Benefits of technology

[0013] The elongated tensile member can be moved between open and folded positions, wherein the tensile member subjects the expansive sheet of material to tension in the open position and maximizes its circumference. In the folded position, the tensile member can be folded to provide multiple loops.

Problems solved by technology

Such devices can leak materials that are hazardous to the environment such as oil, gasoline, power steering fluid, grease, gear oil, brake fluid and the like.

Embodiment Construction

[0021]FIGS. 1-5 show a preferred embodiment of the apparatus of the present invention designated by the numeral 10 in FIG. 1. Spill control apparatus 10 is shown in FIG. 4 being positioned under a motor vehicle 11. In FIG. 5 it is shown positioned under a forklift 12. The apparatus 10 of the present invention can be used to contain hazardous fluids that may leak or drip from any other vehicle such as a truck, van, ambulance or other emergency, work, passenger, or rescue vehicle.

[0022] The apparatus 10 includes a layered center 13 surrounded by edging material 15. The layered center 13 is comprised of a porous, absorbent layer 14a and a fluid impervious layer 14b. The absorbent material 14a is preferably a sheet of material that absorbs substances that fall upon its upper surface 28. Examples of suitable absorbent material are polypropylene and polypropylene-universal. The layer 14a can be any material that can absorb and hold fluids that typically drip or leak from a motor vehicle....

Abstract

A portable chemical spill control device includes an expansive sheet of material (preferably multiple layers that include at least one layer of absorbent material) and having upper and lower surfaces and a periphery that defines a circumference. The sheet of material is of a material that is resistant to fluid attacks so that spills deposited upon the upper surface are contained on the upper surface. A peripheral bead includes a foldable portion that extends around the expansive sheet of material, the bead including an elongated tensile member and a folded portion that holds the elongated tensile member to the absorbent sheet of material. A connection joins the peripheral bead to the expansive sheet of absorbent material in a configuration that envelops the tensile member with the foldable portion. The elongated tensile member can be moved between open and folded positions wherein the tensile member subjects the expansive sheet of material to tension in an open position that maximizes its circumference, and wherein in the folded position the tensile member folds to provide multiple loops.
