Description

Oppfinnelsen vedrører en røranordning av elastisk materiale for avtrede-skåler, bestående av en på skålens avløps-stuss skyvbar, tilnærmet sylindrisk rørmuffe, et i avløpsledningen innsettbar, tilnærmet sylindrisk rørstykke med en annen diameter og et begge delene forbindende mellomstykke, samt en fremgangsmåte for fremstilling av denne røranordning. The invention relates to a pipe device made of elastic material for drain bowls, consisting of a nearly cylindrical pipe sleeve that can be pushed onto the bowl's drain connection, an approximately cylindrical pipe piece with a different diameter that can be inserted into the drain line and an intermediate piece connecting both parts, as well as a method for manufacturing of this pipe arrangement.

Ved slike røranordninger er det for avtetning mellom røranordningen og skålens avløpsstuss utformet flere tverrgående, elastiske, ringformede tetningsribber på innsiden av rørmuffen, hvorav minst to slike tetningsribber må ligge tettende an mot avløpsstussen. For å oppnå dette må avløpsstussen ha en betrakte-lig lengde. In the case of such pipe devices, several transverse, elastic, ring-shaped sealing ribs are designed on the inside of the pipe sleeve for sealing between the pipe device and the bowl's drain connection, of which at least two such sealing ribs must lie tightly against the drain connection. To achieve this, the drain connector must have a considerable length.

Ofte har skålene, som f.eks. de såkalte Euro-skåler, bare korte avløpsstusser, slik at en skikkelig avtetning ved hjelp av tetningsribbene ofte ikke finner sted. Often the bowls, such as the so-called Euro bowls, only short drain connections, so that a proper sealing with the help of the sealing ribs often does not take place.

Dessuten blir skålene ofte ved oppsetting ikkeIn addition, the bowls often do not turn when set up

nøye sentrert mot avløpsledningen med avløpsstussene, slik at røranordningen, ved påskyvningen på avløpsstussen og/eller ved innskyvningen i avløpsledningen blir kantet, slik at man heller ikke i dette tilfellet får skikkelig tetning. carefully centered against the drain line with the drain spigots, so that the pipe device, when pushed onto the drain spigot and/or when pushed into the drain line, is edged, so that you do not get a proper seal in this case either.

Hensikten med oppfinnelsen er å utforme en rør-anordning av den innledningsvis nevnte type på en slik måte at de nevnte ulemper unngås. The purpose of the invention is to design a pipe device of the type mentioned at the outset in such a way that the aforementioned disadvantages are avoided.

Ifølge oppfinnelsen oppnår man dette ved at det i rørmuffen er anordnet en bare med muffekanten forbundet, men for-øvrig løs, på avløpsstussen skyvbar sylindrisk rørhylse, og at rørmuffen på sin innerside har minst en ringformet ribbe som i det minste strekker seg nesten til rørhylsen og danner en elastisk avstøtning for rørhylsen, og ved at mellomstykket går utover fra rørstykket til rørmuffen med en lit an vinkel i forhold ti.l et plan According to the invention, this is achieved by arranging in the pipe sleeve a cylindrical pipe sleeve that is only connected to the edge of the sleeve, but is otherwise loose, that can be pushed onto the drain spigot, and that the pipe sleeve has at least one ring-shaped rib on its inner side that at least extends almost to the pipe sleeve and forms an elastic repulsion for the pipe sleeve, and by the intermediate piece going outwards from the pipe piece to the pipe socket at a slight angle in relation to a plane

loddrett på lengdeaksen til røranordning.perpendicular to the longitudinal axis of the pipe assembly.

Ved å skyve den av den ringformede ribbe, ev. de ringformede ribber avstøttede rørhylse opp på skålens avløpsstuss, oppnås en sikker avtetning mellom røranordningen og avløpsstussen. Mellom rørhylsen og rørmuffen er det luftkamre som øker fleksi-biliteten og gir en optimal avtetning også ved en ujevn og delvis oval form på avløpsstussen, henholdsvis ved en til. utløpsledningen unøyaktig innrettet avløpsstuss. By pushing it off the ring-shaped rib, possibly the ring-shaped ribs supported pipe sleeve up on the bowl's drain connection, a secure seal is achieved between the pipe device and the drain connection. Between the pipe sleeve and the pipe sleeve there are air chambers that increase flexibility and provide an optimal seal even with an uneven and partially oval shape of the drain connector, respectively with another. the outlet pipe is not accurately aligned with the drain connector.

Mellomstykket hviler på gulvet i røranordningens monterte stilling og dekker det rundt avløpsledningen liggende gulvparti, slik at det ikke blir stilt store krav ved klargjøring av dette gulvpartiet. Videre kan det ikke trenge smuss inn mellom mellomstykket og gulvet. The intermediate piece rests on the floor in the installed position of the pipe device and covers the floor section lying around the drainage line, so that no great demands are made when preparing this floor section. Furthermore, no dirt can penetrate between the intermediate piece and the floor.

