DESCRIPTION OF PREFERRED EMBODIMENTS

(10) FIG. 1 shows a connection device 1 for a toilet bowl 2 in a schematic manner. The connection device 1 substantially comprises a bearing element 4 and a carrier arrangement 5. The bearing element 4 can is optional and can also be omitted in other embodiments. Subsequently, the figures with the bearing element 4 are explained in greater detail.

(11) The bearing element 4 is fixedly arranged in a receiving space 3 of the toilet bowl 2 and is fixedly connected to the toilet bowl 2. Preferably, the bearing element 4 is braced, in the receiving space 3, against the inner walls of the receiving space 3.

(12) The carrier arrangement 5 comprises a first bearing point 6 in which a flushing pipe 7 is mounted, and a second bearing point 8 in which an outflow pipe 9 is mounted. Flushing water can be supplied to the toilet bowl 2 by way of the flushing pipe 7, and waste water is conducted away from the toilet bowl 2 by way of the outflow pipe 9. In the assembled state, the flushing pipe 7 is connected to a flushing water line 10 which is arranged in a positionally fixed manner on site, and is connected, on the toilet bowl side, to the flushing water inflow 11 of the toilet bowl 2. The flushing water inflow 11 is part of the toilet bowl 2. By way of the flushing water inflow 11, the flushing water is supplied from the flushing water line 10 to the toilet bowl 2. In the assembled state, the outflow pipe 9 is connected to a waste water line 12 which is arranged in a positionally fixed manner on site, and is connected, on the toilet bowl side, to a waste water outflow 13. The axial distance A between the center axis M7 of the flushing pipe 7 and the center axis M9 of the outflow pipe 9 is fixed or constant in the carrier arrangement 5. The axial distance corresponds to the axial distance between the flushing water line 10 and the waste water line 12. That is to say, the two bearing points 6, 8 are fixedly arranged on the carrier arrangement 5. Likewise, the elements arranged on site, namely the flushing water line 10 and the waste water line 12, are at a fixed distance with respect to one another. In addition, the flushing water inflow 11 and the waste water outflow 13 of the toilet bowl 2 are also at a fixed distance with respect to one another. Preferably, the axial distance A between the two bearing points 6, 8 is greater than the axial distance B between the flushing water inflow 11 which is arranged on the toilet side and the waste water outflow 13 which is arranged on the toilet side. The difference between the two axial distances A, B preferably corresponds to the maximum adjustment offset V. The axial distance C between the flushing water line 10 and the waste water line 12 substantially corresponds to the axial distance A.

(13) The carrier arrangement 5 can be fixedly connected to an on-site fastening element 21. The on-site fastening element 21 is likewise arranged in a positionally fixed manner and is at a fixed distance with respect to the flushing water line 10 and the waste water line 12.

(14) The carrier arrangement 5 and the bearing element 4, during the adjustment of the height position of the toilet bowl 2, can be displaced relative to one another in the direction of an adjustment movement E. In this case, the bearing element 4, which is fixedly connected to the toilet bowl 2, is displaced with the toilet bowl 2 relative to the positionally fixed carrier arrangement 5. This can be readily recognized in the two depictions in FIG. 1.

(15) Further, the flushing pipe 7 and the outflow pipe 9 each comprise at least one compensation portion 14, 15, with which an adjustment offset V, which results during the adjustment movement E between the carrier arrangement 5 and the bearing element 4, between the flushing pipe 7 which is mounted in the carrier arrangement and the outflow pipe 9 which is mounted in the carrier arrangement and the flushing water inflow 11 and waste water outflow 13, respectively, which are arranged on the toilet bowl side, can be compensated. Additionally or alternatively, the adjustment offset between the flushing water line 10 and waste water line 12, respectively, which are arranged in a positionally fixed manner on site, and the flushing water inflow 11 and waste water outflow 13, respectively, which are fixedly arranged on the toilet side, can be compensatable. The adjustment offset V is illustrated in FIG. 1 as a height difference between the two toilet bowls 2.

(16) In the left-hand side of FIG. 1, the toilet bowl is located at a lower position, while in the right-hand side of FIG. 1, the toilet bowl lies in a higher position. In this case, it can be readily recognized that the carrier arrangement 5, together with the flushing pipe 7, the outflow pipe 9 and the fastening element 21, have remained at their original positions, while the toilet bowl 2, together with the fastening element 4 and the flushing water inflow 11 and also the waste water outflow 13, have been displaced upward. The displacement which is produced during the height adjustment has been compensated by way of the two compensation portions 14, 15. The two compensation portions 14, 15 are illustrated schematically in FIG. 1, and the degree of compensation is illustrated by the different inclination of the corresponding lines. As a result of the change in the compensation portion 14, 15, which correspondingly compensates for the height offset, it is possible to adjust the height of the toilet bowl 2 in space in a simple manner, without needing to make amendments on site or on the toilet bowl.

