DETAILED DESCRIPTION

(24) Below, FIGS. 1 to 5 will firstly be described jointly.

(25) A sanitary outlet device denoted as a whole by 1 has a housing 2. A jet former receptacle 3 is formed on the housing 2 at the inner side.

(26) An adapter 4 is inserted into the jet former receptacle 3, which adapter is removable from the jet former receptacle 3 in a manner to be described in more detail below.

(27) The adapter 4 defines a flow path 5 for throughflowing water. For this purpose, the adapter 4 is equipped with a jet-altering inner part 31, which may for example form a star-shaped regulating member, a jet regulator, a jet limiter and/or a jet former. Said inner part 31 is, as an insert cartridge 32, inserted into a cartridge receptacle 33 as far as a stop 34. Here, the insertion is performed in a flow direction of the flow path 5, such that the insert cartridge 32 is held in its use position by the stop 34.

(28) The adapter 4 is, in a fixing position as per FIG. 2, locked with the housing 2 in a manner to be described in more detail. The adapter 4 can be transferred by a rotation into the position as per FIG. 3, in which the adapter 4 can be pulled away from the housing 2 and thus out of the jet former receptacle 3. This position as per FIG. 3 is thus a releasing position of the adapter 4.

(29) Viewing the arrangements as per FIG. 5, FIG. 4 and FIG. 3 together, it can be seen that the adapter 4 is insertable into the jet former receptacle 3 counter to a flow direction of the flow path 5. Once the releasing position as per FIG. 3 has been assumed, the adapter 4, which constitutes a flow obstruction in the flow path 5, is forced out of the jet former receptacle 3.

(30) In particular from the completely pulled-away illustration as per FIG. 1 and FIG. 5, it can be seen that the adapter 4 engages around the housing 2 along the entire circumference.

(31) The adapter 4 is arranged so as to be rotatable about an axis of rotation 6 which is oriented along the flow path 5. By this rotation, the adapter 4 can be adjusted between the fixing position and the releasing position.

(32) In relation to said axis of rotation 6, the fixing position as per FIG. 2 and the releasing position as per FIG. 3 are arranged at the same height. Here, the axis of rotation 6 also predefines an insertion direction 7 of the adapter 4 for the insertion into the jet former receptacle 3, such that the fixed position and the releasing position are also arranged at the same height in relation to said insertion direction 7. A transfer movement between the positions thus runs in an axial plane.

(33) In the fixing position, the adapter 4 is locked with the housing 2 on an outer side 8 of the housing 2. For this purpose, a non-circular contour 10 is formed on the outer side 8 at least in one portion 9.

(34) In the exemplary embodiment, said contour 10 is formed by a flattening 11, which interrupts an otherwise encircling groove 12.

(35) It is achieved in this way that, during a rotation of the adapter 4 about the axis of rotation 6, a detent element 13, which in the form of a detent projection 14 engages with detent action into the groove 12 as counterpart detent element 15, is released in the region of the flattening 11. Thus, as soon as the detent element 13 is positioned over the flattening 11, the adapter 4 can be removed from the housing 2. For as long as the detent element 13 is locked with the counterpart detent element 15, the adapter 4 cannot be removed, and the adapter 4 is fixed in the jet former receptacle 3.

(36) The adapter 4 itself is, on the outer side, of non-circular form and has two diametrically mutually oppositely situated handling projections 16. At these handling projections, a user can easily grip the adapter 4 in order to rotate it about the axis of rotation 6 between the fixing position and the releasing position.

(37) It can also be seen in FIG. 1 that the groove 12, as a groove portion 17, is delimited on a circumferential portion 18 of the housing 2. This delimitation is realized at two sides by in each case one flattening 11.

(38) In this way, the releasing position can be assumed in two positions offset by 180°, because the detent element 14, which are likewise delimited in the circumferential direction, can be pulled away from the housing 2 over the flattenings 11.

(39) Said groove portion 17 thus forms a detent receptacle 19 for the detent projection 14.

(40) It can also be seen in FIG. 1 that the detent element 14 is formed on an inner surface 20 of the adapter 4. The inner surface 20 is of uninterrupted encircling form.

(41) This gives rise to particularly good resistance to deformation of the detent projections 14 in a radially outward direction. The locking is thus maintained in a particularly effective manner.

(42) The inner diameter and the inner circumference of said inner surface 20 are in this case adapted to the outer diameter and the outer circumference on the outer side 8 of the housing, such that, in the locked, that is to say fixing, position, the inner surface 20 bears areally against the outer side 8.

(43) The inner surface 20 is thus, between the detent projections 14, supported on the housing 2, whereby increased strength of the locking is realized.

(44) To facilitate locking during the mounting of the adapter 4, a detent projection run-on bevel 21 is formed on the detent projection, which detent projection run-on bevel is oriented in the insertion direction 7 and interacts with a counterpart detent element run-on bevel on the outer side 8 in the region of the counterpart detent element 15.

