  • Shock absorber for attachment to a dog leash
    Patent number: 7530334
    Abstract: The body of the shock absorber is made of lightweight flexible resilient tubular polymer material which will not cause injury when struck by it. The body has a stop in each end and two compression springs within the tubular body between the stops. Tension cables are attached to the compression springs and do not pneumatically engage within the tubular polymer body and extend out of the body and respectively carry a snap hook for attachment to a dog collar and a ring for attachment to a dog leash. Pull on the tension members causes compression of the springs to reduce shock-loading on the dog walker. After the springs are pulled solid, the resiliency of the body continues to absorb shock.
