  • Publication number: 20200000065
    Abstract: Described is a retractable leash device (1) as well as a process for rolling up and unrolling a leash (4) for leading an animal. The retractable leash device (1) has a handle (2) and a housing (3) for the accommodation of the leash (4) which can be rolled up and unrolled, and a mechanism which exerts a restoring force at least at times on the at least partly unrolled leash (4) is provided in the housing (3). An outlet opening (6), at which the leash (4) comes out of the housing (3), can be moved into at least two positions in relation to the handle (2).

  • Publication number: 20180338474
    Abstract: A retractable leash (10, 38) for rolling up and unrolling a leash (12), especially for leading an animal, with a leash roller (13), which is mounted rotatably on a carrier (11) and can be retracted by a retracting device into a rolled-up position, in which the leash (12) is wound up onto the leash roller (13); and with a blocking device for blocking the unrolling of the leash (12) from the leash roller (13), the radius of action of an animal being led can be effectively limited in a gentle and especially jerk-free manner by the blocking device having a brake (17) frictionally engaged with the leash roller (13) even in case of a bolting animal.

  • Publication number: 20180317456
    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.

  • Patent number: 9420765
    Abstract: A plug-in lock (1) for connecting flexible and/or rigid line elements (43, 44) with a plug-in part (11) and a receiving part (12), whereby a positive-locking connection (14) is provided for transmitting a tensile force for establishing a detachable connection of the plug-in part (11) to the receiving part (12). In order to prevent an unintentional detaching of the connection of the plug-in part (11) from the receiving part (12) even at high tensile forces and at the same time to make possible a simple operability and cost-effective manufacture, the plug-in lock has a securing device (13, 25) separate from the positive-locking connection (14) for preventing an unintentional detaching of the positive-locking connection (14). The securing device (13, 25) has an actuating mechanism (33) for detaching the securing device (13, 25).

  • Patent number: 8528850
    Abstract: A braking device for a rope pulley of a mechanically retractable and extendable leash for walking animals is provided. The rope pulley is supported in a housing such that it is rotatable in an unwinding direction against the force of a spring and in a wind-up direction under the influence of the spring force and cooperates with a brake button of the braking device in order to stop rotation of the rope pulley. The rope pulley is connected to a brake disk that is rotatable relative to the rope pulley against a damping force and that can be locked to the housing.

  • Publication number: 20090114759
    Abstract: An attachment for securing a leash on a roll is provided. The roll is attached rotatably in a housing, whose wall facing the roll is arranged at a separation from the peripheral surface of the roll. The leash passes through an opening in the wall out of the housing and is attached on the roll via a terminal loop. The loop is formed by a folded-over terminal leash section that is secured to the leash itself. According to the invention, it is proposed that with formation of the loop, the attachment of the leash end to the leash lies in or in front of the opening in the pull-out direction outside the housing in the fully unwound state of the leash.

  • Patent number: 7168393
    Abstract: A leash assembly having a strap or leash that can be reeled or unreeled for walking animals. The assembly has a handle and a housing attached thereto in which the strap is arranged on a turnable roller device for being reeled or unreeled. The assembly also includes a brake key that can stop and prevent rotation of the roller device to restrict a part of the strap extending externally of the housing to a desired length. In addition, the assembly includes an exit opening through which the strap extends externally of the housing. Preferably, the exit opening is formed as a slit, and the slit has a central region along its longitudinal extension that has an enlarged opening porfion extending laterally from at least one side of the slit.

  • Patent number: 6148773
    Abstract: A retractable animal leash assembly including a housing suitable for being held in one hand is disclosed, with a freely moveable, but, if desired, lockable leash being arranged partially coiled within the housing, this housing mounting a brake key operable by the holding hand for momentarily blocking the portion of the leash located outside the holding at a desired length with a brake lock mechanism for holding the brake key in the locking position. This brake lock mechanism comprises a two-armed lever arranged to be moved between two positions on the housing reachable by the same finger/thumb of the holding hand, the handling of this pivoted lever occurring in an ergonomically optimal manner.

  • Patent number: 5483926
    Abstract: The invention relates to a retractable animal leash assembly including a housing suitable for being held in one hand, an unwindable leash arranged partially coiled within the housing, a brake which is operable by the holding hand for momentarily blocking the portion of the leash located outside the housing at a desired length and a brake lock mechanism for holding the brake in the blocking position. The brake lock mechanism is activated with operating levers arranged in two positions on the housing reachable by the holding hand. Thus the housing can be held in either the left or the right hand without degradation of function and the prolonged switch may be easily and quickly operated by the holding hand or its fingers.
