Description

Die Erfindung betrifft einen Kastenkörper für einen Spülkasten gemäss Oberbegriff des Anspruchs 1.The invention relates to a cistern body for a cistern according to the preamble of claim 1.

Kastenkörper dieser Art sind allgemein bekannt. Sie werden in der Regel aus Keramik oder Kunststoff hergestellt. In den letzten Jahren ist es durch eine verbesserte Spültechnik gelungen, die für eine Spülung notwendige Wassermenge wesentlich zu vermindern. Entsprechend konnten die Kastenkörper mit kleinerem Volumen gebaut werden. Der kleinere Innenraum der Kastenkörper führte jedoch zu Schwierigkeiten bei der Unterbringung der Armaturen, also insbesondere der Einlauf- und Ablaufarmatur. Insbesondere bei Unterputzspülkästen führte dies zu einer aufwändigen und umständlicheren Montage der Einlauf- und Ablaufarmatur. Bei diesen Spülkästen müssen diese Armaturen durch eine frontseitig oder oben angeordnete Revisionsöffnung eingesetzt werden. Zudem ist bei diesen Spülkästen die Bautiefe vergleichsweise gering.Box bodies of this type are generally known. you will be usually made of ceramic or plastic. In In recent years, it has been through an improved flushing technique succeeded in the amount of water necessary for a rinse reduce significantly. Accordingly, the box bodies could be built with a smaller volume. The smaller one Interior of the box body, however, caused difficulties when accommodating the fittings, in particular the Inlet and outlet fittings. Especially with concealed cisterns this led to an elaborate and cumbersome Installation of the inlet and outlet fittings. With these cisterns these fittings must be through a front or top arranged inspection opening can be used. In addition is the depth of these cisterns is comparatively small.

Die US-A-3,860,972 offenbart einen Spülkasten mit einem Kastenkörper, in den ein Überlaufkanal integriert ist. Der Kastenkörper besteht aus einem unteren und einem oberen Teil, die mit Schnallen und Dichtungsmitteln miteinander verbunden sind. Der Überlaufkanal wird durch einen Durchgang im unteren Teil und ein Rohr im oberen Teil des Kastenkörpers gebildet. Die Herstellung dieses Kastenkörpers ist vergleichsweise aufwändig und die Verbindung zwischen den genannten beiden Teilen, insbesondere bezüglich der Dichtigkeit, problematisch.US-A-3,860,972 discloses a cistern with a Box body in which an overflow channel is integrated. The Box body consists of a lower and an upper Part that with buckles and sealants together are connected. The overflow channel is through a passage in the lower part and a tube in the upper part of the box body educated. The production of this box body is comparatively complex and the connection between the two parts mentioned, especially with regard to the Tightness, problematic.

Der Erfindung liegt die Aufgabe zugrunde, einen Kastenkörper der genannten Art zu schaffen, der kostengünstiger herstellbar und dennoch funktionssicher ist. The invention has for its object a box body to create the type mentioned, the less expensive to manufacture and yet it is reliable.

