Abstract

A remote control transmitter contains on a circuit board (3), which is rigidly connected to the transmitter housing (1) of the remote control transmitter, a positional-deviation switch configuration (17), which in the event of an angular deviation of the circuit board (3) and thus of the remote control transmitter beyond a particular trigger angle (ao) from a particular given or instantaneously determined reference operating position generates an output signal designating the direction of the positional deviation. In a signal converter (5) of the remote control transmitter, this direction-dependent output signal is converted as a control command into a transmission signal, and emitted via a transmitter element (4) of the remote control transmitter to a remotely controlled electrical appliance. By means of swivel movements of the remote control transmitter from the wrist of the user operating the remote control transmitter, different control commands to the remotely controlled appliance are generated in this way in the remote control transmitter.

Description

Die Erfindung betrifft einen Fernbedienungsgeber nach dem Oberbegriff des Anspruches 1.The invention relates to a remote control transmitter according to the preamble of claim 1.

Derartige Fernbedienungsgeber dienen zur Steuerung elektrischer Geräte über eine drahtlose Verbindung, insbesondere zur Steuerung photoelektrischer Geräte wie z.B. Dia- oder Filmprojektoren, oder zur Steuerung von Geräten der Unterhaltungselektronik, beispielsweise zur Steuerung von Fernsehgeräten oder Videorecordern. Solche Fernbedienungsgeber sind beispielsweise aus der Zeitschrift Funkschau 1978, Heft 9, S. 405 - 407 oder der Zeitschrift Funkschau 1978, Heft 20, S. 963 - 966 bekannt. Die bekannnten Fernbedienungsgeber enthalten auf der Bedienungsseite eines Gebergehäuses ein Tastenfeld als Eingabevorrichtung. Durch Betätigen einzelner Tasten dieses Tastenfeldes wählt der Benutzer des Fernbedienungsgebers Steuerbefehle zur Einstellung oder Veränderung bestimmter Betriebszustände eines mit dem Fernbedienungsgeber gesteuerten elektrischen Gerätes. In einem Signalwandler des Fernbedienungsgebers werden die mit den betätigten Tasten abgerufenen Steuerbefehle in Übertagungssignale umgewandelt und von einem Infrarotsendeelement an das zu steuernde elektrische Gerät abgestrahlt wird.Such remote control transmitters are used to control electrical devices via a wireless connection, in particular to control photoelectric devices such as slide or film projectors, or to control consumer electronics devices, for example to control television sets or video recorders. Such remote control transmitters are known, for example, from the magazine Funkschau 1978, number 9, pp. 405-407 or the magazine Funkschau 1978, number 20, pp. 963-966. The known remote control encoders contain a keypad on the operating side of an encoder housing as an input device. By pressing individual buttons on this keypad, the user of the remote control transmitter selects control commands for setting or changing certain operating states of an electrical device controlled by the remote control transmitter. In a signal converter of the remote control transmitter, the control commands called up with the actuated keys are converted into transmission signals converted and emitted by an infrared transmitter element to the electrical device to be controlled.

Der ungeübte Benutzer eines derartigen Fernbedienungsgebers muß sich bei dessen Benutzung oft durch Lesen der Beschriftung des Tastenfeldes wieder kundig machen, welche Tasten er für einen gewünschten Befehl zu betätigen hat. Dies ist für ihn selbst schon bei einem Tastenfeld mit verhältnismäßig wenig Tasten umständlich und zeitraubend. Oft ist er darüber hinaus noch unsicher, ob er tatsächlich die dem gewünschten Steuerbefehl zugeordnete Taste betätigt hat.The inexperienced user of such a remote control transmitter often has to find out which keys he has to press for a desired command by reading the label on the keypad. This is cumbersome and time-consuming for him even with a keypad with relatively few keys. In addition, he is often still unsure whether he has actually pressed the button assigned to the desired control command.

Oft werden zwei oder mehr fernbedienbare elektrische Geräte von einem Benutzer gleichzeitig fernbedient. Dazu sind im allgemeinen zwei Fernbedienungsgeber erforderlich, zwischen denen der Benutzer wechseln muß. Dazu ist in der britischen Druckschrift GB 2146813 A vorgeschlagen, das Gehäuse eines einzigen Fernbedienungsgebers auf seiner Oberseite mit einer Bedienungsfläche für das eine fernzubedienende Gerät zu versehen und auf seiner Unterseite eine zweite Bedienungsfläche für das andere fernzubedienende Gerät anzuordnen. Ferner enthält der bekannte Fernbedienungsgeber einen Quecksilberschalter als lageabhängigen Schalter, der stets die nach oben weisende Bedienungsfläche wirksam schaltet.Often, two or more remotely controllable electrical devices are operated remotely by one user. This generally requires two remote control transmitters between which the user has to switch. For this purpose, it is proposed in the British publication GB 2146813 A to provide the housing of a single remote control transmitter on its upper side with a control surface for the one device to be remotely operated and to arrange a second control surface for the other remote control device on its underside. Furthermore, the known remote control transmitter contains a mercury switch as a position-dependent switch which always switches the operating surface facing upward effectively.

Zur Steuerung zweier voneinander unabhängiger Tore, beispielsweise eines Grundstücktores und eines Garagentores oder zweier Garagentore ist in der DE-Druckschrift DE-A-2805896 ein Handsender bekannt, der in einem Gebergehäuse einen Quecksilberschalter und einen in der Frequenz umschaltbaren Oszillator zur Steuerung der Antriebe für die beiden Tore enthält.For the control of two independent gates, for example a property gate and a garage door or two garage doors, a hand transmitter is known in DE-A-2805896, which has a mercury switch and a frequency-switchable oscillator for controlling the drives for the in a transmitter housing contains both gates.

