Anchor assembly with toggle for hollow walls

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 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.

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 toggle member has opposed proximal and distal ends, a recess being defined in said proximal end of said toggle member and being adapted to receive a leading section of a rotary tool, such that the leading section of the tool engages said recess in said first position, wherein when the rotary tool is engaged in said recess a rotation of the rotary tool causes said toggle member to rotate for inserting said anchor assembly in the wall with said distal end of said toggle member being adapted to cut through the wall.

An anchor assembly for hollow walls, comprising a machine screw, an anchor body and a toggle member moveably mounted to said anchor body with a threaded hole being defined in said toggle member, 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 the machine screw 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 machine screw via said threaded hole such that further rotation of the machine screw 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 threaded hole defines a thread prior to the machine screw engaging said toggle member.

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 is completely made of a plastics material, and said toggle member is completely made of a metallic material, temporary locking means being provided between said anchor body and said toggle member in said first position for providing rigidity to said anchor assembly.
