A cover plate means extends from the drain pipe over to the wall for end support on an inner ledge means on the block wall, whereby a floor section can be laid over the cover plate and drain tile to blend into the remainder of the basement floor.

U.S. Pat. No. 4,757,651 titled Wall system, to Crites, teaches a wall system for use on a vertical wall, such as a basement wall, is disclosed. A drain conduit is positioned adjacent the wall footer and a collection member is mounted along the bottom of the wall. A plurality of connector conduits extend between the collection member and the drain conduit. In one embodiment a vertical support column is mounted adjacent the wall.

U.S. Pat. No. 4,869,032, titled Apparatus and method for waterproofing basements, to Geske, teaches a drainage control apparatus for basements having a poured concrete floor. The drainage system includes a plurality of drainage structures in an end-to-end abutting relationship. Each drainage structure has a vertical leg and a horizontal leg, with the vertical leg being positioned proximate to the vertical side wall of the basement and the horizontal leg resting upon the top of the foundation footing. The vertical leg includes a plurality of outwardly protruding embossments proximate the bottom end of the vertical leg. The vertical leg also includes an outwardly projecting, longitudinal spacer lip proximate the upper end of the vertical leg. Both the embossments and spacer lip touch the vertical basement side wall to maintain a gap between the vertical leg and the vertical side wall. The horizontal leg of the drainage structure includes a plurality of channels to direct water into a drain pipe.

U.S. Pat. No. 5,784,838, titled Drain for draining water from a basement floor, to Philips, teaches a basement wall drain unit that extends around the periphery of a basement next to the wall for draining away any potentially damaging moisture. The drain fits securely to a foundation wall before a concrete floor is poured in a basement. The drain further has a removable cap. The cap being removed after the concrete floor has been poured and hardened. The cap is for preventing wet concrete from filling the drain during installation of the basement floor or the like. Another feature of the invention is to provide a device and method that have spaced apart drainage holes in a channel for draining water from the basement area to a location under the basement floor.

U.S. Pat. No. 6,405,508, titled Method for repairing and draining leaking cracks in basement walls, to Janesky. teaches a method for repairing and concealing a crack in the interior surface of a basement wall, and for draining water admitted through the crack into a drain at the base of the wall. The method involves the steps of covering the crack, along the length thereof and down to the drain, with a thin, narrow strip of a water-absorbing, water-wicking fabric such as a layer of plastic foam or woven cotton. Thereafter, a thin barrier layer of an elastomeric caulk composition is spread thereover and beyond the edges thereof onto the surface of the basement wall to channel the flow of water from the wall crack, through the layer of wicking fabric, and down into the drain.

U.S. Pat. No. 6,672,016, titled Wall and sub-floor water drain barrier panel for basement water-control systems, to Janesky, titled a sub-floor, perimeter, L-shaped water drainage panel for new construction basements having walls and supporting footings for receiving and draining water running down the walls and/or water entering at the wall/footing interface. The plastic drainage panel is molded with a plurality of spaced frustroconical wells on vertical and horizontal sections thereof, to engage the wall and footing, and space the panels therefrom and to be filled with wet concrete composition, when the floor is poured, to support the wall and footing against the basement floor and prevent relative movement therebetween.

Each of the patents discussed above, are incorporated herein by reference for all purposes. Generally, most of these systems include a channel which receives water from the foundation walls and directs the water along its length and into a commercial pump to pass out of the basement. Variations and improvements have been introduced, such as having attachments means to more securely hold the system in place or having apertures to receive water at various lengths along the conduit rather than at a single location. All involve the same basic concept—a system with a way to direct water into the system, move it along its length and direct the water to a pump where it will be directed out of the basement.

As water seeps into the basement, it brings with it sediment and other particulates. Over time, these various particulates can build up within the channel and eventually impede the flow of water through the channel. Once blockage occurs, water may then seep into the basement.

SUMMARY OF THE INVENTION

The system of the present invention is designed to alleviate the problems associated with sediment/particulates clogging the flow of water through the conduit. The present drainage conduit has two channels rather than just one as found in existing systems. The present invention has a part of its design, a filtering material that serves to filter out sediments/particulates preventing any such sediments/particulates from entering the second flow channel. Additionally, the system utilizes apertures positioned along the length of the side wall of the first conduit to receive water at various locations. If blocking occurs at one area of the conduit preventing further inflow of water at that position, water can enter at any of the unclogged apertures.

