Abstract

Abstract A support structure in combination with a flotation cell adapted to support a floatable marine dock or the like, wherein the cell comprises a buoyant, rectangular, hollow, box-shaped housing formed as a thin-walled float provided with oppositely disposed, threaded bushings molded therein in such a manner as to threadably receive a continuously threaded rod that extends across the entire width of the float, thereby rigidly interconnecting the oppositely disposed side walls thereof. The rods are positioned to protrude on each side of the float to additionally support and mount the dock frame structure, whereby stresses placed on the dock are transmitted to the rod and absorbed thereby.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 161 words
A support structure for a floatable marine dock comprising: a floating cell defining a sealed, buoyant housing having end walls, a top wall, a bottom wall and side walls formed from a high-density-polyethylene material, wherein said side walls include a plurality of inwardly protruding jackets; a plurality of support rods, each continuously threaded throughout the length thereof, each of said rods being threaded through oppositely aligned bushings, thereby forming a rigid structure therebetween, wherein each rod projects outwardly from said side walls thereof; sealing means provided by said jackets for sealing engagement with said rods to prevent leakage within said cell; a plurality of threaded bushings integrally formed within the side walls and molded within said jackets thereof, said bushings in one of said side walls being oppositely disposed to said bushings in said other side wall, and wherein opposite bushings are axially aligned with each other; and a dock-frame structure demountably attached to said projecting ends of said support rods.
Claim 2
Dependent Claim 161 words
A support structure for a floatable marine dock comprising: a floating cell defining a sealed, buoyant housing having end walls, a top wall, a bottom wall and side walls formed from a high-density-polyethylene material, wherein said side walls include a plurality of inwardly protruding jackets; a plurality of support rods, each continuously threaded throughout the length thereof, each of said rods being threaded through oppositely aligned bushings, thereby forming a rigid structure therebetween, wherein each rod projects outwardly from said side walls thereof; sealing means provided by said jackets for sealing engagement with said rods to prevent leakage within said cell; a plurality of threaded bushings integrally formed within the side walls and molded within said jackets thereof, said bushings in one of said side walls being oppositely disposed to said bushings in said other side wall, and wherein opposite bushings are axially aligned with each other; and a dock-frame structure demountably attached to said projecting ends of said support rods.
Claim 3
Dependent Claim 40 words
A support structure as recited in claim 1, wherein said floatation cell includes: a plurality of threaded bushings molded within each end wall thereof; and a threaded stud member threadably supported in each bushing mounted in said end walls thereof.
Claim 4
Dependent Claim 38 words
A support structure as recited in claim 2, wherein said floatation cells includes a sealed, buoyant housing formed in a substantially-box-like configuration having a plurality of integrally formed rib members, whereby additional rigidity is provided to said cell.
Claim 5
Dependent Claim 58 words
A support structure as recited in claim 3, wherein said dock-frame structure includes: a pair of side-frame members secured to said support rods; an end-frame member secured to said stud members; and a decking attached to said frame members, wherein a plurality of cells are juxtapositioned in an end-to-end manner, each cell being secured to said side-frame members.
