## Background
BACKGROUND
An age old flood control tool is the sandbag. Sandbags are typically stacked in layers to divert water to an area where the water will not cause property damage. Even though the bag is porous, the sand filler is dense enough to prevent water flow through the bag. The sand also adds weight so that floodwater will not normally move the sandbag.
One problem with using sandbags is that the bags must be filled, carried and stacked. The sandbags are heavy. Preparing a sandbag dike is labor intensive and possibly backbreaking work. In cases where manpower is limited and flash floods are possible, there may not be enough time to fill, move and stack sandbags to prevent property damage. A portable dike is desired which can be rapidly constructed and positioned with minimum manpower.
U.S. Pat. No. 4,921,373 to Coffey discloses a fluid-filled dike having a frame with a plurality of legs. Fluid, such as water, is often readily available at a flood site. Using the water to fill a container eliminates the need for sand. One drawback, however, of the Coffey invention is that the dike is difficult to assemble. The legs must be assembled, adjusted and affixed to the ground.
U.S. Pat. No. 5,040,919 to Hendrix discloses a water-filled dike partition. The partition has a triangular cross-section. The partition walls include triangular gussets, which are rigid enough to maintain the triangular cross-section. Legs are not needed. A gusseted dike partition, however, may be undesirably bulky to hand carry. Accordingly, possible drawbacks of the Hendrix invention are excessive weight and lack of portability.
U.S. Pat. No. 4,981,392 to Taylor discloses a multi-partition water-filled dike. The partitions are cylindrical shaped and interconnected along a horizontal mid-plane by a sheet of high-strength material. Water fills the cylindrical partitions to maintain the cylindrical partition shape. The partitions are stacked to form a dike. One benefit of the Taylor invention is that the partitions are relatively easy to individually fill. One drawback is that for each partition length, at least two partitions must be filled with water. This takes twice the effort as filling a single partition.
Water and sand take time to fill dike partitions and sandbags, respectively. Accordingly, in U.S. Pat. No. 6,164,870 to Baruh, which is incorporated herein in its entirety, a dike was disclosed which was a quick and more efficient way of providing a portable dike, which is also is lightweight. It would be desirable for the portable dike not only to serve as a portable dike, however, it extreme cases, it would be desirable for the portable dike to be converted into a floatation device.
SUMMARY
The dike of the present invention includes interconnected inflatable portable dike and floatation devices. Each portable dike and floatation device includes an upper and lower partition. Each partition includes an inlet for inflating the partition. The lower partition is water fillable and normally holds water to weight the portable dike and floatation device. The upper partition is air fillable and normally holds air to shape and support the lower partition. In addition, each of the portable dike and floatation devices include at least one support member, which is dimensioned to be received within the portable dike and floatation device to provide added shape not only when the device is acting as a water diversion device but also as a floatation device.
The portable dike and floatation device is portable and compresses and folds for easy transport. To set up the portable dike and floatation device, each section pre-inflates. Handles are provided on each section and attach to the upper partition. Lifting the handles lifts the upper partition and pre-inflates both the upper partition and the lower partition with air. Pre-inflation pre-shapes the partitions.
Water fills at least a portion of the lower partition. It can be appreciated that filling the lower partition with water increases the air pressure within the lower partition. This increased air pressure helps to shape the lower partition.
The lower partition has vents in fluid communication with the upper partition. The vents release excess pressure from the lower partition. The vents also guide air from the lower partition into the upper partition as water fills the pre-shaped lower partition. This increases the air pressure in the upper partition and enables the upper partition to become rigid to shape and support the lower partition. Air pressure also shapes the upper partition to inhibit water from splashing over the dike.
According to one aspect of the invention, the vents include pressure relief valves to regulate pressure within the lower partition. Accordingly, a desired pressure may be maintained in the lower partition to optimize partition shape. According to another aspect of the invention, the upper partition inlet includes a pressure relief valve for regulating pressure within the upper partition. Should the upper partition exceed a pre-determined pressure, the relief valve would release air to prevent the upper partition from exploding, or leaking due to over-pressurization. The lower partition forms a triangular prism having a floor and two sides. The upper partition surrounds the two sides. Preferably, the upper partition includes at least two lobes designed to cause the lower partition to maintain the prism shape. The lobes cover each side of the lower partition according to one embodiment of the present invention. Other configurations, however, may be used. The lobes are both triangular prism shaped, and inverted with respect to the lower partition. Accordingly, inflation of each partition forms the portable dike and floatation device section into a square prism shape.