(17) FIG. 2 shows an exploded illustration of the toilet bowl 2 and of the connection device 1. The connection device 1, which is illustrated deconstructed into its individual parts, lies in a receiving space 3 of the toilet bowl 2. The receiving space 3 is accessible from behind by way of an access opening 29, and the individual elements of the connection device 1 can be inserted by way of the access opening 29.

(18) FIG. 3 shows a further exploded illustration of the individual parts of the connection device 1. On the basis of said illustration, the basic construction of the embodiment of the connection device 1 shown here is now explained in greater detail.

(19) In the embodiment shown, the bearing element 4 comprises a crossmember portion 22 and two mutually spaced-apart support portions 23 which project away from the crossmember portion 22. Preferably, the crossmember portion 22 and the support portion 23 are connected-together metal profiles. At the end side, the support portions 23, in the region of their free ends 24, each have a clamping element 25. The bearing element 4 can be braced in the receiving space 3 with the clamping element 25. The crossmember portion 22 abuts at the top side in the receiving space 3 and, at the bottom side, the fastening element 4 stands, with the clamping element 25, in the interior of the receiving space 3 against the toilet bowl 2.

(20) In the preferred embodiment, the carrier arrangement 5 is of substantially two-part configuration. The carrier arrangement 5 comprises a first carrier part 17 and a second carrier part 18 which can be connected to the first carrier part 17.

(21) Here, the bearing point 6 for the flushing pipe 7 is provided by the first carrier part 17 and the second carrier part 18 together. The flushing pipe 7 is held between the two carrier parts 17, 18. The upper part of the bearing point 6 lies on the first carrier part 17 and the lower part of the bearing point lies on the second carrier part 18. Further, the bearing point 8 for the outflow pipe 9 is arranged on the second carrier part 18. As seen from the access opening 29, the first carrier part 17 lies substantially downstream of the bearing element 4 and the second carrier part 18 lies substantially upstream of the bearing element 4. The two-part configuration of the carrier arrangement 5 has the advantage that the latter can be assembled in a simpler manner on the bearing element 4 which is already assembled in the receiving space 3.

(22) The carrier arrangement 5 comprises, here on the first carrier part 17 and on the second carrier part 18, a fastening receptacle 19. A threaded element 20 can be placed in the fastening receptacle 19. With the threaded element 20, the carrier arrangement 5 can be connected to the fastening element 21 which is assembled in a positionally fixed manner on site and which is typically a threaded rod. The threaded rod 21 is illustrated schematically in FIG. claim 1. As a result of an actuation of the threaded element 20 which lies in the carrier arrangement 5, the connection device 1, together with the toilet bowl 2, can be tightened against the wall. The threaded element 20 can be actuated with a tool, which is guided to the threaded element 20 through the two access openings 36 in the toilet bowl 2. To this end, the crossmember portion also has corresponding access openings, which also bear the reference sign 36.

(23) In the embodiment shown, the threaded element 20 holds together the first carrier part 17 and the second carrier part 18. For this purpose, the threaded element 20 has a corresponding clamping portion 32, which extends through the fastening receptacle 19 on the first carrier part 17 and through the fastening receptacle 19 and second carrier part 18. In this case, the clamping portion 32 has, at the end side, a stop 37 which holds the two carrier parts 17, 18 on the clamping portion 32. The clamping portion 32 here comprises outwardly sprung tabs.

(24) In the embodiment shown, the two support portions 23 furthermore each have a longitudinal guide 26 in which the carrier arrangement 5 is mounted in a movable manner. The carrier arrangement 5 is in this case mounted such that it can be moved relative to the bearing element 4. After the adjustment of the height has been completed, the carrier arrangement 5 and the bearing element 4 can be fixedly connected to one another. The bearing element 4, with the toilet bowl 2 at the desired height, can be fixedly secured to the carrier arrangement 5 which is positionally fixed in space.

(25) Preferably, the connection between the bearing element 4 and the carrier arrangement 5 is of positively locking and/or force-fitting and/or frictionally locking type. In the embodiment shown, a positively locking variant is shown. Various latching openings 27, which are shown in FIG. 7, are arranged in the longitudinal guides 26. Latching elements 28 are arranged on the carrier arrangement 5, said latching elements being displaceable in such a way that the latching elements can be inserted into the latching openings 27 when the desired height has been adjusted. Here, in the region of the second carrier part 18, the latching elements 28 are arranged on the second carrier part 18 and can be displaced in such a way that the latching elements 28 engage into the latching opening 27.

