Claim 9:
10. An anchor assembly for hollow walls, comprising an anchor body and a toggle member moveably mounted to said anchor body, said toggle member being displaceable between first and second positions thereof, wherein in said first position said toggle member is substantially aligned with said anchor body such that the anchor assembly can be rotated for insertion in the wall, and wherein in said second position said toggle member extends behind the wall at an angle relative to said anchor body with said anchor body extending through the hole in the wall, said toggle member being held captive in said first position but being displaceable longitudinally along said anchor body when an appropriate fastener is introduced in said anchor body, deflector means being provided for causing, after a sufficient longitudinal displacement of said toggle member has released the same from a captive state thereof, said toggle member to pivot relative to said anchor body to said second position, said toggle member being adapted to then threadably receive the fastener such that further rotation of the fastener draws said toggle member against a hidden side of the wall with said anchor body being held substantially fixed relative to the wall, wherein said anchor body comprises a proximal collar provided on a leading side thereof with at least one curved locking protrusion extending outwardly from said collar and adapted to engage the wall at the end of the rotary installation of said anchor assembly in the wall and thereby provide resistance to a further rotation of said anchor assembly relative to the wall.
