This invention relates generally to oil absorbent mats for use in industrial, commercial, garage, workshop or manufacturing facilities and, more particularly, to a system of interlocked absorbent mats for placement on a floor.
Oil, grease, coolant and/or other fluids may accumulate on the floor around machinery, work tables, racks, and the like in industrial, commercial, garage, workshop, or manufacturing facilities. Absorbent mats may be used to absorb oil, grease, coolant and/or other fluids but are typically simply placed on the floor and are free to move around. Accordingly, such mats can bunch up or develop ridges creating a trip hazard. Such mats can also slip as persons walk over them, thereby defeating or minimizing any benefit that they provide by absorbing oil, grease, coolant or other fluids.
The present invention utilizes a system of absorbent mats that are secured or interlocked to one another and secured to the floor of an industrial, commercial, garage, workshop, or manufacturing facility (all of which are referred to herein as a “manufacturing facility”). The system as contemplated by the present invention covers large areas of a facility at which the system is installed, including heavily traveled walkways. Accordingly, one embodiment of the absorbent floor system is a complex system of interlocking absorbent mats. The absorbent mats are secured to the floor and to one another to provide a stable and secure walking surface. The absorbent mats may be layered to accommodate high oil leaking areas and/or to reduce and/or eliminate the flow of oil, grease, coolant and/or other fluids into undesired areas. The absorbent floor system may wick oil, grease, coolant and/or other fluids throughout the entire floor to provide a safe walking zone for manufacturing facilities. The absorbent floor system may also prevent such oil, grease, coolant and/or other fluids from propagating to areas of the facility floor that are not covered by the absorbent floor system such as visitor walkways, forklift driveways, truck driveways, stairs, etc. Individual absorbent mats may be swapped out as they become fully saturated prior to a full reinstallation. When the absorbent mats are removed from the floor of the facility, they may be cleaned or recycled.
Briefly, therefore, one embodiment of the present invention is directed to an absorbent floor system for absorbing oil, grease, coolant and/or other fluids comprising a population of single sided hook fasteners adhered to a floor of a manufacturing facility, and a population of absorbent mats wherein at least one of the population of absorbent mats is secured directly to the population of single side hook fasteners.
Another embodiment of the present invention is directed to an absorbent floor system for absorbing oil, grease, coolant and/or other fluids comprising a population of single sided hook fasteners adhered to a floor of a manufacturing facility; a population of absorbent mats wherein at least one of the population of absorbent mats is secured directly to the population of single side hook fasteners; and a liner placed on the floor under at least one of the population of absorbent mats.
Another embodiment of the present invention is directed to an absorbent floor system for absorbing oil, grease, coolant and/or other fluids wherein at least one of the population of absorbent mats at least partially overlaps another one of the population of absorbent mat to form a layer of absorbent mats.
Another embodiment of the present invention is directed to an absorbent floor system for absorbing oil, grease, coolant and/or other fluids wherein overlapped absorbent mats are secured to one another by double sided hook fasteners.
Another embodiment of the present invention is directed to an absorbent floor system for absorbing oil, grease, coolant and/or other fluids comprising a population of single sided hook fasteners adhered to a floor of a manufacturing facility wherein the population of single sided hook fasteners define at least one mat-hook-floor line of the absorbent floor system; a population of absorbent mats comprising at least one inner absorbent mat and at least one outer most absorbent mat wherein at least one outer most absorbent mat is secured directly to at least one of the population of one or more single sided hook fasteners and wherein the at least one inner absorbent mat is placed under the at least one outer most absorbent mat and is secured to the at least one outer most absorbent mat by a double sided hook fastener
Another embodiment of the present invention is directed to a method of installing an absorbent floor system for absorbing oil, grease, coolant and/or other fluids comprising a population of absorbent mats comprising the steps of: placing a population of absorbent mats on the floor of a manufacturing facility; adhering a population of single sided hook fasteners to the floor, wherein the population of single sided hook fasteners define a mat-hook-floor line of the absorbent floor system; and securing one or more of the population of absorbent mats directly to the population of single sided hook fasteners.
Another embodiment of the present invention is directed to a method of installing an absorbent floor system for absorbing oil, grease, coolant and/or other fluids comprising a population of absorbent mats comprising the steps of: placing inner absorbent mats on a floor of a manufacturing facility and/or partially or completely overlapping any previously placed inner absorbent mats, wherein the inner absorbent mats may be a standard absorbent mat, a leaner absorbent mat, a pre-site custom cut absorbent mat, a pre-site custom cut walkway absorbent mat, and/or a most traveled walkway absorbent mat; placing outer most absorbent mats on the floor and/or partially or completely overlapping any previously placed inner or outer most absorbent mats, wherein the outer most absorbent mats may be a standard absorbent mat, a leaner absorbent mat, a pre-site custom cut absorbent mat, a pre-site custom cut walkway absorbent mat, and/or a most traveled walkway absorbent mat; adhering a population of single sided hook fasteners to the floor wherein the population of single sided hook fasteners define a mat-hook-floor line of the absorbent floor system; and securing the outer most absorbent mats directly to the population of single sided hook fasteners.
These and other features, aspects and advantages of the invention will become more fully apparent from the following detailed description, appended claims, and accompanying drawings, wherein the drawings illustrate features in accordance with exemplary embodiments of the present invention, and wherein:
Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the objects listed thereafter and equivalents thereof as well as additional objects. All numbers expressing measurements and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.”
