Tube for Preventing Water from Entering a Basin

The present application is a continuation of U.S. application Ser. No. 18/468,501, filed Sep. 15, 2023, which is a continuation of U.S. application Ser. No. 17/702,671 (now U.S. Pat. No. 11,828,080), which is a continuation of U.S. application Ser. No. 16/659,430 (now U.S. Pat. No. 11,313,141), filed Oct. 21, 2019, which are hereby incorporated by reference in their entirety.

Basins need a temporary means for protecting them while not in use. Basins include swimming pools, fracking pools, above-ground tanks, in-ground tanks, and other means for containing relatively large quantities of fluids. When empty, basins can be subjected to various forms of damage, such as damage from debris, rain damage, flooding damage, and other natural disaster damage. Additionally, it is desirable to prevent humans and animals from accidentally falling into the basin when not in use.

Conventional methods, such as covers and liners, have a number of drawbacks. For example, conventional covers are often not strong enough to support the weight of an animal, such as a deer, or a child, or are otherwise made out of strong material that is expensive. Additionally, covers and liners offer little protection from flood damage or other natural disasters. A superior and more cost-efficient means of protecting basins is necessary.

A containment tube designed to fit within the dimensions of the basin is filled with a filling fluid and sits within the otherwise empty basin. The containment tube is made of a flexible and water-tight material and has a valve for filling and a valve for draining. When not filled, the containment tube can be rolled up and stored conveniently. When filled with a filling fluid, such as water or air, the containment tube takes the shape of the basin and sits within the basin to prevent unwanted debris, animals, and other items or living beings from entering the basin or contaminating the containment fluid. The filled containment tube may also prevent damage to the basin. The filled containment tube fits snugly within the walls of the basin and re-distributes force evenly via hoop stress. In some embodiments, the containment tube has a zipper for ease of access to the interior of the tube for inspection or cleaning. Some embodiments include an exterior protective liner for protecting the containment tube from puncture.

The filled containment tube prevents objects from entering the basin. For example, the filled containment tube can support the weight of a small animal or child by re-distributing the weight throughout the tube, there preventing accidental injuries. Similarly, the containment tube protects the basin from damage by debris by inhibiting the debris from coming in contact with the basin, since the containment tube fills the interior of the basin. The containment tube also prevents unwanted fluid from filling and damaging the basin, such as flood damage or rain damage, because the unwanted fluid cannot enter water-tight containment tube nor can it seep through the contact between the water-tight containment tube and the walls of the basin. The containment tube can be manufactured to fit basins of different shapes and sizes in a relatively cost-effective manner. Additionally, the containment tube can be easily assembled and filled, and easily drained and put away for storage.

The Figures (FIG.) and the following description relate to preferred embodiments by way of illustration only. It should be noted that from the following discussion, alternative embodiments of the structures and methods disclosed herein will be readily recognized as viable alternatives that may be employed without departing from the principles of the embodiments.

Reference will now be made in detail to several embodiments, examples of which are illustrated in the accompanying figures. It is noted that wherever practicable, similar or like reference numbers may be used in the figures and may indicate similar or like functionality. The figures depict embodiments for purposes of illustration only.

A containment tube is water-tight and does not have any open sides. The containment tube is configured to receive a filling fluid, such as any liquid substance, such as water, wet concrete, other fluid, or even an expanding and hardening foam (such as polyurethane foam) or gas in certain configurations, which may be pumped into the tube. The containment tube is constructed from a waterproof and flexible material, such as vinyl-coated polyester, polyvisqueen or other material that prevents intrusion of fluid through its surface. In an embodiment, the polyvisqueen is between 5-15 millimeters in thickness. In some embodiments, the polyvisqueen is reinforced, for example, with an embedded webbing material such as nylon strands (e.g., string). The edges between pieces of water-tight material can be sealed together by at a seam using glue, pressing, wedge welding, or another sealing method.