Der Quecksilberschalter kennzeichnet durch seinen Schaltzustand eine aufrecht stehende oder eine liegende Lage des Handsenders und sendet bei der Betätigung eines Drucktasters im Gebergehäuse je nach Schaltzustand des Quecksilberschalters, der die Frequenz des Oszillators umschaltet, ein Steuersignal an den Antrieb des einen oder des anderen Tores, je nach der Lage des Handsenders. Die den Handsender offenbarende Druckschrift liefert lediglich den Hinweis, unterschiedliche elektrische Einrichtungen oder Geräte von der Lage eines Handsenders abhängig ferngesteuert ein- und auszuschalten.The switching state of the mercury switch indicates an upright or lying position of the handheld transmitter and, when a pushbutton is pressed in the transmitter housing, sends a control signal to the drive of one or the other gate, depending on the switching state of the mercury switch that switches the frequency of the oscillator according to the location of the handheld transmitter. The publication disclosing the handheld transmitter merely provides the information that different electrical devices or devices are switched on and off remotely depending on the position of a handheld transmitter.

Der Erfindung liegt die Aufgabe zugrunde, einen Fernbedienungsgeber nach dem Oberbegriff des Anspruches 1 so auszugestalten, daß die Handhabung des Fernbedienungsgebers auch für den ungeübten Benutzer wenigstens für die Einstellung wesentlicher Betriebszustände oder Betriebsabläufe des mit dem Fernbedienungsgeber fernzubedienenden Gerätes wesentlich vereinfacht ist. Diese Aufgabe wird nach der Erfindung durch die Merkmale des Anspruches 1 gelöst.The invention has for its object to design a remote control transmitter according to the preamble of claim 1 so that the handling of the remote control transmitter for the inexperienced user at least for the setting of essential operating conditions or operations of the device to be operated with the remote control transmitter is significantly simplified. This object is achieved according to the invention by the features of claim 1.

Der Erfindung liegt die Erfahrung zugrunde, daß einzelne Abläufe des täglichen Lebens durch bestimmte Handbewegungen gekennzeichnet werden können. So wird eine Vergrößerung eines Ereignisses oder ein vorwärts gerichteter schrittweiser Fortgang oder ein vorwärtsgehendes Weiterblättern durch eine Handbewegung nach rechts oder nach oben gekennzeichnet. Wird beispielsweise ein Weiterblättern in den Funktionsebenen eines fernzusteuernden Gerätes in eine Aufwärts- oder Abwärtsbewegung des in der Hand des Benutzers geführten Fernbedienungsgebers gelegt und diese Funktionsebene im fernbedienten Gerät angezeigt, kann der Benutzer eines erfindungsgemäßen Fernbedienungsgebers ohne Beobachten des Fernbedienungsgebers selbst nur durch aufwärts oder abwärts gerichtete Handbewegungen in den Funktionsebenen des fernbedienten Gerätes blättern. In gleicher Weise kann er durch eine Rechts- oder Linksbewegung der Hand, bei der unwillkürlich auch eine Drehbewegung in der Achse der Hand erfolgt, einen Vorwärts- oder einen Rückwärtslauf einschalten oder Ereignisse verstärken oder dämpfen, ohne daß er seine Aufmerksamkeit auf den benutzten Fernbedienungsgeber richten muß. Außerdem erfordert die Bedienung eines erfindungsgemäßen Fernbedienungsgebers lediglich eine Hand, so daß der Benutzer eines derartigen Fernbedienungsgebers während dessen Benutzung die zweite Hand frei hat für andere Tätigkeiten.The invention is based on the experience that individual processes of daily life can be characterized by certain hand movements. An enlargement of an event or a forward step-by-step progression or a forward scrolling is characterized by a hand movement to the right or upwards. If, for example, a scrolling in the functional levels of a device to be controlled remotely is placed in an upward or downward movement of the remote control transmitter carried in the hand of the user, and this functional level in remotely operated device displayed, the user of a remote control transmitter according to the invention can even scroll through the upward or downward hand movements in the functional levels of the remote controlled device without observing the remote control transmitter. In the same way, by moving the hand to the right or left, which involuntarily involves a rotation in the axis of the hand, he can switch on a forward or a reverse run or amplify or dampen events without paying attention to the remote control transmitter used got to. In addition, the operation of a remote control transmitter according to the invention requires only one hand, so that the user of such a remote control transmitter has the second hand free for other activities during its use.

Der die Betriebslage des in der britischen Druckschrift GB-A-2146813 offenbarten Fernbedienungsgebersgebers anzeigende Quecksilberschalter dient nur zum selbsttätigen Einschalten der zugehörigen Bedienungsfläche dieses Fernbedienungsgebers anstelle eines von Hand an einem Bedienungselement betätigbaren Umschalters. Er dient nicht zur Erzeugung von Steuerbefehlen für die fernzubedienenden Geräte.The mercury switch indicating the operating position of the remote control transmitter disclosed in the British publication GB-A-2146813 is used only for automatically switching on the associated operating surface of this remote control instead of a switch which can be actuated manually on an operating element. It is not used to generate control commands for the devices to be operated remotely.

Das gleiche gilt für den aus der FR-Druckschrift FR-A-1401384 bekannten HF-Empfänger. In diesem elektrischen Gerät wird der Frequenzempfangsbereich mittels lageabhängiger Quecksilberschalter eingestellt, deren Schalterstellung nicht von der Stellung eines oder mehrerer Bedienungselemente eines Schalters, sondern allein von der Art der Aufstellung des Empfängers bestimmt ist.The same applies to the HF receiver known from FR document FR-A-1401384. In this electrical device, the frequency reception range is set by means of position-dependent mercury switches, the switch position of which is not determined by the position of one or more operating elements of a switch, but solely by the type of installation of the receiver.

Andererseits führt auch die Kenntnis der FR-Druckschrift FR-A-2510900 nicht dazu, die oben genannte Aufgabe zu lösen. Aus dieser Druckschrift ist ein mit einer Hand bedienbarer Joystick (Steuerknüppel) zur Fernsteuerung der Verlagerung von Objekten auf einem Bildschirm oder zur Fernsteuerung anderer beweglicher Objekte bekannt. Für diesen Joystick wird ein in der Hand haltbares Gehäuse mit Schwerkraftschaltern unterschiedlichster Ausgestaltung als Koordinatenschalter vorgeschlagen. Derartige Joysticks dienen somit lediglich zur Steuerung einer Bewegung in der Fläche oder im Raum.On the other hand, knowledge of FR document FR-A-2510900 does not lead to the above-mentioned problem being solved. From this publication, a joystick (joystick) that can be operated with one hand for remote control of the displacement of objects on a screen or for remote control of other moving objects is known. For this joystick, a hand-held housing with gravity switches of various designs is proposed as a coordinate switch. Such joysticks are therefore only used to control movement in the surface or in space.

