The entire contents of both U.S. 62/080,284 and U.S. 61/906,034 are expressly incorporated herein by the reference.

FIELD OF INVENTION

This invention relates to barriers, and more particularly to reusable water-permeable barriers positioned around perimeters of raised work areas to prevent injuries to persons below the raised work areas caused by falling debris and erosion filtration.

BACKGROUND OF THE INVENTION AND DESCRIPTION OF RELATED ART

Containment of construction debris around construction sites—whether solid or liquid—is required to protect both the physical environment and the health and safety of those in and near the construction site.
“Toe boards” are known in the construction industry and are required to contain debris and to prevent debris from falling from raised work areas, such as floor decks of multi-story buildings during construction. “Toe boards” generally consist of 1″×4″×10′ pieces of wood interconnected end-to-end and positioned around a perimeter of the raised work area spacedly adjacent the edges of the floor deck. Toe boards are also used around openings defined in raised work areas such as elevator shafts, stairwells, and similar locations where there are unprotected edges adjacent a vertical drop.
One recognized drawback to known wood toe boards is the difficulty of reusing the toe boards after the construction is complete and the toe boards are removed. Nails, screws and similar types of fasteners are typically used to interconnect the wood toe boards together and also to interconnect angulated braces to one side portion of the toe boards to cause the toe boards to “stand” on edge so they provide the vertical height necessary to prevent items and debris from passing thereover to fall from the raised work area. Such fasteners permanently damage end portions of the wood toe boards, the fasteners need to be removed after use, and the fastener damage may prevent secure end-to-end attachment after a first use. Further, the angulated braces prevent wood toe boards from being efficiently stored when not in use, because the angulated braces prevent the toe boards from stacking adjacent one another. Further still, wood has the tendency to absorb moisture, which makes it soft and heavy and subject to carrying molds, spores, and other contaminants that may stain concrete and other valuable construction surfaces and may cause illnesses or allergies or the like to workers. As a result, wood toe boards have significant drawbacks for the construction field.
Our reusable water-permeable toe tube for construction perimeters overcomes and resolves various of the aforementioned drawbacks to known wood toe boards. Our toe tube is comprised of an elongated tube formed of plasticized woven mesh product carrying a particulated fill to provide mass and dimension.
Our toe tube is an improvement over wood toe boards because it is flexible, reusable, and may also be used to filter and strain fluids such as, but not limited to, drainage water and runoff.
It is known to use ground-up particulated rubber to form building materials, sometimes in combination with other materials. For example, Kubicky, US 2002/0147255 discloses a mixture of scrap tire rubber in combination with a filler and binder used to build environmentally friendly structures, and Roth, U.S. Pat. No. 6,972,144 discloses a composite structural material that can be made to replace wooden boards. Also disclosed are fence posts (Silva, US 2005/0208264); structural members (Ingram, US 2005/0123701); railroad ties (Hansen, U.S. Pat. No. 6,766,963); building panels (Ciao, U.S. Pat. No. 5,704,178); and post and/or pole segments (Nevin, U.S. Pat. No. 5,675,956). However, these known devices are rigid and/or form central reinforcing members. None of these known devices is flexible, moldable, or water-permeable.
Floating tubular barriers to prevent the spread of oil (Schiwek, U.S. Pat. No. 6,017,452) are known, however, these barriers are typically filled with air and have neither the mass nor weight for use as a construction barrier
What is needed is a multi-use reusable barrier that can be placed around a perimeter of a construction site to contain solid materials from escaping but that will allow fluids to pass therethrough such that flooding is avoided so as to be used for run-off control and erosion control.
Some or all of the drawbacks and problems explained above, and other drawbacks and problems known and not yet recognized, may be helped or solved by our invention shown and described herein. Our invention may also be used to address other problems not set out herein or which become apparent later. The future may also bring to light unknown benefits that may, in the future, be appreciated from the novel invention shown and described herein.
Our invention does not reside in any single one of the identified features individually, but rather in the synergistic combination of all of its structures, which give rise to the functions necessarily flowing therefrom as hereinafter specified and claimed.

BRIEF SUMMARY OF THE INVENTION

A multi-use reusable toe tube safety apparatus to prevent construction debris from falling from edges of raised work areas provides an elongate water-permeable tubular body defining a medial chamber and having opposing closed end portions, each end portion and the body carrying releasable attachment means. The tubular body is filled with a particulated fill material.
In providing such a toe tube safety apparatus, it is:
a principal object to provide a safety apparatus for placement around the perimeter of raised work areas to prevent debris from falling there-from.
a further object to provide a toe tube that is reusable.
a further object to provide a toe tube that is fluid permeable.
a further object to provide a tube that satisfies OSHA standards.
a further object to provide a toe tube having tabs at opposing end portions that taper and carry a grommet for releasable interconnection with adjacent toe tubes.
a further object to provide a toe tube having “overlap tabs” to facilitate overlap of the toe tubes rather than end-to-end alignment.
a further object to provide a toe tube filled with particulated material having a diameter of approximately 1 inch or less.
a further object to provide a toe tube filled with particulated recycled tires.
a further object to provide a toe tube that may be manufactured in any length and in any color.
a further object to provide a safety device that may be adjustably positioned without a need to cut the safety device to size.
a further object to provide a toe tube to eliminate soil contamination caused by construction debris and chemicals seeping or leeching into soils in and around construction sites, including lay-down areas around reinforced steel, rebar, and treated timbers; portable toilets; and saw yards.
a still further object to provide a toe tube filled with crushed seashells and diatomaceous earth, or carbon filtering spheres for use as run-off barriers and erosion control, which will filter moisture and retain chemicals.

