The control part 12 has a circular-cylindrical housing 40 which is fixedly connected to the further sleeve-shaped base 38. The further sleeve-shaped base 38 rests with a further flange 42, in particular a further base panel 42 ', on the upper side 24 of the table top 16 and in a known manner on the underside 26 of the table top 16 with another threaded nut (not shown) in Position held.

In the interior of the circular cylindrical housing (not shown) a single lever mixing cartridge (not shown) is arranged in a known manner. To the Einhebelmischpatrone lead a hot water pipe 46 and a cold water pipe 48.

A Einhebelbetätigungselement 50 controls by means of a pivoting movement about a horizontal axis, the amount of water of the hot water pipe 46 and cold water line 48. The mixing water produced with the Einhebelmischpatrone mixed water is, via a mixed water line 52, which is connected via a further connection 54 to the water supply line 36 to a water outlet 56th guided.

Further, the single-lever mixing cartridge controls, in a known manner, by a rotational movement of the Einhebelbetätigungselemtes 50, about a vertical axis, the water temperature of the mixed water.

A support 58 of the outlet part 14 is mounted below the table top 16 on the base 20 and carries at a defined distance from the table top 16 a final brake 60, the brake pad 62 is intended to cooperate with a stop plate 64.

The stop plate 64 is fixedly attached to the lower feed side end 66 of the outlet pipe 18 and serves as a stop 64 'for the rectilinear outlet pipe 18 at a lowered rest position 68 according to Fig. 2 , As soon as the stop disk 64 comes into abutment with the end brake 60, the downward movement of the outlet pipe 18 is taken up by the brake tappet 62 of the end brake 60 and braked until the lowered rest position 68 is reached.

Illustrated is the lowered rest position 68 of the sanitary fitting 10 in Fig. 2 and 3 shown in longitudinal section, wherein for the sake of simplicity not the table top 16 and not the interaction of the end brake 60 are shown with the stop plate 64. Fig. 3 clearly shows that in the lowered rest position 68, a magnetic holding system 70 (see Fig. 2 to 7 ) unfolds no effect, but only the gravity can stop the stop plate 64 from the outlet pipe 18 in the direction of the end brake 60.

From the lowered rest position 68, the outlet pipe 18 can be displaced in the direction towards the top, with an intermediate position 72 as in Fig. 1 . 6 , and 7 can be approached shown. The intermediate position 72 is between the lowered rest position 68 and an extended working position 74 (see Fig. 4 and 5 ).

From the intermediate position 72 can either be driven back down to the rest position 68 or further up into the extended working position 74.

From the extended working position 74 can be moved down, only the intermediate position 72 and then the lowered rest position 68 can be approached.

The magnetic holding system 70 acts accordingly only in the intermediate position 72 and in the extended working position 74th

The in Fig. 2 shown longitudinal section, shows the sanitary fitting 10 according to the invention Fig. 1 in the lowered rest position 68, wherein the outlet head 32, preferably designed as a Perlator®, the water outlet 56 forms and the outlet pipe 18 about 5 cm from the table top 16 (see Fig. 1 ) stands out.

The outlet arm 30 has a hollow body 76 with an approximately rectangular cross section and is fixedly connected to the rectilinear, circular cylindrical outlet pipe 18 of the outlet part 14. Accordingly, the inflowing water freely from the control part 12 (see Fig. 1 ) to the water outlet 56.

The outlet pipe 18 is designed as a rectilinear, circular cylindrical hollow body 78, the interior of which is designated by 78 ', which is mounted and guided in the base 20 by means of the sliding guide 21. The outlet pipe 18 is supply side connected by means of the terminal 34 with the water supply line 36, in particular the flexible water hose 36 '.

Preferred material for the outlet pipe 18 and the base 20 is a non-magnetizable metal or metal alloy, such as non-ferrous metal or chrome steel.