Die Aufgabe ist bei einem gattungsgemässen Kastenkörper gemäss Kennzeichen des Anspruchs 1 gelöst. Beim erfindungsgemässen Kastenkörper bildet damit die Wandung einen Teil einer Einlauf- oder Ablaufarmatur. Dieser entsprechende Funktionsteil ist dann im Kastenkörper integriert und muss dann selbstverständlich nicht mehr an dem zu montierenden Armaturteil vorhanden sein. Die Verlagerung wenigstens eines Funktionsteils nach aussen in die Wandung des Kastenkörpers ermöglicht die Herstellung von kleineren Armaturen, die entsprechend einfacher in den Kastenkörper einsetzbar sind. Nach einer Weiterbildung der Erfindung ist der in die Wandung des Kastenkörpers integrierte Funktionsteil ein Überlaufkanal. Bei der Ablaufarmatur kann dann das übliche Überlaufrohr durch einen schmalen Stab ersetzt werden. Entsprechend kann der Aussendurchmesser der Ablaufarmatur verkleinert werden. Eine schlankere Ablaufarmatur beansprucht im Innenraum des Kastenkörpers weniger Platz und lässt sich beispielsweise durch die Revisionsöffnung eines Unterputzspülkastens wesentlich einfacher montieren und auch zur Revision herausnehmen. Ebenfalls sind Einstellarbeiten an den Armaturen einfacher vorzunehmen.The task is according to a generic box body Characteristic of claim 1 solved. In the inventive The box body thus forms part of the wall Inlet or drain fitting. This corresponding functional part is then integrated in the box body and must then of course no longer on the fitting part to be assembled to be available. The relocation of at least one Functional part outwards into the wall of the box body enables the production of smaller fittings that are correspondingly easier to insert into the box body. According to a further development of the invention, it is in the wall of the box body integrated functional part an overflow channel. The usual thing can be done with the drain fitting Overflow pipe to be replaced by a narrow rod. Corresponding the outer diameter of the drain fitting can be reduced become. A slimmer drain fitting is required less space inside the box body and can be for example through the inspection opening of a concealed cistern assemble much easier and also for revision remove. Adjustments to the Fittings easier to make.

Nach einer Weiterbildung der Erfindung ist der im Kastenkörper integrierte Funktionsteil ein Einlaufkanal. Bisher war dieser Kanal üblicherweise an der Einlaufarmatur als nach unten ragendes Rohr angebracht. Die Verlagerung des Einlaufkanals in die Wandung des Kastenkörpers ermöglicht nun die Herstellung einer wesentlich kleineren und kompakteren Einlaufarmatur, die entsprechend einfacher zu montieren und herzustellen ist.According to a development of the invention, the is in the box body integrated functional part an inlet channel. So far this channel was usually on the inlet fitting as downward pipe attached. The relocation of the Inlet channel in the wall of the box body allows now the production of a much smaller and more compact Inlet fitting which is correspondingly easier to assemble and is to be manufactured.

Es hat sich gezeigt, dass für die Integration der genannten Funktionsteile und auch für andere Funktionsteile die Herstellung des Kastenkörpers durch Blasformen besonders vorteilhaft ist. Diese Funktionsteile, und insbesondere Rohre sowie Kanäle können beim Blasformen ohne weitere Verfahrensschritte hergestellt werden. Diese Funktionsteile werden vorzugsweise durch Quetschen angeformt. Dazu weisen zwei Formteile entsprechend gegeneinander gerichtete und zusammenarbeitende Quetschteile auf. Die genannten Funktionsteile sind dann fest am Kastenkörper angebracht und bilden einen integrierten Teil der Seitenwandungen und/oder des Kastenbodens. Diese Funktionsteile sind am Kastenkörper vorzugsweise angeformt und bilden somit einen Teil der Wandung. Die Herstellung des Kastenkörpers durch Blasformen ist die bevorzugte Ausführung. Denkbar sind jedoch auch andere Herstellungsverfahren. Als Funktionsteile werden hier Teile verstanden, die bisher üblicherweise Teile der Einlauf- oder Ablaufarmatur oder anderen im Kasteninnern untergebrachten Armaturen waren. Befestigungsteile sind keine solchen Funktionsteile.It has been shown that for the integration of the above Functional parts and also for other functional parts the manufacture of the box body by blow molding particularly advantageous is. These functional parts, and especially pipes and channels can be used in blow molding without further process steps getting produced. These functional parts will be preferably formed by squeezing. Point to this two molded parts facing each other accordingly cooperating squeeze parts. The functional parts mentioned are then firmly attached to the box body and form an integrated part of the side walls and / or of the box bottom. These functional parts are on the box body preferably integrally formed and thus form part of the wall. The production of the box body by blow molding is the preferred version. However, others are also conceivable Production method. As functional parts are here Understood parts that were previously usually parts of the inlet or drain fitting or other housed inside the box Fittings were. Fasteners are not such functional parts.

