Abstract
The invention relates to an aerated flooring system for use in athletic arenas or gymnasiums. The flooring system includes a top layer that provides a surface for the activities to be conducted on the floor. The system also includes at least one ventilation device. The ventilation device covers an air flow shaft within the flooring system, helping to prevent debris from falling in the air flow shaft, but allowing air to flow through the ventilation device. The ventilation device allows air to ventilate out of the flooring system. A support layer below the top layer provides support to the flooring system. A ventilation layer below the flooring is sized to allow air movement through the layer. The air flow shafts allow air to travel from the ventilation layer to the ventilation device. A base is below the ventilation layer and provides support for the flooring system above. A blowing device is controlled by a computer system that monitors the system using sensors. The blowing device can provide air circulation through the flooring system by creating air flow through the ventilation layer, through the air flow shafts, into the ventilation device, and out the flooring system. The aerated flooring system can also be adapted to existing conventional flooring systems without the need to tear up and remove the old flooring.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to flooring systems and, especially, aerated flooring systems suitable for use in athletic arenas and gymnasiums.




2. Description of the Background




Conventional flooring uses a plurality of layers composed of different types of materials. The materials and the design of the structure support the weight of the floor itself and objects intended to be placed on or supported by the floor. Such flooring is sometimes designed such that a minimal amount of space exists between the various layers and material components to provide increased strength.




A problem with these flooring systems is that they do not provide aeration and are susceptible to undesirable environmental conditions. For example, in a gymnasium or other athletic arena, the flooring system is subjected to high humidity, slab migration and water leaks caused by clogged plumbing, roof leaks or burst pipes in the walls or flooring, all of which can damage the flooring materials as well as the flooring system. Although a small amount of water may seem fairly innocuous, even small amounts of water and water vapor that persists in the floor can lead to rotting and the generation of distasteful odors or aromas. Larger amounts of water and high humidity cause structural and aesthetic damage to the flooring system as well as the surrounding area. Damage to these areas is difficult or impossible to detect, absent actual removal of the floor itself, and can result in unwanted expansion of the floor components (buckling), excessive contraction producing voids, deterioration, drastic shortening of the life of the component materials, and an often unexpected inability of the flooring to sustain any significant weight, resulting in, at best, structural damage and, at worst, personal injury. Structurally damaged areas are nearly always difficult and expensive to replace, often requiring installation of an entirely new flooring system.




Moreover, damp flooring also attracts insects such as termites and other creatures. These creatures often nest in damp areas of the flooring or subflooring, which becomes a long term habitat attracting and resulting in the proliferation of even more creatures.




One attempt to ventilate the subflooring of an athletic flooring system is described in U.S. Pat. No. 5,526,621. This flooring system requires a subflooring with a labyrinth design having spaces between the boards of the subfloor. This design is not adaptable with most conventional flooring systems, but requires complete replacement of an existing floor. Further, the system does not disclose the use of ventilation devices, but rather indicates that air can escape through conventional gaps which exist in the floor. Although the system includes a humidistat to detect higher than desirable humidity buildup, humidity is only detected if it persists at the exact location of the humidistat. There is no way to detect the location of humidity at other sites. Identifying the location of water and increased humidity is further complicated by the labyrinth design of the subflooring.




SUMMARY OF THE INVENTION




The present invention overcomes the problems and disadvantages associated with current flooring systems and provides an aerated flooring system with greater utility and functionality than is conventionally available. These flooring systems are adaptable to work with most existing flooring systems and to convert such existing systems into aerated flooring systems.




One embodiment of the invention is directed to aerated flooring systems comprising a top layer of flooring; a ventilation layer below the top layer, the ventilation layer being at least a size to allow for air to travel; at least one ventilation device; and an air flow shaft that allows air to travel from the ventilation layer to the at least one ventilation device. Preferably, the at least one ventilation device is placed at an end of the air flow shaft to help prevent debris from entering the shaft area. The at least one ventilation device comprises apertures to allow for air transfer.




Another embodiment of the invention is directed to methods for making an aerated flooring system out of an existing flooring system. These methods comprise connecting a blowing device to an existing flooring system which is capable of circulating air through the flooring. An air flow shaft may also be provided, which is capable of ventilating air out of the flooring system. Air is blown through a ventilation layer allows the air to travel completely through the system.




Another embodiment of the invention is directed to methods for making an aerated flooring system. These methods comprise laying a flooring base and a spacers above the base. A top layer can be laid above the spacers, wherein air can flow between the base and the top layer. An air flow shaft is provided above the base wherein air can flow through the air flow shaft. At least one ventilation device is installed above an end of the air flow shaft to help prevent debris from entering the shaft. The ventilation device may also comprise apertures to allow air transfer.




Another embodiment of the invention is directed to particular ventilation device of the flooring system, which is a vented cover flooring base. The vented cove base comprises a ventilation shaft which is at least of a size to allow for air to travel, an air flow aperture which is operable to release air and is directed in a direction to help prevent debris from falling into the air flow aperture, and a vented cove base operable connected to an edge of a floor and a wall.




