  • Publication number: 20120204344
    Abstract: The sanitary fitting has a control cartridge which is arranged in an end region of a fitting housing and defines a longitudinal axis (A). The control cartridge and an end, on this side, of the fitting housing are covered by a fitting cap. The fitting cap has a through-passage, through which an actuating shaft of the control cartridge is connected to an actuating lever which is arranged outside the fitting cap, said actuating shaft being pivotable about a pivot axis (B) that runs at right angles to the longitudinal axis (A). A deformable, annular covering element according to the invention is fastened by way of a first rim, facing the control cartridge, to a supporting ring arranged on the control cartridge, and engages in a sealing manner by way of a second rim around the actuating shaft or a connecting element seated thereon.

  • Publication number: 20110089355
    Abstract: The present invention relates to a sanitary fitting (10) having a fitting housing (12) and having a control cartridge (36) which is arranged in the latter. The control cartridge (36) has a control shank (52) which is pivotably mounted in the control cartridge (36). On the control shank (52) is displaceably mounted an actuating lever (22) which can be pivoted up and down between a closed position and an open position in order thus to control the water flow. Furthermore, a plate (58) is mounted at one end on the guide element (60) and at the other end on an axis of rotation (C) which is fixedly arranged with respect to the pivot axis (A) and which is parallel thereto. By means of this arrangement, during the pivoting of the actuating lever (22) from the closed position in the direction toward the open position, said actuating lever is also moved in the direction away from the control shank (52) and, in the direction of the cartridge axis (B), away from the fitting housing (12).

  • Patent number: 7850323
    Abstract: A control cartridge (20) is inserted into the fitting housing (10). Mounted on the actuating shaft (38) of said cartridge is an actuating body (42) on which the tubular actuating lever (50) is fastened. A light guiding element (52) runs through the actuating lever (50). The light source (66) in the actuating body (42) emits light that is guided to the end of the actuating lever (50) by means of the light guiding element (52).

  • Patent number: 7832428
    Abstract: Sanitary fitting comprising a basic element which is designed to be fastened to an object and has a passage defining an axis, a fitting part having a sleeve-shaped portion which in a free end region has a casing-side transverse groove, the sleeve-shaped portion reaching through the passage, being mounted in the basic element, and an annular, single-part guide clamp disposed coaxially to the axis and having a guide portion for the mounting of the fitting part in the basic element, and a latching portion for cooperation with the transverse groove configured as a ring groove. The guide clamp is fixed in the transverse groove and has between the guide portion and the latching portion a radial slot running in the peripheral direction. The latching portion protrudes radially outwards over the guide portion disposed in the passage and thereby cooperates with a mating shoulder configured on the basic element.

  • Patent number: 7810521
    Abstract: Sanitary fitting (10, 10A) with an outlet (38) and a first supply line connection (74) connected hydraulically thereto and capable of being connected to a first source of liquid, with a pilot valve arrangement (48) arranged hydraulically between the first supply line connection (74) and the outlet (38), and with a second supply line connection (76) capable of being connected to a second source of liquid. The sanitary fitting (10, 10A) also exhibits a control device (50), which is connected on the inlet side to the first and the second supply line connection (74, 76) and on the outlet side to the pilot valve arrangement (48), the pilot valve arrangement (48) being permanently connected by hydraulic means via the control device (50) to at least the first supply line connection (74) or the second supply line connection (76).

  • Patent number: 7798172
    Abstract: An internal housing for a sanitary fitting has a receiving opening for receiving a control cartridge. The receiving opening is bounded along its circumference by a wall and at its lower end by a base. In order to supply water to the control cartridge, the internal housing has an inlet opening passing through the base. A discharge opening for the discharge of the water flowing out from the control cartridge also passes through the base. In order to ensure a leak-tight transition between the internal housing and the control cartridge, an inlet seal groove open on its upper side and completely surrounding the inlet opening, and a discharge seal groove open on its upper side and completely surrounding the discharge opening are formed in the base. The inlet seal groove is for receiving an inlet seal element and the discharge seal groove is for receiving a discharge seal element that consequently bear against the internal housing and against the control cartridge.

  • Patent number: 7794095
    Abstract: A sanitary fitting includes a light-permeable water-carrying outflow pipe that has (i) an exposed end face and (ii) an input face located upstream of the exposed end face. A light source, preferably including light emitting diodes (LED), inputs light into the outflow pipe through the input face. The light emerges from the outflow pipe at the end face, and may also emerge at an exposed outer peripheral surface area of the outflow pipe. The outflow pipe has a stationary first outflow pipe piece with the input face and a rotatable second outflow pipe piece with the exposed end face.

  • Publication number: 20100224812
    Abstract: A sanitary fitting includes a fitting housing; a cartridge disposed in a recess of the fitting housing, the cartridge having a control arm which, for an adjustment of a temperature of water, is rotatable about a rotation axis of the cartridge and, for an adjustment of water flow, is pivotable about a pivot axis running at right angles to the rotation axis, between an off setting and a maximum setting; an actuating lever disposed on the control arm, the actuating lever rotating and pivoting the control arm; and a cap covering the recess and the cartridge, the cap limiting a pivot motion of the actuating lever, and thus of the control arm, between the off setting and the maximum setting in an economy setting.

  • Publication number: 20100213398
    Abstract: The sanitary fitting has an outflow pipe and a mounting base. The outflow pipe is arranged galvanically isolated from the mounting base and serves as the electrode of a sensor device. The sensor device detects whether an object, for example a hand, is present in a sensor zone or not and thereupon generates a presence or an absence signal. An electronic control system controls, in accordance with the presence or absence signal, a valve device, which controls a water flow. The electronic control system can also actuate light sources which illuminate the mounting base and the nozzle region.
