Description

Die Erfindung betrifft eine Tastatur zur Eingabe von Steuerbefehlen, wie sie insbesondere auch für die Rufeingabe bei Aufzügen Verwendung findet.The invention relates to a keyboard for the input of control commands, as used in particular for the call input in elevators use.

Aus der US 5,664,667 ist eine Tastatur zur Eingabe von Steuerbefehlen bekanntgeworden, bei der eine Schaltmatte mit Tastern ausgerüstet ist, die auf einen mit elektrischen Schaltkontakten und Schaltkreisen versehenen Print gelegt wird. Die Taster weisen mit Kontakten bestückte Schaltnocken auf, die bei einem Tastendruck direkt auf die zugehörigen Kontakte des Prints wirken und so einen Steuerbefehl auslösen können. Eine ähnliche Tastatur ist auch aus der GB 2 068 643 A bekannt.From US 5,664,667 a keyboard for the input of control commands has become known in which a switching mat is equipped with buttons that is placed on a provided with electrical switching contacts and circuits print. The push-buttons feature switch cams equipped with contacts, which act directly on the corresponding contacts of the print at the push of a button and can thus trigger a control command. A similar keyboard is also known from GB 2 068 643 A.

Bei der vorstehend beschriebenen Tastatur erfolgt die Kontaktauslösung durch eine direkte Berührung des kontaktierten Schaltnockens des Tasters mit dem Print resp. mit der Kontaktfläche auf dem Print. Aufgrund der offenen Konstruktion dieser Tastatur kann Feuchtigkeit zwischen die Schaltmatte und den mit Leiterbahnen und Schaltkontakten versehenen Print eindringen. Dies führt zu einer schnellen Korrosion und/oder Oxidation der Schaltkontakte und Leiterbahnen und kann in der Folge zu Kurzschlüssen und somit zu einer unbefriedigend kurzen Lebensdauer der Tastatur führen. Weiter wird die bei der Bedienung der Tasten aufgebrachte Kraft direkt auf die Kontaktfläche des Prints übertragen und kann bei zu grosser Krafteinwirkung beabsichtigt oder auch unbeabsichtigt zur Zerstörung der Tastatur führen.In the keyboard described above, the contact is triggered by a direct contact of the contacted switching cam of the probe with the print resp. with the contact area on the print. Due to the open construction of this keyboard, moisture can penetrate between the switching mat and the print provided with printed conductors and switching contacts. This leads to rapid corrosion and / or oxidation of the switching contacts and printed conductors and can consequently lead to short circuits and thus to an unsatisfactorily short service life of the keyboard. Furthermore, the force applied during the operation of the keys is transferred directly to the contact surface of the print and can intentionally or unintentionally lead to the destruction of the keyboard if the force is too great.

Der Erfindung liegt die Aufgabe zugrunde eine Tastatur zur Eingabe von Steuerbefehlen der eingangs genannten Art vorzuschlagen, welche die vorgenannten Nachteile nicht aufweist.The invention has for its object to propose a keyboard for the input of control commands of the type mentioned, which does not have the aforementioned disadvantages.

Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass der durch Taster auszulösende Schaltvorgang in einer geschlossenen Einheit in Form einer Lagerplatte stattfindet, die eine Tastaturmatte und eine Folientastatur umfasst, wobei sich die Schaltkontakte in der gegen Feuchtigkeit abgedichteten Folientastatur befinden resp. die Ruferfassung in der gegen Feuchtigkeit abgedichteten Folientastatur stattfindet und die Schaltnocken der Tastaturmatte lediglich Auslösefunktion haben. Die geschlossene Einheit in Form der Lagerplatte stellt zudem eine erhebliche Montageerleichterung dar, da die Tastaturmatte und die Folientastatur bereits fabrikmässig in die Lagerplatte vormontierbar sind und vor Ort lediglich noch ein Tastenblock aufgesetzt werden muss.The advantages achieved by the invention are essentially to be seen in the fact that the triggering by buttons switching operation takes place in a closed unit in the form of a bearing plate comprising a keyboard mat and a membrane keyboard, wherein the switch contacts are in the moisture-sealed membrane keyboard, respectively. the call recording takes place in the moisture-sealed membrane keypad and the switching cam of the keypad have only trigger function. The closed unit in the form of the bearing plate also represents a considerable ease of assembly, since the keypad and the membrane keypad are already factory pre-assembled in the bearing plate and on site only a keypad must be placed.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Tastatur zur Eingabe von Steuerbefehlen möglich. Die auf die geschlossene Einheit aufgesetzten Tasten sind mittels Filmscharniere zu einem Tastenblock zusammengefasst und sind jeweils mit einem Anschlag versehen der auf die Lagerplatte wirkt, so dass auch bei zu grosser Krafteinwirkung auf die Taste nach Kontaktauslösung der Tastenhub durch den Anschlag begrenzt wird.The measures listed in the dependent claims advantageous refinements and improvements of claim 1 keyboard for entering control commands are possible. The attached to the closed unit keys are combined by means of film hinges to a keypad and are each provided with a stop which acts on the bearing plate, so that even with too much force on the key after contact triggering the key stroke is limited by the stop.

