Abstract
Disclosed is a mailbox sanitization device employing ultraviolet lamps mounted therein. The lamps are activated after placement of mail, postcards, packages and the like into the mailbox for approximately 60 seconds. The ultraviolet lamp may further produce residual ozone sufficient to destroy most viruses found on the materials placed within the mailbox. The mailbox may be operated in remote areas by use of low voltage or in a commercial setting for protection of postal employees.
Description
- This invention is directed to the field of mailboxes and in particular to mailbox utilizing ultraviolet lamps for localized surface treatment of mail.
- The ability for germs to be transmitted from person to person is well known. Various products, such as sanitization solutions, and techniques, such as frequent hand washing, are known to help prevent the spread of viruses. Typically the transmission of germs from one person to another is by accident.
- For example, in a residential situation a postal delivery person sorts mail by their delivery address where the mail is deposited in a box located at the recipient's residence. It is not unusual for the postal worker to handle thousands of pieces of mail each day, as well as open hundreds of mailboxes, each of which may hold various strands of germs. Further, the postal delivery person may shake the hand of numerous patrons, open building doors and mailboxes, any of which may harbor germs. If the postal worker wears gloves, he may protect himself but not the mail. Thus, a virus may be received as as a neighbor sneezing while depositing his mail and the postal worker and becoming the unsuspecting carrier for the germs.
- As evident by the ease of transporting germs, postal workers also need protection from the public as they are constantly exposed to the germs carried by the mail. Gloves are a known option but typically are not worn due to apparently inconveniences has from heat, lost of dexterity, and allergic reaction that some individuals have to gloves such as those made from latex.
- Of current concern is that a segment of the population does not care to abide by common cleanliness etiquette, or maliciously attempts to spread viruses. The mail has been found to be easy way of transporting spores used to intentionally cause harm to unsuspecting victims. In such instances the unsuspecting handler of mail, as well as the recipient, can be subjected to dangerous viruses.
- Thus, what is lacking in the art is a device that automatically subjects mail to ultraviolet radiation for purposes of destroying germs by use of a conventional style mailbox container.
- Disclosed is a mailbox that is modified to include an ultraviolet light source. Mail placed into the mailbox is subjected to intense ultraviolet light by use of 254 nm lamps for destruction of germs, or 185 nm lamps that are capable of providing producing ultraviolet light and residual ozone.
- In a preferred embodiment mail items, such as postcards, envelopes, brochures, cd's, and so forth) are placed inside a mailbox container housing ultraviolet lamps. When the mailbox door is closed, the ultraviolet lamp is activated for a period of about 60 second. During this process, the mail is subjected to a very high level of ultraviolet light for purposes of killing germs. Depending on the type of germicidal lamp employed, the ultraviolet light may also create an ozone residual to destroy germs that are hidden from the radiation light.
- The mailbox ultraviolet lamps may be operated by a remotely located low voltage electrical source (e.g. 12 volts DC), solar power, or battery power. When the mailbox is mounted to a secure structure, the unit may be operated directly on 120 volts AC.
- Thus an objective of the invention is to teach the use of a mailbox as a microbial/germicidal sanitization container.
- Yet another objective of the invention is to disclose a the use of a residential mailbox for purposes of treating mail before receipt by a mailman or a patron.
- Another objective of the invention is to provide an ultraviolet light mailbox that operates on low voltage.
- Still another objective to the invention is to provide a commercial mailbox receptacle for treatment of mail and protection of postal employees.
- Another objective of the instant invention is to employ ultraviolet lamps that produce ozone.
- Yet still another objective of the instant invention is to provide a viewing port to safely determine operation of the ultraviolet lamps.
- Other objectives and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention. The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.
- FIG. 1 is a perspective view of the ultraviolet light mailbox of the present invention;
- FIG. 2 is a sectional side view of the inside of the ultraviolet light mailbox;
- FIG. 3 is an end view of the ultraviolet light mounted bracket; and
- FIG. 4 is a simplified electrical schematic depicting power routing for the ultraviolet light mailbox.