Die Unteransprüche kennzeichnen vorteilhafte Ausgestaltungen der Erfindung. Besonders vorteilhaft ist es, für die Ermittlung von Lagedifferenzen des Gebergehäuses des Fernbedienungsgebers, Schwerkraftschalter zu verwenden, da die Erdgravitation ein für jedes menschliche Tun definiert gerichtetes Kraftfeld zum Erdmittelpunkt hin darstellt. Es ist jedoch auch möglich, eine Schwenkbewegung eines in der Hand eines Benutzers gehaltenen Fernbedienungsgebers durch Beschleunigungsschalter zu erfassen, mit denen die Lagedifferenzschalteranordnung des Fernbedienungsgebers ausgerüstet ist, und daraus Steuerbefehle zur Fernsteuerung eines elektrischen Gerätes abzuleiten. In einer weiteren Ausgestaltung der Erfindung enthält die Lagedifferenzschalteranordnung des Fernbedienungsgebers Sensoren, die richtungsabhängig die Intensität eines bestimmten Strahlungs- oder Kraftfeldes erfassen und durch ein elektrisches Signal darstellen. Bleiben diese Signale über einen bestimmten Zeitabschnitt hinaus konstant, kennzeichnen sie nach einer Ausgestaltung der Erfindung eine Ruhelage des Fernbedienungsgebers,die für ihn als Referenzbedienungslage gilt.Zu einem bestimmten Zeitpunkt ermittelte Werte dieser Signale bilden nach einer weiteren Ausgestaltung der Erfindung ebenfalls die Referenzwerte für eine Ruhelage des Fernbedienungsgebers. Bei einer Änderung der Lage des Fernbedienungsgebers aus dieser Ruhelage heraus durch eine Schwenkbewegung des in der Hand gehaltenen Fernbedienungsgebers wird aus den neuen Ausgangssignalen der Sensoren die Richtung der Schwenkbedienung ermittelt und daraus die zugehörigen Steuerbefehle dekodiert. Ein derartiges Strahlungs- oder Kraftfeld ist beispielsweise das erdmagnetische Feld oder das Strahlungsfeld einer bestimmten Strahlungsquelle, beispielsweise einer Quelle einer elektromagnetischen Strahlung.The subclaims characterize advantageous embodiments of the invention. It is particularly advantageous to use gravity switches to determine the position differences of the transmitter housing of the remote control transmitter, since gravity represents a force field that is defined for every human activity and directed towards the center of the earth. However, it is also possible to detect a pivoting movement of a remote control transmitter held in the hand of a user by means of acceleration switches with which the position difference switch arrangement of the remote control transmitter is equipped, and to derive control commands for remote control of an electrical device. In a further embodiment of the invention, the position difference switch arrangement of the remote control transmitter contains sensors which depend on the direction of the intensity of a particular radiation or Detect the force field and display it with an electrical signal. If these signals remain constant over a certain period of time, according to one embodiment of the invention, they indicate a rest position of the remote control transmitter, which for him is the reference operating position. According to a further embodiment of the invention, values of these signals also form the reference values for a rest position of the remote control transmitter. If the position of the remote control transmitter changes from this rest position by a swiveling movement of the remote control transmitter held in the hand, the direction of the swivel operation is determined from the new output signals from the sensors and the associated control commands are decoded therefrom. Such a radiation or force field is, for example, the earth's magnetic field or the radiation field of a specific radiation source, for example a source of electromagnetic radiation.

Die Figuren 1a und 1b zeigen in einer schematischen Darstellung die Seitenansicht eines Fernbedienungsgebers, der im Falle der Figur 1a um einen Neigungswinkel α aus seiner waagerechten Lage nach oben verschwenkt ist und im Falle der Figur 1b aus der waagerechten Lage um den Neigungswinkel α nach unten verschwenkt ist. Das Gebergehäuse 1 ist längs einer senkrechten Ebene durch die Hauptachse 2 des Fernbedienungsgebers aufgeschnitten gezeichnet, sodaß die wesentlichen Bauelemente des Fernbedienungsgebers schematisch dargestellt werden können. Auf einer unbeweglich mit dem Gebergehäuse verbundenen Platte 3 sind das Gebergehäuse durchsetzende Sendeelemente 4, eine Signalwandlerschaltung 5, eine Drucktaste 6, mehrere Schwerkraftschalter 7, 8, 9 und eine diesen zugehörige Schaltungsanordnung 10 angeordnet. Zur Stromversorgung enthält der Fernbedienungsgeber eine Batterie 11.Figures 1a and 1b show a schematic representation of the side view of a remote control transmitter, which in the case of Figure 1a is pivoted upwards from its horizontal position by an angle of inclination α and in the case of Figure 1b is pivoted downwards by the angle of inclination α from the horizontal position is. The encoder housing 1 is drawn cut open along a vertical plane through the main axis 2 of the remote control transmitter, so that the essential components of the remote control transmitter can be shown schematically. On a plate 3 immovably connected to the transmitter housing there are transmitting elements 4, one passing through the transmitter housing Signal converter circuit 5, a push button 6, a plurality of gravity switches 7, 8, 9 and a circuit arrangement 10 associated therewith are arranged. The remote control transmitter contains a battery 11 for the power supply.