At the supply-side end region 80 of the base 20, a stationary part 82 of the magnetic holding system 70 is arranged. The stationary part 82 is formed by an outer magnet 84, which in connection with Fig. 3 will be explained in more detail below.

In the interior 78 'from the outlet pipe 18 of the inner magnet 88 and the further inner magnet 90 is fixed. The inner magnet 88 and the further inner magnet 90 serve to be arranged in the extended working position 74 and in the intermediate position 72 in the outer magnet 84 in order to form the corresponding holding force. The magnetic interaction of the outer magnet 84 with the inner magnet 88 and optionally the further inner magnet 90 is shown in FIG Fig. 5 and 7 shown in enlarged illustration.

In the interior 78 'of the outlet pipe 18 is on the supply side, a transition piece 94 and give this outlet side a holding nozzle 92 is arranged. Correspondingly, the inner magnet 88 for the extended working position 74 is located on the outlet connection 94 on the outlet side, and the additional inner magnet 90 for the intermediate position 72 bears against the supply connection 92 on the supply side.

The holding stub 92 and the transition stub 94 each have a central, axial passage 96, 98, wherein these two passages 96, 98 are connected to one another via a conduit 100 in order to separate the water from the inner magnet 88 and the further inner magnet 90.

Sealing rings 102, in particular O-ring seals 102 ', seal the holding connection 92 and the transition connection 94 with respect to the conduit 100.

Between the inner magnet 88 and the further inner magnet 90 extends a spacer sleeve 104, so that the magnets 88, 90 are held spaced in the longitudinal direction. The spacer sleeve 104 is arranged in the radial direction between the conduit 100 and the outlet pipe 18.

The holding nozzle 92 rests with its outlet side against an inner shoulder 106 of the outlet pipe 18 and is sealed by means of O-ring seals 102 'to the outlet pipe 18. An end region of the outlet pipe 18 adjoining the feed side end 66 of the outlet pipe 18 is provided with an internal thread 108, into which the transition pipe 94 with corresponding external thread 110 is screwed. As a result, the holding nozzle 92 is pressed against the inner shoulder 106 of the outlet pipe 18. Thus, the inner magnet 88 and the further inner magnet 90 is held firmly in the interior of the outlet pipe 18 and positioned.

As related to Fig. 1 explained, the stop disk 64 is arranged at the outlet end of the outlet pipe 18. The transitional benefit 94 has at its supply-side end in the adjoining end region on another external thread 111. On this external thread 111, the clamping sleeve 34 'is screwed with its corresponding internal thread 113, wherein the stop plate 64 is clamped between the clamping sleeve 34' and the outlet pipe 18 is held.

On the feed side, the clamping sleeve 34 'is screwed to a rotary connection 112 of the water hose 36', so that the water hose 36 'can rotate independently of the outlet pipe 18.

The flexible water hose 36 'is provided with a metallic adapter 115 and at its outlet-side front end portion with an internal thread 115'. This internal thread 115 'of the metallic adapter 115 is screwed to an external thread 114' of an inner sleeve 114 and rotatably sealed with mechanical seals 116 against an outer sleeve 118.

The metallic adapter 115 of the water hose 36 'is sealed by means of O-ring seals 102' relative to the outer sleeve 118.

The rotary connection 112 of the water hose 36 'is correspondingly formed from the inner sleeve 114, the metallic adapter 115 of the water hose 36' and the outer sleeve 118, as shown clearly in the Fig. 5 and 7 shown in detail.

Preferably, the rectilinear outlet pipe 18 has a circular cylindrical outer surface 120, which extends at least in the cooperating with the sliding guide 21 of the base 20 area and correspondingly allows the rotation of the rectilinear outlet pipe 18 of the sanitary fitting 10. Preferably, the outer circumferential surface 120 of the outlet pipe 18 over the entire length of the outlet pipe 18 is circular cylindrical.

In Fig. 3 is clearly the arrangement of the outlet pipe 18 to the base 20 and the stationary part 82 of the magnetic holding system 70 shown, wherein the outlet pipe 18 is shown in the lowered rest position 68.

