Further features and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, which show a preferred, but not limiting, embodiment of the invention. In detail: Fig. 1 shows a perspective view from the side and from above of a complete device according to the invention, Fig. 2 a perspective view from above of a valve device included in Fig. 1, Fig. 3 a perspective view from below of the device according to Fig. 2, Fig. 4 a diametrical axial section of a device according to frg 2 and 3 according to the section line A - A in fig. 5 and Fig. 5 a top view of the device according to one of Figs. 2 - 4.

I tig 1 betecknas hela tappningsanordningen med 1. Den kan innefatta t ex en regelliknande pelare 2 av något slag, t ex bestående av plast och/eller metall och/eller trä, och är avsedd att i t ex vertikalt läge fästas vid en vägg eller liknande (ej visad) eller alternativt vara självbärande eller -stående. Pe- laren e dyl 2 uppbär med sin övre ände en konsol 3, på vilken är anordnad en ventilanordning 4 en- ligt uppﬁniiingen. Vid den nedre änden av pelaren e dyl 2 är ledbart infast via en pivotbult 5 ena änden av en i rät vinkel från pelaren utskjutande hävstångsliknande fotpedal 6, nära vars ledbart infästa ände via ett fästorgan 7 är fastsatt den nedre änden av en wire 8, som sträcker sig parallellt relativt pelaren, och vars övre ände är fastsatt vid nämnda ventilanordning 4.In Fig. 1, the entire tapping device is denoted by 1. It may comprise, for example, a rule-like pillar 2 of some kind, for example consisting of plastic and / or metal and / or wood, and is intended to be attached to a wall or the like in a vertical position, for example. (not shown) or alternatively be self-supporting or standing. The pillar or the like 2 carries with its upper end a bracket 3, on which a valve device 4 according to the arrangement is arranged. At the lower end of the pillar e dyl 2 is articulated fastened via a pivot bolt 5 one end of a lever-like foot pedal 6 projecting at right angles from the pillar, near whose articulated fastening end via a fastening member 7 the lower end of a wire 8 is fixed, which extends parallel to the pillar, and its upper end is attached to said valve device 4.

Ventilanordningens 4 stomme 9 utgöres av två mot varandra öppna cirkulärcylindriska skålformade halvor 10 och 11 innefattande var sin .runtomgående vägg 12 resp 13 »och botten 14 resp 15. Den ena halvan, topphalvan 10, har en centralt axiellt genomgående inloppsöppning 16, som sträcker sig ge- nom bottnen 14 och omges innanför väggen 12 av en i ett stycke med denna tillverkad central stos 17, som sträcker sig från bottnen ända fram till ungefärligen det plan, som rymmer väggens 12 fria ändsida. Företrädesvis ligger stosens fria ändsida några mm innanför nämnda plan. I den inom om- rådet för bottnen 12 lämpligen som en gängad borrning utförda öppningen 16 är utifrån inskruvad en t ex med utanpå bottnen anliggande sexkantﬂäns 18 försedd anslutningsstos 19, på vilken kan fästas på i och för sig känt sätt t ex en flexibel vattentillförselslang (ej visad).The body 9 of the valve device 4 consists of two open-circular circular-cylindrical cup-shaped halves 10 and 11, each comprising a circumferential wall 12 and 13, respectively, and a bottom 14 and 15, respectively. through the bottom 14 and is surrounded inside the wall 12 by a central piece 17 made in one piece with this, which extends from the bottom all the way to approximately the plane which houses the free end side of the wall 12. Preferably, the free end side of the socket is a few mm inside said plane. Screwed into the opening 16, preferably in the area of the bottom 12, designed as a threaded bore, is for example screwed in, for example, a hexagon 19 connected to the outside of the bottom and provided with a hexagon socket 18, to which a flexible water supply hose (in a manner known per se) can be attached. not shown).

