Patent number: 6052274Abstract: A fastener temporarily attaches articles through aligned apertures in the articles including a nut plate allowing the articles to be assembled by one assembler. The fastener has a flange, a cylindrical sleeve, and a solid pin. The flange ensures that the fastener does not pass completely through the aligned apertures. The sleeve supports articles and couples with the flange on one end of the sleeve and the solid pin on the other end of the sleeve. The solid pin can support a nut plate and further engages the threads in the nut plate through friction. The juncture between the sleeve and the solid pin is formed to allow the pin to break away from the cylindrical sleeve when pressure is applied. A screw or other threaded fastener is inserted through the cylindrical sleeve and pressed against the solid pin. Once the solid pin breaks away, the threads on the screw engage with the corresponding threads on the nut plate.Type: GrantFiled: September 15, 1998Date of Patent: April 18, 2000Assignee: Dell USA, L.P.Inventor: Ralph Remsburg

Patent number: 5593262Abstract: A removable plastic automobile boss has a body formed with a bore for receiving a threaded fastener. A flat seating flange is formed on the front portion of the body, the flange including left and right ears respectively protruding outwardly from the left and right sides of the body. Top and bottom ramp-shaped engagement abutments are formed on the body. Further, a slit is formed on the body such that the top and bottom engagement abutments ride against the periphery of an instrument panel receptacle when the boss is advanced into the receptacle, thereby causing the top and bottom halves to be urged toward each other to permit the boss to be fully inserted into the receptacle. The front portion snappingly resumes an engaged configuration when the engagement abutments clear the periphery to sandwich the periphery between the engagement abutments and the seating flange to engage the boss with the instrument panel.Type: GrantFiled: May 25, 1995Date of Patent: January 14, 1997Assignee: Chrysler CorporationInventors: Dale G. Gedeon, Mark B. Schatz, Robert J. Stephens, Shawn E. Roberts

Patent number: 5573362Abstract: A clip comprised of a head portion retained to a panel, and a leg portion inserted and retained in a mounting hole. The leg portion has a leg plate, elastic legs which project out from the longitudinally-extending transverse direction sides of the leg plate so as to form curved surfaces which face each other, and pawl portions protruded from the elastic legs. Curved outer surfaces of the pawl portions are disposed on a circular locus around central points on side surfaces of the leg plate, and have a greater curvature than the curvature of the mounting hole. As a result, when the leg portion is inserted into the mounting hole, the entire peripheral surfaces of the pawl portions do not contact the peripheral wall of the mounting hole, but only point-contact the peripheral wall of the mounting hole at points. Therefore, frictional force between the mounting hole and the leg portion is small, and insertion force is reduced.Type: GrantFiled: June 7, 1995Date of Patent: November 12, 1996Assignee: NIFCO Inc.Inventors: Goro Asami, Eiji Ueno

Patent number: 5537714Abstract: A plastic grommet for use on metal studs in wall construction protecting wires, cabling, conduit, and the like. The grommet also makes the passing of such utilities easier and quieter. The grommet will function singularly or assembled to a clone. The grommet includes a cylindrical body having an enlarged flange on one end with radially projecting spring snaps on the exterior of the body whereby the grommet may be inserted in a sized hole in the web with the hole edge captured between the snaps and flange. On the other side of the flange are diametrically opposed axially projecting spring fingers. The flange also has two diametrically opposed holes, the fingers and holes being positioned so that two grommets can be joined flange-to-flange by axially rotating one with respect to the other. Two such grommets thus assembled on opposite sides of a rectangular or other irregular or pre-punched hole in the stud web capture the web between the flanges.Type: GrantFiled: September 1, 1994Date of Patent: July 23, 1996Assignee: Erico International Corp.Inventors: Edward J. Lynch, Jr., Raymond S. Laughlin

Patent number: 5536125Abstract: A fastening assembly for securing plastic panels (50) to metallic substrates (52) is provided in which a metallic nut (14) is mounted in snap-fit relationship on plastic insert (12), which is in turn engaged in snap-fit relationship on the metallic substrate (52). The nut (14) slidably engages the plastic insert (12) to permit certain movement along an axis perpendicular to the axis of the insert (12) to provide thermal compensation for the mounted plastic panel (50). The nut (14) itself utilizes the same guide lug structure (26) of the insert member (12) to both effect snap-fit retention of the nut (14) on the insert (12) and to guide the sliding movement of the nut (14) with respect to the insert (12).Type: GrantFiled: December 27, 1994Date of Patent: July 16, 1996Assignee: Ford Motor CompanyInventor: William D. Gaw, Jr.

Patent number: 5511919Abstract: A fastening element is provided having a fastener body including a first side and a second side, with resilient locking prongs extending from one side of the fastener body. The fastener body can include either a cavity or a shank on one of the sides. The shank or cavity can be provided with either a channel or an engagement lug for mating with a complimentary fastening element. One side of the fastener body can also be provided with a cam surface or a resilient surface to inhibit rotation between mated complimentary fastening elements.Type: GrantFiled: August 3, 1994Date of Patent: April 30, 1996Inventor: Dane C.

Patent number: 5503492Abstract: A spring formed from strip steel crimped on a threaded bolt for receiving a threaded member preferably having four arms separated by 90 degrees to form a cross and wherein the ends of the legs are cambered in order to provide greater bearing surface against each of the two walls of a corner in a tubular member when the spring member is inserted into the tubular member. Where the arms extend from the well of the spring, the arms are slightly notched in order to provide for automatic indexing. When the spring is compressed the wells formed by the spring contact the walls of the tubular member.Type: GrantFiled: March 31, 1994Date of Patent: April 2, 1996Assignee: Robert E.

Patent number: 5346347Abstract: A parts fastener has a body having at one of its ends a flanged head projecting from the body. For that purpose the body evinces a central cavity communicating with the outside and includes at least a wall portion of which the inner side bounds part of the cavity, and which elastically deforms under an external force applied to the wall portion. The wall portion has, on its outer side, a projection which together with the head flange bounds a jaw by means of which the fastener may be inserted into the part to which it must be affixed. The projection opens on account of the deformation of the wall portion and frees the part and the fastener from each other. The device may also include means to cause the deforming force from the outside.Type: GrantFiled: January 21, 1993Date of Patent: September 13, 1994Assignee: Clipp-OffInventors: Michel Barikosky, Christian Girardiere