Absorbent mats are used in absorbent floor systems of the invention. In one embodiment, all mats of the absorbent floor system include the same absorbent material. In other embodiments, the absorbent materials differ among the mats of an absorbent floor system. For example, absorbent materials may be selected based on a variety of factors including, but not limited to, the quantity and/or flow of oil, grease, coolant and/or other fluids to be absorbed; the length of time that the absorbent floor system is to be in service prior to a reinstall; the level of actual or anticipated foot traffic over the absorbent floor system; available sizes of absorbent mats; the size of the area to be covered; whether the area to be covered is sloped or level, and/or other factors. Absorbent mats of an absorbent floor system may comprise a needle-punched polypropylene-synthetic blend material. In certain embodiments, absorbent mats of an absorbent floor system comprise at least 20 percent polypropylene. In certain other embodiments, absorbent mats of an absorbent floor system comprise at least 50 percent polypropylene. In yet other embodiments, absorbent mats of an absorbent floor system comprise at least 60 percent polypropylene. In yet other embodiments, absorbent mats of an absorbent floor system comprise about 100 percent polypropylene. In certain embodiments, therefore, absorbent mats of an absorbent floor system comprise from about 20 to 100 percent polypropylene and from about zero to about 80 percent other synthetic or natural materials, wherein the other synthetic materials may include, but are not limited to, polyester, polyethylene, rubber, and/or other synthetic or natural materials suitable for use in an absorbent mat, e.g., because such materials exhibit characteristics of absorbency, durability and/or flexibility (defined as how easily the mat can be folded, rolled, and/or bent) similar to polypropylene or otherwise suitable for use in an absorbent mat. Such other synthetic or natural materials may also include fire retardants, UV stabilizers or inhibitors, colorants, binders, adhesives, antistatic materials, antimicrobial materials, and/or other additives that provide qualities useful for absorbent mats of absorbent floor systems of the invention.
For example, in one embodiment, an absorbent mat of an absorbent floor system comprises about 20 percent polypropylene and about 80 percent other synthetic or natural materials. In another embodiment, an absorbent mat of an absorbent floor system comprises about 30 percent polypropylene and about 70 percent other synthetic or natural materials. In other embodiments, an absorbent mat of an absorbent floor system comprises (i) about 40 percent polypropylene and about 60 percent other synthetic or natural materials; (ii) about 50 percent polypropylene and about 50 percent other synthetic or natural materials; (iii) about 60 percent polypropylene and about 40 percent other synthetic or natural materials; (iv) about 70 percent polypropylene and about 30 percent other synthetic or natural materials; (v) about 80 percent polypropylene and about 20 percent other synthetic or natural materials; (vi) about 90 percent polypropylene and about 10 percent other synthetic or natural materials; (v) about 100 percent polypropylene (it being understood that a mat comprising about 100 percent polypropylene absorbent mat may also include other synthetic or natural materials such as fire retardants, UV stabilizers or inhibitors, colorants, binders, adhesives, antistatic materials, antimicrobial materials and/or other materials suitable for use in absorbent mats of absorbent floor systems).
In a preferred embodiment, the absorbent mat is a needle punched and heat treated industrial fabric having a composition of about 99.65 percent polypropylene and about 0.35 percent carbon black colorant bound in the polymer matrix. Such absorbent mat may be supplied by Dalco Nonwovens, LLC of Conover, N.C. under the product names I100-BLK160-144-150 or I100-HGY160-036-150.
Absorbent mats of absorbent floor systems of the invention may be further defined by the weight of the mat. The weight of an absorbent mat is defined on a weight per area basis (e.g., ounces per square yard). For example, an absorbent mat may weigh from about 8 ounces to about 30 ounces per square yard (e.g., about 8 ounces, about 10 ounces, about 12 ounces, about 14 ounces, about 15 ounces, about 16 ounces, about 18 ounces, about 20 ounces, about 22 ounces, about 24 ounces, about 26 ounces, about 28 ounces, or about 30 ounces per square yard). In another embodiments, an absorbent mat of an absorbent floor system weighs from about 10 ounces to about 20 ounces per square yard. In yet another embodiment, an absorbent mat of an absorbent floor system weighs about 15 ounces per square yard.
In addition to the variety of material types and weights of absorbent mat contemplated by various embodiments, absorbent mats of varying widths may be utilized in the absorbent floor system. In one embodiment, absorbent mats of an absorbent floor system vary in width from about 2 feet to about 13 feet. For example, one or more absorbent mats are about 2 feet wide, about 3 feet wide, about 4 feet wide, about 5 feet wide, about 6 feet wide, about 7 feet wide, about 8 feet wide, about 9 feet wide, about 10 feet wide, about 11 feet wide, about 12 feet wide, and/or about 13 feet wide. Absorbent mats may be provided from the manufacturer in 150 foot (50 yard) rolls and cut to any desired length and/or width; absorbent mats may be otherwise provided.
Leaner absorbent mats 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h are placed around and under objects 11a and 11b and overlap standard absorbent mat 12. Leaner absorbent mats 14a, 14b, 14c, 14d, 14e, 14f, 14g, 14h are absorbent mats custom cut on site (i.e., the installation site) to allow the mat to lie substantially flat around and under an object adjacent to the mat, as described more fully below. A leaner mat may be provided on-site as a standard absorbent mat (e.g., in one of the sizes used commonly enough to justify pre-cutting mats to such sizes without consideration of information gathered during site evaluation and planning) or as a pre-site custom cut absorbent mat (described below). Other types of absorbent mats may be placed under objects 11a and 11b. Some embodiments of absorbent floor systems do not include leaner absorbent mats.
