PATENT FOR INDUSTRIAL INVENTION ENtitled:

?PORTABLE DEVICE FOR THE DISINFECTION OF PEOPLE AND/OR GOODS IN TRANSIT THROUGH A GATE?

DESCRIPTION TEXT

Technical field

The present invention relates to a portable device for disinfecting people and/or goods in transit through an opening, of the type specified in the preamble to the first claim.

Basic evolution (known technique and technical problem) The devices for sanitizing people and/or goods are currently known, such as for example the different types of devices that are installed with dedicated boxes or with structures installed by assigned personnel, said devices placed near low-frequency pedestrian entrances such as small businesses? commercial, banks, corporations, condom?ni entrances, or more.

Said devices are generally suitable for the disinfection and sanitation of people and/or goods entering or leaving a gate with a plurality of of different technologies such as UVGI radiation, ionization of the air or the formation of fog or aerosol with a suspension of disinfectant product or more.

Examples of said devices are described in documents KR20110031810A and WO 2011/052023A1.

Document WO 2011/052023A1 for example describes a disinfection system able to be placed at entrances in order to create a closed corridor inside which a disinfection system operates.

The document KR20110031810A instead describes a device able to be installed above an opening, for example a door, said device able to sterilize, with UV radiation, air which will then come sent on the gate by a system of blowers. According to the document, said air and said radiation disinfect people or objects in transit through an opening, creating a disinfectant barrier.

The prior art described includes some important drawbacks.

In particular, the devices of the type described in the document WO 2011/052023A1 include the assembly and/or assembly of bulky walls, roofs or covering canopies in order to create the corridor or closed volume in which the disinfection takes place, preventing the rapid installation of such a device or even the do-it-yourself installation without specialized personnel. Finally, even if similar devices are often additionally equipped with wheels, their applicability? to a plurality? of different gates? always blocked by the encumbrances and by the necessity? to design the ad hoc solution.

Again, the device described in KR20110031810A provides for installation by specialized personnel and furthermore is not? movable and / or mobile to meet the needs? of a user, who, for example, must equip another passage in the same building for disinfection.

Summary (technical task)

In this situation, the technical task underlying the present invention? devising a portable device for the disinfection of people and/or goods in transit through an opening capable of substantially obviating at least part of the aforementioned drawbacks.

In the context of this technical task ? an important object of the invention is to obtain a device which can be installed easily, without the need for structural works or specialized personnel for installation.

Another important purpose of the invention ? create a device that is portable, quickly movable from one opening to another, for example in the case of variations in the quantities? and frequency of passages through a plurality? of interconnected steps.

In addition, an important purpose of the invention is create a device with a flexible use, applicable to any type of structure, not only to passages such as doors but any point of passage between two or more? environments and/or delimited areas.

Again, an important object of the present invention ? create a high safety device, which allows the use of low pressures in the pumping system and in the entire fluid circuit.

Finally, an important purpose of the invention ? create a device not specifically designed for the application gate, without the need? of substantial modifications in the finished device for different and/or multiple applications.

The specified technical task and aims are achieved by a portable device for the disinfection of people and/or goods in transit through an opening, as specified in the attached claim 1.

Preferred technical solutions are highlighted in the dependent claims.