Other embodiments and advantages of the invention are set forth, in part, in the description which follows and, in part, will be obvious from this description or may be learned from the practice of the invention.

DESCRIPTION OF THE INVENTION




As embodied and broadly described herein, the present invention is directed to flooring systems comprising an aeration system. These flooring systems provide a means for aerating the area between and below the flooring system while maintaining predetermined environmental conditions such as temperature, humidity and moisture levels within the floor and floor area.




Conventional flooring comprises a plurality of layers that structurally support the weight of the floor as well as the weight of objects to be supported by the floor. Typically, the design is such that a minimal amount of space exists between the various layers and material components thereby preventing any significant ventilation. Although structurally sound, the lack of aeration creates problems in regions of high humidity and in the event of more severe water damage.




It has been discovered that flooring can be created as a system that retains a structural soundness and ability to support any desired weight while providing floor and subfloor aeration to prevent the harmful build up of water and water vapor. One advantage of this system is that the aerated flooring can be designed to maintain one or more desired environmental conditions such as humidity, temperature, and moisture content throughout and below the flooring system. To assist in controlling these conditions, the system can include one or more blowing devices, humidity sensors, temperature sensors, humidifiers, dehumidifiers, air conditioners, heaters, exhaust fans, lighting, modems, other environmental regulation mechanisms or combinations of such mechanisms. These one or more mechanisms can be connected through a designated control center such as, for example, a computer which may be controlled on-site or distally through the Internet, via modem, or another communications system.




Accordingly, another advantage of the invention is that the system can be automated. An automated system can use a plurality of sensors that accurately and efficiently monitor the environmental conditions of the entire flooring, or desired parts thereof, the surrounding area and/or the building conditions. These environmental conditions include, but are not limited to, temperature, humidity and moisture levels of the flooring. Twenty-four hour monitoring can observe the system in addition to providing alarms to indicate malfunctions or undesirable environmental conditions. Accordingly, the system may include an alarm system. Hardware to monitor the system, such as a control center, can be conveniently located in low profile areas such as, for example, under a gymnasium bleacher or another discrete location. Blowing devices, used to stabilize the humidity moisture and temperature, can be protected by secured housing and can use conventional blower parts, such as blades and air filters. Further, the automated system can be operated manually.




Another advantage of the aerated flooring system is that the system can be easily added to an existing floor. This allows users to adapt their current flooring system into an aerated system rather than replacing their entire existing flooring system which represents a substantial economic savings.




Another advantage of the aerated flooring system is that the subflooring is less susceptible to termites and other insects. By controlling the environmental conditions of the flooring system, insects are less likely to infest and damage the flooring. The system is also adaptable to sprayer devices to dispense insecticides, odor combatants, germicides, air freshening scents or any other chemicals determined necessary, above and/or below the flooring system.




Another advantage of the aerated flooring system is that the system can utilize most and likely all conventional materials presently used and commercially available in floors and flooring systems. The quality of the floor and the resiliency of the flooring system is unaffected. Thus, flooring systems can be aerated without a decrease in structural support.




One embodiment of the invention is directed to an aerated flooring system as depicted in

FIG. 1

(the break in the middle of this figure as well as other figures indicates that the flooring system can be any desirable length). The aerated flooring system can be any desirable size and shape, but would typically be designed empirically on a room-by-room basis by one of ordinary skill in the art. There are no mechanical or structural restrictions which require specialized structures or types of materials. Accordingly, the flooring system can be used in any athletic arena, gymnasium, dance floor, aerobic floor, cotton mill, or any room, and the system can be in any residential, recreational, commercial or industrial building. Further, as a significant advantage of the invention is cost savings, aerated flooring systems of the invention are perfectly suited for non-profit institutions such as public schools and other institutions where finances are limited.




The aerated flooring system of the invention comprises a plurality of layers of supporting materials (FIG.


1


). The supporting materials include, for example, a top layer of flooring


80


made of a flooring material such as wood, one or more ventilation devices


20


above top layer


80


such that the ventilation devices


20


help to prevent debris from entering into air flow shaft


40


and into the flooring system, a support layer


50


to withstand the rigors of expansion, contraction and depressions from the activities above the flooring system, a ventilation layer


60


to ventilate the flooring system


10


, a flooring base


70


to support the weight of the flooring and the activities that occur above the flooring system, and a blowing device


82


which operates with an automated system


84


to regulate environmental conditions.




Top layer


80


can be made of any size or thickness that provides appropriate support for the intended use. Appropriate sizes can be determined by one of ordinary skill in the art based on the intended use and the component materials to be used. Top layer


80


has a top surface


30


that provides a surface for the activities to be conducted on the floor. Ventilation devices


20


can be attached to wall


12


and sit on top surface


30


so as not to stop proper expansion and/or contraction. Top layer


80


is preferably made of any conventional flooring material including, for example, rubber, stone or wood such as maple, pine, fir, redwood and oak, or synthetic material such as vinyl, linoleum, plastic, synthetic rubber or plaster, or a combination of one or more such materials. Top layer


80


can also be composed of a rubberized, elasticized or plastic material, for example, as used in wrestling arenas, but may be made of nearly any man-made or synthetic flooring material. Top layer


80


is connected to support layer


50


by adhesive, snaps, screws, hooks, staples, nails, clips or other conventional connecting means.




