Abstract
An apparatus and method for minimizing the amount of smoke to which a shielded person is exposed. The apparatus, or air rail, has a conduit and a fan. The conduit has an air outlet through which air is forced by the fan. In operation, the fan generates an air flow that enters the conduit and exits through the air outlet. The exited air flow is directed generally away from the shielded person and is interposed between the shielded person and the smoke. The exited air flow therefore creates a barrier which minimizes the amount of smoke to which the shielded person is exposed. By minimizing the amount of smoke to which the shielded person is exposed, the apparatus and method creates a better environment for the shielded person.
Description




BACKGROUND




In the gaming industry, second hand smoke is an ongoing problem for dealers, pit bosses, employees, and customers alike. Second hand smoke creates unpleasant working conditions and is a health hazard. It has been known for over a decade that second hand smoke is nearly as likely to cause lung cancer as direct smoke itself. Casinos, however, want their customers to enjoy themselves. More specifically, casinos encourage their patrons to enjoy things like gambling, drinking, and smoking. Indeed, outside of some smokey pubs, bars, taverns, and saloon's, casinos are the last refuge for the smoker.




Unfortunately for the casino dealer, the heavy smoking of the clientele does not make life easier, more enjoyable, or healthier. When dealing at a casino gaming table, such as a blackjack table, the dealer is often confronted with a table full of smokers. The smokers often do not care what direction their exhaled smoke goes in, or worse, they directly aim it towards the dealer. Furthermore, the circulation in casinos often causes the smoke to be blown towards the dealer no matter where the smokers aim it.




Outside of the casino environment, there are many similar situations of unwanted smoke, air, odors, or vapors. In the aforementioned bars, taverns, pubs, and saloons there are many bartenders who do not want to be exposed to second hand smoke. In shops and labs, many people deal with chemicals and other material that produce unwanted vapors. Likewise, there are many similar situations with unwanted odors.




What is needed is an apparatus that inhibits and/or hampers the amount of smoke, vapors, and odors a person is exposed to.




What is needed is an apparatus that checks, constrains, or reduces the amount of smoke, vapors, and odors a person is exposed to.




What is needed is an apparatus that limits, restricts, and/or minimizes the amount of smoke, vapors, and odors a person is exposed to.




What is needed is an apparatus that protects and/or shields a person from smoke, vapors, and odors.




SUMMARY OF THE INVENTION




The invention is generally an apparatus that reduces, minimizes, or eliminates the amount of smoke vapor or odor that a person at a table is exposed to. More specifically, the invention creates a barrier of air interposed between the protected person and the air borne nuisance. Preferably, the barrier of air is created using an air rail.




Generally, the air rail comprises a fan, a conduit, and an air outlet. The fan moves air or creates an air flow, a substantial portion of which moves through the air conduit and exits out the air outlet. The exited air is interposed between the person and the smoke. The interposed air creates a barrier of air in front of the person at the table which reduces or prevents the smoke reaching the person. The air rail is generally mounted on the side or edge of the table closest to the person being shielded or protected from the smoke or other airborne nuisance.




It is an object of this invention to create an apparatus that inhibits and/or hampers the amount of smoke, vapors, and odors a person is exposed to.

DETAILED DESCRIPTION




The invention relates to an apparatus that eliminates, hampers, inhibits, checks, constrains, refrains, restricts, limits, reduces, or minimizes exposure to second-hand smoke or other air-bourne contaminants. More particularly, it relates to an air rail for use on a table that is not only simple to use, but is also reliable, durable, and easy to manufacture. The air rail shields a person at a table by creating a positive air flow up and away from the shielded person. If, for example, there are other people smoking at the table, the shielded person is shielded from the smoke. This positive air flow is generally at a 90 degree or smaller angle away from the top of the table or surface that the air rail is mounted on. For ease of description the air rail examples are described as being used to block smoke, however, the embodiments may be used for any airborne nuisances or contaminants. Likewise, the shielded person may be a dealer, agent, vendor, bartender, pit boss, pit runner, pit manager, waiter, waitress, machinist, cook, or any one else exposed to smoke, contaminants, or other airborne nuisances.




A preferred embodiment of the air rail


30


is shown in FIG.


