  • Patent number: 4651545
    Abstract: A combination lock has a plurality of shaft-mounted setting discs located behind viewing windows in a front plate of a lock housing. The setting discs have setting symbols and detent engage in individual angular positions. Locking sleeves are adjacent and cooperate with the setting discs. A spring-biased rocker has feeler projections with feeler surfaces which cooperate with engagement spaces in the locking sleeves. The rocker is adapted to engage a mating locking part of the lock. When the lock combination is properly set, the engagement spaces lie in respective positions opposite the feeler projections. The rocker comprises a U-shape including U-arms which surround the setting discs and the locking sleeves. The setting discs are mounted on respective shafts, and the rocker has an axis extending transverse to a plane through the respective shafts of the setting discs.

  • Patent number: 4610152
    Abstract: A combination lock adapted for securing skis, bicycles and the like, having a lock housing in which setting disks for setting a lock combination are rotatably supported and from which housing there extends fixed thereto, one end of a loop, the other, free end of which is insertable into an insertion channel in the lock housing and is engageable by the inners of the lock. In this respect within the insertion channel of the lock housing a latch is provided for catching the free end of the loop. The latch is seated, displaceable against spring biasing, on a setting-disk mounting shaft and, when the lock combination is correctly set, is disengageable, by a collar on the setting-disk mounting shaft which continues into an outwardly extending actuating button, by displacement together with the mounting shaft.
