Abstract
Abstract Floating dock structure comprising two pairs of channel sections rigidly connected to define a rectangular support frame. A plurality of floating containers are arranged below the rectangular frame for enabling the dock to float and are constrained in place by cross angle sections. The containers support at least a sheet of marine plywood above which a plurality of footboards are provided. The dock structure has a relative service gangway of rectangular structure. The frame of the gangway comprises two pairs of angle sections above which there are located a sheet of marine plywood, this latter supporting a plurality of footboards. The gangway rests at its one end on the dock and is provided at the other end with means for coupling to the dry land.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
302 words
A floating dock structure comprising a first pair of spaced apart parallel channel sections extending lengthwise to the dock structure and having sea facing and land facing ends, a second pair of spaced apart parallel channel sections extending widthwise to the dock structure, one of said widthwise extending channel sections rigidly connecting said sea facing ends of said first pair of lengthwise extending channel sections and the other of said widthwise extending channel sections rigidly connecting the land facing ends of said lengthwise extending channel sections, thereby to form a rectangular frame delimiting a closed perimeter, each of said channel sections having a web and channel flanges on the opposite edges of said web, a number of floating members within said perimeter, each of said floating members consisting of a container having a top and a rectangular bottom wall and side walls arranged to defining a rectangular crosssection of said container, said side walls of the container having a flange formation on the outer surface thereof in an intermediate position between said top and said bottom wall and extending substantially parallel to said bottom wall, angle sections extending crosswise to said rectangular frame, said angle sections having each angle flanges extending transverse to each other, one of said angle flanges being arranged to cooperate with one side wall of said container above said flange formation thereof and having a lower edge thereof abutting against said flange formation, and the other of said angle flanges being arranged to cooperate with one of said channel flanges, at least one of said angle flanges being selectively fixed to said side wall and said channel flanges, thereby to form a rigid structure consisting of said rectangular frame and said containers, a plurality of covering members on said containers forming a walkway surface for the floating dock.
Claim 2
Dependent Claim
302 words
A floating dock structure comprising a first pair of spaced apart parallel channel sections extending lengthwise to the dock structure and having sea facing and land facing ends, a second pair of spaced apart parallel channel sections extending widthwise to the dock structure, one of said widthwise extending channel sections rigidly connecting said sea facing ends of said first pair of lengthwise extending channel sections and the other of said widthwise extending channel sections rigidly connecting the land facing ends of said lengthwise extending channel sections, thereby to form a rectangular frame delimiting a closed perimeter, each of said channel sections having a web and channel flanges on the opposite edges of said web, a number of floating members within said perimeter, each of said floating members consisting of a container having a top and a rectangular bottom wall and side walls arranged to defining a rectangular crosssection of said container, said side walls of the container having a flange formation on the outer surface thereof in an intermediate position between said top and said bottom wall and extending substantially parallel to said bottom wall, angle sections extending crosswise to said rectangular frame, said angle sections having each angle flanges extending transverse to each other, one of said angle flanges being arranged to cooperate with one side wall of said container above said flange formation thereof and having a lower edge thereof abutting against said flange formation, and the other of said angle flanges being arranged to cooperate with one of said channel flanges, at least one of said angle flanges being selectively fixed to said side wall and said channel flanges, thereby to form a rigid structure consisting of said rectangular frame and said containers, a plurality of covering members on said containers forming a walkway surface for the floating dock.
Claim 3
Dependent Claim
52 words
A floating dock structure according to claim 1, wherein said covering members include a lid on top of each of said containers for hermetically sealing the same, a plurality of sheets of marine plywood on said lids and a plurality of footboards with through holes, disposed side by side above said sheets.
Claim 4
Dependent Claim
51 words
A floating dock structure according to claim 1, wherein said lengthwise extending channel sections have their flanges projecting towards the outside, the structure further comprising fenders of elastic material and of substaNtially cylindrical configuration arranged along said lengthwise extending channel sections and having a portion thereof received between the said flanges.
Claim 5
Dependent Claim
34 words
A floating dock structure as claimed in claim 1, further comprising spaced apart sleeve members fixed on said channel sections and bars inserted into said sleeve members for hinged coupling to analogous dock structure.
Claim 6
Dependent Claim
63 words
A floating dock structure according to claim 1, wherein said widthwise extending channel sections are arranged with their channel flanges facing inwards and wherein at least the web of the channel section arranged at said sea facing end having screw means for a face to face connection with an analogous web of a widthwise extending channel section of an adjoining floating dock structure.
Claim 7
Dependent Claim
161 words
A floating dock structure according to claim 1, further comprising a service gangway having one end thereof hinged to an anchor member fixable on the ground, and the other end thereof supported on a portion of said walkway surface, said gangway comprising a rectangular frame having sides made of angle sections, at least one pair of stiffening T-sections disposed transverse to the longitudinal extension of said gangway, at least one sheet of marine plywood disposed above said T-sections and angle sections, and a plurality of footboards comprising through holes and disposed side by side above said sheet, said gangway having said other end thereof resting on said portion of walkway surface and including a strip of checkered metal and fender elements interposed between said strip and said walkway surface portion, said one end of the service gangway having a sleeve member fixed to the angle section frame thereof and a bar inserted therein for a hinged connection with said anchor member.
