At least two energy accumulators (2a, 2b) are used to impinge the actuating element (3) and the number of the energy accumulators (2a, 2b) impinging the actuating element (3) varies in predetermined positions (S1, S2) of the trajectory (S).

Description

Die vorliegende Erfindung betrifft ein Schaltelement mit einem durch einen Kraftspeicher beaufschlagbaren und über eine vorgegebene Strecke bewegbar gelagerten Betätigungselement, eine Antriebsvorrichtung für ein bewegbares Möbelteil mit einer Steuer- bzw. Regeleinrichtung sowie ein Möbel mit einem bewegbaren Möbelteil und einer derartigen Antriebsvorrichtung.The present invention relates to a switching element with an actuatable by a force storage and movably mounted over a predetermined distance actuator, a drive device for a movable furniture part with a control or regulating device and a piece of furniture with a movable furniture part and such a drive device.

Solche Schaltelemente kommen beispielsweise derart zum Einsatz, dass das bewegbare Möbelteil in seiner Schließlage am Betätigungselement anliegt, wodurch eine Zug- oder Druckausübung auf das Möbelteil durch einen Benutzer eine Bewegung des Betätigungselements zur Folge hat.Such switching elements are used for example in such a way that the movable furniture part rests in its closed position on the actuating element, whereby a tensile or pressure on the furniture part by a user has a movement of the actuating element result.

Beispielsweise ist es bekannt, den Kraftspeicher als Druckfeder auszubilden und das Betätigungselement derart zum Kraftspeicher anzuordnen, dass es bei einem Möbelteil in der Schließlage durch das am Betätigungselement anliegende Möbelteil um eine Teilstrecke der gesamten vorgegebenen Strecke gegen die Beaufschlagung der Druckfeder eingedrückt wird. Übt nun ein Benutzer Druck auf das Möbelteil in der Schließlage aus (hiefür muss natürlich auch in der Schließlage des Möbelteils ein entsprechendes Spiel für die Bewegung des Möbelteils vorgesehen sein) so wird das Betätigungselement weiter gegen die Beaufschlagung der Druckfeder bewegt. Dies kann entweder durch eine die Bewegung des Betätigungselements überwachende Sensoreinrichtung oder über geeignet angeordnete Schalter detektiert werden, woraufhin die Auslösung einer Antriebsvorrichtung für das Möbelteil erfolgt.For example, it is known to form the energy accumulator as a compression spring and to arrange the actuating element to the energy storage that it is pressed in a closed part by a furniture part in the closed position by the part lying on the actuating element to a portion of the entire predetermined distance against the application of the compression spring. Now exerts a user pressure on the furniture part in the closed position (of course, must be provided in the closed position of the furniture part a corresponding game for the movement of the furniture part) so the actuator is further moved against the action of the compression spring. This can be detected either by a sensor device monitoring the movement of the actuating element or by suitably arranged switches, whereupon the triggering of a drive device for the furniture part takes place.

Übt der Benutzer hingegen eine Zugkraft auf das Möbelteil in der Schließlage aus, führt er also zum Beispiel eine Schublade etwas aus dem Möbelkorpus heraus oder hebt er eine Klappe etwas vom Möbelkorpus ab, so führt dies dazu, dass das Betätigungselement aufgrund der Kraftbeaufschlagung durch die Druckfeder über eine Teilstrecke der vorgegebenen Strecke dem Möbelteil folgt, was ebenfalls durch eine die Bewegung des Betätigungselements überwachende Sensoreinrichtung oder geeignete Schalter detektiert und für die Auslösung einer Antriebsvorrichtung des Möbelteils verwendet werden kann.The user, however, exerts a tensile force on the furniture part in the closed position, so he leads, for example, a drawer something out of the furniture carcass or he lifts a flap something from the furniture body, this will cause the actuator due to the application of force by the compression spring over a section of the predetermined distance follows the furniture part, which also detected by a movement of the actuating element monitoring sensor device or suitable switch and can be used for triggering a drive device of the furniture part.

Nachteilig an einem derartigen Schaltelement ist die Tatsache, dass die Neutralposition (keine Auslösung der Antriebsvorrichtung) des Betätigungselements, in welcher sich das Möbelteil in seiner Schließlage befindet, relativ schlecht definiert ist und im Wesentlichen über die vorgegebene Strecke überall auf der Kennlinie des Kraftspeichers liegen kann. Damit verbunden ist auch ein verringerter Bedienkomfort, da es von den meisten Benutzern als angenehm empfunden wird, wenn das Schaltelement bei einem genau definierten Schaltpunkt auslösbar ist.A disadvantage of such a switching element is the fact that the neutral position (no triggering of the drive device) of the actuating element, in which the furniture part is in its closed position, is relatively poorly defined and can lie substantially on the predetermined distance anywhere on the characteristic of the energy storage , This is associated with a reduced ease of use, since it is perceived by most users as pleasant when the switching element is triggered at a well-defined switching point.

Dabei kann es genügen nur zwei Kraftspeicher vorzusehen, sodass innerhalb der Strecke, über welche sich das Betätigungselement bewegen kann, nur eine vorgegebene Position und damit ein einziger definierter Schaltpunkt realisiert ist.By the factory choice of the predetermined positions along the route over which the actuator can move, the desired switching points can be predefined. It may be sufficient to provide only two energy storage, so that within the route over which the actuator can move, only a predetermined position and thus a single defined switching point is realized.

