Abstract
A portable containment (10) is illustrated for field use in containing pesticides and other toxic chemicals and the like. Containment (10) includes a floor (12) and integral side walls (16, 18, 20, 22). Resilient side braces (A), bracing straps (B), and compressible top braces (C), provide resiliency so that the upstanding walls deform to allow a wheeled vehicle or aircraft (13) to roll onto and off of the containment in the field. Elastic corners (D) allow the side walls and corners to be deformed outwardly or inwardly without tearing or damage of the corners or upstanding walls.
Claims30
A portable containment for containing spilled material and preventing environmental contact, comprising:
- a floor composed of sheet material;
- deformable upstanding wall means composed of sheet material integrally connected to said floor for containing the spilled material in cooperation with said floor;
- and
- a plurality of vertically-extending resilient side braces attached to said wall means and spaced around a periphery of said wall means to brace said wall means in an upright position while allowing said wall means to recover resiliently and return to said upright position after collapse under force.
A portable containment for containing a spilled material and preventing environmental contact, comprising:
- floor means;
- wall means for containing the spilled material in cooperation with said floor means;
- first wall bracing means extending vertically along said wall means for yieldingly bracing said wall means in an upright position;
- second wall bracing means having portions extending horizontally along said wall means separate from said first wall bracing means for yieldingly bracing said wall means in cooperation with said first wall bracing means maintaining said wall means in said upright position;
- and
- said first and second wall bracing means allowing said wall means to collapse vertically under a force while allowing said wall means to recover resiliently and return to said upright position after said force is removed.
A portable containment for containing a spilled material and preventing environmental contact, comprising:
- a floor composed of flexible sheet material;
- a plurality of upstanding walls composed of flexible sheet material and integrally connected to said floor to contain the spilled material in cooperation with said floor;
- resilient brace means carried by said walls for bracing said walls and maintaining said walls in an upright position while allowing said walls to collapse under force when run over by a vehicle and resiliently return to said upright position after said force is removed;
- and
- an elastic corner means formed adjacent ends of said upstanding walls which includes a corner gusset formed by said sheet material, and elastic means retracting said corner gusset and allowing said corner gusset to expand when said upstanding walls are deformed.
