  • Fastening device
    Patent number: 8459919
    Abstract: A fastening device comprising at least one nut, at least one support unit, and at least one spring element, with the nut, the support unit, and the spring element being constructed and matched to each other in such a way that the spring element exerts a force between the nut and the support unit.
    Type: Grant

  • Self-locking screw connection
    Patent number: 8393839
    Abstract: A screw connection having a screw section and a nut threaded thereon. A self-locking effect of the nut on the screw section is achieved in a simple manner in that an intermediate disk is supported non-rotatably on the screw section and is received on the nut so as to be rotatable relative to the nut. The intermediate disk includes a grid distributed around the circumference of the intermediate disk, and the nut carries at least one resiliently elastic, radially displaceable catch formed by a sheet-metal part which, after installing the nut, positively engages the grid to lock the nut against rotation relative to the screw section and intermediate disk. Upon application of a wrench to the nut, the at least one resilient, radially displaceable catch is compressed and drawn out of engagement with the grid, so that the nut can be rotated relative to the screw section.
