Abstract
A barge cover assembly includes at least one first cover section and at least one end cover section. The first cover section includes a stairway that is within a rib profile. The first cover section also includes a door that protrudes only slightly above an upper surface such that the door is not impacted when cover sections are stacked. The door opening is approximately four feet by eight feet such that a standard-sized sheet of a material such as plywood can be used to cover the door opening in the event that a door has been removed from the cover section. The end cover section has an end with a stepped rib/valley structure wherein successive ribs and valleys form steps of the stairway.
Claims19
A cover assembly for a barge comprising:
- a first cover section;
- the first cover section having at least two ribs, each of the ribs having a rib profile, the first cover section further having a stairway formed between the two ribs such that the stairway is contained within the rib profile of the two ribs;
- and
- a second cover section sized and shaped to be fitted to the first cover section.

A cover assembly for a barge comprising:
- a first cover section having an arched cross-sectional shape, a rib formed therein, and an upper surface;
- the first cover section having an opening formed therein, the first cover section further including a door movably attached to the first cover section, the door being movable to a first position in which the opening is substantially covered and movable to a second position in which the opening is substantially uncovered, the door being sized and shaped to substantially cover the opening and protrude less than approximately one inch over the upper surface in the first position;
- and
- a second cover section sized and shaped to be fitted together with the first cover section,
- wherein the door has a depression formed therein, the depression being positioned and sized to receive the rib when the door is in the second position such that a portion of the door is below a top surface of the rib.

A cover assembly for a barge comprising:
- a first cover section;
- and
- a first end cover section, the first end cover section having a center axis that is parallel to a longitudinal axis of a barge when the first end cover section is installed on a barge, the first end cover section having an arched cross-sectional shape and a proximal end and a distal end, the proximal end being sized and shaped to be fitted together with the first cover section, the distal end comprising a plurality of alternating ribs and valleys, the ribs and valleys having heights such that each rib is lower than a preceding valley and higher than a subsequent valley and each valley is higher than a subsequent rib and lower than a preceding rib, each of the alternating ribs and valleys having a depression formed therein to define a step.

- and
- an end cover section, the end cover section having a center axis that is parallel to a longitudinal axis of a barge when the first end cover section is installed on a barge, the end cover section having an arched cross-sectional shape and a proximal end and a distal end, the proximal end being sized and shaped to be fitted together with the first cover section, the distal end comprising a plurality of alternating end cover section ribs and valleys, the end cover section ribs and valleys having heights such that each end cover section rib is lower than a preceding valley and higher than a subsequent valley and each valley is higher than a subsequent rib and lower than a preceding rib, each of the alternating end cover section ribs and valleys having a depression formed therein to define a step;
- each of the first cover section ribs and end cover section ribs being compound-curved.

A cover assembly for a barge comprising:
- a first cover section having an arched cross sectional shape, the second cover section being sized and shaped to be fitted over an opening of a barge, the first cover section having an opening formed therein;
- and
- a second cover section having an arched cross sectional shape, the second cover section being sized and shaped to be fitted over the opening of the barge;
- wherein the first cover section has an opening formed therein, the first cover section further comprising a door connected to the first cover section by a hinge such that the door is movable between a first position in which the door substantially covers the opening and a second position, the door being sized and shaped such that the second cover section will not impact the door when the door is in the first position and the second cover section is stacked on the first cover section even if the first and second cover sections are not aligned.
