  • Patent number: 11667409
    Abstract: A separation device for a spacecraft or launcher comprising a nut divided into at least two nut portions locked to each other by a locking device in a locking position. A releasing device is arranged to switch the locking device from the locking position to a releasing position. The separation device comprises at least two bearing elements arranged between the locking device and the nut. The nut comprises an outer envelope surface which comprises as many indentations as the number of bearing elements and locking surfaces between the indentations. In the locked state each bearing element is jammed between the locking surface and an inner envelope surface of the locking device and in the released state each bearing element is positioned facing the indentations.

  • Patent number: 5197695
    Abstract: A locking device for a band or the like comprising a housing having one end fastened to a first portion of the band. The housing extends in the direction of the prevailing tensile force and is formed with a guide for guiding a link means. This comprises a fastening element fastened at its first end to the second portion of the band and at its second end journally connected to a second link at a distance from its first end. The second link is, at its first end, journaled around an axis provided in the housing transverse to the longitudinal direction of the housing. The locking device also comprises a third link journaled at the first end of the housing and a dowel element which, l via the third link, is able to prevent the second link from being turned around the axis to a position where it is released from the axis so that the locking device is opened.