Die Erfindung ermöglicht die Herstellung von Kastenkörpern mit einem noch kleineren Volumen als bisher. Bei einer zu erwartenden weiteren Verbesserung der Spültechnik und damit noch kleineren Spülwassermengen als bisher lassen sich mit der Erfindung die Probleme bei der Herstellung und Montage der Spülkastenarmaturen vermeiden. Die grundsätzliche Idee der Erfindung wird somit darin gesehen, bisher an Spülkastenarmaturen und Armaturen vorgesehene Funktionsteile nach aussen in den Kastenkörper zu integrieren. Die bevorzugte Herstellung durch Blasformen ermöglicht eine besonders einfache und kostengünstige Realisierung solcher Kastenkörper.The invention enables the production of box bodies with an even smaller volume than before. With one too expected further improvement in flushing technology and thus even smaller amounts of rinse water than before can be used the invention the problems in the manufacture and assembly avoid cistern fittings. The basic idea the invention is thus seen in hitherto cistern fittings and fittings provided functional parts to integrate into the outside of the box body. The preferred Production by blow molding enables a particularly simple one and inexpensive realization of such box bodies.

Die Erfindung betrifft auch einen Spülkasten mit einem Kastenkörper sowie ein besonders geeignetes Verfahren zur Herstellung eines erfindungsgemässen Kastenkörpers.The invention also relates to a cistern with a cistern body and a particularly suitable method for Production of a box body according to the invention.

    • Die Figur 1 zeigt einen Kastenkörper 1 mit einer Wandung 2, die im wesentlichen einen rechteckigen vergleichsweise schmalen Kasten bildet. In einer Frontwandung 5 ist eine sogenannte Revisionsöffnung 7 eingearbeitet, durch die insbesondere eine Ablaufarmatur 13 (Figur 2) sowie eine Einlaufarmatur 20 (Figur 2) eingesetzt wird. Durch die Öffnung 7 können diese Armaturen auch revidiert und ausgebaut werden. Der Kastenkörper 1 ist für einen Unterputzspülkasten bestimmt und wird somit in einer Maueröffnung montiert und frontseitig abgedeckt. Vor der Revisionsöffnung 7 wird eine hier nicht gezeigte sogenannte Abdeckplatte installiert. Die Revisionsöffnung 7 kann aber auch auf der Oberseite des Kastenkörpers 1 angeordnet sein. Denkbar ist auch eine Ausführung, bei welcher der Kastenkörper 1 für einen Spülkasten bestimmt ist, der sichtbar auf einer Wandung oder auf einer WC-Schüssel montiert wird.FIG. 1 shows a box body 1 with a wall 2, which is essentially a rectangular by comparison forms a narrow box. In a front wall 5 is one so-called inspection opening 7 incorporated, through which in particular a drain fitting 13 (Figure 2) and an inlet fitting 20 (Figure 2) is used. Through the opening 7 these fittings can also be revised and expanded. The box body 1 is for a concealed cistern determined and is thus mounted in a wall opening and covered on the front. In front of the inspection opening 7 So-called cover plate not shown installed here. The inspection opening 7 can also on the top of the Box body 1 may be arranged. An execution is also conceivable, in which the body 1 for a cistern is determined, which is visible on a wall or on a toilet bowl is installed.