(45) On the adapter 4, on the outlet side, there is also formed at least one access opening 35 via which a pointed tool can be inserted. Thus, supported for example on the counterpart detent element run-on bevel which serves as guide bevel 36, or in further exemplary embodiments on a separate guide bevel, the detent element 13 can, even without rotation of the adapter 4, be moved out of a position of engagement with the counterpart detent element 15 in order to pull the adapter 4 away.

(46) The jet former receptacle 3 has an inner cone 23, by which said jet former receptacle is formed so as to widen in a flow direction, that is to say along the flow path 5.

(47) The adapter 4 is dimensioned such that it is deformed by the inner cone 23 during insertion into the jet former receptacle 3.

(48) For this purpose, the adapter 4 has, on its inflow-side end 24, 20 an encircling sealing lip 25 comprised of an elastic, rubber-free material, for example comprised of plastic, which is deformed radially inward by the inner cone 23. The sealing lip 25 thus bears sealingly against the jet former receptacle 3.

(49) The inflow-side end 24 of the adapter 4 and the inner surface 20 of the adapter 4 thus receive the housing 2 between them. Here, the adapter 4 may be manufactured from plastic, and may for example have a flow regulator 26 (known per se and not visible in any more detail here) or similar jet former, for example a jet aerator, behind an upstream screen 27 in the interior, approximately at the position denoted by the arrow.

(50) The adapter 4 may additionally or alternatively be formed as an aerated adapter 4, in a manner known per se.

(51) It can also be seen from the figures that the abovementioned inner surface 20 and the outer side 8 each describe, outside the detent element 13 or the counterpart detent element 15, a portion of a body of revolution.

(52) In the exemplary embodiment as per FIG. 1 to FIG. 5, the housing is formed integrally with a fitting outlet 28 of a sanitary fitting 29 which is merely indicated here.

(53) In further exemplary embodiments, the housing 2 may, in a manner known per se, have a thread which can be screwed 15 together with a counterpart thread of the fitting outlet 28.

(54) FIG. 6 shows a further exemplary embodiment according to the invention of a sanitary outlet device. Components and functional units which are similar or identical in terms of function and/or construction to the preceding exemplary embodiments are denoted by the same reference designations, and will not be separately described again. The statements relating to the exemplary embodiments above therefore apply correspondingly to FIG. 6.

(55) The exemplary embodiment as per FIG. 6 differs from the preceding exemplary embodiments in that the non-circular contour 10 is formed with a contour run-on bevel 30. The contour run-on bevels 30 have the effect that the detent 30 projections 14 of the detent element 13 are forced radially out of the groove portions, which in this case are formed analogously to the groove portions 17 in the preceding figures. Thus, the locking is released, and the adapter 4, which is shown in FIG. 6 in the locked, fixing position, can be pulled away from the housing 2.

(56) In the exemplary embodiments shown and described, the detent element 13 is formed on the adapter 4, whereas the counterpart detent element 15 is formed on the housing 2. In further exemplary embodiments, the detent element 13 is formed as a detent projection 14 on the housing 2, whereas corresponding groove portions 17 are formed in the inner surface 20 in order to realize a detent receptacle 19 and thus a counterpart detent element 15. In this case, too, provision may be made whereby, in the inner surface 20, corresponding contour run-on bevels 30 or other non-circular contours 10 are formed in order, in one portion 9 in the circumferential direction of the inner surface 20, to realize a location at which the locking can be eliminated. This location in this case defines the releasing position, whereas the other angular positions of the adapter 4 in the jet former receptacle 3 form the fixing positions. In further exemplary embodiments, other combinations, known per se, of detent element and counterpart detent element are realized.

(57) FIGS. 7 to 9 show a further exemplary embodiment according to the invention of a sanitary outlet device. Components and functional units which are similar or identical in terms of function and/or construction to the preceding exemplary embodiments are denoted by the same reference designations, and will not be separately described again. The statements relating to the exemplary embodiments above therefore apply correspondingly to FIGS. 7 to 9.

(58) The exemplary embodiment as per FIGS. 7 to 9 differs from the preceding exemplary embodiments at least in that the position of the circumferential portion 18 has been rotated through 90°.

(59) Furthermore, a different jet-altering inner part 31 has been inserted in order to define a jet form or jet quality that differs from that in FIG. 1. For this purpose, the insert 5 cartridge 32 can, as shown in FIG. 9, be easily removed from the removed adapter 4 and exchanged.

(60) FIGS. 10 and 11 show a further exemplary embodiment according to the invention of a sanitary outlet device. Components and functional units which are similar or identical in terms of function and/or construction to the preceding exemplary embodiments are denoted by the same reference designations, and will not be separately described again. The statements relating to the exemplary embodiments above therefore apply correspondingly to FIGS. 10 and 11.

