    The invention relates to a device for the metered delivery of a fluid into a cistern, to which a flush actuation for flushing a toilet is assigned, with a storage container for the fluid arranged in the cistern, with a metering device comprising a float which, depending on a flushing water level in the Cistern opens or closes a discharge opening for the fluid via a lever.
    Brackets are known which are hung on the rim of a toilet bowl and which hold a cleaning, deodorising and / or disinfecting agent in solid or liquid form. During a rinsing process, part of the agent is added to the rinsing water. The application is simple, but the effect leaves something to be desired, since the distribution of funds in the bowl is not ensured.
    To improve the distribution of agents, devices for metered delivery of an agent in solid or liquid form have therefore already been proposed, which are arranged in a cistern and optionally comprise a metering device for metered delivery of a fluid into the cistern water. The dosage depends on a flushing water level in the cistern. If the rinse water level drops, the agent is added to the water. If the water level rises again, the metering is stopped. For this purpose, for example, a discharge opening for the fluid is opened or closed by means of a float-operated lever (EP 1 426 505 A2).
    Dosing devices are known from DE 102 07 753 A1 and US 2004 216 221 A1, in which the discharge opening for the fluid is opened or closed by means of a valve part arranged directly on the float.

    DE 92 15 152 U1 discloses a metering device arranged in the cistern, the metering device dispensing a defined amount of the fluid into the flushing water each time the cistern is emptied. The dosing is carried out with a dosing piston operated by a float. In a bore in the metering piston, the fluid is taken up in a defined quantity by the storage container and transferred to the cistern when the metering device is actuated.
    A disadvantage of the known devices is their susceptibility to errors or their poor metering accuracy.
    The invention is therefore based on the object of providing a device of the type described at the outset which allows a reliable, well-metered dispensing of a fluid into a rinse water.
    The invention solves this problem in that the float can be displaced in a dispensing chamber, depending on the rinse water level, between a release position that releases the dispensing opening with the lever and a closed position closing the dispensing opening with the lever, the float being coupled to the lever.
    Providing the lever, which alternately releases and closes the dispensing opening and which is coupled to the float, ensures that a closing force is ensured which allows the dispensing opening to be securely closed and avoids plugging. Since the float in the dispensing chamber can be moved between a release position and a closed position depending on the flushing water level, a well-metered dispensing of the fluid into the cistern is also ensured if the dispensing chamber and the float are dimensioned accordingly.
    It is recommended if the float is magnetically coupled to the lever by means of a magnet. The float is magnetically connected to the lever, for which purpose either the float and / or the lever is equipped with a magnet. This allows a safe and low-wear with particularly simple means
    3.11
    Coupling of float and lever. In addition, assembly and maintenance are considerably simplified as the float and lever can be easily coupled or uncoupled.
    To improve the metering accuracy, a metering chamber can be provided in the flow path of the fluid between the reservoir and the discharge opening, which is preferably connected to the reservoir via a seal. The transfer of fluid from the storage container into the metering chamber takes place, for example, via defined bores, the diameter of which is preferably adapted to the viscosity of the fluid.
    The lever closes the dispensing opening in its closed position preferably with a seal arranged between a pivot axis of the lever and the coupling to the float. The seal can either be arranged on the lever or else around the discharge opening.
    It is advisable for the dispensing chamber to be open at least in some areas at the bottom and to surround the float with play in the area of the casing adjoining the dispensing chamber floor. Since the jacket of the dispensing chamber surrounds the float with play, a defined transfer of fluid to the dispensing chamber floor is ensured.
    To improve the guidance of the float, the dispensing chamber can have a projection on the bottom against the storage container, onto which the float equipped with a corresponding blind hole is placed. It is advantageous if the float lies in the release position on the attachment head with the bottom of the blind hole in its release position that releases the discharge opening with the lever, and if the float base is spaced apart from the discharge chamber floor. This enables a defined exit of the fluid from the device.
    However, it can also be provided that the float rests on the dispensing chamber floor in its release position that releases the dispensing opening with the lever and closes the at least one opening in the dispensing chamber floor. In
    In this case, the float would form a dosing piston together with the dispensing chamber.
    In order to ensure that the lever with the float is pulled down into the release position at the appropriate rinse water level in the rinse water tank, the float can be weighted down with at least one metal plate or have a corresponding weight.
    Simple constructional relationships result when the dispensing chamber is attached to the metering chamber body which forms the metering chamber and receives the lever.
    For easy refilling of the storage container, a filling hose can belong to the storage container, the filling opening of which is arranged in the area of the cistern actuation.
    In the drawing, the subject of the invention is shown schematically, for example. Show it

    Fig. 2 shows the enlarged and partially sectioned device of Fig. 1 with the lever in the closed position and
    Fig. 3 shows a detail of the device of Fig. 2, with the lever in the release position.
    The device for the metered dispensing of a fluid 1 into a cistern 2, to which a flushing actuator 3 for flushing a toilet (not shown) is assigned, comprises a reservoir 4 for the fluid 1 arranged in the cistern 2, a metering device 6 comprising a float 5, which in FIG Depending on a flushing water level in the cistern 2, a discharge opening 7 for the fluid 1 opens or closes via a lever 8. When the rinse water level h is high, the discharge opening 7 is closed and when the rinse water level n is low.

    Depending on the rinse water level, the float 5 can be displaced in a dispensing chamber 9 between a release position which releases the dispensing opening 7 with the lever 8 and a closed position which closes the dispensing opening 7 with the lever 8. The float 5 is magnetically coupled to the lever 8 by means of a magnet 10, the magnet being arranged on the lever and the float having a soft iron-metal attachment 11.
    A metering chamber 12 is provided in the flow path of the fluid 1 between the storage container 4 and the discharge opening 7 and is connected to the storage container 4 via a seal 14 arranged on a metering chamber body 13.
    The lever 8 closes the discharge opening 7 in its closed position with a seal 16 arranged between a pivot axis 15 of the lever 8 and the magnetic coupling with the float 5. The dispensing chamber 9 is at least partially open on the bottom side, that is to say has bottom openings 17 and surrounds the float 5 with play in the area of the jacket 18 adjoining the bottom. The dispensing chamber 9 has, on the bottom side, a projection 19 projecting against the storage container 4, onto which the float 5 equipped with a corresponding blind hole 20 is placed. The float 5 lies in its release position, which releases the discharge opening 7 with the lever 8, on the attachment head with the blind hole base, and the float base is spaced apart from the discharge chamber base (FIG. 3). In addition, the float 5 is weighted down with a metal plate 21.
    The dispensing chamber 9 receiving the float 5 is attached to the metering chamber body 13 forming the metering chamber 12 and receiving the lever 8 and is preferably screwed to it. Storage container 4 and metering chamber body 13 are also screwed together.
    The reservoir 4 includes a filling hose 22, the filling opening 23 of which is arranged in the area of the cistern actuation 3.
