Abstract

The present invention relates to an outlet device for washbasins or similar, having a valve upper part (5), which is to be mounted above the washbasin and is closable by means of a valve stopper (7), and a substantially pot-shaped valve lower part (1), which is assigned to the valve upper part (5) and is to be mounted on the underside of the washbasin and which has a laterally branching connection piece in which is mounted the ball of an eccentric rod (9), upon whose actuation the valve stopper (7) can lift. According to the invention, the outlet device is characterised in that the cylindrical pipe socket (13) of the valve lower part (1) receives a cylindrical part (17a) of a plastic insert (17) and the cylindrical pipe socket (13) has, on one side in the pipe wall, a downwardly open aperture (21), through which a bearing bush (3), moulded laterally on the plastic insert (17), for supporting the ball (10) of the eccentric rod (9), extends radially outwards. Since the surface working of the laterally moulded-on bearing bush (3) can be dispensed with, the manufacture of the pot-shaped valve lower part (1) is considerably more efficient. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Ablaufgarnitur für Waschtische oder dergleichen mit einem oberhalb des Waschtischs zu montierenden Ventiloberteil, das mittels eines Ventilstopfens verschließbar ist und einem dem Ventiloberteil zugeordneten, an der Unterseite des Waschtischs zu montierenden im wesentlichen topfförmigen Ventilunterteil mit einem seitlich abzweigenden Stutzen, in dem die Kugel einer Exzenterstange gelagert ist, bei deren Betätigung der Ventilstopfen anhebbar ist.The present invention relates to a drain fitting for washbasins or the like with a valve upper part to be mounted above the washbasin, which can be closed by means of a valve plug, and an essentially pot-shaped valve lower part associated with the valve upper part and to be mounted on the underside of the washbasin, with a branch branching off to the side, in which the ball of an eccentric rod is mounted, the valve plug can be raised when actuated.

Ablaufgarnituren für Waschtische dieses Typs sich aus dem Stand der Technik bekannt. Bei diesen wird das topfförmige Ventilunterteil einschließlich des seitlich abzweigenden Stutzens aus Metall gefertigt. Nach der Fertigung des rohen Ventilunterteils aus Metall erfolgt die Oberflächenbearbeitung mit mehreren zum Teil aufwendigen Arbeitsgängen wie schleifen, polieren, verchromen etc.. Bei diesen topfförmigen Ventilunterteilen ist aufgrund der durch den angeformten Seitenstutzen für die Exzenterstange gebildeten Geometrie die maschinelle Oberflächenbearbeitung schwierig.Drain fittings for washstands of this type are known from the prior art. In these, the cup-shaped valve lower part including the branch branching off to the side is made of metal. After the production of the raw valve lower part from metal, the surface processing takes place with several sometimes complex work steps such as grinding, polishing, chrome plating etc. With these cup-shaped valve lower parts, due to the The molded side connection for the eccentric rod geometry made the machining of the surface difficult.

Die Aufgabe der vorliegenden Erfindung besteht demnach darin, eine Ablaufgarnitur für Waschtische der eingangs genannten Art zur Verfügung zu stellen, deren Herstellung mit geringerem fertigungstechnischen Aufwand möglich ist und folglich auch eine kostengünstigere Herstellung ermöglicht.The object of the present invention is therefore to provide a waste set for washstands of the type mentioned at the outset, the production of which is possible with less manufacturing outlay and consequently also enables more cost-effective production.

Die Lösung dieser Aufgabe liefert eine Ablaufgarnitur für Waschtische oder dergleichen mit den kennzeichnenden Merkmalen des Patentanspruchs 1.The solution to this problem is provided by a drain fitting for wash basins or the like with the characterizing features of patent claim 1.

