Definitions

  • the present invention generally concerns the design and operation of containment devices for hazardous materials. More specifically, the present invention is directed toward a portable rapidly deploying containment device for recovery and containment of hazardous materials.
  • Description of the Prior Art Recovery and containment of hazardous substances is a continuing problem for industries that encounter spills, leaks, or other contaminated waste in their normal course of business. Indeed, the potential for a liquid chemical leak or spill exists wherever chemicals are used. Any industry handling potentially harmful material is subject to legal, economic and other consequences resulting from delayed, inadequate, or otherwise improper containment of hazardous chemical spills. In the shipping industry alone, millions of dollars are spent rectifying situations involving hazardous chemical spills. For example, the trucking industry is continually faced with spills of fuel or other potentially hazardous chemicals.
  • the invention comprises a portable rapidly deploying hazardous material containment device which may be easily adapted to receive and contain a hazardous material.
  • the containment device includes a framework structure that is movable between an erect open prism configuration and a collapsed compact configuration. In the prism configuration, the containment device includes a base and four side walls. The hazardous material is received and contained by a canopy disposed within the side walls of the device.
  • the framework of the containment device comprises rods, where each rod is pivotally joined to another rod by a scissors-type connection intermediate the ends of the rod; and hubs, where each hub receives an end portion of at least two rods along a separate axis of the hub, such that the rods are pivotally joined to the hubs and each rod pivots in relation to the hub along a single axis of rotation.
  • the rods rotate about this single axis of revolution from the collapsed configuration, where the rods are substantially parallel to one another, to the open erect configuration.

  • a portable rapidly deploying hazardous material containment device capable of receiving and containing a hazardous material.
  • the containment device includes a frame that is movable between an erect open configuration and a collapsed compact configuration. In the erect configuration, the containment device includes a base and four side walls, with a canopy disposed within the walls.
  • the containment device comprises rods, where each rod is pivotally joined to another rod by a scissors- type connection intermediate the ends of the rod; and hubs, where each hub receives an end portion of at least two rods along a separate axis of the hub, whereby the rods are pivotally joined to the hubs and each rod pivots in relation to the hub along a single axis of rotation.
  • This configuration allows the rods to rotate about the single axis of rotation from the collapsed configuration, where the rods are substantially parallel to one another, to the erect open configuration.
  • a fastening mechanism may be affixed between opposing hubs of the erect unit.
  • a stop mechanism may be affixed between opposing hubs of the erect unit.
  • the containment device of the present invention is a complete integrated, modular structure, which is rugged, compact, and flexible in design.
  • the containment device includes a frame that is designed for rapid setup as well as rapid breakdown.
  • the device includes an exterior canopy that is preferably preattached to the articulate frame which expands to a vertical prism shape when erected.
  • the containment device is self-supporting, which eliminates the need for supplementary erection devices, such as push poles and supplementary support devices, such as center poles.
  • the self-supporting nature of the containment device is derived from its articulate frame.
  • the articulate frame consists of a plurality of rods or struts interconnected to hubs by pivotal joints.
  • Each hub which may interconnect with as many as four rods, includes an attachment mechanism which enables the exterior canopy to attach to a hub, depending upon whether the hub is located on the upper or lower portions of the articulate frame. Examples of such attachment mechanisms include clips, buttons, snaps, hook and loop fasteners, and adhesives.
  • the structure of the containment device of the present invention is arranged such that the plurality of rods and hubs form a lattice framework.
  • this lattice framework forms a rectangular prism in which the canopy rests to form the basic receptacle for the containment device.
  • the rods lay parallel to one another with groups of hubs disposed on both ends of the rods.
  • the unique design of the frame of the containment device of the present invention allows the device to rapidly deploy from the closed compact configuration 10, depicted in Fig. 1, to the open erect prism shaped configuration 12, depicted in Fig. 2.
  • the containment device In the closed configuration, the containment device easily compacts in size, because of the unique relationship between hubs 12, 18 and rods 16.
  • the containment device when deploying the containment device from the collapsed to expanded configuration, it opens similar to an accordian, where the user need only lower hubs 12 positioned at the upper portion of the framework downward toward the lower portion of the framework.