Erfindungsgemäß kommt ein Schaltelement in einer Antriebsvorrichtung für ein bewegbares Möbelteil zum Einsatz, wobei die Steuer- bzw.

Beispielsweise kann auch eine drahtlose Signalübertragung durch Funk oder Infrarotstrahlung vorgesehen sein.According to the invention, a switching element is used in a drive device for a movable furniture part, wherein the control or regulating device of the drive device is connected to an interface or electrical lines of the switching element. The term interface is to be interpreted broadly. For example, a wireless signal transmission by radio or infrared radiation may be provided.

Regeleinrichtung versehen, die mit einer Schnittstelle oder elektrischen Leitungen eines Schaltelements verbunden ist, und mit einem durch die Steuer- bzw. Regeleinrichtung auslösbaren Elektromotor zum Antreiben des Möbelteils, wobei das Schaltelement ein über eine Strecke bewegbar gelagertes Betätigungselement aufweist, das durch einen eine Kennlinie aufweisenden Kraftspeicher beaufschlagbar ist und wobei das Schaltelement durch Bewegen des Betätigungselements zu einem Schaltpunkt den Elektromotor über die Steuer- bzw. Regeleinrichtung auslöst, wobei zur Beaufschlagung des Betätigungselements wenigstens zwei Kraftspeicher vorgesehen sind und wobei sich die Anzahl der das Betätigungselement beaufschlagenden Kraftspeicher an vorgegebenen Positionen der Strecke (S) ändert, wodurch sich die Steigung der Kennlinie an diesen Positionen ändert, von welchen Positionen eine im Inneren der Strecke liegende Position als Schaltpunkt des Schaltelements ausgebildet ist.The drive device is provided with a control or regulating device, which is connected to an interface or electrical lines of a switching element, and with an actuatable by the control or regulating device electric motor for driving the furniture part, wherein the switching element is a movably mounted over a distance Has actuating element, which is acted upon by a characteristic having a power storage and wherein the switching element by moving the Actuating element to a switching point triggers the electric motor via the control or regulating device, wherein at least two force accumulators are provided for acting on the actuating element and wherein the number of the actuator acting force accumulator at predetermined positions of the distance (S) changes, causing the slope of the Characteristic changes at these positions, from which positions a position lying in the interior of the track is formed as a switching point of the switching element.

Eine derartige Antriebsvorrichtung eignet sich besonders zum Einsatz in einem Möbel, bei dem das Möbelteil in seiner Schließstellung am Betätigungselement des Schaltelements anliegt, wodurch sich die Möglichkeit ergibt, die Antriebsvorrichtung des Möbelteils durch Eindrücken des Möbelteils bis zum definierten Schaltpunkt oder durch Ziehen am Möbelteil auszulösen.Such a drive device is particularly suitable for use in a piece of furniture in which the furniture part rests in its closed position on the actuating element of the switching element, whereby the possibility arises to trigger the drive device of the furniture part by pressing the furniture part to the defined switching point or by pulling the furniture part.

Die Erfindung macht sich die Tatsache zunutze, dass es bei der Anordnung wenigstens zweier Kraftspeicher 2a, 2b zur Beaufschlagung des Betätigungselements 3 möglich ist, durch das Vorgeben einer Position S2 einen definierten Schaltpunkt für das Schaltelement 1 festzulegen, indem die Anzahl der das Betätigungselement beaufschlagenden Kraftspeicher 2a, 2b geändert wird.The invention takes advantage of the fact that it is possible in the arrangement of at least two energy storage 2a, 2b for acting on the actuating element 3, by specifying a position S 2 set a defined switching point for the switching element 1 by the number of acting on the actuator Power storage 2a, 2b is changed.

Eine erste Position S1 befindet sich beispielsweise zu Beginn der vom Betätigungselement 3 zurücklegbaren Strecke S, das heißt, wenn das Betätigungselement 3 voll ausgefahren ist und durch keinen der Kraftspeicher 2a, 2b beaufschlagt wird. Diese Position S1 ist allerdings meistens für die Erfindung von untergeordneter Bedeutung, da sich im Montagezustand des Schaltelements 1 in bzw. an einem Möbel das Möbelteil 8 in diesem Fall außerhalb seiner Schließstellung befindet. Beispielsweise wird diese Position durch das Betätigungselement 3 eingenommen, wenn das Möbelteil 8 durch einen Benutzer vom Möbelkorpus abgehoben wurde und anschließend durch eine Antriebsvorrichtung 9 weiter vom Möbelkorpus wegbewegt wurde. In dieser Position S1 verbleibt das Betätigungselement 3 so lange bis das Möbelteil 8 wieder zur Anlage an das Betätigungselement 3 kommt. In diesem Fall ist das Möbelteil 8 allerdings üblicherweise mit einem derart großen Impuls ausgestattet, dass es sich entweder von selbst oder durch die Kraftbeaufschlagung einer Einzugsvorrichtung in die Schließlage bewegt, sodass der Benutzer den ersten definierten Schaltpunkt bei Position S1 meist nicht weiter bemerkt.A first position S 1 is located, for example, at the beginning of the traversable by the actuator 3 distance S, that is, when the actuator 3 is fully extended and by none of the energy storage 2a, 2b is applied. However, this position S 1 is mostly of minor importance for the invention, since in the assembled state of the switching element 1 in or on a piece of furniture, the furniture part 8 is in this case outside its closed position. For example, this position is occupied by the actuating element 3, when the furniture part 8 has been lifted by a user from the furniture body and was then moved away by a drive device 9 further from the furniture body. In this position S 1 , the actuating element 3 remains until the furniture part 8 again comes to bear against the actuating element 3. In this case, however, the furniture part 8 is usually equipped with such a large impulse that it moves either by itself or by the application of force to a collection device in the closed position, so that the user usually not notice the first defined switching point at position S 1 .

