Definitions
- the present invention relates to an air diffuser. More specifically, the present invention relates to an improved air diffuser for use in shooting ranges and other environments.
- a diffuser is an air box having an air inlet and a plurality of air outlets, and is designed to release air uniformly from the outlets, such that each outlet releases a similar amount of air as compared to the other air outlets.
- a diffuser which extends across the width of a shooting range and is disposed behind or above the shooters can release air evenly across the width of the shooting range.
- the even flow of the air is important because it prevents eddies or other turbulent current which might inhibit gasses and airborne particles from being carried down range with Suitable air vents can be made downstream in the shooting range so that air flows from behind the shooters and down the shooting range, carrying smoke and particles away from the shooters.
- Shooting range diffusers are typically formed from steel.
- the diffusers are formed with a steel air box which extends across the shooting range and is covered by parallel sheets of steel which have a plurality of small holes formed therein. When air is introduced into an inlet in the air box, the box becomes pressurized inside and air flows out of the holes formed in the sheets of steel to develop consistent airflow.
- These boxes are expensive as they require considerable labor to construct, and as steel is increasingly expensive.
- These air diffusers are also expensive to ship, as many of the parts for the diffuser are 3-dimensional in nature. Additionally, existing air diffusers can be somewhat difficult to clean and maintain, and can be damaged during shipping.
- a diffuser which utilizes a plastic diffuser surface instead of a metal surface.
- a plastic surface is less expensive than a metal surface as plastic is cheaper and easier to form than metal.
- diffusers commonly have curved surfaces and a plastic diffuser front may be formed and shipped flat and bent as it is installed, making the diffuser easier to make and ship.
- a diffuser is provided which is easier to clean and maintain.
- a diffuser according to the present invention may be formed with hinges so as to allow a person to open the diffuser from the top and the bottom.
- the diffuser with plastic surfaces better prevents denting caused by impacts.

Abstract
Description
- The present application claims the benefit of U.S. Provisional Application Ser. No. 60/710,007, filed Aug. 19, 2005, which is incorporated herein in its entirety.
- 1. The Field of the Invention
- The present invention relates to an air diffuser. More specifically, the present invention relates to an improved air diffuser for use in shooting ranges and other environments.
- 2. State of the Art
- In shooting ranges and other areas where bullets are fired, it is desirable to control the movement of air. Specifically, it is desirable to create movement which draws smoke and air-born particles away from the shooter and, typically, down range.
- In order to promote a uniform flow of air across all of the shooters and down the shooting range, diffusers have been utilized. A diffuser is an air box having an air inlet and a plurality of air outlets, and is designed to release air uniformly from the outlets, such that each outlet releases a similar amount of air as compared to the other air outlets. Thus, a diffuser which extends across the width of a shooting range and is disposed behind or above the shooters can release air evenly across the width of the shooting range. The even flow of the air is important because it prevents eddies or other turbulent current which might inhibit gasses and airborne particles from being carried down range with Suitable air vents can be made downstream in the shooting range so that air flows from behind the shooters and down the shooting range, carrying smoke and particles away from the shooters.
- Shooting range diffusers are typically formed from steel. The diffusers are formed with a steel air box which extends across the shooting range and is covered by parallel sheets of steel which have a plurality of small holes formed therein. When air is introduced into an inlet in the air box, the box becomes pressurized inside and air flows out of the holes formed in the sheets of steel to develop consistent airflow. These boxes are expensive as they require considerable labor to construct, and as steel is increasingly expensive. These air diffusers are also expensive to ship, as many of the parts for the diffuser are 3-dimensional in nature. Additionally, existing air diffusers can be somewhat difficult to clean and maintain, and can be damaged during shipping.
- There is thus a need for an range air diffuser which is less expensive to produce and transport, and which is easier to maintain.
- It is an object of the present invention to provide an air diffuser for shooting ranges and other environments which is less expensive and more convenient to use than existing diffusers.
- According to one aspect of the present invention, a diffuser is provided which utilizes a plastic diffuser surface instead of a metal surface. A plastic surface is less expensive than a metal surface as plastic is cheaper and easier to form than metal. Additionally, diffusers commonly have curved surfaces and a plastic diffuser front may be formed and shipped flat and bent as it is installed, making the diffuser easier to make and ship.
- According to another aspect of the invention, a diffuser is provided which is easier to clean and maintain. A diffuser according to the present invention may be formed with hinges so as to allow a person to open the diffuser from the top and the bottom.
- According to still another aspect of the present invention, the diffuser with plastic surfaces better prevents denting caused by impacts.
- These and other aspects of the present invention are realized in an air diffuser as shown and described in the following figures and related description.