A basin is a concave structure with an enclosed bottom and sides for holding a fluid and an open top, such as, swimming pools, fracking pools, above-ground tanks, in-ground tanks, and other means for containing relatively large quantities of fluids. The basin has a cross-sectional area and shape for both the bottom of the basin and the top opening of the basin. Some basins may have the same cross-sectional area and shape from the bottom to the top opening, whereas other basins may have different shape or size cross-section at one end. The basin also has a depth, which is the distance from the top opening of the basin to the bottom of the basin.

show a schematic of a process of manufacture of a top portion or a base portion of a containment tube. For simplicity, this section primarily refers to the portion as the top portion. The process of manufacture is used to construct the necessary base portion of the containment tube as well, as described in greater detail below.

shows a schematic of a sheetof flexible, waterproof material. The sheethas a length ofand a width of, which are greater than or equal to the dimensions of the cross-section of the top opening of the basin (or the cross-section of the bottom of the basin, if in relation to the base portion). The sheetmay be assembled piecewise to be the desired dimensions by sealing seamsfrom multiple pieces of flexible, waterproof material. Piecewise assembly of the sheetenables less material to be wasted, thereby keeping costs down, while maintaining the water-tight properties desired.

shows a schematic of a sheet ofoverlaid with an outline of a top portion. The size and shape of the top portionis determined based on the cross-sectional area of the top opening of the basin. The top portionis substantially the same as the cross-sectional area of the top opening of the basin. The top portionhas a size dimensions slightly less than the size dimensions of the cross-sectional area of the top opening of the basin, such that the top portion of the containment tube will fit within and span substantially all of the cross-sectional area of the top opening of the basin (seefor an example). For example, the schematic of the top portiondepicted inis circular in shape with a diameter, and thereby is for a basin that has a cross-sectional top opening that is also circular in shape and has a diameter slightly greater than the diameter. While the embodiment depicted inshow a circular top portion intended for a circular cross-sectional top opening, it should be noted that the top portion and corresponding cross-sectional top opening can be any shape, including but not limited to an oval, a triangle, a square, a rectangle, or a trapezoid.

shows a schematic of the top portion. The top portiondepicted inis the top portionofthat has been cut out from the sheet. The top portionhas the sealed seamsof the larger sheetand is waterproof and flexible even with the sealed seams.

Because the containment tube has both a top portion and a bottom portion, the above process of manufacture must either be performed to produce both portions. In some embodiments, the process of manufacture is repeated to produce a second portion. In one embodiment, the process of manufacture is repeated with different cross-sectional areas or shapes, if the basin requires such in order for the containment tube to fit snugly. For example, a basin may be a pool with sides that slope inwards towards the bottom of the pool. Accordingly, the top portion will be of a larger size than the base portion. In another embodiment, where the top portion and the base portion are the same shape and size, both portions can be manufactured simultaneously by layering two sheets of waterproof material for cutting.

In some embodiments, the top portion has a first valve for filling the containment tube

with a fluid. Similarly, in some embodiments, the top portion has a second valve for draining the fluid contained within the containment tube. Example fluid filling or draining apparatuses to attach to the valves may include a pump or hose or pipe, which may be supplied with fluid by a pump or gravity, and in the case of gas, a pressurized canister or compressor. In some embodiments, the top or bottom portion has a zipper for inspecting or cleaning the inside of the containment tube. These features can be added to the top and/or bottom portion after the stage of assembly shown in.

show a schematic of a process of manufacture of a side portionof the containment tube.shows a schematic of a two-dimensional view of a sheetto be constructed into the side portion. The sheetis a made of a waterproof, flexible material, such as those previously discussed in the overview section and in relation to. The sheethas a heightand a width. The heightand widthof the sheetare determined dependent upon the dimensions of the basin. The heightis determined to be slightly less than or equal to the depth of the basin, such that when assembled, the containment tube fits within the basin. The lengthis described in relation to.

shows a schematic of a three-dimensional construction of the sheetinto the side portion. To form the side portion, the sheetis positioned such that the height-wise edges are overlapped and sealed. Thereby, the lengthof the sheetmust be long enough that the sheetcan create the sealand fit substantially within the basin while making contact with the walls of the basin. In practice, the lengthof the sheetmay be equal to or slightly longer than the perimeter (or largest perimeter) of the basin, depending on the width of the overlap formed for the seal. Alternately, the lengthcan be described as that, when sealed, the perimeter of the side portionis the same as the perimeter of the top portion and the bottom portion (or the greater of the two if the top portion and bottom portion have different perimeters). For example, as shown in, the side portion has the same diameteras the top portionof.