Dies ist allerdings anders, wenn vorgesehen ist, dass die Antriebsvorrichtung 9 für das Möbelteil 8 auch dann durch das Schaltelement 1 auslösbar bleibt, wenn sich das Möbelteil 8 außerhalb seiner Schließlage befindet. Dies ist zum Beispiel dann besonders sinnvoll, wenn das Möbelteil 8 als Klappe ausgebildet ist, da sich eine geöffnete Klappe in einer relativ hohen Stellung befindet und es für einen Benutzer bequemer sein kann, das Schließen des Möbelteils durch Betätigung des Betätigungselements 3 des Schaltelements 1 auszulösen.However, this is different if it is provided that the drive device 9 for the furniture part 8 is then triggered by the switching element 1, when the furniture part 8 is outside its closed position. This is particularly useful, for example, when the furniture part 8 is designed as a flap, as it is an open flap in a relatively high position and it may be convenient for a user to trigger the closing of the furniture part by actuation of the actuating element 3 of the switching element 1 ,

Von größerer Bedeutung ist allerdings jener definierte Schaltpunkt, welcher bei Position S2 der Strecke S dadurch realisiert wird, dass sich die Anzahl der das Betätigungselement 3 beaufschlagenden Kraftspeicher 2a, 2b von eins auf zwei erhöht. Mit anderen Worten ist in diesem Ausführungsbeispiel vorgesehen, dass das Betätigungselement 3 zwischen den Position S1 und S2 nur durch den ersten Kraftspeicher 2a gegen ein Eindrücken beaufschlagt wird und erst bei Position S2 der zweite Kraftspeicher 2b ebenfalls das Betätigungselement 3 beaufschlagt.Of greater importance, however, is that defined switching point which is realized at position S 2 of the distance S by the number of force actuators 2 a, 2 b acting on the actuating element 3 increasing from one to two. In other words, it is provided in this embodiment that the actuating element 3 between the position S 1 and S 2 only by the first Force memory 2a is acted upon against impressions and only at position S 2 of the second energy storage 2b also applied to the actuator 3.

Vorzugsweise ist dabei vorgesehen, dass der erste Kraftspeicher 2a bei der Position S2 bereits seine Maximalkraft erreicht hat. Ist der Kraftspeicher beispielsweise als Druckfeder ausgebildet, so bedeutet dies, dass sich die Druckfeder in dieser Position nicht weiter komprimieren lässt, sodass die vom Kraftspeicher 2a ausgeübte Kraft ab dieser Position konstant bleibt.Preferably, it is provided that the first energy storage 2a has already reached its maximum force at the position S 2 . If the energy accumulator is designed, for example, as a compression spring, this means that the pressure spring can not be further compressed in this position, so that the force exerted by the force accumulator 2a remains constant from this position.

Weisen die wenigstens zwei Kraftspeicher 2a, 2b verschieden steile Kennlinien (d.h. die von ihnen ausgeübte Kraft F aufgetragen über die Strecke S) auf, so ergibt sich der definierte Schaltpunkt als Kreuzungspunkt der Kennlinien der Kraftspeicher 2a, 2b bei der Position S2 (siehe Fig.6a, 6b).Assign the at least two energy storage 2a, 2b different steep curves (ie applied by them force F applied over the distance S), the result is the defined switching point as a crossing point of the characteristics of the energy storage 2a, 2b at the position S 2 (see Fig.6a, 6b ).

Eine besonders einfache Konstruktion des Schaltelements 1 ergibt sich, wenn vorgesehen ist, dass das Betätigungselement 3 wenigstens zwei begrenzt zueinander bewegbar gelagerte Teile 3a, 3b aufweist, wie dies beispielhaft in den Fig. 1, bis 5 dargestellt ist.A particularly simple construction of the switching element 1 results if it is provided that the actuating element 3 has at least two parts 3 a, 3 b, which are movable in a limited manner relative to one another, as shown by way of example in FIGS Fig. 1, to 5 is shown.

In beiden Fällen ist jeweils zwischen einer Lagerstelle 4, 5 und einem der wenigstens zwei Teile 3a, 3b einer der wenigstens zwei Kraftspeicher 2a, 2b, welche hier als Federn ausgebildet sind, angeordnet.In both cases, in each case between a bearing 4, 5 and one of the at least two parts 3a, 3b one of the at least two energy storage 2a, 2b, which are formed here as springs arranged.

Wie bereits ausgeführt kann es vorteilhaft sein, wenn die wenigstens zwei Kraftspeicher 2a, 2b verschieden steile Kennlinien aufweisen. Hierdurch ist es möglich, den einen Kraftspeicher 2a beispielsweise sehr viel schwächer auszuführen, als den anderen Kraftspeicher 2b. Es wäre selbstverständlich aber auch denkbar, beide Kraftspeicher 2a, 2b mit derselben Kennlinie auszubilden (im Falle von Federn würde dies bedeuten, mit derselben Federkonstante).As already stated, it may be advantageous if the at least two force accumulators 2a, 2b have different steep characteristics. This makes it possible, for example, to perform the one energy storage 2a much weaker than the other energy storage 2b. Of course, it would also be conceivable to design both force accumulators 2a, 2b with the same characteristic (in the case of springs, this would mean having the same spring constant).