Erfindungsgemäß wird das Ventilunterteil im wesentlichen zweiteilig ausgebildet, wobei das topfförmige Ventilunterteil mit dem zylindrischen Rohrstutzen weiterhin aus Metall besteht und verchromt wird, jedoch der angeformte seitliche Rohrstutzen für die Lagerung der Exzenterstange an diesem Metallteil entfällt. Statt dessen ist ein Kunststoffeinsatzteil vorgesehen, das in den zylindrischen Rohrstutzen des Metallteils von unten her eingeschoben wird und eine seitliche angeformte Lagerbuchse ebenfalls aus Kunststoff für die Lagerung der Exzenterstange aufweist. Das äußere topfförmige Metallteil weist dabei eine nach unten offene etwa U-förmige Ausnehmung für die angeformte Lagerbuchse des Kunststoffeinsatzteils auf, so daß das Einsatzteil aus Kunststoff von unten her eingeschoben werden kann. Die Oberflächenbearbeitung der seitlich angeformten Lagerbuchse kann somit entfallen. Die Herstellung des topfförmigen Ventilunterteils mit seinem nun im wesentlichen zylindrischen Rohrstutzen und dessen Oberflächenbearbeitung ist nun wesentlich einfacher.According to the invention, the valve lower part is essentially formed in two parts, the cup-shaped valve lower part with the cylindrical pipe socket still consisting of metal and being chrome-plated, but the molded-on lateral pipe socket for storing the eccentric rod on this metal part is omitted. Instead, a plastic insert is provided, which is inserted into the cylindrical pipe socket of the metal part from below and has a molded bearing bush on the side, also made of plastic, for mounting the eccentric rod. The outer cup-shaped metal part has a downwardly open, approximately U-shaped recess for the molded bearing bush of the plastic insert, so that the plastic insert can be inserted from below. The surface treatment of the laterally formed bearing bush can thus be omitted. The production of the cup-shaped valve lower part with its now essentially cylindrical pipe socket and its surface processing is now much easier.

Vorzugsweise weist das zylindrische Einsatzteil aus Kunststoff endseitig einen radial nach außen weisenden Ringflansch auf, der beim Einpressen des Einsatzteils in das topfförmige Ventilunterteil als Anschlag dient.The cylindrical insert part made of plastic preferably has a radially outward-pointing ring flange at the end, which serves as a stop when the insert part is pressed into the cup-shaped valve lower part.

Das Ventil besteht aus einem Ventiloberteil 5, das auf der Oberseite eines Waschtisches oder dergleichen montiert wird, sowie dem korrespondierenden Ventilunterteil 1, das an der Unterseite des Waschtisches montiert wird. Zwischen Ventilunterteil 1 und dem Waschtisch ist wie üblich eine Dichtung 2 angeordnet, die in einer Ringnut an der Oberseite des Ventilunterteils gehalten ist. Diese Ringnut 11 befindet sich in einem Flansch 12 des Ventilunterteils 1 an den sich axial ein im wesentlichen zylindrischer Rohrstutzen 13 des Ventilunterteils anschließt.The valve consists of an upper valve part 5, which is mounted on the top of a washstand or the like, and the corresponding lower valve part 1, which is mounted on the underside of the washbasin. As usual, a seal 2 is arranged between the lower valve part 1 and the washstand, which is held in an annular groove on the upper side of the lower valve part. This annular groove 11 is located in a flange 12 of the lower valve part 1 to which an essentially cylindrical pipe socket 13 of the lower valve part is axially connected.

