Description

HYGIENIC DEVICE FOR SANITARY FITTINGS

The present invention refers to a hygienic device for sanitary fittings.

The hygiene, during operations, of sanitary fittings and of their settings has always been a problem caused by compromises and false shames. Said problem is due to many factors, including not only the execution of the civil works and of the facilities, but also the good manner level of the users and the efficiency of maintenance service.

When a toilet room maintained in bad conditions is entered, the uncomfortable feeling, which may even make anyone turn back, is caused by uncomfortable smells and sights. A smelling toilet room is the result of an insufficient ventilation and of the presence of residual waste of unwanted stagnant materials, which have contaminated the existing structures, in particular the sanitary fittings

(bowls or water closets, Turkish toilets and urinals) , which require a proper use and a constant cleaning; further, the physiologic functions themselves originate smells which should be quickly eliminated. The time deterioration of the sanitary fittings is often due to the flush water which, due to insufficient flow or to its physical and chemical characteristics, does not wash properly the surfaces, causing calcareous formations and various deposits. Further, their perfunctory cleaning will not efficiently clean or sanitise hidden or difficult to reach surfaces, as, for example, the inner edges and the flush water cavities. As a consequence, the unwanted organic materials and other waste materials carelessly introduced (e.g., condoms, sanitary napkins, various wastes) , when lately or partially removed, may create infectious spots with consequent exhalation of unpleasant odours. Since there is not the possibility of intervening afterwards on the structures of the sanitary facilities and since a scheduled control system is not feasible for the proper use nor for the maintenance of the sanitary fittings, the hygienists tend to suggest prophylactic measures or more comfortable arrangements suitable to oppose the effects harmful to the health and to the needs of the users.

Having acknowledged the usefulness of the products of current use, which products solve only shortly the problem of cleaning and sanitising the sanitary facilities and fittings, the interest has been devoted to the realisation of systems suitable to assure a lasting, global and efficient action. In regard to the quality of the air in the sanitary facilities, long lasting deodorant or scenting products have been introduced in the market since long, said products may be simply attached to the wall or may be plugged in an electric outlet, with the task to mitigate or absorb the bad odours .

If the specific problem of the hygiene of the sanitary fittings (water closet, Turkish toilets, urinals) is taken into consideration, there are, currently available, long lasting action products for the preventive treatment of the flush water, which acquires cleaning and/or sanitising properties such that its traditional cleaning action is efficiently performed. In consideration of the growing success obtained by these products, it is interesting to list them on the basis of their different uses:

1 - products to be installed to the supply piping of the flush water: these products are quite complex devices, which are inserted in the water piping before the sanitary fittings, and which require skilled workers for the instalment. The usefulness of such products is low due also to the specific maintenance.

2 - products to be installed in the flush water tank: these products come in tablet form (chemical compounds) to be put directly into the water and therefore the application is possible only in those, very limited, cases wherein the flush tank is mounted externally and an easy inspection is attainable. 3 - products to be installed inside the sanitary bowl (water closet) : these products are in the form of small cages, which contain a specific chemical compound and are positioned under the inner wall of the perimetric edge of the water closet, said products come into contact with the flow of the flush water. The assembly requires a suspension hook which is engaged to the upper wall of the perimetric edge of the sanitary fitting. This product, since it has had the highest commercial success, has been the object of a market survey, which has pointed out some positive features, as the ease of assembly, the low cost and a substantial efficiency in the treatment of the flush water and of the air of the facilities, opposed to various disadvantages. In particular, there are the following disadvantages:

- a particularly serious danger is the careless exposure and the fact that said products, which are toxic and irritant, are easy to reach especially by children;

- problems in the recurring cleaning of the perimetric edge of the sanitary fitting, since said cleaning requires the frequent removal of the installed cage;

- questionable aesthetic look due to the fact that the product essentially projects from the perimetric edge of the sanitary fitting, with the possibility of being contaminated by the physiologic wastes themselves;

- the engagement system, in spite of being standard, does not fit properly with the variable profiles of the perimetric edges of the existing sanitary fittings, causing, sometimes, an unstable instalment; - the support area of the cage cannot match all the different configurations of the inner walls of the sanitary fittings, causing unstable fixing as well as efficiency losses; - the location of the cage in relation to the flow of the flush water does not assure a uniform action on the total surface to be treated, since said location is random and covers only a very limited portion;

- the small dimensions do not allow to hold a significant amount of chemical compound.