Zwei Beispiele für mögliche konstruktive Ausführungen des erfindungsgemäßen Schaltelements 1 seien anhand der Figuren 1 bis 5 im Detail diskutiert:

  • Erkennbar ist in Fig. 1a ein erfindungsgemäßes Schaltelement 1, von dem elektrische Leitungen 7 zur Stromversorgung des Schaltelements 1 bzw. zur Weiterleitung der Signale des Schaltelements 1 abgehen. In diesem Ausführungsbeispiel weist das Schaltelement 1 ein Gehäuse 10 auf und kann beispielsweise in einer Ecke des Möbelkorpus eines Möbels montiert werden. Das Betätigungselement 3 ist in diesem Ausführungsbeispiel von vier Leuchtelementen 11 (hier: Leuchtdioden) umgeben. Die Leuchtmittel 11 sollen einem Benutzer die Position des Schaltelements 1 anzeigen.
Two examples of possible constructive embodiments of the switching element 1 according to the invention are described with reference to FIG FIGS. 1 to 5 discussed in detail:
  • Is recognizable in Fig. 1a an inventive switching element 1, from the electrical lines 7 to the power supply of the switching element 1 and zur Weiterleitung der Signals of the switching element 1 go off. In this embodiment, the switching element 1 has a housing 10 and can be mounted, for example, in a corner of the furniture body of a piece of furniture. The actuating element 3 is surrounded in this embodiment by four light-emitting elements 11 (here: light-emitting diodes). The lighting means 11 are intended to indicate to a user the position of the switching element 1.

Die Montage des Schaltelements 1 kann über einen Montageteil 12 erfolgen.The assembly of the switching element 1 can be done via a mounting part 12.

In diesem Ausführungsbeispiel weist das Betätigungselement 3 zwei Teile 3a, 3b auf, wobei der erste Teil 3a als Stift ausgebildet ist.In this embodiment, the actuating element 3 has two parts 3a, 3b, wherein the first part 3a is formed as a pin.

Weiters sind zwei Schalter 6a, 6b erkennbar, die auf einer gemeinsamen Platine 14 angeordnet sind und deren Funktion anhand der Fig. 2 näher erläutert werden wird.Furthermore, two switches 6a, 6b can be seen, which are arranged on a common board 14 and whose function is based on the Fig. 2 will be explained in more detail.

Die Fig. 2a bis 2b zeigen dabei das Schaltelement 1 nach der Fig. 1 jeweils in einer Schnittdarstellung und einer Detaildarstellung in drei unterschiedlichen Betriebsstellungen.The Fig. 2a to 2b show the switching element 1 after the Fig. 1 each in a sectional view and a detailed representation in three different operating positions.

In Fig. 2a befindet sich das Schaltelement 1 in seiner Neutralstellung, das heißt ein nicht dargestelltes Möbelteil 8 liegt am ersten Teil 3a an und befindet sich in seiner Schließstellung. Das Schaltelement 1 ist nicht aktiviert. Erkennbar ist in der Detaildarstellung, dass mit dem ersten Teil 3a ein Schieberelement 13 (hier in Form einer Hülse ausgebildet) verbunden ist, welches derart angeordnet ist, dass es bei einer Bewegung des Betätigungselements 3 zwei Schalter 6a, 6b betätigen kann, wobei es jeweils bei einer Betätigung eines der beiden Schalter 6a, 6b zur Schließung eines elektrischen Kontaktes und zur Weiterleitung eines Schaltimpulses über die elektrischen Leitungen 7 kommt.In Fig. 2a is the switching element 1 in its neutral position, that is, a not shown furniture part 8 is applied to the first part 3a and is in its closed position. The switching element 1 is not activated. It can be seen in detail that with the first part 3a a slider element 13 (here in the form of a sleeve) is connected, which is arranged such that it can actuate two switches 6a, 6b during a movement of the actuating element 3, wherein it respectively upon actuation of one of the two switches 6a, 6b for closing an electrical contact and for forwarding a switching pulse via the electrical lines 7 comes.

Fig. 2b zeigt die Situation, wenn das bewegbare Möbelteil 8 von einem Benutzer etwas aus der Schließlage herausbewegt wurde. Hierdurch ist es dem ersten Kraftspeicher 2a möglich, den ersten Teil 3a des Betätigungselements 3 maximal aus dem Gehäuse 10 hinauszudrücken. Hierdurch wird, wie in der Detaildarstellung erkennbar, durch den Schieber 13 der vordere Schalter 6a eingedrückt und damit betätigt. In Folge kommt es über die elektrischen Leitungen 7 zum Versenden eines Auslösesignals an eine nicht dargestellte Steuer- bzw. Regeleinrichtung einer Antriebsvorrichtung und schlussendlich zur Aktivierung der Antriebsvorrichtung zum weiteren Ausstoßen des Möbelteils 8. Fig. 2b shows the situation when the movable furniture part 8 has been moved slightly out of the closed position by a user. As a result, it is possible for the first energy store 2a to push the first part 3a of the actuating element 3 out of the housing 10 to the maximum extent. As a result, as can be seen in the detailed representation, pushed by the slider 13 of the front switch 6a and thus actuated. In consequence, it comes via the electrical lines 7 for sending a trigger signal to a control or regulating device, not shown, of a drive device and Finally, to activate the drive device for further ejection of the furniture part. 8

