The bolt-shaped centering or guide elements 3.3 are at the back of the mounting frame 3 slightly more than the clip elements 3.2.

Die an dem Befestigungsrahmen 3 einteilig angeformten Clipelemente 3.2 bestehen aus federelastischen Rastzungen 3.21, 3.22. Je ein Paar der Rastzungen 3.21, 3.22, die zwischen sich einen Spalt begrenzen, wird in die im wesentlichen rechteckigen Durchbrüche 1.6 eingesteckt. Die Rastzungen 3.21, 3.22 weisen nasenförmige Vorsprünge 3.23, 3.24 auf, die an ihren Enden, dem Spalt abgewandt ausgebildet sind und im montierten Zustand des Befestigungsrahmens 3 gegenüberliegende Kanten des zugeordneten Durchbruchs 1.6 hintergreifen. Jeder der nasenförmigen Vorsprünge 3.23, 3.24 weist dabei zwei schräg verlaufende Flanken auf, von denen die eine Flanke zum freien Ende der Rastzunge 3.21 bzw. 3.22 hin abfällt, während die andere Flanke zum Steg des Befestigungsrahmens 3 hin abfällt.The integrally formed on the mounting frame 3 clip elements 3.2 consist of resilient locking tongues 3.21, 3.22. Depending on a pair of locking tongues 3.21, 3.22, which define a gap between them, is inserted into the substantially rectangular openings 1.6. The locking tongues 3.21, 3.22 have nose-shaped projections 3.23, 3.24, which are formed at their ends facing away from the gap and engage behind in the mounted state of the mounting frame 3 opposite edges of the associated aperture 1.6. Each of the nose-shaped projections 3.23, 3.24 in this case has two obliquely extending flanks, one of which slopes down to the free end of the latching tongue 3.21 or 3.22, while the other flank drops to the web of the mounting frame 3 out.

Die Rastzungen 3.21, 3.22 und ihre Vorsprünge 3.23, 3.24 sind so bemessen und in Bezug auf die Kanten des zugeordneten Durchbruchs 1.6 angeordnet, dass die mit dem Befestigungsrahmen 3 hinterklebte Glasplatte 2 im montierten Zustand dicht und unter Spannung an dem Flansch 1.1 des Grundrahmens 1 anliegt.The locking tongues 3.21, 3.22 and their projections 3.23, 3.24 are dimensioned and arranged with respect to the edges of the associated aperture 1.6, that the glued behind the mounting frame 3 glass plate 2 in the mounted state tightly and under tension against the flange 1.1 of the base frame 1 ,

Der Befestigungsrahmen 3 weist ferner einen bügelförmigen Mittelsteg 3.4 auf, der sowohl an dem rückseitig vorspringenden Kragen 3.5 als auch über Stegabschnitte 3.6 an den Stegen oder Flanschen 3.1 des Befestigungsrahmens 3 einteilig angeformt sind. Durch die Stegabschnitte 3.6 und den daran angeformten bügelförmigen Mittelsteg 3.4 besitzen die Flansche (Stege) 3.1 des Befestigungsrahmens 3 eine hohe Biegesteifigkeit. Die in einer gemeinsamen Ebene liegenden Vorderseiten der Flansche 3.1 sind mit der Rückseite 2.2 der Glasplatte 2 verklebt.The mounting frame 3 further comprises a bow-shaped central web 3.4, which are integrally formed both on the rear projecting collar 3.5 and via web sections 3.6 to the webs or flanges 3.1 of the mounting frame 3. By the web sections 3.6 and the molded thereon bow-shaped central web 3.4, the flanges (webs) 3.1 of the mounting frame 3 have a high bending stiffness. The lying in a common plane front sides of the flanges 3.1 are glued to the back 2.2 of the glass plate 2.

Das die Steuerung 4 beinhaltende Gehäuse 5 ist zwischen dem Kragen 3.5 und dem bügelförmigen Mittelsteg 3.4 des Befestigungsrahmens 3 angeordnet. Die Steuerung 4 ist mit einem Stromversorgungskabel 4.1 und einem Steuerleitungen enthaltenden Kabel 4.2 versehen, wobei letzteres mit einem Stellantrieb (nicht gezeigt) verbunden wird, der ein Ablaufventil des Spülkastens betätigt.The controller 4 containing housing 5 is disposed between the collar 3.5 and the bow-shaped central web 3.4 of the mounting frame 3. The controller 4 is provided with a power supply cable 4.1 and a control line containing cable 4.2, the latter being connected to an actuator (not shown) which actuates a drain valve of the cistern.

Die an der Steuerung 4 angeschlossenen Sensortasten sind in die mit der Glasplatte 2 verklebten Vorderseite 5.1 des Gehäuses 5 eingebettet.The sensor keys connected to the controller 4 are embedded in the bonded to the glass plate 2 front 5.1 of the housing 5.