Genom halvans 10 vägg sträcker sig i t ex radialled en genomgående utloppsöppning 20 utförd i synnerhet som en gängad borrning, i vilken utifrån är inskruvad en anslutningsstos e dyl 21. Denna stos kan ha samma utformning som stosen 19, vilket underlättar och förbilligar tillverkning och lagerhållning. Eljest kan stosen 21 vara någon form av utloppspip eller kan till denna stos anslutas en slang, ett rör eller liknande. Stosen 21 eller till denna ev anslutnaiorgan behöver ej förses med avstängningsmedel. 10 15 20 25 30 35 518 659 u o n o f u o n a o q ø ~ n n u Den andra halvans 11 botten 15 är försedd med en central axiellt genomgående styröppning 22, som på bottnens insida kan fortsätta ett stycke genom en kortare styrstos 23. I styröppningen är inifrån insatt en till en ventilkropp 24 hörande ventilspindel 25, som nära det genom väggens 13 fria ändsi- da gående planet är ansluten till en tallrik 26 med en lämpligen svagt konvex fri ändyta 27 och en diameter, som är ungefårligen lika stor som stosens 17 ytterdiameter. Mellan tallriken 26 och styr- stosen 23 eller bottnen 15 omges spindeln 25 av en förspänd, t ex skruvformig tryckíjäder 28, som strävar efter att pressa tallriken mot den fria änden av stosen 17, vilken ände är anordnad som ven- tilsäte 29. Spindelns 25 andra ände skjuter ut genom bottnen 15 och är där försedd med ett fästorgan 30, t ex en ring 31 med en gängad bult 32, som är inskruvad i en gängad borrning 33 i spindelns yt- tre ände. Vid fastorganet är fastsatt den övre änden av nämnda wire 8. Spindeln 25 tillåter genom spel relativt styrstosen eller' på annat sätt, t ex profilering, en ventilering av det av halvan 11 inne- slutna hålrummet 34 med atmosfären.Extending through the wall of the half 10 in a radial direction, for example, is a continuous outlet opening 20 made in particular as a threaded bore, in which a connecting socket or the like 21 is screwed in from the outside. Otherwise, the nozzle 21 may be some form of outlet spout or a hose, a pipe or the like may be connected to this nozzle. The socket 21 or to this possible connecting member does not need to be provided with shut-off means. The bottom 15 of the second half 11 is provided with a central axially continuous guide opening 22, which on the inside of the bottom can continue for a distance through a shorter guide socket 23. In the guide opening a one to one is inserted from the inside. valve body 25 belonging to valve body 24, which near the free end face plane passing through the wall 13 is connected to a plate 26 with a suitably slightly convex free end surface 27 and a diameter which is approximately equal to the outer diameter of the socket 17. Between the plate 26 and the guide socket 23 or the bottom 15, the spindle 25 is surrounded by a prestressed, eg helical compression spring 28, which strives to press the plate against the free end of the socket 17, which end is arranged as a valve seat 29. The spindle 25 the other end projects through the bottom 15 and is provided there with a fastening member 30, for example a ring 31 with a threaded bolt 32, which is screwed into a threaded bore 33 in the outer end of the spindle. Attached to the fixed member is the upper end of said wire 8. The spindle 25 allows by means of play relative to the guide socket or in another way, for example profiling, a ventilation of the cavity 34 enclosed by the half 11 with the atmosphere.

Mellan väggamas 12, 13 fria ändytor är med sitt runtomgående kantområde fastklämt ett väggarnas ytterkontur följande membran 35, som således kommer att ligga mellan ventilsätet 29 och tallriken 26. T ex gienom axiella hål 36 genom den övre bottnen 14 och väggen 13 sig sträckande skruvar (ej visade) är förankrade i den nedre halvans vägg och pressar så membranet fast, varigenom det nedre hålrummet, förutom nämnda ventilering, blir hermetiskt tillslutet och skilt från motsvarande övre hålrum 37.Between the free end surfaces of the walls 12, 13 is clamped with its circumferential edge area an outer contour of the walls following the membrane 35, which will thus lie between the valve seat 29 and the plate 26. For example through axial holes 36 through the upper bottom 14 and the wall 13 extending screws ( are not anchored in the wall of the lower half and thus presses the membrane firmly, whereby the lower cavity, in addition to said ventilation, is hermetically closed and separated from the corresponding upper cavity 37.

