(9) The connection socket shown in FIGS. 1 to 6 is suitable, for example, for connecting a free-standing mixer fitting for a bathtub or for a shower-column arrangement or the like to a faucet column 1 removably attached to the connection socket. The connection socket comprises a socket bottom body 2, which includes a first bottom body fluid channel 3 with a first bottom body inlet 4 and a first bottom body outlet 5, and also a second bottom body fluid channel 6 with a second bottom body inlet 7 and a second bottom body outlet 8. Furthermore, the connection socket contains a socket top removably attached to the socket bottom body 2 and having a top-side faucet column connection surface 10 and also a first top fluid channel 11 and a second top fluid channel 12. The first top fluid channel 11 has a first top inlet 13 and a first top outlet 14 discharging at the faucet column connection surface 10. Likewise, the second top fluid channel 12 has a second top inlet 15 and a second top outlet 16 discharging at the faucet column connection surface.

(10) The two bottom body fluid channels 3, 6 are formed, in the socket bottom body 2, so as to be fluidically separate from one another, and likewise, the two top fluid channels 11, 12 are formed, in the socket top 9, in a fluidically separate manner. In an operating position, shown in FIG. 1, of the socket top 9, the first top inlet 13 is connected in fluid communication with the first bottom body outlet 5, and the second top inlet 15 is connected in fluid communication with the second bottom body outlet 8. As a result, the first top fluid channel 11 is connected in fluid communication with the first bottom body fluid channel 3, and the second top fluid channel 12 is connected in fluid communication with the second bottom body fluid channel 6. The two bottom body inlets 4, 7 may be connected in particular to a cold-water connection or a hot-water connection of a domestic water supply or sanitary installation of the building such that cold water and hot water can be supplied separately to the faucet column 1 via the two fluidically separate connection socket channels which consist in each case of the bottom body fluid channel 3, 6 in question and the top fluid channel 11, 12 connected thereto. Correspondingly, the faucet column 1 has two separate lines or water guides 17, 18 with associated inlets 17a, 18a which are connected in fluid communication with the first top outlet 14 and the second top outlet 16, respectively. The water guides 17, 18 lead in a conventional manner (not shown) to a head of the faucet column, in which head an associated mixer unit or a fitting unit for controlling the water quantity and the cold-water/warm-water mixing ratio is situated.

(11) The connection socket is connected to the sanitary domestic installation in a conventional manner below a floor level, and is preferably covered by a cover cap 19 which extends in a likewise conventional manner (not shown here) as far as a floor level, such as a bathroom tile level or shower-room floor level, or slightly above this, and is optionally covered by a cover rose which the upwardly-continuing faucet column 1 surrounds.

(12) As can be seen further from FIG. 1, a respective sound absorber element 20, 21 is disposed in each of the two bottom body fluid channels 3, 6 and can be inserted into the bottom body fluid channel 3, 6 in question and extracted therefrom again via the associated first or second bottom body outlet 13, 15 if the socket top 9 has been detached from the socket bottom body 2. For the sound absorber elements 20, 21, those of conventional design are usable. In the case of the connection socket according to FIG. 1, the sound absorber elements 20, 21 are especially disposed in an output-side section 3b, 6b of the bottom body fluid channel 3, 6 in question, wherein the output-side section 3b, 6b extends in each case in a manner inclined at an angle 1, 2 of less than 70 in relation to a bottom-plane parallel input-side section 3a, 6a of the respective bottom body fluid channel 3, 6. Preferably, this oblique angle 1, 2 is less than 45, and in the example shown it lies in the range between 25 and 30.

(13) A backflow preventer element 22, 23 of conventional design is disposed in each of the two top fluid channels 11, 12 and can be inserted into the top fluid channel 11, 12 in question and extracted therefrom again via the associated first or second top outlet 14, if the faucet column 1 has been demounted from the socket top 9.

(14) The top-side faucet column connection surface 10 of the socket top 9 can, as shown, advantageously have a spherical cap shape in order to allow, to a corresponding extent, tilting of the faucet column 1 with its longitudinal axis in relation to a longitudinal axis L of the socket top 9, and thus vertical alignment of the faucet column 1. For this purpose, the faucet column 1 has on its underside a correspondingly spherical-cap-shaped connection surface 24. In the aligned state, the faucet column 1 can then be fixed by means of a fixing ring 25, which acts on a ring shoulder 26 of the faucet column 1, and screw connections 27 on the socket top 9, as can be seen in particular from FIG. 4.

(15) In the example shown in FIG. 1, the socket top 9 is attached to the socket bottom body 2 so as to be turnable by means of a bayonet connection 28 between the operating position shown in FIG. 1 and a blocking position. In the blocking position, the fluid communication of the respective top inlet 13, 15 with the corresponding bottom body outlet 5, 8 is blocked. FIGS. 4 and 5 show the connection socket in the blocking position, while FIGS. 1 to 3 show the connection socket in the operating position. In the exemplary embodiment shown, the socket bottom body 2 and the socket top 9 have for this purpose corresponding frustoconical abutment surfaces 29, 30, on which the bottom body outlets 5, 8 and the top inlets 13, 15, respectively, are located. Preferably, the socket top 9 is secured in the operating position in that it is additionally removably fixed, for example by way of screw connections 31 as shown in FIG. 2, to the socket bottom body 2. This fixing is released if the socket top 9 is to be turned in relation to the socket bottom body 2.

