FIG. 1 illustrates afloor drain 100 in accordance with one or more embodiments of the present invention, positioned relative to abasement floor 200,foundation wall 210 and afooting 220. Thefloor drain 100 is installed generally flush with thebasement floor 200. While thefloor drain 100 is exemplarily positioned proximate to thefoundation wall 210, it should be noted that thefloor drain 100 may be positioned elsewhere, such as towards the middle of thebasement floor 200. As illustrated, thefloor drain 100 may be installed as part of a basement waterproofing system. For example, thefloor drain 100 may be fluidly connected to abasement sump 240 via aconduit 230 to facilitate extraction of collected water. In one embodiment, theconduit 230 may be implemented using a conduit as described in copending U.S. patent application Ser. No. 11/471,867 to Andras which is hereby incorporated herein by reference in its entirety. Likewise, thesump 240 may be implemented in accordance with copending U.S. patent application Ser. No. 11/529,060 to Andras which is also hereby incorporated herein by reference in its entirety. - According to one or more embodiments, the
floor drain 100 may include anupper chamber 110 and alower chamber 120, as illustrated inFIG. 2 . Theupper chamber 110 is generally open to the interior of the basement, and may be constructed and arranged to collect water from the surface of the surrounding basement floor. Thefloor drain 100 may include adrain cover 130, as detailed inFIG. 2A , having a plurality ofapertures 135 through which water may enter theupper chamber 110. Theapertures 135 may be of any size, shape and orientation, but should generally be designed and positioned to both promote water entry and prevent clogging. In at least one embodiment, thedrain cover 130 may be detachable, such as with a snap-off technique, to allow access to the interior of thefloor drain 100 for cleaning and/or maintenance. Thelower chamber 120 may be fluidly connected to theupper chamber 110. In some embodiments, thelower chamber 120 may be generally smaller than theupper chamber 110 in dimension. - According to one or more embodiments, the
floor drain 100 may include a valve to regulate flow of water from theupper chamber 110 to thelower chamber 120. Various types of valves commonly known to those skilled in the art may be implemented. In some embodiments, the valve may be a one-way valve, such as a spring loaded ball valve. In other embodiments, the valve may include a single movable component. For example, in at least one embodiment, the valve may comprise acantilever 140, as illustrated inFIG. 3 , to regulate flow of water from theupper chamber 110 to thelower chamber 120. - The
cantilever 140 may generally include aweighted portion 142 and aregulator 145. In some embodiments, thecantilever 140 may be configured to rotate about a pivot point. Theweighted portion 142 may balance theregulator 145 in a resting position such that theregulator 145 blocks fluid passage from theupper chamber 110 to thelower chamber 120. Water collected in theupper chamber 110 may exert a force on theregulator 145 to overcome the balance of thecantilever 140. Thus, theregulator 145 may be moved away from its resting position, allowing fluid passage from theupper chamber 110 to thelower chamber 120. In some embodiments, the weight of about one to two teaspoons of water in theupper chamber 110 may be sufficient to open thecantilever 140. When theupper chamber 110 no longer contains a volume of water sufficient to disrupt the balance of thecantilever 140, theweighted portion 142 will restore the balance and theregulator 145 will return to its resting position to block fluid flow. Depending on the rate of water collection in theupper chamber 110, thecantilever 140 may be opened periodically or continuously. Theregulator 145 may contain alip 148 to direct water towards thelower chamber 120. - According to one or more embodiments, the
floor drain 100 may also include a separator in abase 115 of theupper chamber 110, constructed and arranged to minimize clogging of the valve. For example, the separator may include a screen, filter or grate. In at least one embodiment, the separator may comprise abasket 150 in abase 115 of theupper chamber 110, as illustrated inFIG. 4 and detailed inFIG. 5 . Thebasket 150 may extend into thelower chamber 120, and may generally be constructed and arranged to minimize and/or prevent clogging of the valve. For example, thebasket 150 may be aligned with the valve to capture dirt and debris as water passes from theupper chamber 110 to the valve. In some embodiments, thebase 115 may slope towards thebasket 150 to promote drainage of water from theupper chamber 110 through thebasket 150. Thebasket 150 may be removable for cleaning or maintenance. Thebasket 150 may contain alid 155 having a plurality of apertures, such as a mesh or screen. The apertures should generally be designed and positioned to both promote passage of water and block debris. Thelid 155 may be removable to allow access to the interior of thebasket 150, such as for cleaning. - In some embodiments, an
