Description

BACKGROUND OF THE INVENTION

The invention is directed to a large capacity transportable berm for use in emergency, temporary or military situations, which is adaptable for use on substantially all-terrain.

Numerous situations arise where transportable berms, containments or flexible bladders are both useful and necessary. A primary use of these is with military operations where fluid, whether it be drinking water, waste water or contaminating materials such as petroleum and other similar products which need to be contained for storage or later proper disposal. Disaster areas also require the use of containments for the temporary storage of the above referred to fluids. Finally, in areas of extremely fast growth, there sometimes is a need for a temporary containment.

The instant invention has for a primary object a transportable containment capable of retaining large volumes of fluid for later distribution or disposal.

Another object of the invention is a transportable berm which can be easily and quickly assembled or disassembled.

Another object of the invention is a transportable berm capable of retaining large volumes of fluid over an extended period of time.

Another object of the invention is a large capacity berm which is capable of being easily disassembled and folded or arranged in small units for storage and transport.

SUMMARY OF THE INVENTION

The invention is directed to a transportable all-terrain berm for collecting fluid. The berm is comprised of flexible impervious sheeting material configured to form a floor, which may be supported in a generally horizontal position, and opposed side and end wall sections which are connected along first edges with the floor and together along opposed ends. Retaining members are arranged to extend from second edges of the side and end wall sections at selected spaced positions. Also, support members are arranged to extend from the second side edges of the side and end wall sections at locations between the retaining members.

A plurality of braces, preferably A-frames, are positioned about the flooring. Each brace or A-frame comprises first and second legs pivotally engaged at their upper ends. A spacer member is provided for selectively positioning and maintaining the lower ends of the first and second legs in spaced positions. A hook member is located on an outer surface of one of the first and second legs adjacent the upper end.

With the braces arranged about the floor in vertical positions, the retaining members are engaged with the hook members to maintain at least spaced sections of the side and end wall sections in a generally vertical position against a leg of the brace member forming a containment area for the described berm.

The retaining members comprise loops formed of straps which are affixed with the side sections adjacent the side edges spaced from the floor. The loops engage over the upper ends of said brace members and with the hook members.

The support members comprise straps affixed adjacent the second side adjacent of the side and end members which are formed into loops, which are arranged between adjacent of the support members. Alternatively, the support members may comprise flexible sheeting extending from the second edge of the end and side members which are formed into an extended loop which extends between the retaining members.

A stabilizer, generally comprising a rod having down-turned ends, is engaged with upper ends of the braces interconnecting adjacent ones. The support members are engaged over the stabilizers.

The A-frames may be spaced at generally between 4 and 6 foot intervals, depending upon the weight of the product, along said side and end wall sections, and at about 2 foot intervals from the corners of the flooring.

The berm is a collapsible berm capable of being folded for storage and transport. The berm is also capable of being assembled to form a containment area for storing fluid. The containment area, which is formed of flexible impervious sheeting, includes a generally flat floor area surrounded by opposed generally vertical side and end wall members. A plurality of braces are arranged in vertical positions about the flooring in position to engage with the end and side wall members. There are retaining members and support members which are engaged with and extend outwardly of and about the end and side wall members.

Stabilizer members, which engage with and extend between adjacent of the braces, are adapted to engage with the support members to assist in maintaining the side and end wall members in generally vertical positions.

The braces are preferably formed of U-shaped metal beams pivotally joined adjacent one end. Side sections of the metal beams overlap and form the pivot with an enclosed open end. The opening is designed to receive the down-turned ends of the stabilizer members.

DESCRIPTION OF A PREFERRED EMBODIMENT

Referring now in more detail to the drawings, the invention will now be described in more detail.

Turning now to FIG. 1, a primary version of the all-terrain berm or ATB transportable containment berm of the invention is shown at 10. Berm 10 is formed of flexible impervious sheet material, usually a fabric coated with synthetic material. The berm comprises a containment area A which includes a floor 12, see FIG. 5, opposed end wall section 14 and opposed side wall sections 16, each engaged along their inner edge with an edge of flooring 12 and along opposed edges with each other forming containment area A. Retaining members 20 are secured adjacent outer edges 18 of side and end wall sections 14 and 16 in substantially equally spaced positions. Between retaining members 20 and along edges 18 there are provided support members 22, 23.