1


. The air rail


30


comprises a fan


32


and a conduit


34


. The fan


32


intakes air, moves air and/or creates an air flow. Generally, the CFM of the fan


32


ranges from 8 CFM to 60 CFM. Preferably, the fan


32


has a CFM of 24. The fan


32


ordinarily comprises an air intake


36


, a fan outlet (not shown), blades (not shown), a motor (not shown), and an on/off switch


38


. The air intake


36


is an opening that allows the fan


32


to intake air. As shown in

FIG. 1

, the fan


32


may have fan vents


40


that regulate the amount of air that is taken in and that prevent fingers and clothing from touching the fan blades. The air intake


36


is generally aligned in the same manner as the fan


32


itself. In

FIG. 1

, the fan


32


and the air intake


36


are aligned vertically, but, the air intake


36


may also be positioned horizontally or at any other angle.




The fan outlet is an opening that allows the moved air or air flow to exit the fan and enter the conduit


34


. The fan


32


and the conduit


34


are generally connected at the fan outlet of the fan


32


. The fan outlet can connect to the conduit in a variety of ways. For example, the fan outlet can have a male end (not shown) which slides inside a female end (not shown) on the conduit


34


, or vice-versa. Alternatively, the fan outlet can be molded or glued to the conduit


34


during the manufacturing of the conduit


34


. Other means of connecting the fan


32


to the conduit are discussed below.




The blades are located within the fan


32


, and when the blades turn, they intake the air through the intake


36


and move the air and/or create the air flow. The blades are generally aligned perpendicular to the direction of the air flow through the conduit, although the blades may be aligned parallel to this air flow.




The motor is located within the fan


32


, and when on, the motor turns the blades, to cause the blades to move the air and/or create the air flow. The motor may turn the blades directly or indirectly, through a belt or similar means. The motor generally has one speed, although it may have multiple speeds, thus providing for adjustability. The motor is preferably a DC motor, in which case the fan


32


also has a AC/DC converter


42


. A DC motor is safer in an environment where drinks are often spilled. The fan


32


may also have a quick-disconnect


44


which may be used to cut off power to the fan


32


to prevent electrocution or any other mishap. Likewise, the fan


32


may have a fuse, a circuit breaker, an automatic or safety shut-off, and/or manual shut-off for protecting the fan and the person from short-circuits, voltage spikes, electrocution or any other problem associated with an electrical device. The on/off switch


38


may be located at any conveniently accessible position on the fan


32


. The fan


32


may also have a filter (not shown) which filters the air and keeps the fan clean. It is noted that a commercially available, off-the-shelf fan may be used.




The conduit


34


is preferably connected to the fan


32


, as shown in

FIG. 1

, so that a substantial portion of the air moved or air flow created by the fan


32


enters and travels through the conduit


34


. The conduit


34


is placed on the end or side of the table (not shown) where the person (not shown) being shielded is standing or sitting. The conduit


34


may be connected to the top, edge, or side of the table at the end or side where the air rail is placed. The preferred length of the conduit


34


depends on the length of the end or side of the table where it is placed. The conduit should be approximately as long as the table end or side. For a typical casino gaming table, the conduit length would be approximately four feet. The height of the conduit


34


can range between approximately 1 inch and 6 inches, but, is preferably approximately 3 inches. As illustrated by these dimensions and the Figures, the conduit


34


is generally rectangular in shape, although the top surface with may be rounded. In alternative embodiments, the conduit


34


may be cylindrical, triangular, pyramidal, or a variety of other shapes. Furthermore, the width of the conduit may range between ¼ inch to 3 inches, but, is preferably approximately 1 inch. The conduit may be made of a variety of materials, including, plastics, plexiglass, wood, poly-carbon, aluminum (similar to aluminum air ducts), composite material, metal, natural, or man-made materials.




Referring to

FIG. 1

, the conduit


34


has an air outlet


46


that allows the air to exit the conduit


34


. Generally, the air outlet


46


is located on the top surface of the conduit


34


and comprises a plurality of holes or vents, as shown in FIG.


1


. The size of the air outlet


46


is variable, but, it can range from holes or vents with a diameter of approximately one sixteenth ({fraction (1/16)}) of an inch to two inches to a hole or vent as long as conduit and a sixteenth ({fraction (1/16)}) of an inch wide to 2 inches wide. The holes or vents are preferably circular, although they may be rectangular, square, or a variety of different shapes. Generally, spacing of the holes or vents varies from a quarter (¼) inch to a foot or greater. In the preferred embodiment, the holes or vents are circular with a one-quarter inch (¼″) diameter, spaced two inches apart, and are positioned at a 60° angle above the plane of the table and 30° from a line through the center of the top of the conduit. One method of creating the holes or vents is to drill through the top of the conduit with a one-quarter inch (¼″) drill bit at the desired angle.




