The invention relates to a sanitary article, in particular a flush toilet, with a standing sanitary basin, in particular a toilet bowl, and with a plastic outlet pipe which can be connected thereto in a sealing manner and forms a siphon.

From DE 81 38 259 U1 a siphon, in particular for flush toilets, is known which has at least one part which at least partially defines the flow path and which can be moved between a first position in which the flow path has the rise required for a complete odor trap and a second position in which the rise of the flow path is at least reduced, wherein any mechanical seals present between the movable part and the adjoining, fixed parts which define the flow path in front of and behind the movable part remain in contact with the sealing surfaces assigned to them and wherein the movable part is coupled to an actuating device which moves it into its second position at the start of the medium drainage process and back to its first position before the liquid supply ends. The movable part which at least partially forms the siphon loop is formed by a flexible, hose-like hollow body.

From DE 92 02 878 U1 an electronic water-saving water closet is known which has a movable, flexible pipe which serves as a siphon to prevent odours when the water closet is not in use and which is straightened and emptied by lowering one end when flushing.

US 5,257,422 A discloses a drain connection for a sanitary article designed as a hanging urinal basin, in which the basin is attached to a wall by means of screw bolts. The drain of the basin is connected to the drain pipe of the installation via a siphon, in which straight and relatively dimensionally stable sections and sections that are flexible relative to these are connected to one another.

DE 36 42 176 C1 discloses a device for connecting and supporting a sanitary facility on the floor, which consists of a base plate on which a cuboid outlet part containing at least one line is arranged, the outlet part having at least one inlet opening and one outlet opening and the outlet part supporting the sanitary facility. The base plate and/or the outlet part can consist of a plastic, in which the line is molded. The line running inside the outlet part can have an odor trap. The front toilet bowl is placed on the outlet part and can be specially connected to it, e.g. by gluing.

The object of the present invention is to propose a standing sanitary article which can be invisibly attached to the sanitary room floor using simple means.

This object is achieved according to the invention in a sanitary article of the type mentioned at the outset, for example, in that the outlet pipe is designed as a self-supporting rigid or essentially rigid fastening part for the sanitary basin

and can be attached to or in the drain of the sanitary basin on the one hand and to the sanitary room floor on the other hand.

This ensures that the sanitary article, which itself stands directly on the sanitary floor and is supported by it, and therefore does not require a special support part, is secured against moving on the sanitary room floor without this being noticeable from the outside. There is therefore no need for any special means of anchoring the sanitary article to the sanitary room floor.

This aim can be achieved in a particularly simple manner by connecting the outlet pipe at its end facing the sanitary basin to the drain of the sanitary basin via a sealing sleeve, while the outlet pipe at its end facing away from the sanitary basin has a plate that is wider than the rest of the pipe cross-section for fastening to the sanitary room floor. The outlet pipe and plate or similar fastening area can be designed as one piece. However, it is also possible for the outlet pipe to protrude into the plate as a separate part.

For the assembly and for the drainage function of the outlet pipe, it is particularly advantageous if the outlet pipe is connected to the drain of the sanitary basin with a pipe section that is essentially horizontal in the installation position, while the outlet pipe has, at its end facing away from the sanitary basin, a pipe section that is essentially vertical in the installation position, which is possibly connected to the plate or projects into it.

To save material, the plate can be designed like a bowl with a recess that is open to the sanitary room floor.

According to a further feature of the invention, the bottom of the plate can have an insertion opening for receiving the preferably vertical pipe section of the outlet pipe, which vertical section then opens into the drainage.

To ensure the necessary inherent stability and support of the outlet pipe, the plate can be equipped with support ribs and/or webs running around its peripheral edge.

Furthermore, it can be advantageous if the plate has hole- and/or slot-like fastening and/or adjustment openings, which facilitate precise assembly.

Further aims, advantages and possible applications of the invention emerge from the following description of embodiments with reference to the drawing. All described and/or illustrated features, either individually or in any combination, form the subject matter of the present invention, regardless of their summary in individual claims or their reference back to one another.

The sanitary articles 1 shown in the figures are a standing flush toilet with a sanitary basin 2 designed in particular as a toilet bowl. However, the invention can also be advantageous for other sanitary articles, for example for standing bidets or urinals.

An outlet pipe 4 is connected to the sanitary basin 2 in a sealed manner with the aid of a sealing sleeve 6, which forms a siphon 3 as an odor trap. The outlet pipe 4 is made of plastic and is therefore, in contrast to corresponding ceramic parts of a conventional type, easy and inexpensive to manufacture in any shape, for example by gluing two pipe halves together at separating surfaces running along the length of the pipe. In the exemplary embodiment shown, the outlet pipe 4 is secured by inserting a pipe section 8 which is essentially horizontal in the installed position to a correspondingly horizontal drain 5 of the sanitary basin 2.

At the end facing away from the sanitary basin 2, the outlet pipe 4 projects with a pipe section 9 which is essentially vertical in the installed position into a central insertion opening 12 of the base 11 of a plate 7 which is also made of plastic and which, in order to save material, has a recess 10 on the base and is supported by support ribs or webs 13 on the sanitary room floor B, on which the sanitary basin 2 also stands. According to the illustration in Fig. 2, the support ribs or webs 13 run on the outer peripheral edge of the plate 7, and also at a distance around the central insertion opening 12 for the outlet pipe 4 and around the fastening openings 14, so that they ensure a low material consumption for stiffening the plate 7. The plate 7 has, as can also be seen from Fig. 2, a small outer slot-like adjustment opening 14'. On its way from the drain 5 of the

The connection between the sanitary basin 2 and the vertical pipe section 9, which opens into the drainage, is formed by the outlet pipe 4, usually a siphon 3 which serves as an odor trap and is formed by a drain bend.

In this way, the sanitary basin 2 standing on the sanitary room floor B is reliably secured against lateral displacement, in that the outlet pipe 4, which can be produced inexpensively, itself serves as a fastening part due to its rigidity.