  • This unique configuration further provides the containment device, while in its expanded configuration, with enhanced rigidity through post-tensioning of hubs 12, 18 and rods 16.
  • the containment device provides the shipping industry with a unit that may be easily stored and transported.
  • the framework of the containment device provides a durable lightweight receptacle, defined by the dimensions of the erected four side walls, where each wall is formed by the scissors-type connection between respective rods 16. Residing within these walls is canopy 14, which serves as the receptacle for hazardous materials. Because canopy 14 receives and retains hazardous chemicals, it is preferred that it be constructed of a chemically resistive fabric or material.
  • Canopy 14 preferably attaches to at least those hubs 12 positioned at the upper face of the framework in the erect configuration. Although canopy 14 may permanently attach to these hubs 12, it is preferred that canopy 14 removably attach to hubs 12, by any conventional means, including, but not limited to clips, snaps, buttons, velcro, or adhesives.
  • the containment device provides an easily deployable unit, which may be articulated to its erect configuration by a single individual, regardless of technical background. Once erected, the unit enjoys great mobility, because it is constructed of lightweight, durable materials, such as lightweight metals, plastics or composite materials. Indeed, a single individual may effectively transport and manipulate the unit at the spill site to best contain spills of hazardous materials (i.e. sliding the erect unit beneath a tanker or other similar equipment).
  • various modifications can be made to the containment device of the present invention without departing from the scope and spirit of the invention.
  • the canopy section of the containment device permits a variety of modifications that increase the adaptability as well as the strength of the receptacle of the containment device.
  • the containment device may enjoy increased adaptability and strength in its expanded configuration by affixing various support structures into the receptacle region formed by the rectangular prism.
  • liner 22, preferably disposable may be affixed into receptacle 23 to provide added strength as well as adaptability, because liner 22 may be easily removed and replaced.
  • Liner 22 may be affixed to the containment device using various methods, including clips, buttons, snaps, hook and loop fasteners, or adhesives.
  • wedge shaped insert 26 of preferably hard material may be attached to the bottom of canopy 14 to protect canopy 14 from heavy objects placed in the containment device.
  • a preferred configuration of wedge shaped insert 26 is illustrated in Figures 4 and 5.
  • the containment device may be used in conjunction with hard fastening clips 50 that adhere to the side walls of the containment device in the open erect configuration, as illustrated in Figure 10. These clips 50 reinforce the connection between hubs 12, canopy 14, and liner 22.
  • the containment device may be partitioned to retain differing types of hazardous material.
  • the containment device may include receptacle 40 which is compartmentalized, such that when the containment device is deployed into its erect configuration there exists one or more receiving areas encompassed within the side walls of the unit.
  • the receptacle may include one or more separate canopies.
  • the containment device in its open erect configuration, includes inner 41 and outer 42 compartments, each capable of receiving and retaining hazardous materials, as illustrated in Figure 7.
  • the receiving capabilities of the containment device may be easily expanded by attaching one or more units adjacent one another, preferably joined at the hub sections, as illustrated in Figures 9 and 12.
  • the rods may include a telescoping member that permits extension in the length of the rods, thereby, increasing the receiving volume of the receptacle region.
  • hazardous material resident in the receptacle may be easily removed by a conduit or other conveying means attached to one or more outlets 44 or drain holes of canopy 14, as illustrated in Figure 8.
  • a conduit or other conveying means attached to one or more outlets 44 or drain holes of canopy 14, as illustrated in Figure 8.
  • Such removal capabilities increases the capacity of the containment device, because it permits draining of the receptacle region while simultaneously allowing the receptacle region to continue to receive hazardous materials.
  • the adaptability of the containment device may be further manipulated by controlling the vertical dimensions of the unit once erected. For example, to adjust the height of the erect containment device, adjustable straps 52, as depicted in Figure 11, may be affixed to opposing hubs 12, 18 of the device.
  • These straps 52 may include a becket latch or other fastening system that allows the user to adjust the height of one or more corners of the containment device by adjusting the length of each strap 52.
  • dead stop 30 may be placed between opposing hubs 12, 18 of the containment device, as illustrated in Figure 3. In essence, dead stop 30 prevents the corners of the containment device from compacting in its vertical height beyond a predetermined distance.