Die Schwerkraftschalter 7, 8 und 9 weisen eine Ruhelage auf, die dann besteht, wenn deren Hauptachse 12 parallel zur Gravitationsrichtung 13 liegt. Wird einer der Schwerkraftschalter z.B. der Schwerkraftschalter 7 aus seiner Ruhelage 14 in einer bestimmten Richtung 15 in eine zur Ruhelage 14 um einen Winkel α geneigte Lage 16 verschwenkt, deren Neigungswinkel α größer als ein Auslösewinkel α₀ ist, wie in Figur 2 schematisch dargestellt ist, dann erzeugt dieser Schwerkraftschalter ein Ausgangssignal. Werden mehrere derartige Schwerkraftschalter 7, 8, 9 so auf der Platte 3 des Fernbedienungsgebers angeordnet, daß ihre Wirkrichtungen 15 in unterschiedliche Richtungen zeigen, kann eine mit derartigen Schaltern ausgebildete Lagedifferenzschalteranordnung 17 ein Verschwenken des Fernbedienungsgebers aus seiner waagerechten Lage, die die Referenzbedienungslage des Fernbedienungsgebers bezüglich aller Schwenkbewegungen zur Steuerung eines fernbedienbaren elektrischen Gerätes darstellt, durch seine Ausgangssignale kenntlich machen. Aus den von den Schwerkraftschaltern des Fernbedienungsgebers erzeugten Ausgangssignalen bildet der ebenfalls zu der Lagedifferenzschalteranordnung 17 gehörende Richtungssignalwandler 10 ein die Richtung der Lageabweichung von der waagerechten Referenzbedienungslage des Fernbedienungsgebers kennzeichnendes Signal, das als Steuerbefehl von der Signalwandlerschaltung 5 in ein Übertragungssignal für die Sendeelemente 4 umgesetzt wird.The gravity switches 7, 8 and 9 have a rest position, which exists when their main axis 12 is parallel to the direction of gravity 13. If one of the gravity switches, for example the gravity switch 7, is pivoted from its rest position 14 in a certain direction 15 into a position 16 inclined to the rest position 14 by an angle α, the inclination angle α of which is greater than a triggering angle α₀, as is shown schematically in FIG. 2, then this gravity switch generates an output signal. If several such gravity switches 7, 8, 9 are arranged on the plate 3 of the remote control transmitter so that their directions of action 15 point in different directions, a position difference switch arrangement 17 designed with such switches can pivot the remote control transmitter out of its horizontal position, which relates to the reference operating position of the remote control transmitter represents all swiveling movements for controlling a remote-controlled electrical device, by its output signals. From the output signals generated by the gravity switches of the remote control transmitter, the directional signal converter 10, which also belongs to the position difference switch arrangement 17, forms a signal characterizing the direction of the position deviation from the horizontal reference operating position of the remote control transmitter, which signal is converted as a control command by the signal converter circuit 5 into a transmission signal for the transmission elements 4.

Zur Fernsteuerung eines elektrischen Gerätes hält der Benutzer des Fernbedienungsgebers diesen Fernbedienungsgeber so in einer Hand, daß er mit dem Daumen 18 dieser Hand die aus dem Gebergehäuse 1 herausragende Drucktaste 6 eines Einschalters 19 des Fernbedienungsgebers betätigen kann. Mit der Betätigung dieser Drucktaste 6 ist die Lagedifferenzschalteranordnung 17 des Fernbedienungsgebers eingeschaltet, sodaß sie eine Verschwenkungslage des in der Hand gehaltenen Fernbedienungsgebers infolge einer Schwenkbewegung der Hand des Benutzers erkennen und daraus einen Steuerbefehl bilden kann. Beim Verschwenken des in waagerechter Lage gehaltenen Fernbedienungsgebers nach rechts oder nach links wird der Fernbedienungsgeber durch eine unwillkürliche zusätzliche Verdrehung der Hand beim Verschwenken der Hand um seine Hauptachse 2 gedreht, sodaß eine Neigung des Gebergehäuses 1 zur Waagerechten nach der Seite auftritt, wie dies beispielsweise in Figur 1c dargestellt ist. In dieser Figur ist gestrichelt die von dem Gebergehäuse 1 des Fernbedienungsgebers umgebene Platte 3 und der auf dieser Platte angeordnete Schwerkraftschalter 8 dargestellt, der bei der in der Figur 1c dargestellten seitlichen Neigung des Gebergehäuses von der Waagerechten wirksam ist und bei einem Neigungswinkel α, der größer als der Auslösewinkel α₀ ist, ein Ausgangssignal erzeugt.For remote control of an electrical device, the user of the remote control transmitter holds this remote control transmitter in one hand in such a way that he can actuate the push button 6 of a switch 19 of the remote control transmitter which protrudes from the transmitter housing 1 with this thumb. With the actuation of this pushbutton 6, the position difference switch arrangement 17 of the remote control transmitter is switched on, so that it can recognize a pivoting position of the handheld remote control transmitter as a result of a pivoting movement of the hand of the user and can form a control command therefrom. When the remote control transmitter held in a horizontal position is pivoted to the right or to the left, the remote control transmitter is rotated by an involuntary additional rotation of the hand when the hand is pivoted about its main axis 2, so that an inclination of the transmitter housing 1 to the horizontal to the side occurs, as is the case, for example, in Figure 1c is shown. In this figure, the plate 3 surrounded by the transmitter housing 1 of the remote control transmitter and the gravity switch 8 arranged on this plate are shown in broken lines, which is effective from the horizontal in the case of the lateral inclination of the transmitter housing shown in FIG. 1c and at an angle of inclination α which is greater than the trigger angle is α₀, generates an output signal.