(16) The turning of the socket top 9 in relation to the socket bottom body 2 from the operating position to the blocking position and back occurs over a turning angle range which is sufficient for turning the top inlets 13, 15 completely out of from the region of the bottom body outlets 5, 8. The turning of the socket top 9 occurs about its longitudinal axis L as the turning axis, wherein the faucet column 1 can be turned along therewith if it is attached to the socket top 9. In the example shown, the turning angle range between the operating position and the blocking position is discernible from a comparison of FIGS. 3 and 5, and, as can be seen therefrom, is approx. 35, represented by an angle in FIG. 5.

(17) Since, as a consequence, in the blocking position of the socket top 9, the fluid channels 11, 12 thereof are blocked in relation to the bottom body fluid channels 3, 6 connected to the water supply, the fluid supply to the socket top 9, and thus also to the faucet column 1, is then interrupted, and it is possible for repair or maintenance work to be performed on the faucet column 1 or on the socket top 9, without having to shut off water elsewhere, for example at an upstream shut-off valve of the sanitary installation in the building. In particular, in the blocking position of the socket top 9, it is possible for the faucet column 1 to be detached from the socket top 9 by releasing the fixing 27, and subsequently for the two or one of the two backflow preventer elements 22, 23 to be extracted from the socket top 9 and if appropriate replaced by new backflow preventer elements.

(18) For repair or maintenance of the sound absorber elements 20, 21, the socket top 9 is dismounted from the socket bottom body 2, whereupon the sound absorber elements 20, 21 are accessible via the bottom body outlets 5, 8 in question, and can be repaired or replaced. For this purpose, the socket top 9 is turnable about its longitudinal axis L in relation to the socket bottom body 2, due to the bayonet connection, between the operating position according to FIGS. 1 to 3 and a dismounting position, wherein the dismounting position has a greater turning angle distance from the operating position than the blocking position, and wherein the blocking position is a surmountable intermediate position, for example in the form of a passable locking means or of a releasable stop. In the example shown in FIGS. 1 to 6, the blocking position is defined as a releasable stop by screw-in stop pins 32 which are visible from FIG. 6, wherein the stop pins 32 are screwable from the socket top 9 into the socket bottom body 2 and act as a releasable stop for the turning movement, by way of the bayonet connection 28, in the blocking position. After screwing out the stop pins 32, it is consequently possible for the socket top 9 to be turned in relation to the socket bottom body 2 beyond the blocking position to the dismounting position. In the dismounting position, the bayonet connection 28 is released, and so the socket top 9 can be detached from the socket bottom body 2.

(19) FIGS. 7 and 8 illustrate two variants of the exemplary embodiment in FIGS. 1 to 6, wherein, for the sake of easier understanding, the same reference signs are used for identical and functionally equivalent elements, and it is possible in this respect to make reference to the above explanations for FIGS. 1 to 6, and so, in the following text, only the differences are addressed in greater detail.

(20) In the exemplary embodiment in FIG. 7, the backflow preventer element 22 is disposed in a lower region 1a, which is modified in this respect, of the faucet column 1. Furthermore, the channel guide of the two top fluid channels 11, 12 is slightly modified, as can be seen from FIG. 7 compared with FIG. 1. Correspondingly, the spherical-cap-shaped faucet column connection surface 10 of the socket top 9 is formed by a capped spherical segment that is flat on top instead of a semicircular shape as in the example in FIG. 1.

(21) In the exemplary embodiment in FIG. 8, both backflow preventer elements 22, 23 are disposed in the lower region 1a of the fitting column 1 instead of in the socket top 9 as in the example of FIGS. 1 to 6. In turn, the two top fluid channels 11, 12 are modified in their extent in relation to that in the exemplary embodiments in FIG. 7 or in FIGS. 1 to 6, as can be seen from a comparison of FIG. 8 with FIG. 7 or FIG. 1.

(22) In further exemplary embodiments of the invention, which are not shown, a sound absorber element is disposed only in one of the two bottom body fluid channels or there are no sound absorber elements there. Furthermore, the invention includes exemplary embodiments (not shown) in which the turnability of the socket top in relation to the socket bottom body is realized not by way of a bayonet connection but by way of another conventional turn connection, for example with the use of a suitable rotary slotted link guide. The invention furthermore includes exemplary embodiments in which the socket top is attached to the socket bottom body so as to be turnable only between the operating position and the blocking position, without being turned further into a dismounting position, and also exemplary embodiments in which the socket top is removably attached to the socket bottom body in a rigid manner, without being able to be turned in relation thereto.

(23) As the exemplary embodiments shown and explained above make clear, the invention provides a connection socket with which sanitary fittings with a floor-standing faucet column can be connected to an associated water supply in a very advantageous manner.