A purpose of the present invention is to define a hygienic device for sanitary fittings which over comes the above mentioned disadvantages.

A further purpose of the present invention is realise a detergent or deodorant hygienic device for sanitary fittings, easy to use and suitable to be plied to any kind of commercial sanitary fittings.

Another purpose of the present invention is to define a hygienic device for sanitary fittings which is easy and inexpensive to release through a manufacturing process which does not require complex or expensive technologies.

Said purposes are attained by hygienic device for sanitary fittings according to claim 1 to which reference should be made for brevity. The hygienic device according to the invention comprise a flexible element to be installed within the upper perimetric edge of the sanitary fittings; the fixing is obtained without external engagements .

In turn, the flexible element comprises one or more than one perimetric profiles, integrated or modular and adjustable by the user to the desired length and shape, in order to be configured according to the specific existing inner surfaces of support of the sanitary fittings. The self-blocking of the sanitary fittings is obtained through the expansion of the perimetric surface of the flexible element of sanitary fittings inner edge. The flexible element has a structure suitable to contain compositions of natural or chemical substances, under solid, creamy, jelly and granular form, said substances, thanks to their detergent, sanitising, decalcifying, solvent and scenting characteristics are suitable both for the flush meter treatment and for the treatment of the air in the facilities.

Further process and advantages of the present invention will be clear from the following description and from the attached drawings, provided as a non limiting example, in which:

With reference to the above figures, numeral 111 indicated a traditional cage, hanging from the upper perimetric edge 3 of a water closet (WC) , wherein the detergent and/or deodorant substance is contained.

Numeral 1 indicates a hygienic device for sanitary fittings according to the present invention , which is installed inside the lateral perimetric edge 2 of water closet (WC) , in a protected position and, if desired, unseen to the eye. The device 1 is suitable to distribute specific substances (sanitizers, purifiers, deodorants, perfumes, detergents, decalcifying agents, etc.) suitable for the treatment of the flush water and of the air in the facilities. Numeral 4 indicates an annular chamber defined by the perimetric edges 2-3 of the sanitary bowl, and the water flow, independently from the embodiment of the sanitary bowl, is directly discharged through said chamber and is directed against the hygienic device 1. Figure 4 is similar to Figure 3, but it refers to a different configuration of the perimetric edges 2-3 of the sanitary bowl, according to this configuration an inner annular chamber 222 is provided, wherein the flush water is directed before flowing through a plurality of cavities 444 and, then, over the underlying device. In a preferred non limiting embodiment of the present invention, the hygienic device 1 for sanitary fittings comprises a flexible element 333 and a coaxial tube 44, integrated therewith, in such a way that the structure so obtained has a substantially annular shape, in order to release the instalment, inside the sanitary fittings, of at least one distributing element 30, 3', 3'', suitable to hold and to conveniently release the specific detergent and/or deodorant substances therein contained. The distributing element 30, 3^f, 3'' is fixed, steadily, to the flexible element 333, by means of a hook 6 (figure 5 and 6) . It is to be noted that the flexible element 333 can be conceived for having the distributing element 30, 3', 3" installed onto it, as shown in Figure 5, with the possibility of removing and substituting it; otherwise, said flexible element can integrate the technical- functional characteristics of the distributing element, as shown in Figures 2,3 and 4.

The flexible element 333 and the coaxial tube 44 can be easily installed along the inner perimeter of the upper perimetric edge 3 of the sanitary fittings and in particular of the water closet (WC) , since they are mostly used; the fixing is achieved by self-blocking means, easy to remove without inconvenient devices of engagement to the outer upper edge of the sanitary fitting.

In consideration of the fact that the sanitary fittings have the most different ways of embodiment, the element 333 and the tube 44 can assume both the configuration of the inner contact wall and the to change their length in order to match the different perimetric lengths.