Das Ventiloberteil ist wie üblich mit Durchbrechungen versehen, durch die das Wasser abläuft und wird mittels des Ventilstopfens 7 verschlossen. Der Schaft 14 des Ventilstopfens ist in eine Führungshülse 6 axial einsteckbar, wobei diese Führungshülse im unteren Bereich mit einem Außengewinde 15 ausgestattet ist. Dieses Außengewinde 15 der Führungshülse 6 ist wiederum in ein Innengewinde einer Gewindebüchse 4 einschraubbar. Diese Gewindebüchse 4 sitzt fest in einem inneren ringförmigen Abschnitt 16 eines Kunststoffeinsatzteils 17. Dieses Kunststoffeinsatzteil 17 besteht erfindungsgemäß aus dem inneren Ring 16, von dem sich nach außen hin radiale Stege 18 erstrecken, die die Verbindung zwischen dem inneren Ring 16 und einem äußeren zu dem inneren Ring konzentrischen zylindrischen Teil des Einsatzteils 17 herstellen. Dieser zylindrische Teil 17a des Einsatzteils 17 wird von dem Rohrstutzen 13 des Ventilunterteils 1 aufgenommen, wobei die Länge des zylindrischen Teils 17a dem Rohrstutzen 13 im wesentlichen entspricht, jedoch endseitig ein radial nach außen weisender Ringflansch 19 angeformt ist, der ein axiales Verschieben des Kunststoffeinsatzteils verhindert. Seitlich ist an dem erfindungsgemäßen Kunststoffeinsatzteil 17 eine Lagerbuchse 3 angeformt, die als Lager für eine Kugel 10 der Exzenterstange 9 dient, mittels derer der Ventilstopfen 7 axial verschoben werden kann. Der Rohrstutzen 13 des Ventilunterteils weist an einer Seite eine nach unten hin offene etwa U-förmige Ausnehmung 21 auf, die in ihrer Breite der Breite der Lagerbuchse 3 entspricht und durch die sich die Lagerbuchse 3 radial nach außen hin erstreckt. Bei der Montage wird das Kunststoffeinsatzteil 17 von unten her in den Rohrstutzen 13 des Ventilunterteils eingeschoben, bis die Lagerbuchse 3 am oberen Ende der Ausnehmung 21 anliegt und der Ringflansch 19 am unteren Ende des Rohrstutzens 13 zur Anlage kommt, wobei die Maße so gewählt sind, daß das Kunststoffeinsatzteil vom Rohrstutzen (13) des Ventilunterteils unter Preßsitz aufgenommen wird. Als Führung für die Exzenterstange 9 dient in der Lagerbuchse 3 ein sich zur Ventilseite hin in der Höhe konisch erweiternder Führungsschlitz 20, der in seiner Breite dem Durchmesser der Exzenterstange 9 entspricht. Durch die erfindungsgemäße Verwendung des Kunststoffeinsatzteils 17 mit angeformter Lagerbuchse 3 aus Kunststoff wird die Herstellung des Ventilunterteils fertigungstechnisch wesentlich vereinfacht.As usual, the valve upper part is provided with openings through which the water runs off and is closed by means of the valve plug 7. The stem 14 of the valve plug can be axially inserted into a guide sleeve 6, this guide sleeve being provided with an external thread 15 in the lower region. This external thread 15 of the guide sleeve 6 can in turn be screwed into an internal thread of a threaded bushing 4. This threaded bushing 4 is firmly seated in an inner annular section 16 of a plastic insert part 17. This plastic insert part 17 according to the invention consists of the inner ring 16, from which radial webs 18 extend outwards, which form the connection between the inner ring 16 and an outer one produce inner ring concentric cylindrical part of the insert 17. This cylindrical part 17a of the insert part 17 is from the Pipe socket 13 of the lower valve part 1 is added, the length of the cylindrical part 17a essentially corresponding to the pipe socket 13, but a radially outwardly pointing annular flange 19 is formed on the end, which prevents axial displacement of the plastic insert part. On the side of the plastic insert 17 according to the invention, a bearing bush 3 is formed, which serves as a bearing for a ball 10 of the eccentric rod 9, by means of which the valve plug 7 can be axially displaced. The pipe socket 13 of the lower valve part has on one side a downwardly open approximately U-shaped recess 21 which corresponds in width to the width of the bearing bush 3 and through which the bearing bush 3 extends radially outwards. During assembly, the plastic insert 17 is inserted from below into the pipe socket 13 of the lower valve part until the bearing bush 3 bears against the upper end of the recess 21 and the ring flange 19 comes into contact with the lower end of the pipe socket 13, the dimensions being chosen so that the plastic insert is received by the pipe socket (13) of the valve base under a press fit. A guide slot 20 in the bearing bush 3 serves as a guide for the eccentric rod 9 and its width widens conically towards the valve side, the width of which corresponds to the diameter of the eccentric rod 9. The inventive use of the plastic insert 17 with molded plastic bearing bush 3 simplifies the manufacture of the valve lower part in terms of production technology.
