  • Patent number: 5083522
    Abstract: A swimming harness for holding a swimming at a selected location in a body of water such as a swimming pool and giving the swimmer freedom of swimming movement. The swimming harness comprises an elongated integral braided cord having an inner end which is secured to a fixed object located directly adjacent the swimming pool and an outer end which is connected, such as by a belt, to the swimmer. The elongated integral braided cord includes an enlarged section within which is mounted a stretchable resilient solid cord. The resilient cord functions to stretch to substantially eliminate any jerking movements produced by the swimmer during the swimming motion. The enlarged section of cord that surrounds the resilient solid cord is capable of being expanded a limited amount thereby functioning as a stretch limiter for the resilient solid cord.
