For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used as a cashier station attachment for creating an air curtain between a customer and a retailer. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

Definition

[0026] An “air curtain” is an invisible and continuously blown curtain of air that creates a barrier or shield. The air curtain diverts airborne hazards, including insects, contaminants, particles, pathogens, and respiratory droplets away from a location. Air curtains are recommended by the FDA as an effective means of protection from airborne hazards, as enumerated in Food Code 6-202.15(D)(2). As described herein, air shields prevent insects, contaminants, pathogens, and the like that are expelled from the mouth or nose of a person from being spread from one person to another.

[0027] The terms “cashier”, “retailer”, “customer”, “individual”, and “person” are used interchangeably throughout this description to denote that the air curtain created by the present invention is design to prevent the transmission of insects, contaminants, pathogens, and the like that are expelled from the mouth or nose of a person from being spread from a person on one side of the air curtain to a person on the other side of the air curtain. The terms should not be considered limiting in any way.

[0028] Referring now to FIG. 1, there is shown a perspective view of the cashier station shield 11. The device includes a substantially planar body 12 comprising an internal chamber 13, an open side comprising a diffuser 14, an attachment means for attaching the device to a cashier station, preferably a pair of hooks 15 (which will be shown in greater detail below), and a power source. Disposed within the internal chamber 13 is a means for forcing air into the internal chamber 13 and out the diffuser 14, which creates an air curtain. The diffuser 14 can additionally include adjustable louvres 17 that change the airflow angle. In the preferred embodiment, the means for forcing air into the internal chamber 13 comprises a fan. The air curtain creates an invisible barrier between a first person and a second person, such as a retailer or cashier and a customer. The device prevents the spread of contaminants, pathogens, and the like that are expelled from the mouth or nose of a person on one side of the air curtain from contacting a person on the other side.

[0029] The substantially planar body 12 is configured to enable the cashier station shield 11 to rest flush against a cashier station. As shown, the planar body 12 is substantially trapezoidal in shape, however, any desired shape can be utilized. The top of the planar body 12 includes the diffuser 14, which directs air from inside the internal chamber 13, through the planar body 12, when it is expelled. The internal chamber 13 extends from the planar body 12 and provides a means for drawing air into the device and expelling it through the diffuser 14. The internal chamber 13 preferably includes an indicia cover 16 thereon. Preferably, the indicia cover 16 includes advertising indicia, such as a variety of messages, advertisements, and the like. The indicia cover 16 can be permanent or can include a removable cover that can be installed and removed as desired.

[0030] In all embodiments of the present invention, the indicia cover 16 can be designed with customized indicia to display logos, trademarks, slogans, advertising sales, specials, or other important information that a company wishes to convey to customers. Non-limiting examples include advertisements for particular types of sales during the year, sanitation guidelines, and the like. When designed to be replaceable, the indicia cover 16 can be quickly removed and replaced with updated indicia as desired.

[0031] Air is directed into the cashier station shield 11 to create an air curtain via a means for forcing air into the internal chamber 13. In the preferred embodiment, this is accomplished with a fan disposed within the internal chamber 13. The fan is a conventional fan that is well understood in the art and is adapted for drawing air into the internal chamber 13. In a first embodiment, the fan can be operated by an on-off switch. In a second embodiment, the fan can run on a preprogrammed timer. In a third embodiment, the fan can include a motion sensor system that activates the fan when motion is detected, such as when a customer comes within a predefined distance of the cashier station. In a fourth embodiment, the fan can operate via a remote control. In a fifth embodiment, the fan can operate via a computer or smartphone application.

[0032] The fan can additionally include a means of filtering or purifying the air prior to its entering the internal chamber 13. In one embodiment, the fan includes one or more of an air scrubber filtration system, such as a HEPA filter or an ultraviolet sterilizer. Any known means for filtering and/or purifying the air can be utilized with the fan.

[0033] Referring now to FIG. 2, there is shown a perspective view of the air intake 21 of the internal chamber 13. Air is drawn into the internal chamber 13 of the cashier station shield 11 through the air intake 21 via the fan. The fan preferably functions in a similar manner to a computer fan, wherein rotation of the fan causes air to enter into the internal chamber 13 through the air intake 21. The air passes through a filter or purifier as describe above prior to exiting through the diffuser 14, as best illustrated in FIG. 1. The air intake 21 preferably contains grates 22 to prevent large objects from entering into the internal chamber 13 and damaging the components therein. Also contained within the internal chamber 13 are the necessary components to operate the fan, such as circuit boards, power source components, and the like.

[0034] Referring now to FIG. 3, there is shown a perspective view of the cashier station shield 11 creating an air curtain. The arrows represent air 31 forming an air curtain upon exit from the diffuser 14. Air 31 is directed into the internal chamber 13 through the air intake 21 via the fan, travels into the substantially planar body 12, and flows out of the cashier station shield 11 through the diffuser 14. The air 31 is compressed as it travels from the internal chamber 13 into the substantially planar body 12. Compression occurs because the substantially planar body 12 has a reduced volume as compared to the internal chamber 13. The substantially planar body 12 comprises an empty chamber with a width substantially less than its height and length. The diffuser 14 is positioned along the entire length of the planar body 12. The length of the planar body 12 and diffuser 14 can be constructed in any desired size in order to create an air curtain of a desired size. Sizes ranging from 24-48 inches in length are contemplated, however, any desired size can be used depending on the particular application.