outlet 158 of thebasket 150 may cooperate with the valve to regulate flow of water from theupper chamber 110 to thelower chamber 120. For example, in embodiments where the valve comprises acantilever 140, thecantilever 140 may function in mechanical cooperation with theoutlet 158. In the resting position for thecantilever 140, as illustrated inFIG. 6 , theregulator 145 may block theoutlet 158, preventing fluid flow. A force exerted by collected water in theupper chamber 110 may disrupt the balance of thecantilever 140. Theregulator 145 may be moved away from theoutlet 158 to an open position, as illustrated inFIG. 6A , allowing fluid flow to thelower chamber 120. Theweighted portion 142 may eventually restore the balance of thecantilever 140, returning theregulator 145 to its closed resting position against theoutlet 158. Beneficially, if thecantilever 140 was to become damaged for some reason, it would fall into thelower chamber 120 leaving theoutlet 158 open so as to prevent basement flooding. - In at least one embodiment, the valve, such as the
cantilever 140, may be integrated into the structure of thebasket 150. For example, as illustrated inFIG. 6 , thecantilever 140 may be connected to thebasket 150. A hinge or othermechanical attachment 159 may join thecantilever 140 to thebasket 150 and may serve as a pivot point for thecantilever 140. Beneficially, the valve may be accessed by simply removing thebasket 150 from thefloor drain 100. - As discussed above, the
floor drain 100 may be installed as part of a basement waterproofing system. Anoutlet 125 in the lower chamber 120 (FIG. 1 ) may be fluidly connected to a basement sump via a sub-floor drainage conduit. In operation, water collected in theupper chamber 110 may flow to thelower chamber 120 and may then be conveyed to the basement sump via the sub-floor drainage conduit for extraction from the basement structure. - In at least one embodiment, the
lower chamber 120 may be generally air resistant to promote the establishment of a closed basement waterproofing system. Without wishing to be bound by any particular theory, a closed system may serve to eliminate any airflow path between sub-floor and above-floor levels. Such a closed system may aid in containing radon gas and bacteria at the sub-floor level. Additionally, the closed system may promote energy conservation, such as by alleviating the need to dehumidify the basement environment. The nature of the valve regulating flow between theupper chamber 110 and thelower chamber 120 may influence the extent to which thelower chamber 120 is air resistant. For example, in some embodiments thelower chamber 120 may be about 99% air resistant. In embodiments wherein the valve comprises acantilever 140, the closed resting position of theregulator 145, as well as theupper chamber 110 water level in the open position, may serve to maintain air-resistance in thelower chamber 120. The air resistantlower chamber 120 may be connected to other components of a closed basement waterproofing system, as discussed above, including a drainage conduit and sump. - In some embodiments, the disclosed
floor drain 100 may be a modular assembly, multiple components of which may be interchangeably and detachably coupled together for customized installation. Afloor drain element 160, as illustrated inFIG. 7 , may have anupper chamber 110 constructed and arranged to collect water, and have an air resistantlower chamber 120 in fluid communication with theupper chamber 110. Thefloor drain element 160 may, for example, be about one foot in length. A valve may be included in thefloor drain element 160 to regulate flow of water from theupper chamber 110 to thelower chamber 120. Abasket 150 may also be included in thefloor drain element 160 to protect the valve from clogging. In some embodiments, thefloor drain element 160 may be coupled to one or more upperchamber extender elements 170, as illustrated inFIG. 8 , to increase an effective length of the upper chamber so as to create an extended upper chamber. The upperchamber extender elements 170 may be provided in various lengths for design flexibility. For example, and without limiting the scope of the present disclosure, a first upperchamber extender element 170 may be about one foot in length, and a second upperchamber extender element 170 may be about six inches in length. The upperchamber extender element 170 may alternatively be substantially identical to thefloor drain element 160 ofFIG. 7 , including an air resistant lower chamber. - Structural design features of components of the