Ventilation device


20


is used to facilitate air removal from flooring system


10


and helps to prevent debris from falling into flooring system


10


. Ventilation devices


20


can be placed at the edges of flooring system


10


or anywhere else within flooring system


10


such that ventilation device


20


facilitates air flow out of flooring system


10


and helps to prevent debris from falling into flooring system


10


. An example of a suitable ventilation device


20


is depicted in FIG.


2


A.

FIG. 2A

depicts a side view of ventilation device


20


according to one embodiment of the present invention. Ventilation device


20


depicted is a vented cove flooring base. Ventilation device


20


can be connected to additional ventilation devices


20


and Lo a support surface, such as wall


12


. Ventilation device


20


can be in a substantially light angle shape, as depicted. Ventilation devices


20


can be placed all around top layer


80


such that the entire room could be surrounded with ventilation devices. Ventilation devices


20


could also be around any obstruction, such as pillars or columns in the middle of the room. Ventilation devices


20


can be connected to walls


12


or obstructions by adhesive, snaps, screws, hooks, nails, staples or other conventional connecting means. Alternatively, ventilation devices


20


can be placed where necessary for proper air flow without having to be around the entire room. Alternatively still, ventilation devices


20


can be placed a predetermined distance from walls


12


, for example, near the middle of the floor.





FIG. 2B

depicts a rear view of two connected ventilation devices


20


and


21


. Ventilation devices


20


and


21


depicted are vented cove flooring bases. In this depiction, ventilation device


20


is connected to ventilation device


21


by butting the devices together and connecting them with adhesive, snaps, screws, hooks, staples, nails, or other conventional connecting means. Alteratively, ventilation devices


20


and


21


can be butted together tightly without being connected in any other way. Alternatively still, ventilation device


20


can be connected to ventilation device


21


by including a tab on ventilation device


20


and inserting the tab into a notch on ventilation device


21


. At corners, curved or right-angled ventilation devices could be used, or two ventilation devices could simply be connected together at an angle using any of the above mentioned connecting means.




Referring again to

FIG. 2A

, ventilation devices


20


can include one or more air flow apertures


24


and/or


26


. Apertures


24


and


26


can be directed in any desired direction that helps prevent debris from falling into apertures


24


and


26


. As depicted in

FIGS. 2A and 2B

, aperture


24


is on the upper part of ventilation device


20


and is directed downward, while aperture


26


is at the bottom of ventilation device


20


and is directed across top surface


30


of top layer


80


, making it extremely difficult for dirt and other debris to enter apertures


24


and


26


. Ventilation devices


20


also include at least one ventilation shaft


22


on its bottom and/or backside. Apertures


24


and


26


allow air to be released from ventilation devices


20


. As shown in

FIG. 2B

, each ventilation device


20


could easily have three or more ventilation shafts


22


on its bottom and sides. However, ventilation devices


20


could have any number of ventilation shafts


22


. Further, ventilation device


20


could have any number of apertures


24


and


26


. Ventilation shafts


22


and apertures


24


and


26


permit air to exit from beneath, and/or in, and/or around the flooring system.




Referring again to

FIG. 1

, ventilation devices


20


cover air flow shaft


40


at the end


41


of air flow shaft


40


, allowing air to travel through ventilation device


20


and helping to prevent debris from entering into air flow shaft


40


. Air flow shaft


40


allows air to circulate into and out of flooring system


10


. Although air flow shaft


40


is depicted as being next to wall


12


, air flow shaft


40


can be placed nearly anywhere within the flooring system such as, for example, as shown in FIG.


2


E. Air blown in the flooring system can flow through air flow shaft


40


and out through ventilation devices


20


.




Ventilation devices


20


are preferably comprised of a hard rubber, wood, plastic or another natural or man-made product suitable for use in gymnasiums or athletic arenas. Such materials provide resilience and strength, but offer a safer surface to the user. Ventilation devices


20


can rest on top surface


30


of top layer


80


, as seen in FIG.


2


A. Ventilation devices


20


can be connected to a wall


12


and/or the top surface


30


of top layer


80


by adhesive, snaps, hooks, staples, nails, or other conventional connecting means. Alternatively, ventilation devices


20


can be built into top layer


80


so that it is produced as one piece, similar to that depicted in FIG.


2


E.




In addition to facilitating air release, ventilation devices


20


also cover air flow shafts


40


at ends


41


of air flow shafts


40


. By covering ends


41


of air flow shaft


40


, ventilation devices


20


help prevent debris and other material from accidentally falling through into air flow shaft


40


, but still allow air to flow through ventilation devices


20


. Debris such as junk, loose change, dirt, and other objects are prevented from falling into ends


41


of air flow shaft


40


by ventilation devices


20


. Accordingly, ventilation devices


20


can be any device that facilitates air release and helps to prevent debris or other material from falling into the openings in the top layer of the floor.




