Sneeze guard air curtain attachment
View Patent ↗Provided is a sneeze guard attachment for creating an air curtain between display food covered by a sneeze guard and a person. The device includes a panel, a frame affixed to the panel that creates a chamber between the panel and the sneeze guard, and a means for forcing air into the chamber. The chamber includes an open end, which allows the air to be forced out of the chamber in order to create an air curtain. The air curtain separates the display food contained in a food bar/food prep area from the consumer. The device can be retrofitted on any preexisting food shield or sneeze guard, and can be utilized with various types of display food, including food items found in buffets, salad bars, hot food bars, roller grills, made-to-order food operations, catering stands, roller grills, sandwich preparation areas, and the like.
1. A sneeze guard attachment for creating an air curtain between display food covered by a sneeze guard and a person, said attachment comprising:
a panel having an upper surface and a lower surface;
a frame affixed to said panel lower surface and defining a chamber between said lower surface of said panel and said sneeze guard, said chamber having an open end;
a fan adapted to force air into said chamber and out said open end, such that said air forms an air curtain between said display food and said person;
wherein a chamber extends between the lower surface and the sneeze guard to direct the air curtain from an outlet of the fan to an open side of the panel, the open side formed by a distal end of the sneeze guard;
wherein the chamber bounds the air curtain from an exterior environment until the air curtain exits the open side; and wherein the panel and sneeze guard bend to direct the air curtain in a desired direction.
2. The device of claim 1 , wherein said fan comprises a filter configured to purify air prior to entering said chamber.
3. The device of claim 1 , wherein said self-service food bar comprises one or more of a buffet, a salad bar, a hot food bar, a roller grill, a made-to-order food operation, a sampling stand, a catering stand, or a sandwich preparation area.
4. The device of claim 1 , wherein said means for forcing air into said chamber further comprises an off-site means for generating forced air comprising a central fan, blower, or compressor attached to said panel via one or more ducts.
5. The device of claim 4 , wherein said off-site central fan, blower, or compressor is located under the counter of a self-service food bar, above or below a self-service food bar, in a basement, attic, a different room, or outside of the building.
6. The device of claim 4 , wherein air flows from said off-site central fan, blower, or compressor through said one or more ducts to a diffuser, and flows out of said chamber via said open end to create an air curtain between said display food within a self-service food bar and the external environment outside of said self-service food bar.
7. The device of claim 1 , wherein said sneeze guard attachment further comprises one or more advertising indicia display.
8. The device of claim 7 , wherein multiple sneeze guard attachments are installed on said self-service food bar, and a single indicia display attaches over top of multiple diffusers.
9. The device of claim 1 , wherein the chamber is laterally bound by the frame.
10. The device of claim 1 , wherein the sneeze guard and panel have a uniform distance therebetween.
11. The device of claim 1 , wherein the panel corresponds to the shape of the sneeze guard.
12. The device of claim 1 , wherein the chamber extends past the distal end of the sneeze guard.