modular floor drain 100, such as those defining a mating system, may be used to assemble the components. In some embodiments, an assembly system involving male and female mating sections or connectors may facilitate assembly of the floor drain without requiring an adhesive or mechanical attachment. For example, an end of afloor drain element 160 may include agroove 200 configured to removably receive atongue 210 in an end of an upperchamber extender element 170. Depending on the nature of the mating features, a force may be applied to ensure connection between the detachable floor drain segments. - Any combination of floor drain components may be coupled to assemble a floor drain with a desired length and/or functionality. For example, a one foot
floor drain element 160 may be coupled between two one foot upperchamber extender elements 170 to create a three foot assembled floor drain. In some embodiments, additional six inch upperchamber extender elements 170 may be applied to each end as illustrated inFIG. 9 to create a four foot assembled floor drain. In other embodiments where it may be desirable to include a second air resistant lower chamber, an additionalfloor drain element 160 may be coupled into the floor drain design. Upper chamber end caps 180, as detailed inFIG. 10 , may be applied to enclose distal ends 185 of an assembledfloor drain 100. Asingle drain cover 130 may be of a sufficient length to accommodate an assembled floor drain or, alternatively, multiple drain covers 130 may be applied in series. - A floor drain kit may be provided for assembly of a drain in accordance with one or more embodiments of the present invention. For example, the floor drain kit may include a floor drain element having an upper chamber constructed and arranged to collect water, and having an air resistant lower chamber in fluid communication with the upper chamber. The kit may further include a valve, such as a cantilever, for regulating flow of water from the upper chamber to the air resistant lower chamber. The kit may also include at least one upper chamber extender element. The upper chamber extender elements may be of a variety of lengths to enable customized installation. Some upper chamber extender elements may serve solely to extend the upper chamber. Other upper chamber extender elements may be substantially identical to the first floor drain element, including an air resistant lower chamber. The kit may include one or more end caps for enclosing distal ends of the upper chamber of an assembled floor drain. A basket configured to be removably received in a base of the upper chamber as discussed above may be included. A removable drain cover defining a plurality of apertures may also be provided in the kit.
- Existing basement waterproofing systems may be retrofitted in accordance with one or more embodiments of the present invention. For example, a preexisting basement floor drain may be replaced with a floor drain constructed and arranged substantially as described herein. Fluid connections may be made between the new floor drain and other components of a preexisting basement waterproofing system. Additional components, for example a drainage conduit or basement sump, may also be replaced or installed as part of a retrofit application.
- In some embodiments, an antimicrobial agent, commonly known to those skilled in the art, may be incorporated into the floor drain material prior to molding or extraction in order to impart antimicrobial properties to the resulting drain. For example, the antimicrobial compound may be added in an amount of about three to five percent by weight. Without wishing to be bound to any particular theory, a basement floor drain having an antimicrobial active surface may be effective in preventing the development of a harmful biofilm thereon.
- Other embodiments of the basement floor drain of the present invention, and methods for its installation and use, are envisioned beyond those exemplarily described herein.
- As used herein, the term “plurality” refers to two or more items or components. The terms “comprising,” “including,” “carrying,” “having,” “containing,” and “involving,” whether in the written description or the claims and the like, are open-ended terms, i.e., to mean “including but not limited to.” Thus, the use of such terms is meant to encompass the items listed thereafter, and equivalents thereof, as well as additional items. Only the transitional phrases “consisting of” and “consisting essentially of,” are closed or semi-closed transitional phrases, respectively, with respect to the claims.
