  • Patent number: 4886307
    Abstract: A lock, particularly for trunk, hatch or engine compartments of automotive vehicles or doors or the like, having a mating closure part adapted to be arranged on a hinged part and to be brought into a closed position by means of an external force, comprising a force accumulator which forms the external force charging by displacement of the hinged part. One end of the force accumulator cooperates with a lock part which grips the mating closure part, the other end of the force accumulator acting upon a swingably mounted charging lever adapted to be released before the force accumulator is charged.

  • Patent number: 4682906
    Abstract: The invention concerns a device for the clamping connection of structural parts which are spaced apart from each other by means of a spacer disk arranged within said space and resting by its outer broad side against one structural part. For easier mounting the spacer disk, in order to obtain an axial displacement, derived from its rotation, to the free distance between the structural parts, is provided with helical pitched bearing surfaces opposite which there are form-fitting helical mating, pitched bearing surfaces which are coordinated to the other structural part.