A substantial portion of the air that travels through the conduit


34


exits through the air outlet


46


. This exited air


48


is interposed between the shielded person and the smoke (not shown) to create a barrier


50


between the shielded person and the smoke and/or restrict the amount of smoke that reaches the shielded person. The number of the holes or vents, the location of the holes or vents, and the size of the holes or vents affect the size and shape of this barrier


50


. The exited air


48


is interposed in a generally vertical direction or at an angle slanting away from the shielded person. Preferably, the interposed air rolls away from the shielded person and towards the smoke at the top or peak of its trajectory.




The air rail


30


may create the barrier


50


or minimize the amount of smoke that the shielded person is exposed to by creating various eddies


52


in the air flow, as shown in

FIGS. 2



a


and


2




b


. The eddies


52


are created when the exiting air


48


rolls over in a circular motion and is blown back upwards again or when the exiting air


48


causes neighboring air to roll, as seen in

FIGS. 2



a


and


2




b


. The eddies


52


may be created by varying the air flow, the shape of the air outlet


46


, the relative positioning of the air outlet


46


, or in any other manner normally used to create eddies


52


. For example, if two adjacent outlets are positioned so that the air flows exiting from each crosses, eddies


52


may be created. The eddies


52


should roll away from the shielded person to keep the smoke away from the shielded person. The eddies may break-up the smoke, block the smoke, and/or diffuse the smoke.




Referring to

FIGS. 2



a


and


2




b


, the eddies


52


may be created at a variety of heights above the air outlet


46


. For example, the eddies


52


may created anywhere from directly above the air outlet


46


to thirty-six inches above the air outlet


46


or higher. The eddies


52


may have a variety of diameters, ranging from one-eighth (⅛ inch) to eight (8) inches or larger. Likewise, there may be any number of eddies


52


, from one eddy to hundreds of eddies


52


.




The air rail


30


may also create a barrier


50


that varies in size and strength along the length of the conduit


34


.

FIG. 3

shows an embodiment of the air rail


30


where the air outlet


46


is configured so that the exited air


48


is fanned out at varying heights along the length of the conduit


34


. This creates a barrier


50


that is stronger or more impenetrable in certain predetermined areas. The advantage of this is that the air rail


30


may be adjusted to compensate for more smoke on one side, area, or portion of the table or coming from one direction. Likewise, the varied exited air


48


could help adjust for the ambient or existing airflow in the room. The varied exited air


48


may be achieved with adjustable holes or vents, where the size of the hole or vent may be increased or decreased, for example, by tightening a screw, a knob, or sliding a cover over the hole or vent. Likewise, the varied exited air


48


may also be achieved by increasing the number of fans


32


and varying the location of the fans


32


.




The air rail


30


may also be designed, as seen in

FIG. 4

, so that the air outlet


46


is a plurality of separate groupings


54


or holes or vents. With the two groupings


54


shown in

FIG. 4

, the air outlet


46


creates two separate barriers


50


to smoke. Similar to the embodiment seen in

FIG. 3

, this is particularly effective when the smoke is flowing in particular areas, portions, or sides of the table. The groupings


54


may be located in the position found most effective to create a barrier


50


and prevent smoke from reaching the shielded person.




As noted above and shown in

FIG. 4

, the fan


32


may be positioned horizontally. With the fan


32


positioned as such, the intake


36


will generally also be aligned horizontally. The intake


36


may be located on the top of the fan


32


, as depicted in

FIG. 4

, or on the bottom of the fan


32


.




The vents or holes that comprise the air outlet


46


do not have to be stationary, but, may be moveable and adjustable. Accordingly,

FIGS. 5



a


and


5




b


depict an embodiment of the air rail


30


in which the air outlet


46


is or includes adjustable vents


56


. The adjustable air vents can be a variety of shapes and sizes. For example, they may the size and shape of a adjustable vent found in an automobile dashboard. Likewise, they may be the size and shape of adjustable vents in airplanes or trains. The adjustable vents


56


may be adjusted to change the direction of the exited air


48


. The adjustable vents


56


may change the exited air


48


direction vertically, horizontally, rotatably, up and down, and side to side, as seen in

FIG. 5



a


. The adjustable vents


56


may be, for example, on rollers, pivots, hinges, ball bearings, threads, or slides. To change the direction of the exited air


48


vertically and horizontally, for example, the adjustable vent


56


would be pivoted upwards or downwards, as shown in FIG.


5




b


. Likewise, if the adjustable vents


56


were on ball bearings, or were otherwise rotatable, the vents


56


could be turned circularly to change the direction of air flow. Such rotatable vents


56


would allow the changing of the direction of the exited air flow from forward and away from the shielded person to backwards and towards the shielded person, towards the left, or towards the right, as shown in

FIG. 5



c


. Given the often unpredictable environmental conditions in a casino, this adjustability could prove useful.




