DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(19) FIGS. 1 to 9 show different views of a hose connector assembly 1 according to the invention, and will be described collectively hereunder.

(20) The housing connector assembly 1 has a main body 2 on which three hose receptacles 3, 4, 5 are configured.

(21) One hose 6, 7, 8 having a respective end 9, 10, 11 is plug-fitted into each hose receptacle 3, 4, 5.

(22) Two or more than three hose receptacles and hoses are present in the case of further exemplary embodiments.

(23) A retaining edge 12, 13, 14 in the form of an encircling shoulder is configured on each of the hoses 6, 7, 8 in FIGS. 1 to 9 in the region of the respective end 9, 10, 11, the respective hose 6, 7, 8, being retained by said retaining edge 12, 13, 14 on a retaining plate 15.

(24) To this end, three recesses 16, 17, 18 which in terms of position and size correspond to the hose receptacles 12, 13, 14 and to an external diameter of the ends 9, 10, 11 and of the retaining edges 12, 13, 14 are configured on the retaining plate 15, such that the retaining edges 12, 13, 14 engage across the retaining plate 15.

(25) These recesses 16, 17, 18 are in a plane that is defined by the retaining plate 15 and are oriented outwardly such that the ends 9, 10, 11 by way of an insertion movement 19 that in each case is aligned so as to be transverse to a longitudinal direction of the hoses 6, 7, 8, or is laterally aligned, and runs in the plane can be inserted into the associated recess 16, 17, 18 and when in use are inserted therein. The fixing function of the retaining edge 12, 13, 14 in the axial or longitudinal direction results on account thereof.

(26) The ends 9, 10, 11 are subsequently plug-fitted into the associated hose receptacles 3, 4, 5, and the retaining plate 15 prevents the hoses 6, 7, 8 being pulled out of the respective hose receptacle 3, 4, 5.

(27) A mouth part 20 is attached to the main body 2 on the downstream side, that is to say on a side that is opposite to the hose receptacles 3, 4, 5.

(28) A detent 21, for example as an encircling shoulder 22, is configured on this mouth part 20.

(29) This detent 21 is positioned on the mouth part 20 such that the main body 2 is pressed on the retaining plate 15 when the mouth part 20 is placed onto the main body 2, the retaining plate 15 is externally supported, for example by a counter support, and a force that is directed in the longitudinal direction or toward the retaining plate 15 is exerted on the detent 21.

(30) The hose connector assembly 1 furthermore has a screw sleeve 23 which in the use position impinges the detent 21 and generates the force mentioned.

(31) In the case of further exemplary embodiments, the detent 21 is configured directly on an integral main body 2, wherein the screw sleeve 23 engages directly on the main body 2.

(32) In the case of further exemplary embodiments, the main body 2 or the mouth part 20 is fastened and pressed against the retaining plate 15 with the aid of a non-screwed connection, for example a snap connection, a bayonet connection, or a latching connection.

(33) In the exemplary embodiment according to FIGS. 1 to 9, the screw sleeve 23 is configured as an outlet mouthpiece 24 having a standard dimension used in the sanitary industry.

(34) This outlet mouthpiece 24 is pushed-fitted to the mouth part 20 in such a manner that said outlet mouthpiece 24 receives the mouth part 20 and bears on the detent 21.

(35) It can be seen in FIG. 7 that the recesses 16, 17, 18 by way of their openings 25, 26, 27 point away from one another in a radially outward manner. The plug-fitting movement 19 is thus directed from the outside to the inside.

(36) Moreover, the retaining plate 15 forms a circumferential contour 28 on which the openings 25, 26, 27 in a uniformly distributed and mutually spaced-apart manner open outwardly.

(37) An annular seal 29, 30, 31 is disposed on each hose 6, 7, 8 in the region of the respective end 9, 10, 11. The annular seals 29, 30, 31 in the use position lie between the respective hose 6, 7, 8 and the main body 2 in the respective hose receptacle 3, 4, 5. These annular seals 29, 30, 31 seal the connection of the respective hose 6, 7, 8 on the main body 2.

(38) The mouth part 20 and the main body 2 enclose a complex internal geometry 32 which is closed toward the outside by an annular seal 33.

(39) The hose receptacles 3, 4, 5 are substantially punctiform, as can be seen from FIGS. 1 to 9. The main body 2 has a system of internal connection lines which are not illustrated in more detail here. These connection lines route the hose receptacle 5 toward a dispensing opening 34 which in relation to said connection lines is annular. The dispensing opening 34 is thus connected in a fluid-conducting manner to the hose receptacle 5.

(40) A jet former and/or jet regulator unit 35 which is supplied with liquid by the dispensing opening 34 is configured in the mouth part 20.