(61) The exemplary embodiment as per FIGS. 7 to 9 differs from the preceding exemplary embodiments at least in that the housing 3 is formed separately from a fitting outlet 28. In this exemplary embodiment, a thread 37 on the housing 3—in this case and commonly an external thread—is screwed together with a matching counterpart thread 38—in this case and commonly an internal thread—on the fitting outlet 28. A seal 39, which in a use position is enclosed on all sides by the material of the housing 3 and of the fitting outlet 28, imparts a sealing action between the housing 3 and the fitting outlet 28.

(62) Both the housing 3 and the fitting outlet 28 are manufactured from metal or from some other material that impedes or prevents settling of bacteria. The seal 39 may be manufactured from rubber, because contact with flowing water can be practically ruled out.

(63) For the exchange of the adapter 4 and/or of the jet-forming inner part 31, the housing 3 can remain on the fitting outlet 28.

(64) FIGS. 11 to 14 show a further exemplary embodiment according to the invention. Components and functional units which are similar or identical in terms of function and/or construction to the preceding exemplary embodiments are again denoted by the same reference designations, and will not be separately described again. The statements relating to FIGS. 1 to 10 therefore apply correspondingly to FIGS. 11 to 14.

(65) By contrast to the preceding exemplary embodiments, the adapter 4 has, on the outer side, four handling projections 16 which are distributed uniformly in the circumferential direction.

(66) The detent element 13 and the counterpart detent element 15 are in this case formed with undercuts, resulting in a release angle of greater than 90°.

(67) For this purpose, the detent element 13 and the counterpart detent element 15 have matching oblique surfaces 43, which define a release angle of the detent connection of greater than 90°.

(68) Each of the oblique surfaces 43 is thus, in the insertion direction 7, inclined relative to the respectively corresponding oblique surface 43 such that a lateral deflection of the detent element 13 in the presence of a pulling action on the housing 4 (and thus in the presence of a pressure loading owing to the water pressure) is mechanically prevented. The release angle thus effects interlocking of the detent element 13 with the counterpart detent element 15.

(69) An axially oriented slot 44 in the housing 4 serves for providing the required freedom of movement at the detent element 13, in order that these can be pushed over the counterpart detent element 15.

(70) In this exemplary embodiment, the insert cartridge 32 as jet former 26 is assembled from a splitter part 45 and an outlet part 47. Here, the sealing lip 25 projects, counter to the flow direction, from a main body of the outlet part 47.

(71) Here, the outlet part 47 may be formed integrally with, or inserted into, the adapter 4.

(72) FIGS. 15 to 21 show a further exemplary embodiment according to the invention. Components and functional units which are 15 similar or identical in terms of function and/or construction to the preceding exemplary embodiments are again denoted by the same reference designations, and will not be separately described again. The statements relating to FIGS. 1 to 14 therefore apply correspondingly to FIGS. 15 to 21.

(73) The exemplary embodiment as per FIGS. 15 to 21 differs from the preceding exemplary embodiments at least in that, instead of the sealing lip 17, a sealing ring 40, for example an O-ring comprised of rubber, is provided. Owing to its concealed position, the O-ring is not flushed through despite coming into contact with water.

(74) The jet former 26 is again assembled from a splitter part 45 and an outlet part 47. The outlet part 47 may be integrally connected to the adapter 4, or the outlet part 47 is held by the adapter 4.

(75) On the outlet part 47 and the splitter part 45, there is formed in each case one encircling shoulder 46, which shoulders between them receive the sealing ring 40 and hold said sealing ring axially on both sides. The sealing ring 40 can thus be inserted and removed again together with the adapter 4. In further exemplary embodiments, instead of the shoulders 46, there are formed radially protruding projections which hold the sealing ring 40 axially in portions.

(76) In FIGS. 19 to 21, it can be seen that the arrangement of four handling projections 16 has a correspondent in the arrangement of the counterpart detent elements 15 (and correspondingly of the detent elements 13).

(77) In further exemplary embodiments, a smaller or greater number of handling projections 16, for example three or five or more than five, is formed.

(78) Situated in front of the counterpart detent element 15 in the insertion direction 7 are mounting aids 41, which in this case have the form of indentations 42. The detent elements 13 are in this case dimensioned such that they are bent apart slightly by the cylindrical portion of the housing 2. A user can thus easily sense when the detent elements 13 pass into the circumferential region of the indentations 42 during a rotation of the adapter 4. This thus constitutes a mounting aid 41, because the detent elements 13 are now aligned in relation to the counterpart detent elements 15 (which in this position are possibly already concealed by the adapter 4) and can be easily mounted onto these.

(79) In the case of the sanitary outlet device 1, it is thus generally provided that a jet former receptacle 3 be formed on a housing 2, in which jet former receptacle an adapter 4 is arranged in a removably inserted manner and so as to be rotatable about its axis of rotation 6, wherein the adapter 4 can be rotated between a fixing position, in which the adapter 4 is secured against being removed, and a releasing position, in which the adapter 4 is removable.