Tritt bei einer Betätigung der Drucktaste 6 keiner der Schwerkraftschalter 7, 8, 9 des Fernbedienungsgebers ein Ausgangssignal auf, ermittelt daraus der Richtungssignalwandler 10, daß sich der Fernbedienungsgeber in der Referenzbedienungslage, d.h. in waagerechter Lage befindet und erzeugt ein der Ruhelage des Fernbedienungsgebers zugeordnetes Ausgangssignal, das ebenfalls als Steuerbefehl verwendet und dem Singnalwandler 5 zu Übertragung an deas fernzusteuernde Gerät zugeführt wird. Zur Darstellung der vier Neigungsrichtungen: Gebergehäuse nach oben oder nach unten geneigt oder Gebergehäuse nach rechts oder nach links um seine Hauptachse gedreht, enthält im dargestellten Ausführungsbeispiel die Lagedifferenzschalteranordnung 17 des in den Figuren 1a bis 1c dargestellten Fernbedienungsgebers vier Schwerkraftschalter, von denen die drei Schwerkraftschalter 7, 8 und 9 schematisch dargestellt sind.
In einem anderen Ausführungsbeispiel enthält die Lagedifferenzschalteranordnung 17 einen fünften Schwerkraftschalter, der bei einer Lage, deren Winkelabweichung der Hauptachse des Schwerkraftschalters von der Gravitationsrichtung 13 geringer ist als der Auslösewinkel α₀ der übrigen vier Schwerkraftschalter, richtungsunabhängig ein Ausgangssignal erzeugt und damit eine Lage um die Ruhelage des Fernbedienungsgebers kennzeichnet.If none of the gravity switches 7, 8, 9 of the remote control transmitter gives an output signal when the pushbutton 6 is actuated, the directional signal converter 10 determines from this that the remote control transmitter is in the reference control position, ie in a horizontal position, and generates an output signal assigned to the rest position of the remote control transmitter. the also used as a control command and is fed to the signal converter 5 for transmission to the device to be remotely controlled. To illustrate the four directions of inclination: encoder housing inclined upwards or downwards or encoder housing rotated to the right or to the left about its main axis, the position difference switch arrangement 17 of the remote control transmitter shown in FIGS. 1a to 1c contains four gravity switches, of which the three gravity switches 7 , 8 and 9 are shown schematically.
In another exemplary embodiment, the position difference switch arrangement 17 contains a fifth gravity switch which, in the case of a position whose angular deviation of the main axis of the gravity switch from the gravitational direction 13 is less than the trigger angle α₀ of the other four gravity switches, generates an output signal regardless of direction and thus a position around the rest position of the Remote control transmitter.

In einem weiteren Ausführungsbeispiel sind die die Neigung des Fernbedienungsgebers gegenüber einer Referenzbedienungslage des Fernbedienungsgebers feststellenden Elemente keine Schwerkraftschalter, sondern den von der Gravitationsrichtung abweichenden Winkel feststellende, richtungsabhängige Sensoren, die ein vom Betrag der Winkelablage abhängiges elektrisches Ausgangssignal erzeugen. In diesem Fall erzeugt der Richtungssignalwandler 10 oberhalb einer bestimmten Winkelablage ein richtungsabhängiges Ausgangssignal, sodaß die Neigungssensoren in Verbindung mit der Schalteigenschaft des Richtungssignalwandlers 10 wiederum Schwerkraftschalter darstellen. In diesem Fall kann an der Lagedifferenzschalteranordnung 17 die für die Fernbedienung durch eine Schwenkbewegung des Fernbedienungsgebers günstigte Schalthysterese eingestellt werden.In a further exemplary embodiment, the elements which determine the inclination of the remote control transmitter relative to a reference operating position of the remote control transmitter are not gravity switches, but rather the direction-dependent sensors which determine the angle deviating from the gravitational direction and which generate an electrical output signal which is dependent on the amount of the angular offset. In this case, the directional signal converter 10 generates a direction-dependent output signal above a certain angular offset, so that the inclination sensors in conjunction with the switching property of the directional signal converter 10 in turn represent gravity switches. In this case, the Position difference switch arrangement 17 which are set for the remote control by a pivoting movement of the remote control transmitter hysteresis.

In den folgenden Figuren 3 bis 6 werden einige Ausführungsbeispiele einer Lagedifferenzschalteranordnung 17 von Fernbedienungsgebern mit Schwerkraftschaltern näher erläutert. Zu dem in den Figuren 3, 4a und 4b dargestellten Ausführungsbeispiel ist in Figur 3 ein Ausschnitt einer Schaltungsplatte 3 an der Stelle der Lagedifferenzschalteranordnung 17 eines Fernbedienungsgebers dargestellt. Die Schaltungsplatte 3 enthält an dieser Stelle eine achsensymmetrische Ausnehmung 20, deren Ränder 21 leicht in die Ausnehmung 20 hinein gewölbt sind. An jedem Rand sind in der Mitte ein schmaleres Kontaktelement 22 und links und rechts davon ein breiteres Kontaktelement 23 angebracht. In der waagerechten Platte ist eine in der Zeichnung gestrichelt dargestellte Kugel 24 gelagert. Die hochleitend ausgebildete Oberfläche 25 (Figur 4a und 4b) lagert in dieser Stellung auf den mittleren Kontaktelementen 22 der Ränder 21 in der Ausnehmung 20 und verbindet dadurch die mittleren Kontaktelemente 22 elektrisch miteinander. Die Kugel 24 bildet so mit den mittleren Kontaktelementen 22 einen Schwerkraftschalter zur Kennzeichnung einer etwa waagerechten Ruhelage des Fernbedienungsgebers. Die vier Ecken der viereckigen Ausnehmung 20 in der Schaltungsplatte 3 weisen in die vier Richtungen, in denen die übrigen vier Schwerkraftschalter wirksam werden. Die Kontaktelemente 23 an den Ecken je zweier zusammenstoßender Ränder 21 der Ausnehmung bilden zusammen mit der Kugel 20 je einen weiteren Schwerkraftschalter, dessen Kontaktelemente in der Ruhelage des Fernbedienungsgebers durch die Kugel nicht elektrisch verbunden sind. Erst bei einer Neigung des Fernbedienungsgebers in einer der Richtungen, in die die Ecken der Ausnehmung 20 weisen und bei der der Schwerpunkt der Kugel 24 die senkrechte Ebene durch die Auflagepunkte der Kugel am Rand 21 der Ausnehmung 20 durchdringt, rollt die Kugel entlang der beiden Ränder 21, die die Spitze in Richtung der Neigung des Fernbedienungsgebers bilden bis in eine durch einen Anschlag begrenzte Position, in der die Kugel die beiden der Spitze zunächst liegenden Kontaktelemente 23 verbindet. Eine derartige Lage ist in Figur 4b für einen Schwenk des Fernbedienungsgebers nach oben dargestellt.In the following FIGS. 3 to 6, some exemplary embodiments of a position difference switch arrangement 17 from remote control transmitters with gravity switches are explained in more detail. For the exemplary embodiment shown in FIGS. 3, 4a and 4b, a section of a circuit board 3 is shown in FIG. 3 at the location of the position difference switch arrangement 17 of a remote control transmitter. At this point, the circuit board 3 contains an axially symmetrical recess 20, the edges 21 of which are slightly curved into the recess 20. A narrower contact element 22 is attached to each edge in the middle, and a wider contact element 23 is attached to the left and right thereof. A ball 24 shown in broken lines in the drawing is mounted in the horizontal plate. In this position, the highly conductive surface 25 (FIGS. 4a and 4b) rests on the middle contact elements 22 of the edges 21 in the recess 20 and thereby electrically connects the middle contact elements 22 to one another. The ball 24 thus forms with the central contact elements 22 a gravity switch for identifying an approximately horizontal rest position of the remote control transmitter. The four corners of the square recess 20 in the circuit board 3 point in the four directions in which the remaining four gravity switches are effective. The contact elements 23 at the corners of two colliding edges 21 of the recess together with the ball 20 each form a further gravity switch, the contact elements of which are not caused by the ball in the rest position of the remote control transmitter are electrically connected. Only when the remote control transmitter is inclined in one of the directions in which the corners of the recess 20 point and in which the center of gravity of the ball 24 penetrates the vertical plane through the support points of the ball on the edge 21 of the recess 20 does the ball roll along the two edges 21, which form the tip in the direction of the inclination of the remote control transmitter, into a position limited by a stop, in which the ball connects the two contact elements 23 initially located at the tip. Such a position is shown in Figure 4b for a pivoting of the remote control transmitter upwards.

