Patent number: 9394932Abstract: An anchor assembly for walls comprises a toggle member and a strap member pivotally mounted together, and a locking member. In a first position, the toggle member is aligned with the strap member for insertion through a hole in the wall, whereas in a second position, the toggle member extends behind the wall angularly to the strap member which extends from the toggle member through the hole. The locking member is adapted to be displaced along the strap member until it engages the wall and to be locked on the strap member to prevent the locking member from displacing away from the toggle member. Therefore, the locking member and the toggle member are connected by the strap member and imprison the wall by abutting respectively the visible and hidden sides thereof. A fastener introduced through the locking member and wall threadably engages an opening defined in the toggle member.Type: GrantFiled: November 5, 2012Date of Patent: July 19, 2016Assignee: Cobra Fixations Cie Ltee.-Cobra Anchors Co. Ltd.Inventors: Pierre McDuff, Alexandre Pollak, Lang Nguyen

Patent number: 9353782Abstract: 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.Type: GrantFiled: January 26, 2010Date of Patent: May 31, 2016Assignees: COBRA FIXATIONS CIE LTEE, COBRA CANCHORS CO., LTD.Inventors: Pierre McDuff, Richard Labelle, William A.

Publication number: 20120257944Abstract: 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.Type: ApplicationFiled: November 9, 2011Publication date: October 11, 2012Applicant: COBRA FIXATIONS CIE LTEE-COBRA ANCHORS CO.
