Assignee:

Cobra Anchors Co. Ltd.

International Classification:

F16B 13/06

US Classification:

411 801, 411 601, 411 32, 411342

Abstract:

An anchoring device for insertion in a hole provided in a structure such as a wall (hollow or solid) comprises proximal and distal sections. The proximal section includes a head defining an aperture for receiving a fastener, and the distal section includes a pair of expandable wings displaceable between collapsed and expanded positions. Each wing is biased towards its expanded position such that the wings can engage the structural material delimiting the hole or a distal surface of the structure. The distal section comprises, proximally of the wings, a variable-length flexible portion for allowing the wings to engage the distal surface of the structure for various structure thicknesses. The distal section comprises, distally of the wings, a tip section adapted to spread outwardly when engaged by the fastener. The proximal section comprises a pair of legs each having a toothed rack for engaging the structural material.

Abstract:

An anchor () for mounting to a hollow wall (W) made of friable material comprises a proximal flanged end () adapted to be engaged by a rotatable tool (B) to rotate the anchor () about a longitudinal axis (A) thereof and to cause is to gradually engage the wall (W). The anchor () also includes a distal end () adapted to cut through the wall (W) as the anchor () is rotated, and a shank () extending between the proximal and distal ends (). The shank () includes at least one expandable leg () that is in a collapsed position thereof when the anchor () 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 () has been mounted to the wall and is in a first position thereof. The wall anchor () includes an outer thread () that securely engages the wall (W). A threaded fastener (B), e. g.

US Classification:

411 29, 264318

Abstract:

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