  • FIGS. 1 and 2 depict a sanitary single-lever washstand fitting 1 according to prior art, which consists of a chromed, cast brass body as a fitting body 3 that has been machined in a complex manner.
  • a cartridge nut 6 with a large external thread, a standard single-lever cartridge 2 is screwed in from the top at a certain torque.
  • an optic end cap 5 Over this cartridge nut 6 , there is mounted an optic end cap 5 and then the fitting handle 7 is attached to pivot 8 of single-lever cartridge 2 by means of an Allen screw.
  • On fitting body 3 are screwed two flexible inlet hoses 10 .
  • the mixed water outlet is labeled with reference sign 22 .
  • a metric stud bolt as the attachment bolt 11 , is screwed into fitting body 3 .
  • the washstand fitting 1 is attached to wash stand 4 with a spring washer 12 and a nut 13 .
  • washstand fitting 1 After installing the washstand fitting 1 , one must check the leak-tightness between single-lever cartridge 2 and fitting body 3 as well as between the inlet houses 10 and fitting body 3 .
  • the washstand fitting 1 is generally installed by hand.
  • the fitting body is a complex brass body, which is costly to manufacture and which must be sufficiently stable, i.e., thick-walled due to its accommodating function for the single-lever cartridge.
  • the fitting body can only be replaced by completely disassembling the washstand fitting.
  • the object of the invention is to develop a sanitary single-lever washstand fitting according to the generic claim of claim 1 in such a manner that the fitting body can be manufactured in a simpler and more cost-effective manner, and that on an installed washstand fitting, the fitting body can be easily replaced. In addition, installation is to be simplified overall.
  • this task is solved in that the single-lever cartridge is attached directly to the washstand and the fitting body is put over the single-lever cartridge and is attached to the single-lever cartridge.
  • the fitting body in its structure can hereby be more simply designed and be built in a more thin-walled manner since it does not have to fulfill any receiving or holding function for the single-lever cartridge. Furthermore, it can be easily replaced since it is only put over the single-lever cartridge. Installation is here also simplified.
  • the cartridge base is expanded in the axial direction of the single-lever cartridge in the direction toward the washstand and the inlet hoses are attached solely to the expanded cartridge base, wherein channels are arranged in the cartridge base to which the inlet houses are connected and that lead to the sealing disks in the single-lever cartridge.
  • the water flow thus goes from the corner valve via the inlet hoses to the expanded cartridge base and from there through the channels to the sealing disks.
  • the single-lever cartridge is installed on the cartridge base and the sealing disks and the cartridge bearing are installed on the cartridge base. Installation is thus simplified.
  • the mixed water is in contact with a part of the interior surface of the fitting body.
  • both the cold and hot water as well as the mixed water have no contact with the fitting body.
  • the interior surface of the fitting body can thereby be designed in any manner, whereby the manufacturing costs are decreased.
  • the mixed water, sealed off from the fitting body must be carried from the single-lever cartridge to the water outlet on the fitting body. There are several possibilities for doing so.
  • the mixed water outlet on the single-lever cartridge is connected to an end of a mixed water outlet pipe and the other end of the mixed water outlet pipe is connected to the water outlet on the fitting body.
  • the mixed water outlet pipe is preferably a plastic pipe and in an advantageous embodiment, it is attached to the water outlet of the fitting body by means of a snap connection.
  • On the mixed water outlet there is preferably provided an O-ring seal, into which the mixed water outlet pipe is inserted.
  • the single-lever cartridge is closed in a watertight manner in this embodiment so that except for the mixed water outlet, no mixed water can come out of the single-lever cartridge.
  • a thread for receiving an attachment bolt is arranged parallel to the axial direction of the single-lever cartridge in the cartridge base.
  • this attachment bolt By means of this attachment bolt, one can screw the single-lever cartridge to the washstand.
  • the thread is arranged in a nut that is inserted in the cartridge base.
  • the fitting handle is attached to the pivot of the single-lever cartridge.
