DETAILED DESCRIPTION

[0036] FIG. 1 shows a sanitary outlet unit denoted as a whole by 1. The sanitary outlet unit 1 has a main body 2 via which it is screwed to a fitting outlet 3 of a fitting, not shown further.

[0037] A seal 4 seals the passage from the fitting outlet 3 to the main body 2.

[0038] The sanitary outlet unit 1 also has a handle 5 via which a screwing movement 6 can be driven. In order to increase the torque which can be introduced, the handle 5 has at least one sliding surface 7. These sliding surfaces 7 can be configured on both sides on the handle 5 in order to permit a drive in both rotational directions.

[0039] The screwing movement path 6 is oriented about a longitudinal axis 8 so that the main body 2 can be screwed in or screwed out.

[0040] FIG. 2 shows a sectional view of the sanitary outlet unit 1. A first jet former 9 and a second jet former 10 are configured in the interior.

[0041] These jet formers 9, 10 serve to set a desired jet pattern.

[0042] Additionally or alternatively, in further exemplary embodiments aerators can be arranged in the interior of the outlet unit 1, a flow rate being able to be reduced thereby and/or a desired value which is independent of pressure being able to be set thereby.

[0043] FIGS. 3-5 show a use of the sanitary outlet unit 1 as intended. FIGS. 4 and 5 show a coupled position in which a drive connection is produced between the handle 5 and the main body 2 by means of a coupling 12.

[0044] In this coupled position, the sanitary outlet unit 1 can be mounted on the fitting outlet 3 or released from the fitting outlet 3 by the screwing movement 6.

[0045] FIG. 3 accordingly shows the uncoupled position in which the coupling 12 is released and thus a drive connection from the handle 5 to the main body 2 is interrupted.

[0046] In this position, the main body 2 cannot be screwed by means of the handle 5.

[0047] In the exemplary embodiment shown, an external thread 13 is configured on the main body 2, the external thread being able to be screwed into a corresponding internal thread 14 in the fitting outlet 3.

[0048] In further exemplary embodiments, not shown in the figures, an internal thread is configured on the main body 2, the internal thread being able to be screwed onto a corresponding external thread on the fitting outlet 3.

[0049] By comparing FIGS. 3-5 it is clear that the handle 5 can be moved to and fro by an axial adjustment movement 15 between the coupled position (FIG. 4 and FIG. 5) and the uncoupled position (FIG. 3).

[0050] FIGS. 6 and 7 show an exploded view of the sanitary outlet unit 1.

[0051] The jet formers 9, 10 are arranged on the internal part 11 which is fastened to the main body 2 so as to be rotatable about the longitudinal axis 8.

[0052] The handle 5 is connected fixedly in terms of rotation but axially movably to the jet former 9 by a sliding guide 16.

[0053] The sliding guide 16 engages in a corresponding guide groove 31 on the handle 5.

[0054] The jet former 9 is arranged inside the jet former 10 so that the jet former 9 forms a central jet 26, while the jet former 10 forms a jet with an annular cross section.

[0055] Two pairs of inlet openings 17 are configured on the internal part 11, wherein a first pair leads to the jet former 9 and a second pair leads to the jet former 10.

[0056] Corresponding outlet openings 19 are configured in the main body 2 (see FIGS. 9 and 10 or 13 and 14) which can be selectively brought into congruence with the first inlet openings 17 or the second inlet openings 18.

[0057] Thus a switching device 20 can be configured, the function thereof being explained in more detail in FIGS. 8-15. FIG. 8 shows the sanitary outlet unit 1 in the uncoupled position.

[0058] In this uncoupled position, a rotational movement of the handle 5 about the longitudinal axis 8 does not lead to a screwing movement 6 of the main body 2 but merely to a rotational movement of the internal part 11 with the jet formers 9, 10. In a first rotational position, according to FIGS. 9 to 11, the outlet openings 19 are arranged so as to correspond to the first inlet openings 17, so that a first water conduit 21 is formed from the inflow side 22 via the jet former 9, 10 to the outflow side 23. The second inlet openings 18 are closed.

[0059] As a result, a jet emerges with an overall annular cross section which is formed from single jets 24.

[0060] If the handle 5 is rotated by 90 in the uncoupled position, the outlet openings 19 are located opposite the second inlet openings 18 while the first inlet openings 17 are closed.

[0061] Thus a second water conduit 25 is formed from the inflow side 22 via the jet former 9 to the outflow side 23. A central jet 26 thus emerges from the sanitary outlet unit 1.

[0062] If the sanitary outlet unit 1 is to be removed, however, the coupling 12 is coupled again by the axial adjustment movement 15 of the handle 5. In this coupled position, no switching takes place between the water conduits 21, 25.

[0063] In FIG. 2, in which the uncoupled position is shown, a latching mechanism 27 is visible as a fixing element, the handle 5 being axially fixed thereby relative to the internal part 11.

[0064] As a result, it can be achieved that the coupled position is not inadvertently reached during use.

[0065] Alternatively or additionally, in further exemplary embodiments, a restoring element can be clamped between the handle 5 and the main body 2 in order to force the uncoupled position.

[0066] The coupling 12 is formed by projections 28 on the main body 2 (as the coupling part), the projections engaging in recesses 29 on the handle 5 (as the counter-coupling part) in the uncoupled position.

[0067] Due to the symmetry of the arrangement of the projections 28 and the recesses 29, the coupling 12 can be coupled in both positions of the switching device 20. This can be identified in FIGS. 8 and 12.

[0068] A dome screen 30 covers the inlet openings 17, 18 on the inflow side.

[0069] The handle 5 is freely rotatable about the longitudinal axis 8. Latching means 32 enable the positions of the switching device 20 to be perceived in a tangible manner.

[0070] In other exemplary embodiments, the switching device 20 can also have limit stops, the handle 5 being freely rotatable therebetween.

[0071] In the sanitary outlet unit 1 according to the invention, it is thus proposed to arrange a main body 2 and a handle 5, which is accessible from outside, so as to be movable relative to each other between a coupled position and an uncoupled position, so that in the coupled position the main body 2 can be screwed to a fitting outlet 3 by means of the handle 5.