In accordance with one embodiment, a portable dike and floatation device having a lower partition; an upper partition attached to the lower partition; the lower partition forms a triangular prism having a floor and two sides; the upper partition has two lobes, the lobes cover the two sides, the lobes have a triangular prism shape, and wherein the inner and upper partition forms a square prism shape when the lower partition and the upper partition inflate; and at least one support member within the portable dike and floatation device.

DETAILED DESCRIPTION
FIG. 1 shows a house 2, surface water 4, and an inflatable dike 6. The dike 6 is comprised of a plurality of interconnected portable dike and floatation devices 10. As shown in FIG. 1, in use the individual dike portable dike and floatation devices 10 can be aligned in an end-to-end formation forming a barrier or wall to protect homes and other structures. The dike 6 preferably surrounds much of the house 2 and blocks the surface water 4. In addition, each of the dike portable dike and floatation devices 10 is preferably flexible to accommodate ground irregularities such as the rocks 8.
FIG. 2 shows a roadway 3 and the surface water 4 adjacent the roadway 3. The dike 6 stands between the surface water 4 and the roadway 3 and blocks the surface water 4 from flowing onto the roadway 3. As shown in FIG. 2, the dike 6 flexes and conforms to the roadway curvature.
FIG. 3 shows an inflatable portable dike and floatation device 10. As shown in FIG. 1, the portable dike and floatation device 10 has a base or lower surface 12, a pair of sides 14, a top or upper surface 16 and a pair of ends 18. As shown in FIG. 3, the portable dike and floatation device 10 has a generally rectangular cross section. However, it can be appreciated that the cross sectional configuration of the portable dike and floatation device 10 can be triangular or any other suitable configuration.
As shown in FIG. 3, the portable dike and floatation 10 from end to end 18 has an overall length 13 of preferably 2.0 to 10.0 feet, and more preferably 4.0 to 8.0 in length. The sides 14 from the base 12 to the upper surface or top 16 of the portable dike and floatation device 10 has a height 15 of preferably 0.5 to 2.0 feet and more preferably about 1.0 feet in height 15. The top surface 16 from edge 21 to edge 21 has a width 17 of preferably 0.5 to 2.0 feet and more preferably about 1.0 feet in width 17. The height 15 and the width 17 of the portable dike and floatation device 10 are preferably equal; however, it can be appreciated that the ratio of the height 15 to the width 17 can vary from 0.5 to 2.0.
Within the floatation device 10, as shown in FIG. 3, the portable dike and floatation device 10 has a lower partition 22 and an upper partition 24. The lower partition 22 and the upper partition 24 inflate. The lower partition 22 typically inflates with water to weight the portable dike and floatation device 10. Meanwhile, the upper partition 24 typically inflates with air to shape and support the portable dike and floatation device 10. Accordingly, the lower partition 22 typically weighs more than the upper partition 24.
It can be appreciated that using fluids including air and water to fill each portable dike and floatation device 10 not only shapes each portable dike and floatation device 10 to a desired degree, but also allows the portable dike and floatation device 10 to flex around curved roads and various non-uniform ground surfaces. While the lower partition 22 inflates with water, it may also be partially, or fully, inflated with another fluid such as air. Additionally, the lower partition 22 pre-inflates with air to ease interconnection between adjoining sections. While the upper partition 24 typically inflates with air, a combination of water and air may inflate the upper partition 24 to further weight the portable dike and floatation device 10.
The lower partition 22 has a nominally triangular cross-section and forms a right triangular prism having a floor 26 and a pair of sides 28. The lower partition 22 includes a water inlet 60 and a water outlet 62 each mounted on one side 14 of the portable dike and floatation device 10 and adjacent the floor 26. The water inlet 60 allows entry of water and air into the lower partition 22. Meanwhile, the water outlet 62 provides a drain for the removal or exiting of water from the lower partition 22.
