Description

Description of the industrial invention entitled: ?HYGIENIC SANITARY DEVICE FOR CLEANING AND SANITIZING THE SOLES OF SHOES FROM DUSTS, VIRUSES AND BACTERIA, USING SANITIZING AGENTS?;

The present invention relates to the sanitary sector and more in particular, a device for cleaning and sanitizing the sole of shoes and footwear in general while they are worn by the user, cleaning up the entire bottom or contact surface of the shoe itself, with the peculiarity of to totally eliminate the viruses and bacteria present, thanks to the use of a multitude of nozzles, which, if subjected to pressure, release a jet of disinfectant, preferably alcoholic, with an additive consisting of chlorine and paracetic acid which? strongly ovicidal. Scope of the invention

? well known, that the home and the workplace are the places where we spend most of the time in our lives: the home environment and the work environment are very important in determining people's health.

AND? otherwise? known that a bad domestic environment and/or an unhealthy workplace can cause acute or chronic illnesses which, in the end, not only make one feel ill and worsen one's state of health, but lead to very serious indirect consequences, such as loss of working days, loss of serenity? family, increased expenditure on medicines and buffer remedies to solve health problems that could be addressed in other ways.

It would be enough to imitate the good habit of the Rising Sun, which makes you leave your shoes before entering a house, to improve the hygiene of the place where you live and prevent dirt and bacteria, transported by shoes, from settling between the home walls. AND? It is well known that soles, by trampling on the ground all day long, especially on the street, become a receptacle for dust, viruses and bacteria, and carry spores and dirt of various kinds which we carry inside the house at the end of the day.

Keep in mind that through shoes, the bacteria and parasites contained for example in dog excrement are brought into our homes and can transmit even serious infectious diseases. These ?guests? unwanted then accumulate on the floors, carpets, walls and furniture: ? a fact which, especially for children, involves the risk of being infested with worm eggs, if they come involuntarily into contact with canine excrement.

The larvae, which consequently migrate into the tissue, such as impetigo in children, the cause of serious skin infections, can cause, depending on the location, a series of symptoms, causing, albeit rarely, even lethal diseases.

Numerous attempts have been made to address these problems, but they are not fully satisfactory. For example, the so-called adhesive mats (" tacky mats " ) have been proposed for some time, which are placed in front of the entrance to an operating theater or a controlled bacterial environment which, however? have not been shown to reduce the bacterial load of footwear, nor? to reduce the risk of infections in general.

Even the so-called overshoes that are worn in intensive care units and operating rooms, while they can protect operators from exposure to blood and other body fluids during an operation, are not? never been shown to reduce the risk of post-operative site infections or the bioburden on the operating room floor.

AND? therefore the need for a device is strongly felt, to be positioned in the path between a dirty area and a clean area, able to effectively clean the footwear before entering any type of clean environment. Even with the Covid 19 pandemic, this invention could prove to be very useful for countering the spread of the virus, in fact, it could be located at the entrance to any pedestrian crossing, fairs, concerts, schools, pharmacies, supermarkets, airports, railway stations , subway, doctor's offices, lifts, etc. to sanitize shoes. In this way it would be possible to avoid transporting the Virus to undesirable environments, thus avoiding useless infections.

A preferred embodiment of the present invention, for use against the Covid virus, is It was designed with a frame that supports a pedestrian canopy, which houses a thermal camera and a flashing light. Both devices, when they detect a body temperature that is different from the normal one, block the passage of the pedestrian, keeping the control barrier closed, while also activating the flashing light and relative acoustic signal, which alerts the safety personnel.

Main task of the present invention ? to provide a device designed to sanitize and cleanse, even the most? difficult of the soles, clean in depth? and destroy viruses and bacteria that lurk in them and that we deposit on the floors every day. AND? advantageously usable both in the domestic environment to protect private homes and in the workplace or public environment, at the entrance to an operating room or a controlled bacterial load environment, in order to reduce the risk of infection and the overall level of contamination of a environment subject to particular health and hygiene protocols.

