  • Patent number: 4957055
    Abstract: An improved fender maintains separation between a vessel, such as a pleasure boat, and a wharf to which the vessel is moored. The fender utilizes an elastic shock absorber element and a thrust rod that is connected at one end to the vessel and at the other end to the elastic shock absorber element. The elastic shock absorber element is held by a two-armed support structure at some distance away from the top of the wharf. The support structure prevents the thrust rod from receiving forces from sources other than the vessel and the elastic shock absorber element.

  • Patent number: 4261279
    Abstract: A fender maintains separation between a vessel, such as a pleasure boat, and a wharf to which the vessel is moored. The fender utilizes a thrust rod, one end of which is connected to the vessel. In a preferred embodiment, the other end of the thrust rod is linked to one end of each of two elastic shock absorber elements. The other ends of each of such shock absorber elements are capable of being affixed to the wharf. The embodiment also provides wheels at the wharf end of the thrust rod to reduce friction between the thrust rod end and the wharf.
