Abstract

Abstract A marine float structure comprising a float unit, a deck unit, and a framework of connecting members to which the float and deck units are secured. Both the float and deck units are formed by rotationally molding a suitable high strength, durable polymeric material such as cross linked, high density polyethylene. The float and deck units are single piece, hollow, buoyant, rectangular box shaped housings differing in their dimensions only in that the depth of the deck unit is substantially less than that of the float unit. The top wall of both the float and deck units is flanged with respect to the end and side walls. The two units are secured to the connecting members sandwiched between the flanges by means extending through apertures in the flanges. The float unit is preferably filled with a polyurethane or similar foam material. A plurality of marine float structures are interconnected to form a marine floating dock.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 160 words
A marine float structure comprising a one piece, molded hollow, buoyant, rectangular box-shaped float unit of high strength, durable polymeric material, said float unit having end, side, top and bottom walls, the top wall of which is flanged at a 90° angle at least at one point with respect to each side and end wall; a one piece, molded hollow, buoyant, rectangular box-shaped deck unit of high strength, durable polymeric material, said deck unit having end, side, top and bottom walls, the dimensions of which are essentially the same as those of the float unit except that the height of said side walls is substantially less than that of the float unit, the top wall of the deck unit being flanged at a 90° angle to the side and end walls thereof; a framework of connecting members sandwiched between the flanges of the float and deck units; and means connecting the float and deck units to the framework connecting members.
Claim 2
Dependent Claim 160 words
A marine float structure comprising a one piece, molded hollow, buoyant, rectangular box-shaped float unit of high strength, durable polymeric material, said float unit having end, side, top and bottom walls, the top wall of which is flanged at a 90° angle at least at one point with respect to each side and end wall; a one piece, molded hollow, buoyant, rectangular box-shaped deck unit of high strength, durable polymeric material, said deck unit having end, side, top and bottom walls, the dimensions of which are essentially the same as those of the float unit except that the height of said side walls is substantially less than that of the float unit, the top wall of the deck unit being flanged at a 90° angle to the side and end walls thereof; a framework of connecting members sandwiched between the flanges of the float and deck units; and means connecting the float and deck units to the framework connecting members.
Claim 3
Dependent Claim 27 words
A marine float structure according to claim 1 in which the framework comprises connecting members that extend along the sides and end walls of the float unit.
Claim 4
Dependent Claim 30 words
A marine float structure according to claim 1 in which a raceway is provided between the top wall of the float unit and the bottom wall of the deck unit.
Claim 5
Dependent Claim 24 words
A marine float structure according to claim 1 in which the top wall of the deck unit is textured to provide a non-slip surface.
Claim 6
Dependent Claim 20 words
A marine floating dock comprising a plurality of interconnected marine float structures, said marine float structures according to claim 4.