This dual channel system provides a filtered second flow channel to receive water when the first flow channel is blocked at some points along its length. The system allows the water to rise into the second flow channel and bypass the blocked area and move back down into the first flow channel. By filtering the water, ensures that particulates are filtered from the water and thus do not prevent movement in the second flow channel.

In one aspect of the invention there is a basement drain comprising a frame and a filter element. The frame has a first flow channel, and a second flow channel. The first flow channel is positioned generally above the second flow channel. The first channel has an open end along its length. The frame is preferably formed from a flat sheet of flexible plastic. The frame, however, may be made of other useful materials, such as certain metals, such as aluminum. Based on the disclosure herein, the use of other materials would become readily apparent to one skilled in the art.

The filter element has a frame and a filter material disposed about said frame, the filter element disposed within the first channel. The filter element may have any size or shape such that it provides filter of sediments or other debris, thereby allowing the flow of water within the filter element. In a sense, the filter element provides a filter flow channel, or multiple flow channels depending on the construction of the filter element. The filter element is adapted to provide filtering into the first flow channel. It is contemplated that to increase the filter capacity, that a second filter element may be contained within the second flow channel.

In one embodiment, the frame is formed from six walls. A first flow channel is formed by the second wall connected to the third wall, and the sixth wall connected to the third wall. A second flow channel is formed by the third wall connected to the fourth wall, the fourth wall connected to the fifth wall, the fifth wall connected to the sixth wall, the sixth wall connected to the third wall. Preferably, the fifth wall has a plurality of openings to allow water to enter the second flow channel. The sixth wall forms a floor of the first channel and forms a ceiling of the second channel. The first wall has a free end along the length of the first wall. The first wall may have a plurality of wall spacers along its length to space the free end from the wall so that water dripping down the basement wall will be directed to one side of the first wall.

In one aspect of the invention, the first wall, third wall, and fifth wall are substantially perpendicular to the second wall, fourth wall, and sixth wall. Also, the second wall, fourth wall, and the sixth wall each have a substantially similar width.

In one aspect of the invention, the first wall is flexibly connected to said second wall. The second wall is flexibly connected to said third wall. The third wall is flexibly connected to the fourth wall. The fourth wall is flexibly connected to said fifth wall. The fifth wall is flexibly connected to sixth wall. In this particular embodiment of the invention, a single sheet of rigid flexible plastic, or other suitable material may be cut out from a roll of stock plastic, and then the particular walls created by forming longitudinal creases in the plastic.

In this embodiment, there would be a total of five longitudinal creases, one crease between each wall. Forming the basement drain this way allows, a low cost method of producing the frame of the water drainage device. After, the drain template is cut from the plastic, it can be easily stacked in a flat manner without taking up much space. When ready for installation, the frame can be folded into a proper configuration.

In one aspect of the invention, the sixth wall has a one or more connectors extending along a free end of the sixth wall. The connectors are adapted to connect to openings disposed about the third wall. Preferably, the connectors are tab-shaped. When folding the frame, the tabs are then inserted into the openings. Various shapes may be utilized to connect the sixth wall to the third wall.

A method according to the invention relates to the control and drainage of water which enters the walls and which must be drained away from the walls and out of the basement to the exterior. Typically, such a drainage method is accomplished by directing water through gaps between the floor and walls.

FIG. 1 depicts the water drainage device 10, wherein the water drainage device is installed in a subterranean room, such as a basement. FIGS. 2-6 depict in further detail the water drainage device.

Typically a subterranean room includes a foundation wall that is built on a footer and a floor that abuts the foundation wall. The wall illustrated is a block wall 26 but the system may be successfully implemented with other types of walls, such as, for example, concrete or limestone walls. Frequently, water builds up within the walls and can leak through the walls into the subterranean room. Building codes normally require that subterranean rooms be constructed to drain water from within a basement wall and redirect it out of the room. This may be achieved in a number of ways, including the use of drain and tile. The foundation wall may have a vapor barrier in the form of a membrane material or coating applied to further inhibit the flow of water into the basement and on to the basement floor 30.

A concrete block wall 26 is constructed with the use of concrete blocks which are hollow and are positioned vertically on top of each other aligning the hollow centers. As water enters into the concrete wall, the water flows through the hollow centers of the blocks and exits the wall from apertures 36 in blocks that are placed at intervals along the concrete wall. The water drainage device 10 is designed to receive this water, as more fully explained below, and direct the water along the device via water flow channels 19, 22 and toward a sump where the water is directed out of the basement.
