?COLONNA DI DISTRIBUZIONE DI SOSTANZE FLUIDE DI VARIO GENERE? ?DISTRIBUTION COLUMN OF FLUID SUBSTANCES OF VARIOUS KINDS?

L?invenzione si riferisce ad una colonna di distribuzione di sostanze fluide di vario genere, ed in particolare di gel igienizzante, di sapone, di crema e di pasta lavamani. The invention refers to a column for distributing fluid substances of various kinds, and in particular sanitizing gel, soap, cream and hand washing paste.

Attualmente, per la distribuzione di sostanze fluide di vario genere, in particolare, di sapone, crema, pasta lavante e simili, in ambienti pubblici (scuole, ospedali, servizi pubblici, ecc.) ed in ambienti privati (abitazioni, aziende, uffici ecc..), vengono normalmente utilizzati dei contenitori che vengono applicati a pareti, muri degli ambienti, e nei quali vengono introdotte le relative sostanze, e tali contenitori sono realizzati con uno scarico sottostante, chiudibile da un rubinetto o valvola, che vengono azionati in apertura manualmente da ogni utente, per il tempo necessario ad erogare la quantit? desiderata di tale sostanza, ed al termine di quest?operazione tale rubinetto o valvola si riporta automaticamente nella posizione di chiusura, impedendo l?erogazione di ulteriore sostanza. Questi tipi di apparecchiature presentano l?inconveniente di richiedere il contatto dell?utente con le loro parti componenti, in questo caso con il contenitore, il rubinetto o la valvola, per potere svolgere l?operazione di erogazione della sostanza, e questo fatto risulta igienicamente pericoloso, dato che queste parti componenti possono venire toccate anche da altre persone, col possibile e probabile rischio di trasmissione di agenti infettivi tra le varie persone, e, soprattutto di trasmissione di batteri, funghi o virus, come attualmente il temibile coronavirus Covid 19. Inoltre, un ulteriore inconveniente di queste apparecchiature ? costituito dalla possibilit? di malfunzionamento del rubinetto o della valvola, con conseguente necessit? di manutenzione frequente di queste apparecchiature, o di una loro sostituzione, per assicurare il loro corretto funzionamento. Currently, for the distribution of fluid substances of various kinds, in particular, soap, cream, washing paste and the like, in public environments (schools, hospitals, public services, etc.) and in private environments (homes, companies, offices, etc. ..), containers are normally used which are applied to walls, walls of rooms, and into which the relative substances are introduced, and these containers are made with an underlying drain, which can be closed by a tap or valve, which are operated to open manually by each user, for the time necessary to dispense the quantity? desired amount of this substance, and at the end of this operation, the cock or valve automatically returns to the closed position, preventing the delivery of further substance. These types of equipment have the drawback of requiring contact by the user with their component parts, in this case with the container, tap or valve, in order to carry out the operation of dispensing the substance, and this fact is hygienically dangerous, given that these component parts can also be touched by other people, with the possible and probable risk of transmission of infectious agents between various people, and, above all, of transmission of bacteria, fungi or viruses, such as the dreaded coronavirus Covid 19 currently. Furthermore, another drawback of this equipment? consisting of the possibility of malfunctioning of the tap or the valve, with consequent necessity? frequent maintenance of this equipment, or its replacement, to ensure its correct functioning.

La presente invenzione si propone lo scopo di realizzare una colonna di distribuzione di sostanze fluide di vario genere, come ad esempio gel igienizzante, sapone, crema e pasta lavamani, progettata per superare gli inconvenienti sopra descritti delle apparecchiature attualmente utilizzate per svolgere questa funzione, e atta a svolgere l?operazione di erogazione delle sostanze senza che le mani dell?utente entrino in contatto con le parti componenti della colonna stessa, e con una maggiore affidabilit? operativa. The object of the present invention is to create a distribution column for fluid substances of various kinds, such as for example sanitizing gel, soap, cream and hand washing paste, designed to overcome the drawbacks described above of the equipment currently used to perform this function, and able to carry out the substance dispensing operation without the user's hands coming into contact with the component parts of the column itself, and with greater reliability? operational.