Zum Schutz der Kugel 24 und zur Begrenzung von deren Lauf auf den Rändern 21 der Ausnehmung 20 ist in Ausnehmungen 26 der Platte 3 eine Abdeckkappe 27 befestigt, die in der Figur 3 gestrichelt angedeutet und in den Figuren 4a und 4b von der Seite gesehen aufgeschnitten dargestellt ist. Die Kappe 27 enthält einen Anschlagrand 28, der den Lauf der Kugel 20 begrenzt und gegebenenfalls führt. Die gewölbte Ausbildung der Ränder 21 der Ausnehmung 20 trägt ebenfalls zu einer besseren Führung der Kugel 24 in die einzelnen Wirkrichtungen bei. Die einen Kontakte der fünf Schwerkraftschalter sind in dem dargestellten Ausführungsbeispiel gemeinsam mit dem Einschalter 19 des Fernbedienungsgebers über elektrische Leitungen 29 verbunden; die anderen Kontaktelemente dieser Schwerkraftschalter sind einzeln mit einem Richtungssignalwandler 10 verbunden.To protect the ball 24 and to limit its movement on the edges 21 of the recess 20, a cover cap 27 is fastened in recesses 26 of the plate 3, which is indicated by dashed lines in FIG. 3 and shown cut open in FIGS. 4a and 4b is. The cap 27 contains a stop edge 28 which delimits and optionally guides the ball 20. The curved design of the edges 21 of the recess 20 also contributes to better guidance of the ball 24 in the individual directions of action. The one contacts of the five gravity switches are connected in the illustrated embodiment together with the switch 19 of the remote control transmitter via electrical lines 29; the other contact elements of these gravity switches are individually connected to a direction signal converter 10.

In der Figur 4a ist in einer seitlichen Sicht nochmals die Stellung der Kugel 24, die gemeinsames Schaltelement der aus den fünf Schwerkraftschaltern gebildeten Lagedifferenzschalteranordnung 17 ist, in der waagerechten Ruhelage des Fernbedienungsgebers dargestellt, in der die Hauptachse 12 der dargestellten Schalteranordnung parallel zur Gravitationsrichtung 13 verläuft. In Figur 4b ist die in Figur 4a dargestellte Schalteranordnung in einer um den Winkel α nach oben geneigten Stellung des Fernbedienungsgebers dargestellt, in der die Kugel 24 am Anschlagrand 28 der Abdeckkappe 27 anliegt. Der Neigungswinkel α größer ist als der Auslösewinkel αo in dem der Schwerpunkt der Kugel 24 gerade die senkrechte Ebene durch die Auflagepunkte der Kugel auf den Ränder 21 der Ausnehmung 20 in der Platte 3 durchdringt .In FIG. 4a, the position of the ball 24, the common switching element, is again in a side view The five gravity switches position difference switch arrangement 17 is shown in the horizontal rest position of the remote control transmitter, in which the main axis 12 of the switch arrangement shown runs parallel to the direction of gravity 13. FIG. 4b shows the switch arrangement shown in FIG. 4a in a position of the remote control transmitter that is inclined upward by the angle α, in which the ball 24 abuts the stop edge 28 of the cover cap 27. The angle of inclination α is greater than the trigger angle α o in which the center of gravity of the ball 24 just penetrates the vertical plane through the points of contact of the ball on the edges 21 of the recess 20 in the plate 3.

