  • Patent number: 8720509
    Abstract: In a tension device for a nonskid chain, a winding reel is supported, so that it can rotate about its axis inside the housing and is prestressed in the winding direction and has a gear rim with teeth arranged along its circumference. A tension line that can be retracted into the housing can be connected to the winding reel, such that a ratchet in a first position blocks a rotational movement of the winding reel in the tension direction by engagement of the ratchet in the teeth. Areas free of teeth on the circumference of the gear rim of the winding reel alternate with areas with teeth.

  • Patent number: 8166616
    Abstract: A turnbuckle for an anti-skid chain that can be mounted on the wheel of a vehicle. A tension cable is connected inside the turnbuckle housing to a winding roll that is pre-stressed in the winding-up direction and mounted so that it can be rotated about its axle. A ratchet wheel with at least one ratchet catch allocated to it is provided on the winding roll and the tension cable can be blocked against its direction of tension by gripping of the ratchet catch into the ratchet wheel. The ratchet catch is moved at least incrementally outwards from the idle position when the wheel isn't moving, in which it is disengaged from the ratchet wheel and the tension cable is not blocked, under the action of the centrifugal force upon rotation of the wheel, and this movement effects a gripping of the ratchet catch into the ratchet wheel.

  • Publication number: 20110284677
    Abstract: A tensioning apparatus (60) for an anti-skid chain to be mounted on a vehicle wheel, a tensioning strand (7) which can be pulled into the housing is connected within the housing (61) to a winding roll (62) with a ratchet wheel (65), which winding roll is pretensioned in the winding direction and rotatable about its axis. A ratchet pawl (64) associated with the ratchet wheel can be moved to the outside under the influence of centrifugal force during wheel rotation, starting from a release position not in engagement with the ratchet wheel and the tensioning strand is not blocked, causing an engagement of the ratchet pawl in the ratchet wheel and a blocking of the tensioning strand against its tensioning direction. A magnetic holding element (68) cooperates with the ratchet pawl and counteracts deflection of the ratchet pawl from the release position during standstill or slow rotation of the wheel.

  • Patent number: 7921521
    Abstract: A deflection device for an anti skid chain includes a chain wheel rotatably stored in a housing for the accommodation of a chain which can be inserted into the chain wheel, and an actuating element that can be moved between a locking position, in which the movement of the chain wheel is blocked in one direction, and an unlocking position in which said blocking is released, and which engages, via a locking pawl actuated by said actuating element, a toothed ring non-rotatably connected to the chain wheel, which is in the form of an internally-toothed ring of the chain wheel. The locking pawl is pivotally mounted within the interior space surrounded by the toothed ring. The locking pawl engages the toothed ring in the locking position but disengages the same in the unlocking position of the actuating element.