Im Gegensatz dazu wurde in Fig. 2c das Möbelteil 8 weiter in seine Schließlage hineingedrückt. Dies hat zur Folge, dass der erste Teil 3a den zwischen dem ersten Teil 3a und einer Lagerstelle 5 angeordneten ersten Kraftspeicher 2a maximal komprimiert. In dieser Situation kontaktiert der erste Teil 3a den zweiten Teil 3b, wobei zwischen dem zweiten Teil 3b und einer Lagerstelle 4 der zweite Kraftspeicher 2b angeordnet ist. In der in Fig. 2c dargestellten Lage wurde der zweite Teil 3b bereits etwas vom ersten Teil 3a gegen die Beaufschlagung durch den Kraftspeicher 2b bewegt und der Schieber 13 hat den zweiten Schalter 6b ausgelöst. Die Fig. 2c zeigt also die Situation, in welcher das Betätigungselement 3 die Position S2 eingenommen hat, welche einen definierten Schaltpunkt darstellt. Dieser definierte Schaltpunkt liegt, wie bereits ausgeführt, beim Übergang von der Kennlinie des Kraftspeichers 2a auf jene des Kraftspeichers 2b, wie in Fig. 6a dargestellt.In contrast, in Fig. 2c the furniture part 8 is pushed further into its closed position. As a result, the first part 3a maximally compresses the first force accumulator 2a arranged between the first part 3a and a bearing 5. In this situation, the first part 3a contacts the second part 3b, wherein between the second part 3b and a bearing 4 of the second energy storage 2b is arranged. In the in Fig. 2c As shown, the second part 3b has already moved somewhat from the first part 3a against being acted upon by the energy storage device 2b and the slide 13 has triggered the second switch 6b. The Fig. 2c So shows the situation in which the actuator 3 has assumed the position S 2 , which represents a defined switching point. This defined switching point is, as already stated, the transition from the characteristic of the energy storage 2a to that of the energy storage 2b, as in Fig. 6a shown.

Die Figuren 3 bis 5 zeigen ein weiteres Ausführungsbeispiel eines erfindungsgemäßen Schaltelements 1.The FIGS. 3 to 5 show a further embodiment of a switching element 1 according to the invention.

Wie im ersten Ausführungsbeispiel weist das Schaltelement 1 ein Gehäuse 10 auf, in welchem ein Betätigungselement 3 bewegbar gelagert ist. Weiters sind über elektrische Leitungen 7 die Signale des Schaltelements 1 einer nicht dargestellten Steuer- bzw. Regeleinrichtung zuführbar bzw. dienen diese Leitungen 7 der Stromversorgung des Schaltelements 1.As in the first embodiment, the switching element 1 has a housing 10 in which an actuating element 3 is movably mounted. Furthermore, the signals of the switching element 1 of a control or regulating device, not shown, can be fed via electrical lines 7 or serve these lines 7 of the power supply of the switching element. 1

Fig. 3b zeigt eine Explosionsdarstellung des Schaltelements 1. Fig. 3b shows an exploded view of the switching element. 1

Erkennbar ist, dass das Betätigungselement 3 auch in diesem Ausführungsbeispiel zwei Teile 3a, 3b aufweist. Zwischen dem ersten Teil 3a und dem zweiten Teil 3b sind dabei an Lagerstellen 5 zwei Kraftspeicher 2a angeordnet, welche in Summe wie ein einzelner Kraftspeicher 2a arbeiten. Zwischen dem zweiten Teil 3b und der an einem an einer Platine 14 aufgesteckten Halter 4b ausgebildeten Lagerstelle 4a ist ein einzelner Kraftspeicher 2b angeordnet. An der Platine 14 sind zwei Schalter 6a, 6b angeordnet, die in diesem Ausführungsbeispiel als Kippschalter ausgebildet sind. Die Funktion der Schalter 6a, 6b wird im Detail in den Figuren 4a bis 4c erläutert.It can be seen that the actuating element 3 also has two parts 3a, 3b in this exemplary embodiment. Between the first part 3a and the second part 3b, two force accumulators 2a are arranged at bearing points 5, which work in total like a single energy accumulator 2a. Between the second part 3b and formed on a plugged onto a board 14 holder 4b bearing 4a a single energy storage 2b is arranged. On the board 14, two switches 6a, 6b are arranged, which are formed in this embodiment as a toggle switch. The function of the switches 6a, 6b will be described in detail in FIGS FIGS. 4a to 4c explained.

Die Fig. 4a zeigt die Neutralstellung des Schaltelements 1, in welcher das Schaltelement 1 keine Signale über die Leitungen 7 aussendet und sich das nicht dargestellte Möbelteil 8 in der Schließstellung befindet und den ersten Teil 3a des Betätigungselements 3 kontaktiert. In dieser Position betätigt der zweite Teil 3b den ersten Schalter 6a. Der Kraftspeicher 2b zwischen dem zweiten Teil 3b und der Lagerstelle 4a ist maximal komprimiert und der zweite Teil 3b und der Halter 4b sind auf Anschlag aneinander gefahren. Wie bereits gesagt, stellt die in Fig. 4 dargestellte Situation den Neutralzustand des Schaltelements 1 dar, obwohl der zweite Teil 3b den ersten Schalter 6a betätigt. Dies wird anhand der nachfolgenden Figuren besser verständlich.The Fig. 4a shows the neutral position of the switching element 1, in which the switching element 1 emits no signals via the lines 7 and the furniture part 8, not shown, is in the closed position and the first part 3a of the actuating element 3 contacted. In this position, the second part 3b actuates the first switch 6a. The energy storage 2b between the second part 3b and the bearing 4a is compressed to the maximum and the second part 3b and the holder 4b are driven against each other. As already said, the in Fig. 4 illustrated situation, the neutral state of the switching element 1, although the second part 3b, the first switch 6a is actuated. This will be better understood with reference to the following figures.