L?invenzione riguarda una colonna di distribuzione 5 di sostanze fluide di vario genere, ed in particolare di gel igienizzante, di sapone, di creme e di pasta lavamani. Questa colonna di distribuzione ? atta a venire installata in ambienti pubblici (scuole, ospedali, servizi pubblici, ecc?), ed in ambienti privati (abitazioni, aziende, uffici, ecc?), per erogare tali sostanze fluide senza che le mani dell?utente entrino in contatto con le parti componenti della colonna stessa, e con elevata affidabilit? operativa. The invention relates to a distribution column 5 for fluid substances of various kinds, and in particular for sanitizing gel, soap, creams and hand washing paste. This distribution column? suitable for being installed in public environments (schools, hospitals, public services, etc?), and in private environments (homes, companies, offices, etc?), to dispense these fluid substances without the user's hands coming into contact with the component parts of the column itself, and with high reliability? operational.

Nelle fig. 1-15 ? rappresentata schematicamente la colonna di distribuzione 5 conforme alla presente invenzione, la quale ? realizzata vantaggiosamente in materiali metallici, come ad esempio l?acciaio inossidabile, l?alluminio anodizzato, oppure in materia plastica. In figs. 1-15 ? schematically represented the distribution column 5 according to the present invention, which is advantageously made of metallic materials, such as for example stainless steel, anodized aluminum, or plastic material.

La presente colonna di distribuzione ? di tipo autoportante ed ? costituita sostanzialmente da una carcassa allungata 6 estesa in senso verticale, e formata da una prima porzione rettilinea verticale 7 di forma parallelepipeda o di altra idonea forma geometrica, ed internamente cava per tutta la sua estensione, e da una seconda porzione rettilinea verticale 8 di forma parallelepipeda, di dimensioni minori di quelle della prima porzione 7, ed unita superiormente a quest?ultima. La prima porzione di carcassa 7 ? delimitata inferiormente da una base piana 9, unita all?estremit? inferiore della prima porzione 7 e di dimensioni maggiori della stessa, la quale viene appoggiata sul pavimento dell?ambiente in cui la colonna 5 ? installata, e tale porzione di carcassa 7 ? inoltre delimitata superiormente da una superficie piana 10 in cui ? praticata un?apertura passante 11, chiudibile da una corrispondente lamiera piana 12, attraverso la quale apertura viene introdotto un recipiente 13 di contenimento della sostanza fluida, detto recipiente venendo appoggiato inferiormente su un sostegno interno 14 fissato nella cavit? interna 15 della prima porzione di carcassa 7 ed essendo provvisto di un?apertura superiore (non indicata), chiudibile da un corrispondente tappo 16, e situata in corrispondenza dell?apertura passante 11. In questo modo, il recipiente 13 ? accessibile dall?alto sollevando la lamiera piana 12 e togliendo il tappo 16, per introdurre la sostanza fluida nel recipiente stesso. This distribution column ? self-supporting and ? substantially consisting of an elongated casing 6 extending in a vertical direction, and formed by a first straight vertical portion 7 of parallelepiped shape or other suitable geometric shape, and internally hollow for its entire extension, and by a second straight vertical portion 8 of parallelepiped, of smaller dimensions than those of the first portion 7, and joined at the top to the latter. The first portion of carcass 7 ? bounded below by a flat base 9, joined to? bottom of the first portion 7 and larger in size than the same, which is placed on the floor of the room in which the column 5 is located. installed, and this portion of the frame 7 ? furthermore delimited above by a flat surface 10 in which ? a through opening 11 is made, which can be closed by a corresponding flat sheet 12, through which opening a container 13 for containing the fluid substance is introduced, said container being rested below on an internal support 14 fixed in the cavity? internal 15 of the first portion of carcass 7 and being provided with an upper opening (not shown), which can be closed by a corresponding cap 16, and located in correspondence with the through opening 11. In this way, the container 13 is? accessible from above by lifting the flat plate 12 and removing the plug 16, to introduce the fluid substance into the container itself.