On the radial inner surface of the sleeve-shaped base 18, the sliding guide 21 is fixed, which supports the outlet pipe 18 and the outlet pipe 18 allows a shift between the lowered Ruhepositon 68 and the extended working position 74 and turning.

The sliding guide 21 is preferably tubular and made of plastic, such as nylon or Teflon executed.

The sleeve-shaped part 121 of the base 20 is provided with an external thread 122 'on the outer casing 122 and has the flange 22 on the outlet side, which carries a further external thread 122 "on the further external thread 122", the base plate 22' is screwed.

The base panel 22 'has an open towards the table top 16 annular groove 124 in which an O-ring seal 102' is arranged. This is pressed against the top 24 of the table top 16 and thus prevents the ingress of water or dirt particles.

At the base panel 22 'with lip a lubricious sealing collar 126 in the axial direction of the outlet pipe 18 and prevents the penetration of dust particles in the sliding guide 21, which could lead to scratching of the outlet pipe 18.

On the external thread 122 'of the base 20, the threaded nut 28 is screwed. On the threaded nut 28 is a washer 28 'on. On the opposite side of the support 58 is arranged, which comes by tightening the threaded nut 28 on the bottom 26 of the table top 16 to the plant.

The stationary part 82 of the magnetic holding system 70 consists of the outer magnet 84 which is held by a nut 128 and a cap nut 130 in position. The nut 128 is tightened to block and is correspondingly with an inner shoulder 128 'of the nut 128 at the supply-side end 80 of the external thread 122' from the base 20 at.

The union nut 130 is screwed to the external threads 132 of the nut 128 and the internal thread 134 of the nut 128 is screwed at the supply-side end 80 of the base 20 with its external thread 122 '.

The outer magnet 84 is designed here as a ring magnet 84 '. In the axial direction, from the water outlet 56 (see Fig. 2 ), the outer magnet 84 is constructed successively with a first permanent magnet ring 138, a magnetizable iron ring 140 and a second permanent magnet ring 142, wherein the poles of the permanent magnet rings 138, 142 are oppositely poled in the axial direction to each other and correspondingly magnetize the iron ring 140.

Between the outlet pipe 18 and the outer magnet 84 is a small air gap 139 in order to prevent injuries to the lateral surface 120 of the outlet pipe 18.

The iron ring 140 forms a so-called pole piece 140 ', so that the magnetization of the iron ring 140 preferably leads to a pole saturation. Accordingly, the first permanent magnet 138 in the axial direction, viewed from the outlet ago, north-south poled and the second permanent magnet 142 in the axial direction, viewed from the outlet ago, south-north poled, so that the iron ring 140 and the pole piece 140 'a South Pol forms.

In the present case, the first permanent magnet ring 138 as well as the second permanent magnet ring 142 is formed by a respective pair of magnetic rings having the same magnetic properties and geometries. However, it is also conceivable to use only a single magnetic ring, which has the same thickness as the respective pair of magnetic rings, instead of the magnetic ring pair.

In the lowered rest position 68, neither the inner magnet 88 nor the further inner magnet 90 interacts with the outer magnet 84.

In Fig. 4 is the longitudinal section of the inventive embodiment according to Fig. 1 shown, wherein the outlet pipe 18 is in the extended working position 74 and accordingly protrudes about 30 cm from the table top 16.

It is off Fig. 4 clearly seen that in the extended working position 74 of the stationary part 82 of the magnetic holding system 70 and the opposite pole 86 of the inner magnet 88 cooperates. According to detail is mentioned facts in Fig. 5 shown in longitudinal section shown.