Fig. 4b zeigt die Situation, in welcher das Möbelteil 8 vom Benutzer etwas aus der Schließlage herausbewegt wurde. Hierdurch können sich der zweite Teil 3b und damit der erste Teil 3a unter der Kraftbeaufschlagung durch den Kraftspeicher 2b maximal aus dem Gehäuse 10 herausbewegen. Erkennbar ist, dass der zweite Teil 3b den ersten Schalter 6a in dieser Situation nicht mehr betätigt. Genau dieser Übergang von Betätigung zu Nichtbetätigung des ersten Schalters 6a liefert den Schaltimpuls, welcher die Antriebsvorrichtung aktiviert und das Möbelteil 8 weiter ausstößt. Fig. 4b shows the situation in which the furniture part 8 has been moved slightly out of the closed position by the user. As a result, the second part 3b, and thus the first part 3a, can move out of the housing 10 as much as possible under the application of force by the energy store 2b. It can be seen that the second part 3b no longer actuates the first switch 6a in this situation. Exactly this transition from actuation to non-actuation of the first switch 6a provides the switching pulse, which activates the drive device and the furniture part 8 continues to expel.

Fig. 4c zeigt die Situation, in welcher das Möbelteil 8 durch den Benutzer aus der Schließlage weiter in den Möbelkorpus hineinbewegt wurde. Dadurch wird der erste Teil 3a maximal in das Gehäuse 10 hineinbewegt bis er am Teil 3b anliegt. Dies führt zu einer maximalen Komprimierung des Kraftspeichers 2b (so wie in Fig. 4a) und weiters ab der in Fig. 4a dargestellten Position des ersten Teils 3a auch zu einer Komprimierung der Kraftspeicher 2a, welche zwischen dem ersten Teil 3a und dem zweiten Teil 3b angeordnet sind. In Folge wird nicht nur der erste Schalter 6a aktiviert, was aber mit keinerlei Konsequenzen verbunden ist (dieser Schalter 6a ist nämlich als "Öffner" ausgeführt), sondern es wird auch der zweite Schalter 6b (ist als "Schließer" ausgeführt) aktiviert, was allerdings in Fig. 4c nicht erkennbar ist. Aufgrund der Aktivierung des zweiten Schalters 6b kommt es zu einer Auslösung der Antriebsvorrichtung und damit zu einem Ausstoßen des Möbelteils 8. Fig. 4c shows the situation in which the furniture part 8 has been moved by the user from the closed position further into the furniture body. As a result, the first part 3a is maximally moved into the housing 10 until it rests against the part 3b. This leads to a maximum compression of the energy storage 2b (as in Fig. 4a ) and further from the in Fig. 4a shown position of the first part 3a also to a compression of the energy storage 2a, which are arranged between the first part 3a and the second part 3b. As a result, not only the first switch 6a is activated, but this is not connected with any consequences (this switch 6a is in fact designed as an "opener"), but also the second switch 6b (executed as a "make contact") is activated, which however in Fig. 4c is not recognizable. Due to the activation of the second switch 6b, a triggering of the drive device and thus an ejection of the furniture part 8 occurs.

Der Schaltvorgang sei nochmals anhand der Fig. 5a bis 5c erläutert.The switching process is again based on the Fig. 5a to 5c explained.

Fig. 5a zeigt die Neutralstellung des Schaltelements 1, wobei auf die Darstellung des Gehäuses 10 verzichtet wurde. In der Vergrößerung H ist erkennbar, das in dieser Stellung der erste Schalter 6a durch den zweiten Teil 3b betätigt ist, während der zweite Schalter 6b durch den ersten Teil 3a nicht betätigt ist. Fig. 5a shows the neutral position of the switching element 1, wherein the representation of the housing 10 has been omitted. In the enlargement H it can be seen that in this position the first switch 6a is actuated by the second part 3b, while the second switch 6b is not actuated by the first part 3a.

In Fig. 5b wurde das Möbelteil 8 und damit der erste Teil 3a und der zweite Teil 3b herausbewegt. Die Vergrößerung G zeigt, dass dies zu einem Freigeben des ersten Schalters 6a durch den zweiten Teil 3b führt, was das Schaltelement 1 aktiv schaltet.In Fig. 5b was the furniture part 8 and thus the first part 3a and the second part 3b moved out. The enlargement G shows that this leads to a release of the first switch 6a through the second part 3b, which activates the switching element 1 actively.