As shown in

FIG. 5



a


, the adjustable vents


56


are on tracks that let them slide along the length of the conduit


34


. Wheels, ball bearing or other means that let them slide could be substituted. The adjustable vents


56


, therefore, allow for the creation of a variety of air outlet


46


configurations. The air vents may be grouped together to create a large barrier


50


or they may be grouped separately to create a plurality of barriers


50


. The adjustable vents


56


give the shielded person more control over the barrier


50


and allow the shielded person to compensate for different environmental conditions.





FIGS. 6



a


and


6




b


shows the air outlet portion of an air rail


30


with another variety of adjustable vent


56


. In this embodiment, the adjustable vent


56


has a plurality of openings


58


, a vent cover


60


, and a rib


62


. The openings


58


may be completely open, in which case the exited air


48


will produce a wide barrier


50


. The rib


62


moves the vent cover


60


. The shielded person, therefore, could move the rib


62


to move the vent cover


60


and reduce the size of the openings


58


. The shielded person therefore, can use the ribs


62


to adjust the air outlet


46


to increase or decrease the exited airflow


48


. Alternatively, the adjustable vent


56


may also be constructed to be rotatable within the conduit


34


, thereby allowing the barrier


50


to be created at different angles. For example, when the vent cover


60


is 90% closed, the opening is aimed at a small height above the table of surface the air rail was mounted on. However, if the adjustable vent


56


were rotated counter-clockwise, the opening would be aimed at a greater height.




The conduit


34


does not have to be a set shape or length. Rather, as

FIG. 7

shows, the air rail


30


may have a flexible conduit


34


. This flexible conduit


34


is comprised of flex line


66


and may be made of a variety of flexible or malleable materials, including rubber, plastic, composite, man-made or natural material. The flexible conduit


34


typically has approximately the same size range as described above for the conduit


34


. The flex line


66


is positioned along an existing rail or trim on one side of a table. Preferably, the flex line


66


may be secured to the existing rail with a lip (not shown) or other connecting means. For example, an existing table railing, molding, or padding (not shown) could be removed, the flex line


66


placed on the edge of the table, and the railing remounted so that it applies a pressure on the lip and holds the flex line


66


in place. As shown in

FIG. 7

, the flexible conduit


34


may be comprised of a plurality of flex lines


66


. A plurality of flex lines


66


allow for greater ease in use and installation, as well as a greater variety of configurations. The flex lines


66


are connected to each other and to the fan


32


with a connector


68


, which securely holds them together.





FIGS. 8



a


,


8




b


, and


8




c


show a section of the air rail


30


in greater detail than the

FIGS. 1 through 7

. As seen in

FIG. 8



a


, the present embodiment of the air rail


30


comprises a fan


32


, an conduit


34


, and a transition piece


70


. The fan


32


is similar to the fan


32


described above, with reference to

FIGS. 1 and 4

, and is positioned horizontally with the intake


36


(not shown) located on the bottom of the fan


32


.




The conduit


34


is also constructed similarly to the conduit


34


described above, with reference to

FIGS. 1

to


7


. Referring again to

FIG. 8



a


, the conduit


34


also has an air chamber


72


and track guide


74


. The air chamber


72


is filled with the moved air or air flow created by the fan


32


. The track guide


74


is located in the air chamber, a the bottom of the conduit


34


and is comprised of two opposing tracks. The track guide


74


allows the transition piece


70


to connect with the conduit


34


, as is described below.




The transition piece


70


connects the fan


32


to the conduit


34


and allows the fan


32


to be placed at different positions along the conduit's


34


length. Although the transition piece can be a variety of sizes, the transition piece


70


is preferably approximately four to eight inches long, two to four inches tall, and one-half to one inch thick. Generally, the transition piece


70


will be approximately the same width as the conduit. The transition piece


70


, as shown in

FIGS. 8



a


,


8




b


, and


8




c


, includes an air chamber intake


76


, an air chamber output (not shown), a DC adapter plug


78


, mounting screw holes


80


, an on/off switch


38


, and glide tracks


82


. The air chamber intake


76


is an opening that allows the moved air or air flow created by the fan


32


to enter the transition piece


70


, through the fan outlet, and pass through the air chamber output and into the conduit's


34


air chamber


72


. The fan


32


is mounted so that the fan outlet aligns with the air chamber intake


76


with a gasket


84


and mounting screws


86


(seen in

FIG. 8



a


) that pass through the mounting screw holes


80


. The gasket


84


is secured to the fan


32


and has holes (not shown) for the screws


86


to pass through. When the screws


86


are tightened through the gasket


84


, the fan


32


is secured to the transition piece


70


. The on/off switch


38


turns the power, DC or AC, on and off. The DC adaptor plug


78


simply allows power from a DC adaptor to pass through a cord (not shown) and to the fan


32


.