The magnetic interaction between the outer magnet 84 and the inner magnet 88 determines the magnetic holding force for the extended working position 74, wherein in the axial direction of the outer magnet 84 and the inner magnet 88 are opposite. The inner magnet 88 is designed here as a ring magnet 88 '. Seen in the axial direction from the water outlet 56 forth, the inner magnet 88 is constructed successively with a first permanent magnet ring 144, a magnetizable iron ring 146 and a second permanent magnet ring 148, wherein the poles of the permanent magnet rings 144, 148 are oppositely poled in the axial direction to each other and corresponding to the iron ring 146th magnetize.

The iron ring 146 of the inner magnet 88 likewise forms a pole shoe 146 ', as in the case of the outer magnet 84, so that the magnetization of the iron ring 146 preferably leads to a pole saturation. Accordingly, the first one Permanent magnet 144 in the axial direction, viewed from the outlet ago, south-north poled and the second permanent magnet ring 148 in the axial direction, viewed from the outlet ago, north-south poled, so that the iron ring 146 and the pole piece 146 'of the inner magnet 88 a north -Pol forms and in the radial direction in the extended working position 74 with the outer magnet 84 cooperates.

Preferably, the inner magnet 88 is formed asymmetrically for the extended working position 74, so that the holding force up by a factor of 2 to 3, here by a factor of 3, is greater than down. This situation supports the holding function of the magnetic holding system 70 in the extended working position 74 such that a further retraction of the outlet pipe 18 is difficult, but the lowering of the outlet pipe 18 is easier because the holding force down by a factor of 3 is smaller. If the holding force is overcome during retraction of the outlet pipe 18 in the extended working position 74, the stop plate 64 comes to the union nut 130 to the plant.

In the present case, the second permanent magnet ring 148 of the inner magnet 88 is formed of three ring magnets having the same magnetic properties and geometries, but it is also conceivable to use only one magnet, which has the same thickness as the three-magnet arrangement, instead of the three magnets , Also, the first permanent magnet ring 144 of the inner magnet 88 has the same magnetic properties and geometries, but the first permanent magnet ring 144 is oppositely poled with respect to the second permanent magnet ring 148.

The geometric arrangement of the further inner magnet 90 relative to the inner magnet 88, is selected such that in the extended working position 74, the inner magnet 88, seen in the axial direction, is at least approximately still in the base 20.

In Fig. 6 is the longitudinal section of the inventive embodiment according to Fig. 1 shown, wherein the outlet pipe 18 is located in the intermediate position 72 and accordingly protrudes about 20 cm from the table top 16.

It is off Fig. 6 clearly seen that in the intermediate position 72, the stationary part 84 of the magnetic holding system 70 and the further inner magnet 90 cooperate. Accordingly detailed fact is described in Fig. 7 shown in longitudinal section shown.

The magnetic interaction between the outer magnet 84 and the further inner magnet 90 determines the holding force for the intermediate position 72. The further inner magnet 90 is designed here as a ring magnet 90 '. As seen in the axial direction from the water outlet 56 forth, the further inner magnet 90 is constructed successively with a first permanent magnet ring 150, a magnetizable iron ring 152 and a second permanent magnet ring 154, wherein the poles of the permanent magnet rings 150, 154 are oppositely poled in the axial direction to each other and corresponding to the iron ring 152 magnetize.

The iron ring 152 of the further inner magnet 90 likewise forms, as in the case of the outer magnet 84 and the inner magnet 88, a pole shoe 152 ', so that the magnetization of the iron ring 152 preferably leads to a poling saturation. Correspondingly, the first permanent magnet ring 150, viewed in the axial direction from the water outlet 56, is poled south-north and the second permanent magnet ring 154, viewed in the axial direction from the water outlet, poles north-south, so that the iron ring 152 or the pole shoe 152 ' from the further inner magnet 90 forms a north pole and cooperates in the radial direction in the intermediate position 72 with the outer magnet 84.