Absorbent mats 16a and 16b are pre-site custom cut absorbent mats that overlap leaner absorbent mats 14b, 14c, 14d and 14f, 14g, 14h, respectively, as described more fully elsewhere herein. In the embodiment of an absorbent floor system 10 illustrated on
In this embodiment, absorbent mats 18a and 18b are most traveled walkway mats 18a and 18b and are placed on the floor, wherein most traveled walkway mat 18a overlaps standard absorbent mat 12, leaner absorbent mats 14a, 14b, 14c, 14e, 14f and 14g, pre-site custom cut absorbent mats 16a and 16b, and pre-site custom cut walkway absorbent mats 17a and 17b, and wherein most traveled walkway mat 18b overlaps standard absorbent mat 12, leaner absorbent mats 14a, 14b, 14d, 14f and 14h, pre-site custom cut absorbent mat 16a and 16b, and pre-site custom cut walkway absorbent mats 17a and 17b, as described more fully elsewhere herein.
Most traveled walkway mat refers to a mat used in a high foot traffic or relatively high foot traffic portion of the area covered by an absorbent floor system. The significance of the designation of an absorbent mat of an absorbent floor system as a most traveled walkway mat is found primarily in installation of the system. As described in more detail below, according to a preferred method of installing an absorbent floor system, a most traveled walkway absorbent mat is the first mat to be secured to the floor. Furthermore, a most traveled walkway mat is often placed immediately adjacent to non-work area walkways, e.g., a walkway used for visitors to a factory floor. A most traveled walkway absorbent mat may be provided as a pre-site custom cut absorbent mat or a standard absorbent mat. In some embodiments, a most traveled walkway absorbent mat may also be a leaner absorbent mat. Other embodiments include no most traveled walkway mats.
Although pre-site custom cut walkway absorbent mats 17a and 17b and most traveled walkway absorbent mats 18a and 18b are shown as the outer most absorbent mats, in other embodiments, pre-site custom cut walkway absorbent mats 17a and 17b and most traveled walkway absorbent mats 18a and 18b may be inner absorbent mats. In one embodiment, for example, a most traveled walkway absorbent mat or pre-site custom cut walkway absorbent mat may run through an inner region of an absorbent floor system and be surrounded by a population of underlapping mats. In another embodiment, for example, a most traveled walkway absorbent mat or pre-site custom cut walkway absorbent mat may run through the middle of an absorbent floor system and be surrounded by a population of underlapping mats.
All absorbent mats 12, 14a, 14b, 14c, 14d, 14e, 14f, 14g 14h, 16a, 16b, 17a, 17b, 18a and 18b may be made of the same material, e.g., 15 ounce weight of 50 percent polypropylene and 50 percent other natural or synthetic materials. Alternatively, absorbent mats 12, 14a, 14b, 14c, 14d, 14e, 14f, 14g 14h, 16a, 16b, 17a, 17b, 18a and 18b may be made of different materials, e.g., in one embodiment standard absorbent mat 12 and leaner absorbent mats 14a, 14b, 14c, 14d, 14e, 14f, 14g and 14h are made of a 16 ounce weight of about 100 percent polypropylene; and pre-site custom absorbent mats 16a and 16b, pre-site custom walkway absorbent mats 17a and 17b, and most traveled walkway absorbent mats 18a and 18b are made of a 20 ounce weight of 60 percent polypropylene and 40 percent other natural or synthetic materials. Other variations of weights and blends as described herein can be used for absorbent mats of embodiments of the absorbent floor system. In certain embodiments, absorbent mats with a higher ounce weight and/or a higher percentage of polypropylene are selected for areas expected to receive higher amounts of oil, grease, coolant and/or other fluids and absorbent mats with a lower weight and/or lower percentage of polypropylene are selected for areas expected to receive smaller amounts of oil, grease, coolant, and/or other fluids, such as areas expected to receive only light mistings of such fluids.
In some embodiments of an absorbent floor system, multiple layers of absorbent mats are provided, e.g., an additional absorbent mat (not shown) may be placed above or below all or part of standard absorbent mat 12, leaner absorbent mats 14a, 14b, 14c, 14d, 14e, 14f, 14g and 14h, pre-site custom cut absorbent mats 16a and 16b, pre-site custom cut walkway absorbent mats 17a and 17b, and/or most traveled walkway absorbent mats 18a and 18b. The additional layers of absorbent mats may be placed in areas of high usage or high flows of oil, grease, coolant and/or other fluids and these additional absorbent mats may or may not be secured to any overlapping absorbent mats. The multiple layers of absorbent mats may provide cushioning for persons walking on the absorbent floor system 10 such that a separate cushion layer is not required.
Absorbent floor system 10 further comprises single sided hook fasteners 22 and double sided hook fasteners 24. The outer most absorbent mats, which as shown in
In some embodiments of absorbent floor systems of the present invention, absorbent mats of an absorbent floor system are secured or attached to the floor of the manufacturing facility or are secured to or interlocked with other absorbent mats using the hook fastener portion of a hook-and-loop type fastener (e.g., Velcro®-brand). Preferred materials for absorbent mats of absorbent flooring systems of the invention function as the loop portion of a hook-and-loop fastener and, accordingly, the hook fastener portion connects directly to the absorbent mats of such embodiments of absorbent flooring systems. In other embodiments, the loop fastener portion may be secured to an absorbent mat to permit an absorbent mat to be secured to the floor or underlying mat via a hook fastener.
