Abstract
An expandable-volume liner is usable with a collapsible liquid holding tank frame consisting of top and bottom rails spaced apart by vertical struts. The expandable-volume liner has pliant impervious side walls, a pliant impervious floor panel and at least one pliant impervious collapsible bag extending outwardly from the liner. Each bag is optionally extendable between its respective surrounding top and bottom rails and adjacent struts to conform the tank to the differing footprints presented by various sites and the volume of liquid necessary to accomplish the task at hand. The liners are especially suited to firefighting applications and can be used in conjunction with existing frames built for non-expandable volume liners.
Description
- This application claims priority to U.S. Provisional Application No. 62/113,202 which was filed Feb. 6, 2015.
- This invention relates generally to collapsible portable tanks for storing liquids and more particularly concerns the pliant, impermeable liners used with such tanks.
- Portable tanks for storing liquids typically consist of a frame of rigid top and bottom rails spaced by rigid vertical struts. The corners of the tank and the midpoints of two opposite top and bottom rails are hinged. The opposed hinged rails can be V-folded toward the center of the tank until the other rails come together in parallel. My earlier U.S. Pat. No. 8,746,478 describes one type of collapsible tank frame in detail, noting that such tanks are usually about 30″ high, from 6′ to 18′ on each side and capable of holding from 500 to 5,000 gallons of water.
- Whatever the size of the tank and the nature of the collapsible hardware, the frame generally unfolds into a predetermined and invariable square or rectangular footprint. More recently, frames have been designed with multiple hinges in opposite side rails allowing the same frame to be unfolded into one of two such footprints.
- The tanks are often necessary in firefighting scenarios in which water is not readily accessible at the site. In practice, the folded tank is stored on, and transported by, a fire truck dispatched to the site of the fire. On site, the tank frame is unloaded, unfolded and filled with water carried by a tanker truck to the site. The tanker truck may be the transporting fire truck. As the water is being exhausted from the tank by the firefighters, the tanker truck travels to and from a water supply station to refill the tank.
- Folded tanks are usually stored on the rack of a transporting fire truck and, in common practice, only one tank is stored on the truck. The possibility of storing multiple tanks on the same truck is an expensive, space eating and deployment-time increasing luxury rarely used in firefighting applications. But the tank to be used in a given application must take into account the demands of the fire and the distance from the deployed tank to a remote water supply for refilling the tank. So two competing criteria, volume and footprint, have a major impact on the decision as to the size of the tank to be stored on the transporting truck. On one hand, in order to accommodate a wider range of possible storage capacity requirements, a larger tank is preferred. On the other hand, because of unique site features, such as irregular terrain or immovable obstacles, the largest site footprint available may be quite restricted. Therefore, in order to accommodate a wider range of footprint alternatives, a smaller tank is preferred.
- It is, therefore, an object of the invention to provide a liquid storing collapsible portable tank having a footprint changeable to comply with a footprint presented by the site at which the tank will be used. And it is a further object of this invention to provide a liquid storing collapsible portable tank of expandable maximum volume.
- In accordance with the invention, a liner is provided for a collapsible, portable, liquid holding tank frame having top and bottom rails spaced apart by vertical struts. The liner has pliant impervious side walls and a pliant impervious floor panel. At least one opening through the pliant impervious side walls is sized to be surrounded by the top and bottom rails and two adjacent struts of the frame. At least one pliant impervious collapsible bag, one for each opening, has a mouth welded to its corresponding opening. Each bag is extendable from its mouth between its respective surrounding top and bottom rails and adjacent struts and outwardly from the side walls to its closed end. Each mouth has at least one strap connectable at one of its ends to the top or bottom rail and at its other end to the bottom or top rail, respectively. Each strap extends between its corresponding adjacent struts so that its corresponding bag, when folded from its closed end to its mouth into a stored condition, can be secured in the stored condition by its at least one strap.
- Other objects and advantages of the invention will become apparent upon reading the following detailed description and upon reference to the drawings in which:
-
FIG. 1 is a top perspective view of a preferred embodiment of an empty liner mounted on a collapsible liquid holding tank with three of four expandable bags extended from the liner; -
FIG. 2 is a side perspective view of the empty expandable liner ofFIG. 1 mounted on the collapsible liquid holding tank with the three of four expandable bags extended from the liner; -
FIGS. 3A and 3B are a side elevation view of the empty expandable liner ofFIG. 1 mounted on the collapsible liquid holding tank with the three of four expandable bags extended from the liner; -

FIG. 6 is a side perspective view of the expandable liner ofFIG. 1 mounted on the collapsible liquid holding tank with the liner and the three extended expandable bags filled with liquid. - While the invention will be described in connection with a preferred embodiment thereof, it will be understood that it is not intended to limit the invention to that embodiment or to the details of the construction or arrangement of parts illustrated in the accompanying drawings.
