BACKGROUND OF THE INVENTION - FIELD OF THE INVENTION This invention relates to barriers for isolating and warning of hazardous conditions and separating foot traffic from maintenance or clean-up operations .

BACKGROUND OF THE INVENTION - PRIOR ART The ability of a business or employer to effectively maintain a safe environment for workers, customers, and the general public is an important duty that can prevent costly health and legal implications. Separating foot traffic from floor maintenance, clean-up, construction, or other operations with potential hazards is one way to prevent these costs. This is especially true in environments such as hospitals, airports, 24-hour supermarkets, bus terminals, restaurants, schools, housekeeping industries, and various businesses utilizing industrial or chemical processes.

Although various devices are available for containing or warning of hazardous conditions, few offer an effective combination of containing hazards such as liquid spills while also warning and isolating the hazards from potentially unwary or distracted people passing through the area.

Commonly available warning devices include floor warning signs similar to those disclosed in U.S. Pat. Nos. 6,003,257 to Stokes (1999), 6,131,320 to Eberle et al. (2000), and 7,013,590 to Bell et al. (2006). Devices for those disclosed in U.S. Pat. Nos. 4,031,676 to Dally (1977), 5,236,281 to Middleton (1993), 5,605,416 to Roach (1997, 5,820,297 to Middleton (1998), and 6,334,736 to Johnson et al. (2002), and combination signs and barriers such as that disclosed in U.S. Pat. No. 6,135,423 to Johnson. Even though devices are available for isolating and/or containing hazardous work areas such as spill zones, many of them suffer from one or more of the following disadvantages:

(a) They are primarily designed for use in an industrial setting where a large amount of liquid might need to be controlled via a dike or by damming. (b) They fail to provide adequate barrier characteristics to warn and divert foot traffic. These characteristics include any type of warning sign or tape and any type of noticeable sign located near an average person's waist level.

(c) Even though they may have signs warning of a hazard, they do not provide an adequate barrier from foot traffic or for containment of liquids.

(d) They fail to provide for isolation or containment of liquids in a work or spill area.

(e) They provide at least one desirable feature such as spill containment, a warning sign, or an adequate barrier for foot traffic, but they fail to provide a combination of these desirable features.

(f) They are heavy, burdensome, and/or inconvenient to move or carry.

(g) They are not easy to store and/or take up excessive storage space, (h) They are difficult to set up and use.

(i) Their cost to manufacture and resulting purchase price may be considered to be too high when compared to products with similar functions.

The hazard isolation and warning barrier 11 can be made of a variety of materials such as plastic, rubber, metal, and foam (i.e., closed cell foam, soft flexible foam, foam rubber, polystyrene foam, polymer with fiberglass) . The preferred material is a hard, durable plastic.

165 The barrier 11 has a combination of straight pieces IOA and corner pieces 1OB. The pieces consist of a top surface 12, a bottom surface or undersurface 14, a first end 21, and a second end 25. The preferred cross section of the barrier pieces is a half octagon shape. However it can have different cross sections, such as triangular, rectangular, half circular,

170 etc., and different sizes.

In a preferred embodiment, the top surface 12 of the barrier has at least one warning pole hole 35 and at least one suction cup hole 54. Furthermore, the first end 21 and second end 25 of a barrier piece may have a combination of a flat surface, male connector 56, and/or a female connector 58. In the

175 preferred embodiment, the female connector 58 will be at the first end 21 and the male connector 58 will be at the second end 25, except if the piece is an end piece, in which case either the first or second ends will not have a male or female connector and instead will have a flat surface. The male connector 58 is a curve-shape extending from the second end 25 and the female connector

180 56 is an indention in the shape of the male connector 58 on the top surface 12 of the barrier piece, extending into the barrier piece from the first end 21. More generally, the male connector 58 extends from either a first end 21 or a second end 25, with either a flat surface or a female connector 56 being located at the opposite end of the piece. Also, the female connector 56

185 extends into the barrier piece from a first end 21 or a second end 25 with either a flat surface or a male connector 58 being located at the opposite end of the piece.

The barrier pieces have a hollow interior, with the bottom surface or undersurface 14 comprising the perimeter of the bottom area, adjacent to the 190 exposed surface 12 and sides 21 and 25, and which contacts a floor surface when a piece is lying with the exposed surface 12 facing away from the floor surface. Furthermore, the undersurface 14 has material layer 13 comprising a rubber gasket that covers and extends from the undersurface 14.

The warning pole holes 35 are sized for holding a warning pole 36. 95 Warning or caution tape 39 is attached to the warning poles 36 using attached rings 37, preferably being attached to the top of a warning pole 36 and running to the top of other warning poles 36 along the length of the barrier The suction cup holes 54 are sized for holding a suction cup control 200 device which comprises an activation ring and stem 50 and suction cup 52, shown in FIGS. 1 and 4. The ring portion of the ring and stem 50 is visible on the outer surface of the barrier 12 and the stem portion extends into the suction cup hole 54. A suction cup 52 is attached to the end of the portion of the stem that extends into the suction cup hole 54.

205

Operation - FIGS. 1, 4, 5

A user creates the barrier 11 by using a combination of straight pieces 1OA and corner pieces IOB with appropriate warning poles 36 and warning tape 39.

210 A user of the barrier should first clear any debris or liquids from the perimeter of the area to be isolated. Next, any number of straight pieces 1OA and corner pieces 1OB should be acquired and connected by attaching a first end 21 of one piece to a second end 25 of another piece. When connecting the pieces, the user should ensure that the first end 21 has

215 either a male connector 56 or a female connector 58 and the second end 25 has a corresponding female connector 58 or a male connector 56, respectively.

The male connector 56 should be placed into the female connector 58 to connect the two pieces. This process should be repeated until the desired containment area is isolated. The appropriate pieces are connected in such a 220 fashion as to allow the designated hazardous area to be separated from other areas via the barrier 11.

Next, the user should apply pressure to the barrier pieces 1OA and 1OB so that the material layer 13 will form a seal with or become contiguous to the floor surface. Furthermore, the suction cup control devices should be 225 activated by turning the activation ring and stem 50 which will cause the suction cup 52 to form a suction with the floor surface, holding the barrier in place and blocking the flow of liquid spills from escaping the controlled area.

Next, the warning poles 36 are inserted into the warning pole holes 35. 230 The warning tape 39 should then be attached to the warning poles 36 using attached rings 37, preferably at the top of the poles and running approximately parallel to and above the barrier pieces. The hazard area is now isolated and maintenance, clean up, fluid or chemical application, or other work in the isolated area may commence.