Heavy duty hook fasteners are preferred. In one example embodiment, the hook fastener is supplied by Grimco Inc. of Fenton, Mo. Hook fasteners of varying widths may be utilized in the absorbent floor system. In one embodiment, for example, the hook fasteners may be about vary in width from about 0.5 inches to about 3.0 inches (e.g., about 0.5 inches wide, about 0.75 inches wide, about 1.0 inch wide, about 1.25 inches wide, about 1.5 inches wide, about 1.75 inches wide, about 2.0 inches wide, about 2.25 inches wide, about 2.5 inches wide, about 2.75 inches wide, about 3.0 inches wide). In other embodiments, the hook fasteners may vary in width from about 0.75 inches to about 1.5 inches. In yet another embodiment, the hook fasteners are about 0.75 inches wide. In yet another embodiment, the hook fasteners are about 2.0 inches wide. In yet another embodiment, the hook fasteners are more than 3.0 inches wide. Typically, the hook fasteners are provided in 75 feet (25 yard) rolls; however the hook fasteners may be cut to any desired length. In certain embodiments, for example, the hook fasteners may be about 3.0 inches in length or longer (e.g., about 3.0 inches, about 6.0 inches, about 12 inches, about 18 inches, about 2 feet, about 6 feet, about 12 feet, about 24 feet, about 50 feet, or about 75 feet).
In certain embodiments, as shown in FIG. B, single sided hook fasteners 22 comprise a substantially smooth first surface (e.g., a bottom) 22′ and a second surface comprising a population of hooks (e.g., a top) 22″. Single sided hook fasteners may be supplied with an adhesive on the first surface that permits securing of the single sided hook fastener to a floor 28. In other embodiments, the first surface of a single sided hook fastener may be adhered to a floor using a variety of adhesives applied to the first surface and/or the floor 28 during installation of the absorbent floor system including, but not limited to, rubber cement, epoxy, cyanoacrylate, etc. In yet other embodiments, single sided hook fasteners may be secured to the floor 28 using a variety of means including, but not limited to screws, nails, rivets, etc.
In one embodiment, as shown in
As illustrated in
In this particular embodiment, the single sided hook fasteners 22a-22d are not placed right at the outer edges of outer most absorbent mats, wherein the outer most absorbent mats as shown in
The extension of the absorbent mats beyond the mat-hook-floor lines and the mat-hook-mat lines is shown in more detail in
If single sided hook fastener 222 was placed so that first edge 2221 coincided with first edge 2181 of the most traveled walkway absorbent mat 218 the combined thickness of the single sided hook fastener 222 and the most traveled walkway absorbent mat 218 might be high enough to cause someone to trip. Accordingly, single sided hook fastener 222 may be placed under most traveled walkway mat 218 such that first edge 2181 of most traveled walkway absorbent mat 218 extends a sufficient distance (y) beyond first edge 2221 of single sided hook fastener 222 so as to allow the first edge 2181 of most traveled walkway absorbent mat 218 to lie directly on the floor so that there is a gentle transition in thickness from the thickness of the most traveled walkway absorbent mat 218 to the combined thickness of the most traveled walkway absorbent mat 218 and the single sided hook fastener 222. This may reduce or eliminate potential tripping points. In some embodiments, the distance (y) from first edge 2181 to first edge 2221, and thus from the mat-hook-floor line, is about 0.125 inches. In other embodiments distance (y) is from about 0.125 inches to about 1.0 inch (e.g., about 0.125 inches, about 0.25 inches, about 0.375 inches, about 0.5 inches, about 0.625 inches, about 0.75 inches, about 0.875 inches, or about 1.0 inch). In other embodiments, the distance (y) from first edge 2181 to first edge 2221, and thus from the mat-hook-floor line, is between about 0.25 inches and about 0.75 inches. In yet other embodiments, the distance (y) from first edge 2181 to first edge 2221, and thus from the mat-hook-floor line, is about 0.5 inches. In yet other embodiments, the distance (y) from first edge 2181 to first edge 2221, and thus from the mat-hook-floor line, is less than 0.125 inches. That is, in some embodiments, the first edge 2221 of single sided hook fasteners 222 may be placed at first edge 2181 of most traveled walkway absorbent mat 218 such that first edge 2221 and first edge 2181 are collinear. This may be done where there is little or no traffic crossing over single sided hook fasteners 222 such that there is a low likelihood of someone tripping.
If double sided hook fastener 224 were placed so that second edge 2242 coincided with second edge 2182 of the most traveled walkway absorbent mat 218 the combined thickness of the double sided hook fastener 224 and the most traveled walkway absorbent mat 218 might be high enough to cause someone to trip. Accordingly, double sided hook fastener 224 may be placed under most traveled walkway mat 218 and over pre-site custom cut mat 216 such that second edge 2182 of most traveled walkway absorbent mat 218 extends a sufficient distance (z) beyond second edge 2242 of double sided hook fastener 224 so as to allow the second edge 2182 of most traveled walkway absorbent mat 218 to lie directly on the pre-site custom cut absorbent mat 216 so that there is a gentle transition in thickness from the thickness of pre-site custom cut absorbent mat 216 to the combined thickness of most traveled walkway absorbent mat 218 and double sided hook fastener 224. This may reduce or eliminate potential tripping points. The distance (z) from second edge 2182 to second edge 2242, and thus from the mat-hook-mat line, may vary from about 0.125 inches to about 1.0 inch (e.g., about 0.125, about 0.25 inches, about 0.375 inches, about 0.5 inches, about 0.625 inches, about 0.75 inches, about 0.875 inches, or about 1.0 inch). In other embodiments, the distance (z) from second edge 2182 to second edge 2242, and thus from the mat-hook-mat line, may vary from about 0.25 inches to about 0.75 inches. In yet other embodiments, the distance (z) from second edge 2182 to second edge 2242, and thus from the mat-hook-mat line, may be about 0.5 inches. In yet other embodiments, the distance (z) from second edge 2182 to second edge 2242, and thus from the mat-hook-mat line, is less than 0.125 inches. That is, in some embodiments, the second edge 2242 of double sided hook fasteners 224 may be placed at second edge 2182 of most traveled walkway absorbent mat 218 such that second edge 2242 and second edge 2182 are collinear. This may be done where there is little or no traffic crossing over double sided hook fasteners 224 such that there is a low likelihood of someone tripping.