Ved en gunstig utførelse av røranordningen ifølge oppfinnelsen er hylsen utført helt glatt innvendig. Ved dette oppnås en sugende virkning av hylsen på avløpsstussen, som bedrer avtetningen mot avløpsstussen vesentlig, hvilken avtetning opprett-holdes selv ved vibrasjoner i gulvet. In a favorable embodiment of the pipe device according to the invention, the sleeve is made completely smooth inside. This achieves a suction effect of the sleeve on the drain spigot, which significantly improves the seal against the drain spigot, which seal is maintained even with vibrations in the floor.

Videre kan hylsen strekke seg minst nesten inn i forlengelsen til rørstykket og fortsette nesten til rørstykket. Furthermore, the sleeve may extend at least almost into the extension of the pipe piece and continue almost to the pipe piece.

På denne måten bevirkes et rett gjennomløp gjennom røranordningen, noe som både fremmer gjennomstrømningen og hindrer at det oppstår hvirvler. In this way, a straight passage through the pipe arrangement is effected, which both promotes the flow and prevents eddies from occurring.

Når røranordningen er montert, slutter hylsen seg til rørstykket. Derved hindres at fekalier kan trenge seg inn i luftkamrene. When the pipe assembly is assembled, the sleeve joins the pipe piece. This prevents faeces from entering the air chambers.

Oppfinnelsen vedrører også en fremgangsmåte for fremstilling av den ovenfor nevnte røranordning. The invention also relates to a method for producing the above-mentioned pipe device.

Denne fremgangsmåten blir ifølge oppfinnelsenkarakterisert vedat røranordningen sprøytestøpes i en matrise som består av en todelt yttermantel og en kjerne, ved hjelp av hvilken matrise det tiveiebringes en bunn i enden av det for innskyvning i avløpsledningen beregnede rørstykke, som har mindre diameter enn rørmuffen , og rørhylsen fremstilles som en innsnevret forlengelse av rørmuffen, idet etter sprøytestøpningen den todelte yttermantel åpnes og det ennå varme emne oppblåses med luft fra den åpne ende helt til det for rørhylsen bestemte innsnevrede rørstykke kan skyves over det for dannelsen av rørmuffen benyttede, tykkere kjernestykke, hvoretter bunnen fjernes og rørhylsen slåes innover. According to the invention, this method is characterized by the fact that the pipe device is injection molded in a matrix consisting of a two-part outer jacket and a core, with the help of which matrix a bottom is provided at the end of the pipe piece intended for insertion into the drainage line, which has a smaller diameter than the pipe sleeve, and the pipe sleeve is produced as a narrowed extension of the pipe socket, since after the injection molding the two-part outer jacket is opened and the still warm workpiece is inflated with air from the open end until the narrowed pipe piece determined for the pipe sleeve can be pushed over the thicker core piece used to form the pipe socket, after which the bottom is removed and the pipe sleeve is turned inwards.

Oppfinnelsen skal beskrives nærmere under henvisning til tegningen som viser et utførelseseksempel av røranordningen ifølge oppfinnelsen. Fig. 1 viser et frontriss av en utførelse av rør-anordningen ifølge oppfinnelsen, med strekpunktert antydning av rørhylsens forløp før den brettes inn i rørmuffen. Fig. 2 viser et lengdesnitt av røranordningen i fig. 1. The invention shall be described in more detail with reference to the drawing which shows an exemplary embodiment of the pipe device according to the invention. Fig. 1 shows a front view of an embodiment of the pipe device according to the invention, with a dash-dotted indication of the course of the pipe sleeve before it is folded into the pipe sleeve. Fig. 2 shows a longitudinal section of the pipe arrangement in fig. 1.

Den på tegningen viste røranordning tjener til å knytte en avtrede-skål sammen med en avløpsledning 1. Røranord-ningen er av et elastisk materiale, f.eks. plast. Røranordningen består av en omtrent sylindrisk rørmuffe 2 som over et mellomstykke 3 er forbundet med et omtrent sylindrisk rørstykke 4 som har en mindre diameter enn rørmuffen 2. Rørmuffen 2 har på sin innside flere ringformed ribber 5 som alle har samme lengde og skrår i den fra rørstykket 4 vendte retning. Rørstykket 4 har tetningsribber 6 på yttersiden. The pipe arrangement shown in the drawing serves to connect a drainage bowl together with a drain line 1. The pipe arrangement is made of an elastic material, e.g. plastic. The pipe arrangement consists of a roughly cylindrical pipe sleeve 2 which is connected via an intermediate piece 3 to a roughly cylindrical pipe piece 4 which has a smaller diameter than the pipe sleeve 2. The pipe sleeve 2 has on its inside several annular ribs 5 which all have the same length and slope in it from pipe piece 4 facing direction. The pipe piece 4 has sealing ribs 6 on the outside.