- Looking at
FIGS. 1-4 , a collapsible, portable, liquid-holding tank frame 10 is seen in an empty condition. Theframe 10 shown has top andbottom rails vertical struts 15 and hinged at the four corners and midpoints of two opposite sides of theframe 10. Theframe 10 supports aliner 20 formed by pliant,impervious side walls 21 and a pliant,impervious floor panel 23. As shown, the upper edges of thesidewalls 21 are fitted withgrommets 25 and are secured by lacing 27 to thetop rails 11. - At least one opening, and as shown four
openings 29, are provided through theliner side walls 21. Eachopening 29 is surrounded by two proximaladjacent struts 15 of theframe 10 and the portions of the top andbottom rails frame 10 lying between its two proximaladjacent struts 15. As shown, each of the four top andbottom rails tank frame 10 are spaced by sixstruts 15, so eachside wall 21 appears in five side wall segments. However, any number ofstruts 15 at any desired spacing could be used. - For the tank shown, at least one of the segments is adapted to provide a
drain passage 17 for evacuation of liquid from theliner 20 after use. Thus, theliner 20 shown has nineteen wall segments, five in each of threeside walls 21 and four in theother side wall 21, through whichopenings 29 could be provided. However, in the illustrated application, only four of the segments haveopenings 29. As best seen inFIG. 5A , when theliner 20 is filled with liquid, thedrain passage 17 will have been folded over thetop rail 11 and secured to the inside face of itsside wall 21. - Returning to
FIGS. 1-4 , at least one pliant, impervious,collapsible bag 30 is provided, one for each opening 29 through theside walls 21. Themouth 31 of eachbag 30 is welded or otherwise sealed along its perimeter to the perimeter of itscorresponding opening 29 through theside walls 21. As shown, eachbag 30 can be independently and optionally extended from itsmouth 31 outwardly from its respectiveliner side wall 21. - Continuing to look at
FIGS. 1-4 , for storage, eachbag 30 can be, and one of thebags 30 has been, folded from its closedend 33 to itsmouth 31. The foldedbag 30 may then be secured in the folded condition against the tank side wall bystraps 35 or other types of fasteners. At least one and, as shown two,straps 35 can be used between the correspondingadjacent struts 15 of theirrespective bags 30. As best seen inFIG. 1 , the lower end of eachstrap 35 is connectable to thebottom rail 13 or to thetank liner 20 proximate thebottom rail 13, as shown by wrapping the lower end of thestrap 35 around thelower rail 13 and fastening it to itself with hook-and-loop fasteners 37. Thestrap 35 is then extendable upwardly across the foldedbag 30 and overtop rail 11 and connectable at its upper end to the inside of thetank wall 21 between the correspondingadjacent struts 15, perhaps by snaps, buckles or, as shown, mating segments of hook-and-loop material 39. Thestraps 35 may be narrow, as shown, or wide enough to extend fully across theirrespective bags 30 in the stored condition. The four segments having openings are preferably, and as shown, in hingedmid-point walls 21 of the tank so that, when the tank is collapsed, the foldedbags 30 are interior to thecollapsed liner 20. - Returning to
FIGS. 1-4 , in deploying a tank on a site, thetank frame 10 is oriented on the site in a manner which will permit theliner floor panel 23 and anybags 30 intended to be extended from the tank to lie within the site footprint. Theframe 10 andliner 20 are unfolded and secured in their orthogonal use configuration. Thestraps 35 or other mechanisms used to secure thebags 30 in the stored condition are then disconnected and thebags 30 extended outwardly from the tank between their respectivevertical struts 15. Any number ofbags 30 suited to the site footprint and needed for increased tank volume can be extended. For the embodiment as shown, the tank includes and extends fourbags 30. - Turning now to
FIGS. 5 and 6 , the deployed tank has been filled with liquid which, for many applications and particularly for firefighting applications, will be water W. Theliner 20 and theextended bags 30 will be simultaneously filled with water W as the liquid level rises in the tank. Thus, thecollapsible bags 30 increase the storage capacity of the tank while simultaneously allowing theliner 20 to fit within the standard frame dimensions for the desired size of tank. For example, by extending one 500gallon bag 30 from an otherwise 2,000gallon liner 20 associated with a 2,000gallon frame 10, a tank capacity of 2,500 gallons of water W is possible using the 2,000gallon frame 10. The extension of twobags 30 would afford a tank capacity of 3,000 gallons of water W using thesame frame 10. - Looking at
FIG. 4 , grips 19 are shown fixed to thefloor panel 23 of theliner 20 for use in manipulating theliner 20 to aid in discharging the liquid from theliner 20 and/or to collapse the tank after use. Similarly, one ormore grips 19 may also be fixed to thecollapsible bags 30 to aid in discharging liquid from theextended bags 30 and/or to fold theextended bags 30 after use. - The increase in storage capacity without any corresponding increase in frame size minimizes the costs and the deployment time, and simplifies the transportation and storage, of the tank. Furthermore, a
collapsible bag liner 20 can be deployed in an existing standard-liner frame, thereby increasing storage capacity while totally eliminating the cost of acquiring a new frame. And, by selection ofappropriate bags 30 for extension, the footprint of the expanded volume tank can be tailored to suit the footprint presented by the site. - Thus, it is apparent that there has been provided, in accordance with the invention, an expandable-volume liner for a collapsible liquid holding tank has been provided that fully satisfies the objects, aims and advantages set forth above. While the invention has been described in conjunction with a specific embodiment thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art and in light of the foregoing description. Accordingly, it is intended to embrace all such alternatives, modifications and variations as fall within the spirit of the appended claims.
