DETAILED DESCRIPTION OF THE INVENTION

(10) FIG. 1 shows a perspective view of a water closet 1 comprising a toilet seat set 2 consisting of a lid element 3 and a seat element 4. The lid element 3 and seat element 4 together form the toilet seat set 2, wherein the lid element and seat element 4 are supported so that they can rotate relative to each other. The water closet 1 also includes a toilet bowl 5 and a douche device 6 with a housing 7.

(11) FIG. 1 shows the water closet 1 in the completely assembled state, in which the housing 7 of the douche device 6 and the toilet seat set 2 are mounted on the toilet bowl 5.

(12) FIG. 2 shows a perspective view of the toilet bowl 5 of the water closet 1 of FIG. 1, wherein all of the add-on parts such as the toilet seat set 2 and the douche device 6 have been removed. On the top of the toilet bowl 5, two openings 22 are shown, one of which is provided to accept a water line connector 17, the other an electrical line connector 16. FIG. 2 also shows two openings 23, which are on the inside with respect to the openings 22 and into each of which a mounting screw 9 can engage to fasten the mounting plate 8 to the toilet bowl 5. This is shown in detail in FIG. 3.

(13) FIG. 3 shows a perspective view of the water closet 1 of FIG. 1, before the housing 7 and the toilet seat set 2 are installed. In FIG. 3, a mounting plate 8 is shown, which is fastened to the toilet bowl 5 by mounting screws 9. The mounting screws 9 pass through mounting openings 10 in the mounting plate 8 and into the openings 23 in the top of the toilet bowl 5. There, the mounting screws 9 can be fastened by means of pins or nuts. Support spacers 11 are also provided, which are arranged to extend over the mounting openings 10. By means of the support spacers 11, the mounting plate 8 can be adjusted within a certain range relative to the mounting openings 10.

(14) FIG. 3 also shows that the mounting plate 8 includes two openings 12, each of which is configured to accept a fastening element 13. The openings 12 are also internally threaded, whereas the fastening elements 13 include an external thread 24 at the appropriate end.

(15) At their free end, i.e., the end opposite the external thread 24, the fastening elements 13 include a recess 14, which serves to mount the toilet seat set 2, which will be discussed again further below.

(16) The mounting plate 8 also includes two projections 15, which serve to mount the housing 7 of the douche device 6, which will be described in conjunction with FIG. 4. In addition, an electrical line connector 16 and a water line connector 17 are arranged on the toilet bowl 5. The electrical line connector 16 and the water line connector 17 pass through their assigned openings 22 in the toilet bowl 5, shown in greater detail in FIG. 2, and are guided through these openings 22 to the rear wall of the toilet bowl 5, so that, in the installed state of the water closet 1, no cables or lines can be seen. FIG. 3 also shows retaining plates 26, each of which includes an opening, which partially surrounds its assigned line connector 16, 17. The retaining plates 26 prevent the line connectors 16, 17 from sliding out through the openings 22 into the toilet bowl 5 during assembly. After the line connectors 16, 17 have been attached to the bottom of the housing 7, the retaining plates 26 can be pulled off to one side, and the cable or line connectors 16, 17 are then pushed back as appropriate into the toilet bowl.

(17) FIG. 4 shows the water closet 1 of FIG. 1 during the mounting of the toilet seat set 2, i.e., prior to the adjustment of the mounting plate 8. For this purpose, the toilet seat set 2 includes two second connecting means 18, which include a geometry complementary to the recesses 14 in the fastening elements 13 and which therefore make it possible for the toilet seat set 2 to lock onto the fastening elements 13, i.e., to the mounting plate 8 and thus to the toilet bowl 5. The toilet seat set 2 is latched by means of the two connecting means 18, which preferably the shafts of the rotational axis of the toilet seat set 2, i.e., of the support of the lid element 3 on the seat element 4.

(18) The toilet seat set 2 with its connecting means 18 is latched in place by setting it down from above onto the fastening elements 13. For this purpose, the fastening elements 13 are introduced into the connecting means 18, and an edge (not shown) provided in the connecting means 18, for example, is brought into engagement with the recess 14, which produces the desired latching effect. For this purpose, the connecting means 18 are configured as an opening, into which the edge projects laterally. The edge includes a shape complementary to the recess 14 and, when engaged in the recess 14, it prevents the fastening element 13 from being pulled out of the corresponding connecting means 18. The edge, furthermore, is connected to an actuating element in such a way that, when the actuating element is actuated, the edge is pushed sideways out of the opening in the connecting means 18. The edge can, for example, be configured as a through-opening in a spring-loaded piece of sheet metal connected to the actuating element. The through-opening includes a diameter which is larger than that of the actuating element 13. When the actuating element is actuated, the opening is moved coaxially to the opening in the connecting element. As a result, the latching connection is disengaged, and the toilet seat set can be pulled away from the fastening element 13 or from the fastening elements 13. As long as the actuating element remains unactuated, the edge remains latched in the recess 14 under spring tension.

