DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(17) FIG. 1 shows a sanitary fitting which, in its entirety, is marked with reference sign 1.

(18) The sanitary fitting 1 has a fitting body 2 and a hand lever 3.

(19) An outlet mouthpiece 5 is arranged in a fixed arm 4.

(20) A cold-water hose 6 and a warm-water hose 7 are introduced from below into the fitting body 2.

(21) The amount and the mixing ratio of warm water to cold water at the outlet mouthpiece 5 can be adjusted by way of the hand lever 3.

(22) To this end, a sanitary fixture 8 according to the invention, which is shown and described in more detail in FIGS. 4 to 8, is inserted into the fitting body 2 of the sanitary fitting 1.

(23) The sanitary fixture 8 has a base plate 9 in which a first receptacle 10 (cf. FIG. 4) for a cold-water hose end piece 11 is configured.

(24) The cold-water hose 6 can thus be introduced into the first receptacle 10.

(25) The base plate 9 has a second receptacle 12 into which a warm-water hose end piece 13 of the warm-water hose 7 can be introduced.

(26) The receptacles 10, 12 are configured as holes or other cylindrical openings.

(27) In the use position, a connector assembly 14 in the form of a planar connector surface is configured on the upper side of the sanitary fixture 8.

(28) The connector assembly 14 is disposed and configured such that a single-lever mixing cartridge 15 can be attached in a tight manner.

(29) A connector piece 16 is pivotably arranged on the base plate 9. The connector piece 16 has a continuous inner duct 17 (see FIGS. 5 and 6) which, at a first end 18 of the connector piece 16, opens out to the connector assembly 14 in a manner yet to be described in more detail.

(30) At a second end 19, the inner duct 17 opens out into a hose connector 20.

(31) FIG. 12 shows the connector piece 16 separate from the other components.

(32) It can be seen that the inner duct 17 is guided at an acute angle between the first end 18 and the second end 19.

(33) On the connector piece 16, a plug 21 is configured in an extension of the first end 18. The plug 21 is executed in a slotted manner and has a latching cam 22. In the use position, the plug 21 can be inserted into a plug receptacle 23 of the base plate, where it latches by way of the latching cam 22 with the base plate 9.

(34) The plug receptacle 23 thus forms a pivot bearing of the connector piece 16.

(35) The pivot axis of this pivot bearing is aligned parallel to the longitudinal axis of the sanitary fixture 8, which runs from top to bottom in FIG. 1.

(36) This is achieved in that the plug receptacle 23 is aligned parallel to this longitudinal axis.

(37) An adapter piece 24 is inserted between the base plate 9 and the single-lever mixing cartridge 15.

(38) On a first side 25, the lower side, this adapter piece 24 has a base-plate receptacle 26.

(39) The base-plate receptacle 26 is configured in a complementary manner to the upper side 27 of the base plate 9, such that the shape of the base-plate receptacle 26 matches the shape of the upper side 27.

(40) The connector assembly 14 which has already been mentioned is configured on a second side 28, on the upper side of the adapter piece 24.

(41) The single-lever mixing cartridge 15 can thus be attached in a tight manner to the second side 28.

(42) Projections 29 which engage in corresponding recesses 30 on the upper side 27 of the base plate 9 are configured on the first side 25, in order to prevent unintentional rotation of the adapter piece 24 in relation to the base plate 9.

(43) In a connector region 31 containing the first end 18 of the inner duct 17, the connector piece 16 is connected by way of a plug-in connection to a connector-piece receptacle 32 of the adapter piece 24.

(44) The connector region 31 and the connector-piece receptacle 32 form a pivot bearing.

(45) The plug 21 and the connector region 31 are coaxially aligned in relation to one another, such that the plug 21 with the plug receptacle 23 and the connector region 31 with the connector-piece receptacle 32 define the pivot bearing of the connector piece 16.

(46) It can be seen in FIG. 4 that a hose receptacle 33 for the cold-water hose end piece 11 and a hose receptacle 34 for the warm-water hose end piece 13 are configured in the adapter piece.