Fig. 5c zeigt die Situation bei eingedrücktem Möbelteil 8 und maximal in das nicht dargestellte Gehäuse 10 hineinbewegten ersten Teil 3a. Die Vergrößerung I zeigt, dass nunmehr nicht nur der zweite Teil 3b den ersten Schalter 6a schaltet, sondern auch der erste Teil 3a den zweiten Schalter 6b schaltet, welche Situation auch in der Fig. 5d in einem Längsschnitt außerhalb der Mittellinie des Schaltelements 1 dargestellt ist. Dies führt ebenfalls zu einer Aktivschaltung des Schaltelements 1. Fig. 5c shows the situation with pressed-in furniture part 8 and maximum in the housing 10, not shown moving in first part 3a. Magnification I shows that now not only the second part 3b switches the first switch 6a, but also the first part 3a switches the second switch 6b, which situation is also shown in FIG Fig. 5d in a longitudinal section outside the center line of the switching element 1 is shown. This also leads to an active circuit of the switching element. 1

Die Fig. 6a und 6b zeigen zwei Ausführungsbeispiele des Schaltelements 1, wobei im bevorzugten Ausführungsbeispiel 6a zwei Kraftspeicher 2a, 2b mit unterschiedlich steilen Kennlinien K1, K2 zum Einsatz kommen. Zum Kraftspeicher 2a gehört dabei die Kennlinie K1 und zum Kraftspeicher 2b gehört die Kennlinie K2. Erkennbar ist, dass über die Teilstrecke zwischen den Positionen S1 und S2 nur der erste Kraftspeicher 2a das Betätigungselement 3 beaufschlagt. Bei der Position S2 ist der Kraftspeicher 2a maximal gespannt (komprimiert) und der zweite Kraftspeicher 2b kommt zur Anlage. Durch die Knickstelle beim Übergang vom K1 auf K2. ist bei der Position S2 ein definierter Schaltpunkt ausgebildet.The Fig. 6a and 6b show two embodiments of the switching element 1, wherein in the preferred embodiment 6a two energy storage 2a, 2b come with different steep curves K 1 , K 2 are used. The energy storage device 2a includes the characteristic curve K 1 and the energy storage device 2b includes the characteristic curve K 2 . It can be seen that only the first energy store 2 a acts on the actuating element 3 via the partial distance between the positions S 1 and S 2 . At the position S 2 , the energy storage 2a is maximally tensioned (compressed) and the second energy storage 2b comes to rest. Due to the kink at the transition from K 1 to K 2 . is formed at the position S 2 a defined switching point.

Ein zweites Ausführungsbeispiel ist in Fig. 6b dargestellt. Hierbei weist die Kennlinie K2 genau die doppelte Steigung der Kennlinie K1 auf. Dies ist darauf zurückzuführen, dass die Kennlinie K1 nur durch die Einwirkung eines einzigen Kraftspeichers 2a zwischen den Positionen S1 und S2 erzeugt wird. Dieser erste Kraftspeicher 2a ist aber bei der Position S2 noch nicht maximal komprimiert, sondern kann weiterhin Kraft ausüben. Bei Position S2 kommt allerdings ein zweiter, identisch ausgebildeter Kraftspeicher 2b zur Anlage, sodass sich ab Position S2 beide Kraftwirkungen auf das Betätigungselement 3 addieren. Wiederum ist bei der Position S2 ein definierter Schaltpunkt realisiert, wobei allerdings in diesem Ausführungsbeispiel 6b die Definition des Schaltpunkts aufgrund des geringfügigeren Knickes (Winkel zwischen den Kennlinien K1 und K2) weniger gut definiert ist.A second embodiment is in Fig. 6b shown. Here, the characteristic K 2 exactly twice the slope of the characteristic K 1 on. This is due to the fact that the characteristic curve K 1 is generated only by the action of a single energy storage 2a between the positions S 1 and S 2 . This first energy storage 2a is not yet maximally compressed at the position S 2 , but can continue to exert force. At position S 2 , however, a second, identically designed energy storage 2b comes to rest, so that from the position S 2 both force effects add to the actuating element 3. Again, a defined switching point is realized at the position S 2 , although in this embodiment 6 b the definition of the switching point due to of the minor kink (angle between the curves K 1 and K 2 ) is less well defined.

Die Fig. 8 bis 10 zeigen eine weitere Variante eines erfindungsgemäßen Schaltelements 1.The Fig. 8 to 10 show a further variant of a switching element 1 according to the invention.

Bei dieser Variante wird der definierte Schaltpunkt dadurch erreicht, dass gesondert vom Betätigungselement 3 wenigstens ein weiteres, durch zumindest einen Kraftspeicher 2b beaufschlagtes Element 15 vorgesehen ist.In this variant, the defined switching point is achieved in that separately from the actuating element 3 at least one further, acted upon by at least one energy storage element 2b element 15 is provided.

Fig. 8a zeigt ein Ausführungsbeispiel eines derartigen Schaltelements 1. Symmetrisch neben dem Betätigungselement 3 sind dabei zwei in Form von Stiften ausgebildete Elemente 15 vorgesehen. Weiters sind Leuchtelemente 11 zu erkennen. Fig. 8a shows an embodiment of such a switching element 1. Symmetrically next to the actuating element 3 while two formed in the form of pins elements 15 are provided. Furthermore, lighting elements 11 can be seen.