En sådan tappanordning installerad enligt ﬁg 1 fungerar på följande sätt: Pedalen 6 är lämpligen anordnad fällbar och/eller snabbmonterbar vid pelaren 2. Dito gäller för konsolen 3 vid pelaren och for ventilanordningen 4 vid konsolen. Allt detta för att erhålla optimala lagrings-, transport-, monterings- och utbytbarhetsegenskaper. Till inloppsstosen 19 ansluts en vat- tenledning, varvid vattentrycket är av underordnad betydelse. Man skall kunna använda anordnin- gen enligt uppfinningen både vid normala och extremt låga tryckförhållanden. Hos en så installerad anordning behöver användaren ej röra vid ventilanordningen i allmänhet och utloppet 21 i synner- het. På så sätt förebyggs föroreningar och smittspridning långtgående, vilket har stor betydelse, t ex vid katastroﬁnsatser. Önskas uttag av vatten, så trampar användaren på pedalen 6, som verkar som en enarmad hävstång, där avståndet mellan svängningsaxeln 5 och fästorganet 7 lämpligen bara är en bråkdel av avståndet mellan fästorganet 7 och den fria änden av pedalen. På så sätt kan med en ganska liten kraftinsats utövas ett relativt stort dragmoment på wiren 8, vilket innebär, att fjädern 28 kan väljas relativt kraf- tig och härigenom en tillförlitlig stängning av inloppsöppningen 16 erhålles, eﬂersom den mot 10 15 20 25 30 35 518 650 4 bottnen 15 eller styrstosen 23 sig stödjande fjädern 28 pressar tallriken 26 och därmed det ﬂexibla, särskilt gummielastiska, membranet 35 under viss deformering mot sätet 29 mot verkan av vatten- trycket i inloppet. Vid nedtryckt pedal dras således tallriken 26 mot verkan av fjädern 28 nedåt och membranet friger sätet 29, så att vatten kan strömma in i hålrummet 37 och därifrån ut genom ut- loppsöppningen 20. Släpper man sedan pedalen, så återför fjädern omedelbart tallriken och mem- branet till stängningsläge, vilket innebär, att man aldrig kan glömma att stänga av vattenflödet.Such a tapping device installed according to ﬁ g 1 works in the following way: The pedal 6 is suitably arranged foldable and / or quick-mountable at the column 2. This applies to the bracket 3 at the column and to the valve device 4 at the bracket. All this to obtain optimal storage, transport, assembly and interchangeability properties. A water line is connected to the inlet nozzle 19, whereby the water pressure is of secondary importance. It must be possible to use the device according to the invention in both normal and extremely low pressure conditions. In such a device installed, the user does not have to touch the valve device in general and the outlet 21 in particular. In this way, pollution and the spread of infection are far-reaching, which is of great importance, for example in the event of disasters. If withdrawal of water is desired, the user steps on the pedal 6, which acts as a single-armed lever, where the distance between the pivot shaft 5 and the fastening means 7 is suitably only a fraction of the distance between the fastening means 7 and the free end of the pedal. In this way, with a rather small force input, a relatively large tensile moment can be exerted on the wire 8, which means that the spring 28 can be selected relatively strongly and thereby a reliable closing of the inlet opening 16 is obtained, since it 650 4 the bottom 15 or the guide socket 23 supporting the spring 28 presses the plate 26 and thus the visible, in particular rubber-elastic, diaphragm 35 under some deformation against the seat 29 against the action of the water pressure in the inlet. When the pedal is depressed, the plate 26 is thus pulled downwards against the action of the spring 28 and the diaphragm releases the seat 29, so that water can flow into the cavity 37 and from there out through the outlet opening 20. If the pedal is then released, the spring immediately returns the plate and memory. the branch to the closed position, which means that you can never forget to turn off the water flow.

Härigenom uppnås en automatisk sparverkan.This achieves an automatic saving effect.

När tallriken förs nedåt, följer också membranet med ett stycke, så att hålrummet 34 minskar i vo- lym. Härvid sker en tryckutjämning genom styröppningen 22 enligt tidigare beskrivning. Man kan dock även tänka sig, att sådan tryckutjämning uteblir, nämligen då spindeln 25 är tätt inpassad i styröppningen. På så sätt hålles membranet även vid nedåtförd tallrik emot sätet 29 eller i varje fall nära sätet, så att en viss möjligen önskad stryp- eller dämpnings- eller tryckregleringseffekt på det utströmmande vattnet erhålles.When the plate is moved downwards, the membrane also follows with a piece, so that the cavity 34 decreases in volume. In this case, a pressure equalization takes place through the guide opening 22 as previously described. However, it is also conceivable that such pressure equalization does not occur, namely when the spindle 25 is tightly fitted in the guide opening. In this way, the membrane is held even when the plate is lowered against the seat 29 or in any case close to the seat, so that a certain possibly desired throttling or damping or pressure control effect on the outflowing water is obtained.

Som synes, är alla delar av anordningen enligt uppfinningen enkla och lätt monterbara samt utbyt- bara. Man kan även tänka sig utforma de båda ventilanordningshalvorna identiskt lika, varvid borr- ningar 36 är anordnade växelvis i båda halvorna och de båda stosarna 17 och 23 har bragts på en gemensam nämnare, t ex med kortare utförande och med ett genomböjt membranläge i utgångsläget som följd. På så sätt kan ytterligare besparingar göras.As can be seen, all parts of the device according to the invention are simple and easily mountable and replaceable. It is also conceivable to design the two valve device halves identically, wherein bores 36 are arranged alternately in both halves and the two sockets 17 and 23 have been brought on a common denominator, e.g. sequence. In this way, additional savings can be made.

Uppfinningen är inte begränsad till ovan beskrivna och på bifogade ritningar visade utförande utan kan modifieras och kompletteras på godtyckligt sätt inom ramen för uppfinningstanken och följande patentkrav.The invention is not limited to the embodiment described above and shown in the accompanying drawings, but can be modified and supplemented in any way within the scope of the inventive concept and the following claims.