- Although the invention will be described in terms of a specific embodiment, it will be readily apparent to those skilled in this art that various modifications, rearrangements and substitutions can be made without departing from the spirit of the invention. The scope of the invention is defined by the claims appended hereto.
- Now referring to FIG. 1, set forth is a pictorial of a
mailbox 10 having a conventional shape and further defined as ahousing 12 having aninterior 14 and anopen end 16. Adoor 18 has aninner surface 20 and anouter surface 22. Thedoor 18 is pivotly attached byhinge member 24 to theopen end 16 of thehousing 12. In a conventional format the mailbox may have aflag 26 that can be raised to indicate to a postal worker that items are inside the mailbox for pickup. In this embodiment themailbox 10 is mounted on apost 28. In theinterior 14 of thehousing 12 is a firstultraviolet lamp 30 positioned so as to provide effective distribution of ultraviolet light to the mail. The ultraviolet light recommended is either a 254 nm wave length capable of providing germicidal destruction or a 185 nm capable of producing radiant light and a residual amount of ozone. Thelamp 30 is protected by a galvanizedscreen 32 preferably constructed from 19 gauge wire. Similarly alower lamp 34 is located along thebottom surface 36 of thehousing 12 and also protected by a galvanizedscreen 38. Preferably theinterior 14 of thehousing 12 is coated with galvanized paint due to the reflective properties of galvanized material which enhances operation of the ultraviolet light, but further provides a material of construction which inhibits growth of bacteria. The screen material allows full passage of ultraviolet light but prevents mail insertion from collapsing the screen so as to cause breakage to the lamps. In instances where excessive mail may be placed within the mailbox, mail slots may be used to organize the mail to allow separation and enhanced contact with the ultraviolet light. In instances where packing of porous materials is expected, the use of the ultraviolet light capable of producing a residual amount of ozone is preferred to allow for proper disinfection. It should be noted that common spreading of germs is located on the outside surface of the mail, especially those being last handled. Thus, the interaction of the ultraviolet light from the bottom surface and the top surface of the mailbox with reflecting side surfaces, is deemed sufficient for most installations. Referring now to FIG. 2, shown is theultraviolet lights interior 14 of thehousing 12.Switch mechanism 40 is available for engagingdoor 22 for purposes of operating atimer 42 that allows operation of thelamps transformer 42 may be located at the mailbox. For instance, in commercial applications such as those where the recipient of the mail is the United States Postal Service, the mailbox would be considered a commercial box and the use of a locally mounted ballast may be preferred. However, in residential applications where the mailbox may be located along the outer property edge, where it is acceptable to accidents, (e.g. lawn mowers, wayward automobiles and so forth) preferably the higher voltage is maintained in the residents housing struture and low voltage is brought to the lamps. If destruction of the mailbox assembly occurs, electrification would not be a result. - As shown in FIG. 3, a conventional mailbox may be modified by the use of a lower plate of galvanized steel46
Galvanized channel 48 is mounted thereon for holding of thelamp retainer 50. Thescreening material 38 is located above the assembly again to prevent damage to the lamps. In such instances, 19 gauge galvanized steel is found to be sufficient to provide support and sufficient rigidity for the handling of most packages. - As shown in FIG. 4, a common voltage source such as 120 volts AC is found in the home and can be delivered to a
low voltage transformer 62 that supplies power to the mailbox locatedswitch 40 andtimer 42. Upon closing of theswitch 40 the timer is energized which allows low voltage power to be delivered to thelamps - Ideally, the Postal worker would only accept mail placed in the residential mail box. The Postal worker would know where the mail came from and that it had been radiated. Similarly, a mail patron would only accept mail from a postal worker after it has been treated by the light radiation.
- It is to be understood that while I have illustrated and described certain forms of my invention, it is not to be limited to the specific forms or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