As depicted in

FIG. 2C

, an alternative ventilation device


20




a


is covering material


21


. For example, covering material


21


may comprise a thin material that covers ends


41


of air flow shaft


40


, such as a plastic material or other suitable material. The distance between covering material


21


and top layer


80


provides a ventilation shaft


22




a


and the end of covering material


21


provides an aperture


26




a.






As depicted in

FIG. 2D

, another alternative ventilation device


20




b


is covering device


23


. Covering device


23


may be part of wall


12


. Covering device


23


covers ends


41


of air flow shaft


40


. The distance between covering device


23


and ends


41


of air flow shaft


40


provides a ventilation shaft


22




b


and the end of covering device


23


provides an aperture


26




b


. This alleviates the need for separate ventilation devices


20


. Additionally, aperture


26




b


may be, for example, an inch or less in size. However, it may be desirable that aperture


26




b


be small enough to prevent most debris from being pushed into air flow shaft


40


, yet still large enough to allow air to flow through ventilation device


20




b.






As depicted in

FIG. 2E

, another alternative ventilation device


20




c


could be a board


27


with small openings


29


. Small openings


29


provide small apertures in ventilation device


20




c


. Board


27


could be placed anywhere in top layer


80


and could be perpendicular or parallel to boards that make up top layer


80


. Air flow shaft


40


could be formed anywhere within the flooring system, as depicted. Additionally, ventilation layer


60


could be directly below top layer


80


and also below support layer


50


, allowing board


27


to be placed in any convenient location. Ventilation device


20




c


allows air to flow through and out its small openings


29


, and also prevents most debris from falling into ends


41


of air floor shaft


40


. Alternatively, small openings


29


could be bore directly into top layer


80


, such that ventilation device


20




c


would comprise small openings


29


in top layer


80


. Small openings


29


would be apertures that let air flow out of flooring system


10


. Alternatively, all of top layer


80


could have ventilation device


20




c


built directly into top layer


80


by having all of top layer


80


have small openings


29


that allow air to flow out of flooring system


10


.




Ventilation device


20




c


is useful when a large amount of area is desired for air flow passage such as underneath bleachers in a gymnasium. Ventilation device


20




c


with small openings


29


is structurally sound, so ventilation devices


20




c


could be used throughout all of top layer


80


. An example of ventilation device


20




c


includes a plurality of boards


27


joined together, each board


27


having multiple ¼ inch small openings


29


placed ½ inch apart.




Alternatively still, ventilation device


20


may be a mesh covering for end


41


of air flow shaft


40


. The mesh covering may be a netting, a screen, or other similar covering that has a plurality of holes or apertures, to allow for air transfer and flow, yet covers end


41


to help prevent debris from falling into end


41


. Any type of mesh or netting could thus be used as ventilation device


20


. The mesh covering could be used as ventilation device


20


regardless of the location of end


41


of air flow shaft


40


.




Alternatively still, ventilation device


20


may be a porous fabric, such as a carpet, rug, mat, foam, or other porous fabric. The porous fabric could allow for air transfer and flow through ventilation device


20


, yet covers end


41


of air flow shaft


40


to help prevent debris from falling into end


41


. Any type of porous fabric that allowed air to flow through it could thus be used as ventilation device


20


. The porous fabric could be used as ventilation device


20


regardless of the location of end


41


of air flow shaft


40


. This would allow the system to be used under a carpeted flooring, such as a carpeted basement, residential room, or office. Further, if, for example, ventilation device


20


was a carpet, when air was ventilated out through the carpet, it would also dry out the carpet if it was damp or wet.




Alternatively still, ventilation device


20


does not have to be placed above the top surface


30


of top layer


80


. For example, if the flooring system were on a second floor, the system could ventilate out the bottom of flooring system


10


and through the ceiling of the first floor. In such an instance, the ventilation device would be below the flooring system. Alternatively still, ventilation device


20


could be outside of flooring system


10


, such that air flow shaft


40


allows air to travel some distance away, with ventilation device


20


above end


41


of air flow shaft


40


and allowing the air to expel outside the system. For example, ventilation device


20


could be at end


41


of air flow shaft


40


some predetermined distance from top layer


80


and the building. Any of the ventilation devices


20


described herein, or any combination of these, can be used anywhere ventilation devices


20


are desired.




Referring again to

FIG. 1

, support layer


50


may comprise any material deemed appropriate to withstand the rigors of expansion, contraction and depressions from above or laterally. Support material


50


may be, for example, comprised of CDX plywood, fir or maple, and of a size and thickness deemed appropriate for the intended use. Support layer


50


does not have to be parallel to top layer


80


. For example, it could alternatively be layered at a 45° angle to top layer


80


, or perpendicular to top layer


80


. Support layer


50


could also be made of boards of plywood. No spaces are needed between the boards in support layer


50


, but such spaces might be used to assist in construction and prevent rubbing between the boards.