The general criteria of realisation, in order to comply with the above mentioned requirements (protected positioning, variable configurations, adjustable length, distributing means assembly, self-fixing) , is inspired by the basic idea to have a flexible profile both for the element 333 and for the tube 44, even they have a different structure, since they are complementary to each other. Further the flexible profile of the so obtained annular structure is sufficiently elastic and capable of being deformed, suitable to stand squeezing of the section and axial torsion forces and suitable to be compressed along the horizontal axis of the perimeter (elastic change of the length by compression) ; as a consequence, thanks to the above structural features, when the hygienic device 1 is put in abutment contact with the inner wall of the sanitary fitting it matches the perimetric configuration by adhering to the existing curvature and by maintaining its own coaxial positioning in respect to both the horizontal plane and the vertical one. The element 333 has a tubular section non necessarily circular, characterised by an alternate sequence of protrusions, indicated by the letter R and of cavities indicated by the letter I, said sequence enables the element to sustain a certain axial compression, while the tube 44, suitable to slide coaxially within the element 33, has a full or hollow section as the one shown in Figure 7 smaller than the element section. The so obtained hygienic device 1 can be arranged to change its length between a maximum and a minimum value an to adjust it to the different perimetric length of the known sanitary fittings; as a consequence there is the need to reduce the maximum length or to increase the minimum length, by integrating in the basic perimetric length the actual excessive length.

Considering that the device 1 comprises a flexible profile having two ends to be connected together, in the case that a maximum length is adopted, it will be necessary to provide an overlapping of the ends or the axial length of one end within the other, while in the case a minimum length is adopted, as shown in the example of Figure 5, it will be necessary to insert, between the two ends 5 and 5' of the flexible element 333, another flexible profile 44 having the function of connecting the two ends, said additional profile has one extremity fixed to the end 5' and the other extremity is free to slide within the element 333; the change in the length of the arc K of the tube 44 defines the perimetric length of the "annular" element. The hygienic device 1 is fixed inside the perimetric edges 2-3 of the sanitary fitting, by means of a specific device suitable to block at the required value, through a defined strength, the perimetric length of the whole flexible profile.

Said device comprises essentially two components in combined action, said components can be indicated as "friction slider" and "graduated matrix". In the example of Figure 5, the friction slider is positioned at one end of the tube 44, which can slide inside the element 333, which, as shown in Figure 7, has an inner tubular section, characterised by a plurality of protrusions R and of cavities I and therefore said tubular section has the function of a graduated matrix; the friction slider 7 is characterised by a bulging end, which is flexible and suitable to be compressed as well as to slide within element 333.

Figure 8 is a front view of the slider 7, which can have, if desired, radial notches, indicated by the letter T, having the purpose to enhance the structure flexibility; Figure 9 shows, with a dashed line, the slider 7 possible deformation from one first to a second configuration (this last configuration being indicated by 7A) , with consequent change of its own outer diameter. Figure 10 shows the slider 7 which, by means of a tangential force, indicated by arrow F, which is applied manually by the user on tube 44 in the indicated direction, completes a sliding movement inside element 333 with a stopping motion alternating stops (blocking) and free advancements (releases), due to the different friction strength of the protrusions R and of the cavities I, which have enlarged and reduced through sections respectively.

With particular reference to Figure 7, the slider 7 is in the rest configuration, i.e. in the blocked position with a blocking point inside element 333, when a desire value of the perimetric length is achieved.

The adjustment of the arc K length of the tube 44 is obtained through a manually action of the user, by pulling closer or by moving away the two ends 5, 5' of the element 333, therefore causing the sliding movement of the slider 7 in the graduated matrix.

Moving away the ends 5, 5", i.e. by increasing the arc K length, can be realised through semiautomatic systems, i.e. by substituting the manual operation with mechanical devices (springs) or devices based on the fluid dynamic expansion. The gradual action of the blocking device, during the instalment of the hygienic device 1, realised through the progressive increase in the length of the annular structure, causes the movement of the annular structure toward the upper position of the sanitary fitting and the subsequent blocking against the inner perimetric edge, as shown in figures 2, 3 and 4.

Since the blocking device of the perimetric length does not allow a free change in length of the flexible element 333, unless through a specific manual action, a self- blocking of the hygienic device 1 is obtained, without any downward movement, since all the sanitary fittings have a funnel vertical section, i.e. with a downward decreasing section which ends with the connection to the discharge duct. The specific annular and flexible structure of the hygienic device 1 is suitable to receive the assembly of one or more distributing elements 30, 3', 3'' of deodorant and/or detergent substances. Further, the hygienic device 1 can have the distributing element 30, 3', 3'' substituted; in such case the removal and the assembly of the spare parts are realised through a quick connection mechanism (e.g. a pressure, engagement, expansion, magnetic attraction device) positioned on the fixed portion (element 333) or on the mobile portion (distributing element 30, 3', 3'¹)-

In a specific non limiting example of embodiment, the distributing element 30, 3', 3'' has, in the upper portion of its structure, U-shaped engagement means 6, capable of being deformed and suitable to snap-engage the flexible profile of the upper element 333. The hygienic device 1 can be disposable, after the content consumption of the distributing element 30, 3', 3''; naturally, in this case, the mobile engagement among the elements 30, 3', 3'' of the hygienic device 1, according to the composition of the contained substances, has a specific treatment both of the air in the facilities and of the flush water flow (which comes in contact with said distribution element from time to time) according to the frequency of use of the sanitary fitting.