    Im Boden der Wandung 2 befindet sich eine Auslauföffnung 9, an der ein hier nur schematisch gezeigtes Ablaufrohr 8 angebracht ist. Das Ablaufrohr 8 kann an der Wandung 2 angeformt sein. Über der Öffnung 9 wird im Innern des Kastenkörpers 1 die Ablaufarmatur 13 in bekannter Weise befestigt. Mit einem anhebbaren Ventilkörper 14 wird die Ablauföffnung 9 verschlossen. Mittels einer hier nicht gezeigten üblichen Betätigungsvorrichtung kann der Ventilkörper 14 angehoben und damit die Öffnung 9 für den Auslauf von Spülwasser freigegeben werden.In the bottom of the wall 2 there is an outlet opening 9, to which a drain pipe 8 shown here only schematically is attached is. The drain pipe 8 can be molded onto the wall 2 his. Above the opening 9 is inside the box body 1 attached the drain fitting 13 in a known manner. With a liftable valve body 14, the drain opening 9 closed. By means of a not shown here The usual actuator can be the valve body 14 raised and thus the opening 9 for the spout be released from rinse water.

    An einer Seitenwandung 3 der Wandung 2 ist aussenseitig ein Überlaufkanal 10 angeordnet, insbesondere angeformt. Dieser Überlaufkanal 10 besitzt gemäss Figur 2 eine obere Einlauföffnung 11 mit einer Überlaufkante 11'. Der Überlaufkanal 10 erstreckt sich aussenseitig nach unten und am Boden entlang bis zum Auslaufrohr 8. Eine Mündung 12 verbindet den Überlaufkanal 10 mit diesem Ablaufrohr 8, wie die Figur 2 deutlich zeigt. Steigt im Innenraum 40 des Kastenkörpers 1 das Spülwasser beim Nachfüllen über die Überlaufkante 11', so wird ein weiteres Ansteigen des Spülwasserniveaus durch den Überlauf in den Überlaufkanal 10 verhindert. Das überlaufende Spülwasser gelangt durch den Kanal 10 in das Ablaufrohr 8 und von dort in eine WC-Schüssel oder ein Urinal. Der Überlaufkanal 10 kann gemäss den Figuren 4 und 6 etwa mittig und aussenseitig an der Seitenwandung 3 angeordnet sein. Nach einer Variante nach Figur 5 befindet sich der Überlaufkanal 10' im Bereich einer Kante des Kastenkörpers 2. Bei dieser Ausführungsvariante ist der Überlaufkanal 10 weniger vorstehend als bei der Ausführung gemäss den Figuren 2, 4 und 6. Zwischen den beiden Öffnungen 11 und 12 ist der Überlaufkanal 10 über einen vergleichsweise schmalen Steg 19 mit der Wandung 2 verbunden. Denkbar ist auch eine Ausführung, bei welcher dieser Steg 19 nicht besteht und der Überlaufkanal 10 lediglich im Bereich der Überlauföffnung 11 und der Öffnung 12 befestigt ist. Der Überlaufkanal 10 kann aber auch direkt an der Wandung 2 anliegen oder angebracht sein. Der Querschnitt des Überlaufkanals 10 bzw. 10' kann auch rund sein oder einen anderen geeigneten Querschnitt aufweisen.On a side wall 3 of the wall 2 is on the outside Overflow channel 10 arranged, in particular molded. This Overflow channel 10 has an upper inlet opening according to FIG 11 with an overflow edge 11 '. The overflow channel 10 extends downwards on the outside and along the floor to the outlet pipe 8. A mouth 12 connects the Overflow channel 10 with this drain pipe 8, as in FIG. 2 clearly shows. Rises in the interior 40 of the box body 1 the rinse water when refilling over the overflow edge 11 ', so a further increase in the rinse water level is caused by prevents the overflow into the overflow channel 10. The overflowing Flushing water gets through the channel 10 into the drain pipe 8 and from there into a toilet bowl or urinal. The overflow channel 10 can according to FIGS. 4 and 6 arranged approximately in the middle and on the outside on the side wall 3 his. According to a variant according to FIG the overflow channel 10 'in the region of an edge of the box body 2. In this variant, the overflow channel is 10 less above than in the execution according to the Figures 2, 4 and 6. Between the two openings 11 and 12th is the overflow channel 10 over a comparatively narrow Web 19 connected to the wall 2. It is also conceivable an embodiment in which this web 19 does not exist and the overflow channel 10 only in the area of the overflow opening 11 and the opening 12 is attached. The overflow channel 10 can also rest directly on the wall 2 or be appropriate. The cross section of the overflow channel 10 or 10 'can also be round or another suitable Have cross-section.

