  • Patent number: 4471854
    Abstract: A flexible embarkation-debarkation marine ladder having a pair of flexible wire rope suspension members. A plurality of steps are secured to the suspension members at spaced intervals. The steps include a pair of ears. The opposite ends of the rungs are secured to the ears in spaced relationship. Each ear includes a tubular sleeve extending perpendicularly to and in aligned relationship to the spacing between the rungs. The suspension member extends coaxially through the sleeves. A plurality of constrictible annular stops are fixed to the suspension member at the opposite ends of the sleeves to lock the steps to the suspension member in parallel, spaced relationship. In another form, the marine ladder suspension members are formed of a pair of fiber ropes. The fiber ropes extend through rectangular tubular sleeves which are fixedly secured to the ears as by welding.

  • Patent number: 4376419
    Abstract: A marine fender structure including a plurality of rollers rotatably mounted on a pair of flexible elongated supports. Horizontal spacers are provided at vertically spaced intervals along these supports to maintain the supports in horizontally spaced relationship whereby the rollers may freely roll along the side of the marine structure for facilitated functioning thereof in serving as fenders. Retaining structure is provided for retaining the rollers and spacer elements in association with the support elements in groups of a pair of rollers and one of the spacer elements at vertically spaced positions along the fender structure. In the illustrated embodiment, the spacer elements define rungs permitting the fender structure to further serve as a ladder.
