Marine Dock Suction Float Element
A floating marine dock employs a plurality of spaced-apart suction float elements. Each element includes a foam filled plastic shell having a plurality of suction pockets that extend vertically upwardly through and beyond a bottom wall section of the shell to an upper end within the shell. When a load is placed on the dock or walkway, the buoyant float element produces a low pressure or vacuum space within each pocket and a resultant suction that forcefully adheres the float elements and dock securely to the underlying water
This application claims the benefit of application Ser. No. 63/323,233, filed Mar. 24, 2022.
FIELD OF THE INVENTIONThis invention relates to a float element for supporting a marine dock or walkway upon a body of water. More particularly, the invention relates to a suction float element that more securely and stably supports a floating dock or walkway.
BACKGROUND OF THE INVENTIONFloating marine docks are beneficial for use in various applications and environments. Such docks can be utilized in both deep and shallow water. Floating docks are also practical for use on shoreline locations that feature fluctuating tides and water levels. The floating dock does not have to be embedded in the bottom of the sea, lake or other body of water on which the dock is located. This can alleviate potential engineering, environmental and regulatory concerns, which, in turn, can significantly reduce the cost of dock installation. Moreover, the desired configuration of the dock can be selected, rearranged and adjusted much more easily than a conventional fixed dock.
Conventional floating docks and walkways typically employ buoyant floats to support a platform or other walking surface on the water. A significant problem exhibited by virtually all such products is that they can be quite unstable and exhibit a serious risk of tipping. Instability is particularly great when the water is rough or choppy, during inclement weather, or when a heavy or imbalanced load is placed upon the dock or walkway. In addition, the known floats used in current floating docks and walkways can be tedious and time consuming to disassemble, rearrange and reconfigure. Most cannot be readily and versatilely adapted for use on docks and walkways having different widths and longitudinal spans or alternative configurations.
SUMMARY OF THE INVENTIONIt is a therefore an object of this invention to provide an improved float element for floating marine docks and walkways, which exhibits significantly better stability and a reduced risk of tipping than structures employing conventional float elements.
It is a further object of this invention to provide a marine dock float element that features a suction or vacuum interengagement with the underlying body of water so that dock stability is significantly improved and the danger of accidental tipping is reduced, especially in conditions of rough water, inclement weather and when heavier and/or unbalanced loads are placed on the dock.
It is a further object of this invention to provide a suction float element for marine docks and walkways, which element maintains a lower and more stable freeboard than conventional marine floats.
It is a further object of this invention to provide a marine float element that may be quickly and conveniently adjusted to support docks and walkways having a variety of different widths, longitudinal spans and/or configurations.
This invention features a suction float element for supporting a floating marine dock or walkway on a body of water. The float element includes an exterior shell composed of plastic or other buoyant material and filled with a buoyant foam. The shell includes a top wall section, an opposing bottom wall section, and a side wall section that interconnects the top and bottom wall sections. The side wall section includes a plurality of vertical recesses that extend between the top and bottom wall sections. The bottom wall section includes a plurality of concave peripheral openings that respectively correspond to and communicate with lower ends of the vertical recesses in the side wall section. The top wall section covers the opposite upper ends of the vertical recesses. The upper wall section includes a plurality of slots that correspond to and communicate with the upper ends of the respective vertical recesses. Each slot receives a respective connector to secure the float element to a frame of the deck or walkway. The bottom wall section further includes a plurality of suction pockets that extend vertically upwardly from the bottom wall section and terminate intermediate the bottom and top wall sections. The float element depends from and is supported by the frame and the bottom wall section of the float element is engaged by an underlying body of water such that when a load is applied to the dock or walkway, the buoyancy of the float element produces suction within the suction pockets, which causes the float element to be gripped by the underlying water.
In a preferred embodiment, the top and bottom wall sections of the shell have respective rectangular configurations. The side wall section may include four side segments, each side segment extending between a pair of corresponding upper and lower edges of the top and bottom wall sections. Each side wall segment may exhibit a narrowing taper extending from the top wall section to the bottom wall section such that the top wall section includes a width and length that are greater than a width and length of the bottom wall section.
The bottom wall section of the shell may include four suction pockets. Each suction pocket may include a pair of elongate and parallel sides that are interconnected by an opposing pair of arcuate ends. Each suction pocket may extend between the bottom wall section and a flat distal end of the suction pocket situated approximately midway between an upper surface of the top wall section and a lower surface of the bottom wall section.
A pair of vertical recesses may be formed in each segment of the side wall section. Each vertical recess may include a semicylindrical concave shape. Each opening in the bottom wall section may have a corresponding concave shape. The top wall section may include semicircular shaped peripheral regions that correspond with respective semicylindrical vertical recesses. Each slot in the top wall section is typically positioned in a respective semicircular region and may extend generally radially and perpendicularly inwardly from a distal peripheral linear edge of the top wall section.
This invention also features a floating marine dock or walkway that includes an elongate frame including a generally parallel pair of elongate frame elements for supporting a walking surface thereon. A plurality of suction float elements as previously specified, are secured to and depend from the respective frame components at longitudinally spaced apart locations thereof.
Other objects, features and advantages will occur from the following description of a preferred embodiment and the accompanying drawings, in which:

As further shown in
A representative suction float element 12 is depicted by itself in
Each suction float element 12 includes a typically buoyant exterior plastic shell 30 that may be composed of various types of marine grade material. Shell 30 includes a generally planar top wall section 32,
As shown in
As best shown in
The bottom of each float element 12 has a plurality of suction pockets 70 formed therein. Each pocket 70 includes a pair of elongate, generally parallel sides and a pair of rounded ends. In the version depicted herein, four suction pockets are formed in the bottom wall section of each shell 14. In particular, each pocket includes an opening or entrance formed in bottom wall section 50, and a cavity formed through and surrounded by a respective interior tube 71 (
The suction pockets 70 formed in the bottom wall section of each float element 12 provide both the float elements themselves and the overall dock 10 with greatly improved stability in the body of water W. This is represented in
It should be further understood that the dock elements may be arranged and oriented in various alternative ways to accommodate different lengths and widths of docks and walkways. In the version shown herein, the long (e.g., 4 foot) side of each float element) extends laterally beneath the elongate dock such that the connectors on the respective short sides of the float element are secured to respective longitudinal components of the dock frame. In other versions, where a narrower dock or walkway is involved, the float elements can be adjusted by reorienting them 90° so that the recesses and respective connectors formed along the longer (e.g., 4 foot) sides of the float element are used to secure the float element to the frame.
Typically, the float elements are spaced beneath the dock at predetermined intervals, which may be adjusted as required. It is unnecessary to form float elements continuously beneath the walkway. Interval arrangement makes the floating dock system much more efficient and cost effective. The float elements may be rearranged and reoriented as needed for particular floating dock and walkway applications.
Accordingly, the present invention relates to a floating marine dock structure and to suction float elements that are carried by framework of the floating dock in order to more stably and securely support the dock or walkway in a body of water. The suction float elements are particularly advantageous for use where the dock may be susceptible to instability and tipping due to rough seas and wave action, adverse weather conditions and application of an excessive or unbalanced load to the walkway.
While this detailed description has set forth particularly preferred embodiments of the apparatus of this invention, numerous modifications and variations of the structure of this invention, all within the scope of the invention, will readily occur to those skilled in the art. Accordingly, it is understood that this description is illustrative only of the principles of the invention and is not limitative thereof.
Although specific features of the invention are shown in some of the drawings and not others, this is for convenience only, as each feature may be combined with any and all of the other features in accordance with this invention.