- Various embodiments of the present invention are shown and described in reference to the numbered drawings wherein:
-
FIG. 1 shows a perspective view of a diffuser according to the present invention; -
FIG. 2 shows a partial view of a diffuser plate of the diffuser ofFIG. 1 and according to the present invention; -
FIG. 3A shows an end view of the diffuser ofFIG. 1 and according to the present invention; -
FIG. 3B shows an alternate end view of the diffuser ofFIG. 1 and according to the present invention; and -
FIG. 4 shows a partial perspective view of a section of the diffuser ofFIGS. 1-3B and according to the present invention. - It will be appreciated that the drawings are illustrative and not limiting of the scope of the invention which is defined by the appended claims. The various embodiments shown accomplish various aspects and objects of the invention.
- The drawings will now be discussed in reference to the numerals provided therein so as to enable one skilled in the art to practice the present invention. The drawings and descriptions are exemplary of various aspects of the invention and are not intended to narrow the scope of the appended claims.
- Turning to
FIG. 1 , a perspective view of a diffuser according to the present invention is shown. Thediffuser 10 is often formed into a semi-cylindrical shape as shown. Thus, semi-circular orarcuate side pieces 14, a back piece (not shown) andfront plate 18 are used to form thediffuser 10. Thefront plate 18 is formed from a sheet of flexible plastic, and may be attached to thesides 14 with a plurality offasteners 22, which may be bolts, screws, rivets, pop rivets, etc., with pop rivets being presently preferred. The flexible plastic is advantageous as a flat sheet may be easily bent around thecurved sides 14 without pre-forming. Typically, air enters through the back or sides of thediffuser 10 and exits through uniform holes in thefront plate 18. The length and overall size of the diffuser may be adjusted to accommodate varying room sizes and air flow requirements. - Turning now to
FIG. 2 , a partial front view of a front plate according to the present invention is shown. The diffuser plate orfront plate 18 is formed from a sheet of plastic as mentioned earlier. Many plastics are suitable. It is desirable that the plastic be flexible so as to easily bend around thesides 14, It is also desirable that the plastic is not brittle, as this will allow for easier machining or forming of the plastic and will inhibit cracking of the plastic during use. Additionally, the plastic should be sufficiently rigid to maintain the desired shape. Suitable plastics include ABS, polyethylene, polypropylene, styrene, polystyrene, acetate, etc. - The
front plate 18 is typically formed withattachment holes 34 whereby the front plate may be attached to the frame of thediffuser 10. Additionally, thefront plate 18 is formed withair holes 38 through which air exits the diff-user 10. Theholes diffuser 10, air is pushed into the diffuser body by a blower or fan. Theair holes 38 are sized such that the air inside of thediffuser 10 is pressurized by the blower or fan and a pressure drop is generated as air moves throughair holes 38. The pressure drop across thefront plate 18, and the corresponding increased pressure inside of thediffuser 10, generates a fairly uniform flow out of theair holes 38, such that a similar amount of air flows out of eachair hole 38. Thus, the number and size ofair holes 38 is adjusted according to the size of thediffuser 10, the amount of air moving through the diffuser, the size of the blower or fan, etc. Additionally,multiple diffuser plates 18 may be used such that the air passes through afirst diffuser plate 18 and asecond diffuser plate 18. - Turning now to
FIG. 3A , a sectional view of a diffuser according to the present invention is shown. Thediffuser 10 is formed with adiffuser box 46,side plate 14,first diffuser plate 18,second diffuser plate 18, and anair inlet 50.Air inlet 50 allows thediffuser 10 to be connected to an air source such as a blower or fan. Thediffuser plates 18 are configured so as to provide uniform air flow out of thediffuser 10. It will be appreciated that, depending on the circumstances in which thediffuser 10 is used, it may be advantageous to use different numbers ofdiffuser plates 18. A single plate may be more efficient in some situations, while two ormore diffuser plates 18 may be advantageous in other situations, as they provide more uniform flow. It may be that diffuser plates may be formed with a single size hole 38 (FIG. 2 ) and hole spacing, and that it is more convenient to use twodiffuser plates 18 than to form diffuser plates with varyingair hole 38 configurations. Thus, a machine such as a punch may be set up to form the diffuser plates and need not be readjusted for different sizes ofdiffusers 10. - The
diffuser 10 may also be formed with atop hinge 54 and abottom hinge 58. While a singletop hinge 54 andsingle bottom hinge 58 are shown in this side view, it will be appreciated that a number or top hinges 54 and bottom hinges 58 may be used along the top and bottom edges of thediffuser 10. The hinges are mounted to the diffuser such that thesides 14 and diff-user plates 18 may be pivoted away from the back 46. The hinges 54, 58 may be arranged such that atop hinge 54 is used with a bottom catch, allowing thesides 14 anddiffuser plates 18 to be released and pivoted upwards for cleaning or maintenance, or such that abottom hinge 58 and top catch is used, allowing thesides 14 anddiffuser plates 18 to be pivoted downwardly. - According to one aspect of the present invention, top and bottom hinges 54, 58 may be used, and formed such that the
