METHOD AND APPARATUS FOR PREVENTING BASEMENT DRAIN OVERFLOW

Abstract

An inflatable system is described herein, including a body, a top, a bottom, an interior cavity, and a fluid inlet. In one aspect of the present teaching, the top and the bottom are on opposite sides of the body, approximately parallel to one another. The stem opening is located on the top of the body, wherein the stem opening allows the entry of fluid into the interior cavity of the body. The inflatable system is made of a material which allows for stretching when the inflatable system is inflated.

IV. DETAILED DESCRIPTION

[0019] With reference now to FIGS. 1-3, the presenting teaching includes an inflatable system 10 having a body 18, a top 12, a bottom 14, an interior cavity 16, and a fluid inlet 20. In one aspect of the present teaching, the top 12 and the bottom 14 are on opposite sides of the body 18, approximately parallel to one another. The fluid inlet 20 is located on the top 12 of the body 18, wherein the fluid inlet 20 allows the entry of fluid into the interior cavity 16 of the body 18. The inflatable system 10 is made of a material which allows for stretching when the inflatable system 10 is inflated.

[0020] With reference now to FIGS. 1-3, the inflatable system 10 is in the sewer 22, such that a portion of the top 12 of the body 18 remains above a floor 24. In one aspect of the present teaching, when using an approximately five inch diameter sewer 22, the body 18 has an uninflated length of approximately fourteen inches long and an uninflated width of about four inches, the stem opening can be about five inches long, and the top 12 of the body 18 can stick out above the floor 24 by about two inches. A perimeter can be drawn on the basement floor around the inflatable system 10 and the sewer 22, so that people can be made aware of the inflatable system 10. This can be a dotted line two inches outside the perimeter of the sewer 22, and the line can be different colors in order to be more visible.

[0021] With continuing reference to FIGS. 1-3, in one aspect of the present teachings, a pump 26 is attached to the fluid inlet 20 in order to fill the interior cavity 16 with air. Upon receiving the air, the body 18 increases in size to create a substantially water tight seal with the sewer 22. In one aspect of the present teachings, the inflated body 18 has an inflated length of about 16.5 inches and an inflated width of five inches, so that an inflated top portion 28 extends approximately four inches above the floor 24. Once the body 18 is inflated such that a substantially watertight seal is created with the sewer 22, the pump 26 can be disconnected from the fluid inlet 20. It is to be understood that any type of pump for inserting fluid into the body 18 can be used, as long as chosen using sound engineering judgment. It is also to be understood that any type of fluid inlet 20 for allowing the fluid to enter the body 18 can be used, as long as chosen using sound engineering judgment. It is further to be understood that the dimensions of the inflatable system 10 are not critical, as long as the inflatable system 10 creates the substantially watertight seal.

[0022] With continuing reference to FIGS. 1-3, in one aspect of the present teachings, once the need for the inflatable system 10 to no longer create a watertight seal with the sewer 22, the inflatable system 10 can be deflated back down to its original size.

[0023] With reference to FIGS. 1-4B, in one aspect of the present teachings, the system 10 can be installed on a toilet 30. The system 10 could be inserted either in the outlet 32 at the base of the toilet 30, or a second outlet 34 underneath the toilet 30. FIG. 4A shows the system 10 inflated in a pipe 36 of the toilet. FIG. 4B is an exploded cutaway view showing the system 10 inflated in the pipe 36. A fluid inlet 20′ in FIG. 4B can be a device that allows for the physical pumping of the body 18, but in one aspect of the present teaching can also be a remotely controlled fluid inlet 20′, such that the body 18 can be inflated and deflated remotely, since access to the system could be difficult. It is also to be understand that any of the aspects of the present teachings can be controlled remotely, not matter where located.
