Fender For Floating Vessel
US Patent:
4957055, Sep 18, 1990
Filed:
Jun 27, 1989
Appl. No.:
7/372291
Inventors:
Leonard W. Johnson - Amesbury MA
International Classification:
B63B 5902
US Classification:
114219
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.
Fender For Floating Vessel

Filed:
Jun 12, 1978
Appl. No.:
5/914344
Inventors:
Leonard W. Johnson - Amesbury MA
International Classification:
B63B 5902
US Classification:
114220
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.
