Abstract
Description
[0001] The following problems occur with the normal use of dog leashes with a retractable function. 1. If the dog suddenly runs off due to the carelessness of the leash owner and reaches the end of the leash, the dog will have accumulated a great deal of kinetic energy, depending on the dog's mass and acceleration. This energy is then abruptly released into the leash when the dog reaches the end of the leash. 2. If the dog suddenly starts running, it takes a moment to press the leash lock button. Depending on the dog's mass and acceleration, the dog has already accumulated a great deal of kinetic energy. This energy is then released abruptly into the leash when the leash reaches its end stop.
[0002] Both pose a high risk of injury and danger, both for the leash owner and for others. Either the leash owner manages to hold onto the leash despite the kinetic energy and is injured, or they fail to hold onto the leash and the leash is ripped from their grasp. The dog then runs off uncontrollably. 3. Another problem arises when the carabiner of an extended leash is unhooked from the dog and the dog is released. This can happen, for example, if the dog has wrapped itself around a tree with the leash and the leash holder or another person then lets go. If the leash holder then forgets to press the locking button, the carabiner will retract uncontrollably and at high speed into the retractor. This also poses a high risk of injury to the leash holder and other people in the vicinity.
[0003] These problems are solved with the brake unit for dog leashes mentioned in claim 1.
[0004] The retractable dog leash is equipped with a dynamic brake. This adjusts its braking performance depending on the speed at which the leash is unwound or retracted.
[0005] The higher the speed of the line, the higher the braking power.
[0006] Regarding points 1 and 2: The speed-dependent braking power of the dynamic brake allows the dog to generate significantly reduced kinetic energy. This significantly reduces the potential for injury and danger. If the dog is inattentive, the brakes will alert the owner to the dog, allowing them to react in a controlled manner before the dog reaches the end of the leash.
[0007] Regarding point 3: Due to the speed-dependent braking performance of the dynamic brake, the carabiner can only reach a significantly reduced speed when recoiling. This also significantly reduces the potential for injury.
Claims
