A modular interlocking flotation assembly for selective creation of a raft includes a plurality of shells. Each of a plurality of couplers is coupled to a respective shell so that the shells of the plurality of shells are selectively interconnectable in a substantially planar configuration. The plurality of shells thus interconnected is configured to function selectively a raft and a portable dock.

A floating module includes an upper half and a lower half. The upper half includes one edge from which a flange extends downwardly, while the lower half includes an opposite edge that includes an upwardly facing flange. Modules can be interconnected to one another by engaging the upper flange from one with the lower flange from another. A cavity and channels are formed in the lower surface of the module such that water will become entrapped in the cavity and channels when the platform is placed in water. Through use of one way check valves positioned in fluid communication with the cavity and channels, a hydro-lock is formed that prevents the water from escaping the cavity and channels while it is placed in water.

A floating dam or island is provided by pre-fabricating modular hollow bodies. A first group of modular bodies is laid floating on a water surface, positioning the modular bodies in mutual side-to-side arrangement so as to delimit therebetween intermediate gaps within which the reinforcing rods are protruding. A first concrete casting is performed into the gaps and over the modular bodies so as to render them mutually joined. A second group of modular bodies is then laid over the first group and a second concrete casting is performed in order to join the first and second group together. Additional groups of modular bodies are laid and further concrete castings are performed up to obtaining a monolithic block having a desired floating dam or island configuration.

A combination float and bracket assembly for a floating structure that includes a float body made of foam with a plurality of transversely aligned L-shaped brackets that extend upward from the float body's top surface. Each bracket includes a horizontal flange and a vertical flange and the foam body is made of closed-cell foam. During manufacturing, a plurality of bracket cutouts is formed in the top surface of the float body. A brackets is then inserted into each bracket cutout. The bracket's vertical flanges extends upward above the top surface. Connectors are used to attach the vertical flanges to a frame member. In one embodiment, a transversely aligned frame member void area is formed in the float body adjacent to the vertical flange. The void area receives the frame member that extends over the top surface of the float body and attaches to the vertical flange. Also disclosed is a floating structure that includes a frame attached to a plurality of float and bracket assemblies.

A floating dock hinging latch releasably interconnects a pair of floating dock sections in an adjoined spaced relation for relative hinging motion. The floating dock hinging latch includes a pair of female latch portions secured to the side of one floating dock section and a pair of male latch portions secured to the side of the other floating dock section. The female latch portions and male latch portions are releasably engaged with one another to hingedly connect the floating dock sections by moving the floating dock sections toward one another across the surface of the water.

A dock stabilizing pile guide device includes a frame attached to a floating dock and enclosing a respective piling. The frame carries a plurality of rollers that rotatably interengage the piling and guide the dock upwardly and downwardly along the piling as the depth of the underlying water changes.

A composite floating dock system comprised of one or more dock float components, with each dock float component having a dock frame and one or more floats attached thereto, with each of the dock float components constructed of fiberglass reinforced plastic into a single monolithic unit, and being ballasted with encased concrete.

A movable platform adjacent to a stationary platform and operable between a raised position forming a part of a deck surface and a lowered position at least partially submerged in the body of water. A landing section and walkway section included in the movable platform. A lever arm carried by the landing section and extending underneath the walkway section, wherein the lever arm engages a bottom side of the walkway section when the movable platform is in the raised position, and the lever arm disengages from the walkway section when the movable platform is in the lowered position. A floatation unit disposed on the bottom side of the landing section. An air pump unit carried by the stationary platform, wherein the air pump unit channels air into and out of the floatation unit to change the buoyancy of the floatation unit to raise and lower the movable platform.

A pile guide has a collar with a void therein. A planar flange extends from a side of the collar. A first guide and a second guide form opposing guides constructed and arranged for receiving the planar flange of the pile guide therein. The planar flange is in a slidable relationship within the opposing guides, and the bracket is constructed and arranged for mounting to a dock. The opposing guides pivot relative to the dock during installation and allow pivoting of the pile guide relative to the dock or other mounting. The distance and angle of the collar relative to the dock or other mounting can be adjusted to accommodate for positioning of pile guides due to positioning of piles relative to a dock or other structure.

A modular floating platform connector includes a connecting unit with a hollow center chamber that has one or more inside diameters. The chamber may have wall surfaces to secure components to modular floating platforms. The connector may further incorporate one or more external features such as a collar and retaining ribs that engage with the connecting tabs on modular floating platform float modules to securely hold the float modules together and to retain attachment members of accessories, fixtures, structures and other components to modular floating platforms.