In some embodiments, side portionmay be assembled piecewise. That is, multiple pieces of flexible, waterproof material may be assembled piecewise with waterproof seams to achieve the desired heightand widthof the sheet. In some embodiments, the piecewise assembly of the sheetis similar to that of the sheetof. Additionally, after the side portionis assembled from the sheet, the height of the side portioncan be increased by stacking a second assembled side portionon top and attaching with a waterproof seam around the circumference of the two side portions.

shows an alignmentof the top portionthe base portionand the side portion. The top portionis aligned above one opening of the side portionand the bottom portionis aligned below another opening of the side portion, opposite the top portion

shows the containment tubeconstructed when the top portionand the bottom portionhave been attached to the side portion. The top portionand the bottom portionare attached to the edges of the side portionby the sealsin accordance with the alignmentshown in. The sealsare water-tight. In some embodiments, the sealsare air-tight. The sealsmay be formed by the methods as described in the overview.

In one embodiment, after assembly of the containment tube, the containment tubemay be put through various tests prior to use in the basin. For example, the containment tubemay be filled with a filling fluid to check that the sealsare strong and not leaking. To test for water-tightness of the seals, the containment tubeis filled with water or another liquid. To test for air-tightness of the seals, the containment tube is filled with air or another gas.

shows an example of a filled containment tubesitting within a basin. The containment tubemay be the same or similar to the containment tube. As depicted in, the basinis an above-ground swimming pool with a circular cross-section top opening and bottom. The containment tubehas a circular top portion that fits within and spans substantially all of a cross-sectional top opening of the basin. That is, the containment tubesits within the basinsuch that the side-portions of the containment tubeare in contact with the side walls of the basin, and the top and bottom portions of the containment tubeare sealed to the side portion and may or may not be in direct contact with the walls of the basin. Thereby, the seals between the side portion and the top portion enable the containment tubeto span the entirety of the opening of the basinand prohibit any objects from entering the basin. Hence, while the top portion itself may or may not span the entirety of the cross-sectional top opening of the basin, the top portion spans substantially all of the top opening to enable sealing with the side portion and enable containment tubeto prohibit entrance of objects into the basin. While the basinand the containment tubeare both circular in cross-sectional shape in the embodiment shown in, the basinand the containment tubecan take on other cross-sectional shapes, including but not limited to oval, triangular, square, rectangular, or trapezoidal.

The top portion of the containment tubehas a first valveand a second valve. The first valveis configured for receiving a filling fluid. The second valveis configured for draining the filling fluid. In some embodiments, the containment tubemay have only one valve which is configured to both receive and drain a filling fluid. In other embodiments the first valveor the second valvemay be located elsewhere on the containment tube such as the side portion or the bottom portion.

In some embodiments there is a protective sleeve between the containment tubeand the basin. The protective sleeve is a flexible material, such as nylon. The protective sleeve protects the containment tubefrom puncture, wear, or other damage that may be caused by the interior of the basin. The damage could be cause by sharp edges or imperfections in the walls or bottom of the basin, or be debris that had fallen into the basinprior to the insertion of the containment tube. In one embodiment, the protective sleeve covers the side portion of the containment tube. In another embodiment, the protective sleeve covers the bottom portion of the containment tube. In another embodiment, the protective sleeve covers both the side portion and the bottom portion of the containment tube.

is a flowchart of a processfor creating a containment tube. A top portion is createdfrom a flexible and waterproof material, the top potion fits within a top opening of a basin. A bottom portion is createdfrom a flexible and waterproof material, the bottom potion fits within a bottom of the basin. A side portion is createdfrom a flexible and waterproof material. The top portion is sealedto a first side of the side portion. The bottom portion is sealedto a second side of the side portion, wherein the second side of the side portion is substantially opposite the first side of the side portion. Substantially opposite refers to the top portion and the bottom portion being opposite one another, though not necessarily parallel, and separated by the side portion.