Support layer


50


could be placed a short distance from walls


12


or vertical obstructions, for example, a distance of about two inches. This distances creates an air flow shaft


40


between support layer


50


and walls


12


or vertical obstructions. Air flow shaft


40


can be comprised of one shaft adjacent to walls


12


around the entire perimeter of top layer


80


or broken into multiple air flow shafts


40


such as, for example, one around the perimeter of top layer


80


and others around vertical obstructions. Alternatively, air flow shaft


40


can be in any location throughout the flooring system


10


, i.e., air flow shafts


40


do not have to be adjacent to walls


12


. For example, air flow shaft


40


can be a predetermined distance from walls


12


, for example, near the middle of the floor.




Air flow shafts


40


can be two inches wide or any other appropriate distance for the particular flooring being used. The width of air flow shaft


40


can be any size that the elements of flooring permit. For example, the width of air flow shaft


40


is generally in the range of from a fraction of an inch to 5 inches or larger, but is preferably in the range of ½ to 3 inches, and more preferably is 2 inches.




Air flow shafts


40


allow air to travel through ventilation layer


60


and into ventilation devices


20


. While air travels through ventilation layer


60


and through air flow shafts


40


, environmental conditions such as temperature and humidity can be regulated such as, for example, by increasing or decreasing air movement. Further, the air flow helps to remove moisture in the system created by slab migration, water leaks or other problems, and accelerates the drying out process.




Ventilation layer


60


comprises air channels


42


divided by spacers


62


. Spacers


62


can be any size or resiliency deemed necessary for the desired use. For example, spacers


62


may be made of solid spacers, foam spacers, wood, rubber or another conventional material. Spacers


62


can also be pads that are placed on the underside of support layer


50


for protection of support layer


50


in addition to defining ventilation layer


60


. Alternatively, spacers


62


may be long boards spaced apart so as to provide air channels


42


. Spacers


62


can allow for at least some resiliency or cushion in flooring system


10


. Spacers


62


may also be at any angle with respect to support layer


50


, or fill the entire ventilation layer


60


, if necessary. Spacers


62


could also be in a zig-zagged pattern as depicted in FIG.


1


. Alternatively, spacers


62


can be an entire sheet of foam which is either zig-zagged, crisscrossed or prepared in another pattern, or contain air channels


42


within the foam. Spacers


62


support the above support layer


50


and any other layers that may be above.




Ventilation layer


60


may be about ¼ inch thick or, alternatively, any size deemed appropriate to allow for air movement. Ventilation layer


60


should be of a size to permit sufficient air to ventilate through the layer. As the width and length of spacers


62


are increased, the size of air channel


42


is decreased. Alternatively, as the thickness of spacers


62


is increased, the air space between flooring base


70


and support layer


50


is increased. Alternatively, ventilation layer


60


could be directly below top layer


80


such as is shown in FIG.


2


E.





FIG. 3

depicts a drawing of a plan view of the underside of support layer


50


of an aerated flooring system. As depicted, spacers


62


may be placed intermittently throughout ventilation layer


60


. By having smaller individual spacers


62


, a larger air channel


42


is created.





FIG. 4

depicts a drawing of a side view of an aerated flooring system. This view is similar to

FIG. 1

except that clip


90


connects spacers


62


via groove


53


to top layer


80


. Groove


53


is cut into top layer


80


and provides a ledge for clip


90


to connect. Groove


53


may, alternatively, be a tongue that extends outward from top layer


80


for clip


90


to connect. Clip


90


can be made of any material such as, for example, metal or hard plastic, and of any size appropriate for ventilation layer


60


and flooring system


10


to hold spacers


62


in place. A clip channel


92


runs across the flooring system. Clip channel


92


is used to hold the multiple clips


90


in place. Clip channel


92


can be made of any material of any strength, size or shape that can hold clip


90


in place such as metal or plastic. Clip


90


connects to base


70


with an anchor


94


. Anchor


94


can alternatively go through spacer


62


. Anchor


94


can be a metal or wood nail, or any material of any size and strength necessary to hold spacer


62


in place. Clip


90


is especially useful for zig-zagged spacers


62


, as depicted in

FIGS. 1 and 4

. Thus, clip


90


helps keep top layer


80


and spacer


62


together, being affixed to base


70


. Alternatively, support layer


50


can also be used, as depicted. In such an instance, clip


90


helps keep top layer


80


, support layer


50


, and spacer


62


together, being affixed to base


70


. Alternatively still, channel


92


can have a support material, such as a wood strip, running through channel


92


, allowing top layer


80


to be nailed directly to the support material without using clip


90


.




Vapor barrier


72


can be placed above base


70


, and preferably between ventilation layer


60


and base


70


. Vapor barrier


72


is a barrier that prevents moisture from getting through to base


70


or up from base


70


. Vapor barrier


72


is preferably composed of a materials such as, for example, Visqueen. Alternatively, vapor barrier


72


could be a small 6 millimeter thick layer of plastic or polyethylene. Alternatively still, any material that helps to prevent moisture from seeping through to base


70


could be used. Alternatively, vapor barrier


72


could be any water-proof, insulating fiber-glass sheet, such as Mondo EVERLAY. Mondo EVERLAY has multiple vinyl foam nubs which create air pockets. These air pockets can be used to create a ventilation layer


60


between vapor barrier


72


and base


70


. Alternatively, vapor barrier


72


could also help facilitate attachment of other layers to vapor barrier


72


. Base


70


comprises any matter deemed sturdy enough to hold up the activities that are performed on top of flooring system


10


. For example, base


70


could be concrete or another rigid material that is capable of supporting flooring system


10


.