Der in Figur 5 dargestellte Ausschnitt einer Schaltungsplatte 3 eines Fernbedienungsgebers enthält eine Lagedifferenzschalteranordnung 17, bei der ebenfalls eine Kugel 24 in einer Aussparung 30 der Schaltungsplatte gelagert ist. In der Zeichnung ist die kreisrunde Aussparung 30 durch die Kugel 24 verdeckt und gestrichelt dargestellt. Um die Kugel 24 sind auf der Schaltungsplatte 3 kranzförmig vier Schwingspulen 31 angeordnet, d.h. in der Sicht auf das geöffnete Gebergehäuse je eine Schwingspule vor und hinter sowie rechts und links neben der Aussparung 30 in der Schaltungsplatte 3 des Fernbedienungsgebers. Jede dieser Schwingspulen 31 ist mit einem ihr zugehörigen elektrischen Oszillator 32 verbunden. Die Oszillatoren 32 sind so eingestellt, daß sie in der Ruhelage der Kugel 24, in der sie in der Aussparung 30 gelagert ist, eine elektrische Schwingung erzeugen. Sobald sich jedoch die Kugel einer der Schwingspulen nähert und an ihr infolge einer Neigung des Gebergehäuses anliegt, reißt die Schwingung ab. Auf der Schaltungsplatte angeordnete Führungungsstäbe 33 sorgen dafür, daß sich die Kugel 24 bei einer Schwenkbewegung des Fernbedienungsgebers nur einer Schwingspule nähert, sodaß die Schwingung nur eines Oszillators unterbrochen wird. Die Oszillatoren 32 sind an einen Richtungssignalwandler 10 angeschlossen, der ein von der Neigungslage des Fernbedienungsgebers abhängiges Ausgangssignal erzeugt zur Übertragung an ein fernzubedienendes elektrisches Gerät. Die Kugel 24 und die Schwingspulen 31 sind durch eine in der Zeichnung nicht dargestellte Abdeckkappe geschützt und gesichert.The section of a circuit board 3 of a remote control transmitter shown in FIG. 5 contains a position difference switch arrangement 17, in which a ball 24 is likewise mounted in a recess 30 in the circuit board. In the drawing, the circular recess 30 is covered by the ball 24 and shown in dashed lines. Around the ball 24, four voice coils 31 are arranged in a ring shape on the circuit board 3, ie one voice coil each in front of and behind and to the right and left of the recess 30 in the circuit board 3 of the remote control transmitter in the view of the open encoder housing. Each of these voice coils 31 is connected to an associated electrical oscillator 32. The oscillators 32 are set so that they generate an electrical oscillation in the rest position of the ball 24, in which it is supported in the recess 30. However, as soon as the ball approaches one of the voice coils and on it due to an inclination of the If the encoder housing is in contact, the vibration breaks off. Guide rods 33 arranged on the circuit board ensure that the ball 24 approaches only one voice coil when the remote control transmitter is pivoted, so that the oscillation of only one oscillator is interrupted. The oscillators 32 are connected to a directional signal converter 10 which generates an output signal which is dependent on the inclination of the remote control transmitter for transmission to an electrical device to be operated remotely. The ball 24 and the voice coils 31 are protected and secured by a cover cap, not shown in the drawing.

In Figur 6 ist schematisch eine Lagedifferenzschalteranordnung eines Fernbedienungsgebers dargestellt, die einen Flüssigkeitsschalter 34 als Schwerkraftschalter enthält. Dieser Flüssigkeitsschalter ist auf der lagestabil im nicht näher dargestellten Gebergehäuse eines Fernbedienungsgebers befestigten Schaltungsplatte 3 angeordnet und enthält am Boden des Schaltergehäuses 35 einen großflächigen, plattenförmigen Mittenkontakt 36. An der dem Boden gegenüber liegenden Deckwand des Schaltergehäuses 35 sind kranzförmig um den Rand verteilt beispielsweise vier Kontaktelemente 37 wesentlich kleinerer Fläche angeordnet. Das Schaltergehäuse enthält eine nicht netzende, elektrisch leitende Flüssigkeit 41, in der Menge, daß sie bei einer Senkrechtstellung der Leiterplatte 3 nur eines der Kontaktelemente 37 bedeckt. Ab einer bestimmten Neigung der Schaltungsplatte 3 aus der Waagerechten, die einem Auslösewinkel α₀ entspricht, benetzt die leitende Flüssigkeit das Kontaktelement 37, das der Richtung der Neigung der Schaltungsplatte 3 und damit der Richtung der Neigung der Fernbedienungsgebers zugeordnet ist und stellt somit eine leitende Verbindung zwischen dem Mittenkontakt 36 und diesem Kontaktelement 37 her, sodaß der so gebildete Schwerkraftschalter elektrisch leitend geschlossen ist. Die vier Kontaktelemente 37 des Flüssigkeitsschalters 34, von denen in der Zeichnung nur drei dargestellt sind, sind mit einem Richtungssignalwandler 10 verbunden, der aus den über die Kontakte des Flüssigkeitsschalters übertragenen Signalen ein richtungsabhängiges Ausgangssignal bildet, das vom Fernbedienungsgeber in einem Übertragungssignal als Steuerbefehl an ein fernzubedienendes elektrisches Gerät übertragen wird. Als leitende, nicht benetzende Flüssigkeit 41 in dem Schaltergehäuse 35 eignet sich besonders Quecksilber, das wegen seiner Trägheit und Schwere eine hohe Fließdämpfung aufweist. Bei einer leichter fließenden Flüssigkeit enthält das Schaltergehäuse 35 des Flüssigkeitsschalters 34 nicht näher dargestellte Fließdämpfungsmittel.FIG. 6 schematically shows a position difference switch arrangement of a remote control transmitter, which contains a liquid switch 34 as a gravity switch. This liquid switch is arranged on the circuit board 3, which is fixed in position in the sensor housing (not shown) of a remote control transmitter and contains a large, plate-shaped center contact 36 on the bottom of the switch housing 35. For example, four contact elements are distributed around the edge of the top wall of the switch housing 35 37 arranged much smaller area. The switch housing contains a non-wetting, electrically conductive liquid 41, in the amount that it covers only one of the contact elements 37 when the printed circuit board 3 is in a vertical position. From a certain inclination of the circuit board 3 from the horizontal, which corresponds to a trigger angle α₀, the conductive liquid wets it Contact element 37, which is assigned to the direction of the inclination of the circuit board 3 and thus the direction of the inclination of the remote control transmitter and thus creates a conductive connection between the center contact 36 and this contact element 37, so that the gravity switch thus formed is closed in an electrically conductive manner. The four contact elements 37 of the liquid switch 34, of which only three are shown in the drawing, are connected to a direction signal converter 10, which forms a direction-dependent output signal from the signals transmitted via the contacts of the liquid switch, which is transmitted by the remote control transmitter in a transmission signal as a control command remote-controlled electrical device is transmitted. Mercury is particularly suitable as the conductive, non-wetting liquid 41 in the switch housing 35, which has a high flow damping because of its inertia and heaviness. In the case of a more easily flowing liquid, the switch housing 35 of the liquid switch 34 contains flow damping means, not shown in detail.

