Description
- This application claims the benefit of United States Provisional Patent Application No. 61/872,201, filed Aug. 30, 2013.
- This invention relates generally to temporary liquid dams, dikes or barriers to retain or divert liquids on a surface, and more particularly to liquid dam assemblies of modular flexible components.
- It is often desirable to retain or divert liquid flows of relatively small depth, such as a few inches, with liquid dams that can be quickly and easily installed as needed, such as for example when pipes burst, liquid containers leak or spills occur, especially indoors. It is well known to provide modular liquid dams that can be assembled as needed, the dams comprising elongated members formed of a generally soft or tacky polymer material (e.g., polyurethane or polyvinylchloride) such that the bottom of the dam members provide sufficient contact with the substrate surface to prevent passage of the liquid under the dam. It is preferred that the dam comprise a number of portable segments or members assembled end-to-end, as the modular nature of the dam allows for formation of many different configurations as required. The members are abutted to form an elongated barrier, and the members may be provided with joining mechanisms. Examples of such devices are shown in U.S. Pat. No. 4,031,676, U.S. Pat. No. 5,236,281, U.S. Pat. No. 5,454,195, U.S. Pat. No. 6,022,172, U.S. Pat. No. 6,588,979, and U.S. Pat. No. 8,454,269.
- The efficacy of a modular liquid dam assembly depends significantly on the quality of the abutting connection between adjoining dam members. When the dam members comprise flat ends simply abutted together, it is often possible for liquid to pass between the dam members, especially since one dam member may shift relative to the other due to the force of the liquid or from outside influences. To address this various connection mechanisms have been developed. Some systems utilize mating members, such as a post member received within a socket member. Other systems utilize collars or other independent connectors that connect or encircle both adjoining ends. While such connection mechanisms may provide better security, they require extra time during assembly of the liquid dam, which may result in passage of liquid.
- It is an object of this invention to provide a modular liquid dam assembly that provides a more secure connection mechanism for adjacent dam members which allows the dam members to be quickly and easily joined.
- In general the invention is a modular liquid dam assembly comprising a plurality of individual elongated members or segments that can be quickly and easily assembled in an end-to-end relationship to form a temporary retainer or diverter of varying configurations and dimensions on a substrate surface to retain or direct liquid flow on the substrate surface. The members are of sufficient weight and have a base or bottom surface, preferably planar, of sufficient width to preclude passage of liquid beneath the member when placed onto the substrate. The members are composed of a soft, compressible, flexible, non-rigid polymeric elastomer material, such as e.g., polyurethane, polyethylene or polyvinylchloride, having a density, flexibility and conformation characteristics that allow the bottom surface to conform to some degree with imperfections in the substrate in order to provide a better seal.
- The adjacent dam members are provided with a magnetic connection mechanism or system comprising a magnet disposed within or exposed on the end of an adjacent dam member, the other adjacent dam member comprising a second magnet or a metal member disposed within or exposed on its end, such that when the two dam members are abutted, the magnetic connection maintains the dam members in abutting relationship. The ends of the dam members may be configured to include structural mating members providing a mechanical or frictional fit, such as a male/female combination of an extended post member received within a bore, to further enhance the connection in conjunction with the magnetic connection mechanism.
- Alternatively presented, the invention is a modular dam assembly comprising a plurality of dam members adapted to be assembled in end-to-end relation and a magnetic connection system adapted to temporarily connect adjacent said dam members; each of said dam members having ends adapted to abut with the ends of adjacent said dam members in a manner that precludes passage of liquid between said dam members; wherein each of said dam members comprises a first magnet disposed on or adjacent one said end and a second magnet or a metal member disposed on or adjacent the other said end; wherein the combination of said first magnet member of one said dam member with said second magnet or metal member of an adjacent other said dam member define said magnetic connection system. In addition, the an assembly wherein said first magnet and either said second magnet or said metal member are covered by a thin layer of polymer, and/or wherein said magnets further comprise anchoring members, and/or wherein said metal members further comprise anchoring members. The assembly may further comprise a structural connection system adapted to temporarily connect adjacent said dam members in a mechanical interlocking manner.
- Also presented is a method of assembling a modular dam assembly comprising the steps of providing a plurality of dam members; each of said dam members having ends adapted to abut with the ends of adjacent said dam members in a manner that precludes passage of liquid between said dam members; wherein each of said dam members comprises a first magnet disposed on or adjacent one said end and a second magnet or a metal member disposed on or adjacent the other said end; and wherein the combination of said first magnet member of one said dam member with said second magnet or metal member of an adjacent other said dam member connects said dam members; positioning two of said dam members in end-to-end abutting relation such that said first magnets of one said dam member magnetically connect with said second magnet or said metal member or an adjacent said dam member; and connecting additional dam members in like manner as required to complete said modular dam assembly. Additionally, wherein said step of providing a plurality of dam members comprises providing dam members comprising structural connection systems adapted to connect adjacent said dam members in mechanical interlocking manner; and wherein said step of positioning two of said dam members and said step of connecting additional dam members comprises interlocking adjacent said dam members.

