Abstract
Abstract A novel marine dock section adapted to be supported by flotation units or posts is described. A pair of horizontally spaced apart, upright, prefabricated truss-like frameworks, each comprising a pair of longitudinal tubular members preferably of rectangular cross-section secured a spaced distance apart by a plurality of vertical tubular struts extending through and double swaged into the longitudinal tubular members, are joined together by a plurality of cross members to form a planar rectangular frame which supports a wood plank decking.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
A dock section comprising, in combination: a pair of horizontally spaced apart elongated prefabricated frameworks, each framework comprising a pair of parallel, longitudinal, upper and lower tubular members rectangular in cross section secured a spaced distance apart by a plurality of equispaced vertical tubular struts circular in cross section which extend through and are double swaged into the longitudinal tubular members for rigid connection to the longitudinal tubular members, a plurality of cross members rigidly interconnecting said elongated prefabricated frameworks to form a planar, rectangular frame, said cross members each comprising an upper angle and a lower planar bar secured together by vertical struts whereby said upper angle provides a transverse support flange, a circular clamp extending from each of the upper angle and lower planar bar at each end of each cross member for encircling a vertical tubular strut for securement thereto, and wood plank decking substantially coextensive with said rectangular frame seated on the upper angle transverse flanges, and means for securing said decking to said flanges.
Claim 2
Dependent Claim
169 words
A dock section comprising, in combination: a pair of horizontally spaced apart elongated prefabricated frameworks, each framework comprising a pair of parallel, longitudinal, upper and lower tubular members rectangular in cross section secured a spaced distance apart by a plurality of equispaced vertical tubular struts circular in cross section which extend through and are double swaged into the longitudinal tubular members for rigid connection to the longitudinal tubular members, a plurality of cross members rigidly interconnecting said elongated prefabricated frameworks to form a planar, rectangular frame, said cross members each comprising an upper angle and a lower planar bar secured together by vertical struts whereby said upper angle provides a transverse support flange, a circular clamp extending from each of the upper angle and lower planar bar at each end of each cross member for encircling a vertical tubular strut for securement thereto, and wood plank decking substantially coextensive with said rectangular frame seated on the upper angle transverse flanges, and means for securing said decking to said flanges.
Claim 3
Dependent Claim
132 words
A dock section comprising, in combination: a pair of horizontally spaced apart elongated prefabricated frameworks, each framework comprising a pair of parallel, longitudinal upper and lower tubular members rectangular in cross section secured a spaced distance apart by a plurality of equispaced vertical tubular struts circular in cross section which extend through and are double swaged into the longitudinal tubular members for rigid connection to the longitudinal tubular members, a plurality of cross members comprising a plurality of equispaced transverse tubular struts circular in cross section which extend through and are double swaged at each end into upper longitudinal tubular members between the vertical tubular struts rigidly interconnecting said elongated prefabricated frameworks to form a planar, rectangular frame, and wood plank decking substantially coextensive with said rectangular frame superimposed and seated thereon.
Claim 4
Dependent Claim
132 words
A dock section comprising, in combination: a pair of horizontally spaced apart elongated prefabricated frameworks, each framework comprising a pair of parallel, longitudinal upper and lower tubular members rectangular in cross section secured a spaced distance apart by a plurality of equispaced vertical tubular struts circular in cross section which extend through and are double swaged into the longitudinal tubular members for rigid connection to the longitudinal tubular members, a plurality of cross members comprising a plurality of equispaced transverse tubular struts circular in cross section which extend through and are double swaged at each end into upper longitudinal tubular members between the vertical tubular struts rigidly interconnecting said elongated prefabricated frameworks to form a planar, rectangular frame, and wood plank decking substantially coextensive with said rectangular frame superimposed and seated thereon.
