DESCRIPTION FOR INDUSTRIAL INVENTION WITH TITLE

?self-supporting device for dispensing liquids with pedal operation?

DESCRIPTION

The present industrial invention relates to a device for dispensing liquids, for example sanitizing gel, for hand cleansing.

After the serious pandemic that hit the entire planet caused by the virus called Covid 19, the WHO (World Health Organization) has imposed frequent hand disinfection on people in order to limit contact contagion. To make disinfection effective? it is necessary to use liquid or gel sanitizing products dispensed automatically or in any case without the direct use of the hands. There are currently several models of dispensing devices available on the market. or less useful for the purpose:

? Dispensers with photocells; this type allows the dispensing of the disinfectant product without touching the dispenser with your hands, in fact ? it is sufficient to bring the latter close to the device where a photocell detects the presence and electronically activates the dispenser. This solution, despite being effective and technologically very advanced, has the drawback of the power supply (electricity): if it is to be connected to the mains, it must be positioned near the power supply. of a source (taken) and the risk of electrocution would still remain; if equipped instead with batteries, it would have the inconvenience (and the cost) of recharging or replacing them.

? Foot dispensers without CE marking; at the moment ? the most typology widespread, but being designed and manufactured without referring to a standard, they expose the user to uncalculated risks. On the market we currently have different types of pedal dispensers or rather different types of material used for their construction: there are wooden products, which have an acceptable average cost but have the disadvantage of being easily perishable (they are in constant contact with liquid substances) and difficult to maintain in terms of sanitation and cleaning; there are stainless steel products, excellent in terms of durability and maintenance but very expensive; finally there are products made of plastic material, which are very cheap but equally fragile and not very durable.

Purpose of the present invention? first of all that of supplying a safe CE marked device designed and built according to the dictates of the Machinery Directive 2006/42/EC described in annex 1, point 2.1 ?machines for food, cosmetic or pharmaceutical products?.

According to a typical but not exclusive embodiment, the self-supporting device for dispensing liquids with pedal operation, preferably made of metal (components in galvanized and painted steel, stainless steel and aluminium), comprises:

- A base in press-folded galvanized and painted steel sheet thick enough to give stability to the device;

- A steel anti-tipping safety plate to fix the device to the floor using special screws and bolts;

- A column closed on three sides to form a C intended to house the moving parts made of press-bent galvanized and painted steel sheet;

An operating pedal made of press-formed aluminum sheet; A movement transmission system made up of a galvanized and painted steel rod connected to the pedal by nut and bolt;

An elastic spring for returning the pedal to position;

An upper movable plate that acts as an actuation pressure for the dispenser made of press-folded galvanized and painted steel plate, connected to the transmission system by nut and bolt;

A mobile shelf made of galvanized and painted steel sheet intended to support the bottle containing the liquid to be dispensed;

A front closing carter placed to protect the transmission parts made of galvanized and painted steel sheet on which? the support for a collection tray for excess liquids is also welded;

A front closing carter made of stainless steel to protect the housing of the bottle containing the liquids to be dispensed;

An upper closing lid made of galvanized and painted sheet steel

- On the left side of the device there are two removable supports for housing other containers, such as plastic bags for the collection of paper or used gloves;

- On the right side of the device ? there is a removable support for housing other containers, for example a pack of latex gloves; From the description provided above, further advantages of the self-supporting device for the dispensing of liquids with pedal operation are highlighted, more specifically listed below:

- The support shelf for the container of the liquids to be dispensed? positionable in pi? positions in order to accommodate bottles/containers from a few ml up to a maximum of 2 litres.

In order to better understand the operation of the self-supporting device for dispensing liquids with pedal operation, in one embodiment thereof we describe the details below:

the control pedal (19) with the pressure of the foot acts on the transmission rod (6) transferring the motion to the presser (1) for the activation of the dispenser (pump device integrated in the bottles usually on the market) placed on the bottle (4) favoring the exit of the liquid; the pressure on the control pedal (19) and the relative downward stroke tension the spring device (12). Releasing the control pedal (19) the spring device (12) contracts bringing the pedal (19) back to the starting position (reset); moreover, always during the release and return phase of the control pedal (19) also the presser (1) rises, allowing the dispenser placed on the bottle (4) to suck the liquid contained in the latter and make it available to spill for the next press.

From what has been described in the previous paragraphs it is easy to understand further advantages of the self-supporting device for dispensing liquids with pedal operation:

1. The possibility? to house bottles of liquid up to 2 liters (thanks to the various positioning levels of the support shelf (5) on the various positioning supports (25)) increases the autonomy of the device by avoiding continuous topping up or replacing the bottle, but above all by limiting the risk of leaving the user without a disinfectant, increasing the risk of contagion;

2. The adoption of the anti-overturning safety plate (16), which allows the device to be fixed firmly to the floor, makes the device particularly safe even if it is used by children or the elderly; ? it is also an important deterrent for theft attempts.

3. The protective casing (8), in an embodiment example, is constructed of stainless steel, easy to clean and disinfect; being the part that pi? easily comes into contact with the user? the area more subject to contamination, so ? extremely important to make it easy to sanitize.

4. The tray for collecting the liquid in excess or resulting from accidental operation of the device, in the device object of the present patent application, in a typical embodiment, is? removable and ? in stainless steel; this particular construction feature allows the user to always keep the device clean and easily sanitized.

5. device object of this patent application? designed to use bottles of liquid (4) of various shapes and sizes, commonly and easily available on the market, freeing the user from the uneconomic constraint on formats imposed by some manufacturers.

6. The removable side shelf (7) ? a useful support shelf, in an embodiment it could be used to place a box of rubber gloves or a box of sanitizing wipes at the user's disposal; moreover, being removable, it allows to optimize the overall dimensions during the transport of the device.

7. The removable support (17) in combination with the removable tray (18) form a very useful support system. In a typical embodiment they can be used, for example, to house a plastic bag to be used as a waste holder (for example for used gloves or used wipes); moreover, since these supports are removable, they optimize the overall dimensions during transport.

8. The self-supporting pedal-operated device for dispensing liquids object of the present patent application, in a typical but not exclusive embodiment, is? made entirely of metal (galvanized and painted steel, aluminum and stainless steel), this feature, in addition to making the device very robust and stable, also makes it durable over time, maintenance-free and easy to sanitize.