In certain other embodiments, one or more additional single sided hook fasteners may be used where there is not a significant number of overlapping mats. Accordingly, single sided hook fasteners and double sided hook fasteners can be used in any number and any location in the absorbent floor system depending on the requirements of the particular installation of the absorbent floor system to ensure that tripping points are minimized or eliminated.
Other absorbent floor systems do not include all types of absorbent mats of absorbent floor system 10. For example,
Another example embodiment of an absorbent floor system comprises pre-site custom cut absorbent mats, pre-site custom cut walkway absorbent mats, and most traveled walkway mats. Yet another embodiment comprises pre-site custom cut walkway absorbent mats and most traveled walkway absorbent mats. A further embodiment comprises standard absorbent mats, pre-site custom cut absorbent mats, pre-site custom cut walkway absorbent mats, and most traveled walkway absorbent mats. In other embodiments, an absorbent floor system comprises (1) standard absorbent mats, pre-site custom cut walkway absorbent mats, and most traveled walkway absorbent mats; or (2) standard absorbent mats, leaner absorbent mats, pre-site custom cut walkway absorbent mats, and most traveled walkway absorbent mats.
As will be understood, a most traveled walkway absorbent mat may be used in a location that is not actually the most traveled walkway of a particular site. Rather, “most traveled walkway mat” refers to a mat selected based on an actual or anticipated high traffic volume in all or part of the area covered by the mat.
While the absorbent mats are shown disposed at substantially right angles from each other, the absorbent mats can be placed at any angle and an absorbent floor system can form any shape on the floor including, but not limited to, triangular, rectangular, square, pentagonal, hexagonal, octagonal, circular, etc. Additionally, in certain embodiments, for example, the absorbent mats can be installed such that an absorbent floor system is irregular in shape. An absorbent floor system can be installed in any shape as desired or recommended in order to provide adequate absorption a variety of materials including, but not limited to, oil, grease, coolant, and/or other fluids.

A population of single sided hook fasteners 722 are adhered to the floor and the population of most traveled walkway mats 718a, 718b, 718c are secured to the population of single sided hook fasteners 722. Furthermore, a population of double sided hook fasteners 724 are used to secure most traveled walkway mat 718a to most traveled walkway mat 718c and to secure most traveled walkway mat 718b to most traveled walkway mat 718c. As shown, the population of walkway absorbent mats 717 and absorbent mats 716 are not secured to the population of most traveled walkway mats 718a, 718b, 718c. However, it should be understood from this disclosure that, in other embodiments, the population of walkway absorbent mats 717 and absorbent mats 716 may be secured to the population of most traveled walkway mats 718a, 718b, 718c using double sided hook fasteners 724. Furthermore, as shown in
The absorbent floor system can be deployed with various quantities of absorbent mats. The absorbent floor system preferably includes at least 5 absorbent mats, one or more of which are overlapping. In certain example embodiments, the absorbent floor system includes from 5 absorbent mats to about 20 absorbent mats, one or more of which are overlapping (e.g., about 5 absorbent mats, about 10 absorbent mats, about 15 absorbent mats, about 20 absorbent mats). In other example embodiments, the absorbent floor system includes 20 or more absorbent mats, most of which overlap at least one other absorbent mat of the system. In yet another example embodiment, the absorbent floor system includes 50 or more absorbent mats, most of which overlap at least one other absorbent mat of the system. In a further embodiment, the absorbent floor system includes 100 or more absorbent mats, most of which overlap at least one other absorbent mat of the system. In another embodiment, the absorbent floor system includes 150 or more absorbent mats, most of which overlap at least one other absorbent mat of the system.
The absorbent floor system is preferably deployed on a floor or section of a floor of at least about 100 square feet, although it may be deployed to cover an area of less than 100 square feet. In certain embodiments, the total area covered by the absorbent floor system is between about 100 square feet to more than 5000 square feet (e.g., about 100 square feet, about 250 square feet, about 500 square feet, about 750 square feet, about 1000 square feet, about 1250 square feet, about 1500 square feet, about 1750 square feet, about 2000 square feet, about 2500 square feet, about 3000 square feet, about 3500 square feet, about 4000 square feet, about 4500 square feet, about 5000 square feet, more than 5000 square feet). In another embodiment, the absorbent floor system covers about 10,000 square feet or more. In yet another embodiment, the absorbent floor system covers at least 20,000 square feet.
In one embodiment, as illustrated in
In certain preferred embodiments, site evaluation and planning includes identifying areas of high usage, e.g., where there is the potential for a large amount of oil, grease, coolant, and/or other fluids to be present. Identification of such areas may aid in selection of quantities, materials, and types of absorbent mats for use in such areas.
Site evaluation and planning may also include identification of areas in which the floor of the manufacturing facility slopes (e.g., near a drain, down a ramp, etc.). As described below, additional absorbent mats may be employed in such areas to minimize the slope of the walking surface and, accordingly, the need for such mats may be identified during site evaluation and planning. Based on the information gathered during site evaluation and planning, the quantity, types, materials, and sizes of absorbent mats and optional liners to be employed in an absorbent floor system for such site may be determined 808.