[0035] Referring now to FIG. 4A, there is shown a perspective view of a first embodiment of the cashier station shield attachment means 41. In a first embodiment, the cashier station shield 11 comprises one or more hooks 42 attached to the back side of the substantially planar body 12. In a non-limiting example, the hooks comprise J-hooks 42 attached to the back side of the substantially planar body 12. The hooks 42 are designed to secure the cashier station shield 11 to the side of a cashier station. In one embodiment, the hooks 42 are attached via one or more fasteners 43. As shown, the cashier station shield 11 includes two J-hooks 42 spaced along the back side of the substantially planar body 12 in order to support the cashier station shield 11 when it is attached to a cashier station. The design of the J-hooks 42 enable the cashier station shield 11 to be quickly attached and detached from the cashier station shield 11 as desired. It is contemplated that the exact size, shape, and configuration of the J-hooks 42 can be altered as required to attach the device to cashier stations of differing configurations. In one embodiment, the J-hooks 42 can be removed and replaced with a different fastening means to suit particular needs.

[0036] Referring now to FIG. 4B, there is shown a perspective view of a second embodiment of the cashier station shield attachment means 44. In a second embodiment, the cashier station shield 11 comprises one or more hooks 44 attached to the back side of the substantially planar body 12. In a non-limiting example, the hooks comprise C-hooks 45 attached to the back side of the substantially planar body 12. The hooks 45 are designed to secure the cashier station shield 11 to the side of a cashier station. In one embodiment, the hooks 45 are attached via one or more fasteners 46. As shown, the cashier station shield 11 includes two C-hooks 45 spaced along the back side of the substantially planar body 12 in order to support the cashier station shield 11 when it is attached to a cashier station. The design of the C-hooks 45 enable the cashier station shield 11 to be quickly attached and detached from the cashier station shield 11 as desired. It is contemplated that the exact size, shape, and configuration of the C-hooks 45 can be altered as required to attach the device to cashier stations of differing configurations. In one embodiment, the C-hooks 45 can be removed and replaced with a different fastening means to suit particular needs.

[0037] Referring now to FIG. 5, there is shown a perspective view of the cashier station shield 11 installed on a cashier station 51 and creating an air curtain. As shown, the cashier station shield 11 is attached to a track 52 on the side of the conveyor belt 53 via a pair of hooks 54. The arrows represent air 31 forming an air curtain upon exit from the diffuser 14. Air 31 is directed into the internal chamber 13 through the air intake 21 via the fan and is filtered or purified. The cleaned air 31 is compressed as it travels from the internal chamber 13 into the substantially planar body 12. Air 31 then travels from the internal chamber 13 into the substantially planar body 12 and flows out of the cashier station shield 11 through the diffuser 14. The cashier station shield 11 is preferably positioned between the location where a retailer or cashier stands to operate a cashier machine and where the customer stands when making purchases. The orientation of the diffuser 14 causes the air 31 to travel vertically when expelled therefrom.

[0038] As can be appreciated, the vertical flowing of the air 31 creates an invisible and continuously blown curtain of air that forms a barrier or shield. The air curtain diverts airborne hazards, including insects, contaminants, particles, pathogens, and respiratory droplets that would ordinarily be expelled from the mouth or nose of a retailer or customer at a cashier station. Any airborne hazards expelled, such as a sneeze or cough that travel towards the direction of the air curtain will be trapped in the flowing air, prevented from passing through, and blown up and away from the cashier station. In addition, the cashier station shield 11 permits the exchange of items through the air curtain. As an example, a customer can pass items to a cashier, such as discount cards, coupons, or cash. Conversely, a casher can hand items to the customer, such as purchased items or a sales receipt.

[0039] The cashier station shield 11 can be quickly installed by using the pair of hooks 54 to hang the device on the track 52 adjacent to the conveyor belt 53. The cashier station shield 11 can operate via battery or an electrical plug that connects to a standard power outlet. The device further provides multiple means for operating the cashier station shield 11. Non-limiting examples include operation via an on-off switch, a preprogrammed timer, a motion sensor, a remote control, or via a computer or smartphone application.

[0040] Overall, the present invention provides a new and improved device for creating an air curtain between a customer and a retailer at a cashier station. The device creates an air curtain to prevent the exchange of contaminants, pathogens, and respiratory droplets produced by the customer or retailer from being passed from one person to another. Additionally, the device permits the exchange of goods between customers and retailers without the need for maneuvering around a plexiglass barrier. The device can be retrofitted for use with existing cashier stations, and can be quickly installed and removed as required. This in turn provides a cost effective and simple solution to increase safety for customers and employees.

[0041] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
