摘要： An anchor (910) for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end (918) adapted to be engaged by a rotatable tool (B) to rotate the anchor (910) about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor (910) also includes a distal end (912) adapted to cut through the wall (W) as the anchor (910) is rotated, and a shank (920) extending between the proximal and distal ends (918, 912). The shank (920) includes at least one expandable leg (924) that is in a collapsed position thereof when the anchor (910) is rotated to mount it to the wall (W) and that is located distally beyond a non visible surface of the wall (W) once the anchor (910) has been mounted to the wall and is in a first position thereof. The wall anchor (910) includes an outer thread (922) that securely engages the wall (W). A threaded fastener (B), e.g. a screw, is adapted to be introduced in the anchor (910) and to threadably engage the same distally of the leg (924) such that sufficient rotation of the threaded fastener (B) retracts the distal end (912) towards the proximal end (918) thereby causing the leg (924) to displace to a laterally expanded position thereof and to engage the non visible surface of the wall (W).

摘要： 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).