The lower partition 22 includes a reinforced top edge 30 dividing the sides 28. The reinforced top edge 30 cooperates with the upper partition 24 to shape and reinforce the lower partition 22. According to one aspect of the invention, the reinforced top edge 30 is fabricated from steel cable.
The sides 28 can include optional air vents 32. The air vents 32 are defined adjacent the top edge 30. The upper partition 24 surrounds at least part of the lower partition 22 to shape and support the portable dike and floatation device 10 when the upper partition 24 inflates. The upper partition 24 has discrete lobes 36, 38 covering each side 28 of the lower partition 22. Each of the lobes 36, 36 has a triangular cross-section and forms a pair of right triangular prisms. The pair of triangular prisms of each lobe 36, 38 are formed from the upper surface or top 16 and a side 14 of the portable dike and floatation device 10, and a side 28 from the lower partition 22. The lobes 36, 38 maintain fluid communication with each other and with the lower partition 22 via the vents 32. The upper partition 24 includes an air inlet 70 for inflation of the upper partition 24 with air.
According to one aspect of the invention, the vents 32 include a pressure relief valves 34 to regulate lower partition 22 pressure. When the pressure within the lower partition 22 exceeds a desired level, air is released through the pressure relief valves 34 into the upper partition 24 to inflate the upper partition 24.
In use, the lower partition 22 fully inflates to a desired pressure prior to full inflation of the upper partition 24. Full inflation of the upper partition 24 occurs when the air pressure in the upper partition 24 meets a desired level, exceeding ambient air pressure. According to one aspect of the invention, the upper partition 24 has two lobes, 36, and 38, which are in fluid communication with each other. Each lobe 36, 38 fully covers one side 28 of the lower partition 22. It can be appreciated that while the lobes 36, 38 fully covering the sides 28 of the triangular prism shaped lower partition 22 are disclosed, the lobes 36, 38 may be of any shape suitable for shaping and supporting the lower partition 22. Numerous lobes may be used to cover portions of the sides, or may be internally mounted within the water-fillable lower partition 22.
The upper partitions 14 can also includes a pressure relief valve 34 to bleed air out of the upper partition 24 at a desired pressure and thereby regulate pressure within the upper partition 24. Air is released so that the dike will not burst, or leak, from over-pressurization. The pressure relief valve 34 also assures that water flow into the dike will not be inhibited by over-pressurization. The pressure relief valve 34 is removable to enable air to fill each of the partitions 22, 24, when the handles 90 lift as shown in FIGS. 7 and 8.
It can be appreciated that the vents 32 can be constructed without the pressure relief valve 34. In this embodiment, the vents 32 are optional overflow passages. In use, when the lower partition 22 is filled, i.e. the water level reaches the vents 80, water spills through the vents into the upper partition 24. Water partially fills the upper partition 24 to add weight to the portable dike and floatation device 10. Weighting the upper partition 24 is desirable when the dike is used to stop flowing water, or water over a foot deep. Otherwise, it is normally most desirable to full the upper partition 24 only with air. It can be appreciated that air pressure within the portable dike and floatation device 10 increases continually as water is added.
In addition, as shown in FIG. 3, the portable dike and floatation device 10 can also include at least one support member 50, which is dimensioned to be received within the portable dike and floatation device 10. The support member 50 provides the portable dike and floatation device 10 with additional rigidity. In addition, the support member 50 provides addition rigidity and stability to upper surface 16 of the portable dike and floatation device 10 during use as a floatation device. Specifically, the support member 50 provides rigidity and additional support to the portable dike and floatation devices 10 on an outer edge 19 where the sides 14 intersect with the upper or top surface 16.
As shown in FIG. 3, the support member 50 is preferably positioned within the portable dike and floatation device 10 and is parallel to each end 18. However, it can be appreciated that the support member 50 can also extend from one end 18 to the other end 18 of the portable dike and floatation device 10. The support member 50 preferably extends from the floor 26 of the lower partition 22 to the upper surface or top 16 of the portable dike and floatation device 10. The support members 50 are preferably positioned near each end 18 of the portable dike and floatation device 10. The support member 50 provides the portable dike and floatation device with added support not only in use as a water diversion device but also as a floatation device or raft 100 (FIG. 9).
