[0034] Figure 1 A sanitary outlet unit is shown, which is designated overall by the reference numeral 1. The sanitary outlet unit 1 comprises a base body 2, with which the sanitary outlet unit 1 is screwed to a fitting outlet 3 of a fitting (not shown in further detail).

[0035] The seal 4 seals the transition between the fitting outlet 3 and the main body 2 .

[0036] The sanitary outlet unit 1 also has a handle 5, by means of which a screwing movement 6 can be driven. In order to increase the torque that can be introduced, the handle 5 has at least one push surface 7. The push surface 7 can be formed on both sides of the handle 5 to allow driving in both rotational directions.

[0037] The screwing movement path 6 is oriented here about a longitudinal axis 8 , so that the main body 2 can be screwed in or out.

[0038] Figure 2 The figure shows a sectional view of the sanitary outlet unit 1. A first beam shaper 9 and a second beam shaper 10 are formed inside.

[0039] The beam shapers 9 , 10 are used to adjust a desired beam pattern.

[0040] In other exemplary embodiments, jet regulators can additionally or alternatively be provided within the sanitary outlet unit 1 , by means of which the flow rate can be reduced and / or regulated to a desired, pressure-independent value.

[0041] Figures 3 to 5 The intended use of the sanitary outlet unit 1 is shown. Figure 4 and 5 A coupled position is shown, in which a drive connection is established between the handle 5 and the basic body 2 via the coupling 12 .

[0042] In this coupled position, the sanitary outlet unit 1 can be mounted on the fitting outlet 3 or detached from the fitting outlet 3 by means of a screwing movement 6 .

[0043] on the contrary, Figure 3 A disengaged position is shown, in which the coupling 12 is disconnected and the drive connection from the handle 5 to the base body 2 is thus disconnected.

[0044] In this position, the base body 2 cannot be screwed on via the handle 5 .

[0045] In the exemplary embodiment shown, an external thread 13 is formed on the main body 2 , which external thread can be screwed into a corresponding internal thread 14 in the fitting outlet 3 .

[0046] In other exemplary embodiments not shown in the figures, an internal thread is formed on the main body 2 , which can be screwed onto a corresponding external thread on the fitting outlet 3 .

[0047] By comparison Figures 3 to 5 It is clear that the handle 5 can be adjusted in the coupling position ( Figure 4 and Figure 5 ) and disconnect position ( Figure 3 ) to move back and forth.

[0048] Figure 6 and Figure 7 An exploded view of the sanitary outlet unit 1 is shown.

[0049] The beam shapers 9 , 10 are arranged on an inner part 11 which is fastened to the base body 2 so as to be rotatable about the longitudinal axis 8 .

[0050] The handle 5 is connected to the beam shaper 10 in a rotationally fixed but axially movable manner by means of a slotted guide 16 .

[0051] The slot guide 16 engages in a corresponding guide groove 31 on the handle 5 .

[0052] The beam shaper 9 is arranged within the beam shaper 10 , so that the beam shaper 9 shapes the central beam 26 , while the beam shaper 10 shapes the beam with an annular cross section.

[0053] Two pairs of inlet openings 17 are formed on the inner component 11 , a first pair of inlet openings leading to the beam shaper 9 and a second pair of inlet openings leading to the beam shaper 10 .

[0054] Corresponding outlet openings 19 are formed in the base body 2 (see Figure 9 and Figure 10 or Figure 13 and Figure 14 ), the outlet hole can selectively coincide with the first inlet hole 17 or the second inlet hole 18.

[0055] Thus, a switching device 20 can be formed, which functions to Figures 8 to 15 Detailed description in. Figure 8 The sanitary outlet unit 1 is shown in the disengaged position.

[0056] In this disengaged position, a rotation of the handle 5 about the longitudinal axis 8 does not result in a screwing movement 6 of the base body 2, but only in a rotation of the inner part 11 with the beam shapers 9, 10. Figures 9 to 11In the first rotational position, the outlet opening 19 is arranged corresponding to the first inlet opening 17, so that a first water conduction path 21 is formed from the inflow side 22 via the jet shapers 9, 10 to the outflow side 23. The second inlet opening 18 is closed here.

[0057] Thus, a beam with an overall annular cross section results, which is formed by a single beam 24 .

[0058] If the handle 5 is rotated through 90° in the disengagement position, the outlet opening 19 lies opposite the second inlet opening 18 , while the first inlet opening 17 is closed.

[0059] As a result, a second water-conducting path 25 is formed from the inflow side 22 via the jet shaper 9 to the outflow side 23. A central jet 26 now flows out of the sanitary outlet unit 1.

[0060] If, on the other hand, the sanitary outlet unit 1 is to be disassembled, the coupling 12 is reconnected by means of the axial adjustment movement 15 of the handle 5. In this connected position, no switching between the water-conducting paths 21, 25 occurs.

[0061] In the disconnected position Figure 2 , a latching mechanism 27 can be seen as a securing element, by means of which the handle 5 is axially fixed relative to the inner part 11 .

[0062] This ensures that the coupling position cannot be reached accidentally during use.

[0063] Alternatively or additionally, in other embodiments, a resetting element may be clamped between the handle 5 and the base body 2 to forcibly maintain the disengaged position.

[0064] The coupling 12 is formed by projections 28 on the base body 2 (as coupling elements), which, in the coupled position, engage in recesses 29 on the handle 5 (as mating coupling elements).

[0065] Due to the symmetry of the arrangement of the protrusions 28 and the recesses 29, the coupling 12 can be coupled in two positions of the switching device 20. Figure 8 and Figure 12 Seen in.

[0066] The prescreen 30 covers the inlet openings 17 , 18 on the inflow side.

[0067] The handle 5 is freely rotatable about the longitudinal axis 8. The latching device 32 allows the position of the switching device 20 to be clearly perceived.

[0068] In other embodiments, the switching device 20 may also have multiple limit stops, and the handle 5 can rotate freely between the limit stops.

[0069] Therefore, according to the invention, in the sanitary outlet unit 1 , the base body 2 and the handle 5 accessible from the outside are arranged movably relative to each other between a coupling position and a decoupling position, so that the base body 2 can be screwed to the fitting outlet 3 via the handle 5 in the coupling position.