Our toe tube 1 generally provides an elongate body 4 having a first end portion 11 and a spaced apart second end portion 12 and defines a medial chamber 32 extending between the first end portion 11 and the second end portion 12. The body 4 is preferably formed of flat sheets of woven fabric material 31, which are sewn into a tube 4 and sealed at the first and second end portions 11, 12 respectively. Particulated fill 36 is carried within the medial chamber 32.
The body 4 is preferably formed of a fabric material 31 that is durable, flexible, non-staining, environmentally friendly, and water-permeable such as, but not limited to, a plasticized woven product.
The fill 36 is particulated to allow the body 4 to be bendable, flexible and has a density and mass to provide the body a generally consistent diameter 40 of approximately 3 1/2 inches to 6 1/2 inches. Diameter 40 ensures that a vertically uppermost portion of the body 4 is sufficiently vertically above a supporting surface to comply with local, state, and federal standards for similar construction safety barriers and to prevent passage of debris there-over. The fill 36 is anticipated to be ground rubber, ground to a diameter of approximately one inch or less per piece. It is envisioned that recycled tires could be the source of the fill 36, although other materials and processes may likewise provide the required characteristics of the fill 36.
In the preferred embodiment, the first and second end portions 11, 12 respectively are formed into tabs 3, 10 by compressing diametrically opposed portions of the fabric material of the body 4 radially inwardly so that opposing inner portions of the fabric material are in direct physical contact with one another. The contacting fabric portions are folded inwardly to a truncated taper and then permanently interconnected to one another such as with stitching, riveting and/or gluing.
Tab 3 at the first end portion 11 and tab 10 at the second end portion 12 each carry at least one grommet 2 defining a medial through hole which allows a plurality of the toe tubes 1 to be interconnected end-to-end. (FIG. 3).
Overlap tabs 6, 7 are permanently affixed, such as by stitching, to an exterior surface 33 of the body 4 at spacedly arrayed positions thereon, preferably spacedly inward of the first end portion 11 and the second end portion 12. Grommets 2 are carried by the overlap tabs 6, 7 to allow plural bodies 4 to be interconnected in an overlapping fashion. (FIG. 4).
Exterior surface 33 of the body 4 may be any color although it is envisioned that “Construction Orange”, which is commonly referred to as Phizatec #426 may be a standard color.
In a further embodiment, the fill 36 may be specially designed and engineered to selectively absorb certain fluids but not others, such that hazardous fluids would be absorbed but non-hazardous fluids may pass through. Diatomaceous earth is particularly contemplated as a fill 36.
Having described the structure of our toe tube safety apparatus, its operation may be understood.
Assuming use at a construction site wherein a multi-story building is being constructed, and above-grade floor decks are not enclosed with exterior walls, a user would place a plurality of toe tubes 1 on the raised work area spacedly inward from outer edges of the floor deck, and also around unprotected holes in the floor deck, such as elevator shafts and stairwells.
A fastener (not shown) such as, but not limited to a cable tie, zip tie, or a wire may be used to interconnect plural toe tubes 1 in an end-to-end configuration (FIG. 3) or an overlapping configuration (FIG. 4).
The plurality of toe tubes 1 may be aligned in an end-to-end orientation such that a tab 3, 10 of one toe tube 1 is proximate to a tab 3, 10 of an adjacent toe tube 1. The toe tubes 1 and the tabs 3, 10 are manually manipulated so that the grommets 2 (shown atop each other) carried by the tabs 3, 10 are concentrically aligned so that a fastener (not shown) may be simultaneously inserted through the hole defined by both aligned grommets 2. The fastener (not shown) is thereafter secured in its customary fashion to prevent inadvertent movement of the toe tubes 1 such that an “opening” or “break” in the otherwise continuous safety barrier is formed. The process is repeated interconnecting the tabs 3, 10 of adjacent toe tubes 1 extending continuously around the perimeter of the floor deck.
In locations where it is impractical, difficult, or impossible to interconnect adjacent toe tubes 1 in an end-to-end orientation, (FIG. 3), such as where the toe tubes 1 are too long for end-to-end attachment, the toe tubes 1 may be interconnected using the overlap tabs 6, 7 (FIG. 4) using a similar fastener and a similar process.
The foregoing description of our invention is necessarily of a detailed nature so that a specific embodiment of a best mode may be set forth as is required, but it is to be understood that various modifications of details, sizes, and rearrangement, substitution and multiplication of the parts may be resorted to without departing from its spirit, essence, or scope.
Having thusly described our invention, we file this Utility patent application.
