ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention:
This invention relates to pump stand inserts for sump pump containers or sump liners which are sub-floor reservoirs for the reception of ground water which seeps into basements or other subterranean rooms. Generally the water is channeled to the sump reservoir and then pumped therefrom by a sump pump via a discharge conduit to an exterior location.
2. Description of the State of the Art:
Sump pump containers or sump liners are designed for use in water control systems of the types disclosed in my prior U.S. Pat. No. 5,314,313, 5,501,044, and 5,927,955 for example.
In such systems, the sump pump container is a reservoir for the reception of the water seepage which is channeled thereto, and the conventional sump pump contained therewithin includes a water-level actuated lever arm switch which energizes the pump to discharge the water from the container whenever the water level reaches a predetermined height, as sensed by a float attached to the lever arm.
The size of the sump pumps incorporated within the sump liner container will vary depending upon the requirements of different installations and/or whether a battery-operated secondary pump is included to assure evacuation in the event of a power failure. If the sump pumps are too close to each other on the inner floor of the container their lever arms and floats can engage each other, the other pump, or the wall of the container and become inoperative. In such cases the container fills and overflows into the basement before the occupant becomes aware that a problem exists, unless the system is provided with a water level-sensing alarm as disclosed in my U.S. Pat. No. 5,314,313.
In the case of conventional sump containers for holding two sump pumps, generally an AC-powered pump and a battery-operated pump, the diameter of the floor of the container may be too small to receive two pumps, side-by-side, without interference with each other and/or with the wall of the container.
It is known to incorporate a sump pump stand in a sump basket to elevate the pump above the floor of the basket to prevent mud and debris from entering the pump, and reference is made to U.S. Pat. No. 5,249,930 for its disclosure of such a pump stand. The pump stand of the reference is integral, has a sloped platform provided with circumferential openings, a central opening, supports for supporting the sump pump on the sloped platform, and legs for supporting the stand on the floor of the container basket.
SUMMARY OF THE INVENTION
The present invention relates to a novel pump stand for a sump pump container for overcoming or avoiding the aforementioned problems, and for adapting the sump container to receive and support two or more sump pumps at different elevations or at the same elevation above the floor of the container where the diameter of the frustoconical container is sufficiently greater than the diameter of the floor of the container to accommodate the two pumps, side-by-side, sufficiently-spaced from each other and from the wall of the container to prevent interference.
The present pump stand is an integral unit comprising a level, somewhat-circular platform having at least four spaced peripheral legs and at least two closely-spaced central legs, and a partition line on the platform for bisecting the pump stand into two similar half-stands, each having at least two peripheral legs and at least one central leg, which half-stands are stackable upon one another to support a sump pump at a greater elevation within a sump container, if desired.