    Da der Überlaufkanal 10 ein Teil der Wandung 2 ist, kann entsprechend an der Ablaufarmatur 13 ein Überlaufrohr fehlen. Das üblicherweise im Ventilkörper 14 integrierte Überlaufrohr ist hier durch einen vergleichsweise schmalen Stab 14' ersetzt. Dieser Stab ist an seinem oberen Ende mit der hier nicht gezeigten Betätigungsvorrichtung verbunden. Der Stab 14 kann auch beweglich oder gelenkig oder durch eine Kette oder dergleichen ersetzt sein.Since the overflow channel 10 is part of the wall 2, can accordingly, an overflow pipe is missing on the drain fitting 13. The overflow pipe usually integrated in the valve body 14 is here by a comparatively narrow Rod 14 'replaced. This rod is at its top end with connected to the actuator, not shown here. The rod 14 can also be movable or articulated or through a chain or the like can be replaced.

    Die Wandung 2 besitzt gemäss Figur 2 einen Einlaufkanal 16, der gemäss Figur 4 aussenseitig in die Frontwandung 5 integriert ist. Der Einlaufkanal 16 besitzt eine obere Einlauföffnung 17 sowie eine untere Öffnung 18. Die obere Öffnung 17 ist über eine hier nicht gezeigte Leitung mit der Einlaufarmatur 20 verbunden. Beim Nachfüllen des Kastenkörpers 1 mit Spülwasser gelangt dieses Wasser vom Einlaufventil der Armatur 20 über die genannte Leitung durch die Öffnung 17 in den Kanal 16 und durch die untere Öffnung 18 in das Innere des Kastenkörpers 2. Die Einlaufarmatur 20 kann auch direkt an der Öffnung 17 angebracht sein. Die Leitung erübrigt sich dann. An der Einlaufarmatur 20 fehlt entsprechend das bei diesem sonst übliche Einlaufrohr. Ansonsten kann die Einlaufarmatur 20 wie üblich ausgebildet sein. Sie wird an eine hier nicht gezeigte Versorgungsleitung angeschlossen und besitzt ein hier nicht gezeigtes übliches Einlaufventil, das beispielsweise von einem Schwimmer reguliert wird. According to FIG. 2, the wall 2 has an inlet channel 16, 4 integrated into the front wall 5 on the outside is. The inlet channel 16 has an upper inlet opening 17 and a lower opening 18. The upper opening 17 is via a line, not shown here, with the Inlet fitting 20 connected. When refilling the box body 1 With rinse water, this water comes from the inlet valve the armature 20 via said line through the opening 17 in the channel 16 and through the lower opening 18 in the inside of the box body 2. The inlet fitting 20 can also be attached directly to the opening 17. The administration then unnecessary. The inlet fitting 20 is missing accordingly that with this otherwise common inlet pipe. Otherwise the inlet fitting 20 can be designed as usual. she is connected to a supply line, not shown here and has a common one not shown here Inlet valve, for example, regulated by a float becomes.

