ABSTRACT:
The invention provides a manually held leash, lead, line or the like for large and strong animals which incorporates a shock absorbing device for diminishing the effect of the force or strain transmitted when the animal suddenly and forcibly pulls, lunges, bolts, jumps, etc. The shock absorber incorporated resilient shock absorbing elements automatically operative to oppose the force exerted by the animal and diminish its effect on the manually held leash. The device is constituted of a pneumatic cylinder the piston of which is connected to the animal and normally is retained in a retracted position by a compressive spring against which the animal pulls. In addition to the restraining force imposed by the spring, compressed air also is utilized to absorb the shock of the animal's pulling force. A command sound, such as a recorded voice, buzzer, or the like, actuated under controlled circumstances and operative to order the animal to halt or obey, may be included. The shock absorbent leash of the invention reduces the potential for injury to a person holding the leash, in the event the animal exerts a sudden and substantial force thereon. The invention has a variety of other applications where connectors joining two separate entities, bodies or objects are subjected to sudden force or strain. Examples of such connectors are vehicle tow lines, tie down lines for aircraft, tent guy ropes, mooring lines for boats, swing chains, and the like.