A sua volta, la seconda porzione di carcassa 8 ? realizzata di forma parallelepipeda con dimensioni minori di quelle della prima porzione 7 e si estende verticalmente verso l?alto per una determinata lunghezza, ed essa ? inoltre sagomata con una cavit? interna 17 comunicante con la cavit? interna 15 di detta prima porzione di carcassa. Nella parte terminale superiore di detta seconda porzione di carcassa 8 ? fissata centralmente un?estremit? di una sporgenza rettilinea 18, di dimensioni minori di quelle di detta seconda porzione di carcassa e distanziata dalla lamiera piana 12, sporgendo sul davanti di detta seconda porzione di carcassa di un? estensione tale da coincidere con l?apertura passante 11. Dall?altra estremit? della sporgenza 18 viene erogata la sostanza fluida, come verr? di seguito descritto, in modo che la stessa giunga sulle mani dell?utente, che vengono introdotte nello spazio compreso fra la lamiera piana 12 e la sporgenza 18. In turn, the second carcass portion 8 ? made in a parallelepiped shape with smaller dimensions than those of the first portion 7 and it extends vertically upwards for a given length, and it is also shaped with a cavity? internal 17 communicating with the cavity? internal part 15 of said first carcass portion. In the upper end part of said second carcass portion 8 ? centrally fixed a? extremity? of a rectilinear protrusion 18, of smaller dimensions than those of said second carcass portion and spaced from the flat sheet 12, projecting on the front of said second carcass portion of a? extension such as to coincide with the through opening 11. From the other end? of the protrusion 18 the fluid substance is dispensed, how will it be? described below, so that it reaches the user?s hands, which are introduced into the space between the flat sheet 12 and the protrusion 18.

In corrispondenza della parte terminale inferiore della prima porzione di carcassa 7 ? fissato in modo articolato un pedale 19, cooperante con un gruppo di pompaggio 20 della sostanza fluida, che ? fissato internamente a detta prima porzione di carcassa ed ? sagomato come verr? di seguito descritto, ed ? azionabile dalla pressione del piede dell?utente, da una posizione di riposo in cui tale gruppo di pompaggio non viene azionato, e la sostanza fluida non viene erogata, ad una posizione di lavoro in cui tale gruppo di pompaggio 20 viene azionato e la sostanza fluida viene erogata, e quando il piede non preme pi? sul pedale, quest?ultimo si riporta automaticamente nella sua posizione di riposo. La colonna di distribuzione 5 viene chiusa posteriormente da uno schienale piano 21, della stessa grandezza della colonna e fissabile contro la parete posteriore 22 di detta colonna mediante viti (non indicate, vedi fig. 5), inserite attraverso corrispondenti aperture laterali 23 dello schienale. In questo modo, quando lo schienale 21 viene applicato contro detta parete posteriore 22, esso chiude le cavit? interne della colonna, e quando ? richiesto l?accesso in tali cavit? interne e nelle parti componenti alloggiate nelle stesse, lo schienale 21 viene svitato e tolto dalla sua posizione di chiusura. Nell?interno della colonna di distribuzione 5 ? inoltre installato sia un primo condotto di circolazione 24 collegato tra il fondo 25 del recipiente di contenimento 13 ed il gruppo di pompaggio 20, per introdurre in quest?ultimo la relativa sostanza fluida, e sia un secondo condotto 26 collegato tra il gruppo di pompaggio 20 e la sporgenza rettilinea 18, per erogare all?esterno la sostanza fluida spinta dal gruppo di pompaggio 20, quando il pedale 19 viene azionato nella sua posizione di lavoro. Viene ora descritto dettagliatamente il gruppo di pompaggio 20, con particolare riferimento alle fig. 9 e 10, in cui viene illustrato tale gruppo spostato nella sua posizione di riposo, ed alle fig. 11 e 12 in cui viene mostrato il gruppo spostato nella sua posizione di lavoro. Il gruppo di pompaggio 20 ? costituito sostanzialmente da un corpo solido cilindrico 27 di lunghezza limitata, che viene fissato sulla superficie interna