Fig. 1 zeigt eine Ansicht einer Folientastatur 1. Diese Folientastatur 1 ist gegen Feuchtigkeitseinflüsse abgedichtet und ist beispielsweise mit fünfzehn Kontakten 2 versehen. Die Anzahl Kontakte 2 kann je nach Grösse beziehungsweise der gewünschten Anzahl auszulösender Signale der Tastatur frei gewählt werden. Weiter besitzen die Kontakte 2 jeweils zwei Kontaktflächen 3, die durch ein Luft- oder Gaspolster voneinander getrennt sind und eine sogenannte Kontaktkammer bilden, wobei dieses Luft- oder Gaspolster die Schaltstrecke darstellt. Wird nun auf einen Kontakt 2 mechanisch Druck ausgeübt, wird das Luft- oder Gaspolster soweit zusammengepresst bis sich die beiden Kontaktflächen 3 berühren und das gewünschte Signal ausgelöst wird. Nach Beendung der Druckausübung auf den Kontakt 2 dehnt sich das Luft- oder Gaspolster wieder in die Ausgangsposition zurück und der Kontakt 2 ist wieder geöffnet. Jeweils mehrere, beispielsweise drei, Kontakte 2 resp. Kontaktkammern sind über, in der Figur nicht dargestellte, Verbindungskanäle zwecks Druckausgleich miteinander verbunden und verbessern dadurch das Schaltverhalten. Diese Folientastatur 1 respektive die durch ein Luft- oder Gaspolster getrennten Kontakte 2 zeichnen sich insbesondere durch die lange Lebensdauer (einige Millionen Schaltvorgänge) sowie die kostengünstige Herstellung aus. Weiter sind in der Folientastatur 1 in Figur 1 nicht dargestellte Leiterbahnen eingelegt, die von den Kontakten 2 über eine Zunge 4 herausgeführt werden, um die Signale in einer Elektronik- oder Steuerungseinheit verarbeiten zu können. Durch die Abdichtung gegen Feuchtigkeit und die isolierte Kontaktauslösung sind die Kontakte 2 und die elektrischen Verbindungen in Form von beispielsweise Leiterbahnen oder Schaltkreisen gegen Verschmutzung, Korrosion oder Oxydation geschützt.1 shows a view of a membrane keyboard 1. This membrane keyboard 1 is sealed against the effects of moisture and is provided, for example, with fifteen contacts 2. The number of contacts 2 can be freely selected depending on the size or the desired number of signals to be triggered on the keyboard. Next, the contacts 2 each have two contact surfaces 3, which are separated by an air or gas cushion and form a so-called contact chamber, said air or gas cushion is the switching path. If mechanical pressure is now exerted on a contact 2, the air or gas cushion is pressed together until the two contact surfaces 3 touch and the desired signal is triggered. After completion of the pressure exerted on the contact 2, the air or gas cushion expands back to the starting position and the contact 2 is opened again. In each case several, for example three, contacts 2 resp. Contact chambers are connected via not shown in the figure, connecting channels for the purpose of pressure equalization and thereby improve the switching behavior. This membrane keypad 1 or separated by an air or gas cushion contacts 2 are characterized in particular by the long life (several million switching operations) and the cost-effective production. Further, in the membrane keyboard 1 in Figure 1, not shown interconnects are inserted, which are led out from the contacts 2 via a tongue 4 in order to process the signals in an electronic or control unit can. By sealing against moisture and the isolated contact release, the contacts 2 and the electrical connections in the form of, for example, tracks or circuits are protected against contamination, corrosion or oxidation.

Um die Folientastatur 1 in einer gemäss Figur 3a und Figur 3b gezeigten Lagerplatte oder Lagertasche 5 genau zu positionieren, werden Öffnungen 6 vorgesehen. Diese Öffnungen 6 sind so angeordnet, dass sie über auf der Lagertasche 5 angebrachte Stifte passen und die Folientastatur 1 somit fixiert wird.To accurately position the membrane keyboard 1 in a bearing plate or bearing pocket 5 shown in FIG. 3a and FIG. 3b, openings 6 are provided. These openings 6 are arranged so that they fit over mounted on the bearing pocket 5 pins and the membrane keyboard 1 is thus fixed.

