having means formed thereon for supporting an object from said bracket, said bracket having a flat rear surface adapted to be placed against a flat vertical surface of plaster wallboard for mounting thereto;
• a molded plastic anchor including a stem section, a head section, and a pointed end section, said head section being located at one end of said stem section, and said pointed end section being located at the opposite end of said stem section from said head section;
• an axial bore extending through said head section and through at least a portion of said stem section;
• an external peripheral surface on said said section of said anchor, said external peripheral surface having annular ribs formed thereon;
• slot means formed in said stem section of said anchor for defining two opposed stem members, said slot means extending along a major portion of the length of said stem section between a point adjacent said axial bore and a point adjacent said pointed end section, said two opposed members each having a free end adjacent said pointed end section, said anchor including means for releasably joining each of said free ends;
• said molded plastic anchor being adapted to be inserted through said hollow barrel and to be driven into the plaster wallboard located in juxtaposition to said rear surface of said bracket;
• means for orienting said stem section within said barrel;
• and
• an expansion pin adapted to be inserted into said axial bore and into contact with said projections to urge said two opposed stem members radially outwardly and to release said releasable joining means.