En sylindrisk rørhylse 7 går inn i rørmuffen 2.A cylindrical pipe sleeve 7 goes into the pipe sleeve 2.

Den sylindriske rørhylsen 7 er fremstilt i ett stykke med rørmuffen 2 og er forbundet med overkanten av rørmuffen 2, mens den forøvrig er bevegbar. Den løse hylsen 7 er utført helt glatt innvendig, slik"at den suger seg fast når den blir skjøvet over avløpsstussen til en avtrede-skål, hvorved det frembringes en særlig virkningsfull tetning mellom hylsen 7 og avløpsstussen 8. The cylindrical pipe sleeve 7 is produced in one piece with the pipe sleeve 2 and is connected to the upper edge of the pipe sleeve 2, while it is otherwise movable. The loose sleeve 7 is made completely smooth on the inside, so that it sticks when it is pushed over the drain connection to a drainage bowl, whereby a particularly effective seal is produced between the sleeve 7 and the drain connection 8.

Mellomstykket 3 strekker seg utover fra rørstykketThe intermediate piece 3 extends outwards from the pipe piece

4 til rørmuffen 2 med en spiss vinkel i forhold til et plan på lengdeaksen til røranordningen og hviler i montert tilstand på gulvet, hvorved mellomstykket 3 danner en ringformet tildekning av gulvet rundt avløpsledningen. 4 to the pipe sleeve 2 at an acute angle in relation to a plane on the longitudinal axis of the pipe device and rests in the assembled state on the floor, whereby the intermediate piece 3 forms an annular covering of the floor around the drain line.

Rørhylsen 7 går minst nesten inn i forlengelsen av rørstykket 4 og nesten til rørstykket 4. I røranordningens monterte tilstand slutter hylsen 7 seg altså også til rørstykket 4. The pipe sleeve 7 goes at least almost into the extension of the pipe piece 4 and almost to the pipe piece 4. In the assembled state of the pipe device, the sleeve 7 also joins the pipe piece 4.

De ringformede ribber 5 strekker seg minst nesten til rørhylsen 7 og danner en elastisk avstøtning for rørhylsen 7 når denne er blitt skjøvet på skålens avløpsstuss. Rørstykket 4 skyves inn i avløpsledningen 1, hvorved tetningsribbene 6 sørger for en virksom avtetning. The ring-shaped ribs 5 extend at least almost to the pipe sleeve 7 and form an elastic repulsion for the pipe sleeve 7 when this has been pushed onto the bowl's drain connection. The pipe piece 4 is pushed into the drain line 1, whereby the sealing ribs 6 provide an effective seal.

I montert tilstand dannes luftfylte kamre av de ringfomede ribber 5 mellom rørmuffen 2 og rørhylsen 7. Derved oppnås en særlig stor fleksibilitet for rørhylsen 7, og det oppstår en ytterst virkningsfull avtetning mellom rørhylsen 7 og avløpsstussen 8. In the assembled state, air-filled chambers are formed by the ring-shaped ribs 5 between the pipe sleeve 2 and the pipe sleeve 7. Thereby, a particularly great flexibility is achieved for the pipe sleeve 7, and an extremely effective seal is created between the pipe sleeve 7 and the drain connection 8.

Fortrinnsvis blir røranordningen sprøytestøpe i en matrise. Denne matrisen er oppbygd av en todelt ytre mantel og en fast kjerne. Matrisen er slik utformet at det dannes en bunn i røranordningen på rørstykkets 4 frie ende og at rørhylsen 7 dannes som en innsnevret rørende på rørmuffen 2. (Vist strekpunktert i fig. 1) . Preferably, the pipe device is injection molded in a matrix. This matrix is made up of a two-part outer mantle and a solid core. The matrix is designed in such a way that a bottom is formed in the tube assembly on the free end of the tube piece 4 and that the tube sleeve 7 is formed as a narrowed tube end on the tube sleeve 2. (Shown in dotted line in Fig. 1).

Når sprøytestøpingen er ferdig, blir den todelte ytre mantel i matrisen åpnet, og emnet blåses opp med luft som innføres gjennom den åpne ende mens materialet ennå er varmt ogmeget bøyelig. Så snart den av hylsen 7 dannede innsnevrede rør-ende skyves over den med større diameter utførte kjerne for rørmuffen 2, blir røranordningen trykket vekk fra kjernen. Etter at bunnen er fjernet og hylsen 7 er slått innover (som vist i fig. 2), er røranordningen ferdig. When injection molding is complete, the two-part outer shell in the die is opened, and the blank is inflated with air introduced through the open end while the material is still hot and very pliable. As soon as the narrowed pipe end formed by the sleeve 7 is pushed over the larger diameter core for the pipe sleeve 2, the pipe device is pushed away from the core. After the bottom has been removed and the sleeve 7 has been turned inward (as shown in Fig. 2), the pipe assembly is complete.
