  • Tensioning device for tensioning lines, particularly chains or belts
    Patent number: 4570305
    Abstract: In a tensioning device for tensioning lines having a drive part and a ratchet wheel drivable thereby, a plurality of detent pawls, which are associated with the ratchet wheel, prevent an accidental reverse rotation of the ratchet wheel. The arrangement of the detent pawls is made so that only one detent pawl at a time can come into engagement with a tooth of the ratchet wheel. The reverse rotary stroke of the detent pawl is kept small by an appropriate angular association of teeth and detent pawls.
