Definitions

  • the present invention relates to a sanitary fitting according to claim 1.
  • a joystick with a joint for example, from the GB 2040465 known.
  • This joystick has a tension spring, which is firmly clamped on one side, fixedly connected to the opposite end with an actuating lever and is free in the central region. The tension spring thus forms a joint for the actuating lever. It is inherent in this joystick that immediately upon application of a force to the operating lever, a corresponding deflection takes place, which increases as the force increases, based on the characteristic of the selected compression spring. However, this has the consequence that in the region of a neutral position, the relatively lowest force to achieve a deflection is applied, and already an unintentional contact to a deflection and consequently can lead to an output signal.
  • an at least approximately planar contact surface is defined by a support structure receiving a joint arrangement, on which a joint part rests as part of the joint arrangement with its at least approximately flat counter surface, whereby a clear neutral position is defined.
  • the system is ensured by means of a compression spring which clamps it against the support stub.
  • an external force greater than a certain limit force must be applied to the extremity. This force forms a moment about a moment pole, this in turn causes a lifting of the counter surface of the contact surface except the area with the moment pole.
  • the moment pole always lies in that radially outermost point of the circumferential limit of the first mating surface against which the least resistance moment counteracts.
  • the limit force and the limit torque are dependent on the preload force of the compression spring and the prevailing geometric conditions. In a special case, if the force acts coaxially to the neutral axis, a full-surface lifting of the counter surface would be conceivable.
  • the moment pole would lie at infinity, the force would correspond exactly to the spring force and would now depend only on the spring rate, but not on the geometric conditions, a targeted deflection would not be possible.
  • the angle occupied by the mating surface to the contact surface corresponds to the angle that takes the limb to its neutral position.
  • the extremity is designed as an operating lever.
  • the deflection of the joint arrangement and thus of the actuating lever from the neutral position is detected by means of a sensor.
  • the actuating lever by the geometric design of the hinge assembly, given by resistance preferred deflection directions, so that the operator preferably performs this.
  • the operating lever is secure against rotation.
  • the compression spring is designed as a spiral spring, as this type of spring cost and far is widespread and maintenance-free, has a virtually unlimited life, and in the present case can be introduced spatially saving space due to the existing geometry specifications. In addition, it offers the possibility to realize exactly adapted spring properties and to ensure easy interchangeability.
  • the support stub which is in solid geometric connection with the contact surface, defines a longitudinal axis, which preferably extends at right angles to the abutment surface and preferably forms the neutral axis for the neutral position of the joint arrangement and form a space-saving solution in this preferred form.
  • an elastic gasket which protects the joint from environmental influences in each layer and allows only the extremity to protrude into the external environment.
  • the mechanical part of the sanitary fitting is divided into two structural units, one unit serving the operation and the second unit takes over the water supply.
  • the control unit as an electromechanical joystick and the water-carrying part designed as a discharge unit. Any other components, such as mixing devices or an electronic control, can be accommodated in separate units.
  • the senor consists of individual, arranged on a housing-fixed board Hall sensors, which interact with a magnet which is rigidly connected to the first hinge part.
  • the user can display the status of the sanitary fitting by means of a light signal at the free end of the actuating lever become.
  • the outlet pipe is as slim as possible and thus thin-walled.
  • the outlet pipe becomes more susceptible to damage due to unintentional mechanical impact loads. This can lead to damage such as bending or buckling in rigid mounting of the outlet pipe relative to its environment, preferably at the Einspannort where a shock force generates the greatest moment.
  • the discharge unit contains in the interior of its carrier nozzle, which is in a fixed connection with the environment and forms the base body, an inventive hinge assembly. The limb connected to the joint assembly is formed by the spout. On the input side, this is connected to a mixed water line.
  • connection part is advantageously mounted on the underside of the joint part and fluidly connected to the outlet pipe.
  • This connection part in turn protrudes from the underside of the support tube.
  • the sanitary fitting has in a preferred embodiment of the outlet unit on an annular centering disc, which is introduced between a stop surface and the counter surface of the second joint part and has a damping effect on pivotal movements of the outlet pipe.
  • the outlet pipe may be rotatably mounted in the second joint part.
  • the sanitary fitting in the outlet unit has a light source, preferably an LED, whose light illuminates the water jet in the outlet pipe at the outlet.
  • a light source preferably an LED, whose light illuminates the water jet in the outlet pipe at the outlet.
  • an additional light guide is present in the outlet pipe, which reduces scattering losses of the emitted light in the outlet pipe.
  • inventive sanitary fitting 10 relates to a particularly preferred embodiment of a washbasin fitting. It consists of an operating unit 12 in the form of a joystick, a water-conducting outlet unit 14, an electronic controller 16, which is preferably integrated in the control unit 12, a mixing valve unit 18 with a mixing water line 20 connected on the output side and an electrical connection line 22 between the electronic control 16 and the mixing valve unit 18, wherein the washbasin fitting for mounting in a known manner to a table top 24 is provided.
  • the operating unit 12 preferably allows the user to steplessly select the water temperature by deflecting a preferably lever-like limb 26 in a first main plane and to select the amount of water by operating this limb 26 in a second main plane, preferably at right angles to the first main plane. It is possible, by deflection in each further level between these two main levels, each set different combinations of water temperature and water quantity.
  • the operating unit 12 converts the user's choice into electrical signals, which are converted by the electronic control 16 into control signals for the mixing valve unit 18, to which a cold and a hot water supply line 28 are connected on the input side and the mixing water line 20 is connected on the output side, which directly connected to the outlet unit 14 at the input side is.

  • the first joint part 68 defines a joint part axis 78, which coincides in its neutral position with the neutral axis 38.
  • the first bore portion 54 of the stepped through bore 50 of the disc nut 50 forms a Joystickauflager 82 for the first joint part 68, consisting of the contact surface 60 and a neutral axis 38 coaxial, circular cylindrical inner side wall 86, which takes over the function of the radial stop for the joint part.