(47) It can furthermore be seen in FIG. 13 that the cold-water hose end piece 11 and the warm-water hose end piece 13 are pushed through their respective receptacles 10, 12 in the base plate 9.

(48) Subsequently, to safeguard against dropping out, a securing plate 35 is inserted transversely to the insertion direction of the hose end pieces 11, 13 into the base plate 9.

(49) From behind, this securing plate 35 engages with annular projections 36 on the hose end pieces 11, 13.

(50) It can be seen in FIGS. 9 and 10 that a connection duct of the first type 37 is routed in the interior of the adapter piece 24 from the connector-piece receptacle 32 to the connector assembly 14.

(51) In the use position, the connector piece 16 is connected to the single-lever mixing cartridge 15 via this connection duct of the first type 37.

(52) It can be seen in FIGS. 7 and 8 that the hose receptacles 33, 34 are in each case routed via a connection duct of the second type 38 to the connector assembly 14.

(53) The connection ducts 37, 38 are in each case configured in the interior of the adapter piece 16 and run obliquely in relation to the longitudinal axis of the sanitary fixture 8.

(54) Here, the connection duct of the first type 37 is routed between the connection ducts 38 and is cross-wise to them.

(55) Thus, the exit port of the single-lever mixing cartridge 15 is routed past the entry ports of the single-lever mixing cartridge 15, such that the connector piece 16 can be arranged on that side of the sanitary fixture 8 that faces the outlet mouthpiece 5.

(56) In the exemplary embodiment described, the hose connector 20 is configured as a hose nipple or an olive.

(57) A connection hose 39, on the free end of which the outlet mouthpiece 5 is fastened, is pushed onto the hose connector 20.

(58) In further exemplary embodiments, the hose connector 20 may also be configured as a recess, into which a connection hose, which, on its other hose end, is connected to the outlet mouthpiece, is plugged.

(59) A wedge-shaped clearance 40 is configured on the base plate 9 and on the adapter piece. The clearance 40 delimits the available pivot angle for the connector piece 16.

(60) A non-circular anti-rotation device 41 in the form of a flattening is also configured on the base plate 9. This anti-rotation device 41 will be described in more detail in the context of FIGS. 2 and 3.

(61) FIG. 2 and FIG. 3 show a further exemplary embodiment of a sanitary fitting 1 according to the invention. Components and functional units which are identical and/or similar in terms of construction and/or function to the preceding exemplary embodiment are marked with the same reference signs and are not specifically described once again. The previous statements thus correspondingly apply.

(62) The sanitary fitting 1 according to FIG. 2 and FIG. 3 differs from the previously described exemplary embodiment in that the arm 4 is configured as a pivot arm. To this end, a stationary pipe 42, about which the pivot arm 4 can be pivoted, is arranged in the interior of the sanitary fitting 1.

(63) The pivoting range which can be attained is limited in a manner which is known per se.

(64) The base plate 9 is inserted into an opening 43 which has a non-circular contour. By way of the anti-rotation device 41, the contour of the base plate 9 is adapted to match the opening 43. The anti-rotation device 41, in the exemplary embodiment, is configured as a flattening. In other exemplary embodiments, also projections or recesses are configured in order to provide a non-circular contour as an anti-rotation device 41.

(65) The base plate 9 thus cannot rotate in the stationary opening 43. As a result, the entire construction on the base plate 9 remains stationary when the pivot arm 4 is pivoted. Only the connector piece 16 follows the pivoting movement.

(66) In the exemplary embodiments described, the base plate 9 and the adapter piece 16 are made of plastic, whereas the securing plate 35 is made of metal.

(67) FIGS. 17 and 18 show an inner-hose arrangement 44 according to the invention for a sanitary fitting 1 which has a sanitary fixture 8 and a flexible connection hose 39.

(68) The connection hose 39 is releasably connected to a connector flange 45 for the outlet mouthpiece 5 and to the connector piece 16.

(69) During assembly, the connector flange 45 and the outlet mouthpiece 5 are placed in an outlet opening 46 of the arm 4.

