  • Patent number: 5088868
    Abstract: A threaded locking beam nut 20 in which each of a plurality of beams 22 is configured such that confronting side walls 27 and 28 of adjacent beams diverge outwardly away from each other. Any debris located between that confronting side walls of adjacent beams therefore does not inhibit movement of the beams from a locking, expanding position to a free, inwardly-tapered position.
    Type: Grant

  • Patent number: 4911726
    Abstract: An elongated, generally cylindrical fastener engagable with a retaining ring to secure the fastener to a panel. The fastener includes a first set of uniformly-spaced splines extending along its external surface and terminating at an end of the fastener opposite an enlarged head. A second set of longitudinal splines is interleaved with the first set, these second splines being closed at their opposite ends. A separate crossover slot connects together each associated pair of open-end and closed-end splines. A retaining ring having inwardly-projecting tabs is slid onto the fastener with its tabs engaging the first set of open-end splines and the retaining ring is thereafter rotated to slide the tabs across the crossover slots to the closed-end splines. The depth of the crossover slots is less than the depth of the closed-end splines, such that the retaining ring must expand or flex outwardly when the tabs are slid across the slots.

  • Patent number: 4730967
    Abstract: A device 10 for a receptacle secured to a substructure is provided. The torque arm has a first portion 11 and a second portion 18, formed integral and substantially normal to the second portion, so as to provide a load transferring mechanism which prevents rotation of the receptacle as a torque load is applied. The torque arm 10, secured adjacent the substructure is constructed so as to allow use within a range of adjustment as determined by the distance from the substructure end edge 27 to the center of the opening in the substructure 24.