While the air treatment, which is obtained by use of purifier, deodorants and/ or perfumes, is a self- contained process, the flush water, after treatment, has to perform a diversified action which concerns the sanitary fitting (relative to the sanitising, detergent or decalcifying properties) , the cesspools and the sewers (relative to the draining properties and to the substances, germs and bacteria dissolving properties) . The structure of the distributing element 30, 3', 3'' is, therefore, also affected by, besides the physical state of the contained substances (solid, creamy, jelly, granular form, etc.), the dynamic of the air and water treatment process. In the case of a solid compound, the distributing element 30, 3', 3'' may not require a containment structure, since the substance compound, due to its cohesion, have a direct interaction with the involved fluids (air and water) and reach a progressive exhaustion. Naturally the solid compound, having an integral or modular structure, will require a simple system for the fixing or the integration to the annular element 333, and protective means for its handling before the instalment

(for instance, a transparent, self-dissolving film) .

The containment structure of the contained substances will need, on the other hand, proper openings to favour the desired exchange, i.e. the passage through of the fluids to be treated (water and air) .

While the treatment of the air in the facilities does not require a specific attention, since it is sufficient to provide, in the structure of the distributing element 30, 3', 3'' an adequate opening for the continuous and free flow of air, the treatment of the flush water is the object of a particular analysis, since it is necessary to evaluate how often the sanitary fitting is used, and the direction and the strength of the water flows, which through the flushing cavities 444, positioned along the inner perimetric edge 222, come in contact with the distributing element 30, 3', 3'' and go through its inner section.

The outcome is a cage structure, designed with a reduced thickness, since said dimension has to have, possibly, the same or a smaller width in comparison with the width of the inner perimetric edge 222 of the sanitary fitting, which is in direct contact with said cage. Such feature enables the distributing element 30, 3' , 3 ' ' not to protrude from the perimetric lateral edge 2 of the sanitary fitting and to be, therefore, protected and partially out of sight from the outside.

Since a complete fitting of the distributing element 30, 3', 3'' inside the annular cavity 4, under the perimetric edge 3, is also attainable, said element can be completely hidden (to such purpose, see Figure 2) .

Naturally, .the axial length and the height of the distributing element 30, 3', 3 ' ' define the load capacity of the substances to be used. The height does not pose any particular problem, except for aesthetic reasons related to the sight exposure to be given to the hygienic device 1, while the length can be equal to the full length of the flexible device 333. Therefore, the cross section of the distributing element 30, 3', 3'' can be substantially circular or can have an elongated dimension along the vertical axis (rectangular configuration) , in the case it is required to increase the whole volume, both for the purpose of containing a larger quantity of chemical compound and of creating a holding tank of the water flow going therethrough. This last feature gives the distributing element 30, 3' , 3'' a particularly interesting characteristic, since, after the water stops flowing, there will be a slow and continuous drainage of the water held in said tank, in function of the dimensions of the openings obtained in the bottom of the tank structure. In any case, the structure of the distributing element 30, 3', 3'', since it has to be in contact with the supporting wall, has the capability of being deformed and has elastic characteristics similar to the ones of the flexible profile structure to which is steadily fixed. For the purpose of increasing the involved surface and therefore the efficiency, a plurality of single or integrated distributing elements 30, 3', 3'' are provided, said elements are conveniently located along the full length of the annular element 333 (see Figure 5) . An alternative, non limiting embodiment of the hygienic device 1, according to the present invention, provides the integration of the flexible element 333 and of the coaxial tube 44 with the distributing elements 30, 3 ' ' (said embodiment is shown in Figures 12 and 13) . Said design solution allows both the substitution of the exhausted distributing elements 30, 3'' and the whole substitution of the hygienic device 1.