The glide tracks


82


are indentations that run the length of the transition piece


70


. The transition piece


70


connects to the conduit


34


by sliding the glide tracks


82


over the track guides


74


of the conduit


34


. Connected as such, the transition piece


70


is slid along the track guides


74


to any position along the length of the conduit


34


. Therefore, the fan


32


can be placed at any position along the length of the conduit


34


. Likewise, additional transition pieces


70


and fans


32


can be added to the air rail. The variable positioning of the fan


32


or fans


32


provides greater flexibility in the installation and use of the air rail


30


.




One example of an air rail


30


construction and installation is as follows. Generally, the conduit


34


is built to a length appropriate for the table the air rail


30


is being installed on. Typically, for a standard


4


foot casino gaming table, the length of the conduit


34


would be approximately four feet. The fan


32


is then mounted on the transition piece


70


, using a screw


86


and gasket


84


as described above with reference to

FIG. 8



a


. Next, the transition piece


70


is connected to the conduit


34


with the glide track


82


as described above with reference to

FIG. 8



a


. The transition piece


70


and fan


32


are slid along the conduit


34


until the best position is found. A filler (not shown) is placed in the bottom of the conduit


34


to provide an air-tight seal of the opening on the bottom of the conduit


34


not covered by the transition piece


70


. The filler is typically made of the same material as the conduit


34


or transition piece


70


, and is designed to fit in the bottom of the conduit


34


, resting on the track guides


74


. Both ends of the conduit


34


are sealed, and the air rail


30


is ready to be installed.




The air rail


30


is installed by connecting the conduit


34


to the table. For example, in one embodiment the conduit


34


has screw or bolt holes and is screwed or bolted to the table through the screw or bolt holes. Alternatively, an adhesive could be used to connect the conduit


34


to the table.





FIGS. 9



a


,


9




b


, and


9




c


show an alternative embodiment of the air rail


30


that also allows the fan


32


to be placed, mounted, and/or installed anywhere along the length of the conduit


34


. In

FIG. 9



a


, the transition piece


70


is an elbow


88


with an air chamber intake


76


a left outlet


8


and a right outlet


90


. The air chamber intake


76


is connected to the fan


32


by sliding the intake


76


into an opening (not shown) in the fan


32


. The air chamber intake


76


allows the moved air or air flow created by the fan


32


to enter the air chamber


72


of the conduit


34


. When the fan is located at one end of the conduit


34


, the end of the conduit


34


is placed in either the left outlet


89


or right outlet


90


of the elbow


88


and a cap


92


is placed on the other outlet, as shown in

FIG. 9



b


. If the fan


32


is located somewhere, such as the middle of the conduit


34


, other than the end of the conduit


34


, the conduit


34


is cut into two pieces at the point where the fan


32


is to be located. The opposing ends of the conduit


34


pieces are placed in the left outlet


89


and right outlet


90


of the elbow


88


, as shown in

FIG. 9



c


. The conduit


34


fits tightly into the outlets and is thus held in by pressure. However, the conduit


34


may be held in place by glue or screws. The glue would be placed on the ends of the conduit


34


being placed into the outlets, while the screws would be screwed through transition piece


70


and into the conduit


34


.




The air rail


30


has been described above as being used with a table, and is generally envisioned being used on a gaming table and blocking smoke. In most casinos, the gaming tables will be used in a room with a floor and a ceiling. However, gaming tables may be used in open air casinos without ceilings. Furthermore, it is noted, however, that the air rail


30


may be used in any locale where air borne nuisances are a problem for the shielded person. For example, the air rail


30


may be used on a bar so that it shields bartenders from the smoke of bar patrons. The air rail


30


may be whatever length is necessary to be used on a bar or any other place. Ideally, to create a sufficient barrier, there should be more than one fan. A fan


32


for every six feet of the conduit


34


operates well. However, with better conditions or fan power, the distance between fans may be increased.




The terms and descriptions used here are set forth by way of illustration only and are not meant as limitations. Those skilled in the art will recognize that numerous variations are possible within the spirit and scope of the invention as defined in the following claims.