della base piana 9, e nel quale ? ricavata una cavit? interna 28 in cui risulta alloggiato e scorrevole con una corsa limitata uno stantuffo cilindrico 29, sagomato con un gambo allungato 30 terminante con un?estremit? arrotondata 31, a contatto con un corto lembo rettilineo piegato 32 di una squadretta (non indicata), dotata di un altro corto lembo rettilineo 33 fissato al pedale 19, detto stantuffo 29 essendo sagomato con un risalto centrale allargato 34, a contatto scorrevole con la parete interna rettilinea (non indicata) della cavit? interna 28, ed esso essendo inoltre sagomato all?altra sua estremit? con una testa terminale 35, alla quale si aggancia un?estremit? di una corta molla di reazione 36 alloggiata nella detta cavit? interna. Fra il risalto allargato 34 e la testa terminale 35 ? ricavata una sede (non indicata) in cui ? alloggiata una guarnizione a labbro 37 che, durante lo scorrimento dello stantuffo 29 nella cavit? interna 28, assicura la tenuta ermetica di quest?ultima verso l?esterno, impedendo cos? che la sostanza fluida introdotta in tale cavit? interna possa uscire verso l?esterno. Lo stantuffo 29 ? scorrevole col suo gambo 30 attraverso un foro passante (non indicato) praticato ad una estremit? nel corpo cilindrico 27 e col suo risalto contrale 34 e la sua testa 35 nella cavit? interna 28, il cui diametro ? maggiore rispetto al diametro del foro passante in cui scorre il gambo 30. L?estremit? aperta di detta cavit? interna 28 viene chiusa ermeticamente da un tappo posteriore 38, fissato al corpo cilindrico 27, e contro la parete interna di tale tappo 38 fa battuta e si aggancia l?altra estremit? della molla di reazione 36. In questo modo, quando il pedale 19 viene mantenuto nella sua posizione di riposo (vedi fig. 10), lo stantuffo 29 viene mantenuto nella sua posizione primitiva dalla forza della molla 36 che ? rilassata e non compressa, mentre quando il pedale 19 viene premuto verso il basso e spostato nella sua posizione di lavoro (vedi fig. 12), il lembo 32 del pedale spinge lo stantuffo 29 nella cavit? interna 28, comprimendo la molla 36 verso il tappo 38, e quando il pedale 19 non viene pi? premuto verso il basso la molla 36 si riporta nella sua posizione rilassata primitiva della fig. 10, spingendo pertanto lo stantuffo 29 automaticamente nella sua precedente posizione di riposo. Il gruppo di pompaggio 20 ? inoltre provvisto di un primo imbocco 39 fissato in un?apertura passante 40 praticata attraverso il corpo cilindrico 27 e comunicante con la cavit? interna 28 di quest?ultimo, e nella quale ? alloggiata una valvola unidirezionale 41 per l?ingresso della sostanza fluida, detto primo imbocco essendo collegato con la sua estremit? libera con un?estremit? del primo condotto 24 collegato con l?altra sua estremit? col recipiente 13. Il gruppo di pompaggio 20 ? ulteriormente provvisto di un secondo imbocco 42, distanziato angolarmente dal primo imbocco e separato da esso, il quale imbocco ? fissato in una corrispondente apertura passante 43 praticata attraverso il corpo cilindrico 27 e comunicante con la cavit? interna 28 di quest?ultimo, e nella quale ? alloggiata una valvola unidirezionale 44 per l?uscita e l?erogazione della sostanza fluida, detto secondo imbocco essendo collegato con la sua estremit? libera con un?estremit? inferiore del secondo condotto 26, che nella sua parte superiore ? piegato ortogonalmente (vedi fig. 6 e 15), in modo da formare una porzione di condotto orizzontale 46 alloggiata nella sporgenza rettilinea orizzontale 18 e sostenuta da un sostegno superiore 45, fissato nella cavit? interna 17 della colonna e sostenente anche la restante porzione del condotto 26, detta porzione di condotto 46 essendo aperta alla sua estremit? libera, per l?erogazione della sostanza fluida sulle sottostanti mani dell'utente. At the lower end part of the first carcass portion 7 ? fixed in an articulated way a pedal 19, cooperating with a pumping group 20 of the fluid substance, which is internally fixed to said first carcass portion and ? shaped as it will be? described below, and ? which can be activated by the pressure of the user's foot, from a rest position in which this pumping group is not activated, and the fluid substance is not dispensed, to a working position in which this pumping group 20 is activated and the fluid substance is delivered, and when the foot does not press pi? on the pedal, the latter automatically returns to its rest position. The distribution column 5 is closed at the rear by a flat back 21, of the same size as the column and which can be fixed against the rear wall 22 of said column by means of screws (not shown, see fig. 5), inserted through corresponding side openings 23 of the back. In this way, when the backrest 21 is applied against said rear wall 22, it closes the cavities interior of the column, and when ? required? access in these cavities? inside and in the component parts housed therein, the backrest 21 is unscrewed and removed from its closed position. Inside the distribution column 5 ? also installed is a first circulation duct 24 connected between the bottom 25 of the containment vessel 13 and the pumping unit 20, to introduce the relative fluid substance into the latter, and a second duct 26 connected between the pumping unit 20 and the rectilinear protrusion 18, to dispense the fluid substance pushed by the pump unit 20 to the outside, when the pedal 19 is operated in its working position. The pumping unit 20 will now be described in detail, with particular reference to figs. 9 and 10, in which this unit is shown moved to its rest position, and in figs. 11 and 12 in which the unit is shown moved to its working position. The pump group 20 ? substantially constituted by a solid cylindrical body 27 of limited length, which is fixed on the internal surface of the flat base 9, and in which obtained a cavity? internal 28 in which a cylindrical piston 29 is housed and slidable with a limited stroke, shaped with an elongated stem 30 terminating in an end? rounded 31, in contact with a short straight folded edge 32 of a square (not shown), equipped with another short straight edge 33 fixed to the pedal 19, said piston 29 being shaped with an enlarged central protrusion 34, in sliding contact with the straight inner wall (not indicated) of the cavity? internal 28, and it also being shaped at its other end? with a terminal head 35, to which one?end? of a short reaction spring 36 housed in said cavity? internal. Between the enlarged boss 34 and the terminal head 35 ? obtained a seat (not indicated) in which ? housed a lip seal 37 which, during the sliding of the piston 29 in the cavity? internal 28, ensures the hermetic seal of the latter towards the outside, thus preventing? that the fluid substance introduced into this cavity? inside can go out towards the outside. The plunger 29 ? sliding with its shank 30 through a through hole (not shown) made at one end? in the cylindrical body 27 and with its central projection 34 and its head 35 in the cavity? internal 28, whose diameter ? greater than the diameter of the through hole in which the stem 30 slides. open of this cavity? inside 28 is hermetically closed by a rear cap 38, fixed to the cylindrical body 27, and against the internal wall of this cap 38 abuts and hooks the other end? of the reaction spring 36. In this way, when the pedal 19 is kept in its rest position (see fig. 10), the piston 29 is kept in its primitive position by the force of the spring 36 which ? relaxed and not compressed, while when the pedal 19 is pressed down and moved into its working position (see fig. 12), the flap 32 of the pedal pushes the piston 29 into the cavity? internal 28, compressing the spring 36 towards the plug 38, and when the pedal 19 is no longer? pressed downwards, the spring 36 returns to its primitive relaxed position of FIG. 10, thus pushing the piston 29 automatically into its previous rest position. The pump group 20 ? it is also provided with a first entrance 39 fixed in a through opening 40 made through the cylindrical body 27 and communicating with the cavity? internal 28 of the latter, and in which ? housed a one-way valve 41 for the inlet of the fluid substance, said first inlet being connected to its end? free with a? extremity? of the first duct 24 connected with the other end? with the container 13. The pumping unit 20 ? further provided with a second entrance 42, angularly spaced from the first entrance and separated from it, which entrance ? fixed in a corresponding through opening 43 made through the cylindrical body 27 and communicating with the cavity? internal 28 of the latter, and in which ? housed a one-way valve 44 for the outlet and delivery of the fluid substance, said second inlet being connected to its end? free with a? extremity? bottom of the second duct 26, which in its upper part? bent orthogonally (see figs. 6 and 15), so as to form a portion of horizontal duct 46 housed in the straight horizontal protrusion 18 and supported by an upper support 45, fixed in the cavity? internal 17 of the column and also supporting the remaining portion of the duct 26, said portion of duct 46 being open at its end? free, for the delivery of the fluid substance on the underlying hands of the user.

Nella posizione di riposo del pedale 19, la valvola unidirezionale 41 ? normalmente aperta e la valvola unidirezionale 44 ? normalmente chiusa, per cui la sostanza fluida contenuta nel recipiente 13 viene continuamente introdotta per gravit?, attraverso il primo condotto 24 ed il primo imbocco 39, nella cavit? interna 28 del gruppo di pompaggio 29, fino a riempire tale cavit? interna, ed in questa condizione la sostanza fluida non esce dal secondo imbocco 42 e non viene fatta circolare attraverso il secondo condotto 26, e la porzione di condotto 46, e quindi non viene erogata. In the rest position of the pedal 19, the one-way valve 41 is normally open and the one-way valve 44 ? normally closed, whereby the fluid substance contained in the container 13 is continuously introduced by gravity, through the first duct 24 and the first inlet 39, into the cavity? internal 28 of the pumping group 29, until filling this cavity? inside, and in this condition the fluid substance does not come out of the second inlet 42 and is not made to circulate through the second duct 26, and the portion of duct 46, and therefore is not dispensed.

Quando il pedale 19 viene spostato nella sua posizione di lavoro, esso aziona lo stantuffo 29, ed in questa condizione viene chiusa la valvola d?ingresso 41 ed aperta la valvola d?uscita 44, per cui mentre viene impedito l?ingresso di ulteriore sostanza fluida nella cavit? interna 28, la sostanza fluida contenuta in tale cavit? interna viene spinta lungo i due condotti 26 e 46 ed erogata verso l?esterno, con un volume di sostanza fluida erogata commisurato alla spinta esercitata dallo stantuffo 29. Al rilascio del pedale 19, la molla 36 riporta lo stantuffo 29 nella sua posizione di riposo, ed in questa condizione viene chiusa la valvola d?uscita 44 ed aperta la valvola d?ingresso 41, per cui grazie alla variazione del volume della sostanza fluida contenuta nella cavit? interna 28 ed alla gravit?, dal recipiente 13 viene introdotta ulteriore sostanza fluida nella detta cavit? interna, fino a riempire quest?ultima. When the pedal 19 is moved to its working position, it actuates the piston 29, and in this condition the inlet valve 41 is closed and the outlet valve 44 is opened, so that while the entry of further substance is prevented fluid in the cavity internal 28, the fluid substance contained in this cavity? inside is pushed along the two ducts 26 and 46 and dispensed towards the outside, with a volume of fluid substance dispensed commensurate with the thrust exerted by the piston 29. When the pedal 19 is released, the spring 36 returns the piston 29 to its rest position , and in this condition the outlet valve 44 is closed and the inlet valve 41 is opened, so that thanks to the variation of the volume of the fluid substance contained in the cavity, inside 28 and to gravity, further fluid substance is introduced from the container 13 into said cavity? internal, up to fill the latter.