The multiple materials and layers can be kept together with any suitable material, such as adhesive, staples, screws, tacks, nails, snaps, hooks or other conventional connecting means. Alternatively, all the layers could be held together with devices similar to clip


90


.




Blowing device


82


causes air to flow through flooring system


10


by either blowing or sucking air out of flooring system


10


. Blowing device


82


can be any device capable of causing an air turbulence in a flooring system such as, for example, a fan, a blower, a device to force air, any other type of air movement device or any combination of such devices. Blowing device


82


comprises an air movement device


86


, such as fan blades, and a motor. Blowing device can be housed in housing


87


.




Blowing device


82


can also be connected to automated system


84


to monitor the flooring system. Automated system


84


could also be housed in housing


87


and may be locked by lock


85


. A convenient location for blowing device


82


could be under a bleacher, in a closet or outside of the room or area of the flooring. Ambient air can be sucked in or blown out from vents


89


. Blowing device


82


can be anywhere that it has access to ambient air to cause air flow. Further, blowing device


82


can be located in any location where a conventional fan or blowing unit could be located. Additionally, blowing device


82


can connect into ventilation layer


60


at any convenient location through air flow shaft


40


or through a discharge hole


83


, as depicted in FIG.


8


.




As depicted in

FIG. 8

, blowing device


82


and housing


87


can be above top layer


80


. Additionally, discharge hole


83


can be within air flow shaft


40


, and air flow shaft


40


can also extend above top layer


80


. Housing device


87


can be connected to top layer


80


by any connecting means, such as nails. Any number of blowing devices


82


can be used. Using multiple blowing devices


82


allows the system to adjust environmental conditions in only the areas that require adjusting. Further, the flooring system could use a humidifier or dehumidifier in connection with blowing device


82


or, alternatively, a blowing device


82


having a humidifier or dehumidifier.




Automated system


84


can comprise one or more computers linked to one or more humidistats to detect humidity levels. Computers can be functionally connected to operate blower devices to respond, as desired, to changes in humidity levels. Blowing device


82


can therefor be automated, providing twenty-four hour monitoring, on the hour readings, temperature readings above and below the flooring, manual override and codes to only allow access to only certain users (security controls). Such security controls are known to those of ordinary skill and commercially available. Additionally, blowing device


82


could be filtered with conventional filters. Connection tube


88


allows blowing device


82


to be some distance from ventilation layer


60


. If blowing device


82


is some distance from ventilation layer


60


, automated system


84


might be placed in a closer location for ease of monitoring.




Automated system


84


can regulate the blowing device and the environmental conditions in the room, and below and throughout the system, directly above the floor and in the entire building. Automated system


84


can accurately and efficiently monitor temperature, humidity, moisture and other environmental conditions, using computers and monitoring devices such as sensors. Twenty-four hour monitoring can observe the system in addition to providing alarms to indicate malfunctions or undesirable environmental conditions. The alarm, which may respond to sensors that detect a variety of different or the same environmental conditions, may be only audible, only visible, or a combination of visible and audible alarms and, if desired, connected to local emergency offices such as fire or police, or to appropriate personnel. Further, alarms could contact appropriate service personnel via a beeper, Internet connection or automated telephone call. However, automated system


84


can be overridden and be operated using manual commands, i.e., inputting a specific desired temperature or humidity level, can also be entered by appropriate personnel. Thus, the system can either be controlled automatically or manually.




Additionally the system can be regulated to adjust according to the location of the system, as different parts of the country have different humidity and temperature constants. Moreover, automated system


84


can accommodate seasonal changes and/or unusual weather conditions. Based on historical data and data gathered from automated system


84


, automated system


84


can be set up and programed to correctly control environmental conditions.




Automated system


84


can be controlled off-site. For example, one central location can control multiple automated systems for multiple flooring systems located anywhere in the world. A user at the central location could receive data from individual sensors


95


or data on the entire flooring system. The user can also control the blowing device


82


or any other devices flooring system uses. Information can be relayed to the central location via modem, Internet communication link, telephone or another communication means.




In addition, automated system


84


could control spraying devices to dispense insecticides, odor combatants, germicides, air freshening scents or any other chemicals to eliminate insects, odors or other unwanted conditions. When an undesirable condition is detected or the appropriate personal manually gives a command to automated system


84


, the spraying devices are activated. The spray could be introduced near blowing device


82


, thus allowing the spray to disperse through the system. For example, if an air freshening scent were sprayed, blowing device


82


could disperse the air freshening scent through the system and out through ventilation devices


20


. Thus, users above flooring system


10


could smell these freshening scents.