For example, based on the available sizes of standard absorbent mats, areas for which such standard absorbent mats are suitable may be identified and the required number and sizes of such standard absorbent mats may be calculated (e.g., for a particular site, based on site evaluation and planning, two standard absorbent mats having dimensions of 3 feet by 10 feet and two standard absorbent mats having dimensions of 2 feet by 3 feet may be selected for an absorbent floor system for such site).
By way of further example, sizes of and suitable materials for pre-site custom cut absorbent mats can be identified based on information gathered during site evaluation and planning, and one or more of such mats may be cut at a location other than the installation site. By cutting some mats prior to arriving at the installation site, installation time may be reduced and any downtime of the manufacturing facility where the absorbent floor system is to be installed may be reduced.
Site evaluation and planning 800 may include counting the number of objects present on the manufacturing facility floor in the area where the absorbent floor system is to be installed 810. Such objects may include work tables, machinery, railings, posts, and other structures. Based on the number and type of objects identified during site evaluation and planning, the quantity, sizes and materials for leaner absorbent mats of an absorbent floor system employed at such site may be determined. In some embodiments, site evaluation and planning may also include estimating the number of cuts required for leaner absorbent mats of the absorbent floor system.
As noted, based on information gathered during site evaluation and planning, materials suitable for the various absorbent mats of an absorbent floor system for such site can be identified. In one example embodiment, absorbent mats with relatively higher weights and/or relatively higher proportions of polypropylene are selected for high waste and high traffic areas and absorbent mats with relatively lower weights and/or relatively smaller proportions of polypropylene are selected for low waste or low traffic areas. In another embodiment, the same weight and composition is selected for all absorbent mats of the absorbent floor system.
In certain embodiments of the present invention, it is contemplated that the top most absorbent mats of the absorbent floor system are placed in the location of a most traveled walkway. Accordingly, site evaluation and planning may include identifying one or more most traveled walkways. In some embodiments, site evaluation and planning includes identifying potential tripping points and calculating the number and length of absorbent mats to reduce or avoid overlaps and/or seams at or near tripping points.
Thus after the site evaluation and planning has been completed, and the number of standard absorbent mats, leaner absorbent mats, pre-site custom cut absorbent mats, pre-site custom cut walkway absorbent mats, and/or most traveled walkway absorbent mats, number of layers, mat weight, etc. have been calculated or determined, the absorbent floor system can be installed. In other embodiments, such as reinstallation of an absorbent floor system, some or all of the components of site evaluation and planning described above are not performed prior to an installation.
In one example embodiment, the floor is degreased by mopping an EF-80 Degreaser produced by Waste Controllers of St. Louis, Mo. on the floor. According to this example embodiment, after the floor is degreased, the floor is manually dried in the location where the single sided hook fasteners will be adhered to the floor (i.e., the mat-hook-floor line). That is, the line along which the single sided hook fasteners will be adhered to the floor is manually dried. In this embodiment, the step of manually drying is completed using low lint micro-fiber wipes. Using the low lint micro-fiber wipes aids in minimizing the number of particles remaining on the floor where the single sided hook fasteners will be adhered (which could adversely impact the integrity of the adhesive on the single sided hook fastener). Accordingly, thoroughly cleaning the floor increases the adhesion between the floor and the single sided hook fastener, reducing or eliminating the need for additional means of retaining the absorbent mats such as tapes, glues, etc. Additionally, cleaning, degreasing and drying the floor aids in extending the life of the adhesion of the single sided hook fasteners to the floor. This also aids in increasing durability of the absorbent floor system because the single sided hook fasteners may be less likely to detach from the floor and, therefore, the absorbent mats may be less likely to slip or be otherwise displaced.
After the floor is cleaned, degreased and dried, a liner is placed on the floor if desired at step 105. This step is optional, as not all installations will utilize a liner. Then mats selected for the absorbent floor system are placed down on the floor at steps 106 through 120. For example, at step 106, standard absorbent mats are placed down on the floor. If any on site cuts in absorbent mats are required at step 108, then leaner absorbent mats are placed down on the floor at step 110. If any pre-site custom cut absorbent mats are required at step 112, then pre-site custom cut absorbent mats are placed down on the floor at step 114. Continuing now to
Although, in general, absorbent mats of an absorbent floor system may be initially placed on the floor in any order, in preferred embodiments of absorbent floor systems, a most traveled walkway absorbent mat lies at least partially on top of the absorbent mats adjacent to the most traveled walkway mat. Placing the most traveled walkway absorbent mats on top of one or more previously placed absorbent mats in the absorbent floor system aids in reducing tripping hazards and permits easier removal and replacement of the most traveled walkway mats if needed.
More generally, mats are preferably installed (and, therefore, ultimately placed) such that an inner-most mat lies directly on the floor and, moving away from such inner-most mat, additional mats lay, in part, on top of an adjacent mat and, in part, on the floor.
For example, as illustrated in
Other placement variations can be used in other embodiments that maintain, at least generally, the preferred inner to outer layering. For example, in another embodiment, absorbent mat 16a could be placed directly on the floor and mats 14b, 14c, and 14d could be placed partially on top of absorbent mat 16a. In yet another embodiment, absorbent mats 14a and 14b could be placed directly on the floor, and absorbent mats 14c, 14d, and 12 could be placed partially on top of absorbent mat 14a.