(70) The maximum outer dimension of the outlet mouthpiece 5 and thus the unobstructed width of the outlet opening 46 here are adapted to the maximum outer dimension of the connector piece 16, such that the connector piece 16 can be inserted through the outlet opening 46.

(71) In order to have available sufficient freedom of movement, the connection hose 39 has a plurality of axial portions 47 which are folded in a bellows-like manner. By way of these axial portions 47, the connection hose, if and when required, can be reversibly varied in length and can be kinked.

(72) A common feature of the described exemplary embodiments is that the sanitary fitting 1 has a single-lever mixing cartridge 15, a first receptacle 10 for a cold-water hose end piece 11 and a second receptacle 12 for a warm-water hose end piece 13 and an outlet mouthpiece 5. The outlet mouthpiece 5 here is connected to the single-lever mixing cartridge 15 via a connection piece 16 by a flexible connection hose 39.

(73) Mention has yet to be made that one seal ring 52 is in each case inserted into the hose receptacles 33, 34 and into the connector-piece receptacle 32, cf. FIG. 4.

(74) FIGS. 11 to 16 show a first assembly sequence for an inner-hose arrangement 44 according to the invention, in the event that the outlet opening 46 is too narrow for the connector piece 16.

(75) First, the connection hose 39, using a flexible threading aid 48, is guided through the outlet opening 46 into the fitting body 2 and from there out through the mixer opening 49, FIG. 11.

(76) Subsequently, the connector piece 16 is fastened on the connection hose 39 by way of a hose clamp 50, FIG. 12.

(77) In a next step, the base plate 9 is inserted through the mixer opening 49 into the opening 43. Now, the connector piece 16 is inserted into the mixer opening 49.

(78) In this process, the connection hose 39 is reversibly kinked at the provided axial portions 47, FIG. 13.

(79) The plug 21 is plugged into the plug receptacle 23. A rod-shaped tool 51 is used here, FIG. 14.

(80) Now, the adapter piece 24 is inserted through the mixer opening 49 and attached onto the base plate 9, FIG. 15.

(81) Subsequently, the single-lever mixing cartridge 15 is inserted into the mixer opening 49 and fastened, FIG. 16.

(82) The excess length of the connection hose 39 here is accommodated by the axial portions 47 and/or by way of a meandering routing of the hose.

(83) FIGS. 19 to 23 show an alternative possibility of installing an inner-hose arrangement 44 according to the invention as per FIGS. 17 and 18 in a sanitary fitting 1.

(84) It can be seen from FIGS. 17 and 18 that the maximum outer dimension of the connector piece 16 is smaller than the maximum outer dimension of the connector flange 45. The connector piece 16 thus fits through any opening into which the connector flange 45 with the outlet mouthpiece 5 can be inserted.

(85) In a first step, the inner-hose arrangement 44 is pre-assembled: The connector piece 16 and the connector flange 45 are connected to the connection hose 39, FIG. 18.

(86) In a second step, the inner-hose arrangement 44 is threaded through the outlet opening 46 into the fitting body 2. Here, the connector piece 16 is guided in first, FIG. 29. The base plate 9 here has already been placed into the opening 43 and connected to the hose end pieces 11, 13.

(87) Subsequently, the connector piece is gripped at the connector region 31 using the rod-shaped tool 51, FIG. 20.

(88) Now, the plug 21 is plugged into the plug receptacle 23, FIG. 21.

(89) The length of the connection hose 39 is dimensioned such that the connector flange 45 lies against the inside of outlet opening 46 once the plug 21 has been plugged into the plug receptacle 23, FIG. 22.

(90) Finally, the outlet mouthpiece 5 is screwed in, FIG. 23, and the single-lever mixing cartridge 15 is inserted into the mixer opening 49 (cf. FIG. 16).

(91) In a sanitary fixture 8 having a connector assembly 14 for the connection to a single-lever mixing cartridge 15 it is proposed to pivotably arrange a connector piece 16 having a hose connector 20 on a base plate 9, wherein the base plate 9 has receptacles 10, 12 for a cold-water hose end piece 11 and a warm-water hose end piece 13.