Each of the support members 50 are preferably positioned inward of the ends 18 of the portable dike and floatation device 10. The support member 50 is preferably spaced 19 at least two (2) to twelve (12) inches from each end 18 of the portable dike and floatation device 10 for a device having an overall length 13 of 4 to 6 feet. The space 19 between the end 18 of the portable dike and floatation device 10 and the support member 50 is preferably flexible or semi-flexible and can assist with forming a water tight seal when the portable dike and floatation devices 10 are connected in an end 18 to end 18 configuration or arrangement as shown in FIGS. 1 and 2.
Each portable dike and floatation device 10 has at least one support member 50 and more preferably at least two support members 50. It can be appreciated that the portable dike and floatation device 10 can have a plurality of support members 50, wherein the support members 50 are positioned equal distance from one another within each device 10 and having a spacing 19 from end 18 to support member 50, and support member 50 to support member 50 of at least 6 to 12 inches.
The support member 50 is preferably constructed of a semi-rigid material, or reinforced material such as nylon, pliable vinyl or other suitable material, which can provide the added rigidity and support to the portable dike and floatation device 10. It can be appreciated that the support member 50 can be constructed of any pliable material, wherein the material is pliable but provides added support and rigidity to the support member 50 during use as a water diversion device and as a floatation device or raft 100.
As shown in FIG. 3, on the top or upper surface 16 of the portable dike and floatation device 10, each of the lobes 36, 38 of the upper partition 24 includes an air inlet 70 for inflating the upper partitions 24 with air, and a pressure relief valve 72. The air inlets 70 are preferably configured to allow ambient air to fill the upper partitions 24 during set up of the portable dike and floatation device 10 and are able to accept a manual pump or gas cylinder (FIG. 11) for inflation as a floatation device. Overall, the air inlets 70 provide a means for inflating the portable dike and floatation device 10, while the pressure relief valves 72 regulate the air pressure within the lobes 36, 38 of each of the upper partition 24. In use, if the air pressure within either of the lobes 36, 38 of the upper partition 24 exceeds a desired air level, air is released through the pressure relief valves 72. The air inlets 70 are preferably equipped with a threaded connector or quick connect topping valve. However, it can be appreciated that any suitable connector can be used for the air inlet 70.
The top or upper surface 16 of the portable dike and floatation device 10 can also include at least one pressure relief valve 74, which is in communication with the lower partition 22 of the portable dike and floatation device 10. The at least one pressure relief valve 74 is optional and can be implemented instead of the vent 32 and pressure relief valve 34 or as an additional pressure regulator within the lower partition. As shown in FIG. 3, the pressure relief valve 74 regulates the air and/or water pressure within the lower partition. Accordingly, if the air pressure within the lower partition 22 exceeds a desired air or water pressure, air can be released from the lower partition 22 via the pressure relief valve 74.
Each of the air inlets 70, and pressure relief valves 72, 74 are preferably recessed and/or have a means to be recessed when not in use. The recessing of the air inlet 70, and pressure relief valves 72, 74, provides the portable dike and floatation device 10 with a smooth or planar surface for use as a floatation device. In addition, each of the air inlets 70 and pressure relief valves 72, 74 can be optionally fitted with a screw cap (not shown) which fits on top of the air inlet 70 and pressure relief valves 72, 74 and provides a smooth upper surface or top surface 16 of the portable dike and floatation device 10 during use as a raft or floatation device 100.
The portable dike and floatation device 10 also includes a plurality of handle 90, which are configured to assist with the handling and positioning of the portable dike and floatation device 10 both as a device to redirect water and as a floatation device. As shown in FIG. 3, each of the handles 90 is preferably secured or attached to the upper surface 16 of the portable dike and floatation device 10. The handles 90 are preferably made of a lightweight material such as a plastic. However, the handles 90 can be constructed of any suitable lightweight material.
It can be appreciated that the portable dike and floatation devices 10 can be attached to one another in an end-to-end 18 relationship to form a portable dike 6 by any suitable method. For example, the portable dike and floatation devices 10 can be cabled together with short cables, Velcro® straps and buckles or other suitable method. The ends 18 of the portable dike and floatation devices 10 are preferably connected in an end-to-end 18 relationship in a watertight manner so that the portable dike and floatation devices 10 can divert water as necessary.
