Publication number: 20220034347Abstract: 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.Type: ApplicationFiled: June 14, 2021Publication date: February 3, 2022Inventors: Pierre MCDUFF, Richard LABELLE, William A.