Figure 12 shows the symmetric mirror structure of the hygienic device 1, wherein the left semicircle and the right semicircle have the same technical and operational characteristics, since they comprise, respectively, the flexible elements 12 and 12' and the distributing elements 3 ' ' and 30. The intermediate coaxial tubes 14 and 14', having the function of variable length connection between the two semicircle structures, are shown in the minimum perimetric length arrangement, wherein their ends 17, 17' and 18, 18' (corresponding to the friction slider 7) are fully inserted into the tubular sections of the flexible elements 16, 16' and 12, 12' (corresponding to the graduated matrix comprised in the element 333) . Figure 13 shows the hygienic device 1 of Figure 12 with the intermediate coaxial tubes 14 and 14' in their maximum perimetric length arrangement, since their ends 17, 17' and 18, 18' (corresponding to the friction slider 7), due to a manual action performed on the two pairs of appendices 50, 50' and 55, 55' along two opposed directions, indicated by arrows F' , F' ' , have been subjected to a sliding movement outside the flexible elements 16, 16' and 12, 12' (corresponding to the graduated matrix) , said movement has shown two arcs of maximum extension of the intermediate tubes 14, 14', said arcs are indicated with K' , K", respectively. The sliding system of the ends 17, 17', 18, 18' into the elements 16, 16', 12, 12' is the one described above for the embodiment of the hygienic device 1 of Figures 5-11. The distributing elements 30, 3'', integrated in the annular struture formed by the elements 14, 16', 12', 14', 12, 16 can naturally be subjected to axial deformations in order to fit inside the inner surface configuration of the supporting sanitary fitting. As already mentioned, the two ends of each single distributing element can be steadily integral with the flexible profiles (in the disposable version of the hygienic device 1) or they can have a not fixed engagement in order to allow the removal and the substitution of said distributing elements (in the version which allows to substitute the exhausted distributing element 30, 3', 3'' and to still use the hygienic device 1) .

The structure of the distributing element 33, 3'' comprises a tubular flexible element with rings 9, which is formed by an alternate sequence of protrusions 9R and cavities 91, wherein, in the central core, the detergent and/or deodorant chemical compound is placed, in a solid or semi-solid state. The inlet and the outlet openings for the air and for the flush water are indicated by the letters A and U respectively, said openings are provided nearby the annular protrusion 9R. Since the water flow, that runs against the distributing element 30, 3', 3'', is turbulent, in order to enhance the flow through the tubular element 9, the inlet opening A and the outlet opening U are , at any subsequent protrusion 9R, rotated by an angle to reach the positions A' and U' respectively.

An alternative, non limiting embodiment of the distributing element 30, 3', 3'' provides in correspondence of the lower portion of the annular protrusions 9R of the tubular element 9, a plurality of cavities 11, which form true traps to contain the water flow.

In such case, the outlet opening U, obtained on the bottom of the cavity 11, has purposely reduced dimensions, in comparison with the previous embodiment, in order to slow down the water drainage and to realise a time adjusted release of water. Finally, also in this case, the inlet opening A' of the water flow has different angular positions in order to enhance the flow in the presence of turbulent motion, according to the above description. From the above description, the characteristics and the advantages of the hygienic device for sanitary fittings of the present invention shall be clear.

In particular the characteristics and advantages of the hygienic device are:

- possibility to be installed inside the perimetric edge of sanitary fitting, in such a way that it is protected and, if desired, out of sight from the outside;

- easy fixing system, without any external engagement; - widespread use for all the different types of sanitary fittings;

- opportunity, for the user, to adjust manually the perimetric length of the device in order that it matches the specific shape of the sanitary fitting; - possibility of chemically treating both the flush water and the air in the facilities by means of distributing elements of detergent, sanitising, decalcifying, solvent, scenting, deodorant substances;

- efficiency in the treatment process, obtained through the extended annular length of the distributing element, which has a larger exchange surface between the chemical compound and water-air, and a total control of the inner surfaces of the sanitary fittings.

Finally, it is clear that several other changes may be realised in the hygienic device for sanitary fittings of this invention, without departing from the innovative principles of the invention, as well as it is clear that, in the embodiments of the invention, the materials, the shapes and the dimensions of the described details may be different according to the needs and said details may be substituted by other technically equivalent details. Therefore, for instance, the number and the position of the distributing elements may be changed, as well as the number and the position of the connections and of the adjustment and blocking devices of the annular structure of the hygienic device. In the same manner, the flexible profile of the annular element can comprise one or more parts, linked together by fixed or movable engagement systems; in this case, the adjustment of the total length of the perimetric length can be put in several positions, with the placement of additional blocking devices.