Column for the distribution of fluid substances of various kinds, and in particular of sanitizing gel, soap, cream and hand washing paste, suitable for being installed in public environments (schools, hospitals, public services, etc?), and in private environments (homes, companies, offices, etc?), to dispense these fluid substances without the user's hands coming into contact with the component parts of the column itself, and with high reliability? operational, the column (5) being advantageously made of metallic materials, such as for example stainless steel, anodized aluminum, or plastic material, and being of the self-supporting type and substantially constituted by an elongated frame (6) extending in the direction vertical, characterized by the fact that said casing (6) ? formed by a first straight vertical portion (7) of parallelepiped shape or other suitable geometric shape, and internally hollow for its entire extension, and by a second straight vertical portion (8) of parallelepiped shape, of smaller dimensions than those of the first portion (7), and joined above to the latter, said first portion of carcass (7) being delimited below by a flat base (9), joined at the end? bottom of the first portion (7) and larger than the same, which is placed on the floor of the room where the column (5) is? installed, and this portion of the casing (7) being furthermore delimited at the top by a flat surface (10) in which a through opening (11) is made, which can be closed by a corresponding flat sheet (12), through which opening a container (13) for containing the fluid substance is introduced, said container (13) being rested below on an internal support (14 ) fixed in the cavity? interior (15) of the first carcass portion (7) and being provided with an upper opening which can be closed by a corresponding plug (16), and located in correspondence with the through opening (11); characterized in that said second carcass portion (8) ? made in a parallelepiped shape with smaller dimensions than those of the first portion (7) and extends vertically upwards for a given length, and it is also shaped with a cavity? internal (17) communicating with said cavity? internal part (15) and in the upper end part of said second carcass portion (8) ? centrally fixed a? extremity? of a rectilinear protrusion (18), of smaller dimensions than those of said second carcass portion and spaced from the flat sheet (12), protruding on the front of said second carcass portion of a? extension such as to coincide with the? through opening (11), from? the other end? of said protrusion (18) as the fluid substance is dispensed, so that it reaches the user?s hands, which are introduced into the space between the flat sheet (12) and the protrusion (18), in which at the part lower end of the first carcass portion (7) ? fixed in an articulated way a pedal (19), cooperating with a pumping group (20) of the fluid substance, which is internally fixed to said first carcass portion and ? which can be activated by the pressure of the user's foot, from a rest position in which this pumping group (20) is not activated, and the fluid substance is not dispensed, to a working position in which this pumping group (20) is operated and the fluid substance is delivered and, when the foot no longer presses? on the pedal (19), the latter automatically returns to its rest position, called distribution column (5) being closed at the back by a flat backrest (21), of the same size as the column and which can be fixed against the rear wall (22) of said column, so that when the backrest (21) is applied against said rear wall (22), it closes the cavities? interior of the column, and when ? required? access in these cavities? inside and in the component parts housed therein, the backrest (21) is unscrewed and removed from its closed position, and characterized by the fact that inside the distribution column (5) ? also installed is a first circulation duct (24) connected between the bottom (25) of said containment container (13) and said pumping unit (20), to introduce the relative fluid substance into the latter, and is a second conduit (26) connected between said pumping unit (20) and said rectilinear protrusion (18), to dispense the fluid substance pushed by the pumping unit (20) to the outside, when the pedal (19) is operated in its off position Work.