Figur 2a zeigt die Ansicht und Figur 2b den Seitenriss einer Tastaturmatte 10, die vorzugsweise aus Silikongummi oder einem Material mit ähnlichen Eigenschaften besteht. Die Tastaturmatte 10 besitzt Schaltnocken 11, deren Anzahl und Positionen mit den Kontakten 2 der Folientastatur 1 übereinstimmt. Auch an der Tastaturmatte 10 sind Öffnungen 12 angebracht, so dass die Tastaturmatte 10 über die Stifte der Lagerplatte 5 positioniert wird und die Schaltnocken 11 über den Kontakten 2 der Folientastatur 1 liegen.Figure 2a shows the view and Figure 2b shows the side elevation of a keymat 10, which preferably consists of silicone rubber or a material having similar properties. The keypad 10 has switching cam 11 whose number and positions coincide with the contacts 2 of the membrane keyboard 1. Also on the keypad 10 openings 12 are mounted so that the keypad 10 is positioned over the pins of the bearing plate 5 and the switching cam 11 are above the contacts 2 of the membrane keyboard 1.

Figur 2c zeigt ein vergrösserter Ausschnitt eines Schaltnockens 11 gemäss den Figuren 2a und 2b. Der Schaltnocken 11 besteht im Wesentlichen aus einem Schaltelement 13 und einem Dom 14. Die Dome 14 der Schaltnocken 11 sind jeweils so konstruiert, dass ein definierter Schaltpunkt für das Schaltelement 13 gegeben ist. Das heisst, dass der Dom 14 einen genau definierten Knackpunkt beziehungsweise einen Umkipppunkt aufweist, der bei einer bestimmten Krafteinwirkung auf den Schaltnocken 11 überwunden wird. Das Schaltelement 13 wird dann auf den darunterliegenden Kontakt 2 resp. die Kontaktflächen 3 der Folientastatur 1 gedrückt und löst somit ein Signal aus. Um die Rufauslösung durch das Schaltelement 13 zu ermöglichen, weist die Tastaturmatte 10 im Bereich der Schaltnocken 11 beziehungsweise der Dome 14 Aussparungen 17 auf. Somit kann das Schaltelement 13 auf den darunterliegenden Kontakt 2 der Folientastatur 1 gedrückt werden.FIG. 2c shows an enlarged section of a switching cam 11 according to FIGS. 2a and 2b. The switching cam 11 consists essentially of a switching element 13 and a dome 14. The dome 14 of the switching cam 11 are each constructed so that a defined switching point for the switching element 13 is given. This means that the dome 14 has a precisely defined sticking point or tipping point, which is overcome at a certain force on the switching cam 11. The switching element 13 is then on the underlying contact 2 resp. pressed the contact surfaces 3 of the membrane keyboard 1 and thus triggers a signal. To enable the call triggering by the switching element 13, the keypad 10 in the region of the switching cam 11 and the dome 14 recesses 17. Thus, the switching element 13 can be pressed onto the underlying contact 2 of the membrane keyboard 1.

Gegenüber herkömmlichen Tastaturen unterscheidet sich diese Konstruktion grundsätzlich darin, dass das Schaltelement 13 nicht mit einer Kontaktfläche oder einer Kontaktpille versehen ist, sondern lediglich die Funktion der Rufauslösung hat. Die eigentliche Ruferfassung findet in der abgedichteten Folientastatur 1 durch ein Zusammendrücken der beiden Kontaktflächen 3 statt.Compared to conventional keyboards, this construction basically differs in that the switching element 13 is not provided with a contact surface or a contact pill, but only the function of the call triggering has. The actual call recording takes place in the sealed membrane keypad 1 by compressing the two contact surfaces 3.