hinge pin 62 may be removed from thehinge bottom hinge 58 allows thesides 14 anddiffuser plates 18 to be pivoted upwardly. Releasing thetop hinge 54 allows thesides 14 anddiffuser plates 18 to be pivoted downwardly. Releasing both of thehinges sides 14 anddiffuser plates 18 to be removed completely. The hinges 54, 58 may be plates with holes formed therein, and having a pin or bolt passed through the holes to form a hinge. The hinges 54, 58 may also be formed from tubes with hinge pins placed inside of the tubes. Many types or hinges, including releasable hinges, are suitable. - Turning now to
FIG. 3B , an alternate end view of the diffuser of the present invention is shown. The diffuser is the same as that ofFIG. 3A and is numbered accordingly. As such, the differences will highlighted herein. Theair inlet 50 of thediffuser 10 is mounted to the upper surface of the back 46. Thediffuser 10 also includes one or more baffles 52. Thebaffles 52 aid in directing airflow from theinlet 50 to thediffuser plates 18, and air in providing a more even air flow from the diffuser. Thebaffles 52 may be curved as shown, or may be straight. - Turning now to
FIG. 4 , a partial perspective view of a side and a connecting rail of a diff-user according to the present invention is shown. A connecting rail 70 is attached to theside 14 so as to provide a stronger structure to receive thediffuser plates 18 and to provide mounting surfaces to attach thediffuser plates 18. Theside 14 is shown withbrackets 74 which may easily be formed by bending a tab so as to be perpendicular to theside 14. Thebrackets 74 are shown withholes 78 which correspond withholes 34 ofFIG. 2 and which allow thediffuser plate 18 to be attached to theside plate 14 with bolts, screws, rivets, etc. - The edge of a
diffuser plate 18 may be attached to the connecting rail 70 to further strengthen thediffuser 10 and to seal air leaks. Accordingly, the connecting rail 70 may have a flange 82 configured to receive adiffuser plate 18. The flange 82 may typically be formed withholes 86 whereby thediffuser plate 18 may be attached. Flange 82 provides a location whereby aninner diffuser plate 18 may be attached. Thus, it will be appreciated that the connecting rails 70 and other parts of the diffuser may easily be designed to accommodate varying numbers and sizes ofdiffuser plates 18. - A
channel 90 may also be formed whereby an edge of adiffuser plate 18 may be inserted. Thechannel 90 may be formed between twoflanges 94. Thechannel 90 may be designed such that once a diffuser plate is attached tobrackets 74, no attachment is necessary to secure thediffuser plate 18 into thechannel 90 and to prevent excessive air leakage around the edge of thediffuser plate 18. Alternatively, holes 98 may be formed through theflanges 94 so as to permit fastening of thediffuser plate 18. A simple single flange, such as one offlange 94, may be used in place of a channel. It will be appreciated that internal bracing may be used to strengthen the diffuser, such as corner braces or diagonal braces extending between connecting rail 70 andside 14 as may be necessary for a particular size or design of diffuser. - It will be appreciated that a diffuser according to the present invention may be made in varying sizes according to the needs of a particular use. It will also be appreciated that a diffuser according to the present invention may be significantly less expensive than conventional shooting range diffusers. Conventional difflusers have been made from steel in order to provide a diffuser which is strong enough to withstand the abuse of a shooting range. Steel is expensive, and is more difficult to machine. Thus, available diffusers are somewhat expensive. Applicant has found that plastic diffuser plates are strong enough for a shooting range, and may even be more durable as they do not dent as a metal plate would when accidentally bumped. Applicant has also found that a diffuser with plastic diffusion plates is less expensive to ship, as the diffuser may be shipped unassembled, and all of the pieces are relatively flat. Existing diffusers have a steel diffusion plate which must be bent to the desired shape before shipping and assembly, requiring a larger object be shipped at additional cost. If a replacement diffuser plate is required, a replacement plate may be shipped flat to the customer. The diffuser plates are easily bent into the desired shape as they are installed.
- In all, the cost of the diffuser can be reduced by more that 80 percent while providing comparable performance. Additionally, the diffuser of the present invention can be readily cut down to size in the event measurements were not accurate. With a conventional steel diffuser, a new diffuser would have to be ordered.
- A diffuser according to the present invention is easier to service than existing diffusers. Existing diffusers may be sealed, or may have a piano hinge on the top of the diffuser. Shooting range operators have found existing diffuser designs difficult to clean and maintain. As previously discussed, applicant's design involving top and bottom releasable hinges allows easy access to the diffuser for cleaning and maintenance.
- Applicant has also found that the plastic diffuser plates provide another unique advantage. The diffuser plates can act as an air filter. As most plastics do not conduct electricity or effectively diffuse electrical charge, the constant air flow through the plastic diffuser plates creates an electrostatic charge on the plates. The electrostatic charge on the diffuser plates attracts dust particles from the air. The additional filtration provides an important benefit in a shooting range, where dust particles in the air may commonly include smoke or even metal particles such as from the lead bullets which are not desirable to inhale.
- There is thus disclosed an improved air diffuser. It will be appreciated that numerous changes may be made to the present invention without departing from the scope of the claims.