The portable dike and flotation device 10 can be constructed from a variety of different materials. For example, the device 10 may be made from a water permeable material, such as a mesh or similar material, or a water impermeable material such as nylon, a pliable watertight fabric or heavy-duty vinyl can be used for the portable dike and floatation device 10.
FIG. 4 shows a portable dike and floatation device 10 in accordance with another embodiment. As shown in FIG. 4, the portable dike and floatation device 10 has a lower partition 22 and an upper partition 24. The lower partition 22 typically inflates with water to weight the portable dike and floatation device 10. Meanwhile, the upper partition 24 typically inflates with air to shape and support the portable dike and floatation device 10. Accordingly, the lower partition 22 typically weighs more than the upper partition 24.
It can be appreciated that using fluids including air and water to fill each portable dike and floatation device 10 not only shapes each portable dike and floatation device 10 to a desired degree, but also allows the portable dike and floatation device 10 to flex around curved roads and various non-uniform ground surfaces. While the lower partition 22 inflates with water, it may also be partially, or fully, inflated with another fluid such as air. Additionally, the lower partition 22 pre-inflates with air to ease interconnection between adjoining sections. While the upper partition 24 typically inflates with air, a combination of water and air may inflate the upper partition 24 to further weight the portable dike and floatation device 10.
The lower partition 22 has a nominally triangular cross-section and forms a right triangular prism having a floor 26 and a pair of sides 28. The lower partition 22 includes a water inlet 60 and a water outlet 62 each mounted on one side 14 of the portable dike and floatation device 10 and adjacent the floor 26. The water inlet 60 allows entry of water and air into the lower partition 22. Meanwhile, the water outlet 62 provides a drain for the removal or exiting of water from the lower partition 22. As shown in FIG. 4, the floor 26 of the lower partition 22 can included a plurality of floor openings or holes 57 to allow water to fill the lower partition 22. The openings or holes 57 within the floor 26 of the lower partition 22 are preferably equally spaced from end 18 to end 18 of the portable dike and floatation device 10. As shown in FIG. 4, the portable dike and floatation device 10 preferably has at least two (2) rows of three (3) openings 57 along the floor 26 of the lower partition 22. It can be appreciated that the openings 57 within the floor 26 of the lower partition 22 can be located or positioned anywhere on the floor 26 including between the support member 50 and the nearest end 18.
The lower partition 22 can also include a reinforced top edge 30, which divides the sides 28. The reinforced top edge 30 cooperates with the upper partition 24 to shape and reinforce the lower partition 22. According to one aspect of the invention, the reinforced top edge 30 is fabricated from steel cable. The sides 28 include air vents 32. The air vents 32 are defined adjacent the top edge 30. The upper partition 24 surrounds at least part of the lower partition 22 to shape and support the portable dike and floatation device 10 when the upper partition 24 inflates. The upper partition 24 has discrete lobes 36, 38 covering each side 28 of the lower partition 22. The lobes 36, 38 maintain fluid communication with each other and with the lower partition 22 via the vents 32. The upper partition 24 includes an air inlet 70 for inflation the upper partition 24 with air.
According to one aspect of the invention, the vents 32 include pressure relief valves 34 to regulate lower partition 22 pressure. When the pressure within the lower partition 22 exceeds a desired level, air is released through the pressure relief valves 34 into the upper partition 24 to inflate the upper partition 24. Accordingly, the lower partition 22 fully inflates to a desired pressure prior to full inflation of the upper partition 24. Full inflation of the upper partition 24 occurs when the air pressure in the upper partition 24 meets a desired level, exceeding ambient air pressure.
The upper partitions 14 can also includes a pressure relief valve 34 to bleed air out of the upper partition 24 at a desired pressure and thereby regulate pressure within the upper partition 24. Air is released so that the dike will not burst, or leak, from over-pressurization. The pressure relief valve 34 also assures that water flow into the dike will not be inhibited by over-pressurization.
In addition, as shown in FIG. 4, the portable dike and floatation device 10 can also include at least one support member 50, wherein a first support member 50 is positioned on the end 18 of the portable dike and floatation device 10 and a second support member 50 is positioned near the ends 18 of the portable dike and floatation device 10.