Both retaining members 20 and support members 22 may comprise straps secured adjacent their opposed ends with end and side wall sections 14 and 16 forming loops which extend beyond edges 18. The straps are generally woven and are of a heavier material than the flexible sheet material. Alternatively, the support members may comprise an extension of the flexible sheet material extending between adjacent retaining members 20 and formed into a loop as shown at 23. See FIGS. 4a and 4b.

The flexible sheeting material may comprise a fabric, woven, knitted or a non-woven which is coated with a synthetic material. The coating material must be resistant to degrading when contacted with petrochemicals or other contaminants which are desired to be retained. Polyurethane is generally a suitable coating. The flexible sheeting must be of sufficient strength to resist tearing under the pressure created by the contained fluid. The flexible sheeting must also resist undue wear due to the berm being set up and taken down repeatedly. Suitable fabrics are manufactured by several known manufacturers, two of which are the Seaman Corporation of Wooster, Ohio, and Cooley, Inc. of Pawtucket, R.I.

A plurality of braces 24 are provided to retain side and end wall sections 14, 16 in generally vertical positions. Each brace 24 preferably comprises an A-frame comprised of a pair of U-shaped metal beams 26 joined adjacent upper ends with a pin 28 forming a pivotal connection. Adjacent the lower ends of beams 26 there is provided a spacer 30 which, when engaged with spaced beams 26, maintains them in fixed position.

Beams 26, as shown in FIGS. 3a and 3b, include spaced and parallel side edges 32 through which bores pass to receive pins 28 and 29 which secure the A-frame in position. Pin 29 may be used to also secure spacers 30 in positions parallel with beam 26 when the brace is in its collapsed position for storage or transport.

Adjacent lower end of beam 26 an additional bore 34 is provided to receive an anchor which acts to secure brace 24 in fixed position with the ground or its supporting surface. The anchor may comprise a peg or screw pin passed through bore 34 and into the ground or support surface. Alternatively the anchor may comprise a cord or chain secured at one end with beam 26 and at its other end with peg or screw 35, which is then embedded in the ground as shown in FIG. 1.

Adjacent the upper end of brace 24 is provided a hook 27 or other suitable retaining member. Also, adjacent the same upper end, overlapping parallel sides 32 of beams 26 form an enclosed opening 36.

Rods having down-turned opposed ends form stabilizers 38. Each stabilizer is preferably formed to be between 4 and 6 feet in length with the down-turned end being between 4 and 6 inches in length. The stabilizers, which are located at the corners of the containment, may be slightly shorter than the stabilizers extending along the end and side wall sections, i.e. about 3.5 feet depending on the placement of the braces 24.

The corner sections are slightly rounded and are shown in FIGS. 2a, 2b and 5. Each corner is formed by folding excess of the flexible sheet material, to overlap and then heat sealed along lines 40 as shown in FIG. 2b. A support member 22 may be attached along this section to retain the corner in the vertical position as shown.

Additionally, secondary bracing in the form of two straps 64, attached at each corner, may be necessary when large volumes of fluid are contained. These straps are connected over the upper pivoted end of braces 24 which are adjacent the corners. The straps are drawn downwardly and away from containment 16, where they are secured with the ground or support surface by spikes 66.

It is noted that the corner forming arrangement of the flexible sheet material forms no part of the instant invention and any known corner forming arrangement is acceptable.

Turning now to FIGS. 1 and 5, a top view of the general arrangement of the berm of the invention is shown. Braces 24 are arranged in equally spaced positions, i.e. between about 4 to 6 feet apart, along both the side and end walls 14, 16. Braces 24 are positioned 2 feet from each corner section. Stabilizers 38 are engaged in openings 36 adjacent the top of the braces. Flexible sheeting with dimensions of about 24′×32′ is positioned within the arranged braces 24 with side and end walls 14, 16 in engagement with inner legs 26 of braces 24. Retaining members 20 are secured over the upper ends of the braces and in engagement with hook 27. Also, support members 22 or 23 are engaged over stabilizers 38. The retaining members and support members act to hold the end and side wall sections in a generally vertical position and in engagement with the inner leg of brace members 24. Stabilizers 38 further act to maintain the braces in vertical positions. Straps 64 secure with braces 24 adjacent each corner section to provide additional support for these areas.

In the described condition, the berm is arranged to receive fluid for storage. The berm also may act to retain fluid which is to be removed at desired times and in desired amounts.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
