  • Patent number: 11140874
    Abstract: A retractable leash device (10, 53) for rolling up and unrolling a leash (13), especially for leading an animal, includes a leash roller (22) mounted rotatably on a carrier and a resetting device to reset the leash into a rolled-up position, in which the leash is wound up onto a leash roller. A blocking feature blocks the unrolling of the leash. A transmission is coupled to the leash roller and brings about blocking when a predetermined leash length is unrolled from leash roller. A simple configuration with high operating reliability and low wear is provided with the transmission having a first transmission element arranged rotatably on the carrier and a second transmission element arranged nonrotatably on the carrier. The first transmission element and the second transmission element have an outer circumference and an inner circumference associated with one another, which mesh with one another at least in an active state.

  • Patent number: 9439400
    Abstract: A device (10, 36, 39) for rolling up and unrolling a leash, especially for leading an animal, includes a leash roller (11) and a blocking device (22), which has an actuating element (37) and a locking element (26). The leash roller (11) can be actuated by the blocking device (22) for blocking an unrolling motion of the leash roller (11). The actuating element (37) can be actuated by an actuation motion. A locking motion of the locking element (26) can be triggered for blocking the unrolling motion of the leash roller (11) based on the actuation motion of the actuating element (37). Generation of a disturbing noise, with the blocking device, is avoided by the actuation motion of the device (10, 36, 39) being transferred by a transfer device (23) into a locking motion of the locking element (26) that is greater than the actuation motion.