    An einer Schmalseite 4 des Kastenkörpers 2 ist gemäss den Figuren 2 und 4 ein weiterer Kanal 21 angeformt. Dieser besitzt eine obere Öffnung 21, die den Kanal 21 mit dem Kasteninnern verbindet. Eine untere Öffnung 22 führt nach aussen. In den Kanal 21 ist eine flexible Leitung 23 eingeführt, die das Einlaufventil 20 insbesondere mit einer hier nicht gezeigten WC-/Duschvorrichtung verbindet. Das aus der Öffnung 22 herausragende Ende der Leitung 23 ist dazu beispielsweise mit einer Überwurfmutter 24 versehen. Der Kanal 21 bildet hier somit einen Installationskanal für die Leitung 23. Auch dieser Installationskanal 24 bildet einen integrierten Teil der Wandung 2.On a narrow side 4 of the box body 2 is according to the Figures 2 and 4 formed another channel 21. This owns an upper opening 21 that the channel 21 with the box interior combines. A lower opening 22 leads Outside. A flexible line 23 is introduced into the channel 21, which the inlet valve 20 in particular with one here connects toilet / shower device, not shown. That from the Opening 22 protruding end of line 23 is for example provided with a union nut 24. The channel 21 thus forms an installation duct for the line here 23. This installation channel 24 also forms an integrated one Part of the wall 2.

    Bei einem erfindungsgemässen Kastenkörper 1 ist wenigstens einer der Kanäle 10, 16 und 21 realisiert. Es können selbstverständlich auch zwei oder alle drei dieser Kanäle 10, 16 und 21 im Kastenkörper 2 integriert sein. Denkbar ist auch eine Ausführung, bei welcher beispielsweise der Einlaufkanal 16 wie bisher üblich am Einlaufventil 20 angebracht ist. Bei der Ausführung nach Figur 1 ist lediglich der Überlaufkanal 10 in die Wandung 2 integriert.In the case of a box body 1 according to the invention, at least one of the channels 10, 16 and 21 realized. It can of course two or all three of these channels 10, 16 and 21 can be integrated in the box body 2. Conceivable is also an embodiment in which, for example, the Inlet channel 16 attached to the inlet valve 20 as usual is. In the embodiment of Figure 1 is only the overflow channel 10 integrated into the wall 2.

    Die Herstellung des Kastenkörpers 1 kann beispielsweise durch Blasformen erfolgen. Dies wird nachfolgend anhand der Figur 7 erläutert. Das Blasformen von Kastenkörpern 1 ist an sich bekannt. Bei einem erfindungsgemässen Verfahren besitzen zwei Formhälften 26 und 27 zwei nach innen ragende Teile 28, zwischen denen ein vergleichsweise schmaler Zwischenraum besteht. Beim Schliessen der beiden Formteile 26 und 27 wird von einem Innenraum 31 ein kanalförmiger Raum 30 abgetrennt. Zwischen den beiden Teilen 28 wird die hier nicht gezeigte Wandung des Schlauches gequetscht und bildet den in Figur 6 gezeigten Steg 19. Entlang dieses Steges wird die Wandung durch einen Schmelzprozess verbunden. Nach dem Abkühlen der Form 24 und dem Trennen der beiden Formteile 26 und 27 ist der Kastenkörper 1 mit dem integrierten Überlaufkanal 10 und gegebenenfalls mit weiteren integrierten Funktionsteilen realisiert. Weitere Arbeiten für den Kanal 10 sind nicht erforderlich. Der Kastenkörper 1 ist damit mit einem Zusatznutzen versehen und übernimmt wenigstens eine bei einem Kastenkörper bisher nicht übliche Funktion.The production of the box body 1 can, for example by blow molding. This is explained below using the Figure 7 explains. The blow molding of box bodies 1 is known per se. In a method according to the invention two mold halves 26 and 27 two inwardly projecting Parts 28, between which a comparatively narrow space consists. When the two molded parts 26 are closed and 27 of an interior 31 becomes a channel Room 30 separated. Between the two parts 28 Squeezed wall of the hose, not shown here forms the web 19 shown in Figure 6. Along this The wall is connected by a melting process. After cooling mold 24 and separating the two Molded parts 26 and 27 is the box body 1 with the integrated Overflow channel 10 and possibly with others integrated functional parts. More work for channel 10 are not required. The box body 1 is thus provided with an additional benefit and takes over at least one not previously common in a box body Function.
