Sanitary fitting

Abstract

A sanitary fitting having an outlet contains an outlet end which is formed in a substantially tubular manner. In this tubular end there is arranged a shut-off valve having a cartridge, water flowing through the center of said shut-off valve. A rotary shaft serves to rotate and thus actuate the valve cartridge. The rotary shaft is arranged and mounted inside a mounting sleeve which contains an outlet element at its outlet-side end. An external sleeve, which forms a flush continuation of the fitting housing, serves to rotate the rotary shaft. The sleeve is connected to the rotary shaft by a radial pin which engages through an arcuate slot that extends in the circumferential direction. When the sleeve is rotated, the position and setting of the outlet element remains the same.

Description

(1) Further features, details and advantages of the invention will become apparent from the claims and the abstract, the wording of both of which is incorporated into the content of the description by reference, from the following description of preferred embodiments of the invention and by way of the drawing, in which:

(2) FIG. 1 shows a view of a sanitary fitting according to the invention;

(3) FIG. 2 shows an axial section through the fitting housing in the region of the outlet;

(4) FIG. 3 shows an axial section through the fitting housing in the region of the outlet;

(5) FIG. 4 shows a further axial section in the region of the outlet;

(7) FIG. 6 shows an axial section corresponding to FIG. 4, with the change-over device adjusted;

(8) FIG. 7 shows a section corresponding to FIG. 5 through the arrangement in FIG. 6.

(9) FIG. 1 shows a view of a sanitary fitting having a fitting housing 1. The fitting housing 1 contains a vertical pipe 2, from the underside 3 of which a threaded sleeve 4 projects. The threaded sleeve 4 has a smaller diameter than the bottom end 3 of the vertical pipe 2. The threaded sleeve 4 is provided with an external thread. Screwed onto the latter is a nut 5, which serves to fix the sanitary fitting in a through-opening in a panel. Screwed into the nut 5 are two screws 6, which act on a pressure plate 7. For the purpose of fastening, the threaded sleeve 4 is fitted through the mentioned hole, the pressure plate 7 is threaded on from below, and the nut 5 is screwed in. For final tightening, the screws 6 are tightened.

(10) At the top end of the housing 1 of the sanitary fitting there is arranged an actuating element 7 in the form of a rotary cap which is used to actuate a mixing valve by way of which for example the temperature of the water exiting the sanitary fitting is fixed.

(11) Formed at the bottom end, remote from the rotary cap 7, of the fitting housing is an outlet 8 10 which is surrounded by a sleeve 9. The sleeve 9 extends flush or approximately flush with the fitting housing 1, which is formed in a tubular manner in the region immediately adjoining the sleeve 9. Water flows out of the end side of the outlet 8 with the valve open.

(12) The following figures are now limited to details of the fitting housing 1 in the region of the outlet. In this region, the fitting housing 1 is formed in an approximately tubular manner, and the rotary sleeve 9 represents a continuation of the external form of the fitting housing 1.

(13) Arranged in the fitting housing 1 is a valve bottom 10 which is pushed by way of its upstream inlet region 11 onto an output 12 from the mixing valve.

(14) Through the valve bottom 10 there leads a central through-passage 13, which opens into the receptacle 14 of the valve bottom 10. Inserted into this central receptacle 14 is a valve cartridge 15. At the output of the valve bottom partially surrounding the valve cartridge 15, a holding sleeve 16 is inserted into the fitting housing 1 and fixed there. The holding sleeve 16 extends as far as just before the outlet from the sanitary fitting.

(15) In its front region facing the outlet 8, the holding sleeve 16 contains an inner receptacle 17, into which an intermediate element 18 is inserted. An outlet element 19 is inserted into the holding sleeve 16 at its end facing the outlet 8, the outlet element 19 being a jet regulator. The outlet element 19 has a partially spherical outer side, which is accommodated in a correspondingly shaped mating surface so that the outlet element 19 can be pivoted within a particular angular range.