Fig. 8b zeigt eine Explosionsdarstellung, wobei erkennbar ist, dass das Betätigungselement 3 einen Zahnstangenfortsatz aufweist, welcher mit dem Zahnrad 16 eines auf einer Platine 14 angeordneten Potentiometers 17 kämmt. Das Potentiometer 17 dient dabei dazu, eine Bewegung des Betätigungselements 3 zu detektieren und über die elektrischen Leitungen 7 an eine nicht dargestellte Steuer- bzw. Regeleinrichtung zur Auslösung einer Antriebsvorrichtung weiterzuleiten. Natürlich dienen die elektrischen Leitungen 7 auch zur Stromversorgung des Schaltelements 1. Fig. 8b shows an exploded view, wherein it can be seen that the actuating element 3 has a rack extension, which meshes with the gear 16 of a arranged on a board 14 potentiometer 17. The potentiometer 17 serves to detect a movement of the actuating element 3 and forward it via the electrical lines 7 to a control or regulating device, not shown, for triggering a drive device. Of course, the electrical leads 7 also serve to supply power to the switching element 1.

Die beiden Elemente 15 werden durch jeweils einen Kraftspeicher 2a beaufschlagt. Jeder der beiden Kraftspeicher 2a ist dabei kürzer ausgebildet als der Kraftspeicher 2b, was zur Folge hat, dass ohne die Einwirkung einer Gegenkraft das Betätigungselement 3 am weitesten von der Frontplatte 18 des Schaltelements 1 absteht.The two elements 15 are acted upon by a respective energy storage 2a. Each of the two energy storage 2a is designed to be shorter than the energy storage 2b, which has the consequence that, without the action of a counter force, the actuating element 3 protrudes furthest from the front plate 18 of the switching element 1.

Weiters in Fig. 8 erkennbar sind ein Deckel 19, ein Kabelhalter 20' sowie zwei Einbaustifte 21, welche der Fixierung des Schaltelements 1 in einer Bohrung in einem Möbelkorpus dienen. Die elektrischen Leitungen 7 verlaufen geschützt in einem Kanal 20, welcher in einer Bohrung eines Möbelkorpus platziert werden kann.Further in Fig. 8 discernible are a cover 19, a cable holder 20 'and two mounting pins 21, which serve to fix the switching element 1 in a bore in a furniture carcass. The electrical leads 7 are protected in a channel 20, which can be placed in a bore of a furniture body.

Die Funktionsweise des Schaltelements nach der Fig. 8 sei anhand der Fig. 9a bis 9c erläutert.The operation of the switching element after the Fig. 8 be based on the Fig. 9a to 9c explained.

Fig. 9a zeigt die Neutralstellung des Schaltelements 1, in welcher dieses nicht aktiv ist. Fig. 9a shows the neutral position of the switching element 1, in which this is not active.

Ein nicht dargestelltes Möbelteil 8 liegt dabei sowohl am Betätigungselement 3 als auch an den Elementen 15 an. Hierdurch wird das Betätigungselement 3 derart weit eingedrückt, dass es in einer Fläche mit den Elementen 15 liegt.An unrepresented furniture part 8 rests both on the actuating element 3 and on the elements 15. As a result, the actuating element 3 is pressed so far that it lies in a surface with the elements 15.

Fig. 9b zeigt die Situation nach einer Herausbewegung des Möbelteils 8 durch einen Benutzer. Das Betätigungselement 3 kann sich nunmehr unter der Einwirkung des Kraftspeichers 2b von der Frontplatte 18 maximal wegbewegen. Diese Bewegung wird durch das Potentiometer 17 detektiert und führt zur Auslösung der Antriebsvorrichtung. Bei dieser Funktionalität spielen die Elemente 15 keine Rolle. Fig. 9b shows the situation after a movement of the furniture part 8 by a user. The actuating element 3 can now move away from the front plate 18 under the effect of the force accumulator 2b. This movement is detected by the potentiometer 17 and leads to the triggering of the drive device. In this functionality, the elements 15 play no role.

Fig. 9c zeigt die Situation nachdem das Möbelteil 8 maximal in den Möbelkorpus hineingedrückt wurde. Dadurch haben sich sowohl das Betätigungselement 3 als auch die Elemente 15 aus der in Fig. 9a dargestellten Lage in die in Fig. 9c dargestellte Lage bewegt. Dadurch das der Benutzer beim Übergang von der Lage der Fig. 9a in die Lage der Fig. 9c sowohl das Betätigungselement 3 als auch die Elemente 15 gegen die Beaufschlagung der jeweiligen Kraftspeicher 2a, 2b eindrücken musste, hat er den definierten Schaltpunkt bemerkt, welcher der in Fig. 9a dargestellten Positionen des Betätigungselements 3 und der Elemente 15 entspricht. Fig. 9c shows the situation after the furniture part 8 was maximally pressed into the furniture body. As a result, both the actuating element 3 and the elements 15 from the in Fig. 9a shown location in the in Fig. 9c shown position moves. This allows the user to transition from the location of Fig. 9a in the location of Fig. 9c Both the actuator 3 and the elements 15 had to press against the action of the respective energy storage 2a, 2b, he has noticed the defined switching point, which in Fig. 9a shown positions of the actuating element 3 and the elements 15 corresponds.

Fig. 10 zeigt das Schaltelement 1 im eingebauten Zustand in einem Möbelkorpus, jedoch vor dem Eindrücken der Haltestifte 21 zur Fixierung des Schaltelements 1. Fig. 10 shows the switching element 1 in the installed state in a furniture body, but before pressing the retaining pins 21 for fixing the switching element. 1

Das Potentiometer kann zum Beispiel als Linearpotentiometer oder Drehpotentiometer (wie in den Figuren dargestellt) ausgebildet sein.The potentiometer can be designed, for example, as a linear potentiometer or rotary potentiometer (as shown in the figures).