2. Distribution column according to claim 1, characterized in that said pumping group (20) is substantially constituted by a solid cylindrical body (27) of limited length, which is fixed on the internal surface of the flat base (9), and in which ? obtained a cavity? inside (28) in which a cylindrical piston (29) is housed and slidable with a limited stroke, shaped with an elongated stem (30) ending in an? rounded edge (31), in contact with a short straight folded edge (32) of a small square equipped with another short straight edge (33) fixed to the pedal (19), said piston (29) being shaped with an enlarged central protrusion (34 ), in sliding contact with the straight inner wall of the cavity? internal (28), and it being furthermore shaped at its other end? with a terminal head (35), to which one? of a short reaction spring (36) housed in said cavity? internal, between the enlarged projection (34) and the terminal head (35) a seat being obtained in which ? housed a lip seal (37) which, during the sliding of the piston (29) in the cavity? internal (28), ensures the hermetic seal of the latter towards the outside, thus preventing? that the fluid substance introduced into this cavity? can exit towards the outside, said piston (29) being sliding with its stem (30) through a through hole made at one end? in the cylindrical body (27) and with its contral prominence (34) and its head (35) in the cavity? internal (28), whose diameter ? greater than the diameter of the through hole in which the stem (30) slides, the end? open of this cavity? inside (28) being hermetically closed by a rear cap (38), fixed to the cylindrical body (27), and against the internal wall of this cap (38) coming into contact and hooking the other end? of the reaction spring (36), so that when the pedal (19) is kept in its rest position, the piston (29) is kept in its original position by the force of the spring (36), which ? relaxed and not compressed, while when the pedal (19) is pressed down and moved into its working position, the flap (32) of the pedal pushes the piston (29) into the cavity? internal (28), compressing the spring (36) towards the cap (38), and when the pedal (19) is no longer? pressed downwards, the spring (36) returns to its original relaxed position, thus pushing the piston (29) automatically into its previous rest position.

3. Distribution column according to claim 2, characterized in that said pumping unit (20) is also provided with a first inlet (39) fixed in a through opening (40) made through the cylindrical body (27) and communicating with the cavity? internal (28) of the latter, and in which ? housed a one-way valve (41) for the inlet of the fluid substance, said first inlet (39) being connected with its end? free with a? extremity? of the first duct (24) connected with its other end? with the container (13), the pumping unit (20) being further provided with a second inlet (42), angularly spaced from the first inlet and separated from it, which inlet ? fixed in a corresponding through opening (43) made through the cylindrical body (27) and communicating with the cavity? internal (28) of the latter, and in which ? housed a one-way valve (44) for the outlet and delivery of the fluid substance, said second inlet (42) being connected to its end? free with a? extremity? bottom of the second duct (26), which in its upper part? bent orthogonally, so as to form a portion of horizontal duct (46) housed in the straight horizontal protrusion (18) and supported by an upper support (45), fixed in the cavity? interior (17) of the column and also supporting the remaining portion of the duct (26), said duct portion (46) being open at its end? free, for the delivery of the fluid substance on the underlying hands of the user.

4. Distribution column according to claim 3, characterized in that in the rest position of the pedal (19), the one-way valve (41) is ? normally open and the one-way valve (44) ? normally closed, whereby the fluid substance contained in the container (13) is continuously introduced by gravity, through the first duct (24) and the first inlet (39), into the cavity? inside (28) of the pumping unit (29), until this cavity is filled? inside, and in this condition the fluid substance does not come out of the second inlet (42) and is not circulated through the second duct (26), and the portion of duct (46), and therefore is not dispensed, and when the pedal ( 19) is moved to its working position, it actuates the piston (29), and in this condition the inlet valve (41) is closed and the outlet valve (44) is opened, so that while the? entry of further fluid substance into the cavity? internal (28), the fluid substance contained in this cavity? inside is pushed along the two ducts (26 and 46) and dispensed outwards, with a volume of fluid dispensed commensurate with the thrust exerted by the piston (29), and with the release of the pedal (19) the spring (36) returns the piston (29) to its rest position, and in this condition the outlet valve (44) is closed and the inlet valve (41) is opened, so that thanks to the variation of the volume of the fluid contained in the cavity ? inside (28) and to gravity, further fluid substance is introduced from the container (13) into said cavity? internal, up to fill the latter.