There? ? been obtained using a device that cleans the soles of the shoes as we pass by, disinfecting them before entering any type of environment, not only at home but also in those environments where a particular health and hygiene protocol is required, such as intensive care rooms, operating theatres, dental offices, etc.), guaranteeing a barrier effect for the transmission of microorganisms which are carried from the floor to another area.

Further characteristics and advantages of the invention will become apparent from the detailed description which follows with reference to the enclosed drawings which illustrate a preferred embodiment thereof,

In the tables:

the fig. 1 shows a schematic plan view seen from above, for domestic use, equipped with a floating treading grille, as well as a of the lateral sections;

the fig. 2 shows a plan view of the device for domestic use with the nozzles distributed within the footprints reported on the treading surface of the mat, as well as a cross section;

the fig. 3 ? a schematic view of the modular model that can? be installed in lifts and which highlights the location of the sanitizing micro-nozzles and its geometry;

the fig. 4 ? a schematic view of the device for public use, in particular but not exclusively against the Covid 19 virus, where is the invention? subjected to substantial pedestrian crossing flows, which highlights the fact of being equipped with a surface to walk on, a frame that supports the canopy, equipped with a thermal imaging camera, acoustic alarm, flashing light and control barrier;

the fig. 5 schematically shows the shapes for recognizing the geometry of the footwear; the fig. 6 ? a diagram of the constructional structure of a pressure activated micro nozzle.

The device object of the invention looks like a common walkable surface, but equipped with an area characterized by multiple micro-nozzles which come into operation as a result of the foot being placed, when they are subjected to load pressure (fig. 6). In this situation, a programmable electronic device of the PLC type, thanks to its internal programming, detects the geometry of the footwear and sprays the disinfectant in correspondence with it, omitting operation outside the aforesaid geometry (fig. 5).

The opening of the micro nozzles detaches the dirt and the dirt removed from the soles is collected in a special collection container below, which has an easily removable self-cleaning filter.

In a second embodiment, preferably intended for domestic use, in order to contain costs,? instead, a mat is provided in which the micro-nozzles are present only in correspondence with a pair of footprints of the user's feet, the latter must step on it, pausing briefly to receive sanitization through the jet of nebulised disinfectant from the bottom to the top. high.

According to a peculiar feature of the invention, ? an electronic control system capable of recognizing a shoe? This peculiarity ? particularly useful if the invention is installed in lifts: in this case only the geometric shapes of the shoes have to be cleaned, neglecting the different pressure points such as, for example, dog footprints, shopping bags, etc.

According to the invention a first production line provides a device intended to be installed in lifts, in the obligatory entry paths to intensive care rooms, operating rooms, etc. which as represented in fig.3. ? square in shape and modular.

An embodiment for home use, ? instead represented in Fig. 2, in which the device has a walking surface, consisting of a double imprint, where the micro-nozzles are located below, which come into operation, i.e.? emit disinfectant splashes when subjected to load pressure.

The jet, as seen in fig. 3, ? preferably timed, using a timer that can? only be checked by a specialized technician.

The micro nozzles, thanks to the PLC electronic control, come into operation only when the system recognizes the well-defined geometry of the shoe, as shown in figure 5.

- Pointed sole with men's heel;

- Unique sole for men/women;

- Sole with stiletto heel;

- Sole with heel;

The dirt removed from the footwear, in domestic systems, is collected in an easily removable container to allow periodic cleaning.

For the version for public/industrial use ? preferably provided with a self-cleaning system.

The technological innovation described up to now, ? easily positioned in the path between the dirty and clean area, cos? to "force" users to pass and therefore to clean the soles of their shoes.

As can be seen in fig. 2 such the device ? consisting of a low container with an upper walking surface where the two footprints are located on which those who enter the house ? invited to overlap the sole of their shoes before entering the internal rooms of the house itself.

In fig. 6 it can be seen that on one of the sides of the mat a housing 14 protrudes vertically in the interior of which ? placed the tank that houses the disinfectant liquid, while on the opposite side? the pump 16 which delivers the disinfectant to the various micro-nozzles 8 is located.

Preferably, this device ? positioned externally, next to the entrance door of an apartment, but can? also be placed immediately after the door on the visitor's path line.

Preferably, the nebulizers are equipped with needle valves which are controlled by the pressure exerted by the user?s foot.