Bei einem den Figuren 1a und 1b entsprechenden Ausführungsbeispiel eines Fernbedienungsgebers enthält die Lagedifferenzschalteranordnung 17 anstelle von Schwerkraftschaltern 7, 8, 9 mehrereBeschleunigsschalter, die der Einfachheit halber mit den gleichen Bezugszeichen gekennzeichnet sind, wie die Schwerkraftschalter in den Figuren 1a bis 1c. Die Beschleunigungschalter erzeugen bei einer Beschleunigung oberhalb eines bestimmten Beschleunigungsbetrages und in einer bestimmten Beschleunigungsrichtung für die der Beschleunigungsschalter ausgelegt ist, ein Ausgangssignal. Durch eine entsprechende Anordnung der Beschleunigungsschalter 7, 8, 9 mit einer Ausrichtung in die vier hauptsächlichsten Bewegungsrichtungen des Fernbedienungsgebers, nämlich nach oben und unten und nach den beiden Seiten hin melden diese Beschleunigungsgeber durch ihre Ausgangssignale den Schwenkbewegungszustand des Fernbedienungsgebers an einen Richtungssignalwandler 10, der aus diesen Ausgangssignalen ein richtungsabhängiges Ausgangssignal zur Übertragung als Steuerbefehl an ein fernzubedienendes elektrisches Gerät erzeugt.In an exemplary embodiment of a remote control transmitter corresponding to FIGS. 1a and 1b, the position difference switch arrangement 17 instead of gravity switches 7, 8, 9 contains a plurality of accelerator switches which, for the sake of simplicity, are identified by the same reference numerals as the gravity switches in FIGS. 1a to 1c. The acceleration switches generate an output signal when the acceleration is above a certain acceleration amount and in a certain acceleration direction for which the acceleration switch is designed. By an appropriate arrangement of the acceleration switches 7, 8, 9 with an orientation in the four main directions of movement of the remote control transmitter, namely upwards and downwards and towards the two sides, these accelerators report through their output signals the pivoting movement state of the remote control transmitter to a direction signal converter 10, which generates a direction-dependent output signal from these output signals for transmission as a control command to an electrical device to be remote-controlled.

In Figur 7 ist schematisch eine Lagedifferenzschalteranordnung 17 eines Fernbedienungsgebers dargestellt, die auf ein bestimmtes Kraft- oder Strahlungsfeld ansprechende Sensoren 38 enthält. In Figur 7 sind Feldlinien 39 eines derartigen Kraft oder Strahlungsfeldes schematisch eingezeichnet, dessen Intensität die Senoren 38 richtungsabhängig messen und ein dementsprechendes Analogsignal Sa an ihrem Ausgang ausgeben. Die Sensoren 38 sind in dem dargestellten Ausführungsbeispiel in vier unterschiedlichen Wirkungsrichtungen angeordnet, sodaß sie bei einer Messung im allgemeinen unterschiedliche Analogsignale Sa ausgeben. An den Ausgang der Sensoren 38 sind Analogwertspeicher 40 und ein Richtungssignalwandler 10 angeschlossen. Die Ausgänge der Analogwertspeicher 40 sind ebenfalls mit dem Richtungssignalwandler 10 verbunden.FIG. 7 schematically shows a position difference switch arrangement 17 of a remote control transmitter which contains sensors 38 which respond to a certain force or radiation field. Field lines 39 of such a force or radiation field are shown schematically in FIG. 7, the intensity of which the sensors 38 measure in a direction-dependent manner and output a corresponding analog signal Sa at their output. In the exemplary embodiment shown, the sensors 38 are arranged in four different directions of action, so that they generally output different analog signals Sa during a measurement. Analog value memories 40 and a directional signal converter 10 are connected to the output of the sensors 38. The outputs of the analog value memories 40 are also connected to the directional signal converter 10.

Zur Ausgabe eines Steuerbefehles betätigt der Benutzer des Fernbedienungsgebers zunächst die Taste 6 des Einschalters 19 des nicht näher dargestellten Fernbedienungsgebers und führt im betätigten Zustand der Drucktaste 6 die gewünschte Schwenkbewegung des Fernbedienungsgebers durch. Beim Einschalten des Fernbedienungsgebers durch das Betätigen der Taste 6 des Schalters 19 werden in den Analogwertspeichern 40 die von den Sensoren 38 ausgegebenen Analogsingale Sa gespeichert. Diese dienen dann dem Richtungssignalwandler 10 als Referenzwert für die nachfolgende Schwenkbewegung. Anhand dieser Referenzwerte ermittelt der Richtungssignalwandler in einem logischen Prozeß aus den nach der Einspeicherung in die Analogwertspeicher 40 von den Sensoren 38 ausgegebenen Analogwerten die Richtung der Schwenkbewegung und gibt ein dementsprechendes richtungsabhängiges Ausgangssignal Sr an seinem Ausgang aus, das als Steuerbefehl an ein von der Fernbedienung fernzusteuerndes elektrisches Gerät übertragen wird.To output a control command, the user of the remote control transmitter first presses the button 6 of the switch 19 of the remote control transmitter, not shown, and carries out the desired pivoting movement of the remote control transmitter when the push button 6 is actuated. When turning on the Remote control transmitter by pressing the button 6 of the switch 19, the analog signals Sa output by the sensors 38 are stored in the analog value memories 40. These then serve the directional signal converter 10 as a reference value for the subsequent pivoting movement. On the basis of these reference values, the direction signal converter determines the direction of the pivoting movement from the analog values output by the sensors 38 after being stored in the analog value memory 40 and outputs a corresponding direction-dependent output signal Sr at its output, which as a control command to a remote-controlled one electrical device is transmitted.
