  • Patent number: 8991728
    Abstract: A plumbing outlet armature (2) with a liquid guide (3), which opens into a fitting outlet (4) in an area in which a plumbing functional unit (5) in the form of an insertion cartridge is provided. The outlet fitting is provided such that the clear open cross-section of the liquid guide (3) is adapted to the insertion cartridge (5) at least in the opening area of the fitting outlet (4), and the insertion cartridge (5) can be inserted into the fitting outlet (4) from the opening side and is removably held therein. The inventive outlet armature is characterized by the insertion cartridge being removably held in the fitting outlet (4) by a sleeve-shaped intermediate holder (6), which intermediate holder itself is removably held in the fitting outlet (4) by a screw or bayonet connection. The inventive outlet fitting (2) can be used with a jet regulator or with another plumbing functional unit (5) without any significant limitations of the structural clearance.

  • Publication number: 20140217203
    Abstract: A sanitary insert, which is arranged in a water line, is provided. The sanitary insert includes a mixing device with at least one throttling or closing element, which can be moved under the pressure of the inflowing water from a mixing or open position into a throttling or closed position against a restoring force. The mixing device offers a relatively large clear flow cross section when the at least one throttling or closing element in the mixing or open position, and, by contrast thereto, a reduced clear flow cross section when the at least one throttling or closing element is in the throttling or closed position. The installation element always offers an optimum flow cross section both in low and high pressure ranges.

  • Patent number: 8746596
    Abstract: A manual spray head can be connected with a flexible hose line by means of a coupling that has a ball-and-socket joint inserted between the manual spray head and the hose line. This arrangement not only increases the mobility and flexibility between the manual spray head and the flexible hose line, but also permits twisting of the manual spray head relative to the hose line without fear of unscrewing the screw-type connection or similar coupling provided between the manual spray head and the hose line.

  • Patent number: 8740112
    Abstract: A sanitary functional unit with a housing releasably fastened to the water outlet of a sanitary outlet fitting, the housing having an outflow-side housing end face with outflow openings. The outflow-side housing end face has at least one slot, opposing longitudinal sides of which form turning engagement surfaces or tool engagement surfaces for a turning tool that is releasably inserted into the slot, and the housing of the functional unit is rotatably held on the water outlet of the outlet fitting and/or the housing end face is mounted rotatably in the housing. Using the turning tool in the slot, a pivotably mounted housing end face in the housing can be easily aligned and/or the turning force required for fitting and removing a screw connection provided between the outer housing periphery and the inner fitting periphery can be conveniently transferred to the housing without requiring special turning tools.

  • Publication number: 20130088007
    Abstract: A water outlet fitting with a handleable water outlet (4) and with a flexible hose line (3) which can be connected to the water outlet (4) via a coupling (5). A characteristic feature of the water outlet fitting according to the invention is that the coupling (5), which is provided for connecting the water outlet (4) and hose line (3), has a ball-and-socket joint (7). The ball-and-socket joint (7) connected between the water outlet (4) and the hose line (3) not only increases the mobility and articulation between the water outlet (4) and the flexible hose line (3), but the ball-and-socket joint (7) also permits the water outlet (4) to be rotated relative to the hose line (3) without having to be concerned that the screw connection or similar coupling (5) provided between the water outlet (4) and hose line (3) will become undone.

  • Patent number: 8342429
    Abstract: A sanitary outlet fitting with a liquid guide which opens into an outlet fitting, in the region of which an insertable cartridge is provided. The liquid guide is matched in at least the mouth region of the outlet fitting to the insertable cartridge. The insertable cartridge is held in the outlet fitting by a sleeve-shaped intermediate holder, which is held in the outlet fitting in a radially sealed manner. A peripheral edge region on the admission side of the insertable cartridge is held in an axially sealed manner in the outlet fitting. The insertable cartridge is inserted with the aid of the intermediate holder supporting it into the outlet fitting to a depth such that the insertable cartridge is held securely. Accordingly, the insertable cartridge is scaled axially in its peripheral region on the admission side. The intermediate holder can also be held in a radially sealed manner in the outlet fitting to prevent undesired creepage.