Referring to

FIG. 1

, sensors


95


could be placed anywhere above and/or below the floor, or any other convenient location. For example, sensors


95


could be placed within ventilation layer


60


, within air flow shaft


40


, or any other desired location. Sensors


95


can be placed, for example, every twenty-five feet. Accordingly, sensors


95


can be placed in any location that is appropriate for the particular flooring system.




Sensors


95


relay information back to automated system


84


that regulates environmental conditions. Sensors


95


allow the system to centralize problem areas caused by any undesired environmental conditions. The more sensors


95


used, the more precise the location of any problem is known. Sensors can be any device that is capable of detecting environmental conditions, for example a humidistat, temperature gauge, or moisture probe. Sensors


95


are connected to automated system


84


via electrical wiring to a power source such as a battery or a central electrical supply.




Sensors


95


allow the system to adjust for different conditions. For example, the system can monitor air about to be blown into the flooring system to prevent humid air from being blown into flooring system.




Automated system


84


can run periodic tests to determine the conditions of the flooring system. These tests can occur between preset intervals or randomly chosen. During tests, automated system


84


can obtain data from sensors


95


and adjust the temperature, humidity, and moisture level within the flooring system to a predetermined, desired condition. Alternatively, automated system


84


could continuously read data from sensors


95


and adjust the environmental conditions when necessary.




In addition to blowing device


82


, automated system


84


can use various devices to maintain desired environmental conditions. These devices can include, but are not limited to: humidifiers, dehumidifiers, air conditioners, heaters, exhaust fans, lighting, modems, other environmental regulation mechanisms and combinations thereof. These other devices can be connected to blowing device


82


, be in housing


87


, or be in different locations throughout the building.




Besides keeping the moisture in flooring system


10


regulated, the air flow from blowing device


82


helps keep support layer


50


and top layer


80


dry by percolating dry air up through and across support layer


50


and top layer


80


, through pores in the two layers. Thus, the environmental conditions below and within the flooring system are regulated.




In another embodiment of the present invention, a different ventilation layer


160


can be used as depicted in FIG.


5


. Ventilation layer


160


is similar to ventilation layer


60


and includes spacers


162


and air channels


142


. Spacers


162


have air holes


167


that allow for air flow. Accordingly spacers


162


can be individual pads, intermittent strips or extend throughout the entire ventilation layer such as, for example, with a large foam spacer


162


. Ventilation layer


160


can be used in connection with any other embodiment described herein.




In another embodiment of the present invention, a flooring system


310


with multiple ventilation layers


360


,


361


, and


363


and multiple support layers


350


,


352


,


354


, and


356


can be used as depicted in FIG.


6


. Top layer


380


, base


370


, ventilation devices


320


, connector


388


, blower


382


and sensors


395


are all similar to their corresponding parts in flooring system


10


. In this embodiment, multiple ventilation layers


360


,


361


and


363


exist to help further facilitate air flow. While various spacers


362


,


364


and


366


are depicted, ventilation layers


360


,


361


and


363


can include any combination of spacers


362


,


364


and


366


or other spacers herein disclosed. Further, although three ventilation layers


360


,


361


and


363


are depicted, flooring system


310


can include any number of ventilation layers. Moreover, ventilation layer


360


could be placed above support layer


350


and below top layer


380


, as depicted.




In ventilation layer


360


, spacers


364


are placed intermittently through ventilation layer


360


creating air channels


342


. Ventilation layer


360


may be similar to ventilation layer


60


depicted in

FIGS. 1 and 3

. Alternatively, spacers


364


may be intermittently placed strips, within ventilation layer


360


, that extend the distance across flooring system


310


and either perpendicular, parallel or at some offset angle to top layer


380


. These strips may be attached to the top or bottom of the layer immediately below or above ventilation layer


360


.




As depicted in

FIG. 1

, various spacers can be used in ventilation layer


361


using, for example, spacers in a zig-zagged pattern


362


which are similar to spacers


62


. In ventilation layer


363


, spacers


366


are used. Spacers


363


provide additional support to support layer


354


.




As also depicted in

FIG. 6

, multiple support layers can be placed intermittently between base


370


and top layer


380


. Additionally, support layers can be on top of one another, such as with support layers


350


and


352


. The multiple support layers


350


,


352


,


354


and


356


may, for example, be ½ inch CDX plywood layers. Support layers


350


,


352


,


354


and


356


are similar to support layer


50


of flooring system


10


. Alternatively, there can be any number of support layers and in any location. For example, support layer


356


can be placed directly above base


370


and below ventilation layer


363


. Spacers


366


can thus also be connected directly to support layer


356


.




The multiple support layers and multiple ventilation layers could be placed in any combination and in any number between top layer


80


and base


70


. The multiple support layers and ventilation layers depicted in

FIG. 6

can be used in connection with any other embodiment described herein.