Preferably, the further inner magnet 90 is formed symmetrically for the intermediate position 72, so that the holding force has the same Karftwirkung up and down. Accordingly, the process from the intermediate position 72 is connected by pulling upwards or pushing downwards with the same effort. Wherein when pushing down in the direction of lowered rest position 68, the weight of the outlet pipe 18 supports the shock movement and is therefore perceived as lighter. The process from the intermediate position 72 to the extended working position 74 may be felt to be more severe because not only the holding force of the magnetic action but also the weight of the spout 18 must be overcome.

In the present case, the first permanent magnet ring 150 as well as the second permanent magnet ring 154 is formed by a respective pair of magnetic rings having the same magnetic properties and geometries but oppositely poled to polarize the pole piece 152 '. However, it is also conceivable to use only a single magnetic ring, which has the same thickness as the respective pair of magnetic rings, instead of the magnetic ring pair.

The operation of the embodiment shown in the figures is as follows.

In the lowered rest position 68 is the outlet pipe 18, as in Fig. 2 shown, to about 5 cm above the table top 16, so that the stationary part 82 of the magnetic holding system 70 interacts neither with the inner magnet 88 nor with the other inner magnet 90. The outlet pipe 18 is held by its weight in the lowered rest position 68.

From the lowered rest position 68, the outlet pipe 18, by manual pulling, up, are brought into the intermediate position 72, as in Fig. 6 shown, wherein the outlet pipe 18 is arranged corresponding to about 20 cm above the table top 16 and thus is between the lowered rest position 68 and the extended working position 74. In this intermediate position 72, the magnetic holding system 70 acts such that the outer magnet 84 cooperates with the further inner magnet 90.

From the intermediate position 72 can either be driven again, by manually pushing down, in the lowered rest position 68 or by manual pulling, upwards in the extended working position 74. Accordingly, the magnetic holding force in the intermediate position 72 is preferably the same for both directions.

Preferably, the holding force could be in the intermediate position 72 in the range of about 30 kN to a maximum of 50 kN.

In the extended working position 74 is the outlet pipe 18, as in Fig. 4 shown up to about 30 cm arranged above the table top 16, so that the outer magnet, 84 interacts with the inner magnet 88. From the extended Arbeitsspositon 74 can be driven by poking down into the intermediate position 72 or further directly into the lowered rest position 68.

The magnetic holding force for the extended working position 74, can be in the range of about 35 kN to a maximum of 40 kN.

It is of course also conceivable for the present embodiment that only the inner magnet 88 and no further inner magnet 90 are arranged in the inner space 78 'of the outlet pipe 18. Accordingly, the magnetic retention system 70 would only have an effect in the extended working position 74.

In a further embodiment of the present invention, the outlet pipe 18 can be designed circular arcuate. Correspondingly, the sliding guide 21 of the base 20 would also be curved in a circular arc, which allows the outlet pipe 18 to be moved from the rest position 68 into the extended working position 74 and back, but rotation in the sliding guide 21 would not be possible.

In a further embodiment of the present invention, the base 20 of the outlet part 14 above the table top 16 could be made larger in order to receive the mixing cartridge in a recess as is well known. Accordingly, no separate control part 12 would be needed.

In a further embodiment of the present invention, it is conceivable that the outer magnet 84, the Inner magnet 88 and optionally the further inner magnet 90 are not formed as a ring magnet, but as a generally known permanent magnet.

In a further embodiment of the present invention, in the stationary part 82 of the magnetic holding system 70, the outer magnet 84 could be replaced by a magnetizable iron ring, so that the inner magnet 88 and the further inner magnet 90 cooperate with the magnetizable iron ring.

In a further embodiment of the present invention, the inner magnet 88 and possibly the further inner magnet 90 could be replaced by the magnetizable iron ring, so that they interact with the outer magnet 84.

In a further embodiment of the present invention, the outer magnet 84 could be arranged at the outlet end portion 81 of the base 20, preferably provided with a magnetic field shield.

In a further embodiment of the present invention, the outer magnet 84, the inner magnet 88 and optionally the further inner magnet 90 could be designed as an electromagnet.