Jede der beiden Sensortasten umfasst zwei metallisch leitende Schichten eines Kondensators, die voneinander getrennt und im wesentlich in der gleichen Ebene angeordnet sind. Die eine metallisch leitende Schicht des Kondensators ist dabei über eine Impedanz mit einem Impulsgenerator verbunden, der Rechteckimpulse abgibt. Die andere metallisch leitende Schicht des Kondensators ist über eine weitere Leitung mit einem Differential-Komparator verbunden. Ein weiterer Eingang des Komparators liegt an einer definierten Spannung. Am Ausgang des Komparators liegt eine Signalspannung einer bestimmten Form. Nähert sich nun ein Benutzer mit einem seiner Finger der jeweiligen Sensortaste, so ändert sich aufgrund der veränderten Verhältnisse (Kapazitanz) die Form des Signals am Ausgang des Komparators. Da der Komparator das Signal an seinem Eingang mit einer konstanten festen Bezugsspannung vergleicht, verändert sich bei Annäherung des Fingers des Benutzers an die Sensortaste die Impulsbreite der Impulszüge am Ausgang des Komparators. Bei Berühren der Glasplatte 2 vor der dahinter angeordneten Sensortaste werden die Impulse am Ausgang des Komparators schmaler. Die Änderung des Signals wird dann zur Auslösung eines Steuerungsvorgangs bzw. Spülvorgangs verwendet.Each of the two sensor keys comprises two metallically conductive layers of a capacitor, which are separated from each other and arranged substantially in the same plane. The one metallically conductive layer of the capacitor is connected via an impedance with a pulse generator which emits rectangular pulses. The other metallically conductive layer of the capacitor is connected via a further line to a differential comparator. Another input of the comparator is at a defined voltage. At the output of the comparator is a signal voltage of a certain shape. If a user approaches the respective sensor key with one of his fingers, the shape of the signal at the output of the comparator changes due to the changed conditions (capacitance). Since the comparator compares the signal at its input with a constant, fixed reference voltage, as the user's finger approaches the sensor key, the pulse width of the pulse trains at the output of the comparator changes. Upon touching the glass plate 2 in front of the sensor button arranged behind it, the pulses at the output of the comparator become narrower. The change in the signal is then used to trigger a control action or purging process.

Auf der Vorderseite 2.1 der Glasplatte 2 sind Symbole 2.3, 2.4 angebracht oder aufgetragen, beispielsweise aufgedruckt, die für unterschiedliche Spülwassermengen oder Ablaufventil-Funktionen stehen. Die Sensortasten sind hinter den Symbolen 2.3, 2.4 an der Rückseite 2.2 der Glasplatte 2 angeordnet.On the front 2.1 of the glass plate 2 symbols 2.3, 2.4 are attached or applied, for example, printed, which are available for different Spülwassermengen or drain valve functions. The sensor keys are arranged behind the symbols 2.3, 2.4 at the rear 2.2 of the glass plate 2.

Die Steuerung 4 ist so ausgelegt, dass durch Annäherung oder Anordnung eines Fingers eines Benutzers an eine der beiden Sensortasten eine Vollspülung ausgelöst wird. Dieser Sensortaste ist das größere (2.3) der beiden Symbole auf der Vorderseite der Glasplatte 2 zugeordnet. Durch entsprechende Einwirkung auf die andere Sensortaste wird dagegen eine Teilspülung ausgelöst; dieser Sensortaste ist das kleinere Symbol 2.4 auf der Glasplatte 2 zugeordnet.The controller 4 is designed so that a full flush is triggered by approaching or placing a user's finger on one of the two sensor keys. This sensor key is associated with the larger (2.3) of the two symbols on the front of the glass plate 2. By appropriate action on the other sensor key, however, a partial flush is triggered; this sensor key is associated with the smaller symbol 2.4 on the glass plate 2.

Die Steuerung 4 der erfindungsgemäßen Vorrichtung kann allerdings auch so ausgelegt sein oder wahlweise eingestellt werden, dass sie eine Spül-Stopp-Funktion ermöglicht. In diesem Fall wird durch Annäherung oder Anordnung eines Fingers eines Benutzers an eine der beiden Sensortasten ein Spülvorgang ausgelöst, und durch entsprechende Einwirkung auf die andere Sensortaste der Spülvorgang gestoppt.However, the controller 4 of the device according to the invention may also be designed or optionally set to allow a rinse-stop function. In this case, by approaching or placing a finger of a user to one of the two sensor keys, a flushing process is triggered, and stopped by appropriate action on the other sensor button flushing.