Some examples of possible combinations of different layers in the flooring system can include a top layer with ventilation devices, a first support layer, a ventilation layer and a base. Alternatively, the system can include (i) a top layer with ventilation devices, a first support layer, a second support layer, a ventilation layer and a base; (ii) a top layer, multiple support layers, a ventilation layer, and a base; (iii) a top layer, a support layer, a ventilation layer connected by a clip or nail to the support layer and a base; (iv) a top layer with ventilation devices, multiple support layers, a ventilation layer and a base; (v) a top floor layer with ventilation devices, a first support layer, a first ventilation layer, a second support layer, a second ventilation layer, and a base; (vi) a top layer with ventilation devices, a first ventilation layer, a first support layer, a second ventilation layer, a second support layer, a third ventilation layer and a base; or (vii) a plurality of ventilation layers and/or support layers.




To create an aerated flooring system, it may often be easiest to adapt an existing flooring system, as depicted in

FIGS. 7A

to


7


D. This is less expensive then removing the old flooring system and constructing the aerated flooring system. To accomplish this, one starts with a existing flooring system


210


as depicted in FIG.


7


A. While most conventional flooring systems can be easily modified, flooring systems that are iron bound or have the top layer directly glued to the base could be more difficult or impossible to modify.




It is preferable that the existing flooring system


210


has some type of ventilation layer


260


. Ventilation layer


260


can be any layer that is capable of allowing air to flow some distance through it. If the existing system does not have a ventilation layer


260


of some sort, a ventilation layer


260


has to be first added to the conventional flooring system. In this example, existing flooring system


210


has a top layer


280


, a support layer


250


, and a ventilation layer


260


with some type of spacers


262


and air channels


242


. Also, flooring system


210


has a base


270


and walls


212


.




To adapt existing flooring system


210


to one of an aerated flooring system, air flow shafts


240


are added to the current flooring system


210


, as depicted in FIG.


7


B. Air flow shafts


240


are added by digging or cutting out a short distance from wall


212


down to at least one ventilation layer


260


. For example, air flow shafts can be dug or cut such that they extend two inches from wall


212


. Air flow shafts


240


are similar to air flow shafts


40


.




A blowing device


282


and sensors


295


are added, as depicted in FIG.


7


C. Blowing device


282


can include blades


286


, a motor and use vents


289


. Blowing device


282


is similar to blowing device


82


and sensors


295


are similar to sensors


95


. Additionally, blowing device


282


can house an automated system


284


. Accordingly, other computing equipment and additional regulating devices, such as humidifiers, can also be added, similar to flooring system


10


. Blowing device


282


can be placed some distance from ventilation layer


260


with a connector similar to connector


88


. A convenient location could be under a bleacher, in a closet or outside, similar to blowing device


82


. Additionally, flooring system


210


can be fitted with any number of blowing devices


282


.




Ventilation devices


220


are placed over air flow shafts


240


at end


241


of air flow shafts


240


as depicted in FIG.


7


D. Ventilation devices


220


are similar to ventilation devices


20


,


20




a


,


20




b


and


20




c


, and include ventilation shafts


222


and air flow apertures


224


and


226


. Like ventilation devices


20


, ventilation devices


220


can be any device that facilitates air release and helps to prevent debris or other material from falling into the openings in the top layer of the floor. Thus, a conventional flooring system can be converted to an aerated flooring system of this invention.




The following examples illustrate embodiments of the invention, but should not be viewed as limiting the scope of the invention.




EXAMPLE




A method of making an aerated flooring system can be accomplished by way of the following example. A concrete base


70


is created by laying a slab of concrete. Concrete base


70


is covered with a vapor barrier


72


, such as 6 millimeter polyethylene. A suitable position for blowing device


82


is determined and, if needed, a closet or other location could be prepared for blowing device


82


. Housing


87


for blowing device is built along with connector


88


. Blowing device


87


is inserted into housing


87


. Support layer


50


can be made of individual boards of plywood. Then, ¼ inch spacer strips


62


are placed on the underside of support layer


50


. Alternatively a foam spacer in a zig-zagged pattern


62


is placed above base


70


to create ventilation layer


60


. An approximately ¼ inch space is left at the ends and sides of the boards of plywood of support layer


50


. A two inch expansion void between support layer


50


and walls and vertical obstructions is also maintained. The ¼ inch spaces are for construction purpose and prevent rubbing between the boards. The two inch expansion voids create air flow shaft


40


. Then, top layer


80


is connected to support layer


50


. Top layer


80


, can be made of wood, and can have ventilation devices


20


placed on the top surface


30


of top layer


80


. Any one of the ventilation devices,


20


,


20




a


,


20




b


, or


20




c


, can be placed above top layer


80


.




In operation, blowing device


82


can regulate environmental conditions, such as temperature moisture, and humidity, above, below, and within flooring system


10


. When required, air can be blown into the system, via blowing device


82


. Air is blown in or out of the system through ventilation layer


60


. This helps regulate temperature, moisture and humidity below the flooring and of support layer


50


directly above it, helping to control the moisture in flooring system


10


. After circulating through ventilation layer


60


, air travels up the edges of support layer


50


, through air flow shafts


40


. Air then travels through ends


41


of air flow shafts


40


and into ventilation devices


20


. In ventilation devices


20


, air travels through ventilation shafts


22


, then out through air flow apertures


24


and


26


.
