Patent number: 6796759Abstract: A blind setting rivet assembly capable of permanently fastening one or more sheet metal work pieces or the like together is disclosed. The rivet assembly may be self polishing and self tapping and may also provide a hollow cylindrical threaded bolt head onto which a nut may be affixed to provide a means to removably attach other work pieces, components or the like. The rivet assembly comprises a rivet body having a hollow tubular sleeve and an enlarged flattened head. The rivet body surrounds a mandrel that may have a weakened area of reduced diameter to allow detachment of the mandrel shaft following application of sufficient axial force to the shank. This application of force sets the rivet by causing a tapered shoulder section of the mandrel to deform the rivet sleeve. The mandrel shank may be terminated in a screw tip. This screw tip punctures, spreads, self-taps, and self-polishes an aperture in the work pieces through which the rivet sleeve passes.Type: GrantFiled: January 14, 2002Date of Patent: September 28, 2004Inventor: A. L. Pepper Aasgaard

Publication number: 20030190211Abstract: A self-anchoring fastening device for installation in supports for hanging pipes wires or other articles in ceilings is shaped for a socket to drive the device for an easy installation process. The device comprises a collapsible anchoring portion having radially expanding anchoring strips, which will not pull out of a hole drilled in a support. A drill drills a hole in a support and an expandable anchor is inserted through the hole. Threads internal to the expandable anchor cooperate with threads on a screw inserted therein to collapse the expandable anchor, providing anchoring strips over the hole such that the expandable anchor cannot be pulled out of the hole. A threaded portion of the base of the screw is suitable for attaching the article to be hung. The base may be a swivel head type. The drill may be on the expendable anchor assembly.Type: ApplicationFiled: August 7, 2002Publication date: October 9, 2003Applicant: Illinois Tool Works Inc.Inventor: Richard G. Bodin

Patent number: 6435789Abstract: A self drilling toggle anchor including an anchor member having a head portion at a proximal end, a locking portion at a distal end and a central portion for securely anchoring hardware to a wall, where the central portion defines and borders a channel between the head portion and locking portion. The toggle anchor also includes a drilling member positioned at a distal end of the toggle anchor for drilling through the wall and a toggle member. The toggle member includes a body disposed within the channel of the anchor member, a fitting portion disposed between the body and the drilling member, and upper and lower pairs of shoulders supporting the body within the channel. The body is slidably mounted to the anchor member within the channel and the fitting portion is adapted to releasably engage the locking portion allowing the toggle member to be movable from a releasably locked and fixed first position parallel with a longitudinal axis of the channel to a second position orthogonal to the channel.Type: GrantFiled: December 21, 1999Date of Patent: August 20, 2002Assignee: Powers FastenersInventor: Paul Gaudron

Patent number: 6250865Abstract: A wall anchor assembly has a pair of posts extending from a collar. The collar has an opening for passing a part of a bolt. Distal from the collar, the posts are connected by a connector. An anchor member is captive between the posts and between the collar and the connector. The assembly has a penetrating configuration in which the anchor axis is substantially parallel to the assembly axis, and the anchor body portion and posts form a body portion. A tongue protrudes from an inside surface of a post and engages a groove on the anchor member in the penetrating configuration with the longitudinal anchor axis substantially parallel to the assembly axis, and transmits axial rotation from the collar to the anchor member. The bolt engages a hole in the anchor to draw the anchor member against the wall to clamp the anchor assembly to the wall.Type: GrantFiled: January 24, 2000Date of Patent: June 26, 2001Assignee: Cobra Anchors Co. LtdInventor: Thomas W. McSherry