Figur 3a zeigt eine Ansicht und Figur 3b einen Seitenriss einer Lagerplatte oder Lagertasche 5. Diese Lagerplatte 5 hat die Aufgabe die Folientastatur 1 und die Tastaturmatte 10 aufzunehmen und zu fixieren. Die Lagerplatte 5 besteht aus einem Oberteil 20 und einem Unterteil 21, die über ein Filmscharnier 22 miteinander verbunden sind. Oberteil 20 und Unterteil 21 sind einstückig, so dass die gesamte Lagertasche 5 in einem Spritzgusswerkzeug in einem Stück herstellbar ist. Das Unterteil 21 weist Verrippungen 28 in Form von Stegen bis auf die Rückwand auf, welche sowohl zur Versteifung der Lagerplatte 5 als auch als Kraftableitung bei zu starkem Druck auf die Tasten dient. Das Oberteil 20 enthält Stifte 23, deren Abstandsraster mit dem der Öffnungen 6 der Folientastatur und dem der Öffnungen 12 der Tastaturmatte 10 entspricht. Weiter sind am Oberteil 20 Öffnungen 24 vorgesehen, deren Abstandsraster dem der Schaltnocken 11 der Tastaturmatte 10 entspricht. Diese Öffnungen 24 dienen dazu, die Verbindung zwischen den Schaltnocken 11 und den Tasten des Tastenblockes 16 herzustellen.FIG. 3a shows a view and FIG. 3b shows a side elevation of a bearing plate or bearing pocket 5. This bearing plate 5 has the task of receiving and fixing the membrane keyboard 1 and the keypad mat 10. The bearing plate 5 consists of an upper part 20 and a lower part 21, which are connected to each other via a film hinge 22. Upper part 20 and lower part 21 are in one piece, so that the entire bearing pocket 5 can be produced in one piece in an injection molding tool. The lower part 21 has ribs 28 in the form of webs up to the rear wall, which serves both to stiffen the bearing plate 5 and as a force dissipation in case of excessive pressure on the keys. The upper part 20 contains pins 23 whose spacing grid corresponds to that of the openings 6 of the membrane keypad and the openings 12 of the keypad mat 10.

Wie in Figur 3b mit einem Pfeil angedeutet ist, wird die Lagerplatte 5 geschlossen, indem der Unterteil 21 über das Filmscharnier 22 auf den Oberteil 20 zugeklappt wird. Um die Lagerplatte 5 auch im geschlossenen Zustand zu halten und zu Verriegeln wird ein Verschluss vorgesehen der ein einmaliges Schliessen erlaubt oder es kann ein Verschluss verwendet werden der zur Wartung wieder geöffnet werden kann. Beispielsweise können am Oberteil 20 Nocken 25, mit kegelförmiger Spitze, angeordnet werden die in Löcher 26 am Unterteil 21 passen, wobei der Durchmesser der Löcher 26 geringfügig kleiner als der grösste Durchmesser der Kegelspitze des Nockens 25 ist.Are in the bearing plate or bearing pocket 5 first the keypad 10 with the switching cam 11 down and then the membrane keypad 1 inserted and each of the openings 6, 12 guided over the pins 23 and thus fixed, the bearing plate 5 can be closed. As indicated in Figure 3b with an arrow, the bearing plate 5 is closed by the lower part 21 is folded over the film hinge 22 on the upper part 20. In order to keep the bearing plate 5 in the closed state and to lock a closure is provided which allows a one-time closure or it can be used a closure which can be opened again for maintenance. For example, cams 25, with a conical tip, which fit into holes 26 on the lower part 21 can be arranged on the upper part 20, wherein the diameter of the holes 26 is slightly smaller than the largest diameter of the apex of the cam 25.

Die geschlossene Lagerplatte oder Lagertasche 5 stellt eine komplette, geschützte und funktionsfähige Einheit dar und erleichtert zudem erheblich die Montage, da die Tastaturmatte 10 und die Folientastatur 1 bereits fabrikmässig in die Lagerplatte 5 vormontierbar sind und vor Ort lediglich noch ein wie in den Figuren 4a und b beschriebener Tastenblock 16 aufgesetzt werden muss. Um den Tastenblock 16 auf der Lagerplatte 5 aufzuschnappen, sind am Oberteil 20 und am Unterteil 21 Befestigungslöcher 27 vorgesehen, die im geschlossenen Zustand der Lagerplatte 5 übereinanderliegen.The closed bearing plate or storage bag 5 is a complete, protected and functional unit and also greatly facilitates the assembly, since the keyboard mat 10 and the membrane keyboard 1 are already factory pre-assembled in the bearing plate 5 and on site only one as in the figures 4a and b described keypad 16 must be placed. In order to snap open the keypad 16 on the bearing plate 5, mounting holes 27 are provided on the upper part 20 and on the lower part 21, which lie one above the other in the closed state of the bearing plate 5.

