| 20110064537 | Two-Part Device - The present invention relates to a two-part device arranged for threaded assembly comprising a first part having a first threaded section provided on an external generally cylindrical surface and a second part having a second threaded section arranged for threaded engagement with the first threaded section and provided on an internal generally cylindrical surface. A locking opening is provided on the first or second part and a corresponding locking protrusion is provided on the other of the first or second part. When the first and second parts are threaded together by means of the first and second threaded sections, the locking opening and locking protrusion are drawn closer together and upon reaching a threshold the locking protrusion engages with the locking opening. This inhibits the first and second parts from being threadedly disengaged. | 03-17-2011 |
| 20120141226 | LOCKING SYSTEM AND METHOD OF USING SAME - The present invention is a system and method for fastening a second object to a first object that resists unfastening, for example due to vibration or disturbance, until unlocked. The locking system essentially comprises: a girder having one end anchored to the first object, and another end having an externally threaded terminus also defining an internally counter-threaded axial bore; a cap having an essentially planar outer face, an internally threaded transplanar bore for rotational engagement with the terminus of the girder, and a pair of domed arches on opposite sides of the transplanar bore extending from the circumference of the transplanar bore toward the periphery of the cap; and a counter-threaded bolt having a diameter smaller than the transplanar bore, a length sufficient to rotationally engage the axial bore of the girder while inserted through the transplanar bore, and a head having a pin-aperture; a pin inserted through the pin-aperture cooperating with the domed arches to prevent substantial rotation of the cap engaged with the girder terminus and the bolt engaged with the girder axial bore. The system also includes a tightening tool for tightening the cap. | 06-07-2012 |
| 20120224934 | FASTENER - A fastener for securing a wheel rim to an automobile axle unit includes a shank segment, a hollow head segment and a securing pin. The shank segment has first and second threaded end portions and a smooth stop portion interconnecting the first and second threaded end portions. The head segment is formed with an internal thread engaged with the first threaded end portion, and has an abutting portion adapted to abut against the wheel rim and having a cross-section converging toward an open end thereof. The securing pin extends through the head segment into the shank segment for securing the head segment to the shank segment. | 09-06-2012 |
| 20130149068 | Locking System - A system for fastening a first object to one or more other objects that prevents unfastening due to vibration until unlocked. The locking system includes: (a) girder having a first end that has an externally threaded terminus defining an internally counter-threaded bore; (b) a nut having an essentially planar top surface and an internally threaded bore for rotational engagement with the terminus of the girder, wherein the essentially planar top surface comprises at least two notches on opposite sides of the threaded bore of the nut; and (c) a counter-threaded bolt having a diameter smaller than the bore of the nut and a length sufficient to rotationally engage the bore of said girder while inserted through the bore of the girder, wherein the bolt comprises a head cooperating with the at least two notches for preventing substantial relative rotation of the bolt with the girder. | 06-13-2013 |
| 20140377034 | SECURITY SEAL FASTENER SYSTEM - A security seal fastener system includes a fastener, and an enclosure around a head of the fastener that provides visual evidence of access to the head after installation of the fastener. The enclosure may include a washer that is around a shaft of the fastener, and a cap that closes off an access opening in the washer. The cap has a spring that engages a groove in an inner surface of the washer, to lock the cap in place. A flange of the cap and a ridge of the washer prevent access to the spring. The washer has an anti-rotation feature to prevent rotation of the fastening system while the enclosure is intact. The cap has a knockout that can be perforated or removed to allow access to the head of the fastener, for removal of the fastener. The cap may have an identifier, such as a serial number. | 12-25-2014 |
| 20150023758 | DUAL-PREVENTION LOCK DEVICE FOR LOCKING A SCREW AND A METHOD FOR LOCKING THE SCREW - A dual-prevention lock device for locking a screw and a method for locking a screw. The dual-prevention lock device comprises: a lower lock body ( | 01-22-2015 |
| 20160076579 | ATTACHMENT BOLT FOR POSITIVE LOCKING - The invention relates to a fastening bolt ( | 03-17-2016 |
| 411316000 | And utilizing a resilient characteristic of the key, or of a discrete element | 3 |
| 411317000 | With a discrete, resilient element | 3 |
| 20120063863 | LOCKING THREADED FASTENER - A self-locking threaded fastener that can be driven using conventional driving tools. The threaded fastener includes a fastener body and a locking band. The body includes a) a threaded portion and an unthreaded portion and b) an aperture extending radially from the unthreaded portion. The locking band includes a curved portion within the unthreaded portion of the fastener body and a tang extending into the aperture to limit angular movement of the tang with respect to the body. The curved portion terminates at an end having a range of radial movement with respect to the fastener body. When the threaded fastener is turned in a loosening direction, the locking band inhibit loosening of the threaded fastener. | 03-15-2012 |
| 411318000 | Comprising a spring of the coiled type | 2 |
| 20090208309 | Non-Reversible Fastener - Non-reversing fasteners include a bolt having a groove defined along the thread, and a nut having a biased tooth disposed in an internal pocket. When the nut is threaded onto the bolt, the biased tooth does not engage the groove. When the nut is reversed off the bolt, the biased tooth stays in an extended position and engages the groove, preventing it from reversing. A tool positions on the nut and moves the biased tooth from the extended position to a retracted position, allowing the nut reverse off the bolt. The tool can be another nut having a magnet for moving the tooth from the extended to the retracted position. A reverse arrangement can have a bolt with a biased tooth and a first having a groove. A tool in the form of a magnetized rod can fit into an axial bore in the bolt to move the tooth. | 08-20-2009 |
| 20150071730 | FLOATING FASTENER - A floating fastener includes a mounting base member affixed to a first panel member and including an upper locating flange and a lower locating flange disposed at different elevations around the periphery, a rotary fastening member supported on an elastic member in the mounting base member for locking a second panel member to the first panel member through a rotary motion, and a cap member affixed to the head of the rotary fastening member and axially slidably coupled to the mounting base member between the upper and lower locating flanges of the mounting base member and elastically deformably movable over the lower locating flange and stoppable at a bottom side of the lower locating flange when fastening the rotary fastening member to the second panel member to lock the first and second panel member together. | 03-12-2015 |
