Patent number: 11953036Abstract: 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).Type: GrantFiled: March 7, 2017Date of Patent: April 9, 2024Assignee: Cobra Fixations Cie Ltée—Cobra Anchors Co.

Publication number: 20230037370Abstract: An anchor assembly for walls comprises a toggle member and a strap member pivotally mounted together, and a locking member. In a first position thereof, the toggle member is aligned with the strap member for insertion through the wall, whereas in a second position thereof, the toggle member extends behind the wall at an angle relative to the strap member which extends from the toggle member through the hole in the wall. 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 the wall threadably engages an opening defined in the toggle member.Type: ApplicationFiled: April 26, 2022Publication date: February 9, 2023Inventors: Pierre MCDUFF, Alexandre POLLAK, Lang NGUYEN

Publication number: 20220373012Abstract: 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: March 7, 2022Publication date: November 24, 2022Inventors: Pierre MCDUFF, Alexandre POLLAK, Lang NGUYEN, William A.

Publication number: 20220090616Abstract: An anchor for hollow walls comprises a main body and an anchor member. The main body includes a proximal end adapted to be engaged by a rotatable tool to rotate the anchor about a longitudinal axis thereof and to cause it to gradually engage a wall, a distal end adapted to cut through the wall as the anchor is rotated, and a shank between the proximal and distal ends. The anchor member includes expandable wings and a body defining a hole, the expandable wings being in registry with respective slots defined in the shank and being displaceable between collapsed and expanded positions, A threaded fastener introduced in the anchor engages the body of the anchor member such that upon sufficient rotation of the fastener, the body of the anchor member retracts towards the proximal end thereby causing the expandable wings to extend outwardly through the slots behind the wall.Type: ApplicationFiled: December 15, 2019Publication date: March 24, 2022Inventors: Pierre MCDUFF, Lang NGUYEN

Patent number: 10871180Abstract: An anchor assembly for use with hollow panels, comprises a holding member, such as a hook, and an anchor. The anchor is adapted to penetrate a hollow panel, such as a wall, and, once the anchor assembly has been installed to the wall, the anchor is firmly secured thereto while the hook, which is joined to the anchor, is located on a visible side of the wall. The anchor includes a first anchor portion and a second vice portion. The anchor portion, when the anchor assembly is installed to the wall, extends through the hole defined in the wall while the vice portion is located behind the wall. An elbow portion is provided on the anchor between the anchor and vice portions for allowing the anchor to be pivoted when being installed in the wall from a first position where the vice portion is inserted though the wall to form the hole therein and a second position where the vice portion extends behind the wall and in abutment therewith and the anchor portion is lodged in the hole.Type: GrantFiled: June 26, 2018Date of Patent: December 22, 2020Inventors: Pierre McDuff, Alexandre Pollak, Lang Nguyen