Figur 4a zeigt einen Seitenriss und Figur 4b eine Ansicht eines Tastenblockes 16. Dieser Tastenblock 16, wie er insbesondere in einer Aufzugsanlage verwendet werden kann, ist beispielsweise eine Zehnertastatur mit weiteren Zusatzfunktionen wie einer Behindertentaste usw., ist einstückig ausgeführt und besteht aus Tasten 30 und einem Rahmenelement 31. Filmscharniere 32 stellen zum einen die Verbindung der Tasten 30 zum Rahmenelement 31 her, zum andern ermöglichen sie die Schaltbewegung der Tasten 30. Der Tastenblock 16 kann vollständig aus Kunststoff bestehen, wobei die Tasten 30 mit Kunststoffhinterspritzten Symbolen und/oder Zahlen versehen sind. Als weitere Variante können die eigentlichen Tasten 30 aus Metall, beispielsweise aus Zinkdruckguss, mit Kunststoff-hinterspritzen Zahlen und Symbolen bestehen, wobei die übrigen Elemente, wie das Rahmenelement 31 und das Filmscharnier 32 aus Kunststoff sind.Figure 4a shows a side elevation and Figure 4b is a view of a keypad 16. This keypad 16, as he can be used in particular in an elevator installation, for example, a ten-key with other additional functions such as a disability button, etc., is made in one piece and consists of keys 30 and a frame member 31. Film hinges 32 make the connection of the keys 30 to the frame member 31, for The keypad 16 may be made entirely of plastic, the keys 30 being provided with plastic injection molded symbols and / or numbers. As a further variant, the actual keys 30 may be made of metal, such as zinc die-cast, numbers and symbols with plastic injection molding, the remaining elements, such as the frame member 31 and the film hinge 32 are made of plastic.

An der Rückseite des Tastenblockes 16 sind Befestigungsstifte 33 angebracht, mit Hilfe deren der Tastenblock 16 auf die geschlossene Lagerplatte 5 aufgeschnappt werden kann, indem die Befestigungsstifte 33 in die zugehörigen Befestigungslöcher 27 der Lagerplatte 5 eingedrückt werden.At the back of the keypad 16 mounting pins 33 are attached, by means of which the keypad 16 can be snapped onto the closed bearing plate 5 by the mounting pins 33 are pressed into the associated mounting holes 27 of the bearing plate 5.

Eine Schaltleiste 34 an der Rückseite jedes Tasters 30 stellt bei einem Tastendruck die Verbindung zum entsprechenden Schaltnocken 11 der Tastaturmatte 10 her, durch den schliesslich die Rufauslösung auf den Kontakt 2 der Folientastatur 1 erfolgt. Ein Anschlag 35 hat die Aufgabe, die Schaltstrecke auf die Schaltnocken 11 zu begrenzen und um bei zu grosser Krafteinwirkung auf den Taster 30 eine Zerstörung der Tastaturmatte 10 oder der Folientastatur 1 zu verhindern, indem der Anschlag 35 auf die Aussenseite der geschlossenen Lagerplatte 5 wirkt.A switching strip 34 on the back of each button 30 provides the connection to the corresponding switching cam 11 of the keypad 10 at a keystroke through which the call triggering finally takes place on the contact 2 of the membrane keypad 1. A stop 35 has the task to limit the switching path to the switching cam 11 and to prevent too much force on the button 30 destruction of the keyboard mat 10 or the membrane keyboard 1 by the stopper 35 acts on the outside of the closed bearing plate 5.

Figur 5 zeigt eine perspektivische Darstellung der gesamten Tastatur. Nach dem Einlegen der Folientastatur 1 und der Tastaturmatte 10 in die offene Lagerplatte 5, wird diese wie mit dem Pfeil angedeutet ist geschlossen und mittels der Nocken 25 verriegelt. Diese geschlossene Einheit kann vormontiert und in der Produktion in kurzer Zeit in das Terminal eingebaut, sowie im Bedarfsfall als Ersatzteil direkt auf die Baustelle geliefert werden. Somit kann während der Montage Zeit eingespart werden und zusätzlich sind die Folientastatur 1 und die Tastaturmatte 10 durch die geschlossene Lagerplatte 5 gegen Beschädigungen geschützt. Weiter wirkt sich auch vorteilhaft aus, dass keine zusätzlichen Befestigungsmittel benötigt werden um die Tastatur zusammenzustellen. Es muss schliesslich nur noch der Tastenblock 16 auf die Lagerplatte 5 aufgeschnappt werden.FIG. 5 shows a perspective view of the entire keyboard. After inserting the membrane keyboard 1 and the keypad mat 10 in the open bearing plate 5, this is indicated as indicated by the arrow is closed and locked by means of the cam 25.