During installation lower level mats are preferably placed at sufficient distance within the mat-hook-floor line, as described more fully elsewhere herein. By keeping the edges of the lower level mats within the mat-hook-floor line, the outer most lying mats can lie substantially flat allowing for better securing to the single sided hook fasteners and a smoother edge may be created thus reducing or eliminating potential tripping points. In a preferred embodiment, no portion of the lower level mats extends beyond the mat-hook-floor line.
Referring again to
In some embodiments, in order to enhance the absorbent floor system, to further reduce or eliminate potential tripping points, and to ensure that the single sided hook fasteners are cut to the proper length, the slack may be removed from the absorbent mats at step 123 through an optional process called slacking. During slacking, a first short side of an absorbent mat is secured to one or more single sided hook fasteners. Then, the second short side of the absorbent mat is pulled until the absorbent mat is taught, e.g., reducing the likelihood of ridges in the absorbent mat post-installation. The second short side of the absorbent mat is then secured to one or more single sided hook fasteners. After the two short sides of the absorbent mat have been secured along their short sides, one or more single sided hook fasteners may be cut to the desired length and then attached to the floor under the portion of the absorbent mat that lies directly on the floor. The absorbent mat can be secured to the single sided hook fasteners, as described more fully elsewhere herein.
Slacking can be particularly useful in installing absorbent mats over 6 feet in length, however slacking can be performed on any length of absorbent mat. Additionally, on-site custom cuts can aid in holding the mat in place. By performing slacking of leaner absorbent mats prior to cutting, the cuts are more likely to be in the correct location, thereby minimizing the necessity of additional cuts or unintended tripping hazards from misplaced cuts. After the outer most mats are secured to the floor using single sided hook fasteners, at optional step 124 one or more or all of the overlapping mats are secured to or interlocked with one another using one or more double sided hook fasteners (for example, double sided hook fasteners 24a-24aa in
In certain embodiments, the layered absorbent mats may be secured to or interlocked with each other using double sided hook fasteners, while in other embodiments the layered absorbent mats may not be secured to or interlocked with each other using double sided hook fasteners. By not interlocking the layered mats in certain embodiments, these mats can be easily swapped out with clean mats prior to a full reinstallation of the entire absorbent floor system. These layered absorbent mats may also be covered or overlapped by any absorbent mat as described elsewhere herein such as pre-site custom cut absorbent mats, pre-site custom cut walkway absorbent mats, most traveled walkway absorbent mats, etc.
Finally, at step 126 once one or more or all mats have been secured to one another using double sided hook fasteners, any and all leaner absorbent mats are custom cut on-site (for example, cuts 230a and 230c in
More specifically, in certain embodiments, during installation, absorbent mats are leaned against the objects present on the manufacturing facility floor and are therefore called “leaners.” To accommodate and aid in the fit of the absorbent floor system around legs, protrusions, etc. of the objects present on the manufacturing facility floor, the leaner absorbent mats in these particular areas are custom cut on-site during installation. Once the custom cuts are made into the leaner absorbent mats, the leaner absorbent mats can then lie substantially flat on the manufacturing facility floor and/or under the objects present on the manufacturing floor. The custom cuts can be a simple line cut or a complex curve. Additionally, a variety of shapes can be cut into the leaner absorbent mats including, but not limited to, triangles, squares, circles, half-circles, ovals, etc. Accordingly any shape can be cut into leaner absorbent mat to accommodate and aid in the fit of the absorbent floor system around legs, protrusions, etc. of the objects present on the manufacturing facility floor (for example, objects 11a and 11b in
In certain embodiments, for example, the custom cut may be from about 2 inches in length to about 12 inches in length (e.g., about 2 inches in length, about 4 inches in length, about 6 inches in length, about 8 inches in length, about 10 inches in length, and/or about 12 inches in length). Custom cutting the leaner absorbent mats on-site not only aids in allowing the leaner absorbent mats to lie substantially flat on the floor but, in combination with slacking, aids in maintaining the desired position of the absorbent floor system. The custom on-site cuts can be made with a wide variety of tools including, but not limited to, shears, razor knives, carpet knives, hot knives, etc. Preferably, the custom on-site cuts may be made with a hot knife typically used to cut foam because it can produce a clean cut with no frayed edges. Custom on-site cuts can also be made using the same tools on any absorbent mat of the absorbent floor system that will aid in the fit and finish of the entire system. Typically a straight edge may be used to make any straight cuts.
If needed or desired, one or more layers of absorbent mat may be placed in the high usage areas. By utilizing multiple layers of absorbent mat, oil, grease, coolant, and/or other fluids can accumulate in the lower absorbent mats while the top mats remain substantially dry or free of oil and/or grease. Additionally, the multiple layers of absorbent mats in high usage areas can permit even absorption throughout the entire absorbent floor system such that the high usage areas and lower usage areas become saturated at substantially the same time. This can reduce cost to the customer because the entire absorbent floor system can be changed out at the same time instead of mat by mat. Alternatively, one or more of the absorbent mats may be removed and replaced without removing or replacing the entire absorbent floor system. The multiple layers of absorbent mats may also provide cushioning for persons walking on the absorbent floor system such that a separate cushion layer is not required.