(16) Mounted on the holding sleeve 16 is the sleeve 9 that forms the actuating element. Said sleeve can be rotated about the holding sleeve 16 connected in a rotationally fixed manner to the sanitary fitting.

(17) The valve cartridge 15, which forms a shut-off valve, contains, on its side facing the outlet 8, a hollow adjusting element 21 provided with an external toothing 20. When the shut-off valve is open, the water flows through the valve cartridge 15 and through the hollow adjusting element 21.

(18) Arranged in the radial direction within the holding sleeve 16 is a rotary shaft 22 which is guided by way of its lateral surface on the inner surface of the holding sleeve 16. The rotary shaft has, in its end region facing the valve cartridge 15, an opening which is formed in a complementary manner to the outer side of the adjusting element 21. As a result, a rotation of the rotary shaft 22 results in a rotation of the adjusting element 21 of the valve cartridge 15. The rotary shaft 22 has a blind bore 23 located in the extension of the adjusting element 21, said blind bore ending at a bottom. In the region of the bottom, channels 24 lead in the radial direction out of the rotary shaft 22.

(19) A rotation of the sleeve 9 forming the actuating element for the shut-off valve 15 results in a rotation of the rotary shaft 22, as will be shown in the following text. Depending on the position of the rotary shaft 22, as soon as the valve cartridge 15 is open, the water runs to the various outlet possibilities from the outlet 8.

(20) An example is illustrated in FIG. 3. FIG. 3 shows the outlet end from the sanitary fitting in a position in which the channels 24 are located in the section plane. In this position, the channels 24 are located in a manner corresponding to angled channels 25 in the holding sleeve 16, which open into the receptacle 17. From there, the water runs towards the outside through a narrow intermediate space between the insert 18 and the holding sleeve 16. The water thus flows past the outlet element 19, specifically on the outer side of the latter.

(21) Now to FIG. 4. FIG. 4 shows that the sleeve 9 forming the actuating element has a pin 26 which engages, through a slot 27 in the holding sleeve 16, into a blind bore in the rotary shaft 22. In this way, a rotation of the sleeve 9 results in a rotation of the rotary shaft 22.

(22) FIG. 5 shows a cross section through the outlet end of the sanitary fitting. The rotary shaft 22 is in a position in which the channels 24 are closed by the wall of the holding sleeve 16. The section of FIG. 5 likewise shows that the channels 25 in the holding sleeve 16 are arranged diametrically. If the rotary shaft 22 is now rotated with the aid of the sleeve 9, the position in FIGS. 6 and 7 is produced. Here, the channels 25 in the holding sleeve 16 are located in a manner corresponding to the channels 24 in the rotary shaft 22. Therefore, the water flows past the outer side of the outlet element 19.

(23) In the position illustrated in FIG. 2, the water flows through the outlet element 19.

(24) Starting from the closed position of the valve cartridge 15, a rotation of the sleeve 9 first results in the valve cartridge opening and further rotation results in switching over between the outlet element 19 being acted upon by water, see the position in FIG. 2, and the channels 25 being acted upon, this resulting in water flowing past the outlet insert 19 to the jet outlet means 28.

(25) During this rotation of the rotary shaft 22, the outlet element 19 itself is not rotated, since it is fixed to the holding sleeve 16. If the outlet element 19 has been set in an inclined position, this being possible on account of the spherical outer side, this inclined position is retained. The position of the outlet element 19 does not change upon rotation of the sleeve 9.

(26) In the embodiment illustrated, the sleeve 9 forming the actuating element not only forms an extension of the fitting housing 1, but also has a lateral surface which is accessible for a user to act upon along the entire length and over the entire circumference of the sleeve 9. It is also conceivable for the sleeve only to be accessible at a particular location, which a user would have to take hold of in order to rotate it. What is important is that the sleeve is mounted independently of the outlet element 19.
