The present invention relates to devices, systems, and methods for sanitizing objects; to devices, systems, and methods for sanitizing moving objects; more particularly, to ultraviolet (UV) light sanitizing devices, systems, and methods for use in preventing microbial or pathogen growth on objects related to shopping, including shopping carts or commercial shipping packages/parcels, or transportation carts, such as golf carts.
Many modern economies are supported by consumer buying and commercial selling of goods. While internet based online shopping continues to grow, many consumers shop in the traditional manner by visiting brick and mortar stores to purchase their goods. At many stores, such as grocery stores or big box stores such as WALMART, shopping carts are provided to customers to aid in the shopping experience. While the ability to maintain the cleanliness of shopping carts has always been a source of concern as a mechanism for preventing the spread of disease, the 2019-2020 COVID 19 outbreak has made store owners keenly aware of the need to protect consumers during their shopping outings.
As a visible symbol of the shopping experience, maintaining these business tools in a clean and sanitized manner provides an opportunity to south consumer fears associated with shopping post pandemic times. Moreover, because shopping carts are so widely used and touched by many patrons throughout the day, quick and efficient mechanisms to clean and sanitize each cart are paramount in a strategy to prevent the spread of disease, whether it is COVID 19 related, or other diseases, such as influenza, the common cold, or food borne illnesses. Because of the wide spread use, washing carts with soap and water or other liquid sanitation compositions may not be optimal. As such, devices or systems for sanitization, particularly devices and systems that utilize ultraviolet (UV) light systems that disinfect quickly and safely, are needed.
Embodied in the present invention are devices, systems, and methods for disinfecting equipment. Particularly, the invention is directed towards ultraviolet (UV) light sanitizing devices, systems, and methods for use in preventing microbial or pathogen growth on objects related to shopping, including moving carts, such as shopping carts, commercial shipping packages/parcels, and other non-shopping carts, such as golf carts. An illustrative embodiment of a UV light based disinfection device, preferably a UV light based cart sanitization device, is configured to disinfect multiple units, such as shopping carts. The UV light based cart sanitization device may include a housing, a track or pathway for one or more shopping carts, disinfecting and/or sanitizing source(s), such as UV light source(s), and a control box. The UV light based cart sanitization device may include an internal package/parcel track for exposing packages or parcels to UV light.

To sanitize the shopping carts 108, or packages/parcels, the cart sanitization device 10 uses one or more sanitizing units, illustrated herein as UV light panels 200.
The UV light panel 200 may include a power cord for plugging into an electrical outlet or an electrical outlet bank or be operatively connected or wired, via, for example, use of True One connectors/plugs (manufactured by Neutrik) or other mechanisms known to one of skill in the art, to multiple UV light panels 200 and a central power ON/OFF control unit 18 or button so each of the multiple UV light panels 200 operate simultaneously when powered ON or powered OFF or timed run/operating cycles. The UV light panel 200 is preferably secured to the one or more portions of the cart sanitization device 10 via mechanical fastening members, such as screws and bolts, and may be configured to pivot. Preferably, the UV light panel 200 utilizes one or more LED UV-C bulbs or LEDs (emitting in the range of 200-400 nm, preferably in the range of approximately 254 nM to about 280 nm). As used herein, the term “about” or “approximately” defines any value between greater than zero and 20% above or below a stated value or range. While described as using UV-C light, other UV lights that have the ability to inactivate pathogens (both viruses and bacteria) by impacting the cellular RNA and DNA, damaging nucleic acids, and preventing microorganisms from infecting and reproducing, or acting as a disinfectant may be used as well. The cart sanitization device 10 may be configured so that when powered ON (OFF), all UV light panels 200 turn ON (OFF) and emit light at the same time, or each individual DV light panel 200 may be turned ON (OFF) and emit light separately and independently.
The UV light panels 200 may be arranged within the cart sanitization device 10a to provide UV light exposure to multiple surfaces of the object in need of being exposed to sanitizing light. Accordingly, the UV light panels 200 may be arranged to provide UV light from one or more portions of the top (i.e. top or roof 34), one or more portions from a first side (i.e. first (left) side wall 26), one more portions of a second side wall (i.e. second opposing (right) side wall 28), or combinations thereof. Such arrangement allows for exposing the object, i.e. shopping carts, golf carts, or parcels, or shopping cart track/pathway 14, or internal track or pathway for packages or parcels 20 to UV light along one surface, two surfaces, three surfaces, or more than three surfaces, thus providing at least a 180 degree arch of direct UV light exposure. The UV light panels 200 may be arranged to provide overlapping UV light exposure areas. If UV light panels are provided on the shopping cart track/pathway 14 or on the bottom surface (i.e. the bottom wall 50), objects within the cart sanitization device 10 may be have a 360 degree UV light exposure.
To prevent accidental UV light exposure, the cart sanitization device 10 may include an in-use warning system. The in-use warning system may include an LED beacon in-use warning light 112, see
The control box 18 may include all the hardware necessary to operate and control function, particularly the electrical functioning of the cart sanitization device 10; and may include, for example, wiring for each of the CV light panels 200 or the LED beacon in-use warning light 112, fuses, terminal block, transformers, and the like. The control box 18 may also include a WIFI switch with power cord (not shown), such as a SONOFF WIFI connector, to be used to turn all UV light panels 200 “ON/OFF” via an app.
Alternatively, the UV sanitization device 10 may be RF (radio frequency) compatible and include an RF key fob for quick on/off functioning. The UV sanitization device 10 may be configured to operate using other wireless technologies as well, such as BLUETOOTH. The UV sanitization device 10 may be configured to be a smart device, and include the necessary hardware and/or software. The cart sanitization device 10 may be configured to communicate with an electronic device, such as a smart phone or computer tablet, i.e. IPAD. Control of the UV light functioning, i.e. on/off, scheduling of on/off times, run times, and when each of the individual UV light panels 200 turns on/off may also be accomplished using a cell phone or other remote electronic device.
The cart sanitization device 10 may include one or more occupancy sensor(s) 111, see
