Anchor assembly with toggle for hollow walls
First Claim
1. 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, said anchor body and said toggle member being provided with at least first and second locking means that cooperate for retaining said toggle member in said captive state when in said first position, said locking means being spaced apart.

Abstract
An anchor assembly (A) for hollow walls comprises an anchor body (400) and a toggle member (231) that is displaceable between a first position wherein the toggle member (231) is substantially aligned with the anchor body (400) such that the anchor assembly (A) can be inserted in the wall (W) via a cutting distal end (325) of the toggle member (231), and a second position wherein the toggle member (231) extends behind the wall (W) at an angle relative to the anchor body (400) which extends through the wall (W). The toggle member (231) is held captive in the first position but is released and then rotated to the second position by a fastener (218) introduced in the anchor body (400). The fastener (218) threadably engages the toggle member (231) thereby drawing the toggle member (231) against a hidden side of the wall (W).

- 11. 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.

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