(41) By contrast, the hose receptacles 3 and 4 as a bypass 41 are routed past the jet former and/or jet regulator unit 35 such that they in an unimpeded manner open toward the outside, creating a central unified jet.

(42) The retaining edges 12, 13, 14 are in each case configured as lateral delimitations of a retaining groove 36 in order for the ends 9, 10, 11 to be fixed in both axial directions.

(43) It can also be seen in FIGS. 1 to 9 that the annular seals 29, 30, 31 are in each case disposed in a receptacle groove 37.

(44) FIGS. 10 to 12 show a further retaining plate 15 which in the case of the hose connector assembly 1 described is employable instead of the retaining plate 15 as has been illustrated in FIGS. 1 to 9. Components or functional units which in terms of function or construction are equivalent or identical to the preceding exemplary embodiments are identified with the same reference signs and are not described separately once again. Therefore, the explanations pertaining to FIGS. 1 to 9 apply to FIGS. 10 to 12 in analogous manner.

(45) The exemplary embodiment according to FIGS. 10 to 12 differs from the preceding exemplary embodiments at least in that the recesses 16, 17, 18 open inwardly into a common central plug-fitting opening 38 of the retaining plate 15.

(46) The retaining plate 15 thus borders the plug-fitting opening 38 in an annular encircling manner.

(47) In the case of this exemplary embodiment, the hoses 6, 7, 8 in an insertion movement 19 that is guided laterally and from the inside to the outside are insertable into the recesses 16, 17, 18.

(48) In the case of further exemplary embodiments the retaining plate has a system of recesses that are open toward the outside and recesses that are open toward the inside.

(49) FIGS. 15 and 16 show a further hose connector assembly 1 according to the invention. Components or functional units which in terms of function or construction are equivalent or identical to the preceding exemplary embodiments are identified with the same reference signs and are not described separately once again. Therefore, the explanations pertaining to FIGS. 1 to 12 apply to FIGS. 13 and 14 in analogous manner.

(50) The exemplary embodiment according to FIGS. 13 and 14 differs from the preceding exemplary embodiments at least in that the retaining plate 15 is retained only unilaterally by the hoses 6, 7, 8. The retaining edge 14 is thus not joined to form a retaining groove.

(51) The retaining edge 14 in the use position is disposed between the retaining plate 15 and the main body 2 and engages across the retaining plate 15 in order to prevent the respective hose 6, 7, 8 being pulled out.

(52) FIGS. 15 and 16 show a further hose connector assembly 1 according to the invention. Components or functional units which in terms of function or construction are equivalent or identical to the preceding exemplary embodiments are identified with the same reference signs and are not described separately once again. Therefore, the explanations pertaining to FIGS. 1 to 14 apply to FIGS. 15 and 16 in analogous manner.

(53) The exemplary embodiment according to FIGS. 15 and 16 differs from the preceding exemplary embodiments at least in that the annular seals 29, 30, 31 are retained not in a receptacle groove but are retained unilaterally on the respective hose receptacle 3, 4, 5 and on the respective end 9, 10, 11. The annular seals 29, 30, 31, prior to the respective hose being plug-fitted, for assembly can thus either be plug-fitted to the end 9, 10, 11 or be placed into the hose receptacle 3, 4, 5.

(54) In order to be used, the hose connector assembly 1 in the case of the use on a fitting outlet 39 of a sanitary fitting is joined as follows.

(55) First, the hoses 6, 7, 8 are inserted laterally into the retaining plate 15.

(56) The hoses 6, 7, 8 are now subsequently introduced into the respective hose receptacle 9, 10, 11.

(57) Now, the main body 2, with the hoses 6, 7, 8 leading, is inserted into the fitting outlet 39 of the sanitary fitting (not illustrated in more detail).

(58) The retaining plate 15 is now fastened by way of an outlet mouthpiece 24, wherein the latter engages on the detent 21. The retaining plate 15 herein is pressed against a support 40 that is configured in the fitting outlet 39.

(59) The hose connector assembly 1 according to the invention can also be used in the case of further exemplary embodiments for connecting hoses to a mixing valve or a mixing cartridge or any other valve or any other sanitary cartridge.

(60) In the case of a hose connector assembly 1 it is provided that a retaining plate 15 is used for axially fixing at least two hoses 6, 7, 8 in corresponding hose receptacles 3, 4, 5, wherein the hoses 6, 7, 8 by way of a lateral insertion movement 19 are insertable into respective recesses 16, 17, 18 of the retaining plate 15, where said hoses 6, 7, 8 engage behind the recesses 16, 17, 18.