FIG. 1 is a perspective view of one embodiment of the invention showing a pair of dam members prior to abutment. -
FIG. 2 is a partial longitudinal cross-sectional view of the dam members of the embodiment ofFIG. 1 . -
FIG. 3 is a partial longitudinal cross-sectional view of another embodiment showing a magnetic connection system comprising a magnet member and a metal member. -
FIG. 4 is a partial longitudinal cross-sectional view of another embodiment showing a magnetic connection system wherein the magnet members are disposed in the planar ends of the dam members and covered by a thin layer of polymer material. - The invention in various representative embodiments will now be described with reference to the drawings. In general the embodiments present a modular liquid dam, dike or barrier assembly comprising a plurality of individual elongated dam members or segments 11 having
ends 12 such that multiple dam members 11 can be assembled or abutted in an end-to-end relationship to form a temporary retainer or diverter to retain or direct liquid on a substrate surface. The configuration of theends 12 may be generally flat and perpendicular to the longitudinal axis as shownFIG. 3 , or they may be curved or angled in corresponding manner, or they may be formed with interlocking or interfitting three-dimensional mating structures or configurations, as shown for example inFIGS. 1 and 2 . - The dam members 11 are of sufficient weight and have a base or
bottom surface 13, preferably planar, of sufficient width to preclude passage of liquid beneath the dam member 11 when placed onto the substrate. The dam members 11 are composed of a non-rigid polymer material, such as e.g., polyurethane or polyvinylchloride, having a density and flexibility that allows thebottom surface 13 to conform to some degree with imperfections in the substrate in order to provide a better seal. The upper configuration of the dam member 11 may vary, and may for example be triangular (as shown), rectangular, curved, etc. in cross-section. Dam members possessing the characteristics described above are known in the industry. - The dam members 11 are provided with a magnetic connection system or assembly 21. The connection system 21 is a combination of members and may comprise a pair of
magnets 31, as shown inFIGS. 1 and 2 , or asingle magnet 31 in combination with ametal member 33, as shown inFIG. 3 . In a basic embodiment, each dam member 11 comprises first andsecond magnets 31 mounted one at eachend 12. Themagnets 31 are oriented such that opposite polarities are directed outwardly. Themagnets 31 may be embedded in thedam member end 12 such that the end of eachmagnet 31 is exposed, or themagnets 31 may be embedded a small distance inside thedam member end 12 such that a thin layer of polymer material covers eachmagnet 31 to protect themagnets 31, the layer being of insufficient thickness to interfere with the magnetic properties of themagnets 31. Preferably themagnets 31 are provided with anchoringmembers 32, which may comprise any physical construct that increases retention of themagnet 31 within the dam member 11. For example, theanchoring member 32 may comprise a shaft of increased diameter (as shown inFIGS. 1 and 2 ), a plate member (as shown inFIG. 4 ), a threaded rod (as shown inFIG. 3 ), radially extending legs, etc., embedded within the body of the dam member 11 to prevent removal of themagnet 31 from the dam member 11. - Alternatively, a
first magnet 31 may be utilized in one dam member 11 and ametal member 33 may be utilized in the adjacent dam member 11, themetal member 33 being composed of a material that is attracted by themagnet 31. As before, anchoringmembers 32 are preferably provided to better secure themagnets 31 andmetal members 32 within the dam members 11. - The magnetic connection mechanism 21 should be chosen such that the connection is suitably strong to resist separation from the forces expected to be encountered during normal use, but not so strong that separation of the dam members 11 is not readily accomplished when the dam assembly is to be disassembled. For example, a
magnet 31 with a diameter of approximately ¾ inches and pull strength of approximately 66 pounds has been shown to be suitable. - A structural connection or
mating system 24 having members capable of interfitting or interlocking may be provided such that in addition to the magnetic connection system 21 a mechanical or friction fit is achieved between adjoining dam members 11 when assembled. For example,structural connection system 24 may comprise a malepost member 22 received by a correspondingfemale socket member 23, as shown inFIGS. 1 and 2 . Themagnets 31 are then able to act in addition to the physical connection, onemagnet 31 being mounted in thepost member 22 and theother magnet 31 being mounted at the base of thesocket member 23, thus increasing the efficacy of the abutment. As before, asingle magnet 31 in combination with ametal member 33 may also be utilized. - In this manner a plurality of dam members 11 may be formed and stored until needed to retain or direct a liquid. When required, the dam members 11 are quickly assembled end-to-end to define the elongated liquid barrier. After the need for retention or diversion of the liquid has passed, the dam members 11 are quickly and easily disassembled.
- The embodiments discussed above and the figures are meant to be illustrative and not limiting. It is contemplated that equivalents and substitutions for elements set forth above may be obvious to those of skill in the art, and therefore the true scope and definition of the invention is to be as set forth in the following claims.
