Patent ID: 8764364

Claim:
A wall anchor, comprising: an elongated member comprising a distal pivotable section and a proximal wall anchor section, an outer perimeter of said distal pivotable section being aligned substantially symmetrically and coaxially along a short axis and along a long axis with an outer perimeter of said proximal wall anchor section in an initial configuration, said proximal wall anchor section having an outer cross-section with the short axis and the long axis, a bore therethrough, and a mating surface facing said distal pivotable section in said initial configuration, said distal pivotable and proximal wall anchor sections being pivotably joined so that said distal pivotable section can pivot with respect to said proximal wall anchor section, said distal pivotable section having a sharp forward end, said sharp forward end and said bore being collinear with one another, said distal pivotable section having a cam follower portion with a cammable or cam follower surface opposite said forward end and facing said proximal wall anchor section, said cammable surface positioned so that when said elongated member is in said initial configuration and an elongated activating member is inserted through said bore of said proximal wall anchor section, said activating member will contact said cammable surface and force said distal pivotable section to pivot away from said proximal wall anchor section to an expanded or anchoring configuration, said distal pivotable section having a mating surface facing and contiguous to said mating surface of said proximal wall anchor section when said elongated member is in said initial configuration so that when said wall anchor is driven into a wall, said distal pivotable and proximal wall anchor sections will retain said initial configuration and will not pivot apart or separate until activated to said expanded or anchoring configuration.
