  • Patent number: 4136632
    Abstract: A fender for marine use is described having an outer flexible shell forming a chamber, compressible buoyant material within the chamber and a mooring fitting connected to the shell to secure the fender. The shell is composed of a single piece of homogeneous elastomeric material, having a thickened annularly shaped lip extending around an orifice providing access to the chamber for filling. The mooring fitting is formed with a cavity and the lip of the shell is captured within this cavity to secure the fitting to the shell, so that the shell permits stretching of the fender when it is pinned between two objects while a tensile force is applied to said mooring fitting. The mooring fitting captures the lip without compressing it, so that the fitting may swivel with respect to the shell while still securing the shell from separating from said fitting.