  • FIGS. 3 to 6 depict a preferred embodiment of a sanitary single-lever washstand fitting according to the invention.
  • FIG. 7 depicts an alternative embodiment with a mixed water outlet pipe.
  • FIG. 3 depicts a single-lever washstand fitting 1 according to the invention with a fitting body 3 with a water outlet 20 and a fitting handle 7 for opening and adjusting a single-lever cartridge 2 not visible in this drawing (see FIGS. 4 to 6 ).
  • Single-lever washstand fitting 1 is attached to a washstand 4 with a mounting bolt 11 .
  • the special type of mounting is explained further below.
  • Below washstand 4 one can see inlet hoses 10 for hot and cold water.
  • single-lever washstand fitting 1 according to the invention as per FIG. 3 does not differ from a single-lever washstand fitting as per FIG. 1 according to prior art, except that water outlet 20 can be arranged further up. “Up” refers to the direction toward fitting handle 7 .
  • FIG. 4 depicts a single-lever cartridge 2 of single-lever washstand fitting 1 according to the invention and FIG. 5 depicts a longitudinal cut through this single-lever washstand fitting 1 .
  • a standard single-lever cartridge was expanded in its cartridge base 9 facing washstand 4 in such a manner that the inlet hoses 10 can be connected directly to single-lever cartridge 2 (possible connection methods: screwing; placing; snapping in; welding; pressing; adhering). Inlet hoses 10 must be sealed off from cartridge base 9 .
  • single-lever cartridge 2 according to the invention is identical to a standard single-lever cartridge according to prior art.
  • Single-lever cartridge 2 according to the invention differs from a standard single-lever cartridge according to prior art by the expanded cartridge base 9 .
  • inlet hoses 10 are attached to single-lever cartridge 2 by means of a snap connection.
  • the snap connection is configured in such a manner that inlet hoses 10 , when snapped to single-lever cartridge 2 , cannot be loosened.
  • sealing rings 14 are arranged between single-lever cartridge 2 and inlet hoses 10 .
  • a metallic stud bolt as attachment bolt 11 is also attached directly to this expanded cartridge base 9 from below (possible connection methods: screwing; placing; snapping in; welding; pressing; adhering).
  • this attachment bolt 11 single-lever cartridge 2 is attached by means of a spring washer 12 and a nut 13 (see FIG. 5 ) to washstand 4 .
  • sealing disks 14 By means of sealing disks 14 , the water flow of the pressurized water (hot and cold water) is carried directly from the expanded cartridge base 9 to the ceramic packing washers 15 in single-lever cartridge 2 .
  • Packing washers 15 and cartridge bearing 16 are installed with cartridge housing 17 on expanded cartridge base 9 and connected to each other (possible connection methods: screwing; placing; snapping in; welding; pressing; adhering). This connection must also be configured in a sealing manner.
  • Two O-rings 18 on the exterior diameter of single-lever cartridge 2 border mixed water outlet 20 and seal off fitting body 3 .
  • This single-lever cartridge 2 constitutes the water flow from the corner valves to these O-rings 18 , and can be assembled and checked for water-tightness in an automatic assembly line.
  • FIG. 6 depicts fitting body 3 , which is put over single-lever cartridge 2 and is attached with a cross-bolt 19 to single-lever cartridge 2 .
  • Fitting body 3 can be designed very simply with a small wall thickness, since it hardly has any holding function.
  • Fitting body 3 consists of cast brass and only has two sealing surfaces and is simply put over fitting cartridge 2 and secured with a cross-bolt 9 .
  • a cartridge securing nut, its installation with constant torque as well as the chromed optical plastic cap are no longer required.
  • fitting handle 7 is attached to pivot 8 of fitting cartridge 2 by means of the Allen screw.
  • single-lever cartridge 2 is attached solely to washstand 4 .
  • Fitting body 3 is put over single-lever cartridge 2 and attached solely to single-lever cartridge 2 . Fitting body 3 is not attached to the washstand as described in prior art.