(26) In the embodiment shown, the second carrier part 18 also has a receptacle for a guide 33. The latching element 28 is mounted in the guide 33 in a movable manner. The guide 33 further engages into a receptacle 34 on the second carrier part 18. The connection between the guide 33 of the first carrier part 17 and the receptacle 34 of the second carrier part 18 furthermore provides an improved and, in particular, stable connection between the first carrier part 17 and the second carrier part 18.

(27) The compensation portion 14 in the flushing pipe is provided by a deflecting portion 14 in the flushing pipe 7. The deflecting portion 14 here lies between a mouth portion 30 and a bearing portion 31. With the bearing portion 31, the flushing pipe 7 is mounted in the first bearing point 6 in a pivotable manner. In the direction of the flushing water inflow 11, the bearing portion 31 is adjoined by the deflecting portion 14, which is then followed by the mouth portion 30. The bearing portion 31 is connected to the flushing water line 10, and the mouth portion 30 opens into the flushing water inflow 11. The mouth portion 30 and the bearing portion 31 extend along parallel center axes. If the flushing pipe 7, in its bearing point 6, is then pivoted about the center axis, the position, in particular the height, of the mouth portion 30 changes, as a result of which the height offset can be correspondingly compensated.

(28) On account of the pivoting movement, the mouth portion 30 is moved along a curved line. The pivoting movement is illustrated in the figures with the reference sign S. Said movement leads to a transverse offset of the mouth portion 30 in the flushing water inflow 11 in the toilet bowl 2. Said transverse offset is correspondingly compensated by the seal 16. The seal 16 is an elastic, in particular a highly elastic, seal which, in the embodiment shown, has a plurality of sealing lips 35 which are in contact with the walls of the flushing water inflow 11. During the adjustment of the height, said sealing lips 35 are then deformed elastically, in accordance with their eccentricity, toward the flushing water inflow 11. The flushing pipe 7 is preferably of rigid configuration and does not comprise a flexible portion. This has the advantage that no losses in terms of flow occur as a result of an undesired deformation of the flushing pipe 7 occurring during assembly. The mouth portion 30 of the flushing pipe is also of comparatively long configuration, such that the flushing pipe 7 can protrude as deeply as possible into the mouth portion 30, as a result of which the losses in terms of flow can be correspondingly predicted.

(29) FIG. 9 shows how the flushing pipe 7 protrudes, with the mouth portion 30, into the flushing water inflow 11 and how the seal 16 is in contact, with the sealing lips 35, with the wall of the flushing water inflow 11. In addition, FIG. 9 shows that the bearing portion 31 is in contact with the flushing water line 10.

(30) The compensation portion 15 on the outflow pipe 9 is provided by a flexible deformable pipe portion. In the embodiment shown, said pipe portion is a flexible corrugated bellows, or a rubber bellows. From FIG. 4, it is readily possible to recognize how the corrugated bellows, or the rubber bellows, is changed in terms of its shape during the height adjustment. In addition, in FIG. 4, it is likewise readily possible to recognize how the flushing pipe 7 is pivoted about its center axis in the region of the first bearing point 6 during the height adjustment. The outflow pipe 9 is fixedly held in the second bearing point 8.

(31) FIG. 5 then shows further perspective views of the connection device 1, together with the toilet bowl 2, in various height positions.

(32) FIG. 6 shows a rear view of the assembled connection device 1. The carrier arrangement 5 further comprises snap-fit elements 38, which engage into a groove 39 on the carrier arrangement 5. The groove 39 is in this case oriented in the same direction as the longitudinal guides 26, and the snap-fit elements 38 can be displaced in the groove during the height adjustment. Further, FIG. 6 shows an upper shoulder 40 on the crossmember portion 22 and a lower shoulder 40 on the clamping element 25. By way of said two shoulders, the bearing element 4 can be clamped in the receiving space 3. From FIG. 8, it is readily possible to recognize that the clamping element 25 can be actuated through an access 42.

(33) FIG. 7 then shows a front view of the assembled connection device 1 in greater detail. A respective guide tab 41 is arranged laterally with respect to the compensation portion 15 of the outflow pipe 9, said guide tab preventing the compensation portion 15 from deflecting laterally with respect to the direction of movement of the height adjustment.