In certain manufacturing facilities, the floor may be sloped. The slope of the floor can be measured and the number of layers of absorbent mat required to create a substantially level surface in the absorbent floor system can be calculated. By layering the absorbent mats to create a substantially level surface, the propagation of the oil, grease, coolant and/or other fluid across the floor may be slowed and may aid in even absorption of oil, grease, coolant, and/or other fluids throughout the entire absorbent floor mat system. The number of layers of absorbent mat required to achieve a substantially level surface may depend on the slope of the floor and the weight of the absorbent mat being used. Accordingly, fewer layers of absorbent mats may be required for lesser slopes and more layers of absorbent mats may be required for greater slopes. Accordingly, fewer layers of heavier weight absorbent mats may be used or more layers of lighter weight absorbent mats may be used. In one embodiment, for example, a portion of the floor of the manufacturing facility may slope downward 0.5 inches over a 5 foot length from north to south. In this embodiment, two layers of 15 ounce absorbent mat may be placed on the higher, north end of the slope and three layers of 15 ounce absorbent mat may be placed on the lower, south end of the slope. In another embodiment, for example, a portion of the floor of the manufacturing facility may slope downward 0.75 inches over a 5 foot length from north to south. In this embodiment, three layers of 15 ounce absorbent mat may be placed on the higher, north end of the slope and four layers of 15 ounce absorbent mat may be placed on the lower, south end of the slope. In another embodiment, for example, a portion of the floor of the manufacturing facility may slope downward 0.5 inches over a 5 foot length from north to south. In this embodiment, one layer of 24 ounce absorbent mat may be placed on the higher, north end of the slope and two layers of 24 ounce absorbent mat may be placed on the lower, south end of the slope. In yet another embodiment, for example, a portion of the floor of the manufacturing facility may slope downward 0.75 inches over a 5 foot length from north to south. In this embodiment, two layers of 24 ounce absorbent mat may be placed on the higher, north end of the slope and three layers of 24 ounce absorbent mat may be placed on the lower, south end of the slope.
Multiple layers of absorbent mats may be used to reduce or eliminate the flow of oil, grease, coolant and/or other fluids. In an example embodiment, absorbent mats are layered near the edges and/or walkways of the absorbent floor system. Accordingly, in this embodiment, fluids (e.g., resulting from a spill of oil, grease, or coolant) would have to travel through the multiple layers before reaching the edges and/or walkways of the absorbent floor system. Thus, by providing multiple layers of absorbent mats near the edges and/or walkways of the absorbent floor system, fluids may be slowed and/or stopped before reaching an area such as a walkway or a portion of the manufacturing facility floor that is not covered by the absorbent floor system. The multiple layers may therefore serve as a “wall” or “hill” impeding the flow of oil, grease, coolant and/or other fluids.
In an example embodiment, an absorbent floor system is deployed on a manufacturing facility floor that includes an oven. In this example embodiment, three layers of absorbent mats are installed near the oven. Accordingly, a spill of oil, grease, coolant and/or other fluids on the absorbent floor system would be impeded as it flowed toward the oven by the first mat layer, the second mat layer and the third mat layer.
In embodiments of the absorbent floor system in which a layer of absorbent mats is deployed, the absorbent mats may be layered in a step-wise fashion, such that there is a distance from the edge of the first mat layer and the edge of the second mat layer and another edge from the third mat layer, and so on. Alternatively, the layers of absorbent mats may be coextensive such that the edges of all of the absorbent mats are substantially collinear. In certain embodiments, a single absorbent floor system may employ both types of layering.
If any individual absorbent mats in the absorbent floor system become oversaturated with oil, grease, coolant and/or other fluids over time more so than other absorbent mats in the absorbent floor system, those individual mats may be removed and replaced without replacing the entire absorbent floor system. However, in certain embodiments, the absorbent floor system may be designed so that the entire absorbent floor system can be dismantled such that all the absorbent mats are replaced at the same time. In certain embodiments, the absorbent floor system is dismantled by first removing all of the double sided hook fasteners from the overlapping mats. Then the most traveled walkway absorbent mats and pre-site custom cut walkway absorbent mats may be removed, followed by all pre-site custom cut absorbent mats, leaner absorbent mats and then the all standard absorbent mats. This embodiment of the dismantling process whereby layers are removed is essentially the reverse of the installation process. In other embodiments, dismantling the absorbent floor system may start on a first side of the system and work toward a second side of the system wherein all layers are removed as dismantling progresses from the first side to the second side. If a reinstallation of a new absorbent floor system is contemplated, the single sided hook fasteners may be left adhered to the floor so that they can be reused. In other embodiments, the single sided hook fasteners can be replaced for a variety of reasons including, but not limited to, if they are damaged, are no longer adhered to the floor, the absorbent mats will no longer attach to the hook fasteners, etc. The used absorbent mats may then be placed in a variety of containers including, but not limited to, totes, bins, 55 gallon drums, carts, etc. Preferably, at least one 55 gallon drum is supplied with the absorbent floor system into which the used absorbent mats may be placed.
After the absorbent mats of an absorbent floor system have been removed, they can be cleaned and reused in a variety of ways. In one embodiment, for example, an absorbent mat that is 3 feet by 20 feet can be cut down to a standard absorbent mat size including, but not limited to, about 18 inches by about 18 inches, about 18 inches by about 3 feet, about 18 inches by about 6 feet, about 2 feet by about 3 feet, about 3 feet by about 6 feet, etc. feet so that it can be used in another absorbent floor mat system installation. In another embodiment for example, the custom cuts of a leaner absorbent mat can be cut off such and the resulting absorbent mat can be used in another absorbent floor system. The portions of the leaner mats that had the custom cuts, which were then cut off after dismantling the absorbent floor system can, in certain embodiments, be shredded and inserted into absorbent socks. Therefore, none or very little absorbent mat material is wasted. This reduces the amount of absorbent mat material going to landfills and thus provides an additional advantage over the prior art.
