Abstract
Abstract A nautical boat mooring apparatus which includes a rigid open-ended tubular member which forms a longitudinal open-ended chamber therein, a piston assembly providing a piston slideably positionable within the longitudinal open-ended chamber and a rod portion, the rod portion being extensible out of one end of the longitudinal chamber, a first spring for urging the piston toward the second end of the tubular member, a second spring for urging the piston toward the first end of the tubular member, a first coupling device for removably affixing the first end of the tubular member to a supporting surface, and a second device for removably affixing another portion of the piston assembly to a nautical vessel. Both coupling devices employ ball and socket arrangements to permit the apparatus to accommodate yaw, roll and pitch of the vessel.

Claim 1
Independent Claim
382 words
A nautical mooring apparatus comprising a rigid open-ended tubular member having a first end and a second end, said tubular member forming a longitudinal open-ended chamber therein, a piston assembly including a piston and a rod portion fixedly secured thereto, said piston slideable within said longitudinal chamber, said rod portion coaxially extensible out of said longitudinal chamber through an opening located in said second end of said tubular member, first means for urging said piston toward said second end of said tubular member, second means for urging said piston toward said first end of said tubular member, first means for affixing said first end of said tubular member to a supporting surface, said first affixing means including a first rod rotatably affixed on a first end thereof to a first bracket, said first bracket for affixment to said supporting surface, the second end of said first rod providing a ball-shaped element, and a first cap fixedly secured to said tubular member adjacent said first end thereof, said first cap providing a capturing chamber therein, said capturing chamber capturing said ball-shaped element and permitting angular movement of said second end of said first rod relative to said supporting surface, and second means for affixing said rod portion of said piston assembly to a nautical vehicle, said second affixing means including a second bracket for affixment on one end thereof to said nautical vehicle, a second rod, one end of said second rod pivotally removably affixed to said bracket the other end of said second rod affixed to a ball, a cap, said cap having a hemispherical cavity and said cavity extending to an external surface of said cap, said cap secured to the free end of said rod portion, said second bracket having an aperture therein, a plate, said plate fixedly secured to said one end of said second rod, said plate having circular marginal edges, a sheet-like member, said sheet-like member slideably affixed to said second bracket at a plane normal to the longitudinal axis of said aperture, whereby said plate is rotatably locked into said aperture when said sheet-like member is disposed partially juxtaposed with said plate, wherein said first and said second affixing means permits movement of the longitudinal axis of said tubular member angularly relative to a horizontal plane.
Claim 2
Dependent Claim
382 words
A nautical mooring apparatus comprising a rigid open-ended tubular member having a first end and a second end, said tubular member forming a longitudinal open-ended chamber therein, a piston assembly including a piston and a rod portion fixedly secured thereto, said piston slideable within said longitudinal chamber, said rod portion coaxially extensible out of said longitudinal chamber through an opening located in said second end of said tubular member, first means for urging said piston toward said second end of said tubular member, second means for urging said piston toward said first end of said tubular member, first means for affixing said first end of said tubular member to a supporting surface, said first affixing means including a first rod rotatably affixed on a first end thereof to a first bracket, said first bracket for affixment to said supporting surface, the second end of said first rod providing a ball-shaped element, and a first cap fixedly secured to said tubular member adjacent said first end thereof, said first cap providing a capturing chamber therein, said capturing chamber capturing said ball-shaped element and permitting angular movement of said second end of said first rod relative to said supporting surface, and second means for affixing said rod portion of said piston assembly to a nautical vehicle, said second affixing means including a second bracket for affixment on one end thereof to said nautical vehicle, a second rod, one end of said second rod pivotally removably affixed to said bracket the other end of said second rod affixed to a ball, a cap, said cap having a hemispherical cavity and said cavity extending to an external surface of said cap, said cap secured to the free end of said rod portion, said second bracket having an aperture therein, a plate, said plate fixedly secured to said one end of said second rod, said plate having circular marginal edges, a sheet-like member, said sheet-like member slideably affixed to said second bracket at a plane normal to the longitudinal axis of said aperture, whereby said plate is rotatably locked into said aperture when said sheet-like member is disposed partially juxtaposed with said plate, wherein said first and said second affixing means permits movement of the longitudinal axis of said tubular member angularly relative to a horizontal plane.
Claim 3
Dependent Claim
33 words

Claim 4
Dependent Claim
33 words
A nautical mooring apparatus as claimed in claim 1, wherein said second urging means comprises a second helical compression spring disposed within said longitudinal chamber between said second end thereof and said piston.
Claim 5
Dependent Claim
20 words
A nautical mooring apparatus as claimed in claim 3, wherein said rod portion extends through said second helical compression spring.
Claim 6
Dependent Claim
15 words