(19) Then, after the toilet seat set has been set in place, the toilet seat set 2 and the mounting plate 8 attached to it can be adjusted on the toilet bowl 5, and after the adjustment has been completed, it can be secured by means of the mounting screws 9. After the adjustment, the toilet seat set 2 can be removed again by disengaging the connection between the connecting means 18 and the fastening elements 13. This is achieved, according to this exemplary embodiment, by means of the actuating element, which disengages the edge from the recess 14. It is also possible to overcome the latching resistance by applying a certain force and pulling the toilet seat set 2 from the fastening elements 13. The fastening elements 13, furthermore, can also be removed again, so that the housing 7 of the douche device 6 can be mounted on the toilet bowl 5.

(20) FIG. 5 shows a detailed view of part of the water closet 1 of FIG. 1 in the area of the mounting plate 8 during the mounting of the housing 7 of the douche device 6. To simplify the drawings, the water line connector 17 and the electrical line connector 16 are not illustrated, and only part of the housing 7 and toilet bowl 5 are shown. FIG. 5 shows the situation which is present when the housing 7, with the recesses 19 complementary to the projections 15 of the mounting plate 8, is being mounted on the mounting plate 8 by pushing it on, for example. In the assembled state, the projections 15 engage in the recesses 19 and thus hold the housing 7 of the douche device 6 in place on the mounting plate 8, which in turn is mounted on the toilet bowl 5. Of course, it is also possible that the projections could be executed on the housing 7 and the recesses on the mounting plate 8.

(21) The mounting plate 8 includes tabs 27, one of which surrounds each of the openings 12; these tabs can have any other desired shape, however.

(22) FIG. 6 shows a perspective view of part of the water closet 1 of FIG. 1, in which the douche device 6, i.e., the housing 7 of the douche device 6, is being installed on the toilet bowl 5, i.e., on the mounting plate 8. FIG. 6 shows the mounting step which follows the step illustrated in FIG. 5. After the housing 7 has been pushed onto the projections 15 on the mounting plate 8, the housing 7 is still not completely mounted on the toilet bowl 5, however, because the housing can be detached again at any time by pushing it backwards, for when that is done, the projections 15 are pulled out of the complementary recesses 19, and the housing 7 can be lifted off the toilet bowl 5.

(23) To complete the mounting of the housing 7 on the toilet bowl 5, therefore, the fastening elements 13 are screwed into the openings 12 provided for them in the mounting plate 8. The openings 12 are not visible here, because they are covered by the housing 7, which completely covers the mounting plate 8. The openings 20 in the housing 7, however, which are coaxial to the openings 12, can be easily seen. The fastening means 13 are guided through the openings 20 and then screwed into the openings 12 in the mounting plate 8. It is shown here that in each case a washer 21 is provided for each of the fastening elements 13, which improves the ability to tighten the fastening element 13 or fastening elements 13 against the housing 7. The washers 21 serve as support spacers for the fastening elements 13. For this purpose, the inside diameter of the washers 21 is smaller than that of the section of the fastening elements 13 which adjoins the external thread 24. In addition to the washers 21, washers 25 are also shown. The diameter of the hole in the washers 25 is larger than that of the washers 21. The washers 25 serve as damping stops for the connecting means 18 when the toilet seat set 2 is set down onto the fastening elements 13.

(24) FIG. 7 shows the water closet 1 of FIG. 1 in the mounting step following the one shown in FIG. 6. Here the housing 7 of the douche device 6 is held in place on the toilet bowl 5, i.e., on the mounting plate 8, which is arranged underneath the housing 7, by means of the fastening elements 13. In the mounting step shown in FIG. 7, the toilet seat set 2 is attached to the fastening elements 13 and thus to the toilet bowl 5 by way of the mounting plate 8. To achieve this, the fastening elements 13 are introduced into the connecting means 18 of the toilet seat set 2; that is, the toilet seat set 2 with its connecting means 18 is set down from above onto the fastening elements 13, wherein, upon introduction of the fastening elements 13 into the connecting means 18, a latching connection is produced as a result of the internal structure of the connecting means 18. In the interior of each of the connecting elements 18, a projection is provided, which engages in the recess 14 in the corresponding fastening element 13.

(25) Upon completion of the mounting step shown in FIG. 7, the water closet 1 is in the state shown in FIG. 1. FIG. 8 shows an exploded view of the water closet 1 of FIG. 1, wherein, for the sake of clarity, the line connectors 16, 17 are not shown.

(26) While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
